  • 00:25And maybe you can tell
  • 00:26us a little bit about
  • 00:27what Duke Kunshan University is
  • 00:30as well.
  • 00:31Li Jing is currently an
  • 00:32adjunct professor at Beijing University

  • 02:54So we clearly have an
  • 02:56extremely accomplished,
  • 02:58public health researcher in NCDs
  • 03:00and in implementation
  • 03:02science here with us today,
  • 03:04probably the leader
  • 03:06of this work in
  • 03:08China. And so I'm very
  • 03:09happy to have here and
  • 03:10to turn this over to
  • 03:12doctor.
  • 03:15Yeah. We we need to
  • 03:16make sure we have you
  • 03:17set up properly now.
  • 03:19We probably wanna
  • 03:20maybe minimize this.
  • 03:23Don't show this again. Oh,
  • 03:24maybe yeah. Let's try that.
  • 03:28Oh, maybe I know. Now
  • 03:29we can minimize it over
  • 03:30here,
  • 03:31but the thing would go
  • 03:32away.
  • 03:36Because there's no mouse here.
  • 03:38It's very I have don't
  • 03:39like these keypads. Yeah. An
  • 03:40attached pad. Mhmm.
  • 03:42Say,
  • 03:43yeah. I mean Or click
  • 03:45on somewhere else. Oh, okay.
  • 03:48Sorry.
  • 03:51Denise, you know what to
  • 03:52do? I'm good.
  • 03:53That's the voice mail. It's
  • 03:55not. It's okay.
  • 03:58No. Pull pull that screen
  • 04:00down, and that way, the
  • 04:02thing will, like, go away.
  • 04:05It. Maybe because I did
  • 04:07the laser pointer thing. Yeah.
  • 04:08But I just have to
  • 04:09get to the bar here.
  • 04:11Yeah. And then we're gonna
  • 04:12go here. Now to the
  • 04:13next one. The left. Next
  • 04:15one. Now in Austin. Yeah.
  • 04:17Click that. There you go.
  • 04:19I think now you're in
  • 04:20a good Okay. Well, thank
  • 04:21you so much.
  • 04:23Thank you, Donna for the
  • 04:24invitation.
  • 04:25Thank you, Ally and Denise,
  • 04:27for helping.
  • 04:28I I'm
  • 04:29surprised that Donna read through
  • 04:31the file. Yeah. Yeah. It's
  • 04:33so No. It's so boring.
  • 04:36I hope my talk will
  • 04:37not be so boring. Mhmm.
  • 04:39And, also, of course, I
  • 04:41know Yale, and, I have,
  • 04:43collaborated and know people in,
  • 04:45including, you know, Donna, Professor
  • 04:47Li and others. And one
  • 04:49of my former students, and
  • 04:50he's also here. So, so
  • 04:52glad to see you all.
  • 04:54But this is my very
  • 04:55first time,
  • 04:56in the university in the
  • 04:57city. So, great to be
  • 04:59here. And today, I will
  • 05:01be very focused in talking
  • 05:02about,
  • 05:04this study, which is a,
  • 05:06trial that, for people familiar
  • 05:09with implementation science is the
  • 05:10effectiveness implementation trial.
  • 05:13So
  • 05:14the,
  • 05:17I think I should try
  • 05:18to move this,
  • 05:20below.
  • 05:22That's kind of hard to
  • 05:23do, but it's doesn't it?
  • 05:24So yeah. You can put
  • 05:25it down.
  • 05:26Okay. Now it's working. Sort
  • 05:28of.
  • 05:30And my mortality
  • 05:31view is.
  • 05:34Okay.
  • 05:35So today, I will introduce
  • 05:37this study according to this
  • 05:39paradigm,
  • 05:39that is, called the titles.
  • 05:42You can see what petals
  • 05:44is.
  • 05:45And then I will talk
  • 05:45about revaluation,
  • 05:47which is the s part
  • 05:48of the petals. So let's
  • 05:50take a look at petals.
  • 05:55This works better.
  • 05:57Okay. So this is for
  • 05:59this is proposed by professor,
  • 06:01Roman Xu,
  • 06:02a leader in implementation science
  • 06:04that Donna knows well,
  • 06:06that this is to this
  • 06:08is a model for implementation
  • 06:09research. You can see it
  • 06:10starts with the problem p.
  • 06:12So the real world problem
  • 06:14that we want to address.
  • 06:15And the EBP is the
  • 06:16evidence based practice that we
  • 06:18adopt in the study.
  • 06:20And determinants
  • 06:21actually,
  • 06:22refers to facilitators
  • 06:24and, barriers
  • 06:26for implementation.
  • 06:28And action is the term
  • 06:30used, to show,
  • 06:32to mean implementation
  • 06:33strategies. That's the typical term
  • 06:35in implementation research. And l
  • 06:37is for long term sustainment
  • 06:39of the implementation.
  • 06:41And scale is for,
  • 06:45evaluation and scaling up. So
  • 06:47this is the PEDLS model.
  • 06:49And, you can see PEDLS,
  • 06:51the acronym is gray because
  • 06:53it shows like it's like
  • 06:54the bicycle pedaling.
  • 06:55And, there is this iterative
  • 06:57process and the circle is
  • 06:59showing that. And two other
  • 07:00things to point out is,
  • 07:02one, is the application of
  • 07:04various models and frameworks throughout,
  • 07:07and then also the co
  • 07:08production
  • 07:09process with stakeholders,
  • 07:11are important.
  • 07:13So for our study, what
  • 07:15is the problem that, we
  • 07:17are interested in addressing?
  • 07:19In a nutshell, it's,
  • 07:21stroke prevention and control and
  • 07:23particularly in rural China. So
  • 07:25I would point your attention
  • 07:27to these two figures.
  • 07:29You can see this is
  • 07:30over time from the, early,
  • 07:34century for this one from
  • 07:35nineteen ninety three to twenty
  • 07:37seventeen.
  • 07:38And, the blue one is
  • 07:40urban. The red one
  • 07:42is rural. So in terms
  • 07:44of the prevalence of stroke,
  • 07:46you can see,
  • 07:47the big rise,
  • 07:49in rural China in the
  • 07:51prevalence of stroke to the
  • 07:53point of surpassing,
  • 07:55beyond twenty thirteen. It's passing
  • 07:58on urban areas in terms
  • 07:59of its burden.
  • 08:01However,
  • 08:01in terms of the mortality,
  • 08:03it's being pretty much consistently
  • 08:05higher
  • 08:06than urban areas. The blue
  • 08:08being rural and red being
  • 08:09urban. Green is overall in
  • 08:11the middle. So we have
  • 08:13very large burden and it's
  • 08:15the
  • 08:16number one cause of death
  • 08:18and disability in rural China.
  • 08:20And to to address this
  • 08:21burden, there are so many
  • 08:22evidence based practices already.
  • 08:25Lots of guidelines, clinical guidelines,
  • 08:28even for, a for a
  • 08:29stroke per se. And,
  • 08:32right at the time when
  • 08:33we started,
  • 08:35work on this study, there
  • 08:36is this,
  • 08:39guideline
  • 08:41produced,
  • 08:42in China in Chinese
  • 08:44for the primary care level
  • 08:46stroke prevention and control.
  • 08:48So it's a booklet,
  • 08:50and it's being,
  • 08:52edited by our collaborators in
  • 08:54the tertiary hospital called Tian
  • 08:55Tan Hospital, the leading neurology
  • 08:57hospital in China.
  • 08:58However, even for this, that
  • 09:00is earmarked for primary care,
  • 09:03it turned out to be,
  • 09:05as my question there, it
  • 09:07it's not so easily
  • 09:10applicable
  • 09:11to the reality of primary
  • 09:13care in rural China. So
  • 09:16we set out to do
  • 09:17the study. This is the
  • 09:18site.
  • 09:19Our study,
  • 09:20is conducted
  • 09:21was well, is because it's
  • 09:23still ongoing, conducted in,
  • 09:26one county in this province.
  • 09:28And the province is called
  • 09:29Hebei. It happened to be
  • 09:30my, well, I chose it
  • 09:31to be my hometown.
  • 09:32And this is actually the,
  • 09:35wisest
  • 09:36choice I made, if I
  • 09:37can speak on that.
  • 09:39Because,
  • 09:41this,
  • 09:42was
  • 09:43done in the last few
  • 09:44years of my mom's life.
  • 09:46So because I chose it
  • 09:48here, I was able to
  • 09:48see her, more often than
  • 09:50I had otherwise.
  • 09:52And, but not that's not
  • 09:54the only reason. The other
  • 09:55reasons would be collaborations,
  • 09:57but also the high burden.
  • 09:58You can see, Hebei is
  • 10:00in the darkest,
  • 10:01color in terms of incidence
  • 10:03for stroke.
  • 10:05And Sorry, Nikki. Can you
  • 10:06go back one second? Sure.
  • 10:08So is the whole population
  • 10:10of the Hebei province
  • 10:11three hundred and sixty thousand
  • 10:13people? No. It's the total
  • 10:15population for the county we
  • 10:16chose. Oh, okay. Yeah. Because
  • 10:18I thought that was very
  • 10:19low for China. Right. It's
  • 10:21for this particular county. And
  • 10:23the particular county had two
  • 10:24hundred eighteen villages. We worked
  • 10:25in fifty villages. Okay. Yeah.
  • 10:28So, this is a busy
  • 10:30timeline, but I would like
  • 10:31just to point out there
  • 10:32is this long phase where
  • 10:34we call formative
  • 10:36research where we did, you
  • 10:37know, the barriers and the
  • 10:38facilitators and the comp contextualization,
  • 10:41tailoring.
  • 10:42And then after the pilot
  • 10:44study, we had this intervention
  • 10:46that is only one year
  • 10:47long. So this is important
  • 10:49to keep in mind. The
  • 10:50intervention, the active phase was
  • 10:52only one year long. And
  • 10:54then after that,
  • 10:56after it's over,
  • 10:58we had a hiatus,
  • 11:00during the COVID,
  • 11:02but then we were able
  • 11:03to have follow-up studies,
  • 11:06which, in October of twenty
  • 11:08twenty,
  • 11:09two,
  • 11:10was one of the two
  • 11:11who went to the field
  • 11:12to to to support the
  • 11:14follow-up study.
  • 11:16So, in the for the
  • 11:18barriers and facilitators, we did
  • 11:19three field visits, forty nine
  • 11:21interviews, and four workshops,
  • 11:23and one steering committee meeting,
  • 11:25in order to, do it.
  • 11:27So just quickly for forward
  • 11:29to, the conclusion part of
  • 11:31the determinants
  • 11:33in terms of the barriers.
  • 11:34They actually come from multiple
  • 11:36levels.
  • 11:37At the patient level, there
  • 11:39is the low awareness,
  • 11:40and poor adherence to medication,
  • 11:44and,
  • 11:44poor physical functioning,
  • 11:47generally low health literacy,
  • 11:49And even for the literacy
  • 11:51level among women,
  • 11:53because most of these patients
  • 11:54were older, it is,
  • 11:57less than,
  • 11:59a third of them could
  • 12:00read.
  • 12:02Yeah. So,
  • 12:03at the village doctor level,
  • 12:04there is also the low
  • 12:05awareness on clinical guidelines for
  • 12:07stroke because they focus a
  • 12:09lot of their effort on
  • 12:10maternal and trial health and
  • 12:12other,
  • 12:13conditions such as,
  • 12:15hypertension and diabetes according to,
  • 12:18the National Public Health package.
  • 12:21And they also have low
  • 12:23incentive for preventive care. I'll
  • 12:26get my cell phone for
  • 12:27time control.
  • 12:30Where the lack of preventive
  • 12:32care, and here we focus
  • 12:34on secondary prevention
  • 12:36for stroke,
  • 12:37instead of, the acute phase,
  • 12:39which is not suitable for
  • 12:41the primary care.
  • 12:42At the county level,
  • 12:44they are acute state oriented
  • 12:46and provide fragmented fragmented
  • 12:48care without patient follow-up, and
  • 12:50they're overburdened.
  • 12:52I remember visiting the hospital
  • 12:54during the winter, you know,
  • 12:55around this time.
  • 12:57Outside of the neurology ward,
  • 12:58there will be lots of
  • 12:59deaths and, patients and family
  • 13:02members even living in the
  • 13:04corridor,
  • 13:05because, they they have a
  • 13:07surge of,
  • 13:08patients, during the wintertime.
  • 13:11And then,
  • 13:12our specialists, they are very
  • 13:14experienced,
  • 13:15world class, but they are,
  • 13:16they don't know the rural
  • 13:18situation. So in the county,
  • 13:20this is the three tier,
  • 13:23health care delivery system, county
  • 13:26hospital being only one, and
  • 13:28the leading,
  • 13:29facility.
  • 13:31And then there are fifteen
  • 13:33township health care centers throughout
  • 13:35the county. And then each
  • 13:37county each township
  • 13:38health care centers manages a
  • 13:40number of village clinics,
  • 13:42that is staffed by village
  • 13:43doctors,
  • 13:44and, nurses, sometimes pharmacists too.
  • 13:47And the village doctors
  • 13:49can prescribe medicine. This is
  • 13:51different from, for example, Nepal
  • 13:53or India,
  • 13:54but,
  • 13:55they are not board certified
  • 13:57physicians as you understand them.
  • 14:00They usually receive vocational
  • 14:03professional training of two years
  • 14:05beyond high school or after
  • 14:06middle school.
  • 14:08Then, they get certificate from
  • 14:10the government to be a
  • 14:11village doctor. Some of them
  • 14:13full time, many of them
  • 14:14also part time doing farming
  • 14:16or other things,
  • 14:18on the side. Can I
  • 14:19ask you one question? What?
  • 14:20Can you do that? Sure.
  • 14:21The line about,
  • 14:23poor adherence to treatment. Mhmm.
  • 14:25Just because I don't know
  • 14:26I don't know the context.
  • 14:27Is the adherence because of
  • 14:29access barriers or education or
  • 14:31other things? Things? Yeah. That
  • 14:33is a great question. There
  • 14:34are many reasons. If I
  • 14:36focus on the most important
  • 14:38adherence,
  • 14:39problem, there are
  • 14:41not one there are two.
  • 14:42One is cost.
  • 14:44Some of these medicine are
  • 14:45not free, and, I constantly
  • 14:48hear patients saying, oh, can
  • 14:49we get this for free
  • 14:51or at lower cost? And
  • 14:52the other thing would be
  • 14:53well, the costing we can't
  • 14:55really address in our study.
  • 14:56We didn't address that in
  • 14:57our study. The other thing
  • 14:58is the, health literacy. Like,
  • 15:02they, would stop their medicine
  • 15:04when there is no symptom
  • 15:05or they may forget.
  • 15:07So there's that kind of
  • 15:09reasons.
  • 15:10Sorry,
  • 15:12On the cost question,
  • 15:14can you be how clear
  • 15:16can you be about what
  • 15:18what exactly is free? Like,
  • 15:19a first line WHO
  • 15:22recommended antihypertensives
  • 15:24free.
  • 15:26Are they in stock at
  • 15:27all of these, I guess,
  • 15:28would be village clinics? At
  • 15:30the time time we were
  • 15:31working there, the active trial
  • 15:33from twenty seventeen to twenty
  • 15:34eighteen,
  • 15:35these frontline medicines, what we
  • 15:37call in the essential formulary
  • 15:39Yeah. They are
  • 15:40usually they were usually in
  • 15:42stock.
  • 15:43So availability is not an
  • 15:44issue. However,
  • 15:46in terms of free, at
  • 15:47that time, nothing was completely
  • 15:50for free. They needed to
  • 15:51have co pay.
  • 15:53If they register as a
  • 15:55chronic disease patient
  • 15:57through that special policy, they
  • 15:59get a larger discount, but
  • 16:00it's still not free Mhmm.
  • 16:02At that time.
  • 16:05Later, it became a little
  • 16:06better.
  • 16:07And just to calibrate that,
  • 16:09what percent of, like, the
  • 16:11monthly income
  • 16:12would it cost to pay
  • 16:13for that medicine?
  • 16:15Loss? Well, the medicines we
  • 16:16promote actually are very cheap.
  • 16:18Mhmm.
  • 16:19Like,
  • 16:20they could be just a
  • 16:21few yuan per month or
  • 16:23even
  • 16:24like, aspirin is, like, a
  • 16:25few yuan per year Mhmm.
  • 16:26Which is less than a
  • 16:27dollar per year. Mhmm. But
  • 16:29the better branding
  • 16:31aspirin, like, from there, that
  • 16:33costs more. But that's not
  • 16:34what we're that's not what
  • 16:36we're promoting. Exactly.
  • 16:38And, I don't think I
  • 16:39would remember to mention this,
  • 16:41but some of you may
  • 16:42know,
  • 16:43that it's led by professor,
  • 16:45Jiang He from Tulane who's
  • 16:47at Texas now, and professor
  • 16:49from
  • 16:50China. They published two papers
  • 16:52in Lancet, and I wrote
  • 16:53an editorial for them. They
  • 16:56had this large trial of
  • 16:58three hundred,
  • 16:59or so clusters of thirty
  • 17:01three thousand patients,
  • 17:03with first result of eighteen
  • 17:05months follow-up of a blood
  • 17:06pressure reduction.
  • 17:08It's humongous. It's like fourteen
  • 17:09millimetric
  • 17:10blood pressure reduction
  • 17:11because they provided medicine for
  • 17:13free not because of that.
  • 17:15But the large reason was
  • 17:16that they provided medicine for
  • 17:18free to over ninety percent
  • 17:19of those in the international
  • 17:21are.
  • 17:22That that they did that.
  • 17:23And then in the thirty
  • 17:24six month follow-up, they had
  • 17:26a reduction of somewhere between
  • 17:28fifteen to twenty five percent
  • 17:30in cardiovascular.
  • 17:31So that's their their study.
  • 17:33And, our study
  • 17:35was different,
  • 17:37in
  • 17:38terms of the provision of
  • 17:39medicine.
  • 17:40And we observed a much
  • 17:42smaller
  • 17:43effect size. Because you're using
  • 17:44the health system rather than
  • 17:46providing Yes. We use we
  • 17:47use the existing, system as
  • 17:49much as as we could.
  • 17:51Yeah. I'm sorry. I also
  • 17:52have a question of the
  • 17:53village doctors. Mhmm. So do
  • 17:55they have would you say
  • 17:56that they all have a
  • 17:57high school education?
  • 17:59Some of them would mean,
  • 18:01community college. Uh-huh. So they're
  • 18:02They may not have high
  • 18:03school. They may go to
  • 18:05the vocational school for health
  • 18:07after middle school. But they're
  • 18:09all literate. Sure. Oh, yes.
  • 18:10They're all literate.
  • 18:12And other than, a small
  • 18:13percentage of, let's say, ten
  • 18:16percent ten to fifteen percent
  • 18:17at that time, all of
  • 18:19the village doctors are used
  • 18:20used a smartphone
  • 18:22even in twenty seventeen.
  • 18:24At this time, I think
  • 18:25it's nearly a hundred percent
  • 18:26as the older village doctors,
  • 18:28retired.
  • 18:29However, even as of now,
  • 18:32nearly no patients
  • 18:34use smartphone.
  • 18:37They at least have, had
  • 18:39a shared
  • 18:40cell phone, that is a
  • 18:42feature phone, like a basic
  • 18:43phone. They can receive calls
  • 18:45and text messages.
  • 18:47So But that's very different
  • 18:48than, say, community health workers
  • 18:50in Nepal or ASHA's in
  • 18:52India who could be even
  • 18:54barely literate or even not
  • 18:56literate. Right. That's different. And
  • 18:58so this is a full
  • 18:58time job. They're not volunteers.
  • 19:01They're not volunteers. Some of
  • 19:02them are part time, but
  • 19:04they're paid. They they receive
  • 19:05some payment from the government.
  • 19:07And they are doctors, and
  • 19:09they could even they're not
  • 19:10just literate literate, but they
  • 19:11could prescribe medicine
  • 19:12in the formula, in the
  • 19:14essential formula.
  • 19:16Is it a full time
  • 19:17job, or do they have
  • 19:18another job and they just
  • 19:19do the same size? A
  • 19:21a percentage of them. During
  • 19:22the time when we did
  • 19:23our trial, I think it's
  • 19:24higher now,
  • 19:25because China is changing so
  • 19:27fast.
  • 19:28At that time, about,
  • 19:31I would say, a little
  • 19:32less than half had this
  • 19:33as a full time job.
  • 19:35Mhmm. But the other over
  • 19:37half of the village doctors
  • 19:39worked as a village doctor,
  • 19:41but at the same time,
  • 19:42also did their own business
  • 19:44or farming.
  • 19:46So it's a mix.
  • 19:47But nowadays, more, of them
  • 19:49are full time village doctors.
  • 19:51Okay. Thank you. So these
  • 19:53are important background for you
  • 19:54to understand in our study.
  • 19:56This is the core functions
  • 19:58and core function and forms
  • 20:00model that some of you
  • 20:01may be familiar. So we
  • 20:02start with identification of the
  • 20:04problem that needs and identify
  • 20:06the standardized
  • 20:07core functions,
  • 20:08but tailor the core functions
  • 20:10to,
  • 20:12have the different forms for
  • 20:13the different contexts.
  • 20:15So,
  • 20:16we didn't,
  • 20:17actually use this until later
  • 20:19on,
  • 20:21when we wanted to transfer
  • 20:23learnings from this study to
  • 20:25other settings. And we realized
  • 20:27that this could be used
  • 20:28in a retrospective
  • 20:29way even to facilitate the
  • 20:31transformation,
  • 20:33the transferability.
  • 20:34For example, we could keep
  • 20:35the core functions if we
  • 20:37identify the core functions
  • 20:39to be transferable.
  • 20:41But the forms definitely needs
  • 20:42to be adapted and tailored
  • 20:44to a different context, which
  • 20:45is what we're trying to
  • 20:46do,
  • 20:47in Nepal with Nepal, actually
  • 20:49with Archana,
  • 20:50and,
  • 20:51other Viraj and others, in
  • 20:53Nepal.
  • 20:54So, this is a very
  • 20:55busy slide.
  • 20:57Sorry. Very busy slide, but
  • 21:00I don't mean for you
  • 21:00to read them, but this
  • 21:02is our way of trying
  • 21:03to map what we have
  • 21:04done,
  • 21:05throughout,
  • 21:06this
  • 21:08matrix.
  • 21:10The model that we actively
  • 21:12adopted when we were designing
  • 21:13the intervention,
  • 21:15was,
  • 21:16at that time, was the
  • 21:17chronic care model.
  • 21:19I don't have time to
  • 21:20go into a lot of
  • 21:21details, but it covers,
  • 21:23six domains,
  • 21:24most of them within the
  • 21:25health care system.
  • 21:27Some in, this one is
  • 21:29in the community.
  • 21:30And the emphasis of this
  • 21:32model is on productive
  • 21:34interactions
  • 21:35between
  • 21:36the,
  • 21:38provider team and the patient,
  • 21:40which is also our emphasis,
  • 21:43for the intervention.
  • 21:45So now this is a
  • 21:46revealing of the acronym called
  • 21:48cinema. I've been calling it,
  • 21:49since the outline slide.
  • 21:51It's,
  • 21:52the acronym means,
  • 21:55system integrated,
  • 21:57technology enabled
  • 21:59model of care.
  • 22:01And,
  • 22:02it's,
  • 22:02covering three levels.
  • 22:04So
  • 22:05the, our way of addressing
  • 22:07patient level barriers is through
  • 22:09the monthly follow-up visit by
  • 22:11the village doctors, the interaction
  • 22:13between
  • 22:14the the face to face
  • 22:15interactions between village doctors and
  • 22:17the patients.
  • 22:18And then, we provide self
  • 22:20management support
  • 22:22through the voice messages, and
  • 22:23there is a lot of,
  • 22:25formative research going into why
  • 22:27is voice message not the
  • 22:29text message and how we
  • 22:30design the voice message, etcetera.
  • 22:33And then at the village
  • 22:35doctor level, we have training
  • 22:37and technology empowerment, which is
  • 22:39through a smartphone based app
  • 22:41called the cinema app, and
  • 22:43also incentives.
  • 22:44Incentives both
  • 22:45financial incentives, but also,
  • 22:48nonfinancial
  • 22:49incentives such as recognition,
  • 22:51award,
  • 22:53etcetera.
  • 22:54And then,
  • 22:55working with the specialists,
  • 22:57to
  • 22:58task shift and tax share
  • 23:00with the primary care providers.
  • 23:03Hey, Jane. Can I ask
  • 23:04a question about performance based
  • 23:06incentives?
  • 23:07Yeah.
  • 23:08From my somewhat limited experience
  • 23:11in low and middle income
  • 23:12countries, there's a lot of,
  • 23:14resistance
  • 23:15to performance based incentives
  • 23:18because,
  • 23:19governments
  • 23:20don't wanna kind of create
  • 23:22a dependency where people
  • 23:24don't do their jobs unless
  • 23:26they get an incentive.
  • 23:27And I've also experienced
  • 23:29in a study where I
  • 23:30worked on it. The same
  • 23:32people are, like, the ones
  • 23:33who do a really good
  • 23:34job every single month. I
  • 23:35don't always get the incentives.
  • 23:38So I'm just wondering, like,
  • 23:39since you said you were
  • 23:41co designing with stakeholders
  • 23:42Yes. Were they really happy
  • 23:44about that, and did they
  • 23:45feel it was sustainable?
  • 23:47Or I'm so glad you
  • 23:49thoughts. I'm so glad you
  • 23:50asked this question because I
  • 23:51won't
  • 23:52spend too much time on
  • 23:53this, but this is such
  • 23:54a great question that I
  • 23:55do want to respond to.
  • 23:56Indeed, the concerns are true
  • 23:59that, it may provide the
  • 24:01wrong incentive for people to
  • 24:03just do it
  • 24:04if, you know, they don't
  • 24:05do it well if they
  • 24:06are not getting paid.
  • 24:07And,
  • 24:09it's usually just the better
  • 24:10reform performers.
  • 24:12These are valid concerns. I
  • 24:14would even say I see
  • 24:15that happening in China.
  • 24:17Like, China has this performance
  • 24:19based
  • 24:20system within our national health
  • 24:22care system,
  • 24:23whether it's for the hospitals
  • 24:25or for the public health
  • 24:27package, national public health package.
  • 24:29And they have very detailed
  • 24:31performance measures.
  • 24:33That's usually controlled by the,
  • 24:35county CDC
  • 24:37for the whole county, and
  • 24:38then they evaluate
  • 24:40the the people and then
  • 24:41give them well, having said
  • 24:43that, there is the per
  • 24:44capita fee for the puppy
  • 24:45house plus
  • 24:47some fee that is forewarns
  • 24:48based. So there is this
  • 24:50culture of forewarns based payment
  • 24:52in China. So the resistance
  • 24:54from the government,
  • 24:56officials was low,
  • 24:58but I do see a
  • 24:59problem with that,
  • 25:01that the culture is such.
  • 25:03For example, we're designing another
  • 25:05study. We're trying to create
  • 25:07a culture of, for example,
  • 25:09peer leaders
  • 25:10or community health volunteers.
  • 25:12But the resistance I always
  • 25:14get is, will the volunteers
  • 25:16be paid? If not, they
  • 25:17may not be incentivized.
  • 25:19So so there are I
  • 25:20mean, I'm not saying China
  • 25:21doesn't have a volunteer culture,
  • 25:23but I think that's less
  • 25:24than some other cultures. And
  • 25:25then this room space, payment
  • 25:27scheme is,
  • 25:29is a double edged sword.
  • 25:30Yes.
  • 25:32Given our culture, this seems
  • 25:33to be working well, and
  • 25:35we
  • 25:36really designed the indicators for
  • 25:38performance to be very simple
  • 25:39and is embedded in the
  • 25:40app so they could see,
  • 25:42etcetera. Yeah.
  • 25:45So this is the pilot
  • 25:46study we did in the
  • 25:47four villages,
  • 25:49to,
  • 25:50after the design of the
  • 25:51intervention to, fur further refine
  • 25:54it and tailor it.
  • 25:56Some,
  • 25:57this is in Chinese. You
  • 25:59can't really see it, but
  • 26:00basically,
  • 26:01it's the monthly
  • 26:02follow-up
  • 26:03sheet.
  • 26:04And, we focus on the
  • 26:06medicine,
  • 26:07and the physical activity. There
  • 26:09is the goal setting and
  • 26:10then also reminders,
  • 26:12each month. And so each
  • 26:14patient gets one sheet per
  • 26:15month. So throughout the year,
  • 26:16they get twelve sheets,
  • 26:18as reminders for them.
  • 26:20And this is the APP.
  • 26:21The APP is designed to
  • 26:23be user friendly.
  • 26:25So it's very easy to
  • 26:27use,
  • 26:28and, we learned. I think
  • 26:30it's okay to do that
  • 26:32from the WeChat interface.
  • 26:35WeChat is this popular social
  • 26:36media,
  • 26:38sort of like WhatsApp,
  • 26:39in China.
  • 26:41And then it has multiple
  • 26:42functions
  • 26:43at the back end, but
  • 26:44made it very easy for
  • 26:45the users to navigate.
  • 26:49So this is some screenshots,
  • 26:52of that, APP.
  • 26:54We also,
  • 26:55had
  • 26:58ways to design
  • 27:00the messages,
  • 27:01based on the health belief
  • 27:03system, model,
  • 27:05as well as,
  • 27:06focusing on
  • 27:08the two
  • 27:10evidence based practices,
  • 27:12medication adherence and physical activity.
  • 27:14There are so many things
  • 27:15we could work on,
  • 27:16but, we need it really
  • 27:18to prioritize
  • 27:19to what may generate the
  • 27:20larger impact. So these two
  • 27:22are what we focus on.
  • 27:24I just wanna close your
  • 27:25comment. Why didn't you include
  • 27:27reducing salt intake?
  • 27:29Yes. That's a good question.
  • 27:31For this study, we didn't
  • 27:33do that. I I I've
  • 27:34actually I had many other
  • 27:35studies focusing on that. I
  • 27:37know. But for for this
  • 27:38study, the conscious choice was
  • 27:40not to work on education
  • 27:42I mean, diet related factors
  • 27:44because,
  • 27:46it's it's really comp complicated.
  • 27:48Not because diet is complicated
  • 27:49by itself, but if I
  • 27:51add more components to it,
  • 27:53it may be too complicated.
  • 27:55In indeed, the original proposal
  • 27:57included rehabilitation
  • 27:59Mhmm. As well,
  • 28:00but we decided to cut
  • 28:02that part and just focus
  • 28:03on the medical and the
  • 28:05healthy life lifestyle part. Yeah.
  • 28:08So we didn't, choose
  • 28:10to have a comprehensive
  • 28:12strategy.
  • 28:13Having said that, when we
  • 28:15build on this and now
  • 28:16work in another urban setting,
  • 28:18we do have the salt
  • 28:20reduction
  • 28:21in there.
  • 28:24For the long term sustainability,
  • 28:26this framework, we didn't, have
  • 28:28it at the beginning, but
  • 28:29we designed our whole intervention
  • 28:31with sustainability and scalability in
  • 28:33mind because we don't want
  • 28:35it to just be,
  • 28:37you know, a one time,
  • 28:39kind of effort.
  • 28:41But in but having said
  • 28:42that, this was investigator initiated,
  • 28:46study.
  • 28:46So,
  • 28:48and,
  • 28:49as of now, it's not
  • 28:51being,
  • 28:52scaled up in China.
  • 28:54But I'm hoping with our
  • 28:56most recent result
  • 28:57with, one just,
  • 28:59published to come out on
  • 29:00December thirtieth and another one,
  • 29:02hopefully,
  • 29:03soon,
  • 29:04maybe I will initiate this
  • 29:06thing about scaling up in
  • 29:08China as well. So we
  • 29:10did the,
  • 29:11access,
  • 29:12assessment on sustainability
  • 29:14of the study
  • 29:16in this summer
  • 29:17according to this framework.
  • 29:20So this is the pedal,
  • 29:22of the study.
  • 29:24The problem we address was
  • 29:26the, EBP
  • 29:27we adopt, which is mainly
  • 29:29the monthly follow-up
  • 29:31and medication adherence and physical
  • 29:34activity,
  • 29:35and and our implementation strategies
  • 29:37that addresses the local barriers.
  • 29:41And
  • 29:42now let's, talk about the
  • 29:43evaluation of this intervention.
  • 29:45So in terms of the
  • 29:46evaluation, the
  • 29:48research question as it if
  • 29:50we put it into one
  • 29:51sentence is this,
  • 29:53which is can the,
  • 29:55primary health care providers, we
  • 29:56call them village doctors in
  • 29:58China, they're even if when
  • 29:59they are supported by the
  • 30:00system
  • 30:01and equipped with digital health
  • 30:03technology, can they provide
  • 30:05the essential,
  • 30:06higher quality care
  • 30:08and reduce systolic blood pressure?
  • 30:10So we have this equal
  • 30:12emphasis
  • 30:13on two outcomes,
  • 30:15which makes it a hybrid
  • 30:16two,
  • 30:18trial.
  • 30:19And many of you are
  • 30:20familiar with this. So hybrid
  • 30:22one, the primary on effectiveness,
  • 30:24hybrid three, primary on implementation,
  • 30:26and hybrid two Mhmm. Has
  • 30:27this equal emphasis.
  • 30:29And in their paper published,
  • 30:31by professor Curran et al,
  • 30:33and they talk about, what
  • 30:34makes it a hybrid two
  • 30:36trial. So,
  • 30:38skipping over this part, but
  • 30:39I think this is more
  • 30:40legible.
  • 30:42It talks about the conditions
  • 30:44of when to adopt a
  • 30:46hybrid type two trial.
  • 30:48And, for example, it needs
  • 30:49to be having strong,
  • 30:51face validity
  • 30:53and a strong base of
  • 30:54indirect evidence, a minimal risk,
  • 30:56and there is momentum,
  • 30:58and it should be,
  • 31:00supportable,
  • 31:01in terms of the strategies.
  • 31:03And, there is reason to
  • 31:05gather more data.
  • 31:07And the ideal,
  • 31:08condition is that, there is
  • 31:10reasonably
  • 31:11close
  • 31:12evidence,
  • 31:13and the overall intervention is
  • 31:15not overly complex.
  • 31:16So, our cinema trial actually
  • 31:19fulfills this requirement. For example,
  • 31:21there is strong face validity
  • 31:23for both the EBP
  • 31:25and the implementation strategy,
  • 31:27and the strong indirect evidence
  • 31:29actually came from our own
  • 31:30study
  • 31:31in, rural China and as
  • 31:33well as from,
  • 31:34Tibet
  • 31:35in China.
  • 31:36And then there is,
  • 31:38low risk in the intervention.
  • 31:40We didn't have anything of
  • 31:42new drugs or new measures,
  • 31:43etcetera.
  • 31:45Nothing beyond the implementer, village
  • 31:47doctors,
  • 31:47capability.
  • 31:48And the momentum for implementation
  • 31:51was,
  • 31:52high at that time when
  • 31:54the medical care reform in
  • 31:56China
  • 31:57was really having this push
  • 31:58of strengthening primary care, having
  • 32:00hierarchical,
  • 32:02health care, and task shifting.
  • 32:05And,
  • 32:06the institutional support was very
  • 32:07strong from provincial,
  • 32:09even national level, but more
  • 32:11at the local level.
  • 32:13And there is equipoise
  • 32:15that we don't know the
  • 32:17whole intervention package as we
  • 32:18design them was effective or
  • 32:21not.
  • 32:22So,
  • 32:23you are familiar with this
  • 32:24logic model, like, what do
  • 32:26we put in? What do
  • 32:27we do? What's the immediate
  • 32:29output on the media term
  • 32:31outcome and the long term
  • 32:32impact? So in terms of
  • 32:34our study,
  • 32:35this is the logic model
  • 32:36for our study is color.
  • 32:38The color scheme shows different
  • 32:40levels. Like, this is the
  • 32:41health care system level,
  • 32:43and this is the village
  • 32:45doctor level,
  • 32:46and this is the patient
  • 32:48level,
  • 32:50in in a summary. So
  • 32:52as we design, in terms
  • 32:53of the trial,
  • 32:55it's a cluster randomized trial.
  • 32:57So after we,
  • 33:01do the baseline connect collection,
  • 33:03then we review
  • 33:04the allocation of,
  • 33:07the clusters into each groups.
  • 33:08This is very important because
  • 33:10the for a open label
  • 33:12trial,
  • 33:13inevitably for complex health intervention
  • 33:16like ours, It needs to
  • 33:17be open label. There is
  • 33:18no way that we can
  • 33:19do double blind,
  • 33:21but at least it can
  • 33:22be concealed
  • 33:23for the baseline,
  • 33:27measurement.
  • 33:28And then, it's in a
  • 33:29one to one ratio. So
  • 33:31twenty five
  • 33:32villages in the intervention, twenty
  • 33:34five in control. On average,
  • 33:36twenty five patients per cluster
  • 33:38of, they're all stroke patients,
  • 33:40and we have a quarterly
  • 33:41process evaluation, mostly qualitative research.
  • 33:44And then in terms of
  • 33:45the underlying data collection, it
  • 33:47was also,
  • 33:50designed to be blinded.
  • 33:52Like, the assessors came from
  • 33:55a third party, which is
  • 33:56the CDC staff from a
  • 33:58nearing,
  • 33:59neighboring county, not from the
  • 34:01intervention county itself.
  • 34:03And then they did both
  • 34:04the baseline and the end
  • 34:06line,
  • 34:07according to the same protocol.
  • 34:09And from, my observation that
  • 34:11they didn't care who who's
  • 34:12in the information, who's in
  • 34:13the control. We asked them
  • 34:14not to ask, and they
  • 34:16they just want to do
  • 34:17their job, which is the
  • 34:19outcome assessment,
  • 34:20data, collection and do their
  • 34:22job well. Can you come
  • 34:23back a second? Mhmm. So
  • 34:25my first question is, so
  • 34:26this is an individually randomized
  • 34:28study or something? It's a
  • 34:29cluster randomized trial. Okay. So
  • 34:31So twenty five villages into
  • 34:33each,
  • 34:35three. Okay. Because the way
  • 34:36it says it varies, it
  • 34:37said six twenty five receiving
  • 34:39usual care
  • 34:41and,
  • 34:42and six twenty five receiving
  • 34:44the cinema model. So you
  • 34:45So she should have said
  • 34:46twenty five versus twenty five.
  • 34:48Okay. Yeah. And,
  • 34:49because you wouldn't have exactly
  • 34:51six twenty five in both
  • 34:52groups. You should be in
  • 34:53a real study because
  • 34:55every village would have a
  • 34:56different number of stroke I
  • 34:58I don't have exactly six
  • 34:59twenty five. Sorry. That's very
  • 35:01good catch, Donna. This is
  • 35:02wrong. I should have changed
  • 35:03it,
  • 35:05because,
  • 35:07this is the design. I
  • 35:08mean, the design also is
  • 35:10twenty five versus twenty five.
  • 35:11Yeah. Twenty five versus twenty
  • 35:12five. I mean, I caught
  • 35:13it because this is a
  • 35:14main area research in our
  • 35:16Yeah. Group looking at Yeah.
  • 35:18And I designs and then
  • 35:19I should have caught it
  • 35:20myself. So that's well, I
  • 35:22had another flowchart, but this
  • 35:23is a well, yeah. So
  • 35:25and
  • 35:26I don't think I put
  • 35:27in the final flowchart in
  • 35:28here. Something that's written like
  • 35:30in the back of my
  • 35:31chart. Oh, yeah. Sure. Yeah.
  • 35:33Can you say a little
  • 35:34bit more about what the
  • 35:35Morisky Grain Louvain scale and
  • 35:37the time jump in Vowetesta?
  • 35:40Yeah. So that is the,
  • 35:42four item
  • 35:44medication
  • 35:44adherence scale. And, I'm glad
  • 35:47also, I'm glad you asked
  • 35:48asked because the more famous
  • 35:50one is the eight item,
  • 35:51MMAS,
  • 35:53which is which needs to
  • 35:54be paid. And at Duke
  • 35:55University, we were warned
  • 35:57that don't use it unless
  • 35:58you pay them. Otherwise, even
  • 36:00after you publish, you may
  • 36:01get into lawsuit.
  • 36:02However,
  • 36:03this four item one called
  • 36:05MGLS
  • 36:06is free. So we won't
  • 36:08get into trouble. So that's
  • 36:09what we did. In terms
  • 36:10of the physical function in
  • 36:11the time up and go,
  • 36:13it's a measure
  • 36:14where, we ask them to
  • 36:16sit on the chair, and
  • 36:18we place a mark three
  • 36:19meters away. So we say
  • 36:21begin until they stand up
  • 36:22and walk three
  • 36:24meters. We turn back and
  • 36:25sit down. So we time
  • 36:26that. So if that is,
  • 36:29above fourteen seconds, that means
  • 36:31their functioning is not
  • 36:32too good in terms of
  • 36:34lower.
  • 36:35Alright. And then in terms
  • 36:36of adherence then, the scale
  • 36:38is a self report at
  • 36:40the level of the patient
  • 36:41where they just say yes
  • 36:42or no. They took it
  • 36:43or they didn't. Yes. And
  • 36:44there was no other validation.
  • 36:46No no pill count and
  • 36:47or anything like that. So
  • 36:49this is, one of the
  • 36:50secondary outcomes we have. Yeah.
  • 36:52And then in the follow-up
  • 36:54study, we try to have
  • 36:55other measures, but still not
  • 36:57objective
  • 36:58type, but another scale to,
  • 37:01to assess medication adherence,
  • 37:03which was
  • 37:04done
  • 37:05in this year. Yeah. In
  • 37:07this past summer.
  • 37:09So in terms of this
  • 37:11implementation outcomes framework, you know,
  • 37:13there's implementation outcome, service outcome,
  • 37:15and patient outcome. So we
  • 37:16try to assess, many of
  • 37:19this. So, just quick summaries
  • 37:21of,
  • 37:22in terms of this trial,
  • 37:23the primary outcome,
  • 37:25for implementation
  • 37:26versus effectiveness
  • 37:27and then secondary exploratory.
  • 37:30So,
  • 37:31at the time of the
  • 37:32trial, these outcomes were exploratory,
  • 37:35such as recurrence of stroke,
  • 37:37mortality, hospitalization.
  • 37:39But in the long term
  • 37:40follow-up, because we were able
  • 37:42to accrue enough events,
  • 37:44then, they became primary outcomes
  • 37:46for the long term follow-up,
  • 37:50like,
  • 37:51explained here.
  • 37:53So,
  • 37:55this is more detail that
  • 37:56I'm not gonna spend too
  • 37:57much time on. You can
  • 37:59see our final,
  • 38:00patient count. Fifty villages and,
  • 38:03twelve hundred ninety nine patients.
  • 38:05So it's not exactly six
  • 38:06seventy five versus six seventy
  • 38:08five.
  • 38:10Okay.
  • 38:12One nine one two nine
  • 38:13nine
  • 38:14is the final patient count.
  • 38:16So this is a overview
  • 38:19of the
  • 38:22evaluation,
  • 38:23framework, which is mostly the
  • 38:25RAIN, but also embedded
  • 38:28within the MRC UKMRC
  • 38:30process evaluation framework for complex
  • 38:32interventions.
  • 38:36You can't really read it,
  • 38:38and I have another slide,
  • 38:40showing it. This is from
  • 38:41our process evaluation
  • 38:43implementation outcome paper,
  • 38:45in terms of quotes and
  • 38:46the summary, and this is
  • 38:48the RE AIM framework. So
  • 38:49in summary, in terms of
  • 38:51fidelity,
  • 38:53is reasonable, not,
  • 38:55perfect, but reasonable. For example,
  • 38:58in terms of the training,
  • 38:59eighty four percent attended both
  • 39:01sessions,
  • 39:03and, some only attended the
  • 39:05first one.
  • 39:06And on average, they were
  • 39:08able to perform the monthly
  • 39:10follow-up.
  • 39:11And in terms of the
  • 39:13messages sent out,
  • 39:15I mean, sorry. This is
  • 39:16the WeChat message for the
  • 39:17village doctors as one way
  • 39:19of,
  • 39:20support.
  • 39:22And for the patients, you
  • 39:23can see
  • 39:25there's eleven percent received
  • 39:27less than
  • 39:28monthly visit,
  • 39:30which means,
  • 39:31about,
  • 39:32eighty nine percent received the
  • 39:34monthly visits.
  • 39:35And also,
  • 39:37in terms of the voice
  • 39:38messages though, it was lower.
  • 39:40For example,
  • 39:42we had,
  • 39:43about a little over a
  • 39:45quarter
  • 39:46who,
  • 39:47didn't answer half of the
  • 39:48voice messages. Because, basically, the
  • 39:51way it worked was that
  • 39:52the APP through technical support
  • 39:55at the back end can
  • 39:56automatically send out the messages
  • 39:58to the patients.
  • 40:00And the time is in
  • 40:01the morning when they were
  • 40:02usually at home before they
  • 40:04go out to work,
  • 40:06in the farm. So
  • 40:08they if they pick up
  • 40:09this call, then they get
  • 40:11to hear the message recorded
  • 40:13for them, and it's a
  • 40:14one way. There's no interaction.
  • 40:17It's not designed to be,
  • 40:18so sophisticated.
  • 40:20And,
  • 40:22the message is usually less
  • 40:24than one minute long, so
  • 40:26thirty seconds or less, and
  • 40:28it's repeated one time
  • 40:30in and recorded in, a
  • 40:32local dialect,
  • 40:34by the wife of our
  • 40:36program officer in the country.
  • 40:38So if they picked it
  • 40:40up, that
  • 40:41means they got it. If
  • 40:42not, the system will call
  • 40:44two more times before eight
  • 40:46AM.
  • 40:47And then after that, they
  • 40:49it will be done for
  • 40:50the day. So about a
  • 40:51quarter of them didn't receive
  • 40:53half. So the fidelity here,
  • 40:56is,
  • 40:57less than the other measures.
  • 40:59So in terms of the
  • 41:00summary, we could see,
  • 41:03that
  • 41:04could you go back?
  • 41:05So what I'm wondering is
  • 41:07in terms of these fidelity
  • 41:08indicators,
  • 41:09do you have them, like,
  • 41:11do you have them on
  • 41:12all privileged doctors and all
  • 41:14patients, and how often?
  • 41:17That's a good good question,
  • 41:18actually. It's a question want
  • 41:19to,
  • 41:20consult you later on. This
  • 41:23is for the intervention religious
  • 41:25only, and we have it
  • 41:26on all village doctors, all
  • 41:28patients in the intervention arm.
  • 41:31We don't If you have
  • 41:31an alarm, they wouldn't be
  • 41:32getting any voice mails Right.
  • 41:35Or any of these things.
  • 41:36Right? Right. However,
  • 41:38there is one thing that
  • 41:39we could measure, which is
  • 41:40the monthly visit. We ask
  • 41:41them. Okay.
  • 41:43But, in terms of the
  • 41:44other things,
  • 41:46the WeChat group, or the
  • 41:48voice messages or the APP.
  • 41:50They don't talk about that.
  • 41:51They don't have it. Yeah.
  • 41:52It's gonna be very interesting.
  • 41:53Yeah. So, I think for
  • 41:55the general
  • 41:56outcome, it needs to be
  • 41:57across all the clusters and,
  • 42:00patients, I think.
  • 42:03So this is a summary.
  • 42:04They,
  • 42:06found that,
  • 42:07their
  • 42:09knowledge and capability,
  • 42:11these enablers
  • 42:12being
  • 42:13improved,
  • 42:14and
  • 42:16and there is credibility
  • 42:17credibility for the top down
  • 42:19approach because we work with
  • 42:20the government in implementing this.
  • 42:23And,
  • 42:24in terms of the patient,
  • 42:26they perceive benefits of receiving
  • 42:28the most voice messages.
  • 42:30They appreciated,
  • 42:32the content
  • 42:33designed to be simple and
  • 42:34tailored and give them practical
  • 42:36tips, etcetera, and reminders.
  • 42:40And,
  • 42:41this is the actual flowchart.
  • 42:42I did have it. I
  • 42:43forgot,
  • 42:44because the actual flowchart was
  • 42:46meant to show the long
  • 42:47term follow-up mostly.
  • 42:50So we have one twelve
  • 42:51one two nine nine,
  • 42:53and this is,
  • 42:54three thirty seven, to be
  • 42:56exact in the in twenty
  • 42:58five. And,
  • 43:00the one year follow-up is
  • 43:01that, and the two year,
  • 43:04and then the long term
  • 43:05follow-up,
  • 43:06is reported here. Even if
  • 43:09they were not, some of
  • 43:10them not in the one
  • 43:11year follow-up, they could still
  • 43:13be followed up later on.
  • 43:14And our follow-up rate was
  • 43:16very high. It's above ninety
  • 43:18five percent of all people
  • 43:19who survived.
  • 43:22So this is the main
  • 43:23result,
  • 43:24for the systolic blood pressure.
  • 43:28It's two busy slides, but
  • 43:30you can see,
  • 43:31here,
  • 43:32is the change,
  • 43:34by group. The top one
  • 43:36is
  • 43:38the,
  • 43:39control group. The bottom one
  • 43:40is the intervention group. You
  • 43:42can see the yellow part
  • 43:43is the one year of
  • 43:44active trial part.
  • 43:46There is a large reduction
  • 43:47in both groups,
  • 43:49including the control group. And
  • 43:51then that difference was small.
  • 43:53It's being hidden here, only
  • 43:56about,
  • 43:56two point eight,
  • 43:59millimeter mercury,
  • 44:00but it's significant for, that
  • 44:02lab trial.
  • 44:04And then,
  • 44:05the long in terms of
  • 44:06long term follow-up, you could
  • 44:08see both group increased,
  • 44:10but the difference,
  • 44:11was more or less capped.
  • 44:13So you could see the
  • 44:14net difference,
  • 44:16the result of the test
  • 44:17here is is meant to
  • 44:18see to show the difference
  • 44:20in difference,
  • 44:22also here.
  • 44:23So it's similar in magnitude,
  • 44:25about two point nine or
  • 44:27two point eight millimeter mercury.
  • 44:28So in terms of the
  • 44:29sypholic blood pressure, it was
  • 44:31not that high.
  • 44:32However,
  • 44:33we found that,
  • 44:36they are generally consistent
  • 44:38across the groups,
  • 44:40with stronger impacts among women,
  • 44:43among lower educated
  • 44:45people, among people with lower
  • 44:47income. So in other words,
  • 44:48our intervention
  • 44:50worked better
  • 44:51for the more vulnerable group
  • 44:53even
  • 44:54overall in the resorts limited
  • 44:56setting of rural China.
  • 44:59And this is but I
  • 45:00just wanna look at those
  • 45:01p values for interaction
  • 45:03because none of them are
  • 45:04actually significant.
  • 45:05Yeah. So I'm not saying
  • 45:07there is interaction. I'm saying
  • 45:09that
  • 45:10within
  • 45:11the subgroups,
  • 45:13the intervention effect was stronger
  • 45:15in magnitude.
  • 45:16I think it's accurate to
  • 45:17say it in this way
  • 45:18because we really worked hard
  • 45:19on how to say it
  • 45:20in the paper in this
  • 45:22paper that's coming out soon.
  • 45:24There is a stronger effect
  • 45:26size for the subgroup of
  • 45:29more vulnerable subgroups
  • 45:31in within
  • 45:33that.
  • 45:35Yeah. But the injection wasn't
  • 45:37significant.
  • 45:43And this is the graph
  • 45:44for the mortality. And, again,
  • 45:46you can see this is
  • 45:47the first year,
  • 45:48and there is a small
  • 45:49separation,
  • 45:51but not,
  • 45:53and even then, it was
  • 45:54significant,
  • 45:55but we only had thirty
  • 45:56deaths
  • 45:57back then for exploratory outcome.
  • 46:00But you could see the
  • 46:00separation over time was very
  • 46:02clear and,
  • 46:04if,
  • 46:06significant. In a nutshell,
  • 46:08it's about,
  • 46:09twenty between twenty to thirty
  • 46:11percent relative reduction
  • 46:13in,
  • 46:13cardiovascular,
  • 46:15mortality or all cause mortality
  • 46:17or stroke mortality.
  • 46:19So cost effectiveness, I'm skipping
  • 46:21over the details of the
  • 46:23parameters,
  • 46:24and, just to show the
  • 46:26summary that is highly cost
  • 46:28effective
  • 46:29with a,
  • 46:30incremental cost effectiveness
  • 46:32ratio of, little over eight
  • 46:35hundred per quality.
  • 46:36And the threshold,
  • 46:39for one, or one and
  • 46:40a half GDP per capita
  • 46:42was over twenty three thousand.
  • 46:44So it's highly cost effective.
  • 46:46And
  • 46:47the figures are blocked, but
  • 46:49okay.
  • 46:50So,
  • 46:51coming to the end, I
  • 46:52like to summarize and say,
  • 46:54this summary is not in
  • 46:55terms of the result, but
  • 46:57in terms of,
  • 46:59the intervention itself.
  • 47:00So the core functions
  • 47:02we identify being
  • 47:03task shifting and task sharing,
  • 47:06provider and patient interactions,
  • 47:08and the empowerment
  • 47:10through different,
  • 47:11ways such as training,
  • 47:13such as incentives
  • 47:14and technology.
  • 47:16In terms of the evidence
  • 47:18based practices,
  • 47:20we focus on these three,
  • 47:23follow-up
  • 47:24and medication adherence and physical
  • 47:26activity. And these are the
  • 47:27main implementation strategies of training,
  • 47:30incentives, and mobile house technology.
  • 47:33So, here is one slide
  • 47:35that's in a different scheme
  • 47:36because I want to catch
  • 47:37your attention.
  • 47:38My my, take home message
  • 47:40of summary,
  • 47:41not based just on this
  • 47:43study, but I think it
  • 47:44applies to all of the
  • 47:45implementation studies we did that,
  • 47:47were complex in nature.
  • 47:49So the three
  • 47:51s,
  • 47:53related to the content process
  • 47:54and approach
  • 47:55in terms of the other
  • 47:56two s's I've touched on,
  • 47:58saying that even when we're
  • 48:00designing it, we hope this
  • 48:01is sustainable over time and
  • 48:03scalable over space,
  • 48:05the designing principles,
  • 48:08and the content
  • 48:10is undoubtedly
  • 48:11complex.
  • 48:13It covers multiple levels,
  • 48:15patients and village doctors and
  • 48:17the system support, and it
  • 48:18has technology and all the
  • 48:19different strategies.
  • 48:21But we should try to
  • 48:22keep it simple. And I
  • 48:24think some people know what
  • 48:25this acronym
  • 48:26stand.
  • 48:27K?
  • 48:29Keep it simple stupid. You
  • 48:30know, it's starting from you
  • 48:31know, I I I this
  • 48:33is a reminder to myself
  • 48:34because I tend to make
  • 48:35it more complex. I want
  • 48:36to pack more into it
  • 48:38because I feel, oh, this
  • 48:39is needed. The whole clinical
  • 48:40guideline
  • 48:41is covered so much, but
  • 48:42I remind myself constantly.
  • 48:45If I don't, I'm being
  • 48:46stupid.
  • 48:47And the process, we need
  • 48:48to have a slim and
  • 48:50being streamlined and the approach,
  • 48:52with the digital technology, etcetera,
  • 48:55to be smart.
  • 48:57So
  • 49:00the last slide I have,
  • 49:02other than the
  • 49:03acknowledgments, etcetera,
  • 49:05is,
  • 49:05about sustainability.
  • 49:07I said that we're trying
  • 49:08to learn how to transfer
  • 49:10and adapt to a different
  • 49:11setting such as Nepal.
  • 49:13In fact, I'm working on
  • 49:14the,
  • 49:15multimodility
  • 49:16NIH grant proposal
  • 49:18to focus on, the adaptation
  • 49:20to Nepal. So there's a
  • 49:22lot more to learn. In
  • 49:23terms of sustainability,
  • 49:25I think there's,
  • 49:26also
  • 49:27a lot of studies that
  • 49:29we could do in implementation
  • 49:30research.
  • 49:31I think we need to
  • 49:32differentiate
  • 49:33as a very simple scheme,
  • 49:35differentiate
  • 49:36sustainability versus sustained effects.
  • 49:38For example, we observed
  • 49:40long term outcomes such as
  • 49:42mortality reduction, etcetera, but that
  • 49:44sustained effect. It's not about
  • 49:46the sustainability
  • 49:47of the intervention.
  • 49:49And the intervention being a
  • 49:50bundle or a package,
  • 49:52it includes
  • 49:53both the implementation
  • 49:54strategies and the evidence based
  • 49:56practices altogether
  • 49:58as the intervention bundle.
  • 50:00I think the most important
  • 50:02goal for sustainability is for
  • 50:03the EBP
  • 50:04to go up,
  • 50:06so that, the patients can
  • 50:07reap the benefits in the
  • 50:09long term outcomes.
  • 50:10As for the implementation strategies,
  • 50:12whether we need that to
  • 50:13be so similar or not
  • 50:14depends on whether we need
  • 50:15it or not. Maybe, hopefully,
  • 50:18we don't need that to
  • 50:20go on for a long
  • 50:21time if the evidence based
  • 50:22practices can go on. So
  • 50:24which is,
  • 50:26the case for our study
  • 50:28that, we have, we didn't
  • 50:30continue any of the implementation
  • 50:32strategies such as training
  • 50:34or incentives or technology.
  • 50:36But,
  • 50:37we have evidence to show
  • 50:38that the EBP, which is
  • 50:40the interaction,
  • 50:42the medication assurance, and physical
  • 50:44activity,
  • 50:46some of them were kept.
  • 50:48So so this is,
  • 50:50still,
  • 50:51work in progress, and I
  • 50:52welcome really feedback if you
  • 50:54are interested in sustainability and
  • 50:56scalability.
  • 50:57And, also, I want to
  • 50:58say we didn't explicitly identify
  • 51:00our study.
  • 51:01And, as a hybrid two
  • 51:03trial
  • 51:04in the beginning
  • 51:05until later on because it
  • 51:07this was funded as a
  • 51:08health system trial and etcetera.
  • 51:11So there even in the
  • 51:12professor Kuran's paper, they say,
  • 51:15maybe in the grantsmanship,
  • 51:16whether it's if it's better
  • 51:17for you to say it,
  • 51:18then you say it. Otherwise,
  • 51:20maybe you focus on the
  • 51:21house outcome, which is okay,
  • 51:22but you can do
  • 51:23do it as a high
  • 51:25hybrid type type two.
  • 51:27So this is only a
  • 51:28partial
  • 51:29acknowledgement list,
  • 51:31and my email is here.
  • 51:33So this is, my talk.
  • 51:35I'm sorry I took pretty
  • 51:37long. So only limited time
  • 51:38for questions, but I'm available
  • 51:40here this afternoon.
