- 00:06 --> 00:08Welcome to Yale Cancer Answers
- 00:08 --> 00:10with Doctor Anees Chagpar.
- 00:10 --> 00:12Yale Cancer Answers features the
- 00:12 --> 00:13latest information on cancer care
- 00:14 --> 00:15by welcoming oncologists and
- 00:15 --> 00:17specialists who are on the forefront
- 00:17 --> 00:19of the battle to fight cancer.
- 00:19 --> 00:21This week it's a conversation
- 00:21 --> 00:23about cancer prevention in low
- 00:23 --> 00:25to middle income countries with
- 00:25 --> 00:27Doctor Raul Hernandez Ramirez. Dr.
- 00:27 --> 00:29Hernandez Ramirez is a research
- 00:29 --> 00:30scientist in Biostatistics at
- 00:30 --> 00:33the Yale School of Public Health.
- 00:33 --> 00:34Doctor Chagpar is a professor of
- 00:34 --> 00:36surgical oncology at Yale
- 00:36 --> 00:37School of Medicine.
- 00:38 --> 00:40Maybe we can start off
- 00:40 --> 00:42by you telling us a little bit more
- 00:42 --> 00:44about yourself and what it is you do.
- 00:44 --> 00:47Sure, I'm a research scientist,
- 00:47 --> 00:51I'm a chronic disease epidemiologist with training in
- 00:51 --> 00:53implementation science and
- 00:53 --> 00:54multi level interventions.
- 00:54 --> 00:57I have previous experience
- 00:57 --> 00:59working in Mexico before coming
- 00:59 --> 01:01to Yale to do my PhD and then
- 01:01 --> 01:05become a research faculty, I spent
- 01:05 --> 01:08several years working there in Mexico
- 01:08 --> 01:10at the Nationalist public health.
- 01:10 --> 01:13And regarding the focus of my research,
- 01:13 --> 01:16two of my main areas are cancer
- 01:16 --> 01:17and implementation science.
- 01:18 --> 01:21So talk a little bit more about your
- 01:21 --> 01:24research in terms of cancer prevention,
- 01:24 --> 01:27the intersection of that with
- 01:27 --> 01:31HIV and the work that you do in
- 01:31 --> 01:33low to middle income countries.
- 01:34 --> 01:38A large part of my work
- 01:38 --> 01:43on Cancer Research has been focused on
- 01:43 --> 01:46cancer risk in people living with
- 01:46 --> 01:49HIV in North America. And also on
- 01:49 --> 01:53breast and risk factors for breast and
- 01:53 --> 01:56cervical cancer and now implementation
- 01:56 --> 02:00science in Mexican women
- 02:00 --> 02:02and implementation sciences,
- 02:02 --> 02:05the study of methods to promote
- 02:05 --> 02:06the adoption of
- 02:06 --> 02:10an integration of evidence based practices,
- 02:10 --> 02:12interventions and policies into
- 02:12 --> 02:14routine health care and public health
- 02:14 --> 02:16settings to improve population health.
- 02:16 --> 02:18So it is used to improve the adoption,
- 02:18 --> 02:20appropriate adoption, adaptation,
- 02:20 --> 02:24delivery, and sustainment of effective
- 02:24 --> 02:26interventions by providing clinics,
- 02:26 --> 02:27organizations,
- 02:27 --> 02:29communities and the systems of care.
- 02:29 --> 02:31Regarding the field of
- 02:31 --> 02:33implementation science and cancer,
- 02:33 --> 02:35I'm interested in adopting,
- 02:35 --> 02:38developing, and applying interventions
- 02:38 --> 02:41to increase the uptake of
- 02:41 --> 02:42interventions and practices
- 02:42 --> 02:44for cancer prevention and care,
- 02:44 --> 02:47including prevention strategies to
- 02:47 --> 02:50enable the delivery of those
- 02:50 --> 02:52interventions and their sustainment.
- 02:55 --> 02:56That's pretty broad strokes.
- 02:56 --> 02:58I mean, one would think that
- 02:58 --> 03:01if we kind of break it down
- 03:01 --> 03:03and think about breast cancer,
- 03:03 --> 03:05so we know that breast
- 03:05 --> 03:07cancer is the leading cause
- 03:07 --> 03:11of cancer in women worldwide and one
- 03:11 --> 03:14of the leading cancer causes of cancer
- 03:14 --> 03:17related death in women worldwide,
- 03:17 --> 03:20often tying or competing for
- 03:20 --> 03:23first place with cervical cancer.
- 03:23 --> 03:25But the management of breast cancer
- 03:25 --> 03:28is very different and the screening
- 03:28 --> 03:30availability is very different and
- 03:30 --> 03:33the stage at which breast cancer is
- 03:33 --> 03:36picked up is very different in the US
- 03:36 --> 03:38as is in many low to middle income
- 03:38 --> 03:41countries where the ubiquity
- 03:41 --> 03:44of mammography is not the same as
- 03:44 --> 03:48it is in the US and it may not be
- 03:48 --> 03:49that mammography is necessarily
- 03:49 --> 03:53the be all and end all in low
- 03:53 --> 03:54to middle income countries.
- 03:54 --> 03:56Can you talk a little bit more
- 03:56 --> 03:58about kind of how you've analyzed
- 03:58 --> 04:00the problem of breast cancer in
- 04:00 --> 04:03low to middle income countries,
- 04:03 --> 04:05versus how it is in the United States
- 04:05 --> 04:08and what you think the key issues
- 04:08 --> 04:10are and perhaps some of the
- 04:10 --> 04:12strategies that you've used to address it.
- 04:13 --> 04:17Yeah, so most of my
- 04:19 --> 04:23research in middle income and lower
- 04:23 --> 04:26middle income countries in Mexico
- 04:26 --> 04:29in the terms of breast cancer
- 04:29 --> 04:31was focused on finding risk
- 04:31 --> 04:33factors for breast cancer,
- 04:33 --> 04:38but I would like to talk more given
- 04:38 --> 04:40the different points that you
- 04:40 --> 04:42mentioned in your question about
- 04:42 --> 04:44my work on cervical cancer.
- 04:45 --> 04:47In cervical cancer
- 04:47 --> 04:49like in other cancers as you
- 04:49 --> 04:51were mentioning there is
- 04:51 --> 04:52large variability.
- 04:53 --> 04:54Across the globe,
- 04:54 --> 04:56there is significant variability
- 04:56 --> 04:59in terms of implementing
- 04:59 --> 05:01cancer control programs.
- 05:03 --> 05:06In low and middle income countries
- 05:06 --> 05:08cancer is frequently
- 05:08 --> 05:10diagnosed at advanced stages and
- 05:10 --> 05:12that could be for breast cancer,
- 05:12 --> 05:15as well as for cervical cancer.
- 05:15 --> 05:20And the case of low income countries
- 05:22 --> 05:24there are common barriers
- 05:24 --> 05:26that are barriers that
- 05:26 --> 05:27are not necessarily generalizable
- 05:27 --> 05:30but they are kind of common that
- 05:30 --> 05:32they will be happening and depending
- 05:32 --> 05:33irregardless of whether it's breast cancer or cervical cancer.
- 05:37 --> 05:39And these include the lack of awareness
- 05:39 --> 05:42of the general populations and providers,
- 05:42 --> 05:44lack of access to diagnostic facilities,
- 05:44 --> 05:46long distance travel,
- 05:46 --> 05:50time to locations with cancer services.
- 05:50 --> 05:52And difficulties to implement conventional
- 05:52 --> 05:55screening and other cancer prevention
- 05:55 --> 05:57control methods due to the lack of
- 05:57 --> 05:58financial resources and expertise,
- 05:58 --> 06:01and there are also sociocultural factors
- 06:01 --> 06:04and stigma in the case of cervical cancer.
- 06:04 --> 06:06Despite being nearly fully preventable,
- 06:06 --> 06:08large disparities in incidence and
- 06:08 --> 06:11mortality exist globally and domestically.
- 06:11 --> 06:14It is the fourth most common cancer
- 06:16 --> 06:19and most common cause of
- 06:19 --> 06:22cancer death in the world.
- 06:22 --> 06:24But 85% of those deaths occur
- 06:24 --> 06:28in low and middle income countries.
- 06:28 --> 06:31Then regarding screening also,
- 06:31 --> 06:32they desire large variability,
- 06:32 --> 06:36with about 3 out of five women having
- 06:36 --> 06:38cervical cancer screening ever in
- 06:38 --> 06:41their lives in high income countries,
- 06:41 --> 06:43while it's only about 2 or less out of
- 06:43 --> 06:46five women that have ever been screened
- 06:46 --> 06:48in low and middle income countries,
- 06:48 --> 06:51with some countries like subsaharan
- 06:51 --> 06:53Africa presenting the lowest
- 06:53 --> 06:56coverage with a prevalence very low.
- 06:56 --> 07:00At a medium prevalence of 17%
- 07:00 --> 07:01coverage of screening.
- 07:07 --> 07:09Women in Mexico are three times
- 07:09 --> 07:12more likely to die from cervical cancer
- 07:12 --> 07:15than in the US but even within the US,
- 07:15 --> 07:17US Hispanic women are more
- 07:17 --> 07:19likely to be diagnosed with
- 07:19 --> 07:22and die from cervical cancer
- 07:22 --> 07:25than US non Hispanic white women.
- 07:25 --> 07:28In fact, in Mexico cervical cancer is the
- 07:28 --> 07:31second most common cause of cancer mortality
- 07:31 --> 07:33among women, while in contrast,
- 07:33 --> 07:38is the 12th most common cause of cancer
- 07:38 --> 07:41mortality among women in the US.
- 07:41 --> 07:43And screening for cervical
- 07:43 --> 07:44cancer is effective.
- 07:44 --> 07:48The Pap smear and HPV are evidence
- 07:48 --> 07:51based HPV testing are evidence
- 07:51 --> 07:54based preventive interventions.
- 07:54 --> 07:56However, in the case of Pap smear,
- 07:56 --> 07:59unlike in high income countries
- 07:59 --> 08:01where cervical cancer screening
- 08:01 --> 08:03programs have resulted
- 08:03 --> 08:05in a dramatic decrease in incidence
- 08:05 --> 08:07of mortality in Mexico and other
- 08:07 --> 08:08low and middle income countries,
- 08:08 --> 08:10the impact of these programs
- 08:10 --> 08:12has thus far been limited.
- 08:14 --> 08:19Colposcopy as well
- 08:22 --> 08:24for cervical cancer screening
- 08:24 --> 08:27as I say is a pap smear and also
- 08:27 --> 08:29the HPV test.
- 08:30 --> 08:32And in other places in the
- 08:32 --> 08:35world there is also the visual
- 08:35 --> 08:36inspection with acetic acid.
- 08:36 --> 08:39So let me pause here for a moment
- 08:39 --> 08:41and just ask a question, which is,
- 08:41 --> 08:44you know, before we get into screening,
- 08:44 --> 08:45you had mentioned,
- 08:45 --> 08:47I mean certainly as an epidemiologist
- 08:47 --> 08:49you're interested in risk factors.
- 08:49 --> 08:51One of the interesting points that
- 08:51 --> 08:53you just raised is not only is
- 08:53 --> 08:55mortality of cervical cancer higher
- 08:55 --> 08:57in Mexico than it is in the US,
- 08:57 --> 08:58three times higher,
- 08:58 --> 09:00but Hispanic women in the US
- 09:00 --> 09:03also have a higher rate of
- 09:03 --> 09:05mortality from cervical cancer than
- 09:05 --> 09:08the rest of the American population.
- 09:08 --> 09:11So that raises the issue of
- 09:11 --> 09:14is there a genetic component
- 09:14 --> 09:18here in terms of race, slash,
- 09:18 --> 09:19ethnicity,
- 09:19 --> 09:24or is this really more grounded in
- 09:24 --> 09:28sociocultural and socioeconomic factors?
- 09:29 --> 09:32Yeah, I believe it will be more
- 09:32 --> 09:34grounded in those socio economical
- 09:34 --> 09:36and cultural factors as well,
- 09:36 --> 09:39and also related to cancer
- 09:39 --> 09:42disparities that exist and stigma.
- 09:42 --> 09:45From the perspective of these patients,
- 09:45 --> 09:47but also the services that are being
- 09:47 --> 09:50provided that may not reach the
- 09:50 --> 09:52populations that need those services
- 09:52 --> 09:55and in the case of risk factors,
- 09:55 --> 09:57for cervical cancer
- 09:59 --> 10:01one of the preventive interventions
- 10:01 --> 10:05is the vaccination with HPV, but
- 10:05 --> 10:07since that occurs at early ages,
- 10:07 --> 10:10you have older populations of
- 10:10 --> 10:13women that were not
- 10:13 --> 10:16vaccinated when they were younger
- 10:16 --> 10:20and that they still need to have
- 10:20 --> 10:23the basic prevention screening with
- 10:23 --> 10:27this cytology and follow-up care with
- 10:27 --> 10:31colposcopy to diagnose and treat.
- 10:33 --> 10:37And those are some of those services
- 10:37 --> 10:39we in the US and also when
- 10:39 --> 10:40comparing the US with Mexico,
- 10:40 --> 10:45the rates of those services are lower.
- 10:45 --> 10:48Which leads to a delay in
- 10:48 --> 10:52diagnosis and detecting cancers and
- 10:52 --> 10:55therefore detecting cancers at higher stages,
- 10:55 --> 10:56late stages,
- 10:56 --> 10:59in which they are more difficult to treat.
- 11:00 --> 11:03You know, one of the interesting things,
- 11:03 --> 11:06one of the really wonderful things
- 11:06 --> 11:09that was reported by the American
- 11:09 --> 11:12Cancer Society just recently was a
- 11:12 --> 11:14dramatic fall in the mortality from
- 11:14 --> 11:17cervical cancer in this country,
- 11:17 --> 11:19which they felt was in large
- 11:19 --> 11:22part due to the vaccine.
- 11:22 --> 11:25One of the things that you mentioned was,
- 11:25 --> 11:27you know, financial considerations,
- 11:27 --> 11:28access considerations.
- 11:28 --> 11:31Certainly the health care
- 11:31 --> 11:34workforce in low to middle
- 11:34 --> 11:36income countries is substantially
- 11:36 --> 11:39reduced when compared to the US.
- 11:39 --> 11:42It may be more difficult
- 11:42 --> 11:45for people to access care.
- 11:45 --> 11:49But in the US, the vaccine is available.
- 11:49 --> 11:52In the US, Pap smears are available.
- 11:52 --> 11:56So why do you think it is that
- 11:56 --> 12:00Hispanic women in the US
- 12:00 --> 12:02still have higher rates?
- 12:02 --> 12:06Talk more about the
- 12:06 --> 12:07sociocultural factors that
- 12:07 --> 12:11you think may play in or do you
- 12:11 --> 12:13think that this is predicated also
- 12:13 --> 12:15on the fact that Hispanic women
- 12:15 --> 12:18there may be confounding by the
- 12:18 --> 12:21fact that they tend to be of lower
- 12:21 --> 12:22socioeconomic status and
- 12:22 --> 12:25may still even though there are
- 12:25 --> 12:28such services here in the US,
- 12:28 --> 12:30that they access them at a lower rate.
- 12:30 --> 12:33And perhaps you can talk a little bit
- 12:33 --> 12:35about the comparison between Hispanic
- 12:35 --> 12:39women in the US versus in Mexico.
- 12:40 --> 12:45I think that part of reduced access is
- 12:50 --> 12:53socioeconomical aspects as well as
- 12:53 --> 12:56other things related to
- 12:56 --> 12:58knowledge of cervical cancer
- 12:58 --> 13:01and this screening test and the
- 13:01 --> 13:03benefit of getting them performed
- 13:03 --> 13:05for preventing cervical cancer
- 13:05 --> 13:07and the fear of the test as well.
- 13:07 --> 13:10So those kinds of things may be
- 13:10 --> 13:12interrelated in some way with a
- 13:12 --> 13:14low literacy and in some cases
- 13:14 --> 13:16in women and Hispanic women in
- 13:16 --> 13:18the US and loss of economical
- 13:18 --> 13:24status and also others related to that.
- 13:24 --> 13:28Also it has been reported barriers such as
- 13:30 --> 13:33in low and middle income countries,
- 13:33 --> 13:37it happens too that barriers relate to the
- 13:37 --> 13:39distance or the travel time to get into
- 13:39 --> 13:42the colposcopy because of having to lose
- 13:42 --> 13:45time that women can be working or
- 13:45 --> 13:48taking care of children
- 13:48 --> 13:50if they support the family.
- 13:50 --> 13:53Which brings us to the really good point,
- 13:53 --> 13:55which we're going to pick up right after
- 13:55 --> 13:58the break on the implementation science.
- 13:58 --> 14:00We have a general idea of
- 14:00 --> 14:03some of the factors that might be at play,
- 14:03 --> 14:05but what can we really do about it?
- 14:05 --> 14:07Funding for Yale Cancer Answers
- 14:07 --> 14:09comes from Smilow Cancer Hospital,
- 14:09 --> 14:11where their Center for
- 14:11 --> 14:12Gastrointestinal Cancers provides
- 14:12 --> 14:14patients with a comprehensive,
- 14:14 --> 14:16multidisciplinary approach to
- 14:16 --> 14:18the treatment of GI cancers.

- 14:22 --> 14:24Breast cancer is one of the
- 14:24 --> 14:25most common cancers in women.
- 14:25 --> 14:27In Connecticut alone,
- 14:27 --> 14:29approximately 3500 women will be
- 14:29 --> 14:31diagnosed with breast cancer this year,
- 14:31 --> 14:33but there is hope thanks
- 14:33 --> 14:34to earlier detection,
- 14:34 --> 14:35non invasive treatments,
- 14:35 --> 14:37and the development of novel
- 14:37 --> 14:39therapies to fight breast cancer,
- 14:39 --> 14:41women should schedule a baseline
- 14:41 --> 14:43mammogram beginning at age 40 or
- 14:43 --> 14:45earlier if they have risk factors
- 14:45 --> 14:46associated with the disease.
- 14:46 --> 14:48With screening, early detection,
- 14:48 --> 14:50and a healthy lifestyle,
- 14:50 --> 14:52breast cancer can be defeated.
- 14:52 --> 14:54Clinical trials are currently
- 14:54 --> 14:56underway at federally designated
- 14:56 --> 14:58Comprehensive cancer centers such
- 14:58 --> 15:00as Yale Cancer Center and Smilow
- 15:00 --> 15:02Cancer Hospital to make innovative
- 15:02 --> 15:04new treatments available to patients.
- 15:04 --> 15:06Digital breast tomosynthesis,
- 15:06 --> 15:07or 3D mammography,
- 15:07 --> 15:10is also transforming breast
- 15:10 --> 15:12cancer screening by significantly
- 15:12 --> 15:13reducing unnecessary procedures
- 15:13 --> 15:16while picking up more cancers.
- 15:16 --> 15:18More information is available
- 15:18 --> 15:19at yalecancercenter.org.
- 15:19 --> 15:22You're listening to Connecticut public radio.
- 15:22 --> 15:24Welcome back to Yale Cancer Answers.
- 15:24 --> 15:26This is doctor Anees Chagpar
- 15:26 --> 15:28and I'm joined tonight by my
- 15:28 --> 15:30guest doctor Hernandez Ramirez.
- 15:30 --> 15:32We're talking about cancer prevention
- 15:32 --> 15:34in low to middle income countries
- 15:34 --> 15:37and right before the break Raul was
- 15:37 --> 15:39telling us more about cervical cancer
- 15:39 --> 15:42which is a leading cause of cancer
- 15:42 --> 15:45related mortality around the world.
- 15:45 --> 15:48Interestingly, the rate of mortality
- 15:48 --> 15:51has dropped here in the US.
- 15:51 --> 15:54But one of the startling statistics
- 15:54 --> 15:57that he raised is that not only is
- 15:57 --> 16:00the mortality higher in Mexico
- 16:00 --> 16:03amongst women with cervical cancer,
- 16:03 --> 16:06but also among Hispanic women
- 16:06 --> 16:08right here in the US.
- 16:08 --> 16:10And there are a number of factors
- 16:10 --> 16:13that go into that whether it's a
- 16:13 --> 16:15distance to a treatment facility,
- 16:15 --> 16:18whether it's the availability of PAP smears,
- 16:18 --> 16:21whether it is low social
- 16:21 --> 16:22Health literacy,
- 16:22 --> 16:25whether it's low socioeconomic
- 16:25 --> 16:28status or whether it's cultural
- 16:28 --> 16:32factors that may impact the stigma
- 16:32 --> 16:35associated with cervical cancer,
- 16:35 --> 16:37whether it's lack of vaccines, many,
- 16:37 --> 16:39many factors could go into this.
- 16:39 --> 16:40So, Raul,
- 16:40 --> 16:42the other thing that you had mentioned
- 16:42 --> 16:45to us before the break is that you're
- 16:45 --> 16:47very involved in implementation science this
- 16:47 --> 16:48idea that
- 16:48 --> 16:51you actually try to make a difference,
- 16:51 --> 16:55and change some of the factors
- 16:55 --> 16:58that are going on in populations
- 16:58 --> 17:01to enhance prevention.
- 17:01 --> 17:03So can you talk about some of
- 17:03 --> 17:04the strategies that you've looked
- 17:04 --> 17:06at and some of your results?
- 17:08 --> 17:10Yeah, sure. So as you mentioned,
- 17:10 --> 17:13there are several common variants, right,
- 17:13 --> 17:17that have been reported in lower middle
- 17:17 --> 17:20income countries and other places and
- 17:20 --> 17:22what we have learned from
- 17:22 --> 17:24this work that we are doing in
- 17:24 --> 17:27low and middle income countries?
- 17:27 --> 17:29And this is related to the
- 17:29 --> 17:31implementation science part is
- 17:31 --> 17:33that there are promising health
- 17:33 --> 17:35interventions that have limited impact
- 17:35 --> 17:37in low and middle income countries,
- 17:37 --> 17:40because there are implementation problems,
- 17:40 --> 17:42so there are barriers to implement
- 17:42 --> 17:44these prevention and care practices,
- 17:44 --> 17:46even the basic ones.
- 17:46 --> 17:48And that's the key challenge
- 17:48 --> 17:50to reducing the cancer burden,
- 17:50 --> 17:51the cervical cancer burden in particular
- 17:51 --> 17:53in low and middle income countries.
- 17:53 --> 17:57So the barriers need to be identified
- 17:57 --> 18:00and addressed and that is where
- 18:00 --> 18:03implementation science plays a role.
- 18:03 --> 18:05Implementation science can help
- 18:05 --> 18:08to identify what are those
- 18:08 --> 18:10factors that influence implementation
- 18:10 --> 18:14and then to try to
- 18:14 --> 18:17select and develop intervention
- 18:17 --> 18:21strategies to address those factors
- 18:21 --> 18:24and enable implementation.
- 18:24 --> 18:27My work in Mexico,
- 18:27 --> 18:29we have seen that there are
- 18:29 --> 18:32frequent gaps in screening and follow
- 18:32 --> 18:34up care after abnormal screens.
- 18:34 --> 18:37And the reason for those
- 18:37 --> 18:39gaps may be addressable so
- 18:39 --> 18:42to investigate the reasons for poor
- 18:42 --> 18:44follow up of abnormal screen in Mexico,
- 18:44 --> 18:46we have established a research group
- 18:46 --> 18:49between a group of researchers at Yale and
- 18:49 --> 18:51Mexico's National Autonomous University,
- 18:51 --> 18:55UNAM and the National Institute of
- 18:55 --> 18:57Public Health in Spain and Mexico.
- 18:57 --> 18:59And we started by looking at data
- 18:59 --> 19:01from a group of patients that were
- 19:01 --> 19:03recommended to get a colposcopy
- 19:03 --> 19:05after testing positive for HPV.
- 19:07 --> 19:09In some screening demonstration
- 19:09 --> 19:12studies in Mexico Clinic that
- 19:12 --> 19:14was among uninsured populations.
- 19:14 --> 19:17And we have identified factors positively
- 19:17 --> 19:20linked to follow-up of positive HPV results.
- 19:20 --> 19:23And those include having a history
- 19:23 --> 19:25of PAP and providing contact data.
- 19:25 --> 19:28Those were associated with greater
- 19:28 --> 19:31adherence to obtaining screening test
- 19:31 --> 19:33results before getting a
- 19:33 --> 19:36colposcopy appointment we may need
- 19:36 --> 19:39to get their test results.
- 19:39 --> 19:41Then also the availability of
- 19:41 --> 19:43family medicine service and
- 19:43 --> 19:46being attended by nurses with
- 19:46 --> 19:48a good amount of experience was
- 19:48 --> 19:51associated with greater adherence to
- 19:51 --> 19:52obtaining those screened results.
- 19:52 --> 19:53In contrast,
- 19:53 --> 19:55as mentioned before also observing
- 19:55 --> 19:57in other places,
- 19:57 --> 19:59the longer travel time to colposcopy
- 19:59 --> 20:01clinic were linked to decreased attendance.
- 20:01 --> 20:05So interventions to improve follow
- 20:05 --> 20:08up for those with abnormal results can
- 20:08 --> 20:10be developed based on this information.
- 20:10 --> 20:13Such as strategies that can be
- 20:13 --> 20:15used to secure contact data.
- 20:15 --> 20:16Also,
- 20:16 --> 20:19there could be educational interventions,
- 20:21 --> 20:23skills relative to the cervical
- 20:23 --> 20:25cancer program recommendations,
- 20:25 --> 20:27especially emphasizing the importance
- 20:27 --> 20:30of encouraging patients to promptly
- 20:30 --> 20:32collect their screening results
- 20:32 --> 20:34and get follow-up care if needed.
- 20:34 --> 20:34And also,
- 20:34 --> 20:36in the case of the travel or
- 20:36 --> 20:38the long distance barrier,
- 20:38 --> 20:40to provide travel support for
- 20:40 --> 20:41patients that need a colposcopy
- 20:42 --> 20:44or even taking the clinic to the
- 20:44 --> 20:45communities with a mobile
- 20:45 --> 20:46Scope clinic.
- 20:46 --> 20:48Those sound like
- 20:48 --> 20:51good strategies, but you know,
- 20:51 --> 20:54as I've found with global oncology,
- 20:54 --> 20:56there's always multiple layers to
- 20:56 --> 20:59the onion and the puzzle always seems
- 20:59 --> 21:02to be a little bit more complicated
- 21:02 --> 21:04than you would initially anticipate.
- 21:04 --> 21:08So for example, the idea of,
- 21:08 --> 21:10you know, providing education for
- 21:10 --> 21:13nurses so that they may understand
- 21:13 --> 21:16cervical cancer and its prevention
- 21:16 --> 21:19and treatment in a greater detail sounds
- 21:19 --> 21:22like that's a great idea, and it is,
- 21:22 --> 21:25but for many low to middle income countries
- 21:25 --> 21:28the problem is not only the
- 21:28 --> 21:29lack of knowledge,
- 21:29 --> 21:32it's the lack of nurses.
- 21:32 --> 21:36So how do you get around issues like a
- 21:36 --> 21:39lack of a workforce or a workforce that
- 21:39 --> 21:43is so constrained because it is so small
- 21:43 --> 21:45it doesn't meet World Health Organization
- 21:45 --> 21:48guidelines for the number of nurses that
- 21:48 --> 21:50are recommended for their population,
- 21:50 --> 21:53and so these nurses are working so
- 21:53 --> 21:56many hours that they may not have
- 21:56 --> 22:00time to attend educational activities,
- 22:00 --> 22:02on top of which, even if they did,
- 22:02 --> 22:05they still are very limited in their numbers.
- 22:05 --> 22:08How do you get around the fact that
- 22:08 --> 22:10even if you provide transportation
- 22:10 --> 22:13to patients to get to the clinic,
- 22:13 --> 22:15that many of them,
- 22:15 --> 22:18as you mentioned before the break,
- 22:18 --> 22:20may be working maybe two or three
- 22:20 --> 22:23jobs and maybe getting off from work,
- 22:23 --> 22:24maybe another barrier.
- 22:24 --> 22:27So how do you deal with all of these
- 22:27 --> 22:29layers of the onion?
- 22:29 --> 22:31Very good question.
- 22:31 --> 22:33There are multiple different
- 22:33 --> 22:35layers and because of that reason,
- 22:35 --> 22:37we are now preparing to conduct
- 22:37 --> 22:39research consisting of interviews and
- 22:39 --> 22:41surveys with patients and providers
- 22:41 --> 22:44to try to identify and understand
- 22:44 --> 22:47how those different factors at
- 22:47 --> 22:49different levels work
- 22:49 --> 22:52that affects the individuals.
- 22:52 --> 22:53In this case,
- 22:53 --> 22:54the patients receive the services,
- 22:54 --> 22:57but also what are those factors
- 22:57 --> 22:59related to the providers
- 22:59 --> 23:02that may be affecting implementation,
- 23:02 --> 23:05such as the lack of human resources,
- 23:05 --> 23:08but also the lack of time
- 23:08 --> 23:12to get to attend the
- 23:12 --> 23:13patients but also of course
- 23:14 --> 23:16time to see the patients,
- 23:16 --> 00:-01they will have time to
- 23:18 --> 23:19get additional trainings, right.
- 23:19 --> 23:22So we also need to see what
- 23:22 --> 23:24are kind of the barriers and
- 23:24 --> 23:27your level like organizational
- 23:27 --> 23:31levels that can also influence
- 23:31 --> 23:34the factors.
- 23:34 --> 23:36Going down to the patient
- 23:36 --> 23:38if there are things that can be
- 23:38 --> 23:39changed at the organization
- 23:39 --> 23:41level that it may be more
- 23:41 --> 23:43challenging but that may affect all
- 23:43 --> 23:47the other different levels and
- 23:47 --> 23:49the way is challenging because there
- 23:49 --> 23:51are things that are more modifiable
- 23:51 --> 23:53or easily modifiable than others.
- 23:53 --> 23:55But I think the first step is trying
- 23:55 --> 23:57to generate the evidence about
- 23:57 --> 23:59what is driving the problem in
- 23:59 --> 24:01this particular setting,
- 24:01 --> 24:05and with that evidence, try to
- 24:05 --> 24:08make changes at the higher level to
- 24:08 --> 24:10influence some program and
- 24:10 --> 24:14policies changes based on that and
- 24:14 --> 24:16hopefully with that information
- 24:16 --> 24:18in the case of things that are
- 24:18 --> 24:19harder to modify,
- 24:19 --> 24:22try to generate that evidence that can help.
- 24:22 --> 24:26Also get additional funding for
- 24:26 --> 24:29the clinics to have
- 24:29 --> 24:31in some cases where they have been
- 24:31 --> 24:34done in some places to have
- 24:34 --> 24:36community health workers that are
- 24:36 --> 24:39not patient navigators that dedicate
- 24:39 --> 24:42themselves to the patient
- 24:42 --> 24:44from the beginning of screening to
- 24:44 --> 24:47treatment through all the different steps.
- 24:50 --> 24:52An important part there is,
- 24:52 --> 24:55this part of getting the financial
- 24:55 --> 24:57resources needed to implement
- 24:57 --> 24:59these kind of strategies
- 24:59 --> 25:01that are more complex and that may
- 25:01 --> 25:04influence and may need to influence
- 25:04 --> 25:06different levels at different factors.
- 25:06 --> 25:07And I agree with you,
- 25:07 --> 25:11I think that ultimately many things,
- 25:11 --> 25:13not all, but many things,
- 25:13 --> 25:16come down to money in terms
- 25:16 --> 25:19of who's going to fund the bus,
- 25:19 --> 25:21who's going to hire
- 25:21 --> 25:23more health care workers.
- 25:23 --> 25:25And I think, you know,
- 25:25 --> 25:27when we think about low to
- 25:27 --> 25:28middle income countries,
- 25:28 --> 25:31these countries developmentally are
- 25:33 --> 25:37just at the beginning
- 25:37 --> 25:40of their trajectory in terms
- 25:40 --> 25:43of national development and
- 25:43 --> 25:46oftentimes don't have a very strong
- 25:46 --> 25:49or stable GDP oftentimes
- 25:49 --> 25:52have governments that have
- 25:52 --> 25:55varying degrees of corruption.
- 25:55 --> 25:59And so trying to obtain funding
- 25:59 --> 26:03that is sustainable and that
- 26:03 --> 26:07can be funneled into healthcare
- 26:07 --> 26:09it is really difficult.
- 26:09 --> 26:11Now one of
- 26:11 --> 26:13the other things that you had mentioned
- 26:13 --> 26:17before the break is that you also have
- 26:17 --> 26:20been involved in work in HIV and
- 26:20 --> 26:22we know that around the world
- 26:22 --> 26:25we've actually seen a great deal
- 26:25 --> 26:29of progress in terms of HIV and
- 26:29 --> 26:33its control in large part mediated
- 26:33 --> 26:36by philanthropy and
- 26:36 --> 26:37the millennial development
- 26:37 --> 26:40goals of really reducing HIV,
- 26:40 --> 26:42malaria and TB.
- 26:42 --> 26:44And so the next question is,
- 26:44 --> 26:47is this one strategy that you may have
- 26:47 --> 26:51looked at or thought about in terms of
- 26:51 --> 26:56increasing infrastructure.
- 26:56 --> 26:58Getting out into cancer,
- 26:58 --> 27:01whether it's cervical cancer or others,
- 27:01 --> 27:04is building upon the infrastructure
- 27:04 --> 27:07that might already exist in terms of HIV.
- 27:07 --> 27:10And how would that work,
- 27:10 --> 27:12how does that look and is that something
- 27:12 --> 27:14that various countries are trying?
- 27:16 --> 27:17Yeah, very good point,
- 27:17 --> 27:19very good question.
- 27:19 --> 27:22And the integration of
- 27:22 --> 27:25services is something that
- 27:25 --> 27:26depends on the kind of services.
- 27:26 --> 27:27But integration specifically with
- 27:27 --> 27:31HIV services is a kind of a strategy
- 27:31 --> 27:33that is being used for different
- 27:33 --> 27:35purposes in different countries but
- 27:35 --> 27:38especially those
- 27:38 --> 27:41in which there are
- 27:41 --> 27:44high incidence or prevalence of HIV
- 27:44 --> 27:46especially in subsaharan Africa.
- 27:46 --> 27:50And there are efforts to integrate
- 27:50 --> 27:53chronic disease as well as cervical
- 27:53 --> 27:56cancer and cancer for other
- 27:56 --> 28:00care for other cancers into the
- 28:00 --> 28:02HIV programs since those have in
- 28:02 --> 28:04some way already figured out and
- 28:04 --> 28:06have the personnel have the support
- 28:06 --> 28:08or the infrastructure,
- 28:08 --> 28:10although they still have challenges
- 28:10 --> 28:12and barriers to implementing the
- 28:12 --> 28:13evidence based interventions.
- 28:13 --> 28:14But yeah,
- 28:14 --> 28:16there are some efforts that are being made to
- 28:16 --> 28:19try to integrate hypertension and
- 28:19 --> 28:21chronic disease, for example, management,
- 28:21 --> 28:24into HIV services as well as
- 28:24 --> 28:25cancer control services,
- 28:25 --> 28:27especially in the case of cervical
- 28:27 --> 28:29cancer, a cancer that is
- 28:29 --> 28:31elevated among those with HIV.
