  • To start off, I want to make sure that we’re all thinking about PMTCT in the same way. PMTCT is a package of care services that starts during pregnancy and lasts all the way until the exposed infant has a final infection status and is discharged from the PMTCT program. This graphic shows all of the biomedical interventions that need to happen at each time period.
  • What are the take away messages from this PMTCT Care spectrum?We need to shift our thinking, reconceptualize what we mean by PMTCT.
  • Let’s review..What are some of the apss activities which would support adherence to these activities? Ask audience, give examples.Antepartum activities: Adherence counseling on PMTCT prophylaxis, targeted counseling for GA, support groups, peer educators, tracking and tracing plan that worksIntrapartum activities: Counseling during pregnancy on birth plan (where and how), apss support in labor ward for immediate postpartum support
  • Postpartum:For mom-support groups, especially around infant feeding and EID results, systems to ensure her engagement with CTC for her own healthInfant: systems that ensure follow-up in missed appts.
  • It is necessary that adherence and psychosocial support activities endure over a long period of time after delivery, not just in the immediate pp period
  • Now that we’re thinking about the PMTCT as this whole spectrum, a “package of care”, I’d like to hear your thoughts on adherence to this package. In looking at this spectrum, where do you think the biggest pt losses (in terms of ltfu)occur?One of the reasons why there are still so many children who acquire HIV from MTCT is because there has been a failure to implement this entire spectrum of interventions. But this spectrum does not reflect the psychosocial activities which must run parallel to the biomedical interventions in order to support the mother and her family to adhere to the entire package of PMTCT care and treatment.
  • There will be a more focused discussion on this topic during the concurrent sessions, but are there ideas for what would constitute adherence to PMTCT care? Care=appointments Adherence to care would mean that every woman tested HIV+ returns for all of the necessary follow-up visits.PMTCT treatment? Treatment=the appropriate prophylaxis or treatment as determined eligible for both mom and baby. Adherence to treatment would mean that every woman who initiates AZT prophylaxis or HAART during pregnancy is adherent to her meds, and that every infant given AZT syrup and CTX is given his/her meds appropriately.
  • In order to start thinking about what kinds of activities we need to implement in order to increase adherence, we need to consider the barriers.
  • (I’m going to insert the citations at the bottom)What are some of the barriers to adherence to PMTCT care (visits) that you have experienced in your countries?There is no data that I could find on barriers to follow-up visits during the postpartum period for HIV+ moms.
  • It is important to consider as well, that approximately 20% of PMTCT mothers should be eligible for treatment for their own health, so most if not all of the treatment barriers which we think about for adults on treatment would apply here as well.
  • Of the number estimated to be pregnant women living with HIV only 45% received any antiretrovirals for PMTCT and only 30% of estimated number of exposed infants were reported to have received treatment in 2008
  • Over time, the proportion of women getting a single antiretroviral for PMTCT is decreasing. This points to an increase in the proportion of women getting combination regmines, which means that we need to start thinking about how to keep women in care over time.
  • This shows the proportion of different prophylaxis regimens for PMTCT in ICAP countries.
  • This slide shows the proportion of HIV+ pregnant women with CD4 test results among 224 PMTCT sites reporting CD4 results in the past quarter as compared to the mean average over the previous year.If we include receiving CD4 test result in order to determine HAART eligibility as one of the activities on the spectrum which need to be done in our PMTCT package, then we can see that we are not achieving this. Far fewer than 100% of HIV+ pregnant women are getting their CD4 test results. Consider that ICAP has more than 600 PMTCT sites, and of those, only these 224 report having any CD4 test results on a pregnant woman.
  • Elaine: Tell me what you think of this slide. I got these #s from the URS for the past year (from last quarter back one year). I want to show a slide with many of the elements of the spectrum which are URS indicators in order to make the point that although it looks like we can follow a trend of adherence, really we cant. But if you think the #s look funny still, I can try and think of another way to do it.I CAN’T SPEAK TO THIS SLIDE AS I DON’T KNOW HOW THEY GOT THE DATA FOR MOST OF THE INDICATORS. I THINK TOO MANY WOMEN ARE IDENTIFIED HERE AS HAVING HAD A CD4 , ETC BUT YOU COULD SHOW IT AND QUALIFY THAT THE DATA ARE TAKEN FROM DIFFERENT PLACES AND ARE ILLUSTRATIVE.
  • Let’s look at how some studies have measured adherence in PMTCT:The PEARL study did an evaluation of adherence to sd-NVP, the minimum intervention for PMTCT. At each step along the cascade-with documentation and programmatic activities-women were lost and ultimately the intervention was not adhered to and only 49% of mother-infant couples received NVP.
  • A simple data collection instrument to abstract routinely collected mother and infant care information from facility registers (ANC and ARCC)The tool consisted of a single sheet, divided into mother and infact sectionAll variables registered ( patient charts) included routine antenatal care components as well as HIV care and treatment, partner testing and maternal post partum follow up
  • I deleted the data from Maputo. We can discuss about it before the presentation.55% of the mothers registered their babies at the infant clinic: show good linkages between services and good adherence to follow up.8 babies/11 (72%) had documented 6 weeks infant outcomes. 7/8 ( 87.5%) had PCR negative result and 1/8 (12.5%) had PCR result positive
  • So to review, how can our programs measure PMTCT adherence….
  • Best ways to measure adherence require going to the registers…and then feeding back information to the sites so that they can apply the information to their activities to improve
  • The toolsreflect this new approach to PMTCT that we’ve been exploring. The mother-infant pair tool looks one mom and her baby over the time that they should be receiving care and treatment and looks at adherence to the overall package for the mom-baby couple.And the other tools evaluate adherence to specific parts of the pmtct spectrum-prophylaxis for mom and baby, and linkages with the care and treatment clinics for both mom and baby. These tools go into more detail and can help identify at what point in, for example, prophylaxis provision in ANC, or at what point in the referral to CTC for an HIV+ infant, are we losing patients.BUT the tools only tell us how we are doing. They don’t tell us how we can achieve improved adherence.
  • In order to think about how we can actually improve adherence, let’s first review what is new and different a bout this new way of thinking about PMTCT?
  • We’ve encountered many of these same issues in the ART roll-out, and can apply many of the lessons learned from our experiences there to PMTCT.

      What do we mean when we talk about PMTCT? What about PMTCT adherence?
      What are some barriers to adherence in PMTCT programs?
      How can we measure PMTCT adherence?
      What activities and systems can help strengthen PMTCT adherence?
    • 3. PMTCT Care Spectrum
    • 4. MTCT occurs during pregnancy, delivery and throughout the duration of breast feeding
      Early Postpartum
      (0-1 mo)
      Early Antenatal
      (<28 wks)
      Late Postpartum
      Labor and
      Up to 40% of transmissions
      can occur during breast feeding
      Late Antenatal
      (28 wks to labor)
      1-6 mos
      6-24 mos
      Proportion of infections
    • 5. The possibility of mother-to-child transmission does not end at delivery, so our prevention activities must not end there!
    • 6. Take home message: Re-conceptualize PMTCT
      PMTCT does not end at delivery
      There are 2 people involved (mother-child)
      Activities occur in different service areas (ANC, Maternity, Exposed Infant Clinic, Care and Treatment Clinic)

    • 10. PMTCT Care Spectrum: Not yet complete
    • 11. Food for thought: What is PMTCT adherence?
      If this whole spectrum of activities is the Package of PMTCT, then how would we define adherence to PMTCT?
      To PMTCT Care
      To PMTCT Treatment
    • 12. Special barriers to consider for PMTCT
      Review of the existing literature on specific barriers to adherence for HIV + pregnant and post-partum women and their infants
    • 13. Barriers to PMTCT Care adherence(PMTCT visits after positive test result)
      Fear of stigma and discrimination
      Lack of knowledge and understanding of PMTCT interventions
      Focus only on the infant, not on the mother
      Lack of spousal or family support
      Long wait times at ANC
      Associated costs
      Negative interactions with Health Care Workers

    • 17. Percentage distribution of ART regimens for pregnant women
      Towards Universal Access – Scaling up priority HIV/AIDS interventions in the health sector. WHO/UNAIDS/UNICEF, 10.2009
    • 18. PMTCT prophylaxis and ART regimens among HIV+ women at ANC, ICAP, Jul 07 – Jun 09
    • 19. Proportion of HIV+ pregnant women with CD4 test results among 224 PMTCT sites, ICAP, April 2008-June 2009
      Mean: average proportion of HIV+ pregnant women with documented CD4 result from April 2008-March 2009 vs. latest reporting, Apr-Jun 2009
    • 20. Can we use routinely collected data to measure PMTCT adherence?
    • 21. Select PMTCT indicators from the URS Jun 2008-July 2009
    • 22. No. They only give us a general sense.
      These data do not tell us about one woman’s receipt of or adherence to care or treatment over time.
      They tell us how many individuals were documented to have received each separate intervention in the reporting period
    • 23. The Pearl Study: NVP coverage cascade in HIV+ Women and their infants
      Number of women
      Coetzee D et al. IAS, 2009, Abs. WeLBD101

      ICAP Rwanda PMTCT Program Manager
      ICAP Mozambique PMTCT Technical Advisor
    • 26. Adherence and linkages workshop: Kgl Oct 09Using the routinely collected data from the URS to show the rates of HEI enrollment into HEI follow-up
      Canisious Musoni- PMTCT program manager
    • 27. Introduction
      Under PMTCT program :
      • ANC- C&T, CD4, prophylaxis, Linkages
      • 28. Maternity- C&T, nutrition advise, registration of HEI and appointment system
      • 29. HEI follow –up- Prophylaxis, EID , nutrition & growth monitoring
      • 30. All 32 PMCT sites do offer EID services
      • 31. Service integration : eg, FP
      • 32. Nutrition services- weaning food program
      • 33. Linkages and referral system- on site, away sites
    • HEI follow up in Rwanda
      • HEI follow-up occurs at health facilities with the following package offered:
      • 34. After delivery: ARV prophylaxis (Sd-NVP at birth and AZT for 4 weeks) is given.
      • 35. Registration of HEI and appointment at 6 weeks for CTP and 1st DNA testing
      • 36. Monthly appointments for growth monitoring, CPT and further DNA and serology tests
      • 37. At community level:
      • 38. Community is sensitized for facility delivery and post partum care
      • 39. Peer Educators work with C H W/ leaders to remind women and children obey appointment schedules . Social events are usually used as forum to pass health messages
      • 40. Activities at every site:
      • 41. Growth monitoring assessment
      • 42. Nutritional assessment and psychosocial evaluation of the mother.
      • 43. CPT provision , biological assessment (tests) depending on the age
      • 44. Documentation of new information
      • 45. Appointment for next visit
    • HIE enrolment follow-up
    • 46. Data comments
      Not easy to track cohort adherence information with URS data source
      The number of the infants is usually greater than the number of the women who delivered due to :
      • Time lag between births and qualifying for 1st CTP and DBS with respect to sequential reporting periods
      • 47. In-transfers from other HCs/outside catchment areas
      • 48. The CPT Indicator not being good as it reports all infants accessing CPT from 4 weeks and above.
    • What facilitates HIE follow up?
      Pre and post partum counselling messages regarding prophylaxis
      Improved functioning appointment system –after birth
      Established follow up mechanism both at the health and community
      Synergistic working relationship btn the CHW and PE help remind/refer clients to seek healthcare in time.
      At HC, PE facilitate client orientation , reinforce adherence messages and facilitated support group formation
      Govt buy in and engagement
    • 49. Need for improvement
      Harmonization of appointment schedules (eg vaccination and HIV follow up)
      Re - enforcement of prophylaxis , EID counselling messages right way from ANC till delivery especially for discordant couples
      Having an established M&E system that works with the rest of the units. In Rwanda, from e-data base, the data manager can easily retrieve the number of those missing their appointments. Then, worker or nurse can send PE out bring them back.
      Ownership of the program by health care facilities
