Younsook Lim and colleagues describe the Rwanda Learning Collaborative on Child Health, which aimed to improve and extend the impact of prevention of mother-to-child transmission of HIV/AIDS.
Comprehensive prevention of mother-to-child transmission of HIV/AIDS (PMTCT) care requires following mothers and infants longitudinally to ensure quality care is delivered.
Targeted disease-specific programs can be designed to have an impact on related nontargeted services to increase the health value delivered to families.
Quality improvement methods can be effective tools for engaging local health workers and targeting investment of limited resources to maximize improvement of services.
A learning collaborative approach is one method that can garner cooperation between nongovernmental organizations and governments to improve coordination of services and strengthen health systems.
A recent World Health Organization (WHO) report found a complex array of positive and negative impacts of global health initiatives (GHIs) on existing health systems
The 2006 WHO treatment guidelines for PMTCT emphasize that efforts to decrease transmission must be based on the delivery of broad maternal and child health services. Such approaches can reduce transmission rates to less than 2%
In recent years, the percentage of HIV-positive pregnant women living in low- and middle-income countries who are receiving antiretroviral medication to prevent transmission to their infants has increased: from 10% in 2004 to 45% in 2008
The Rwanda Learning Collaborative on Child Health (RLC) was conceived as a service delivery component of the Joint Learning Initiative on Children and HIV/AIDS (JLICA). The project sought to increase access to and the quality of PMTCT services in the Eastern Province of Rwanda using a learning collaborative model. This method focuses on peer-to-peer learning through periodic “learning sessions,” meetings at which participants convene to discuss improvement of selected indicators. The approach allows for multiple improvement ideas to be simultaneously tested and evaluated
Although using the learning collaborative model to spread best clinical practices in developed countries has had mixed results
The RLC employed all key elements of a learning collaborative. Four learning sessions were held between June 2007 and April 2009; these were one-day meetings where health center participants and experts from TRAC and NGO partners reviewed health center progress and technical information. “Action periods” occurred between learning sessions. During these periods, health center staff tested improvement ideas, which were evaluated through the use of standard time plots charting an indicator (for example, number of women receiving antenatal care) against months. When testing ideas, health center staff applied a quality improvement approach known as a plan-do-study-act (PDSA) cycle that focuses on executing and evaluating improvement ideas on a small scale by a team of health providers. The approach has a specific structure: planning an improvement idea, testing it (“do”), studying the results, and acting to make additional changes based on the results
Rwanda is moving toward a decentralized health care system that provides HIV/AIDS and PMTCT services at the health center level. The country has nationalized health insurance, a structured community health worker (CHW) system, and its government oversees all NGO activities
To facilitate communication between health centers, a field team of two Rwandan professionals trained in the learning collaborative method provided technical support. This team visited health centers bi-weekly to assist with the development, implementation, and assessment of PDSA cycles, and collected data on selected indicators. The field team received logistical and administrative support from the François-Xavier Bagnoud Center for Health and Human Rights at Harvard University.
Experts from the JLICA and TRAC convened in Kigali in March 2007 to conduct a value chain analysis of PMTCT care (see
All 17 health centers carried out improvement activities in target areas for the duration of the project. Thirty-four unique ideas covering all areas of improvement were tested. Increasing health center attendance through provision of material incentives, expanding access to services through outreach sites, and strengthening links between patients and health care providers through CHWs were among the many ideas health centers explored. Although most health centers reported notable improvements during the project, these numbers are not amenable to standard tests of statistical significance because of the underlying assumptions inherent in the statistical methods used in quality improvement.
Six months prior to the RLC, participating health centers averaged 20% (
At the outset of the project, only four health centers used a devoted registry to track women through PMTCT care. By the end of the project, 11 health centers used a separate PMTCT registry for tracking HIV-positive women and 15 reported 95% of HIV-positive pregnant women receiving PMTCT services (
National data from 2007 indicate that 87% of women attending their first ANC visit learned their HIV status
Rwanda's national policy to reduce postnatal HIV transmission follows WHO guidelines, which recommend that HIV-positive mothers either use infant formula if acceptable, feasible, affordable, sustainable, and safe (AFASS), or exclusively breastfeed and wean at 6 mo
Eleven health centers initially offered co-trimoxazole prophylaxis. Six health centers reported that up to half of children identified to receive prophylaxis had not returned to the clinic for several months. By the last 8 mo of the project, 15 health centers offered co-trimoxazole prophylaxis. At ten health centers reporting consistent monthly data, an average of 98% of HIV-exposed infants received prophylaxis (
The largest obstacle reported was traveling long distances to health centers in order to receive the medication. In one testing cycle, co-trimoxazole was given to HIV-exposed infants on the same day each month, coupled with other services such as feeding counseling, and coinciding with market days when women were likely to be near the health center. The first health center to test this idea reported an increase in coverage from 40% to 100%. This outcome was shared at the second learning session and the intervention was implemented at ten additional health centers.
Monitoring ECD was considered an important component of comprehensive PMTCT care. However, the field team observed that ECD screening at health centers consisted of measuring only height and weight. The RLC developed an ECD tool using “Care for Development” guidelines from the WHO's Integrated Management of Childhood Illness to increase implementation of comprehensive ECD monitoring in the community. Training on ECD and use of the ECD tool was organized for 34 nurses from all health centers. These nurses in turn trained CHWs at their respective health centers on how to use the tool during home visits to counsel caregivers on ECD. Across ten health centers, nurses reported that 962 CHWs received training by the end of the project.
From July to November 2007, vaccination coverage averaged 83%. Vaccination completion increased to an average of 90% during the last 8 mo of the project by increasing the number of outreach vaccination sites and having CHWs visit children who missed appointments. Health centers were able to increase bed net distribution from 80% to 94% in the first 10 mo of the project by improving distribution of bed nets to outreach sites until a nationwide stock out of bed nets.
The experience of the RLC suggests that the learning collaborative model can have a positive impact not only on the quality of targeted areas of care, but also on the capacity of health centers to more effectively deliver nontargeted services. This systems-based approach was useful in encouraging problem solving in a local context, assisting in the determination of where resources were needed, and encouraging demand from those who utilize services.
A questionnaire at the final learning session was completed by 28 out of 29 learning session attendees from participating health centers. Among those responding, 71% found the project to be different in significant ways from others conducted by the MOH or other NGOs; 91% found using time plots to be helpful with 82% believing they would continue to use them; and 77% found using PDSA cycles to be a helpful tool in making improvements, with 70% believing they would continue to use them. Investments in human resources such as this, which empower staff to take initiative in identifying the need for improvements and to act to remedy them, represent a worthwhile development of local capacity.
The supplemental funding of health center budgets by the RLC was relatively small. Cloth wraps for women cost FRW1,500 (US$2.64) each, a CHW monthly stipend was FRW2,500 (US$4.40), and a month of supplemental food for weaning was FRW10,500 (US$18.50) per infant. These small investments were often followed by substantial improvements, suggesting that quality improvement projects may be effective tools not only for improving service delivery but for leveraging funding.
Addressing barriers at the local level improved health services for all women regardless of HIV status. For example, although not an explicit focus of the project, women delivering at participating health centers increased from 56% in 2007 to 72% in 2008, which is higher than the 2008 national average of 45%
Through the RLC, local health center staff viewed the improvement of immunization services, bed net distribution, and early childhood screening, which are not traditionally included in programs targeting PMTCT, as synergistic components of delivering care to affected women and children rather than as competing programs.
Comprehensive PMTCT services involve multiple systems of care. Coordination between several governmental agencies and supporting partners at health centers at times posed obstacles to a unified approach to PMTCT. For example, in an effort to train community health workers on reproductive health as part of raising community awareness, the RLC had to obtain approval from: the Community Health Desk, the Maternal and Child Health Unit, TRAC, the health centers' supporting NGOs, and each health center. The RLC was able to work within this complex system of stakeholders largely owing to the MOH's active engagement. Recommendations made by health center staff or the support team that required substantive change to current procedures were communicated to TRAC and the MOH for support. Thus the Rwandan government was invaluable in providing leadership and fostering cooperation.
While learning collaborative methods such as the RLC offer an effective structure for disseminating best practices and sharing solutions at the grass-roots level, this project required significant external technical support to make effective improvements. In other settings, this requirement may impose a barrier to the outcomes that can be achieved by this approach. The addition of financial resources to overcome specific barriers also poses challenges in resource-poor countries where governments and NGOs may be working with limited budgets.
As the influence of global health initiatives (GHIs) continues to grow, the architects of programs targeting specific diseases or areas of care can commit themselves to considering the impact their interventions can have on health systems and outcomes beyond their immediate focus. Quality improvement approaches could be employed as effective organizing tools under active government guidance with the cooperation of NGOs to target investment of resources and strengthen health systems.
