The Effect of a Continuous Quality Improvement Intervention on Retention-In-Care at 6 Months Postpartum in a PMTCT Program in Northern Nigeria: Results of a Cluster Randomized Controlled Study.

BACKGROUND: Retention in care is critical for improving HIV-infected maternal outcomes and reducing vertical transmission. Health systems' interventions such as continuous quality improvement (CQI) may support health services to address factors that affect the delivery of HIV-related care and thereby influence rates of retention-in-care. METHODOLOGY: We evaluated the effect of a CQI intervention on retention-in-care at 6 months postpartum of pregnant women and mothers living with HIV who had been started on lifelong antiretroviral treatment. Thirty-two health care facilities were randomized to either implement the intervention or not. We considered women fully retained in care when they attended the 6-month postpartum visit and did not miss any previous scheduled visit by more than 30 days. RESULTS: Five hundred eleven women living with HIV attending antenatal clinics at 26 facilities were included in the analysis. Median age at enrolment was 27 years and gestational age was 20 weeks. Seventy-one percent of women were seen at 6-month postpartum irrespective of missing any scheduled visit. However, 43% of women were fully retained at 6-month postpartum and did not miss any scheduled visit based on our stringent study definition of retention. There was no significant difference in retention at 6 months between the intervention and control arms [44% vs. 41%, relative risk: 1.08; 95% confidence interval (CI): 0.78 to 1.49]. Initiation of ARV prophylaxis among infants within 72 hours was not different by study arm (66.0% vs. 74.7%, relative risk = 0.95; 95% CI: 0.84 to 1.07) but rates of early infant testing at 4-6 weeks were higher in intervention sites (48.8% vs. 25.3%, adjusted relative risk: 1.76; 95% CI: 1.27 to 2.42). CONCLUSIONS: CQI as implemented in this study did not differ across study arms in the rates of retention. Several intervention design or implementation issues or other contextual constraints may explain the absence of effect.

Using Small Tests of Change to Improve PMTCT Services in Northern Nigeria: Experiences From Implementation of a Continuous Quality Improvement and Breakthrough Series Program.

BACKGROUND: Continuous Quality Improvement (CQI) is a process where health teams systematically collect and regularly reflect on local data to inform decisions and modify local practices and so improve delivery of services. We implemented a cluster randomized trial to examine the effects of CQI interventions on Prevention of Mother-to-Child Transmission (PMTCT) services. Here, we report our experiences and challenges establishing CQI in 2 high HIV prevalence states in northern Nigeria. METHODS: Facility-based teams were trained to implement CQI activities, including structured assessments, developing change packages, and participation in periodic collaborative learning sessions. Locally evolved solutions (change ideas) were tested and measured using process data and intermediate process indicators were agreed including overall time spent accessing services, client satisfaction, and quality of data. RESULTS: Health workers actively participated in clinic activities and in the collaborative learning sessions. During the study, the mean difference in time spent accessing services during clinic visits increased by 40 minutes (SD = 93.4) in the control arm and decreased by 44 minutes (SD = 73.7) in the intervention arm. No significant difference was recorded in the mean client satisfaction assessment score by study arm. The quality of data was assessed using a standardized tool scored out of 100; compared with baseline data, quality at the end of study had improved at intervention sites by 6 points (95% CI: 2.0 to 10.1). CONCLUSIONS: Health workers were receptive to CQI process. A compendium of "change ideas" compiled into a single change package can be used to improve health care delivery.
