RESUMO
We compared quality improvement (QI) interventions for prevention of mother-to-child transmission in a private hospital and a government hospital (GH). From November 2013 to October 2016, data were extracted retrospectively for HIV-positive mothers and HIV-exposed infants. The overall number of mother-baby pairs (MBPs) was significantly (P < .001) higher at the GH (mean = 294, standard deviation [SD] = 180) than the private hospital (mean = 72, SD = 27). There was a significantly higher number of MBPs receiving care (P < .001) and routine services (P < .001) at the GH. The proportion of MBPs retained in care (P < .001) and receiving the routine service package (P < .001) was significantly higher at the private hospital. Overtime, indicators at the private hospital peaked significantly in year 2 and reduced moderately in the final year. The trend for the GH showed gradual but nonsignificant improvement in 2 indicators. QI showed positive results in the private hospital. If systematically applied in GHs, QI can support improved services for larger patient volumes.
