Background: Afghanistan has one of the highest burdens of maternal mortality in the world, estimated at 638 deaths per 100,000 live births, Infections, obstetric hemorrhage, and unsafe abortion are the three leading causes. Contraceptive prevalence rate has fluctuated between 10–20% since 2006. The 2016 Afghanistan National Maternal and Newborn Health Quality of Care Assessment evaluated health facilities’ capacity to provide postabortion care, and skilled birth attendants’ knowledge and perceptions. Methods: Accessible public health facilities with at least five births per day on average (n = 77), a nationally representative sample of public health facilities with fewer than five births per day (n = 149), and 20 purposively selected private health facilities were assessed. Data collection methods for provision included a facility inventory and record review tool to verify drug, supply, equipment, and facility record availability, and an interview tool to collect information on skilled birth attendants’ knowledge and perceptions.Results: Most facilities had supplies, equipment, and drugs to manage postabortion care, including family planning counseling and services provision. At public facilities, 36% of skilled birth attendants asked to name essential actions to address abortion complications mentioned manual vacuum aspiration (23% at private facilities); fewer than one-quarter mentioned counseling. When asked what information should be given to postabortion clients, 73% described family planning counseling need (70% at private facilities). Seventy percent of public facilities expected to provide basic emergency obstetric and newborn care had functional manual vacuum aspiration supplies in the delivery room. More than 80% of public health facilities had male condoms, oral contraceptive pills, intrauterine devices, and injectables. Conclusions: This study provides evidence that there is room for improvement in postabortion care services provision in Afghanistan health facilities. Access to high-quality postabortion care needs additional investments to improve providers’ knowledge and practice, and availability of supplies.
