This study describes postabortion complication severity and associated factors in Kenya. A nationally representative sample of 326 health facilities was included in the survey. Data were collected from 2,625 women presenting with abortion complications.The study concludes that moderate and severe postabortion complications are common in Kenya and a sizeable proportion of these are not properly managed. Factors such as delay in seeking care, interference with pregnancy, and unwanted pregnancies are important determinants of complication severity and fortunately these are amenable to targeted interventions.
