Assessing the validity of indicators of the quality of maternal and newborn health care in Kenya

The measurement of progress in maternal and newborn health often relies on data provided by women in surveys on the quality of care they received. The majority of these indicators, however, including the widely tracked "skilled attendance at birth" indicator, have not been validated. We assess the validity of a large set of maternal and newborn health indicators that are included or have the potential to be included in population-based surveys. We compare women's reports of care received during labor and delivery in two Kenyan hospitals prior to discharge against a reference standard of direct observations by a trained third party (n = 662). We assessed individual-level reporting accuracy by quantifying the area under the receiver operating curve (AUC) and estimated population-level accuracy using the inflation factor (IF) for each indicator with sufficient numbers for analysis. Four of 41 indicators performed well on both validation criteria (AUC>0.70 and 0.75
