Gestational Pyelonephritis as an Indicator of the Quality of Ambulatory Maternal Health Care Services.

The study determines whether hospital-specific rates of gestational pyelonephritis may serve as a measure of the quality of ambulatory maternal care services in California. The rates of preterm birth and congenital neonatal infection were higher among pregnant women with pyelonephritis. Pregnant women on MediCal as payer have a higher risk because poverty may indirectly make them more physiologically vulnerable or because they receive suboptimal care.
