Concerns that sleep deprivation increases medical errors has led to increased scrutiny of the quality of medical care during night shifts. In a poster presented at the Society for Maternal Fetal Medicine in early February, Jennifer Bailit, MD, MPH from the Center for Health Care Research and Policy presented data from a study that compared complications from Caesarean sections by time of day. Data from over 18,000 Caesarean Sections at 13 medical Centers between 1999 to 2000 was reviewed. Caesarean births that occurred on the night shift did not have higher rates of complications from mother or newborn compared to births that occurred during the day. Data was adjusted for age, race, insurance status, medical conditions in the mother and the presence of preeclampsia. (posted 5/2006)poster, Jennifer L. Bailit, M.D., M.P.H.
