[Quality of data acceptable for perinatal epidemiology surveillance: assessment of the health certificate at birth and the national obstetrics medical file. Study in three Seine-Maritime maternal wards].
Data from several sources could be used for perinatal epidemiology surveillance aimed at an assessment of regional programs such as those proposed by the Superior Committee for Public Health. A retrospective study of 561 births was conducted in three maternity wards in the French Seine Maritime department in order to evaluate the reliability of two data sources: the national obstetrics medical file and the health certificate at birth. The delivery room records were used as the gold standard. The sensitivity of the obstetrics file was better than that of the health certificate. With the obstetrics file, it was possible to identify almost all the vaginal route interventions, almost all the premature births and all the cesareans. With the health certificate, 39-58% of the vaginal route interventions, 61% of the premature births and 61-72% of the cesareans performed in the three wards studied were identified. The quality of data in the obstetrics file appears to be better than that in the health certificate but only concerns 40% of births in the geographical area studied. Inversely, the health certificate is theoretically delivered for all births (actually delivered for 93%). Integrating these two information systems could be an optimum solution.
