Recommendations for preventing stillbirth: a regional population-based study in Japan during 2007-2011.
The perinatal mortality rate in Japan has recently been at the lowest level in the world. However, the perinatal mortality rate of Shiga prefecture has been continuously higher than the Japanese average. The reason for this has not yet been explained. The perinatal mortality rate comprises both stillbirths and neonatal deaths. As stillbirths were almost double neonatal deaths, we focused on the stillbirths to determine how they might be prevented. All of the stillbirth certificates in Shiga Prefecture during 2007-2011 were inspected. On the basis of that information, we designed the original questionnaire and sent it to each obstetrician submitting a death certificate to obtain further information associated with the stillbirth. Reviewing retrospectively returned questionnaires by a peer-review team, we evaluated the possibility of preventing stillbirth along with recommendations for prevention. There were 252 stillbirths among 66,682 deliveries in Shiga during this period. We were able to analyze 188 stillbirths (75%). The audit conference judged that 47 cases of them (25%) were determined to have had some possibility of prevention with seven cases (4%) having strong possibility. We identified major causes of preventable stillbirths, including substandard obstetrical management, delayed referral of high-risk women from primary obstetrical clinics to higher perinatal centers, and delayed visits of pregnant women with decreased fetal movements to clinics or hospitals. Based on the results of this study, we conclude that education for pregnant women is required as well as the necessity of improving obstetric care to prevent stillbirths.
