A regional audit system for stillbirth: a way to better understand the phenomenon.

BACKGROUND: Implementation of high-quality national audits for perinatal mortality are needed to improve the registration of all perinatal deaths and the identification of the causes of death. This study aims to evaluate the implementation of a Regional Audit System for Stillbirth in Emilia-Romagna Region, Italy. METHODS: For each stillbirth (≥ 22 weeks of gestation, ≥ 500 g) occurred between January 1, 2014 to December 1, 2016 (n = 332), the same diagnostic workup was performed and a clinical record with data about mother and stillborn was completed. Every case was discussed in a multidisciplinary local audit to assess both the cause of death (ReCoDe classification) and the quality of care. Data were reviewed by the Regional Audit Group. Stillbirth rates, causes of death and the quality of care were established for each case. RESULTS: Total stillbirth rate was 3.09 per 1000 births (332/107,528). Late stillbirth rate was 2.3 per 1000 (251/107,087). Sixteen stillbirths were not registered by the Regional Birth Register. The most prevalent cause of death was placental disorder (33.3%), followed by fetal (17.6%), cord (14.2%) and maternal disorders (7.6%). Unexplained cases were 14%. Compared to local audits, the regional group attributed different causes of death in 17% of cases. At multivariate analysis, infections were associated with early stillbirths (OR 3.38, CI95% 1.62-7.03) and intrapartum cases (OR 6.64, CI95% 2.61-17.02). Placental disorders were related to growth restriction (OR 1.89, CI95% 1.06-3.36) and were more frequent before term (OR 1.86, CI95% 1.11-3.15). Stillbirths judged possibly/probably preventable with a different management (10.9%) occurred more frequently in non-Italian women and were mainly related to maternal disorders (OR 6.64, CI95% 2.61-17.02). CONCLUSIONS: Regional Audit System for Stillbirth improves the registration of stillbirth and allows to define the causes of death. Moreover, sub-optimal care was recognized, allowing to identify populations which could benefit from preventive measures.

[Using hospital discharge records, birth certificates and a birth defects registry for epidemiological and public health purposes: experience in Emilia-Romagna region (northern Italy)]. / Utilizzo delle schede di dimissione ospedaliera, dei certificati di nascita e del registro delle malformazioni congenite a scopi epidemiologici e di sanità pubblica: esperienza in Emilia-Romagna.

OBJECTIVES: implementation and validation of a methodology to link and integrate hospital discharge record (SDO), birth certificate (CeDAP) and the population-based registry of congenital malformations of the Emilia-Romagna Region (IMER). An algorithm has been developed to link registry data and administrative data through the use of indirect patient identifiers in order to exploit the strengths of the different data sources and to expand the pool of existing data available for the analysis. DESIGN: use of IMER Registry, birth certificates and hospital discharge records to assess and diagnose congenital malformations; these data sources vary in terms of availability and accuracy. SETTING AND PARTICIPANTS: data from IMER Registry, SDO and CeDAP for year 2009 have been used. RESULTS: the main results of the study are: 1. a perfect monitoring system does not exist, the algorithm proposed enabled the integration of three different sources and the evaluation of the capacity to identify different anomalies to be capitalized on; 2. the high number of false positives in audit reporting in 4 hospitals underlines the importance of the contribution of clinical experts in the review of the case to exclude coding errors, clarify unspecific diagnostic categories and identify syndromes; 3. the IMER Registry with over 30 years of experience has been the catalyst for this work by integrating clinical skills in the registry with the public health expertise of other professionals involved in information flows; 4. in the absence of a single comprehensive source of data collection, the advantage of the integration of the information collected from multiple sources is confirmed. CONCLUSION: birth defects surveillance programmes are critical resources that can provide fundamental information to take sound decisions in healthcare planning and for environmental epidemiology studies. This experience, whilst not mechanically transferable to other areas and circumstances, is a model for the future clinical and epidemiological management of congenital anomalies.
