Evaluating perinatal health in Europe: a comparison of routine population birth data sources

Abstract Background International comparisons provide essential benchmarks for evaluating perinatal health policies, but these rely on the availability of routine national birth data. This study aimed to describe population birth data sources in Europe by their ability to provide core perinatal health indicators. Methods The Euro-Peristat Network collected routine national data on a recommended set of core indicators from 2015 to 2021 using a federated protocol based on a common data model with 17 data items. Data providers filled in an on-line questionnaire to describe the sources used in each country. We classified countries by the number of data items they provided (all 16, 15-14, <14). Results 28 out of the 31 countries that provided data responded to the survey. Routine data sources included birth certificates (14 countries), electronic medical records (EMR) from delivery hospitalizations (14 countries), direct entry by health providers (9 countries), EMR from other care providers (6 countries) and Hospital Discharge Summaries (7 countries). Completeness of population coverage was at least 98%, with 15 countries reporting 100%. These databases most often included mothers giving birth on the national territory, regardless of nationality or place of residence (19 countries). In 20 countries, routine sources were linked, including linkage between birth and death certificates (15 countries). Countries providing all 16 items (N = 8) were more likely to use EMRs from delivery hospitalizations, 88%, compared to 50% and 13% in countries with 15-14 items (N = 13) and <14 items (N = 8). Linkage was also more common in these countries, 100%, versus 75% and 50% respectively. Other data source characteristics did not differ by the ability to provide data for the common data model. Conclusions There is high diversity in the data sources used to construct perinatal health indicators in Europe. Countries using EMR with linkage to other sources had the best data availability. Key messages • There is high diversity in the data sources used to construct perinatal health indicators in Europe. • Countries using Electronic Medical Records with linkage to other sources had the best data availability.
