Burden of disease studies supporting policymaking in the European Union: a systematic review.

Abstract

Burden of disease (BoD) studies quantify the health impact of diseases and risk factors, which can support policymaking, particularly in the European Union (EU). This study aims to systematically analyse BoD studies, which address EU public policies to contribute to the understanding of its policy uptake. A systematic search of six electronic databases and two grey-literature registries was carried out for articles published between 1990 and 2023. The thematic area, type of legislation and the respective policymaking stage were extracted. A textual analysis of the discussion was conducted to assess the inclusion of specific EU policy implications. Overton was used to detect citations in policy documents. Out of the 2054 records screened, 83 were included. Most studies employed secondary data, with 37 utilizing GBD data. Disability-adjusted life year was present in most of the studies (n = 53). The most common type of the EU legislation mentioned was the directive (n = 47), and the most frequent topic was environment (n = 34). Policy implications for EU laws were discussed in most papers (n = 46, 55.4%), with only 8 conducting evaluation of EU policies. Forty-two articles have been cited at the EU-level, in a total of 86 EU policies. Despite increasing efforts in integrating EU legislation impact within BoD studies, these results denote a low consideration of the legal and policy changes. Greater efforts in directing research towards policy effectiveness evaluation might increase their uptake in EU policies.
