Scanning the horizon- environmental health indicator surveillance

Abstract Aim This work aimed to conduct a comprehensive literature review with narrative synthesis of evidence in relation to the surveillance of environmental health indicators by Public Health agencies internationally. This will strengthen the All-Hazards approach to Health Protection in Ireland. Methods The project proposal was registered on PROSPERO. Preferred Reporting Systems for Systematic Review and Meta-Analysis (PRISMA) guidelines were followed. A systematic search was conducted across five databases. In addition, relevant websites, reference lists and the grey literature were searched. Data were extracted following TIDieR-PHP guidelines. Risk of bias was considered and quality appraisal was performed using SANRA and AGREE-HS tools. A narrative synthesis of the evidence was completed. Results 12 papers were included in the final review. Four were narrative review articles describing European and worldwide initiatives and the remaining eight described a single health system. Only three papers were deemed high quality. The number of indicators monitored varied widely from one in Italy to over 400 in the USA. The most established programmes described the use of a framework such as Drivers-Pressures-States-Exposures-Effects-Actions (DPSEEA) and indicator selection criteria were applied. The papers described a variety of public health actions arising from the surveillance of environmental health indicators. The knowledge provided by this review can inform the implementation process. Establishment of a project team, and beginning with monitoring one domain is suggested. Air quality is the most frequently monitored domain internationally. The DPSEEA framework is recommended, and Briggs’ indicator selection criteria should be applied to any indicator under consideration. The system should measure both hazard and outcome measures. Finally, meaningful public health action should result from the monitoring. Key messages • Environmental health indicator surveillance is essential to all-hazards health protection. • Few public health agencies internationally are systematically monitoring environmental health outcomes.
