A scoping review of road traffic data systems in the Eastern Mediterranean Region

Abstract

Background: Road traffic injury is a major global health risk, however, under-reporting of road traffic crashes data and the use of different reporting systems have made it difficult to compare data across countries. Aim: To examine published and grey literature for better understanding of available health and non-health road traffic data systems in the Eastern Mediterranean Region (EMR) countries. Methods: We conducted a systematic search of databases to identify studies reporting road traffic data systems in the EMR countries between 2011 and January 2022. We also searched grey literature on the websites of government, WHO, World Bank, UNICEF, regional economic commissions and other relevant institutions. We assembled the data in Microsoft Excel and presented the counts of data sources, data types and data quality. Results: We included 84 of 2238 studies accessed in this review. One-third of the publications was from the Islamic Republic of Iran while 10% was from Pakistan. Police databases were the primary sources of data in most of the studies (79%) while hospital and death registration systems together accounted for one-quarter of the databases. The most common indicators reported in the publications were deaths (61%), crashes (48%) and injuries (35%). Only 40% of the studies disaggregated their analyses by gender and 44% by age. No papers identified permanently linked data sources, although more than a quarter of the papers reviewed used some form of modelling or data mining. Conclusion: This scoping review highlights an over-reliance on police data, poor quality traffic data systems, and multiple stakeholders collecting similar data, leading to redundancy. EMR countries need to establish robust road safety data systems to provide data for relevant policies and interventions
