Objective Injury burden is highest in low-income and middle-income countries. To reduce avoidable deaths, it is necessary to identify health system deficiencies preventing timely, quality care. We developed criteria to use verbal autopsy (VA) data to identify avoidable deaths and associated health system deficiencies.
Setting Agincourt, a rural Bushbuckridge municipality, Mpumalanga Province, South Africa.
Participants Agincourt Health and Socio-Demographic Surveillance System and healthcare providers (HCPs) from local hospitals.
Methods A literature review to explore definitions of avoidable deaths after trauma and barriers to access to care using the ‘three delays framework’ (seeking, reaching and receiving care) was performed. Based on these definitions, this study developed criteria, applicable for use with VA data, for identifying avoidable death and which of the three delays contributed to avoidable deaths. These criteria were then applied retrospectively to the VA-defined category external injury deaths (EIDs—a subset of which are trauma deaths) from 2012 to 2015. The findings were validated by external expert review. Key informant interviews (KIIs) with HCPs were performed to further explore delays to care.
Results Using VA data, avoidable death was defined with a focus on survivability, using level of consciousness at the scene and ability to seek care as indicators. Of 260 EIDs (189 trauma deaths), there were 104 (40%) avoidable EIDs and 78 (30%) avoidable trauma deaths (41% of trauma deaths). Delay in receiving care was the largest contributor to avoidable EIDs (61%) and trauma deaths (59%), followed by delay in seeking care (24% and 23%) and in reaching care (15% and 18%). KIIs revealed context-specific factors contributing to the third delay, including difficult referral systems.
Conclusions A substantial proportion of EIDs and trauma deaths were avoidable, mainly occurring due to facility-based delays in care. Interventions, including strengthening referral networks, may substantially reduce trauma deaths.

Ethics approval Ethics approval from the University of the Witwatersrand Human Research Ethics Committee to use data from the VAs in the Agincourt HDSS in secondary analyses had been previously obtained (M960720 and M110138). All analysed VA data were anonymised and no individual deceased person or respondent was identifiable from the data used and presented. Ethics approval for the independent KIIs was obtained from the University of the Witwatersrand Human Research Ethics Committee (M170269) and King’s College London Research Ethics Committee (LRU-16/17–4313). Participation in the qualitative study was voluntary and informed consent was obtained for the interview and its recording. All interviews were confidential and narratives were anonymised.
Provenance and peer review Not commissioned; externally peer reviewed.
Data sharing statement The data used for the VA analysis are available from the INDEPTH Data Repository platform at http://www.indepth-ishare.org/index.php/home.
