Built environment change for injury prevention: insights from public health professionals across public health units in Ontario, Canada.

BACKGROUND

Road-related injuries and deaths are among the most significant and avoidable public health problems in Canada. Modifications to the built environment (BE) can reduce injury rates for vulnerable road users (VRUs) and other priority populations who experience disproportionate risk. This paper highlights public health professionals' experiences working in injury prevention across Ontario public health units (PHUs) navigating barriers and facilitators to BE change. Their perspectives offer valuable insights that can support future BE change work in the Ontario public health context, thus illustrating the importance of including practitioners' voices in injury prevention research.

METHODS

Qualitative data were collected for a larger pan-Canadian study examining barriers and facilitators to BE change from the perspectives of injury prevention and transport professionals working across a variety of sectors, including public health, using key informant interviews (KI) and virtual focus groups (VFGs). Participants (n = 9) from four PHUs are included in this present study: Peel Region; York Region; Peterborough; and Ottawa. Thematic analysis was used to organize and code the data in relation to the guiding principles of the Ontario Public Health Standards (OPHS), situating our results within the broader context of public health and road-related injury prevention in Ontario.

RESULTS

Major barriers included motor vehicle prioritization and decision-making structures. Facilitators included partnerships and collaboration, champions and advocates, and access to data. Lastly, participants highlighted the important role of public health in BE change discussions and decision-making for road-related injury prevention.

CONCLUSION

Public health professionals' insights about barriers and facilitators show that some of their work aligns with the existing OPHS. Needs of local populations are clearly identified, while local data illustrating the impact of public health interventions are lacking. There are limits to PHU's capacities, as well as the capacities of communities, which can be strengthened through the work of champions and advocates. Partnerships, collaboration, and engagement are also significant facilitators to BE change, aligning with the OPHS, but PHUs need to be involved more in BE change processes in order to prioritize the safety needs of VRUs in local communities.
