To quantify driving times, distances, and costs from population-weighted centroids of all census tracts in the US to the nearest syringe services program (SSP) to better estimate the overall burden in accessing SSPs and its implications for public health.
Key Findings:
Access to SSPs is uneven across the US, with significant variation in travel burden.
Mean driving time to the nearest SSP was 16 minutes in Alabama, with distances ranging from 0.69 to 6.03 miles across 17 metropolitan areas.
A national study found a median distance of 37 miles from zip code centroids to the nearest SSP.
The cost of accessing SSPs varies significantly, impacting overall accessibility.
Interpretation:
The study highlights the structural and individual burdens imposed by limited access to SSPs, emphasizing the need for improved accessibility and policy changes to mitigate overdose and related health issues.
Limitations:
The study did not involve human participants, thus exempt from IRB approval.
Focus on travel burden may overlook other barriers to accessing SSPs.
Potential biases in data sources may affect the findings.
Conclusion:
Improving access to SSPs is crucial for addressing the overdose crisis and related health issues, necessitating policy changes and infrastructure improvements.
