IntroductionPolice officers are at an elevated risk for needle-stick injuries (NSI), which pose a serious and costly occupational health risk for HIV and viral hepatitis. However, research on NSIs among police officers is limited, especially in low- and middle-income countries. Despite the legality of syringe possession in Mexico, half of people who inject drugs (PWID) in Tijuana report extrajudicial syringe-related arrests and confiscation by police, which has been associated with needle-sharing and HIV infection. We assessed the prevalence and correlates of NSIs among Tijuana police officers to inform efforts to improve occupational safety and simultaneously reduce HIV risks among police and PWID.MethodsTijuana's Department of Municipal Public Safety (SSPM) is among Mexico's largest. Our binational, multi-sectoral team analyzed de-identified data from SSPM's 2014 anonymous self-administered occupational health survey. The prevalence of NSI and syringe disposal practices was determined. Logistic regression with robust variance estimation via generalized estimating equations identified factors associated with ever having an occupational NSI.ResultsApproximately one-quarter of the Tijuana police force was given the occupational health survey (N=503). Respondents were predominantly male (86.5%) and ≤35 years old (42.6%). Nearly one in six officers reported ever having a NSI while working at SSPM (15.3%), of whom 14.3% reported a NSI within the past year. Most participants reported encountering needles/syringes while on duty (n=473, 94%); factors independently associated with elevated odds of NSIs included frequently finding syringes that contain drugs (adjusted odds ratio (AOR): 2.98; 95% confidence interval (CI): 1.56–5.67) and breaking used needles (AOR: 2.25; 95% CI: 1.29–3.91), while protective factors included being willing to contact emergency services in case of NSIs (AOR: 0.39; 95% CI: 0.22–0.69), and wearing needle-stick resistant gloves (AOR: 0.43; 95% CI: 0.19–0.91).ConclusionsTijuana police face an elevated and unaddressed occupational NSI burden associated with unsafe syringe-handling practices, exposing them to substantial risk of HIV and other blood-borne infections. These findings spurred the development and tailoring of training to reduce NSI by modifying officer knowledge, attitudes and enforcement practices (e.g. syringe confiscation) – factors that also impact HIV transmission among PWID and other members of the community.

Background and Objectives: Policing practices do not reflect recent decriminalization of drug possession in Mexico. We assessed knowledge of cannabis law as part of a police education program (PEP) post-drug law reform in Tijuana. Methods: Officers took pre-/post-PEP surveys; random subsample (n = 759) received follow-up assessments. Longitudinal logistic regression (pre-, post-, 3-months post-PEP) measured knowledge of cannabis law. Results: PEP increased conceptual knowledge of cannabis law from baseline to post-training (AOR = 56.1, CI: 41.0–76.8) and 3 months post-PEP (AOR = 11.3, CI: 9.0–14.2). Conclusion and Scientific Significance: PEPs improve police knowledge of cannabis law. Reforms should be bundled with PEPs to improve policy implementation. (Am J Addict 2018;27:608–611).
