How effective is drug testing as a workplace safety strategy? A systematic review of the evidence

摘要: The growing prevalence of workplace drug testing and the narrow scope previous reviews evidence base necessitate a comprehensive review research concerning efficacy as strategy. A systematic qualitative relevant published between January 1990 2013 was undertaken. Inclusion criteria were studies that evaluated effectiveness in deterring employee use or reducing accident injury rates. Methodological adequacy assessed using assessment tool specifically designed to assess quality intervention studies. total 23 reviewed assessed, six which reported on 17 occupational No involved randomised control trials. Only one study demonstrating strong methodological rigour. That found random alcohol reduced fatal accidents transport industry. majority contained weaknesses including; inappropriate design, limited sample representativeness, ecological data evaluate individual behaviour change failure adequately for potentially confounding variables. This latter finding is consistent with indicates improving safety at best tenuous. Better dissemination current relation required support evidence-informed policy practice. There also pressing need more methodologically rigorous utility testing.
