title: Impact of a workplace peer-focused substance abuse prevention and early intervention program.
abstract: BACKGROUND
  PeerCare is a workplace peer intervention program that focuses on changing workplace attitudes toward on-the-job substance use and trains workers to recognize, intervene with, and refer coworkers who have a problem.
  
  
  METHODS
  Monthly injuries at the study company (January 1983 through June 1996) were compared to counts at four other companies in the same industry. Using these panel data, fixed-effects negative binomial regression measured the association of the percentage of the workforce covered by PeerCare with the workplace injury rate.
  
  
  RESULTS
  For every 1% increase in the workforce covered with PeerCare, the risk of injury declined by 0.9984 (95% confidence interval, 0.9975-0.9994). These findings suggest that, by June 1996, when 86% of the workforce was covered under PeerCare, the program had reduced injury rates by an average 14% per month.
  
  
  CONCLUSIONS
  The findings support the implementation of peer intervention programs as a means to reduce workplace injuries.
