title: Evaluation of a four- versus six-week length of stay in the Navy's alcohol treatment program.
abstract: OBJECTIVE
  Attempts to balance escalating health care costs with resource downsizing have prompted alcohol treatment directors in the U.S. Navy to consider reducing the standard length of stay in treatment. The objectives of this study were to (1) determine whether a 4-week inpatient treatment program is as effective as a 6-week program, and (2) explore the potential for matching patients to a 4- or 6-week program according to the severity of their condition at intake.
  
  
  METHODS
  A total of 2,823 active-duty alcohol-dependent inpatients (2,685 men, 138 women) at 12 Navy treatment facilities participated in the evaluation. All facilities conducted a 6-week program until data had been collected for 1,380 participants; they then switched to a 4-week program (n = 1,443). Background information and clinical profile were obtained when patients entered treatment; 1-year outcome data (e.g., alcohol use, behavior problems, job performance, quality of life) were obtained from participants, work supervisors and aftercare advisors. Hierarchical multiple regression analyses were used to assess the effect of length of stay on outcome and to examine patient-program interactions.
  
  
  RESULTS
  The single best predictor of success at 1 year was months of aftercare attendance. Program membership failed to explain any of the observed differences in the criterion measures, once the effects of other predictors had been taken into account. Severity of condition and patient-program interactions were likewise nonsignificant.
  
  
  CONCLUSIONS
  It was concluded that a reduction in length of stay from 6 weeks to 4 weeks in the Navy's inpatient alcohol treatment program would not have an adverse effect on outcome.
