Evaluation of an intervention to change benzodiazepine-prescribing behavior in a prepaid group practice setting . To determine the effect of two levels of educational intervention on benzodiazepine-prescribing behavior in an elderly population in a controlled prepaid group practice ( PPGP ) setting , we designed a prospective controlled trial , with six-month follow-up . Our setting was a 270,000 member group-model PPGP in Colorado , from 1990 to 1991 . Participants included 91 physicians , 62 men and 29 women ; median age was 38.7 years . Group 1 received a one-on-one educational presentation by a clinical pharmacist , written educational materials , a brief follow-up visit , and feedback with recommendations . Group 2 received only a face-to-face presentation , given to departmental groups , as well as the same written educational materials used in group 1 . Controls received no intervention . Our primary outcome measure was the benzodiazepine " on/off " status of the elderly PPGP members . The secondary outcome measure was the median change ( preintervention minus postintervention ) in a standardized amount of benzodiazepines prescribed per physician . Logistic regression analysis failed to show a significant effect on postintervention benzodiazepine on/off status between study groups , when controlling for preintervention on/off status , PPGP-member age , PPGP-member gender , and all possible interactions . Analysis of variance failed to demonstrate an effect of either intervention on the median change in standardized amount of benzodiazepines prescribed per physician , with groups 1 , 2 , and controls yielding values of -278 ( range : -4,137 , 2,844 ) , -330 ( -1,531 , 1,358 ) , and -541 ( range : -3,716 , 2,185 ) , respectively . We conclude that strategies effective in changing physician prescribing behavior in other settings may not be effective in a PPGP setting with benzodiazepines in the elderly as the target for change .
