  1. * Comparison of Intervention and Control groups post intervention after adjusting for pre-intervention results and statistically significant covariates. Notes: Percentages were calculated from residents present during both audits. The category "psychotropics" include residents prescribed any of benzodiazepines, antipyschotics or antidepressants. Marked PRN (& not Reg.) refers to medications administered as the occasion arose but not regularly administered.
