Compliance with and knowledge of the purpose of their medicines 10 days after discharge from hospital. The mean compliance score in patients taking part in the self medication programme was 95% compared with 83% in the control group (difference 12%, 95% confidence interval 4% to 21%; P < 0.02). Of the patients in the self medication group, 90% (38/42) knew the purpose of their drugs compared with 46% (17/37) in the control group (difference 44%, 26% to 63%; P < 0.001).
