The one-day prevalence rate for psychotropic drugs prescription was 54.9% for men and 45.0% for women (%2=3.98, P<0.05). The two hospitals with psychiatry wards, UH and SCH, had a higher prevalence of psychotropic drugs prescription, 48.9% and 55.6%, respectively, than the hospital without a psychiatry ward (SPH), which had a prevalence of 40.4% (%2=6.05, P<0.05). Among the disciplines, the PSYCH ward had the highest psychotropic drugs prevalence, with 93.4% of its population receiving psychotropic drugs. Corresponding ward rates were 62.8% for SURG, 47.2% for MED, 28.6% for OBGYN and 18.5% for PED 18.5% (%2=88.49, P<0.0001). There were significant differences in the prevat lence rate among different age groups. The prevalence rate increased with age until age 59, after which it started to decline (X2=45.75, P<0.0001).
Class and type of psychotropic drugs prescribed
There were 371 prescriptions of psychotropic drugs for the 223 patients who were prescribed such drugs. Thus, the average prescription per patient was 1.66. Women accounted for 51.2% of the total prescriptions (%2= 12.08, P=0.017), which reflects their proportion of the population studied. UH and SCH, which have p sychiatry wards, accounted for a large proportion of the total psychotropic drugs prescribed – 45% and 41.8%, respectively – while SPH accounted for only 13.2%. However, SPH prescribed more BZD Plus (55.1%) than UH (48.6%) and SCH (51.0%), (%2=9.9, P<0.01). Psychiatry wards accounted for 43.7% of all pre tcriptions for psythotropic drugs and the greatest variety. MED prescribed 28.9%, while SURG, OBGYN and PED accounted for 17.3%, 7.5% and 2.7% of the total psychotropic drugs prescribed, respectively.
