Outcome comparison of patients receiving oral or depot neuroleptic medication.

Three outcome measures of psychiatric treatment were retrospectively compared between two groups of acutely hospitalized psychotic patients who had been prescribed either oral haloperidol (n = 58) or depot haloperidol (n = 95) as the only medication at the time of discharge. There were no significant differences between the groups on demographic variables, including sex, age, and ethnicity. There were no significant differences between the groups on keeping the initial outpatient appointment, in readmission history over a 4-yr. follow-up, or in length of time to subsequent readmission, if any. It appears that there is no benefit in choosing one form of medication over the other from a clinical perspective, as neither appears more clinically efficacious when examined on these outcome variables. However, there is a significant difference in cost of the two forms of the medication in favor of the oral form, making the oral form more favorable if cost is to be minimized.
