Abstract
AbstractObjectiveTo see if patient satisfaction with psychotropics (PSP) could be used as a patient-oriented outcome variable in the evaluation of PSP drugs in clinical epidemiological studies, relationships between PSP, clinical status, QoL, compliance and the type of antipsychotic were analyzed. Elements of validation of PSP were also assessed.MethodIn a 6-month prospective study, 933 schizophrenic outpatients with initiation or change to their antipsychotic treatment were enrolled. Psychiatrists completed five CGI-SCH scales (positive, negative, cognitive, depressive and global), hospitalization, compliance, and prescription variables. Patients completed PSP, EuroQoL scales, sexual function and compliance variables.ResultsA satisfactory structural equation model was obtained showing significant relationships PSP/compliance (coef. = 0.16), QoL/PSP (coef. = 0.37), clinical status/QoL (coef. = 0.61), clinical status/compliance (coef. = 0.09). Patients receiving olanzapine were more satisfied than patients receiving other atypicals (coef. =0 12) and had better clinical status than patients treated with typicals (coef. = 0.08). Evolution of PSP was related to clinical status, QoL, and continuation of treatment (all P < 001). Sensitivity to change of PSP was moderate (effect size = 0.2).ConclusionPSP produced consistent results in relation to validated outcome variables. However, a single-item measure was not sufficiently sensitive to change. Multi-item questionnaires evaluating different dimensions are needed.
