Prescripción de antipsicóticos al egreso hospitalario durante el período abril-setiembre de 2012 en el Hospital Vilardebó de Montevideo, Uruguay / Prescribing antipsychotics to hospital discharge during the period April-September 2012 Vilardebó Hospital in Montevideo, Uruguay

Las guías clínicas recomiendan la monoterapia antipsicótica (mta). La polifarmacia antipsicótica (pfa, uso concomitante de dos o más antipsicóticos) es una práctica clínica frecuente. El objetivo del trabajo fue determinar el perfil de prescripción antipsicótica y su uso en mta o pfa, al egreso hospitalario durante el período abril setiembre de 2012 en el Hospital Vilardebó. Se realizó un estudio descriptivo, observacional y retrospectivo. Las variables estudiadas fueron sexo, edad, medicación y diagnóstico. Se definió mta para los que egresaron con un antipsicótico y pfa para aquellos que egresaron con dos o más antipsicóticos. El 52 % egresó con mta, de los cuales el 42% recibió un antipsicótico atípico y el 10%, uno típico. El 48 % restante egresó con dos o más antipsicóticos (pfa). El 19 % de los pacientes con pfa egresó con tres o más antipsicóticos. Es elevado el uso de pfa al egreso hospitalario.

Clinical Correlates and Description Profiles of Antipsychotic Polypharmacy for Patients with Schizophrenia / 신경정신의학

OBJECTIVES: Despite increasing use of antipsychotic polypharmacy (APP), few studies have investigated APP for Korean patients with schizophrenia. The aim of this study was to identify the sociodemographic and clinical correlates and recent prescription profiles of APP in schizophrenia patients. METHODS: A total of 297 schizophrenia patients were recruited and interviewed using standardized assessment instruments in Seoul National Hospital. Differences in demographic and clinical characteristics between APP and antipsychotic monopharmacy (APM) groups were analyzed. The prescriptions of psychotropic drugs were collected by a review of medical records. RESULTS: In comparison with the APM group, the APP group showed association with earlier onset, lower employment rate, and higher scores for Clinical Global Impression-Severity and Brief Psychiatric Rating Scale (BPRS) (p<0.001). In particular, the BPRS positive (p<0.001) and affective symptom scores (p<0.001) of the APP group were higher those of the APM group. The most frequent combination pattern of APP was second generation antipsychotics (SGA)+SGA, followed by SGA+first generation antipsychotics (FGA), and SGA+SGA+FGA. For antipsychotics, it was risperidone+quetiapine, followed by clozapine+risperidone, risperidone+sulpiride, and risperidone+haloperidol. CONCLUSION: The current study suggests that the usage of APP for schizophrenia could be related to symptom severity affected by positive and affective symptoms. The prescription profile reflects that the proportion of atypical antipsychotics on APP has increased.
