Medication Management Decisions in Schizophrenia

描述：抗精神病药物对精神分裂症非常有效。

DESCRIPTION: Antipsychotic medications are highly effective in schizophrenia. Controlled clinical research provides evidence for objective quality standards concerning the selection, dose, duration, and route of administration of antipsychotic medications. Yet, prescribing patterns vary widely, with many patients receiving medication regimens that are inconsistent with these standards. This presumably results in poorer patient outcomes. Surprisingly, very little is known about what has impeded translation of the research findings into clinical practice and why psychiatrists so often prescribe antipsychotic medications in a manner that is not supported by the research literature. This study tests a multidimensional model of medication management decision making. The model incorporates effects of the patient, provider, and treatment environment on the quality of antipsychotic medication management. The overall aim is to identify targets for quality improvement by defining specific critical points in the medication management decision-making process. The main study will have two phases. First, nationally representative survey data will be collected on the knowledge of antipsychotic medications, acceptance of guidelines, clinical confidence, motivation to change practice, and organizational and practice constraints of a randomly selected sample of 1,600 members of the American Psychiatric Association. In the second phase, the psychiatrists will provide information on the medication management and the clinical service and economic characteristics of three randomly selected patients with schizophrenia from their practices. The quality of medication management will be assessed by measuring conformance with treatment recommendations developed by the AHRQ/NIMH Schizophrenia Patient Outcomes Research Team (PORT). Information from both phases of the study will be used to identify specific modifiable patient, psychiatrist, and practice characteristics that promote or impede conformance with the treatment recommendations. The results will inform quality improvement programs by identifying key modifiable determinants of the quality of medication management in the community treatment of schizophrenia.
