Attitudes toward antipsychotic treatment among patients with bipolar disorders and their clinicians: a systematic review

INTRODUCTION Antipsychotics are recommended as first-line therapy for acute mania and maintenance treatment of bipolar disorder; however, published literature suggests their real-world use remains limited. Understanding attitudes toward these medications may help identify barriers and inform personalized therapy. This literature review evaluated patient and clinician attitudes toward the use of antipsychotics for treating bipolar disorder. MATERIALS AND METHODS A systematic search of the Cochrane Library, Ovid MEDLINE, Embase, and BIOSIS Previews identified English language articles published between January 1, 2000, and June 15, 2016, that reported attitudinal data from patients, health care professionals, or caregivers; treatment decision-making; or patient characteristics that predicted antipsychotic use for bipolar disorder. Results were analyzed descriptively. RESULTS Of the 209 references identified, 11 met the inclusion criteria and were evaluated. These articles provided attitudinal information from 1,418 patients with bipolar disorder and 1,282 treating clinicians. Patients' attitudes toward antipsychotics were generally positive. Longer duration of clinical stability was associated with positive attitudes. Implementation of psychoeducational and adherence enhancement strategies could improve patient attitudes. Limited data suggest clinicians' perceptions of antipsychotic efficacy and tolerability may have the greatest impact on their prescribing patterns. Because the current real-world evidence base is inadequate, clinician attitudes may reflect a relative lack of experience using antipsychotics in patients with bipolar disorder. CONCLUSION Although data are very limited, perceived tolerability and efficacy concerns shape both patient and clinician attitudes toward use of antipsychotic drugs in bipolar disorder. Additional studies are warranted.
