Factors associated with pharmacologic noncompliance in patients with mania.

Background: Studies of noncompliance with pharmacotherapy in bipolar disorder have primarily involved outpatients receiving lithium. There are limited data to date regarding the rates of noncompliance in patients with bipolar disorder and schizoaffective disorder hospitalized for recurrent mania. Similarly, the influence of race, illness phenomenology, and comorbid psychiatric and medical disorders and the treatment with antipsychotics, antidepressants, and mood-stabilizing agents other than lithium on noncompliance in this population have not been systematically examined.

Method: Patients hospitalized for acute mania (N = 101) were evaluated by the Structured Clinical Interview for DSM-III-R to establish diagnosis and comorbidity and the Young Mania Rating Scale and Hamilton Rating Scale for Depression to assess severity of manic and depressive symptoms, respectively. Compliance was assessed by responses to a clinician-administered questionnaire administered to the patient, treaters, and significant others and by admission plasma concentrations of mood-stabilizing agents.

Results: Sixty-five patients (64%) were noncompliant with their pharmacologic regimen in the month prior to admission as defined by criteria for full compliance and partial or total noncompliance. Noncompliance was significantly associated with greater severity of mania upon admission (p = .02) and treatment with combinations of mood stabilizers (p = .01).

Conclusion: Noncompliance with pharmacotherapy was present in the majority of patients admitted for acute mania and was associated with greater severity of mania upon admission and treatment with combinations of mood stabilizers.
