A good time to panic? Premorbid and postmorbid panic disorder in heart failure affects cardiac and psychiatric cause admissions

Australas Psychiatry. 2015 Apr;23(2):124-7. doi: 10.1177/1039856214568211. Epub 2015 Jan 27.

Abstract

Objective: The authors sought to identify characteristics associated with premorbid and postmorbid panic disorder onset in relation to heart failure (HF) onset, and examine the effect on unplanned hospital admissions.

Methods: In a two-stage screening process, 404 HF patients admitted to three hospitals in South Australia were referred for structured psychiatric interview when any of the following four criteria were met: (a) Patient Health Questionnaire≥10; (b) Generalized Anxiety Disorder Questionnaire≥7); (c) positive response to one-item panic attack screener; (d) or evidence of suicidality.

Results: A total of 73 referred HF patients (age 60.6±13.4, 47.9% female) were classified into three groups: premorbid panic disorder (27.4%), postmorbid panic disorder (24.7%), and no panic disorder (47.9%). Postmorbid panic disorder was associated with more psychiatric admissions and longer hospital stay in the 6 months prior to the index psychiatric assessment, and also in the 6 months after the index psychiatric assessment (all p<.05 unadjusted). In sensitivity analysis, years since panic disorder onset were associated with longer cardiac length of stay (β=.34, p=.03).

Conclusions: Panic disorder onset in relation to HF diagnosis was associated with discrete patterns of hospital admissions for cardiac and psychiatric causes.
