Panic disorder and suicidal ideation in primary care.

The purpose of this study was to ascertain whether panic disorder (PD) and suicidal ideation are associated in an inner-city primary care clinic and whether this association remains significant after controlling for commonly co-occurring psychiatric disorders. We surveyed 2,043 patients attending a primary care clinic using the Primary Care Evaluation of Mental Disorders (PRIME-MD) Patient Health Questionnaire, a screening instrument that yields provisional diagnoses of selected psychiatric disorders. We estimated the prevalence of current suicidal ideation and of common psychiatric disorders including panic disorder and major depression. A provisional diagnosis of current PD was received by 127 patients (6.2%). After adjusting for potential confounders (age, gender, major depressive disorder [MDD], generalized anxiety disorder, and substance use disorders), patients with PD were about twice as likely to present with current suicidal ideation, as compared to those without PD (adjusted odds ratio [AOR] = 1.84; 95% confidence interval [CI]: 1.06-3.18; P = .03). After adjusting for PD and the above-mentioned potential confounders, patients with MDD had a sevenfold increase in the odds of suicidal ideation, as compared to those without MDD (AOR = 7.00; 95% CI: 4.42-11.08; P < .0001). Primary care patients with PD are at high risk for suicidal ideation, and patients with PD and co-occurring MDD are at especially high risk. PD patients in primary care thus should be assessed routinely for suicidal ideation and depression.
