OBJECTIVE: To describe the prevalence and clinical characteristics of
primary care patients who report suicidal ideation during the month be
fore their medical visit. DESIGN: Analysis of a self-administered suic
idal ideation screening item using sociodemographic data, treatment hi
story, and clinical data from structured interviews. SETTING: Three Rh
ode Island private family practices, a South Carolina family medicine
residency, and a California prepaid internal medicine group practice.P
ATIENTS: Adult primary care patients (N = 2,749), 18 to 70 years old,
who are able to read and write English, able to complete study forms,
and willing to provide informed consent. RESULTS: Sixty-seven (2.44%)
of the patients reported suicidal ideation (''feeling suicidal'') duri
ng the past month, and most of these patients (58.2%) received no ment
al health care during that time. The adjusted risk of suicidal ideatio
n was significantly elevated for patients with self-reported fair or p
oor physical health (odds ratio [OR] 2.5: 95% confidence interval [CI]
1.5, 4.1), fair to poor emotional health (OR 18.0; 95% CI 8.8, 37.0),
marital distress (OR 4.4: 95% CI 2.2, 8.8), and recent mental health-
related work loss (OR 6.3; 95% CI 3.7, 10.5). In the California sample
, patients with major depression (OR 31.2; 95% CI 12.8, 76.1), general
ized anxiety disorder (OR 23.4: 95% CI 8.1, 67.1), and drug abuse or d
ependence (OR 9.6; 95% CI 2.9, 31.6) were at increased risk of suicida
l ideation. The ''feeling suicidal'' item identified 10 of 12 patients
who acknowledged a recent plan to kill themselves. CONCLUSIONS: In th
ese primary care patients, suicidal ideation is strongly associated wi
th mental disorder and mental health-related functional impairment, an
d can be detected with a single self-report ''feeling suicidal'' item.
