Background: Psychiatric disorders and hypertension both independently increase risk for heart disease, cardiac events, and healthcare utilization. However, the contribution of specific psychiatric disorders to healthcare utilization in persons with hypertension is unknown.
Objective: To evaluate associations between psychiatric disorders and receipt of hospital care in people with hypertension.
Design: Cross-sectional epidemiologic survey.
Subjects: A total of 8,812 hypertensive individuals drawn from a randomly selected sample of 43,093 US adults.
Main outcomes: Participants were assessed in-person for a range of mental disorders (using the Diagnostic and Statistical Manual of Mental Disorders-IV), hypertension status (self-report), and past-year occurrence of emergency room treatment and overnight hospital stay (self-report).
Results: After controlling for demographics and clinical variables, persons having any lifetime mood, anxiety, or personality disorders had increased likelihood of emergency room treatment [odds ratios (ORs) = 1.26, 1.18, and 1.47, respectively]. Persons having any mood or personality disorder had increased likelihood of overnight hospital stay (ORs = 1.24 and 1.31, respectively). The specific disorders significantly associated with emergency room treatment were lifetime major depression, lifetime manic disorder, past-year major depression, past-year manic disorder, past-year panic disorder without agoraphobia, and paranoid, histrionic, antisocial, obsessive-compulsive personality disorders, with ORs ranging from 1.25 to 2.41. The specific disorders significantly associated with overnight hospital stay were lifetime dysthymia, lifetime manic disorder, past-year major depression, past-year manic disorder, and histrionic, antisocial, and paranoid personality disorders, with ORs ranging from 1.40 to 1.87.
Conclusion: Results suggest that addressing mental health problems in persons with hypertension may decrease healthcare utilization.
