Mental disorders, quality of care, and outcomes among older patients hospitalized with heart failure: an analysis of the national heart failure project.
OBJECTIVE
To evaluate the effect of a mental illness diagnosis on quality of care and outcomes among patients with heart failure.


METHODS
Retrospective, national, population-based sample of patients with heart failure hospitalized from April 1, 1998, through March 31, 1999, and July 1, 2000, through June 30, 2001.


METHODS
Nonfederal US acute care hospitals.


METHODS
A total of 53 314 Medicare beneficiaries.


METHODS
Quality of care measures, including left ventricular ejection fraction (LVEF) assessment, prescription of an angiotensin-converting enzyme (ACE) inhibitor at discharge among patients without treatment contraindications, and 1-year readmission and 1-year mortality.


RESULTS
Of the patients included in the study, 17.0% had a mental illness diagnosis. Compared with patients without mental illness diagnoses, eligible patients with mental illness diagnoses had lower rates of LVEF evaluation (53.0% vs 47.3%; P < .001) but comparable rates of ACE inhibitor prescription (71.3% vs 69.7%; P = .40). Findings were unchanged after multivariate adjustment: patients with mental illness had lower odds of LVEF evaluation (odds ratio [OR], 0.81; 95% confidence interval [CI], 0.76-0.87) but comparable rates of ACE inhibitor prescription (0.96; 0.80-1.14). Patients with mental illness diagnoses had higher crude rates of 1-year all-cause readmission (73.7% vs 68.5%; P < .001), which persisted after multivariate adjustment (OR, 1.30; 95% CI, 1.21-1.39). Crude 1-year mortality was higher among patients with a mental illness diagnosis (41.0% vs 36.2%; P < .001). Presence of a comorbid mental illness diagnosis was associated with 1-year mortality after multivariate adjustment (OR, 1.20; 95% CI, 1.12-1.28).


CONCLUSIONS
Mental illness is commonly diagnosed among elderly patients hospitalized with heart failure. This subgroup receives somewhat poorer care during hospitalization and has a greater risk of death and readmission to the hospital.
