| Summary: | BACKGROUND AND AIMS:The effects of physician specialty on the outcome of heart disease remains incompletely understood because of inconsistent findings from some previous studies. Our purpose is to compare the admission outcomes of heart disease in patients receiving care by cardiologists and noncardiologist (NC) physicians. METHODS:Using reimbursement claims data of Taiwan's National Health Insurance from 2008-2013, we conducted a matched study of 6264 patients aged ≥20 years who received a cardiologist's care during admission for heart disease. Using a propensity score matching procedure adjusted for sociodemographic characteristics, medical condition, and type of heart disease, 6264 controls who received an NC physician's care were selected. Logistic regressions were used to calculate odds ratios (ORs) with 95% confidence intervals (CIs) for complications and mortality during admission for heart disease associated with a cardiologist's care. RESULTS:Patients who received a cardiologist's care had a lower risk of pneumonia (OR = 0.61; 95% CI, 0.53-0.70), septicemia (OR = 0.49; 95% CI, 0.39-0.61), urinary tract infection (OR = 0.76; 95% CI, 0.66-0.88), and in-hospital mortality (OR = 0.37; 95% CI, 0.29-0.47) than did patients who received an NC physician's care. The association between a cardiologist's care and reduced adverse events following admission was significant in both sexes and in patients aged ≥40 years. CONCLUSION:We raised the possibility that cardiologist care was associated with reduced infectious complications and mortality among patients who were admitted due to heart disease.
