Abstract
BACKGROUND: New cases of COVID-19 continue to occur daily in the United States, and the need for medical treatments continues to grow. Knowledge of the direct medical costs of COVID-19 treatments is limited. OBJECTIVE: To examine the characteristics of older adults with COVID-19 and their costs for COVID-19-related medical care. DESIGN: Retrospective observational study. SETTING: Medical claims for Medicare fee-for-service (FFS) beneficiaries. PATIENTS: Medicare FFS beneficiaries aged 65 years or older who had a COVID-19-related medical encounter during April through December 2020. MEASUREMENTS: Patient characteristics and direct medical costs of COVID-19-related hospitalizations and outpatient visits. RESULTS: Among 28.1 million Medicare FFS beneficiaries, 1 181 127 (4.2%) sought COVID-19-related medical care. Among these patients, 23.0% had an inpatient stay and 4.2% died during hospitalization. The majority of the patients were female (57.0%), non-Hispanic White (79.6%), and residents of an urban county (77.2%). Medicare FFS costs for COVID-19-related medical care were $6.3 billion; 92.6% of costs were for hospitalizations. The mean hospitalization cost was $21 752, and the mean length of stay was 9.2 days; hospitalization cost and length of stay were higher if the patient needed a ventilator ($49 441 and 17.1 days) or died ($32 015 and 11.3 days). The mean cost per outpatient visit was $164. Patients aged 75 years or older were more likely to be hospitalized, but their hospitalizations were associated with lower costs than for younger patients. Male sex and non-White race/ethnicity were associated with higher probability of being hospitalized and higher medical costs. LIMITATION: Results are based on Medicare FFS patients. CONCLUSION: The COVID-19 pandemic has resulted in substantial disease and economic burden among older Americans, particularly those of non-White race/ethnicity. PRIMARY FUNDING SOURCE: None.
