Abstract

Introduction: Medicare patients account for over 50% of hospital days at a cost of over $1 trillion per year. Yet, hospitalization of older adults often results in poor outcomes. We evaluated the role of geriatrician-hospitalists in the care of older adults. Materials and methods A retrospective cohort study was conducted in a 764-bed tertiary care hospital with patients 65 and older admitted to medicine. Geriatrician-hospitalists care was compared to usual care by non-geriatrician hospitalists (staff and non-staff). Outcome measures included length of stay (LOS) and 30-day readmissions. Process measures included geriatric-focused care practices, such as early mobilization, safety precautions, delirium management, use of potentially inappropriate medications and documentation of advanced directives as well as discharge disposition.

Results: Of the 10,529 patients, 2949 (28.0%) were cared for by staff hospitalists, 7181 (68.2%) by non-staff hospitalists and 399 (3.79%) by geriatrician-hospitalists. Patients cared for by geriatrician-hospitalists were significantly older with more comorbidities than those admitted to staff and non-staff hospitalists (average age: 86.3, 79.7, and 80.3, respectively, p < 0.0001; Charlson Comorbidity Index: 7.46, 7.01, and 7.17, respectively, p = 0.0005). Multivariate analysis showed no difference in LOS, 30-day readmissions, and discharge disposition. In terms of care practices, significant differences were found for the following: time to PT (p < 0.0001), duration of indwelling bladder catheters (p = 0.018), documentation of Do-Not-Resuscitate (p < 0.0001), benzodiazepine use (p < 0.0001) and anticholinergics (p = 0.0029), respectively.

Conclusions: As the population continues to age at unprecedented rates and hospitals struggle to meet the demands and expectations, geriatrician-hospitalists may improve care practices important for older adult care management.
