Interprofessional geriatric and palliative care intervention associated with fewer hospital days

Background: With increasing complexity of our aging inpatient population, we implemented an interprofessional geriatric and palliative care intervention on a hospitalist service. This study aimed to measure the intervention's impact on length of stay (LOS), 30-day readmission, and the daily intensity of inpatient services utilization.

Methods: Using a nonrandomized controlled intervention at a 1000-bed U.S. academic quaternary medical center, we studied 13,941 individuals admitted to a general medicine hospitalist service (of which 5644 were age > =65 years); 1483 were on intervention teams (576 age > =65 years), 5413 concurrent controls, and 7045 historical controls. On 2 of 11 hospitalist teams, a geriatrician, palliative care physician and social worker attended multidisciplinary discharge rounds twice weekly, to recommend inpatient geriatric or palliative care consult (GPCC), postacute nursing or home care, versus postdischarge outpatient consultation. We measured the difference in improvement over time between intervention and control team patients for the following: (1) LOS adjusted for case-mix index, (2) 30-day readmissions, and (3) intensity of hospital service utilization (mean services provided per patient per day).

Results: Adjusted LOS (in hospital days) was decreased by 0.36 days (p = 0.039) for the 1483 patients in the intervention teams, with greater LOS reduction of 0.55 days per admission (p = 0.022) on average among the subset of 576 older patient admissions. Readmissions were unchanged (-1.17%, p = 0.48 for all patients; 1.91%, p = 0.46 for older patients). However, the daily relative value unit (RVU) utilization was modestly increased for both the overall and older subgroup, 0.35 RVUs (p = 0.041) and 0.74 RVUs (p < 0.001) per patient-day on average across the intervention teams, respectively.

Conclusion: An interprofessional intervention of geriatric and palliative care consultation in collaboration with a hospitalist service may reduce LOS, especially for geriatric patients, without an increase in readmissions. This model may have broader implications for hospital care and should be further studied.
