Impact of inpatient geriatrics consultation on hospital outcomes in older adults with trauma.

BACKGROUND

Older adults presenting with trauma have worse outcomes than younger adults. Starting in 2016, we provided geriatrics consultation (GC) to older adults admitted to the trauma service. We aimed to analyze the impact of GC on patient outcomes.

METHODS

We performed a retrospective pre-post study and year-matched cohort study. We identified patients from the trauma registry at our level 1 trauma center. In the pre-post study, we compared patients who received GC (2016-2022) with controls (2011-2015). In the cohort study (2016-2022), we compared patients who received GC with controls. We matched for age, race, sex, and injury severity score (ISS) in both studies, as well as admission year in the cohort study. Outcome variables included mortality (in-hospital, 30-day, 90-day), length of stay (LOS), discharge disposition, and hospital readmission rates (30-day, 90-day).

RESULTS

We analyzed 1968 patients in the pre-post study and 2544 patients in the cohort study. Patients were similar in age, race, and sex. GC patients had a slightly higher ISS score and a higher rate of ICU stay. Delirium occurrence was lower among GC patients. GC patients had lower in-hospital mortality compared to controls (pre-post OR 0.27, p < 0.001; cohort OR 0.31, p < 0.001) and increased LOS (6 days vs 4 days, p < 0.001; both studies). GC patients in the cohort study also had lower 30- and 90-day mortality (OR 0.52 and 0.65, p < 0.01) and were less likely to return home (OR 0.81, p < 0.01); similar trends, though not statistically significant, were noted in the pre-post study. Lower readmission rates (statistically non-significant) were noted in the GC group across both studies.

CONCLUSIONS

GC in older adults with trauma has proven benefit with reduced mortality and a trend toward lower readmission rates but was associated with increased LOS and higher rates of discharge to skilled facility.
