Emergency readmissions following geriatric ground-level falls: How does frailty factor in?

BACKGROUND

Ground-level falls (GLFs) in older adults are increasing as life expectancy increases, and more patients are being discharged to skilled nursing facilities (SNFs) for continuity of care. However, GLF patients are not a homogenous cohort, and the role of frailty remains to be assessed. Thus, the aim of this study is to examine the impact of frailty on the in-hospital and 30-day outcomes of GLF patients.

MATERIALS AND METHODS

This is a cohort analysis from the Nationwide Readmissions Database 2017. Geriatric (age ≥65 years) trauma patients presenting following GLFs were identified and grouped based on their frailty status. The associations between frailty and 30-day mortality and emergency readmission were examined by multivariate regression analyses adjusting for patient demographics and injury characteristics.

RESULTS

A total of 100,850 geriatric GLF patients were identified (frail: 41% vs. non-frail: 59%). Frail GLF patients were younger (81[74-87] vs. 83[76-89] years; p<0.001) and less severely injured-Injury Severity Score [ISS] (4[1-9] vs. 5[2-9]; p<0.001). Frail patients had a higher index mortality (2.9% vs. 1.9%; p<0.001) and higher 30-day readmissions (14.0% vs. 9.8%; p<0.001). Readmission mortality was also higher in the frail group (15.2% vs. 10.9%; p<0.001), with 75.2% of those patients readmitted from an SNF. On multivariate analysis, frailty was associated with 30-day mortality (OR 1.75; p<0.001) and 30-day readmission (OR 1.49; p<0.001).

CONCLUSION

Frail geriatric patients are at 75% higher odds of mortality and 49% higher odds of readmission following GLFs. Of those readmitted on an emergency basis, more than one in seven patients died, 75% of whom were readmitted from an SNF. This underscores the need for optimization plans that extend to the post-discharge period to reduce readmissions and subsequent high-impact consequences.
