106 mortality following hip fracture among nursing home residents

Abstract Background Little is known about mortality following hip fracture among Nursing Home (NH) residents. Prognostic data is important to guide management, including osteoporosis treatment. Methods We conducted a retrospective cohort study of all patients admitted to an Irish tertiary hospital from NHs with hip fracture during the years 2017-2020 inclusive. Mortality was assessed at 90, 180 and 365 days (one-year) following admission. Results One patient was lost to follow up, leaving 233 in the analysis group. 147 were female. Mean age was 85. All-cause mortality was 18.03% at 90 days, 27.04% at 180 days and 37.34% at one year. One-Year Mortality (OYM) was 34.01% among females and 43.02% among males. Among those aged 90 or over, OYM was 45.59% (31/68), being 65.22% (15/23) among males and 35.56% (16/45) among females. In those aged 75 or over, OYM was 39.9% (81/203), being 48.57% (34/70) among males and 35.34% (47/133) among females. In those aged under 75, OYM was 20% (6/30). OYM was 42.31% (11/26) among those who could mobilise independently before fracture, 37.23% (51/137) among those requiring an aid, 33.9% (20/59) among those requiring assistance, and 45.45% (5/11) among those unable to mobilise. 62 Rockwood Clinical Frailty Scales (CFS) were recorded (median score 7, range 5-9). OYM was 0% (0/4) for CFS 5, 50% (8/16) for CFS 6, 31.43% (11/35) for CFS 7, 80% (4/5) for CFS 8 and 100% (0/2) for CFS 9. Conclusion Mortality among NH residents following hip fracture was highest in older males. While mobility before fracture was a poor predictor of mortality, CFS showed promise among a smaller sample size.
