Background:
Fragility fractures are common in care home residents but established tools have not been tested in this population.
Aim:
To identify the most practicable tool for use.
Methods:
DESIGN: Multicentre prospective observational cohort pilot study.
Setting:
18 care homes in Boston, UK.
Assessments:
fragility risk score at baseline with FRAX, QFractureScore, Garvan nomogram, body mass index and TUGT for each participant.
Outcomes:
falls, fractures, combined falls & fractures. Follow-up; 12 months.
Results:
217/618 (35%) residents in the 18 care homes were enrolled. 147 (68%) had mental capacity,70 (32%) did not. There were 325 falls and 10 fractures in participants during the study. At the same time there were 1671 falls and 103 fractures in residents not participating in the study. Multiple regression analyses showed that only age had a statistically significant association with falls (χ2(1) = 5.7775, p = 0.0162), fractures (χ2(1) = 4.7269, p = 0.0297) and combined falls & fractures (χ2(1) = 4.7269, p = 0.0297). C-statistics were: falls; FRAX 0.544, BMI 0.610, QFractureScore 0.554, Garvan nomogram 0.579, TUGT 0.656, fractures; FRAX 0.655, BMI 0.708, QFractureScore 0.736, Garvan nomogram 0.712, TUGT 0.590, combined falls and fractures, c-statistics were same as for fractures. Fifty-four participants (25%) died during follow-up. Charlson comorbidity index predicted mortality, R2 = 0.021 (p = 0.034).
Conclusions:
QFractureScore, BMI and Garvan nomogram were good predictors of fractures and combined falls and fractures Only age had statistically significant association with the outcomes. No tool was good predictor of falls.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
