Neck of Femur Fractures within Two Hours of a Meal

Abstract

Aim: To determine in older hospitalized patients the prevalence of neck of femur (NOF) fractures occurring within two hours of a meal and the factors associated with these fractures. Methods:A prospective study was undertaken within the orthopedic unit of a 320 bed general hospital. Consecutive first admissions of patients aged 70 years and over with fragility NOF fractures between March and November 2011 were included. Patients or their careers were interviewed using a standardised questionnaire.Results: 120 patients were recruited. The median age was 84.0 years. Falls within two hours of a meal occurred in 20.8% of patients. Independent factors associated with falls occurring within two hours of a meal were symptoms of hypotension prior to a fall (OR 5.2, CI 1.342-20.129; P=0.017) and being in residential care (OR 3.0, CI 1.009-8.687; P=0.048). Conclusion:Patients who sustained a NOF fracture within two hours of a meal were more likely to be from residential care and experience symptoms associated with hypotension before the fall compared with patients who experienced a fall after two hours of a meal; identification of the reasons for hypotension and potential management strategies require further investigation.
