A national analysis of complications following hemiarthroplasty for hip fracture in older patients

Aim: We sought to better quantify this in terms of comorbidity and complication rates. Design: Retrospective review of national database. Methods: Data on all patients who underwent hip hemiarthroplasty for FNOF between January 2005 and December 2008 were extracted from the English hospital episode statistics database. Results: There were 41 770 patients aged 65-84 years and 35 321 patients aged epsilon 85 years. The older cohort was less likely to have diabetes, chronic obstructive pulmonary disease and rheumatoid arthritis. However, they exhibited a significantly higher risk of lower respiratory tract infection [odds ratio (OR) = 1.58, 95% confidence interval (CI) 1.50-1.67)], myocardial infarction (OR = 1.67, 1.52-1.83) and acute renal failure (OR = 1.54, 1.40-1.70) within 30 days of surgery with an inpatient mortality risk at 90 days, double that of the younger age group. Length of stay (LoS) was significantly longer in patients > 85 years compared to younger patients (median 18 days vs. 15, P < 0.001). Conclusion: Patients aged epsilon 85 years admitted for FNOF were found to have a lower incidence of major chronic disease but exhibited a greater incidence of acute events following hemiarthroplasty and their LoS was increased. Targeted medical interventions that focus upon this susceptible patient group may help reduce morbidity and improve survival.
