Factors associated with the course of health-related quality of life after a hip fracture

Introduction The number of hip fracture patients is expected to grow the forthcoming decades. Knowledge of the impact of the fracture on the lives of elderly could help us target our care. The aim of the study is to describe HRQoL (Health-Related Quality of Life) after a hip fracture and to identify factors associated with the course of HRQoL in the first postoperative year. Materials and methods 335 surgically treated hip fracture patients (mean age 79.4 years, SD 10.7, 68 % female) were included in a prospective observational cohort. HRQoL was measured with the SF-12 Health Survey, composed of the Physical and a Mental Component Summary Score (PCS, MCS), at admission (baseline) and at 3 and 12 months postoperatively. Eleven predefined factors known to be associated with the course of HRQoL were recorded: age, gender, physical status, having a partner at admission, living in an institution, prefracture level of mobility, anemia, type of fracture and treatment, delirium during hospital stay and length of stay. Results HRQoL declined between baseline and 3 months, and recovered between three and 12 months. PCS HRQoL did not recover to baseline values, MCS HRQoL did. Age younger than 80 years, ASA classification I and II, higher prefracture level of mobility, intracapsular fracture and treatment with osteosynthesis (compared to arthroplasty) were associated with greater initial decline in PCS HRQoL, none of the recorded factors were significant for decline in MCS HRQoL. Conclusions Both PCS and MCS HRQoL declined after a hip fracture and PCS did not recover to baseline values. Healthier patients may need extra care to prevent them from having a steep decline in postoperative PCS HRQoL and arthroplasty should be considered with low threshold

Validation of the Risk Model for Delirium in hip fracture patients

Objective: The Risk Model for Delirium (RD) score is a 10-item questionnaire that allocates hip fracture patients after admission to hospital to be either at high or at low risk for delirium. This allows targeted preventive actions. Clinical reliability, validity and feasibility of the RD score are discussed. Methods: Demographic data, RD score and delirium incidence of all consecutive admissions for hip fractures in patients 65 years and older were collected. In 102 patients, the RD score was repeated. Interobserver reliability and validity were determined. The correlation between delirium and items both included and not included in the RD score was calculated. Results: A total of 378 patients were included; 102 (27%) were diagnosed with a delirium. The intraclass correlation coefficient of the RD score was 0.77 [confidence interval (CI) 0.68-0.84]. Sensitivity was 80.4% (71.4-87.6), and specificity was 56.2% (50.1-62.1). Area under the receiver operating characteristic curve was 0.73 (CI 0.68-0.77). A multivariable logistic regression analysis showed that besides the RD score, a trochanteric fracture and male gender were independent risk factors for d Conclusions: The RD score is a reliable, feasible and valid instrument for predicting delirium in hip fracture patients.
