    Abstract:
    BACKGROUND: We examined possible associations between different red blood cell (RBC) transfusion strategies, overall quality of life (OQoL), and recovery of activities of daily living (ADL) in operated frail elderly hip fracture patients, and the possibility that OQoL was related to ADL recovery. METHODS: A prospective, assessor-blinded, randomized controlled trial was carried out among 157 elderly residents (≥65 years) from nursing homes and sheltered housing facilities with Mini-Mental State Examination scores ≥5 points. Patients were assigned to either a restrictive RBC transfusion strategy [hemoglobin (Hb) < 9.7 g/dL, 6 mmol/L] or a liberal strategy (Hb < 11.3 g/dL, 7 mmol/L) during the first 30 days after surgery. An interview-based questionnaire, the depression list (DL) assessing OQoL, and the modified Barthel Index (MBI) assessing ADL performance, were conducted on day 30 and 1 year after hip fracture surgery. Sum-scores of DL, MBI, and their changes from day 30 until 1 year (expressing recovery) were compared between RBC transfusion groups. Possible associations between changes of DL and MBI sum-scores were tested for across total patient population. RESULTS: There was no association between OQoL and RBC transfusion strategies on day 30 or at 1 year. The DL sum-score changes were similar for both groups, (ie, 1.06 points) [95% confidence interval (CI) -0.62, 2.76)] P = .21. The MBI sum-scores increased at 1 year following the liberal transfusion strategy (ie, by 6.86 points) (95% CI 0.41, 13.3) P = .03. Recoveries of OQoL and ADL were associated: β = -0.06 (95% CI -0.11, -0.01) P = .02. CONCLUSIONS: According to our Hb threshold criteria, OQoL and RBC transfusion strategies for frail elderly hip fracture patients are not associated. However, for survivors with less severe dementia, ADL recovery after 1 year is greater following a liberal transfusion strategy than a restrictive strategy. OQoL progress and ADL recovery were associated.
