Effect of early surgery after hip fracture on mortality and complications: systematic review and meta-analysis.

ABSTRACT: BACKGROUND: Guidelines exist for the surgical treatment of hip fracture, but the effect of early surgery on mortality and other outcomes that are important for patients remains unclear. We conducted a systematic review and meta-analysis to determine the effect of early surgery on the risk of death and common postoperative complications among elderly patients with hip fracture. METHODS: We searched electronic databases (including MEDLINE and EMBASE), the archives of meetings of orthopedic associations and the bibliographies of relevant articles and questioned experts to identify prospective studies, published in any language, that evaluated the effects of early surgery in patients undergoing procedures for hip fracture. Two reviewers independently assessed methodologic quality and extracted relevant data. We pooled data by means of the DerSimonian and Laird random-effects model, which is based on the inverse variance method. RESULTS: We identified 1939 citations, of which 16 observational studies met our inclusion criteria. These studies had a total of 13 478 patients for whom mortality data were complete (1764 total deaths). Based on the five studies that reported adjusted risk of death (4208 patients, 721 deaths), irrespective of the cut-off for delay (24, 48 or 72 hours), earlier surgery (i.e., within the cut-off time) was associated with a significant reduction in mortality (relative risk [RR] 0.81, 95% confidence interval [CI] 0.68-0.96, p = 0.01). Unadjusted data indicated that earlier surgery also reduced in-hospital pneumonia (RR 0.59, 95% CI 0.37-0.93, p = 0.02) and pressure sores (RR 0.48, 95% CI 0.34-0.69, p < 0.001). INTERPRETATION: Earlier surgery was associated with a lower risk of death and lower rates of postoperative pneumonia and pressure sores among elderly patients with hip fracture. These results suggest that reducing delays may reduce mortality and complications.

Project description:Hip fracture is associated with substantial morbidity and mortality, especially among the elderly. Current evidence on the association between cigarette smoking and mortality in hip-fracture patients is controversial. We performed a systematic review and meta-analysis of studies on this association. The databases Medline/PubMed, Embase, Web of Science, and Cochrane Library were searched for studies that estimated the effect of smoking on the risk of mortality in hip-fracture patients. Pooled analyses were conducted of the associations, expressed in relative risk (RR) and 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistic. Study quality was assessed by the modified Newcastle-Ottawa Scale (NOS) and publication bias was evaluated by a funnel plot, Begg's and Egger's tests. Subgroup analyses were performed by study design, race/ethnicity, age ≥60 years, smoking status, and follow-up period. A total of six articles involving 3739 hip-fracture patients were included in the meta-analysis. Our results indicate that ever-active smoking was significantly associated with an increased risk of death in hip-fracture patients (pooled RR=1.26; 95% CI: 1.08-1.46). In further subgroup analysis, the risk of death was significantly higher in ever-active smokers than in never smokers in White participants (pooled RR=1.23; 95% CI: 1.05-1.44) and elderly aged ≥60 years (pooled RR=1.19; 95% CI: 1.01-1.40), with no significant association in Asian participants (pooled RR=1.42; 95% CI: 0.95-2.11). Current smokers had more risk of death than never smokers (pooled RR=1.26; 95% CI: 1.08-1.46). The association was significant in follow-up periods of ≤1 year (pooled hazard ratio, HR=1.34; 95% CI: 1.05-1.71), 3 years (pooled HR=1.22; 95% CI: 1.05-1.43), and 5 years (pooled HR=1.26; 95% CI: 1.08-1.46). Cigarette smoking is associated with an increased risk of mortality in hip-fracture patients, especially in elderly patients aged ≥60 years, current smokers, and White participants. With the extension of follow-up period, the effect on mortality of smoking is profound and lasting.

Project description:BackgroundPerioperative management of patients with hip fracture patients receiving oral anticoagulants requires navigating the risks associated with surgical delay and perioperative hemostasis. The aim of this systematic review and meta-analysis was to evaluate the effect of expedited-surgery protocols on time to surgery and perioperative outcomes in anticoagulant-treated patients with hip fracture.MethodsWe searched MEDLINE, Embase and CENTRAL from inception to May 5, 2020, to identify English-language studies reporting outcomes after expedited hip fracture surgery in patients receiving vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) before hospital admission. We performed a meta-analysis using Mantel-Haenszel weighting for dichotomous variables and inverse variance weighting for continuous variables.ResultsAmong the 4253 citations identified, 14 studies were included. In the 6 studies eligible for meta-analysis, compared to hip fracture surgery before implementation of a VKA-reversal protocol, surgery after implementation of such a protocol was associated with a significant reduction in time to surgery (mean difference 45.31 h, 95% confidence interval [CI] 15.81 h to 74.80 h). Expedited surgery (within 48 h) in patients who received DOACs preoperatively was not associated with increased surgical duration (mean difference -7.29 min, 95% CI -22.5 min to 7.95 min) or 30-day mortality (odds ratio [OR] 1.30, 95% CI 0.49 to 3.89) compared to patients who did not receive anticoagulants (control patients). However, expedited surgery in DOAC-treated patients was associated with an increased blood transfusion risk compared to control patients (OR 0.58, 95% CI 0.36 to 0.96).ConclusionImplementing a VKA-reversal protocol for patients with hip fracture is effective in decreasing time to surgery, without an increased bleeding risk. Performing hip fracture surgery within 48 hours in DOAC-treated patients is also safe, with a small increase in blood transfusion risk.
