Preoperative blood test results and type of fracture as transfusional risk factors in patients older than 65 years with trochanteric hip fracture

OBJECTIVE: To determine the effect of risk factors for allogenic blood transfusion in surgery for trochanteric hip fractures. PATIENTS AND METHODS: A retrospective study of all the trochanteric hip fracture patients older than 65 years who underwent surgery to repair trochanteric hip fracture related to osteoporosis in 2000 and 2001 in a regional hospital. Data recorded were age; gender; type of fracture (international AO classification); level of anesthetic risk (ASA classification); hemoglobin concentration and hematocrit upon admission, on the day of surgery and 2 days later; time elapsing between admission and surgery; blood transfusion and blood product use. RESULTS: One hundred two patients (29 men and 73 women) with trochanteric hip fractures were studied. Mean (+/- SD) patient age was 82.9 +/- 8.8 years (range, 65-99 years). Upon admission, mean hemoglobin was 123 +/- 18.1 g/L (range, 56-154 g/L), hematocrit was 37% +/- 5% (range, 10%-40%). Time elapsing until surgery was 3.5 +/- 1.6 days (range, 0-8 days). Admission hemoglobin concentration was lower in patients who required transfusion (116 g/L) than in patients who did not (133 g/L) (P < 0.001). Logistical regression analysis identified only AO classification of fracture type (P < 0.05) and admission hemoglobin concentration (P < 0.001) as independent risk factors for transfusion. CONCLUSIONS: The hemoglobin level at admission and the trochanteric fracture type bear a relation to transfusion needs. These results suggest that in elderly patients we should improve hemoglobin levels and initiate blood salvage measures in order to reduce the need for allogenic blood transfusion, with its inherent risks.     

Association between benzodiazepines use and risk of hip fracture in the elderly people: A meta-analysis of observational studies

ObjectiveHip fracture is one of the leading causes of disability, cost, morbidity, and mortality. Several studies reported that benzodiazepines (BDZs) have been associated with an increased risk of hip fracture in older individuals. The aim of this study was to evaluate the magnitude of hip fracture risk with BDZs.MethodsA systematic literature search on EMBASE, PubMed, Google Scholar, Scopus was performed between January 1, 1980, and March 31, 2019. The search strategy was based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline, and an observational study design was mandatory for articles inclusion. Data were extracted by two authors independently and a random effect model was used to evaluate effect size. The random-effects model (DerSimonian-Laird) was utilized to obtain the overall risk ratio (RR) and its 95% CI for all studies. The Newcastle Ottawa Scale (NOS) was also used to assess the quality of each study.ResultsOf 2315 studies screened, 33 (20 cohorts and 13 case-control) with 169,660 hip fracture cases were included in our analysis. In BDZs users, compared with non-users, the RR for hip fracture was 1.34 (95%CI: 1.26–1.44). The RR for long- and short-short acting BDZs and hip fracture risk were 1.31 (95%CI: 1.18–1.45, P < 0.0001), and 1.15 (95%CI: 1.08–1.22, P < 0.0001), respectively. When stratified by type of users, the current and recent users of BDZs had higher risk of hip fracture (RR: 1.83, 95% CI: 1.46–2.28, P < 0.0001 and RR: 1.61, 95% 1.30–1.99, P < 0.0001) whereas there was no increased risk of hip fracture in past BDZs users (RR: 1.18, 95%CI: 1.07–1.29, P < 0.0001).ConclusionOur meta-analysis showed an increased risk of hip fracture in patients with BDZs compared with non-users. Physicians should be aware of the unwanted consequence of BDZs when they will prescribe BDZs for their patients, especially elderly patients because hip fractures are highly prevalent in the elderly population.

Is operative delay associated with increased mortality of hip fracture patients? Systematic review, meta-analysis, and meta-regression

PURPOSE: Mortality associated with hip fracture is high in elderly patients. Surgical repair within 24 hr after admission is recommended by The Royal College of Physicians' guidelines; however, the effect of operative delay on mortality remains controversial. The objective of this study was to determine whether operative delay increases mortality in elderly patients with hip fracture. METHODS: Published English-language reports examining the effect of surgical delay on mortality in patients who underwent hip surgery were identified from electronic databases. The primary outcome was defined as all-cause mortality at 30 days and at one year. Effect sizes with corresponding 95% confidence intervals were calculated by using a DerSimonian-Laird randomeffects model. RESULTS: Sixteen prospective or retrospective observational studies (257,367 patients) on surgical timing and mortality in hip fracture patients were selected. When a cut-off of 48 hr from the time of admission was used to define operative delay, the odds ratio for 30-day mortality was 1.41 (95% CI = 1.29-1.54, P < 0.001), and that for one-year mortality was 1.32 (95% CI = 1.21-1.43, P < 0.001). CONCLUSIONS: In hip fracture patients, operative delay beyond 48 hr after admission may increase the odds of 30-day all-cause mortality by 41% and of one-year all-cause mortality by 32%. Potential residual confounding factors in observational studies may limit definitive conclusions. Although routine surgery within 48 hr after admission is hard to achieve in most facilities, anesthesiologists must be aware that an undue delay may be harmful to hip fracture patients, especially those at relatively low risk or those who are young.     

Chin-on-Chest in Neck of Femur Fracture (COCNOF) sign: A simple radiographic predictor of frailty and mortality in hip fracture patients

IntroductionFragility fractures are a significant public health challenge often occurring as a result of frailty. Identifying patients who have increased risk of adverse outcomes can aid treating teams in managing these patients appropriately. We hypothesise that the appearance of the patient's head overlapping the lung fields (named Chin on Chest in Neck of Femur sign (COCNOF)) in the admission chest radiograph was a predictor of increased mortality at 3, 6 and 12 months.MethodsAll consecutive patients admitted with hip fracture between 1^st January – 31st December 2019 were analysed. We collected patient characteristics, AMTS score, ASA grade, length of stay, place of discharge, Nottingham Hip Fracture Score, Rockwood Frailty score, Charlson Comorbidity Index and presence of COCNOF sign. The main outcome measures were mortality at 90 days, six months and 12 months following admission.Results469 patients with a mean age of 81.9 (SD 8.4) were included. 18% of patients were COCNOF positive. Univariate analysis showed positive COCNOF sign to be associated with higher mortality at 90 days (19.1 vs 10.8%; RR 1.95, 95%CI 1.05 – 3.63,p=0.03), six months (31.5% vs 14.2%; RR 2.77, 95%CI 1.62 – 4.72, p<0.001) and twelve months (41.6% vs 17.1%; RR 3.45, 95%CI 1.62-4.72, p<0.001). In the multivariate regression models the strongest predictors of mortality were age, gender and CCI it is therefore likely that the COCNOF sign is acting as a surrogate marker of these variables within the univariate models.ConclusionOur results suggest that COCNOF sign is a simple radiographic marker which can be used to identify patients with higher levels of frailty and increased risk of mortality following hip fracture.     

Timing of surgery for hip fractures in the elderly: A retrospective cohort study

IntroductionAlthough early surgery for elderly patients with hip fracture is recommended in existing clinical guidelines, the results of previous studies are inconsistent. The aim of this study was to compare postoperative outcomes of early and delayed surgery for elderly patients with hip fracture.Materials and MethodsIn this retrospective study using a national inpatient database in Japan, patients aged 65 years or older who underwent surgery for hip fracture between July 2010 and March 2014 were included. Early surgery was defined as surgery on the day or the next day of admission. Assessed outcomes included death within 30 days and hospital-acquired pneumonia.ResultsIn this cohort, 47,073 (22.5%) patients underwent surgery for hip fractures within two days of admission (early surgery group) and 161,805 (77.5%) underwent surgery for hip fractures thereafter (delayed surgery group). Early surgery was significantly associated with lower odds for hospital-acquired pneumonia (odds ratio, 0.42; 95% confidence interval, 0.25–0.69) and pressure ulcers (odds ratio, 0.56, 95%CI: 0.33–0.96, p = 0.035), but was not associated with 30-day mortality (odds ratio, 0.96; 95% confidence interval, 0.49–1.86) or pulmonary embolism (odds ratio, 1.62, 95%CI: 0.58–4.52, p = 0.357).ConclusionsThese results support current guidelines, which recommend early surgery for elderly hip fractures patients.

Risk factors for contra-lateral hip fracture in elderly patients with previous hip fracture

Introduction

Contra-lateral hip fractures in elderly patients with a previous hip fracture increase the incidence of complications and socioeconomic burden. The purpose of this study was to identify the risk factors that contribute to the occurrence of contra-lateral hip fracture in elderly patients.

Materials and methods

Among 1093 patients treated for a hip fracture, 47 patients sustained a contra-lateral hip fracture. These patients were compared with 141 patients with a unilateral hip fracture (controls).

Results

The incidence of contra-lateral hip fracture was 4.3% among the 1093 patients treated for a hip fracture at our institute. A contra-lateral hip fracture occurred within 2 years of initial fracture in 66%, and subsequently, the annual incidence rate decreased. A similar fracture pattern was noted in 70% of patients who sustained an intertrochanteric fracture. In terms of preoperative factors, respiratory disease (OR 2.57, P = 0.032) and visual impairment (OR 2.51, P = 0.012) were higher in patients with a contra-lateral hip fracture than in controls, and for postoperative factors, the proportions of patients with postoperative delirium (OR 2.91, P = 0.022), late onset of rehabilitation (OR 1.05, P = 0.023), and poor ambulatory status at 3 months (OR 1.34, P = 0.002) were also significantly higher in patients than in controls.

Conclusions

Postoperative delirium and underlying visual impairment and respiratory disease could be risk factors of contra-lateral fracture in elderly patients. Early and active rehabilitation after surgery is important to prevent the occurrence of contra-lateral hip fracture in the elderly.
