Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications. HIP ATTACK was an international, randomised, controlled trial done at 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were aged 45 years or older were eligible. Research personnel randomly assigned patients (1:1) through a central computerised randomisation system using randomly varying block sizes to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. The coprimary outcomes were mortality and a composite of major complications (ie, mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Patients, health-care providers, and study staff were aware of treatment assignment, but outcome adjudicators were masked to treatment allocation. Patients were analysed according to the intention-to-treat principle. This study is registered at ClinicalTrials.gov (NCT02027896). Between March 14, 2014, and May 24, 2019, 27 701 patients were screened, of whom 7780 were eligible. 2970 of these were enrolled and randomly assigned to receive accelerated surgery (n=1487) or standard care (n=1483). The median time from hip fracture diagnosis to surgery was 6 h (IQR 4–9) in the accelerated-surgery group and 24 h (10–42) in the standard-care group (p<0·0001). 140 (9%) patients assigned to accelerated surgery and 154 (10%) assigned to standard care died, with a hazard ratio (HR) of 0·91 (95% CI 0·72 to 1·14) and absolute risk reduction (ARR) of 1% (−1 to 3; p=0·40). Major complications occurred in 321 (22%) patients assigned to accelerated surgery and 331 (22%) assigned to standard care, with an HR of 0·97 (0·83 to 1·13) and an ARR of 1% (−2 to 4; p=0·71). Among patients with a hip fracture, accelerated surgery did not significantly lower the risk of mortality or a composite of major complications compared with standard care.

A randomized trial evaluating spinal as compared with general anesthesia for hip-fracture surgery in adults 50 years of age or older did not show superiority of spinal anesthesia with respect to a composite of death or an inability to walk unassisted at 60 days. Postoperative delirium occurred in similar percentages of patients in the two groups.

Background Perioperative neurocognitive dysfunction (PND), a prevalent complication affecting elderly surgical patients, poses substantial challenges to postoperative rehabilitation and long-term functional independence. Despite growing awareness of its clinical significance, current evidence regarding effective neuroprotective anesthetic strategies remains inconclusive. Where emerging evidence suggests opioid-free anesthesia (OFA) strategies could maintain analgesic efficacy while potentially attenuating opioid-associated neuroinflammatory mechanisms implicated in PND pathogenesis. This multicenter trial investigates the efficacy of OFA combined with ultrasound-guided iliofascial nerve block in mitigating PND among geriatric patients undergoing hip fracture surgery. Methods This multicenter, randomized controlled trial will enroll 348 patients, who will be randomly assigned to receive either OFA combined with iliofascial nerve block or opioid-based anesthesia (OBA) combined with iliofascial nerve block. All patients will undergo hip fracture surgery under general anesthesia with tracheal intubation. The primary outcome will be the change in composite neurocognitive scores, assessed through a battery of neuropsychological tests from baseline to 3 months postoperatively. Secondary outcomes include alterations in serum protein and inflammatory markers, extubation time, postoperative pain incidence, intraoperative hemodynamic stability, and postoperative recovery parameters. The safety profile of OFA in hip surgery will also be assessed. Discussion Effective prevention of PND is crucial for optimizing postoperative recovery and long-term functional outcomes in elderly patients. This trial aims to refine and optimize anesthesia management strategies to reduce the incidence of PND, improve postoperative quality of life, and ultimately enhance perioperative neurocognitive outcomes.

Ciprofol is a new intravenous sedative / anesthetic drug. In recent years, many clinical studies have also confirmed the sedative effect of ciprofol. However, more clinical research is still needed on its clinical application characteristics in special populations. The aim of this study was to compare the clinical effects of ciprofol and propofol in general anesthesia induction of elderly patients. 60 elderly (aged ≥ 75 years) patients underwent hip fracture surgery were randomly into two groups of a 1:1 ratio. Group C (ciprofol group): 0.3mg/kg ciprofol was infused. Group P (propofol group): 1.5mg/kg propofol was infused. The observation period was from the infusion of test drug to 5 min after endotracheal intubation. The primary outcomes included the incidence of severe hypotension and hypotension during the observation period. The secondary outcomes were as follows: the success rate of general anesthesia induction, the number of additional sedation, the time of loss of consciousness (LOC), Δ MAP, Δ HR, adverse events and the frequency of vasoactive drugs used. Finally, 60 subjects completed the study. Compared with Group P, the incidence of severe hypotension in Group C was lower (26.7% vs 53.3%, = 0.035), the incidence of hypotension was also lower (36.7% vs 63.3%, = 0.037), Δ MAP in Group C was significantly lower (31.4 ± 11.4 vs 39.6 ± 15.7, = 0.025), the frequency of ephedrine used and the incidence of injection pain in Group C were also significantly lower. Ciprofol showed similar efficacy to propofol when used for general anesthesia induction in elderly patients underwent hip fracture surgery and could maintain more stable blood pressure.

The impact of propofol-based total intravenous anaesthesia (TIVA) versus sevoflurane anaesthesia on renal function remains uncertain. We investigated the effect of anaesthetic type (propofol or sevoflurane) on renal function in elderly patients undergoing hip fracture surgery. In this randomised controlled trial, 66 elderly patients scheduled for hip fracture surgery were randomly allocated to either propofol or sevoflurane maintenance anaesthesia. The primary outcome was estimated glomerular filtration rate (eGFR) 1 hour postoperatively. The mean age was 70 yr and 53% were female. Compared with the sevoflurane group, the propofol group exhibited significantly higher eGFR levels at 1 hour postoperatively (mean [SD]: 89.4 [13.4] vs 80.1 [17.3] mL min 1.73m ; difference=9.34 mL min 1.73m ; 95% CI, 1.88 to 16.80 mL min 1.73m ; =0.017). In the secondary outcomes, the propofol group demonstrated significantly higher urine output during anaesthesia (difference=1.11 mL kg h ; 95% CI, 0.65 to 1.57 mL kg h ; <0.001), as well as significantly greater urinary sodium excretion both during anaesthesia (difference=2.88 mmol h ; 95% CI, 2.02 to 3.75 mmol h ; <0.001) and in the first 2 postoperative hours (difference=5.08 mmol h ; 95% CI, 3.20 to 6.97 mmol h ; <0.001). Plasma renin levels were significantly lower in the propofol group both during anaesthesia (difference=-93.60 mIU L ; 95% CI, -108.32 to -78.87 mIU L ; <0.001) and at 1 h postoperatively (difference=-27.90 mIU L ; 95% CI, -42.62 to -13.17 mIU L ; <0.001). All other secondary and safety outcomes were comparable between groups. After adjustment for baseline covariates, the analysis yielded consistent results. In subgroup analyses, there was no significant difference in eGFR at 1 hour postoperatively between the propofol and sevoflurane groups. Propofol-based TIVA was associated with higher eGFR at 1 hour postoperatively, along with increased urine output, greater urinary sodium excretion, and lower plasma renin levels during anaesthesia in elderly patients compared with sevoflurane anaesthesia. These findings warrant further investigation to determine their implications for long-term renal outcomes and intraoperative fluid management in this vulnerable population.

Background Hypotension during anaesthesia for hip fracture surgery is common. Recent data suggest that there is an association between the lowest intra-operative blood pressure and mortality, even when adjusted for co-morbidities. This is consistent with data derived from the wider surgical population, where magnitude and duration of hypotension are associated with mortality and peri-operative complications. However, there are no trial to data to support more aggressive blood pressure control. Methods/design We are conducting a three-centre, randomised, double-blinded pilot study in three hospitals in the United Kingdom. The sample size will be 75 patients (25 from each centre). Randomisation will be done using computer-generated concealed tables. Both participants and investigators will be blinded to group allocation. Participants will be aged >70 years, cognitively intact (Abbreviated Mental Test Score 7 or greater), able to give informed consent and admitted directly through the emergency department with a fractured neck of the femur requiring operative repair. Patients randomised to tight blood pressure control or avoidance of intra-operative hypotension will receive active treatment as required to maintain both of the following: systolic arterial blood pressure >80% of baseline pre-operative value and mean arterial pressure >75 mmHg throughout. All participants will receive standard hospital care, including spinal or general anaesthesia, at the discretion of the clinical team. The primary outcome is a composite of the presence or absence of defined cardiovascular, renal and delirium morbidity within 7 days of surgery (myocardial injury, stroke, acute kidney injury, delirium). Secondary endpoints will include the defined individual morbidities, mortality, early mobility and discharge to usual residence. Discussion This is a small-scale pilot study investigating the feasibility of a trial of tight intra-operative blood pressure control in a frail elderly patient group with known high morbidity and mortality. Positive findings will provide the basis for a larger-scale study. Trial registration ISRCTN Registry identifier: ISRCTN89812075 . Registered on 30 August 2016.

SummaryWe determined the prognostic value of nutritional status for outcome after hip fracture. Nutritional status was a strong independent prognostic factor for clinical outcome and 5-year mortality. Physical function showed incomplete recovery. Elderly care should focus on prevention already before hip fracture.PurposeTo determine the prognostic value of nutritional status in hip fracture patients for multiple clinical and functional outcomes over 6 months, and for new fractures and survival over 5 years post-fracture.MethodsWe included 152 well-characterized subjects (age 55+ years) with a hip fracture from a previously published randomized controlled trial. Nutritional status was appraised using the Mini Nutritional Assessment (MNA). Multivariable linear, logistic and Cox regression models were fitted, adjusted for age, sex, ASA score, group and additional prognostic covariates identified in backward regression models.ResultsAt baseline, impaired nutritional status was significantly associated with physical disability, depression, impaired cognition and lower quality of life. Prospective analyses showed that impaired baseline nutritional status was an independent prognostic factor for postoperative complications (OR 2.00, 95%CI 1.01–3.98, p = 0.047), discharge location from hospital (home vs. rehabilitation clinic, OR 0.41, 95%CI 0.18–0.98, p = 0.044), hospital readmission (OR 4.59, 95%CI 1.70–12.4, p = 0.003) and total length of hospital stay (HR of being discharged: 0.63, 96%CI 0.44–0.89, p = 0.008), as well as for 5-year mortality (HR 3.94, 95%CI 1.53–10.2, p = 0.005), but not for risk of new fractures (5y-HR 0.87, 95%CI 0.34–2.24, p = 0.769). Curves of physical disability over time showed that the three nutritional status categories followed almost parallel trajectories from baseline until 6 months after hip fracture, without complete recovery and even with further deterioration in malnourished subjects from 3 to 6 months post-fracture.ConclusionAs baselline nutritional status is a strong independent prognostic factor for clinical outcome after hip fracture, affecting even five-year survival, elderly health care should focus on prevention and identification of at-risk individuals already before hip fracture.

Mortality is increased in the year after a hip fracture, and strategies that improve the outcome are needed. This randomized, double-blind, placebo-controlled trial compared yearly intravenous zoledronic acid with placebo first administered within 90 days after surgical repair of a hip fracture in patients who were unable or unwilling to take oral bisphosphonates. Zoledronic acid was associated with a reduced relative risk of a new clinical fracture and a reduction in mortality from all causes. This trial compared yearly zoledronic acid with placebo after surgical repair of a hip fracture. Zoledronate was associated with a reduced relative risk of a new clinical fracture and a reduction in mortality from all causes. Hip fractures are associated with increased morbidity, functional decline, and death in older adults, as well as increased use of health care services. 1 , 2 Mortality is increased in the year after hip fracture, with reported rates of 15 to 25% and an estimated 9 excess deaths per 100 patients among women 70 years of age or older. 2 – 10 One source of the excess morbidity and cost incurred by patients with hip fractures is new osteoporotic fractures. Such fractures occur at a rate of 10.4 per 100 patients per year, which is 2.5 times as high as the rate in age-matched . . .

Disturbance of the sleep–wake cycle is a characteristic of delirium. In addition, changes in melatonin rhythm influence the circadian rhythm and are associated with delirium. We compared the effect of melatonin and placebo on the incidence and duration of delirium. We performed this multicentre, double-blind, randomized controlled trial between November 2008 and May 2012 in 1 academic and 2 nonacademic hospitals. Patients aged 65 years or older who were scheduled for acute hip surgery were eligible for inclusion. Patients received melatonin 3 mg or placebo in the evening for 5 consecutive days, starting within 24 hours after admission. The primary outcome was incidence of delirium within 8 days of admission. We also monitored the duration of delirium. A total of 452 patients were randomly assigned to the 2 study groups. We subsequently excluded 74 patients for whom the primary end point could not be measured or who had delirium before the second day of the study. After these postrandomization exclusions, data for 378 patients were included in the main analysis. The overall mean age was 84 years, 238 (63.0%) of the patients lived at home before admission, and 210 (55.6%) had cognitive impairment. We observed no effect of melatonin on the incidence of delirium: 55/186 (29.6%) in the melatonin group v. 49/192 (25.5%) in the placebo group; difference 4.1 (95% confidence interval −0.05 to 13.1) percentage points. There were no between-group differences in mortality or in cognitive or functional outcomes at 3-month follow-up. In this older population with hip fracture, treatment with melatonin did not reduce the incidence of delirium.

This trial compared a restrictive hemoglobin threshold with a liberal threshold for blood transfusion among hip-surgery patients with risk factors for CVD. The liberal strategy resulted in more transfusions and did not reduce death or inability to walk independently. In the United States, more than 17 million red-cell units are collected annually, and 15 million units are transfused. 1 Blood transfusions are frequently given to surgical patients and to the elderly. 2 , 3 Yet, the indications for postoperative transfusion have not been adequately evaluated and remain controversial. Most clinical trials have been small. 4 One adequately powered trial involving adults in intensive care units showed a nonsignificant decrease in 30-day mortality with a restrictive transfusion strategy, as compared with a liberal strategy (18.7% vs. 23.3%). 5 However, the effect of a restrictive approach on functional recovery or risk of myocardial infarction in patients . . .
