Abstract Background: Postoperative cognitive dysfunction (POCD) is a great problem for anesthetized subjects and is associated with poor short- and long-term outcomes. We explored promising predictors for POCD in elderly patients after hip fracture surgery. Methods: Elderly subjects (aged ≥65 years) undergoing surgery for hip fracture were consecutively recruited. Neuropsychological assessments were performed 1 day preoperatively (baseline) and 7 days postoperatively, and POCD was defined using the ‘Z scores’ method. Clinical data and laboratory tests were compared between patients with and without POCD development. Binary univariate and multivariate logistic regression analyses were conducted for risk factor assessment. Receiver operating characteristic (ROC) curve analysis was performed to investigate the predictive value of malondialdehyde (MDA) on postoperative day 1 (POD1) for POCD. Results: A total of 198 patients were finally enrolled in the analysis and 51 patients exhibited POCD within 7 postoperative days, with an incidence rate of 25.8%. MDA expression on POD1 (OR: 1.12, 95%CI: 1.03–1.23, P=0.017) was the only independent risk factor for POCD according to the final multivariate logistic regression analysis. ROC curve analysis indicated that MDA on POD1 was a predictor for POCD, with an area under the curve (AUC) of 0.683 and 95%CI of 0.590–0.775 (P<0.001). Conclusions: In conclusion, we demonstrated that MDA on POD1 was an independent risk factor for POCD in elderly subjects undergoing hip fracture surgery.

Mortality following hip fracture surgery is high, with 7% mortality at 30 days and 18% at 120 days. This reflects the pre-existing poor health of some of those who present with such an injury. Large studies have demonstrated that delayed surgery is an independent risk factor for mortality. The British Orthopaedic Association (BOA) recommends that hip fracture surgery be undertaken within 48 hours in all those medically fit. Payment by Results (PbR) was introduced in July 2000 in the NHS Plan, linking the allocation of funds to hospitals to the activity undertaken. This was designed to 'provide a transparent, rules-based system […] which would reward efficiency, support patient choice and diversity and encourage activity for sustainable waiting time reductions'.

Background: Postoperative delirium (POD), a neurobehavioral syndrome induced by dysfunction of neural activity, is a common and serious complication. This current study aimed to investigate independent predictors for POD in elderly subjects after total joint arthroplasty (TJA). Methods: Eligible elderly patients (≥65 years) who underwent elective unilateral primary hip or knee arthroplasty under epidural anesthesia from October 2016 to January 2019 were consecutively enrolled. POD was diagnosed following the guidance of the 5th edition of Diagnostic and Statistical Manual of Mental Disorders, (DSM V, 2013). The relative change in serum Alb (ΔAlb) was defined as the absolute value of (preoperative Alb value– nadir value within postoperative day 2)/preoperative Alb ×100%. The predictive value of ΔAlb for POD was evaluated by receiver operating characteristic (ROC) curve analysis. Univariate and multivariate logistic regression analyses were used for evaluating risk factors for POD. Results: A total of 328 patients were enrolled in the analysis, of which 68 (20.7%, 68/328) patients developed POD within postoperative 7 days. ΔAlb was an effective predictor for POD with an area under the curve (AUC) of 0.821, a sensitivity of 76.15% and a specificity of 70.59%, respectively (P<0.001). Univariate and multivariate logistic regression analyses indicated that ΔAlb was the only independent risk factor for POD (OR: 2.43, 95%CI: 1.17–4.86, P=0.015). Conclusions: ΔAlb was an independent risk factor for POD in elderly subjects after TJA.

Abstract Background This study aimed to investigate the incidence and risk factors of postoperative urinary retention (POUR) among elderly patients who underwent hip fracture surgery and to evaluate the effect of indwelling catheterization on the occurrence of POUR. Materials and methods From January 2012 to January 2015, consecutive patients aged over 70 years who underwent hip fracture surgery were enrolled in this study. All patients underwent indwelling catheterization due to voiding difficulty upon admission. Demographic data, perioperative variables, and postoperative duration of patient-controlled analgesia and indwelling catheterization, postoperative complications, and mortality were collected. The incidence of POUR was investigated, and the risk factors related to POUR were analyzed using a logistic regression analysis. The cutoff value for the timing of catheter removal was determined using receiver operating characteristic (ROC) curve analysis. Results POUR developed in 68 patients (31.8%) of the 214 patients. Of these, 24 (35.3%) were male. The indwelling catheter was left in place for an average of 3.4 days (range, 0–7 days) postoperatively. A significant difference was noted in gender and duration of indwelling catheterization between patients with POUR and without. The cutoff value for the timing of catheter removal as determined by ROC curve analysis was 3.5 postoperative day with 51.4% sensitivity and 71.5% specificity. Multiple logistic regression revealed that the duration of the indwelling catheter [odds ratios (OR), 0.31; p = 0.016)] and male gender (OR, 2.22; p = 0.014) were independent risk factors related to the occurrence of POUR. Conclusions The significant risk factors of POUR among elderly patients undergoing hip fracture surgery were early indwelling catheter removal and male gender. Therefore, early removal of indwelling catheter in elderly patients following hip fracture surgery may increase the risk of POUR, especially in male patients.

Introduction: End-stage renal failure (ESRF) with its associated comorbidities increase postoperative mortality in hip fracture patients. This study investigated the association of ESRF with various comorbidities in patients on dialysis and assessed rates ESRF as an independent risk factor for all-cause postoperative 1- year mortality rates. Methods: This was a retrospective cohort study on patients aged 55 years and older who underwent their first nonpathological, low-energy hip fracture surgery at an Asian tertiary hospital from June 2007 to 2012. Patients were identified as cases with ESRF on dialysis (study group) or non-ESRF patients (controls). Various comorbidity factors and postoperative 1-year mortality status were obtained from institutional electronic medical records. Univariate and multivariate logistic regression were used to identify significant risk factors for all-cause, 1-year mortality. Results: With no loss to follow-up, the 1-year postoperative mortality rate was 19.6% for the 46 patients with ESRF on dialysis and 8.4% for non-ESRF controls ( P = .028). Fisher exact test showed that hypertension, ischemic heart disease (IHD), diabetes mellitus (DM), anemia, cerebrovascular disease, and vascular disease were significantly associated with ESRF ( P < .05). Multivariable logistic regression analysis identified ESRF (adjusted odds ratio[AOR] = 2.85, P = .021), cancer (AOR = 3.04, P = .003), IHD (AOR = 2.07, P = .020), DM (AOR = 2.03, P = .022), and age (AOR = 1.08, P <.0001) as independent risk factors for 1-year mortality following hip fracture surgery. The area under the receiver–operating characteristic curve (95% confidence interval) for the multivariable predictor of 1-year mortality was 0.75 (0.60-0.82). Conclusions: Although associated with multiple comorbidities, ESRF was found to be independently predictive of 1-year mortality in patients undergoing hip fracture surgery, second to cancer in terms of magnitude of risk posed. As ESRF is a negative prognostic factor for 1-year mortality after hip fracture surgery, its importance should be recognized with implications on preoperative counseling to patients about the increased risk and implications on fracture prevention.

Introduction: Intertrochanteric hip fractures are a common injury treated by orthopedic surgeons and the incidence rate is rising. Preoperative depression is a known risk factor for postoperative complications in orthopaedic surgery, however its effects on outcomes after geriatric hip fractures is relatively unknown. The purpose of this study was to investigate the relationship between preoperative depression and potential complications following open reduction internal fixation (ORIF) and intramedullary nailing (IMN) of geriatric hip fractures. Methods: In this retrospective study, the Truven Marketscan claims database was used to identify patients over age 65 who underwent ORIF or IMN for a hip fracture from January 2009 to December 2019. Patient characteristics, such as medical comorbidities, were collected and from that 2 cohorts were established (one with and one without depression). Chi-squared and multivariate analysis was performed to investigate the association between preoperative depression and common postoperative complications following intertrochanteric hip fracture surgery. Results: In total, 78,435 patients were identified for analysis. In those patients with preoperative depression, the complications associated with the greatest increased odds after undergoing ORIF were surgical site infections (OR 1.32; CI 1.23-1.44), ED visit for pain (OR 1.27; CI 1.16-1.39), wound complications (OR 1.26; CI 1.14-1.35), and non-union (OR 1.25; CI 1.17-1.33). In the patients with preoperative depression undergoing IMN, the complications associated with the greatest increased odds after were surgical site infections (OR 1.37; CI 1.31- 1.45), ED visit for pain (OR 1.31; CI 1.19-1.44), wound complications (OR 1.23; CI 1.10-1.39), and pneumonia (OR 1.22; CI 1.10-1.31). Conclusions: Preoperative depression in patients undergoing hip fracture surgery is associated with increased complications. Recognizing a patients’ preoperative depression diagnosis can allow physicians to adapt perioperative and postoperative surveillance protocols for these higher risk patients. Further studies are warranted to investigate the degree to which depression is a modifiable risk factor

Abstract Background This study aimed to explore the preoperative risk factors related to blood transfusion after hip fracture operations and to establish a nomogram prediction model. The application of this model will likely reduce unnecessary transfusions and avoid wasting blood products. Methods This was a retrospective analysis of all patients undergoing hip fracture surgery from January 2013 to January 2020. Univariate and multivariate logistic regression analyses were used to evaluate the association between preoperative risk factors and blood transfusion after hip fracture operations. Finally, the risk factors obtained from the multivariate regression analysis were used to establish the nomogram model. The validation of the nomogram was assessed by the concordance index (C-index), the receiver operating characteristic (ROC) curve, decision curve analysis (DCA), and calibration curves. Results A total of 820 patients were included in the present study for evaluation. Multivariate logistic regression analysis demonstrated that low preoperative hemoglobin (Hb), general anesthesia (GA), non-use of tranexamic acid (TXA), and older age were independent risk factors for blood transfusion after hip fracture operation. The C-index of this model was 0.86 (95% CI, 0.83–0.89). Internal validation proved the nomogram model’s adequacy and accuracy, and the results showed that the predicted value agreed well with the actual values. Conclusions A nomogram model was developed based on independent risk factors for blood transfusion after hip fracture surgery. Preoperative intervention can effectively reduce the incidence of blood transfusion after hip fracture operations.
