Abstract:

Background Postoperative delirium (POD) is a common and debilitating complication in elderly hip fracture patients, associated with significant clinical and functional consequences. Early identification of risk factors, such as cognitive impairment and vitamin D deficiency, is essential to mitigate its impact. However, preoperative screening practices are often inconsistent. This quality improvement initiative aimed to assess and improve compliance with early confusion and vitamin D screening in elderly hip fracture patients, with the goal of facilitating timely interventions to reduce the risk of POD. Methods A two-cycle audit was conducted in the Trauma and Orthopaedics Department at Royal Shrewsbury Hospital. The first cycle (April-June 2023) assessed baseline compliance with confusion (Abbreviated Mental Test Score (AMTS)) and vitamin D screening within 24 hours of admission. Identified barriers informed an intervention consisting of educational sessions, visual prompts, and checklist integration. The second cycle (August-October 2023) evaluated the impact of these measures. Compliance rates, timing of
assessments, and prevalence of abnormal biochemical and cognitive screening results were analyzed using Fisher's exact test (p < 0.05). Results Baseline compliance with screening was 27 patients (27%) out of 100, with primary barriers including lack of awareness and logistical challenges. Post-intervention compliance improved significantly for 54 patients (52.4%) out of 103 (p = 0.0003). Screening timeliness also increased, with 45 patients (83.33%) out of 54 screenings completed within 24 hours in cycle 2 compared to 14 patients (51.85%) out of 27 in cycle 1 (p = 0.0039). Biochemical analysis revealed persistently high rates of vitamin D deficiency, underscoring the need for early detection. AMTS scores correlated with abnormal confusion screens but highlighted limitations in cognitive-only assessments. Conclusion This quality improvement (QI) initiative demonstrated the efficacy of targeted interventions in improving screening compliance for confusion and vitamin D deficiency in elderly hip fracture patients. The findings advocate for integrating proactive, dual-focused screening protocols into clinical workflows to address modifiable risk factors for POD. Future research should explore the long-term impact of such measures on POD incidence, recovery trajectories, and functional outcomes while emphasizing the need
for sustained adherence to screening protocols.

Abstract:
BACKGROUND: Thin lateral femoral wall has been investigated as a sign of instability in trochanteric hip fractures, necessitating lateral wall reconstruction or the use of a cephalomedullary nail (CMN). Various cut-off values have been proposed to guide implant choice. This review aims to determine the clinical significance of the lateral femoral wall thickness (LWT) in trochanteric hip fractures and identify an optimal cut-off value for increased risk of lateral wall (LW) fracture when using Dynamic Hip Screw (DHS). METHODS: A comprehensive search was conducted in databases including Medline, Embase, and the Cochrane library up to July 2023. A predefined strategy was employed, with 5 eligible studies critically appraised using the methodological index for non-randomized studies (MINORS) criteria. Outcomes assessed encompassed the standardised mean difference (SMD) of LWT between the LW fracture and non LW fracture groups, aggregate LWT mean in LW fracture group, and the relation between AO/OTA fracture type with LW fracture utilising the chi-square test. RESULTS: Among 481 patients from 5 studies, 112 experienced LW fractures, while 369 did not postoperatively. Analysis indicated a significantly lower LWT in the LW fracture group (SMD -1.13, I2 = 41.3%, p = 0.146). The mean LWT in the LW fracture group was 18.2 mm, with a 95% confidence interval of 17.29-19.10 mm. CONCLUSIONS: A preoperative thin lateral femoral wall is a critical predictor of fixation failure and suboptimal functional outcomes when using a DHS. Thorough evaluation of pre- and intraoperative x-rays is essential. CMN is recommended over DHS in cases with LWT measurements <19 mm.

Abstract:
Perioperative tranexamic acid use is a popular choice among many surgeons for reducing surgical blood loss and its sequelae. While there is evidence in the literature that tranexamic acid use is effective in reducing blood loss in surgery for patients with hip fractures, there is less information on whether it leads to thromboembolic complications. We undertook a retrospective study in patients with hip fractures at two local hospitals to investigate if there was an increased risk of venous thromboembolism in patients who received tranexamic acid, and whether it reduced perioperative blood loss and the need for transfusion. We found that tranexamic acid used in patients undergoing hip fracture surgery reduced the drop in postoperative haemoglobin and the need for postoperative blood transfusion but was not associated with an increased risk of venous thromboembolism.
