Aims. Hip fractures are some of the most common fractures encountered in orthopaedic practice. We aimed to identify whether perioperative hypotension is a predictor of 30-day mortality, and to stratify patient groups that would benefit from closer monitoring and early intervention. While there is literature on intraoperative blood pressure, there are limited studies examining pre- and postoperative blood pressure. Methods. We conducted a prospective observational cohort study over a one-year period from December 2021 to December 2022. Patient demographic details, biochemical results, and haemodynamic observations were taken from electronic medical records. Statistical analysis was conducted with the Cox proportional hazards model, and the effects of independent variables estimated with the Wald statistic. Kaplan-Meier survival curves were estimated with the log-rank test. Results. A total of 528 patients were identified as suitable for inclusion. On multivariate analysis, postoperative hypotension of a systolic blood pressure (SBP) < 90 mmHg two to 24 hours after surgery showed an increased hazard ratio (HR) for 30-day mortality (HR 4.6 (95% confidence interval (CI) 2.3 to 8.9); p < 0.001) and was an independent risk factor accounting for sex (HR 2.7 (95% CI 1.4 to 5.2); p = 0.003), age (HR 1.1 (95% CI 1.0 to 1.1); p = 0.016), American Society of Anesthesiologists grade (HR 2.7 (95% CI 1.5 to 4.6); p < 0.001), time to theatre > 24 hours (HR 2.1 (95% CI 1.1 to 4.2); p = 0.025), and preoperative anaemia (HR 2.3 (95% CI 1.0 to 5.2); p = 0.043). A preoperative SBP of < 120 mmHg was close to achieving significance (HR 1.9 (95% CI 0.99 to 3.6); p = 0.052). Conclusion. Our study is the first to demonstrate that postoperative hypotension within the first 24 hours is an independent risk factor for 30-day mortality after hip fracture surgery. Clinicians should recognize patients who have a SBP of < 90 mmHg in the early postoperative period, and be aware of the increased mortality risk in this specific cohort who may benefit from a closer level of monitoring and early intervention.

Aims. This study aims to assess the feasibility of conducting a pragmatic, multicentre randomized controlled trial (RCT) to test the clinical and cost-effectiveness of an informal caregiver training programme to support the recovery of people following hip fracture surgery. Methods. This will be a mixed-methods feasibility RCT, recruiting 60 patients following hip fracture surgery and their informal caregivers. Patients will be randomized to usual NHS care, versus usual NHS care plus a caregiver-patient dyad training programme (HIP HELPER). This programme will comprise of three, one-hour, one-to-one training sessions for the patient and caregiver, delivered by a nurse, physiotherapist, or occupational therapist. Training will be delivered in the hospital setting pre-patient discharge. It will include practical skills for rehabilitation such as: transfers and walking; recovery goal setting and expectations; pacing and stress management techniques; and introduction to the HIP HELPER Caregiver Workbook, which provides information on recovery, exercises, worksheets, and goal-setting plans to facilitate a ‘good’ recovery. After discharge, patients and caregivers will be supported in delivering rehabilitation through three telephone coaching sessions. Data, collected at baseline and four months post-randomization, will include: screening logs, intervention logs, fidelity checklists, quality assurance monitoring visit data, and clinical outcomes assessing quality of life, physical, emotional, adverse events, and resource use outcomes. The acceptability of the study intervention and RCT design will be explored through qualitative methods with 20 participants (patients and informal caregivers) and 12 health professionals. Discussion. A multicentre recruitment approach will provide greater external validity across population characteristics in England. The mixed-methods approach will permit in-depth examination of the intervention and trial design parameters. The findings will inform whether and how a definitive trial may be undertaken to test the effectiveness of this caregiver intervention for patients after hip fracture surgery.

Aims. This study aimed to describe preoperative waiting times for surgery in hip fracture patients in Norway, and analyze factors affecting waiting time and potential negative consequences of prolonged waiting time. Methods. Overall, 37,708 hip fractures in the Norwegian Hip Fracture Register from January 2014 to December 2018 were linked with data in the Norwegian Patient Registry. Hospitals treating hip fractures were characterized according to their hip fracture care. Waiting time (hours from admission to start of surgery), surgery within regular working hours, and surgery on the day of or on the day after admission, i.e. ‘expedited surgery’ were estimated. Results. Mean waiting time was 22.6 hours (SD 20.7); 36,652 patients (97.2%) waited less than three days (< 72 hours), and 27,527 of the patients (73%) were operated within regular working hours (08:00 to 16:00). Expedited surgery was given to 31,675 of patients (84%), and of these, 19,985 (53%) were treated during regular working hours. Patients classified as American Society of Anesthesiologists (ASA) classes 4 and 5 were more likely to have surgery within regular working hours (odds ratio (OR) 1.59; p < 0.001), and less likely to receive expedited surgery than ASA 1 patients (OR 0.29; p < 0.001). Low-volume hospitals treated a larger proportion of patients during regular working hours than high volume hospitals (OR 1.26; p < 0.001). High-volume hospitals had less expedited surgery and significantly longer waiting times than low and intermediate-low volume hospitals. Higher ASA classes and Charlson Comorbidity Index increased waiting time. Patients not receiving expedited surgery had higher 30-day and one-year mortality rates (OR 1.19; p < 0.001) and OR 1.13; p < 0.001), respectively. Conclusion. There is inequality in waiting time for hip fracture treatment in Norway. Variations in waiting time from admission to hip fracture surgery depended on both patient and hospital factors. Not receiving expedited surgery was associated with increased 30-day and one-year mortality rates. Cite this article: Bone Jt Open 2021;2(9):710–720

Aims

To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture.

Prolonged bedrest in hospitalized patients is a major risk factor for venous thromboembolism (VTE), especially in high risk patients with hip fracture. Thrombelastography (TEG) is a whole blood viscoelastic hemostatic assay with evidence that an elevated maximal amplitude (MA), a measure of clot strength, is predictive of VTE in orthopaedic trauma patients. The objective of this study was to compare the TEG MA parameter between patients with hip fracture who were more mobile post-operatively and discharged from hospital early to patients with hip fracture with reduced mobility and prolonged hospitalizations post-operatively. In this prospective cohort study, TEG analysis was performed in patients with hip fracture every 24-hours from admission until post-operative day (POD) 5, then at 2- and 6-weeks post-operatively. Hypercoagulability was defined by MA > 65. Patients were divided into an early (within 5-day) and late (after 5-day) discharge group, inpatient at 2-weeks group, and discharge to MSK rehabilitation (MSK rehab), and long term care (LTC) groups. Two-sample t-test was used to analyze differences in MA between the early discharge and less mobile groups. All statistical tests were two-sided, and p-values < 0.05 were considered statistically significant. In total, 121 patients with a median age of 81.0 were included. Patients in the early discharge group (n=15) were younger (median age 64.0) and more likely to ambulate without gait aids pre-injury (86.7%) compared to patients in the late discharge group (n=105), inpatients at 2-weeks (n=48), discharged to MSK rehab (n=30), and LTC (n=20). At two weeks post-operative, the early discharge group was significantly less hypercoagulable (MA=68.9, SD 3.0) compared to patients in the other four groups. At 6-weeks post-operative, the early discharge group was the only group to demonstrate a trend towards mean MA below the MA > 65 hypercoagulable threshold (MA=64.4, p=0.45). Symptomatic VTE events were detected in three patients (2.5%) post-operatively. All three patients had hospitalizations longer than five days after surgery. In conclusion, our analysis of hypercoagulability secondary to reduced post-operative mobility demonstrates that patients with hip fracture who were able to mobilize independently sooner after hip fracture surgery, have a reduced peak hypercoagulable state. In addition, there is a trend towards earlier return to normal coagulation status as determined by the TEG MA parameter. Post-operative mobility status may play a role in determining individualized duration of thromboprophylaxis following hip fracture surgery. Future studies comparing TEG to clinically validated mobility tools may more closely evaluate the contribution of venous stasis due to reduced mobility on hypercoagulation following hip fracture surgery

Aims. This study explores the reported rate of surgical site infection (SSI) after hip fracture surgery in published studies concerning patients treated in the UK. Methods. Studies were included if they reported on SSI after any type of surgical treatment for hip fracture. Each study required a minimum of 30 days follow-up and 100 patients. Meta-analysis was undertaken using a random effects model. Heterogeneity was expressed using the I. 2. statistic. Risk of bias was assessed using a modified Newcastle-Ottawa Scale (NOS) system. Results. There were 20 studies reporting data from 88,615 patients. Most were retrospective cohort studies from single centres. The pooled incidence was 2.1% (95% confidence interval (CI) 1.54% to 2.62%) across ‘all types’ of hip fracture surgery. When analyzed by operation type, the SSI incidences were: hemiarthroplasty 2.87% (95% CI 1.99% to 3.75%) and sliding hip screw 1.35% (95% CI 0.78% to 1.93%). There was considerable variation in definition of infection used, as well as considerable risk of bias, particularly as few studies actively screened participants for SSI. Conclusion. Synthesis of published estimates of infection yield a rate higher than that seen in national surveillance procedures. Biases noted in all studies would trend towards an underestimate, largely due to inadequate follow-up

The Nottingham Hip Fracture Score (NHFS) was developed in 2007 as a predictor of 30-day mortality after hip fracture surgery following a neck of femur fracture. The National Hip Fracture Database is the standard used which calculated their own score using national data. The NHF score for 30-day mortality was calculated for 50 patients presenting with a fractured neck femur injury between January 2020 to March 2020. A score <5 was classified as low risk and >/=5 as high risk. Aim was to assess the accuracy in calculating the Nottingham Hip Fracture Score against the National Hip Fracture Database. To explore whether it should it be routinely included during initial assessment to aid clinical management?. There was an increase in the number of mortalities observed in patients who belonged to the high-risk group (>=5) compared to the low risk group. COVID-19 positive patients had worse outcomes with average 30-day mortality of 6.78 compared to the average of 6.06. GEH NHF score per month showed significant accuracy against the NHFD scores. The identification of high-risk groups from their NHF score can allow for targeted optimisations and elucidation of risk factors easily gathered at the point of hospitalisation. The NHFS is a valuable tool and useful predictor to stratify the risk of 30-day mortality and 1-year mortality after hip fracture surgery. Inclusion of the score should be considered as mandatory Trust policy for neck of femur fracture patients to aid clinical management and improve patient safety overall

Objectives. As per NICE guidance, one of the cornerstones of management of AKI is risk assessment. Aim of the audit is to identify the potential risk factors for postoperative AKI in hip fracture patients. Design and Methods. Using local NOF registration data, Patient details were selected using inclusion and exclusion criteria. Electronic records of patients were assessed retrospectively including blood results, radiological investigations, clinical documentation and drug chart. Inclusion Criteria: All patients > 50 years old with NOF fractures underwent operative management from January 2022 to June 2022 Exclusion Criteria: 1- Pathological fractures. 2- Non-operative management. 3- Died directly postoperative. Results. 250 patients underwent hip fracture surgery at our hospital in 6 months (January 2022-June 2022) (Cemented Procedures were 133 (53 %) while Fixation procedures were 117 (47%)). Female patients were 174 (70%), and male were 76 patients. Average age was 83.4 years and number of operations done over Weekend (Friday-Sunday) = 123 (49%). The incidence of Postoperative AKI was 56 (22.4%). Forty-five from fifty-six cases were stage 1 (80.4%) while 7 cases (12.5%) were stage 2. The studied risk factors for Postoperative AKI were: cemented procedures (61% of postoperative AKI incidence), female Gender (66%), time from admission to operation (>24 hours =33 %), day of operation (operations done Friday/Saturday/Sunday = 55%) and Postoperative antibiotics (71%). Conclusion. We need strategies to reduce incidence of postoperative AKI like: AKI alert on laboratory results, IV fluid prescription preoperative since arrival of patients to ED, avoid/stop nephrotoxic medications on admission, regular review of postoperative U&Es and fluid balance especially in high-risk patients, increase nursing staff and junior doctors on wards over weekends and we need to review our policy of giving postoperative IV antibiotics

Objectives. The National Hip Fracture Database (NHFD) publishes hospital-level risk-adjusted mortality rates following hip fracture surgery in England, Wales and Northern Ireland. The performance of the risk model used by the NHFD was compared with the widely-used Nottingham Hip Fracture Score. Methods. Data from 94 hospitals on patients aged 60 to 110 who had hip fracture surgery between May 2013 and July 2013 were analysed. Data were linked to the Office for National Statistics (ONS) death register to calculate the 30-day mortality rate. Risk of death was predicted for each patient using the NHFD and Nottingham models in a development dataset using logistic regression to define the models’ coefficients. This was followed by testing the performance of these refined models in a second validation dataset. Results. The 30-day mortality rate was 5.36% in the validation dataset (n = 3861), slightly lower than the 6.40% in the development dataset (n = 4044). The NHFD and Nottingham models showed a slightly lower discrimination in the validation dataset compared with the development dataset, but both still displayed moderate discriminative power (c-statistic for NHFD = 0.71, 95% confidence interval (CI) 0.67 to 0.74; Nottingham model = 0.70, 95% CI 0.68 to 0.75). Both models defined similar ranges of predicted mortality risk (1% to 18%) in assessment of calibration. Conclusions. Both models have limitations in predicting mortality for individual patients after hip fracture surgery, but the NHFD risk adjustment model performed as well as the widely-used Nottingham prognostic tool and is therefore a reasonable alternative for risk adjustment in the United Kingdom hip fracture population.

Aims. To develop a core outcome set of measurements from postoperative radiographs that can be used to assess technical skill in performing dynamic hip screw (DHS) and hemiarthroplasty, and to validate these against Van der Vleuten’s criteria for effective assessment. Methods. A Delphi exercise was undertaken at a regional major trauma centre to identify candidate measurement items. The feasibility of taking these measurements was tested by two of the authors (HKJ, GTRP). Validity and reliability were examined using the radiographs of operations performed by orthopaedic resident participants (n = 28) of a multicentre randomized controlled educational trial (ISRCTN20431944). Trainees were divided into novice and intermediate groups, defined as having performed < ten or ≥ ten cases each for DHS and hemiarthroplasty at baseline. The procedure-based assessment (PBA) global rating score was assumed as the gold standard assessment for the purposes of concurrent validity. Intra- and inter-rater reliability testing were performed on a random subset of 25 cases. Results. In total, 327 DHS and 248 hemiarthroplasty procedures were performed by 28 postgraduate year (PGY) 3 to 5 orthopaedic trainees during the 2014 to 2015 surgical training year at nine NHS hospitals in the West Midlands, UK. Overall, 109 PBAs were completed for DHS and 80 for hemiarthroplasty. Expert consensus identified four ‘final product analysis’ (FPA) radiological parameters of technical success for DHS: tip-apex distance (TAD); lag screw position in the femoral head; flushness of the plate against the lateral femoral cortex; and eight-cortex hold of the plate screws. Three parameters were identified for hemiarthroplasty: leg length discrepancy; femoral stem alignment; and femoral offset. Face validity, content validity, and feasibility were excellent. For all measurements, performance was better in the intermediate compared with the novice group, and this was statistically significant for TAD (p < 0.001) and femoral stem alignment (p = 0.023). Concurrent validity was poor when measured against global PBA score. This may be explained by the fact that they are measuring difference facets of competence. Intra-and inter-rater reliability were excellent for TAD, moderate for lag screw position (DHS), and moderate for leg length discrepancy (hemiarthroplasty). Use of a large multicentre dataset suggests good generalizability of the results to other settings. Assessment using FPA was time- and cost-effective compared with PBA. Conclusion. Final product analysis using post-implantation radiographs to measure technical skill in hip fracture surgery is feasible, valid, reliable, and cost-effective. It can complement traditional workplace-based assessment for measuring performance in the real-world operating room . It may have particular utility in competency-based training frameworks and for assessing skill transfer from the simulated to live operating theatre.

Introduction. Following National patient safety alert on cement use in hip fracture surgery, we investigated the incidence and pattern of 72 hours peri-operative mortality after hip fracture surgery in a District General Hospital. Methods. We reviewed all patients who had hip fracture surgery between 2005-April, 2010. We recorded demographic variables, type of fracture, implant used, medical co-morbidity, seniority of operating surgeon and anaesthetist, peri-operative haemodynamic status, time and cause of death. Results. Over a 64 month period 15 cases were identified. Peri-operative death (PAD) was 1% (15/1402). 4/15 patients died intra-operatively. PAD was highest following Exeter Trauma Stem (ETS) implantation (5/85, 6%) and nil following Bipolar arthroplasty, Austin-Moore arthroplasty (AMA) or Cannulated screw fixation. PAD following total hip arthroplasty was 4% (1/25), Thompson's hemi-arthroplasty 2% (3/191), and Dynamic Hip Screw fixation 1% (6/695). Overall mortality after cemented implant was 2%. ETS implantation led to significantly increased peri-operative mortality compared to AMA (p=0.004). Operations were performed by both trainees (12) and Consultants (3). Both trainees (9) and Consultants (6) anaesthetised the patients. None of the patients belonged to ASA I or II (ASA III 6 and IV 9). All patients had significant cardio-vascular or pulmonary co-morbidity (Ca Lung 2, pulmonary fibrosis 1, end stage COAD 1, AF 6). Cemented implant insertion was followed by immediate haemodynamic collapse and death in 4/15, intra-operative haemodynamic instability in 1/15 and peri-operative instability in 5/15. Post-mortem was performed in 5/15: 2/5 were Pulmonary Embolism (PE), 2/5 bronchopneumonia and 1/5 Myocardial infarction (MI). 4/15 had suspected MI and 1/15 suspected PE. Conclusion. There was 1% risk of peri-operative death after hip fracture surgery. This risk was increased following cemented hemiarthroplasty and highest after ETS implantation. Risk was exacerbated in patients with pre-existing cardiovascular morbidity and independent of the seniority of the surgeon or the anaesthetist

The international literature base demonstrates that individuals living with diabetes mellitus (DM) are at increased risk of mortality and post-operative complications following hip fracture surgery (HFS) than non-diabetics. Studies investigating databases in American, European or Asiatic populations highlight the impact geography can have on the resultant investigation. We aim to quantify the impact DM has on HFS patients in a single university hospital. The HIPE dataset of fragility fractures occurring in Galway University Hospital from 2014–2016 were analysed and cross referenced with hospital laboratory and public databases. A database of 759 individuals was created including 515 females and 237 males, with a mean age of 78+/−12.2 years, of which 110 patients had DM. The patient length-of-stay (PLOS) was comparable in all groups with patient age being the primary influencing factor. An extended PLOS correlated with an increased long-term mortality. A trend toward increased occurrence of sub-trochanteric fractures was observed in diabetics with fewer periprosthetic and intertrochanteric fractures. Patients with DM had a significant increased risk of post-operative mortality compared to non-diabetics. Males with DM where at a greater risk of death after HFS [HR 2.29, 95% CI 1.26–4.17. p=0.006] than females with DM [HR 1.69, 95% CI 0.99–2.91. p=0.056]. The presence of DM did not directly impact a patient's PLOS or increase the need for a re-operation. DM is associated with increased post-operative patient mortality and may influence the anatomical fracture pattern. This observation will support further investigation into the mechanical and biochemical changes occurring in the femur in individuals living with DM

Currently there is an elevated public awareness of the consequences of nosocomial infection, of which, 14.5% is due to surgical site infection (SSI). Hip fracture patients are at increased risk of SSI due to their age related poor medical health, immune response impairments and decreased capacity of wound healing. Superficial SSI following hip fracture surgery can affect up to 16.9% with deep infection affecting 3.7%. Deep infection represents a major complication, from which hip fracture patients are 4.5 times less likely to survive to discharge and carries a 50% mortality at 1 year, compared to 33% without infection. Treatment requires a prolonged hospital stay, additional diagnostic testing, antibiotic therapy and surgery, resulting in the total cost of treating deep infection to be more than double that of non-infected hip fracture surgery. Wound closure aims to accurately appose the skin edges thereby promoting rapid healing and restoration of the protective dermal barrier. Failure to provide accurate skin apposition can result in delayed wound healing which has been shown to have a 3 fold risk of developing late infection. Importantly, delayed wound healing is reflected by prolonged wound ooze. We hypothesized that skin closure via sutures is better at achieving skin edge apposition than wounds closed with staples, providing more rapid wound healing. We compared staples and sutures for wound closure in hip fracture patients by using ooze duration as an outcome measure for wound healing. Duration of wound ooze was recorded in 170 patients. 65 wounds, closed with sutures, had an average duration of ooze of 1.82 days. 105 wounds, closed with staples, had an average duration of ooze of 4.97 days. This study suggests that sutures are superior to staples with regard to early wound healing in hip fracture patients

Introduction Recent changes in the management of hip fracture surgery patients may have resulted in changes in the epidemiology of venous thromboembolism (VTE). We aimed to determine the incidence of and predictive risk factors for symptomatic VTE and mortality, and the use of VTE prophylaxis, in hip fracture surgery patients. Methods Hip fracture surgery patients were enrolled in 525 hospitals in France between October 1 and November 30, 2002 in this prospective, multicenter, epidemiological study. VTE was assessed by a critical events committee at 3 months. Risk factors were identified using logistic regression. Results Data were from 6860 (97%) of 7019 enrolled patients. Median age was 82 years and 76% were women. 47% were femoral neck and 53% trochanteric or subtrochanteric fractures. All were operated on (osteosynthesis 57%, half prosthesis 35% and THR 8%). Prophylaxis with a low-molecular-weight heparin (LMWH) was administered perioperatively in 97.6% and for at least four weeks in 69.5% (median prophylaxis duration: 6 weeks). The rate of symptomatic VTE at 3 months was 1.34% (95% CI: 1.04– 1.64). There were 16 PE (rate 0.25%) and 3 were fatal. The rate of major bleeding was 1.2%. At 6 months, 1006 patients (14.7%) were dead. Significant risk factors for symptomatic VTE were: history of VTE (OR 2.9), induction of anesthesia until arrival in the recovery room > 2 hrs (OR 2.5), and varicose veins/post-thrombotic syndrome (OR 2.2). LMWH prophylaxis significantly reduced the risk of symptomatic VTE (OR 0.2). Significant predictive factors for mortality were: cancer (OR 2.3), surgical complications requiring re-intervention (OR 1.8), confusion before fracture (OR 1.8), ASA score ≥3 (OR 1.7), BMI ≤18 kg/m2 (OR 1.6), congestive heart failure (OR 1.6), atrial fibrillation (OR 1.6) and age > 80 years (OR 1.1). Conclusions Extended LMWH prophylaxis is applied widely after hip fracture surgery in France. The current rate of postoperative VTE is low. However, a major change in the care of these patients is needed because of the high mortality rate

Although wait-times for hip fracture surgery have been linked to mortality and are being used as quality-of-care indicators worldwide, controversy exists about the duration of the wait that leads to complications. Our objective was to use new population-based wait-time data to emprically derive an optimal time window in which to conduct hip fracture surgery before the risk of complications increases. We used health administrative data from Ontario, Canada to identify hip fracture patients between 2009 and 2014. The main exposure was the time from hospital arrival to surgery (in hours). The primary outcome was mortality within 30 days. Secondary outcomes included a composite of mortality or other medical complications (MI, DVT, PE, and pneumonia) also within 30 days. Risk-adjusted cubic splines modeled the probability of each complication according to wait-time. The inflection point (in hours) when complications began to increase was used to define ‘early’ and ‘delayed’ surgery. To evaluate the robustness of this definition, outcomes amongst propensity-score matched early and delayed patients were compared using percent absolute risk differences (% ARDs, with 95% confidence intervals [CIs]). There were 42,230 patients who met entry criteria. Their mean age was 80.1 (±10.7) and the majority were female (70.5%). The risk of complications modeled by cubic splines consistently increased when wait-times were greater than 24 hours, irrespective of the complication considered. Compared to 13,731 propensity-score matched patients who received surgery earlier, 13,731 patients receiving surgery after 24 hours had a significantly higher risk of 30-day mortality (N=898 versus N=790, % ARD 0.79 [95% CI 0.23 to 1.35], p = .006) and the composite outcome (N=1,680 versus N=1,383, % ARD 2.16 [95% CI 1.43 to 2.89], p < .001). Overall, there were 14,174 patients (33.6%) who received surgery within 24 hours and 28,056 patients (66.4%) who received surgery after 24 hours. Increased wait-time was associated with a greater risk for 30-day mortality and other complications. The finding that a wait-time of 24 hours represents a threshold defining higher risk may inform existing hip fracture guidelines. Since two-thirds of patients did not receive surgery within this timeframe, performance improvement efforts that reduce wait-times are warranted

Introduction. Delay, postponing and cancellation of hip fracture surgery leads to unnecessary starvation and adverse effects on patients and resources. Best Practice Tariffs (BPT) have been introduced to incentivise organisation into optimising the overall care for this type of injuries. Methods. Retrospective observational analysis of all consecutive cases of hip fractures over a period of 18 months; this period spanned the introduction of BPT: 10 months before and 8 months after. Data on delay, postponing and cancellation of surgery were recorded and analysed. Results. Total of 584 cases with a surgery cancellation rate of 21% (n=121). Top three reasons for cancellation: 48% medically unfit, 32 % lack of operating time, 6% patient unprepared. Rate of surgery cancellation pre-BPT 26% (n=85), post-BPT 14% (n=36). Top three reasons for cancellation pre vs. post BPT were respectively: medically unfit 48% vs. 47%, lack of operating time 32% vs. 33%, patient unprepared 6% vs. 8%. Mean time from admission to surgery was in pre-BPT: 43.03 hours, in post-BPT: 34.33 hours. Surgery occurred at ≥36 hours after admission in 43.3% (first group), in 25% (second group). Lack of operating theatre time as reason for delay in surgery dropped from 37% to 20%. In contrast, the rate of theatre list overrun increased from 7% to 16%. Conclusions. According to our district general hospital experience; the implementation of national guidelines and financial incentives helped reduce time delay and rate of cancellation of hip fracture surgery. These changes were achieved despite access to the same level of resources

The aim of this study was to investigate the risk factors, financial costs and outcomes associated with infection after hip fracture surgery. Prospective hip fracture data from the University Hospital, Nottingham, was analysed, assessing patients with either deep or superficial wound infections admitted over a five year period. 3605 patients underwent hip fracture surgery. 2.3% of these patients developed a wound infection of which 1.2% were deep wound infections. 75% of infections were due to Staphylococcus aureus and 50% of all infections were caused by methicillin-resistant Staphylococcus aureus. No statistically significant risk factors for the development of infection were identified in this study. Length of stay, cost of treatment and pre-discharge mortality were all increased with deep infection. Deep wound infection increased the average length of stay from 28 days to 100 days. This quadrupled the ward costs. The mean overall hospital cost of treating a hip fracture complicated by deep wound infection was £34903 compared to £8979 fro those who did not develop infection. Pre-discharge mortality increased from 24.2% in the control group to 30% in the infected group (p<0.006). MRSA significantly increased costs, LOS, and pre-discharge mortality compared with non-MRSA infection. These results show the huge impact that infection after hip fracture surgery has both on mortality and hospital costs

There is little evidence from the literature regarding the timing of hip fracture surgery for patients who are on the antiplatelet agent clopidogrel bisulphate (Plavix) (1). We report the results of a retrospective case control study of 40 patients comparing the timing of surgery for patients taking clopidogrel against a control group of those not taking an antiplatelet agent. Time to surgery, length of stay, transfusion requirements, wound problems and other post operative complications were examined. Within the study group of patients taking clopidogrel, we also compared those who underwent surgery within four days of stopping the clopidogrel and after four days. The transfusion requirements were greater in those patients on clopidogrel prior to admission. Wound healing and post operative complications were similar between the two groups. Total length of hospital stay and post operative length of stay were longer in the clopidogrel group. There was an increase in transfusion requirements and post operative length of stay in patients on clopidogrel undergoing early surgery (within 4 days) compared to the group where surgery was delayed. We conclude that, in this small study, transfusion requirements and length of stay were greater in patients on clopidogrel. Transfusion requirements and post operative length of stay were also greater if surgery was performed within four days of omitting clopidogrel. Further studies are required to determine optimal timing of surgery following discontinuation of clopidogrel

Hip fracture is associated with highest mortality following trauma in the elderly. The objective of this study is to evaluate the association between duration of anaesthesia and duration of surgery with 30 days mortality following hip fracture surgery. This retrospective cohort study reviewed patients underwent surgery following hip fracture in a district general hospital. Patients less than 65 years, periprosthetic and pathological fractures were excluded. Totally 254 patients were included in the study, who had surgery between February 2005 and September 2008 (20 months period). Mortality details retrieved through National Statistics database. Chi Square tests and Logistic regression analyses were performed to check the relationship between 30 days mortality and all independent variables including duration of anaesthesia and duration of surgery. The incidence of 30 days mortality following hip fracture surgery was 9.4%. The commonest reason of death was cardiac failure and chest infection. Patients who had General anesthesia (GA) had more complications and mortality in comparison with those who had regional anaesthesia. GA increases the odds of 30 days mortality to 2.5 times. Patients under American Society of Anesthesiologists (ASA) II had decreased odds of 30 days mortality than ASA III & IV (odds Ratio 0.16). However duration of anesthesia up to 120 minutes and duration of surgery up to 90 minutes were not associated with 30 days mortality (P>0.05). The 30 days mortality following dynamic hip screw fixation surgery was 14.6% and intra medullary nail was 12.5%. The 30 days mortality in cemented hemi-arthroplasty was 6.9% and uncemented hemi-arthroplasty was 6%. The 30 days mortality was nil in the group of patients who had undergone cannulated hip screw fixation. In elderly people following hip fracture surgery 30 days mortality was not affected by duration of anaesthesia and duration of surgery. However 30 days mortality was related with GA, ASA III & IV and post-operative complications mainly cardiac failure and chest infection. These patients need specialist medical care
