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

Solid organ transplant (SOT) recipients present an increased medical risk; however, few studies analyze the outcomes of these patients undergoing hip fracture surgery. This study aimes to determine the incidence of hip fracture in SOT patients and to compare the outcomes of SOT patients with matched non-SOT controls after hip fracture fixation. A retrospective review identified 20 SOT patients with hip fracture at a single center from 2016 to 2021 and were matched (1:1) with a cohort of 20 patients with hip fracture without SOT. Patient outcomes, mortality/survival and clinical outcomes were compared between two groups. The incidence of hip fracture in SOT patients was 20/1787, 1.1%. There were significant differences in mortality rate (73.3% SOT group vs. 26.7% non-SOT group; p<0.05). There were no differences in survival time (p=0.746). There were no differences in time to surgery (5.0 days SOT group vs. 3.1 days non-SOT group; p=0.109), however, there were significant differences in the hospital length of stay (14 days SOT group vs. 8.6 days non-SOT group; p=0.018). There were no differences regarding the complication rate between the two groups (9/20, 45% vs. 6/20, 30% in the SOT and non-SOT groups, respectively). SOT patients with associated hip fracture required longer hospital length of stay than non-SOT patients. SOT patients did not show greater clinical complications; however, they presented higher mortality rate compared to non-SOT patients

The HIPGEN study funded under EU Horizon 2020 (Grant 7792939) has the aim to investigate the potential of the first regenerative cell therapy for the improvement of recovery after muscle injury in hip fracture patients. For this aim we intramuscularly injected placental derived mesenchymal stromal cells during hip fracture arthroplasty. Despite not having reached the primary endpoint, which was the Short Physical Performance Battery, we could observe an increase in abductor muscle strength and a faster return to balance looking at symmetry in insole measurements during follow up

Hip fractures are a common injury in elderly patients. The UK has a National Hip Fracture Database to collect data on all patients presenting to hospital with a hip fracture. Literature evidence suggests that early surgery for hip fracture patients improves morbidity and mortality. UK national guidelines (BOA, NICE) recommend that surgery is performed within 36 hours of presentation and/or diagnosis for inpatients. Best Practice Tariffs ensure that hospitals are paid a set value if they meet this target of surgery within 36 hours. This study aims to look at reasons for delay to surgery for patients presenting to our busy level 2 trauma unit. This is a retrospective review of prospectively collected data for patients referred to the orthopaedic team at our hospital with a diagnosis of a neck of femur fracture between 1st April and 31st December 2018. Patients under the age of 65 year of age were excluded from our study. Only patients who were operated on after 36 hours were included. The database for reasons of surgical delay was reviewed and electronic patient records were used to collect further data on length of stay and 30-day mortality. A total of 249 patients were diagnosed with a hip fracture during the study period. 2 patients were too unwell for an operation and died within 24 hours of diagnosis/admission. 46 patients were included in the study. The primary reasons for surgical delay were patients not being fit for surgery (14/46) and the use of anti-coagulation (14/46). Other reasons included a lack of surgical capacity (7/46) and delayed diagnosis due to further imaging (CT). Mean delay to surgery was 51.8 hours (range 34.5 – 157.2 hours; median 42.9 hours), mean length of stay 20.4 days (range 5.3 – 55.7 days, median 15.6 days). 30-day mortality was 4/46 (8.6%) for patients who were delayed. Many of the issues we found in this study are unusual however these problems are commonly faced in many level 2 trauma units that serve an ever growing ageing population. Changing practice to provide improved out-of-hours medical care to facilitate medical optimisation and using current literature evidence that shows that the use of DOACs/NOACs does not adversely affect outcomes when patients are operated on within 24 hours of the last dose may help improve times to surgery

To conduct a meta-analysis for intertrochanteric hip fractures comparing in terms of efficacy and safety short versus long intralomedullary nails. A pubmed search of the last 10 years for intertrochanteric fracture 31A1-31A3 according to the AO/OTA classification was performed. Baseline characteristics of each article were obtained, complication measures were analyzed: Peri-implant fracture, reoperations, deep/superficial infection, and mortality. Clinical variables consisted of blood loss (mL), length of stay (days), time of surgery (min) and nº of transfusions. Functional outcomes were also recorded. A meta-analysis was performed with Review Manager 5.4. Twelve studies were included, nine were retrospective. The reoperations rate was lower in the short nail group and the peri-implant fracture rate was lower in the long nail group (OR 0.58, 95% CI 0.38 to 0.88) (OR 1.88, 95% CI 1.04 to 3.43). Surgery time and blood loss was significantly higher in the long nail group (MD −12.44, 95% CI −14.60 to −10.28) (MD −19.36, 95% CI −27.24 to −11.48). There were no differences in functional outcomes. The short intramedullary nail has a higher risk of peri-implant fracture; however, the reoperation rate is lower compared to the long nail. Blood loss and surgery time was higher in the long nail group

The National Hip Fracture Database (NHFD) is a clinically led web based audit used to inform national policy guidelines. The aim of this audit was to establish the accuracy of completion of NHFD v13.0 theatre collection sheets, identify common pitfalls and areas of good practice, whilst raising awareness of the importance of accuracy of this data and the manner in which it reflects performance of CAH Trauma & Orthopaedic unit in relation to national guidelines. Our aim was to improve completion up to >80% by the operating surgeon and improve overall accuracy. The methodology within both cycles of the audit were identical. It involved reviewing the NHFD V13.0 completed by the operating surgeon and cross-checking their accuracy against clinical notes, operation notes, imaging, anaesthetic charts and A&E admission assessment. Following completion of cycle 1 these results were presented, and education surrounding V13.0 was provided, at the monthly trust audit meeting. At this point we introduced a sticker onto the pre-operative checklist for Hip fractures. This included time of admission and reason for delay. We then completed a re-audit. Cycle-1 included 25 operations, 56% (n=14) had a completed V13.0 form. Of these 21% (n=3) were deemed to be 100% accurate. Cycle-2 included 31 operations (between April – June 21) 81% (n=25) had a completed intra-operative from and showed an increase in accuracy to 56% (n=14). Through raising awareness, education and our interventions we have seen a significant improvement in the completion and accuracy of v13.0. Although 100% accuracy was not achieved its clear that education and intervention will improve compliance over time. Through the interventions that we have implemented we have shown that it is possible to improve completion and accuracy of the NHFD V13.0 theatre collection sheet locally and feel this could be implemented nationally

Abstract. Objectives. Our study evaluates financial impact to the Best Practice Tariff (BPT) of hip fracture patients on Novel Oral Anti-Coagulant (NOAC) medication. Since their approval by NICE for the prevention of stroke and systemic embolism in non-valvular atrial fibrillation, the incidence of hip fracture patients admitted to hospitals on NOAC medication (e.g. rivaroxiban, apixaban) has been increasing. BPT for hip fractures has two components: a base tariff and a conditional top-up tariff of £1,335 per patient (applied to patients of 60 years of age). For the top-up tariff, six criteria must be met, of which time-to-surgery within 36 hours is one. Our department currently recommends withholding NOAC medication and delaying surgery for at least 48 hours as per our Trust's haematology guidelines to reduce intra-operative bleeding risk. Therefore, the conditional top-up tariff cannot be claimed for these patients. Method. A retrospective review of our Trust hip fracture patients over 60 years of age admitted during 2019 on NOAC medication using National Hip Fracture Database (NHFD). Results. 545 hip fracture patients had operative treatment at our Trust during the one-year period of 2019. 31 of these patients were admitted on NOAC medication, and therefore had to stop the NOAC and wait for at least 48 hours before having surgery. This translates to a potential hip fracture BPT loss of £41,385 in 2019, as the conditional top-up tariff could not be claimed. Conclusion. This study illustrates the large financial impact to BPT that hip fracture patients admitted on NOAC medications has at our Trust. It raises the argument as to whether the BPT should allow for an increased length of time until surgery for such patients, to allow safe surgical treatment with reduced bleeding risk.

Background. Lack of ability in basic mobility skills is associated with increased mortality in patients with hip fractures. The aim of this study was to identify predictors for performing basic mobility skills at discharge. Methods. From June 2015 to May 2016, 235 consecutive patients (76% female, median age 85 (78–89 IQR)) with hip fractures admitted to the Department of Orthopedic Surgery at North Denmark Regional Hospital were included. Basic mobility was assessed at discharge using the Cumulated Ambulation Score (CAS), which consists of 1) getting in and out of bed, 2) rising from a chair and 3) walking. Possible scores for each task is: unable (CAS=0), supported (CAS=1) or independent (CAS=2). A total score of 6 indicates independence in basic mobility. Inclusion was restricted to first time hip fractures and age ≥65. Exclusion criteria were death during admission or unrecorded CAS at discharge. Results. Before surgery 90.6% were independent in basic mobility (CAS=6). Getting out of bed at discharge: independently 37.5%, supported 56.5% and unable 6.0%. Rising from a chair: independently 49.8%, supported 43% and unable 7.2%. Walking: independently 43.8%, supported 38.3% and unable 17.9%. A total of 79 (33.6%) patients achieved independence in all tasks (CAS=6) at discharge. Independence in: 1) getting in and out of bed, 2) rising from a chair, and 3) walking, respectively had significant association with advanced age, length of stay and Charlson Comorbidity Index >0. Medial fractures were associated with inability to rise from a chair. Advanced age was the only variable significantly associated with each task of CAS. Pre-fracture function was associated with the inability to rise from a chair and walking. Delay of surgery > 48 hours after admission was significantly associated with the inability to walk. Conclusion. Elderly patients with comorbidities and dependent pre-fracture function should receive extra attention in rehabilitation

This study aims to investigate that a single dose of tranexamic acid (TXA) will reduce blood loss and transfusion rates in elderly patients, undergoing intertrochanteric (IT) or femoral neck fractures surgery. Consecutive elderly patients receiving hip fracture surgery for stable or unstable IT fracture, treated with short intramedullary nail (IMN) insertion as well as cemented hemiarthroplasty for acute femoral neck (subcapital) hip fracture, were screened for inclusion in this single-centre randomized trial. Patients were randomly allocated to a study group by sealed envelope. One TXA dose of 15 mg/kg i.v. diluted in 100 ml N/S or one placebo dose i.v. in 100 ml N/S were administered 5 mins before the skin cut. Haemoglobin (Hb) concentration was measured at admission time and prior to surgery. Post-operatively it was measured on a daily basis until day 4, giving a total of four Hb measurements (days 1 to 4). The transfusion trigger point was determined in accordance with the French guidelines for erythrocyte blood transfusion. The transfusion trigger was 10 g/dl for patients at risk, while in all other cases, it was 9 g/dl. Information regarding the transfusions number was assessed directly by the hospital blood bank database. Blood loss was calculated by the Hb dilution method. Nadler's formula was used to calculate patients' blood volume. For calculation of total blood loss (TBL) expressed to total Hb loss and total Volume loss, the number of transfusions (55 grams of Hb per transfusion), the Hb concentration on preoperatively (Hgbi) and the Hb concentration on the last measure (Hgbe) were used. (Hb balance method). The primary efficacy outcome was the number of transfusions of allogeneic RBC from surgery up to day 4. The secondary ones were the total blood loss from surgery to day 4 as it was calculated by Hb-balance method. After randomization, 35 patients with femoral neck fracture and 30 patients with IT fracture received TXA prior to surgery. Respectively, 30 patients with femoral neck fracture and 55 with IT fracture didn't receive TXA. The groups did not differ significantly in their basic demographics (age, gender, BMI, injury mechanism, ASA score, co-morbidities). Results showed that patients undergoing hemiarthroplasty after receiving TXA, were transfused with less allogeneic RBC and had less total blood loss than patients that didn't receive TXA, but without statistical significance. While patients treated with IMN in the TXA group received a significantly lower number of RBC units than the control group (1.28 ± 1.049 vs 2.075 ± 1.685), (P = 0.0396), had a significantly lower loss of Hb (98.59 ± 55.24 vs 161.6 ± 141.7), (P = 0.0195) and a lower total blood volume loss (951.3 ± 598.9 ml vs 1513 ± 1247 ml), (P = 0.023). This trial confirmed TXA administration efficacy in reducing blood loss and transfusion rate in elderly patients undergoing hip fracture surgery. A TXA single dose may be a safer option, taking into account these patients' physiological status and co-morbidities

Background. The Nottingham Hip Fracture Score (NHFS) is a risk stratifying score that estimates the 30-day and 12-month mortality rates of hip fracture patients. To date, it has only been validated in few centres in the UK. Our study aims to see how our mortality rates compare with those predicted by the NHFS. Methods. The Nottingham Hip Fracture Database was reviewed for patients presenting to our unit from August 2012 - March 2013 with a neck of femur fracture. Patient information was obtained from the database and our online electronic patient records for NHFS calculation. Patients with incomplete data were excluded. Results. 285 patients were identified, 11 were excluded. 69 (24%) were male. The average age was 82 years. The highest mortality was in those with a NHFS=9 (50%). The high-risk (NHFS≥5) patients had a higher mortality rate (n=19, 13%) compared to the low risk group (NHFS≤4) (n=7; 5%). Conclusions. Our study shows that most of our patients had a NHFS 4 – 6, which is comparable to other units. Mortality rates increased steeply from 5% to 16% from NHFS 5–6. A validation study of the NHFS showed that a score of greater than 6 was more closely correlated with high mortality. For NHFS=2, the mortality was 20%. The patient who died was a 48-year old female with breast cancer and 2 previous pulmonary emboli. The published co-morbidities for NHFS doesn't include PEs and may underestimate a patient's morbidity. Large-scale nationwide studies to determine the validity of the NHFS are needed.

Intracapsular neck of femur fractures may be treated with fixation or arthroplasty, depending on fracture characteristics and patient factors. Two common methods of fixation are the sliding hip screw, with or without a de-rotation screw, and cannulated screws. Each has its merits, and to date there is controversy around which method is superior, with either method thought to risk avascular necrosis of the femoral head (AVN) rates in the region of 10–20%. Fixation with cannulated screws may be performed in various ways, with current paucity of evidence to show an optimum technique. There are a multitude of factors which are likely to affect patient outcomes: technique, screw configuration, fracture characteristics and patient factors. We present a retrospective case series analysis of 65 patients who underwent cannulated screw fixation of a hip fracture. Electronic operative records were searched from July 2014 until July 2019 for all patients with a neck of femur fracture fixed with cannulated screws: 68 were found. Three patients were excluded on the basis of them having a pathological fracture secondary to malignancy, cases were followed up for 2 years post-operatively. Electronic patient records and X-rays were reviewed for all included patients. All X-rays were examined by each team member twice, with a time interval of two weeks to improve inter-observer reliability. 65 patients were included with 2:1 female to male ratio and average age of 72 years. 36 patients sustained displaced fractures and 29 undisplaced. Ten patients sustained a high-energy injury, none of which developed AVN. Average time to surgery was 40 hours and 57 patients mobilised on day one post-operatively. All cases used either 7 or 7.3mm partially threaded screws in the following configurations: 2 in triangle apex superior, 39 triangle apex inferior, 22 rhomboid and 2 other, with 9 cases using washers. All reductions were performed closed. Five (8%) of our patients were lost to follow-up as they moved out of area, 48 (74%) had no surgical complications, seven (11%) had mild complications, three (5%) moderate and two (3%) developed AVN. Both of these sustained displaced fractures with low mechanism of injury, were female, ASA 2 and both ex-smokers. One received three screws in apex inferior configuration and one rhomboid, neither fixed with washers. Our AVN rate following intracapsular hip fracture fixation with cannulated screws is much lower than widely accepted. This study is under-powered to comment on factors which may contribute to the development of AVN. However, we can confidently say that our practice has led to low rates of AVN. This may be due to our method of fixation; we use three screws in an apex inferior triangle or four screws in a rhomboid, our consultant-led operations, closed reduction of all fractures, or our operative technique. We pass a short thread cannulated screw across the least comminuted aspect of the fracture first in order to achieve compression, followed by two or three more screws (depending on individual anatomy) to form a stable construct. Our series shows that fixation of intracapsular hip fractures with cannulated screws as we have outlined remains an excellent option. Patients retain their native hip, have a low rate of AVN, and avoid the risks of open reduction

Background. Since it's establishment in 2007, the National Hip Fracture Database [NHFD] has been the key driving force in improving care for hip fracture patients across the UK. It has facilitated the setting of standards to which all musculoskeletal units are held, and guides service development to optimise outcomes in this group of patients. As with any audit, the ability to draw conclusions and make recommendations for changes in practise relies on the accuracy of data collection. This project aimed to scrutinise the data submitted to the NHFD from a Major Trauma Centre [MTC], focusing on procedure coding, and discuss the implications of any inaccuracies. Method. The authors performed a retrospective analysis of all procedure coding data entered into the NHFD from July 2009 to July 2014 at Cambridge University Hospitals NHS Foundation Trust. We examined 1978 cases for discrepancies, comparing procedure codes entered into the NHFD with post-procedure imaging and operative notes. Results. The procedure coding data submitted to the NHFD was highly inaccurate, with incorrect procedure codes in 24% of the 1978 cases reviewed. In particular, coding of cemented total arthroplasty and cemented bipolar hemiarthroplasty, with coding errors in registry data of 42% and 39% respectively. Of the 67 THRs performed only 52% were correctly coded for, and only 626 of the 915 hemiarthroplasties (68%). 16% of cannulated hip screws actually underwent primary arthroplasty. Conclusions. This study highlights the inaccuracy of coding data entered into the NHFD from a Major Trauma Centre, with data on arthroplasty being particularly inadequate. The unreliability of procedure data leaves us unable to evaluate surgical treatment strategies using the NHFD. This has worrying implications for standard setting, service development and, consequently, patient care. Level of evidence. 2c

Objectives. Aged trauma patients are at high risk for various comorbidities and loss of function following hip fracture. Consequently a multidisciplinary approach for the treatment of these patients has become more famous in order to maintain the patients” activity level and health status prior to trauma. This study evaluates the effect of a multidisciplinary inpatient rehabilitation on the short- and long-term functional status of geriatric patients following hip fracture surgery. Methods. A collective of 158 hip fracture patients (> 80 years) who underwent surgery were included in this study. An initial Barthel Index lower than 30 points was a criteria to exclude patients from this study. Two subgroups, depending on the availability of treatment spots at the rehabilitation center were made. No other item was used to discriminated between the groups. Group A (n=95) stayed an average of 21 days at an inpatient rehabilitation center specialized in geriatric patients. Group B (n=63) underwent the standard postoperative treatment. As main outcome parameter we used the Barthel Index, which was evaluated for every patient on the day of discharge and checkups after three, six and twelve months. Results. After three months, the average Barthel Index was 82,27 points for group A and 74,68 points for group B (p=0,015). In the six-months-checkup group A”s average Barthel Index was 84,05 points and group B”s was 74,76 points (p=0,004). After twelve months, patients from group A had an average Barthel Index of 81,05 while patients from group B had an average Barthel Index of 71,51 (p=0,010). Conclusion. This study reveals a significant better outcome in both, the short-term and the long-term functional status for geriatric hip-fracture patients, who underwent an inpatient treatment in a rehabilitation center following the initial surgical therapy. This is shown at the timepoints three, six and twelve month after discharge. To maintain quality of life and mobility as well as the patient”s independence in daily life, a treatment in a rehabilitation center specialized in geriatric patients is highly recommendable

The surgical treatment options for patients who have sustained an intra-capsular hip fracture can vary depending on a number of patient and fracture related factors. Currently most national guidelines support the use of cemented prostheses for patient undergoing hemiarthroplasty surgery. Uncemented prostheses are commonly used for a variety of indications including those patients who have significant medical co-morbidities. To determine whether cemented hemiarthroplasty is associated with a higher post operative mortality when compared to uncemented procedures. Data were extracted from the Scottish SMR01 database from 01/04/1997 from all patients who were admitted to hospital after sustaining a hip fracture. We investigated mortality at day 1,2,4,7,30, 120 and 1 year from surgery vs. that on day 0. In order to control for the effects of confounding variables between patients cohorts, 12 case-mix variable were used to construct a multivariable logistic regression analysis model to determine the independent effect of prosthesis design. There were 52283 patients included in the study. Mortality for osteosynthesis of extra-capsular fractures was consistently lower when compared to that for surgical procedures for intra-capsular fractures. At day 0, uncemented hemiarthroplasty had a lower associated mortality (p<0.001) when compared to cemented implant designs. However, this increased mortality was equal to 1 extra death per 2000 procedures. From day 1 onward mortality for cemented procedures was equal to or lower than that of uncemented. By day 4, cumulative mortality was less for cemented than for uncemented procedures. Complication and re-operation rate was significantly higher in the uncemented cohort. The use of uncemented hemiarthroplasty for the treatment of intra-capsular hip fractures cannot be justified in terms of early/late post-operative mortality

Fragility fractures are an increasing cause of morbidity and mortality in the elderly population. Their association with reduced bone mineral density (BMD) is well documented. It is a reasonable assumption that hip fracture severity is linked to the magnitude of bone loss, (the lower the BMD, the more severe the fracture), however it is not known whether this correlation exists. Our aim therefore was to investigate the relationship between BMD and hip fracture severity. We reviewed 142 patients, 96 females and 46 males, mean age 74 years (49-92), who had sustained a hip fracture following a simple ground level fall. All had subsequently undergone DEXA bone scanning of the contralateral hip and lumbar spine. Fractures were classified as intra-capsular, extra-capsular or subtrochanteric, then sub-classified using the Garden, Jensen and Seinsheimer classifications respectively. They were grouped into simple (stable) or comminuted (unstable) fracture patterns. Risk factors for osteoporosis were recorded. A low hip BMD (<2.5) was associated with an increased risk of extra-capsular fracture (p=0.025). However, no association with fracture type (extra vs. intra-capsular, p>0.05) was identified with the following variables; age, gender, BMI <25, smoking, and excess alcohol intake. We did not find any statistically significant associations between fracture severity and the nine principle variables tested for: age; gender; smoking; BMI < 25; alcohol excess and low hip or lumbar BMD T or Z score <-2.5. Although the association between BMD and risk of fragility fractures is well documented, the results of this study would suggest that severity of hip fractures does not follow this correlation. Therefore, no assumption can be made about BMD of the proximal femur based on the severity of fracture observed on plain radiographs alone

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

Hyponatraemia is one of the most common electrolyte disorders in the elderly and has considerable associated morbidity and mortality. In this study we report the prevalence and independent risk factors for the development of post-operative hyponatraemia after surgery for hip fracture. We conducted a retrospective cohort study of 144 consecutive patients who underwent surgery after sustaining a hip fracture. Patient medical case-notes, operative notes and online biochemistry results were used to obtain relevant data which was entered into a database. Pre-operative (30/144, 21%) and post-operative hyponatraemia (49/144, 34%) was common. However, most cases were mild (plasma sodium >130 mmol/l) and only 1% of pre-operative and 6% of post-operative patients had moderate/severe hyponatraemia (plasma sodium <130mmol/l). One of 3 post-operative deaths involved a patient with moderate hyponatraemia as a consequence of severe congestive cardiac failure. In order to determine the independent relationship between several reported risk factors and hyponatraemia we constructed a multivariable logistic regression model. Female gender, pre-operative hyponatraemia and hypotonic fluid administration were all significantly associated with the development of post-operative hyponatraemia. Age and thiazide diuretics both had positive risk associations however were not statistically significant. Hyponatraemia is a common problem in hip fracture patients. While the majority of cases in this series were mild, 6% of patients suffered from moderate/severe hyponatraemia post-operatively. Female gender, pre-operative hyponatraemia and hypotonic fluid administration are all important and independent risk factors for the development of hyponatraemia. Hypotonic intravenous fluids should be avoided unless clinically indicated in this patient group

Collection of new data for the Scottish hip fracture audit stopped in December 2008. The proposed standard of operating on 98% of all hip fractures within 24 hours of admission, subject to medical fitness and during safe operating hours should now be maintained. Methods. We prospectively collected data from 102 consecutive hip fracture patients documenting the patient's journey from admission to discharge from the orthopaedic ward to look at whether the standard had been maintained. Results. 50% of patients get to theatre 24hrs or earlier with 60% catheterised perioperatively.50% of patients were moved from the acute orthopaedic facility at a week with less than 20% of these getting back to their usual place of residence. 25% were still on the acute ward at two weeks and 3% died in the immediate post operative period. However, the number of co-morbidities did not seem to correlate with time to discharge. The majority of patients transferred to onward care moved to the geriatric rehabilitation ward within the hospital. Prioritisation of hip fracture patients on the trauma list needs to be continued along with improvements in the availability of rehabilitation beds. Pre-operative medical work up for patients with reversible illness and post-operative geriatric care will improve the outcomes for these frail patients

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 surgical treatment options for patients who have sustained an intra-capsular hip fracture can vary depending on a number of patient and fracture related factors. Currently most national guidelines support the use of cemented prostheses for patient undergoing hemi-arthroplasty surgery. Uncemented prostheses are commonly used for a variety of indications including those patients who have significant medical co-morbidities. To determine whether cemented hemi-arthroplasty is associated with a higher post operative mortality when compared to uncemented procedures. Data was extracted from the Scottish SMR01 database from 01/04/1997 from all patients who were admitted to hospital after sustaining a hip fracture. We investigated mortality at day 1, 2, 4, 7, 30, 120 and 1 year from surgery vs. that on day 0. In order to control for the effects of confounding variables between patients cohorts, 12 case-mix variable were used to construct a multivariable logistic regression analysis model to determine the independent effect of prosthesis fixation method. There were 64,979 patients were included in the study. Mortality for osteosynthesis of extra-capsular fractures was consistently lower when compared to that for surgical procedures for intra-capsular fractures. At day 0, uncemented hemi-arthroplasty operations had a lower associated mortality (p<0.001) when compared to cemented implant designs. Unadjusted figures showed an increased mortality equal to 1 extra death per 424 procedures. By day 1 this had become 1 extra death per 338 procedures. By day 7 cumulative mortality was less for cemented than for uncemented procedures though this did not reach significance until day 120. When compared to uncemented fixation techniques, cemented hemiarthroplasty is associated with a higher mortality in the immediate postoperative period. However, by day 120 and beyond the trend is reversed
