In Scotland, the number of primary total knee replacements performed annually has been increasing steadily. The price of the implant is fixed but the length of hospital stay is variable. We prospectively investigated all patients who underwent primary unilateral total knee replacement in the Scottish region of Fife, between December 1994 and February 2007 and assessed their recorded pre-operative details. The data were analysed using univariate and multiple linear regression statistical analysis. Data on the length of stay were available from a total of 2106 unilateral total knee replacements. The median length of hospital stay was eight days. The significant pre-operative risk factors for an increased length of stay were the year of admission, details of the consultant looking after the patient, the stair score, the walking-aid score and age. Awareness of the pre-operative factors which increase the length of hospital stay may provide the opportunity to influence them favourably and to reduce the time in hospital and the associated costs of unilateral total knee replacement

Introduction: In Scotland, the number of primary total knee replacements has been steadily increasing since 1992. It has been predicted that the number of total knee replacements performed annually will soon outstrip the number of hip replacements. The price of the implant is fixed but the length of hospital stay, and associated cost, is variable. An understanding of what currently influences length of hospital stay may be of paramount importance in order that we can influence some of these parameters, with resulting benefit to our patients as well as contributing significantly and favourably towards the health economics of this procedure. Materials and Methods: All patients who underwent primary unilateral total knee replacement in the region of Fife, Scotland, UK, during the period December 1994 to February 2007 were prospectively investigated. The following information was gathered: age, sex, body mass index (BMI), year of operation, day of operation, diagnosis, surgeon grade, consultant performing the operation, walking score, walking aids score, stair score, American Knee Society score (pain, stability and range of motion), length of operation, need for lateral release, patella replacement, urinary catheterisation, blood transfusion, presence of deep or superficial infection, pre and post-operative haemoglobin values, haemoglobin drop, and length of hospital stay. All the data was analysed using univariate and multiple linear regression statistical analysis. Results: Data on length of hospital stay was available from a total of 2105 unilateral total knee replacements. Length of stay varied from 4 to 70 days, with a mean of 9.4 and a median of 8.0. There were numerous highly significant predictors of increased length of hospital stay, when considered separately. Many of these independently significant factors remained significant when adjusted for the effects of the others. These included age of the patient, year of admission, consultant performing the operation, use of a walking aid, lateral release, deep and superficial infection, pre and post-operative haemoglobin values, urinary catheterisation and blood transfusion. Of note, the day of operation and high BMI did not influence the length of stay. Conclusion: Prolonged hospital stay following total knee replacement is associated with demographic, preoperative, intra-operative and post-operative factors. An awareness of these factors gives us the opportunity to make attempts to influence them favourably with resulting reduction in length of hospital stay and, therefore, the associated costs

Introduction and Objective. Several factors contribute to the duration of the hospital stay in patients that undergo to total hip arthroplasty (THA), either subjective or perioperative. However, no definite evidence has been provided on the role of any of these factors on the hospitalization length. The aim of this retrospective investigation is to evaluate the correlation between several preoperative and perioperative factors and the length of hospital stay (LOS) in patients that underwent elective total hip arthroplasty. Materials and Methods. Medical records of patients that underwent THA since the beginning of 2016 to the end of 2018 were retrospectively screened. Demographics, comorbidities, renal function, whole blood count. and length of post-operative ward stay were retrieved. The association between clinical, biochemical and surgical factors and the length of hospital stay was explored by means of linear regression models. Results. A total of 743 subjects were included. Retrieved comorbidity included arterial hypertension (47%), dyslipidaemia (20%), chronic kidney disease (CKD) (12%) and diabetes mellitus (9%). The median length of post-operative hospital stay was 4 days (IQR: 2). Variables associated with linear increase of hospitalization length were the estimated Glomerular Filtration Rate (eGFR) (Beta −0.01, 95% CI −0.02, 0), CKD (Beta 0.82, 95% CI 0.29, 1.34), duration of surgery (Beta 0.69, 95% CI 0.44, 0.94). After correction for multiple confounders, the CKD (a-Beta 1.58 95%CI 0.00 – 3.22) and operation time (a-Beta 0.67, 95% CI 0.42, 0.92) were consistently associated with the outcome. Conclusions. Our analysis demonstrated a significant role played by the eGFR (as an index of renal function) in influencing the length of hospital stay

Background. Patients who undergo elective hip and knee arthroplasty often have multiple risk factors increasing their likelihood of suffering from hyponatraemia post operatively. Consequently suffering from hyponatraemia post elective hip and knee arthroplasty is common. Consequently we wanted to assess the occurrence of hyponatraemia in our elective arthroplasty unit, assess our effectiveness in managing this and importantly assess how its occurrence impacted on length of patient stay. Method. Retrospective analysis of elective hip and knee arthroplasty patients over a five month period. Pre-operative and post-operative sodium levels analysed and their grade measured using NICE reference ranges. In post-operative hyponatraemic patients blood results were analysed up until discharge. Discharge summaries were reviewed to assess communication between primary and secondary care. Length of admission calculated. Formal action plan developed in partnership with the anaesthetic department to improve future management. Results. 103 patients assessed. 24 (23%) suffered from post-operative hyponatraemia. 11 (48%) were discharged with a normalised sodium. 7 (29%) had documentation regarding their hyponatraemia in the discharge summary. 101 (98%) had a sodium drop post-operatively and 2 patients were hyponatraemic pre-operatively. Average length of stay for hyponatraemic hip patients was 5.00 days compared to 4.20 days for patients with normal sodium levels. Hyponatraemic post op knee patients had an average in hospital stay of 5.09 days compared to 4.13 days in knee patients with a normal post-operative sodium level. Conclusion. Hyponatraemia is common in the post-operative arthroplasty patient. In our unit it led to an increase in length of hospital stay. We believe the introduction of a structured post-operative oral rehydration regime with isotonic fluid would be a simple method to reduce occurrence post operatively. We feel standardising intra-operative fluid prescribing will reduce the likelihood of pushing patients into a post-operative hyponatraemic state. Finally we have introduced a hyponatraemia management flowchart to the department so ward based doctors can recognise and effectively manage hyponatraemic patients. If these measures are implemented length of stay in hospital can potentially be reduced

Introduction. Length of hospital stay in Japan is 20 to 30 days, which is much longer than United States. Reasons of such differences are utilization of a national insurance system in Japan, and more than 90 % of patients are discharged to home. The purpose of the current study was to investigate inpatient recovery process during relaxed standing, and to clarify the appropriate length of hospital stay following TKA. Methods. Thirty patients (25 Females and 5 Males) with knee osteoarthritis, 67 to 84 years old (mean 75), participated. All the subjects provided informed consent and the study was approved by our institution. The subjects were asked to step on the two scales and perform relaxed standing, placing each foot on each scale independently. Evaluations were divided into two categories; subjective and objective components. Subjective component was based on pain level, and objective component consisted of vertical knee force and knee flexion angle during relaxed standing. Namely, subjective pain level on TKA side, vertical knee forces (%BW) on TKA side, and knee flexion angles (degrees) on TKA side during relaxed standing, were examined. Each evaluation was done twice. Data evaluations were done pre- and post-operatively. Postoperative evaluations were done daily from postoperative day 3 to 21. Pain level, vertical knee force, and knee flexion angle were evaluated using visual analog scale (100 mm), same type of two scales, and goniometer, respectively. Vertical knee force (%BW) was defined as the ratio of weight bearing on TKA side to body weight in our study. An average value of two trials was calculated. Values of preoperative measurements were used as controls. Statistical difference between the data was evaluated using two-tailed repeated-measures of analysis of variance. After a significant P value (< 0.05) was determined, a post hoc Bonferroni correction was performed to compare selected mean values, and P-values of < 0.05 was considered as significant. Results. Changes of subjective component (Fig. 1). Preoperative pain score was 69.1. After TKA, pain level became maximum on postoperative day 3. Thereafter, pain gradually decreased, and on postoperative day 8, pain score was significantly smaller than preoperative score. Changes of objective component (Fig. 2, 3). Preoperative vertical knee force was 43.5 (%BW). Similarly, after TKA, it became minimum on postoperative day 3. Thereafter, knee force gradually increased, and on postoperative day 17, knee force was significantly larger than preoperative force. Preoperative knee flexion angle was 15.6 (degrees). After TKA, knee flexion angle during standing became maximum on postoperative day 4. Thereafter, subjects could gradually extend the knee, and on postoperative day 16, it was smaller than preoperative angle. Discussion. According to the previous study, standing is a most frequent activity during weight bearing in patient's daily life after joint replacement surgery. After TKA, significant pain reduction was observed from postoperative day 8, and objective knee condition became stable from postoperative day 16 or 17. Thus, hospital stay at least for 16 to 17 day after

Background: context: Length of hospital stay (LOS) varies widely within patients with posterior spinal fusion. So far there is little evidence on its co-variates. Purpose: This study examined which co-variates influence LOS in posterior spinal fusion. Study design: Prospective consecutive documentation of hospital based interventions in the international spine registry Spine Tango. Patient sample: Between 05/2005 and 11/2006 data of 3437 patients were documented in the registry. 790 patients with degenerative spinal disease (614) or spondylolisthesis (176), who had been treated with posterior decompression and spinal fusion, were included in this study. Median age was 62.8 yrs (min 13.2 yrs, max 89.8 yrs) with a female to male ratio of 2:1. Median LOS was 11 days (IQR 8–14 d). Outcome measures: LOS was chosen as dependent outcome variable. Methods: Multiple linear regression was performed on following independent variables: age, gender, main pathology, number of spinal segments of posterior fusion, level of fusion, number of previous spinal surgeries, operation time, clinic (number of fusions, academic status), surgeon credentials, type of fusion (sole fusion, fusion + instrumentation, fusion + instrumentation + cage). Results: Clinic (p< 0.0001) was found to be a highly significant co-variate for LOS (min 7 d, max 14 d). Number of fusions per clinic (min 25, max 434) and academic status of clinic had no influence on LOS. Further significant covariates were surgeon credentials (surgeons in training: 8.5 d, specialised spine surgeons: 11 d, orthopaedic or neurosurgeons: 12 d; p=0.001), number of spinal segments of posterior fusion (1 segment: 10 d, 2–3 segments: 12 d, 4–5 segments: 12.5 d, > 5 segments: 15 d; p=0.002), and age group (< 50 yrs: 9 d, 50–59 yrs: 11 d, 60–69 yrs: 12 d, ≥70 yrs: 13 d; p=0.01). Borderline significance was found for gender (women: 12 d, men: 10 d; p=0.05). All other variables showed no influence on LOS. Conclusion: Co-variates of LOS of patients with posterior spinal fusion are clinic, independent of number of spinal surgeries per clinic and academic status of clinic, surgeon credentials, number of segments of fusion, age group, and gender. A short LOS in surgeries performed by surgeons in training is explained by a smaller number of segments of fusions in these procedures. A subgroup analysis on the co-variate clinic should be performed assessing further explanatory variables. However, this goes beyond the possibilities of documentation in a spine registry

We analysed the clinical data of 858 consecutive primary total hip and knee replacement patients to establish how age, ASA grade, body mass index and a simplified cognitive score correlate with the length of hospital stay and early complication rates. We further used statistical regression analysis to study how hospital stay and complication rates correlate with different pre-operative grading systems based on combinations of age, ASA grade, body mass index and a cognitive score. The results indicate that age and ASA grade correlate significantly with both length of hospital stay and complication rates, while body mass index correlated poorly with both. A grading system based on a combination of age and ASA grade (the AA Grade) correlated significantly with both length of hospital stay and complication rates. Adding body mass index or a cognitive score did not significantly add to the correlation. We discuss the relevance of this simple grading system and how it might contribute to pre-operative risk assessment and peri-operative planning

In Scotland, the number of primary total knee replacements (TKRs) performed annually has been steadily increasing. Data from the Scottish Arthroplasty Project has recently demonstrated that the number of knee replacements performed annually has now outstripped the number of hip replacements. The price of the implant is fixed but the length of hospital stay (LOHS) is variable. An understanding of what currently influences LOHS may therefore be of paramount importance in order that we can influence some of these parameters, with resulting benefit to our patients as well as contributing significantly and favourably towards the health economics of this procedure. This study investigates the influence of intra- and post-operative variables on LOHS. All patients who underwent primary unilateral TKR in the region of Fife, Scotland, United Kingdom, during the period December 1994 to February 2007 were prospectively investigated. The following intra and postoperative details were recorded: length of operation, need for urinary catheterisation, patella resurfacing, lateral release, blood transfusion, the presence of superficial or deep infection, day 1 post-operative haemoglobin and haemoglobin drop (haemoglobin drop between admission haemoglobin and day 1 post-operative haemoglobin). The data was analysed using univariate and multiple linear regression statistical analysis. Data on LOHS was available from a total of 2105 primary unilateral TKRs. The median LOHS was 8.0 days. The highly significant intra and post-operative factors associated with an increased LOHS were lateral release, post-operative haemoglobin, blood transfusion, urinary catheterisation, deep and superficial infection. An awareness and understanding of these factors may enable us to influence them favourably with resulting reduction in the LOHS and, therefore, the associated costs

Introduction: Potential benefits cited for minimally invasive total hip arthroplasty (THA) include reduced peri-operative blood loss, less post-operative pain, earlier mobilisation and a shortened hospital stay. Sceptics, however, are concerned about the widespread introduction of a new surgical technique in the absence of objective scientific evidence. The ever-increasing pressure on healthcare budgets by an ageing population makes developments in surgical technique that allow earlier mobilisation and reduced length of hospital stay highly desirable. The aim of this study was to investigate whether a minimally invasive technique in THA would result in a reduced length of hospital stay compared to a standard incision of 16cm. Materials and Methods: 219 patients were randomised to either a minimally invasive (less than or equal to 10cm) or standard (16cm) incision group. Patients were blinded to their incision length. Anaesthetic and post-operative analgesic protocols were standardised. A single surgeon performed all operations using an uncemented cup and a cemented stem. Post-operative physiotherapy was standardised with the physiotherapists also blinded to incision length. Patients were discharged when safely able to transfer and mobilise with a walking aid. Results: There was no statistically significant difference in mean length of stay following surgery. This was 3.65 days (SD 2.04) for the mini-incision group and 3.68 days (SD 2.45) for the standard incision group (p=0.94). 32% of patients (35/110) in the standard incision group were able to go home on day 2 compared to 27% (29/109) in the mini-incision group. Using logistic regression analysis, the patient variables most significantly associated with a probability of discharge within 3 days of surgery were patient age (Wald=33.36, p< 0.0001) and pre-operative haemoglobin (Wald=10.53, p=0.001). 192 patients (88.5%) were discharged to their own homes with the main determinant of discharge to the patients’ own home being the availability of adequate family support. Conclusion: Total hip arthroplasty performed through a single incision minimally invasive approach does not reduce the length of hospital stay compared to THA performed through a standard incision of 16cm

Introduction: Following the successful introduction of a short stay programme for total hip replacements for selected cases in our unit, the effect of utilising an “Outreach Team” for all of our primary joint arthroplasties has been assessed. This team comprises a senior orthopaedic sister and a physiotherapy assistant. Their ethos is to provide continuity of care from the ward into the community, thereby allowing early, supported hospital discharge. We compared length of stay in a case-matched series of patients before and after the introduction of the service. Patient satisfaction was assessed and cost-benefit analysis carried out. Methods: 200 patients were enrolled on the Outreach Programme following primary joint arthroplasty. Results were compared with 200 case-matched primary arthroplasties prior to the introduction of the team. Discharge was only allowed when patients, carers and staff were happy. Patient satisfaction was assessed via questionnaires. Results: Following a cost-benefit analysis, we calculate a saving of approximately £235,000 annually, with 936 bed days saved. 99% of patients satisfied with Outreach. There were no readmissions from the Outreach group. Discussion: The use of an Outreach Team can be used to significantly reduce the length of hospital stay after primary joint arthroplasty. We feel that the use of the same carers on the ward and in the community gives a seamless transition of care, allowing patients to feel secure and confident about their early discharge with high levels of satisfaction. This simple service is highly efficient and cost-effective and we recommend our model to other units

Introduction: Ankle fractures are among the commonest orthopaedic injuries. A delay in operating is often due to the swelling associated with such fractures. On the other hand, the delay in operative fixation beyond 24 h from injury is associated with a lengthening of hospital stay which costs approximately £225 per patient per day for an acute trauma bed. Objectives: The aim of this study was to analyse the relationship between the delay in surgical intervention of open reduction and internal fixation of ankle fractures from presentation due to ankle swelling, and the length of hospital stay and postoperative complications. Patients and Methods: A retrospective study of 145 consecutive patients treated for ankle fractures over a period of 12 months between January and December 2008. results were collated excluding talar and pilon fractures. Emergency department presentation times were noted and time of anaesthetic to determine surgical delay. Notes were reviewed for inpatient stay and postoperative complications. Results: There were 62 male and 83 female patients with a mean age of 49 years. In total, 117 (80%) patients were operated on within 24 hours of presentation (early group). 28 patients’ surgery was delayed beyond 24 hours (delayed group). Of the 117 patients the mean inpatient stay was 3.79 days (± 2.39) whereas in the delayed group the mean stay was 8.57 days (± 6.54). Of the delayed group, 57% of the cases had swelling as the cause of a postponed operation, whereas other causes included lack of theatre time and lack of fitness for surgery. In the early group, 5 patients (4.27%) had wound infections and one patient had a chest infection (0.85%). Four patients (14.28%) from the delayed group developed wound infections all of whom were from patients with ankle swelling. Conclusion: We recommend that policies be put in place to provide early operative intervention for patients with fractured ankles prior to the development of swelling as this would result in improved patient outcome and significant financial savings. If an operation is not feasible within 24 hours of admission and the ankle is swollen resulting in a high operative risk, we recommend sending the patient home for a period of 5–7 days with advice on RICE and anticoagulation which would both permit surgery and cut down costs

Introduction. New methods to reduce inpatient stay, post-operative complications and recovery time are continually being sought in surgery. Many factors affect length of hospital stay, such as, analgesia, patient and surgeon expectations, as well as provision of nursing care and physiotherapy. Development of the use of postoperative local anaesthetic infiltration delivered intra-articularly by a catheter appears to be an effective analgesic method which reduces patient's opioid requirements and allows early physiotherapy without motor blockade of muscles. Our study aimed to explore if the use of local anaesthetic infiltration intra-articularly following joint athroplasty affected the patient's duration of hospitalisation. Methods. Looking retrospectively at arthroplasty audit data, we compared two groups of age and sex-matched patients who underwent primary hip arthroplasty (replacement and resurfacing) and knee arthroplasty performed by a single surgeon using the same surgical techniques. The surgeon began to utilize local anesthetic infiltration intra-articularly in 2009. The first group included patients operated on the year prior to the change and the second group were those operated on within a year of the change of practice. There were 103 patients (27 resurfacings, 28 knees, 48 hips) in the local anaesthetic group and 141 patients (48 resurfacings, 36 knees, 64 hips) in the non-local anaesthetic group. The length of stay was investigated for plausible Normality using the Shapiro Wilks statistic. Between-treatment group differences were examined using one-way analysis of variance (ANOVA). Factors observed were, use of local anaesthetic (yes/no), joint (hip/knee) and day of surgery (weekend/not weekend). Between treatment group differences in gender and complications were investigated using Chi-squared methods. Results. Patients who received local anaesthetic had shorter stays, irrespective of the joint or day of operation. Patients undergoing hip arthroplasty discharged sooner when local anaesthetic was used compared with those without (mean 4.0 days and 4.4 days respectively P=0.04). Patients undergoing knee replacement also discharged sooner when local anaesthetic was used compared with those without (mean 4.9 days and 6.1 days respectively P=0.09). When knee and hip figures were combined and analysed to measure the significance of effects of treatment on the length of stay, local anaesthetic use was found to be statistically significant in reducing length of stay (P=0.01). There were no between-treatment group differences in proportions of complications, gender or day of surgery. Conclusion. The findings of this study highlight that local anaesthetic infiltration reduces duration of in-patient stay following knee and hip joint athroplasty and there is no associated significant increase in immediate post-operative complications

Introduction. Total Hip Replacement (THR) is an effective treatment for end stage degenerative disease of the hip and offers patients the prospect of long term pain relief, improved joint function and quality of life. Enhanced Recovery Programmes (ERP) aim to standardise routine perioperative care, reduce hospital length of stay (LOS) and promote rapid recovery after elective surgery. The aim of this study was to determine whether the implementation of an ERP could successfully reduce the length of hospital stay associated with primary THR and whether this could be achieved without compromising the expected functional outcome or risking an increased dislocation rate. Patients/Materials & Methods. Prospectively collected data on 1161 patients (611 managed with traditional rehabilitation and 550 with ERP) undergoing primary unilateral THR between 2005 and 2013 was retrospectively reviewed. Univariable statistical analysis was undertaken to identify factors that appeared to predict length of stay and a multiple linear regression model was then constructed to determine the significance and strength of effect of the individual predictors. Results. Median LOS was 5 days for those managed in the traditional method and 3 days for those managed with ERP (p<0.001). Multivariate regression models demonstrate that this effect on LOS is independent of and stronger than other factors affecting LOS and we did not observe increased rates of dislocation (1.03% versus 0.73%, p=0.75) or mortality (1.5% versus 0.6%, p=0.14) at one year postoperative in patients managed with ERP. Both groups demonstrated significant improvement in mean Harris Hip Score (+42.8 versus +41.5) at twelve to eighteen months postoperative and there was no significant difference in the magnitude of improvement between groups (p=0.09). Discussion. This is the first study to demonstrate the independent effect of ERP on LOS through multiple regression analysis and to directly compare functional outcomes of patients managed with ERP with the accepted gold standard (traditional rehabilitation) and these findings will be of use to surgeons counselling patients peiroperatively and healthcare planners. Conclusion. Implementation of ERP can reduce the hospital LOS for primary THR without adverse effects on dislocation rates and functional outcomes at 12 to 18 months postoperative

Aim. This study aimed to evaluate the impact on length of hospital stay from dedicated infectious diseases input for orthopaedic infection patients compared to sporadic infection specialist input. Method. We conducted an observational cohort study of 157 adults with orthopaedic infections at a teaching hospital in the UK. The orthopaedic infections included were: osteomyelitis, septic arthritis, infected metalwork and prosthetic joint infections, and adults were aged 18 years or more. Prior to August 2016, advice on orthopaedic infection patients was adhoc with input principally from the on-call infectious diseases registrar and phone calls to microbiology whereas after August 2016 these patients received regular input from dedicated infectious diseases doctor(s). The dedicated input involved bedside reviews, medical management, correct antimicrobial prescribing, managing adverse drug reactions, increased use of outpatient parenteral antimicrobial therapy (OPAT) services especially self-administration of intravenous antibiotics and shared decision-making for treatment failure, whilst remaining under orthopaedic team care. Orthopaedic patients operated on for management of their infection between 29/8/16 and 15/3/17 were prospectively identified and orthopaedic operation records were used to retrospectively identified patients between 29/8/15 and 15/3/16. The length of stay was compared between the 2 groups. Results. There were 83 patients in the dedicated infectious diseases input group (dedicated group) and 74 patients in the sporadic infection specialist input group (sporadic group). The dedicated group were significantly younger: median 58 years versus 69years (p<0.001), and there was a trend to significant differences in the breakdown of diagnosis (p=0.06), but no significant sex difference. The median length of stay for the sporadic group was 20 days (interquartile range (IQR) 13–29 days) compared to 14 days (IQR 9–27 days) for the dedicated group, with a trend to significance (p=0.06) but no effect from age or diagnosis. Our hospital values one day in hospital at £864, therefore over the 6.5 months trial period of the dedicated infectious diseases input there was a cost saving of £430,272 (£864 × 6 days × 83 patients). Conclusions. Dedicated infectious diseases input would be expected to improve patient care but by additionally reducing median length of stay for orthopaedic infection patients, this encourages investment to achieve both. In this era of increased scrutiny of health budgets demonstrating value for money, not just improved quality of patient care, is essential

Aims

The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events.

Introduction

Prosthetic joint infection (PJI) is the leading cause of failure of primary and revision hip and knee arthroplasty. It is challenging condition which represents a growing burden on hospital resources. In-patient hospital stay for antibiotic therapy post-operatively is costly and access to out-patient IV therapy (OPAT) varies between regions. In a tertiary referral centre for revision and infection, the suitability and cost-effectiveness of Dalbavancin was reviewed as a “single-shot” therapy following DAIR or revision lower limb arthroplasty for PJI.

Background. With the recent trend towards enhanced care in joint replacement, it has become increasingly important to identify and address the areas that affect early patient length of stay, while ensuring that practice remains safe. As part of an enhanced care program we conducted two prospective studies of factors delaying discharge following hip replacement in 2006 and 2010. Materials and Methods. In each limb of the study data was collected prospectively daily, by an independent observer, on 100 consecutive primary cemented total hip replacements. Reasons for delay to the discharge and variation from the patient pathway were identified and addressed. Results. The mean length of stay in hospital in 2006 was 4.8 days (target for discharge 4 days) and in 2010, 3.6 days (target for discharge 3 days). In 2006, 31 patients had a stay of more than 4 days, 17 due to inadequate physiotherapy provision, 10 for medical and 4 for other reasons. In 2010, 29 patients had a stay of more than 3 days (though only 15 stayed longer than 4 days), only 2 patients had inadequate physiotherapy provision, in 7 cases discharge was delayed because of need for blood transfusion and 11 because of need for catheterisation. Women, aged more than 70 with preoperative Hemoglobin of less than 12 g/dL were at particularly high risk of requiring transfusion (p = 0.0001). Catheterisation was also identified as a factor causing significant increase in length of stay (p = 0.003). Patients going home in less than 3 days were more likely to have had their operation in the morning. In both studies patients attending the preadmission Joint Group education session were less likely to have a delayed discharge. Discharge was not affected by the type of anesthetic or the experience of the operating surgeon. Conclusions. Patient length of stay is multifactorial and can be continually reduced by close management of patient expectations and incremental identification and improvements in the care pathway. Recommendations. Regular review of a hip replacement care pathway can bring about incremental changes that together have a significant impact on reducing length of stay

Patient controlled analgesia (PCA) is commonly used after TKR. Prolonged use of PCA may however have a negative impact on patients delaying their rehabilitation and therefore discharge. We aimed to evaluate the effect of the duration of PCA on the hospital length of stay (LOS) in patients who undergo TKR. We reviewed the casenotes of all patients who underwent a primary TKR in two South Australian teaching hospitals between 2006 and 2007. After excluding patients whose LOS was determined by placement issues and patients who developed intra-hospital post-operative complications, a number of 345 patients were included in this study. Data collected included: age, gender, ASA grade, regional blocks used, duration of postoperative PCA (< 24 hours, 24-48 hours, > 48 hours) and hospital LOS. Using SAS Version 9.2 statistical analysis software the data was analysed using univariate and multivariate Poisson regression models. Risk ratios, confidence intervals and P values were calculated. Univariate regression models showed that there was a significant difference in length of stay between the three PCA groups (p < 0.0001). Post hoc tests revealed that the length of stay was longer in the 24 to 48 hours and > 48 hours groups compared to the < 24 hours group (p < 0.0001). There was also a significant difference in hospital LOS between males and females (p = 0.0049) with females expected to stay on average 9.7% longer (risk ratio = 1.097, 95% CI 1.028, 1.169). Patients in the ASA categories (1 and 2) recorded shorter lengths of stay than patients in the ASA categories (3 and 4) (p < 0.0001). Also patients treated at one hospital had longer LOS than the patients treated at the other hospital (risk ratio = 1.122, p = 0.0001). There was no evidence for a relationship between the patients' ages, and use or type of regional block used and the hospital LOS. Results from the multivariate regression models showed that each of the four variables found to influence LOS significantly, did so independent of the other variables. Therefore, duration of PCA, gender, ASA and hospital were all independent predictors of hospital LOS after primary TKR. Longer administration of PCA, higher ASA grades and female gender are associated with longer hospital LOS after TKR. Reducing postoperative PCA, as well as improving ASA grading, could reduce LOS in these patients. A multimodal pain management strategy that shortens PCA use could reduce hospital LOS and costs after TKR

The ‘Best Practice Tariff‘ (BPT) was developed to improve hip fracture care by incentivising hospitals to provide timely multidisciplinary care to patients sustaining these injuries. The current literature examining the association between BPT and patient outcomes is conflicting and underpowered. We aimed to determine if achieving BPT has an impact on 30-day mortality and postoperative length of stay.

A retrospective analysis for patients admitted to a major trauma centre (MTC) was performed between 01/01/2013 to 31/12/2020. Data were extracted from the National Hip Fracture Database. The study population was divided into two groups: those who achieved all BPT criteria (BPT-passed) and those who did not (BPT-failed). The primary outcomes of interest included the 30-day mortality rate and postoperative length of stay (LOS). As a secondary objective, we aimed to assess factors that predict perioperative mortality by utilising a logistic regression model.

4397 cases were included for analysis. 3422 (78%) met the BPT criteria, whereas 973 (22%) did not. The mean LOS in the BPT-achieving group was 17.2 days compared with 18.6 in the BPT-failed group, p<0.001. 30-day mortality was significantly lower in the BPT-achieving group i.e., 4.3% in BPT-achieved vs. 12.1% in BPT-failed, p<0.001. Logistic regression modelling demonstrated that attainment of BPT was associated with significantly lower 30-day mortality (OR: 0.32; 95% CI:0.24–0.41; p<0.001).

To our knowledge, this is the largest study to investigate the association between BPT attainment and 30-day mortality as well as the length of stay. The present study demonstrates that achieving BPT in hip fracture patients is associated with a significant reduction in the average length of stay and 30-day mortality rates. Our crude calculations revealed that achieving BPT for 3422 patients earned our hospital trust >£4 million over 8 years. Findings from this study suggest that achieving BPT not only improves 30-day survival in patients with hip fractures but also aids cost-effectiveness by reducing LOS and helps generate NHS Trusts a significant amount of financial reward.

Aims

The primary aim of this study was to investigate the effect of an enhanced recovery program (ERP) on the short-term functional outcome after total hip arthroplasty (THA). Secondary outcomes included its effect on rates of dislocation and mortality.
