Aims. In-hospital length of stay (LOS) and discharge dispositions following arthroplasty could act as surrogate measures for improvement in patient pathways, and have major cost saving implications for healthcare providers. With the ever-growing adoption of robotic technology in arthroplasty, it is imperative to evaluate its impact on LOS. The objectives of this study were to compare LOS and discharge dispositions following robotic arm-assisted total knee arthroplasty (RO TKA) and unicompartmental arthroplasty (RO UKA) versus conventional technique (CO TKA and UKA). Methods. This large-scale, single-institution study included patients of any age undergoing primary TKA (n = 1,375) or UKA (n = 337) for any cause between May 2019 and January 2023. Data extracted included patient demographics, LOS, need for post anaesthesia care unit (PACU) admission, anaesthesia type, readmission within 30 days, and discharge dispositions. Univariate and multivariate logistic regression models were also employed to identify factors and patient characteristics related to delayed discharge. Results. The median LOS in the RO TKA group was 76 hours (interquartile range (IQR) 54 to 104) versus 82.5 (IQR 58 to 127) in the CO TKA group (p < 0.001) and 54 hours (IQR 34 to 77) in the RO UKA versus 58 (IQR 35 to 81) in the CO UKA (p = 0.031). Discharge dispositions were comparable between the two groups. A higher percentage of patients undergoing CO TKA required PACU admission (8% vs 5.2%; p = 0.040). Conclusion. Our study showed that robotic arm assistance was associated with a shorter LOS in patients undergoing primary UKA and TKA, and no difference in the discharge destinations. Our results suggest that robotic arm assistance could be advantageous in partly addressing the upsurge of knee arthroplasty procedures and the concomitant healthcare burden; however, this needs to be corroborated by long-term cost-effectiveness analyses and data from randomized controlled studies.

In-hospital length of stay (LOS) and discharge disposition following arthroplasty could act as surrogate measures for improvement in patient pathways, and have major cost saving implications for healthcare providers. With the ever-growing adoption of robotic technology in arthroplasty, we wished to evaluate its impact on LOS. The objectives of this study were to compare LOS and discharge disposition following robotic-arm assisted (RO THA) versus conventional technique Total Hip Arthroplasty (CO THA). This large-scale, single institution study included patients of any age undergoing primary THA (N = 1,732) for any cause between May 2019 and January 2023. Data extracted included patient demographics, LOS, need for Post Anaesthesia Care Unit (PACU) admission, anaesthesia type, readmission within 30 days and discharge dispositions. Univariate and multivariate logistic regression models were also employed to identify factors and patient characteristics related to delayed discharge. The median LOS in the RO THA group was 54 hours (34, 78) versus 60 (51, 100) in the CO THA group, p<0.001. Discharge disposition was comparable between the two groups. In the multivariate model, age, need for PACU admission, ASA score > 2, female gender, general anaesthesia and utilisation of the conventional technique were significantly associated with LOS > 2 days. Our study showed that robotic-arm assistance was associated with a shorter LOS in patients undergoing primary THA and no difference in discharge destination. Our results suggest that robotic-arm assistance could be advantageous in partly addressing the upsurge of hip arthroplasty procedures and the concomitant health care burden; however, this needs to be corroborated by long-term cost effectiveness analyses and data from randomised controlled studies

Child abuse is an essential discussion within society and poses many challenges. The international literature describes patient and family based risk factors and suspicious injuries. We have created a protocol for the identification and investigation of children with suspected non-accidental injuries. The paediatric orthopaedic ward experiences many children being delayed in the ward once fit for discharge. This study aimed to quanitify those delayed discharges and describe the demographics and risk factors for abuse within the local population. After obtaining ethics clearance, we conducted a retrospective review of records from the Teddy Bear Clinic, as well as admission records. The study examined demographic characteristics, family, injury characteristics and referral to Child Welfare. The delay of discharge from hospital was quantified and was compared to those characteristics. Records were collected from 1 January 2015 to 31 December 2021. Seventy-nine complete records were included. There were 40 males and 39 females with an average age of 20 months. 75.9% were under 36 months old. 94.1% of the cases sustained lower limb fractures. Fifty-two cases had a delayed discharge. The delay ranged from 1 to 233 days. There was an association between an age less than 36 months and delayed discharge. There were no significant correlations between caregiver characteristics and delayed discharge. The later the completion of investigations, the more likely there would be a delay. There was also a significant correlation between referral to Child Welfare and delayed discharge. Children under 36 months on this remain at highest risk for non-accidental injury. Delayed discharge was associated with age less than 36 months, upper limb fractures and referral to Child Welfare. Despite the delayed discharge, most children returned to the same home environments

Hip precautions are currently practiced in three-quarters of trauma hospitals in the UK, despite national recommendations from the ‘Blue Book’ not stating it as a requirement. Valuable therapist time is utilised alongside the need for specialised equipment, which can potentially delay discharge whilst it is being arranged. Objective of this study was to explore the current practice of the use of hip precautions on discharge following hemiarthroplasty for hip fractures. To also explore whether they are necessary and to identify areas for improvement to benefit patient care overall. Online survey distributed to various Trauma and Orthopaedic Departments across the UK. Survey was available over a 4-month period, collecting 55 responses overall. Majority of responses were from trauma and orthopaedic consultants who were aware of the ‘Blue Book’ recommendations. The majority of trusts who responded did not practice hip precautions and did not feel this increased the risk of dislocations on discharge. Recommendations included integration of hip precautions in the post-op advice in coordination with the physiotherapist and information leaflets on discharge regarding hip precautions. Hip precautions were not commonly practiced, for reasons including patient compliance and the inherently stable procedure of a hemiarthroplasty compared to a THR, reducing the need for hip precautions. Hip precautions are not widely regarded as a useful practice for post-hip hemiarthroplasty, viewed as utilising more resources and increasing costs and risk due to increased hospital stay. Thus, this potentially delays discharge overall. A consistent approach should be implemented in treating patients post-hip hemiarthroplasty

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

Same day home (SDH) discharge in total joint arthroplasty (TJA) has increased in popularity in recent years. The objective of this study was to evaluate the causes and predictors of failed discharges in planned SDH patients. A consecutive cohort of patients who underwent total knee (TKA) or total hip arthroplasty (THA) that were scheduled for SDH discharge between April 1, 2019 to March 31, 2021 were retrospectively reviewed. Patient demographics, causes of failed discharge, perioperative variables, 30-day readmissions and 6-month reoperation rates were collected. Multivariate regression analysis was undertaken to identify independent predictors of failed discharge. The cohort consisted of 527 consecutive patients. One hundred and one (19%) patients failed SDH discharge. The leading causes were postoperative hypotension (20%) and patients who were ineligible for the SDH pathway (19%). Two individual surgeons, later operative start time (OR 1.3, 95% CI, 1.15-1.55, p=0.001), ASA class IV (OR 3.4, 95% CI, 1.4-8.2; p=0.006) and undergoing a THA (OR 2.0, 95% CI, 1.2-3.1, p=0.004) were independent predictors of failed SDH discharge. No differences in age, BMI, gender, surgical approach or type of anesthetic were found (p>0.05). The 30-day readmission or 6-month reoperation were similar between groups (p>0.05). Hypotension and inappropriate patient selection were the leading causes of failed SDH discharge. Significant variability existed between individual surgeons failed discharge rates. Patients undergoing a THA, classified as ASA IV or had a later operative start time were all more likely to fail SDH discharge

Introduction. The concept of same-day discharge has garnered increasing significance within orthopedic surgery, particularly in hip and knee procedures. Despite initial concerns surrounding the absence of prolonged hospital care, a burgeoning body of evidence highlights numerous advantages associated with same-day discharge, ranging from mitigating in-hospital infections to offering substantial financial and psychosocial benefits for both patients and healthcare providers. In this study, we aim to scrutinize the trends in same-day discharge specifically within the realm of total hip arthroplasties. Method. This retrospective analysis delves into the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database spanning from 2017 to 2021. Leveraging patient data sourced from the ACS NSQIP database, we sought to elucidate patterns and shifts in same-day discharge practices pertaining to total hip arthroplasties. Result. The preoperative analysis illuminated several notable disparities between patients undergoing same-day hip arthroplasty and those necessitating hospitalization. Notably, same-day hip patients skewed younger, comprising 48.3%females compared to 55.6% in hospitalized hip patients. Furthermore, a lower prevalence of medical comorbidities such as diabetes mellitus (8.5% vs.12.9%), current smoking (9.3% vs. 12.2%), and severe COPD(1.9% vs. 4.1%) was observed among same-day hip group. Operatively, same-day hip surgeries boasted shorter durations, averaging 83.9 minutes, in contrast to the 92.3minutes for hospitalized hip procedures. Postoperatively, same-day hip patients exhibited significantly diminished rates of 30-day readmissions (1.7%vs. 3.5%), procedure-related readmissions (1.0%vs.2.1%), reoperations (1.1%vs.1.9%), and mortality (0.02% vs. 0.04%). Moreover, the prevalence of the same-day discharge concept experienced a remarkable ascent from 2016 to 2021, with rates escalating from 1.5% to 25.6% of all total hip arthroplasties over a span of just six years. Conclusion. In conclusion, same-day discharge is a feasible and safe option for selected THA patients

Introduction. Inpatient rehabilitation services following joint replacement have been estimated to cost over $3 billion/ yr. A shift in reimbursement strategies to bundle payments with the goal of decreasing cost and improving quality has given discharge disposition after joint replacement a front row seat. Our objectives were (1) to establish a correlation between the accuracy of current tools utilized to predict discharge location and (2) compare preoperative and postoperative patient oriented outcomes (POO's) according to discharge disposition. Methods. 188 consecutive total hip arthroplasty (THA) surgeries performed by a single surgeon were prospectively studied. Pre-intervention assessment of the probable and preferred discharge disposition was performed using one of 5 tools (1) experienced surgical coordinator evaluation (2) Risk Assessment and Prediction Tool (RAPT); (3) Charlson Score; (4) ASA Score; and (5) Patient Self-Reported Health Status. Demographic characteristics, Visual Analogue Scale, QWB-7, SF-36, WOMAC, clinical scores were recorded before and after surgery. Correlation between final discharge disposition (home vs rehab) and its predictors was performed. Preoperative and postoperative outcomes were compared, p<0.05 was considered significant. Results. Most accurate predictor of discharge disposition was determined by our experienced surgical coordinator (OR: 11.05; 95% CI of 2.21 to 55.32; p<0.001), followed by the RAPT (OR: 1.56; 95% CI of 1.29 to 1.90; p=0.01). We found a significant difference in age (Rehab: 72.4 SE 1.2 vs Home: 70.3 SE 1.0; p=0.01) and length of stay (Rehab: 3.6 SE 0.01 vs Home: 3.14 SE 0.07; p<0.001) between those discharged to rehab than those discharged home. Mean follow-up time was 2.22 years (range 1–4 years). There was a significant difference between groups on most outcome measures preoperatively (rehab worse than home; p<0.001). Both groups demonstrated significant improvement in all patient perceived outcome measures after THA, but those discharged to rehab continue to report worse scores for the QWB (Rehab: 0.62 SE 0.02 vs Home: 0.67 SE 0.01; p=0.02) and Hip Harris Score (Rehab: 83.07 SE 1.75 vs Home: 88.65 SE 1.31; p=0.01). Discussion. Clinical intuition and personal interaction proved to be the best predictor for discharge disposition. Worse outcomes were observed in patients being discharged to rehab.

Excessive postoperative opioid prescribing is a significant contributor to the opioid crisis. Prescribing in orthopaedic surgery is often further complicated by high use of opioid-based preoperative analgesia. ‘Opioid PrEscRiptions and usage After Surgery’ (OPERAS) is an international multicentre prospective student- and trainee-led collaborative study which aims to quantify the amount of opioids prescribed at discharge after common orthopaedic surgeries against what is consumed by patients at 7-days, and assess the impact of opioids on patient-reported outcomes. Data is being collected over 6 14-day periods on consecutive adult patients undergoing shoulder arthroplasty, rotator cuff repair, shoulder labral repair, anterior cruciate ligament repair, hip arthroplasty, and knee arthroplasty, with follow-up via telephone call at 7-days after discharge. The primary outcome is the proportion of oral morphine equivalents (OME) of prescribed opioids versus consumed opioids at 7-days post-discharge. This ongoing study is actively recruiting in over 20 countries. Globally, 65 centres are collecting orthopaedic, including 10 New Zealand centres and 17 Australian centres. To date, 284 orthopaedic patients have been prospectively enrolled with complete data (mean age 59.6 ± 16.7 years; 51.6% female). Overall, 77% and 89% of patients were prescribed opioids on discharge in New Zealand and Australia respectively. On average, 60% of prescribed opioids were consumed at 7-days post-discharge globally (150 OME (75-500) vs. 90 OME (15-200); p<0.01). In New Zealand and Australia, 42.1% (285 OME (150-584) vs. 120 OME (6-210); p<0.01) and 63.3% (150 OME (86-503) vs. 95 OME (28-221); p<0.01) of prescribed opioids were consumed at 7-days, respectively. OPERAS will provide the first high-quality global data on opioid prescription and consumption patterns with patient perspectives. These data can inform prescribing practice and inform guidelines. The growing interest in New Zealand and Australia in student- and trainee-led orthopaedic collaborative research, as evidenced by this study should be actively encouraged and fostered

There has been significant interest in day-case and rapid discharge pathways for unicompartmental knee replacements (UKR). Pathways to date have shown this to be a safe and feasible option; however, no studies to date have published results of rapid-discharge pathways using the NAVIO robotic system. To date there is no published experience with rapid discharge UKR patients using the NAVIO robotic system. We report an initial experience of 11 patients who have safely been discharged within 24 hours. With the primary goal of investigating factors that led to rapid discharge and a secondary goal of evaluating the safety of doing so. All patients were discharged within 24 hours; there were no post-operative complications and no readmissions to hospital. The mean length of stay was 16.9 hours (SD=7.3), with most patients seen once on average by physiotherapy. Active range of motion at 6 weeks was 0.7o to 130.5 o, with all patients mobilising independently. The average 6-month post-operative Oxford Knee Score was 43.5 out of 48. There were no readmission or complications in any of our patients. This initial feasibility study identified that patients could be safely discharged within 24 hours after UKR using the NAVIO robotic system. With growing uptake of robotic procedures, with longer operative durations than traditional procedures, it is essential to ensure a rapid discharge to reduce healthcare cost whilst ensuring that patients are discharged home in a safe manner

The Trauma Triage clinic (TTC) is a Virtual Fracture clinic which permits the direct discharge of simple, isolated fractures from the Emergency Department (ED), with consultant review of the clinical notes and radiographs. This study details the outcomes of patients with such injuries over a four-year period. All TTC records between January 2014 and December 2017 were collated from a prospective database. Fractures of the radial head, little finger metacarpal, fifth metatarsal, toe phalanges and soft tissue mallet finger injuries were included. Application of the direct discharge protocol, and any deviations were noted. All records were then re-assessed at a minimum of three years after TTC triage (mean 4.5 years) to ascertain which injuries re-attended the trauma clinic, reasons for re-attendance, source of referral and any subsequent surgical procedures. 6709 patients with fractures of the radial head (1882), little finger metacarpal (1621), fifth metatarsal (1916), toe phalanges (920) and soft tissue mallet finger injures (370) were identified. 963 (14%) patients were offered in-person review after TTC, of which 45 (0.6%) underwent a surgical intervention. 299 (4%) re-attended after TTC direct discharge at a mean time after injury of 11.9 weeks and 12 (0.2%) underwent surgical intervention. Serious interventions, defined as those in which a surgical procedure may have been avoided if the patient had not undergone direct discharge, occurred in 1 patient (0.01%). Re-intervention after direct discharge of simple injuries of the elbow, hand and foot is low. Unnecessary deviations from protocol offer avenues to optimise consumption of service resources

Aim. Dalbavancin is a lipoglycopeptide with a half-life of 14 days (range 6.1 to 18.4), significantly longer than other antimicrobials, which avoids the need for daily antibiotic dosing. This multi-centre observational study aims to describe the use of dalbavancin to facilitate discharge in treating bone and joint infections. Method. All adult patients treated with dalbavancin from January 2017 to September 2022 in four UK bone infection units were included. Data collected through a standardised data collection form included:. Clinical and microbiological characteristics. Hospital length of stay. Complications. Patient suitability for hypothetical treatment options, such as Outpatient Parenteral. Antibiotic Team (OPAT). Clinical outcome. Treatment-related costs were calculated for dalbavancin and the preferred hypothetical treatment option that would have been administered for the same duration. The costs were subtracted to calculate the cost difference. Clinical success was defined as the absence of definite failure in accordance with the OVIVA Trial protocol. Results. Thirty-six patients were included: 20 males and 16 females, with a median age of 53 (IQR 43–73): Thirteen were septic arthritis, twelve were prosthetic joints, seven were spondylodiscitis and five were other orthopaedic-related implant infections. In twenty cases the infecting organism was Staphylococcus aureus, fourteen were due to coagulase-negative staphylococci and two no cultured organism. Reasons for dalbavancin. The reasons for choosing dalbavancin over alternatives were due to either:. Necessity due to poor adherence (21), or lack of viable OPAT options due to antibiotic resistance or intolerance (7). OR. Convenience to avoid the need for OPAT (8). Dalbavancin was initiated at 1500mg after a median of 12 days (IQR 6–17) of in-hospital antimicrobial therapy. Subsequent dalbavancin doses were based on clinical decisions and ranged from 1000mg to 1500mg. Healthcare benefits. Switching to dalbavancin reduced treatment costs by a median of £3526 (IQR 1118 - 6251) compared with the preferred theoretical alternatives. A median of 31 hospital days (IQR 23–47) was avoided among patients who would have required a prolonged inpatient stay. Outcome. Overall, 20 patients (55.6%) were successfully treated after a median follow-up of 8 months (IQR, 5.8 – 18.4). No patients developed an adverse drug reaction. Conclusions. Dalbavancin can safely facilitate outpatient treatment in patients with limited oral options and in whom OPAT is unsuitable. Dalbavancin is cost-effective compared with the alternative of an inpatient stay

C-reactive protein (CRP) level is used at our tertiary paediatric hospital in the diagnosis, management, and discharge evaluation of paediatric septic arthritis patients. The purpose of this study was to evaluate the efficacy of a discharge criterion of CRP less than 2 mg/dL for patients with septic arthritis in preventing reoperation and readmission. We also aimed to identify other risk factors of treatment failure. Patients diagnosed with septic arthritis between January 1, 2007 and December 31, 2017 were reviewed retrospectively. The diagnosis of septic arthritis was made based on clinical presentation, laboratory results and the finding of purulent material on joint aspiration or the isolation of a bacterial pathogen from joint fluid or tissue. Bivariate tests of associations between patient or infection factors and readmission and reoperation were performed. Quantitative variables were analyzed using Mann-Whitney tests and categorical variables were analyzed using Chi-square tests. One hundred eighty-three children were included in the study. Seven (3.8%) were readmitted after hospital discharge for further management, including additional advanced imaging, and IV antibiotics. Six (85.7%) of the readmitted patients underwent reoperation. Mean CRP values on presentation were similar between the two groups: 8.26 mg/dL (± 7.87) in the single-admission group and 7.94 mg/dL (± 11.26) in the readmission group (p = 0.430). Mean CRP on discharge for single-admission patients was 1.71 mg/dL (± 1.07), while it was 1.96 mg/dL (± 1.19) for the readmission group (p = 0.664), with a range of < 0 .8 to 6.5 mg/dL and a median of 1.5 mg/dL for the two groups combined. A total of 48 children (25.9%) had CRP values greater than the recommended 2 mg/dL at discharge, though only three of these patients (6.2%) were later readmitted. The only common variable in the readmitted children was either a negative culture result at time of discharge or atypical causative bacteria. CRP values are useful in monitoring treatment efficacy but not as reliable as a discharge criterion to prevent readmission or reoperation in children with septic arthritis. We recommend determining discharge readiness on the basis of clinical improvement and downtrending CRP values. There was a higher risk of readmission in children with an atypical causative bacteria and when culture results were negative at discharge. Close monitoring of these patients after discharge is suggested to identify signs of persistent infection

Aims. The aim of this trial was to assess the cost-effectiveness of a soft bandage and immediate discharge, compared with rigid immobilization, in children aged four to 15 years with a torus fracture of the distal radius. Methods. A within-trial economic evaluation was conducted from the UK NHS and personal social services (PSS) perspective, as well as a broader societal point of view. Health resources and quality of life (the youth version of the EuroQol five-dimension questionnaire (EQ-5D-Y)) data were collected, as part of the Forearm Recovery in Children Evaluation (FORCE) multicentre randomized controlled trial over a six-week period, using trial case report forms and patient-completed questionnaires. Costs and health gains (quality-adjusted life years (QALYs)) were estimated for the two trial treatment groups. Regression was used to estimate the probability of the new treatment being cost-effective at a range of ‘willingness-to-pay’ thresholds, which reflect a range of costs per QALY at which governments are typically prepared to reimburse for treatment. Results. The offer of a soft bandage significantly reduced cost per patient (saving £12.55 (95% confidence interval (CI) -£5.30 to £19.80)) while QALYs were similar (QALY difference between groups: 0.0013 (95% CI -0.0004 to 0.003)). The high probability (95%) that offering a bandage is a cost-effective option was consistent when examining the data in a range of sensitivity analyses. Conclusion. In addition to the known clinical equivalence, this study found that the offer of a bandage reduced cost compared with rigid immobilization among children with a torus fracture of the distal radius. While the cost saving was small for each patient, the high frequency of these injuries indicates a significant saving across the healthcare system.

Introduction. This study was designed to evaluate the effect of discharge timing on 30-day major and minor complications in patients undergoing total knee arthroplasty (TKA) while adjusting for other variables. Methods. Patients 18 years and older undergoing TKA between the years of 2005 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP). Patients whose length of stay (LOS) was >4 days were excluded. Patient demographics, anesthesia type, length of operation and hospital stay, as well as 30-day major and minor complications were collected from the database. Chi square tests were utilized to compare the unadjusted rates of complications between patients whose LOS was 0, 1, 2, and 3–4 days. Multivariable regression was utilized to evaluate the effect of LOS on complication rates, while adjusting for age, American Society of Anesthesiologist (ASA) class, type of anaesthesia, functional status, comorbidities, sex, steroid/immunosuppressant use, body mass index (BMI), diabetes, length of operation and smoking status. Results. A total of 198,191 TKA patients were identified (average age 66 ± 10 years). Average LOS was 2.5 ± 0.81 days. Of these patients, 1,667 (0.84%) were discharged the day of surgery, while 16,186 (8.17%) were discharged one-day post-surgery, 63,540 (32.06%) were discharged on day two, and 115,471 (58.25%) were discharged between 3 and 4 days post-surgery. Unadjusted rates of complications were significantly higher for patients who were discharged on the day of surgery (2.64%), or those whose LOS was 3–4 days (2.78%) compared to those whose LOS was 1 (1.40%) or 2 days (1.67%). After adjusting for all relevant covariables, discharge on the day of surgery increased the risk of major complications by 1.8 (95% Confidence interval [95%CI] 1.2–2.8), and minor complications by 1.6 (95%CI 1.2 – 2.2) compared to patients whose LOS was 2 days. A LOS of 1 day did not affect the risk of major complications compared to a LOS of 2 days, while a LOS of 3–4 days increased the risk of major complications by 1.4 (95%CI 1.3 – 1.6), and minor complications by 1.6 (95%CI 1.4 – 1.7). Regarding specific complications, same-day discharge remained an independent predictor of myocardial infarction (MI), cardiac arrest, pulmonary embolism (PE), unplanned reintubation, >48 hours on ventilator, pneumonia and renal insufficiency, while a LOS of 3–4 days remained an independent predictor of MI, cardiac arrest, sepsis, acute renal failure, PE, unplanned reintubation, >48 hours on ventilator, stroke, deep vein thrombosis, pneumonia, urinary tract infection, renal insufficiency, deep and superficial surgical site infection, and wound disruption compared to patients whose LOS was 2 days (p<0.01). Conclusion. Discharge on days 1–2 postoperatively following TKA appears to have superior outcomes compared to discharge on the day of surgery, or on days 3–4. Prospective clinical data is required to confirm the effect of discharge timing on postoperative outcomes following TKA

INTRODUCTION. Early discharge after total joint arthroplasty has started to gain acceptance in select academic centers. The purpose of this study was to compare the risk of readmission of Medicare patients discharged one day after total knee arthroplasty (TKA), versus those discharged two or three days after surgery. Our hypothesis was that patients with length of stay (LOS) of one day would not have a higher risk of readmission in a community setting. METHODS. A hospital impatient database was queried for all unilateral, primary total knee replacements performed on patients 65 years or older from January 1, 2013 to December 31, 2014. A total of 1,117 patients discharged the day after TKA (reduced LOS) were compared with 947 patients discharged POD #2 or 3 (traditional LOS). All cases were performed at a community-based joint replacement center with rapid recovery protocols. Discharge timing and disposition were based on established functional benchmarks judged by physical therapy. The main outcome measure was all-cause 30-day readmissions. Multivariate logistic regression was used to calculate odds ratio for all cause 30-day readmission for reduced versus traditional LOS while controlling for age, gender, race, diabetes mellitus, ASA score (less than 3 versus 3 or greater), discharge disposition (home versus rehab). RESULTS. The 30-day readmission rate for the reduced LOS group was 1.2%, as compared to 3.4% readmission rate for the traditional LOS group (p=.001). In the regression model, the traditional LOS group had an increased risk of readmission (odds ratio 2.10, 95% CI 1.02–4.35, p=0.045) when controlling for confounding factors. DISCUSSION AND CONCLUSIONS. Medicare patients can be discharged safely the day after total knee arthroplasty with no increased risk of 30-day readmission in a community medical center

Introduction. Due to the opioid epidemic, our service developed a cultural change highlighted by decreasing discharge opioids after lower extremity arthroplasty. However, concern of potentially increasing refill requests exists. As such, the goal of this study was to analyze whether decreased discharge opioids led to increased postoperative opioid refills. Methods. We retrospectively reviewed 19,428 patients undergoing a primary hip or knee arthroplasty at a single institution from 2016–2019. Patients that underwent secondary procedures within that timeframe were excluded. Two-thousand two-hundred and forty-one patients (12%) were on narcotics preoperatively or had chronic pain syndrome. Two reductions in routine discharge narcotics were performed over this timeframe. First, 8,898 patients routinely received 750 morphine milligram equivalents (MMEs). After the first reduction, 4,842 patients routinely received 520 MMEs. After a second reduction, 5,688 patients routinely received 320 MMEs. We analyzed refill rates, refill MMEs, and whether discharge MMEs were associated with refill MMEs in a multivariate model. Results. Opioid refill rates were 28%, 32%, and 33% in each timeframe (p=0.001). Significantly fewer patients received narcotic refills after 6 weeks in the 320 MME group (8%) compared to the 750 MME group (6%, p=0.02). Total refill MMEs reduced significantly from a mean of 282 in the first to 227 in the last timeframe (p<0.001). After controlling for age, sex, BMI, history of anxiety/depression, and procedure type, opioid discharge of <400 MMEs was not a risk factor for increased refill MMEs in opioid-naïve patients (p=0.23). Conclusion. While decrease in MMEs prescribed at discharge after arthroplasty led to a slight increase in the number of opioid refills (5%), there was a reduction in total refill MMEs. Furthermore, less patients received refills beyond 6 weeks postoperatively. This institutional cultural change led to a reduction in opioid prescriptions after primary arthroplasty equivalent to 500,000 oxycodone 5 mg tablets

Myriad protocols exist for isolated Weber B lateral malleolus fractures with a congruent tibiotalar joint on initial radiographs. Stress and weight-bearing radiographs, all at various timepoints, may be employed to identify those injuries that develop significant talar shift but consensus is elusive. This study outlines a safe and reproducible protocol for such injuries, utilising a removable orthosis, immediate weight bearing and standard supine radiographs. A retrospective analysis of a prospective trauma database was analysed to identify patients with an isolated Weber B ankle fracture with adequate presentation radiographs demonstrating a congruent mortise. Patient records and radiographs were evaluated a minimum of 5 years after initial presentation to determine ankle stability, complications, and the burden on outpatient services. Between 2014 and 2016, 657 patients were referred to the specialist trauma clinic from the emergency department. Of the 657, 52 patients had inadequate ED radiographs to determine ankle congruity. At the two-week assessment, 11 of the 52 demonstrated talar shift and required intervention. Therefore 646 patients demonstrated ankle congruity at two weeks after weight bearing. No patient demonstrated talar shift at the six-week assessment. Average number of follow up appointments was 2.4 with 3.5 radiographs. Our new treatment protocol advocates discharge after a single orthopaedic assessment after two weeks of weight bearing. This study supports immediate weight-bearing of Weber B ankle fractures with a congruent mortise in an orthosis. Follow up beyond two weeks is unnecessary and our protocol offers a safe means of significantly reducing the outpatient burden

This aim of this study was to identify common factors in patients with the shortest length of hospital stay following total hip arthroplasty (THA). This would then allow a means of targeting suitable patients to reduce their length of stay. This was a retrospective cohort study of all patients undergoing primary THA at our institution between September 2013 and August 2014. Demographic data were collected from the patient record. The cohort was divided into those discharged to home within two days of operation and the rest of the THA population. The demographics (age, gender, ASA grade, body mass index (BMI), primary diagnosis, socioeconomic status (Scottish Index of Multiple Deprivation, SIMD and SIMD health domain) were compared between groups. In addition for the early discharge group information on comorbidities, family support at home and independent transport were collected. The study cohort was 1292 patients. 119 patients were discharged home on the first post-operative day. Those discharged earlier were on average younger (p<0.0001), more likely to be male (p<0.0001) and had a lower ASA grade (p<0.00001). Other demographics did not differ between groups. Patients who were discharged early also appeared to have few comorbidities (Diabetes 5.9%, Cardiac disease 7.6%, Respiratory disease 9%), high levels of family support at home (95%) and high levels of independent transport arrangements (97%). Factors associated with those patients with the shortest lengths of stay were identified. Such factors could be used to target patients who are suitable for streamlined recovery programmes aimed at early discharge after THA and assist with service planning
