RESUMO
Acute fractures around the hip are prevalent injuries associated with potentially devastating outcomes. The growing utilization of arthroplasty for femoral neck fractures in the elderly is likely a result of improvements in reoperation rates and postoperative function. Compared to hemiarthroplasty, total hip arthroplasty is associated with a slight functional benefit that is unlikely noticeable for many patients, as well as minimal differences in complications and patient reported outcome measures. However, the evidence supporting cement use in femoral stem fixation is robust. Multiple high power randomized controlled trial-based studies indicate cement fixation brings more predictable outcomes and fewer reoperations. In the setting of acute acetabular fracture, total hip arthroplasty is a favorable approach for elderly patients and fracture patterns associated with increased risk of revision after open reduction and internal fixation. Variations in patient characteristics and fracture patterns demand careful consideration whenever selecting the optimal treatment. In fracture patient populations, comanagement is an important consideration when seeking to reduce complications and promote cost-effective quality care.
RESUMO
BACKGROUND: Artificial intelligence in the field of orthopaedics has been a topic of increasing interest and opportunity in recent years. Its applications are widespread both for physicians and patients, including use in clinical decision-making, in the operating room, and in research. In this study, we aimed to assess the quality of ChatGPT answers when asked questions related to total knee arthroplasty. METHODS: ChatGPT prompts were created by turning 15 of the American Academy of Orthopaedic Surgeons Clinical Practice Guidelines into questions. An online survey was created, which included screenshots of each prompt and answers to the 15 questions. Surgeons were asked to grade ChatGPT answers from 1 to 5 based on their characteristics: (1) relevance, (2) accuracy, (3) clarity, (4) completeness, (5) evidence-based, and (6) consistency. There were 11 Adult Joint Reconstruction fellowship-trained surgeons who completed the survey. Questions were subclassified based on the subject of the prompt: (1) risk factors, (2) implant/intraoperative, and (3) pain/functional outcomes. The average and standard deviation for all answers, as well as for each subgroup, were calculated. Inter-rater reliability (IRR) was also calculated. RESULTS: All answer characteristics were graded as being above average (ie, a score > 3). Relevance demonstrated the highest scores (4.43 ± 0.77) by surgeons surveyed, and consistency demonstrated the lowest scores (3.54 ± 1.10). ChatGPT prompts in the Risk Factors group demonstrated the best responses, while those in the Pain/Functional Outcome group demonstrated the lowest. The overall IRR was found to be 0.33 (poor reliability), with the highest IRR for relevance (0.43) and the lowest for evidence-based (0.28). CONCLUSIONS: ChatGPT can answer questions regarding well-established clinical guidelines in total knee arthroplasty with above-average accuracy but demonstrates variable reliability. This investigation is the first step in understanding large language model artificial intelligence like ChatGPT and how well they perform in the field of arthroplasty.

BACKGROUND: Supervised machine learning techniques have been increasingly applied to predict patient outcomes after hip and knee arthroplasty procedures. The purpose of this study was to systematically review the applications of supervised machine learning techniques to predict patient outcomes after primary total hip and knee arthroplasty. METHODS: A comprehensive literature search using the electronic databases MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews was conducted in July of 2021. The inclusion criteria were studies that utilized supervised machine learning techniques to predict patient outcomes after primary total hip or knee arthroplasty. RESULTS: Search criteria yielded n = 30 relevant studies. Topics of study included patient complications (n = 6), readmissions (n = 1), revision (n = 2), patient-reported outcome measures (n = 4), patient satisfaction (n = 4), inpatient status and length of stay (LOS) (n = 9), opioid usage (n = 3), and patient function (n = 1). Studies involved TKA (n = 12), THA (n = 11), or a combination (n = 7). Less than 35% of predictive outcomes had an area under the receiver operating characteristic curve (AUC) in the excellent or outstanding range. Additionally, only 9 of the studies found improvement over logistic regression, and only 9 studies were externally validated. CONCLUSION: Supervised machine learning algorithms are powerful tools that have been increasingly applied to predict patient outcomes after total hip and knee arthroplasty. However, these algorithms should be evaluated in the context of prognostic accuracy, comparison to traditional statistical techniques for outcome prediction, and application to populations outside the training set. While machine learning algorithms have been received with considerable interest, they should be critically assessed and validated prior to clinical adoption.

BACKGROUND: Intra-articular hyaluronic acid (IAHA) has been commonly used in the management of knee osteoarthritis (OA). This study sought to assess patient-reported outcomes (PRO) following different formulations of hyaluronic acid injections for patients who have knee OA. METHODS: A retrospective analysis was performed on patients who have knee OA and received IAHA knee injections from October 2018 to May 2022 in sports medicine (SM) and adult reconstructive (AR) clinics. Patients completed PRO measures including the Patient-Reported Outcome Measurement Information System (PROMIS) Mobility, Pain Interference, and Pain Intensity at baseline, 6-week, 6-month, and 12-month follow-up. Univariate and multivariate analyses were used to evaluate changes in PRO measures between baseline and follow-up periods and to evaluate differences between the SM and AR divisions. A total of 995 patients received IAHA for knee OA and completed PRO assessments. RESULTS: There was no difference in the PROMIS measures based on molecular weight at 6 weeks, 6 months, and 12 months. Except for 6-month Mobility scores between the SM and AR patients (-0.52 ± 5.46 versus 2.03 ± 6.95; P = .02), all other PROMIS scores were similar. Mobility scores at 6 months were significantly different based on Kellgren and Lawrence grade (P = .005), but all other PROMIS scores were similar. CONCLUSION: Average change in PROMIS scores were significantly different only for 6-month Mobility scores based on divisions and Kellgren and Lawrence grade but did not achieve minimally clinical important difference at most timepoints. Further studies are needed to investigate whether improvement is observed in specific patient populations.

BACKGROUND: Removal of primary total knee arthroplasty (TKA) and primary total hip arthroplasty (THA) from the inpatient-only list has financial implications for both patients and institutions. The aim of this study was to evaluate and compare financial parameters between patients designated for inpatient versus outpatient total joint arthroplasty. METHODS: We reviewed all patients who underwent TKA or THA after these procedures were removed from the inpatient-only list. Patients were statistical significance into cohorts based on inpatient or outpatient status, procedure type, and insurance type. This included 5,284 patients, of which 4,279 were designated inpatient while 1,005 were designated outpatient. Patient demographic, perioperative, and financial data including per patient revenues, total and direct costs, and contribution margins (CMs) were collected. Data were compared using t-tests and Chi-squared tests. RESULTS: Among Medicare patients receiving THA, CM was 89.1% lower for the inpatient cohort when compared to outpatient (P < .001), although there was no statistical significance difference between cohorts for TKA (P = .501). Among patients covered by Medicaid or Government-managed plans, CM was 120.8% higher for inpatients receiving THA (P < .001) when compared to outpatients and 136.3% higher for inpatients receiving TKA (P < .001). CONCLUSION: Our analyses showed that recent costs associated with inpatient stay inconsistently match or outpace additional revenue, causing CM to vary drastically depending on insurance and procedure type. For Medicare patients receiving THA, inpatient surgery is financially disincentivized leaving this vulnerable patient population at a risk of losing access to care.

INTRODUCTION: Operating room air quality can be affected by several factors including temperature, humidity, and airborne particle burden. Our study examines the role of operating room (OR) size on air quality and airborne particle (ABP) count in primary total knee arthroplasty (TKA). MATERIALS AND METHODS: We analyzed all primary, elective TKAs performed within two ORs measuring 278 sq ft. (small) and 501 sq ft. (large) at a single academic institution in the United States from April 2019 to June 2020. Intraoperative measurements of temperature, humidity, and ABP count were recorded. p values were calculated using t test for continuous variables and chi-square for categorical values. RESULTS: 91 primary TKA cases were included in the study, with 21 (23.1%) in the small OR and 70 (76.9%) in the large OR. Between-groups comparisons revealed significant differences in relative humidity (small OR 38.5% ± 7.24% vs. large OR 44.4% ± 8.01%, p = 0.002). Significant percent decreases in ABP rates for particles measuring 2.5 µm (- 43.9%, p = 0.007) and 5.0 µm (- 69.0%, p = 0.0024) were found in the large OR. Total time spent in the OR was not significantly different between the two groups (small OR 153.09 ± 22.3 vs. large OR 173 ± 44.6, p = 0.05). CONCLUSIONS: Although total time spent in the room did not differ between the large and small OR, there were significant differences in humidity and ABP rates for particles measuring 2.5 µm and 5.0 µm, suggesting the filtration system encounters less particle burden in larger rooms. Larger studies are required to determine the impact this may have on OR sterility and infection rates.

PURPOSE: The previous literature suggests that 25-30% of patients who undergo total knee arthroplasty (TKA) are using opioids prior to their surgery. This study aims to investigate the effect of preoperative opioid use on clinical outcomes and patient-reported outcome measures (PROMs) following TKA. METHODS: We retrospectively reviewed 329 patients who underwent primary TKA from 2019 to 2020, answered the preoperative opioid survey, and had available PROMs. Patients were stratified into two groups based on whether they were taking opioids preoperatively or not: 26 patients with preoperative opioid use (8%) and 303 patients without preoperative opioid use (92%) were identified. Demographics, clinical data, and PROMs [Forgotten Joint Score (FJS-12), Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR), and Veterans RAND-12 Physical and Mental components (VR-12 PCS and MCS)] were collected. Demographic differences were assessed with Chi-square and independent sample t-tests. Outcomes were compared using multilinear regression analysis, controlling for demographic differences. RESULTS: Preoperative opioid users had a significantly longer length-of-stay (2.74 vs. 2.10; p = 0.010), surgical time (124.65 vs. 105.69; p < 0.001), and were more likely to be African-American (38.5 vs. 14.2%; p = 0.010) compared to preoperative opioid-naive patients. Postoperative FJS-12 did not statistically differ between the two groups. While preoperative KOOS, JR scores were significantly lower for preoperative opioid users (41.10 vs. 46.63; p = 0.043), they did not significantly differ postoperatively. Preoperative VR-12 PCS did not statistically differ between the groups; however, both 3-month (33.87 vs. 38.41; p = 0.049) and 1-year (36.01 vs. 44.73; p = 0.043) scores were significantly lower for preoperative opioid users. Preoperative VR-12 MCS was significantly lower for preoperative opioid users (46.06 vs. 51.06; p = 0.049), though not statistically different postoperatively. CONCLUSION: At 8%, our study population had a lower percentage of opioid users than previously reported in the literature. Preoperative opioid users had longer operative times and length of stay compared to preoperatively opioid-naive patients. While both cohorts achieved similar clinical benefits following TKA, preoperative opioid users reported lower postoperative scores with respect to VR-12 PCS scores.

BACKGROUND: Airborne biologic particles (ABPs) can be measured intraoperatively to evaluate operating room (OR) sterility. Particulate matter (PM) up to 2.5 microns can contain microbial species which may increase infection risk. Our study examines the differences in air quality and ABP count in primary total knee arthroplasty (TKA) and revision TKA (rTKA). METHODS: We analyzed primary and rTKAs in a single OR at an academic institution from January 2020 to December 2020. Procedures from March 15, 2020, to May 4, 2020, were excluded to avoid COVID-related confounding. Temperature, humidity, and ABP count per minute were recorded with a particle counter intraoperatively and cross-referenced with surgical data from the electronic health records using procedure start and end times. Descriptive statistics were used to evaluate the differences in variables. P values were calculated using t-test and chi-square test. RESULTS: A total of 107 TKA cases were included: 79 (73.8%) primary TKAs and 28 (26.2%) rTKAs. Time spent in an OR was significantly higher for rTKAs (primary: 176 ± 46.7 minutes vs revision: 220 ± 47.1 minutes, P < .0001). Compared to primary TKAs, rTKAs had significant percent increases in ABP rates for particles measuring 0.3 µm (+70.4%, P < .001), 0.5 µm (+97.2%, P < .0001), 1.0 µm (+53.2%, P = .001), and 2.5 µm (+30.3%, P = .017) and for PM 2.5 (+108.3%, P < .001) and PM 5.0 (+105.6%, P < .001). CONCLUSION: rTKAs had significantly longer time spent in an OR and significant percent increases in ABP rates for particles measuring 0.3 µm, 0.5 µm, and 1.0 µm compared to primary TKAs. Measurements of PM 2.5 and 5.0 (which can contain large numbers of microbes) were also significantly greater in rTKAs. Further research is needed to determine whether the size and quantity of ABPs translate to higher infection rates after rTKA.

BACKGROUND: Preoperative anemia (POA) is a significant predictor for adverse outcomes in primary total hip arthroplasty (THA). Current literature has studied POA stratified by severity. This study aims to find a threshold preoperative hemoglobin (Hb) value for increased risk of adverse outcomes in THA. METHODS: This is a retrospective analysis of primary THA patients with preoperative Hb values from 2014 to 2021 from an academic orthopedic specialty hospital. Demographics, surgical data, and postoperative outcomes were collected. Patients without preoperative Hb values within the electronic health record system or values acquired >30 days preoperatively were excluded. Patients were grouped based on POA severity using World Health Organization criteria. Secondary analysis using discrete preoperative Hb values was performed. P-values were calculated using analysis of variance/Kruskal-Wallis and chi-squared/Fisher's exact testing with P < .05 considered significant. RESULTS: A total of 1347 patients were included: 771 (57.2%) patients with POA and 576 (42.8%) with normal preoperative Hb. In the POA group, 292 (37.9%) were mild, 445 (57.7%) moderate, and 34 (4.4%) severe. Increased length of stay was seen in moderate (3.9 ± 4.3 vs 2.4 ± 2.1, P < .001) and severe (5.0 ± 3.4 vs 2.4 ± 2.1, P < .0001) groups compared to control. The severe group had higher 90-day readmission and revision rates compared to control. Analysis by discrete Hb values showed increased length of stay in Hb values <11 g/dL and a greater proportion of patients with Hb values <12 g/dL were discharged to skilled nursing facilities. CONCLUSION: Patients with preoperative Hb <12 g/dL should be assessed for other risk factors that may predispose them to postoperative complications. Further investigation is warranted to develop more robust perioperative management strategies for POA patients undergoing THA. LEVEL III EVIDENCE: Retrospective Cohort Study.

BACKGROUND: Regulatory change has created a growing demand to decrease the hospital costs associated with primary total joint arthroplasty (TJA). Concurrently, the removal of lower extremity TJA from the in-patient only list has affected hospital reimbursement. The purpose of this study is to investigate trends in hospital revenue versus costs in primary TJA. METHODS: We retrospectively reviewed all patients who underwent primary TJA from June 2011 to May 2021 at our institution. Patient demographics, revenue, total cost, direct cost, and contribution margin were collected. Changes over time as a percentage of 2011 numbers were analyzed. Linear regression analysis was used to determine overall trend significance and develop projection models. RESULTS: Total knee arthroplasty (TKA) insured by government-managed/Medicaid (GMM) plans showed a significant upward trend (P = .013) in total costs. Direct costs of TKA across all insurance providers (P = .001 and P < .001) and total hip arthroplasty (THA) for Medicare (P = .009) and GMM (P = .001) plans demonstrated significant upward trends. Despite this, 2011-2021 modeling found no significant change in contribution margin for TKA and THA covered under all insurance plans. However, models based on 2018-2021 financial data demonstrated a significant downward trend in contribution margin across Medicare (P < .001) and GMM (P < .001) insurers for both TKA and THA. CONCLUSION: Physician-led innovation in cost-saving strategies has maintained contribution margin over the past decade. However, the increase in direct costs seen over the past few years could lead to negative contribution margins over time, if further efficiency and cost-saving measures are not developed.

BACKGROUND: Patient-reported outcome measures can be used to evaluate post-operative health care quality and patient satisfaction. The Patient's Joint Perception (PJP) question gathers a single patient-reported outcome to measure how patients appraise their joint. This study compares PJP to the Forgotten Joint Score (FJS) at 21 months post-operation to assess its value. METHODS: A retrospective review was performed at an orthopedic specialty hospital for patients who completed both PJP and FJS questionnaires in 2020-2021 and underwent either a unilateral elective primary Total Knee Arthroplasty (TKA) or Total Hip Arthroplasty (THA). Spearman's correlation coefficients and P-values were calculated to determine external validity of PJP. Floor and ceiling effects were analyzed and considered present if ≥ 15% of patients achieved the worst or best score (0-4 for PJP and 0-100 for FJS). RESULTS: In total, 534 patients (327 THA and 207 TKA) were surveyed at 21 months post-operation. External validity against FJS was assessed for both TKA (r = 0.66, P < .01) and THA (r = 0.69, P < .01). For TKA, the floor and ceiling effects were 0.97% and 25.12% for PJP and 3.86% and 4.83% for FJS, respectively. For THA, the floor and ceiling effects were 0.92% and 50.46% for PJP and 2.47% and 20.50% for FJS, respectively. CONCLUSION: The PJP was correlated with FJS moderately for both TKA and THA and can be collected with lesser burden. However, ceiling effects were higher in both TKA and THA for PJP compared to FJS. Further studies are needed to investigate the questionnaires at additional time points and to evaluate the implications of high ceiling effects.

BACKGROUND: Patients who undergo total hip arthroplasty (THA) require resilience to recover and resume daily functions. Increased resilience may be an important factor for achieving improved outcomes. The purpose of this study is to examine the impact of resilience on time to discharge and on early patient-reported outcomes following primary THA. METHODS: A retrospective review of patients who underwent primary THAs and completed the Brief Resilience Scale (BRS) was conducted from 2020 to 2021 at an urban, academic hospital. Patients were separated into 3 cohorts based on BRS score: low (1-2.99), normal (3-4.30), and high (4.31-5) resilience. Demographics, participation in same-day discharge (SDD) program, length of stay (LOS), and preoperative and 3-month postoperative scores on the Hip Disability and Osteoarthritis Outcome Score Joint Replacement (HOOS JR) were assessed. SDD patients were excluded from LOS analysis. RESULTS: A total of 393 patients were included. Compared to low resilience patients, odds of being enrolled in SDD program were 1.49 and 3.01 times higher (P = .01) and 3-month HOOS JR scores improved by 4.7% and 11.7% (P = .03) for normal and high resilience patients, respectively. As resilience increased from low to normal to high in non-SDD patients, LOS significantly decreased (53.27 ± 51.92 vs 38.70 ± 28.03 vs 25.64 ± 14.48 hours, respectively; P = .001). CONCLUSION: Increased resilience is positively associated with likelihood of SDD participation or decreased LOS. Increased resilience was associated with increased HOOS JR scores at 3 months, although this did not reach the minimal clinically important difference. The BRS may be a useful tool for predicting patients who can successfully participate in SDD or predicting LOS after primary THA.

Introduction: Telemedicine is the practice of caring for patients remotely when the patient and provider are not physically present at the same location. Within orthopedic surgery, telemedicine offers care without the typical obstacles of an in-person appointment such as difficulty ambulating following surgery and patient wait times. In this study, we evaluated patient interest and satisfaction in postoperative telemedicine visits following hip or knee arthroplasty surgery. Materials and Methods: Patients were offered either a traditional in-person or a remote telemedicine postoperative visit following surgery. Patients were asked to complete a satisfaction survey following their postoperative visit regarding their experience. Patient-survey responses as well as patient-reported outcome metrics were captured using a mobile and web-based electronic patient rehabilitation application. Results: A total of 766 patients were included in this study with 360 offered postoperative telemedicine visits and 402 offered traditional in-person visits. Two hundred fifty-nine patients reported satisfaction levels with their telemedicine visit, with 58.3% of patients characterizing their feelings with the visit as "extremely satisfied," 32.0% as "satisfied," 8.9% as "neutral," 0.3% as "dissatisfied," and 0.3% as "extremely dissatisfied." A total of 713 patients reported how the COVID-19 pandemic effected their feelings toward telemedicine with 12.9% of patients characterizing the affect as "extremely positively," 33.1% of patients as "positively," 48.9% of patients as "neutral," 3.6% of patients as "negatively," and 1.4% of patients as "extremely negatively." There were no significant differences in the change between preoperative Hip disability and Osteoarthritis Outcome Scores/Knee Injury and Osteoarthritis Outcome Score Joint Replacement, or Veterans RAND 12 Physical and Mental components and these values at 12 weeks follow-up and 1-year follow-up, respectively, in patients who had telemedicine visits versus those who had traditional in-person visits. Discussion: The results of this study demonstrate that the patients who decided to have a telemedicine visit during their postoperative visit were satisfied with their experience. Overall, COVID-19 had a positive influence on patient's feelings toward telemedicine visits.

BACKGROUND: There is debate regarding the benefit of liposomal bupivacaine (LB) as part of a periarticular injection (PAI) in total hip arthroplasty (THA). Here, we evaluate the effect of discontinuing intraoperative LB PAI on immediate postoperative subjective pain, opioid consumption, and objective functional outcomes. METHODS: On July 1, 2019, an institutional policy discontinued the use of intraoperative LB PAI. A consecutive cohort that received LB PAI and a subsequent cohort that did not were compared. All patients received the same opioid-sparing protocol. Nursing documented verbal rating scale pain scores were averaged per patient per 12-hour interval. Opiate administration events were converted into morphine milligram equivalences per patient per 24-hour interval. The validated Activity Measure for Postacute Care (AM-PAC) tool was used to evaluate functional outcomes. RESULTS: Six hundred thirty eight primary THAs received LB followed by 939 that did not. In the non-LB THAs, BMI was higher (30.06 vs 29.43; P < .05). Besides marital status, the remaining baseline demographics were similar between the two cohorts (P > .05). The non-LB THA cohort demonstrated a marginal increase in verbal rating scale pain scores between 12 to 24 hours (4.42 ± 1.70 vs 4.20 ± 1.87; P < .05) and 36 to 48 hours (4.49 ± 1.72 vs 4.21 ± 1.83; P < .05). There was no difference in inpatient opioid administration up to 96 hours postoperatively (P > .05) or AM-PAC functional scores within the first 24 hours (P > .05). CONCLUSION: A small statistical, but not clinically meaningful, difference was observed in subjective pain scores with LB PAI discontinuation. Opioid consumption and postoperative AM-PAC functional scores were unchanged after LB PAI discontinuation.

BACKGROUND: Medicare's Bundled Payments for Care Initiative (BPCI) is a risk-sharing alternative payment model. There is a concern that BPCI providers may avoid operating on obese patients and active smokers to reduce costs. We sought to understand if increased focus on these patient factors has led to a change in patient demographics in Medicare-insured patients undergoing total knee arthroplasty (TKA). METHODS: We retrospectively reviewed all patients who underwent TKA at an academic orthopedic specialty hospital between 1/1/13 and 8/31/19. Surgical date, insurance provider, BMI, and smoking status were collected. Patients were categorized as a current, former, or never smoker. Patients were categorized as obese if their BMI was >30 kg/m2, morbidly obese if their BMI was >40 kg/m2, and super obese if their BMI was >50 kg/m2. RESULTS: In total, 10,979 patients with complete insurance information were analyzed. There was no statistically significant change in the proportion of Medicare patients who were active smokers (4.34% in 2013, 4.85% in 2019, Pearson correlation coefficient = 0.6092, P = .146). The proportion of Medicare patients with BMI >30 kg/m2 increased over the study period (35.84% in 2013, 55.77% in 2019, Pearson correlation coefficient = 0.8505, P = .015). When looking at patients with BMI >40 kg/m2 and >50 kg/m2, there was no significant change. CONCLUSIONS: Despite concern that reimbursement payments could alter access to care for patients with certain risk factors, this study did not find a noticeable difference in the representation of patients with obesity and smoking status undergoing TKA following the installation of BPCI. LEVEL OF EVIDENCE: III, retrospective observational analysis.

BACKGROUND: The use of perioperative adductor canal blocks (PABs) continues to be a highly debated topic for total knee arthroplasty (TKA). Here, we evaluate the effect of PABs on immediate postoperative subjective pain scores, opioid consumption, and objective functional outcomes. METHODS: On December 1, 2019, an institution-wide policy change was begun to use PABs in primary elective TKAs. Patient demographics, immediate postoperative nursing documented pain scores, opioid administration events, and validated physical therapy functional scores were prospectively collected as part of the standard of care and retrospectively queried through our electronic data warehouse. A historical comparison cohort was derived from consecutive patients undergoing TKA between July 1, 2019 and November 30, 2019. RESULTS: 405 primary TKAs received PABs, while 789 patients were in the control cohort. Compared with controls, average verbal rating scale pain scores were lower among PAB recipients from 0-12 hours (2.42 ± 1.60 vs 2.05 ± 1.60; <.001) and 24-36 hours (4.92 ± 2.00 vs 4.47 ± 2.27; <.01). PAB recipients demonstrated significantly lower opioid consumption within the first 24 hours (44.34 ± 40.98 vs 36.83 ± 48.13; P < .01) and during their total inpatient stay (92.27 ± 109.81 vs 77.52 ± 123.11; <.05). AM-PAC scores within the first 24 hours were also higher for PABs (total scores: 20.28 ± 3.06 vs 20.71 ± 3.12; <.05). CONCLUSION: While the minimal clinically important differences in pain scores and functional status were comparable between both cohorts, patients demonstrated a significant reduction in overall inpatient opiate consumption after the introduction of PABs. Surgeons should consider these findings when evaluating for perioperative pain management, opioid-sparing, and rapid discharge protocols.

BACKGROUND: Opioids have played an important part in post-operative analgesia, but concerns with associated morbidity and the fate of leftover pills have prompted the creation of opioid-sparing protocols. The purpose of this study is to investigate the impact of the implementation of an opioid-sparing protocol on survey-based patient satisfaction scores following total hip arthroplasty (THA). METHODS: This study is a retrospective review of prospectively collected data on patients who underwent primary THA between November 2014 and July 2019. Inclusion criteria consisted of primary elective THA with complete Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey information. Cohorts were separated based on their date of surgery relative to the start of an institutional opioid-sparing-protocol in October 2018. Discharge prescriptions and refills were recorded on chart review and converted to milligram morphine equivalents (MME) for comparison between different opioids. HCAHPS results were analyzed for percentage of "top box" ratings for comparison between the 2 groups. RESULTS: In total, 1003 patients met inclusion criteria: 804 pre-protocol and 199 post-protocol. Mean length of stay decreased from 1.74 ± 1.03 to 1.50 ± 1.11 days (P < .001). Pre-operative Visual Analog Scale pain decreased from 7.00 ± 2.30 to 6.41 ± 2.66 (P = .011) as did the rate of opioid refills (15.6%-9.1%; P = .019). Quantity of opioid medication prescribed upon discharge also decreased from 432 ± 298 to 114 ± 156 MME (P < .001). There was no change in "top box percentages" for satisfaction with pain control (79.7% pre-protocol, 82.1% post-protocol; P = .767). There was a significant increase in proportion of patients reporting top box satisfaction with their overall surgical experience after protocol implementation (88.2%-94.0%; P = .018). CONCLUSION: A reduction in opioids prescribed after THA is not associated with a decrease in patient satisfaction with regard to pain control, as measured by the HCAHPS survey, nor is it associated with an increase in post-operative opioid refills. LOE: III. CLINICAL RELEVANCE: This study suggests that HCAHP scores are not negatively impacted by a reduction in post-operative opioid analgesics.

BACKGROUND: Vancomycin is often used as antimicrobial prophylaxis in patients undergoing total hip or knee arthroplasty. Vancomycin requires longer infusion times to avoid associated side effects. We hypothesized that vancomycin infusion is often started too late and that delayed infusion may predispose patients to increased rates of surgical site infections and prosthetic joint infections. METHODS: We reviewed clinical data for all primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients at our institution between 2013 and 2020 who received intravenous vancomycin as primary perioperative gram-positive antibiotic prophylaxis. We calculated duration of infusion before incision or tourniquet inflation, with a cutoff of 30 minutes defining adequate administration. Patients were divided into two groups: 1) appropriate administration and 2) incomplete administration. Surgical factors and quality outcomes were compared between groups. RESULTS: We reviewed 1047 primary THA and TKA patients (524 THAs and 523 TKAs). The indication for intravenous vancomycin usage was allergy (61%), methicillin-resistant staphylococcus aureus colonization (17%), both allergy and colonization (14%), and other (8%). 50.4% of patients began infusion >30 minutes preoperatively (group A), and 49.6% began infusion <30 minutes preoperatively (group B). Group B had significantly higher rates of readmissions for infectious causes (3.6 vs 1.3%, P = .017). This included a statistically significant increase in confirmed prosthetic joint infections (2.2% vs 0.6%, P = .023). Regression analysis confirmed <30 minutes of vancomycin infusion as an independent risk factor for PJI when controlling for comorbidities (OR 5.22, P = .012). CONCLUSION: Late infusion of vancomycin is common and associated with increased rates of infectious causes for readmission and PJI. Preoperative protocols should be created to ensure appropriate vancomycin administration when indicated.

BACKGROUND: Alternative payment models were set up to increase the value of care for total joint arthroplasty. Currently, total knee arthroplasty (TKA) and total hip arthroplasty (THA) are reimbursed within the same bundle. We sought to determine whether it was appropriate for these cases to be included within the same bundle. METHODS: The data were collected from consecutive patients in a bundled payment program at a single large academic institution. All payments for 90 days postoperatively were included in the episode of care. Readmission rates, demographics, and length of stay were collected for each episode of care. RESULTS: There was a significant difference in cost of episode of care between TKA and THA, with the average TKA episode-of-care cost being higher than the average THA episode-of-care cost ($25803 vs $23805, P < .0001). There was a statistically significant difference between the 2 groups between gender, race, medical complexity, disposition outcome, and length of stay. The TKA group trended toward a lower readmission rate (5.3%) compared to the THA group (6.6%). CONCLUSION: The cost of an episode of care for patients within the bundled payment model is significantly higher for patients undergoing TKA compared with those undergoing a THA. This should be taken into consideration when determining payment plans for patients in alternative payment plans, along with other aspects of risk that need to be considered in order to allow for hospitals to be successful under the bundled payment model.

As the world grapples with the COVID-19 pandemic, we as health care professionals thrive to continue to help our patients, and as orthopedic surgeons, this goal is ever more challenging. As part of a major academic tertiary medical center in New York City, the orthopedic department at New York University (NYU) Langone Health has evolved and adapted to meet the challenges of the COVID pandemic. In our report, we will detail the different aspects and actions taken by NYU Langone Health as well as NYU Langone Orthopedic Hospital and the orthopedic department in particular. Among the steps taken, the department has reconfigured its staff's assignments to help both with the institution's efforts and our patients' needs from reassigning operating room nurses to medical COVID floors to having attending surgeons cover urgent care locations. We have reorganized our residency and fellowship rotations and assignments as well as adapting our educational programs to online learning. While constantly evolving to meet the institution's and our patient demands, our leadership starts planning for the return to a new "normal".
