RESUMO
Proper predictive tools are essential to guide patient selection, optimization, category of surgical admission (inpatient, outpatient surgery), and discharge disposition, and predict the risk of readmissions and complications after orthopaedic procedures. Therefore, identification and optimization of patients' perioperative risk for surgery is essential, and understanding these basic concepts is crucial to maximizing patient care quality. It is important to define risk, stratify the existing preoperative attributes, and review key concepts of patient-specific risk calculation and documentation.

PURPOSE: This study aimed to evaluate the safety of total knee arthroplasty (TKA) in Jehovah's Witness patients compared to non-Jehovah's Witness patients using standard peri-operative TKA protocols as well as assess the role of tranexamic acid (TXA) in managing blood loss in this population. METHODS: Patients undergoing TKA between 2011 and 2021 at two tertiary academic centers were retrospectively reviewed. Patient demographics, pre- and post-operative hematologic laboratory values, intra-operative tranexamic acid use, 90-day post-operative complications, and subsequent revisions were collected. These variables were then compared between propensity score-matched cohorts at a 2:1 ratio of those who did not identify as Jehovah's Witness to those who did. Regression analysis was used to determine the effect of intraoperative TXA on hemoglobin (hgb) shift. RESULTS: After applying exclusion criteria and matching, the TKA outcomes of 316 non-Jehovah's Witness patients and 152 Jehovah's Witness patients were analyzed. Univariate analysis suggested that non-Jehovah's Witness patients and Jehovah's Witness patients had similar pre- and post-operative hgb, hgb shift, and hematocrit (hct). Only 1 (0.8%) Jehovah's Witness patient reached a hgb < 8.0 mg/dL post-operatively. Multivariate logistic regression suggested that Jehovah's Witness patients did not have increased odds of reaching a hgb < 8.0 mg/dL (odds ratio [OR] = 0.99 [0.96, 1.02]; P = 0.42). Multivariate linear regression suggested that intra-operative TXA was positively correlated with hgb shift and thus a smaller decrease in hgb from pre- to post-TKA (ß = 0.38 [0.06, 0.69]; P = 0.02). Additionally, Jehovah's Witness patients had excellent revision-free (95% [91, 99]) and infection-free (98% [95, 100]) survival at 8 years. CONCLUSION: Standard peri-operative TKA protocols are safe for Jehovah's Witness patients who do not have the need for transfusion, especially with appropriate pre-operative hgb levels and the use of intra-operative TXA. Furthermore, these patients have excellent survivorship at 5 and 8 years follow-up.
RESUMO
BACKGROUND: Utilization of total knee arthroplasty (TKA) continues to rise among patients who have a high comorbidity burden (HCB). With changes in reimbursement models over the past decade, it is essential to assess the financial impact of HCB TKA on healthcare systems. This study aimed to examine trends in revenue and costs associated with TKA in HCB patients over time. METHODS: Of 14,978 TKA performed at a large, urban academic medical center between 2013 and 2021, we retrospectively analyzed HCB patients (Charlson comorbidity index ≥ 5 and American Society of Anesthesiology scores of 3 or 4). A total of 1,156 HCB TKA patients who had complete financial data were identified. Patient demographics, perioperative data, revenue, costs, and contribution margin were collected for each patient. Changes in these financial values over time, as a percentage of 2013 values, were analyzed. Linear regression was performed with a trend analysis to determine significance. RESULTS: From 2013 to 2021, the percentage of HCB TKAs per year increased from 4.2% in 2013 to 16.5% in 2021 (P < .001). The revenue of TKA in HCB patients remained steady (P = .093), while direct costs increased significantly (32.0%; P = .015), resulting in a decline of contribution margin to a low of 82.3% of 2013 margins. There was no significant change in rates of 90-day complications or home discharge following HCB TKA during the study period. CONCLUSIONS: The results of this study indicate a major rise in cost for TKA among HCB patients, without a corresponding rise in revenue. As more patients who have HCB become candidates for TKA, the negative financial impact on institutions should be considered, as payments to institutions do not adequately reflect patient complexity. A re-evaluation of institutional payments for medically complex TKA patients is warranted to maintain patient access among at-need populations.
RESUMO
BACKGROUND: Since 2021, the Centers for Medicare and Medicaid Services have mandated that patients have open access to their medical records. Many institutions use online portals, which allow patients to access their health information and communicate with care teams. Our research aimed to evaluate demographic patterns for online patient portal utilization in patients undergoing total knee arthroplasty (TKA). Further, we assessed if and how portal engagement contributes to perioperative outcomes. METHODS: This study retrospectively reviewed primary and elective TKA from 2017 to 2022 at a single academic institution. Patients were stratified into 2 groups based on their online portal status: activated (A) or not-activated (NA). Baseline characteristics and postoperative outcomes were collected from the electronic medical record and compared. RESULTS: In total, 10,995 patients were included: 8,330 (75.8%) were A and 2,625 (24.2%) were NA. The NA group was significantly older (P < .001); more likely to be Black (P < .001), women (P < .001), single/divorced/widowed (P < .001), non-English speaking (P < .001), and Medicare or Medicaid insured (P < .001); from zip codes with median incomes below $50,000 (P < .001), and more likely to be American Society of Anesthesiologists class III or IV (P < .001). Patient-reported outcome measure completion rates were significantly lower in the NA group (15.3 versus 47.7%, P < .001). Lengths of stay (LOS) were significantly higher in the NA group (2.7 versus 2.1 days, P < .001). The NA group was significantly more likely to be discharged to skilled nursing facilities (P < .001). Comparable rates of 90-day emergency department visits, readmissions, as well as 90-day and 2-year revisions, were observed across groups. CONCLUSIONS: There are significant disparities in online portal activation status based on patient demographics. Patients who have A portals had significantly higher Patient-reported outcome measure completion rates, shorter LOS, and higher rates of home discharge. Further research should determine which other factors may affect patient portal utilization and inform interventions to improve portal utilization among minority populations.
RESUMO
BACKGROUND: Liver cirrhosis is associated with increased perioperative morbidity. Our study used the Model for End-Stage Liver Disease (MELD) score to assess the impact of cirrhosis severity on postoperative outcomes following total knee arthroplasty (TKA). METHODS: A retrospective review identified 59 patients with liver cirrhosis who underwent primary TKA at a large, urban, academic center from January 2013 to August 2022. Cirrhosis was categorized as mild (MELD < 10; n = 47) or moderate-severe (MELD ≥ 10; n = 12). Modified Clavien-Dindo classification was used to grade complications, where grade 2+ denoted significant intervention. Hospital length of stay, nonhome discharge, and mortality were collected. A 1:1 propensity matching was used to control for demographics and selected comorbidities. RESULTS: Moderate-severe cirrhosis was associated with significantly higher rates of intrahospital overall (58.33 versus 16.67%, P = .036) complications, 30-day overall complications (75 versus 33.33%, P = .042), and 90-day overall complications (75 versus 33.33%, P = .042) when compared to matched mild cirrhosis patients. Compared to matched noncirrhotic controls, mild cirrhosis patients had no significant increase in complication rate or other outcomes (P > .05). CONCLUSIONS: Patients with moderate-severe liver cirrhosis are at risk of short-term complications following primary TKA. Patients with mild cirrhosis have comparable outcomes to matched noncirrhotic patients. Surgeons can use MELD score prior to scheduling TKA to determine which patients require optimization or higher levels of perioperative care.

BACKGROUND: The direct anterior approach (DAA) and posterior approach (PA) for total hip arthroplasty (THA) have advantages and disadvantages, but their physiologic burden to the surgeon has not been quantified. This study was conducted to determine whether differences exist in surgeon physiological stress and strain during DAA in comparison to PA. METHODS: We evaluated a prospective cohort of 144 consecutive cases (67 DAA and 77 PA). There were 5, high-volume, fellowship-trained arthroplasty surgeons who wore a smart-vest that recorded cardiorespiratory data while performing primary THA DAA or PA. Heart rate (beats/minute), stress index (correlates with sympathetic activations), respiratory rate (respirations/minute), minute ventilation (L/min), and energy expenditure (calories) were recorded, along with patient body mass index and operative time. Continuous data was compared using t-tests or Mann Whitney U tests, and categorical data was compared with Chi-square or Fischer's exact tests. RESULTS: There were no differences in patient characteristics. Compared to PA, performing THA via DAA had a significantly higher surgeon stress index (17.4 versus 12.4; P < .001), heart rate (101 versus 98.3; P = .007), minute ventilation (21.7 versus 18.7; P < .001), and energy expenditure per hour (349 versus 295; P < .001). However, DAA had a significantly shorter operative time (71.4 versus 82.1; P = .001). CONCLUSIONS: Surgeons experience significantly higher physiological stress and strain when performing DAA compared to PA for primary THA. This study provides objective data on energy expenditure that can be factored into choice of approach, case order, and scheduling preferences, and provides insight into the work done by the surgeon.
RESUMO
BACKGROUND: As worldwide utilization of total knee arthroplasty (TKA) broadens, demographic trends can help make projections to inform access to care. This study aimed to assess the temporal trends in the socioeconomic and medical demographics of patients undergoing TKA. METHODS: A retrospective review of 15,848 patients who underwent primary, elective TKA at an urban, New York City-based academic medical center between January 2013 and September 2022 was performed. Trends in patients' age, body mass index (BMI), socioeconomic status (SES) (based on median income by patients' ZIP code), race, and Charlson comorbidity index were evaluated using the Mann-Kendall test. RESULTS: In the last decade, mean patient age (65 to 68 years, P < .001) and Charlson comorbidity index (1.4 to 2.3, P < .001) increased significantly. The proportion of patients who had a BMI ≥ 30 and < 40 increased (43.8 to 51.2%, P = .002), while the proportion of patients who had a BMI ≥ 40 (13.7 to 12.1%, P = .015) and BMI < 30 (42.5 to 36.8%, P = .020) decreased. The distribution of patients' race and SES did not change from 2013 to 2022; Black (18.1 to 16.8%, P = .211) and low SES (12.9 to 11.3%, P = .283) patients consistently represented a minority of TKA patients. CONCLUSIONS: Over the last decade, the average age and comorbidity burden of TKA patients at our institution have increased. This portends the need for higher levels of preoperative optimization and postoperative management for TKA patients. A decreased prevalence of BMI ≥40 could reflect optimization efforts. However, the consistently low prevalence of Black and low-SES patients suggests that recent payment models did not improve access to care for these populations. LEVEL OF EVIDENCE: IV.

BACKGROUND: Financial analyses of simultaneous bilateral total knee arthroplasty versus staged bilateral total knee arthroplasty (simBTKA and staBTKA, respectively) have shown improved cost-effectiveness of simBTKA, though revenue and contribution margin (CM) for these procedures have not been investigated. Our analyses compared surgical outcomes, revenues, and CMs between simBTKA and staBTKA. METHODS: We retrospectively reviewed all patients who underwent simBTKA (both procedures done on the same day) and staBTKA (procedures done on a different day within one year) between 2012 and 2021. Patients were 1:1 propensity matched based on baseline characteristics. Surgical outcomes, as well as revenue, cost, and CM of the inpatient episode were compared between groups. Of the 2,357 patients evaluated (n = 595 simBTKA, n = 1,762 staBTKA), 410 were included in final matched analyses (205 per group). RESULTS: Total (P < .001) and direct (P < .001) costs were significantly lower for simBTKA procedures compared to overall costs of both staBTKA procedures. Significantly lower revenue for simBTKA procedures (P < .001), resulted in comparable CM between groups (P = .477). Postoperative complications including 90-day readmission (P = 1.000), 90-day revision (P = 1.000) and all-cause revision at latest follow-up (P = .083) were similar between groups. CONCLUSIONS: In our propensity-matched cohort, lower costs for simBTKA compared to staBTKA were matched by lower revenues, with a resulting similar CM between procedures. Given that postoperative complication rates were similar, both procedures had comparable cost-effectiveness. Future research is needed to identify patients for whom simBTKA may represent a better surgical intervention compared to staBTKA with respect to clinical and patient reported outcomes.

BACKGROUND: Debridement, antibiotics, and implant retention (DAIR) are the mainstays surgical treatment for acute periprosthetic joint infection (PJI). However, reoperation following DAIR is common and the risk factors for DAIR failure remain unclear. This study aimed to assess the perioperative characteristics of patients who failed initial DAIR treatment. METHODS: A retrospective review was conducted on 83 patients who underwent DAIR for acute PJI within 3 months following index surgery from 2011 to 2022, with a minimum one-year follow-up. Surgical outcomes were categorized using the Musculoskeletal Infection Society outcome reporting tool (Tiers 1 to 4). Patient demographics, laboratory data, and perioperative outcomes were compared between patients who had failed (Tiers 3 and 4) (n = 32) and successful (Tiers 1 and 2) (n = 51) DAIR treatment. Logistic regression was also performed. RESULTS: After logistic regression, Charlson Comorbidity Index (odds ratio [OR]: 1.57; P = .003), preoperative C-reactive protein (OR: 1.06; P = .014), synovial white blood cell (OR: 1.14; P = .008), and polymorphonuclear cell (PMN%) counts (OR: 1.05; P = .015) were independently associated with failed DAIR. Compared with total hip arthroplasty, total knee arthroplasty patients (OR: 6.08; P = .001) were at increased risk of DAIR failure. The type of organism and time from primary surgery were not correlated with DAIR failure. CONCLUSIONS: Patients who had failed initial DAIR tended to have significantly higher Charlson Comorbidity Index, C-reactive protein, synovial white blood cell, and PMN%. The total knee arthroplasty DAIRs were more likely to fail than the total hip arthroplasty DAIRs. These characteristics should be considered when planning acute PJI management, as certain patients may be at higher risk for DAIR failure and may benefit from other surgical treatments. LEVEL OF EVIDENCE: III.
RESUMO
INTRODUCTION: Following removal of total hip arthroplasty (THA) from the inpatient only (IPO) list by the Center for Medicare Services (CMS), arthroplasty surgeons face increased pressure to perform procedures on an outpatient (OP) basis. The purposes of the present study were to compare patients booked for THA as OP who required conversion to IP status postoperatively, to patients who were booked as, and remained OP, and to identify factors predictive of conversion from OP to IP status. METHODS: We retrospectively reviewed all patients who underwent a primary THA at our institution between January 1, 2020 and April 26, 2022. All patients included were originally scheduled for OP surgery and were separated based on conversion to IP status postoperatively. Multiple regression analyses were used to determine the significance of all perioperative variables. Modeling via binary logistic regressions were used to determine factors predictive of status conversion. RESULTS: Of 1,937 patients, 372 (19.2%) designated as OP preoperatively required conversion to IP status postoperatively. These patients had significantly higher facility discharge rates (P < 0.001) and 90-day readmission rates (P = 0.024). Patients aged 65 and older (P < 0.001), females (P < 0.001), patients with Black/African American race (P = 0.027), with a recovery room arrival time after 12 pm (P < 0.001), with a BMI > 30 kg/m2 (P = 0.001), and with a Charlson Comorbidity Index (CCI) ≥ 4 (P = 0.013) were Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation more likely to require conversion to IP designation. Marital status and time of procedure were also significant factors, as patients who were married (P < 0.001) and who were the first case of the day (P < 0.001) were less likely to be converted to IP. CONCLUSION: Several factors were identified which could help determine appropriate hospital designation status at the time of surgical booking to ultimately avoid insurance claim denials. These included BMI, certain demographic factors, CCI ≥ 4, and patients 65 or older. LEVEL III EVIDENCE: Retrospective Cohort Study.
RESUMO
INTRODUCTION: While increased body mass index (BMI) in patients undergoing total hip arthroplasty (THA) increases surgical complexity, there is a paucity of objective studies assessing the impact of patient BMI on the cardiovascular stress experienced by surgeons during THA. The aim of this study was to assess the impact of patient BMI on surgeon cardiovascular strain during THA. METHODS: We prospectively evaluated three fellowship-trained arthroplasty surgeons performing a total of 115 THAs. A smart-vest worn by the surgeons recorded mean heart rate, stress index (correlate of sympathetic activation), respiratory rate, minute ventilation, and energy expenditure throughout the procedures. Patient demographics as well as perioperative data including surgical approach, surgery duration, number of assistants, and the timing of the surgery during the day were collected. Linear regression was utilized to assess the impact of patient characteristics and perioperative data on cardiorespiratory metrics. RESULTS: Average surgeon heart rate, energy expenditure, and stress index during surgery were 98.50 beats/min, 309.49 cal/h, and 14.10, respectively. Higher patient BMI was significantly associated with increased hourly energy expenditure (P = 0.027), mean heart rate (P = 0.037), and stress index (P = 0.027) independent of surgical approach. Respiratory rate and minute ventilation were not associated with patient BMI. The number of assistants and time of surgery during the day did not impact cardiorespiratory strain on the surgeon. CONCLUSION: The physiologic burden on surgeons during primary THA significantly increases as patient BMI increases. This study suggests that healthcare systems should consider adjusting reimbursement models to account for increased surgeon workload due to obesity. Further surgeons should adopt strategies in operative planning and case scheduling to handle this added physical strain. LEVEL OF EVIDENCE: III.

INTRODUCTION: Optimizing operating room (OR) scheduling accuracy is important for OR efficiency, meeting patient expectations, and maximizing value for health systems. However, limited data exist on factors influencing the precision of Total Hip Arthroplasty (THA) OR scheduling. This study aims to identify the factors influencing the accuracy of OR scheduling for THA. METHODS: A retrospective review of 6,072 THA (5,579 primary THA and 493 revision THA) performed between January 2020 and May 2023 at an urban, academic institution was conducted. We collected baseline patient characteristics, surgeon years of experience, and compared actual wheels in to wheels out (WIWO) OR time against scheduled OR time. Significant scheduling inaccuracies were defined as actual OR times deviating by at least 15% from scheduled OR times. Logistic regression analyses were employed to assess the impact of patient, surgeon, and intraoperative factors on OR scheduling accuracy. RESULTS: Using adjusted odds ratios, primary THA patients who had a lower BMI and surgeons who had less than 10 years of experience were associated with overestimation of OR time. Whereas, higher BMI, younger age, general anesthesia, non-primary osteoarthritis indications, and afternoon procedure start times were linked to underestimation of OR time. For revision THA, lower BMI and fewer components revised correlated with overestimated OR time. Men, higher BMI, more components revised, septic indication for surgery, and morning procedure start times were associated with underestimation of OR time. CONCLUSION: This study highlights several critical patient, surgeon, and intraoperative factors influencing OR scheduling accuracy for THA. OR scheduling models should consider these factors to enhance OR efficiency.

BACKGROUND: Over the past decade, reimbursement models and target payments have been modified in an effort to decrease costs of revision total knee arthroplasty (rTKA) while maintaining the quality of care. The goal of this study was to investigate trends in revenue and costs associated with rTKA. METHODS: We retrospectively reviewed all patients who underwent rTKA between 2011 and 2021 at our institution. Patients were stratified into groups based on insurance coverage: Medicare, government-managed or Medicaid (GMM), or commercial insurance. Patient demographics were collected, as well as revenue, costs, and contribution margin (CM) of the inpatient episode. Changes over time as a percentage of 2011 numbers were analyzed. Linear regressions were used to determine trend significance. In the 10-year study period, 1,698 patients were identified with complete financial data. RESULTS: Overall total cost has increased significantly (P < .01). While revenues and CM for Medicare and Commercial patients remained steady between 2011 and 2021, CM for GMM patients decreased significantly (P = .01) to a low of 53.2% of the 2011 values. Since 2018, overall CM and revenues decreased significantly (P = .05, P = .01, respectively). CONCLUSION: While from 2011 to 2018 general revenues and CM were relatively steady, since 2018 they have decreased significantly to their lowest values in over a decade for GMM and commercial patients. This trend is concerning and may potentially lead to decreased access to care. Re-evaluation of reimbursement models for rTKA may be necessary to ensure the financial viability of this procedure and prevent issues with access to care. LEVEL OF EVIDENCE: III.

BACKGROUND: The impact of preoperative nasal colonization with methicillin resistant staphylococcus aureus (MRSA) on total joint arthroplasty (TJA) outcomes is not well understood. This study aimed to evaluate complications following TJA based on patients' preoperative staphylococcal colonization status. METHODS: We retrospectively analyzed all patients undergoing primary TJA between 2011 and 2022 who completed a preoperative nasal culture swab for staphylococcal colonization. Patients were 1:1:1 propensity matched using baseline characteristics, and stratified into 3 groups based on their colonization status: MRSA positive (MRSA+), methicillin sensitive staphylococcus aureus positive (MSSA+), and MSSA/MRSA negative (MSSA/MRSA-). All MRSA+ and MSSA + underwent decolonization with 5% povidone iodine, with the addition of intravenous vancomycin for MRSA + patients. Surgical outcomes were compared between groups. Of the 33,854 patients evaluated, 711 were included in final matched analysis (237 per group). RESULTS: The MRSA + TJA patients had longer hospital lengths of stay (P = .008), were less likely to discharge home (P = .003), and had higher 30-day (P = .030) and 90-day (P = .033) readmission rates compared to MSSA+ and MSSA/MRSA-patients, though 90-day major and minor complications were comparable across groups. MRSA + patients had higher rates of all-cause (P = .020), aseptic (P = .025) and septic revisions (P = .049) compared to the other cohorts. These findings held true for both total knee and total hip arthroplasty patients when analyzed separately. CONCLUSION: Despite targeted perioperative decolonization, MRSA + patients undergoing TJA have longer lengths of stay, higher readmission rates, and higher septic and aseptic revision rates. Surgeons should consider patients' preoperative MRSA colonization status when counseling on the risks of TJA.

BACKGROUND: Many studies have demonstrated that in patients whose primary language is not English, outcomes after an orthopaedic surgery are worse compared to primary English speakers. The goal of this study was to compare perioperative outcomes in patients undergoing total knee arthroplasty (TKA) who prefer English as their first language versus those who prefer a different language. METHODS: We retrospectively reviewed all patients who underwent primary TKA from May 2012 to July 2021. Patients were separated into two groups based on whether English was their preferred primary language (PPL). Of the 13,447 patients who underwent primary TKA, 11,290 reported English as their PPL, and 2,157 preferred a language other than English. Patients whose PPL was not English were further stratified based on whether they requested interpreter services. Multiple regression analyses were performed to determine the significance of perioperative outcomes while controlling for demographic differences. RESULTS: Our analysis found that non-English PPL patients had significantly lower rates of readmission (P = .040), overall revision (P = .028), and manipulation under anesthesia (MUA; P = .025) within 90 days postoperatively. Sub analyses of the non-English PPL group showed that those who requested interpreter services had significantly lower 1-year revision (P < .001) and overall MUA (P = .049) rates. CONCLUSION: Our results demonstrate that TKA patients who communicated in English without an interpreter were significantly more likely to undergo revision, readmission, and MUA. These findings may suggest that language barriers may make it more difficult to identify postoperative problems or concerns in non-English speakers, which may limit appropriate postoperative care.

BACKGROUND: Few studies have assessed how socioeconomic status (SES) influences patient-reported outcomes (PROMs) after total knee arthroplasty (TKA). This study evaluated the impact of patient median ZIP code income levels on PROMs after TKA. METHODS: We retrospectively reviewed patients at our institution undergoing primary, unilateral TKA from 2017 to 2020. Patients who did not have one-year postoperative PROMs were excluded. Patients were stratified based on the quartile of their home ZIP code median income from United States Census Bureau data. There were 1,267 patients included: 98 in quartile 1 (median income ≤ $46,308) (7.7%); 126 in quartile 2 (median income $46,309-$57,848) (10.0%); 194 in quartile 3 (median income $57,849-$74,011) (15.7%); and 849 in quartile 4 (median income ≥ $74,012) (66.4%). We collected baseline demographic data, 2-year outcomes, and PROMs preoperatively, as well as at 12 weeks and one year, postoperatively. RESULTS: The Knee Injury and Osteoarthritis Outcome Score for Joint Replacement was significantly higher in quartile 4 preoperatively (P < .001), 12 weeks postoperatively (P < .001), and one year postoperatively (P < .001). There were no significant differences in delta improvements of Knee Injury and Osteoarthritis Outcome Score for Joint Replacement from preoperative to 12 weeks or one year postoperatively. There were no significant differences in lengths of stay, discharge dispositions, readmissions, or revisions. CONCLUSION: Patients from lower income areas have slightly worse knee function preoperatively and worse outcomes following TKA. However, improvements in PROMs throughout the first year postoperatively are similar across income quartiles, suggesting that patients from lower income quartiles achieve comparable therapeutic benefits from TKA.

BACKGROUND: The Comprehensive Care for Joint Replacement requires patient-reported outcome measure (PROM) completion for total knee/hip arthroplasty (TKA/THA) patients. A 90% completion rate to avoid penalties was planned for 2023 but has been delayed. Our analysis compares TKA/THA PROM completion and results across demographics. We hypothesized that minority groups would be less likely to complete PROMs. METHODS: A retrospective review was performed from 2018 to 2021 of 16,119 patients who underwent primary elective TKA or THA at a single institution. Pairwise chi-squared tests, t-tests, analysis of variance, and multiple logistic regression analyses were used to compare PROM completion rates and scores across demographics and surgery type (TKA/THA). RESULTS: Comparing patients who had (N = 7,664) and did not have (N = 8,455) documented PROMs, completion rates were significantly lower in patients who were women, Black, Hispanic, less educated, used Medicaid insurance, lived in lower income neighborhoods, spoke non-English languages, required an interpreter, and underwent TKA versus THA. After regression analyses, odds ratios for PROM completion remained significantly lower in non-English speakers, Hispanic and Medicaid patients, lower income groups, and patients undergoing TKA. For the 31.8% of patients who completed both preoperative/postoperative PROMs, women, Black, and non-English speaking patients had significantly lower PROM scores for most measures preoperatively and postoperatively despite similar or better improvements after surgery. CONCLUSION: Patients undergoing TKA and non-English speaking, ethnic, and socioeconomic minorities are less likely to complete PROMs. Strategies to create, validate, and collect PROMs for these populations are needed to avoid exacerbation of healthcare disparities.

BACKGROUND: Revision total hip arthroplasty (rTHA) is a costly procedure, and its prevalence has been steadily increasing over time. This study aimed to examine trends in hospital cost, revenue, and contribution margin (CM) in patients undergoing rTHA. METHODS: We retrospectively reviewed all patients who underwent rTHA from June 2011 to May 2021 at our institution. Patients were stratified into groups based on insurance coverage: Medicare, government-managed Medicaid, or commercial insurance. Patient demographics, revenue (any payment the hospital received), direct cost (any cost associated with the surgery and hospitalization), total cost (the sum of direct and indirect costs), and CM (the difference between revenue and direct cost) were collected. Changes over time as a percentage of 2011 numbers were analyzed. Linear regression analyses were used to determine the overall trend's significance. Of the 1,613 patients identified, 661 were covered by Medicare, 449 by government-managed Medicaid, and 503 by commercial insurance plans. RESULTS: Medicare patients exhibited a significant upward trend in revenue (P < .001), total cost (P = .004), direct cost (P < .001), and an overall downward trend in CM (P = .037), with CM for these patients falling to 72.1% of 2011 values by 2021. CONCLUSION: In the Medicare population, reimbursement for rTHA has not matched increases in cost, leading to considerable reductions in CM. These trends affect the ability of hospitals to cover indirect costs, threatening access to care for patients who require this necessary procedure. Reimbursement models for rTHA should be reconsidered to ensure the financial feasibility of these procedures for all 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.

OBJECTIVE: To develop evidence-based consensus recommendations for the optimal timing of hip and knee arthroplasty to improve patient-important outcomes including, but not limited to, pain, function, infection, hospitalization, and death at 1 year for patients with symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis of the hip or knee who have previously attempted nonoperative therapy, and for whom nonoperative therapy was ineffective, and who have chosen to undergo elective hip or knee arthroplasty (collectively referred to as TJA). METHODS: We developed 13 clinically relevant population, intervention, comparator, outcomes (PICO) questions. After a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of evidence (high, moderate, low, or very low), and evidence tables were created. A Voting Panel, including 13 physicians and patients, discussed the PICO questions until consensus was achieved on the direction (for/against) and strength (strong/conditional) of the recommendations. RESULTS: The panel conditionally recommended against delaying TJA to pursue additional nonoperative treatment including physical therapy, nonsteroidal antiinflammatory drugs, ambulatory aids, and intraarticular injections. It conditionally recommended delaying TJA for nicotine reduction or cessation. The panel conditionally recommended delay for better glycemic control for patients who have diabetes mellitus, although no specific measure or level was identified. There was consensus that obesity by itself was not a reason for delay, but that weight loss should be strongly encouraged, and the increase in operative risk should be discussed. The panel conditionally recommended against delay in patients who have severe deformity or bone loss, or in patients who have a neuropathic joint. Evidence for all recommendations was graded as low or very low quality. CONCLUSION: This guideline provides evidence-based recommendations regarding the optimal timing of TJA in patients who have symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis for whom nonoperative therapy was ineffective to improve patient-important outcomes, including pain, function, infection, hospitalization, and death at 1 year. We acknowledge that the evidence is of low quality primarily due to indirectness and hope future research will allow for further refinement of the recommendations.
