Acuña AJ, Forlenza EM, Serino JM, Lavu MS, Della Valle CJ. Is Hospital-Based Outpatient Revision Total Knee Arthroplasty Safe? An Analysis of 2,171 Outpatient Aseptic Revision Procedures. J Arthroplasty 2024:S0883-5403(24)00619-3. [PMID: 38897263 DOI: 10.1016/j.arth.2024.06.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 06/09/2024] [Accepted: 06/10/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Outpatient primary total knee arthroplasty (TKA) has been well-established as a safe and effective procedure; however, the safety of outpatient revision TKA remains unclear. Therefore, this study utilized a large database to compare outcomes between outpatient and inpatient revision TKA. METHODS An all-payor database was queried to identify patients undergoing revision TKA from 2010 to 2022. Patients who had diagnosis codes related to periprosthetic joint infection (PJI) were excluded. Outpatient surgery was defined as a length of stay < 24 hours. Cohorts were matched by age, sex, Elixhauser Comorbidity Index, comorbidities (diabetes, obesity, tobacco use), components revised (1-versus 2-component), and revision etiology. Medical complications at 90 days and surgical complications at 1 and 2 years postoperatively were evaluated through multivariate logistic regression. A total of 4,342 aseptic revision TKAs were included. RESULTS No differences in patient characteristics, procedure type, or revision etiologies were seen between groups. The outpatient cohort had a lower risk of PJI (odds ratio (OR): 0.547, 95% confidence interval (CI): 0.337 to 0.869; P = .012), wound dehiscence (OR: 0.393, 95% CI: 0.225 to 0.658; P < .001), transfusion (OR: 0.241, 95% CI: 0.055 to 0.750; P = .027), reoperation (OR: 0.508, 95% CI: 0.305 to 0.822; P = .007), and any complication (OR: 0.696, 95% CI: 0.584 to 0.829; P < .001) at 90 days postoperatively. At 1 year and 2 years postoperatively, outpatient revision TKA patients had a lower incidence of revision for PJI (OR: 0.332, 95% CI: 0.131 to 0.743; P = .011 and OR: 0.446, 95% CI; 0.217 to 0.859; P = .020, respectively) and all-cause revision (OR: 0.518, 95% CI: 0.377 to 0.706; P < .001 and OR: 0.548, 95% CI: 0.422 to 0.712; P < .001, respectively). CONCLUSIONS Our findings suggest that revision TKA can be safely performed on an outpatient basis in appropriately selected patients who do not have an increased risk of adverse events relative to inpatient revision TKA. However, we could not ascertain case complexity in either cohort, and despite controlling for several potential confounders, other less tangible differences could exist between groups.

[PMID: 37972666 DOI: 10.1016/j.arth.2023.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 11/07/2023] [Accepted: 11/07/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND The rate of revision total joint arthroplasties is expected to increase drastically in the near future. Given the recent pandemic, there has been a general push toward early discharge. This study aimed to assess for predictors of early postoperative discharge after revision total knee arthroplasty (rTKA) and revision total hip arthroplasty (rTHA). METHODS There were 77 rTKA and 129 rTHA collected between January 1, 2019 and December 31, 2021. Demographic data, comorbidities, a comorbidity index, the modified frailty index (mFI-5), and surgical history were collected. The Common Procedural Terminology codes for each case were assessed. Patients were grouped into 2 cohorts, early discharge (length of stay [LOS] <24 hours) and late discharge (LOS >24 hours). RESULTS In the rTHA cohort, age >65 years, a history of cardiac or liver disease, an mFI-5 of >1, a comorbidity index of >2.7, a surgical time >122 minutes, and the need for a transfusion were predictors of prolonged LOS. Only the presence of a surgical time of >63 minutes or an mFI-5 >1 increased patient LOS in the rTKA cohort. In both rTHA and rTKA patients, periprosthetic joint infection resulted in a late discharge for all patients, mean 4.8 and 7.1 days, respectively. Dual component revision was performed in 70.5% of rTHA. Only 27.6% of rTKA were 2-component revisions or placements of an antibiotic spacer. CONCLUSIONS Several patient and surgical factors preclude early discharge candidacy. For rTHA, an mFI-5 of >2/5, comorbidity index of >4, or a surgical time of >122 minutes is predictive of prolonged LOS. For rTKA, an mFI-5 of >2/5, Charlson Comorbidity Index of >5, or a surgical time of >63 minutes predicts prolonged LOS.

Abstract
BACKGROUND This study examined the effect of prior pulmonary embolism (PE) on total joint arthroplasty (TJA) outcomes. METHODS We reviewed patients who had a prior PE undergoing TJA at a single tertiary medical center between January 1, 2012 and January 1, 2021. There were 177 TJA patients who had a prior PE who underwent 1:3 propensity-matching to patients without a history of prior PE. Bivariable and multivariable analyses were performed. Changes over time were evaluated. RESULTS Patients undergoing total knee arthroplasty who had a prior PE had more complications (25.3% versus 2.0%, P < .001), and postoperative PE (17.3% versus 0.0%, P < .001).and longer hospitalizations (3.15 versus 2.32 days, P = .006). Patients undergoing total hip arthroplasty who had a prior PE demonstrated more complications (14.7% versus 1.77%, P < .001) more postoperative PE (17.3% versus 0.0%, P < .001), and longer hospitalizations (3.30 versus 2.11 days, P < .001). Over the study, complication rates and hospitalizations lengths remained elevated in patients who had a prior PE. On multivariate analyses, prior PE was associated with longer hospitalizations (β: 0.67, P = .015) and increased complications (odds ratio [OR]: 9.44, P < .001) among total hip arthroplasty patients. Total knee arthroplasty patients had increased readmission (OR: 4.89, P = .003) and complication rates (OR: 21.4, P < .001). CONCLUSIONS Patients undergoing TJA who had a prior PE are at higher risk of requiring postoperative care. Therefore, thorough preoperative evaluation must be implemented, especially in clinical environments lacking resources for acute care escalation.

Abstract
BACKGROUND With the increasing utilization of total hip arthroplasty (THA) in patients who have a high comorbidity burden (HCB), coinciding with modifications to reimbursement models over the past decade, an evaluation of the financial impact of HCB on THA over time is warranted. This study aimed to investigate trends in revenue and cost associated with THA in HCB patients. METHODS Of 13,439 patients who had primary, elective THA between 2013 and 2021 at our institution, we retrospectively reviewed 978 patients considered to have HCB (Charlson comorbidity index ≥ 5 and American Society of Anesthesiology scores 3 or 4). We collected patient demographics, perioperative data, revenue, cost, and contribution margin (CM) of the inpatient episode. We analyzed changes as a percentage of 2013 values over time for these financial markers. Linear regression determined trend significance. The final analysis included 978 HCB patients who had complete financial data. RESULTS Between 2013 and 2021, direct costs increased significantly (P = .002), along with a nonsignificant increase in total costs (P = .056). While revenue remained steady during the study period (P = .486), the CM decreased markedly to 38.0% of 2013 values, although not statistically significant (P = .222). Rates of 90-day complications and home discharge remained steady throughout the study period. CONCLUSIONS Increasing costs for HCB patients undergoing THA were not matched by an equivalent increase in revenue, leading to dwindling CMs throughout the past decade. Re-evaluation of reimbursement models for THA that account for patients' HCB may be necessary to preserve broad access to care. LEVEL OF EVIDENCE III.

Oral Postoperative Antibiotic Prophylaxis for Outpatient Total Hip and Knee Arthroplasty: Describing Current Practices. J Arthroplasty 2024:S0883-5403(24)00336-X. [PMID: 38657914 DOI: 10.1016/j.arth.2024.04.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 04/07/2024] [Accepted: 04/08/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Despite an increase in outpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA), large-scale data are lacking on current practice for antibiotic prophylaxis prescribing. We aimed to describe current oral antibiotic prophylaxis practices nationally for outpatient THA and TKA. METHODS This nationwide retrospective cohort study included primary outpatient THA or TKA procedures in patients aged 18 to 64 years from 2018 to 2021 using a national claims database. Oral antibiotic prescriptions filled perioperatively (defined as 5 days before to 3 days after surgery) were extracted; these were categorized and assumed to represent postoperative prophylaxis. Multivariable logistic regression measured associations between patient and surgery characteristics and perioperative oral antibiotic prophylaxis. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) are reported. RESULTS Oral antibiotic prescriptions were filled in 16.5% of 73,015 outpatient THA and TKA (18.4% of 24,857 THAs, 15.5% of 48,158 TKAs) procedures. Prescriptions were most often for cephalosporins (74.3%), with cephalexin (52.8%), and cefadroxil (19.1%) being the most common. Non-cephalosporin antibiotics prescribed were mainly clindamycin (6.8%), sulfamethoxazole-trimethoprim (6.7%), and doxycycline (6.2%). The odds of receiving oral antibiotic prophylaxis were higher for THA compared to TKA (OR 1.13, 95% CI 1.09 to 1.18, P < .001) and in the presence of obesity, diabetes, and autoimmune conditions (OR 1.08 to 1.13, P < .001 to .01). Ambulatory surgery center procedures also had significantly increased odds of prophylaxis compared to hospital-based outpatient surgeries (OR 2.62, 95% CI 2.51 to 2.73, P < .001). Additionally, regional and time-based variations were noted. CONCLUSIONS Perioperative oral antibiotic prophylaxis prescriptions were filled in only 16.5% of outpatient THA and TKA cases, with variation in the type of antibiotic prescribed. The receipt of any prophylaxis and specific medications was associated with demographic, clinical, and procedure-related characteristics. Follow-up research will evaluate associations with infection risk reduction.

Abstract
BACKGROUND This study aimed to characterize changes in patient demographics and outcomes for same-day discharge total hip arthroplasty (THA) over a 10-year period at a single orthopaedic specialty hospital. METHODS A consecutive series of 1,654 patients between 2013 and 2022 who underwent unilateral THA and were discharged on the same calendar day were retrospectively reviewed. Patient demographics, including age, sex, body mass index (BMI), age-adjusted Charlson Comorbidity Index, and American Society of Anesthesiologists (ASA), were collected. Readmissions, complications, and unplanned visits were recorded for 90 days postoperatively. In order to compare the demographics of patients over time, patients were divided into 3 groups: Time Group A (2013 to 2016), Time Group B (2017 to 2019), and Time Group C (2020 to 2022). RESULTS The mean age, BMI, ASA score, and CCI increased significantly across each time group. Age increased from 57 years (range, 23 to 77) to 60 years (range, 20 to 87). The BMI increased from 28.1 (range, 18 to 41) to 29.4 (range, 18 to 47). The percentage of patients aged > 70 years almost doubled over time, as did the percentage of patients who had a BMI > 35. Overall complications increased from 3.44 to 6.82%, reflective of the changing health status of patients. Readmissions increased from 0.57 to 1.70% over time. Despite this, there were no readmissions for any patient within the first 24 hours of surgery. CONCLUSIONS Our study has 3 important findings. We identified a worsening patient demographic over time with an increasing percentage of patients of advanced age and higher BMI, ASA, and age-adjusted Charlson Comorbidity Index. Also, there was also an increase in readmissions, complications, and unplanned visits. In addition, despite this worsening patient demographic, there were no readmissions within 24 hours and a low rate of readmissions or unplanned visits within the first 48 hours across all time periods, suggesting that same-day discharge-THA continues to be safe in properly selected patients.

Abstract
BACKGROUND Same-day total hip arthroplasty (THA) and total knee arthroplasty (TKA) continue to gain popularity in the United States. The present study sought to quantify recent same-day outpatient trends taking into consideration the COVID-19 pandemic as well as the removal of these procedures from the Medicare inpatient only (IPO) list. METHODS Patients undergoing primary elective TKA and THA were identified using the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample from January 1, 2016, to December 31, 2020. The same-day cohort included Nationwide Ambulatory Surgery Sample and National Inpatient Sample patients with a length of stay = 0 days. The inpatient cohort included patients with length of stay ≥1 day. National estimates were extrapolated using weight functions. RESULTS From January 2016 to December 2020, the proportion of same-day TKA increased from 1.2 (719) to 62.4% (31,293) and the proportion of same-day THA increased from 2.0 (599) to 54.5% (18,252). Following removal from the Medicare IPO list, same-day TKAs increased from 3.2% (1,895) in December 2017 to 13.8% (9,269) in January 2018, and same-day THAs increased from 10.7% (4,295) in December 2019 to 22.5% (8,708) in January 2020. Between February and March 2020, same-day TKAs increased from 42.4 (26,148) to 44.4% (16,972) and same-day THAs increased from 28.5 (10,729) to 30.2% (7,409). CONCLUSIONS The proportion of same-day TKA and THA dramatically increased following removal from the Medicare IPO list and in response to the COVID-19 pandemic. By December 2020, same-day TKA and THA accounted for >50% of all cases performed in the United States.

Risk Factors for Return to the Emergency Department and Readmission After Same-Day Discharge Total Joint Arthroplasty. J Arthroplasty 2024:S0883-5403(24)00194-3. [PMID: 38458335 DOI: 10.1016/j.arth.2024.02.074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 02/21/2024] [Accepted: 02/22/2024] [Indexed: 03/10/2024] Open
Abstract
INTRODUCTION Same day discharge (SDD) after total joint arthroplasty (TJA) is safe and cost effective. However, benefits may be offset by the potential cost of emergency department (ED) visits and readmissions. We identified risk factors for return to the ED and readmission in patients who underwent SDD and inpatient (IP) stays after TJA. METHODS We performed a retrospective review of patients who underwent primary TJA at an academic institution over the course of one year. There were 1,708 consecutive TJAs (721 THA [total hip arthroplasty] and 987 TKA [total knee arthroplasty]) included. A SDD occurred after 1,199 (70%) TJAs, 523 THAs, and 676 TKAs. We compared the demographics and comorbidities of patients who have SDD or IP who stayed following TJA. We documented rates of return to the ED or readmission within 90 days of surgery. Cohorts were compared using the Student's t-test or Chi-squared test. Significant findings were those with P-value <0.05. RESULTS The SDD cohort had a significantly higher rate of young, non-White men who had a lower body mass index (BMI) and fewer comorbidities than the IP cohort. Rates of return to ED and readmission were similar between SDD and IP cohorts after TJA and similar between THA and TKA. Factors that significantly influenced return to ED included a higher American Society of Anaesthesiologists (ASA) score (SDD, IP), a higher Charlson Comorbidity Index (CCI) score (SDD, IP), a lower BMI (IP), and a psychological diagnosis (SDD, IP). Factors that significantly influenced readmission rates included a higher ASA score (SDD), older age (SDD), and psychological diagnosis (SDD, IP). CONCLUSION Patients who discharge the same day after primary TJA have similar rates of return to the ED and readmission as those admitted as an inpatient. Patients who had a psychological diagnosis, and particularly a diagnosis of depression, are at higher risk for return to the ED and readmission after primary TJA, regardless of discharge the same-day or inpatient admission. Improved measures that attempt to further treat and optimize this patient population could reduce unnecessary postoperative ED visits.

Camillieri S. Does Participation in Virtual or In-Person Preoperative Education Relate to Reduced Length of Stay After Total Joint Arthroplasty? HSS J 2024; 20:83-89. [PMID: 38356753 PMCID: PMC10863587 DOI: 10.1177/15563316231208454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 06/02/2023] [Indexed: 02/16/2024]
Abstract
Background Advancements in surgical procedures for total joint arthroplasty (TJA) have resulted in more effective procedures with more rapid recovery. To prepare patients for surgery, many organizations offer a preoperative "joint class," which has been associated with reduced length of stay (LOS). Virtual modes of education are increasingly favored for those having TJA. Purpose To determine whether participation in an individually administered preoperative educational session ("Prehab") relates to reduced LOS or increased likelihood of same-day discharge (SDD) for those undergoing TJA. Additionally, to establish whether and the virtual mode of education provision is superior or inferior to the in-person mode with regards to LOS benefits. Methods The author conducted a case-control study of 2532 patients who had a primary or revision TJA between January 2022 and August 2022 at a single institution. Data were obtained from the electronic medical record. A total of 1118 patients attended Prehab; 1414 patients did not. Patients were included if they were over the age of 18 and had a total hip arthroplasty (THA) or total knee arthroplasty (TKA) during the study period. T-tests, chi-square χ2 tests, and binomial logistic regression were used to evaluate the LOS and SDD outcomes for those who participated in Prehab compared with those who did not. Results Those receiving Prehab in any form had shorter LOS than those who had not. Those receiving virtual Prehab had the shortest LOS. There was no difference in the rate of SDD for outpatient-class patients. Conclusion Preoperative education is associated with LOS benefits to patients undergoing TJA. The virtual mode of education provision is at minimum non-inferior, and may be superior, to the in-person mode. The lack of statistically significant between-group differences for SDD outcomes may be explained by a lack of SDD-specific educational content provided during Prehab.

Increasing the Volume of Outpatient Total Joint Arthroplasty Procedures: An Evaluation of a Novel Rapid Recovery Pathway Program Within an Academic Medical Center. HSS J 2024; 20:35-40. [PMID: 38356745 PMCID: PMC10863602 DOI: 10.1177/15563316231211335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 10/10/2023] [Indexed: 02/16/2024]
Abstract
Background There has been a national trend toward shifting joint arthroplasty procedures to the outpatient setting. These cases are often performed in freestanding ambulatory surgery centers (ASCs), which are often not accessible to surgeons within academic practices. Purposes We sought to investigate a novel rapid recovery program used to transition arthroplasty patients to an outpatient-based care system within an academic medical center. Methods All patients undergoing hip or knee arthroplasty between November 2019 and April 2021 were retrospectively evaluated for their eligibility for a rapid recovery pathway through the Extended Stay Unit (ESU) based on clinical and social criteria. Once admitted, patients were evaluated for whether they were discharged from the unit or if hospital admission was necessary. Results Out of the 444 patients deemed candidates for the rapid recovery program, 188 patients were admitted to the ESU (42.3%); 18 (9.6%) required inpatient hospital admission, with the majority of these due to failing physical therapy (16; 88.9%). Of the ESU patients who were successfully discharged home, 55 (32.4%) were discharged on postoperative day (POD) 0 and 115 (67.6%) on POD 1 (<23 hours). Conclusion As total joint arthroplasties shift toward the outpatient setting, surgeons in academic institutions must employ strategies to increase their volume of patient candidates for outpatient procedures. Our retrospective study of prospectively collected data suggests the feasibility of creating a separate rapid recovery unit within the hospital that can be an effective method by which to eventually transition to the ASC setting.

Abstract
Studies regarding the safety of same day discharge (SDD) in patients ≥65 years of age undergoing total hip arthroplasty (THA) are lacking. A retrospective review of 69 patients undergoing SDD following primary THA in 2 free-standing ambulatory surgical centers (ASCs) was performed to evaluate for safety and complications. Sixty-six patients met SDD goals, while 1 patient required transport to a hospital for transfusion, and 2 patients underwent overnight observation in the ASC. This study reveals that with appropriate preoperative evaluation, patient selection, and education, THA in a free-standing ASC can be safely performed in patients ≥65 years of age.

Abstract
This is a retrospective study. As new surgical techniques and improved perioperative care approaches have become available, the same-day discharge in selected total knee arthroplasty (TKA) patients was introduced to decrease health care costs without compromising outcomes. This study aimed to compare clinical and functional outcomes between same-day discharge TKA patients and inpatient-discharge TKA patients. A retrospective review of 100 consecutive patients with same-day discharge matched to a cohort of 300 patients with inpatient discharge that underwent TKA by a single surgeon at a tertiary referral center was conducted. Propensity-score matching was performed to adjust for baseline differences in preoperative patient demographics, medical comorbidities, and patient-reported outcome measures (PROMs) between both cohorts. All patients had a minimum of 1-year follow-up (range: 1.2-2.8 years). In terms of clinical outcomes for the propensity score-matched cohorts, there was no significant difference in terms of revision rates (1.0 vs. 1.3%, p = 0.76), 90-day emergency department visits (3.0 vs. 3.3%, p = 0.35), 30-day readmission rates (1.0 vs. 1.3%, p = 0.45), and 90-day readmission rates (3.0 vs. 3.6%, p = 0.69). Patients with same-day discharge demonstrated significantly higher postoperative PROM scores, at both 3-month and 1-year follow-up, for PROMIS-10 Physical Score (50 vs. 46, p = 0.028), PROMIS-10 Mental Score (56 vs. 53, p = 0.039), and Physical SF10A (57 vs. 52, p = 0.013). This study showed that patients with same-day discharge had similar clinical outcomes and superior functional outcomes, when compared with patients that had a standard inpatient protocol. This suggests that same-day discharge following TKA may be a safe, viable option in selected total knee joint arthroplasty patients.

Abstract
Background A recent meta-analysis comparing inpatient and outpatient total shoulder arthroplasty (TSA) showed no statistically significant differences in complications, readmissions, revisions, and infections. However, there remains no research on the appropriate patient selection for outpatient TSA surgeries. This retrospective review seeks to aid surgeons in refining a safe patient selection algorithm by evaluating risk factors through a large database analysis of TSA surgeries. Methods Patients who underwent TSA between 2015 and 2020 were identified in the National Surgical Quality Improvement Program database. Patients with a hospital stay of 0 days were designated as outpatient procedures. Multivariate analyses were used to determine risk factors for 30-day readmission following outpatient TSA and whether risk factors remained significant following overnight hospital stay. Results A total of 2431 outpatient TSA patients were identified. The incidence of 30-day readmission was 1.8%. The majority of readmissions were due to pulmonary complications. The clinically significant risk factors for 30-day readmission were chronic steroid use (odds ratio [OR] 3.55, 95% confidence interval [CI] 1.34-9.43; P = .011), chronic obstructive pulmonary disease (COPD) (OR 3.11, 95% CI 1.16-8.34; P = .024), and current smoking status (OR 2.27, 95% CI 1.02-5.03; P = .045). After overnight hospital stay, chronic steroid use and current smoking status were not significant, but COPD remained significant. Conclusion Patients with chronic steroid use, COPD, or current smoking status are at increased risk for 30-day readmission. Inpatient hospital stay appears to benefit patients with chronic steroid use and current smoking status. Patients with COPD should be admitted for inpatient stay postoperatively but may still have high 30-day readmission rates following discharge.

Abstract
BACKGROUND Literature suggests that outpatient arthroplasty may result in low rates of complications and readmissions. There is, however, a dearth of information on the relative safety of total knee arthroplasty (TKA) performed at stand-alone ambulatory surgery centers (ASCs) versus hospital outpatient (HOP) settings. We aimed to compare safety profiles and 90-day adverse events of these 2 cohorts. METHODS Prospectively collected data were reviewed on all patients who underwent outpatient TKA from 2015 to 2022. The ASC and HOP groups were compared, and differences in demographics, complications, reoperations, revisions, readmissions, and emergency department (ED) visits within 90 days of surgery were analyzed. There were 4 surgeons who performed 4,307 TKAs during the study period, including 740 outpatient cases (ASC = 157; HOP = 583). The ASC patients were younger than HOP patients (ASC = 61 versus HOP = 65; P < .001). Body mass index and sex did not differ significantly between groups. RESULTS Within 90 days, 44 (6%) complications occurred. No differences were observed between groups in rates of 90-day complications (ASC = 9 of 157, 5.7% versus HOP = 35 of 583, 6.0%; P = .899), reoperations (ASC = 2 of 157, 1.3% versus HOP = 3 of 583, 0.5%; P = .303), revisions (ASC = 0 of 157 versus HOP = 3 of 583, 0.5%; P = 1), readmissions (ASC = 3 of 157, 1.9% versus HOP = 8 of 583, 1.4%; P = .625), and ED visits (ASC = 1 of 157, 0.6% versus HOP = 3 of 583, 0.5%; P = .853). CONCLUSION These results suggest that in appropriately selected patients, outpatient TKA can be safely performed in both ASC and HOP settings with similar low rates of 90-day complications, reoperations, revisions, readmissions, and ED visits.

Association between same-day discharge shoulder arthroplasty and risk of adverse events in patients with American Society of Anesthesiologists classification ≥3: a cohort study.

Abstract
BACKGROUND Same-day discharge for shoulder arthroplasty (SA) is well-supported in the literature; however, most studies have focused on healthier patients. Indications for same-day discharge SA have expanded to include patients with more comorbidities, but safety of same-day discharge in this population remains unknown. We sought to compare outcomes following same-day discharge vs. inpatient SA in a cohort of patients considered higher risk for adverse events, defined as an American Society of Anesthesiologists (ASA) classification of ≥3. METHODS Data from Kaiser Permanente's SA registry were utilized to conduct a retrospective cohort study. All patients with an ASA classification of ≥3 who underwent primary elective anatomic or reverse SA in a hospital from 2018 to 2020 were included. The exposure of interest was in-hospital length of stay: same-day discharge vs. ≥1-night hospital inpatient stay. The likelihood of 90-day post-discharge events, including emergency department (ED) visit, readmission, cardiac complication, venous thromboembolism, and mortality, was evaluated using propensity score-weighted logistic regression with noninferiority testing using a margin of 1.10. RESULTS The cohort included a total of 1814 SA patients, of whom 1005 (55.4%) had same-day discharge. In propensity score-weighted models, same-day discharge was not inferior to an inpatient stay SA regarding 90-day readmission (odds ratio [OR] = 0.64, one-sided 95% upper bound [UB] = 0.89) and overall complications (OR = 0.67, 95% UB = 1.00). We lacked evidence in support of noninferiority for 90-day ED visit (OR = 0.96, 95% UB = 1.18), cardiac event (OR = 0.68, 95% UB = 1.11), or venous thromboembolism (OR = 0.91, 95% UB = 2.15). Infections, revisions for instability, and mortality were too rare to evaluate using regression analysis. CONCLUSIONS In a cohort of over 1800 patients with an ASA of ≥3, we found same-day discharge SA did not increase the likelihood of ED visits, readmissions, or complications compared with an inpatient stay, and same-day discharge was not inferior to an inpatient stay with regard to readmissions and overall complications. These findings suggest that it is possible to expand indications for same-day discharge SA in the hospital setting.

Abstract
BACKGROUND The objective of this study was to assess racial and ethnic disparities in short-stay (< 2-midnight length of stay) and outpatient (same-day discharge) total joint arthroplasties (TJAs). We aimed to determine (1) whether there are differences in postoperative outcomes between short-stay Black, Hispanic, and White patients and (2) the trend in utilization rates of short-stay and outpatient TJA across these racial groups. METHODS This was a retrospective cohort study of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Short-stay TJAs done between 2008 and 2020 were identified. Patient demographics, comorbidities, and 30-day postoperative outcomes were assessed. Multivariate regression analysis was used to assess differences between racial groups in minor and major complication rates, as well as readmission and revision surgery rates. RESULTS Of a total of 191,315 patients, 88% were White, 8.3% were Black, and 3.9% were Hispanic. Minority patients were younger and had greater comorbidity burden when compared with Whites. Black patients had greater rates of transfusions and wound dehiscence when compared with White and Hispanic patients ( P < 0.001, P = 0.019, respectively). Black patients had lower adjusted odds of minor complications (odds ratio [OR], 0.87; confidence interval [CI], 0.78 to 0.98), and minorities had lower revision surgery rates in comparison with Whites (OR, 0.70; CI, 0.53 to 0.92, and OR, 0.84; CI, 0.71 to 0.99, respectively). The utilization rate for short-stay TJA was most pronounced for Whites. CONCLUSION There continues to persist marked racial disparities in demographic characteristics and comorbidity burden in minority patients undergoing short-stay and outpatient TJA procedures. As outpatient-based TJA becomes more routine, opportunities to address these racial disparities will become increasingly more important to optimize social determinants of health.

Abstract
BACKGROUND The rates of blood transfusion following primary and revision total hip arthroplasty (THA) remain as high as 9% and 18%, respectively, contributing to patient morbidity and healthcare costs. Existing predictive tools are limited to specific populations, thereby diminishing their clinical applicability. This study aimed to externally validate our previous institutionally developed machine learning (ML) algorithms to predict the risk of postoperative blood transfusion following primary and revision THA using national inpatient data. METHODS Five ML algorithms were trained and validated using data from 101,266 primary THA and 8,594 revision THA patients from a large national database to predict postoperative transfusion risk after primary and revision THA. Models were assessed and compared based on discrimination, calibration, and decision curve analysis. RESULTS The most important predictors of transfusion following primary and revision THA were preoperative hematocrit (<39.4%) and operation time (>157 minutes), respectively. All ML models demonstrated excellent discrimination (area under the curve (AUC) >0.8) in primary and revision THA patients, with artificial neural network (AUC = 0.84, slope = 1.11, intercept = -0.04, Brier score = 0.04), and elastic-net-penalized logistic regression (AUC = 0.85, slope = 1.08, intercept = -0.01, and Brier score = 0.12) performing best, respectively. On decision curve analysis, all 5 models demonstrated a higher net benefit than the conventional strategy of intervening for all or no patients in both patient cohorts. CONCLUSIONS This study successfully validated our previous institutionally developed ML algorithms for the prediction of blood transfusion following primary and revision THA. Our findings highlight the potential generalizability of predictive ML tools developed using nationally representative data in THA patients.

Abstract
INTRODUCTION As ne arly half of all total joint arthroplasty (TJA) procedures are projected to be performed in the outpatient setting by 2026, the impact of this trend on health disparities remains to be explored. This study investigated the racial/ethnic differences in the proportion of TJA performed as outpatient as well as the impact of outpatient surgery on 30-day complication and readmission rates. METHODS The ACS National Surgical Quality Improvement Program was retrospectively reviewed for all patients who underwent primary, elective total hip and knee arthroplasty (THA, TKA) between 2011 and 2018. The proportion of TJA performed as an outpatient, 30-day complications, and 30-day readmission among African American, Hispanic, Asian, Native American/Alaskan, and Hawaiian/Pacific Islander patients were each compared to White patients (control group). Analyses were performed for each racial/ethnic group separately. A general linear model (GLM) was used to calculate the odds ratios for receiving TJA in an outpatient vs. inpatient setting while adjusting for age, gender, body mass index (BMI), functional status, and comorbidities. RESULTS In total, 170,722 THAs and 285,920 TKAs were analyzed. Compared to White patients, non-White patients had higher likelihood of THA or TKA performed as an outpatient (OR 1.31 and 1.24 respectively for African American patients, OR 1.65 and 1.76 respectively for Hispanic patients, and OR 1.66 and 1.59 respectively for Asian patients, p < 0.001). Outpatient surgery did not lead to increased complications in any of the study groups compared to inpatient surgery (p > 0.05). However, readmission rates were significantly higher for outpatient TKA in all the study groups compared to inpatient TKA (OR range 2.47-10.15, p < 0.001). Complication and readmission rates were similar between inpatient and outpatient THA for all the study groups. CONCLUSION While this study demonstrated higher proportion of TJA performed as an outpatient among most non-White racial/ethnic groups, this observation should be tempered with the increased readmission rates observed in outpatient TKA, which could further the disparities gap in health outcomes.

Abstract
Total joint arthroplasty is one of the most commonly performed surgical procedures in the United States, and projected numbers are expected to double in the next ten years. From 2018 to 2020, total hip and knee arthroplasty were removed from the United States' Center for Medicare and Medicaid Services "inpatient-only" list, accelerating this migration to the ambulatory setting. Appropriate patient selection, including age, body mass index, comorbidities, and adequate social support, is critical for successful ambulatory total joint arthroplasty. General anesthesia and neuraxial anesthesia are both safe and effective anesthetic choices, and recent studies in this population have found no difference in outcomes. Multimodal analgesia, including acetaminophen, nonsteroidal anti-inflammatory drugs, local infiltration analgesia, and peripheral nerve blocks, is the foundation for adequate pain control. Common reasons for "failure to launch" include postoperative urinary retention, postoperative nausea and vomiting, inadequate analgesia, and hypotension.

Abstract
BACKGROUND The number of total knee arthroplasties (TKAs) performed on an outpatient basis continues to increase. The purpose of this study was to compare complication rates over the last decade to evaluate trends in the safety of outpatient TKA. METHODS Patients who underwent TKA from 2010 to 2020 from a large administrative claims database were retrospectively identified and stratified based on the year of surgery. Propensity-score matching was performed to match patients who were discharged within 24 hours of surgery to inpatients based on age, sex, comorbidity index, and year of surgery. Linear regression analyses were used to compare trends from 2010 to 2020. The 90-day adverse events in the early cohort (2010-2012) were compared to those in the late cohort (2018-2020) using multivariable regression analyses. Of the 547,137 patients in the sample, 28,951 outpatients (5.3%) were propensity matched to inpatients. RESULTS The incidence of outpatient TKA increased from 2010 to 2018 (1.9 versus 13.8%, P < .001). Despite a similar complication rate early (24.1 versus 22.6%, P = .164), outpatient TKA had fewer complications at the end of the study period (13.7 versus 16.7%, P < .001). Multivariate analyses demonstrated that the risk of any complication after outpatient TKA was lower than inpatient from 2018 to 2020 (odds ratio, 0.78; 95% confidence interval, 0.71-0.84). CONCLUSIONS Complications in both cohorts declined dramatically suggesting improvements in quality of care over time, with the greatest decline in patients undergoing outpatient surgery. These results suggest that outpatient TKA today is not higher risk for the patient than inpatient TKA. LEVEL OF EVIDENCE Level III.

Effects of Dexamethasone on Postoperative Glycemic Control in Diabetic Patients Following Primary Total Joint Arthroplasty: A Retrospective Cohort Study. J Arthroplasty 2023:S0883-5403(23)00348-0. [PMID: 37040822 DOI: 10.1016/j.arth.2023.04.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 03/24/2023] [Accepted: 04/03/2023] [Indexed: 04/13/2023] Open
Abstract
INTRODUCTION Concerns regarding the effects of dexamethasone on diabetics' glucose control have stymied its use following total joint arthroplasty (TJA). This study aimed to evaluate the effects of two intravenous (IV) perioperative doses of dexamethasone on glucose levels, pain scores, and inpatient opioid consumption following TJA in diabetic patients. METHODS A retrospective review of 523 diabetic patients who underwent primary elective THA and 953 diabetic patients who underwent primary elective TKA between May 6, 2020 and December 17, 2021. Patients who received one dose (1D) of perioperative dexamethasone 10 mg IV were compared to patients who received two doses (2D). Primary outcomes included postoperative glucose levels, opioid consumption as morphine milligram equivalences (MMEs), postoperative pain as Verbal Rating Scale (VRS) pain scores, and postoperative complications. RESULTS The 2D TKA cohort had significantly greater average and maximum blood glucose levels from 24 to 60 hours compared to the 1D TKA cohort. The 2D THA cohort had significantly greater average blood glucose levels at 24 to 36 hours compared to the 1D THA cohort. However, the 2D TKA group had significantly reduced opioid consumption from 24 to 72 hours and reduced total consumption compared to the 1D TKA group. VRS pain scores did not differ between cohorts for both TKA and THA at any interval. CONCLUSION Administration of a second perioperative dose of dexamethasone was associated with increased postoperative blood glucose levels. However, the observed effect on glucose control may not outweigh the clinical benefits of a second perioperative dose of glucocorticoids.

Abstract
BACKGROUND Trends over the past decade suggest a steady increase in the proportion of total knee arthroplasty (TKA) performed on an outpatient basis. However, the optimal patient selection criteria for outpatient TKA remain unclear. We aimed to describe longitudinal trends in patients selected for outpatient TKA and identify risk factors for 30-day morbidity following inpatient and outpatient TKA. METHODS We identified 379,959 primary TKA patients, 17,170 (4.5%) of whom underwent outpatient surgery from 2012 to 2020 within a large national database. We used regression models to evaluate trends in outpatient TKA, factors associated with undergoing outpatient (vs. inpatient) TKA and 30-day morbidity following outpatient and inpatient TKA. We used Receiver Operating Curves (ROC) to examine cut-off points for continuous risk factors. RESULTS The proportion of patients undergoing outpatient TKA increased from 0.4% in 2012 to 14.1% in 2020. Younger age, male sex, lower body mass index (BMI), higher hematocrit, and fewer comorbidities were associated with receiving outpatient (vs. inpatient) TKA. Variables associated with 30-day morbidity in the outpatient group included older age, chronic dyspnea, chronic obstructive pulmonary disease (COPD), and higher BMI. ROC curves indicated outpatients aged 68 and older, or with a BMI of 31.4 or higher were more likely to experience 30-day complications. CONCLUSION The proportion of patients undergoing outpatient TKA has been increasing since 2012. Older age (≥68 years), a higher BMI (≥31.4), and comorbidities such as chronic dyspnea, COPD, diabetes, and hypertension were associated with an increased odds of 30-day morbidity following outpatient TKA.

Abstract
BACKGROUND Despite advancements in total hip arthroplasty (THA) and the increased utilization of tranexamic acid, acute blood loss anemia necessitating allogeneic blood transfusion persists as a post-operative complication. The prevalence of allogeneic blood transfusion in primary THA has been reported to be as high as 9%. Therefore, this study aimed to develop and validate novel machine learning models for the prediction of transfusion rates following primary total hip arthroplasty. METHODS A total of 7265 consecutive patients who underwent primary total hip arthroplasty were evaluated using a single tertiary referral institution database. Patient charts were manually reviewed to identify patient demographics and surgical variables that may be associated with transfusion rates. Four state-of-the-art machine learning algorithms were developed to predict transfusion rates following primary THA, and these models were assessed by discrimination, calibration, and decision curve analysis. RESULTS The factors most significantly associated with transfusion rates include tranexamic acid usage, bleeding disorders, and pre-operative hematocrit (< 33%). The four machine learning models all achieved excellent performance across discrimination (AUC > 0.78), calibration, and decision curve analysis. CONCLUSION This study developed machine learning models for the prediction of patient-specific transfusion rates following primary total hip arthroplasty. The results represent a novel application of machine learning, and has the potential to improve outcomes and pre-operative planning. LEVEL OF EVIDENCE III, case-control retrospective analysis.

Abstract
IMPORTANCE Health care mergers and acquisitions have increased vertical integration of skilled nursing facilities (SNFs) in health care networks. While vertical integration may result in improved care coordination and quality, it may also lead to excess utilization, as SNFs are paid a per diem rate. OBJECTIVE To determine the association of vertical integration of SNFs within hospital networks with SNF utilization, readmissions, and spending for Medicare beneficiaries undergoing elective hip replacement. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study evaluated 100% Medicare administrative claims for nonfederal acute care hospitals performing at least 10 elective hip replacements during the study period. Fee-for-service Medicare beneficiaries aged 66 to 99 years who underwent elective hip replacement between January 1, 2016, and December 31, 2017, with continuous Medicare coverage for 3 months before and 6 months after surgery were included. Data were analyzed from February 2 to August 8, 2022. EXPOSURES Treatment at a hospital within a network that also owns at least 1 SNF based on the 2017 American Hospital Association survey. MAIN OUTCOMES AND MEASURES Rates of SNF utilization, 30-day readmissions, and price-standardized 30-day episode payments. Hierarchical multivariable logistic and linear regression clustered at hospitals was performed with adjusting for patient, hospital, and network characteristics. RESULTS A total of 150 788 patients (61.4% women; mean [SD] age, 74.3 [6.4] years) underwent hip replacement. After risk adjustment, vertical SNF integration was associated with a higher rate of SNF utilization (21.7% [95% CI, 20.4%-23.0%] vs 19.7% [95% CI, 18.7%-20.7%]; adjusted odds ratio [aOR], 1.15 [95% CI, 1.03-1.29]; P = .01) and lower 30-day readmission rate (5.6% [95% CI, 5.4%-5.8%] vs 5.9% [95% CI, 5.7%-6.1%]; aOR, 0.94 [95% CI, 0.89-0.99]; P = .03). Despite higher SNF utilization, the total adjusted 30-day episode payments were slightly lower ($20 230 [95% CI, $20 035-$20 425] vs $20 487 [95% CI, $20 314-$20 660]; difference, -$275 [95% CI, -$15 to -$498]; P = .04) driven by lower postacute payments and shorter SNF length of stays. Adjusted readmission rates were particularly low for patients not sent to an SNF (3.6% [95% CI, 3.4%-3.7%]; P < .001) but were significantly higher for patients with an SNF length of stay less than 5 days (41.3% [95% CI, 39.2%-43.3%]; P < .001). CONCLUSIONS AND RELEVANCE In this cross-sectional study of Medicare beneficiaries undergoing elective hip replacements, vertical integration of SNFs in a hospital network was associated with higher rates of SNF utilization and lower rates of readmissions without evidence of higher overall episode payments. These findings support the purported value of integrating SNFs into hospital networks but also suggest that there is room for improving the postoperative care of patients in SNFs early in their stay.

Abstract
BACKGROUND Musculoskeletal care teams can benefit from simple, standardized, and reliable preoperative tools for assessing discharge disposition after total joint arthroplasty. Our objective was to compare the predictive strength of the Ascension Seton Lower Extremity Inpatient-Outpatient (LET-IN-OUT) tool versus the American Society of Anesthesiologists Physical Status (ASA-PS) score for predicting early postoperative discharge. METHODS We retrospectively extracted sociodemographic, surgical admission, postoperative day (POD) of discharge, 90-day readmissions, and predictions of the LET-IN-OUT and ASA-PS tools from the electronic records of 563 consecutive hip or knee arthroplasty patients (mean age 65 [SD 9.6], 54% women). Included patients who underwent a total hip arthroplasty (THA) or total knee arthroplasty (TKA) at a single health system between June 2020 and March 2021. We performed descriptive statistics and analyzed predictive values of each tool, defining "early discharge" primarily as discharge before the second postoperative day (POD 2), and secondarily as before 24 hours, and on the same calendar day (POD 0) as surgery. RESULTS The LET-IN-OUT tool demonstrated superior predictive power among hip and knee arthroplasty patients compared to the ASA-PS tool for discharge prior to POD 2 (positive predictive value [PPV] 89 versus 83%, positive likelihood ratio [+LR] 2.0 versus 1.2), discharge before 24 hours (PPV 86 versus 70%, +LR 2.9 versus 1.2), and discharge on POD 0 (PPV 34% versus 30%, +LR 1.2 versus 1.1). CONCLUSIONS The Ascension Seton Lower Extremity Inpatient-Outpatient tool predicted patients suitable for early discharge following THA or TKA and did so more effectively than the ASA-PS score.

Abstract
BACKGROUND Different approaches for total hip arthroplasty (THA) may offer advantages in regard to achieving same-day-discharge (SDD) success. METHODS We retrospectively identified patients aged ≥ 18 years who underwent elective primary THA from 2015 to 2020 who were formally enrolled in a single institution's SDD program. A total of 1,127 and 207 patients underwent THA via direct anterior approach and posterior approach, respectively, were included. Cohorts were assigned based on approach. The primary outcome was failure-to-launch, defined as hospital stay extending past 1 midnight. Secondary outcomes included Forgotten Joint Score-12, Hip Disability and Osteoarthritis Outcome Score for Joint Replacement, 90-day readmission and revision rate, and surgical time. Patient-reported outcomes were collected at 3 and 12 months. RESULTS After controlling for demographic differences, posterior approach patients had higher rates of failure-to-launch (12.1% versus 5.9%, P = .002) and longer surgical times (99 versus 80 minutes; P < .001) compared to direct anterior approach patients. The cohorts had similar readmission (1.7% versus 1.4%; P = .64) and revision rates (1% versus 1%; P = .88). The magnitude of improvement in Hip Disability and Osteoarthritis Outcome Score for Joint Replacement scores from preoperative to 12 months was similar between cohorts (35.3 versus 34.5; P = .42). The differences in outcome scores between cohorts at each time point were not considered clinically significant. CONCLUSION Our analysis suggests that patient selection and surgical approach may be important for achieving SDD. Surgical approach did not significantly impact readmission or revision rates nor did it have a meaningful impact on patient-reported outcomes in the first year after surgery.

Abstract
BACKGROUND Outpatient total joint arthroplasty (TJA) has been shown to be both safe and cost-effective in appropriately selected patients and continues to expand substantially across the United States. Using online crowdsourcing, we aimed to assess population perceptions regarding outpatient TJA and to determine factors associated with preference for outpatient versus inpatient arthroplasty. METHODS A closed-ended survey consisting of 39 questions was administered to members of a public platform. Study participants responded to questions regarding demographic factors and outpatient TJA. Validated assessments to capture health literacy and engagement were also used. To determine factors associated with preference for outpatient TJA, multivariable logistic regression analyses were performed. RESULTS In total, 900 participants completed the survey. After exclusion of surveys with incomplete data, 725 responses remained for analysis (80.6%). Over half (59.9%) of the survey participants would feel comfortable going home the same day of surgery following TJA. However, two-thirds (64.6%) would prefer to stay in the hospital following TJA. The majority (68.0%) of respondents perceive a hospital setting as the safest location for TJA. The 3 major concerns regarding outpatient TJA were cost, post-operative pain control, and post-operative complication. Among the 111 respondents (15.3%) who would prefer outpatient TJA, 45% would pay more out-of-pocket, 63.1% travel further, and 55.9% would be willing to wait longer to have their surgery performed as an outpatient. On multivariable regressions, those living in a suburban setting (adjusted odds ratios, 95% confidence intervals: 4.2 [1.3-2.7], P = .02) and >60 year old adjusted odds ratios (95% confidence intervals: 8 [2-33.1], P = .004) were more likely to prefer outpatient TJA. CONCLUSION Despite the rise in outpatient TJA, the majority of the public appears to prefer inpatient TJA and the minority would expect to be discharged home the same day. Our data can be used to address specific patient concerns regarding outpatient TJA and set realistic expectations for hospital systems and ambulatory facilities.

Abstract
PURPOSE OF REVIEW With an expected rise in day care procedures with enhanced recovery programs, the use of specific regional anaesthesia can be useful. In this review, we will provide insight in the used regional block and medication so far known and its applicability in a day care setting. RECENT FINDINGS Regional anaesthesia has been improved with the aid of ultrasound-guided placement. However, it is not commonly used in the outpatient setting. Old, short acting local anaesthetics have found a second life and may be especially beneficial in the ambulatory setting replacing more long-acting local anaesthetics such as bupivacaine.To improve efficiency, a dedicated block room may facilitate the performance of regional anaesthesia. However, cost-efficacy for improved operating time, patient care and hospital efficiency has to be established. SUMMARY Regional anaesthesia has proven to be beneficial in ambulatory setting. Several short acting local anaesthetics are favourable over bupivacaine in the day care surgery. And if available, there are reports of the benefit of an additional block room used in a parallel (monitored) care of patients.

Emerging Racial Disparities in Outpatient Utilization of Total Joint Arthroplasty. J Arthroplasty 2022; 37:2116-2121. [PMID: 35537609 DOI: 10.1016/j.arth.2022.05.008] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 04/10/2022] [Accepted: 05/03/2022] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Racial and ethnic disparities within the field of total joint arthroplasty (TJA) have been extensively reported. To date, however, it remains unknown how these disparities have translated to the outpatient TJA (OP-TJA) setting. The purposes of this study were to compare relative OP-TJA utilization rates between White and Black patients from 2011-2019 and assess how these differences in utilization have evolved over time. METHODS We conducted a retrospective review from 2011-2019 using the National Surgical Quality Improvement Program (NSQIP). Differences in the relative utilization of OP (same-day discharge) versus inpatient TJA between White and Black patients were assessed and trended over time. Multivariable logistic regressions were run to adjust for baseline patient factors and comorbidities. RESULTS During the study period, Black patients were significantly less likely to undergo OP-TJA when compared to White patients (P < .001 for both outpatient total knee arthroplasty and outpatient total hip arthroplasty [OP-THA]). From 2011 to 2019, an emerging disparity was found in outpatient total knee arthroplasty and OP-THA utilization between White and Black patients (eg, White versus Black OP-THA: 0.4% versus 0.6% in 2011 compared with 10.2% versus 5.9% in 2019, Ptrend < .001). These results held in all adjusted analyses. CONCLUSION In this study we found evidence of emerging and worsening racial disparities in the relative utilization of OP-TJA procedures between White and Black patients. These results highlight the need for early intervention by orthopaedic surgeons and policy makers alike to address these emerging inequalities in access to care before they become entrenched within our systems of orthopaedic care.

Abstract
Maximizing hemostasis during total knee replacement procedures remains a key challenge in current practice. Bipolar sealer technology achieves intraoperative hemostasis through tissue sealing and coagulation with adjustable radio frequency energy and a saline-irrigated tip. Optimal surgical site hemostasis is important to avoid potential complications such as hemarthrosis, wound drainage, increased pain, delayed discharge, and readmissions. The aim of this study is to evaluate the safety and effectiveness of the bipolar sealer device in primary knee replacement in the largest consecutive series to date. A consecutive, treatment-control series of subjects who underwent a primary total knee arthroplasty (TKA) utilizing a bipolar sealer for hemostasis, one subgroup with concomitant tranexamic acid (TXA) administration (n = 1599) and one subgroup without TXA administration (n = 3582), compared with a control group of primary TKA under tourniquet only (n = 667). Statistical analyses were performed through two-tailed unpaired t-tests. There was less total postoperative drain output and a lower overall transfusion rate in the bipolar sealer group (807ml ± 428) (2.5%) than the tourniquet only group (1290 ± 658, p = 0.001) (8.4%, p = 0.0001), respectively. Drainage output in bipolar sealer + TXA (450 ± 297 ml) was lower than the other two groups (bipolar sealer 807 ± 428 mL, p = 0.0001; tourniquet only 1290 ± 658 ml, p = 0.0001). The bipolar sealer group had a higher hematocrit at postoperative day 1 (POD1) (bipolar sealer: 33.1 ± 4.3 cc, tourniquet only: 32.5 ± 4.3 cc, p = 0.001) and at discharge (POD2, bipolar sealer: 31.5 ± 3.7 cc, tourniquet only: 30.2 ± 3.9 cc, p = 0.0001). There were zero reported serious adverse events related to hemostasis management in any group. The bipolar sealer system is a safe and effective instrument to achieve intraoperative hemostasis during primary TKA. The bipolar sealer group required significantly fewer postoperative blood product transfusions and maintained a higher hematocrit concentration at the time of discharge compared with subjects treated solely with tourniquet mediated hemostasis. Addition of TXA to local hemostasis methods may further reduce blood loss and transfusion requirements. LEVEL OF EVIDENCE: This is a Level III study.

J Arthroplasty 2022; 37:1715-1718. [PMID: 35405264 DOI: 10.1016/j.arth.2022.04.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 04/04/2022] [Accepted: 04/05/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND In January 2018, the Centers for Medicare and Medicaid Services removed total knee arthroplasty (TKA) from the Inpatient Only (IPO) list. This study aimed to compare patient-level payments in TKA cases with a length of stay (LOS) <2 midnights before and after removal of TKA from IPO list. METHODS In this retrospective cohort study, all Medicare patients who received a primary elective TKA from 2016-2019 with a LOS <2 midnights at an academic tertiary center were identified. Total and itemized charges and patient-level payments were compared between eligible TKA cases performed in 2016-2017 and those in 2018-2019. There were 351 eligible TKA cases identified: 151 in 2016-2017 and 200 in 2018-2019. RESULTS The percentage of patients making any out-of-pocket payment increased in 2018-2019 from 2016-2017 (51.0% versus 10.6%), as did median patient-level payment ($7.30 [range, $0.00-$3,389] versus $0.00 [range, $0.00-$1,248], P < .001 for both). A greater proportion of patients in 2018-2019 paid $1-$50 than in 2016-2017 (37.5% versus 1.3%, P < .001) with no change in the proportion of patients who made payments >$50. Total charges were less in 2018-2019 than in 2016-2017 (P = .001). Charges for drugs, laboratory tests, admissions/floor, and therapies decreased in 2018-2019, whereas charges for the operating room and radiology increased (P < .001 for all). CONCLUSION Patients receiving outpatient TKA in 2018-2019 were more likely to have out-of-pocket payments than patients with comparable hospital stay who were designated as inpatients, although most of these payments were less than $50.

Abstract
Background The length of hospital stay after lower limb arthroplasty has rapidly decreased in the last decade, largely in part due to the rise of improved perioperative protocols, but also as a response to the increased economic demand associated with the rapid growth in hip and knee arthroplasty procedures. In line with this, the development of a new pathway after lower limb arthroplasty that allows for the surgery to be performed in an outpatient setting and permits for same-day discharge after the procedure is increasingly being offered. Although costs and complications between the inpatient and outpatient models have been compared, there appears to be little known about the effects on a patient’s physical function after undergoing hip or knee outpatient arthroplasty. Therefore, this systematic review aims to explore the available evidence for the effect on functional outcomes following inpatient versus outpatient hip or knee arthroplasty. Methods This systematic review adhered to the PRISMA guidelines and was prospectively registered (https://osf.io/8bfae/). An electronic search of three online databases (PubMed, CINAHL and EMBASE) was conducted to identify eligible studies. All studies investigating inpatient and outpatient comparator groups, for a population of patients undergoing hip or knee arthroplasty, that assessed one or more functional outcomes, were included. A methodological quality appraisal was undertaken for the final studies contained in this review. A narrative synthesis of results is described along with quantitative outcomes presented in tables and figures. Results A total of seven studies containing 1,876 participants were included in this review. Four studies assessed a THA population, two assessed TKA and one assessed both. Functional outcomes varied, with 20 different functional outcomes utilised, of which 18 were patient-reported tools. Results of functional outcomes offered mixed support for both inpatient and outpatient pathways. Conclusions The results of this review suggest that outpatient or inpatient pathway selection for hip or knee arthroplasty should not be based on the superiority of functional outcomes alone. However, given there is growing evidence in support of an outpatient pathway in select patients with respect to cost savings and without any increase in complications, it could be proposed that an equivalency of post-operative function between the two settings makes same-day discharge favourable.

Abstract
Background: The interest in ambulatory total hip arthroplasty (THA) has increased recently due to a national focus on value-based care and improved rapid recovery protocols. Purpose: We sought to determine if surgical approach had an effect on discharge outcomes in outpatient THA. Methods: We performed a retrospective cohort study examining patients who underwent unilateral THA at a single institution using a standardized perioperative care pathway who were discharged home within 24 hours. In total, we compared 106 patients who underwent THA using the direct anterior approach (ATHA) and 90 patients who underwent THA using the posterior approach (PTHA). Univariate and multivariable analyses were used to compare time to ambulation, length of surgery, readmissions, and 90-day complications. Results:Time to ambulation in the ATHA and PTHA groups was 3.9 hours and 4.1 hours, respectively, and time to discharge was 5.9 hours and 6.0 hours, respectively. Length of surgery was shorter in the ATHA group than in the PTHA group (78 minutes vs 86 minutes, respectively). Complications occurred in 3 patients (3%) in the ATHA group vs 4 patients (4%) in PTHA group. In both groups, early ambulation (within 5 hours) predicted earlier time to discharge. Surgical approach was not associated with time to ambulation or time to discharge on multivariable analysis. Conclusion: In this retrospective study, outpatient THA was feasible in a well-selected population of patients undergoing anterior or posterior approaches. Further study is warranted.

Total Joint Arthroplasty at a Novel “Hyperspecialty” Ambulatory Surgical Center With Extended Care Suites is as Safe as Inpatient Arthroplasty. Arthroplast Today 2022; 16:242-246.e1. [PMID: 36092129 PMCID: PMC9458896 DOI: 10.1016/j.artd.2022.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 04/26/2022] [Accepted: 05/06/2022] [Indexed: 11/20/2022] Open
Abstract
Background New “hyperspecialty” ambulatory surgical centers (HASCs) have been introduced to deliver safe and cost-efficient care, allowing patients to spend additional nights in an extended care suite before discharge. This study compared the 90-day complications and readmissions of total joint arthroplasty (TJA) at an HASC and inpatient TJA at a tertiary hospital. Methods We retrospectively reviewed 1365 primary, unilateral, TJAs (658 total hip arthroplasty, 707 total knee arthroplasty) performed at 4 HASCs in 2017-2021. Following their outpatient procedure, patients were discharged to an extended care suite staffed full-time by nurses and physical therapists. These patients were matched 1:1 with 1365 inpatient TJAs (628 total hip arthroplasty, 737 total knee arthroplasty) based on demographics, joint, and American Society of Anesthesiologists (ASA) score. Ninety-day complications and readmissions were compared. Results The mean age was 60.0 ± 9.8 years and 59.4 ± 8.1 years in the inpatient and outpatient groups, respectively (P = .106). There was no difference in ASA≥3 patients (16.4% vs 17.7%; P = .387) and operative time (86.9 ± 31.8 vs 88.7 ± 27.9 minutes; P = .118). Five patients (0.4%) in the outpatient group were transferred to an acute hospital. When comparing 90-day outcomes between the inpatient and outpatient groups, there was no difference in pulmonary embolism (0.1% vs 0.0%; P = .317), mechanical complications (0.3% vs 0.7%; P = .165), periprosthetic joint infections (0.5% vs 1.1%; P = .092), or readmissions (1.2% vs 1.5%; P = .513). A subgroup analysis of ASA≥3 patients yielded similar findings. Conclusions Patients undergoing outpatient TJA at a novel HASC had similar complication and readmission rates as those undergoing TJA at a tertiary hospital. Based on these data, such facilities seem appropriate for the care of outpatient TJA patients with ASA<4.

Mepivacaine Versus Bupivacaine Spinal Anesthesia for Primary Total Joint Arthroplasty: A Systematic Review and Meta-Analysis. J Arthroplasty 2022; 37:1396-1404.e5. [PMID: 35306162 DOI: 10.1016/j.arth.2022.03.031] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 02/28/2022] [Accepted: 03/07/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Mepivacaine is an intermediate acting amide local anesthetic that can be used for neuraxial anesthesia in total joint arthroplasty (TJA) with a shorter duration of action (1.5-2 hours) compared to the more commonly used local anesthetic bupivacaine. The purpose of this study was to perform a systematic review and meta-analysis comparing bupivacaine and mepivacaine spinal anesthesia during elective TJA and the surgical outcomes of the time to full neurologic motor return, pain, mobility, length of stay (LOS), and complications including transient neurologic symptoms and urinary function. METHODS PubMed, Ovid MEDLINE, and Ovid Embase were screened for "arthroplasty, spinal anesthesia, bupivacaine, and mepivacaine," in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 159 studies were screened and 5 studies were evaluated. Data were compared regarding motor function return, mobility (distance ambulated), pain (visual analog scale [VAS]), LOS, and postoperative complications. RESULTS Full-text screening yielded 5 studies (3 randomized controlled trials and 2 retrospective cohort studies), with a total of 1,550 patients. Mepivacaine spinals had an earlier return to motor function (154 minutes vs 170 minutes, 95% CI: [-31.6, -0.9], P = .04), shorter LOS (25.95 hours vs 29.96 hours, 95% CI: [-6.8, -1.2], P = .01), and decreased urinary retention (7.15% vs 10.58%, 95% CI: [-6.3%, -0.6%], P = .02) with no differences in pain (VAS 3.57 vs 3.68, 95% CI: [-2.1, 1.9], P = .90) or distance ambulated (94.2 ft vs 89.1 ft, 95% CI: [-15, 25.2], P = .60) compared to bupivacaine spinal anesthesia. CONCLUSIONS The method of anesthesia administration has been an increasing area of focus for quicker and safer recovery to allow for early ambulation and facility discharge. The rapid recovery facilitated by mepivacaine may further enable outpatient TJA and enhance patient recovery. LEVEL OF EVIDENCE III.

Social Determinants of Health in Total Hip Arthroplasty: Are They Associated With Costs, Lengths of Stay, and Patient Reported Outcomes? J Arthroplasty 2022; 37:S422-S427.

Abstract
BACKGROUND Social determinants of health (SDOH) may play a larger role in predicting patient outcomes as outpatient total hip arthroplasty (THA) expands. We specifically examined the association between SDOH and patient metrics (demographics and comorbidities) for: (1) 30-day post-discharge costs of care; (2) lengths of stay (LOS); and (3) patient-reported outcomes (Hip Disability and Osteoarthritis Outcomes Score for Joints Replacement (HOOS JR)). METHODS Medicare patients who underwent primary THA between 2018 and 2019 were identified. Those who had complete social determinant data were included (n = 136). Data elements were drawn from institutional, regional, and government databases, as well as the Social Vulnerability Index (SVI). Multiple regression analyses were performed to determine SDOH and baseline comorbidities associations with costs, LOS, and HOOS JR scores. RESULTS Various SDOH factors were associated with higher 30-day costs, including residing in a food desert ($53,695 ± 15,485; P < .001) and the following SVI themes: 'Minority Status and Language' ($24,075 ± 9845; P = .01) and 'Housing and Transportation' ($16,190 ± 8501; P = .06), although the latter did not meet statistical significance. Baseline depression was associated with longer LOS (P = .02), while none of the other SDOH or patient metrics affected LOS. No relationships were observed between SDOH and HOOS JR changes from baseline. CONCLUSION Patients who live in food deserts and have minority status had higher costs of care after primary THA. Poor housing and transportation may also increase costs, albeit insignificantly. These results highlight the utility of assessing SDOH-related risk factors to optimize post-operative outcomes, with potential implications for bundled care.

Abstract
BACKGROUND The volume of outpatient total knee arthroplasty (TKA) has increased with advances in perioperative protocols, patient selection, and recent policy changes regarding insurance authorization. This study analyzed 30-day outcomes from a national database to better understand risk factors for delayed discharge (length of stay [LOS] ≥1), readmission, and reoperation after outpatient TKA. METHODS The National Surgical Quality Improvement Program (NSQIP) database was utilized to collect TKA (CPT 27447) billed as outpatient surgery performed from 2013 to 2018. Patient demographics, comorbidities, and short-term outcomes were collected and compared in LOS 0 versus LOS ≥1 cohorts. Subgroup analysis was completed for TKA performed in 2018, after the Center for Medicare Services removal of TKA from the inpatient-only list. RESULTS A total of 13,669 patients had outpatient TKA performed from 2013 to 2018. Most patients had LOS ≥1 day (77.1%). The LOS 0 cohort demonstrated a lower 30-day readmission rate (1.8%) compared to LOS ≥1 (2.8%), P > .01. Both groups demonstrated a low 30-day reoperation rate, LOS 0 (0.7%) and LOS ≥1 (1.1%), P = .05. Regression analysis demonstrated risk factors for LOS ≥1 day included COPD, ASA ≥3, age >75, and BMI >35 kg/m2. Regression analysis demonstrated male gender, age >75, ASA ≥3, and albumin <3.5 g/dL were risk factors for readmission. Hypertension was a risk factor for 30-day reoperation. CONCLUSION Risk factors for LOS ≥1 day include age >75, ASA ≥3, BMI >35 kg/m2. In addition, BMI >35 kg/m2 was a risk factor for readmission and reoperation. These findings reinforce appropriate patient selection when considering outpatient TKA.

Orthopaedic surgeons' perspective on the implementation of outpatient hip and knee arthroplasty - Results of a nationwide survey. J Clin Orthop Trauma 2022; 29:101873. [PMID: 35542179 PMCID: PMC9079766 DOI: 10.1016/j.jcot.2022.101873] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 04/19/2022] [Indexed: 10/18/2022] Open
Abstract
Background Outpatient joint arthroplasty (OJA) for the hip and knee is gaining popularity among orthopaedic surgeons worldwide. The purposes of this study were to (1) assess the proportion of Dutch orthopaedic surgeons who perform OJA; (2) identify surgeons' willingness to implement OJA in the future; (3) identify reasons and barriers to implement OJA; and (4) gather surgeon's perspective on the implementation of OJA. Methods A 20-item survey was developed and administered by email to orthopaedic surgeons who are a member of the Dutch Hip Society and Dutch Knee Society. Survey response rate was 40% (N = 123). Results Twenty-two respondents (18%) already implemented OJA, and 46% of respondents (who don't perform OJA) were interested to implement OJA in the future. Reasons to perform OJA included own positive experiences (82%), available evidence (77%) and patients' request (77%). Proponents' and opponents' view on safety and added value conflicted with each other. Other barriers included patient selection and organizational related (e.g., multidisciplinary support). Surgeons' view on evolution and relevance of OJA significantly differed by respondents who perform OJA versus respondents who don't perform OJA. Most respondents agreed with one another that the healthcare institution benefits most from OJA, and that optimization of the arthroplasty pathway could be reached through better patient education and -participation (e.g., eHealth, wearables). Conclusion One in five respondents currently implement OJA pathways, and about half of the remaining respondents are interested to implement OJA in the future. OJA-opponents aren't convinced of the value and safety of OJA, despite accumulating evidence supporting OJA. Future research should inform patient-selection and -acceptance and organizational implementation.

[PMID: 35093549 DOI: 10.1016/j.arth.2022.01.058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 01/18/2022] [Accepted: 01/21/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Surgical specialty hospitals provide patients, surgeons, and staff with a streamlined approach to elective surgery but may not be equipped to handle all complications arising postoperatively. The purpose of this study is to evaluate the immediate postoperative and 90-day outcomes of patients who were transferred from a high-volume specialty hospital following primary total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS All patients who were admitted to one orthopedic specialty hospital for primary THA or TKA between January 2015 and December 2019, and subsequently transferred to a tertiary care hospital, were identified and propensity matched to nontransferred patients. Emergency department visits, complications, readmissions, mortality, and revisions within 90 days of surgery were identified for each group. RESULTS There were 26 TKAs (0.78%) and 20 THAs (0.48%) transferred, representing 0.62% of all primary THAs and TKAs performed over the study duration. Arrhythmia and chest pain were the most common reasons for transfer. Ninety-day readmissions were significantly higher in the transfer group (15.2% vs 4.3%, P = .020) with an odds ratio for readmission after transfer of 3.9 (95% confidence interval 1.3-12.4). Overall complications and orthopedic complications did not differ significantly, although transferred patients had a higher rate of medical complications (13.0% vs 2.2%, P = .008) with an odds ratio of 6.7 (95% confidence interval 1.6-28.2). CONCLUSION Transfer from a specialty hospital is rarely required following primary TKA and THA. Although not at increased risk for orthopedic complications, these transferred patients are at increased risk for readmissions and medical complications within the first 90 days of their care, necessitating increased vigilance.

Abstract
BACKGROUND Although total hip arthroplasty (THA) and total knee arthroplasty (TKA) are transitioning to surgery centers, there remain limited data on trends, comorbidities, and complications in patients discharged the same day of surgery. In addition, many studies are limited to the Medicare population, excluding a large proportion of outpatient surgery patients. METHODS Primary, elective THA/TKA cases between 2010 and 2017 were retrospectively identified using the PearlDiver All-Payer Database and separated based on surgery as well as same-day discharge (SDD) or non-SDD. Data were collected on demographics, rates, comorbidities, and complications. Multivariable logistic regression determined adjusted odds ratios (ORs) for 90-day complications requiring readmission for each group. RESULTS In total, 1,789,601 (68.8% TKA, 31.2% THA) patients were identified where 2.9% of TKAs and 2.2% of THAs were SDD. Annual SDD rates are increasing, with a 15.8% mean annual change for SDD-THA and 11.1% for SDD-TKA (P < .001). SDD patients were younger with fewer comorbidities (P < .001). Regression analysis showed an overall slightly higher OR of complications requiring readmission for SDD-TKA vs non-SDD-TKA (OR 1.14, 95% confidence interval [CI] 1.07-1.21, P < .001). There was no significant difference for SDD-THA vs non-SDD-THA (OR 1.03, 95% CI 0.94-1.13, P = .49). In univariate analysis, SDD-THA vs SDD-TKA had more mechanical complications (P < .001), but less pulmonary embolisms (P < .001). Regression analysis showed a slightly higher risk of complications for SDD-THA vs SDD-TKA (OR 1.19, 95% CI 0.99-1.44, P = .05). CONCLUSION The prevalence of SDD is rising. SDD-THA is increasing more rapidly than SDD-TKA. SDD patients are generally younger with fewer comorbidities. SDD-TKA has slightly higher odds of complications requiring readmission than non-SDD-TKA. SDD-THA and SDD-TKA have different complication profiles.

Abstract
ABSTRACT Despite trends showing increases in the utilization of outpatient (OP) ambulatory surgery centers (ASCs) and decreases in the utilization of inpatient (IP) facilities for total knee arthroplasty (TKA) and total hip arthroplasty (THA), little is known about opioid prescribing for these procedures between each setting. This study evaluated differences in opioid prescribing and consumption between OP ASC and IP settings for elective TKA and THA surgeries over a 1-year period. Data collection also included pain and satisfaction of pain control postsurgery. In an OP ASC, analysis revealed a significant decrease in pills prescribed (p < .001, p < .001) and consumed (p < .001, p < .001) for TKA and THA, respectively. There was a significant decrease in the morphine equivalence units prescribed (p < .001, p < .001) and consumed (p < .001, p < .001) for TKA and THA, respectively. For TKA, pain was significantly lower (p = .018) and satisfaction of pain control was significantly higher (p = .007). For THA, pain (p = .374) and satisfaction of pain control (p = .173) were similar between the settings. Benefits of performing these surgeries in an OP ASC setting are patients having similar or lower levels of pain and having similar or higher satisfaction of pain control. Patients are also prescribed and consume less opioids. This has important implications for healthcare systems.

Abstract
The number of annual total joint arthroplasties (TJA) is increasing. Periprosthetic joint infections (PJI) occur when there is infection involving the prosthesis and surrounding tissue, which has the potential to develop into sepsis if left untreated. Sepsis in patients who have undergone TJA is life threatening and requires urgent treatment. If sepsis is due to PJI, the focus should be on early intravenous antibiotics with aspiration as soon as possible to diagnose the infection. Patients who develop sepsis after surgery for PJI are particularly at high risk for mortality and need to be treated in the intensive care unit.

Abstract
Background Patient activation and engagement can improve outcomes of medical and surgical care by increasing involvement of patients in their care plan. We designed a digital engagement tool to improve surgical cancellation and post-surgical outcomes for adult patients undergoing total joint replacements by providing patient education materials via email or text, in small increments throughout the perioperative period. Methods We assessed the tool's impact using a quasi-experimental design comparing patients scheduled for surgery January–June 2017 (pre-intervention) versus January–June 2018 (post-intervention). Post-intervention patients with digital contact information in the medical record were automatically enrolled. We extracted de-identified administrative data for all patients during both time periods and utilized an intent-to-treat approach including all post-intervention patients regardless of enrollment. Surgical cancellation and post-surgical outcomes (length of stay, discharge to home and revisits and readmissions) were compared between periods using adjusted regression models. We also examined associations between measures of engagement with the intervention and outcomes. Results A total of 2027 joint replacement patients were included (720 hip replacements; 1307 knee replacements). Adjusting for gender, age and insurance type, both hip and knee patients in the post-intervention group were more likely to have a cancelled surgery, but cancellations were less likely to be on the day of surgery compared to pre-intervention patients. Post-intervention patients were also less likely to have length of stay >2 days. Forty- three per cent of hip and 47% of knee patients in the post-period received the intervention and most were highly engaged. Higher engagement was associated with lower odds of surgical cancellation, shorter stays and higher odds of discharge home. Conclusion Findings suggest that utilization of a digital patient engagement tool translates into improved hospital efficiency and patient outcomes, particularly for those highly engaged.

Abstract
Background Patient selection for outpatient total joint arthroplasty (TJA) is important for optimizing patient outcomes. This study develops machine learning models that may aid in patient selection for outpatient TJA based on medical comorbidities and demographic factors. Methods This study queried elective total knee arthroplasty (TKA) and total hip arthroplasty (THA) cases during 2010-2018 in the American College of Surgeons National Surgical Quality Improvement Program. Artificial neural network models predicted same-day discharge and length of stay (LOS) fewer than 2 days (short LOS). Multiple linear and logistic regression analyses were used to identify variables significantly associated with predicted outcomes. Results A total of 284,731 TKA cases and 153,053 THA cases met inclusion criteria. For TKA, prediction of short LOS had an area under the receiver operating characteristic curve (AUC) of 0.767 and accuracy of 84.1%; prediction of same-day discharge had an AUC of 0.802 and accuracy of 89.2%. For THA, prediction of short LOS had an AUC of 0.757 and accuracy of 70.6%; prediction of same-day discharge had an AUC of 0.814 and accuracy of 78.8%. Conclusion This study developed machine learning models for aiding patient selection for outpatient TJA, through accurately predicting short LOS or outpatient vs inpatient cases. As outpatient TJA expands, it will be important to optimize preoperative patient selection and effectively screen surgical candidates from a broader patient population. Incorporating models such as these into electronic medical records could aid in decision-making and resource planning in real time.

Abstract
PURPOSE OF REVIEW This article considers how postacute care (PAC) facilities such as skilled nursing facilities, inpatient rehabilitation facilities and long-term care hospitals could represent an opportunity for outpatient surgical facilities to improve patient care. In order to understand how these facilities interact with outpatient surgical services, it is first necessary to understand the types of facilities that provide PAC. RECENT FINDINGS The significant costs associated with PAC have led to some proposed regulatory changes. Evidence examining postacute costs following total joint replacement has indicated that these costs may be decreased with cooperative efforts between perioperative physicians and PAC facilities. However, the lack of currently published data on the interaction between outpatient surgery and inpatient PAC facilities creates a need to explore how greater cooperation between these types of facilities could lead to improvements in patient care. SUMMARY PAC facilities are inpatient facilities focused on the rehabilitation of patients recovering from an acute illness or surgical intervention. This article seeks to provide ambulatory practitioners a fundamental understanding of PAC as a starting point for future collaborative efforts with PAC facilities; improving care for patients referred to and from PAC facilities for outpatient surgical care.

Abstract
BACKGROUND Unicompartmental knee arthroplasty (UKA) is a common procedure for unicompartmental knee arthritis, often resulting in pain relief and improved function. The demand for total knee arthroplasty in the U.S. is projected to grow 85% between 2014 and 2030, and the volume of UKA procedures is growing 3 to 6 times faster than that of total knee arthroplasty. The purpose of the present study was to examine the safety of outpatient and inpatient UKA and to investigate changes over time as outpatient procedures were performed more frequently. METHODS Patients who underwent UKA from 2005 to 2018 as part of the National Surgical Quality Improvement Program were identified. Patients were divided into an early cohort (5,555 patients from 2005 to 2015) and late cohort (5,627 patients from 2016 to 2018). Outpatient status was defined as discharge on the day of surgery. Adverse events within 30 days postoperatively were compared, with adjustment for baseline characteristics with use of standard multivariate regression and propensity-score-matching techniques. RESULTS Among the 5,555 cases in the early cohort, the rate of surgical-site infection was lower for inpatient (0.84%) compared with outpatient UKA (1.69%; adjusted relative risk [RR] for inpatient, 0.5; 95% confidence interval [CI], 0.2 to 1.0; p = 0.045); no other significant differences were identified. Among the 5,627 cases in the late cohort, inpatient UKA had higher rates of any complication (2.53% compared with 0.95% for outpatient UKA; adjusted RR for inpatient, 2.5; 95% CI, 1.4 to 4.3; p = 0.001) and readmission (1.81% compared with 0.88% for outpatient UKA; adjusted RR for inpatient, 2.0; 95% CI, 1.1 to 3.5; p = 0.023). In the propensity-score-matched comparison for the late cohort, inpatient UKA had a higher rate of any complication (RR for inpatient, 2.0; 95% CI, 1.0 to 4.0; p = 0.049) and return to the operating room (RR for inpatient, 4.3; 95% CI, 1.4 to 12.6; p = 0.009). Although the rate of readmission was almost twice as high among inpatients (1.67% compared with 0.84% for outpatients; RR for inpatient, 2.0; 95% CI, 1.0 to 4.1; p = 0.059), this difference did not reach significance with the sample size studied. There was a significant reduction in the overall rate of complications over time (3.44% in the early cohort compared with 2.11% in the late cohort; adjusted RR for late cohort, 0.7; 95% CI, 0.5 to 0.8; p = 0.001), with a more than fourfold reduction among outpatients (3.95% in the early cohort compared with 0.95% in the late cohort; adjusted RR for late cohort, 0.3; 95% CI, 0.1 to 0.5; p < 0.001). CONCLUSIONS Outpatient UKA was associated with a lower risk of complications compared with inpatient UKA when contemporary data are examined. We identified a dramatic reduction in complications across the early and late cohorts, suggesting an improvement in quality over time, with the largest improvements seen among outpatients. This shift may represent changes in patient selection or improvements in perioperative protocols. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Purpose The purpose of this study was to compare early post-operative complications and readmissions between total joint arthroplasty (TJA) patients completed as outpatient versus inpatient procedures. Methods A review of 2648 primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients between 2015 and 2019 was performed. Patients who underwent same-day discharge were matched to the inpatient cohort using age, gender, body mass index (BMI), and smoking status. American Society of Anesthesiologists (ASA) Scores were calculated for the two cohorts. A total of 234 matched pairs (468 knees) for the TKA cohort and 132 matched pairs (264 hips) for the THA cohort were identified. Data was collected for six months after surgery for 30- and 90-day readmissions, the occurrence of reoperations, revisions, deep vein thrombosis (DVT), pulmonary embolism (PE), falls within 90 days, fractures, infections and dislocations. Results The average age for TJA patients was 60 years, with an average BMI of 32, 58% females, and 51.5% who reported never smoking. Post-operative fall risk was higher in the inpatient TKA cohort compared to the same-day cohort (3.0% vs 0.4%, p = 0.032) as was the risk of 90-day readmission (6.0% vs 2.1%, p = 0.034), respectively. These differences were also observed in the combined THA and TKA cohorts. Conclusions We report no increase in reoperations, revisions, 30 or 90-day readmissions, deep vein thrombosis (DVT), pulmonary embolism (PE), fractures, infections or dislocations in the outpatient cohort. Early complications and readmissions of patients who underwent TJA as same-day surgeries compared favorably to a matched cohort of inpatients.

Abstract
Introduction: High-percentage outpatient total joint arthroplasty (TJA) performed in a safety net hospital system has not been described. A rapid recovery protocol (RRP) was instituted at our safety net hospital that allowed eventual transition to outpatient TJA. Methods: Retrospective review of all primary total knee and hip arthroplasty performed by a single surgeon (RR) using an RRP was performed. The initial cohort of patients was monitored overnight with the goal of next-day discharge (n = 57), and as the RRP evolved, the subsequent cohort of patients had the possibility of same-day discharge (PSDD, n = 61). Outcome measures included the rate of same-day discharge in the PSDD cohort and short-term adverse event rates. Results: In the PSDD cohort, 86.9% (n = 53) of patients were successfully discharged on the day of surgery, and hospital length of stay was decreased by 17.7 hours (13.5 versus 31.2 hours, P < 0.0001). Comparing the next-day discharge and PSDD groups, no significant differences were found in 30-day emergency department visits (5.3% versus 3.3%, P = 0.67), 90-day complications (15.8% versus 13.1%, P = 0.79), 90-day readmissions (0% versus 3.3%, P = 0.50), or 90-day revision surgeries (0% versus 3.3%, P = 0.50). Conclusions: This study demonstrates that the transition to outpatient TJA can be successfully performed in a safety net hospital system without increasing short-term adverse events.
