Chen M, Raji Y, Sivasundaram L, Voos JE. Risk Factors of Emergency Department Utilization After Outpatient Surgery for Sports-Related Injuries. J Am Acad Orthop Surg 2024; 32:611-626. [PMID: 38147678 DOI: 10.5435/jaaos-d-22-00715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 11/02/2023] [Indexed: 12/28/2023] Open
Abstract
INTRODUCTION The purpose of this study was to identify the most common reasons for and risk factors associated with postoperative emergency department (ED) utilization after orthopaedic procedures for sports-related injuries. METHODS Using the 2014 to 2016 New York and Florida State Databases from the Healthcare Cost and Utilization Project, outpatient procedures for sports-related injuries were identified. Patient records were tracked across care settings within each state to determine the rate and reasons of postoperative ED utilization within 90 days after the index surgery. Multiple logistic regression models were used to identify risk factors associated with ED visits at 0 to 7 days, 8 to 30 days, 31 to 90 days postoperatively. RESULTS A total of 28,192 surgery visits for sports-related injuries were identified, with knee arthroscopy with partial meniscectomy (18.48%) and arthroscopic anterior cruciate ligament reconstruction (17.04%) as the two most common procedures treating sports injuries. The overall postoperative ED utilization rates were 1.6% (0 to 7 days postoperative), 1.3% (8 to 30 days) and 2.1% (31 to 90 days). The main cause of ED visits was markedly different during each postoperative period: mainly musculoskeletal pain (36.3%) during 0 to 7 days, either musculoskeletal pain (17%) or injury (16.6%) during 8 to 30 days, and injury (24.2%) during 31 to 90 days. Sports with the highest ED utilization in descending order were basketball, football, ice/snow sports, walking/running, cycling, and soccer. Relative to open procedures, arthroscopic procedures were 0.71 times as likely to result in a postoperative ED visit. Independent predictors of ED utilization up to 90 days postoperatively included renal failure, chronic pulmonary disease, psychosis, diabetes, and alcohol abuse. DISCUSSION Rate of ED utilization after outpatient surgery for sports-related injuries is low (<2.2%), with postoperative musculoskeletal pain and reinjury as the two most common causes, highlighting the importance of postoperative pain management and injury prevention. Arthroscopic procedures showed markedly lower ED utilization compared with open surgery, although not indicative of overall superiority. LEVEL OF EVIDENCE III, Retrospective Cohort Study.

Int J Surg 2022; 104:106759. [PMID: 35811014 DOI: 10.1016/j.ijsu.2022.106759] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Revised: 06/17/2022] [Accepted: 06/27/2022] [Indexed: 11/15/2022]
Abstract
BACKGROUND Limited data exist on readmission following knee arthroplasty (KA) in countries without well-established referral or extended care systems. This study aimed to investigate the incidence, patterns and risk factors for readmission following KA in China. MATERIAL AND METHODS In this national retrospective cohort study, we reviewed 167,265 primary KAs registered in the Hospital Quality Monitoring System in China between 2013 and 2018. Readmissions after KA within 30 and 90 days were evaluated. The causes for readmission were identified and classified as surgical or medical. The potential risk factors of readmission were assessed using multivariable logistic regression. RESULTS 4017 (2.4%) patients readmitted within 30 days, and 7258 (4.3%) patients readmitted within 90 days. The readmission rate exhibited a downward trend during the period from 2013 to 2018 (2.7%-2.3% for 30-day readmission; 4.5%-4.2% for 90-day readmission). Surgical causes contributed to 54.3% readmissions within 30 days and 47.3% readmissions within 90 days. Wound infection/complication, joint pain, and thromboembolism were the most frequently reported reasons for surgical readmission. Older age, male sex, single marital status, non-osteoarthritis indication, a high comorbidity index, non-provincial hospitals, low hospital volume, and longer length of stay were associated with an increased risk of readmission. The geographic regions of hospitals contributed greatly to the variety of readmissions. CONCLUSION The readmission rate following KA decreased from 2013 to 2018. Surgery-related causes, especially wound infection/complication and pain, accounted for a large proportion. Both patient and hospital factors were associated with readmissions. Improved primary care and targeted measures are needed to help further prevent readmissions and optimize resource utilization.

Abstract
Patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension (PH) are at increased risk when undergoing anesthesia and major surgery. Data on outcomes for elective orthopedic surgery in patients with PH are limited. A patient pathway was established to provide access to elective lower limb arthroplasty. This included assessment of orthopedic needs, fitness for anesthesia, preoperative optimization, and intra- and postoperative management. Patient data were retrospectively retrieved using patient's hospital records. Between 2012 and 2020, 29 operations (21 total hip replacements [THRs], 7 total knee replacements [TKRs], 1 total hip revision) were performed in 25 patients (mean age: 67 years). Perioperatively, 72% were treated with low-dose intravenous prostanoid. All had arterial lines, and central access and perioperative lithium dilution cardiac output monitoring was used in 86% of cases. Four patients underwent GA, 21 spinal anesthesia, and 4 CSE anesthesia. Supplemental nerve blocks were performed in all patients undergoing general, and 12 of 21 undergoing spinal anesthesia. All were managed in high dependency postoperatively. Hospital length of stay and complication rates were higher than reported in non-PH patients. Perioperative complications included hypotension requiring vasopressors (n = 10), blood transfusion (n = 7), nonorthopedic infection (n = 4), and decompensated right heart failure (n = 1). There was no associated mortality. All implants were functioning well at 6 weeks and subsequent follow-up. EmPHasis-10 quality of score decreased by 5.5 (±2.1) (p = 0.04). A dedicated multiprofessional pathway can be used to safely select and manage patients with PH through elective lower limb arthroplasty.

Abstract
BACKGROUND Transitioning patients from the hospital to home after a total hip or knee arthroplasty is challenging. Severe pain, comorbidities and complex medication regimes have the potential to delay readiness for discharge, increase length of stay (LOS), and cause readmissions. OBJECTIVE The goal of this practice improvement project was to improve patient readiness for discharge after total joint arthroplasty to reduce LOS, prevent emergency department (ED) visits, and prevent hospital readmissions. METHODS This quality improvement project was guided by the Iowa Model and implemented a prepost program implementation evaluation design. Nurses incorporated the Registered Nurse Assessment of Readiness for Hospital Discharge Scale (RN-RHDS) to guide and evaluate discharge education efforts. RESULTS The focused education cohort demonstrated significantly decreased LOS and decreased readmissions compared to the cohort receiving standard education efforts. ED visits were not significantly different amongst cohorts. CONCLUSION This practice improvement project demonstrates successful translation of research into practice. IMPLICATIONS FOR NURSING The use of focused education and the RN-RHDS tool is recommended for nursing to improve patient readiness for discharge and patient outcomes.

Abstract
BACKGROUND Predicting the length of stay (LOS) after total joint arthroplasty (TJA) has become more important with their recent removal from inpatient-only designation. The American College of Surgeons (ACS) National Surgical Quality Improvement Program surgical risk calculator and the CMS' diagnosis-related group (DRG) calculator are two common LOS predictors. The aim of our study was to determine how our actual LOS compared with those predicted by both the ACS and DRG. METHODS 99 consecutive TJA (49 hips and 50 knee procedures) were reviewed in Medicare-eligible patients from four fellowship-trained arthroplasty surgeons. Predicted LOS was calculated using the DRG and ACS risk calculators for each patient using demographics, medical histories, and comorbidities. LOS was compared between the predicted and the actual LOS for both total hip arthroplasty (THA) and total knee arthroplasty (TKA) using paired t-tests. RESULTS Actual LOS was shorter in the THA group vs the TKA group (1.29 days vs 1.46 days, P < .05). The actual LOS of patients at our institution was significantly shorter than both DRG and ACS predictions for both THA and TKA (P < .05). In both the THA and TKA patients, the actual LOS (1.29 and 1.46 day) was significantly shorter than the DRG-predicted LOS (2.15 and 2.15 days) which was significantly shorter than the ACS-predicted LOS (2.9 and 3.14 days). CONCLUSION We found the actual LOS was significantly shorter than that predicted by both the DRG and ACS risk calculators. Current risk calculators may not be accurate for contemporary fast-track protocols and newer tools should be developed.

A Rapid Recovery Protocol Applied to Total Joint Arthroplasty Reduced Readmissions for Surgical but Not Medical Reasons Over a 5-Year Period. HSS J 2021; 17:130-137.

Abstract
Background: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are commonly performed procedures that are expected to continue increasing in demand. Although they are proven to be safe and effective, emergency room (ER) visits or hospital readmissions within 90 days after these procedures account for more than one-third of the total cost of postacute care. Purpose: We sought to identify changes in reasons for 90-day ER visits and readmissions after total joint arthroplasty (TJA) during a 5-year period over which rapid recovery protocols evolved. Methods: We conducted a retrospective cohort study comparing 1980 patients who had undergone TJA from July 2017 to June 2018 with a previously published cohort of 7466 patients who had undergone TJA from July 2013 to June 2017. All procedures were performed at a single institution. Changes in the proportion of patients returning for medical and surgical reasons were compared using univariate analysis. Results: For patients discharged home, the 2017-2018 cohort showed a significant reduction in the proportion of ER visits due to pain and swelling and wound infection and an increase in visits for medical reasons. This cohort had a higher proportion of readmissions for medical reasons. In patients discharged to a skilled nursing facility (SNF), similar reasons for ER visits were observed across time periods, and a decrease in the proportion of readmissions for wound infections was observed in the 2017-2018 cohort. Falls and nausea, vomiting, or diarrhea increased significantly to account for 9.5% of readmissions each in 2017-2018. Conclusion: The results of a comparison of 2 cohorts demonstrate the heterogeneous and dynamic nature of unplanned return-to-hospital events and the importance of patient support throughout the surgical episode. As we strive toward minimizing ER visits and readmissions after TJA, rapid recovery protocols must continue to evolve to address the complexity of this patient population.

Despite Equivalent Medicare Reimbursement, Facility Costs for Outpatient Total Knee Arthroplasty Are Higher Than Unicompartmental Knee Arthroplasty. J Arthroplasty 2021; 36:S141-S144.e1. [PMID: 33358515 DOI: 10.1016/j.arth.2020.11.037] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 10/20/2020] [Accepted: 11/24/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND With the recent removal of total knee arthroplasty (TKA) from the Centers for Medicare and Medicaid Services (CMS) Inpatient Only list, facility reimbursement for outpatient TKA now falls under the Outpatient Prospective Payment System at the same rate as unicompartmental knee arthroplasty (UKA). The purpose of this study was to compare true facility costs of patients undergoing outpatient TKA with those undergoing UKA. METHODS We reviewed a consecutive series of 2310 outpatient TKA and 231 UKA patients from 2018 to 2019. Outpatient status was defined as a hospital stay of less than 2 midnights. Facility costs were calculated using a time-driven, activity-based costing algorithm. Implants, supplies, medications, and personnel costs were compared between outpatient TKA and UKA patients. A multivariate analysis was performed to control for confounding medical and demographic variables. RESULTS When compared with patients undergoing UKA, outpatient TKA patients had higher implant costs ($3403 vs $3081; P < .001) and overall hospital costs ($6350 vs $5594; P < .001). Outpatient TKA patients had a greater length of stay (1.2 vs 0.5 days; P < .001) and greater postoperative personnel costs ($783 vs $166; P < .001) than UKA patients. When controlling for comorbidities, outpatient TKA was associated with a $803 (P < .001) increase in overall facility costs compared with UKA. CONCLUSION Despite equivalent reimbursement from CMS as UKA, outpatient TKA has increased facility costs to the hospital. Although implant costs can vary greatly by institution, CMS should consider appropriately reimbursing outpatient TKA for the additional personnel costs when compared with UKA.

Abstract
» We performed a systematic review and meta-analysis of predictive modeling studies examining the risk of readmission after total hip arthroplasty (THA) and total knee arthroplasty (TKA) in order to synthesize key risk factors and evaluate their pooled effects. Our analysis entailed 15 compliant studies for qualitative review and 17 compliant studies for quantitative meta-analysis. » A qualitative review of 15 predictive modeling studies highlighted 5 key risk factors for risk of readmission after THA and/or TKA: age, length of stay, readmission reduction policy, use of peripheral nerve block, and type of joint replacement procedure. » A meta-analysis of 17 studies unveiled 3 significant risk factors: discharge to a skilled nursing facility rather than to home (approximately 61% higher risk), surgery at a low- or medium-procedure-volume hospital (approximately 26% higher risk), and the presence of patient obesity (approximately 34% higher risk). We demonstrated clinically meaningful relationships between these factors and moderator variables of procedure type, source of data used for model-building, and the proportion of male patients in the cohort. » We found that many studies did not adhere to gold-standard criteria for reporting and study construction based on the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) and NOS (Newcastle-Ottawa Scale) methodologies. » We recommend that these risk factors be considered in clinical practice and future work alike as they relate to surgical, discharge, and care decision-making. Future work should also prioritize greater observance of gold-standard reporting criteria for predictive models.

Abstract
BACKGROUND As short stay and outpatient total joint arthroplasties (TJAs) are more widely adopted, it is important to assess whether reducing length of stay leads to increased emergency department (ED) visits or readmissions. METHODS This is a retrospective review of 1743 primary TJA patients with same-day discharge (SDD) or 1-day length of stay between January and December 2019. Patients who returned to the ED or were readmitted within 30 days of TJA were identified, and chart review was performed to identify their primary reason for revisit. RESULTS Patients discharged on the day of surgery (n = 203, 11.6%) were more likely to be younger (P < .001) and have a lower body mass index (total hip arthroplasty, P = .018; total knee arthroplasty, P < .001) and American Society of Anesthesiologists score (P < .001). The overall rate of return was 6.3%, and 1.3% of patients were readmitted. Controlling for age, gender, body mass index, surgery type, and American Society of Anesthesiologists, patients selected for SDD were not found to be at higher risk of return to the ED compared to 1-day length of stay patients (4.9% vs 6.4%, odds ratio 0.980, 95% confidence interval 0.484-1.984, P = .956). CONCLUSION SDD of eligible patients does not increase the risk of 30-day return to the ED. Continued analysis of risk factors for return and readmission will improve prospective identification of patients who can safely be discharged on the day of surgery, and future quality improvement initiatives should target the most common reasons for ED return.

Abstract
BACKGROUND The objective of this review is to examine the effect of perioperative systemic corticosteroids at varying doses and timings on early postoperative recovery outcomes following unilateral total knee and total hip arthroplasty. The primary outcome was length of stay (LOS). METHODS A systematic review and meta-analysis of randomized controlled trials was performed. MEDLINE, EMBASE, and Cochrane Library databases were searched from inception to June 1, 2020. Studies comparing the outcome of adult patients receiving a systemic steroid to patients who did not receive steroids were included. RESULTS Seventeen studies were included, incorporating 1957 patients. Perioperative corticosteroids reduced hospital LOS (mean difference [MD] = -0.39 days, 95% confidence interval [CI] -0.61 to -0.18). A subsequent dose of corticosteroid at 24 hours further reduced LOS (MD = -0.33, 95% CI -0.55 to -0.11). Corticosteroids resulted in reduced levels of pain on postoperative day (POD) 0 (MD = -1.99, 95% CI -3.30 to -0.69), POD1 (MD = -1.47, 95% CI -2.15 to -0.79), and POD2. Higher doses were more effective in reducing pain with activity on POD0 (P = .006) and 1 (P = .023). Steroids reduced the incidence of PONV on POD1 (log odds ratio [OR] = -1.05, 95% CI -1.26 to -0.84) and POD2, with greater effect at higher doses (P = .046). Corticosteroids did not increase the incidence of infection (P = 1.000), venous thromboembolism (P = 1.000), or gastrointestinal hemorrhage (P = 1.000) but were associated with an increase in blood glucose (MD = 5.30 mg/dL, 95% CI 2.69-7.90). CONCLUSION Perioperative corticosteroids are safe, facilitate earlier discharge, and improve patient recovery following unilateral total knee arthroplasty and total hip arthroplasty. Higher doses (15-20 mg of dexamethasone) are associated with further reductions in dynamic pain and PONV, and repeat dosing may further reduce LOS.

Krueger CA, Courtney PM, Austin MS. Medicare Total Knee Arthroplasty Patients Need Not Stay 2 Midnights for Full Facility Reimbursement. J Arthroplasty 2021; 36:412-415. [PMID: 32950338 DOI: 10.1016/j.arth.2020.08.053] [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: 06/26/2020] [Revised: 08/21/2020] [Accepted: 08/25/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Health care systems are concerned that facility reimbursements will be reduced based on patient length of stay (LOS) of <2 midnights with the removal of total knee arthroplasty (TKA) from the inpatient-only list. The purpose of this study was to evaluate the effect of LOS and postdischarge disposition on facility reimbursement. METHODS We evaluated a consecutive series of 470 primary Medicare TKA patients performed at a single institution from 2018 to 2019. We analyzed facility reimbursement based on patient LOS and discharge disposition. Descriptive statistics were analyzed using chi-square test, analysis of variance, and Student t test calculations. RESULTS Overall, the facility was fully reimbursed in 401 patients (85%) at a mean of $11,169. The facility received full reimbursement for 323 of 326 (99%) patients with an LOS of <2 midnights who were discharged to home at a mean of $11,156. This reimbursement was significantly (P < .001) higher than patients who had an LOS <2 midnights who were discharged with home health (mean, $9773) or to a facility (mean, $10,095). For those with LOS >2 midnights, there was no difference in mean reimbursement among discharge dispositions ($11,202 vs $11,249 vs $11,085, P = .65). CONCLUSION In this study, Medicare TKA patients with LOS <2 midnights were fully reimbursed 99% of the time as an inpatient as long as they are discharged to home without home health or to a rehabilitation facility. Those discharged before 2 midnights who require home health service or inpatient facility are more likely to be reimbursed at a lower penalized rate.

[PMID: 32540306 DOI: 10.1016/j.arth.2020.05.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 05/06/2020] [Accepted: 05/12/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Recent changes to payment models for elective total joint arthroplasty (TJA) have led to increased interest in postdischarge health care utilization. Although readmission has historically been of primary interest, emergency department (ED) presentation is increasingly a point of focus. The purpose of this review was to summarize the available literature pertaining to ED visits after total hip arthroplasty and total knee arthroplasty. METHODS PubMed, MEDLINE, and Embase were searched. Clinical studies reporting rate, reasons, and/or risk factors associated with ED presentation after TJA were included. Pooled return to ED rates were calculated using weighted means. RESULTS Twenty-seven studies (n = 1,484,043) were included. After TJA, the mean 30-day and 90-day rates of ED presentation were 8.1% and 10.3%, respectively. Rates were slightly higher in total knee arthroplasty vs total hip arthroplasty patients at 30 days (11.5% vs 6.5%) and 90 days (10.8% vs 9.7%). The most common reasons for ED presentation after TJA were pain (4.6%-35%), medical concerns (5.6%-24.5%), and swelling (1.4%-17.5%). Studies analyzing the timing of ED visits found that most occurred within the first 2 weeks postdischarge. Black race and Medicaid/Medicare insurance coverage were identified as risk factors associated with ED visits. CONCLUSION ED visits present a high burden for the health care system, as upward of 1 in 10 patients will return to the ED within 90 days of TJA. Future efforts should be made to develop cost-effective and patient-centered interventions that reduce preventable ED visits after TJA. As well, these rates should be taken into consideration when allocating resources for the care of TJA patients.

Outpatient, Home-Based Physical Therapy Promotes Decreased Length of Stay and Post-Acute Resource Utilization After Total Joint Arthroplasty. J Arthroplasty 2020; 35:1968-1972. [PMID: 32340828 DOI: 10.1016/j.arth.2020.03.031] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 02/12/2020] [Accepted: 03/18/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Patients and healthcare systems are increasingly focused on evaluating interventions that increase the value of care delivered. Our objective of this study is to evaluate early post-operative outcomes among those patients who underwent total joint arthroplasty with and without the participation in our piloted Outpatient Physical Therapy Home Visits (OPTHV) program. METHODS A retrospective analysis of patients undergoing total hip arthroplasty and total knee arthroplasty at a single institution from July 2016 to September 2017 was performed. Matched cohorts were compared according to OPTHV enrollment status. RESULTS In total, 1729 patients were included in this study. Two hundred ninety-three patients were enrolled in OPTHV, while 1436 patients received institutional standard care. Patients were matched by gender (56.7% vs 57.7% female, P = .751), age (67.75 vs 66.95 years, P = .167), body mass index (30.18 vs 30.12 kg/m2, P = .859), and average American Society of Anesthesiologists score (2.31 vs 2.36, P = .131). OPTHV patients had a shorter length of stay (1.39 vs 1.64 days, P < .001) and were more likely to discharge to home (89.8% vs 74.7%, P < .001). Ninety-day re-admissions (2.7% vs 2.6%, P = .880) and emergency room visits (4.1% vs 4.3%, P = .864) were equivalent. CONCLUSION OPTHV is a novel program that facilitates discharge home and decreased length of stay after total joint arthroplasty without increasing re-admissions or emergency room visits. Utilization of OPTHV may contribute toward reducing the episode of care costs by reducing utilization of skilled nursing facility and home health services. Further prospective studies are needed to evaluate the effect of OPTHV on the total cost of care and functional outcomes.

Abstract
BACKGROUND Compared to general anesthesia (GA), neuraxial anesthesia (NA) has been associated with improved outcomes after total joint arthroplasty (TJA). We examined the impact of NA on patient outcomes in an institution with an established rapid recovery protocol. METHODS This is a single-institution retrospective analysis of 5914 consecutive primary TJA performed from July 2015 to June 2018. Univariate tests and multivariate regression compared length of stay (LOS), transfusion rates, hematocrit levels, discharge disposition, and emergency room returns between patients receiving GA and NA. RESULTS Patients receiving NA had a significantly shorter LOS (total hip arthroplasty [THA]: GA 1.74 vs NA 1.36 days, P < .001; total knee arthroplasty [TKA]: GA 1.77 vs NA 1.64 days, P < .001). Both THA and TKA patients receiving NA were less likely to require transfusion (THA: GA 5.8% vs NA 1.6%, P < .001; TKA: GA 2.5% vs NA 0.5%, P < .001) and had a higher postoperative hematocrit (THA: GA 32.50% vs NA 33.22%, P < .001; TKA GA 33.57 vs NA 34.50%, P < .001). Patients receiving NA were more likely to discharge home (THA: GA 83.4% vs NA 92.3%, P < .001; TKA: GA 83.3% vs NA 86.3%, P = .010) (THA: NA adjusted OR [aOR] 2.04, P < .001; TKA: NA aOR 1.23, P = .048) and had significantly lower rates of 90-day emergency room visits (THA: NA aOR 0.61, P = .005; TKA: NA aOR 0.74, P = .034). CONCLUSION NA appears to contribute to decreased LOS, short-term complications, and transfusions while facilitating home discharge following TKA and THA. These trends are consistent when controlling for patient-specific risk factors, suggesting NA may enhance outcomes for patients with increased age, body mass index, and comorbidities.

Temporal Trends and Predictors of Thirty-Day Readmissions and Emergency Department Visits Following Total Knee Arthroplasty in Ontario Between 2003 and 2016. J Arthroplasty 2020; 35:364-370. [PMID: 31732370 DOI: 10.1016/j.arth.2019.09.015] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 09/04/2019] [Accepted: 09/10/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Total knee arthroplasty (TKA) is the second most common surgery performed in Canada. Understanding and improving quality metrics associated with such high-volume procedures is of utmost importance to maximize value within the healthcare system, which is a balance between cost and quality. Although rates and predictors of hospital readmission and emergency department (ED) visits following TKA have previously been described in privatized healthcare settings, few studies have evaluated trends in length of stay (LOS), hospital readmissions, and ED visits following TKA in a universal single-payer system. METHODS Using data from a provincially held and validated registry, the Institute for Clinical and Evaluative Sciences, we undertook a review of all 205,152 TKAs performed in the province of Ontario, Canada, between 2003 and 2016. We determined temporal trends in utilization, LOS, readmissions, and ED visits and evaluated patient and provider predictors of hospital readmissions and ED visits using multivariate logistic regression modeling. We also grouped and described the most common reasons for readmission and ED visits based on the available International Classification of Diseases, Ninth Revision and Tenth Revision coding information. RESULTS LOS decreased significantly over the study period (P < .0001), from a median of 5 days (10th percentile 3 days, 90th percentile 8 days) in 2003 to a median of 3 days (10th percentile 2 days, 90th percentile 4 days) in 2016. All-cause 30-day readmissions did not change significantly over the study period, but the rate of ED visits increased significantly over time. Predictors of 30-day readmission following TKA included older age, male gender, lower income quartile, not having a postoperative visit with a primary care physician (PCP), increased comorbidities, longer LOS, urgent or revision surgery, admission to a teaching hospital, and discharge to an inpatient rehabilitation facility. Variables that predicted increased odds of an ED visit included older age, male gender, lower income quartile, not having a postop visit with a PCP, increasing comorbidities, year of surgery, longer LOS, and revision surgery. Admission to a teaching hospital and discharge to an inpatient rehabilitation facility showed a trend toward increased odds of an ED visit. CONCLUSIONS We identified a significant increase in ED visits following TKA in Ontario between 2003 and 2016, with no corresponding increase in hospital readmissions despite a significant temporal trend toward shorter LOS. Predictors of ED visits and readmissions were similar, including male gender, lower income, higher comorbidities, and lacking a PCP visit postoperatively. Increased rates of ED visits following TKA in Ontario represent a quality problem, as they are associated with increased cost to the public healthcare system without any substantial benefit. Interventions aimed at redirecting patients from the ED for minor postoperative concerns should be investigated, as this is likely to improve care by reducing costs, improving efficiency, and enhancing patient experience.

Modifiable, Postoperative Risk Factors for Delayed Discharge Following Total Knee Arthroplasty: The Influence of Hypotension and Opioid Use. J Arthroplasty 2020; 35:82-88. [PMID: 31500913 PMCID: PMC7194191 DOI: 10.1016/j.arth.2019.07.047] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 07/29/2019] [Accepted: 07/31/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND We sought to identify independent modifiable risk factors for delayed discharge after total knee arthroplasty (TKA) that have been previously underrepresented in the literature, particularly postoperative opioid use, postoperative laboratory abnormalities, and the frequency of hypotensive events. METHODS Data from 1033 patients undergoing TKA for primary osteoarthritis of the knee between June 2012 and August 2014 at an academic orthopedic specialty hospital were reviewed. Patient demographics, comorbidities, inpatient opioid medication, postoperative hypotensive events, and abnormalities in laboratory values, all occurring on postoperative day 0 or 1, were collected. Multivariate logistic regression analysis was performed to identify independent risk factors for a prolonged length of stay (LOS) >3 days. RESULTS The average age of patients undergoing primary TKA in our cohort was 65.9 (standard deviation, 9.1) years, and 61.7% were women. The mean LOS for all patients was 2.64 days (standard deviation, 1.14; range, 1-9). And 15.3% of patients had a LOS >3 days. On multivariate logistic regression analysis, nonmodifiable risk factors associated with a prolonged LOS included nonwhite race (odds ratio [OR], 2.01), single marital status (OR, 1.53), and increasing age (OR, 1.47). Modifiable risk factors included every 5 postoperative hypotensive events (OR, 1.31), 10-mg increases in oral morphine equivalent consumption (OR, 1.04), and postoperative laboratory abnormalities (hypocalcemia: OR, 2.15; low hemoglobin: OR, 2.63). CONCLUSION This study identifies potentially modifiable factors that are associated with increased LOS after TKA. Doubling down on efforts to control the narcotic use and to use opioid alternatives when possible will likely have efficacy in reducing LOS. Attempts should be made to correct laboratory abnormalities and to be cognizant of patient opioid use, age, and race when considering potential avenues to reduce LOS.

Characterization of Re-admission and Emergency Department Visits Within 90 Days Following Lower-Extremity Arthroplasty. HSS J 2018; 14:271-281. [PMID: 30258332 PMCID: PMC6148588 DOI: 10.1007/s11420-018-9622-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Accepted: 06/25/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Acute care events including emergency department (ED) visits and unscheduled inpatient re-admissions following lower-extremity arthroplasty are not fully understood. QUESTION/PURPOSES The purpose of this study was to characterize acute care events occurring after discharge in patients who received a lower-extremity arthroplasty: the incidence, timing, and risk factors of inpatient admission and ED visits within 90 days of discharge. METHODS The New York State Inpatient and Emergency Department Databases were used to identify patients who underwent elective total knee arthroplasty (TKA) or total hip arthroplasty (THA) from 2009 to 2013 (124,234 and 76,411 patients, respectively). Multivariate logistic regression analysis was used to determine the predictors of and the most frequent reasons for unscheduled acute care within 90 days of discharge. RESULTS Unscheduled acute care was needed in 13.79% of patients (8.81% of inpatient re-admissions and 4.98% of ED visits), most often in the first week after discharge (61.05% of all inpatient re-admissions and 20.46% of all ED visits). Most of these visits were for musculoskeletal pain, peri-prosthetic joint or wound infection, cardiac complications, blood transfusion, psychiatric events, mechanical complications, and deep vein thrombosis. Predictors for the need for acute care after TKA included African American and Hispanic race or ethnicity, Medicaid coverage, and neuraxial anesthesia. Predictors for the need for acute care after THA included older age (over 85 years), African American race, and Medicaid coverage. CONCLUSION We identified demographic and procedure-related variables associated with an increased risk of ED visits and inpatient re-admissions after TKA or THA. Understanding these variables will contribute to improved care quality.
