[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.

[PMID: 37356460 DOI: 10.1016/j.spinee.2023.06.384] [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: 08/18/2022] [Revised: 05/19/2023] [Accepted: 06/12/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND CONTEXT Lumbar discectomy is a common procedure following which emergency department (ED) visits may occur. Although many quality improvement initiatives target reemissions, ED visits may be more common, be a marker of quality of care, affect patient satisfaction, and contribute to health-care resource utilization and costs. PURPOSE To analyze the timing and risk factors predicting ED utilization following lumbar discectomy and thereby facilitate better-targeted risk reduction. STUDY DESIGN/SETTING Retrospective database review of the 2010 to April 30th, 2021, M157Ortho PearlDiver dataset. PATIENT SAMPLE Single-level lumbar laminotomy/discectomy between 2010 and April 30th, 2021, in the PearlDiver M157Ortho dataset. OUTCOME MEASURES Functional measures-ED utilization in the 90 days following lumbar discectomy, patient-level predictors for ED utilization, and number and type of reoperations performed in the 90 days following lumbar discectomy. METHODS Lumbar laminotomies/discectomies were identified. Patients were excluded if additional procedures were performed or if there was not 90-day follow-up in the dataset. Patient factors were extracted, including age, sex, Elixhauser comorbidity index (ECI), region of the country in which their procedure was performed (Midwest, Northeast, South, West), and patient insurance plan (Commercial, Medicaid, Medicare). The incidence, timing, and frequency of ED utilization within 90 days of lumbar discectomy were then determined. Cohort average weekly ED utilization at 1-year postoperatively was calculated as a baseline for reference. Patient factors predictive of postoperative ED utilization were then determined with univariate and multivariate analyses. Primary diagnoses for ED visits were also categorized. Patients who underwent reoperation for complications related to lumbar discectomy following ED visits were determined, and types of reoperation procedures were characterized. RESULTS Of 281,103 lumbar discectomy patients identified, ED visits within 90 days of surgery were identified for 28,632 (10.2%). Of note, 40.4% of these ED visits occurred in the first 2 postoperative weeks. Multivariate analysis revealed several independent predictors of ED utilization following lumbar discectomy, including: younger age (odds ratio [OR] 1.21 per decade decrease), female sex (OR 1.12 relative to male), higher ECI (OR 1.42 per 2-point increase), having surgery performed in the Northeast, Midwest, or West United States (OR 1.05, 1.17, and 1.13, respectively, relative to South), and Medicaid coverage (OR 1.89 relative to Medicare). Forty-three percent of ED visits were surgical site related, of which surgical site pain predominated at 34.2% of overall reasons. Of patients who visited the ED, 943 (3.3%) underwent reoperation in the subsequent 2 weeks. Laminectomy with nerve root decompression was the most performed reoperation (30.9%), followed by incision and drainage (22.5%), posterior nonsegmental instrumentation (10.3%), laminectomy facetectomy and foraminotomy (9.97%), repair of dural/CSF leak or pseudomeningocele with laminectomy (9.3%), repair of dural/CSF leak not requiring laminectomy (8.9%), arthrodesis (4.3%), and posterior segmental instrumentation (3.9%). CONCLUSIONS Following lumbar discectomy, over 1 in 10 patients were found to visit the ED in the 90 days following their surgery, most commonly in the first 2 postoperative weeks. Specific patient characteristics were associated with such ED visits, with the most common primary diagnoses among ED visitors being surgical site pain. About 3.3% of patients who visited the ED underwent reoperation in the subsequent 2 weeks. Through identification of the timing, risk factors, primary reasons for, and risk of reoperation following ED utilization in the 90-day period after lumbar discectomy, care pathways can be modified to improve patient satisfaction, outcomes, and reduce excess health-care expenditures.

Ninety-Day Emergency Department Visits After Ankle Fracture Surgery. J Am Acad Orthop Surg 2023; 31:e51-e57. [PMID: 36548157 DOI: 10.5435/jaaos-d-22-00484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Accepted: 09/04/2022] [Indexed: 12/24/2022] Open
Abstract
INTRODUCTION Emergency department (ED) visits after orthopaedic procedures such as ankle fracture open reduction and internal fixation (ORIF) have received less attention than other outcomes. This study analyzed 90-day ED visits after ankle fracture surgery in a national database to better characterize the incidence, timing, risk factors, and reasons. METHODS Ankle fractures undergoing ORIF were extracted from the PearlDiver M91Ortho 2010 to 2020Q3 data set. Patients were excluded for age younger than 18 years, presence of concomitant fractures, and <90 days of database follow-up. Patient age, sex, Elixhauser Comorbidity Index score, region of the country, and insurance plan were analyzed as predictors for 90-day ED utilization using multivariate logistic regression. Incidence of readmissions and incidence, timing, risk factors, and reasons for ED visits were determined. RESULTS Of 87,662 ankle fracture ORIF patients identified, ED visits were noted within 90 days of surgery for 10,087 (11.5%) while 4,030 (4.6%) were readmitted. One ED visit was noted for 6,102 patients, two visits for 2,654, three visits for 787, and more than three visits for 544. The greatest weekly incidence of ED visits was observed in weeks 1 and 2, with 2.9% and 3.1% of the entire cohort visiting in each week respectively. Factors independently associated with 90-day ED utilization included younger age (odds ratio [OR] 1.21 per decade decrease, P < 0.001), greater Elixhauser Comorbidity Index score (OR 1.40 per two-point increase, P < 0.001), and Medicaid insurance (OR 1.92, P < 0.001). In the first two postoperative weeks, 71% of ED visits were attributed to issues directly involving the surgical site while in subsequent weeks, most visits did not involve the surgical site (65%). DISCUSSION Many patients visit the ED after ankle fracture surgery. The greatest ED utilization was during the first two postoperative weeks, and reasons for visits were defined. These findings have implications for optimizing care pathways and targeting resource allocation.

Abstract
Background Total ankle replacement (TAR) utilization in the United States has steeply increased in recent decades. Emergency department (ED) visits following TAR impacts patient satisfaction and health care costs and warrant exploration. Methods This retrospective cohort study utilized the 2010 to 2019 M91Ortho PearlDiver data set to identify TAR patients with at least 90 days of follow-up. PearlDiver contains billing claims data across all sites of care throughout the United States for all indications for care. Patient factors extracted included age, sex, Elixhauser Comorbidity Index (ECI), region of the country in which surgery was performed, insurance plan, and postoperative hospital length of stay. Ninety-day postoperative ED visit incidence, timing, frequency, and primary diagnoses were identified and compared to 1-year postoperative ED visit baseline data. Univariate and multivariate logistic regression analyses were used to determine risk factors for ED visits. Results Of 5930 TAR patients identified, ED visits within 90 days were noted for 497 (8.4%) patients. Of all ED visits, 32.0% occurred within 2 weeks following surgery. Multivariate analysis revealed several predictors of ED utilization: younger age (odds ratio [OR] 1.35 per decade decrease), female sex (OR 1.20), higher ECI (OR 1.32 per 2-point increase), TAR performed in the western US (OR 1.34), and Medicaid coverage (OR 2.70; 1.71-4.22 relative to Medicare) (P < .05 each). Surgical site issues comprised 78.0% of ED visits, with surgical site pain (57.0%) as the most common problem. Conclusion Of 5930 TAR patients, 8.4% returned to the ED within 90 days of surgery, with predisposing demographic factors identified. The highest incidence of ED visits was in the first 2 postoperative weeks, and surgical site pain was the most common reason. Pain management pathways following TAR should be able to be adjusted to minimize the occurrence of postoperative ED visits, thereby improving patient experiences and decreasing health care utilization/costs.

Unplanned Emergency and Urgent Care Visits After Outpatient Orthopaedic Surgery. JOURNAL OF THE AMERICAN ACADEMY OF ORTHOPAEDIC SURGEONS GLOBAL RESEARCH AND REVIEWS 2021; 5:01979360-202109000-00012. [PMID: 34543235 PMCID: PMC8454905 DOI: 10.5435/jaaosglobal-d-21-00209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 08/29/2021] [Indexed: 11/30/2022]
Abstract
Introduction This study sought to determine (1) incident risk, (2) chief report, (3) risk factors, and (4) total cost of unplanned healthcare visits to an emergency and/or urgent care (ED/UC) facility within 30 days of an outpatient orthopaedic procedure. Methods This was a retrospective database review of 5,550 outpatient surgical encounters from a large metropolitan healthcare system between 2012 and 2016. Statistical analysis consisted of measuring the ED/UC incident risk, respective to the procedures and anatomical region. Patient-specific risk factors were evaluated through multigroup comparative statistics. Results Of the 5,550 study patients, 297 (5.4%) presented to an ED/UC within 30 days of their index procedure, with 23 (0.4%) needing to be readmitted. Native English speakers, patients older than 45 years, and nonsmokers had significant reduced relative risk of unplanned ED or UC visit within 30 days of index procedure (P < 0.01). In addition, hand tendon repair/graft had the greatest risk incidence for ED/UC visit (11.0%). Unplanned ED/UC reimbursements totaled $146,357.34, averaging $575.65 per visit. Discussion This study provides an evaluation of outpatient orthopaedic procedures and their relationship to ED/UC visits. Specifically, this study identifies patient-related and procedural-related attributes that associate with an increased risk for unplanned healthcare utilization.

Risk Factors for Short-Term Complication After Open Reduction and Internal Fixation of Ankle Fractures: Analysis of a Large Insurance Claims Database. J Foot Ankle Surg 2021; 59:239-245. [PMID: 32130984 DOI: 10.1053/j.jfas.2019.08.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Revised: 08/06/2019] [Accepted: 08/11/2019] [Indexed: 02/03/2023]
Abstract
Although fractures of the ankle are common injuries treated by surgical podiatrists and orthopaedic surgeons specializing in foot and ankle surgery, postoperative complications can occur, often imposing an economic burden on the patient. As health care in the United States moves toward value-based care, cost reduction has primarily focused on reducing complications and unplanned episodes of care. We used a large modern database of insurance claims to examine patterns of complications after open reduction internal fixation of ankle fractures, identifying diabetes mellitus and history of myocardial infarction as risk factors for postoperative infection within 30 days of surgery. Lateral malleolar repair was less likely to lead to infection, or need for repeated surgery, than was medial malleolar fracture repair. Diabetes mellitus, neuropathy, and chronic obstructive pulmonary disease were associated with development of postoperative cellulitis. Patients with a history of cerebrovascular accident were more likely to return to the emergency department or to have a pulmonary embolism. Male sex, presence of lupus, and increased age were associated with repeat surgery.

Factors affecting emergency department visits, readmissions, and reoperations within 30 days of ankle fracture surgery- an institutional retrospective study. Injury 2020; 51:2698-2702. [PMID: 32718753 DOI: 10.1016/j.injury.2020.07.044] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 07/08/2020] [Accepted: 07/20/2020] [Indexed: 02/02/2023]
Abstract
INTRODUCTION With the U.S. healthcare system focused on value of care, providers and hospitals are increasingly measured by factors that increase patient care and decrease healthcare cost. Early postoperative adverse events not only increase healthcare cost, but also illuminate areas of potential improvement in patient care. This large single institution study aims to delineate factors that may influence emergency department visits, admissions, and reoperations within 30 days of ankle fracture surgery. METHODS This retrospective review of patients at a Level 1 trauma center evaluated 30-day outcomes after ankle fracture surgery over a 4-year period (2015-2018). A total of 596 patients were included in final analysis. The primary outcome measures assessed were emergency department (ED) visits within 30 days, unplanned readmissions within 30 days and unplanned return to the operating room (OR) within 30 days. Patient and injury characteristics were investigated as potential factors related to these 30-day outcomes. Multiple linear regression was used for outcomes. RESULTS Forty-three (7.2%) patients visited the ED within thirty days, 30 (5.0%) patients were readmitted within thirty days, and 10 (1.7%) patients requiring reoperation within thirty days. Sex, insurance status, several comorbidities, smoking status, and fracture type/location were not found to be significantly related to 30-day events. Age less than 45 was a significant risk factor for returning to the ED within 30 days (RR 2.1, p = 0.016). Open fractures were more likely to require unplanned reoperation than closed fractures (RR 5.7, p<0.01). Fifty-four percent of ED visits were for postoperative pain, while 37% of ED visits and 60% of readmissions within 30 days were for issues unrelated to the ankle fracture. CONCLUSIONS Age less than 45 years old was a risk factor for early ED visits, highlighting a potential "at-risk" population after ankle fracture surgery. Furthermore, many of the ED visits (37%) and readmissions (60%) were unrelated to the ankle fracture suggesting unnecessary healthcare utilization may be avoided with protocols that increase emphasis on reconditioning and optimization of comorbidities.

Abstract
Purpose The recent outbreak of the novel coronavirus (SARS-CoV-2) has emphasised the need to minimise hospital admissions and utilisation of healthcare resources. The purpose of this study was to examine the outcomes of an outpatient surgery protocol for acute closed ankle fractures. Methods In this retrospective study, 262 patients underwent outpatient surgery for their closed ankle fractures at our level-1 trauma centre. A total of 196 patients met our inclusion criteria and were ultimately included in the final analysis. Our primary outcomes’ measures included post-operative admission to the emergency department within 30 days after surgery and unplanned hospital readmission within 30 days after surgery. Our secondary outcome measure included the incidence of surgical site infection (SSI) within 12 weeks after surgery. Results Thirty-two patients (16.3%) had an unplanned emergency department visit within 30 days of fracture fixation and two patients (1.0%) required hospital readmission within 30 days of their surgery. Sixteen patients (8.2%) developed SSI, which included 11 (5.6%) superficial and five (2.6%) deep infections. Conclusion Strategic outpatient management of acute closed ankle fractures is associated with acceptable rates of unplanned emergency department visits, hospital readmissions, and SSIs. In the context of the recent SARS-CoV-2 outbreak, outpatient management of these injuries may aide in the mitigation of nosocomial infections and the preservation of finite healthcare resources.

Abstract
There has been an increase in the number of hip arthroscopy procedures performed in the outpatient setting. The purpose of this study was to query a national database to compare post-operative adverse events between hip arthroscopy procedures performed in hospital based outpatient departments (HOPD) versus ASC's. The Humana Claims Database was queried for all patients undergoing hip arthroscopy performed between 2007 and 2016, using the PearlDiver supercomputer. The study population was divided into two cohorts based on the surgical setting, ASC or HOPD. Complications of interest occurring within 90 days after surgery included Center for Medicare and Medicaid Services (CMS)-reportable complications, readmission, and return to the operating room. Visits to the emergency department after 7 days of surgery was also studied. Univariate comparisons between ASC and HOPD groups were drawn with chi-square tests for categorical variables and t-tests for continuous variables. Logistic regression models were created to determine the association between surgical setting and primary outcomes. Rates of 90-day CMS-reportable complications (2.95% vs 2.17%%; p = 0.193), 90-day readmission (4.95% vs 4.25%; p = 0.370) and return to the operating room within 90 days (0.07% vs 0.2%; p = 0.286) were not significantly different between groups. Rate of visits to the emergency department within 7 days was not statistically different between groups (2.57% vs 3.03%; p = 0.458). With the ASC group as reference, no statistically significant association between an outcome and surgical setting was detected after adjusting for confounding factors including comorbidity burden. These findings provide reassurance to providers who perform these procedures in either surgical setting.
