RESUMO
PURPOSE: Acetabular fractures are highly complex injuries often resulting from high-energy trauma. The gold standard treatment for these injuries has become open reduction internal fixation (ORIF). The purpose of this study is to further this understanding and investigate how (1) patient demographics and (2) patient-specific risk factors affect 90-day readmission rates. METHODS: A retrospective, nationwide query of private insurance database from January 1st, 2010 to October 31st, 2020 was performed using ICD-9, ICD-10, and CPT codes. Patients who underwent acetabular ORIF and were readmitted within 90 days following index procedure were included, patients who were not readmitted served as controls. Patients were divided by demographics and specific risk factors associated with readmission. RESULTS: The query yielded a total of 3942 patients. Age and sex were found to be non-significant contributing risk factors to 90-day readmissions. Data also showed that statistically significant comorbidities included arrhythmia, cerebrovascular disease, coagulopathy, fluid and electrolyte abnormalities, and pathologic weight loss. CONCLUSION: This study illustrated how several patient-specific risk factors may contribute to increased 90-day readmission risk following acetabular ORIF. A heightened awareness of these comorbidities in patients requiring acetabular ORIF is required to improve patient outcomes and minimize rates of readmission. Further investigation is needed to improve patient outcomes, and increase awareness of potential post-operative complications in these higher-risk patient populations.

PURPOSE: Antibiotic prophylaxis before invasive dental procedures is a common practice in the USA. Consensus regarding the influence of prior dental pathology (DP) on postoperative complications is lacking. The objectives are to determine the association of DP prior to shoulder arthroplasty (SA) on: (1) lengths of stay (LOS), (2) medical complications, (3) readmissions, (4) implant-related complications including peri-prosthetic joint infections (PJIs) and (5) healthcare expenditures. METHODS: The PearlDiver database was queried for primary shoulder arthroplasty from 2010 to 2020. Patients with history of dental caries or dental implant placement before SA represented the study group (n = 1419). Patients without prior DP represented controls (n = 7062). Study group patients were 1:5 ratio matched to controls by age, sex, and comorbidities. Outcomes included LOS, 90-day complications, readmissions, 2-year implant-related complications, and healthcare reimbursements. Logistic regression was used to calculate odds ratios (OR) of complications and readmissions. T tests compared LOS and costs. P values < 0.003 were significant. RESULTS: LOS (2.17 vs. 2.07 days; p = 0.071) were similar between groups. Patients with DP had higher 90-day medical complications compared to controls (OR: 1.74, p < 0.0001), including myocardial infarctions (2.2% vs. 0.8%; OR: 2.79, p < 0.0001), acute kidney injuries (8.3% vs. 4.6%; OR: 1.92, p < 0.0001), and pneumonias (8.7% vs. 5.3%; OR: 1.72, p < 0.0001). Readmission rates (1.97% vs. 1.54%; p = 0.248) were similar. Two-year implant complications were higher in patients with DP compared to controls (16.1% vs. 11.5%; OR: 1.38, p = 0.0003), including dislocations (6.4% vs. 4.5%; OR: 1.45, p = 0.002) and mechanical loosenings (4.0% vs. 2.4%; OR: 1.67, p = 0.001); however, PJIs were similar (2.2% vs. 1.9%; OR: 1.12, p = 0.583). Healthcare expenditures between groups were similar ($12,611 vs. $12,059; p = 0.075). CONCLUSION: Patients with prior DP have higher 90-day medical complications and 2-year implant-related complications. Two-year incidence of PJIs were similar between groups. These findings can help shoulder surgeons counsel patients with a pertinent dental history. LEVEL OF EVIDENCE III: Retrospective comparative study.

BACKGROUND: As the incidence and prevalence of Crohn's disease continues to change worldwide, rates within North America have been increasing. The objective of this study was to evaluate whether patients who have Crohn's disease undergoing primary total hip arthroplasties have worse outcomes compared with matched cohorts. Specifically, we evaluated 1) medical complications, 2) in-hospital lengths of stay (LOS), and 3) costs of care. METHODS: Two cohorts of patients who underwent primary total hip arthroplasties from January 1, 2005 to March 31, 2014 were identified from the Medicare claims of the PearlDiver platform. Cohorts were matched by age, sex, and following comorbidities-anemia, diabetes, hyperlipidemia, hypertension, malnutrition, pulmonary disease, and renal failure, yielding 55,361 patients within the study (n = 9229) and matching cohorts (n = 46,132). Outcomes assessed included 90-day medical complications, in-hospital LOS, and costs of care. A P-value less than .005 was considered statistically significant. RESULTS: Patients with Crohn's disease were found to have significantly higher incidences and odds ratios of 90-day medical complications (30.2 vs 13.8; odds ratios: 2.2, P < .0001). They were also found to have significantly longer LOS (3.8- vs 3.6-days, P < .0001) and higher day of surgery ($12,662.00 vs 12,271.15, P < .0001) and 90-day episode costs ($16,933.18 vs $15,670.32, P < .0001). CONCLUSION: Crohn's disease is associated with higher rates of medical complications, longer in-hospital LOS, and increased costs of care. This study may aid physicians to perform appropriate risk adjustment for adverse outcomes and to educate these patients about potential postoperative complications in these patients.

Background: A recently proposed risk factor for periprosthetic joint infections (PJI) in men is benign prostatic hyperplasia (BPH). The objective was to explore the association of BPH on 1) 90-day complications, 2) length of stay (LOS), 3) readmission rates, and 4) healthcare expenditures following total shoulder arthroplasty (TSA). Methods: A retrospective query was performed using a nationwide claims database from January 2005 to March 2014 for male patients undergoing primary TSA. The study cohort included 5067 patients with BPH while 50,720 patients served as the comparison cohort. Logistic regression determined the association of BPH on complications and readmissions. A p value less than 0.001 was significant. Results: Patients with BPH had higher incidence and odds (36.8 vs. 6.2%; OR: 2.73, p < 0.0001) of all ninety-day medical complications including PJIs (0.49 vs. 0.32%; OR: 1.54, p < 0.001). BPH patients had longer in-hospital LOS (3- vs. 2-days, p < 0.0001). Study group patients had higher 90-day episode of care reimbursements ($13,653 vs. $12,688), p < 0.0001). Conclusions: BPH is associated with increased complications and healthcare expenditures following total shoulder arthroplasty. The investigation can be used to educate BPH patients of the possible adverse events which may occur within ninety-days following primary TSA for the treatment of glenohumeral osteoarthritis.
RESUMO
OBJECTIVES: Sports medicine procedures encompass some of the highest-volume elective surgeries performed annually. Elective surgery was suspended because of the severe acute respiratory syndrome coronavirus 2 (COVID-19) pandemic; therefore, the purpose was to compare temporal trends in procedural volume, patient demographics, and postoperative complications of elective sports medicine procedures in 2019 and 2020. METHODS: Using a multicenter, nationwide sample, a retrospective query of the 2019 to 2020 American College of Surgeon's National Surgery Quality Improvement Program database was conducted for all patients undergoing common elective sports medicine procedures. Temporal trends in utilization, demographics, and 30-day complications were compared pre-COVID (2019 and 2020Q1) with post-COVID (2020Q2-Q4). Linear regression was used to evaluate changes in procedural volume over time. A significance threshold of P < 0.05 was used. RESULTS: A total of 48,803 patients underwent elective surgery in 2019 (n = 27,883) and 2020 (n = 20,920), a 25.0% decline. Procedural utilization declined by 42.5% in 2020Q2 and never returned to prepandemic baseline in 2020Q3-Q4. The percentage decline in case volume from 2019 to 2020Q2 was greatest for meniscectomy (47.6%), rotator cuff repair (42.7%), labral repair (41.6%), biceps tenodesis (41.3%), and anterior cruciate ligament reconstruction (38.5%). Total complication rates were similar in 2019 (1.31%) versus 2020 (1.51%; P = 0.072). The 30-day readmission (0.74% versus 0.67%; P = 0.374), reoperation (0.35% versus 0.35%; P = 0.963), and mortality (0.01% versus 0.01%; P = 0.657) rates were similar between calendar years. CONCLUSIONS: Sports medicine procedures declined during the second quarter of 2020. Despite pandemic restrictions, patients who did undergo surgery did not experience increased complications. The present study may be used by surgeons, hospitals, and subspecialty societies to support the careful utilization of elective surgery during COVID-19. LEVEL OF EVIDENCE: III, prognostic study.

BACKGROUND: The Elixhauser Comorbidity Index (ECI) is a stratification tool to predict adverse surgical outcomes. No studies have explored the relationship between ECI and outcomes following primary 1- to 2-level lumbar fusion (1-2LF). The purpose was to determine whether an ECI score greater than 1 correlated with (1) longer in-hospital length of stay (LOS) and (2) greater odds of developing 90-day medical complications. METHODS: A retrospective review from 2004 to 2015 was performed using the Medicare Standard Analytical Files for patients undergoing primary LF. Patients with ECI scores from 2 to 5 served as the study cohorts (1 for each ECI score), and patients with an ECI score of 1 served as the control cohort. In-hospital LOS and 90-day medical complications were compared between cohorts. A P value of <0.001 was statistically significant. RESULTS: A total of 105,120 patients were equally distributed between the 5 cohorts. Patients with an ECI score of 2 (6.00 ± 4.51), ECI 3 (6.22 ± 4.67), ECI 4 (7.35 ± 5.05), or ECI 5 (8.99 ± 5.67) had longer in-hospital LOS compared with patients with an ECI score of 1 (4.28 ± 4.36) (all P < 0.001). Patients with an ECI score of 2 (OR: 1.17, 95% CI: 1.05-1.30, P = 0.003; 2.85% vs 2.45%), ECI 3 (OR: 1.22, 95% CI: 1.10-1.36, P < 0.001; 2.98% vs 2.45%), ECI 4 (OR: 1.26, 95% CI: 1.13-1.40, P < 0.001; 3.10% vs 2.45%), or ECI 5 (OR: 1.18, 95% CI: 1.06-1.31, P = 0.001; 2.89% vs 2.45%) had greater incidence and odds of 90-day medical complications such as pneumonia, deep vein thrombosis, cerebrovascular accidents, and myocardial infarctions than patients in the control group (all P < 0.0001). CONCLUSIONS: Increasing ECI score was associated with longer in-hospital LOS and increased 90-day medical complication rates following 1-2LF. This study is the first to establish a correlation between ECI score, in-hospital LOS, and complication rates following lumbar fusion. CLINICAL RELEVANCE: ECI score may assist physicians in adjusting pre- and postoperative care for complex patients undergoing 1-2LF.
RESUMO
INTRODUCTION: Complication rates are used to evaluate surgical quality-of-care and determine health care reimbursements. The U.S. News & World Report (USNWR) hospital rankings are a highly-referenced source for top hospitals. The objective of this study was to determine the surgeon demographics of those practicing at USNWR Top Ranked Orthopedic Hospitals and if any influence complication rates after total knee arthroplasty (TKA). METHODS: The 2009-2013 USNWR 'Orthopedic' hospital rankings were identified. A database of TKA surgeons with postoperative complication rates was compiled utilizing publicly available data from the Centers for Medicare and Medicaid Services (2009-2013). Using an internet search algorithm, demographic data were collected for each surgeon and consisted of: fellowship training, years in practice, age, gender, practice setting, medical degree type, residency reputation, case volume, and geographic region of hospital. Logistic regression was used to assess the relationship between surgeon demographics and postoperative complication rates. A P value of < 0.008 was considered significant. RESULTS: From 2009 to 2013, 660 orthopedic surgeons performed TKA at 80 different USNWR Top-Ranked Hospitals. Mean TKA case volume was 172 (Range, 20-1323) and age of surgeon was 50.8 (Range, 32-77). A total of 372 (56.8%) completed an orthopedic surgery fellowship. Mean adjusted 30-day complication rate was 2.24% (Range, 1.2-4.5%). After adjustment, factors associated with increased complication rates were surgeon age ≤ 42 (OR 3.15; P = 0.007) and lower case volume (≤ 100 cases) (OR 2.52; P < 0.0001). Gender, hospital geographic region, completion of a fellowship, medical degree type, and residency reputation were not significant factors. DISCUSSION: Complication rates of total knee arthroplasty surgeons may be utilized by patients and hospitals to gauge quality of care. Certain surgeon factors may influence complication rates of surgeons performing TKA at USNWR Top Ranked Orthopedic Hospitals. STUDY TYPE: Level III, retrospective observational study.
RESUMO
Introduction: Readmissions following orthopaedic surgery are associated with worse outcomes and increased healthcare costs. Studies investigating trends, causes, and costs of readmissions following primary total shoulder arthroplasty (TSA) for the indication of glenohumeral osteoarthritis (OA) are limited. The objective was to compare: 1) patient-demographics of those readmitted and not readmitted within 90-days following primary TSA for OA; 2) causes of readmissions and 3) associated costs. Methods: A retrospective query from 2005 to 2014 was performed using a nationwide administrative claims database. The study group consisted of patients readmitted within 90-days following primary TSA for glenohumeral OA, whereas patients not readmitted served as controls. Causes of readmission were stratified into the following groups: cardiovascular, hematological, endocrine, gastrointestinal (GI), musculoskeletal (MSK), neoplastic, neurological, pulmonary, infectious, renal, and miscellaneous causes. Patient demographics were compared, in addition to the frequency of the causes of readmissions, and their associated costs. Chi-square analyses compared demographics between groups. Analysis of variance was utilized to determine differences in 90-day costs for the causes of readmission. A p-value less than 0.001 was significant. Results: The overall 90-day readmission rate was 2.4% (3432/143,878). Patients readmitted following primary TSA were more likely to be over the age of 75, female, and higher prevalence of comorbid conditions, including psychiatric and medical conditions. Readmitted patients had a higher overall comorbidity burden per mean Elixhauser-Comorbidity Index (ECI) scores (10 vs. 7,p < .0001). The leading cause of readmissions were due to MSK (17.34%), cardiac (16.28%), infectious (16.26%), and gastrointestinal (11.64%) etiologies. There were differences in the mean 90-day costs of care for the various causes of readmissions, with the leading cost of readmissions being cardiac causes ($10,913.70) and MSK ($10,590.50) etiologies. Conclusion: Patients with greater comorbidities experienced increased incidence of readmission following TSA for glenohumeral OA. Cardiac and MSK etiologies were the primary cause of readmissions. Level of evidence: III.
RESUMO
PURPOSE: Alcohol use disorder is a leading mental health disorder in the United States. Few studies evaluating the association of alcohol use disorder following primary total hip arthroplasty (THA) have been reported. Therefore, the purpose of this study was to determine whether patients with alcohol use disorder undergoing primary THA have higher rates of: 1) in-hospital lengths of stay (LOS); 2) complications (medical/implant-related); and 3) costs. MATERIALS AND METHODS: Using a nationwide claims database from January 1st, 2005 to March 31st, 2014, patients with alcohol use disorder undergoing primary THA were identified and matched to a comparison group according to age, sex, and various comorbidities, resulting in 230,467 patients who were included in the study (n=38,416) and a matched-cohort (n=192,051). Outcomes of interest included comparison of LOS, 90-day medical and 2-year implant-related complications, and costs. A P-value less than 0.002 was considered statistically significant. RESULTS: Patients with alcohol use disorder had longer in-hospital LOS (4 days vs 3 days; P<0.0001) as well as higher frequency and odds ratio (OR) of 90-day medical (45.94% vs 12.25%; OR, 2.89; P<0.0001) and 2-year implant-related complications (17.71% vs 8.46%; OR, 1.97; P<0.0001). Patients in the study group incurred higher 90-day costs of care ($17,492.63 vs $14,921.88; P<0.0001). CONCLUSION: With the growing prevalence of alcohol use disorder in the United States, the current investigation can be utilized to evaluate the need for interventions prior to THA which can potentially minimize the rates of morbidity and mortality within this population.
RESUMO
PURPOSE: The purpose of this study was to evaluate whether patients undergoing primary total hip arthroplasty (THA) at a higher elevation have higher rates of: 1) in-hospital length of stay (LOS); 2) surgical site infections (SSIs); 3) periprosthetic joint infections (PJIs); and 4) costs. MATERIALS AND METHODS: The Medicare claims database was used to identify patients who underwent primary THA at an altitude higher than 4,000 feet (ft). High-altitude patients were matched to patients who underwent primary THA at an altitude less than 100 ft, yielding 24,958 and 124,765 patients respectively. Outcomes that were assessed included in-hospital LOS, SSIs, PJIs, and costs of care. A P-value less than 0.001 was considered statistically significant. RESULTS: Patients in the study group had significantly longer in-hospital LOS (4 days vs 3 days, P<0.0001). In addition, patients in the study group had a significantly higher incidence and odds of developing SSIs (1.16% vs 0.86%; odds ratio [OR], 1.34; P<0.0001) and PJIs (0.91% vs 0.58%; OR, 1.56; P<0.0001) within 90-days following the index procedure, compared to matched controls. Higher altitude patients incurred higher day of surgery ($16,139.76 vs $15,279.42; P<0.0001) and 90-day costs ($18,647.51 vs $16,401.62; P<0.0001). CONCLUSION: This study demonstrated that primary THA procedures performed at an elevation higher than 4,000 ft are associated with longer in-hospital LOS, higher rates of SSIs, PJIs, and costs of care. Orthopedists and other healthcare professionals can use this information to provide adequate education for these patients regarding the potential complications that may occur following their procedure.
