Orthopedic surgery residents reported increased shoulder procedure volumes during the COVID-19 pandemic

The purpose of this study is to evaluate the impact of the COVID-19 pandemic on shoulder procedure volumes reported to the Accreditation Council for Graduate Medical Education by orthopedic surgery residents. We performed a retrospective review of Accreditation Council for Graduate Medical Education case logs reporting data from graduating orthopedic surgery residents during the academic years of 2006-2022. Data were queried for all patients for the following shoulder Current Procedural Terminology codes: incision, excision, intro or removal, repair/revision/reconstruction, fracture and/or dislocation, manipulation, arthroscopy, trauma, and total procedures performed. Individual t-tests were used to compare case log trends of graduating academic years before (classes of 2018 and 2019) and during (classes of 2020, 2021, and 2022) the COVID-19 pandemic. Statistical significance was established to be P <.05 for total procedure types, but at P <.005 during category comparisons to protect against alpha errors. Reported mean total shoulder procedures per resident steadily increased each year from 2017 to 2022, but the only significant increase was seen when comparing the graduating classes of 2020 to 2021 (157.9 vs. 165.7, P=.02). Stratification of these procedures by subgroup revealed a significant increase in manipulation procedures from 2021 to 2022 (7.3 vs. 8.8, P=.001). COVID-19 did not have a negative impact on logged shoulder procedure volume. Orthopedic surgery residents graduating during the COVID-19 pandemic reported more shoulder procedures than those graduating prepandemic. However, shoulder procedure log trends should be longitudinally investigated, as preceding years of procedural opportunities may underestimate the pandemic's impact.

The Effect of Surgeon Volume on Revision for Periprosthetic Joint Infection: An Analysis of 602,919 Primary Total Knee Arthroplasties.

Periprosthetic joint infection (PJI) is a devastating complication of total knee arthroplasty (TKA). An association between low surgeon volume and higher rates of infection following primary TKA has been suggested. The purpose of the present study was to determine if there was a relationship between surgeon volume and the rate of revision for infection after primary TKA. We searched the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) to identify all primary TKA procedures that were performed for the treatment of osteoarthritis from September 1, 1999, to December 31, 2020, and were subsequently revised because of infection. Surgeon volume was defined as the annual volume of procedures performed by a surgeon during the same year in which the primary TKA (which was subsequently revised for infection) was performed. Surgeon volume was defined as <25, 25 to 49, 50 to 74, 75 to 99, or ≥100 primary TKA procedures/year. The cumulative percent revision (CPR) for infection was determined with use of Kaplan-Meier estimates. Cox proportional hazards methods were used to compare rates of revision for infection by surgeon volume, with subanalyses for patellar resurfacing and polyethylene use. Further analyses for patients <65 years of age and male patients were undertaken. Overall, 602,919 primary TKA procedures were performed for the treatment of osteoarthritis, of which 5,295 were revised because of infection. High-volume surgeons (≥100 TKAs/year) had a significantly lower rate of revision for infection, with a CPR at 1 and 19 years of 0.4% (95% confidence interval [CI], 0.3 to 0.4) and 1.5% (95% CI, 1.2 to 2.0), respectively, compared with 0.6% (95% CI, 0.5 to 0.7) and 2.1% (95% CI, 1.8 to 2.3), respectively, for low-volume surgeons (<25 TKAs/year). Hazard ratios (HRs), adjusted for age and sex, comparing these 2 groups varied, depending on the time point, between 3.07 (95% CI, 2.02 to 4.68) and 1.44 (95% CI, 1.26 to 1.63) but remained significant (p < 0.001). When the analysis was adjusted for age, sex, American Society of Anesthesiologists (ASA) classification, and body mass index (BMI), there remained an increased risk of revision for PJI for all lower surgeon volume levels in comparison with the high- surgeon-volume group (≥100 TKAs/year). The results were similar when stratified by patellar resurfacing and cross-linked polyethylene (XLPE) and adjusted for age and sex. High-volume surgeons had lower rates of revision for infection. A better understanding of how surgical volume contributes to decreasing this complication is important and requires in-depth study. Prognostic Level III .

Impact of the COVID-19 pandemic on oral health care use in the United States through December 2021

BackgroundThe purpose of this study was to assess the effects of the COVID-19 pandemic on oral health care provided from July 2020 through December 2021 using national claims data. MethodsDeidentified quarterly claims from 2017 through 2021 were analyzed (2017-2019 provided prepandemic data). Data were sorted into multiple treatment categories. Analyses compared prepandemic with postpandemic procedure volumes and were stratified according to age groups (0-5 years, 6-18 years, 19-64 years, ≥ 65 years). ResultsFor children aged 0 through 5 years, use of sealants and topical fluorides other than varnish were considerably lower in 2021, as were direct operative and palliative procedures from 2020 through 2021. Only use of silver diamine fluoride, prefabricated crowns, and oral surgery increased significantly (P < .05) in some quarters. For children aged 6 through 18 years, diagnostic, direct operative, periodontic, oral surgery, and palliative procedures were significantly lower in most of 2020 through 2021, and only prefabricated crowns and indirect operative procedures increased significantly in more than 3 quarters. For adults aged 19 through 64 years, diagnostic and preventive procedures were significantly lower in 3 quarters, and direct operative, gingival surgery, endodontic, and palliative procedures were significantly lower in most of 2020 through 2021. Only occlusal guards and scaling and root planing increased significantly in more than 3 quarters. For adults 65 years and older, direct operative, gingival and osseous surgery, and palliative procedures were significantly lower in more than 3 quarters; all other procedures increased significantly in more than 3 quarters. ConclusionsThe pandemic was associated with changes in the provision of oral health care that persisted for more than 1 year. Practical ImplicationsReductions in preventive procedure volumes across age groups younger than 65 years may have implications for longer-term effects of the pandemic.

Common postbariatric surgery emergencies for the acute care surgeon: What you need to know.

The field of bariatric and metabolic surgery has changed rapidly over the past two decades, with an exponential increase in case volumes being performed because of its proven efficacy for morbid obesity and obesity-related comorbidities. Although this increased volume of procedures has been accompanied by significant decrease in postoperative complication rates, there are numerous potential complications after bariatric surgery that may require urgent or emergent surgical evaluation or interventions. Many of these risks extend well beyond the early postoperative period and can present months to years after the index procedure. Acute care surgeons are increasingly covering most or all of the emergency general surgery services at many centers and must be familiar with the numerous bariatric surgical procedures being performed and their individual complication profile to provide optimal care for these frequently challenging patients. This article provides a focused and concise review of the common bariatric procedures being performed, their early and late complication profiles, and a practical guide to the optimal diagnostic evaluations, surgical interventions, and perioperative management options. The author group includes both acute care surgeons and bariatric surgeons with significant experience in the emergency management of the complicated postbariatric surgical patient.

Device use trends in neuroendovascular procedures in the United States from 2015 to 2020.

Neuroendovascular therapies involve an everchanging landscape of new technologies. Understanding the real-world timeframe of adaptation of such technologies can provide further guidance on mechanisms that could be employed to shorten the duration necessary for the widespread use of proven therapies. In this study, we aim to investigate the trends in the use of neuroendovascular technologies, utilizing the sales of neuroendovascular devices, as a proxy for procedural volume. Utilizing a device sales data registry from the Decision Resources Group, a healthcare research and consulting company, we examined trends in the sales of devices utilized in cerebrovascular thrombectomy, cerebral aneurysm treatment, and carotid stenting from the same 407 reporting hospitals in the United States between January 1, 2015, and January 1, 2020. Device sales per year were plotted as both the total number of devices sold per year as well as the percent of total device sales when compared against at least one other device. The Cochran-Armitage test for trend was performed when comparing at least two devices to each other. Analyses were performed using RStudio Version 1.1.456 (https://rstudio.com). Between 2015 and 2020, there was a significant increase in the use of flow-diverting stents as well as nondiverting stents utilized for coil assistance. However, the total number of coils utilized over the years has declined. In terms of stroke therapy, between 2015 and 2020, there was a trend of increased use of both aspiration catheters as well as stent retrievers, which plateaued in 2020. The number of stents used for carotid procedures has also been gradually increasing over time. Our study demonstrates an increase in the use of flow-diverting stents, nondiverting stents, carotid stents, and reperfusion devices for acute ischemic stroke intervention between 2015 and 2020. Coil use for aneurysmal treatment has declined.

A comparison of financial and operational efficiency between smart and traditional insufflation for laparoscopic surgery: A granular analysis

ObjectiveSmart insufflation (SI) techniques relying on valve and membrane-free insufflation are increasing in usage. Although considerable literature exists demonstrating the benefits of SI on procedural ease and patient outcomes, there remains a paucity describing the financial impact of these devices. The purpose of this study was to determine the financial and efficiency impact of these devices on the operating room and inpatient wards of a hospital. MethodsA discrete event simulation model representing a typical mid-sized North American hospital comparing SI to traditional insufflation (TI) was generated. The National Surgical Quality Improvement database from 2015 to 2019 was used to populate the model with data supplemented from the literature. Outcomes included length of stay (LOS), duration of surgery (DOS), annual procedure volume, profit, return on investment (ROI), and gross profit margin (GPM). From the literature review, DOS savings were 10–32 minutes/case, while LOS savings were 0–3 days/case. ResultsImplementation of an SI led to an increase in annual throughput of 42–346 (4.4%–36.6%) cases for all procedures and 38 to 297 (4.3%–33.3%) cases for complex procedures. LOS was found to be decreased by 175–614 (18.3%–64.2%) days for all procedures and 231 to 614 (35.6%–77.9%) cases for complex procedures with the implementation of an SI. Together, this resulted in an increase in net profit of $104,685 per annum. The ROI of SI over the TI device was >1000%, and the GPM for the TI was 90.0%, while the GPM for the SI was 71.7%. ConclusionDespite the initial financial investment being greater, the implementation of SI offsets these expenses and yields significant financial benefits. Our study demonstrates the financial benefits of SI over TI and illustrates how granular operational and financial analyses of technologies are essential to aid in sound healthcare procurement decision making.

Impact of Center Procedural Volume on Mortality and Readmission Rates Following Pericardiectomy in the United States

Our study aimed to explore the national trends in the rates of perioperative complications, in-hospital mortality, and readmissions after pericardiectomy and the impact of center volume on these outcomes. Using the Nationwide Readmission Database, we identified patients who underwent isolated pericardiectomy from 2010 to 2019. In-hospital mortality and readmission rates were assessed using orthogonal polynomial contrasts, with the linear and nonlinear trends evaluated as needed. Multivariable logistic regression models were constructed to identify the independent predictors of mortality and readmission. All analyses accounted for the Nationwide Readmission Database sampling design and were performed using SAS version 9.4 (SAS Institute Inc. Cary, NC.) with p <0.05 used to indicate statistical significance. A total of 26,169 hospitalizations for pericardiectomy were identified during the study period. The median age was 59years and 44% were female. In-hospital mortality was 5.2%, and the median length of stay was 7days. Advanced age, higher co-morbidity index, and lower annual facility pericardiectomy volume were independent predictors of in-hospital mortality. The 30- and 90-day readmission rates after pericardiectomy were 18% and 28%, respectively. Previous cardiac surgery, diagnosis of constrictive pericarditis, and greater co-morbidity score were independent predictors of readmission. In conclusion, isolated pericardiectomy rates have remained mostly constant, with relatively small changes in in-hospital mortality and 30- and 90-day readmission rates over the last decade. Advanced age, lower facility pericardiectomy volume, and higher Elixhauser co-morbidity index are independent predictors of surgical mortality.

Patterns of Aortic Valve Replacement in Europe: Adoption by Age

Introduction: The management of patients with severe aortic stenosis may differ according to patients’ age. The aim of this analysis was to describe patterns of aortic valve replacement (AVR) use in European countries stratified by age. Methods: Procedure volume data for AVR, including surgical aortic valve replacement (sAVR) and transcatheter aortic valve implantation (TAVI), for the years 2015–2020 were obtained from national databases for twelve European countries (Austria, the Czech Republic, Denmark, England, Finland, France, Germany, Norway, Poland, Spain, Sweden, and Switzerland). Procedure volumes were reported by patient age (<50 years, 5-year age groups between 50 and 85 years, and ≥85 years). Patients per million (PPM) population undergoing AVR each year were calculated using population estimates from Eurostat. Results: AVR PPM varied widely between countries, from 508 PPM in Germany to 174 PPM in Poland in 2020. TAVI rates ranged from 61% in Switzerland and Finland to 25% in Poland. AVR PPM increased with age to a peak at 80–84 years, after which it decreased again. AVR procedures increased from 2015 to 2019 at an average annual rate of 3.9%. AVR increased more substantially in people aged ≥80 years than in younger age groups; these older age groups accounted for 30% of all AVR procedures in 2015 and 35% in 2019. TAVI accounted for an increasing proportion of all AVR procedures as patient age increased; an overall average of 96% of males and 98% of females aged ≥85 years received TAVI as the treatment modality, although adoption of TAVI differed between countries. Conclusions: There is considerable variation in the rates of AVR use and the adoption of TAVI versus sAVR between European countries. The use of TAVI has increased in recent years, particularly for older patients.

Gastrointestinal hospitalization during COVID-19 pandemic in the United States: Analysis of a nationwide inpatient sample.

We aim to systematically investigate gastrointestinal (GI) hospitalizations in the United States during the early phase of the COVID-19 pandemic on a national level and the consequence that may inform practice and policies. A retrospective cross-sectional analysis of adult hospitalizations with GI-related diagnoses or procedures in the United States in 2020 was used, with hospitalizations from 2016 to 2019 used for contextual information. Hospitalizations with principal and secondary GI diagnoses decreased by 13.3% and 8.2% from 2019 to 2020, respectively. Most GI diagnoses decreased in 2020, with a few exceptions including alcoholic liver disease (increased by 7.8% as a principal diagnosis) and acute liver failure (increased by 11.6% as a secondary diagnosis). The mortality rate of hospitalizations with GI disease increased in 2020 compared with 2019 (for principal diagnosis: adjusted odds ratio 1.08, 95% confidence interval 1.03-1.13, P=0.001; for secondary diagnosis: adjusted odds ratio 1.10, 95% confidence interval 1.07-1.13, P<0.001). Most GI procedures decreased except for a notable 8.3% increase in gastrostomy. The per-GI-hospitalization rate of procedures increased for hospitalizations with a principal GI diagnosis (56.4% vs 55.6%, P=0.003) or unchanged for hospitalizations with secondary GI diagnoses (18.3% vs 18.2%, P=0.512). The COVID-19 pandemic resulted in a decrease in the volume of GI hospitalizations and procedures in 2020, but there was an increase in the mortality rate and some specific diagnoses including alcoholic liver disease and acute liver failure. These findings will likely enlighten future research and healthcare resource allocation for GI diseases.

Contemporary European practice in transcatheter aortic valve implantation: results from the 2022 European TAVI Pathway Registry.

A steep rise in the use of transcatheter aortic valve implantation (TAVI) for the management of symptomatic severe aortic stenosis occurred. Minimalist TAVI procedures and streamlined patient pathways within experienced Heart Valve Centres are designed to overcome the challenges of ever-increasing procedural volume. The 2022 European TAVI Pathway Survey aims to describe contemporary TAVI practice across Europe. Between October and December 2022, TAVI operators from 32 European countries were invited to complete an online questionnaire regarding their current practice. Responses were available from 147 TAVI centres in 26 countries. In 2021, the participating centres performed a total number of 27,223 TAVI procedures, with a mean of 185 TAVI cases per centre (median 138; IQR 77-194). Treatment strategies are usually (87%) discussed at a dedicated Heart Team meeting. Transfemoral TAVI is performed with local anaesthesia only (33%), with associated conscious sedation (60%), or under general anaesthesia (7%). Primary vascular access is percutaneous transfemoral (99%) with secondary radial access (52%). After uncomplicated TAVI, patients are transferred to a high-, medium-, or low-care unit in 28%, 52%, and 20% of cases, respectively. Time to discharge is day 1 (12%), day 2 (31%), day 3 (29%), or day 4 or more (28%). Reported adoption of minimalist TAVI techniques is common among European TAVI centres, but rates of next-day discharge remain low. This survey highlights the significant progress made in refining TAVI treatment and pathways in recent years and identifies possible areas for further improvement.

Performance of Perioperative Tasks for Women Undergoing Anti-incontinence Surgery: Developed by the AUGS Quality Improvement and Outcomes Research Network.

Surgery for the correction of stress urinary incontinence is an elective procedure that can have a dramatic and positive impact on quality of life. Anti-incontinence procedures, like inguinal hernia repairs or cholecystectomies, can be classified as high-volume/low-morbidity procedures. The performance of a standard set of perioperative tasks has been suggested as one way to optimize quality of care in elective high-volume/low-morbidity procedures. Our primary objective was to evaluate the performance of 5 perioperative tasks-(1) offering nonsurgical treatment, (2) performance of a standard preoperative prolapse examination, (3) cough stress test, (4) postvoid residual test, and (5) intraoperative cystoscopy for women undergoing surgery for stress urinary incontinence-compared among surgeons with and without board certification in female pelvic medicine and reconstructive surgery (FPMRS). This study was a retrospective chart review of anti-incontinence surgical procedures performed between 2011 and 2013 at 9 health systems. Cases were reviewed for surgical volume, adverse outcomes, and the performance of 5 perioperative tasks and compared between surgeons with and without FPMRS certification. Non-FPMRS surgeons performed fewer anti-incontinence procedures than FPMRS-certified surgeons. Female pelvic medicine and reconstructive surgery surgeons were more likely to perform all 5 perioperative tasks compared with non-FPMRS surgeons. After propensity matching, FPMRS surgeons had fewer patients readmitted within 30 days of surgery compared with non-FPMRS surgeons. Female pelvic medicine and reconstructive surgery surgeons performed higher volumes of anti-incontinence procedures, were more likely to document the performance of the 5 perioperative tasks, and were less likely to have their patients readmitted within 30 days.

Association Between Hospital Volume and 30-Day Readmissions After Transcatheter Mitral Valve Edge-to-Edge Repair

Data on the association between hospital procedural volume and 30-day readmissions after mitral valve transcatheter edge-to-edge repair (mTEER) are limited. We used the 2019 Nationwide Readmissions Database to identify hospitals that performed at least 5 mTEERs. Hospitals were categorized based on tertiles of annual mTEER volume as low-volume (5 to 13), medium-volume (14 to 28), and high-volume (29 to 171). Multivariable hierarchical logistic regression models and restricted cubic spline analyses were used to examine the association between hospital mTEER volume and 30-day readmissions. Median (interquartile range) annual hospital mTEER volume was 20 (11.5 to 34). Of 234 hospitals included in the study, 77 (32.9%), 77 (32.9%), and 80 (34.2%) were categorized as low-volume, medium-volume, and high-volume. Of 5,574 index mTEER procedures included in this study, 634 (11.4%), 1,353 (24.3%), and 3,587 (64.3%) were performed at low-volume, medium-volume, and high-volume centers, respectively. In the overall study cohort, rates of 30-day all-cause readmissions after mTEER were 13.2%. In multivariable analyses, there was no significant association between hospital mTEER volume (as a categorical variable) and 30-day all-cause or cause-specific (cardiac, non-cardiac, heart failure) readmissions. Similarly, no significant relation was observed between hospital mTEER volume as a continuous variable and 30-day all-cause or cause-specific readmissions in restricted cubic spline analysis. In conclusion, in a nationally representative sample of 234 hospitals with >5,500 mTEER procedures, we found no association between annual hospital mTEER volume and 30-day all-cause or cause-specific readmissions.

Implications of Public Interest in Colonoscopy: Analysis of Google Trends Data From 12 European Countries.

Colorectal cancer (CRC) is one of the deadliest diseases in the European Union. Colonoscopy remains the gold standard of CRC screening. Analysis of colonoscopy-related Google Trends (GT; Google LLC, Mountain View, California, United States) data could provide useful information regarding interest in colonoscopy and potential barriers making patients unwilling to attend screening programs. Data were collected using GT for the main search term "colonoscopy" and the two most related queries. Colonoscopy volumes were extracted from the Eurostat database. Due to limited Eurostat data availability, analysis was performed from January 2004 to December 2015 for each of the 12 included countries. Univariate linear regression analysis demonstrated statistically significant correlations between annual search volumes of "colonoscopy" and the annual number of colonoscopies performed in included countries (R2 = 0.923, P<.001). Trend analysis showed that the cumulative search volumes for "colonoscopy" gradually increased through the analyzed period. The spectrum of the most related queries encompassed "preparation for colonoscopy", "endoscopy", "after endoscopy", "colon", "colonoscopy diet", "virtual colonoscopy", "colonoscopy under anesthesia", "waiting times for colonoscopy" and "colonoscopy price". For eight out of nine queries, statistically significant correlations with procedure volumes were revealed. GT could be a useful tool in assessing public interest in colonoscopy. Potential barriers that prevent people from attending CRC screening programs were identified. The study demonstrated that the internet has become an important field for CRC screening promotion. GT utility for colonoscopy and CRC screening providers was highlighted. This was the first analysis of GT data in colonoscopy focused on European countries.

Trends in Orthopedic Management of Distal Radius Fractures Among Medicare Beneficiaries From 2019 to 2020: A Claims Analysis

Radius and ulna fractures are among the most common fractures. These fractures are managed through operative or nonsurgical treatment, with varying implications in terms of cost and functional outcome. There are few studies that robustly characterize the management of distal radius fractures (DRFs) in the United States during the COVID-19 pandemic. Furthermore, this has not been studied among the Medicare patient population, who are particularly vulnerable to fragility fractures and COVID-19. The purpose of this study is to analyze the services provided to Medicare beneficiaries both before and during the COVID-19 pandemic to determine how procedure volume was affected in this patient population. We retrospectively analyzed services using the physician or supplier procedure summary data from the Centers for Medicare and Medicaid Services. All services provided by physicians between January 1, 2019, and December 31, 2020, were included. The data were stratified by US census region using insurance carrier number and pricing locality codes. We also compared data between states that maintained governors affiliated with the Democratic or Republican parties for the duration of the study. There was an overall decrease in claims regarding DRFs management from 2019 to 2020. There was a dramatic decline in procedure volume (-6.3% vs-12.9%). Of all distal radius related claims there was a relative increase in the proportion of operatively managed DRFs in 2020, from 50.2% to 52.0%. The Midwest saw the greatest decline in operatively managed DRFs, whereas the West experienced the smallest per-capita decline across all procedures. After separating the data by party affiliation, it was also found that operative and nonsurgical procedure volumes fell more sharply in states with Democratic governors. This study shows a decrease in DRF procedural volume among Medicare beneficiaries. This data suggests that the operative and nonsurgical management of DRFs may have been affected by pandemic factors such as quarantine guidelines and supply chain or resource limitations. This may assist surgeons and health care systems in predicting how similar crises may affect operative volume. Therapeutic IV.

Roadmap on the use of artificial intelligence for imaging of vulnerable atherosclerotic plaque in coronary arteries.

Artificial intelligence (AI) is likely to revolutionize the way medical images are analysed and has the potential to improve the identification andanalysis of vulnerable or high-risk atherosclerotic plaques in coronary arteries, leading to advances in the treatment of coronary artery disease. However, coronary plaque analysis is challenging owing to cardiac and respiratory motion, as well as the small size of cardiovascular structures. Moreover, the analysis of coronary imaging data is time-consuming, can be performed only by clinicians with dedicated cardiovascular imaging training, and is subject to considerable interreader and intrareader variability. AI has the potential to improve the assessment of images of vulnerable plaque in coronary arteries, but requires robust development, testing and validation. Combining human expertise with AI might facilitate the reliable and valid interpretation of images obtained using CT, MRI, PET, intravascular ultrasonography and optical coherence tomography. In this Roadmap, we review existing evidence on the application of AI to the imaging of vulnerable plaque in coronary arteries and provide consensus recommendations developed by an interdisciplinary group of experts on AI and non-invasive and invasive coronary imaging. We also outline future requirements of AI technology to address bias, uncertainty, explainability and generalizability, which are all essential for the acceptance of AI and its clinical utility in handling the anticipated growing volume of coronary imaging procedures.

Association of Hospital Procedural Volume With Outcomes of Left Ventricular Assist Device Placement

With the advancement in device technology, the use of durable left ventricular assist devices (LVADs) has increased significantly in recent years. However, there is a dearth of evidence to conclude whether patients who undergo LVAD implantation at high-volume centers have better clinical outcomes than those receiving care at low- or medium-volume centers. We analyzed the hospitalizations using the Nationwide Readmission Database for the year 2019 for new LVAD implantation. Baseline comorbidities and hospital characteristics were compared among low- (1-5 procedures/year), medium- (6-16 procedures/year) and high-volume (17-72 procedures/year) hospitals. The volume/outcome relationship was analyzed using the annualized hospital volume as a categorical variable (tertiles) as well as a continuous variable. Multilevel mixed-effect logistic regression and negative binomial regression models were used to determine the association of hospital volume and outcomes, with tertile 1 (low-volume hospitals) as the reference category. A total of 1533 new LVAD procedures were included in the analysis. The inpatient mortality rate was lower in the high-volume centers compared with the low-volume centers (9.04% vs 18.49%, aOR 0.41, CI0.21-0.80; P = 0.009). There was a trend toward lower mortality rates in medium-volume centers compared with low-volume centers; however, it did not reach statistical significance (13.27% vs 18.49%, aOR 0.57, CI0.27-1.23; P = 0.153). Similar results were seen for major adverse events (composite of stroke/transient ischemic attack and in-hospital mortality). There was no significant difference in bleeding/transfusion, acute kidney injury, vascular complications, pericardial effusion/hemopericardium/tamponade, length of stay, cost, or 30-day readmission rates between medium- and high-volume centers compared to low-volume centers. Our findings indicate lower inpatient mortality rates in high-volume LVAD implantation centers and a trend toward lower mortality rates in medium-volume LVAD implantation centers compared to lower-volume centers.

The Big Data Gap: Asymmetric Information in the Ophthalmology Residency Match Process and the Argument for Transparent Residency Data.

Background The ophthalmology match is an important step for graduating medical students that defines their future career. Residency programs demonstrate significant variability due to differences in size, location, research output, subspecialty exposure, surgical case load, and alumni fellowship/practice placement. Despite the importance of informed decision-making, applicants often find limited, inconsistent information about potential programs. Purpose The purpose of this study was to characterize and identify gaps in the information available to residents in the 2022 to 2023 Match. Methods The SFMatch Web site was reviewed to identify programs included as well as characteristics cited on each program's webpage. Program webpages were used to evaluate availability and consistency of data on site surgical caseload, fellowship slots, and teaching staff. Results Of the 121 programs included on SFMatch, 23 (19%) provided no data on August 15, 2022 (15 days prior to application submission deadline) and 9 (7%) lacked program data on October 15, 2022. Though most programs provided mean cataract volume, data on volume of other procedures for graduating residents was highly variable and occasionally misleading. Programs did not provide information on several academic and social considerations that may influence match ranking choice. Conclusion Applicants often must read "between the lines" to identify residency program strengths and weaknesses. Data crucial to informing the application process remain sparse, unavailable, or spread across resources. Limited data increases applicant dependence on word-of-mouth knowledge to inform decision-making. This might reduce diversity by limiting successful applicants to those with existing connections within the field.

Practice Patterns in the Operative Management of Pediatric Thyroid Disease Across Surgical Specializations

BackgroundMultiple surgical specializations are involved in the operative management of pediatric thyroid disease, but current practice patterns remain unknown. The objective of this study was to examine current practice patterns in the operative management of pediatric thyroid disease, specifically comparing practices across different surgical specializations including pediatric surgery, pediatric otolaryngology, general surgery, adult otolaryngology, and endocrine-focused general surgery. MethodsChildren 0-18 years-old undergoing thyroid surgery from 2015 to 2019 were identified using the Healthcare Cost and Utilization Project State Inpatient Databases and State Ambulatory Surgery and Services Databases across 6 states. Surgeon specialization was determined for all included surgeons. Patient and hospital characteristics were compared across surgical specializations. Clinical outcomes including hypocalcemia/hypoparathyroidism, recurrent laryngeal nerve injury, hematoma, and wound infection were assessed. ResultsA total of 1241 pediatric thyroidectomies performed by 363 surgeons were included. Procedures were most frequently performed by pediatric surgeons (34.9%). Only 7.2% of procedures were performed by adult general surgeons. There were statistically significant differences in patient age, sociodemographics, surgical indications, and type of procedure performed between specializations (p < 0.05).
