Consultant revision hip arthroplasty volumes and new consultant volume trajectories in England, Wales, Northern Ireland, and the Isle of Man.

This study describes the variation in the annual volumes of revision hip arthroplasty (RHA) undertaken by consultant surgeons nationally, and the rate of accrual of RHA and corresponding primary hip arthroplasty (PHA) volume for new consultants entering practice. National Joint Registry (NJR) data for England, Wales, Northern Ireland, and the Isle of Man were received for 84,816 RHAs and 818,979 PHAs recorded between April 2011 and December 2019. RHA data comprised all revision procedures, including first-time revisions of PHA and any subsequent re-revisions recorded in public and private healthcare organizations. Annual procedure volumes undertaken by the responsible consultant surgeon in the 12 months prior to every index procedure were determined. We identified a cohort of 'new' HA consultants who commenced practice from 2012 and describe their rate of accrual of PHA and RHA experience. The median annual consultant RHA volume, averaged across all cases, was 21 (interquartile range (IQR) 11 to 34; range 0 to 181). Of 1,695 consultants submitting RHA cases within the study period, the top 20% of surgeons by annual volume performed 74.2% of total RHA case volume. More than half of all consultants who had ever undertaken a RHA maintained an annual volume of just one or fewer RHA, however, collectively contributed less than 3% of the total RHA case volume. Consultant PHA and RHA volumes were positively correlated. Lower-volume surgeons were more likely to undertake RHA for urgent indications (such as infection) as a proportion of their practice, and to do so on weekends and public holidays. The majority of RHAs were undertaken by higher-volume surgeons. There was considerable variation in RHA volumes by indication, day of the week, and between consultants nationally. The rate of accrual of RHA experience by new consultants is low, and has important implications for establishing an experienced RHA consultant workforce.

How to perform effective cryoballooon ablation of the left atrial roof: Considerations after experiencing more than 1000 cases.

Cryoballoon ablation (CBA) of the left atrial (LA) roof in addition to a pulmonary vein isolation has been expected to improve the clinical outcomes post-atrial fibrillation (AF) ablation. We demonstrated the characteristics and efficacy of CBA of the LA roof through our experience with a large volume of procedures. Among 1036 AF ablation procedures with CBA of the LA roof, 834 patients who underwent a de novo ablation were analyzed. Complete LA roof line conduction block was obtained in 767 patients (92.0%) solely by CBA (Group A). Compared with the other patients (Group B), the mean nadir balloon temperature during CBA of the LA roof (-44.5 ± 5.6°C for Group A vs. -40.5 ± 7.5°C for Group B, p < .01) and number of cryoballoon applications during the LA roof ablation with a circular mapping catheter located in the left superior pulmonary vein (1.3 ± 0.8 for Group A vs. 1.6 ± 1.0 for Group B, p = .02) were significantly lower in Group A. A multivariate analysis revealed that those were predictors of a complete LA roof conduction block after only CBA. The 1-year Kaplan-Meier atrial arrhythmia free rate estimates were 80.6% for Group A and 59.0% for Group B (p < .01). Complete LA roof line conduction block could be obtained with a cryoballoon without touch-up ablation in most cases. The LA roof CBA with a circular mapping catheter located in the right superior pulmonary vein was preferable to obtaining complete LA roof conduction block, which was important with regard to the clinical outcomes.

Length of intraabdominal measurement of bowel (LIMB)

BackgroundLaparoscopic Roux-en-Y gastric bypass (RYGB) is one of the most commonly performed bariatric surgeries. The steep associated learning curve is dependent on the training facility, laparoscopic experience, and overall procedural volume. William Beaumont Army Medical Center (WBAMC) has been accredited as a bariatric center of excellence and trains resident surgeons in the performance of RYGB. ObjectiveThis study aimed to investigate the accuracy and precision of a bariatric center of excellence's training of surgical residents in terms of laparoscopic measurements of simulated small bowel. This will act as a surrogate for how well surgical residents learn to run the small bowel during bariatric procedures and how their accuracy and precision change over time in training. SettingThis study took place at William Beaumont Army Medical Center, a bariatric center of excellence and training institution. MethodsParticipants included surgical residents from WBAMC. Participants used a laparoscopic trainer and two bowel graspers to measure both a collapsing garden hose (simulated bowel) and a nylon rope (control material) to 75 cm (cm) and 125 cm (cm), three times each, with recordings of time required to do so, actual distance measured, and technique used. ResultsFifteen residents participated in the study. Residents displayed accuracy of 21.6 %. 33%of residents were precise for the 75 cm measurement, and 53 % of residents were precise for the 125-cm measurement. PGY-4 residents were the most accurate while PGY-3 residents were the most precise. There were no statistical differences between junior (PGY 1–4) and senior residents (PGY 5–6) in accuracy or precision in the measurement of 75-cm or 125-cm. No statistical differences were found measuring the hose versus rope in accuracy nor precision. PGY-4 residents completed the task in the least amount of time while PGY-2 residents took the longest to complete each task. ConclusionsIn general, residents are neither precise nor accurate in measurements of simulated bowel lengths, and experience does not contribute to either. Time in residency correlates with laparoscopic speed but not with accuracy nor precision. Extrapolating this data to attending surgeons suggests that estimated lengths of small bowel that are ‘run’ or measured during laparoscopic cases are neither accurate nor precise. More investigation must be performed in this area.

Trends and disparities in deep brain stimulation utilization in the United States: a Nationwide Inpatient Sample analysis from 1993 to 2017

Deep brain stimulation (DBS) is an approved treatment option for Parkinson's Disease (PD), essential tremor (ET), dystonia, obsessive-compulsive disorder and epilepsy in the United States. There are disparities in access to DBS, and clear understanding of the contextual factors driving them is important. Previous studies aimed at understanding these factors have been limited by single indications or small cohort sizes. The aim of this study is to provide an updated and comprehensive analysis of DBS utilization for multiple indications to better understand the factors driving disparities in access. The United States based National Inpatient Sample (NIS) database was utilized to analyze the surgical volume and trends of procedures based on indication, using relevant ICD codes. Predictors of DBS use were analyzed using a logistic regression model. DBS-implanted patients in each indication were compared based on the patient-, hospital-, and outcome-related variables. Our analysis of 104,356 DBS discharges from 1993 to 2017 revealed that the most frequent indications for DBS were PD (67%), ET (24%), and dystonia (4%). Although the number of DBS procedures has consistently increased over the years, radiofrequency ablation utilization has significantly decreased to only a few patients per year since 2003. Negative predictors for DBS utilization in PD and ET cohorts included age increase and female sex, while African American status was a negative predictor across all cohorts. Significant differences in patient-, hospital-, and outcome-related variables between DBS indications were also determined. Demographic and socioeconomic-based disparities in DBS use are evident. Although racial disparities are present across all indications, other disparities such as age, sex, wealth, and insurance status are only relevant in certain indications. This work was supported by Alan & Susan Hudson Cornerstone Chair in Neurosurgery at University Health Network.

Perceptions and Practice Patterns of Urologists Relating to Intrarenal Pressure During Ureteroscopy: Findings from a Global Cross-Sectional Analysis.

Objectives: To explore beliefs and practice patterns of urologists regarding intrarenal pressure (IRP) during ureteroscopy (URS). Methods: A customized questionnaire was designed in a 4-step iterative process incorporating a systematic review of the literature and critical analysis of topics/questions by six endourologists. The 19-item questionnaire interrogated perceptions, practice patterns, and key areas of uncertainty regarding ureteroscopic IRP, and was disseminated via urologic societies, networks, and social media to the international urologic community. Consultants/attendings and trainees currently practicing urology were eligible to respond. Quantitative responses were compiled and analyzed using descriptive statistics and chi-square test, with subgroup analysis by procedure volume. Results: Responses were received from 522 urologists, practicing in six continents. The individual question response rate was >97%. Most (83.9%, 437/515) respondents were practicing at a consultant/attending level. An endourology fellowship incorporating stone management had been completed by 59.2% (307/519). The vast majority of respondents (85.4%, 446/520) scored the perceived clinical significance of IRP during URS ≥7/10 on a Likert scale. Concern was uniformly reported, with no difference between respondents with and without a high annual case volume (p = 0.16). Potential adverse outcomes respondents associated with elevated ureteroscopic IRP were urosepsis (96.2%, 501/520), collecting system rupture (80.8%, 421/520), postoperative pain (67%, 349/520), bleeding (63.72%, 332/520), and long-term renal damage (26.1%, 136/520). Almost all participants (96.2%, 501/520) used measures aiming to reduce IRP during URS. Regarding the perceived maximum acceptable threshold for mean IRP during URS, 30 mm Hg (40 cm H2O) was most frequently selected [23.2% (119/463)], with most participants (78.2%, 341/463) choosing a value ≤40 mm Hg. Conclusions: This is the first large-scale analysis of urologists' perceptions of ureteroscopic IRP. It identifies high levels of concern among the global urologic community, with almost unanimous agreement that elevated IRP is associated with adverse clinical outcomes. Equipoise remains regarding appropriate IRP limits intraoperatively and the most appropriate technical strategies to ensure adherence to these.

Ophthalmology procedure trends in the United States during the COVID-19 pandemic.

To evaluate the relationship between the COVID-19 pandemic and ophthalmic procedural volume. A retrospective cohort study using TriNetX, a federated electronic health record's research network was done. Monthly Current Procedural Terminology-specific volumes per healthcare organization were clustered chronologically to calculate average volumes into 3-month seasons to calculate average procedural volumes. An aggregate of the total pandemic period (March 2020-August 2021) was compared to corresponding figures in pre-pandemic timeframes. Intravitreal injections were the most prevalent procedure in this time period with 320,106 occurrences. Phacoemulsification cataract surgery was the second most prevalent (N = 176,095) procedure. From March 2020 to August 2021, a mean pandemic volume of 266.7 (SD = 15) was observed, a 5% decrease (p < 0.05) in procedures compared to the pre-pandemic mean of 280.8 (SD = 26.1). Spring 2020 exhibited the sharpest seasonal decrease in procedural volume (- 88%). The largest count of statistically significant increases in procedure volume was in Spring 2021 (+ 18%). The aggregate mean volume per HCO showed significant decreases for 11 out of 17 procedures in the 12month March 2020-February 2021 timeframe and significant decreases for 10 out of 17 procedures over the 18-month March 2020-August 2021 pandemic period. This study highlights the relative inverse relationship between COVID-19 cases and ophthalmic procedure volume in America. Quantifying ophthalmic procedure trends is important in retrospectively assessing surgical disruptions and prospectively accommodating delayed surgeries. Furthermore, awareness of these trends could help ophthalmologists prepare should similar disruptions occur in the setting of future pandemics or national disasters.

Radiología intervencionista en pediatría: no es un juego de niños

Pediatric interventional radiology is a dynamic and growing subspecialty. The new training pathways in interventional radiology, the maintenance of skills with a small volume of cases or complex procedures, the limited availability of specific pediatric equipment and materials, the effects of sedation or anesthesia on neurodevelopment or radiological on neurodevelopment or radiation protection pose significant challenges and opportunities.

The Impact of the COVID-19 Pandemic on Surgical Services in Brazil's Healthcare System: A Retrospective Cross-Sectional Study.

Background The coronavirus disease 2019 (COVID-19) pandemic provoked disruptions in healthcare delivery, leading to the cancellation and postponement of various health services, including surgery. Numerous countries closed their borders and established laws mandating the use of face masks and social distancing and enforced lockdowns, and various activities were constrained. Brazil, the largest and most populous country in Latin America, also experienced a rapid and sustained surge in infections and deaths. Brazil was the most severely impacted nation in Latin America. The impact of the pandemic on surgical services in Brazil has not been adequately studied since most studies only cover the early phases of the pandemic. Thus, this study aimed to assess the impact of the COVID-19 pandemic on surgical services throughout the entire period. Methods A retrospective cross-sectional design was used to examine surgical cases from 2019 to 2022 and compared the following indicators: (1) number of hospital admissions, (2) length of hospital stay (LOS) (in days), and (3)volume of urgent and elective procedures. Data was divided into four time periods, pre-pandemic (March-December 2019), pandemic (March-December 2020), recovery (March-December 2021), and post-pandemic (March-December 2022), and was analyzed for the number of admissions and LOS based on surgical procedures performed by stratifying according to region, sex, age, and type of surgery (urgent versus elective). Results The number of admissions for surgical procedures ranged between 859,646and 4,015,624for 2019, 686,616and 3,419,234for 2020,787,791and 3,829,019for 2021, and760,512and 3,857,817for 2022 for the category of region; 4,260,900and 5,991,775for 2019, 3,594,117and 4,984,710for 2020,4,182,640 and 5,590,808for 2021, and4,077,651 and5,561,928for 2022 for the category of sex; and 2,170,288 and 3,186,117 for 2019, 1,516,830and2,825,189for 2020,1,748,202and3,030,272for 2021, and1,900,023and2,859,179for 2022 for the category of age.The variable age showed a comparable trend, albeit with an expressive decline for surgeries in the age range of 0-19 years. The LOS (in days)for surgical procedures ranged between110,157 and 910,846for 2019,58,562 and897,734for 2020,67,926 and904,137for 2021, and100,467and823,545for 2022. Thoracic surgery indicated no statistically significant difference in the number of admissions and LOS.Elective surgeries had a decline in the number of admissions and LOS, a 13% and 9.3% decline between 2019 and 2020, respectively. Urgent surgeries experienced a slight decrease in admissions and LOS, with a decline of 2.4% and 2.8% between 2019 and 2020, respectively. Conclusions Population characteristics, such as age, sex, and region, showed decreased hospital admissions during the pandemic, followed by a recovery towardpre-pandemic levels afterward. The number of surgical admissions and the length of hospital stays decreased during the pandemic but gradually returned to pre-pandemic levels in the recovery and post-pandemic phases. Notably, thoracic surgery remained statistically consistent across all periods, indicating its emergency nature compared to other surgeries. Thus, we conclude that the pandemic had minimal impact on thoracic surgery cases, contributing to a stable trend.

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.
