Ethical and Bias Considerations in Artificial Intelligence (AI)/Machine Learning.

As artificial intelligence (AI) gains prominence in pathology and medicine, the ethical implications and potential biases within such integrated AI models will require careful scrutiny. Ethics and bias are important considerations in our practice settings, especially as increased number of machine learning (ML) systems are being integrated within our various medical domains. Such machine learning based systems, have demonstrated remarkable capabilities in specified tasks such as but not limited to image recognition, natural language processing, and predictive analytics. However, the potential bias that may exist within such AI-ML models can also inadvertently lead to unfair and potentially detrimental outcomes. The source of bias within such machine learning models can be due to numerous factors but can be typically put in three main buckets (data bias, development bias and interaction bias). These could be due to the training data, algorithmic bias, feature engineering and selection issues, clinical and institutional bias (i.e. practice variability), reporting bias, and temporal bias (i.e. changes in technology, clinical practice or disease patterns). Therefore despite the potential of these AI-ML applications, their deployment in our day to day practice also raises noteworthy ethical concerns. To address ethics and bias in medicine, a comprehensive evaluation process is required which will encompass all aspects such systems, from model development through clinical deployment. Addressing these biases is crucial to ensure that AI-ML systems remain fair, transparent, and beneficial to all. This review will discuss the relevant ethical and bias considerations in AI-ML specifically within the pathology and medical domain.

First step to environmentally sustainable endoscopy practice: a prospective study of minimizing multiple device use during screening colonoscopy at a large tertiary center.

The healthcare sector generates 8% of greenhouse gas emissions in the USA, of which gastrointestinal (GI) endoscopy is the third largest contributor. Single-use tools are a major contributor to modifiable waste generation during GI endoscopy. Through a quality improvement initiative, we aimed to reduce endoscopy waste by urging gastroenterologists to be mindful of tools used during polypectomies by avoiding using multiple tools. We discussed green endoscopy initiatives in monthly journal club and business meetings. Over 14 weeks, 210 patients were included in the pre-intervention group and 112 in the post-intervention group. At baseline, 34% of colonoscopies required no intervention, 32% required one tool (either biopsy forceps or a snare), and 33% required multiple tools. After the intervention, the use of just one tool increased (17 percentage point increase; P=0.003) and the use of multiple tools decreased significantly (16 percentage point decrease; P=0.002). The odds ratio for use of a single tool compared with multiple tools after the intervention was 3.0 (95%CI 1.6 to 5.5; P=0.005). This single-center quality improvement study noted a significant change in practice patterns favoring the use of a single tool over multiple tools during colonoscopies after an environmentally conscious practice intervention was applied. This intervention can be readily applied to reduce endoscopy-related waste.

Abstract 4137135: Trends in Mechanical Circulatory Support After the New Heart Allocation Policy

Background: In October 2018 a new heart allocation policy (NHAP) was implemented, which resulted in patients with Intra-aortic balloon pumps (IABP) being upgraded to status-two. We sought to determine practice pattern changes in mechanical circulatory support (MCS) use as a result of the NHAP. Hypothesis: Changes in the new heart allocation policy may lead to shifts in choice of mechanical circulatory support. Methods: A retrospective analysis was conducted using the National Inpatient Sample (NIS) between 2017–2020. Hospitalizations for cardiogenic shock were identified, and stratified based on whether the patients were admitted before or after the NHAP. Baseline characteristics were compared between these cohorts, and the primary outcome of interest was the use of MCS and transplant before and after the NHAP. Subgroup analyses included patients only in transplant centers, non-transplant centers, and those who eventually underwent transplant. Results: A total of 689,935 hospitalizations were included in the final analysis, of which 279,230 (40.5%) were before the NHAP, and 410,705 (59.5%) were after. In allcomers, hospitalizations after the NHAP were less likely to undergo IABP (Adjusted odds ratio [OR] 0.81, p<0.01) and LVAD (Adjusted OR 0.73, p<0.01). These findings were consistent in most subgroup analyses. Patients who underwent transplant after the NHAP however were more than twice as likely to have received a IABP compared to those admitted prior to the NHAP (adjusted OR 2.58; p<0.01). Conclusion: IABP placement after the NHAP increased in patients who underwent transplant, as opposed to allcomers or patients who did not undergo transplant. This change in utilization of MCS may be reflective of perceived benefits and biases in regards to transplantation candidacy.

Increasing Utilization of Extended Oral Antibiotic Prophylaxis Following Total Knee Arthroplasty from 2010 to 2022

Extended oral antibiotic (EOA) prophylaxis has been shown to reduce rates of periprosthetic joint infection in high-risk patients following total knee arthroplasty (TKA). Although national societies' recommendations against their use and clinical efficacy remain controversial, the increase in the literature surrounding EOA prophylaxis suggests a potential change in practice patterns that may warrant the creation of national guidelines. The purpose of this study was to investigate the trends in the utilization of EOA prophylaxis following TKA from 2010 to2022. Patients who underwent primary or aseptic revision TKA between 2010 and 2022 were identified in a national administrative claims database. Temporal trends in EOA usage following primary or revision TKA were calculated, and secondary analysis examined rates of utilization across demographics, including patients considered at high risk for infection. In total, 1,258,759 primary and 91,530 aseptic revision TKA patients were included in this study. From 2010 to 2022, EOA prescriptions increased by 321 and 368% following primary and revision TKA, respectively. Rates of utilization among high-risk individuals were similar to those of the general population. The use of EOA prophylaxis after TKA has increased significantly since 2010. Given their increasing usage and variation in prescription patterns among patients at high risk of infection, guidelines surrounding their use are necessary to promote antibiotic stewardship while preventing rates of infection.

Temporal Trends in Thyroid Nodule Size on Ultrasonography

In recent years, concern has grown around the overdetection of thyroid cancer. Changes to thyroid nodule risk stratification systems and guidelines were made to improve diagnostic yield. It is not known how these advancements have affected the size of thyroid nodules reported on ultrasonography over time. To evaluate change in reported nodule size since 1990, particularly between studies of thyroid ultrasonography obtained for diagnostic vs screening purposes. The systematic review included original research studies that reported thyroid nodule size in adults undergoing their first thyroid ultrasonography. Excluded studies were those that included patients with known thyroid disease, prior thyroid ultrasonography, nodules identified through other imaging modalities, and/or that had constraints on nodule size and/or characteristics. PubMed, SCOPUS, CENTRAL, and CINAHL were reviewed from January 1990 to March 2021. Study characteristics, patient demographic characteristics, nodule size, and ultrasonography techniques were independently extracted by multiple observers. The size of thyroid nodules reported via ultrasonography over time. Mixed-effects meta-regression models were used to evaluate mean nodule size (1) overall, (2) in studies that used ultrasonography diagnostically, and (3) in studies that used ultrasonography for screening. A total of 11 963 patients were included; the mean (SD) age was 47.6 (5.2) years. A total of 1097 studies were identified; of these, 395 full-text articles were assessed, and 18 studies met inclusion criteria. All were done at academic institutions. Altogether, these studies had 11 963 patients who underwent a first thyroid ultrasonography. Reported mean nodule size increased 0.52 mm each year from 1990 to 2021 (95% CI, 0.2-0.81). Diagnostic subgroup mean nodule size increased 0.57 mm each year from 1990 to 2021 (95% CI, 0.21-0.93). Screening subgroup mean nodule size decreased by 0.23 mm each year up to 2012 (95% CI, -0.40 to -0.07). The results of this systematic review and meta-analysis suggest that thyroid nodule size reported on diagnostic ultrasonography has increased over time in conjunction with changes in risk stratification systems, nodule guidelines, and radiology practice patterns. Conversely, a decrease in size reported in asymptomatic, ultrasonography-screened populations was observed. Findings from screening studies show that subcentimeter nodules are prevalent and easily identified with ultrasonography, but clinical relevance is questionable. Altogether, these results may provide insight into how ultrasonography guidelines and practice patterns have changed thyroid nodule reporting over time and can inform future guidelines and policies associated with thyroid nodule management.

Intravenous thrombolysis in patients on direct oral anticoagulants: A survey of NIH StrokeNet sites

BackgroundPatients with suspected ischemic stroke and use of Direct Oral Anticoagulants (DOACs) within 48 h are excluded from thrombolysis. We aimed to determine practice patterns across institutions in the NIH StrokeNet, a network of hospitals to conduct NIH-funded stroke clinical trials, in the United States. MethodsA survey was sent electronically to all NIH StrokeNet regional coordinating centers. The survey questions were geared towards understanding practice patterns with intravenous thrombolysis use in patients on DOACs. We reported proportions and percentages answers to the questions. We compared the likelihood of thrombolysis use in patients with recent DOAC ingestion (never vs. all other responses) across characteristics of survey responder using Chi Square. ResultsA total of 83 site principal investigators completed the survey; 78.3 % would never give thrombolysis to an otherwise eligible patients within 12-24 h from last DOAC ingestion and 54.2 % would never give thrombolysis to an otherwise eligible patient within 24-48 h from last DOAC ingestion. A higher proportion of vascular neurologists would never give thrombolysis in patients with DOAC ingestion within 12-48 h compared to other subspecialties (60.7 % vs. 36.4 %, p = 0.05). Nearly, 80 % would change their practice if a well-designed prospective study demonstrated that the symptomatic intracranial hemorrhage rate is not >5 %. ConclusionsA well-designed prospective study with a set safety threshold is likely to change practice patterns in giving thrombolysis in patients with recent DOAC ingestion, particularly among vascular neurologists who are more likely to never give thrombolysis in this setting.

Impact of Sugammadex Introduction on Using Neuromuscular Blockade and Endotracheal Intubation in a Pediatric Hospital: A Retrospective, Observational Cross-Sectional Study.

Sugammadex is a neuromuscular blockade (NMB) reversal agent introduced in the United States in 2016, which allows the reversal of deep NMB, not possible with neostigmine. Few data describe associated practice changes, if any, in NMB medication use that may have resulted from its availability. We hypothesized that after institutional introduction, use of NMB agents increased. Furthermore, as NMB medication is typically used when the airway has been secured with an endotracheal tube (ETT), we speculated that ETT use may have also increased over the same time period as a result of sugammadex availability. This was a single-center cross-sectional study of patients ages 2 to 17 years undergoing general anesthesia for surgical cases where anesthesia providers often have discretion over NMB medication use or whether to use an ETT versus a laryngeal mask airway (LMA), comparing the time periods 2014 to 2016 (presugammadex) to 2017 to 2019 (early sugammadex) and 2020 to 2022 (established sugammadex). Outcomes included use of (1) any nondepolarizing NMB medication during the case and (2) an ETT versus LMA. We used generalized linear mixed models to examine changes in practice patterns over time. We also examined whether patient age group and in-room provider (resident versus certified registered nurse anesthetist [CRNA]) were associated with increased NMB medication or ETT use. There were 25,638 eligible anesthetics. Patient and surgical characteristics were similar across time periods. In adjusted analyses, the odds of NMB medication use increased from 2017 to 2019 (odds ratio [OR], 1.55, 95% confidence interval [CI], 1.38-1.75) and 2020 to 2022 (OR, 5.62, 95% CI, 4.96-6.37) relative to 2014 to 2016, and were higher in older children (age 6-11 years vs 2-5 years OR, 1.81, 95% CI, 1.63-2.01; age 12-17 years vs 2-5 years OR, 7.01, 95% CI, 6.19-7.92) and when the primary in-room provider was a resident rather than a CRNA (OR, 1.24, 95% CI, 1.12-1.37). The odds of ETT use declined 2017 to 2019 (OR, 0.69, 95% CI, 0.63-0.75) and 2020 to 2022 (OR, 0.71, 95% CI, 0.65-0.78), more so in older children (age 6-11 years vs 2-5 years OR, 0.45, 95% CI, 0.42-0.49; age 12-17 years vs 2-5 years OR, 0.28, 95% CI, 0.25-0.31). Resident presence at induction was associated with increased odds of ETT use (OR, 1.50, 95% CI, 1.38-1.62). The decision to use NMB medication as part of an anesthetic plan increased substantially after sugammadex became available, particularly in older children and cases staffed by residents. ETT use declined over the study period.

A Dwindling Matter: An Analysis of Medicare Reimbursement for Endocrine Surgery Procedures from 2000-23.

To evaluate Medicare reimbursement trends for endocrine surgeries from 2000-23. As the population ages, demand for endocrine surgeries is expected to increase. Understanding reimbursement trends is essential to ensure the financial sustainability of endocrine surgery. Data were extracted from Medicare Inpatient and Outpatient Hospital datasets, National Summary, and Physician Fee Look-up Files for nine common thyroid, parathyroid and adrenal surgeries. Data were adjusted for inflation. Descriptive statistics, compound annual growth rate (CAGR), and linear regression models were built to evaluate practice and reimbursement trends. From 2000-23, there was a 63.8% increase in endocrine surgery volume. However, inflation-adjusted average procedure reimbursements decreased by 43.2% from $1709 to $972 (CAGR -2.4%), which is the largest decrease for any surgical subspecialty reported in the published literature. At the current CAGR, the average estimated reimbursement is projected to decrease to $868 by 2030 (P<0.001). Average facility reimbursements for inpatient and outpatient hospitalizations increased. However, substantial practice pattern shifts in the study period led to decreased overall facility reimbursements, with a $17.9 million decrease in total inpatient reimbursements between 2016-21 that was only partially offset by a $3.2 million increase in outpatient hospital reimbursements. Medicare procedure reimbursements for endocrine surgeries have been outpaced by inflation, with large decreases since 2000. Concurrent changes in practice patterns have also resulted in markedly fewer inpatient stays leading to lower total facility reimbursements. Our data raise concern over the financial sustainability of the endocrine surgery field as the demand for endocrine surgery procedures increases.

Impact of the IDEA Collaboration Study on Real-World Practice Patterns of Adjuvant Chemotherapy in Patients With Stage III Colon Cancer: A Population-Based Study.

The International Duration Evaluation of Adjuvant Chemotherapy (IDEA) collaboration showed no significant clinical difference in outcomes in patients with stage III colon cancer (CC) treated with 3 versus 6 months of oxaliplatin-based adjuvant chemotherapy (O-ACT). We aimed to assess change in real-world practice patterns before and after publication of the IDEA study. This retrospective cohort study included patients age ≥18 years with stage III CC diagnosed between January 1, 2012, and December 31, 2020. Eligible patients received >1 dose of ACT between March 20, 2012, and May 10, 2021 inclusive. They were categorized into pre-IDEA (diagnosed before March 31, 2018) and post-IDEA (diagnosed on or after April 1, 2018) groups. The primary outcome was the median duration and type of ACT and factors associated with a shorter duration. Secondary outcomes were 2-year overall survival (OS) and cancer-specific survival (CSS). In total, 740 patients were included (median age, 64 years, range, 27-90; 52.7% male). 48.8% had pT4 and/or pN2 disease. 77% received O-ACT. In the post-IDEA era, capecitabine plus oxaliplatin (CAPOX) ACT use increased (22.8%-50.7%, P < .001), and median duration of treatment was significantly shorter (2.7 v 4.8 months, P < .001). Factors associated with shorter O-ACT duration included diagnosis in the post-IDEA era (odds ratio, 2.08, P = .002), absence of pT4 and/or pN2 disease (hazard ratio [HR], 1.71, P = .01), and receipt of CAPOX (HR, 2.58, P < .001). Two-year OS and CSS were comparable between pre- and post-IDEA eras (OS 95% v 94%; CSS 96% v 96%). Our study shows that the results of the IDEA trial have been largely adopted in clinical practice with shorter duration of ACT in low-risk stage III CC.

Seven years of Non-invasive Follicular Thyroid Neoplasm with Papillary-like Nuclear Features (NIFTP): Rate of Acceptance and Variation of Diagnostic Approaches Across Different Continents.

Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced as a new entity replacing the diagnosis of noninvasive encapsulated follicular variant of papillary thyroid carcinoma (PTC). Significant variability in the incidence of NIFTP diagnosed in different world regions has been reported. To investigate the rate of adoption of NIFTP, change in practice patterns, and uniformity in applying diagnostic criteria among pathologists practicing in different regions. Two surveys distributed to pathologists of the International Endocrine Pathology Discussion Group with multiple-choice questions on NIFTP adoption into pathology practice and whole slide images of 5 tumors to collect information on nuclear score and diagnosis. Forty-eight endocrine pathologists, including 24 from North America, 8 from Europe, and 16 from Asia/Oceania completed the first survey and 38 the second survey. A 94% adoption rate of NIFTP by the pathologists was found. Yet, the frequency of rendering NIFTP diagnosis was significantly higher in North America than in other regions (P = .009). While the highest concordance was found in diagnosing lesions with mildly or well-developed PTC-like nuclei, there was significant variability in nuclear scoring and diagnosing NIFTP for tumors with moderate nuclear changes (nuclear score 2) (case 2, P < .05). Pathologists practicing in North America and Europe showed a tendency for lower thresholds for PTC-like nuclei and NIFTP than those practicing in Asia/Oceania. Despite a high adoption rate of NIFTP across geographic regions, NIFTP is diagnosed more often by pathologists in North America. Significant differences remain in diagnosing intermediate PTC-like nuclei and respectively NIFTP, with more conservative nuclear scoring in Asia/Oceania, which may explain the geographic differences in NIFTP incidence.

Association of COVID-19 and the Prevalence of In-person Versus Telehealth Primary Care Visits and Subsequent Impacts on Tobacco Use Assessment and Referral for Cessation Assistance.

The COVID-19 pandemic dramatically altered patterns of healthcare delivery. Smoking remains an important risk factor for multiple chronic conditions and may exacerbate more severe symptoms of COVID-19. Thus, it is important to understand how pandemic-induced changes in primary care practice patterns affected smoking assessment and cessation assistance. Electronic health record data from eight community health centers were examined from March 1, 2019 to February 28, 2022. Data include both telehealth (phone and video) and in-person office visits and represent 310 388 visits by adult patients. Rates of smoking assessment, provision of referral to counseling, and orders for smoking cessation medications were calculated. Comparisons by visit mode and time period were examined using generalized estimating equations and logistic regression. The proportion of telehealth visits was < 0.1% 1 year prior to COVID-19 onset and, 54.5% and 34.1% 1 and 2 years after. The odds of asking about smoking status and offering a referral to smoking cessation counseling were significantly higher during in-person versus telehealth visits; adjusted odds ratios (AOR) (95% CI) = 15.0 (14.7 to 15.4) and AOR (95% CI) = 6.5 (3.0 to 13.9), respectively. The interaction effect of visit type * time period was significant for ordering smoking cessation medications. Telehealth visits were significantly less likely to include smoking status assessment and referral to smoking cessation counseling compared to in-person visits. Given that smoking assessment and cessation assistance do not require face-to-face interactions with health care providers, continued efforts are needed to ensure provision at all visits, regardless of modality. The COVID-19 pandemic dramatically altered patterns of healthcare-seeking and delivery with a considerable rise in telehealth visits. This study examined 1 year prior to the onset of COVID-19 and 2 years after to evaluate the assessment of tobacco use and assistance with tobacco cessation and differences during in-person versus telehealth visits. Tobacco assessment was 15 times more likely during in-person versus telehealth visits in the 2 years post onset of COVID-19. Given that telehealth visits are likely to continue, ensuring that patients are regularly assessed for tobacco regardless of visit modality is an important concern for health systems.

Gestational carrier cycles: embryology trends, national guideline compliance, and resultant perinatal outcomes in the United States, 2014–2020

The increased use of gestational carriers has expanded family-building opportunities for people and couples unable to carry pregnancies on their own. National American Society of Reproductive Medicine guidelines for gestational carriers have changed over time to reflect advances in reproductive technology and mounting evidence supporting the medical benefits associated with singleton gestations. Assess changes in gestational carrier cycle practice patterns and resultant pregnancy outcomes in the United States in relation to changing national American Society of Reproductive Medicine guidelines, which changed in 2013 and2017. This retrospective study used data from the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System and included all cycles that were reported from 2014-2020 involving an embryo transfer to a gestational carrier. Binomial regression models evaluated trends in preimplantation genetic testing for aneuploidy, American Society of Reproductive Medicine guideline adherence, number of embryos transferred, and pregnancy outcomes over time. Of the 40,177 gestational carrier transfer cycles from 2014-2020, there was a significant increase in frozen-thawed cycles (41.3% increase), use of assisted hatching (53.4% increase), intracytoplasmic sperm injection (50.0% increase), and preimplantation genetic testing for aneuploidy (155.7% increase). The likelihood of preimplantation genetic testing for aneuploidy was higher in 2020 than in 2014 for autologous oocyte transfers to gestational carriers, both for those aged ≥38 years (adjusted relative risk, 2.38 [95% confidence interval, 2.11-2.70]) and than those aged <38 years (adjusted relative risk, 2.85 [95% confidence interval, 2.58-3.15]). As preimplantation genetic testing for aneuploidy usage increased, single embryo transfer rose for both autologous (adjusted relative risk, 2.22 [95% confidence interval, 1.94-2.50]) and donor cycles (relative risk, 1.91 [95% confidence interval, 1.81-2.02]). This shift toward single embryo transfer corresponded with a decrease in multiple embryo transfer by 79.2% and subsequent decreases in multiple gestations by 68.8% in donor and 73.6% in autologous oocyte cycles from 2014-2020. Gestational carrier cycles remained highly adherent to changing American Society of Reproductive Medicine guidelines throughout the study period. Among live births, there was a 19.4% and 7.9% increase in term deliveries among donor and autologous oocyte cycles, respectively, from 2014 to2020. Practice patterns have drastically changed throughout the study period, with major increases in the use of preimplantation genetic testing for aneuploidy, intracytoplasmic sperm injection, assisted hatching, and frozen transfers. In response to changing American Society of Reproductive Medicine guidelines, the use of multiple embryo transfers has decreased for gestational carrier cycles with subsequent decreases in multiple gestations and miscarriages and slight increases in live birth rates.

Abstract PO4-04-03: Empowering Oncologists to Develop Individualized Management Strategies for HER2+ Metastatic Breast Cancer: Findings from a Quality Improvement Initiative

Abstract Background: Rapidly evolving evidence in the treatment of metastatic HER2+ metastatic breast cancer (MBC) can present challenges in aligning practice with the latest clinical data and guideline recommendations. In this ongoing quality improvement initiative, we identify and address real-world challenges healthcare professionals (HCPs) face in individualizing treatment plans, adverse event management, and patient-centered care for HER2+ MBC. Methods: From 9/2022 to 12/2022, 22 HCPs who treat patients with breast cancer (BC) along with 52 patients with HER2+ MBC from 2 large US community oncology clinics completed tethered surveys assessing practice patterns, challenges, and attitudes related to individualized and patient-centered care for HER2+MBC. Patient charts (n=100) were audited to assess current practice patterns and to track changes over time. Inclusion criteria included a confirmed HER2+ MBC diagnosis, prescription for two or more lines of HER2+ breast cancer treatment, and ≥ 1 visit in the one-year chart abstraction period. HCPs participated in audit-feedback sessions to assess site-specific challenges and gaps and developed action plans for improvement. Follow-up chart audits and HCP surveys will evaluate changes in practice patterns 6 months after the educational intervention. Results: The most frequently reported HCP challenges included coordination of care (41%) and individualizing treatment plans (32%). The most frequently reported patient challenges included feeling confident in treatment plan (30%) and being unable to meet work or home responsibilities (22%). In tethered surveys, there were discordant findings between patient and HCP perceptions related to goals for treatment, patient education, and patient-centered care. For example, 82% of HCPs reported often or always asking patients about treatment preferences, but only 8% of patients reported their doctor asked. While HCPs overwhelmingly thought surviving as long as possible was their patients’ top goal (82%), patients reported their top goals for treatment were improving quality of life (57%) and controlling symptoms (41%). Additionally, while HCPs thought patients had the most difficulty managing nausea/vomiting (68%) and diarrhea (59%), patients reported they have the most difficulty managing fatigue (46%) and hair loss (44%). Baseline chart audits highlighted several areas for improvement in guideline-aligned care, including treatment selection, sequencing, and supportive care. Based on identified gaps, providers developed and implemented action plans, such as increasing use of patient navigators, referring patients for palliative care at time of diagnosis, improving multidisciplinary team-based approaches, and implementing tools and resources to stay up-to-date on clinical evidence and guidelines. Full findings from baseline surveys and chart audits will be presented, along with follow-up surveys and chart audits to measure impact. Conclusions: Through this QI initiative, we identified gaps in individualized, guideline-aligned, patient-centered care for patients with HER2+ MBC, and HCPs developed and are implementing action plans for improvement. The methods and findings from this initiative demonstrate key opportunities to improve outcomes for patients with HER2+ MBC in community oncology clinics.

An Analysis of American Urological Association Census Trends: Earlier Planned Retirement and Practice Pattern Changes May Exacerbate the Urology Workforce Shortage

ObjectiveTo explore how changes in planned retirement age, practice setting, and physician productivity may impact the workforce shortage in urology. MethodsWe compared data between the 2015 and 2022 American Urological Association census, a specialty-wide annual survey which collects data on demographics, practice patterns and procedures from a representative sample of US urologists. Workforce productivity was measured by the self-reported number of hours worked per week and patients seen per week. A novel formula was developed to demonstrate how planned retirement age and productivity impact the workforce’s production capacity. ResultsThe total number of practicing urologists increased during the period from 2015 to 2022 (11,990 to 13,976), while the mean age of practicing urologists decreased slightly (55.0 to 54.5 years; p <0.002). During this period, the mean planned age of retirement for all urologists decreased from 68.9 years to 67.7 (p <0.001). Urologists in solo practice had a significantly higher planned age of retirement at 71.9 years (p <0.001) as compared to all other practice models. The number of patients seen per week for all urologists decreased from 78.7 to 72.9 (p <0.001). The amount of hours worked per week remained relatively constant between the study periods. The maximum possible number of patients seen by the workforce prior to retirement increased by only 2.4% during the study interval. ConclusionThough the US urology workforce is growing and the mean age is decreasing, decreases in planned retirement age and productivity may offset these gains and intensify the physician shortage for US urologists.

Reduced mortality associated with pulmonary embolism response team consultation for intermediate and high-risk pulmonary embolism: a retrospective cohort study

BackgroundThe management of acute pulmonary embolism (PE) has become increasingly complex with the expansion of advanced therapeutic options, resulting in the development and widespread adoption of multidisciplinary Pulmonary Embolism Response Teams (PERTs). Much of the literature evaluating the impact of PERTs has been limited by pre- postimplementation study design, leading to confounding by changes in global practice patterns over time, and has yielded mixed results. To address this ambiguity, we conducted a retrospective cohort study to evaluate the impact of the distinct exposures of PERT availability and direct PERT consultation.MethodsAt a single tertiary center, we conducted propensity-matched analyses of hospitalized patients with intermediate or high-risk PE. To assess the impact of PERT availability, we evaluated the changes in 30-day mortality, hospital length of stay (HLOS), time to therapeutic anticoagulation (TAC), in-hospital bleeding complications, and use of advanced therapies between the two years preceding and following PERT implementation. To evaluate the impact of direct PERT consultation, we conducted the same analyses in the post-PERT era, comparing patients who did and did not receive PERT consultation.ResultsSix hundred eighty four patients were included, of which 315 were pre-PERT patients. Of the 367 postPERT patients, 201 received PERT consultation. For patients who received PERT consultation, we observed a significant reduction in 30-day mortality (5% vs 20%, OR 0.38, p = 0.0024), HLOS.(-5.4 days, p < 0.001), TAC (-0.25 h, p = 0.041), and in-hospital bleeding (OR 0.28, p = 0.011).These differences were not observed evaluating the impact of PERT presence in pre-vs postimplementation eras.ConclusionsWe observed a significant reduction in 30-day mortality, hospital LOS, TAC, and in-hospital bleeding complications for patients who received PERT consultation without an observed difference in these metrics when comparing the pre- vs post-implementation eras. This suggests the benefits stem from direct PERT involvement rather than the mere existence of PERT. Our data supports that PERT consultation may provide benefit to patients with acute intermediate or high-risk PE and can be achieved without a concomitant increase in advanced therapies.

Lessons Learned from Coronary Revascularization Appropriateness Statements for Application to Peripheral Artery Disease

Appropriate Use Criteria (AUC) are evidence-based criteria developed in a methodologically robust manner with the input of expert providers across a wide range of disciplines and practice settings. AUC have been successfully implemented in the diagnosis and management of a wide range of cardiovascular disease processes. AUC have demonstrated clear potential for influencing meaningful change in practice patterns with regards to high-value, high-quality care in cardiovascular pathologies. Potential for similar impact in the management of peripheral artery disease, specifically for patients presenting with intermittent claudication (IC), may be limited due to unique challenges. These challenges include multidisciplinary interventionalists, variability in existing AUC across specialties, and financial incentives influencing physician behavior. AUC serve to benefit patients by improving outcomes, and adoption of AUC is a critical step toward improving the quality of care provided to patients with IC. Societal support is necessary for effective AUC implementation.

Volume and Practice-Setting Shift of Laryngology Procedures During the COVID-19 Pandemic: A Reg-ENT Database Analysis.

The onset of the coronavirus disease 2019 (COVID-19) pandemic changed practice patterns throughout medicine. The purpose of this study is to evaluate changes in the volume and location setting of laryngology procedures after the onset of COVID-19. Retrospective database cohort study. Reg-ENT registry. Retrospective review from 2017 to 2022 of patients who underwent a laryngology procedure identified by procedure code categorized by site of service code-"ambulatory surgical" versus "office" setting. Based on March 2020 as the cutoff point, the procedures were designated as pre-COVID versus COVID time period. A total of 5989 patients underwent laryngology procedures. Forty-two percent more procedures were performed in the COVID period (n = 3780) versus pre-COVID (n = 2209). Pre-COVID, the procedure distribution between office and ambulatory surgical setting was 70% (n = 1546) compared with 30% (663). This shifted to 77% (n = 2920) and 23% (n = 860) during COVID, P = .9. The most common diagnoses associated with laryngology procedures during the study period were vocal fold paralysis 47% (n = 2831), dysphonia 33% (n = 1392), and laryngotracheal stenosis 14% (n = 838). These trends remained in both pre-COVID and COVID time periods. After the start of the pandemic, among patients undergoing laryngology procedures, there was a 93% increase (n = 284-549) in the diagnosis of laryngotracheal stenosis, 70% increase (n = 520-882 patients) in dysphonia and 69% increase (n = 1054-1777) in vocal fold paralysis. An increase in laryngology procedures performed after the onset of the COVID-19 pandemic was identified with an overall procedural shift to the office-setting.

Practice Management Strategies Among Current Members of the American Association of Hip and Knee Surgeons

BackgroundA survey was conducted at the 2023 Annual Meeting of the American Association of Hip and Knee Surgeons (AAHKS) to assess practice management strategies among current AAHKS members. MethodsMembers of AAHKS used an app to answer both multiple-choice and “yes or no” questions related to a variety of issues related to their practices. ResultsThe number of AAHKS members in private practice (37%) continues to decline, and 4% are now in private equity–employed practices. Fee for service (30%) and relative value units (30%) are the major forms of compensation. The number of AAHKS members that perform total joint arthroplasties at ambulatory surgery centers continues to increase, and supply chain issues (91%) remain a problem. There has been a decrease in surgeon participation in bundled payment programs and gainsharing arrangements with hospitals. ConclusionsThis member’s survey provides valuable information regarding practice patterns. The shift to outpatient surgery has continued. Future surveys will be performed to monitor changes in practice patterns over time.

Reducing the carbon footprint of operating rooms through education on the effects of inhalation anesthetics on global warming: A retrospective study.

Environmental concerns, especially global warming, have prompted efforts to reduce greenhouse gas emissions. Healthcare systems, including anesthesia practices, contribute to these emissions. Inhalation anesthetics have a significant environmental impact, with desflurane being the most concerning because of its high global warming potential. This study aimed to educate anesthesiologists on the environmental impact of inhalation anesthetics and assess changes in awareness and practice patterns, specifically reducing desflurane use. This study included data from patients who underwent surgery under general anesthesia 1 month before and after education on the effects of inhalation anesthetics on global warming. The primary endpoint was a change in inhalational anesthetic use. Secondary endpoints included changes in carbon dioxide equivalent (CO2e) emissions, driving equivalent, and medical costs. After the education, desflurane use decreased by 50%, whereas sevoflurane use increased by 50%. This shift resulted in a reduction in the overall amount of inhalational anesthetics used. The total CO2e and driving-equivalent values decreased significantly. The cost per anesthesia case decreased, albeit to a lesser extent than expected. Education on the environmental impact of inhalation anesthetics has successfully altered anesthesiologists' practice patterns, leading to reduced desflurane usage. This change has resulted in decreased CO2e emissions and has had a positive effect on mitigating global warming. However, further research is required to assess the long-term impact of such education and the variability in practice patterns across different institutions.
