Emergency department visits and hospitalizations among patients with sickle cell disease in illinois, 2016-2020.

Sickle cell disease (SCD) state level surveillance data are limited. We performed a retrospective review of emergency department (ED) visits and hospitalizations from individuals with SCD in Illinois (2016-2020) using the Illinois Health and Hospital Association's Comparative Health Care and Hospital Data Reporting Services. There were 48,094 outpatient ED visits and 31,686 hospitalizations. Most visits (67%) occurred in Cook County, were covered by public insurance (77%) and were from individuals with medium high (40.3%) or high (36.1%) poverty levels. SCD healthcare utilization remains high and surveillance data may inform SCD program development and resource allocation at the state level.AbbreviationsCDCCenters for Disease Control and PreventionEDEmergency DepartmentFDAFood & Drug AdministrationICDInternational Classification of DiseasesILIllinoisSCDSickle cell disease.

Closure of Licensed Pediatric Beds in Health Care Markets Within Illinois.

OBJECTIVE: Our objective was to understand the market characteristics related to closures of licensed pediatric hospital beds that may be related to increasing regionalization of pediatric hospital care. METHODS: We performed a retrospective descriptive analysis of 110 hospitals with licensed pediatric hospital beds from a statewide survey of health care facilities (2012-2017) and administrative data of hospital admissions (2013-2018) in Illinois. We quantified closures of licensed pediatric hospital beds and categorized hospital bed closures by hospital and market characteristics. RESULTS: From 2012 through 2017, the number of licensed pediatric beds declined from 1706 to 1254 (-26.5%). Over the same time period, annual pediatric inpatient days minimally changed (+1.1%), while annual pediatric inpatient days at hospitals affiliated with the Children's Hospital Association increased (+30.5%). After accounting for re-openings, the 33 hospitals that closed all licensed pediatric beds fit 4 distinct typologies: 1) Hospitals with minimal pediatric volume throughout the study (n = 19); 2) Hospitals that sustained at least 50% of their pediatric volume after closure of licensed pediatric beds (n = 8); 3) Hospitals with low market share in metropolitan areas (n = 5); and 4) Hospital with a decline in pediatric market share, while a nearby hospital saw a corresponding rise in pediatric market share (n = 1). CONCLUSIONS: In Illinois, licensed pediatric hospital beds declined while pediatrics inpatient days stayed the same over a recent 6-year period. Typologies of closures describe the nuanced dynamics leading to decline of pediatric hospital beds. Understanding these patterns is critical to ensure that children receive quality pediatric-tailored care.

Interregional Transfers for Pandemic Surges.

BACKGROUND: Hospital inpatient and intensive care unit (ICU) bed shortfalls may arise due to regional surges in volume. We sought to determine how interregional transfers could alleviate bed shortfalls during a pandemic. METHODS: We used estimates of past and projected inpatient and ICU cases of coronavirus disease 2019 (COVID-19) from 4 February 2020 to 1 October 2020. For regions with bed shortfalls (where the number of patients exceeded bed capacity), transfers to the nearest region with unused beds were simulated using an algorithm that minimized total interregional transfer distances across the United States. Model scenarios used a range of predicted COVID-19 volumes (lower, mean, and upper bounds) and non-COVID-19 volumes (20%, 50%, or 80% of baseline hospital volumes). Scenarios were created for each day of data, and worst-case scenarios were created treating all regions' peak volumes as simultaneous. Mean per-patient transfer distances were calculated by scenario. RESULTS: For the worst-case scenarios, national bed shortfalls ranged from 669 to 58 562 inpatient beds and 3208 to 31 190 ICU beds, depending on model volume parameters. Mean transfer distances to alleviate daily bed shortfalls ranged from 23 to 352 miles for inpatient and 28 to 423 miles for ICU patients, depending on volume. Under all worst-case scenarios except the highest-volume ICU scenario, interregional transfers could fully resolve bed shortfalls. To do so, mean transfer distances would be 24 to 405 miles for inpatients and 73 to 476 miles for ICU patients. CONCLUSIONS: Interregional transfers could mitigate regional bed shortfalls during pandemic hospital surges.

Medical Student Consulting: Providing Students Leadership and Business Opportunities While Positively Impacting the Community.

Introduction: Medical schools are increasingly attempting to prepare future physicians for diverse new leadership roles in the health care system. Many schools have implemented didactic leadership curricula, with varying levels of structure and success. Project-based learning via completion of real-world projects using a team-based approach remains an underutilized approach to developing student leadership skills. Methods: We designed and implemented the Medical Educational Consulting Group (Med ECG)-a student-run consulting program that provides medical students with opportunities to develop leadership skills by completing consulting projects with local clients. We provide an overview of the Med ECG model, including a combination of didactic training sessions and project-based learning via both simulation and real-world projects. Surveys were used to evaluate the value of Med ECG to clients, the community, and students. Results: Fourteen medical students (eight first-years, two second-years, three third-years, and one fourth-year, including five dual-degree candidates) completed the Med ECG program. Client feedback pointed to the value of Med ECG's projects and their impact on the community through partner organizations. Finally, linear regression analysis showed a strong positive correlation (R2 = .61) between the amount of effort devoted to various leadership attributes and the perceived improvement while working with Med ECG. Discussion: Med ECG's experiences show that a medical student-led project-based learning program is a novel way to develop leadership skills for future physician leaders. Efforts to replicate these types of programs will help additional students develop their leadership and business skills, making a positive impact outside of the classroom.

The Challenge of Measuring Surgeon Spending for Payment Policies.

OBJECTIVE: Our objective was to understand the reliability of profiling surgeons on average health care spending. SUMMARY OF BACKGROUND DATA: Under its Merit-based Incentive Payment System (MIPS), Medicare will measure surgeon spending and tie performance to payments. Although the intent of this cost-profiling is to reward low-cost surgeons, it is unknown whether surgeons can be accurately distinguished from their peers. METHODS: We used Michigan Medicare and commercial payer claims data to construct episodes of surgical care and to calculate average annual spending for individual surgeons. We then estimated the "reliability" (ie, the ability to distinguish surgeons from their peers) of these cost-profiles and the case-volume that surgeons would need in order to achieve high reliability [intraclass correlation coefficient (ICC) >0.8]. Finally, we calculated the reliability of 2 alternative methods of profiling surgeons (ie, using multiple years of data and grouping surgeons by hospitals). RESULTS: We found that annual cost-profiles of individual surgeons had poor reliability; the ICC ranged from <0.001 for CABG to 0.061 for cholecystectomy. We found that few surgeons in the state of Michigan have sufficient case-volume to be reliably compared; 1% had the minimum yearly case. Finally, we found that the reliability of the cost-profiles can be improved by measuring spending at the hospital-level and/or by incorporating additional years of data. CONCLUSION: These findings suggest that the Medicare program should measure surgeon spending at a group level or incorporate multiple years of data to reduce misclassification of surgeon performance in the MIPS program.

Quantifying Geographic Variation in Health Care Outcomes in the United States before and after Risk-Adjustment.

BACKGROUND: Despite numerous studies of geographic variation in healthcare cost and utilization at the local, regional, and state levels across the U.S., a comprehensive characterization of geographic variation in outcomes has not been published. Our objective was to quantify variation in US health outcomes in an all-payer population before and after risk-adjustment. METHODS AND FINDINGS: We used information from 16 independent data sources, including 22 million all-payer inpatient admissions from the Healthcare Cost and Utilization Project (which covers regions where 50% of the U.S. population lives) to analyze 24 inpatient mortality, inpatient safety, and prevention outcomes. We compared outcome variation at state, hospital referral region, hospital service area, county, and hospital levels. Risk-adjusted outcomes were calculated after adjusting for population factors, co-morbidities, and health system factors. Even after risk-adjustment, there exists large geographical variation in outcomes. The variation in healthcare outcomes exceeds the well publicized variation in US healthcare costs. On average, we observed a 2.1-fold difference in risk-adjusted mortality outcomes between top- and bottom-decile hospitals. For example, we observed a 2.3-fold difference for risk-adjusted acute myocardial infarction inpatient mortality. On average a 10.2-fold difference in risk-adjusted patient safety outcomes exists between top and bottom-decile hospitals, including an 18.3-fold difference for risk-adjusted Central Venous Catheter Bloodstream Infection rates. A 3.0-fold difference in prevention outcomes exists between top- and bottom-decile counties on average; including a 2.2-fold difference for risk-adjusted congestive heart failure admission rates. The population, co-morbidity, and health system factors accounted for a range of R2 between 18-64% of variability in mortality outcomes, 3-39% of variability in patient safety outcomes, and 22-70% of variability in prevention outcomes. CONCLUSION: The amount of variability in health outcomes in the U.S. is large even after accounting for differences in population, co-morbidities, and health system factors. These findings suggest that: 1) additional examination of regional and local variation in risk-adjusted outcomes should be a priority; 2) assumptions of uniform hospital quality that underpin rationale for policy choices (such as narrow insurance networks or antitrust enforcement) should be challenged; and 3) there exists substantial opportunity for outcomes improvement in the US healthcare system.

Accessory renal arteries: Prevalence in resistant hypertension and an important role in nonresponse to radiofrequency renal denervation.

OBJECTIVE: The aim of this study was to understand the role of accessory renal arteries in resistant hypertension, and to establish their role in nonresponse to radiofrequency renal denervation (RDN) procedures. BACKGROUND: Prior studies suggest a role for accessory renal arteries in hypertensive syndromes, and recent clinical trials of renal denervation report that these anomalies are highly prevalent in resistant hypertension. This study evaluated the relationships among resistant hypertension, accessory renal arteries, and the response to radiofrequency (RF) renal denervation. METHODS: Computed Tomography Angiography (CTA) and magnetic resonance imaging (MRI) scans from 58 patients with resistant hypertension undergoing RF renal denervation (RDN) were evaluated. Results were compared with CT scans in 57 healthy, normotensive subjects undergoing screening as possible renal transplant donors. All scans were carefully studied for accessory renal arteries, and were correlated with long term blood pressure reduction. RESULTS: Accessory renal arteries were markedly more prevalent in the hypertensive patients than normotensive renal donors (59% vs 32% respectively, p=0.004). RDN had an overall nonresponse rate of 29% (response rate 71%). Patients without accessory vessels had a borderline higher response rate to RDN than those with at least one accessory vessel (83% vs 62% respectively, p=0.076) and a higher RDN response than patients with untreated accessory arteries (83% vs 55%; p=0.040). For accessory renal arteries and nonresponse, the sensitivity was 76%, specificity 49%, with positive and negative predictive values 38% and 83% respectively. CONCLUSIONS: Accessory renal arteries were markedly over-represented in resistant hypertensives compared with healthy controls. While not all patients with accessory arteries were nonresponders, nonresponse was related to both the presence and non-treatment of accessory arteries. Addressing accessory renal arteries in future clinical trials may improve RDN therapeutic efficacy.
