Relationship Between Insurance Status and Receipt of Cardiac Tests and Procedures During Hospitalization: A Cross-Sectional Study.

Prior analyses of the relationship between insurance status and receipt of tests and procedures have yielded conflicting findings and have focused on outpatient care. We sought to characterize the relationship between primary payer and diagnostic and procedural intensity, comparing rates of cardiac tests and procedures in matched hospitalized Medicaid and commercially insured patients. We created a propensity score-matched sample of Medicaid and commercially insured adults hospitalized at all acute care hospitals in Kentucky, Maryland, New Jersey, and North Carolina from 2016 to 2018. The main outcome was receipt of a cardiac test or procedure: echocardiogram, stress test, cardiac catheterization (elective, in acute coronary syndrome, in ST-segment-elevation myocardial infarction), and pacemaker and subcutaneous cardiac rhythm monitor implantation. Generalized linear models with a hospital-specific indicator variable were estimated to calculate the adjusted odds of a commercially insured patient receiving a given test or procedure relative to a Medicaid patient. Models controlled for race, ethnicity, and zip code income quartile. Commercially insured patients were more likely to receive each cardiac test or procedure, with adjusted odds ratios ranging from 1.16 (95% CI, 1.00-1.34) for cardiac catheterization in ST-segment-elevation myocardial infarction to 1.40 (95% CI, 1.27-1.54) for pacemaker implantation. Hospitalized commercially insured patients were more likely to undergo a range of cardiac tests and procedures, some of which may represent low-value care. This may be driven by a combination of physician and patient preference, financial incentives, and social determinants of health. Our findings support the need for hospital payment models focused on increasing value and reducing inequities.

Premorbid Incidence of Mental Health and Substance Abuse Disorders in Facial Trauma Patients.

A retrospective study. Facial trauma is a prevalent cause of morbidity and mortality with increasing incidence over recent decades. Few studies have examined the prevalence of mental health and substance abuse disorders at the time of diagnosis. Herein we investigate the psychosocial demographics associated with facial trauma. The 2016 State Inpatient Database (SID) was used to identify patients with facial trauma from all hospitals in New York, Florida, and Maryland. A non-trauma control group undergoing elective same-day surgeries at ambulatory surgical centers in Florida, Kentucky, Nevada, North Carolina, New York, and Maryland was identified using the State Ambulatory Surgery and Services Database (SASD) from the Healthcare Cost and Utilization Project (HCUP). 777 patients were identified with facial trauma and compared to 500 patients without facial fractures. Patients with facial fractures were statistically significantly more likely to have a substance abuse disorder (OR 34.78, P < .001) or mental health disorder (OR 2.75, P < .001) compared to controls. Patients with facial fractures were significantly more likely to be black than white (OR 4.80, P < .001). Patients with facial fractures were significantly more likely to have Medicaid compared to Medicare (OR 2.12, P = .005). Patients with facial fractures are more likely to have premorbid substance abuse and mental health disorders as compared to controls.

Race and Ethnicity and Diagnostic Testing for Common Conditions in the Acute Care Setting

Overuse of diagnostic testing is pervasive, but the extent to which it varies by race and ethnicity in the acute care setting is poorly understood. To use a previously validated diagnostic intensity index to evaluate differences in diagnostic testing rates by race and ethnicity in the acute care setting, which may serve as a surrogate for diagnostic test overuse. This was a cross-sectional study of emergency department (ED) discharges, hospital observation stays, and hospital admissions using administrative claims among EDs and acute care hospitals in Kentucky, Maryland, North Carolina, and New Jersey, from 2016 through 2018. The diagnostic intensity index pairs nonspecific principal discharge diagnoses (nausea and vomiting, abdominal pain, chest pain, and syncope) with related diagnostic tests to estimate rates of nondiagnostic testing. Adults with an acute care encounter with a principal discharge diagnosis of interest were included. Data were analyzed from January to February 2024. Race and ethnicity (Asian, Black, Hispanic, White, other [including American Indian, multiracial, and multiethnic], and missing). Receipt of a diagnostic test. Generalized linear models with a hospital-specific indicator variable were estimated to calculate the adjusted odds ratio of receiving a test related to the principal discharge diagnosis by race and ethnicity, controlling for primary payer and zip code income quartile. Of 3 683 055 encounters (1 055 575 encounters [28.7%] for Black, 300 333 encounters [8.2%] for Hispanic, and 2 140 335 encounters [58.1%] for White patients; mean [SD] age of patients with encounters, 47.3 [18.8] years; 2 233 024 encounters among females [60.6%]), most (2 969 974 encounters [80.6%]) were ED discharges. Black compared with White patients discharged from the ED with a diagnosis of interest had an adjusted odds ratio of 0.74 (95% CI, 0.72-0.75) of having related diagnostic testing. No other racial or ethnic disparities of a similar magnitude were observed in any acute care settings. In this study, White patients discharged from the ED with a nonspecific diagnosis of interest were significantly more likely than Black patients to receive related diagnostic testing. The extent to which this represents diagnostic test overuse in White patients vs undertesting and missed diagnoses in Black patients deserves further study.

Vaccinating the Frontlines: A Qualitative Exploration of Hospital Healthcare Worker Perspectives on Influenza and COVID-19 Immunization.

Although they face higher occupational risk of contracting viral respiratory infections, hospital healthcare worker vaccine hesitancy persists. While most studies have used survey methods to quantify the prevalence of and reasons for healthcare worker vaccine hesitancy, this study employs a qualitative approach to understand their attitudes and beliefs associated with influenza and COVID-19 vaccination. To understand frontline healthcare worker experiences and perspectives on influenza and COVID-19 vaccination, 30 semi-structured interviews were conducted in summer/fall 2022 with staff recruited from two Johns Hopkins hospitals in Maryland. An in-depth, key informant interview was conducted with an expert in public health audience engagement. Interviews were audio recorded and transcribed for thematic and Framework analysis using NVivo software (QSR International, Melbourne, Australia). Healthcare workers engaged in little influenza vaccine information seeking due to their familiarity with the disease and low perceived disease severity. Approximately half (n=16) of healthcare workers reported no vaccine hesitancy towards influenza or COVID-19 vaccines. No physicians or physician assistants expressed any vaccine hesitancy, while most nurses expressed some (n=10). More than half of the women (n=14) expressed COVID-19 vaccine hesitancy compared to none of the men. Structural factors including hospital tier, unit assignment, and professional role influenced perceived risk of disease exposure and subsequent healthcare worker vaccination decisions. Institutional policies, including mandates and a pro-vaccine environment encouraged vaccination uptake. Healthcare workers reported being more receptive to vaccine messaging that focused on protection from disease, scientific and public health data and their heightened occupational exposure to pathogens. Despite their medical knowledge, healthcare workers are susceptible to vaccine hesitancy. Strategies to address specific concerns are needed and can be informed by our findings. A flexible and multi-pronged approach that considers individual anxieties, workplace structures, and the need for open communication with tailored messaging is necessary to promote vaccine acceptance in healthcare settings. What is already known on this topic: Healthcare worker vaccine hesitancy has been associated with many factors including race, gender, age and concerns about vaccine safety.What this study adds: Much of the research on healthcare worker vaccine hesitancy has used surveys and questionnaires giving a broad description of the prevalence and patterns of vaccine hesitancy in the healthcare workforce. This qualitative study examines vaccine behavior (rather than merely intent) through a cross comparison of healthcare workers' experiences and attitudes towards influenza and COVID-19 vaccination.How this study might affect research, practice or policy: Study findings can be used to help tailor vaccine messaging to hospital healthcare workers which could offset concerns regarding vaccine efficacy and risk, to promote vaccine uptake.

Examining the Influence of Historical Redlining on Firearm Injuries in Current Day Baltimore, Maryland.

Firearm injuries are a common and major public health problem in Baltimore, Maryland. The city is also one of the first U.S. cities in which the 1930s discriminatory practice of redlining first emerged. This study examines the association between current day firearm injuries and residence in these historically redlined areas at a neighborhood level using zip codes. Firearm injury outcomes in patients who presented to a hospital in Maryland from 2015 to 2020 were measured from the Health Services Cost Review Commission (HSCRC) in conjunction with both geospatial data from Richmond's Digital Scholarship Lab's Mapping Inequality project and population data from the U.S. Census. A redlining score was calculated to represent the extent of redlining in each zip code. Negative binomial regression models were utilized to measure the association between neighborhood zip codes and rate of firearm injuries. Our adjusted regression model shows that for every one-unit increase of the Home Owners' Loan Corporation (HOLC) redlining score, there is a 2.24-fold increase in the rate of firearm injuries (RR 2.24; 95% CI: 0.31, 1.31, p < 0.001). These findings suggest a strongassociation between historically redlined areas and population risk of firearm injury today. Further research is needed to investigate the underlying mechanisms that may contribute to this relationship, such as access to firearms or social and economic factors. Overall, our study highlights the potential impact of historical redlining policies on contemporary health outcomes in Baltimore.

Association of buprenorphine retention and subsequent adverse outcomes following non-fatal overdose: An analysis using statewide linked Maryland databases

IntroductionPatients receiving buprenorphine after a non-fatal overdose have lower risk of future nonfatal or fatal overdose, but less is known about the relationship between buprenorphine retention and the risk of adverse outcomes in the post-overdose year. ObjectiveTo examine the relationship between the total number of months with an active buprenorphine prescription (retention) and the odds of an adverse outcome within the 12 months following an index non-fatal overdose. Materials and methodsWe studied a cohort of people with an index non-fatal opioid overdose in Maryland between July 2016 and December 2020 and at least one filled buprenorphine prescription in the 12-month post-overdose observation period. We used individually linked Maryland prescription drug and hospital admissions data. Multivariable logistic regression models were used to examine buprenorphine retention and associated odds of experiencing a second non-fatal overdose, all-cause emergency department visits, and all-cause hospitalizations. ResultsOf 5439 people, 25% (n=1360) experienced a second non-fatal overdose, 78% had an (n=4225) emergency department visit, and 37% (n=2032) were hospitalized. With each additional month of buprenorphine, the odds of experiencing another non-fatal overdose decreased by 4.7%, all-cause emergency department visits by 5.3%, and all-cause hospitalization decreased by 3.9% (p<.0001, respectively). Buprenorphine retention for at least nine months was a critical threshold for reducing overdose risk versus shorter buprenorphine retention. ConclusionsBuprenorphine retention following an index non-fatal overdose event significantly decreases the risk of future overdose, emergency department use, and hospitalization even among people already on buprenorphine.

Telemedicine critical care availability and outcomes among mechanically ventilated patients

PurposeTelemedicine Critical Care (TCC) improves adherence to evidence based protocols associated with improved mortality among patients receiving invasive mechanical ventilation (IMV). We sought to evaluate the relationship between hospital availability of TCC and outcomes among patients receiving IMV. Materials and methodsWe performed a cross-sectional study of 66,522 adults who received IMV for non-postoperative acute respiratory failure at 318 non-federal hospitals in New York, Massachusetts, Maryland, and Florida in 2018. Hospital-level TCC availability was ascertained from the 2018 American Hospital Association Annual Survey. The primary outcome was in-hospital mortality. Secondary outcomes included the composite of tracheostomy or reintubation and duration of IMV. We used two-level hierarchical multivariable regression models to investigate the association between TCC availability and outcomes. Results20,270 (30.5%) patients were admitted into 89 TCC-available hospitals. There was no difference between TCC and non-TCC-available hospitals in mortality (odds ratio [OR] 0.94, 99% confidence interval [CI] 0.84–1.05), composite of tracheostomy or reintubation (OR 0.95 [0.82–1.11], or duration of IMV (OR 0.95 [0.83–1.09]). There was no difference in outcomes among the subgroup of patients with acute respiratory distress syndrome. ConclusionsHospital TCC availability was not associated with improved outcomes among patients receiving IMV.

Preparing the Frontlines: Delivering Special Pathogen Training to Maryland Hospital Staff.

Healthcare workers (HCWs) at community hospitals, also known as frontline hospitals (FLHs), may encounter patients with possible infectious diseases, including those caused by high-consequence pathogens such as Zaire ebolavirus. We created and piloted a 1-day, in-person, didactic and skills training program to determine the feasibility and acceptability of implementing an educational program to enhance the knowledge and skills needed to respond when a patient with a potential high-consequence pathogen presents to an FLH. The Maryland Department of Health queried all 104 state FLHs to identify their interest in participating in the pilot training program. HCWs from 12 (75%) of the 16 interested FLHs participated in the program before it was interrupted by the COVID-19 pandemic. In addition to pathogen-specific training based on the Identify, Isolate, and Inform framework, we provided skills training in the proper use of personal protective equipment, spill cleanup, and removal of an incapacitated HCW from an isolation area. We conducted a paired pretraining and posttraining knowledge assessment and measured a significant learning gain among 135 participants (2-tailed t test, P<.05). Over 95% of the participants reported that the training was relevant to their daily work and the clinical simulations and reference material were useful and appropriate for their learning level. Findings from this pilot program demonstrated the feasibility and acceptability of a 1-day combined didactic and skills training program focused on high-consequence pathogens. We plan to reengage the original FLHs and add regional FLHs in an updated training effort based on our findings.

Comparison of hospitalist morale in a COVID-19 alternate care site (ACS) to hospitalist morale in conventional hospitals in Maryland.

Morale and burnout were concerns for hospitalists prior to the COVID-19 pandemic; these concerns were amplified as COVID-19 spread and hospitals experienced unprecedented stress. In contrast to prior literature, our study assesses both satisfaction and the importance of various factors. This study examines morale of hospitalists early in the COVID-19 pandemic in two settings: conventional hospitals and a COVID-19 Alternate Care site (ACS) in the same geographic region in Maryland. Multiple studies published early in the pandemic show low morale in COVID-19 hospitals. In a cross-sectional survey study, we analyze data from the Hospitalist Morale Index (HMI) administered between September 2020 and March 2021 to determine the pandemic's impact on hospitalist morale. Surprisingly, our study found morale in the ACS was better than morale at the conventional hospitals. ACS hospitalists and conventional hospitalists were demographically similar. Our results show that a significantly higher proportion of conventional hospitalists reported burnout compared to the ACS hospitalists. General quality of life was rated significantly higher in the ACS group than the conventional group. Significantly more ACS hospitalists were invested in making their group outstanding. Five main HMI domains were examined with questions on a 5-point rating scale: Clinical Factors, Workload, Material Rewards, Leadership, and Appreciation/Acknowledgement. ACS hospitalists rated most measures higher than conventional hospitalists; largest differences were observed in Clinical Factors and Appreciation/Acknowledgement domains. Narrative comments from ACS hospitalists revealed strong identification with the mission of the ACS and pride in contributing during a crisis. One key difference between the two groups explains these findings: provider autonomy. The ACS staff chose the position and the assignment, while conventional hospitalists caring for COVID-19 patients could not readily opt out of this work. Our data suggest that autonomy in assignments with risk has implications for morale and burnout.

Multicentre genetic diversity study of carbapenem-resistant Enterobacterales: predominance of untypeable pUVA-like blaKPC bearing plasmids.

Carbapenem-resistant Enterobacterales (CRE) are an urgent public health threat. A better understanding of the molecular epidemiology and transmission dynamics of CRE is necessary to limit their dissemination within healthcare settings. We sought to investigate the mechanisms of resistance and spread of CRE within multiple hospitals in Maryland. From 2016 to 2018, all CRE were collected from any specimen source from The Johns Hopkins Medical Institutions. The isolates were further characterized using both phenotypic and genotypic approaches, including short- and/or long-read WGS. From 2016 to 2018, 302 of 40 908 (0.7%) unique Enterobacterales isolates were identified as CRE. Of CRE, 142 (47%) were carbapenemase-producing CRE with KPC (80.3%) predominating among various genera. Significant genetic diversity was identified among all CRE with high-risk clones serving as major drivers of clonal clusters. Further, we found the predominance of pUVA-like plasmids, with a subset harbouring resistance genes to environmental cleaning agents, involved in intergenus dissemination of blaKPC genes. Our findings provide valuable data to understand the transmission dynamics of all CRE within the greater Maryland region. These data can help guide targeted interventions to limit CRE transmission in healthcare facilities.

Is Obesity Driving the Increase in Young Stroke? (P6-5.002)

<h3>Objective:</h3> Our aim was to identify the association of obesity with young acute ischemic stroke (AIS), and the burden of lifestyle-related risk factors based on different body-mass-index (BMI) categories in patients with young AIS. <h3>Background:</h3> Obesity is a known risk factor for AIS in both the adult and young (&lt;50 years) population. Prior studies suggest that this association is mediated through risk factors such as diabetes and hypertension; however, the extent of this association has not been reported. <h3>Design/Methods:</h3> All patients with AIS, younger than 50 years, admitted to the University of Maryland hospital system hospitals Jan 2017 and December 2020, were included. Patients were categorized into 3 BMI categories: 1) Normal (18.5–24.9), 2) Overweight (25–29), and 3) Obese (≥30). Lifestyle-related risk factor (HTN, DM, DLD, and sleep apnea) burden and distribution was analyzed across the three groups using Chi-squared tests of association. One-way Welch’s ANOVA was utilized to test mean differences in number of risk factors across BMI categories. <h3>Results:</h3> We identified 1272 patients with young stroke. A total of 797/1272 (63%) of our young stroke patients were obese and 23.1% (n=294) were in the overweight category. In the obese category: mean age was 41.4 years (SD +/−6.75), 49.4% were women and 53.4% were Black. Risk factor burden was significantly higher in the obese vs. the overweight and normal weight categories (p = &lt;0.001). The proportion of patients with HTN, DM, DLD and sleep apnea was significantly higher in the obese category. <h3>Conclusions:</h3> A majority of young stroke patients were obese, and the obese and overweight patients were predominantly African American. Obese patients had the highest proportion of all medical risk factors, as well as a risk factor burden nearly twice as high as those with normal BMI. Efforts to reduce obesity hold promise in mitigating the burden of stroke in young adults. <b>Disclosure:</b> Dr. Solomonow has nothing to disclose. Karen Yarbrough has nothing to disclose.

Impact of Telehealth and Process Virtualization on Healthcare Utilization

Telehealth has emerged as a tool to improve patient access by virtualizing healthcare services, particularly during the COVID-19 pandemic. However, concerns have been raised that telehealth may actually increase healthcare spending by leading to new types of utilization. Our research provides empirical evidence that this concern is unfounded based on a state-wide study of patient visit-level data of telehealth use in 58 hospitals in Maryland from 2012 to 2021. On average, telehealth use can reduce future outpatient visits by 13.6% within 30 days after a telehealth visit, leading to a cost reduction of $239. The benefits of telehealth are most apparent for diseases with high potential for process virtualization, such as mental health, skin disorders, metabolic, and musculoskeletal diseases. Although telehealth has a substitution effect on future healthcare utilization, this effect is not observed among rural patients who use telehealth as a gateway to utilize more primary care and specialist services. Our findings suggest that policymakers should promote the use of telehealth in a value-based healthcare environment by providing monetary incentives to expand telehealth use among patients and providers, and expand the scope of telehealth services to include consultation with specialists especially among rural patients.

An Increase in the Use of ICD-10 Z-Codes for Social Risks and Social Needs: 2015 to 2019

Attention to 10th Revision of the International Classification of Disease (ICD-10)-CM Z-codes as a mechanism for capturing social risk has grown over the years. However, it remains unclear whether the use of Z-codes has changed over time. This study sought to examine the trends in Z-code use between their introduction in 2015 and the end of 2019 across 2 markedly different states. Using the Healthcare Cost and Utilization Project, all emergency department visits or hospitalizations at short-term general hospitals in Florida and Maryland from 2015 Q4 through 2019 were identified. This study focused on a subset of the Z-codes that are intended to capture social risk to identify the percentage of encounters with a Z-code, percentage of facilities using Z-codes, and facility median of number of encounters with a Z-code per 1000 encounters across quarters, states, and care settings. In total, 495,212 (0.84%) of 58,993,625 encounters had a Z-code. Despite Florida's higher area deprivation, Z-codes were less frequently used and increasing more slowly than when compared with those in Maryland. There were 2.1 times the use of Z-codes in Maryland than in Florida at the encounter level. This difference was also seen when evaluating the median number of encounters with a Z-code, per 1000 encounters (12.1 vs. 3.4). Z-codes were more commonly used at major teaching facilities, and for patients who were uninsured or on Medicaid. The use of ICD-10-CM Z-codes has increased over time, with this increase occurring at nearly all short-term general hospitals. Their use was higher in Maryland than in Florida and among major teaching facilities.

254: TELEMEDICINE CRITICAL CARE AVAILABILITY AND OUTCOMES AMONG MECHANICALLY VENTILATED PATIENTS

Introduction: Mechanical ventilation (MV) interventions like low tidal volume ventilation and daily spontaneous awakening and breathing trials are associated with improved survival but are unevenly implemented in real-world practice. Telemedicine Critical Care (TCC) improves adherence to these interventions. Whether or not hospitals with TCC have better MV outcomes than hospitals without TCC is unknown. We evaluated the association of hospital availability of TCC and outcomes among MV patients. Methods: We analyzed 19,679 adult non-surgical, mechanically ventilated patients in an Intensive Care Unit (ICU) in 2018 at 310 non-federal State Inpatient Database hospitals in Florida, Massachusetts, Maryland, and New York. The primary predictor variable was availability of TCC at a study hospital. The primary outcome was mortality defined as hospital death or discharge to hospice. Secondary outcomes were a composite of tracheostomy or re-intubation and duration of mechanical ventilation. We used a two-level hierarchical multivariable logistic regression model to investigate whether TCC availability was associated with study outcomes. Results: Among 19,679 mechanically ventilated patients, 6,177 (31.4%) occurred in TCC hospitals. Compared to non-TCC hospitals, TCC hospitals had reduced but insignificant odds of mortality (odds ratio [OR] 0.97, 95% CI 0.85–1.09), composite of tracheostomy/re-intubation (OR 0.93 [0.78–1.0]), and duration of mechanical ventilation (OR 0.95 [0.85-1.07]). Hospital size and annual mechanical ventilation case volume did not modify the association between TCC availability and mortality (P=0.75 and P=0.44 for interactions, respectively). Conclusions: Hospital availability of TCC was not associated with lower odds of mortality among mechanically ventilated patients.

Findings From Severe Maternal Morbidity Surveillance and Review in Maryland

In the US, more than 50 000 women experience severe maternal morbidity (SMM) each year, and the SMM rate more than doubled during the past 25 years. In response, professional organizations called for birthing facilities to routinely identify and review SMM events and identify prevention opportunities. To examine SMM levels, primary causes, and factors associated with the preventability of SMM using Maryland's SMM surveillance and review program. This cross-sectional study included pregnant and postpartum patients at 42 days or less after delivery who were hospitalized at 1 of 6 birthing hospitals in Maryland between August 1, 2020, and November 30, 2021. Hospital-based SMM surveillance was conducted through a detailed review of medical records. Hospitalization during pregnancy or within 42 days post partum. The main outcomes were admission to an intensive care unit, having at least 4 U of red blood cells transfused, and/or having COVID-19 infection requiring inpatient hospital care. A total of 192 SMM events were identified and reviewed. Patients with SMM had a mean [SD] age of 31 [6.49] years; 9 [4.7%] were Asian, 27 [14.1%] were Hispanic, 83 [43.2%] were non-Hispanic Black, and 68 [35.4%] were non-Hispanic White. Obstetric hemorrhage was the leading primary cause of SMM (83 [43.2%]), followed by COVID-19 infection (57 [29.7%]) and hypertensive disorders of pregnancy (17 [8.9%]). The SMM rate was highest among Hispanic patients (154.9 per 10 000 deliveries), primarily driven by COVID-19 infection. The rate of SMM among non-Hispanic Black patients was nearly 50% higher than for non-Hispanic White patients (119.9 vs 65.7 per 10 000 deliveries). The SMM outcome assessed could have been prevented in 61 events (31.8%). Clinician-level factors and interventions in the antepartum period were most frequently cited as potentially altering the SMM outcome. Practices that were performed well most often pertained to hospitals' readiness and adequate response to managing pregnancy complications. Recommendations for care improvement focused mainly on timely recognition and rapid response to such. The findings of this cross-sectional study, which used hospital-based SMM surveillance and review beyond the mere exploration of administrative data, offers opportunities for identifying valuable quality improvement strategies to reduce SMM. Immediate strategies to reduce SMM in Maryland should target its most common causes and address factors associated with preventability identified at individual hospitals.

Abstract 10255: The Evolving Impact of Myocardial Injury in COVID-19 Patient Amid the Omicron Wave of the Pandemic

Introduction: Coronavirus disease 2019 (COVID-19) with evidence of myocardial injury, defined as troponin elevation, has been demonstrated to be associated with worse outcomes. The temporal changes in outcomes in these patients during various phases of the pandemic remain unclear. Hypothesis: We sought to evaluate outcomes during the Omicron phase compared to previous phases of the pandemic. Methods: We analyzed COVID-19-positive patients with myocardial injury who presented to the MedStar Health system (11 hospitals in Washington, DC and Maryland) during Phase 1 of the pandemic (March 1 - June 30, 2020), Phase 2 (October 1, 2020 - January 31, 2021) and Phase 3 (Omicron) (December 1, 2021 - March 31, 2022) comparing their characteristics and outcomes. The primary end point was in-hospital mortality. Results: The cohort included 2079 COVID-19-positive admitted patients for whom troponin-I or high-sensitive troponin was elevated (Phase 1: n=150, Phase 2: n=854, Phase 3 [Omicron]: n=1075). Baseline characteristics were overall similar. Inflammatory markers were significantly elevated in Phase 1 as compared to Phase 2 and the Omicron Phase. The use of remdesivir and dexamethasone was most seen in Phase 2. In the Omicron Phase, 52.6% of patients were fully vaccinated. In-hospital mortality although high was lower in the Omicron Phase as compared to Phase 1 and Phase 2 (23.3% vs. 59.3% vs. 28.1%; p&lt;0.001). Those vaccinated demonstrated even more favorable outcomes as compared to those patients unvaccinated (18.3% vs 24.2%, p = 0.042). Conclusions: COVID-19 patients with elevated troponin during the Omicron Phase still have significant mortality rates despite overall improved outcomes when compared to the first and second waves of the pandemic. This improvement in outcomes could be attributed to the implementation of the COVID-19 vaccine, advances in available COVID-19 treatment options, provider experience with the novel disease and less virulent variants.

Is the Centralization of Complex Surgical Procedures an Unintended Spillover Effect of Global Capitation? - Insights from the Maryland Global Budget Revenue Program.

To determine if global budget revenue (GBR) models incent the centralization of complex surgical care. In 2014, Maryland initiated a statewide GBR model. While prior research has shown improvements in cost and outcomes for surgical care post-GBR implementation, the mechanism remains unclear. Utilizing state inpatient databases, we compared the proportion of adults undergoing elective complex surgeries (gastrectomy, pneumonectomy/lobectomy, proctectomies, and hip/knee revision) at high-concentration hospitals (HCHs) in Maryland and control states. Annual concentration, per procedure, was defined as hospital volume divided by state volume. HCHs were defined as hospitals with a concentration at least at the 75 th percentile in 2010. We estimated the difference-in-differences (DiD) of the probability of patients undergoing surgery at HCHs before and after GBR implementation. Our sample included 122,882 surgeries. Following GBR implementation, all procedures were increasingly performed at HCHs in Maryland. States satisfied the parallel trends assumption for the centralization of gastrectomy and pneumonectomy/lobectomy. Post-GBR, patients were more likely to undergo gastrectomy (DiD: 5.5 p.p., 95% CI [2.2, 8.8]) and pneumonectomy/lobectomy (DiD: 12.4 p.p., 95% CI [10.0, 14.8]) at an HCH in Maryland compared with control states. For our hip/knee revision analyses, we assumed persistent counterfactuals and noted a positive DiD post-GBR implementation (DiD: 4.8 p.p., 95% CI [1.3, 8.2]). No conclusion could be drawn for proctectomy due to different pre-GBR trends. GBR implementation is associated with increased centralization for certain complex surgeries. Future research is needed to explore the impact of centralization on patient experience and access.
