The association between community-level economic deprivation and incidences of emergency department visits on account of attempted suicides in Maryland.

Background: Suicide is a major cause of mortality in the United States, accounting for 14.5 deaths per 100,000 population. Many emergency department (ED) visits in the United States are due to attempted suicides. Suicide attempts predict subsequent completed suicides. Socioeconomic factors, such as community-level socioeconomic deprivation, significantly affect many traditional risk factors for attempted suicides and suicides. Aim: To determine the association between community-level socioeconomic deprivation and ED visits for attempted suicide in Maryland. Methods: A retrospective analysis of attempted suicides in the Maryland State Emergency Department Database from January 2018 to December 2020. Community-level socioeconomic deprivation was measured using the Distress Community Index (DCI). Multivariate regression analyses were conducted to identify the association between DCI and attempted suicides/self-harm. Results: There were 3,564,987 ED visits reported in the study period, with DCI data available for 3,236,568 ED visits; 86.8% were younger than 45 years, 64.8% were females, and 54.6% non-Hispanic Whites. Over the study period, the proportion of ED visits due to attempted suicide was 0.3%. In the multivariate logistic regression, compared to prosperous zones, those in comfortable (OR = 0.80, 95% CI: 0.73-0.88, p < 0.01), Mid-Tier (OR = 0.76, 95%CI:0.67-0.86, p < 0.01), At-Risk (OR = 0.77; 95%CI: 0.65-0.92, p < 0.01) and Distressed zones (OR = 0.53; 95% CI:0.42-0.66, p < 0.01) were less likely to visit the ED for attempted suicide. Conclusion: Prosperous communities had the highest rate of attempted suicides, with the risk of attempted suicide increasing as individuals move from the least prosperous to more prosperous areas.

Economic Burden of Inpatient Care for Mitral Regurgitation in Maryland.

BACKGROUND: Mitral regurgitation (MR) is the most common valvular disease in the United States and increases the risk of death and hospitalization. The economic burden of MR in the United States is not known. METHODS AND RESULTS: We analyzed inpatient hospitalization data from the 1 221 173 Maryland residents who had any in-state admissions from October 1, 2015, to September 30, 2019. We assessed the total charges for patients without MR and for patients with MR who underwent medical management, transcatheter mitral valve repair or replacement, or surgical mitral valve repair or replacement. During the study period, 26 076 inpatients had a diagnosis of MR. Compared with patients without MR, these patients had more comorbidities and higher inpatient mortality. Patients with medically managed MR incurred average total charges of $23 575 per year; MR was associated with $10 559 more in charges per year and an incremental 3.1 more inpatient days per year as compared with patients without MR. Both surgical mitral valve repair or replacement and transcatheter mitral valve repair or replacement were associated with higher charges as compared with medical management during the year of intervention ($47 943 for surgical mitral valve repair or replacement and $63 108 for transcatheter mitral valve repair or replacement). Annual charges for both groups were significantly lower as compared with medical management in the second and third years postintervention. CONCLUSIONS: MR is associated with higher mortality and inpatient charges. Patients who undergo surgical or transcatheter intervention incur lower charges compared with medically managed MR patients in the years after the procedure.

Increasing Injury Intensity among 6,500 Violent Deaths in the State of Maryland.

BACKGROUND: Anecdotal evidence strongly suggests there has been a rise in violent crimes. This study sought to examine trends in injury characteristics of homicide victims in Maryland. We hypothesized that there would be an increase in the severity of wound characteristics. STUDY DESIGN: The Office of the Chief Medical Examiner is a statewide agency designated by law to investigate all homicides, suicides, or unusual or suspicious circumstances. Using individual autopsy reports, we collected data among all homicides from 2005 to 2017, categorizing them into 3 time periods: 2005 to 2008 (early), 2009 to 2013 (mid), and 2014 to 2017 (late). Primary outcomes included the number of gunshots, stabs, and fractures from assaults. High-violence intensity outcomes included victims having 10 or more gunshots, 5 or more stabs, or 5 or more fractures from assaults. RESULTS: Of 6,500 homicides (annual range 403 to 589), the majority were from firearms (75%), followed by stabbings (14%) and blunt assaults (10%). Most homicide victims died in the hospital (60%). The average number of gunshots per victim was 3.9 (range 1 to 54), stabs per victim was 9.4 (range 1 to 563), and fractures from assaults per victim was 3.7 (range 0 to 31). The proportion of firearm victims with at least 10 gunshots nearly doubled from 5.7% in the early period to 10% (p < 0.01) in the late period. Similarly, the proportion with 5 or more stabbings increased from 39% to 50% (p = 0.02) and assault homicides with 5 or more fractures increased from 24% to 38% (p < 0.01). CONCLUSIONS: In Maryland, the intensity of violence increased across all major mechanisms of homicide. Further follow-up studies are needed to elucidate the root causes underlying this escalating trend.

Increased incidence of vibriosis in Maryland, U.S.A., 2006-2019.

BACKGROUND: Vibrio spp. naturally occur in warm water with moderate salinity. Infections with non-cholera Vibrio (vibriosis) cause an estimated 80,000 illnesses and 100 fatalities each year in the United States. Climate associated changes to environmental parameters in aquatic ecosystems are largely promoting Vibrio growth, and increased incidence of vibriosis is being reported globally. However, vibriosis trends in the northeastern U.S. (e.g., Maryland) have not been evaluated since 2008. METHODS: Vibriosis case data for Maryland (2006-2019; n = 611) were obtained from the COVIS database. Incidence rates were calculated using U.S. Census Bureau population estimates for Maryland. A logistic regression model, including region, age group, race, gender, occupation, and exposure type, was used to estimate the likelihood of hospitalization. RESULTS: Comparing the 2006-2012 and 2013-2019 periods, there was a 39% (p = 0.01) increase in the average annual incidence rate (per 100,000 population) of vibriosis, with V. vulnificus infections seeing the greatest percentage increase (53%, p = 0.01), followed by V. parahaemolyticus (47%, p = 0.05). The number of hospitalizations increased by 58% (p = 0.01). Since 2010, there were more reported vibriosis cases with a hospital duration ≥10 days. Patients from the upper eastern shore region and those over the age of 65 were more likely (OR = 6.8 and 12.2) to be hospitalized compared to other patients. CONCLUSIONS: Long-term increases in Vibrio infections, notably V. vulnificus wound infections, are occurring in Maryland. This trend, along with increased rates in hospitalizations and average hospital durations, underscore the need to improve public awareness, water monitoring, post-harvest seafood interventions, and environmental forecasting ability.

Effects of the First Year of the COVID-19 Pandemic on Utilization of Emergency Medical Services in Maryland.

BACKGROUND: The opioid epidemic in the United States has devastated the lives of individuals and imposed decades-long opportunity costs on the community. METHODS: We analyzed Emergency Medical Services (EMS) data from the Maryland Department of Health installation of the Electronic Surveillance System for Early Notification of Community-Based Epidemics (ESSENCE) to assess the impact of COVID-19 on EMS call volume and how COVID-19 impacted patients' decisions whether to accept transport to a hospital following an EMS call. RESULTS: The rate of patients accepting transportation via EMS to a hospital emergency department (ED) declined for both opioid-related and non-opioid-related calls from prepandemic (before April 2020) to mid-pandemic (mid-March 2020 to mid-April 2020). The opioid-related call volume increased more from pre- to mid-pandemic for male patients than for female patients, and this "gender gap" had not returned to prepandemic levels by April 2021. CONCLUSION: Consistent with reports from other states, the pandemic worsened the opioid crisis in Maryland, impacting some populations more than others while also decreasing the likelihood that individuals experiencing an opioid-related overdose would seek further medical care following an EMS call.

The physician gender pay gap in Maryland: current state and future directions.

BACKGROUND: Over the last few decades, more attention has been paid to the physician gender pay gap and more interventions have been attempted. This paper discusses the physician gender pay gap between 2017 and 2021 in Maryland. METHODS: An online cross-sectional survey was distributed to over 10,000 physicians in the Maryland Medical Society, featuring questions regarding employment characteristics, compensation, impact of the COVID-19 pandemic, and educational debt. Using descriptive and regression analyses, we explored cross-sectional associations between gender and employment characteristics. RESULTS: Male physicians reported a significantly higher average 2020 pre-tax income ($333,732 per year) than female physicians ($225,473 per year, p < 0.001), amounting to a nearly 50% difference in raw income, consistent with a previously reported pay gap in 2016. Women physicians earned 31.5% less than their male colleagues in 2020 and were projected to earn 28.7% less in 2021. Female physicians were also more likely to have educational debt (33.6% vs.12.9%, p < 0.001) and also more likely to have a high burden of debt, with 36% owing over $200,000 in education loans, compared to 14.7% of men (p < 0.01). CONCLUSION: The physician gender pay gap in Maryland has remained relatively stable over four years, including the period of the COVID-19 pandemic.

The physician gender pay gap in Maryland has remained stable over four years, including the period of the COVID-19 pandemic.Female physicians earned over 30% less than male physicians in Maryland in 2020.Female physicians are more likely to have educational debt, and when they do, they have a greater magnitude of debt.

Prevalence of Acinetobacter baumannii and Candida auris in Patients Receiving Mechanical Ventilation.

Importance: To date, only 1 statewide prevalence survey has been performed for Acinetobacter baumannii (2009) in the US, and no statewide prevalence survey has been performed for Candida auris, making the current burden of these emerging pathogens unknown. Objective: To determine the prevalence of A baumannii and C auris among patients receiving mechanical ventilation in Maryland. Design, Setting, and Participants: The Maryland Multi-Drug Resistant Organism Prevention Collaborative performed a statewide cross-sectional point prevalence of patients receiving mechanical ventilation admitted to acute care hospitals (n = 33) and long-term care facilities (n = 18) between March 7, 2023, and June 8, 2023. Surveillance cultures (sputum, perianal, arm/leg, and axilla/groin) were obtained from all patients receiving mechanical ventilation. Sputum, perianal, and arm/leg cultures were tested for A baumannii and antibiotic susceptibility testing was performed. Axilla/groin cultures were tested by polymerase chain reaction for C auris. Main Outcomes and Measures: Prevalence of A baumannii, carbapenem-resistant A baumannii (CRAB), and C auris. Prevalence was stratified by type of facility. Results: All 51 eligible health care facilities (100%) participated in the survey. A total of 482 patients receiving mechanical ventilation were screened for A baumannii and 470 were screened for C auris. Among the 482 patients who had samples collected, 30.7% (148/482) grew A baumannii, 88 of the 148 (59.5%) of these A baumannii were CRAB, and C auris was identified in 31 of 470 (6.6%). Patients in long-term care facilities were more likely to be colonized with A baumannii (relative risk [RR], 7.66 [95% CI, 5.11-11.50], P < .001), CRAB (RR, 5.48 [95% CI, 3.38-8.91], P < .001), and C auris (RR, 1.97 [95% CI, 0.99-3.92], P = .05) compared with patients in acute care hospitals. Nine patients (29.0%) with cultures positive for C auris were previously unreported to the Maryland Department of Health. Conclusions: A baumannii, carbapenem-resistant A baumannii, and C auris were common among patients receiving mechanical ventilation in both acute care hospitals and long-term care facilities. Both pathogens were significantly more common in long-term care facilities than in acute care hospitals. Patients receiving mechanical ventilation in long-term care facilities are a high-risk population for emerging pathogens, and surveillance and prevention efforts should be targeted to these facilities.

Pandemic detention: life with COVID-19 behind bars in Maryland.

Background: People incarcerated during the COVID-19 pandemic face higher vulnerability to infection due to structural and social factors in carceral settings. Additionally, due to the higher prevalence of chronic health conditions among carceral populations, they are also at risk for more severe COVID-19 disease. This study was designed to explore the experiences of people incarcerated in prisons and jails in Maryland during the height of the pandemic. Methods: We conducted semi-structured phone interviews between January 2021 and April 2022 with ten individuals incarcerated in Maryland carceral facilities during the height of the U.S. COVID-19 pandemic and were subsequently released from prison or jail. We transcribed the interviews, coded them, and engaged in content analysis, an inductive analytical approach to developing themes and meaning from qualitative data. Results: Four themes emerged from participants' descriptions of their experiences: (1) distress from fear, vulnerability, and lack of knowledge about COVID-19 and how to protect themselves, (2) shortcomings of prison and jail administrators and other personnel through lack of transparency and arbitrary and punitive enforcement of COVID-19 protocols, (3) lack of access to programming and communication with others, and (4) absence of preparation for release and access to usual re-entry services. Conclusion: Participants responded that the prison and jails' response during the COVID-19 pandemic was ill-prepared, inconsistent, and without appropriate measures to mitigate restrictions on liberty and prepare them for release. The lack of information sharing amplified their sense of fear and vulnerability unique to their incarceration status. Study findings have several institutional implications, such as requiring carceral facilities to establish public health preparedness procedures and making plans publicly available.

Outpatient visits before and after Lyme disease diagnosis in a Maryland employer-based health plan.

BACKGROUND: Insurance claims data have been used to inform an understanding of Lyme disease epidemiology and cost of care, however few such studies have incorporated post-treatment symptoms following diagnosis. Using longitudinal data from a private, employer-based health plan in an endemic US state, we compared outpatient care utilization pre- and post-Lyme disease diagnosis. We hypothesized that utilization would be higher in the post-diagnosis period, and that temporal trends would differ by age and gender. METHODS: Members with Lyme disease were required to have both a corresponding ICD-9 code and a fill of an antibiotic indicated for treatment of the infection within 30 days of diagnosis. A 2-year 'pre- diagnosis' period and a 2-year 'post-diagnosis period' were centered around the diagnosis month. Lyme disease-relevant outpatient care visits were defined as specific primary care, specialty care, or urgent care visits. Descriptive statistics examined visits during these pre- and post-diagnosis periods, and the association between these periods and the number of visits was explored using generalized linear mixed effects models adjusting for age, season of the year, and gender. RESULTS: The rate of outpatient visits increased 26% from the pre to the post-Lyme disease diagnosis periods among our 317-member sample (rate ratio = 1.26 [1.18, 1.36], p < 0.001). Descriptively, care utilization increases appeared to persist across months in the post-diagnosis period. Women's care utilization increased by 36% (1.36 [1.24, 1.50], p < 0.001), a significantly higher increase than the 14% increase found among men (1.14 [1.02, 1.27], p = 0.017). This gender difference was mainly driven by adult members. We found a borderline significant 17% increase in visits for children < 18 years, (1.17 [0.99, 1.38], p = 0.068), and a 31% increase for adults ≥ 18 years (1.31 [1.21, 1.42], p < 0.001). CONCLUSIONS: Although modest at the population level, the statistically significant increases in post-Lyme diagnosis outpatient care we observed were persistent and unevenly distributed across demographic and place of service categories. As Lyme disease cases continue to grow, so will the cumulative prevalence of persistent symptoms after treatment. Therefore, it will be important to confirm these findings and understand their significance for care utilization and cost, particularly against the backdrop of other post-acute infectious syndromes.

The association between severe maternal morbidity and mortality and race/ethnicity with community type in Maryland.

BACKGROUND: Severe maternal morbidity and mortality are increasing in the United States with continued healthcare disparities among Non-Hispanic Black women. However, there is sparse data on the disparities of severe maternal morbidity and mortality by race/ethnicity as it relates to community type. OBJECTIVE: To determine whether residing in rural communities increases the racial/ethnic disparities in severe maternal morbidity and mortality. DESIGN: This study is a cross-sectional analysis of women admitted for delivery from 2015 to 2020. A total of 204,140 adults who self-identified as women, were admitted for delivery, who resided in Maryland, and were between the ages 15 and 54 were included in our analysis. Community type was defined as either rural or urban. METHODS: A multivariable logistic regression, which included an interaction term between race/ethnicity and community type, was used to assess the effect of community type on the relationship between race/ethnicity and severe maternal morbidity and mortality. Data were obtained from the Maryland Health Service Cost Review Commission database. The primary outcome was a composite, binary variable of severe maternal morbidity and mortality. Exposures of interest were residence in either rural or urban counties in Maryland and race/ethnicity. RESULTS: Our study found that after adjusting for confounders, odds of severe maternal morbidity and mortality were 65% higher in Non-Hispanic Black women (odds ratio 1.65, 95% confidence interval: 1.46-1.88, p < 0.001) and 54% higher in Non-Hispanic Asian women (odds ratio 1.54, 95% confidence interval: 1.24-1.90, p < 0.001) compared to Non-Hispanic White women. The interaction term used to determine whether community type modified the relationship between race/ethnicity and severe maternal morbidity and mortality was not statistically significant for any race/ethnicity (Non-Hispanic Black women, p = 0.60; Non-Hispanic Asian women, p = 0.91; Hispanic women, p = 0.15; Other/Unknown race/ethnicity, p = 0.54). CONCLUSION: Although our study confirmed the known disparities in maternal outcomes by race/ethnicity, we found that residing in rural communities did not increase racial/ethnic disparities.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: Our data suggest that autonomy in assignments with risk has implications for morale and burnout.

The Distressed Communities Index: A Measure of Community-Level Economic Deprivation and Rate of Firearm Injuries in Maryland.

BACKGROUND: This study aimed to investigate the relationship between community-level economic deprivation, as measured by the Distressed Communities Index (DCI) and ED visits on account of firearm injuries (assaults and unintentional). METHODS: A retrospective analysis was conducted using the Maryland State Emergency Department Databases (SEDD) from January 2019 to December 2020 to explore the association between the DCI and ED visits because of firearm injuries (assaults and unintentional). The DCI utilizes 7 variables, based on zip codes, generating 5 levels of socioeconomic distress (prosperous, comfortable, mid-tier, at-risk, and distressed). In a multivariate analysis, we adjusted for age, sex, mental conditions, alcohol addiction, substance abuse, smoking, race/ethnicity, insurance type, and median income. RESULTS: Of the 2725 ED visits for firearm injuries, 84.5% were Black and 88.5% male. The median age was 27 (21-35) years, and the mortality rate was 17.7%. A statistically significant association was found between economic deprivation and ED visits for firearm injuries. Compared to prosperous communities, the odds ratios (ORs) were comfortable (OR = 1.33, 95% CI 1.04-1.71, P = .03), mid-tier (OR = 1.69, 95% CI 1.33-2.15, P < .001), at-risk (OR = 1.53, 95% CI 1.17-1.99, P < .001), and distressed (OR = 2.65, 95% CI 2.11-3.33, P < .001). DISCUSSION: The study highlights the significant association between community-level economic deprivation, as measured by the Distressed Communities Index, and the incidence of firearm injuries in Maryland. The findings underscore the importance of addressing socioeconomic disparities and implementing targeted interventions to reduce firearm-related injuries in economically distressed communities.

Screening for Social Determinants of Health Among Medicare Beneficiaries in Primary Care During the Covid-19 Pandemic in Prince George's County, Maryland.

Primary care providers in Prince George's County, Maryland reported inconsistencies in their ability to identify and refer patients with social care needs. This project aimed to improve health outcomes of Medicare beneficiaries by implementing social determinant of health (SDOH) screening to identify unmet needs and improve rates of referral to appropriate services. Buy-in was achieved from providers and frontline staff via stakeholder meetings at a private primary care group practice. The Health Leads questionnaire was modified and integrated into the electronic health record. Medical assistants (MA) were trained to conduct screening and initiate care plan referrals prior to visits with the medical provider. During implementation, 96.25% of patients (n = 231) agreed to screening. Of these, 13.42% (n = 31) screened positive for at least one SDOH need, and 48.39% (n = 15) reported multiple social needs. Top needs included social isolation (26.23%), literacy (16.39%), and financial concerns (14.75%). All patients screening positive for one or more social needs were provided referral resources. Patients who identified as being of Mixed or Other race had significantly higher rates of positive screens (p = 0.032) compared to Caucasians, African Americans, and Asians. Patients were more likely to report SDOH needs during in-person visits (17.22%) compared to telehealth visits (p = 0.020). Screening for SDOH needs is feasible and sustainable and can improve the identification of SDOH needs and resource referrals. A limitation of this project was the lack of follow-up to determine whether patients with positive SDOH screens had been successfully linked to resources after initial referral.

The Maryland (USA) Critical Care Coordination Center (C4): From Pandemic to Permanence.

INTRODUCTION: The 2019 coronavirus disease (COVID-19) pandemic created overwhelming demand for critical care services within Maryland's (USA) hospital systems. As intensive care units (ICUs) became full, critically ill patients were boarded in hospital emergency departments (EDs), a practice associated with increased mortality and costs. Allocation of critical care resources during the pandemic requires thoughtful and proactive management strategies. While various methodologies exist for addressing the issue of ED overcrowding, few systems have implemented a state-wide response using a public safety-based platform. The objective of this report is to describe the implementation of a state-wide Emergency Medical Services (EMS)-based coordination center designed to ensure timely and equitable access to critical care. METHODS: The state of Maryland designed and implemented a novel, state-wide Critical Care Coordination Center (C4) staffed with intensivist physicians and paramedics purposed to ensure appropriate critical care resource management and patient transfer assistance. A narrative description of the C4 is provided. A retrospective cohort study design was used to present requests to the C4 as a case series report to describe the results of implementation. RESULTS: Providing a centralized asset with regional situational awareness of hospital capability and bed status played an integral role for directing the triage process of critically ill patients to appropriate facilities during and after the COVID-19 pandemic. A total of 2,790 requests were received by the C4. The pairing of a paramedic with an intensivist physician resulted in the successful transfer of 67.4% of requests, while 27.8% were managed in place with medical direction. Overall, COVID-19 patients comprised 29.5% of the cohort. Data suggested increased C4 usage was predictive of state-wide ICU surges. The C4 usage volume resulted in the expansion to pediatric services to serve a broader age range. The C4 concept, which leverages the complimentary skills of EMS clinicians and intensivist physicians, is presented as a proposed public safety-based model for other regions to consider world-wide. CONCLUSION: The C4 has played an integral role in the State of Maryland's pledge to its citizens to deliver the right care to the right patient at the right time and can be considered as a model for adoption by other regions world-wide.

A Saliva-Based Serological and Behavioral Analysis of SARS-CoV-2 Antibody Prevalence in Howard County, Maryland.

The objective of the study was to estimate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence in the Howard County, Maryland, general population and demographic subpopulations attributable to natural infection or coronavirus disease 2019 (COVID-19) vaccination and to identify self-reported social behaviors that may affect the likelihood of recent or past SARS-CoV-2 infection. A cross-sectional, saliva-based serological study of 2,880 residents of Howard County, Maryland, was carried out from July through September 2021. Natural SARS-CoV-2 infection prevalence was estimated by inferring infections among individuals according to anti-nucleocapsid immunoglobin G levels and calculating averages weighted by sample proportions of various demographics. Antibody levels between BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) recipients were compared. Antibody decay rate was calculated by fitting exponential decay curves to cross-sectional indirect immunoassay data. Regression analysis was carried out to identify demographic factors, social behaviors, and attitudes that may be linked to an increased likelihood of natural infection. The estimated overall prevalence of natural infection in Howard County, Maryland, was 11.9% (95% confidence interval, 9.2% to 15.1%), compared with 7% reported COVID-19 cases. Antibody prevalence indicating natural infection was highest among Hispanic and non-Hispanic Black participants and lowest among non-Hispanic White and non-Hispanic Asian participants. Participants from census tracts with lower average household income also had higher natural infection rates. After accounting for multiple comparisons and correlations between participants, none of the behavior or attitude factors had significant effects on natural infection. At the same time, recipients of the mRNA-1273 vaccine had higher antibody levels than those of BNT162b2 vaccine recipients. Older study participants had overall lower antibody levels compared with younger study participants. The true prevalence of SARS-CoV-2 infection is higher than the number of reported COVID-19 cases in Howard County, Maryland. A disproportionate impact of infection-induced SARS-CoV-2 positivity was observed across different ethnic/racial subpopulations and incomes, and differences in antibody levels across different demographics were identified. Taken together, this information may inform public health policy to protect vulnerable populations. IMPORTANCE We employed a highly innovative noninvasive multiplex oral fluid SARS-CoV-2 IgG assay to ascertain our seroprevalence estimates. This laboratory-developed test has been applied in NCI's SeroNet consortium, possesses high sensitivity and specificity according to FDA Emergency Use Authorization guidelines, correlates strongly with SARS-CoV-2 neutralizing antibody responses, and is Clinical Laboratory Improvement Amendments-approved by the Johns Hopkins Hospital Department of Pathology. It represents a broadly scalable public health tool to improve understanding of recent and past SARS-CoV-2 exposure and infection without drawing any blood. To our knowledge, this is the first application of a high-performance salivary SARS-CoV-2 IgG assay to estimate population-level seroprevalence, including identifying COVID-19 disparities. We also are the first to report differences in SARS-CoV-2 IgG responses by COVID-19 vaccine manufacturers (BNT162b2 [Pfizer-BioNTech] and mRNA-1273 [Moderna]). Our findings demonstrate remarkable consistency with those of blood-based SARS-CoV-2 IgG assays in terms of differences in the magnitude of SARS-CoV-2 IgG responses between COVID-19 vaccines.

Rapid Analysis of Drugs: A Pilot Surveillance System To Detect Changes in the Illicit Drug Supply To Guide Timely Harm Reduction Responses - Eight Syringe Services Programs, Maryland, November 2021-August 2022.

A record number of 2,912 drug overdose deaths occurred in Maryland during the 12-month period July 1, 2020-June 30, 2021. Illicitly manufactured fentanyl, fentanyl analogs, or both* were involved in 84% of these deaths.† Timely identification of illicit drug market changes (e.g., fentanyl rapidly replacing heroin) could improve the public health response, specifically communications about risks for novel psychoactive substances. During November 19, 2021-August 31, 2022, the National Institute of Standards and Technology (NIST)§ tested 496 deidentified drug paraphernalia samples that staff members collected at eight Maryland syringe services programs (SSPs), also known as needle exchange programs,¶ in partnership with the Maryland Department of Health Center for Harm Reduction Services (CHRS).** All test results were available within 48 hours. Among the 496 paraphernalia samples collected, 367 (74.0%) tested positive for an opioid, and 364 (99.2%) of these samples contained fentanyl or fentanyl analogs. Approximately four fifths of fentanyl-positive samples also tested positive for the veterinary medicine xylazine, a sedative that when combined with opioids might increase the potential for fatal respiratory depression and soft tissue infections when injected (1). For 248 of the 496 samples, SSP participants also completed a questionnaire about the drugs they had intended to purchase. Among the 212 participants who had intended to buy an opioid, 87.7% were exposed to fentanyl, fentanyl analogs, or both, and 85.8% were unknowingly exposed to xylazine. Results improved awareness of fentanyl and xylazine among SSP staff members and galvanized efforts to enhance SSPs' wound care services for participants experiencing soft tissue injuries possibly associated with injecting xylazine. Rapid analysis of drug paraphernalia can provide timely data on changing illicit drug markets that can be used to mitigate the harms of drug use more effectively.

The Impact of the COVID-19 Pandemic on the Experiences and Operations of Sponsors of the Summer Food Service Program in Maryland, USA: A Multiphase Mixed Methods Study.

During the COVID-19 pandemic, the Summer Food Service Program (SFSP) was allowed to operate in untraditional non-summer months to ensure children did not lose access to free and reduced-priced nutritious meals when schools were mandated to close in the United States. This study assessed the impact of the pandemic on the operations and experiences of Summer Food Service Program (SFSP) sponsors in the state of Maryland during the COVID-19 pandemic in 2020 (Phase I) and 2021 (Phase II). This study used a multiphase explanatory sequential mixed methods design with qualitative prioritization. Maryland SFSP sponsors completed an online survey (Phase I: n = 27, Phase II: n = 30), and semi-structured in-depth interviews were conducted with a subset of sponsors who completed the survey (Phase I: n = 12, Phase II: n = 7). Inductive and deductive analyses were used for qualitative data, and descriptive statistics were used for quantitative data. The COVID-19 pandemic caused SFSP sponsors to change their operations. Sponsors were primarily concerned about staff safety/burnout and decreased participation. Sponsors perceived waivers implemented by the United States Department of Agriculture to be crucial in enabling them to serve meals to children during the pandemic. The findings from our study support advocacy efforts to permanently implement waivers and provide free school meals for all children.

Emergency department utilization and disposition outcomes by pediatric patients with cancer in Maryland and New York from 2013 to 2017.

BACKGROUND: Pediatric patients with cancer commonly seek emergency department (ED) care, yet there is limited evidence on ED utilization patterns and disposition outcomes among these patients. METHODS: Retrospective analysis of the Healthcare Cost and Utilization Project State Emergency Department Databases and State Inpatient Databases for Maryland and New York from 2013 to 2017. We compared ED visits and disposition outcomes for 5.8 million pediatric patients (<18 years old) with and without cancer, and used multivariable regressions to estimate associations between the number of ED visits, hospital (inpatient) admissions through the ED, and ED or inpatient mortality and sociodemographic and clinical factors within the cancer cohort. RESULTS: Pediatric patients with cancer had more ED visits per year on average (2.4 vs. 1.5, p < .001), higher shares of admissions (56.8% vs. 6.6%, p < .001) and mortality (1.2% vs. 0.1%, p < .001) compared to those without cancer. Among patients with cancer, uninsured pediatric patients had fewer ED visits and lower risk of admission to a hospital through the ED compared to those with Medicaid coverage (total visits: incidence rate ratio [IRR]: 0.82, 95% confidence intervals [CI]: 0.75-0.90; admission: IRR: 0.75, 95% CI: 0.65-0.86). Mortality risks were higher for pediatric patients with cancer residing in areas with the lowest median household income, and with no health insurance coverage (IRR: 2.81, 95% CI: 1.21-6.51) compared to Medicaid. CONCLUSIONS: Our findings emphasize the importance of enhancing health insurance coverage policies and social services for pediatric patients with cancer and their families to address clinical and nonclinical needs.
