An assessment of the linkages between GM crop biotechnology and climate change mitigation.

This article provides an analysis and evaluation of peer-reviewed evidence on the contribution of crop biotechnology to climate change mitigation and adaption. While there is a range of agricultural technologies and products that contribute to climate change mitigation, this literature landscape analysis focuses on the development of genetically modified traits, their use and adoption in major commodity crops and responsive changes in production techniques. Jointly, these technologies and products are contributing to climate change mitigation, yet the technology, the literature and evidence is still evolving as more sophisticated research methods are used with greater consistency. The literature analysis is undertaken with consideration of the consequential impact that regulatory regimes have on technology development. This assessment utilizes the Maryland Scientific Methods Scale and citation analysis, concluding that GM crops provide benefits that contribute to climate change mitigation.

Understanding social needs screening and demographic data collection in primary care practices serving Maryland Medicare patients.

BACKGROUND: Health outcomes are strongly impacted by social determinants of health, including social risk factors and patient demographics, due to structural inequities and discrimination. Primary care is viewed as a potential medical setting to assess and address individual health-related social needs and to collect detailed patient demographics to assess and advance health equity, but limited literature evaluates such processes. METHODS: We conducted an analysis of cross-sectional survey data collected from n = 507 Maryland Primary Care Program (MDPCP) practices through Care Transformation Requirements (CTR) reporting in 2022. Descriptive statistics were used to summarize practice responses on social needs screening and demographic data collection. A stepwise regression analysis was conducted to determine factors predicting screening of all vs. a targeted subset of beneficiaries for unmet social needs. RESULTS: Almost all practices (99%) reported conducting some form of social needs screening and demographic data collection. Practices reported variation in what screening tools or demographic questions were employed, frequency of screening, and how information was used. More than 75% of practices reported prioritizing transportation, food insecurity, housing instability, financial resource strain, and social isolation. CONCLUSIONS: Within the MDPCP program there was widespread implementation of social needs screenings and demographic data collection. However, there was room for additional supports in addressing some challenging social needs and increasing detailed demographics. Further research is needed to understand any adjustments to clinical care in response to identified social needs or application of data for uses such as assessing progress towards health equity and the subsequent impact on clinical care and health outcomes.

Interstate Highway Connections and Traced Gun Transfers Between the 48 Contiguous United States.

Importance: Interstate gun flow has critical implications for gun violence prevention, as gun transfers across state lines can undermine local gun control policies. Objective: To identify possible gun trafficking routes along interstate highways in the US. Design, Setting, and Participants: This repeated-measures, ecological, cross-sectional study used data from the Bureau of Alcohol, Tobacco, Firearms and Explosives from January 1, 2010, to December 31, 2019, to examine associations between interstate connections via 13 highways that each spanned at least 1000 miles and interstate traced gun transfer counts for the 48 contiguous United States. Analyses were completed in November 2023. Exposures: Characteristics of the origin states and the transportation connections between the destination state and the origin states. Main Outcomes and Measures: The main outcome was the total count of guns used in crimes in each destination state per year that were originally purchased in the origin state. Bayesian conditional autoregressive Poisson models were used to examine associations between the count of guns used in crime traced to interstate purchases and interstate highway connections between origin and destination states. Results: Between 2010 and 2019, 526 801 guns used in crimes in the contiguous 48 states were traced to interstate purchases. Northbound gun transfers along the Interstate 95 corridor were greater than expected to New Jersey (incidence rate ratio [IRR], 2.80; 95% credible interval [CrI], 1.01-7.68) and Maryland (IRR, 3.07; 95% CrI, 1.09-8.61); transfers were similarly greater along Interstate 15 southbound, Interstate 25 southbound, Interstate 35 southbound, Interstate 75 northbound and southbound, Interstate 10 westbound, and Interstate 20 eastbound and westbound. Conclusions and Relevance: This repeated-measures, ecological, cross-sectional study identified that guns used in crimes traced to interstate purchases moved routinely between states along multiple major transportation routes. Interstate gun transfers are a major contributor to gun crime, injury, and death in the US. National policies and interstate cooperation are needed to address this issue.

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

INTRODUCTION: Patients 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. OBJECTIVE: To 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 METHODS: We 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. RESULTS: Of 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. CONCLUSIONS: Buprenorphine 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.

Maryland School Health partners' Perspectives on the Impact of COVID-19 on School Health Services for Grades K-12.

BACKGROUND: The COVID-19 pandemic disrupted routine school operations, including school health programs. This study aims to describe the pandemic's impact on school health service delivery from the perspective of Maryland school health partners. METHODS: We conducted semi-structured interviews with health service representatives from public schools (K-12) between July and December 2021. Interviews were recorded, transcribed, and coded through an iterative process to develop analytic themes. RESULTS: Twenty school health partners from 15 Maryland school districts participated. Participants identified key impacts of COVID-19 on school health: (1) COVID-19 disrupted delivery of services such as dental, mental health, and preventative care, (2) COVID-19 necessitated changes in service delivery platforms, (3) COVID-19 affected school health staff through increased responsibilities and staffing shortages, and (4) COVID-19 prompted schools to become hubs for community outreach and health education. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Consideration of school health service disruptions and the increased demands on service providers may inform future priorities for school administrators, health departments, and policymakers. CONCLUSIONS: COVID-19 impacted the timing and method of service delivery as well as the roles of school health staff and schools themselves in public health and education.

Tobacco smoking and nicotine vaping in persons with first episode psychosis.

Tobacco smoking is highly prevalent in persons with psychosis and is the leading cause of preventable mortality in this population. Less is known about tobacco smoking in persons with first episode psychosis (FEP) and there have been no estimates about the prevalence of nicotine vaping in FEP. This study reports rates of tobacco smoking and nicotine vaping in young people with FEP enrolled in Coordinated Specialty Care programs in Pennsylvania and Maryland. Using data collected from 2021 to 2023, we examined lifetime and recent smoking and vaping and compared smokers and vapers to nonusers on symptoms, functioning, and substance use. The sample included 445 participants aged 13-35 with recent psychosis onset. Assessments were collected by program staff. Overall, 28 % of participants engaged in either smoking or vaping within 30 days of the admission assessment. Smokers and vapers were disproportionately male, cannabis users, and had lower negative symptom severity than non-smokers. Vapers had higher role and social functioning. Both smoking and vaping were related to a longer time from psychosis onset to program enrollment. We compare these findings to previous studies and suggest steps for addressing smoking and vaping in this vulnerable population.

Susceptibility of shellfish aquaculture species in the Chesapeake Bay and Maryland coastal bays to ostreid herpesvirus 1 microvariants.

Ostreid herpesvirus 1 (OsHV-1) and its microvariants (µVars) cause economically devastating mass mortalities of oysters and pose a threat to the shellfish aquaculture industry globally. OsHV-1 outbreaks can cause up to 100% mortality in the Pacific oyster Crassostrea gigas. However, OsHV-1 and its variants have a broad host range and can infect at least 7 bivalve species, including bay scallops Argopecten irradians and eastern oysters C. virginica. Determining the susceptibility of economically and ecologically important bivalve species to OsHV-1 is critical for improving biosecurity and disease management to protect the aquaculture industry. Surveys of eastern oysters were conducted in June to August 2021 in the Maryland portion of the Chesapeake Bay to determine the prevalence and viral load of OsHV-1 at 5 aquaculture farms. Using quantitative PCR, OsHV-1 was not detected at any sites. Experiments examined the susceptibility of single stocks of eastern oysters and hard clams Mercenaria mercenaria to the virus and their ability to horizontally transmit it using OsHV-1 µVar SD (San Diego, California) and OsHV-1 µVar FRA (Marennes-Olreon, France). Results showed that OsHV-1 µVars did not cause mortality or symptomatic infection in the single stocks of eastern oysters and hard clams used in these experiments using natural infection pathways. However, the eastern oyster stock, when injected with OsHV-1, did transmit the virus to naïve Pacific oysters. Further experimentation using additional stocks and lines and establishment of surveillance programs along the east and Gulf coasts of the USA are necessary to prepare for the potential spread and impact of OsHV-1 related disease.

Nutrient reduction by eastern oysters exhibits low variability associated with reproduction, ploidy, and farm location.

Enhancement of shellfish populations has long been discussed as a potential nutrient reduction tool, and eastern oyster aquaculture was recently approved as a nutrient reduction best management practice (BMP) in Chesapeake Bay, USA. This study addressed BMP-identified data gaps involving variation in nutrient concentration related to ploidy, effects of reproductive development, and a paucity of phosphorus concentration data. Diploid and triploid oysters were collected from farms in Maryland and Virginia across the typical local reproductive cycle. The nutrient concentration of tissue and shell was consistent with the currently implemented BMP. Minor variation observed in nitrogen and phosphorus concentration was within the previously reported range, for farm location, ploidy, and reproductive cycle timing. Ploidy-based differences in tissue dry weight were not observed at either farm, which contrasts with current nutrient reduction estimates. These results suggest separate crediting values for diploids and triploids may need further investigation and potential re-evaluation.

Postpartum long-acting reversible contraceptive adoption after a statewide initiative.

OBJECTIVES: To examine the effects of a comprehensive, multiyear (2015-2020) statewide contraceptive access intervention in Delaware on the contraceptive initiation of postpartum Medicaid patients. The program aimed to increase access to all contraceptives, including long-acting reversible contraceptives (LARC). The program included interventions specifically targeting postpartum patients (Medicaid payment reform and hospital-based immediate postpartum (IPP) LARC training) and interventions in outpatient settings (provider training and operational supports). DATA SOURCES AND STUDY SETTING: We used Medicaid claims data between 2012 and 2019, from Delaware and Maryland (a comparison state), to identify births and postpartum contraceptive methods up to 60 days postpartum among patients aged 15-44 years who were covered in a full-benefit eligibility category. STUDY DESIGN: Using difference-in-differences, we assessed changes in LARC, tubal ligation, and short-acting methods (oral contraceptive, injectable, patch/ring). LARC rates were assessed at 60 days after delivery and on an immediate postpartum basis. Other methods were only assessed at 60 days. Analyses were conducted separately for an early-adopting high-capacity hospital (that delivers approximately half of all Medicaid financed births) and for all other later-adopting hospitals in the state. DATA COLLECTION/EXTRACTION METHODS: Data were extracted from administrative claims. PRINCIPAL FINDINGS: The program increased postpartum LARC insertions by 60 days after delivery by 11.7 percentage points (95% CI: 10.7, 12.8) in the early-adopting hospital and 6.9 percentage points (95% CI: 4.8, 5.9) in later-adopting hospitals. Increases in IPP versus outpatient LARC drove the change, but we did not find evidence that IPP crowded-out outpatient LARC services. We observed decreases in short-acting methods, suggesting substitution between methods, but the share of patients with any method increased at the early-adopting hospital (5.2 percentage points; 95% CI: 3.5, 6.9) and was not statistically significantly different at the later-adopting hospitals. CONCLUSIONS: Direct reimbursement for IPP LARC, in combination with provider training, had a meaningful impact on the share of Medicaid-enrolled postpartum women with LARC claims.

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.

Geographic source of bats killed at wind-energy facilities in the eastern United States.

Bats subject to high rates of fatalities at wind-energy facilities are of high conservation concern due to the long-term, cumulative effects they have, but the impact on broader bat populations can be difficult to assess. One reason is the poor understanding of the geographic source of individual fatalities and whether they constitute migrants or more local individuals. Here, we used stable hydrogen isotopes, trace elements and species distribution models to determine the most likely summer geographic origins of three different bat species (Lasiurus borealis, L. cinereus, and Lasionycteris noctivagans) killed at wind-energy facilities in Ohio and Maryland in the eastern United States. In Ohio, 41.6%, 21.3%, 2.2% of all individuals of L. borealis, L. cinereus, and L. noctivagans, respectively, had evidence of movement. In contrast, in Maryland 77.3%, 37.1%, and 27.3% of these same species were classified as migrants. Our results suggest bats killed at a given wind facility are likely derived from migratory as well as resident populations. Finally, there is variation in the proportion of migrants killed between seasons for some species and evidence of philopatry to summer roosts. Overall, these results indicate that the impact of wind-energy facilities on bat populations occurs across a large geographic extent, with the proportion of migrants impacted likely to vary across species and sites. Similar studies should be conducted across a broader geographic scale to understand the impacts on bat populations from wind-energy facilities.

Xylazine-Associated Wounds and Related Health Concerns Among People Who Use Drugs: Reports From Front-Line Health Workers in 7 US States.

BACKGROUND: Xylazine, an adrenergic alpha-2 agonist increasingly present in the US drug supply, is associated with severe skin ulcers and other harms. Expert knowledge from front-line harm reduction and healthcare professionals is an essential component of evidence-based practice. The purpose of this study is to describe the progression and treatment of xylazine-associated wounds, other xylazine-related health concerns, and the most urgent research priorities as reported by front-line harm reduction and healthcare professionals serving people who use drugs. METHODS: A convenience sample of 17 healthcare and harm reduction professionals who serve people who use drugs in the US states of Maryland, Massachusetts, Michigan, Minnesota, North Carolina, Pennsylvania, and Texas participated in semi-structured interviews. Participants were asked about the appearance and progression of xylazine-associated wounds; preferred treatment strategies; other xylazine-related harms experienced by people who use drugs; and the most urgent priorities for xylazine-related research. FINDINGS: Xylazine-associated wounds were broadly described as small lesions appearing mostly on extremities both at and away from injection sites, often within hours or days of exposure, that quickly developed into large, complex, chronic wounds. Reported risk of secondary infection was generally low but appeared more common among unhoused populations. Most participants preferred conservative treatment strategies that included regular wound care, enzymatic debridement, and hygiene. Xylazine-associated wounds and xylazine withdrawal reportedly act as significant barriers to care, including addiction treatment. Participants reported urgent need for scientific research and evidence-based guidance on the management of xylazine-associated wounds and withdrawal. CONCLUSIONS: High-quality scientific evidence on risk factors for xylazine-associated wounds and on their biologic mechanisms is needed. Such studies could inform new strategies for the prevention and treatment of these wounds. Efforts to improve the management of xylazine withdrawal and to reduce stigma by incorporating harm reduction professionals into healthcare settings may improve access to and retention in care.

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.

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.

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 effect of Section 1557 of the Affordable Care Act on surgical outcomes in non-English primary language speakers.

BACKGROUND: In 2016, Section 1557 mandated use of qualified language interpreter services. We examined the effect of Section 1557 on surgical outcomes. METHODS: Utilizing the Healthcare Cost and Utilization Project State Inpatient Database (2013-2020), we performed a difference-in-differences analysis of adult surgical patients (Maryland, New Jersey). The exposure was implementation of Section 1557 (pre-period: 2013-2015; post-period: 2017-2020). The treatment group was non-English primary language speakers (n-EPL). The comparison group was English primary language speakers (EPL). Outcomes included length-of-stay, postoperative complications, mortality, discharge disposition, and readmissions. RESULTS: Among 2,298,584 patients, 198,385 (8.6%) were n-EPL. After implementation of Section 1557, n-EPL saw no difference in readmission rates but did experience significantly higher rates of mortality (+0.43%, p â€‹= â€‹0.049) and non-routine discharges (+1.81%, p â€‹= â€‹0.031) in Maryland, and higher rates of post-operative complications (+0.31%, p â€‹= â€‹0.001) in both states, compared to pre-Section 1557. CONCLUSIONS: Contrary to our hypothesis, Section 1557 did not improve surgical outcomes for n-EPL.
