Pregnancy Termination Policy and Cleft Lip and Palate.

BACKGROUND: Restrictive policies on termination of pregnancy (TOP) may lead to more infants with congenital abnormalities. This study aims to assess the association between state-wide enactment of TOP restriction and cleft lip and/or palate (CL/P) incidence and identify mediating demographic characteristics. METHODS: This study examines state-specific trends in CL/P incidence in infants before and after implementing laws restricting TOP in MI compared to NY, where no such laws were passed. The percent change of CL/P incidence per 1000 live births in post-policy years (2012-2015) compared to pre-policy years (2005-2011) was compared while adjusting for confounding factors in multivariate models. RESULTS: The incidence of CL/P changed significantly in MI (19.1%) versus NY (-7.31%). Adjusting for sex, race/ethnicity, median household income level, and expected payer revealed that the adjusted percent difference between MI and NY was 53.3% (p <0.001). Stratification by race/ethnicity and median household income demonstrated that changes were only significant amongst Black (139%, p<0.001) and Hispanic (125%, p=0.045) patients or of those from the lowest (50.3%, p<0.001) and second lowest (40.1%, p=0.01) income quartiles. CONCLUSIONS: Our research, combined with the recent Dobbs Supreme Court decision allowing states to place further restrictions on TOP, suggests that more infants in the future will be born in need of treatment for CL/P.

The PRIDx framework to engage payers in reducing diagnostic errors in healthcare.

OBJECTIVES: No framework currently exists to guide how payers and providers can collaboratively develop and implement incentives to improve diagnostic safety. We conducted a literature review and interviews with subject matter experts to develop a multi-component 'Payer Relationships for Improving Diagnoses (PRIDx)' framework, that could be used to engage payers in diagnostic safety efforts. CONTENT: The PRIDx framework, 1) conceptualizes diagnostic safety links to care provision, 2) illustrates ways to promote payer and provider engagement in the design and adoption of accountability mechanisms, and 3) explicates the use of data analytics. Certain approaches suggested by PRIDx were refined by subject matter expert interviewee perspectives. SUMMARY: The PRIDx framework can catalyze public and private payers to take specific actions to improve diagnostic safety. OUTLOOK: Implementation of the PRIDx framework requires new types of partnerships, including external support from public and private payer organizations, and requires creation of strong provider incentives without undermining providers' sense of professionalism and autonomy. PRIDx could help facilitate collaborative payer-provider approaches to improve diagnostic safety and generate research concepts, policy ideas, and potential innovations for engaging payers in diagnostic safety improvement activities.

Food Environments Within and Outside of Schools Play a Critical Role in Curtailing the Rise in Obesity among School-Aged Children over Time.

BACKGROUND: Sound evidence for effective community-based strategies is needed to curtail upward trends in childhood obesity in the United States (US). OBJECTIVES: The aim of the study was to assess the association between school and community food environments and the prevalence of obesity over time. METHODS: Data were collected from K-12 schools in 4 low-income New Jersey cities in the US. School-level obesity prevalence, calculated from nurse-measured heights and weights at 4 time points, was used as the outcome variable. Data on the school food environment (SFE) measured the healthfulness of school lunch and competitive food offerings annually. The community food environment (CFE), i.e., the number of different types of food outlets within 400 m of schools, was also captured annually. The count and presence of food outlets likely to be frequented by students were calculated. Exposure to composite environment profiles both within schools and in communities around schools was assessed using latent class analysis. Data from 106 schools were analyzed using multilevel linear regression. RESULTS: The prevalence of obesity increased from 25% to 29% over the course of the study. Obesity rates were higher in schools that had nearby access to a greater number of limited-service restaurants and lower in schools with access to small grocery stores and upgraded convenience stores participating in initiatives to improve healthful offerings. Interaction analysis showed that schools that offered unhealthier, competitive foods experienced a faster increase in obesity rates over time. Examining composite food environment exposures, schools with unhealthy SFEs and high-density CFEs experienced a steeper time trend (ß = 0.018, P < 0.001) in obesity prevalence compared to schools exposed to healthy SFE and low-density CFEs. CONCLUSIONS: Food environments within and outside of schools are associated with differential obesity trajectories over time and can play an important role in curtailing the rising trends in childhood obesity.

Persistent Disparities in Access to Elective Colorectal Cancer Surgery After Medicaid Expansion Under the Affordable Care Act: A Multistate Evaluation.

BACKGROUND: Despite their higher incidence of colorectal cancer, ethnoracial minority and low-income patients have reduced access to elective colorectal cancer surgery. Although the Affordable Care Act's Medicaid expansion increased screening of colonoscopies, its effect on disparities in elective colorectal cancer surgery remains unknown. OBJECTIVE: This study assessed the effects of Medicaid expansion on elective colorectal cancer surgery rates overall and by race-ethnicity and income. DESIGN: Using the 2012 to 2015 State Inpatient Databases, a retrospective cohort study was conducted. SETTINGS: State Inpatient Databases from 3 expansion states (Maryland, New Jersey, and Kentucky) and 2 nonexpansion states (Florida and North Carolina) were used. PATIENTS: This study examined 22,304 adult patients aged 18 to 64 years who underwent colorectal cancer surgery. MAIN OUTCOME MEASURES: Using interrupted time series analysis, the effect of Medicaid expansion on the odds of elective colorectal cancer surgery was assessed. RESULTS: Elective vs nonelective surgery rates remained unchanged overall (70.2% vs 70.7%, p = 0.63) and in ethnoracial minorities in expansion states (whites from 72.8% to 73.8% pre to post, p = 0.40 and non-white from 64.0% to 63.1% pre to post, p = 0.67). There was an instantaneous increase in odds of elective surgery in expansion vs nonexpansion states at policy implementation (adjusted OR 1.37; 95% CI, 1.05-1.79; p = 0.02), but it subsequently decreased (combined adjusted OR 0.95; 95% CI, 0.92-0.99; p = 0.03). Elective surgery rates were also unchanged among ethnoracial minorities (instantaneous changes in expansion states, combined effect 1.06; pre-trend 1.01 vs post-trend 0.98) and low-income persons in expansion states (pre-trend 1.03 vs post-trend 0.97) (for all, p > 0.1). LIMITATIONS: The study was limited to 5 states. Although patients may have increased access to cancer screening services and surgery after expansion, the State Inpatient Databases only provide information on patients who underwent surgery. CONCLUSIONS: Despite gains in screening, Medicaid expansion was not associated with reductions in known ethnoracial or income-based disparities in elective colorectal cancer surgery rates. Expanding access to colorectal cancer surgery for underserved populations likely requires attention to provider and health system factors contributing to persistent disparities.

DISPARIDADES PERSISTENTES EN EL ACCESO A LA CIRUGA ELECTIVA DEL CNCER COLORRECTAL DESPUS DE LA EXPANSIN DE MEDICAID EN VIRTUD DE LA LEY DEL CUIDADO DE SALUD A BAJO PRECIO UNA EVALUACIN MULTIESTATAL: ANTECEDENTES: A pesar de su mayor incidencia de cáncer colorrectal, los pacientes de minorías etnoraciales y de bajos ingresos tienen un acceso reducido a la cirugía electiva de cáncer colorrectal. Aunque la expansión de Medicaid de la Ley del Cuidado de Salud a Bajo Precio aumentó las colonoscopias de detección, aún se desconoce su efecto sobre las disparidades en la cirugía electiva de cáncer colorrectal.OBJETIVO: Este estudio evaluó los efectos de la expansión de Medicaid en las tasas de cirugía electiva de cáncer colorrectal en general y por raza, etnia e ingresos.DISEÑO: Utilizando las bases de datos estatales de pacientes hospitalizados de 2012-2015, se realizó un estudio de cohorte retrospectivo.CONFIGURACIÓN: Se utilizaron bases de datos estatales de pacientes hospitalizados de tres estados en expansión (Maryland, Nueva Jersey, Kentucky) y dos estados sin expansión (Florida, Carolina del Norte).PACIENTES: Este estudio examinó a 22,304 pacientes adultos de 18 a 64 años que se sometieron a cirugía de cáncer colorrectal.RESULTADO PRINCIPAL: Mediante el análisis de series de tiempo interrumpido, se evaluó el efecto de la expansión de Medicaid en las probabilidades de cirugía electiva de cáncer colorrectal.RESULTADOS: Las tasas de cirugía electiva frente a no electiva permanecieron sin cambios en general (70,2% frente a 70,7%, p = 0,63) y en las minorías etnoraciales en los estados de expansión (blancos del 72,8% al 73,8 % antes y después, p = 0,40 y no blancos del 64,0% al 63,1% pre a post, p = 0,67). Hubo un aumento instantáneo en las probabilidades de cirugía electiva en los estados de expansión frente a los de no expansión en la implementación de la política (OR ajustado 1,37, IC del 95%, 1,05-1,79, p = 0,02), pero disminuyó posteriormente (OR ajustado combinado 0,95, 95% IC, 0,92-0,99, p = 0,03). Las tasas de cirugía electiva también se mantuvieron sin cambios entre las minorías etnoraciales (cambios instantáneos en los estados de expansión, efecto combinado 1,06; antes de la tendencia 1,01 frente a la postendencia 0,98) y las personas de bajos ingresos en los estados de expansión (antes de la tendencia 1,03 frente a la postendencia 0,97; para todos, p > 0,1).LIMITACIONES: El estudio se limitó a cinco estados. Si bien los pacientes pueden tener un mayor acceso a los servicios de detección de cáncer y la expansión posterior a la cirugía, la base de datos de pacientes hospitalizados del estado solo brinda información sobre los pacientes que se sometieron a cirugía.CONCLUSIONES: A pesar de los avances en la detección, la expansión de Medicaid no se asoció con reducciones en las disparidades etnoraciales o basadas en los ingresos conocidas en las tasas de cirugía electiva de cáncer colorrectal. Ampliar el acceso a la cirugía del cáncer colorrectal para las poblaciones desatendidas probablemente requiera atención a los factores del proveedor y del sistema de salud que contribuyen a las disparidades persistentes.

Health, social, and economic characteristics of patients enrolled in a COVID-19 recovery program.

At least one in five people who recovered from acute COVID-19 have persistent clinical symptoms, however little is known about the impact on quality-of-life (QOL), socio-economic characteristics, fatigue, work and productivity. We present a cross-sectional descriptive characterization of the clinical symptoms, QOL, socioeconomic characteristics, fatigue, work and productivity of a cohort of patients enrolled in the MedStar COVID Recovery Program (MSCRP). Our participants include people with mental and physical symptoms following recovery from acute COVID-19 and enrolled in MSCRP, which is designed to provide comprehensive multidisciplinary care and aid in recovery. Participants completed medical questionnaires and the PROMIS-29, Fatigue Severity Scale, Work and Productivity Impairment Questionnaire, and Social Determinants of Health surveys. Participants (n = 267, mean age 47.6 years, 23.2% hospitalized for COVID-19) showed impaired QOL across all domains assessed with greatest impairment in physical functioning (mean 39.1 ± 7.4) and fatigue (mean 60.6 ±. 9.7). Housing or "the basics" were not afforded by 19% and food insecurity was reported in 14% of the cohort. Participants reported elevated fatigue (mean 4.7 ± 1.1) and impairment with activity, work productivity, and on the job effectiveness was reported in 63%, 61%, and 56% of participants, respectively. Patients with persistent mental and physical symptoms following initial illness report impairment in QOL, socioeconomic hardships, increased fatigue and decreased work and productivity. Our cohort highlights that even those who are not hospitalized and recover from less severe COVID-19 can have long-term impairment, therefore designing, implementing, and scaling programs to focus on mitigating impairment and restoring function are greatly needed.

Impact of Clinician Linkage on Unequal Access to High-Volume Hospitals for Colorectal Cancer Surgery.

BACKGROUND: Understanding drivers of persistent surgical disparities remains an important area of cancer care delivery and policy. The degree to which clinician linkages contribute to disparities in access to quality colorectal cancer surgery is unknown. Using hospital surgical volume as a proxy for quality, the study team evaluated how clinician linkages impact access to colorectal cancer surgery at high-volume hospitals (HVHs). STUDY DESIGN: Maryland's Health Services Cost Review Commission was used to evaluate 6,909 patients who underwent colon or rectal cancer operations from 2013 to 2018. Two linkages based on patient sharing were examined separately for colon and rectal cancer surgery: (1) from primary care clinicians to specialists (gastroenterologist or medical oncologist) and (2) from specialists to surgeons (general or colorectal). A referral link was defined as 9 or more shared patients between 2 clinicians. Adjusted regression models examined associations between referral links and odds of receiving colon or rectal cancer operations at HVHs. RESULTS: The cohort included 5,645 colon and 1,264 rectal cancer patients across 52 hospitals. Every additional referral link between a primary care clinician and a specialist connected to a HVH was associated with a 12% and 14% increased likelihood of receiving colon (odds ratio [OR] 1.12, CI 1.07 to 1.17) and rectal (OR 1.14, CI 1.08 to 1.20]) cancer operations at a HVH, respectively. Every additional referral link between a specialist and a surgeon at a HVH was associated with at least a 25% increased likelihood of receiving colon (OR 1.28, CI 1.20 to 1.36) and rectal (OR 1.25, CI 1.15 to 1.36) cancer operation at a HVH. CONCLUSIONS: Patients of clinicians with linkages to HVHs are more likely to have their colorectal cancer operations at these hospitals. These findings suggest that policy interventions targeting clinician relationships are an important step in providing equitable surgical care.

A Focus on Amputation Level: Factors Preventing Length Preservation in the National Inpatient Sample.

BACKGROUND: Diabetic lower-extremity disease is the primary driver of mortality in patients with diabetes. Amputations at the forefoot or ankle preserve limb length, increase function, and, ultimately, reduce deconditioning and mortality compared with higher-level amputations, such as below-the-knee amputations (BKAs). We sought to identify risk factors associated with amputation level to understand barriers to length-preserving amputations (LPAs). METHODS: Diabetic lower-extremity admissions were extracted from the 2012-2014 National Inpatient Survey using ICD-9-CM diagnosis codes. The main outcome was a two-level variable consisting of LPAs (transmetatarsal, Syme, and Chopart) versus BKAs. Logistic regression analysis was used to determine contributions of patient- and hospital-level factors to likelihood of undergoing LPA versus BKA. RESULTS: The study cohort represented 110,355 admissions nationally: 42,375 LPAs and 67,980 BKAs. The population was predominantly white (56.85%), older than 50 years (82.55%), and male (70.38%). On multivariate analysis, living in an urban area (relative risk ratio [RRR] = 1.48; P < .0001) and having vascular intervention in the same hospital stay (RRR = 2.96; P < .0001) were predictive of LPA. Patients from rural locations but treated in urban centers were more likely to receive BKA. Minorities were more likely to present with severe disease, limiting delivery of LPAs. A high Elixhauser comorbidity score was related to BKA receipt. CONCLUSIONS: This study identifies delivery biases in amputation level for patients without access to large, urban hospitals. Rural patients seeking care in these centers are more likely to receive higher-level amputations. Further examination is required to determine whether earlier referral to multidisciplinary centers is more effective at reducing BKA rates versus satellite centers in rural localities.

Effects of Maryland's global budget revenue model on emergency department utilization and revisits.

BACKGROUND: In 2014, Maryland (MD) implemented a "global budget revenue" (GBR) program that prospectively sets hospital budgets. This program introduced incentives for hospitals to tightly control volume and meet budget targets. We examine GBR's effects on emergency department (ED) visits, admissions, and returns. METHODS: We performed an interrupted time-series analysis with difference-in-differences comparisons using 2012 to 2015 Healthcare Cost Utilization and Project data from MD, New York (NY), and New Jersey (NJ). We examined GBR's effects on ED visits/1,000 population, admissions from the ED, and ED returns at 72 h and 9 days. We also examined rates of admission, intensive care unit (ICU) stay, and in-hospital mortality among returns. To evaluate racial/ethnic and payer outcome disparities among ED returns, we performed a triple differences analysis. RESULTS: ED visits decreased with GBR adoption in MD relative to NY and NJ, by five and six visits/1,000 population, respectively. ED admissions declined relative to NY and NJ, by 0.6% and 1.8%, respectively. There was also a post-GBR decline in ED returns by 0.7%. Admissions among returns declined by 2%, while ICU and in-hospital mortality among returns remained relatively stable. ED return outcomes varied by racial/ethnic and payer group. Non-Hispanic Whites and non-Hispanic Blacks experienced a similar decline in returns, while returns remained unchanged among Hispanics/Latinos, widening the disparity gap. Payer group disparities between privately insured and Medicare, Medicaid, and uninsured individuals improved, with the disparity reduction most pronounced among the uninsured. CONCLUSIONS: GBR adoption was associated with lower ED utilization and admissions. ED returns and admissions among returns also decreased, while mortality and ICU stays among returns remained stable, suggesting that GBR has not led to adverse patient outcomes from fewer admissions. However, changes in ED return disparities varied by subgroup, indicating that improvements in care transitions may be uneven across patient populations.

Differential Associations Between Changes in Food Environment and Changes in BMI Among Adults Living in Urban, Low-Income Communities.

BACKGROUND: Food environments can contribute to excess weight gain among adults, but the evidence is mixed. OBJECTIVES: This longitudinal study investigated the associations between changes in the food environment and changes in BMI in adults and whether changes in the food environment differentially impact various subgroups. METHODS: At 2 time points, BMI was calculated using self-reported height and weight data from 517 adults (mean age, 41 years) living in 4 New Jersey cities. The counts of different types of food outlets within 0.4, 0.8, and 1.6 km of respondents' residences were collected at baseline and tracked until follow-up. A binary measure of social standing (social-advantage group, n = 219; social-disadvantage group, n = 298) was created through a latent class analysis using social, economic, and demographic variables. Multivariable linear regression modeled the associations between changes in BMI with measures of the food environment; additionally, interaction terms between the measures of food environment and social standing were examined. RESULTS: Overall, over 18 months, an increase in the number of small grocery stores within 0.4 km of a respondent's residence was associated with a decrease in BMI (ß = -1.0; 95% CI: -1.9, -0.1; P = 0.024), while an increase in the number of fast-food restaurants within 1.6 km was associated with an increase in BMI (ß = 0.1; 95% CI: 0.01, 0.2; P = 0.027). These overall findings, however, masked some group-specific associations. Interaction analyses suggested that associations between changes in the food environment and changes in BMI varied by social standing. For instance, the association between changes in fast-food restaurants and changes in BMI was only observed in the social-disadvantage group (ß = 0.1; 95% CI: 0.02, 0.2; P = 0.021). CONCLUSIONS: In a sample of adults living in New Jersey, changes in the food environment had differential effects on individuals' BMIs, based on their social standing.

ACA Medicaid expansion reduced disparities in use of high-volume hospitals for pancreatic surgery.

BACKGROUND: Early evaluation of the Affordable Care Act's Medicaid expansion demonstrated persistent disparities among Medicaid beneficiaries in use of high-volume hospitals for pancreatic surgery. Longer-term effects of expansion remain unknown. This study evaluated the impact of expansion on the use of high-volume hospitals for pancreatic surgery among Medicaid and uninsured patients. METHODS: State inpatient databases (2012-2017), the American Hospital Association Annual Survey Database, and the Area Resource File from the Health Resources and Services Administration, were used to examine 8,264 non-elderly adults who underwent pancreatic surgery in nine expansion and two non-expansion states. High-volume hospitals were defined as performing 20 or more resections/year. Linear probability triple differences models measured pre- and post-Affordable Care Act utilization rates of pancreatic surgery at high-volume hospitals among Medicaid and uninsured patients versus privately insured patients in expansion versus non-expansion states. RESULTS: The Affordable Care Act's expansion was associated with increased rates of utilization of high-volume hospitals for pancreatic surgery by Medicaid and uninsured patients (48% vs 55.4%, P = .047) relative to privately insured patients in expansion states (triple difference estimate +11.7%, P = .022). A pre-Affordable Care Act gap in use of high-volume hospitals among Medicaid and uninsured patients in expansion states versus non-expansion states (48% vs 77%, P < .0001) was reduced by 15.1% (P = .001) post Affordable Care Act. A pre Affordable Care Act gap between expansion versus non-expansion states was larger for Medicaid and uninsured patients relative to privately insured patients by 24.9% (P < .0001) and was reduced by 11.7% (P = .022) post Affordable Care Act. Rates among privately insured patients remained unchanged. CONCLUSION: Medicaid expansion was associated with greater utilization of high-volume hospitals for pancreatic surgery among Medicaid and uninsured patients. These findings are informative to non-expansion states considering expansion. Future studies should target understanding referral mechanism post-expansion.

Effects of Permanent Supportive Housing on Health Care Utilization and Spending Among New Jersey Medicaid Enrollees Experiencing Homelessness.

BACKGROUND: Permanent supportive housing (PSH) programs have the potential to improve health and reduce Medicaid expenditures for beneficiaries experiencing homelessness. However, most research on PSH has been limited to small samples of narrowly defined populations. OBJECTIVE: To evaluate the effects of PSH on Medicaid enrollees across New Jersey. RESEARCH DESIGN: Linked data from the Medicaid Management Information System and the Homeless Management Information System were used to compare PSH-placed Medicaid enrollees with a matched sample of other Medicaid enrollees experiencing homelessness. Comparisons of Medicaid-financed health care utilization and spending measures were made in a difference-in-differences framework 6 quarters before and after PSH placement. SUBJECTS: A total of 1442 Medicaid beneficiaries enrolled in PSH and 6064 Medicaid-enrolled homeless individuals not in PSH in 2013-2014. RESULTS: PSH placement is associated with a 14.3% reduction in emergency department visits (P<0.001) and a 25.2% reduction in associated spending (P<0.001). PSH also appears to reduce inpatient utilization and increase pharmacy spending with neutral effects on primary care visits and total costs of care (TCOC). CONCLUSIONS: Placement in PSH is associated with lower hospital utilization and spending. No relationship was found, however, between PSH placement and TCOC, likely due to increased pharmacy spending in the PSH group. Greater access to prescription drugs may have improved the health of PSH-placed individuals in a way that reduced hospital episodes with neutral effects on TCOC.

Use of Flap Salvage for Lower Extremity Chronic Wounds Occurs Most Often in Competitive Hospital Markets.

Wounds in the comorbid population require limb salvage to prevent amputation. Extensive health economics literature demonstrates that hospital activities are influenced by level of market concentration. The impact of competition and market concentration on limb salvage remains to be determined. METHODS: Admissions for chronic lower extremity wounds in nonrural hospitals were identified in the 2010-2011 National Inpatient Survey using ICD-9-CM diagnosis codes. The study cohort consisted of admitted patients receiving amputations, salvage without flap techniques (eg, skin grafts), or salvage with flap techniques. The all-service Herfindahl-Hirschman Index (HHI), which is a commonly used tool for market and antitrust analyses, was used to measure hospital competition. Multinomial regression analysis accounting for the complex survey design of the NIS was used to determine the relationship between the HHI and hospital adoption of limb salvage controlling for patient, hospital, and market factors. RESULTS: The study cohort represents 124,836 admissions nationally: 89,880 amputations, 26,715 salvage without flap techniques, and 8241 salvage flap techniques. Diabetics accounted for 64.1% of all study admissions. Hospitals in highly competitive markets performed more flaps for chronic lower extremity wounds than noncompetitive markets. Controlling for other factors, hospitals in highly competitive markets, relative to those in highly concentrated markets, were 2.48 percentage points more likely to perform limb salvage with flaps (P < 0.01). Other factors were less predictive. CONCLUSION: Increased hospital competition is the strongest systems-level predictor of receipt of lower extremity flaps among patients with chronic wounds. Improving access to reconstructive limb services must consider the competitive structure of hospital markets.

Primary care for new vs established Medicaid enrollees.

OBJECTIVES: To understand changes in primary care (PC) utilization in Medicaid and the Children's Health Insurance Program (CHIP) 3 years after the Affordable Care Act (ACA). STUDY DESIGN: Secondary data analysis using Medicaid/CHIP paid claims and managed care encounters. METHODS: Pre-/post-ACA trends in total enrollment and PC visits among newly enrolled and established patients were analyzed in half-year increments from the first half of 2012 to the second half of 2016. RESULTS: After ACA expansion, there was a temporary surge in new Medicaid/CHIP enrollment (which included surges in pre-ACA eligibility categories) and slow, steady growth in total enrollment. The percentage of new enrollees completing a PC visit within 90, 180, and 365 days of enrollment fell markedly in the first half of 2014 and then rebounded to pre-ACA levels thereafter. Conversely, the percentage of new enrollees remaining enrolled at 90, 180, and 365 days spiked upward in the first half of 2014 and gradually fell thereafter. Among established enrollees, PC visits per person exhibited a downward trend throughout the post-ACA period, driven mostly by a decline in the percentage of individuals with any PC visits. CONCLUSIONS: The first 6 months of ACA implementation in New Jersey were marked by a surge in Medicaid/CHIP enrollment that extended beyond the ACA target population, greater enrollment retention, and apparent bottlenecks in PC delivery. After the initial surge, new enrollees used PC at rates at least as high as in the pre-ACA period, whereas established enrollees used PC at a declining rate throughout the post-ACA period. PC delivery for new enrollees may have limited the availability of services for some established enrollees.

Emergency department care coordination strategies and perceived impact under Maryland's hospital payment reforms.

BACKGROUND: Emergency department (ED) care coordination plays an important role in facilitating care transitions across settings. We studied ED care coordination processes and their perceived effectiveness in Maryland (MD) hospitals, which face strong incentives to reduce hospital-based care through global budgets. METHODS: We conducted a qualitative study using semi-structured interviews to examine ED care coordination processes and perceptions of effectiveness. Interviews were conducted from January through October 2019 across MD hospital-based EDs. Results were reviewed to assign analytic domains and identify emerging themes. Descriptive statistics of ED care coordination staffing and processes were also calculated. RESULTS: A total of 25 in-depth interviews across 18 different EDs were conducted with ED physician leadership (n = 14) and care coordination staff (CCS) (n = 11). Across all EDs, there was significant variation in the hours and types of CCS coverage and the number of initiatives implemented to improve care coordination. Participants perceived ED care coordination as effective in facilitating safer discharges and addressing social determinants of health; however, adequate access to outpatient providers was a significant barrier. The majority of ED physician leaders perceived MD's policy reform as having a mixed impact, with improved care transitions and overall patient care as benefits, but increased physician workloads and worsened ED throughput as negative effects. CONCLUSIONS: EDs have responded to the value-based care incentives of MD's global budgeting program with investments to enhance care coordination staffing and a variety of initiatives targeting specific patient populations. Although the observed care coordination initiatives were broadly perceived to produce positive results, MD's global budgeting policies were also perceived to produce barriers to optimizing ED care. Further research is needed to determine the association of the various strategies to improve ED care coordination with patient outcomes to inform practice leaders and policymakers on the efficacy of the various approaches.

Evidence That Changes in Community Food Environments Lead to Changes in Children's Weight: Results from a Longitudinal Prospective Cohort Study.

BACKGROUND: Strategies to improve the community food environment have been recommended for addressing childhood obesity, but evidence substantiating their effectiveness is limited. OBJECTIVE: Our aim was to examine the impact of changes in availability of key features of the community food environment, such as supermarkets, small grocery stores, convenience stores, upgraded convenience stores, pharmacies, and limited service restaurants, on changes in children's body mass index z scores (zBMIs). DESIGN: We conducted a longitudinal cohort study. PARTICIPANTS/SETTING: Two cohorts of 3- to 15-year-old children living in 4 low-income New Jersey cities were followed during 2- to 5-year periods from 2009 through 2017. Data on weight status were collected at 2 time points (T1 and T2) from each cohort; data on food outlets in the 4 cities and within a 1-mile buffer around each city were collected multiple times between T1 and T2. MAIN OUTCOME MEASURES: We measured change in children's zBMIs between T1 and T2. STATISTICAL ANALYSIS: Changes in the food environment were conceptualized as exposure to changes in counts of food outlets across varying proximities (0.25 mile, 0.5 mile, and 1.0 mile) around a child's home, over different lengths of time a child was exposed to these changes before T2 (12 months, 18 months, and 24 months). Multivariate models examined patterns in relationships between changes in zBMI and changes in the food environment. RESULTS: Increased zBMIs were observed in children with greater exposure to convenience stores over time, with a consistent pattern of significant associations across varying proximities and lengths of exposure. For example, exposure to an additional convenience store over 24 months within 1 mile of a child's home resulted in 11.7% higher odds (P = 0.007) of a child being in a higher zBMI change category at T2. Lower zBMIs were observed in children with increased exposure to small grocery stores selling an array of healthy items, with exposure to an additional small grocery store within 1 mile over 24 months, resulting in 37.3% lower odds (P < 0.05) of being in a higher zBMI change category at T2. No consistent patterns were observed for changes in exposure to supermarkets, limited service restaurants, or pharmacies. CONCLUSIONS: Increased availability of small grocery stores near children's homes may improve children's weight status, whereas increased availability of convenience stores is likely to be detrimental.

Who, What, Where: Demographics, Severity of Presentation, and Location of Treatment Drive Delivery of Diabetic Limb Reconstructive Services within the National Inpatient Sample.

BACKGROUND: Technical advances have been made in reconstructive diabetic limb salvage modalities. It is unknown whether these techniques are widely used. This study seeks to determine the role of patient- and hospital-level characteristics that affect use. METHODS: Admissions for diabetic lower extremity complications were identified in the 2012 to 2014 National Inpatient Sample using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes. The study cohort consisted of admitted patients receiving amputations, limb salvage without flap techniques, or advanced limb salvage with flap techniques. Multinomial regression analysis accounting for the complex survey design of the National Inpatient Sample was used to determine the independent contributions of factors expressed as marginal effects. RESULTS: The authors' study cohort represented 155,025 admissions nationally. White non-Hispanic patients had the highest proportion of reconstruction without and with flaps, whereas black patients had the lowest. Multinomial regression models revealed that controlling for nongas gangrene and critical limb ischemia, both of which have a much greater incidence in minorities, the effect of race against receipt of reconstructive modalities was attenuated. Access to urban teaching hospitals was the strongest protective factor against amputation (9 percent reduction; p < 0.01) and predictor of receiving limb salvage without flaps (5 percent increase; p < 0.01) and with flaps (3 percent increase; p < 0.01). CONCLUSIONS: This study identified multiple patient- and hospital-level factors associated with decreased access to the gamut of reconstructive limb salvage techniques. Disparity reduction will likely require a multifaceted strategy that addresses the severity of disease presentation seen in minorities and delivery system capabilities affecting access and use of reconstructive limb salvage procedures. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Medicaid Utilization and Spending among Homeless Adults in New Jersey: Implications for Medicaid-Funded Tenancy Support Services.

Policy Points Large numbers of homeless adults gained Medicaid coverage under the Affordable Care Act, increasing policymaker interest in strategies to improve care and reduce avoidable hospital costs for homeless populations. Compared with nonhomeless adult Medicaid beneficiaries, homeless adult beneficiaries have higher levels of health care needs, due in part to mental health issues and substance use disorders. Homeless adults are also more likely to visit the emergency department or require inpatient admissions. Emergency care and inpatient admissions may sometimes be avoided when individuals have high-quality community-based care and healthful living conditions. Offering tenancy support services that help homeless adults achieve stable housing may therefore be a cost-effective strategy for improving the health of this vulnerable population while reducing spending on avoidable health care interventions. Medicaid beneficiaries with disabling health conditions and more extensive histories of homelessness experience the most potentially avoidable health care interventions and spending, with the greatest opportunity to offset the cost of offering tenancy support benefits. CONTEXT: Following Medicaid expansion under the Affordable Care Act, the number of homeless adults enrolled in Medicaid has increased. This has spurred interest in developing Medicaid-funded tenancy support services (TSS) for homeless populations as a way to reduce Medicaid spending on health care for these individuals. An emerging body of evidence suggests that such TSS can reduce avoidable health care spending. METHODS: Drawing on linked Homeless Management Information System and Medicaid claims and encounter data, this study describes the characteristics of homeless adults who could be eligible for Medicaid TSS in New Jersey and compares their Medicaid utilization and spending patterns to matched nonhomeless beneficiaries. FINDINGS: More than 8,400 adults in New Jersey were estimated to be eligible for Medicaid TSS benefits in 2016, including approximately 4,000 living in permanent supportive housing, 800 formally designated as chronically homeless according to federal guidelines, 1,300 who were likely eligible for the chronically homeless designation, and over 2,000 who were at risk of becoming chronically homeless. Homeless adults in our study were disproportionately between the ages of 30 and 64 years, male, and non-Hispanic blacks. The homeless adults we studied also tended to have very high burdens of mental health and substance use disorders, including opioid-related conditions. Medicaid spending for a homeless beneficiary who was potentially eligible for TSS was 10% ($1,362) to 27% ($5,727) more than spending for a nonhomeless Medicaid beneficiary matched on demographic and clinical characteristics. Hospital inpatient and emergency department utilization accounted for at least three-fourths of "excess" Medicaid spending among the homeless groups. CONCLUSIONS: A large group of high-need Medicaid beneficiaries could benefit from TSS, and Medicaid funding for TSS could reduce avoidable Medicaid utilization and spending.

The Policy and Practice Legacy of the New Jersey Medicaid ACO Demonstration Project.

The New Jersey Medicaid Accountable Care Organization (ACO) Demonstration was created with a unique combination of features regarding ACO geography, involvement of managed care organizations (MCOs), and shared savings parameters. Ultimately, the Demonstration did not lead to a sustainable accountable care financing model and shared savings were deemphasized. Instead, the ACOs evolved into community health coalitions focused on coordinating and enhancing a wide range of activities in partnership with state government, private health systems, community leaders, and MCOs. Currently, the state is developing policy parameters to reposition the ACOs as regional partners to implement state-directed population health initiatives.
