| Acute stroke care coordination in the United States: Variation in state laws for emergency medical services and hospitals
Ye Z , Gilchrist S , Omeaku N , Shantharam S , Ritchey M , Coleman King SM , Sperling L , Holl JL . J Stroke Cerebrovasc Dis 2024 108174 BACKGROUND: Lack of care coordination between Emergency Medical Services (EMS) and hospitals contributes to delay of acute stroke (AS) treatment. In the United States, states have adopted laws to improve the quality of EMS and hospital care; the degree to which these laws create regulatory incentives to promote care coordination between them is less well known. We examined state variation in attributes of laws that may influence AS care coordination between EMS and hospitals. MATERIALS AND METHODS: We selected ten law "dyads" across seven domains of EMS and hospital AS care informed by published risk assessments of critical steps for improved door-to-needle time and door-in-door-out time. We assessed concordance in prescriptiveness (degree to which levels were similar) and in adoption (degree to which laws were adopted concurrently) of the laws in effect between January 2002 and January 2018 in the United States. RESULTS: The proportion of states with prescriptiveness concordance ranged from 47% (e.g., inter-facility transfer agreements, comprehensive, primary stroke center certification) to 75% (e.g., Continuous Quality Improvement (CQI) for EMS and hospitals). Adoption concordance ranged from 31% (e.g., inter-facility transfer agreements, Acute Stroke Ready Hospital certification) to 86% (e.g., CQI for EMS and hospitals). Laws for EMS triage were less prescriptive than laws for stroke center certification in 22%-35% of states adopting both laws, depending on stroke center type. CONCLUSIONS: Subsequent policy implementation and impact studies may benefit from assessing concordance and prescriptiveness in policy intervention adoption, particularly as a foundation for evaluating delays in AS treatment due to inefficient care coordination. |
| Racial and ethnic differences in hypertension-related telehealth and in-person outpatient visits before and during the COVID-19 pandemic among Medicaid Beneficiaries
Lee JS , Bhatt A , Pollack LM , Jackson SL , Omeaku N , Lowe Beasley K , Wilson C , Luo F , Roy K . Telemed J E Health 2024 Background: Little is known about the trends and costs of hypertension management through telehealth among individuals enrolled in Medicaid. Methods: Using MarketScan(®) Medicaid database, we examined outpatient visits among people with hypertension aged 18-64 years. We presented the numbers of hypertension-related telehealth and in-person outpatient visits per 100 individuals and the proportion of hypertension-related telehealth outpatient visits to total outpatient visits by month, overall, and by race and ethnicity. For the cost analysis, we presented total and patient out-of-pocket (OOP) costs per visit for telehealth and in-person visits in 2021. Results: Of the 229,562 individuals, 114,445 (49.9%) were non-Hispanic White, 80,692 (35.2%) were non-Hispanic Black, 3,924 (1.71%) were Hispanic. From February to April 2020, the number of hypertension-related telehealth outpatient visits per 100 persons increased from 0.01 to 6.13, the number of hypertension-related in-person visits decreased from 61.88 to 52.63, and the proportion of hypertension-related telehealth outpatient visits increased from 0.01% to 10.44%. During that same time, the proportion increased from 0.02% to 13.9% for non-Hispanic White adults, from 0.00% to 7.58% for non-Hispanic Black adults, and from 0.12% to 19.82% for Hispanic adults. The average total and patient OOP costs per visit in 2021 were $83.82 (95% confidence interval [CI], 82.66-85.05) and $0.55 (95% CI, 0.42-0.68) for telehealth and $264.48 (95% CI, 258.87-269.51) and $0.72 (95% CI, 0.65-0.79) for in-person visits, respectively. Conclusions: Hypertension management via telehealth increased among Medicaid recipients regardless of race and ethnicity, during the COVID-19 pandemic. These findings may inform telehealth policymakers and health care practitioners. |
| Policy implementation strategies to address rural disparities in access to care for stroke patients
Rasool A , Bailey M , Lue B , Omeaku N , Popoola A , Shantharam SS , Brown AA , Fulmer EB . Front Health Serv 2023 3 1280250 CONTEXT: Stroke systems of care (SSOC) promote access to stroke prevention, treatment, and rehabilitation and ensure patients receive evidence-based treatment. Stroke patients living in rural areas have disproportionately less access to emergency medical services (EMS). In the United States, rural counties have a 30% higher stroke mortality rate compared to urban counties. Many states have SSOC laws supported by evidence; however, there are knowledge gaps in how states implement these state laws to strengthen SSOC. OBJECTIVE: This study identifies strategies and potential challenges to implementing state policy interventions that require or encourage evidence-supported pre-hospital interventions for stroke pre-notification, triage and transport, and inter-facility transfer of patients to the most appropriate stroke facility. DESIGN: Researchers interviewed representatives engaged in implementing SSOC across six states. Informants (n = 34) included state public health agency staff and other public health and clinical practitioners. OUTCOMES: This study examined implementation of pre-hospital SSOCs policies in terms of (1) development roles, processes, facilitators, and barriers; (2) implementation partners, challenges, and solutions; (3) EMS system structure, protocols, communication, and supervision; and (4) program improvement, outcomes, and sustainability. RESULTS: Challenges included unequal resource allocation and EMS and hospital services coverage, particularly in rural settings, lack of stroke registry usage, insufficient technologies, inconsistent use of standardized tools and protocols, collaboration gaps across SSOC, and lack of EMS stroke training. Strategies included addressing scarce resources, services, and facilities; disseminating, training on, and implementing standardized statewide SSOC protocols and tools; and utilizing SSOC quality and performance improvement systems and approaches. CONCLUSIONS: This paper identifies several strategies that can be incorporated to enhance the implementation of evidence-based stroke policies to improve access to timely stroke care for all patient populations, particularly those experiencing disparities in rural communities. |
| Impact of state stroke systems of care laws on stroke outcomes
Fulmer EB , Keener Mast D , Godoy Garraza L , Gilchrist S , Rasool A , Xu Y , Brown A , Omeaku N , Ye Z , Donald B , Shantharam S , Coleman King S , Popoola A , Cincotta K . Healthcare (Basel) 2023 11 (21) Since 2003, 38 US states and Washington, DC have adopted legislation and/or regulations to strengthen stroke systems of care (SSOCs). This study estimated the impact of SSOC laws on stroke outcomes. We used a coded legal dataset of 50 states and DC SSOC laws (years 2003-2018), national stroke accreditation information (years 1997-2018), data from the Healthcare Cost and Utilization Project (years 2012-2018), and National Vital Statistics System (years 1979-2019). We applied a natural experimental design paired with longitudinal modeling to estimate the impact of having one or more SSOC policies in effect on outcomes. On average, states with one or more SSOC policies in effect achieved better access to primary stroke centers (PSCs) than expected without SSOC policies (ranging from 2.7 to 8.0 percentage points (PP) higher), lower inpatient hospital costs (USD 610-1724 less per hospital stay), lower age-adjusted stroke mortality (1.0-1.6 fewer annual deaths per 100,000), a higher proportion of stroke patients with brain imaging results within 45 min of emergency department arrival (3.6-5.0 PP higher), and, in some states, lower in-hospital stroke mortality (5 fewer deaths per 1000). Findings were mixed for some outcomes and there was limited evidence of model fit for others. No effect was observed in racial and/or rural disparities in stroke mortality. |
| Rural and urban differences in hypertension management through telehealth before and during the COVID-19 pandemic among commercially insured patients
Lee JS , Bhatt A , Jackson SL , Pollack LM , Omeaku N , Lowe K , Wilson C , Luo F , Roy K . Am J Hypertens 2023 BACKGROUND: The COVID-19 pandemic prompted a rapid increase in telehealth use. However, limited evidence exists on how rural and urban residents used telehealth and in-person outpatient services to manage hypertension during the pandemic. METHODS: This longitudinal study analyzed 701,410 US adults (18-64 years) in the MarketScan Commercial Claims Database, who were continuously enrolled from January 2017 through March 2022. We documented monthly numbers of hypertension-related telehealth and in-person outpatient visits (per 100 individuals), and the proportion of telehealth visits among all hypertension-related outpatient visits, from January 2019 through March 2022. We used Welch's 2-tail t-test to differentiate monthly estimates by rural-urban status and month-to-month changes. RESULTS: From February through April 2020, the monthly number of hypertension-related telehealth visits per 100 individuals increased from 0.01 to 6.05 (P<0.001) for urban residents and from 0.01 to 4.56 (P<0.001) for rural residents. Hypertension-related in-person visits decreased from 20.12 to 8.30 (P<0.001) for urban residents and from 20.48 to 10.15 (P<0.001) for rural residents. The proportion of hypertension-related telehealth visits increased from 0.04% to 42.15% (P<0.001) for urban residents and from 0.06% to 30.98% (P<0.001) for rural residents. From March 2020 to March 2022, the monthly average of the proportions of hypertension-related telehealth visits was higher for urban residents than for rural residents (10.19% vs. 6.96%; P<0.001). CONCLUSIONS: Data show that rural residents were less likely to use telehealth for hypertension management. Understanding trends in hypertension-related telehealth utilization can highlight disparities in the sustained use of telehealth to advance accessible health care. |
