Factors Associated with Physical Activity Increases and Decreases Among a Sample of Appalachian Residents During the COVID-19 Pandemic: A Cross-Sectional Study.

Introduction: Physical activity (PA) can prevent and reduce the deleterious physical and mental health effects of COVID-19 and associated lockdowns. Research conducted early in the pandemic demonstrates that a greater proportion of adults in the U.S. have decreased than increased PA, and the effects vary by sociodemographic factors. Ongoing evidence is important to identify patterns in PA changes during the pandemic. Purpose: This study aims to identify factors associated with increases and decreases in PA during the COVID-19 pandemic in a convenience sample of adults residing in Appalachia. Methods: Surveys were collected from a convenience sample of adults from eight counties in West Virginia from January to March 2021. Logistic regression analysis was used to identify sociodemographic, health, and rurality factors associated with (1) increased PA and (2) decreased PA during the pandemic, assessed retrospectively via self-report. Results: Analysis of 1,401 survey responses revealed that better self-rated health, lower body mass index, and higher income and education were associated with a greater likelihood of more time spent doing PA during the pandemic ( p ≤ .05). Respondents with lower self-rated health, higher body mass index, lower income, and lower levels of education-plus females and those living in a more urban county-were more likely to spend less time doing PA during the pandemic ( p ≤ .05). Implications: Analyses suggest that pre-pandemic disparities in PA by health, wealth, and education were exacerbated during the pandemic. These must be addressed before physical inactivity and ill health become endemic to the Appalachian Region.

Lessons learned from employing Medicaid-funded peer recovery support specialists in residential substance use treatment settings: An exploratory analysis.

INTRODUCTION: This article explores the experiences of peer recovery support specialists (PRSS) and their colleagues working in residential adult services (RAS) facilities in a rural state to better understand how the role has been implemented in this setting. In West Virginia, PRSS and RAS services have been covered by Medicaid since 2018 for the treatment of substance use disorder (SUD). Thus, the aim of this study is to uncover what has and has not worked well in the early years of service implementation from the perspectives of both PRSS and their colleagues working in the SUD field. METHODS: The study interviewed forty-eight clinical and administrative staff at RAS facilities, including nine PRSS, across fourteen focus groups between 2020 and 2021. The study asked participants about general knowledge of West Virginia's 1115 Medicaid Waiver supporting the funding of PRSS, communication among providers, transitioning patients to other providers, scope of practice, barriers and facilitators to providing services, ethical challenges, and COVID-19. Data analysis utilized a phenomenological approach to describe individuals' unique experiences. RESULTS: Three core themes emerged from the analysis: (i) Lived Experience as Added Value, (ii) Inadequate Funding for PRSS Position, and (iii) Role Difficulties. Participants described the lived experience of PRSS as both beneficial to the recovery journey of patients with SUD and unique in that only PRSS can provide the specific skillset that benefits these patients; these characteristics also helped facilities to connect patients to supportive resources. Two funding limitations emerged as barriers to PRSS employment: funding available through Medicaid billing was insufficient to hire staff and the corresponding hourly compensation rate was not competitive against those offered via grants. Finally, participants identified an underdeveloped hiring system and an unclear scope of practice that led to staff feeling unsupported. CONCLUSION: PRSS's experiential expertise complements clinical expertise by producing effective health care and support for patients. Despite their high value and expertise in SUD treatment, PRSS face major challenges in the workplace, including inadequate pay, underdeveloped support structures, and narrow job eligibility requirements. Future research should further quantify PRSS's levels of expertise and identify "value-added" benefits of this position.

Drive Times to Methadone Treatment among Medicaid Patients.

OBJECTIVE: To describe round-trip drive times and travel distance to methadone clinics among Medicaid enrollees in West Virginia, testing for differences between those in rural versus urban areas. FINDINGS: In this cross-sectional analysis of West Virginia Medicaid enrollees' claims from 2018-2019, methadone recipients on average traveled almost an hour round-trip to receive their daily treatment. The travel burden was substantially higher among those in more rural areas. Meaning. These findings indicate that it may be difficult for patients to adhere to their methadone treatment regimen, perhaps leading to suboptimal treatment rates and outcomes.

Using adverse childhood experiences to explore the usefulness of community health needs assessments to monitor complex determinants of health at the local level.

BACKGROUND: Hospital led community health needs assessments (CHNAs) are intended to help medical care organizations assess determinants of health within the communities they serve. This study demonstrates the utility of data from non-profit hospital CHNAs to monitor complex health issues such as adverse childhood events (ACEs) at the local-level. METHODS: CHNA data were collected from August to November 2019 and analyzed July 2021. A series of logistic regressions were used to analyze associations between ACEs, mental health conditions, and self-rated health from a convenience sample of 2831 adults from two regional hospitals that service five counties located in central Appalachia. RESULTS: ACEs were associated with increased odds of experiencing all metal health conditions after adjusting for other exposures and demographics, including: bipolar disorder (AOR: 2.42, CL: 1.78, 3.30), chronic pain (AOR: 1.61, CL: 1.438, 1.87), depression (AOR: 2.05, CL: 1.76, 2.36), PTSD (AOR: 3.83, CL: 2.95, 4.98), and poor self-rated health (AOR: 1.88, CL: 1.65, 2.15). CONCLUSION: Findings suggest hospital CHNAs are a useful way to assess local data and should include factors known to antecede disease including associated risks and outcomes. CHNAs may provide an opportunity to fill important gaps in community surveillance and inform local prevention and treatment strategies.

Field Test of a Passive Infrared Camera for Measuring Trail-Based Physical Activity.

Introduction: Trails are ubiquitous and far-reaching, but research on the impact trails have on physical activity is limited by the lack of resource-efficient, accurate, and practical systematic observation tools. Commonly used infrared trail sensors count trail use and may broadly differentiate activity (i.e., bicyclist vs. pedestrian), but cannot detect nuances needed for outcomes research such as frequency, intensity, time, and type of activity. Motion-activated passive infrared cameras (PICs), used in ecological research and visitor management in wildlife areas, have potential applicability as a systematic observation data collection tool. Materials and Methods: We conducted a 7-month field test of a PIC as a systematic observation data collection tool on a hiking trail, using photos to identify each trail user's physical activity type, age, sex, and other characteristics. We also tallied hourly trail use counts from the photos, using Bland-Altman plots, paired t-tests, Concordance Correlation Coefficient, Kendall's Tau-b, and a novel inter-counter reliability measure to test concordance against concurrent hourly counts from an infrared sensor. Results: The field test proved informative, providing photos of 2,447 human users of the trail over 4,974 h of data collection. Nearly all of the users were walkers (94.0%) and most were male (69.2%). More of the males used the trail alone (44.8%) than did females (29.8%). Concordance was strong between instruments (p < 0.01), though biased (p < 0.01). Inter-counter reliability was 91.1% during the field study, but only 36.2% when excluding the hours with no detectable trail use on either device. Bland-Altman plots highlighted the tendency for the infrared sensor to provide higher counts, especially for the subsample of hours that had counts >0 on either device (14.0%; 694 h). Discussion: The study's findings highlight the benefits of using PICs to track trail user characteristics despite the needs to further refine best practices for image coding, camera location, and settings. More widespread field use is limited by the extensive amount of time required to code photos and the need to validate the PICs as a trail use counter. The future potential of PICs as a trail-specific PA research and management tool is discussed.

Systematic Observation of Physical Distancing Behaviors of Trail Users During the COVID-19 Pandemic.

During the early months of the COVID-19 pandemic, opportunities for indoor and sometimes outdoor recreation were restricted across the world. Despite restrictions, many greenways and rail-trails saw increased use. Messaging from the federal and state public health authorities stressed the importance of social distancing and other preventive measures in reducing spread of the coronavirus. Little is known about actual behaviors of individuals and groups using these outdoor recreational opportunities. This study used passive infrared cameras to systematically observe physical distancing behaviors on multi-user trails in Boone, North Carolina, and Morgantown, West Virginia, to assess safety implications of trail use during June 2020. Most interactions (72.2%) occurred with the recommended six feet of distance between users. Maintaining six feet of distance is more likely to occur when a single individual passes another single individual (88.2%), users pass while traveling in opposite directions (75.9%), and trails are wider (76.8% on 12 ft width trail vs. 62.6% on a 10 ft width trail). Messaging on multi-user trails should target how groups pass other groups, such as "keep six feet" and "pass single file."

Assessment and Response to Intimate Partner Violence in Home Visitation: A Qualitative Needs Assessment With Home Visitors in a Statewide Program.

There is growing recognition that home visitation programs serving at-risk families may be an appropriate mechanism for detecting and reducing intimate partner violence (IPV). More research is needed about how home visitors assess and respond to IPV, especially in rural and underserved areas with unique social and geographic challenges. This study describes the qualitative, needs assessment phase of a larger mixed-methods evaluation of IPV assessment, referral processes, and safety planning with clients within a statewide home visitation program. Three focus groups were conducted with home visitors (n = 16) in West Virginia's Home Visitation Program in May 2015. Home visitors represented four separate home visitation models and provided services across 12 of West Virginia's 55 counties. Guiding questions focused on home visitors' current protocol, experiences, barriers, and facilitators to (a) screening and assessment for IPV, (b) making referrals after disclosures of IPV, and (c) developing safety plans with IPV-exposed clients. Barriers identified by home visitors included the nature of assessment tools, issues with service availability and access in rural areas, and lack of education and training surrounding safety planning. Facilitators included building relationships and trust with clients, providing anticipatory guidance when making referrals, and tailoring safety plans to clients' unique situations. Participants also expressed a critical need to develop procedures for assuring home visitor safety when supporting IPV-exposed clients. These qualitative data highlight issues surrounding the management of IPV in home visitation and have the potential to inform future enhancements to programs that are specifically tailored to the needs of rural, disadvantaged communities.

School Climate as a Universal Intervention to Prevent Substance Use Initiation in Early Adolescence: A Longitudinal Study.

Initiation of substance use often starts during adolescence, with tobacco and alcohol use frequently preceding the use of marijuana and other illicit drugs. Studies suggest that a positive school climate may prevent substance use while promoting healthy student behaviors. The purpose of this study was to determine the longitudinal associations between school climate and substance use initiation in a group of middle school students. Parallel latent growth curve modeling was used to examine changes among study variables longitudinally using a sample of 2,097 sixth-, seventh-, and eighth-grade students across 16 regional schools located in three counties in West Virginia. Results suggest that a positive school climate may prevent substance use initiation (ß = -0.07 to -0.25, p < .01). However, perceptions of school climate decreased on their own over time (ß = -0.28 to -0.66, p < .01). Furthermore, substance use initiation also increased as students grew older (ß = 0.96 to 0.99, p < .01) and reduced the effects of school climate longitudinally (ß = -0.07 to -0.24, p < .01). Early substance use initiation may be a warning sign of other underlying student issues and requires additional school support to foster student success. Findings suggest that a positive school climate may delay substance use initiation and promote school success. School climate may, therefore, be useful as an intervention to support school-based health promotion.

The Importance of Individual-Site and System-Wide Community Health Needs Assessments.

In order to fulfill the Patient Protection and Affordable Care Act's Community Health Needs Assessment requirements, hospital systems sometimes vary in detail between individual hospital sites or locations and performing an assessment for the entire system. This article examines needs assessments and their accompanying implementation plans across a large university hospital system and finds support for conducting assessments at the local site-level but evidence that system-wide approaches may also have significant benefits, especially at the implementation phase. It suggests a hybrid approach to the needs assessment process where systems and their individual hospitals work together to maximize health benefits to the communities served.

Adoption and Reach of a statewide policy, systems, and environment intervention to increase access to fresh fruits and vegetables in West Virginia.

Food deserts-areas with limited access to affordable, healthy foods-are disproportionately in low-income areas of the USA and have been linked with poorer nutrition behaviors and health outcomes. From a social ecological perspective, increasing access to affordable fresh fruits and vegetables in communities should encourage consumption and health improvements. Change the Future West Virginia, a statewide intervention, was undertaken to make policy, system, and environment (PSE) changes to enhance access to fresh fruits and vegetables in schools, farmers markets, and retail food outlets. Previous local scale PSE change interventions have shown feasibility and population reach, but broader dissemination has not been evaluated. Thus, the purpose was to evaluate the Adoption and Reach of Change the Future West Virginia statewide nutrition-based PSE strategies, especially in food deserts. Evaluation data were collected monthly using an online performance monitoring tool, including open-ended items to assess barriers and facilitators of PSE changes. Schools from 48 of 55 counties with 261,829 enrollment (54% low-income) implemented 231 PSE activities, resulting in 35 counties serving locally produced foods. Adoption included two thirds (n = 82) of all farmers markets in the state-signed collaboration agreements, adding electronic benefit transfer machines at 29. Retail food Adoption included signed agreements with 22.1% (n = 101) of all grocery stores and 14.1% (n = 162) of all convenience stores in the state reaching 110,258 people (21.5%) in 27 food desert census tracts. Personnel consistency, local connections, and in-person meetings were important for PSE changes, highlighting the importance of human resources in the rural public health system and the potential of these intervention activities in rural, low-income states.

Evaluability assessment of "growing healthy communities," a mini-grant program to improve access to healthy foods and places for physical activity.

BACKGROUND: Mini-grants have been used to stimulate multisector collaboration in support of public health initiatives by funding non-traditional partners, such as economic development organizations. Such mini-grants have the potential to increase access to healthy foods and places for physical activity through built environment change, especially in small and rural towns in the United States. Although a promising practice, few mini-grant evaluations have been done. Therefore, our purpose was to conduct an Evaluability Assessment (EA), which is a process that can help promising programs that lack evidence advance toward full-scale evaluation. Specifically, we conducted an Evaluability Assessment of a statewide mini-grant program, called "Growing Healthy Communities" (GHC), to determine if this program was ready for evaluation and identify any changes needed for future implementation and evaluation that could also inform similar programs. METHODS: Telephone interviews with directors of six past mini-grant recipient organizations were conducted to assess implementation and evaluability. The six interviews were split equally among agencies receiving funding for food-oriented projects and physical activity-oriented projects. Within- and cross-case thematic analyses of interview transcripts were conducted. RESULTS: Organizational capacity was a universal theme, reflecting other key themes (described in detail in the manuscript) that affected program implementation and evaluation, including collaboration, limited time and measurement integration. CONCLUSIONS: The EA process provided pilot data that suggest that other state, regional, and national funders should provide centralized assistance for data collection and evaluation from the outset of a mini-grant award program.

Polypharmacy and Multimorbidity Among Medicaid Enrollees: A Multistate Analysis.

The purpose of this study is to explore the associations between polypharmacy and multimorbidity using conventional and novel measures of polypharmacy. In this cross-sectional study, data on fee-for-service (FFS) Medicaid enrollees with at least 1 chronic condition and aged 18-64 years (N = 38,329) were derived from the 2010 Medicaid Analytic eXtract (MAX) files of Maryland and West Virginia. Polypharmacy, by the authors' novel definition, was determined as simultaneous use of ≥5 drugs for a consecutive period of 60 days. Multimorbidity was defined as having ≥2 chronic conditions based on the US Department of Health and Human Services framework. The association between multimorbidity and polypharmacy was examined with chi-square tests and logistic regression. Polypharmacy prevalence was estimated at 50.9% using the novel definition, as compared to 16.7% and 64.9% for the 2 commonly used conventional measures, respectively. For all 3 definitions, individuals with multimorbidity were more likely to have polypharmacy than those without multimorbidity (P < 0.001). The authors also consistently found, using all definitions, that those who were older, female, white, and eligible for Medicaid because of cash assistance were more likely to have polypharmacy (all P < 0.001). Polypharmacy was highly prevalent and significantly associated with multimorbidity among Medicaid FFS enrollees irrespective of the definitions used. The new measure may provide a more comprehensive and accurate estimation of polypharmacy than the conventional measures. These findings suggest the need for a paradigm shift from disease-specific care to patient-centered collaborative care to manage patients with multimorbidity and polypharmacy.

Evaluation of an Intimate Partner Violence Training for Home Visitors Using the Theory of Planned Behavior.

INTRODUCTION: Intimate partner violence (IPV) is a public health issue with recent intervention focus by home visiting programs with at-risk families in the United States. Home visitors are typically required to assess IPV but feel unprepared to do so and desire training. Our aim was to evaluate the impact of a daylong IPV training on the intention to enact three key IPV behaviors (screening, making referrals, and safety planning) using the theory of planned behavior. METHOD: Survey of 125 home visitors in West Virginia was conducted before and after a daylong IPV training. RESULTS: The IPV training had a positive impact on intention to perform the three behaviors of interest, with the greatest impact on the intention to conduct IPV screenings. DISCUSSION: Results provide important preliminary evidence supporting the effectiveness of professional development as a means of increasing intentions to conduct activities related to IPV. The impact on IPV screening intention is promising because screening is the first step in addressing IPV. CONCLUSION: The IPV training proved beneficial in increasing intentions and such trainings should be expanded, but further study is needed to link intentions to subsequent behaviors to address IPV with at-risk families.

Healthcare resource availability and cardiovascular health in the USA.

OBJECTIVES: Cardiovascular disease (CVD) remains the leading cause of death in the USA. Reducing the population-level burden of CVD disease will require a better understanding and support of cardiovascular health (CVH) in individuals and entire communities. The objectives for this study were to examine associations between community-level healthcare resources (HCrRes) and CVH in individuals and entire communities. SETTING: This study consisted of a retrospective, cross-sectional study design, using multivariable epidemiological analyses. PARTICIPANTS: All participants in the 2011 Behavioral Risk Factor Surveillance System (BRFSS) survey were examined for eligibility. CVH, defined using the American Heart Association CVH Index (CVHI), was determined using self-reported responses to 2011 BRFSS questions. Data for determining HCrRes were obtained from the Area Health Resource File. Regression analysis was performed to examine associations between healthcare resources and CVHI in communities (linear regression) and individuals (Poisson regression). RESULTS: Mean CVHI was 3.3±0.005 and was poorer in the Southeast and Appalachian regions of the USA. Supply of primary care physicians and physician assistants were positively associated with individual and community-level CVHI, while CVD specialist supply was negatively associated with CVHI. Individuals benefiting most from increased supply of primary care providers were: middle aged; female; had non-Hispanic other race/ethnicity; those with household income <$25 000/year; and those in non-urban communities with insurance coverage. CONCLUSIONS: Our results support the importance of primary care provider supply for both individual and community CVHI, though not all sociodemographic groups benefited equally from additional primary care providers. Further research should investigate policies and factors that can effectively increase primary care provider supply and influence where they practice.

Prevalence and Geographic Variations of Polypharmacy Among West Virginia Medicaid Beneficiaries.

BACKGROUND: West Virginia (WV) residents are at high risk for polypharmacy given its considerable chronic disease burdens. OBJECTIVE: To evaluate the prevalence, correlates, outcomes, and geographic variations of polypharmacy among WV Medicaid beneficiaries. METHODS: In this cross-sectional study, we analyzed 2009-2010 WV Medicaid fee-for-service (FFS) claims data for adults aged 18-64 (N=37,570). We defined polypharmacy as simultaneous use of drugs from five or more different drug classes on a daily basis for at least 60 consecutive days in one year. Multilevel logistic regression was used to explore the individual- and county-level factors associated with polypharmacy. Its relationship with healthcare utilization was assessed using negative binomial regression and logistic regression. The univariate local indicators of spatial association method was applied to explore spatial patterns of polypharmacy in WV. RESULTS: The prevalence of polypharmacy among WV Medicaid beneficiaries was 44.6%. High-high clusters of polypharmacy were identified in southern WV, indicating counties with above-average prevalence surrounded by counties with above-average prevalence. Polypharmacy was associated with being older, female, eligible for Medicaid due to cash assistance or medical eligibility, having any chronic conditions or more chronic conditions, and living in a county with lower levels of education. Polypharmacy was associated with more hospitalizations, emergency department visits, and outpatient visits, as well as higher non-drug medical expenditures. CONCLUSIONS: Polypharmacy was prevalent among WV Medicaid beneficiaries and was associated with substantial healthcare utilization and expenditures. The clustering of high prevalence of polypharmacy in southern WV may suggest targeted strategies to reduce polypharmacy burden in these areas.

The Impact of Community Input in Community Health Needs Assessments.

OBJECTIVE: To determine the impact of community participation on nonprofit hospital priorities as outlined in a Community Health Needs Assessment. DESIGN: Using 3 completed Community Health Needs Assessments, we compare key stakeholder survey responses with community survey responses and determine their contribution to the finalized priorities. SETTING: Three communities in West Virginia served by nonprofit hospitals (1 metropolitan statistical area, 1 micropolitan statistical area, and 1 rural community). PARTICIPANTS: Key stakeholders and the general population of communities served by the hospital. MAIN OUTCOME MEASURE: Finalized priorities as outlined in the Community Health Needs Assessment. RESULTS: Community participation had an impact on finalized priorities. CONCLUSION: Community participation is key in identifying unique health needs and should be incorporated into the assessment process by nonprofit hospitals, local health departments, and other public health practitioners. As reforms are considered to the Patient Protection and Affordable Care Act, it will be important to emphasize the importance of community input in identifying ways nonprofit hospitals contribute community benefit. CHNAs without adequate public input may not translate into implementation plans that accurately address pressing health concerns.

Depression Treatment Among Elderly Medicare Beneficiaries With Incident Cases of Cancer and Newly Diagnosed Depression.

OBJECTIVE: Depression treatment can improve the health outcomes of elderly cancer survivors. There is a paucity of studies on the extent to which depression is treated among elderly cancer survivors. Therefore, this study estimated the rates of depression treatment among elderly cancer survivors and identified the factors affecting depression treatment. METHODS: A retrospective cohort study design was adopted, and data were obtained from the linked Surveillance, Epidemiology and End Results (SEER) and Medicare database. Elderly individuals (≥ 66 years) with incident cases of breast, colorectal, or prostate cancer and newly diagnosed depression (N=1,673) were followed for six months after the depression diagnosis to identify depression treatment (antidepressants only, psychotherapy only, combined treatment with both antidepressants and psychotherapy, and no depression treatment). Chi-square tests and multinomial logistic regressions were used to analyze the factors associated with depression treatment. RESULTS: In this study population, 46% received antidepressants only, 27% received no treatment, 18% received combined therapy, and 9% received psychotherapy only. Factors associated with depression treatment included anxiety, the percentage of psychologists at the county level, the number of visits to primary care physicians, ongoing cancer treatment, the presence of other chronic conditions, and race-ethnicity. CONCLUSIONS: The study findings indicate that two-thirds of cancer survivors received depression treatment in the first six months after depression diagnosis. Our study findings indicate that racial-ethnic disparities in depression treatment persist and competing demands for cancer treatment may take priority over depression care. Also, the availability of psychologists may influence receipt of psychotherapy among cancer survivors.

Cancer Type and Risk of Newly Diagnosed Depression Among Elderly Medicare Beneficiaries With Incident Breast, Colorectal, and Prostate Cancers.

BACKGROUND: Elderly individuals (age >65 years) with cancer are at high risk for newly diagnosed depression after a cancer diagnosis. It is not known whether the risk of newly diagnosed depression varies by cancer type. PURPOSE: To examine the variations in the risk of newly diagnosed depression by cancer type among elderly individuals with cancer. METHODS: This study used a retrospective cohort study design and data from the linked SEER-Medicare files. Elderly individuals (age >65 years) with incident breast, colorectal (CRC), and prostate cancers diagnosed between 2007 and 2011 (N=53,821) were followed for 12 months after cancer diagnosis. Depression diagnosis was identified during the 12-month follow-up period after cancer diagnosis using the ICD-9-Clinical Modification. Complementary log-log regression was used to examine the association between cancer type and risk of newly diagnosed depression after adjusting for other risk factors for depression. RESULTS: We found a significantly higher percentage of newly diagnosed depression among women with CRC compared with those with breast cancer (5.8% vs 3.9%), and among men with CRC compared with those with prostate cancer (3.4% vs 1.6%). In the adjusted analysis, women with CRC had a 28.0% higher risk of newly diagnosed depression compared with women with breast cancer (adjusted risk ratio [ARR], 1.28; 95% CI, 1.12-1.46) and men with CRC had a 104.0% higher risk of newly diagnosed depression compared with those with prostate cancer (ARR, 2.04; 95% CI, 1.65-2.51). CONCLUSIONS: Our findings identified cancer types associated with a high risk of newly diagnosed depression after cancer diagnosis, who might benefit from routine depression screening to help in its early detection and treatment.

Longitudinal Patterns of Emergency Department Visits: A Multistate Analysis of Medicaid Beneficiaries.

OBJECTIVE: The objective of this study was to examine the longitudinal patterns of emergency department (ED) visits among adult fee-for-service Medicaid. DATA SOURCES: Data were obtained from the Medicaid analytic eXtract files, Area Health Resource File, and County Health Rankings. STUDY DESIGN: A retrospective longitudinal study design, with four observations for each individual was used. The study population consisted of 33,393 Medicaid beneficiaries who met inclusion criteria. ED visits were time-lagged and time-varying patient-level factors were measured for each year. Time-invariant characteristics (gender and race/ethnicity) were measured in 2006. Multivariable hurdle models with logistic (ED use versus no ED use) and negative binomial regressions (ED visits among ED users) were used to analyze the ED visits over time. To account for correlation due to repeated observations, mixed effect models with robust standard errors were performed. PRINCIPAL FINDINGS: In both unadjusted and adjusted analysis, the likelihood of ED use did not change from year to year (AOR = 1.00, 95 percent CI: 0.99, 1.01). Among ED users, the estimated number of ED visits increased over time (IRR = 1.01, 95 percent CI: 1.01, 1.03). CONCLUSIONS: Primary care resources should be a major focus to reduce the increased burden on the EDs.

Measuring policy and related effects of a health impact assessment related to connectivity.

Health Impact Assessments are an important tool to help policymakers perceive the potential positive and negative contributions of decisions to public health. While they have been increasingly used in the United States, studies have not examined intermediate effects. Using key stakeholder interviews, this manuscript examines policy outcomes and other related effects of the HIA 21months after completing a Health Impact Assessment Report around connectivity policy. Further, it reflects on the measurement of these effects as part of the monitoring and evaluation stage of the Health Impact Assessment process.
