The State of Washington received a State Innovation Models (SIM) $65 million award from the federal Centers for Medicare & Medicaid Services to improve population health and quality of care and reduce the growth of health care costs in the entire state, which has over 7 million residents. SIM is a “complex intervention” that implements several interacting components in a complex, decentralized health system to achieve goals, which poses challenges for evaluation. Our purpose is to present the state-level evaluation methods for Washington's SIM, a 3-year intervention (2016-2018). We apply the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) evaluation framework to structure our evaluation. We create a conceptual model and a plan to use multiple and mixed methods to study SIM performance in the RE-AIM components from a statewide, population-based perspective.

Following an arduous, 6-year policy-making process, Vermont is the first state implementing a unified, statewide all-payer integrated delivery system with value-based payment, along with aligned medical and social service reforms, for almost all residents and providers in a state. Commercial, Medicare, and Medicaid value-based payment for most Vermonters will be administered through a new statewide accountable care organization in 2018–2022. The purpose of this article is to describe the 10 conditions that increased Vermont's readiness to implement statewide system transformation. The authors reviewed documents, conducted internet searches of public information, interviewed key informants annually in 2014–2016, cross-validated factual and narrative interpretation, and performed content analyses to derive conditions that increased readiness and their implications for policy and practice. Four social conditions (leadership champions; a common vision; collaborative culture; social capital and collective efficacy) and 6 support conditions (money; statewide data; legal infrastructure; federal policy promoting payment reform; delivery system transformation aligned with payment reform; personnel skilled in system reform) increased Vermont's readiness for system transformation. Vermont's experience indicates that increasing statewide readiness for reform is slow, incremental, and exhausting to overcome the sheer inertia of large fee-based systems. The new payments may work because statewide, uniform population-based payment will affect the health care of almost all Vermonters, creating statewide, uniform provider incentives to reduce volume and making the current fee-based system less viable. The conditions for readiness and statewide system transformation may be more likely in states with regulated markets, like Vermont, than in states with highly competitive markets.

BACKGROUND: In 2003, Group Health implemented a pharmacy-based, systemwide outreach effort to increase the preventive use of statins and angiotensin-converting enzyme inhibitors in enrollees at risk for cardiovascular disease, including all enrollees with diabetes. OBJECTIVE: To estimate the associations between the use of statins and major vascular events and the total costs in 2006-2010 for enrollees with diabetes, using a pharmacy-based, systemwide outreach. METHODS: In a 14-year (1997-2010) longitudinal cohort study design, the study population consisted of 6,975 Group Health enrollees with type 1 or type 2 diabetes, who were enrolled continuously and had no statin use before the Group Health outreach in 1997-2002. Health outcomes were all cause mortality, cardiovascular mortality, myocardial infarction, and stroke. Statin exposure was measured by cumulative statin use since 2003, weighted by the effect of the statin type and dose on the lowering of low-density lipoprotein levels. Regression models estimated associations between cumulative statin use, health outcomes, and total costs in 2006-2010. RESULTS: Among enrollees with no statin use before outreach began in 2003, about half had no or low exposure to statins by the end of 2005. In 2006-2010, cumulative statin use was greater among enrollees with risk factors for cardiovascular disease. Greater statin use was related to lower cardiovascular deaths and incidence of stroke and myocardial infarction, greater but nonsignificant all-cause mortality, and unrelated to total costs. CONCLUSIONS: Population-based pharmacy outreach increased statin use for eligible enrollees with diabetes, which was related to better cardiovascular outcomes. Generally, statin use was unrelated to all-cause mortality and total costs. Copyright (C) 2016, Academy of Managed Care Pharmacy. All rights reserved.

Our study aim was to determine whether local health department (LHD) services were associated with U.S. racial disparities in 1993-to-2005 mortality rates. In a national sample of LHDs, we examined 10 LHD service domains and gaps in Black–White all-cause mortality rates, drawing data from the National Association of County and City Health Officials’ National Profile of Local Health Departments surveys, as well as mortality and other public data files. Two service domains, maternal/child health and other activities, were significantly associated with decreases in the Black–White mortality gap for 15- to 44-year-olds. The health services domain approached significance in decreasing this gap. Screening was associated unexpectedly with a significant increase in the Black–White mortality gap for 15- to 44-year-olds. Selected LHD services that are provided directly to individuals and are allocated by need may have particular benefit for reducing Black–White mortality disparities for U.S. adults aged 15 to 44.

The authors examined whether Group Health’s Access Initiative changed the utilization and costs of care among enrollees with diabetes. Using a single (one-group) interrupted time series design, repeated-measures generalized estimating equation models were used to estimate changes in utilization and costs during the Initiative rollout (2002-2003) and to compare the slopes (annual rates of change) for utilization and costs during the Pre-Initiative period (1998-2002) to the slopes during Full-Implementation (2003-2006) among 9,871 members continuously enrolled from 1997 to 2006 with type 1 or 2 diabetes. Total costs increased in Full-Implementation, but the annual change in total costs did not change. Primary care visits declined, but primary care contacts grew, largely from the Initiative’s introduction of secure messaging. Specialty visits did not change; however, the Initiative may have increased emergency visits. To reduce emergency visits, future access initiatives should include proactive and comprehensive outpatient care for patients with diabetes.

For low-income mothers of children aged 3-6 years, we estimate whether social gradients exist between mothers' income, education, and employment status and mothers' perceptions of self and child dental and general health, and whether these relationships differ by racial/ethnic group. Disproportionate stratified sampling by racial/ethnic group selected 10,909 eligible children aged 3 to 6 in Medicaid in Washington State. Mothers (n=4,373) completed a mixed-mode (web, mail, telephone) survey. Mothers' education had a strong, gradient relationship with mother ratings of self and child dental health that was not explained by other measures. Similar gradients were found for mothers' employment status and income, but some associations were no longer significant (p>.05) after adjusting for oral health beliefs and behaviors, dental insurance, and regular dental care. Associations did not differ significantly by racial/ethnic group.

Abstract –  Objectives:  The authors examined whether low‐income mothers, who have a regular source of dental care (RSDC), rate the dental health of their young children higher than mothers without an RSDC.Methods:  From a population of 108 151 children enrolled in Medicaid aged 3 to 6 years and their low‐income mothers in Washington state, a disproportionate stratified random sample of 11 305 children aged 3 to 6 years was selected from enrollment records in four racial/ethnic groups: 3791 Black; 2806 Hispanic; 1902 White; and 2806 other racial/ethnic groups. A mixed‐mode survey was conducted to measure mother RSDC and mother ratings of child’s dental health and pain. The unadjusted response rate was 44%, yielding the following eligible mothers: 816 Black, 1309 Hispanic, 1379 White, 237 Asian, and 133 American‐Indian. Separate regression models for Black, Hispanic, and White mothers estimated associations between the mothers having an RSDC and ratings of child dental health.Results:  Across racial/ethnic groups, mothers with an RSDC consistently rated their children’s dental health 0.15 higher on a 1‐to‐5 scale (where ‘1’ means ‘poor’ and ‘5’ means ‘excellent’) than mothers without an RSDC, controlling for child and mother characteristics and the mothers’ propensity to have an RSDC. This difference can be interpreted as a net movement of one level up the scale by 15% of the population.Conclusions:  Across racial/ethnic groups, low‐income mothers who have a regular source of dental care rate the dental health of their young children higher than mothers without an RSDC.
