Purpose of request

Estimating impact of ARR on HIE enrollees: The Auto-Reenrollment and Renewal (ARR) policy on the Health Insurance Exchanges (HIEs) was designed to prevent unintentional discontinuous enrollment among HIE enrollees by automatically reenrolling enrollees in their default health plan if an active selection was not made during open enrollment. However, in the five years since ARR was implemented, policymakers have become concerned that ARR is enhancing consumer inertia that is then distorting market signals on the HIEs and increasing premiums, and have considered modifying ARR. The purpose of this research is to establish the impact of ARR on consumer inertia and consumer welfare within HIEs.

Purpose of request

This study seeks to identify racial and geographic disparities in the care of Parkinson’s disease (PD) in Washington State, particularly King County. The study will use medical records (Medicare, Medicaid, and commercial) to characterize PD-related diagnoses, treatment, and specialty care in WA zip codes and to then determine how zip code or African American, Asian American, Latino American, and American/Alaskan Indian race/ethnicity may influence PD care. Using findings from these analyses, a pilot program will be designed to target underserved communities and help them better access specialist care and community services. More particularly, the pilot will identify and assess barriers to people with PD accessing specialized care (e.g., transportation, location and hours of medical facilities, marketing) and design access programs and interventions that address those barriers, including mechanisms that incentivize community doctors and primary care physicians to refer PD patients on to Movement Disorder Specialists. The study and pilot will initially address disparities within the African-American population of SE Seattle and South King County in contrast to the African American population of NW and North King County, with the idea that other population groups can be addressed in a future phase 2 project. By completing both the initial study and the pilot program, patients diagnosed with PD may be better served so that they can live healthier and longer lives, while reducing costs to the health-care system as a whole.

Purpose of request

The main purpose of this project is to support the WSMA’s role on the Surprise Billing Workgroup created by 2HSB 1065 with a goal of reducing healthcare costs for Washington’s patients. We will analyze the WA-APCD data to assess variations in costs by procedure and geography to identify differentials in utilization of out-of-network providers. The Surprise Billing Workgroup is responsible for advising how best to use the WA-APCD to establish commercially reasonable reimbursement. Specifically, our aims are to 1) support the determination of a commercially reasonable reimbursement from the WA-APCD data, 2) have data-driven awareness of ways in which WSMA can implement best practices to support legislature’s efforts around this bill. These two aims enable us to drive toward our mission to “Provide strong physician leadership and advocacy to shape the future of medicine and advance quality care for all Washingtonians.” We would like a fully-formed understanding of the bill’s impact on Washington State’s healthcare ecosystem, as our association plays an important role representing the physicians and physician assistants in our state. The results will not be used for commercial purposes.

Purpose of request

Currently due to improved screening, earlier detection, and advanced cancer therapy, two thirds U.S. cancer patients can live longer than five years. There were more than 15.5 million U.S. cancer survivors alive in 2016. However, cancer patients have eight times higher risk of developing cardiovascular disease (CVD) than non-cancer patients, due to the cardio-toxic cancer therapies and shared risk factors. Since multisystem comorbidity requires care from multiple specialties, an effective relationship between oncologists and cardiologists may be essential to achieving optimal care. However, the question of how to build such an effective relationship between oncologists and cardiologists to obtain optimal outcomes remains unanswered. To assist decision making of cancer patients, providers and communities, Zhi Pan’s proposed PhD dissertation aims to provide an understanding of the oncologist-cardiologist relationship and thereby facilitate better design of more effective approaches for pursuing optimal prevention, treatment, and population health of adult cancer patients at high risk of developing CVD. This study has three aims: (1) Identify distinct patterns of the oncologist cardiologist relationship in caring for the target population. (2) Determine the impact of oncologist cardiologist relationship on outcomes and quality of care for the target population. (3) Test whether payer status and coverage, provider features, patient demography, and community characteristics affect the oncologist-cardiologist relationship and patient outcomes for the target population.

Purpose of request

DUA amendment to add a use case and file linkage fee. This study focuses on a cohort of Washington State children between zero to three years’ old who participated in Early Support for Infants & Toddlers (ESIT) program. We will follow their education paths in pre-K and Kindergarten and investigate the role of health factors in children’s education outcomes. Particularly, we profile the population by their eligibility for early learning intervention services due to specific developmental delays or disability. In addition, by connecting with Washington State All Payers Claims Database (APCD), using linkage data elements (i.e., internal_member_id, first name, last name, middle name, gender, date of birth, and ssn) we will investigate what medical diagnosis and procedures these children have received and cluster condition specific sub-populations.

Purpose of request

Each year there are about 4 million births in the US. About 70% of women take at least one prescription medication in pregnancy, and for many of these medications, there is inadequate safety data. Large observational studies are instrumental in closing this evidence gap because pregnant women are routinely excluded from clinical trials. Our team has had many successes in generating evidence on the safety of medications used in pregnancy including antibiotics, antihypertensive medications, and antidepressants. To study an even wider range of medications and evaluate more important but rarer outcomes, we will need to draw on larger data resources, such as WA-APCD, to identify large populations of pregnant women and their infants. The objective of this research proposal is to carry out feasibility work to investigate whether the Washington State All-Payer Database can be used to study medication use in pregnancy. Specifically, we will investigate means to identify pregnancies and to link mothers’ data to their babies. Once we can establish this data linkage, we will conduct descriptive analyses to support grant applications. For instance, we’ll count the number of mom-baby pairs contained in WA-APCD and describe their characteristics, examine frequency of use of various medication classes in pregnancy, and describe the prevalence of outcomes of interest such as birth defects. We may submit a conference abstract and a manuscript describing methods we used to link moms and babies with aggregated data as described above. Ultimately, results from future research based on the WA-APCD data could help pregnant women and their clinicians make informed decisions about medication treatment in pregnancy.

The data will be used for multiple purposes, including the following: (1) Enable hospitals to improve patient safety by focusing on best practices. The data will be used to support the direct work WSHA is doing on patient safety improvements. For example, data will be used to identify the patterns of severe maternal morbidity and identify interventions to reduce the incidence of severe maternal morbidity and mortality. The data will be used to identify the type of transition care that can help reduce preventable readmissions and improve outcomes. (2) Assist critical access hospitals and the residents in their communities to make informed choices about restructuring the local health care delivery system. The data will be used to identify how critical access hospitals can better meet the needs of the community with a concentration on providing value-based care for essential services. (3) Analyze disease incidents and determine ways to improve the value of the healthcare system.
