SHARE Research at ASHEcon 2016
June 15, 2016:Seven research teams are presenting their SHARE-funded work at the 2016 American Society of Health Economics Conference (ASHEcon), which takes place this year at the Leonard Davis Institute for Health Economics at the University of Pennsylvania from June 12th through the 15th. We encourage you to check out these presentations if you’re attending the conference.
Podium presentations of SHARE-funded research at ASHEcon 2016 are as follows:
Early Evidence on Employment Responses to the Affordable Care Act
Speaker: Jean Abraham (University of Minnesota)
Discussant: Laura Dague (Texas A&M)
Date/Time: Monday (6/13), 10:55 a.m.
Location: G50 (Huntsman Hall)
As the insurance market changes with the implementation of the ACA, this research examines how the existence of employer-based health insurance coverage impacts employees’ access to such insurance as well as labor market outcomes, such as part-time work. Researchers investigate how labor market outcomes are changing over time as the ACA is implemented.
Speaker: Pinar Karaca-Mandic (University of Minnesota)
Discussant: Anthony LoSasso (University of Illinois at Chicago)
Date/Time: Monday (6/13), 5:25 p.m.
Location: B26 (Stiteler Hall)
This research documents the relationship between television media campaigns and health insurance enrollment, as federal and state governments, as well as nonprofit organizations, spent over $3 billion on media advertising to promote newly available insurance through ACA marketplaces in the first open enrollment period.
Choice Dynamics of “Money Wasting” Plan Choices in ACA State Marketplaces
Speaker: Anna Sinaiko (Harvard University)
Discussant: Chapin White (RAND)
Date/Time: Wednesday (6/15), 8:50 a.m.
Location: G60 (Huntsman Hall)
This research examines the decisions made by people, particularly members of vulnerable populations, in choosing health insurance plans that potentially result in wasted money. The researchers surveyed enrollees in the ACA marketplace in 2015 to determine whether enrollees were enrolled in the most cost effective plan.
Speaker: Lindsay M. Sabik (Virginia Commonwealth University)
Discussant: Ari B. Friedman (University of Pennsylvania)
Date/Time: Wednesday (6/15), 9:10 a.m.
Location: G50 (Huntsman Hall)
This study examines the impact of early Medicaid expansion in California on admissions of patients at safety net hospitals, defined as hospitals that serve a disproportionately high number of uninsured and Medicaid patients. By comparing California hospital admissions from 2010-2013 to other states that did not experience significant changes to their Medicaid coverage during this time period, the researchers find that both safety net and non-safety net hospitals in California experienced an increase in Medicaid patient admissions and decreases in uninsured admissions.
Pent-up Health Care Demand Among New Medicaid Enrollees after the Affordable Care Act
Speaker: Angela Fertig (Medica Research Institute)
Discussant: James Marton (Georgia State University)
Date/Time: Wednesday (6/15), 12:40 p.m.
Location: F55 (Huntsman Hall)
This study examines claims data for evidence of pent-up demand for health care, meaning that newly insured individuals access care at higher rates due to delaying or foregoing care while uninsured or underinsured, for new Medicaid enrollees in Minnesota.
Poster presentations of SHARE-funded research at ASHEcon 2016 are as follows:
Specialty Drug Benefit Design and Patient Out-of-Pocket Costs in the ACA Health Insurance Exchanges
Speaker: Erin A.Taylor (RAND)
Date/Time: Tuesday (6/14), 12:00 p.m.
Location: Annenberg Center, Lobby
Insurers often require more cost sharing from patients for high-cost specialty drugs, meaning that patients end up paying more money out-of-pocket for these drugs than they would for other drugs. This research simulates potential out-of-pocket costs in health exchange plans for patients taking three specialty drugs.
Speaker: Michael Dworsky
Date/Time: Tuesday (6/14), 12:00 p.m.
Location: Annenberg Center, Lobby
Overview: This research examines the impact of the ACA’s Medicaid expansion on insurance status and type of coverage for adults who became newly eligible for Medicaid in 2014. The researchers use 2009 – 2014 data from the National Health Interview Survey to estimate the effect of Medicaid expansion on insurance status, and compare states that chose to expand Medicaid coverage to states that chose not to do so. They find that expanding Medicaid to non-disabled childless adults in poverty reduced uninsurance rates without impacting the number of enrollees on private market plans.

New Brief: Using HCUP Data for State Health Policy Analysis
May 12, 2017:The SHARE grant program has released a new brief examining the use of administrative data for the purpose of state health policy analysis. In particular, the brief highlights the hospital administrative data available from the Healthcare Cost and Utilization Project (HCUP) and presents a case study of a SHARE-funded project that uses HCUP data to evaluate the impacts of California’s early ACA Medicaid expansion on inpatient hospital utilization.
What is the HCUP?
The HCUP is a collection of six different databases sponsored by the federal Agency for Healthcare Research and Quality (AHRQ) that can be purchased through the HCUP Central Distributor. These databases consist of longitudinal hospital data—with a primary focus on community hospitals--based on de-identified discharge records for individual patients. The six different HCUP databases are:
- • National Inpatient Sample (NIS)
- • Kids’ Inpatient Database (KID)
- • Nationwide Emergency Department Sample (NEDS)
- • Nationwide Readmissions Database (NRD)
- • State Inpatient Databases (SID)
- • State Emergency Department Databases (SEDD)
Using HCUP Data to Examine State-Level Utilization
For state-focused health policy research, the State Inpatient Databases (SID), which consist of hospital inpatient discharge data on approximately 90 percent of all U.S. hospital discharges, are especially useful for understanding patient utilization. The SID not only allow researchers to examine hospital-level differences within states but also foster multi-state comparisons and analyses because of their uniformity.
Case Study: Early Medicaid Expansion in California
Researchers at Virginia Commonwealth University (VCU), led by Dr. Peter Cunningham, used the SID to examine the utilization impact of California’s early Medicaid expansion. Specifically, the research team compared
- Utilization at hospitals in California from 2010 to 2013 with utilization at hospitals in neighboring states without an early Medicaid expansion, and
- Utilization over the same time period at safety net and non-safety net hospitals within California.
Preliminary Findings: Highlights
Preliminary findings from the VCU study include (among others):
- • Inpatient volumes increased at California hospitals relative to the comparison states following California’s Medicaid expansion, when controlling for national trends.
- • Medicaid admissions as a percent of total admissions increased after California’s Medicaid expansion, while uninsured admissions declined when compared to non-expansion states (again, controlling for national trends).
- • Overall inpatient volumes at safety net hospitals within California increased to a greater extent than at the state’s non-safety net hospitals following the early Medicaid expansion.
- • Both safety net and non-safety net hospitals within California observed similar patterns in payer mix after the Medicaid expansion, with an increase in Medicaid admissions as a percent of total admissions and a decrease in uninsured admissions as a percent of total admissions.

Using HCUP Data for State Health Policy Analysis: A Case Study Examining the Impacts of an Early Medicaid Expansion
This brief from the SHARE grant program examines a rich source of US hospital administrative data--the Healthcare Cost and Utilization Project (HCUP)--and provides an example of how a SHARE-funded research project led by Dr. Peter Cunningham at Virginia Commonwealth University has used these data to evaluate the impacts of an early ACA Medicaid expansion on utilization-related outcomes at hospitals in California.
