This dissertation uses the New Hampshire APCD to examine whether commercial insurers increase claim denial rates ahead of the predictable transition to Medicare at age 65, finding statistically significant spikes in denials — particularly for lab tests, durable medical equipment, and musculoskeletal procedures — consistent with cost-shifting behavior the author defines as corporate moral hazard.

This study quantifies a major shift in locus of VA critical care, a likely outcome of expanded non-VA health insurance coverage that was previously called out, but the study was not designed to address the many issues raised by outsourcing so much ICU care, including questions about the coordination and continuity of post-ICU care for these patients with high-acuity conditions. The study adds to concerns about VA’s ability to oversee the quality of community care and gaps in the integration of VA-delivered and VA-purchased care.

Focusing on medical imaging procedures, this paper examines the equilibrium effect of a unique statewide price transparency website. Price information leads to a shift to lower-cost providers, especially for patients subject to a deductible

The project published an Atlas and the project's first journal paper was released online August 2014 in Pediatrics (Weinstein SJ, House SA, Chang CH, Wasserman JR, Goodman DC, Morden NE.

The HealthCost website (http://www.nhhealthcost.org/) provides information for consumers and employers about the price of medical care in New Hampshire by insurance plan and by procedure. It also provides the estimate price of medical care for the uninsured. Price information is based on paid claims data collected from New Hampshire's health insurers by the New Hampshire Department of Health and Human Services as part of the Comprehensive Health Care Information System (NH’s APCD system).
