Objective: In 2003, Oregon's Medicaid expansion program, the Oregon Health Plan (OHP), implemented premiums and copayments and eliminated outpatient behavioral health services. We ascertained whether these changes, including $50 copayments for emergency department (ED) visits, affected ED use. Methods: This study used statewide administrative data on 414,009 adult OHP enrollees to compare ED utilization rates (adjusted for patient characteristics) in 3 time periods: (1) before the cutbacks, (2) after the cutbacks, and (3) after partial restoration of benefits.

About 7.4 million children were covered by the State Children’s Health Insurance Program (SCHIP) at some point during fiscal year 2008. Many of these children would probably have had private coverage in the absence of SCHIP; recent estimates of the extent of “crowd-out” associated with SCHIP are about 60 percent (Gruber and Simon 2008). The high rate of crowd-out means that the program is not as effective as it could be at reducing the number of uninsured children and has been a political liability for the program.

The Medicare Prescription Drug, Improvement, and Modernization Act, enacted in 2003, substantially reduced payment rates for chemotherapy drugs administered on an outpatient basis starting in January 2005. We assessed how these reductions affected the likelihood and setting of chemotherapy treatment for Medicare beneficiaries with newly diagnosed lung cancer, as well as the types of agents they received. Contrary to concerns about access, we found that the changes actually increased the likelihood that lung cancer patients received chemotherapy.

This report is the fourth and final report in a series that explores the cross-payer effects of providing Medicaid long-term supports and services (LTSS) on Medicare acute care resource use. The report provides a summary of the initial work of a study, described more fully in the first three reports, with an emphasis on lessons that state Medicaid administrators should consider as they move toward more formal programs of integrated care for persons dually eligible for Medicare and Medicaid (or duals, for short).

Medical liability coverage has become increasingly expensive and scarce since 2001, especially for obstetrics and other high-risk specialties. Physicians, whose own fees are constrained, see this as a crisis needing tort reform to cap payouts. Plaintiffs' lawyers fight caps; they blame insurance trends and call for stronger regulation of insurers and physicians.

Background: Some health plans profile physicians on the basis of their relative costs and use these profiles to assign physicians to cost categories. Physician organizations have questioned whether the rules used to attribute costs to a physician affect the cost category to which that physician is assigned. Objective: To evaluate the effect of 12 different attribution rules on physician cost profiles.
