SPOKANE, Wash. — A study completed by the Center for International Health Services Research and Policy based at Washington State University Spokane stresses the importance in the U.S. health system of screening for diabetes type 2 management and prevention.

The study assessed the association between four preventive diabetes screenings (retinal eye exams, HbA1c testing, lipid testing and albumin testing) within the study period, and health services utilization patterns for a two-year follow-up period. The study is based on claims data for 2,641 patients with type 2 diabetes from Regence Blue Shield of Idaho for the three most recent periods of 2000 (base period), 2001 and 2002 (results period).  

Patients who received lipids testing showed a significant overall decrease in inpatient service utilization during the results study period.  Further, recommended screenings of retinal eye exams and albumin testing were associated with an increase in outpatient utilization in the subsequent two years. Lower inpatient utilization and/or higher outpatient services are considered a positive outcome.


The study states: “From a governmental policy perspective, these empirical results point to critical considerations facing federal policy makers. Pursuing a state or federally supported screening program for patients with type 2 diabetes could reduce frequent utilization of inpatient services.”

The paper, entitled “Examining the Association Between Preventive Screenings and Subsequent Health Services Utilization by Patients with Type 2 Diabetes Mellitus,” was authored by assistant professor of health policy and administration Fevzi Akinci; center director and health policy professor Joseph Coyne; Joni Minear, a graduate of the master’s program in health policy; WSU Spokane assistant professor and center post-doctoral fellow Kenn Daratha, and current health policy graduate student Dan Simonson. It was published in the April 2005 issue of Disease Management and Health Outcomes, an international journal published from Auckland, New Zealand.
