Professor Grembowski's evaluation interests address prevention and the performance of health care systems, as well as the social determinants of population health and health inequalities. His studies have examined health care for adults with chronic conditions, efforts to improve quality by increasing access to care in integrated delivery systems; managed care and physician referrals; managed care and patient-physician relationships; cost-effectiveness of preventive services for older adults; fluoridation effects on oral health and dental demand; financial incentives and dentist adoption of preventive technologies; effects of dental insurance on dental demand, and the link between mother and child access to dental care.

Payment Reform Evaluation Project: Lessons from State and Regional Payment Reform

This project, funded by the Robert Wood Johnson Foundation (Douglas Conrad, PI; David Grembowski, Co-PI), will perform cross-cutting evaluation of eight payment reform efforts designed to promote high-value health care outcomes through leveraging existing market knowledge, partnerships and resources in different states and regions of the United States.

Physician Networks and Children with Chronic Conditions

Funded by the Agency for Health Care Research and Quality. For children with asthma or diabetes, the purposes of this study are to examine whether out-of-network benefits and cost-sharing of managed health plans are associated with the likelihood of seeing an in-network vs. out-of-network physician, and secondly, to examine whether health quality and expenditures are similar or different for children seeing in-network vs. out-of-network physicians.

Linking Mother and Child Access to Dental Care

In Washington state's Medicaid population of children aged 3-6 years old, the aim is to determine whether having a mother with a regular source of dental care is associated with greater utilization of dental care and oral health in children in four racial/ethnic groups: White (non-Hispanic), Hispanic, African American, and other groups. Funded by the National Institute of Dental and Craniofacial Research.

Caries Prevention Study

Although new, effective technologies have emerged for controlling caries in children, only a minority of dentists have adopted them. A randomized trial is being conducted to determine whether financial incentives and provider education can increase dentist adoption of these technologies, and in turn, whether adoption results in reduced caries incidence and restorative services among at risk children with capitation dental insurance. Funded by NIDCR and Washington Dental Service.

Improving Access to Improve Quality: Evaluation of an Organizational Innovation

Funded by the Robert Wood Johnson Foundation, the study is an evaluation of Group Health Cooperative's "Access Initiative." This innovation includes offering patients same-day appointments to primary care physicians, allowing them direct access to most specialists, and providing physicians with a $40 million clinical information system that offers up-to-the-minute patient health information. The study will determine how the initiative affects factors such as cost, utilization of services, quality of care, member enrollment, and patient and provider satisfaction.
