Health Services Research studies

Our health services research focuses on the delivery and outcomes of medical care. Our research crosses a range of areas, with a focus on primary and secondary prevention services for chronic diseases, such as diabetes and cardiovascular disease. Our studies have assessed health care initiatives targeting the care and behavior of patients at high risk for these conditions.

High blood pressure can be missed in patients who do not have regular visits with their primary care provider. The goal of the present project is to estimate the efficacy of blood pressure assessments in specialty clinics. We will compare recognition, follow-up, and time-to-treatment between patients first recognized in specialty care to those in primary care.

The Virtual Visit for Women with Gestational Diabetes Mellitus (GDM)

This pilot study will address two specific aims: (1) to assess the acceptability of telemedicine technology to conduct virtual office visits alternating with regular office- based prenatal visits for women with GDM from the viewpoint of women with GDM and their health care providers using qualitative research methods, and (2) to assess the feasibility of this telemedicine-based intervention (Virtual Office Visit) for women with GDM. This information was be used to support a larger proposal to obtain funding to conduct a clinical trial to test the proposed intervention after it is refined based on input from patients and health care providers.
