Currently Funded Projects:

Surveillance of Medically Attended Injuries in Farm Children
As part of the broader National Children's Center for Rural and Agricultural Health and Safety, this project will develop a regional platform for agricultural injury surveillance in children and adolescents who live on farms. Multi-year trends in agricultural injuries will be estimated and the highest risk population subgroups will be identified.

The Greater Plains Collaborative
This work as one of the Patient Centered Outcomes Research Institute's (PCORI) PCORNet Clinical Data Research Networks, involves 12 academic medical centers to: 1) create a research ready dataset of more than 1 million patients; 2) involve patients, providers, and health systems throughout the research process; 3) develop processes for practical, patient-centered clinical trials that are seamless with health care operations; and, 4) develop cohorts of patients in amyotrophic lateral sclerosis (ALS), breast cancer, and weight/obesity that can be characterized and surveyed in support of future research.

Understanding and addressing health disparities in Wisconsin through statewide partnerships.
The aims of this project in collaboration between Marshfield Clinic Research Institute, University of Wisconsin, Medical College of Wisconsin, Wisconsin Collaborative for Healthcare Quality, and Wisconsin Health Information Organization are to: 1) report on populations with disparities in health care access, quality, use, and outcomes in Wisconsin over time; 2) build and evaluate statewide capacity to enhance health improvement strategies with best practices that simultaneously reduce disparities; and, 3) facilitate partnerships to develop and amplify research to target disparities that lack evidence-based interventions.

Improving Diabetes Quality Reports for Persons with Multiple Chronic Conditions
The aim of this developmental work was to evaluate the utility of existing health care quality reporting data from 3 healthcare systems in Wisconsin to support a more meaningful assessment of health care quality for subjects with multiple chronic conditions. The specific target for this initial work was retrospective data from the pool of subjects with diagnosed diabetes.

Discharge Order Completeness and 30‐Day Re-hospitalizations in Rural Wisconsin Nursing Home Patients
Our long term objective was to improve hospital-to-nursing home discharge communication and thereby, improve nursing home patient safety. In pursuance of this goal and building upon our strong preliminary data, we proposed to determine the impact that discharge order omissions have on 30-day re-hospitalization in patients discharged from rural Wisconsin hospitals to nursing homes, and to identify how work processes and provider training levels in these hospitals influence discharge order communication.

Preparing to Prioritize CVD (Cardiovascular Disease) Strategies in Rheumatoid Arthritis and Lupus: P2P-CVD
In the general population, attributable risks have been critical to identify U.S. and global preventive care priorities. However, attributable risks in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are unknown. This study's objective was to help fill the critical knowledge gap of attributable risks for CVD and death in RA and SLE, to inform selecting the most important targets for a clinical intervention study to improve risk factor control and event-free survival.

CVRN-Risks with ICD Placement and Outcomes in Kidney Disease (CVRN-RISK) Study
The aims of this bridge award were: 1) to understand the extent to which patients with heart failure with reduced left ventricular ejection fraction and concomitant reduced kidney function receive guideline-based primary prevention ICDs (implantable cardioverter defibrillators) compared with patients with preserved kidney function; 2) to clarify the effect of kidney function level on complications, hospitalization and death among heart failure patients who do and do not receive an ICD.
