The Greater Plains Collaborative
This work as one of PCORI’s 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 ALS, breast cancer, and weight/obesity that can be characterized and surveyed in support of future research.

The Sentinel Initiative: Detection and Analysis of Adverse Events Related to Regulated Products in Automated Healthcare Data
This public health surveillance project uses automated health care data across 19 health care organizations with many millions of covered lives to evaluate post market medical product safety, providing the FDA with the ability to analyze information collected during the course of routine health care, such as data from electronic health record systems, administrative and insurance claims databases and medical registries.

RIC: Risk of Pediatric and Adolescent Cancer Associated with Medical Imaging
The broad goal of the Radiation Induced Cancer (RIC) study is to evaluate patterns of medical imaging in pregnancy and pediatrics, cumulative exposure to radiation, and subsequent risk of childhood cancer. To achieve this goal, we are conducting a retrospective, nested case-control study of patients enrolled in 8 integrated health care systems. To view publication: click here

The Effectiveness, Safety, and Costs of Guideline-Concordant Lung Nodule Care
The aims of this 2-site observational study in the Cancer Research Network are to evaluate individuals who receive varying intensities of diagnostic evaluation for an incidentally detected lung nodule and compare rates of early stage lung cancer, harms, and costs of care.

Recently Completed Projects:

Abstracting Device Settings for Comparative Effectiveness of Single vs. Dual Chamber ICDs
This study abstracted implantable cardioverter defibrillator device settings to support comparative effectiveness research studies of single vs. dual chamber ICDs within a large cohort of patients with left ventricular systolic dysfunction undergoing ICD implantation for primary prevention of sudden cardiac death at seven large health systems within the Cardiovascular Research Network (CVRN).

RN4: Cancer Research Resources and Collaboration in Integrated Health Care Systems
The Cancer Research Network (CRN) is a consortium of research organizations within several non-profit health care delivery systems. The uniqueness of CRN as a cancer research resource stems from: (1) the integrated access to clinical data for large, stable, and diverse patient populations that are available through the "parent" HMOs; and (2) the expertise of CRN researchers in conducting clinical cancer research involving large sets of clinical data. Through this, NCI intends to promote further technical and methodological enhancements of CRN informatics infrastructure as well as efforts to facilitate access of non-CRN-affiliated investigators to CRN data and expertise. The goal was to increase the number and scope of research projects that are based on CRN data and the participation of CRN investigators on such projects. In addition to collaborations on projects funded outside of CRN, CRN directly supports pilot projects that may be initiated either by non-CRN-affiliated investigators or by CRN investigators.

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.

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.

Longitudinal Studies of Implantable Cardiac Defibrillators (ICDs)
The objective of this study was to evaluate the clinical and device therapy outcomes among patients with left ventricular systolic dysfunction undergoing ICD implantation for primary prevention of sudden cardiac death at seven large health systems within the Cardiovascular Research Network (CVRN).

Mini Sentinel Project: Thromboembolic Events After Immunoglobulin Administration
The Blood Safety Continuous Active Surveillance Network (Blood-SCAN) is a Task Order under the Mini Sentinel pilot that aimed to develop a claims-based active surveillance system for FDA-regulated blood components and blood-derived products. As part of the Blood-SCAN activities, we conducted a one-time, retrospective protocol-based assessment of thromboembolic events (TEE) after immunoglobulin administration and validated the algorithms used to identify the exposure and the outcome. There are 13 different FDA approved products of interest. The majority of Ig use is via the intravenous route (IV), though some products are available for intramuscular (IM) or subcutaneous (SC) administration.
