CRN Pilot: Are 2 Jars Sufficient for Pathology Examination of Extended Core Prostate Biopsy?
The methodology for submitting extended core prostate biopsy (ECPB) varies widely with no currently recommended approach. Urologists may process tissue cores into between two and twelve jars, a difference that can result in a variance of up to $1000 in costs to insurers. This pilot study examines the patterns of ECPB tissue cores processing to determine associations between number of jars and key outcomes (e.g.: rates of prostate cancer detection, equivocal diagnoses) - within two Cancer Research Network sites that have mixed insurance and practice patterns.

CRN4: Cancer Research Resources & 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, the 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 is 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 will directly support pilot projects that may be initiated either by non-CRN-affiliated investigators or by CRN investigators.

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.

Improving Diabetes Quality Reports for Persons with Multiple Chronic Conditions
The aim of this developmental work is 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 will be retrospective data from the pool of subjects with diagnosed diabetes.

Sentinel Project: Workgroup Activities for Task Order 7 (20 Potential Exposure/Outcome Associations)
This Task Order seeks to use the tools, resources and data environments of the Sentinel system to examine potential associations of exposures to a drug with specified adverse outcomes under several sets of conditions. This SOW provides support to run standard work plans for workgroup activities funded under this Task Order for up to 20 exposure outcome pairs.

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.

Wisconsin NCI Community Oncology Research Program (WiNCORP)

A consortium between Marshfield Clinic Health System, Gundersen Health Systems, and St. Vincent Regional Cancer Center, WiNCORP’s overarching goal is to provide access to NCI-sponsored clinical trials to over 680,000 community members residing within a collective, largely rural service area spanning most of the state of Wisconsin, upper Michigan, and adjacent counties in Iowa and Minnesota. WiNCORP was among only 14 of 40+ NCORP community sites to be selected for enhanced Cancer Care Delivery Research as part of network activities.

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.

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.

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.

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.
