Building CER Capacity: Aligning CRN, CMS, and State Resources to Map Cancer Care – Research on the effectiveness of advanced cancer treatments (REACT)
Research on the effectiveness of advanced cancer treatments (REACT)
Through a partnership between investigators in the Cancer Research Network (CRN) and Dana-Farber/Harvard Cancer Center, the goal of this American Recovery and Reinvestment Act of 2009 and NCI sponsored Grand Opportunity grant titled “Building CER Capacity: Aligning CRN, CMS, and State Resources to Map Cancer Care – Research on the effectiveness of advanced cancer treatments (REACT),” was to develop a resource to support high quality cancer comparative effectiveness research (CER) by addressing two key knowledge gaps -- treatment of advanced disease, and population-based research on patterns and outcomes of cancer care for patients who are not represented in SEER-Medicare. While capitalizing on pre-existing infrastructure, we focused our activities to selectively enhance and create a sustainable resource to support CER studies in patients with advanced cancer by addressing the following aims:
Aim 1. Build broad capacity by assembling national data sets (CRN, SEER-Medicare, Medicaid, and NCCN) to support studies of patterns of care and outcomes among patients with advanced cancer and developing, validating, and implementing strategies to enhance the accuracy of key data elements;
Aim 2. In one region (California) augment the patient level data from the national sources in Aim 1 with regional data on supply to build a comprehensive cancer “map” of the region;
Aim 3. Test capacity and understand limitations of the data systems assembled in Specific Aims 1 and 2 by conducting 5 “use case” analyses that describe patterns of care for select decisions in advanced cancer that span the major treatment modalities, have significant clinical or economic ramifications, and are likely influenced by patient, provider, and/or health system factors; and
Aim 4. Launch comparative effectiveness analyses that capitalize on the resources developed and tested in Aims 1-3 by (a) conducting analyses to fully determine the CE of two interventions for advanced cancer, (b) designing and vetting a CE trial appropriate for the CRN, and (c) partnering with NCI to convene a national stakeholders meeting where project data will be presented and strategies for future CER research in cancer discussed.
Our project recruited both MD and PhD investigators (senior and junior) and trainees from Dana –Farber Cancer Institute (DFCI), Harvard University, and the CRN to utilize the infrastructure we developed, and to conduct studies of patterns of care and CER analyses related to the treatment of advanced disease. Our strategy to assemble multiple national datasets from sources that include registry-linked Medicaid data, tumor registry data, CRN based electronic medical record (EMR) and claims data, SEER-Medicare linked data, and data from the Cancer Care Outcomes Research and Surveillance (CanCORS) Consortium project, allowed us make substantial progress in developing and testing the infrastructure to support CER of advanced cancer. We have used this infrastructure to conduct several focused analyses, frequently juxtaposing the data sources to enable meaningful comparisons and also allowing us to identify variations in the patterns and predictors of treatment and outcomes. In addition, we conducted several CER analyses associated chemotherapy and radiotherapy.
EHR/EMR System or Vendor
Primary care or ambulatory clinics, Inpatient facilities, Emergency departments, Specialty clinics, Academic medical centers
Electronic Health/Medical Records (EHR or EMR), Diagnostic data, Pharmacy databases, Claims, Patient Registries, Data Collected for Independent, Research Studies (e.g. clinical trial, longitudinal outcomes study)
Geographic scope type
Locations of Focus
We used EHR/EHR and other administrative data from four of the 9 integrated HMOs that are members of the Cancer Research Network (CRN): Kaiser Permanente Northern California (KPNC), KP Colorado (KPCO), KP Northwest (KPNW); and Group Health (GH). This four plans cover more than 5 million individuals. In addition, we also used data from the SEER-Medicare data link which contained information on 105,000 incident cancer cases diagnosed in 2005 and longitudinal claims data characterizing care are available for the approximately 80% of Medicare beneficiaries enrolled in fee-for-service plans. Cancer Registry and Medicaid enrollment data from the states of California and New York were included in several of the analyses along with primary data that was collected at 21 cancer centers across the US who participate in the National Comprehensive Cancer Network (NCCN).
