Washington Heights/Inwood Informatics Infrastructure for Community-Centered Comparative Effectiveness Research (WICER)
The WICER project advances comparative effectiveness research (CER) through creating a robust community-focused data infrastructure that supports innovative studies of public health problems. WICER is built on an existing institution-focused data foundation at Columbia University. WICER contains a research data warehouse that integrates patient-level data, including clinical data from multiple facilities, settings and sites of care, with person-level self-reported information collected via community survey. It maps the linked data to variables that support CER studies. WICER also includes tools to support researchers in accessing WICER data resources to perform retrospective analyses and recruit patients for research studies. Three CER studies demonstrating the WICER infrastructure and methods are prospectively studying the diagnosis, treatment and management of hypertension.
Create a robust community-focused data infrastructure including a research data warehouse that integrates patient-level data with person-level self-reported information from a community based survey in a predominantly low-income, minority neighborhood in New York City, a Research Data Explorer (RedX) tool to support data queries, and EHR “plug-ins” to facilitate research tasks in the context of clinical care processes. CER studies focus on hypertension diagnosis, treatment, and management.
This project will create the following four elements:
1. De-identified research warehouse, which will integrate health care data from multiple disparate data sources, plus community survey data, together in a research data warehouse (RDW) have the option to incorporate additional data during the course of the project if appropriate IRB applications are completed (e.g. dental/ oral health information);
2. Research Data Explorer (RedX), a front-end viewer to the de-identified data in the RDW. This allows researchers to browse patient data to look for specific data elements that can be used to generate research queries (identified as a critical component of query creation through years of experience providing mediated queries);
3. Agile, portable, ready to implement research decision support tools (i.e., EHR “plug-ins”) that can flexibly work with EHRs to facilitate research tasks in the context of clinical care processes;
4. Data governance policies and procedures
Primary care or ambulatory clinics, Inpatient facilities, Academic medical centers, Community health centers, Long-term care facilities, Community households
Electronic Health/Medical Records (EHR or EMR), Patient-Reported Outcomes
