Abstract

The primary goal of this project is to create and evaluate an Internet-based “Comparative Effectiveness Research Hub” (CER Hub) where researchers can collaboratively develop standardized problem-specific processors of electronic clinical data (with medical classifier applications, or MediClass) in support of CER studies. The project aims to develop a platform for CER with the capacity to generalize along dimensions to function in any EMR data environment, to integrate health care information from diverse settings and clinical practices, and to address any CER questions where both free text and coded EMR data would be required. The project team is a consortium of researchers from 6 diverse health systems assembled to answer key CER questions in asthma control therapy and smoking cessation care delivery. For more information, visit www.cerhub.org.

Infrastructure Aims

1. Create and evaluate a platform for collaborative development and conduct of healthcare research and quality studies that use distributed, heterogeneous, electronic clinical data; and

2. Make a proven natural language pro­cessing (NLP) technology broadly available for enhancing use of EMR data.

Primary Research Aims

Research projects using CER Hub tech­nologies are formed as investigator-led communities focused on CER. Current projects include observational analy­sis of heterogeneous clinical data for asthma control therapy and smoking cessation care delivery.

Healthcare Settings

Primary care or ambulatory clinics, Inpatient facilities

Geographic scope type

National

Locations of Focus

multiple regions across the US. Areas covered by the network include the states of Georgia, Hawaii, Oregon and Washington; the city of Houston, TX; and the region of southern California (Bakersfield to Los Angeles)

Population Network Size

1,982,300 patients

Informatics Platform/Tools

Centralized web platform with distributed processors of heterogeneous data. Data model is derived from HL7 Clinical Document Architecture. Distributed data processor is built from the MediClass medical record processing engine. The MediClass system (a “Medical Classifier”) incorporates natural language processing and knowledge based systems technologies to automatically code clinical data of all types to address many CER questions. The system uses an emerging standard for representing the complete medical record; therefore data from any EMR implementation can be uniformly processed.
