i2b2: Informatics for Integrating Biology and the Bedside

The Center for Biomedical Informatics and Biostatistics (CB2) has implemented the open source software, i2b2, which was initially developed by Partners HealthCare System and has been widely adopted by many academic medical centers. It allows researchers to formulate “and/or” queries using a graphical web based tool and returns counts of patients matching the query. This can be helpful in assessing the feasibility of clinical trials, refining research questions and familiarizing yourself with the data currently available through the Clinical Data Warehouse.
