METHODS
The Institutional Critical Care Committee approved and supported the METRIC Data Mart project. Mayo Clinic Institutional Review Board (IRB) approval is required for specific research studies using METRIC Data Mart.
The Mayo Clinic campus in Rochester, MN, is an academic medical center with 1900 beds and 135,000 hospital admissions per year. The combined capacity of the ICUs is 204 beds and 14,800 admissions per year. Saint Marys Hospital has 183 ICU beds: 24 general medical, 16 medical
RESULTS
Data sources, metadata, and frequency and timeliness of updates for individual categories of data available within the METRIC Data Mart are described in Table 1. A “demo” table contains all demographic information and serves as the main index for ICU admissions. The combination of the patient's medical record number and the time of ICU admission serves as a unique identifier in the database.
Table 2 lists the results of random sample validation by manual record review for each specific category
DISCUSSION
With implementation of a comprehensive EMR at our institution, an opportunity arose to construct and validate the METRIC Data Mart, a custom, near real-time data warehouse.
After an Institute of Medicine Report19 highlighted an unacceptable rate of medical errors in hospitalized patients, the National Institutes of Health Roadmap called for the urgent support of patient safety initiatives, quality improvement, and translational outcome research. All these initiatives are facilitated by a
CONCLUSION
The METRIC Data Mart provides a novel informatics infrastructure for the extraction of ICU data from a hospital EMR into an open, integrative database. With the inevitable arrival of the EMR in hospital practice, the availability of an appropriately designed and implemented resource, such as that described in this study, will become an essential requirement for the conduct of activities such as process control, reporting, syndrome surveillance, decision support, and outcome research in the ICU.
