The STOR Data Warehouse is available for research use beginning February 1, 2018.

STOR was the primary Electronic Health Record for UCSF between 1988 and 2005, and was used by many providers between 2005 and the APeX go-live on 6/1/2012.  STOR was one of the first electronic health record systems in the United States. As a result, it provides an invaluable longitudinal history of a patient's disease spanning up to 40 years, when combined with APeX data.

STOR is a rich source of patient information for research. STOR was designed by and for physicians so it focuses on capturing the most relevant patient information to guide clinical decision making. Full-text clinical notes were dictated by STOR providers and later transcribed into the system by support staff. Problems were coded by providers in a hierarchical form that could be specific to each department.

In addition, STOR captured and saved, through HL7 feeds, clinical information originating from other UCSF including visits from IDX, lab results, procedure codes from billing, and SNOMED codes from Pathology.
