Revision policy and significance of Basic Outcome Master (BOM) version 3.0

Abstract

　Basic Outcome Master (“BOM”) version 3.0 has been published. Its most important feature is its links with the Medical Information System Development Center (“MEDIS-DC”), the Nursing Practice Term Standard Master Nursing Observation (“MEDIS Nursing Master”) and version 10/11 of the Japan Laboratory Code (“JLAC”). These links have dramatically improved standardization among items subject to BOM observation. By aggregating identical structures, representation types (e.g., numerical, enumerative, etc.), result values and results, etc., MEDIS Nursing Master both significantly improves input format accuracy and reduces ambiguities in variance recognition, enabling clean data collection. This structure can be said to form an important element of the Outcome-AssessmentTask (“OAT”) unit—conceived as a basic data unit for use in medical processes. As the daily clinical pathway (hereinafter referred to as the “daily path”) is the collection of OAT units over 24-hour periods, BOM version 3.0 also functions as a safety management tool by improving the user interface of the daily path and adding easy-to-use identification and notification functions when an item under observation strays outside the proper range. The electronic structure of the term master is considered to have a relationship of outcome name-observation item name = 1: n, observation item name-nursing care name = 1:1, thereby smoothing interactions between the clinical path and nursing records. Using BOM version 3.0, it is possible to create a versatile path consisting of a basic OAT unit regardless of the specific nature of the disease or pathological condition, and a minimally required OAT unit according to the specificity of a certain disease or pathological condition. Accumulating big data from this versatile path will contribute to the stratification of complex diseases and pathological conditions.
