Data Quality Documentation for the Ontario Chronic Care Patient System (OCCPS)

Purpose of Data Quality Documentation This document has four major objectives. First is to provide background information on the Ontario Chronic Care Patient System (OCCPS) and the assessment instrument upon which it is based, InterRAI MDS 2.0©. Second is to provide insight and guidance regarding database structure, Table linkages, and the development of flat files for analyses. Third is to provide sufficient information to allow users to decide whether the quality of the OCCPS data is appropriate for its intended use. In particular, this document will flag and explain data quality issues relevant to analysis and interpretation. Last, it will inform users of the data quality improvements expected as a consequence of OCCPS conversion to the Continuing Care Reporting System (CCRS).
