What is data linkage and how does it relate to CPCSSN?

Linking data allows for more exhaustive data sets and can enable research involving multiple variables that cannot be researched with one data source alone. CPCSSN has linked CPCSSN-collected electronic medical record data with complementary administrative health data so that complex conditions involving many variables can be researched. For example, a CIHR-funded study is examining frailty among elderly adults, which requires information on several physiological functions (e.g. blood pressure) in addition to information on the use of health care services (e.g. hospitalizations). Data linkages must be conducted within each regional network and may not feasible in all networks.
