Clinical Information System Impact on Hospitalized Patients With Chronic Disease

Starting soon

Conditions studied: Diabete Mellitus, Kidney Disease, Heart Failure, Coronary Artery Disease, Chronic Lung Diseases

In brief

This is a retrospective, observational study using routinely collected information collected by Alberta Health Services. The study will identify patients with chronic disease, defined by one or more of the following conditions; diabetes mellitus, heart failure, coronary artery disease, chronic kidney disease, or chronic lung disease. Adult residents of Alberta with a chronic disease of interest present upon hospital admission and who survive to hospital discharge will be included in the study cohort. The primary outcome will be the composite of hospital readmission or death within 30 days of discharge. Secondary outcomes will include components of the composite, length of stay, patient experiences related to their hospital to home transition of care, and processes of care. Multi-level interrupted time series analysis will be used to compare outcomes before versus after implementation of the Connect Care CIS.
