Description
The National Ambulatory Care Reporting System (NACRS) is a tool for collecting data and reporting on all levels of ambulatory care within Canada including emergency departments (EDs), day surgery, and medical and surgical day clinics within hospitals, the community and private clinics. NACRS facilitates comparisons and benchmarking across jurisdictions provincially and nationally through the use of standardized definitions and coding standards that adhere to national and international standards.
In September 2010 the BC Ministry of Health (the Ministry) mandated the health authorities to work with Canadian Institute for Health Information (CIHI) to implement the NACRS Level 2 at fifteen high volume emergency departments across the province. NACRS Level 2 will provide patient level, demographic and wait time information and clinical data including presenting complaint and discharge diagnosis. Presently there are a total of twenty-nine hospital EDs in the province reporting to NACRS and no ambulatory care facility is reporting in BC.
