SPARCS is a comprehensive all payer data reporting system, initially created to collect information on discharges from hospitals. SPARCS currently collects patient level detail on patient characteristics, diagnoses and treatments, services, and charges for each hospital inpatient stay and outpatient (ambulatory surgery, emergency department, and outpatient services) visit; and each ambulatory surgery and outpatient services visit to a hospital extension clinic and diagnostic and treatment center licensed to provide ambulatory surgery services. SPARCS offers three levels of data access: public, limited, and identifiable. Public use data is openly available. Limited or identifiable data requires the submission of an application.
