OASIS Mapping Tool - Emergency Room (ER) Visit Statistics

OASIS (Online Analytical Statistical Information System) is a suite of tools used to access the Georgia Department of Public Health's standardized health data repository.

• Create maps of ER visit counts and rates by age, race, sex, cause, payor, county and census tract for 2002-latest year available.
• Multiple selections can be made by holding down the Control or Shift keys.
• The source of this information is billing data (as captured on UB04 forms) provided by the Georgia Hospital Association. The data reflect Georgia residents who were seen in an acute care, non-federal hospital in Georgia. Therefore Georgia residents who were discharged from an out-of-state hospital are excluded. Causes are based on the principal diagnosis, except in cases involving an injury. ER Visits are reported by date of discharge, not admitting date.
• ICD10-CM was adopted on October 1, 2015 to report diagnoses.
