Ambulatory Care Sensitive Conditions (ACSC)
Conditions that respond to timely and effective care in the outpatient (ambulatory) setting. ACSC's are used as Prevention Quality Indicators, and can assist in evaluating quality or use of primary health care.
Formula = [The number of ACSC's discharges (or ER visits) / The total number of discharges (or ER visits)] * 100
While primarily intended for application to hospital inpatient data, we have applied to ER Visit data as well.

1 – Procedure codes: For ICD9, not all records used ICD9 procedure codes.

Please note: Some records may have more than one ACSC, in which case the first discovered is reported.

Cause of Discharge/ER Visit
Causes are based on the principal diagnosis, except in cases where an External (E-code) cause supersedes the principal diagnosis. All discharges having external causes (injuries) are assigned their appropriate valid External Cause of Injury Code (E-Code) in accordance with STIPDA (State and Territorial Injury Prevention Directors Association) 2003 guidelines. The standards can be found at:
Discharges/ER Visits
The number of inpatients discharged/ER Visits from non-Federal acute-care inpatient facilities. Only discharges/visits of Georgia residents who were seen in a Georgia facility are included. Persons can be counted more than once if readmitted. Causes are based on the principal diagnosis, except in cases where an External (E-code) cause supersedes the principal diagnosis. Discharges/visits include people both living and who have died.
Hispanic or Latino includes persons of Mexican, Puerto Rican, Cuban, South or Central American, or other Spanish culture or origin, regardless of race.
International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM)
A statistical classification system, in use since 1979, that arranges diseases and injuries into groups according to established criteria. It is used to improve comparability of cause of death statistics reported by different governmental entities. Most ICD-9-CM codes are numeric and consist of three, four or five numbers and a description. The codes are revised approximately every 10 years by the World Health Organization and annual updates are published by the Health Care Financing Administration (HCFA), now the Center for Medicare, Medicaid Services.
International Classification of Diseases, 10th Revision, (ICD-10)
An alphanumeric coding scheme that replaces ICD-9, and used for discharge/er visit data since the 4th quarter of 2015. ICD-10 codes were developed by the World Health Organization Collaborating Centres for Classification of Diseases.
An age year grouping methodology based upon predictable mortality. Georgia uses the following Lifestages: <1 Infancy, 1-4 Early Childhood, 5-12 Later Childhood, 13-19 Adolescence, 20-29 Early Adulthood, 30-44 Young Adulthood, 45-59 Middle Adulthood, 60-74 Late Adulthood, and 75+ Older Adulthood. The highest value for age is 120 years.
Any county with 35,000 or more total population per year 2000 Census.
Payor is the primary entity responsible for payment of services. Values for Payor include:
Percent ACSC Discharges/ER Visits
Formula = [The number of ACSC's discharges (or ER visits) / The total number of discharges (or ER visits)] * 100
Per the Federal Office of Management and Budget, Directive 15 (1997),

Note: Rates for years prior to year 2000 use population estimates for the denominator that adhere to a different Federal standard for race: White, Black, Asian or Other Pacific Islander, American Indian and Alaska Native. So, unlike years 2000 and after, Multiracial is not included. Also, Asian by itself is not available because it was grouped with Pacific Islander (After 1999 Asian is separate from Native Hawaiian or Other Pacific Islander).

Rates using Census Population Estimates in the denominator are not calculated when a selected race is not available in the denominator, or zero.

Nevertheless, selections available in OASIS' Race query box reflect the 1997 Race classifications described above. Most of the numerators used in indicators in Oasis *do* have the year 2000 race selections. Therefore, selections of multiple years that span <2000 and 2000+ will return a *number (count)* for all race selections, but the *rates* may be limited by the change in racial classifications the federal government used as noted above. In these cases you will see NA1 in the output cell (NA1 therefore by definition will only show up in rates for the years before 2000).

In some cases, the numerator's race classification may be more precise, or up to date, than the Census population estimate counterpart used in the denominator. You may find that there are a number of births of a given race for a county/age-group selection, but no count of population estimated for the denominator. In such cases where the race selection was available for both the numerator and the denominator, but the denominator's estimate was zero, you will see a NA2. If the numerator was greater than the denominator, but the denominator was > 0, you will see a NA3 returned.

Any county with less than 35,000 total population per year 2000 Census.
