|Data Elements for Emergency Department Systems - Release 1.0 (Centers for Disease Control and Prevention, 1997, 274 p.)|
|SECTION 1 - PATIENT IDENTIFICATION DATA|
Address of patient.
The address is useful for patient follow-up and billing. It also is used to determine the agency responsible for potential public health interventions and to link patient-specific data with census data so that incidence rates can be calculated. To protect patient privacy and confidentiality, access to this data element must be limited to authorized personnel.
This information probably is available from registration and billing record systems, in which addresses are routinely entered and stored.
Data Type (and Field Length)
XAD - extended address (106).
Yes, if the patient has more than one address.
Component 1 is the street address.
Component 2 is the second line of the address (e.g., apartment number).
Component 3 is the city.
Component 4 is the state or province.
Component 5 is the zip or postal code.
Component 6 is the country.
Component 7 is the type of address (e.g., mailing).
Component 8 is another geographic designation (e.g., catchment area ID).
Component 9 is the county/parish code.
Component 10 is the census tract.
Component 1 = 10 Ash Lane
Component 2 = Apt 3
Component 3 = Lima
Component 4 = OH
Component 5 = 48132
Component 9 = 019
Enter " " in Component 1 if the patient has no address, and enter Unknown in Component 1 if the patients address is not known. In either instance, restrict entries to Component 1. If individual address components are not part of the address (e.g., Component 3 for a rural address without a city designation), enter " ", and if individual components are not known, enter Unknown.
The county/parish code serves a variety of purposes and when used should be entered in Component 9 as the 3-digit Federal Information Processing Standards code. The default values for entries in Components 6 and 7 are USA and M for mailing address (see the definition of XAD in the Technical Notes at the end of this document). Entries should be made in Components 8 and 10 on the basis of local needs.
