Abstract

ABS carries clinical abstracting data for a patient encounter. It includes the discharge care provider, severity of illness, triage code, case category, and newborn-related fields such as gestation period and stillborn indicator. It supports quality reporting and clinical data abstraction.

The severity_of_illness_code field uses CWE with HL7 table 0421:

from zato.hl7v2.v2_9 import ABS, CWE

abs_seg = ABS()
abs_seg.severity_of_illness_code = CWE(
    identifier='MI',
    text='Minor',
    name_of_coding_system='HL70421'
)

Use the gestation, newborn, and caesarian fields together:

from zato.hl7v2.v2_9 import ABS, CWE

abs_seg = ABS()
abs_seg.caesarian_section_indicator = 'Y'
abs_seg.gestation_category_code = CWE(
    identifier='FT',
    text='Full term',
    name_of_coding_system='HL70424'
)
abs_seg.gestation_period_weeks = '38'
abs_seg.newborn_code = CWE(
    identifier='SI',
    text='Single',
    name_of_coding_system='HL70425'
)
abs_seg.stillborn_indicator = 'N'

The discharge_care_provider field uses XCN with HL7 table 0010:

from zato.hl7v2.v2_9 import ABS, XCN

abs_seg = ABS()
abs_seg.discharge_care_provider = XCN(
    person_identifier='1234',
    family_name='DOE',
    given_name='JOHN',
    suffix='MD'
)

The triage_code field uses CWE with HL7 table 0422:

from zato.hl7v2.v2_9 import ABS, CWE

abs_seg = ABS()
abs_seg.triage_code = CWE(
    identifier='UR',
    text='Urgent',
    name_of_coding_system='HL70422'
)

Zato connects to any system that speaks HL7v2 over MLLP or FHIR over REST. This includes Epic, Cerner, Meditech, Allscripts, and other EHR platforms.

Yes, Zato has built-in MLLP support for sending and receiving HL7v2 messages. MLLP channels handle the framing protocol automatically.

Zato supports HL7 v2.9, which is backward compatible with earlier versions including v2.3, v2.5, and v2.7. Standard segments and datatypes are available as typed Python classes.

Yes. Zato handles both HL7v2 and FHIR natively, so you can parse v2 messages and build FHIR resources with IG-specific extensions in the same service. Typed Python classes are available for both protocols, including extensions from US Core, UK Core, Da Vinci, and other Implementation Guides.
