Diet tray instructions

ODT carries tray-level instructions for meal delivery, including the tray type (e.g. isolation, guest, pediatric), an optional service period, and free-text preparation notes. It accompanies ODS in diet order messages.

The tray_type field uses CWE with HL7 table 0160:

from zato.hl7v2.v2_9 import ODT, CWE

odt = ODT()
odt.tray_type = CWE(
    identifier='ISO',
    text='Isolation',
    name_of_coding_system='HL70160'
)

The service_period field uses CWE with HL7 table 0627 to indicate the meal time:

from zato.hl7v2.v2_9 import ODT, CWE

odt = ODT()
odt.service_period = CWE(
    identifier='DIN',
    text='Dinner',
    name_of_coding_system='HL70627'
)

The text_instruction field is a simple string for preparation and delivery notes:

from zato.hl7v2.v2_9 import ODT, CWE

odt = ODT()
odt.tray_type = CWE(
    identifier='ISO',
    text='Isolation',
    name_of_coding_system='HL70160'
)
odt.text_instruction = (
    'Use disposable utensils'
)

HL7 table 0160 defines tray types. Common values include isolation, guest, and pediatric trays:

from zato.hl7v2.v2_9 import ODT, CWE

odt = ODT()

# Isolation tray
odt.tray_type = CWE(identifier='ISO')

# Guest tray
odt.tray_type = CWE(identifier='GST')

# Pediatric tray
odt.tray_type = CWE(identifier='PED')

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.
