Delta (DLT) -- HL7v2 composite data type.

Specifies delta check parameters for observation values.

4 components:

  1. Normal Range (NR) -- sub-components (low & high)
  2. Numeric Threshold (NM)
  3. Change Computation (ID) -- percent, absolute
  4. Days Retained (NM)

Summary

Types

t()

Functions

encode(dlt)

Encodes a DLT to a list of component strings.

parse(components)

Parses a DLT from a list of components.

Types

t()

@type t() :: %HL7v2.Type.DLT{
  change_computation: binary() | nil,
  days_retained: binary() | nil,
  normal_range: HL7v2.Type.NR.t() | nil,
  numeric_threshold: binary() | nil
}

Functions

encode(dlt)

@spec encode(t() | nil) :: list()

Encodes a DLT to a list of component strings.

Examples

iex> HL7v2.Type.DLT.encode(%HL7v2.Type.DLT{numeric_threshold: "5", change_computation: "P"})
["", "5", "P"]

iex> HL7v2.Type.DLT.encode(nil)
[]

parse(components)

@spec parse(list()) :: t()

Parses a DLT from a list of components.

Examples

iex> HL7v2.Type.DLT.parse(["2.5&10.0", "5", "P", "7"])
%HL7v2.Type.DLT{
  normal_range: %HL7v2.Type.NR{
    low: %HL7v2.Type.NM{value: "2.5", original: "2.5"},
    high: %HL7v2.Type.NM{value: "10", original: "10.0"}
  },
  numeric_threshold: "5",
  change_computation: "P",
  days_retained: "7"
}

iex> HL7v2.Type.DLT.parse([])
%HL7v2.Type.DLT{}
