This is how we do it. I would do it more cleanly if I were to write this
again now, but this should point you in the right direction:
- We have individual classes to store the data we care about from
each segment (see later)
- We try to get a segment from the message
- If the message is not there, we just throw an exception, ignore
and continue
protected HL7Record(Message Msg)
throws DataTypeException, HL7Exception
{
try
{
_PID = new HL7PID((PID)Msg.get("PID"));
}
catch (HL7Exception E) { }
try
{
Segment segment = (Segment)Msg.get("PV1");
if (segment != null)
_PV = new HL7PV((PV1)segment, (PV2)Msg.get("PV2"));
}
catch (HL7Exception E) { }
try
{
Structure[] Structs = Msg.getAll("DG1");
if (Structs != null && Structs.length > 0)
{
_DG1 = new HL7DG1[Structs.length];
for (int i = 0; i < Structs.length; ++i)
_DG1[i] = new HL7DG1((DG1)Structs[i]);
}
}
catch (HL7Exception E) { }
try
{
Structure[] Structs = Msg.getAll("INSURANCE");
if (Structs != null && Structs.length > 0)
_IN1 = new HL7IN1(Structs);
}
catch (HL7Exception E) { }
try
{
Structure[] Structs = Msg.getAll("AL1");
if (Structs != null && Structs.length > 0)
_AL1 = new HL7AL1(Structs);
}
catch (HL7Exception E) { }
try
{
Segment s = (Segment) Msg.get("MRG");
if (s != null)
_MRG = new HL7MRG((MRG)s);
}
catch (Exception E) { }
}
And then, for an individual class, for example DG1, we do simple mappings:
public class HL7DG1
{
public final String _SetId ;
public final String _CodingMethod ;
public final String _Code ;
public final String _Description ;
public final HL7DTM _DateTime ;
public final String _Type ;
public final String _MajorCategory ;
public final String _RelatedGroup ;
public final HL7XCN _Clinician ;
public final String _Classification;
public final String _Confidential ;
public final String _Identifier ;
public HL7DG1(DG1 Diagnosis)
throws DataTypeException, HL7Exception
{
/*DG1-1: Set ID - DG1 (SI) */ _SetId
= Diagnosis.getSetIDDG1().getValue();
/*DG1-2: Diagnosis Coding Method (NULLDT) optional */
_CodingMethod = Diagnosis.getDiagnosisCodingMethod().getValue();
/*DG1-3: Diagnosis Code - DG1 (CWE) */ _Code
=
MakeSureItsAlright(Diagnosis.getDiagnosisCodeDG1().getIdentifier().getValue(
), _CodingMethod);
/*DG1-4: Diagnosis Description (NULLDT) optional */ _Description
= Diagnosis.getDiagnosisDescription().getValue();
/*DG1-5: Diagnosis Date/Time (DTM) optional */ _DateTime
= new HL7DTM(Diagnosis.getDiagnosisDateTime());
/*DG1-6: Diagnosis Type (IS) */ _Type
= Diagnosis.getDiagnosisType().getValue();
/*DG1-7: Major Diagnostic Category (CNE) optional */
_MajorCategory =
Diagnosis.getMajorDiagnosticCategory().getIdentifier().getValue();
/*DG1-8: Diagnostic Related Group (CNE) optional */
_RelatedGroup =
Diagnosis.getDiagnosticRelatedGroup().getIdentifier().getValue();
/*DG1-9: DRG Approval Indicator (ID) optional */
/*DG1-10: DRG Grouper Review Code (IS) optional */
/*DG1-11: Outlier Type (CWE) optional */
/*DG1-12: Outlier Days (NM) optional */
/*DG1-13: Outlier Cost (CP) optional */
/*DG1-14: Grouper Version And Type (NULLDT) optional */
/*DG1-15: Diagnosis Priority (ID) optional */
/*DG1-16: Diagnosing Clinician (XCN) optional repeating */ _Clinician
= new HL7XCN(Diagnosis.getDiagnosingClinician(0));
/*DG1-17: Diagnosis Classification (IS) optional */
_Classification = Diagnosis.getDiagnosisClassification().getValue();
/*DG1-18: Confidential Indicator (ID) optional */
_Confidential = Diagnosis.getConfidentialIndicator().getValue();
/*DG1-19: Attestation Date/Time (DTM) optional */
/*DG1-20: Diagnosis Identifier (EI) optional */ _Identifier
= Diagnosis.getDiagnosisIdentifier().getEntityIdentifier().getValue();
/*DG1-21: Diagnosis Action Code (ID) optional */
/*DG1-22: Parent Diagnosis (EI) optional */
/*DG1-23: DRG CCL Value Code (CWE) optional */
/*DG1-24: DRG Grouping Usage (ID) optional */
/*DG1-25: DRG Diagnosis Determination Status (IS) optional */
/*DG1-26: Present On Admission (POA) Indicator (IS) optional */
}
}
What I have found to be the biggest pain is to figure out if the data is in
x.getValue(), or x. getIdentifier().getValue() etc. Additionally, again, I
would do it a bit differently today and make this a lot more flexible by
using the basic parser and access fields with HL7 "paths" J

That would be really great for me.
Appreciate your reply and time for the same.
