What’s new in HL7Spy 20.1?
Lots…
- We have made HL7Spy faster. We improved the performance of loading the application, loading messages, query messages, performing statistics calculations on a field, and many other aspects of the application.
- HL7Spy can handle more data. We have improved HL7Spy’s already unique ability to load 100’s of thousands of messages. In HL7Spy 2020.1 we have improved many features to handle the increased size of HL7 data streams. We have some customers that are loading 42,000,000 messages and running queries to generate reports. That’s a lot of messages!
Here is what its like to load 1.1 million messages from a 7-zip archive containing 10 files on a standard laptop.
Watch how fast it is when used to calculate the statistics on the MSH-9 field.
- We went through the entire product and improved every window and dialog in the application. We asked ourselves how we can make them better, and we did. Check it out for yourself.
- We added more options for saving the application layout, font sizing, opening behavior, saving/restoring application settings, and more.
- We added the ability to set the font size of the editor and most data grids within the application. This is great if your eyes are getting older like mine.
- We have updated all data grids, and tree grids in the application. Where useful, they now support searching, sorting, and data grouping.
- The HL7 Editor has been revamped. In v2020 it is snappier, renders text more precisely, handles large HL7 messages better, supports configurable field highlighting, and has a cool new search tool (shown below).
- The Custom Code Tool – This tool is for power-users! It is amazing what you can do if you know a little C#. In v2020 this tool has been completely redone. It now supports the .NET 4.8 run-time, and C# 7.x language specification.
- One of the great new features in HL7Spy v2020 is built for users who are migrating to a new HL7 Integration Engine, (like Rhapsody, or Corepoint –product plug intended). The Bulk Compare tool allows users to compare the output from their old integration engine with the output of their new one, to ensure that the outputs are equivalent before flipping the switch. The Bulk Compare Tool generates results that allow you to see exactly which messages and fields are different between two message streams. Statistics by message type and field are created. These results can be exported to PDF and Excel for reporting purposes.The Bulk Compare tool is fast, so fast. It can compare 100,000 messages in under 15 seconds. See it in action below.
- HL7 Sender/Receiver – Improved SSL/TLS support.
- Sql Loader tool – This tool has been updated for v2020.1 . We have also included for InterSystems Caché/IRIS. (Thank you to Jeff Drumm for his help us get this feature into v2020!). Please see his article on how to set this up in your environment: https://community.intersystems.com/post/load-ensemble-messages-hl7-spy-v20201
HL7Spy v4 Beta – Bulk Compare Tool
New – HL7Spy v4 is ready for Beta testing!
HL7Spy v3 was released in June 2017. Since that time we have released over 40 new versions of HL7Spy in response to customer requests for new features and to make bug fixes (many more improvements that bug fixes :)). We are now releasing a major upgrade to HL7Spy with some great enhancements.
One of the great new features in HL7Spy v4 is built for users who are migrating to a new HL7 Integration Engine, (like Rhapsody, or Corepoint –product plug intended). The Bulk Compare tool allows users to compare the output from their old integration engine with the output of their new one to ensure that the outputs are equivalent before flipping the switch.
The Bulk Compare Tool generates results that allow you to see exactly which messages and fields are different between to message streams. Statistics by message type and field are created. These results can be export to PDF and Excel for reporting purposes.
The Bulk Compare tool is fast, so fast. It can compare 100,000 messages in under 15 seconds. See it in action below.
The Bulk Compare tool was developed in conjunction with Rhapsody’s Co-Creation Labs: https://rhapsody.health/co-creation-lab. It was a great opportunity for us to work with the experts in the integration space and create a comprehensive HL7 integration engine migration tool. We were happy and impressed with the co-creation result and we think you will be too.
More information about the Bulk Compare tool can be found in the HL7Spy v4 user manual here: Bulk Compare Tool.
Send and Receive HL7
In this example we are demonstrating sending HL7 messages from one instance of HL7Spy to another. Look how fast it sends 100,000 messages!
HL7Spy supports sending and receiving HL7 using SSL.
Write Custom Code in C#
Power users can write custom code in C# to do almost anything the .NET framework will allow you to do. In this simple example we are appending the text “-test” to the existing value of MSH-3.
Included in HL7Spy are examples of how to de-identify patient information, generate messages, and other more complex message processing routines.
Select All Messages for a Patient
By right-clicking on an HL7 field you can easy to select all messages for a patient. HL7Spy will query all messages, find those that match, and present an ordered list of messages.
If you want to compare any 2 messages, simply select any 2 messages from the list, then right-click and select the “Compare Messages”.
Getting Statistics on an HL7 Field
One of the most powerful features of HL7Spy is calculating statistics on a particular field. In this example we are loading 100,000 messages and getting the statistics on PV1-2. You will notice that 50,178 with value “O”, and 14,733 with the value “E”.
You can navigate values of a particular type by using the forward and back buttons as shown in the short clip.
You can also right-click on a field type, say “O” and send all messages with PV1-2=”O” to a separate tab.
Load HL7 from zip, xz, 7z, gz
In the example above we are loading 300,000 files from xz, zip, and gzip files. HL7Spy takes care of detecting the file type, decompressing, and loading the files.
Load Messages with FTPS/SFTP
Message can be loaded directly from an FTP server using secure FTPS, or SFTP.
Load Messages From Database
Messages can be loaded from Sql Server, Oracle, Postgres, My Sql and many other databases. HL7Spy will automatically detect which column contains the message data and will load the messages into the message editor. Clicking on a row in the result set will display the associated message in the Message Editor.
Load Messages From Folder
Directories can be loaded recursively and filtering by file extension and file content are also supported.
Load 100K Messages From a File
In this example we are loading 100,000 messages using the “Open File” menu option, then we are opening another 100,000+ messages by dragging and dropping them using Windows File Explorer.

How can I remove RXA-12, not just delete the value, but remove it?
Question: How can I remove RXA-12, not just delete the value, but remove it so that RXA-13 becomes the new RXA-12?
To do this you can use the simple function below. They way it works is to go through all RXA segments and calls the RemoveAt(12) on the segment fields. This will remove the field causing all fields after RXA-12 to be offset by one.
public override void Run()
{
HL7Message message = GetParsedMessage();
foreach(HL7Segment segment in message.GetSegments("RXA"))
{
segment.Fields.RemoveAt(12);
}
this.SaveMessage(message,"RXA-12 Removed");
}

Find Last A08/Visit not discharged A03
Question: How do I find the last A08/Visit not discharged.
This code searches through a message set, pulling the last A08 per visit/encounter. If the visit gets an A03 discharge message, then the visit is excluded from the final data set.
The final data set loads in a new tab and has only the last A08 for non-discharged encounters. If you want to include the A04s, see below for lines to comment out.
Note: that some of the A08 messages could still be for discharged patients. The PV1-45 discharge date/time may contain a value, but the original message set not have contained a corresponding A03.
Thank you to Scott Hall for contributing this code.

HL7Spy 3.0 Released!
Inner Harbour Software is please to announce HL7Spy 3.0, its latest release of its flagship product. HL7Spy 3.0 comes with a completely new user interface that makes HL7Spy more efficient and easier to use. HL7Spy 3.0 also comes packed with new features, enhancements, and performance improvements. A sampling of these can be found below.
New User Interface
The new user interface provides for a much richer user experience. The new Ribbon Bar makes navigating HL7Spy’s functionality faster and easier. The tool buttons are larger and include text identifies the functionality being provided. Context sensitive help appears when hovering over a button. These new UI will make using HL7Spy more efficient for both beginners and existing HL7Spy pros alike.
Additional User Interface Enhancements
- Ribbon Bar can be shown/hidden with Cntr-F1 allowing the user to maximize message display area
- HL7Spy skin, back shadowing, and Aero Glass can be changed allowing the user to optimize the look and feel of the UI
- Short-cuts can be added to the application title bar for quick access to frequently used tools
- The Ribbon tabs, menus, and buttons can be access via the keyboard using the Alt key followed by the short-code displayed after the Alt key is pressed.
NEW HL7 Timeline Tool
The new HL7 Timeline Tool provides an over-view of the message volume over time for the currently displayed tab. This tool is useful when you are navigating a very large message stream and you want to see the messaging rate over time, or you want to quickly navigate to a particular date/time. In the example below, the message stream contains 100,000 messages. Note the spike in message throughput just before midnight every day.
HL7 Timeline Tool Features
- Can handle hundreds of thousands of messages
- Clicking on the timeline navigates the editor to that date/time
- Zoom In/Out using Shift-Click operations with the mouse
- Right-Click to export graph to png image file
- Right-Click to export raw data to Excel
New HL7 Transform Tool
The new HL7 Transform Tool allows users to make bulk modifications to messages within the current tab. While message transformation functionality has been available in HL7Spy since version 1.x, it has required users to write c# code snippets in the Custom Code tool. Now non-programmers can make bulk transformations to HL7 messages without having to write code.
HL7 Transform Tool Features
- Set fields to constant values. Eg, MSH-4=’FIXEDVALUE’ – sets MSH-4 to FIXEDVALUE
- Copy fields from one part of the message to another. Eg, MSH-5=MSH-4 – sets MSH-5 to the value in MSH-4
- Use a table to map one field to another. Eg PV1-2 = Table(PV1-2,’ER’ -> ‘E’, ‘OP’ -> ‘O’, ‘IP’ -> ‘I’) – maps ER to E, OP to O, and IP to I
- Use conditions to control when a transformation is triggered. Eg, MSH-4=MSH-4+’-INPATIENT’ when PV1-2=’I’ – appends ‘-INPATIENT’ to MSH-4 if PV1-2 is set to ‘I’
- Test button runs the transform on the message currently displayed in the editor to test the results of the transform
New Other HL7Spy 3.0 Features/Improvements
- Cloverleaf Smatdb files can now be opened with HL7Spy

How do I pull all OBX-5s where OBX-3.1=’SS003′
Question:
I am working on a syndromic surveillance feed for the CDC and hope you can help me with an HL7 SQL question. The messages contain multiple OBX lines. In those lines, I need to pull:
data in OBX-5
from the segment where OBX-3.1 = ‘SS003’
The order and number of OBX segments varies, so I can’t always specify a specific OBX segment.
Is there a way to do this in HL7 Spy? I’m including a set of OBX segments below as an example.
OBX|1|NM|11289-6^BODY TEMPERATURE:TEMP:ENCTRFIRST:PATIENT:QN^LN||97.4|degF^FARENHEIT^UCUM|||||F
OBX|2|NM|59408-5^OXYGEN SATURATION:MFR:PT:BLDA:QN:PULSE OXIMETRY^LN||97|%^PERCENT^UCUM|||||F
OBX|3|CWE|8661-1^CHIEF COMPLAINT:FIND:PT:PATIENT:NOM:REPORTED^LN||||||||F
OBX|4|CWE|8661-1^CHIEF COMPLAINT:FIND:PT:PATIENT:NOM:REPORTED^LN||||||||F
OBX|5|NM|21612-7^AGE TIME PATIENT REPORTED^LN||60|a^YEAR^UCUM|||||F
OBX|6|CWE|SS003^FACILITY / VISIT TYPE^PHINQUESTION||225XN1300X||||||F
OBX|7|TX|44833-2^DIAGNOSIS.PRELIMINARY:IMP:PT:PATIENT:NOM:^LN||per ems pt with increased confusion. pt also presents with ulcers to bilateral feet||||||F
OBX|8|AD|SS002^TREATING FACILITY LOCATION^PHINQUESTION||701 10TH STREET SE||||||F
Answer:
The best way to accomplish this is to write a small amount of Custom Code. In the example below, all OBX-5 values where OBX-3.1 = ‘SS003’ will be placed in a file called obx5s.csv. Once all the messages have been processed the file will automatically be opened in excel, if it is installed on the computer.
private StreamWriter _writer;
private string _fileName = Path.Combine(Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop),"ob5s.csv");
public override void OnStart()
{
_writer = new StreamWriter(_fileName,false);
}
// Called once or many times based on RunTypeRequested
public override void Run()
{
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
foreach(var obx in message.OBXs)
{
if(obx[3,1,1] == "SS003")
_writer.WriteLine("{0}", obx[5]);
}
}
public override void OnFinish()
{
if(_writer!=null)
{
_writer.Close();
_writer = null;
System.Diagnostics.Process.Start(_fileName);
}
}

How do I export fields from repeated segments?
Question:
I am trying to pull data from multiple HL7 messages using the SQL query: SELECT *, PID-5.1 as ‘B Last Name’, PID-5.2 as ‘B First Name’, OBR-4.1 as ‘Order Number’, OBR-4.2 as ‘Order’ WHERE MSH-11 != ‘T’
The issue I’m having is messages with multiple OBRs. How can I get data all the data from the SQL statement and the data from each OBR on each message?
Answer:
Unfortunately you cannot use the HL7 SQL tool for this. This tool returns at most 1 row per message. You would have to write some custom code to do this.
The code in the example below will create a file on the desktop called out.csv which will be a comma separated list of the fields
string _fileName = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop),"out.csv");
StreamWriter _fileWriter;
public override void OnStart()
{
_fileWriter = new StreamWriter(_fileName,false);
}
public override void Run()
{
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
// skip any test messages
if(message.MSH[10]=="T")
return;
PID pid = message.Segments.First<PID>();
if(pid == null)
return;
// Get the first PID segment
foreach(OBR obr in message.Segments.OfType<OBR>())
{
_fileWriter.Write(pid[5,1,1]);
_fileWriter.Write(", ");
_fileWriter.Write(pid[5,1,2]);
_fileWriter.Write(", ");
_fileWriter.Write(obr.Segment.Path.Repeat);
_fileWriter.Write(", ");
_fileWriter.Write(obr[2,1,1]);
_fileWriter.Write(", ");
_fileWriter.Write(obr[2,1,2]);
_fileWriter.WriteLine();
}
}
public override void OnFinish()
{
if(_fileWriter != null)
{
_fileWriter.Close(); // close the file
_fileWriter = null;
// launch notepad to display the file.
System.Diagnostics.Process.Start("Notepad",_fileName);
}
}
How do I copy the value in HL7 field OBX[1]-14.1 to HL7 field OBR[1]-7.1?
Question:
I have a file of hundreds of HL7 messages and would like to copy the value in HL7 field OBX[1]-14.1 to HL7 field OBR[1]-7.1. Basically, I want to overwrite the contents of field OBR-7 with the contents of field OBX-14 on every message.
Answer:
The following code will loop through all the OBR segments, and set OBR-17 to the value of the first OBX segment following the current OBR segment.
public override void Run()
{
HL7Message message = GetParsedMessage();
foreach(OBR obr in message.Segments.OfType<OBR>())
{
OBX obx = obr.Segment.GetRelative<OBX>(1); // get the next OBX
if(obx != null)
obr[17] = obx[14];
}
SaveMessage(message.ToString(), "Result");
}

How do I find all A14 messages that do not have a matching A05?
Question:
Thanks for making such a great product. 🙂 Question, I have two tabs open with ADT messages. I need to do a query to see what patients are in the first tab and are not in the second. There is not select Join type function supported. My first tab is A04’s and the second is A14’s. Need to know which A04’s don’t have my patient in the A14’s list.
I send a quick registration (A14) to a system that returns a A05 (or it should). I need to know when an A05 is not returned for an A14. The field I am actually matching on is PV1-50 (we put special IDs there).
Answer:
Thank you for being a supportive customer.
The only way I can think of doing this is to merge the two tabs into a single tab and write a Custom Code function to perform the analysis. See my solution below.
private string _fileName = @"C:\temp\results.txt";
private class TrackedItem
{
public int Index {get;set;}
public string AlternateVisitNumber {get;set;}
public string MessageControlId {get;set;}
}
Dictionary<string,TrackedItem> _a14s = new Dictionary<string,TrackedItem>(StringComparer.CurrentCultureIgnoreCase);
Dictionary<string,TrackedItem> _a05s = new Dictionary<string,TrackedItem>(StringComparer.CurrentCultureIgnoreCase);
public override void Run()
{
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
var pv1 = message.GetFirstSegment<PV1>();
if(pv1 == null)
return; // no PV1 segment
Dictionary<string,TrackedItem> collection=null;
if(message.TriggerEvent=="A14")
{
collection = _a14s;
} else if(message.TriggerEvent=="A05")
{
collection = _a05s;
}
if(collection == null)
return; // not an A05, or A04 message
TrackedItem item=null;
if(!collection.TryGetValue(pv1.AlternateVisitID_50.IDNumber_01.Value, out item))
{
// remember information about the message
item = new TrackedItem
{
Index = MessageIndex,
AlternateVisitNumber = pv1.AlternateVisitID_50.IDNumber_01.Value,
MessageControlId = message.MSH.MessageControlID_10.Value,
};
collection.Add(pv1.AlternateVisitID_50.IDNumber_01.Value, item);
}
}
// this is called at the very end
public override void OnFinish()
{
using(var stream = new System.IO.StreamWriter(_fileName))
{
stream.WriteLine("A14s without a matching A05");
ExportDiff(stream, _a14s, _a05s);
stream.WriteLine("A05s without a matching A14");
ExportDiff(stream, _a05s, _a14s);
}
try{
System.Diagnostics.Process.Start("Notepad",_fileName);
} catch{}
}
// show the difference between two collections
private void ExportDiff(StreamWriter writer, Dictionary<string,TrackedItem> collection1, Dictionary<string,TrackedItem> collection2)
{
foreach(TrackedItem item in collection1.Values.OrderBy(i=>i.Index))
{
if(!collection2.ContainsKey(item.AlternateVisitNumber))
{
writer.Write(item.Index.ToString());
writer.Write(" ");
writer.Write(item.AlternateVisitNumber);
writer.Write(" ");
writer.WriteLine(item.MessageControlId);
}
}
}

How to handle Z-Segments in Custom Code
Question:
How can we handle Z-Segments in HL7Spy’s Custom Code Tool?
Answer:
The following code demonstrates how use Z-Segments. We start by adding a couple of ZF1 segments (1), then we set a few fields (2), and finally print the fields out using the Log function.
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
// (1) Append a couple of ZF1 segments
message.Append(new Segment("ZF1")); // Append ZF1
message.Append(new Segment("ZF1")); // Append a second ZF1
string today=DateTime.Today.ToString("yyyyMMdd");
int count=0;
foreach(Segment zf1 in message.GetSegments("ZF1"))
{
++count;
//(2) set ZF1-3.1, and ZF1-3.2 with information from the MSH
zf1[3,1,1] = message.MSH[3,1,1] + "-V" + today;
zf1[3,1,2] = message.MSH[9,1,2] + "-TEST";
zf1[6] = count.ToString();
}
// (3) Log the information out using the Hl7Message class
string firstZF1_6 = message["ZF1-6"];
string secondZF1_6 = message["ZF1[2]-6"];
Log(Severity.Informational,string.Format("ZF1-6={0}", firstZF1_6));
Log(Severity.Informational,string.Format("ZF1[2]-6={0}",secondZF1_6));
// save the message out to a new tab
SaveMessage(message, "Modified Messages");
}

Find last known allergies for each patient
Question:
How can we use HL7Spy to find the last set of known allergies for each patient in a set of messages?
Answer:
The best way is to write a custom function that remembers the last set of allergies for each patient. Then in the OnFinished function we print out all patients with their last set of known allergies.
string _fileName = @"c:\temp\_test.txt";
Dictionary<string,Patient> _data = new Dictionary<string,Patient>(10000);
public class Patient
{
public Patient(string patientId)
{
Allergies = new HashSet<string>();
PatientId = patientId;
}
public HashSet<string> Allergies;
public string PatientId;
}
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
MSH msh = message.Segments.First<MSH>();
if(msh==null || msh.MessageType_09.TriggerEvent_02.Value!="A08")
return; // not an ADT^A08 message
PID pid = message.Segments.First<PID>();
if(pid==null)
return; // no pid segment
List<AL1> patientAllergies = message.Segments.OfType<AL1>();
if(patientAllergies.Count==0)
return; // no allergies
string patientId = pid.PatientIdentifierList_03.First.ToString();
Patient pat;
if(!_data.TryGetValue(patientId,out pat))
{
pat = new Patient(patientId);
_data.Add(patientId,pat);
}
pat.Allergies.Clear();
// loop through all AL1 segments
foreach(AL1 al1 in patientAllergies)
{
pat.Allergies.Add(al1.AllergenTypeCode_02.ToString());
}
}
// Called once after the last message has been processed.
// It is a good place to perform cleanup and to report information.
// Always called from the UI thread.
public override void OnFinish()
{
// to figure out the distribution of all allergies
Dictionary<string, int> allergies = new Dictionary<string,int>(1000);
// write the data out to a file
using(System.IO.StreamWriter wr = new System.IO.StreamWriter(_fileName))
{
wr.WriteLine("Patient ID vs Allergy for {0} patient samples",_data.Count);
wr.WriteLine();
foreach(Patient p in _data.Values.OrderByDescending(p=>p.Allergies.Count))
{
wr.Write(p.PatientId);
wr.Write(',');
wr.Write(p.Allergies.Count);
foreach(string s in p.Allergies)
{
wr.Write(',');
wr.Write(s);
// calculate the total number of allergy types for the given set of patients
int frequency=0;
if(!allergies.TryGetValue(s,out frequency))
{
allergies.Add(s,1);
} else {
allergies[s]=++frequency;
}
}
wr.WriteLine();
}
wr.WriteLine();
wr.WriteLine();
wr.WriteLine("Allergy distribution for {0} patient samples.",_data.Count);
wr.WriteLine("Number of distinct allergies is {0}.",allergies.Count);
wr.WriteLine();
foreach(KeyValuePair<string,int> d in allergies)
{
wr.Write(d.Key);
wr.Write(',');
wr.Write(d.Value);
wr.WriteLine();
}
}
// launch notepad to display the file.
System.Diagnostics.Process.Start("Notepad",_fileName);
}
Segments where OBX-15 differ from each other
Question:
Dear HL7Spy,
A user has a request – am not able to find function within HL7 to execute.
Find all the segments(i.e. OBX 15:1) within a message where content is different from each other. For example: If first OBX 15:1 is ABC, then find all other OBX within same message with content other than ABC.
Not sure if HL7Spy has that capability but thought I’d check.
Answer:
Sure, no problem, you can write a custom function to display all messages where this is true in a few lines of code.
To add this code, go to the Custom Code tool, select the “+” to add a new custom function, and cut and paste this code over-top of the default code that is displayed.
To run the code, load up a set of messages into a tab and click “Run”. What you should see is a new tab created that will contain any messages where the OBX-15 value differs between segments.
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
string obx15 = null;
foreach(OBX obx in message.Segments.OfType<OBX>())
{
if(obx15==null)
{
obx15 = obx.ProducerSID_15.Value;
}
else if(obx15 != obx.ProducerSID_15.Value)
{
SaveMessage(message,"Different OBX-15");
break;
}
}
}
Find the last ADT^A08 message for each patient in the message collection?
Question:
How can I find the last ADT^A08 message for every patient in a collection of messages?
Answer:
The best way to do this is to create a dictionary based on the patient Medical Record Number (PID-3). For each message receive. Look up the patient in the dictionary, if there is no entry, add one. Otherwise, replace the existing entry’s message with the new version. See the code below.
string _fileName = @"c:\_test.txt";
Dictionary<string,Patient> _data = new Dictionary<string,Patient>(10000);
public class Patient
{
public Patient(string patientId)
{
PatientId = patientId;
}
public IMessageData Message;
public string PatientId;
}
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
MSH msh = message.GetFirstSegment<MSH>();
if(msh==null || msh.MessageType_09.TriggerEvent_02.Value!="A08")
return; // not an ADT^A08 message
PID pid = message.GetFirstSegment<PID>();
if(pid==null)
return; // no pid segment
string patientId = pid.PatientIdentifierList_03.First.Value;
Patient pat;
if(!_data.TryGetValue(patientId,out pat))
{
pat = new Patient(patientId);
_data.Add(patientId,pat);
}
pat.Message = Message;
}
// Called once after the last message has been processed.
// It is a good place to perform cleanup and to report information.
// Always called from the UI thread.
public override void OnFinish()
{
SaveMessage(_data.Values.Select(p=>p.Message),"Last A08");
}
How do I remove PR1 segments?
Question:
Let’s say that I have a particular interface that is shipping me bad PR1 transactions, which is killing my interface. The vendor on the other side can’t make a change to his interface just yet, and I want to drop all those bad PR1s and let the vendor catch them up for me at a later date when he’s cleaned his data up. Is there a function that deals with including or deleting particular segments?
Answer:
If you create a new Custom Function and paste this code in, load up some messages with PR1 segments, and press “Run”, the PR1 segments will get stripped out.
public override void Run()
{
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
// remove any segment with name PR1"
message.RemoveAll(s=>s.SegmentName=="PR1");
// save the message into an new tab called No PR1s
SaveMessage(message, "NO PR1s");
}

Subset of messages for which there is more than one MRN per account number
Question:
How can we get the subset of messages for which there is more than one MRN associated with an account number?
Answer:
The best way to do this is to use a dictionary and track each message received based on the account number. At the end of processing all messages, check to see if any account has more than 1 MRN in its list. See the code below.
// Called once or many times based on RunTypeRequested
public class Tracker
{
private readonly List<string> m_medicalRecordNumbers = new List<string>(1);
public string AccountNumber {get;set;}
public List<string> MedicalRecordNumbers { get{return m_medicalRecordNumbers;} }
}
private readonly Dictionary<string,Tracker> m_items = new Dictionary<string,Tracker>(StringComparer.OrdinalIgnoreCase);
// Called once before the first message is processed.
// It is a good place to initialize objects.
// Always called from the UI thread.
public override void OnStart()
{
m_items.Clear();
}
public override void Run()
{
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
PID pid = message.GetFirstSegment<PID>();
if(pid==null)
return; // no pid segment
var accountNumber = pid.PatientAccountNumber_18.Value;
if(string.IsNullOrEmpty(accountNumber))
return; // no account number
var mrn = pid.PatientIdentifierList_03.First.Value;
Tracker tracker;
if(!m_items.TryGetValue(accountNumber, out tracker))
{
tracker = new Tracker{AccountNumber = accountNumber};
m_items.Add(accountNumber, tracker);
}
if(!tracker.MedicalRecordNumbers.Any(m=>string.Compare(m, mrn, true)==0))
tracker.MedicalRecordNumbers.Add(mrn);
}
// Called once after the last message has been processed.
// It is a good place to perform cleanup and to report information.
// Always called from the UI thread.
public override void OnFinish()
{
string path = Path.GetTempFileName();
using(var stream = new System.IO.StreamWriter(path))
{
List<Tracker> itemsWithMultipleMrns = m_items.Values.Where(i=>i.MedicalRecordNumbers.Count > 1).ToList();
if(itemsWithMultipleMrns.Count == 0)
{
stream.WriteLine("No Account numbers were found with duplicate MRNs");
} else
{
foreach(Tracker item in itemsWithMultipleMrns)
{
stream.Write(item.AccountNumber);
foreach(var mrn in item.MedicalRecordNumbers)
{
stream.Write(" ,");
stream.Write(mrn);
}
stream.WriteLine();
}
}
// show the results in notepad
try
{
System.Diagnostics.Process.Start("Notepad", path);
} catch(Exception ex)
{
this.Log(Severity.Error, string.Format("Could not open file '{0}' with notepad",path));
}
}
}

Capture EVN-1, PID-3, PV1-2, FT1-2 to file
Question:
How can I capture a list of the following fields: EVN-1, PID-3, PV1-2, FT1-2 in a comma delimited list?
Answer:
Custom code is the best approach if you are expecting repeated FT1 segments. The following code will create a file in the c:\temp directory containing the specified list, and will display in Notepad upon completion.
string _fileName = @"c:\temp\_test.txt";

Messages with duplicate OBR-3.1 to a new tab
Question:
I’m looking the way to get “DISTINCT” OBR-3.1 value messages. How can I do this in custom code. I want to show any messages that have duplicate OBR-3.1 values to a new tab. Please note we have multiple OBR segments per message.
Answer:
The following code should do the trick.
private class TrackedItem
{
public List<IMessageData> Messages=new List<IMessageData>();
public int Index {get;set;}
}
Dictionary<string,TrackedItem> _knownValues = new Dictionary<string,TrackedItem>(StringComparer.CurrentCultureIgnoreCase);
public override void OnStart() {
_knownValues.Clear();
}
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
OBR obr = message.Segments.First<OBR>();
if(obr != null && !string.IsNullOrEmpty(obr.FillerOrderNumber_03.Value))
{
string obrIdentifier = obr.FillerOrderNumber_03.Value;
TrackedItem item;
if(!_knownValues.TryGetValue(obrIdentifier,out item))
{
item = new TrackedItem();
_knownValues.Add(obrIdentifier,item);
} else
{
Log(Severity.Informational,string.Format("duplicates found at index",MessageIndex));
if(item.Index==0)
item.Index = MessageIndex;
}
item.Messages.Add(Message);
}
}
public override void OnFinish() {
var list = _knownValues.Values.Where(i=>i.Messages.Count>1).ToList();
Log(Severity.Informational,string.Format("{0} duplicates found",list.Count));
foreach(TrackedItem item in list)
{
SaveMessage(item.Messages,"Duplicates");
}
}
How do I create test data from a set of messages?
Question:
I would like to book some of you and or your teams time to develop or enhance HL7spy custom codes or product for my team. We would like the custom code to do the following:
- Take HL7 transactions (loaded in the Query Results tab)
- Append “-” + OBR-2.1 … to OBR-3.1 + “-” + some variable, ‘date yyyymmdd’
- Append “-” + some variable like “TEST” to OBR-3.2
- Delete the contents of OBR-2
Answer:
No need to hire us. This is pretty easy to do. There are two ways of accomplishing this: using type safe classes, and using field position specifications. Type safe classes provide the benefit of automatically documenting the code.
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
string today=DateTime.Today.ToString("yyyyMMdd");
// loop through all the OBR segments in the message
foreach(OBR obr in message.GetSegments<OBR>())
{
//(2) Append "-" + OBR-2.1 ... to OBR-3.1 + "-" + some variable, 'date yyyymmdd'
obr.FillerOrderNumber_03.EntityIdentifier_01.Value = obr.PlacerOrderNumber_02.EntityIdentifier_01.Value + "-V" + today;
//(3) Append "-" + some variable like "TEST" to OBR-3.2
obr.FillerOrderNumber_03.NamespaceID_02.Value = obr.FillerOrderNumber_03.NamespaceID_02.Value + "-TEST";
//(4) Delete the contents of OBR-2
obr.PlacerOrderNumber_02.Value = "";
// save the message out to a new tab
SaveMessage(message, "Modified Messages");
}
}
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
string today=DateTime.Today.ToString("yyyyMMdd");
foreach(OBR obr in message.GetSegments<OBR>())
{
//(2) Append "-" + OBR-2.1 ... to OBR-3.1 + "-" + some variable, 'date yyyymmdd'
obr[3,1,1] = obr[2,1,1] + "-V" + today;
//(3) Append "-" + some variable like "TEST" to OBR-3.2
obr[3,1,2] = obr[3,1,2] + "-TEST";
//(4) Delete the contents of OBR-2
obr[2] = "";
// save the message out to a new tab
SaveMessage(message, "Modified Messages");
}
}
Find all unique OBX-3/OBR-3 values
Question:
Hi, I am using HL7Spy HL7 SQL for the first time and am trying to pull the values stored in obx-3.1.1 for repeating obx segments but it seems to be only pulling the first value. I thought that this query would accomplish what I needed but I do not believe it is.
SELECT OBx[*]-3.1.1,OBx[*]-3.2.1 WHERE OBx[*]-3.1.1 IS NOT NULL
I would also like to find all unique OBR-4 values too.
Answer:
The HL7 SQL function will only return one result per message, so it probably not what you are looking for.
It would be quite easy to write a Custom Function to do what you are looking for. Is your goal to get a list of OBX-3.1, OBX-3.2 pairs with perhaps a count of how many times each pair occurred? If so, here is some code that will do just that.
private class TrackedItem
{
public string Key {get; set;}
public string Value {get;set;}
public int Counter {get;set;}
}
Dictionary<string,TrackedItem> _knownValues = new Dictionary<string,TrackedItem>(StringComparer.CurrentCultureIgnoreCase);
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
foreach(OBX obx in message.Segments.OfType<OBX>())
{
string key = obx.ObservationIdentifier_03.Identifier_01.Value;
TrackedItem item;
if(!_knownValues.TryGetValue(key,out item))
{
item = new TrackedItem {Key=key, Value=obx.ObservationIdentifier_03.Text_02.Value};
_knownValues.Add(key,item);
}
item.Counter = item.Counter + 1;
}
}
private string _fileName = @"C:\temp\_test.txt";
public override void OnFinish() {
using(var stream = new System.IO.StreamWriter(_fileName))
{
stream.WriteLine("OBX-3.1, OBX-3.2, Count");
foreach(TrackedItem item in _knownValues.Values.OrderByDescending(i=>i.Counter))
{
stream.Write(item.Key);
stream.Write("\t");
stream.Write(item.Value);
stream.Write("\t");
stream.WriteLine(item.Counter.ToString());
}
}
try{
System.Diagnostics.Process.Start("Notepad",_fileName);
} catch{}
}
And, a variation on the same theme for OBR-4
private class TrackedItem
{
public string Key {get; set;}
public string Value {get;set;}
public int Counter {get;set;}
}
Dictionary<string,TrackedItem> _knownValues = new Dictionary<string,TrackedItem>(StringComparer.CurrentCultureIgnoreCase);
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
foreach(OBR obr in message.Segments.OfType<OBR>())
{
string key = obr.universalServiceIdentifier_04.Identifier_01.Value;
TrackedItem item;
if(!_knownValues.TryGetValue(key,out item))
{
item = new TrackedItem {Key=key, Value=obr.UniversalServiceIdentifier_04.Text_02.Value};
_knownValues.Add(key,item);
}
item.Counter = item.Counter + 1;
}
}
private string _fileName = @"C:\temp\_test.txt";
public override void OnFinish() {
using(var stream = new System.IO.StreamWriter(_fileName))
{
stream.WriteLine("OBR-4.1, OBR-4.2, Count");
foreach(TrackedItem item in _knownValues.Values.OrderByDescending(i=>i.Counter))
{
stream.Write(item.Key);
stream.Write("\t");
stream.Write(item.Value);
stream.Write("\t");
stream.WriteLine(item.Counter.ToString());
}
}
try{
System.Diagnostics.Process.Start("Notepad",_fileName);
} catch{}
}

Find all Unique OBR-4 – OBX-3 pairs in a message stream
Question:
Here is some custom code that you wrote for as a while back. The code exports a row for every unique OBR 4 and OBX 3 pair, and a count of the occurrences. This report is used by our lab mappers during the mapping process for a new laboratory. The lab mappers are requesting that the report contain additional information. Below is what they are requesting, with the more important item on top:
Include a full message with each OBR 4 – OBX 3 pair. It could be the 1st message for this pair, the last message for this pair, or any other message for this pair. Which message isn’t as import as actually having a message that contains the OBR 4 – OBX 3 pair. They plan to visually review this message as they are doing the mapping to resolve any issues with method, units, reference range, etc.
Include a list of OBR 4 terms only without any OBX information. They plan to use this for mapping the OBR 4 term, which we do for radiology and text reports.
Answer:
The following code will create a
private class TrackedItem
{
public string Value {get;set;}
public int Counter {get;set;}
}
Dictionary<string,TrackedItem> _knownValues = new Dictionary<string,TrackedItem>(StringComparer.CurrentCultureIgnoreCase);
private string _fileName = @"C:\temp\data.hl7";
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
foreach(OBX obx in message.GetSegments<OBX>())
{
string obrIdentifier = message["OBR-4.1.1"];
string obxIdentifier = obx.ObservationIdentifier_03.Identifier_01.Value;
string key = (obrIdentifier + "-" + obxIdentifier).Trim();
TrackedItem item;
if(key=="-")
continue;
if(!_knownValues.TryGetValue(key,out item))
{
item = new TrackedItem();
item.Value = string.Format("{0}|{1}|{2}|{3}|{4}|{5}|{6}|{7}",message["OBR-4.1"],message["OBR-4.2"],message["OBR-4.3"],obx.ObservationIdentifier_03.Identifier_01, obx.ObservationIdentifier_03.Text_02, obx.ObservationIdentifier_03.NameOfCodingSystem_03,obx.Units_06,obx.ReferencesRange_07);
_knownValues.Add(key,item);
}
item.Counter = item.Counter + 1;
}
}
public override void OnFinish() {
using(var stream = new System.IO.StreamWriter(_fileName))
{
foreach(TrackedItem item in _knownValues.Values.OrderByDescending(i=>i.Counter))
{
stream.Write(item.Counter.ToString());
stream.Write("|");
stream.WriteLine(item.Value);
}
}
try{

Find all CPT codes for each patient
Question:
What I want to do is for each of the three accounts contained in PID-18, show all PR1-3 fields for all PR1 segments. Typically, these are sequential segments, e.g., PR1|1…, PR1|2…, etc. The purpose is to generate a list of all procedure and CPT codes for each of the patients.
Answer:
please try the following code:
make sure you can access the c:\temp directory, that is where the file is being stored.
To narrow the search, use HL7 SQL to filter for the patient accounts you are interested in, into a separate tab (SELECT INTO).
or, modify the _patientAccount list below to include the patients you want included, and uncomment the code with the // (1) “Uncomment me” comment
string _fileName = @"c:\temp\_test.txt";
private StreamWriter _writer;
// patient Identifiers
private string[] _patientAccounts = new string[]{"952-11-3088", "H000759100", "H000759092", "H000759118"};
public override void OnStart() {
_writer = new StreamWriter(_fileName);
}
public override void Run() {
// Get an HL7 Message in parsed format
HL7Message message = GetParsedMessage();
PID pid = message.Segments.First<PID>();
if(pid==null)
return; // no pid segment
// (1) Uncomment me
//if(!_patientAccounts.Contains(pid[18,1,1]))
// return;
foreach(var pr1 in message.Segments.OfType<PR1>())
{
if(pr1[3]!="")
{
_writer.WriteLine("{0},{1},{2},{3},{4},{5}",this.MessageIndex, pid[18], message.MSH[7], message.MSH[10], pid[5], pr1[3]);
}
}
}
// Called once after the last message has been processed.
// It is a good place to perform cleanup and to report information.
// Always called from the UI thread.
public override void OnFinish()
{
if(_writer!=null)
{
_writer.Close();
_writer = null;
}
// launch notepad to display the file.
System.Diagnostics.Process.Start("Notepad",_fileName);
}
