Capturing and Sharing Patient-Level Measure Reports via FHIR Using Da Vinci Risk Adjustment with HealthShare

Overview

Organizations that need to capture, store, and share patient-level quality or risk adjustment measure results via FHIR can do so by extending HealthShare SDA and enabling transformation to the FHIR MeasureReport resource.

This article describes how to configure HealthShare to support the Da Vinci Risk Adjustment (RA) Implementation Guide by enabling storage and FHIR-based exchange of MeasureReport resources for individual patients or members.

The outcome of this configuration is the ability to persist MeasureReport data in SDA and expose it via FHIR R4 in compliance with the Da Vinci RA profile.

 

Solution Summary

This solution introduces a custom SDA3 container to store MeasureReport data for each patient and configures HealthShare to transform that data into a FHIR R4 MeasureReport resource.

The deliverables include:

  • A custom SDA container and related supporting classes
  • A custom DTL to transform SDA to FHIR
  • Configuration updates to register and enable the transformation
  • A test patient to validate end-to-end functionality

Once completed, HealthShare will:

  • Store MeasureReport data per patient in SDA
  • Automatically use the custom container
  • Expose the MeasureReport through the FHIR R4 endpoint in ODS

Implementation Steps

1. Download, Import and Compile Custom Code

Download MeasureReportCode.xml from GitHubhttps://github.com/smckennaisc/hs-measurereports-example/

Import and compile the contents of MeasureReportCode.xml into HSCUSTOM namespace in the following HealthShare environments:

  • Registry
  • Edge Gateway
  • ODS/FHIR Gateway
  • Clinical Viewer

Note: Applies to HealthShare v2025.1

Included Components in file

i. Custom SDA Container

  • HS.Local.SDA3.ZContainer.cls

ii. Custom SDA3 MeasureReport Classes

  • HS.Local.SDA3.ZMeasureReport.cls
  • HS.Local.SDA3.ZMeasureReportGroup.cls
  • HS.Local.SDA3.ZMeasureReportExtension.cls
  • HS.Local.SDA3.Streamlet.ZMeasureReport.cls
  • HS.Local.SDA3.CodeTableDetail.ZMeasureReportCategory.cls
  • HS.Local.SDA3.CodeTableDetail.ZGroupCode.cls
  • HS.Local.SDA3.CodeTableDetail.ZccRemark.cls

iii. Custom DTL

  • HS.Local.FHIR.DTL.SDA3.vR4.MeasureReport.MeasureReport

2. Register the Custom SDA Container

 

In HSREGISTRY, add the following Configuration Registry entry:

\CustomSDA3Container = HS.Local.SDA3.ZContainer

This ensures that HealthShare uses the custom SDA container when processing SDA3 data.


3. Enable the SDA-to-FHIR Transformation

 

In HSODS, update the following global:

set ^HS.XF.Transform("SDA3","vR4", "HS.Local.SDA3.ZMeasureReport", "HS.Local.FHIR.DTL.SDA3.vR4.MeasureReport.MeasureReport") = 1 

This explicitly enables the transformation from the custom SDA3 MeasureReport container to the FHIR R4 MeasureReport resource.


4. Update XFTransform.xml

 

Locate XFTransform.xml in the instance directory:

/dev/fhir/gbl/
  • You may need to temporarily set the file to read/write.

Add the following XML node after the SDA4 and vR4 nodes and before HS.SDA3.Address (typically around line 7):

<Node> <Sub>HS.Local.SDA3.ZMeasureReport</Sub> <Node> <Sub>HS.Local.FHIR.DTL.SDA3.vR4.MeasureReport.MeasureReport</Sub> <Data>1</Data> </Node> </Node>

This step ensures the transformation is recognized during runtime.


Testing and Validation

 

Download and Load Test SDA Data


Validate via FHIR API

Using Postman or another API testing tool, issue the following requests:

Query by Patient and Profile

https://<your-host>/csp/healthshare/hsods/fhir/r4/MeasureReport ?patient=100000012 &_profile=http://hl7.org/fhir/us/davinci-ra/StructureDefinition/ra-measurereport 
  • Replace <your-host> with your HealthShare URL
  • Replace 100000012 with the patient’s MPIID

Query All MeasureReports

https://<your-host>/csp/healthshare/hsods/fhir/r4/MeasureReport 

Expected Result:

  • A single MeasureReport resource should be returned

Validate in Clinical Viewer (CV)

 

  • Look up the patient “Test MeasureReport” in HealthShare's Clinical Viewer
  • Confirm the SDA record includes the custom MeasureReport container

Outcome

After completing these steps, your HealthShare environment will be capable of:

  • Persisting patient-level MeasureReport data in SDA
  • Transforming SDA data into a FHIR R4 MeasureReport resource
  • Sharing MeasureReport resources via FHIR in alignment with the Da Vinci Risk Adjustment Implementation Guide

This enables standards-based risk adjustment reporting and interoperability with downstream analytics, payers, and regulatory systems

Flight Refund & Cancellation Rules

Flight refund and cancellation rules depend on the airline, fare type, and when you cancel. Refundable tickets allow partial or full refunds, while non-refundable tickets usually have high penalties or no refund. Cancelling earlier costs less, and refunds can take several days or weeks to process.

Refunds and cancellations are one of the most stressful parts of booking flights. Many travelers only learn the rules after something goes wrong. Plans change, emergencies come up, or schedules shift. Suddenly, a cheap ticket becomes an expensive mistake. The problem isn’t that airlines hide information. The real issue is that refund and cancellation rules are written in complicated language that most people skip or don’t fully understand.

This guide explains refund and cancellation rules simply, especially for travelers booking international flights from Pakistan. No legal wording. No airline jargon. Just clear explanations so you know exactly what happens when you cancel a flight, miss a flight, or request a refund. If you understand these rules before booking, you can save money, avoid panic, and make smarter travel decisions.

The Most Important Rule About Flight Tickets

 

Not all flight tickets are refundable.

This single fact explains most refund problems.

Airline tickets are priced based on flexibility:

  • More flexibility = higher price
  • Less flexibility = cheaper price

When travelers choose the cheapest fare, they usually give up refund rights without realizing it.

Refundable vs Non-Refundable Tickets

Refundable Tickets

Higher cost, lower risk.

Refundable tickets:

  • Allow cancellation with minimal penalties
  • May offer full or partial refunds
  • Are common in flexible, premium, or business fares

These tickets are best if:

  • Your plans are uncertain
  • You may need to cancel or reschedule
  • You are traveling for work or emergencies

They cost more upfront but protect you from bigger losses later.

Non-Refundable Tickets

Cheaper, but strict rules apply.

Non-refundable tickets:

  • Usually do not return the ticket price
  • May only refund airport taxes
  • Often allow date changes with heavy fees

Most economy and promotional fares fall into this category. They are fine if your travel plans are 100% confirmed.

How Airline Cancellation Charges Actually Work

The closer you cancel to departure, the more you lose.

Airlines apply cancellation penalties based on:

  • Fare type
  • Time of cancellation
  • Airline policy

General Cancellation Timeline

While rules vary, this pattern is common:

  • More than 72 hours before departure: Lower cancellation charges
  • 24–72 hours before departure: Higher penalties
  • Less than 24 hours or after departure: Usually no refund

Some tickets become completely non-refundable once check-in opens.

International Flight Cancellations: What Makes Them Different

International flights have stricter rules and higher penalties.

International tickets involve:

  • Higher base fares
  • Multiple airports and countries
  • Additional taxes and fees

Airlines like Emirates, Qatar Airways, and Turkish Airlines all apply different rules based on fare type.

Some international fares:

  • Allow no cancellation at all
  • Allow cancellation but with large deductions
  • Allow date changes but charge fare differences

Always read international fare rules carefully.

How Long Do Flight Refunds Take?

Refunds are never instant.

Refund timelines depend on:

  • Airline processing time
  • Payment method
  • Bank processing speed

Typical Refund Timelines

  • Credit or debit card: 7–14 working days
  • Bank transfer: 10–21 working days

Delays can happen due to:

  • Airline approval queues
  • Weekends and public holidays
  • Banking system delays

Refunds often feel slow, but this is normal.

Are Airport Taxes Refundable?

Yes, in many cases.

Even if your ticket is non-refundable:

  • Airport taxes may be refundable
  • Fuel surcharges may not be refundable
  • Service fees are usually deducted

Tax refunds are often small, but they are still worth requesting.

Date Change vs Cancellation: Which Is Smarter?

Date changes are usually cheaper than cancellations.

Date Change

  • Lower penalty than cancellation
  • Fare difference may apply
  • Keeps ticket value usable

Cancellation

  • Higher penalties
  • Partial or zero refund
  • Longer processing time

If your travel is delayed, changing the date is usually the better option.

What Happens If the Airline Cancels Your Flight?

Airline-initiated cancellations usually protect the passenger.

If the airline cancels your flight due to:

  • Operational issues
  • Schedule changes
  • Weather disruptions

You are usually entitled to:

  • Full refund
  • Free rebooking
  • Travel credit

Always ask for your options before accepting anything.

What Is a No-Show and Why It Matters

Missing your flight can cancel your entire ticket.

If you don’t show up:

  • You may lose the full ticket value
  • Return or onward flights may be canceled
  • Refund is usually not allowed

If you know you won’t travel, cancel in advance. Even a late cancellation is better than a no-show.

Why Cheap Tickets Have Strict Refund Rules

Cheap tickets help airlines manage demand.

Airlines use cheap fares to:

  • Fill seats early
  • Attract price-sensitive travelers
  • Reduce risk of empty seats

In exchange, they limit refunds and flexibility. This trade-off is intentional, not unfair.

Common Refund & Cancellation Mistakes Travelers Make  

 

Most losses are avoidable.

Avoid these mistakes:

  • Assuming all tickets are refundable
  • Skipping fare rules during booking
  • Waiting too long to cancel
  • Missing check-in deadlines
  • Not saving booking confirmation

One small oversight can cost a lot.

How to Check Refund & Cancellation Rules Before Booking

Always read fare conditions before paying.

Before confirming your booking, check:

  • Refund eligibility
  • Cancellation penalty
  • Date change fees
  • No-show policy

Trusted booking platforms show these details clearly before payment.

Travel Insurance: Does It Help?

Sometimes, but not always.

Travel insurance may help if:

  • You cancel due to medical emergencies
  • Flights are canceled due to covered reasons

Insurance usually does not cover:

  • Change of mind
  • Personal schedule issues
  • Cheap promotional fares

Read insurance terms carefully.

How to Book Smartly If Plans Are Uncertain

Flexibility matters more than price.

If your plans may change:

  • Choose flexible fares
  • Avoid ultra-cheap deals
  • Cancel early if needed
  • Keep all booking records

Paying slightly more upfront can save much more later.

Where to Compare Flights With Clear Fare Rules

Understanding refund rules is easier when booking through transparent platforms.

You can compare flights and review fare conditions here:

This helps travelers:

  • Compare flexibility across airlines
  • See cancellation rules upfront
  • Avoid surprises later

FAQs: Refund & Cancellation Rules Explained Simply

Can I get a full refund on my flight ticket?

Only if your ticket is refundable or the airline cancels the flight.

Are non-refundable tickets completely useless?

No. Taxes may be refundable, and date changes may still be allowed.

How late can I cancel my flight?

This depends on the airline, but earlier is always cheaper.

What happens if I miss my flight?

You are marked as a no-show and usually lose refund rights.

Do airlines charge service fees?

Yes. Service and handling fees often apply.

Final Thoughts

Refund and cancellation rules don’t have to be confusing or scary. Once you understand how fare types, timelines, and penalties work, you can make informed decisions and avoid unnecessary losses.

Always read fare rules before booking, act early when plans change, and don’t assume flexibility unless it’s clearly stated.

Small VS Code features that will boost your productivity

The official InterSystems VS Code extensions are packed with features that make developing with InterSystems products a breeze. Today I'd like to highlight some small but useful features that you may have missed.

Show All Class Members

You can view all members of the current class, including inherited members, with the click of a button. Just click on the class icon in the top-right corner of the editor window and a filterable list of all members will appear. Clicking on one will reveal it in an editor tab.

  

Show Plan

Using SQL in your ObjectScript code is a popular way to take advantage of InterSystems IRIS's powerful multi-model capabilities. However, writing performant SQL queries can be a challenge. That's why InterSystems added the ability to view the execution plan of SQL statements with one click right from your editor tab. Just click the Show Plan button above class queries and Embedded SQL statements and a webview displaying ther execution plan will appear beside your code.

 

Open InterSystems Document

A neat feature of VS Code is that it allows you to have multiple root folders open at once. It's also common to have many files in each folder, which makes navigating to a file using the explorer UI cumbersome at times. While VS Code has commands for quickly opening a file by name, that is usually different than the InterSystems name for the document (for example, the file path for User.Test.cls will often be /User/Test.cls). In response to this discrepancy, InterSystems added a command to open a file using the InterSystems name for it. After selecting a workspace folder, a file explorer picker is shown. Users can browse for the file to open using it, or enter the name directly in the text box and press Enter. The command accepts dots for package separators and the short form for %Library classes.

 

Open Error Location

When trying to identify the cause of an error, a good first step is go to the source. If you have the error location handy, VS Code has a command that will open the exact line for you, even if it's in a generated routine that isn't in your workspace folder. From the command palette, type Open Error Location... and run the command. A text box will appear that accepts a location in an INT routine in the form label+offset^routine. Submitting the form will open that location in an editor tab if the source code exists. A user can then use the View Other command to open the equivalent line in the higher level source file if applicable.

 

As always, feedback and issues reports can always be made on GitHub. Thanks for reading and happy coding!
