Health NZ EHR Migration

A legacy patient management system is being replaced by a new cloud EHR. You're the Test Manager. Navigate the governance, privacy, three-vendor complexity, and clinical safety risk to a successful go-live.

Test Manager Practice Exercise 04 5 scenario questions + model answer
Programme Brief

The Situation

Health NZ Whanganui is migrating from a 1998-era Patient Management System (PMS Legacy) to CloudMed EHR — a cloud-hosted Electronic Health Record system. You have been contracted as Test Manager. The programme is 14 weeks from go-live.

The Players

EHR Vendor
CloudMed

Supplies and hosts the software

System Integrator
TechInt NZ

Configures and integrates CloudMed with existing systems

Agency IT
Health NZ Whanganui

Manages network and legacy interfaces in-house

You
Contracted Test Manager

Independent quality governance across all vendors

Key Facts

  • 47,000 active patient records to migrate
  • Go-live in 14 weeks
  • Regulated under: Health Information Privacy Code 2020 (HIPC), NZ Health and Disability Commissioner Act, Health and Safety at Work Act (clinical safety obligations)
  • Three integration interfaces: PMS Legacy → CloudMed (patient records), Lab system → CloudMed (results), Pharmacy system → CloudMed (prescriptions)
  • Ministry of Health sign-off on clinical safety required before go-live
  • Known data quality issues: ~3,000 records with missing date-of-birth; ~800 with duplicate IRD numbers
Clinical risk: Errors in patient records — wrong DOB, duplicate entries, misrouted lab results — can cause clinical harm. This is not a standard software migration.

Question 1 of 5

You've just joined the programme. What is your first deliverable?

Question 2 of 5

The three integration interfaces have no documented test ownership. What do you do?

Question 3 of 5

Data quality issues: 3,000 records missing date-of-birth, 800 with duplicate IRD numbers. CloudMed says they'll "handle it in migration." What is your response?

Question 4 of 5

MoH requires a clinical safety sign-off. What document does the Test Manager produce as input to that sign-off?

Question 5 of 5

Three weeks from go-live, a HIGH severity defect is found: the lab results interface sends results to the wrong patient record when a patient has a hyphenated surname. CloudMed says it's TechInt's configuration. TechInt says it's CloudMed's API. How do you handle it?

Model Approach: Health NZ EHR Programme

Work through all five questions first, then reveal what strong Test Manager practice looks like on a clinical programme.

What makes clinical systems different

Test Strategy Elements Unique to Clinical Systems

  • Clinical risk classification: Every test scenario must be classified by clinical impact — patient safety (high), care coordination (medium), administrative (low). Test sequencing follows risk, not technical convenience.
  • Patient safety test scenarios: Define specific scenarios for misrouted results, duplicate records, missing allergies, incorrect DOBs. These are not edge cases — they are primary test objectives on a clinical programme.
  • HIPC obligations for test data: No real patient data in test environments without explicit governance approval. Synthetic data must reflect clinical reality — including edge cases like hyphenated surnames, te reo Māori names, and records with incomplete fields.
  • Vendor sign-off requirements: Each vendor signs off their component and their integration seams independently. The Test Manager's summary report aggregates all vendor sign-offs — it is not a substitute for them.

One-Page Release Recommendation for the Clinical Director

Structure it as follows:

  1. Executive summary (3 sentences): What was tested, overall quality status, and recommendation.
  2. Scope tested: List of systems, interfaces, and data migration components covered. Note any areas explicitly not tested and why.
  3. Outstanding risk items: Every open defect by severity. For each medium or high item: the clinical risk if it occurs post-go-live, and who has accepted that risk.
  4. Clinical safety attestation: Statement that clinical test scenarios were executed, including patient safety scenarios, misrouted results, and duplicate record scenarios — with results.
  5. Recommendation: Go / Conditional Go (with named conditions) / No-Go. A Conditional Go means "go-live is acceptable IF these specific items are resolved within 48 hours of go-live." State the conditions explicitly.

NZ-Specific: Data Breach Notification

Under the Health Information Privacy Code 2020 and the Privacy Act 2020, a health data breach is notifiable to the Office of the Privacy Commissioner within 72 hours of the organisation becoming aware of it. The Test Manager's test summary report is part of the evidence chain in any post-incident investigation — it demonstrates what was tested, what was known, and what risks were accepted. If your summary report is vague or missing, it will be read as evidence of inadequate quality governance. Write it as if a regulator will read it — because they might.

Key Principle

"Clinical safety is not a vendor obligation — it is a programme obligation. You own the evidence that the system was tested adequately."

CloudMed can certify their product is safe. TechInt can certify their configuration is correct. Neither of them owns the end-to-end patient journey across all three vendors and all three integration seams. That is your scope, and it is non-negotiable on a clinical programme.
