Adverse Event Reporting: What the 48-Hour, 10-Day and 30-Day Deadlines Each Cover

1. Key takeaways

The claim that “death or serious injury must be reported within 48 hours” is wrong. Clause 5.7 of the Therapeutic Goods (Medical Devices) Regulations 2002 sets three tiers of deadlines: a serious threat to public health → 48 hours; an event that led to death or serious deterioration in health → 10 days; an event that could have led to death or serious deterioration (a near adverse event) → 30 days. The clock starts on the day the sponsor becomes aware of the event — not on the date the event itself occurred. The three tiers are tied to the severity profile of the event, so the sponsor must classify first and then report within the matching window; an error made at triage becomes a breach even if the report itself was prepared quickly. The obligation is therefore two-step: classify against clause 5.7, then file inside the window the classification selects.

2. Legal basis

The reporting regime rests on the provisions below. The three deadlines in clause 5.7 are cumulative tiers, and each tier is paired with its own investigation and follow-up duties under the same Division. The clause numbers below refer to the compiled version of the Regulations, and the reporting duties they create are anchored in the Act through section 41FN(3)(d).

1. Therapeutic Goods (Medical Devices) Regulations 2002 (F2002B00237, compiled version F2026C00883): the reporting deadlines appear in clause 5.7 — (i) a serious threat to public health: 48 hours; (ii) an event that led to the death of a patient, device user or other person, or to a serious deterioration in their state of health: 10 days; (iii) an event that could have led to death or serious deterioration (a near adverse event): 30 days.
2. Investigation report: clause 5.8A — after a report is made within the applicable deadline, a written investigation report must be submitted within 120 calendar days; for similar events, information covering the previous 3 years must be provided.
3. Three-stage reporting: initial, follow-up and final; the final report must be submitted within 120 calendar days of the initial report.
4. Reporting route: sponsors are required to use the Medical Device Incident Reporting system (MDIR, accessed with a TGA eBS username and password), and reports enter the IRIS database; the support mailbox is IRIS@health.gov.au (TGA, Obligations to report an adverse event for medical devices, 6 February 2026).
5. Overarching obligation: section 41FN(3)(d) of the Therapeutic Goods Act 1989.
6. Consequences of failure: reporting outside the applicable deadline constitutes a breach of the conditions of inclusion and can lead to suspension or cancellation of the ARTG entry; in certain circumstances it also constitutes a criminal offence or a civil offence.

3. Expert insights

Insight 1: the 48-hour tier is the one most often misapplied. It applies to a serious threat to public health — a population-level risk — and not to a single death. A single death follows the 10-day track. Swapping these two numbers is the most common error found in Chinese-language materials, and it matters in both directions: treating every death as a 48-hour case exhausts response capacity, while treating a genuine public-health threat as a 10-day case puts the sponsor in breach of the shortest deadline in the regime. The distinction is not academic: the 48-hour window is reserved for events that signal a broader risk to the public, and its brevity is precisely what makes upstream detection mechanisms necessary. Classification should therefore be a documented decision, made against the clause wording, before any reporting clock is started.

Insight 2: there is another 120-day deadline that is easily left out. After the initial report there is a separate final report obligation, which must be submitted within 120 calendar days and must include information on similar events over the previous 3 years. Filing only the initial report without the final report is likewise incomplete performance of the duty. The final report is where the investigation record is consolidated; leaving it undone leaves the initial report as the only account of the event in the TGA’s hands.

Insight 3: the clock starts on awareness, which demands an awareness-triggers-reporting mechanism. If adverse events are aggregated monthly before any assessment takes place, the usable time within the 10-day and 30-day windows is in practice compressed. In client systems we therefore move the reporting trigger upstream to the customer service and sales functions, and record who became aware, how, and when, so that the start of the clock can be evidenced if the timeline is later questioned.

4. Practical recommendations

• Establish three response tiers — 48 hours (serious threat to public health), 10 days (death or serious deterioration), 30 days (near adverse events) — and assign a separate escalation contact for each tier, and rehearse the tiers periodically so that the classification decision can be made within hours rather than days.
• Move the reporting trigger upstream to customer service, sales and clinical application teams, and record the awareness date as a dedicated system field, entered with a timestamp rather than a date-only value.
• Start a 120 calendar day countdown for the final report as soon as the initial report is submitted, and prepare a search for similar events over the previous 3 years.
• Complete MDIR account configuration and permission assignment in advance, so that the first report is not delayed by account problems — account creation, user roles and login credentials should be tested before any live incident occurs.

5. Verification checklist

• □ Response tiers have been configured correctly for the three scenarios (48 hours / 10 days / 30 days)
• □ The awareness date has been set up as a recorded system field
• □ The 120 calendar day countdown for the final report has been set up
• □ A mechanism for retrieving similar events over the previous 3 years is in place
• □ MDIR accounts and permissions have been fully configured
