Vigilance Reporting Timelines for Medical Devices in Tanzania

1. Key takeaways

Tanzania sets vigilance reporting timelines in three tiers by severity of outcome. The statutory basis is Regulations 41–44 of GN 315, restated in the schedule to the Regulations (the reporting timelines table) as a three-row list:

The wording of Regulation 42(1) itself is:

• Regulation 42(1)(a)(i): an in-country incident that has led to death or a serious deterioration in health — the initial report must be submitted within 24 hours of the registrant, manufacturer or importer becoming aware of the incident;
• Regulation 42(1)(a)(ii): an in-country incident that has not led to death or a serious deterioration in health, but might do so if it were to occur — within 14 days of becoming aware;
• Regulation 42(1)(b): an incident occurring outside Mainland Tanzania — submitted as soon as possible.

3. Expert insights

Insight one: there are four categories of reporting duty holders, and the duty covers incidents occurring abroad for devices sold in Tanzania.

Regulation 41 provides that every registrant, manufacturer, importer and distributor must submit an initial report and a final report on any incident that comes to their attention — whether the incident occurs within or outside Tanzania — involving a device sold in Mainland Tanzania, where two conditions are met: the incident is related to any failure of the device, a deterioration in its effectiveness, or any inadequacy in its labelling or instructions for use; and it has led to the death of, or a serious deterioration in the health of, any patient, user or other person.

The occurrence outside Tanzania clause is critical: an incident at a Chinese manufacturing plant involving a product already exported to Tanzania falls within the reporting scope.

Insight two: the three-tier timelines differ slightly between the provision and the schedule, and the stricter reading should govern.

Regulation 42(1)(a)(i) ties 24 hours to incidents that have led to death or a serious deterioration in health; the schedule’s timelines table ties 24 hours to a serious threat to public health and 14 days to death or serious injury. The two attachments do not align perfectly. The GRZAN practical estimate is to launch the 24-hour track whenever death, serious injury or a serious public health threat appears, and to use 14 days (potential cases) or 30 days (others) otherwise. Applying the strictest tier is the safest course.

Insight three: the TMDA website vigilance page states two tiers, not the three of the Regulations.

The TMDA website page Vigilance and Post Marketing Surveillance states: Serious events must be reported within 24 hours. Other events and incidents must be reported within 30 days. That is a two-tier statement. The Regulations themselves contain three tiers (including the 14-day tier). The Regulations govern, and the website page serves as an operational reminder.

Insight four: the content of the final report and the follow-up actions are statutory.

Regulation 44(1): after the initial report, a final report must be submitted in accordance with the timetable established under Regulation 43(2)(h). Regulation 44(2): the final report must contain a description of the incident, including the number of cases of serious deterioration in health or death; a detailed explanation of the cause of the incident and justification for the actions taken; and any action taken after investigation, which may include enhanced post-market surveillance of the device, corrective and preventive action (CAPA) on the design and manufacture of the device, or recall of the device.

Insight five: the information requirements of the initial report are specific and differ by reporter identity.

Regulation 42(2): the initial report must include the name and identification of the device (including identification as part of a system, test kit, group, family or family group). Where reported by a manufacturer, it must include the name and address of that manufacturer and of any known importer, and the name, title, telephone and fax of the manufacturer’s representative for the incident; where reported by an importer, the name and address of the importer and the manufacturer, and the corresponding details of the importer’s representative. A declaration must also be made whether the device has previously been reported to TMDA and, if so, the date of that report.

4. Practical recommendations

1. Run an incident register that starts the clock at the moment of awareness — the trigger is when the company becomes aware, not when the event occurred.
2. Launch the initial report within 24 hours for every death, serious injury or serious public health threat, not at 14 days.
3. Report foreign incidents too: Regulation 41 expressly covers incidents occurring outside Tanzania involving devices sold in the country.
4. Write the final report in the three-part structure of Regulation 44(2) (description with case numbers, cause and justification, follow-up actions), naming the three optional actions.
5. Maintain a 24-hour contact channel with the LRP — Regulation 9(a) requires the LRP to notify TMDA immediately upon finding problems.
6. Prepare reporter identity templates under Regulation 42(2), in manufacturer-reported and importer-reported versions.

5. Verification checklist

• □ A three-tier timeline register exists: 24 hours (death, serious deterioration, serious public health threat), 14 days (potential cases), 30 days (others).
• □ The clock starts at the moment of awareness.
• □ Incidents occurring outside Tanzania involving devices sold in the country are within the reporting scope (Regulation 41).
• □ The final report is prepared in the three-part structure of Regulation 44(2).
• □ The initial report is prepared under Regulation 42(2), in manufacturer and importer versions.
• □ A 24-hour contact channel with the LRP exists (Regulation 9(a)).
• □ The difference between the two-tier website wording and the three-tier Regulations is understood, with the Regulations applied and the stricter tier used.
