For every sterilization cycle, the practice must produce a traceability sheet that allows identification of the cycle, the instruments processed, the responsible operator, and the parameters reached. NP EN ISO 17665-1:2010 and NP EN ISO 13485 define the minimum elements: cycle number, date, time, process parameters (temperature, pressure, holding time), result, operator. Every sterilized pouch must carry the lot number, sterilization date, use-by date, and chemical indicator. This guide describes what the sheet must contain and how to link it to the individual instrument and patient.
Portuguese regulations require a traceability record for every sterilization cycle in dental practices, under Portaria n.º 99/2024/1 and Decreto-Lei n.º 127/2014. The ERS dental-clinic inspection form (mod-133_02) explicitly verifies the existence of cycle traceability — the practice must have a written reprocessing protocol approved by the clinical director and accessible in the reprocessing area. Tattoo and piercing studios in Portugal operate under a regulatory void at national level — no specific legislation exists, but APPTBP self-regulation recommends professional traceability records as best practice. Podiatry clinics (Lei n.º 65/2014) and veterinary clinics maintain traceability under the professional duty of care.
The traceability sheet is the central document of this system: it gathers all the information of a sterilization cycle in a consultable, archivable format. This guide details the recommended fields. For full regulatory requirements, see the sterilization regulations guide.
Every traceability sheet, aligned with NP EN ISO 17665-1:2010 and NP EN ISO 13485, should include at minimum: the date and time of the cycle, autoclave identification (name or serial number), the cycle number or batch number, the cycle type (standard 134°C / 5.5 min or prion 134°C / 18 min), the recorded parameters (temperature, pressure, holding time), the cycle result (pass or fail), the identity of the operator who loaded and validated the cycle, and the list of instruments or pouches included in the load.
For dental practices, additional fields are recommended: the link to the patient record (which patient received which instruments), the daily Helix or Bowie-Dick test results, and the use-by date marked on each pouch. For details on use-by dates, see the use-by date guide.
Dental practices have the strictest traceability requirements in Portugal — the instrument-to-patient link is expected, particularly for surgical and endodontic procedures. Portaria 99/2024/1 requires a written reprocessing protocol approved by the clinical director. Tattoo artists and piercers operate under no specific legislation, but APPTBP self-regulation (around 1,200 registered professionals, CETA member) recommends per-cycle records and per-client documentation for at least 3 years. Podologists, recognized under Lei n.º 65/2014, are expected to maintain the patient-instrument-cycle link, particularly for invasive procedures such as nail surgery. For veterinary clinics, sterilization documentation falls under the professional duty of care arising from the OMV Code of Conduct.
Across all professions, the autoclave's USB stick or thermal printout alone does not constitute a complete traceability record. It contains cycle parameters but not the load contents or operator identification.
Portaria 99/2024/1 does not set a specific retention period for sterilization records. The general healthcare-record convention applies — 5 years is a prudent minimum, with 10 years or more common for surgical procedures. Tattoo and piercing studios, while not subject to a specific Portuguese regulation, typically follow APPTBP guidance: 24 months minimum for equipment records, 3 or more years for client records aligned with the informed-consent obligation. In case of litigation, traceability records serve as evidence — retaining them beyond the minimum is prudent.
On paper, the record is filled in by hand after each cycle: date, time, cycle number, instrument list, signature. The risks: forgetting to fill it in, illegible handwriting, lost binders, no quick search capability. With a digital register like SecuSteri, the traceability sheet is generated automatically from the imported autoclave report. The operator validates the cycle with their PIN code, the instruments in the load are linked to the cycle, and a QR label is printed for each pouch. The complete record is instantly accessible during an ERS or IGAS inspection.
