For every sterilization cycle, the facility must produce a traceability sheet that allows identification of the cycle, the instruments processed, the responsible operator, and the parameters reached. UNI/TR 11408:2011 defines the minimum elements: cycle number, date, time, process parameters (temperature, pressure, time), result, operator. Every sterilized package 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.
In Italy, sterilization traceability is a legal requirement for every healthcare and body-modification profession. The goal is to be able to reconstruct, at any time, an instrument's complete journey: from sterilization to its use on a specific patient or client. D.Lgs 81/2008 Title X (Art. 274) and the ISPESL Linee Guida 2010 require healthcare practices to maintain complete traceability of the reprocessing chain. UNI/TR 11408:2011 defines the minimum elements of the traceability sheet for reusable medical devices. The regional laws on tattoo, piercing, and permanent makeup (Lombardia L.R. 13/2021, Toscana L.R. 28/2004, Lazio L.R. 2/2021) require dated logs of every sterilization cycle and equipment maintenance records.
The traceability sheet is the central document of this system: it gathers every piece of information about a sterilization cycle in a searchable, archivable format. Without it, traceability does not exist — there is only scattered data.
UNI/TR 11408:2011 defines the minimum elements a traceability sheet must contain: cycle date and time, unique cycle number (generated by the autoclave or the recording system), autoclave identification (serial number or name), program used (e.g. 134°C / 18 min prion cycle), process parameters (temperature, pressure, time), cycle result (conform/non-conform), process indicators (Bowie-Dick or Helix, chemical indicators, biological indicators), list of instruments in the load, identification of the operator who ran the cycle, and signature or electronic release.
For each sterilized package: lot number, sterilization date, use-by date, and a Class 1 chemical indicator (UNI EN ISO 11140-1). Optionally: lot number of the packaging material, observations ("partial load", "cycle repeated after failure", etc.).
Dental practices: traceability must allow linking an instrument to the patient it was used on. This requires a system that connects the sterilization cycle (date, number), the instruments in the load, and the patient record. In the event of a health alert (e.g. a patient diagnosed with hepatitis), the practice must be able to identify every patient who came into contact with instruments from the same lot. Legge Gelli Art. 4 adds the obligation to make documentation available within 7 days of patient request.
Tattoo, piercing, and permanent makeup: regional laws require client records (name, date, informed consent) and equipment sterilization records. Instrument-client traceability is mandatory: the package is opened in front of the client and the instruments used in each session are documented. EU Reg. 2020/2081 (REACH) also requires traceability of ink lot numbers.
Podiatry: as a regulated healthcare profession (D.M. 666/1994), traceability follows the same standards as dental practices. The podiatry practice must be able to demonstrate complete traceability during an ASL inspection.
The ISPESL Linee Guida and UNI/TR 11408 require reprocessing records to be retained for 5–10 years, depending on regional directive. Regional tattoo and piercing laws sometimes specify shorter periods for equipment maintenance records alone, but recommended practice is to retain all traceability documentation for the longest applicable period.
For professional liability under the Legge Gelli (Law 24/2017), the limitation period is 10 years for the healthcare facility (contractual liability, Civil Code Art. 1218) and 5 years for the individual practitioner (extracontractual liability, Art. 2043) — documentation must cover both periods. The practical recommendation is to retain all records as long as possible — a digital register has no space limits.
A paper logbook meets the minimum requirements if it contains every required field and is retained properly. However, it does not allow searches, does not generate automatic backups, and does not verifiably link instruments to patients. Paper traceability depends on the operator's discipline — one missed entry invalidates the entire system.
A digital system like SecuSteri automatically generates the traceability sheet from the autoclave report, links the instruments in each load to the cycle, allows instant searches, and exports data for inspections or audits.
