ANSI AAMI ST79-2017 (2020) PDF

Full title and description

ANSI/AAMI ST79:2017 — Comprehensive guide to steam sterilization and sterility assurance in health care facilities (with Amendments A1–A4, 2020). This AAMI recommended practice consolidates guidance on steam sterilization, cleaning, inspection, packaging, storage, monitoring, maintenance, personnel, and quality management for sterile processing in healthcare settings.

Abstract

ST79 is the authoritative, facility-level guide for steam sterilization and sterility assurance across hospitals, ambulatory surgery centers, physician offices, endoscopy suites, dental offices and other clinical settings where reusable medical devices are processed. The 2017 edition (with 2020 amendments) provides procedural guidance, facility and equipment recommendations, personnel qualifications, testing and monitoring practices, and recordkeeping to support patient safety and regulatory/accreditation readiness.

General information

• Publication date: Original 2017 (amendments published 2020; consolidated/reissued in AAMI catalog as ST79:2017 with 2020 amendments).
• Publisher: Association for the Advancement of Medical Instrumentation (AAMI).
• ICS / categories: 11.080 (Sterilization and disinfection); related to health care technology and medical equipment standards.

• Number of pages: 248 pages (AAMI product listing).

Scope

ST79 provides comprehensive, facility-level guidance for the entire steam sterilization pathway: design and functional criteria for sterile processing areas (decontamination, preparation, sterilization, sterile storage), receiving/transport, instrument cleaning and inspection, packaging, steam sterilization cycles and validation, sterilizer installation and routine maintenance, biological/chemical/physical process monitoring, personnel qualifications and training, documentation and traceability, and quality process improvement. The 2020 amendments add clarifications and practical requirements (for example, environmental/food-and-drink policy in processing areas, inspection of insulated instruments, sterilizer cleaning frequency, and sterilizer recordkeeping details).

Key topics and requirements

• Design and zoning of sterile processing departments: decontamination, preparation/packaging, sterilization, and sterile storage.
• Point-of-use handling, transport, and cleaning processes for reusable medical devices; recommended equipment and cleaning validation considerations.
• Steam sterilization practices, cycle selection, validation and routine control, plus physical, chemical and biological monitoring.
• Instrument inspection and functional testing (including guidance added on inspection of insulated instruments and newer inspection technologies).
• Sterilizer care, routine cleaning schedules and maintenance requirements (amendments clarified recommended cleaning frequency).
• Packaging, sterile storage, shelf-life considerations and transport of sterile products.
• Personnel qualifications, education, competency verification and documentation practices.
• Recordkeeping and traceability (including amendments addressing recording lot identifiers in sterilizer records).
• Infection prevention alignment and survey/readiness expectations (used by accrediting bodies such as The Joint Commission).

Typical use and users

Primary users are sterile processing professionals, infection prevention teams, perioperative managers, biomedical/clinical engineering staff, facility safety/quality officers, device manufacturers (for IFU alignment), and surveyors/accreditors. ST79 is used daily as a practical reference for SPD procedures, staff training, sterilizer operation and monitoring, policy development, and survey preparedness.

Related standards

Commonly referenced companion and international documents include ISO 17665 (moist heat sterilization requirements and validation), ISO 11139 (vocabulary for sterilization), ANSI/AAMI ST98 (cleaning validation of health care products), ANSI/AAMI ST91 (endoscope processing), plus other AAMI TIRs and ISO/IEC standards addressing packaging, indicators, and sterilizer design. These documents are often used together with ST79 for process validation and technical alignment.

FAQ

Q: What is this standard?

A: ANSI/AAMI ST79:2017 is a comprehensive AAMI recommended practice that provides facility-level guidance for steam sterilization and sterility assurance in health care facilities; the current published package includes four 2020 amendments.

Q: What does it cover?

A: It covers design and workflow of sterile processing areas, cleaning and inspection of reusable devices, packaging and loading, steam sterilization cycle selection and validation, physical/chemical/biological monitoring, sterilizer maintenance, personnel competency, recordkeeping and quality process improvement. Amendments provide clarifications on inspection, cleaning schedules, sterile processing area practices and recordkeeping.

Q: Who typically uses it?

A: Sterile processing departments, infection prevention and control teams, perioperative services, biomedical engineering, quality/safety staff, device manufacturers (for aligning IFUs) and surveyors from accrediting bodies.

Q: Is it current or superseded?

A: As of the current consolidated publication, ST79:2017 with the 2020 amendments is the active AAMI document (often listed with a 2022 reissue/statement of record). AAMI has indicated a formal revision process for ST79 is underway, so users should monitor AAMI announcements for a future revised edition. Facilities should continue to follow the 2017 edition plus 2020 amendments until a new edition is published.

Q: Is it part of a series?

A: ST79 is part of AAMI’s sterilization/processing suite of standards and guidance (including ST91 for endoscopes, ST98 for cleaning validation, ST108 for water quality, and various TIRs). It is intended to work alongside ISO sterilization standards and applicable regulatory guidance.

Q: What are the key keywords?

A: Steam sterilization, sterility assurance, sterile processing, sterilizer validation, biological indicators, decontamination, instrument inspection, packaging, sterile storage, AAMI.
