1. Why decontamination matters — GDC, CQC and HTM 01-05
Course overview
Disinfection and decontamination is a GDC highly recommended CPD topic. This course is 2 hours of verifiable CPD and maps to GDC Development Outcomes C and D.
Suggested study time
- Regulatory context — 15 min
- Chain of infection and standard precautions — 15 min
- Hand hygiene, PPE and dirty-to-clean workflow — 20 min
- Cleaning and washer-disinfectors — 20 min
- Sterilisation, wrapping and storage — 25 min
- Environment, waterlines, impressions, sharps and records — 20 min
- Knowledge check (MCQ) — 5 min
GDC Development Outcomes
- Outcome C (primary): maintenance and development of knowledge and skill — running a safe decontamination process is core clinical work.
- Outcome D: behaviours that maintain patient confidence and public trust — documented, consistent infection prevention is part of professional practice.
Why this topic is not optional
Reusable dental instruments contact mucosa, blood and saliva. If they are not cleaned and sterilised correctly, infection can pass between patients, or staff can be exposed. Failures are usually process failures: rushed manual cleaning, wet storage, mixed dirty and clean traffic, or records that do not match what actually happens.
Key UK reference points
- HTM 01-05 (England) — decontamination in primary care dental practices. Other UK nations have equivalent national guidance; use the document that applies to your practice.
- CQC (England) inspects whether you have an effective system, not just a policy folder.
- GDC Standards require you to put patients’ interests first and to work with colleagues in a way that supports safety.
- COSHH and health and safety law cover chemicals, steam, sharps and staff vaccination.
Essential vs best practice
Guidance describes a baseline you must meet and a higher standard many practices work towards (for example, centralised decontamination rooms and validated washer-disinfectors). Know which standard your practice claims, and do not skip steps that your own policy says you follow.
Key message: decontamination is a system — people, rooms, machines, chemicals and records — not a single wipe at the end of a patient.
