Introduction
Core changes in the standard revision
| Revision dimensions | 2009 version | 2019 version | Clinical significance |
|---|---|---|---|
| Term definition | Inconsistent definition of hand disinfectant | Unified with GB 27950 standard | Regular product access requirements |
| Facility configuration | Ordinary faucets | Add non-hand-touch faucets as mandatory requirements in areas such as laboratories | Reduce the risk of cross-infection |
| Monitoring requirements | Compliance rate calculation is not clear | New formula: Compliance rate = number of execution opportunities / number of opportunities that should be executed × 100% | Quantitative management indicators |
Analysis of key technical points
1. Grading management of hand hygiene
The standard divides hand hygiene into three levels: hand washing (basic cleaning) → hygienic hand disinfection (routine diagnosis and treatment) → surgical hand disinfection (surgical operation), corresponding to different microbial control requirements:
- The colony count after hygienic hand disinfection is ≤10CFU/cm²
- The colony count after surgical hand disinfection is ≤5CFU/cm²
2. Innovation of surgical hand disinfection
2019 version refinement class=instrument>Rinse-free hand disinfectant usage process (Appendix C), clarify:
- Fingertip soaking time ≥ 5 seconds
- Circular rub forearm to lower 1/3 of upper arm
- Full rubbing time 3-5 minutes
Implementation suggestions for key departments
Operating room configuration plan
According to Article 5.2.2 of the standard, it is recommended that:
- An independent wash basin is set up for every 2-4 operating rooms
- The number of faucets ≥ the number of operating rooms
- Equipped with Sterile cloths (one for each person)
Special requirements for ICU
In combination with WS/T 509 specification:
- When the bed distance is ≥ 1.2m, 1 set of hand hygiene facilities is set up for every 2 beds
- Each bed is equipped with quick-drying hand disinfectant
Monitoring and quality improvement
Monitoring frequency
High-risk departments (operating room, ICU, etc.) should:
- Monitor hand hygiene effectiveness every quarter
- Monthly compliance spot check (unannounced visit and observation are recommended)
