Summary
Operating theatre staff showed very low adherence to hand hygiene protocols, increasing the risk of healthcare-associated infections (HCAIs). Improving hand hygiene is crucial to prevent patient harm and microbial transmission in hospitals.
Area of Science:
- Healthcare epidemiology
- Infection control
- Surgical safety
Background:
- Healthcare-associated infections (HCAIs) pose a significant public health risk.
- Microbial contamination in operating theatres (OTs) contributes to HCAIs.
- Hand hygiene is a proven method for reducing infection rates, but adherence among OT staff is not well-documented.
Purpose of the Study:
- To assess the adherence of operating theatre staff to hand hygiene guidelines.
- To identify the frequency of hand hygiene opportunities and applications in the OT.
- To explore factors influencing hand hygiene practices among healthcare professionals.
Main Methods:
- Covert direct observations of OT staff (anaesthesiologists, nurses, surgeons, students) were conducted over 60 hours across 28 operations.
- Hand hygiene opportunities (entering/leaving OT, before patient contact) and potential contamination events were recorded.
- Non-surgical glove use and qualitative data on hand hygiene incentives were also collected.
Main Results:
- Observed hand hygiene application rate was extremely low, averaging 0.14 instances per hour per staff member.
- Adherence to hand hygiene upon entering or leaving the OT was 2% and 8%, respectively.
- Frequent staff-patient-environment interactions and potential contamination events were noted.
Conclusions:
- Operating theatre staff exhibited exceptionally low adherence to hand hygiene guidelines.
- This low adherence presents a significant risk for microbial transmission to patients.
- Urgent interventions are needed to improve hand hygiene practices and mitigate patient harm from HCAIs.

01:23Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:19Handwashing II: Pre-procedure and Initial Procedure Steps
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...

01:18Handwashing I: Introduction and Types of Equipment
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.

01:22Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
