Abstract:
The proper implementation of hand hygiene at key moments during patient care is the most important means of preventing healthcare-associated infection. Although there are many programmes aimed at enhancing hand hygiene, the compliance of healthcare workers (HCWs) remains incredibly low. One limiting factor is the lack of standardized measures and reports of hand hygiene opportunities. Direct observational audits have reported the weaknesses in this field. We report here a radiofrequency identification-based real-time automated continuous recording system (MediHandTrace(®)) that permits the tracking of hand hygiene opportunities and the disinfection compliance of HCWs that we evaluated against video recordings as being accurate (99.02%), sensitive (95.65%) and specific (100%). The system can also provide information that is useful to understand HCW non-compliance and will allow the evaluation of future intervention studies.

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....
Handwashing III: During the Procedure and Post-Procedure Steps
Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
Handwashing II: Pre-procedure and Initial Procedure Steps
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...
Assessing Body Temperature - Temporal Artery
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...
