Introduction :
There is an increased environmental contamination rate of CRA and MDRA in wards from 24% to
37.5% in 2Q 2022 in LKB. In order to increase the staff awareness of infection control and reduce the
Hospital Acquired Infection rate, a “Six Nursing procedure program” which included shower bathing,
napkin round, wound dressing, enteral feeding, open suction and urine bag emptying was
implemented in all wards in LKB since July 2022.
Objectives :
To reduce the infection rate through enhanced basic infection control practice:
1. Hand hygiene
2. Enhanced infection control measures in six nursing procedures identified.
To reduce the working environment contamination of MDRO
Methodology :
