INFECTION CONTROL IN ISOLATION UNITS/HDUS/ICUS- A COMPARATIVE STUDY USING THREE DIFFERENT DISINFECTANTS WITH FOGGER FOR ENVIRONMENTAL DECONTAMINATION
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 38
Abstract
BACKGROUND Intensive care units (ICUS), High dependency units (HDUS) and Isolation units or wards carry high risk of nosocomial infection, morbidity, mortality and health care cost. To limit the nosocomial infection, health care providers should adopt aggressive and effective infection control measures. The importance of disinfection is frequently acknowledged but previous data indicated little distinction between manual and automated area decontamination. WHO has updated guidelines on infection control from time to time. MATERIALS AND METHODS Various studies recommended automated fogging system for environmental decontamination and with this perspective we conducted our study using fogger with three different disinfectants namely 1) H2O2 silver solution; 2) Octyldecyldimethylammonium chloride, Dioctyldimethylammonium chloride, Didecyldimethylammonium chloride, Alkyldimethylbenzylammonium chloride; 3) N-Alkyldimethylbenzylammonium chloride, Didecyldimethylammonium chloride, Polymeric biguanide hydrochloride. During the study, rooms of isolation wards, high definition units and intensive care units were fogged separately with all the three disinfectants along with high end cleaning of all the surfaces. The swab samples were taken from various sites like wall, bed, floor and air. RESULTS The results of growth then obtained were compared and analysed. The causes of bacterial and fungal growth even after fogging were analysed and enumerated. The control measures were adopted to reduce bacterial and fungal growth to nil. CONCLUSION Infection control policy and guidelines were prepared and distributed to concerned departments for implementation and to check cross infection at various vulnerable points.
