Evaluation and comparison of efficacy of the surface disinfectants used in a tertiary care hospital Abstract Disinfectants play an important role in the prevention of nosocomial infections. A variety of disinfectants with different mechanism of action are available in the market. Most of the hospitals do not have a proper policy for the selection of an appropriate disinfectant and so they rely on the manufacturers claim about the disinfectant which is not always reliable. Though several methods have been developed for disinfectant testing most of them are not feasible because of their complex procedures. Thus in our study we employed a simple quantitative suspension method for testing the efficiency of the disinfectants. Four disinfectants- Hospital ot (1, 6 Dihydroy, 2,5 Dioxyhexane, glutaraldehyde, benzalkonium chloride solution, alkyl urea derivative), Srivlon (chlorhexidine gluconate, cetrimide, isopropyl alcohol), Emplura (Sodium hypochlorite solution; 4% w/v) and NICE (sodium hypochlorite solution; 5%w/v) were tested against three most common nosocomial pathogens Pseudomonas aeruginosa, MRSA and Candida albicans. All the disinfectants tested in this study exhibited good activity against all the three pathogens. Comparative evaluation of the disinfectants concluded that Hospal-OT had the maximum activity and Srivlon had the lowest.
