Risk of Microbial Contamination of Laptop Keyboard in Clinical Areaof Dental Settings. An In Vitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 5
Abstract
INTRODUCTION:Laptops are widely used in healthcare for improved and effective care. Healthcare providers move back and forth, between computers and patients while delivering healthcare, as a part of the daily routine. Investigations have suggested that laptops may contribute to cross contamination and can serve as vehicles for infection transmission in clinical area. AIM:This study was conducted to evaluate the microbial contamination found on laptop keyboards in clinical settings of various departments of a dental school in Greater Noida. METHODOLOGY:The examination was carried out by self administered questionnaire regarding the disinfection practices by the consenting participants and the specimen were collected from laptops that were located in the clinical section of different departments. This study was carried out at two intervals during morning before the clinical hours and at afternoon when laptop is exposed during clinical hoursThe samples were collected from 27 laptops from dentists working in a dental college in Greater Noida. The samples were collected aseptically using sterile cotton swabs dipped in sterile saline by rotating the swabs on the keyboard surfaces of laptops, inoculated into phosphate buffered saline (PBS), vortexed for 1 minute in Fischer Vortex Genie 2 on highest setting & streaked immediately on 5% Trypticase Soya agar plates and were incubated at 37°C for 24 hours aerobically. The isolates were evaluated based on the colony count and gram staining.STATISTICALANALYSIS:Descriptive statistics was done for the colony forming units The intergroup comparison for the difference of mean scores between the different departments was done using One Way ANOVA.RESULTS:The Intra department analysis of laptops was done to see the significance between the CFU/ml for the morning and evening samples which came out to be significant. percentage change in CFU/ml was analyzed between the departments maximum percentage change was found in Endodontics (1877.77). CONCLUSION : Laptops used in clinical area are potential reservoir for bacteria. They might be a vector playing an important role in the transmission of potential pathogenic microorganisms.
