Prevalence of Bacterial Contamination on Smart Cell Phone vs. Non-smart Phone
An observational study of Health Care Workers, Including Physicians, Nurses, and Nursing Aids, run by Seoul National University Hospital at 3 sites in South Korea.
Trial summary
Using smartphone is increasing in hospital with various purpose and it has more extended surface than non-smart phone. Therefore investigators can consider the bacterial contamination rate of smartphone will be higher than that of non-smartphone. Read more about this study

About this study
Official title: Bacterial Contamination of Smart Phones of Health Care Workers
Using smartphone is increasing in hospital with various purpose and it has more extended surface than non-smart phone. Therefore investigators can consider the bacterial contamination rate of smartphone will be higher than that of non-smartphone.
Read the detailed description
Hospital-acquired infections(HAI) are causing grave concern in almost all the hospitals of the world and causing increased morbidity and mortalities.
The transmission of HAI occurs through hospital staff and inanimate hospital environment, equipment, and devices that the hospital staff use.Recently, cellphones (CP) were blamed to cause nosocomial infections.
The mobile phones are used routinely all day long but not cleaned properly, as health care workers' may do not wash their hands as often as they should. The aim of the present study was to evaluate the prevalence of bacterial contamination of mobile phones in ICU health care providers. and especially compare the contamination rate between smartphone and non-smartphone.
Using smartphone is increasing in hospital with various purpose and it has more extended surface than non-smart phone. therefore we can consider the bacterial contamination rate of smartphone will be higher than that of non-smartphone.
