Application of adenosine triphosphate bioluminescence assay in rapid detection of bacteria on the surface of health care workers’mobile phones / 中国感染控制杂志

ABSTRACT

Objective To detect bacterial content on surface of mobile phones of health care workers (HCWs)by adenosine triphosphate (ATP )bioluminescence assay.Methods HCWs in departments of internal medicine,surgery, medical laboratory,and administration were randomly selected,50 in each department,field detection on bacterial content on surface of mobile phones of HCWs was conducted,the relevant data were recorded.Results A total of 200 mobile phones were detected,33 mobile phone surface were qualified,the qualified rate was 16.50%.Qualified rate of mobile phone surface of HCWs in different departments as well as mobile phone disinfected by different modes were different(χ2 =13.46,10.24,respectively,both P 0.05).Conclusion The qualified rate of bacterial content on surface of HCWs’mobile phone is low,the awareness of hand hygiene of HCWs should be strengthened,regular cleaning and disinfection on the mo-bile phone can effectively reduce bacteria on the mobile phone surface.
