Risk of self-contamination because of improper doffing of personal protective equipment: A randomised cross-over study

BACKGROUND AND AIMS: Many health care staff have been pressed into coronavirus disease-19 patient care with little experience of working in bio-hazard zones because of the overwhelming requirements of manpower. They wear personal protective equipment (PPE) and follow all rules for their safety. Howe...

description BACKGROUND AND AIMS: Many health care staff have been pressed into coronavirus disease-19 patient care with little experience of working in bio-hazard zones because of the overwhelming requirements of manpower. They wear personal protective equipment (PPE) and follow all rules for their safety. However, despite precautions, during doffing, they carry a risk of self-contamination. This randomised cross-over study assessed the risk of self- contamination because of improper doffing of PPEs. METHODS: A colourless lotion that glows with a bright-green fluorescent hue under ultraviolet light was applied to simulate germ contamination in various health care workers (HCWs) who volunteered for the study. The primary objective of this study was to know the percentage of HCWs getting self-contaminated. The secondary objectives were to assess which portions of the body get maximally contaminated and infestation of germs on which portions of the PPE carry more risk of self-contaminating after doffing. RESULTS: A total of 152 doffings by 76 participants were analysed, and the volunteers self-contaminated in 43 doffings (28.28%). In 18 of these 43 doffings, self-contamination was noted at more than one location. The most commonly contaminated areas were the arms (33%), clothes on the abdomen (24%), and areas in the lower limb (23%). Germ infestation on the upper parts of a PPE is 2.39 times more likely to cause self-contamination after improper doffing. CONCLUSION: Faulty doffing resulted in self-contamination in 28.28% of all doffings. Risk is 2.39 times more when germs are nested in the upper body portions of the PPE suit.
