A Cross-sectional Study on Adherence to Personal Protective Equipment among Healthcare Workers during COVID-19 Pandemic in a Tertiary Care Centre, Tamil Nadu, India

Abstract

Introduction: Personal Protective Equipment (PPE) provides physical barrier against hazardous injury or infectious agents. With the outbreak of COVID-19 pandemic, PPE plays a vital role with face mask and gloves are being most essential. The frontline Healthcare Workers (HCW) utilises them to minimise the risk of contaminated contact or infected droplet exposure. Aim: To evaluate the appropriate use of PPE among healthcare workers in tertiary care hospital. Materials and Methods: This cross-sectional study was conducted in SRM Medical College Hospital and Research Centre, Potheri, Chengalpet district, Chennai, Tamil Nadu, India, from February 2021 to May 2021, on utility of PPE among the healthcare workers. There were a total of 273 participants including doctors, residents (postgraduate)/interns, nurses and laboratory technicians. A predesigned questionnaire was utilised to collect information, apart from observation of their PPE practice and 360 degree observation from peers were also used to evaluate. Statistical analysis was done using Chi-square test, Fisher’s-exact test and logistic regression model. Results: Among 273 HCWs, there were 58 (21.24%) doctors, 163 (59.71%) residents and interns, 19 (6.96%) nurses and 33 (12.09%) technicians. There was no association in the frequency of mask with the type of HCW (p-value=0.217). However, the usage frequency of gloves (p-value=0.003), face shield/goggles (p-value=0.004), disposable gown (p-value=0.001) and doffing according to protocol (p-value=0.001) showed statistically significant difference between the category of HCWs. Conclusion: In this study, PPE adherence was high among HCW; however, there was a subtle difference in compliance across the varied groups of healthcare professional and type of PPE used. The PPE compliance among HCW cannot be assumed to be good blindly; frequent official training programs, availability of PPE logistics along with scrutinisation regarding its appropriate usage and discarding at regular intervals minimises the non compliance and also helps in curtaining the COVID-19 transmission.
