Healthcare providers are at risk of exposure to SARS-CoV-2 via droplets, respiratory secretions, and contact with contaminated surfaces. Personal protective equipment (PPE) is necessary for primary reliable prevention to treat patients with coronavirus disease 2019 (COVID-19). However, PPE shortages have had a significant impact on every medical facility, and outpatient clinics are especially vulnerable to shortages of medical supplies. During the first stage of the pandemic, efforts were made to reduce the use of medical supplies. Guidance and strategies were proposed to ration the use of PPE, including reusing it. However, reuse (wash) of isolation gowns has not been practically promoted despite these suggestions. Further, reusable products may have advantages for economic and ecologic reasons. We developed an adult universally sized, long-sleeved, 100% polyester, reusable/washable gown with liquid barrier protection. The isolation gown can be worn repeatedly through washing and subsequent disinfection, and it can withstand washing in 80°C hot water for 10 min and/or immersion in 0.05%-0.1% sodium hypochlorite for 30 min and then dried. This new gown’s liquid barrier performance is at Association for the Advancement of Medical Instrumentation level 1, even after 20 repeated uses with low cost. The choice of barrier level for gowns should be made based on the risk of contamination. However, the healthcare setting for COVID-19 patients varies greatly with not fully elucidated transmissibility. The newly made reusable isolation gown can be one option for treating COVID-19 patients especially in low-risk settings with economical advantage. Further, preparedness for reuse may have critical implications in extreme shortage. Reconsideration should be focused on reusable gowns with liquid barrier performance and their appropriate use.
