ABSTRACT
The COVID-19 pandemic has seen the advent of novel medical devices and practices. Demand for quality healthcare services rose exponentially which eventually led to accessibility becoming a major issue of concern. In addition to this, in-person consultations and various other conventional treatment methods were proven to be problematic. Limitations of traditional health care systems such as in-person consultations were highlighted, and conventional treatment methods have proven to be problematic. As an alternative approach, telehealth services are now gaining recognition due to their high efficiency, ease of use, and state-of-the-art technology. In this article, trends of telemedicine and its evolving popularity across the medical community due to the pandemic and beyond are studied and highlighted. An online survey form was circulated to 42 medical practitioners and interns to analyse the growing interest in telemedicine. The questionnaire covered the physicians' perspectives, preferences, experiences, and other important aspects of home-based teleconsultation. Based on the responses collected from doctors and medical interns, 14.2% disapproved, whereas 38.1% favoured and 47.6% showed a neutral response to the teleconsultation. More than 50% of the respondents claim the process to be time-consuming and 42% of them perceived it to be the other way round. 4.8% of the doctors preferred it to be only through computers whereas 45.2% per cent preferred consultation through smartphones and 50% of them preferred it be both ways. More than half (59.5%) of the doctors preferred the pandemic scenario and the remaining for its continued usage post-pandemic. Although India has the world's second-largest online market, a major population in India is digitally illiterate according to the Digital Foundation of India. Thus, it is important to devise telehealth technology that is simplest to use to reach also the economically backward patient communities.
ABSTRACT
Due to the ongoing pandemic, various types of facemasks such as certified N-95, non-woven fiber and fabric/textile masks are being used as an essential protective measure to reduce the risk of spread of the SARS-Cov-2 virus. The aerosols size-dependent filtration efficiency and breathing resistance of these masks were tested before and after sterilization by five different methods for two flow rates (20 and 90?L/min) conditions corresponding to regular breathing rate and moderate/strenuous exertion, in the particle size range 0.3?10?µm. Sterilization techniques used here are autoclaving (30 and 60?minutes), dry air oven heating (30 and 60?minutes), ionizing irradiation (15 and 25 kGy), hot water washing with and without detergent and immersing in a 10% concentration of liquid hydrogen peroxide for 30?minutes. Further, the filtration efficiency of each type of masks is also studied with laboratory generated two-order higher aerosol concertation. The certified mask has the most outstanding filtering efficiency among all the other type of facemasks. The ionizing radiation causes a significant reduction in filtration efficacy, so that it is not recommended for sterilization purpose. The best method to sterilize certified N-95 masks without affecting their performance is by using dry air heating with temperature ranging from 70?80 °C. The performance of the cloth and surgical masks is found to be comparable for both flow conditions. As an affordable sterilization method, hot water washing is recommended, which does not deteriorate the fabric masks efficiency and can be used by the common people. The recommended masks for the general people are textile/fabric masks which serves fit for the purpose than non-woven masks because it can help to reduce non-biodegradable waste (facemask) and prevent respiratory droplet transmission. The non-woven mask can be sterilized with dry heat, hot water wash and autoclave.
