Image quality in telehealth: challenges in developing countries
Abstract The purpose of this paper is to explore the underlying challenges in the telehealth environment in India and Pakistan that impede the delivery of high-quality images between a patient and health care professional. An exploratory study was conducted among healthcare professionals in India and Pakistan to assess their perceptions regarding image quality, which is used for the diagnosis and treatment. This cross-sectional qualitative study used semi-structured interviews with healthcare professionals in both India and Pakistan. The interviews were analyzed using a thematic analysis, which revealed three major themes. These themes being: ICT infrastructure and connectivity, high-quality images were produced by trained technicians in an organized telemedicine set-up; and image quality can be degraded by multiple transmissions. Findings indicate that in both countries the main underlying challenge is the lack of consistency in the network infrastructure between urban, rural and remote areas. Additionally, training patients to use hand-held devices to take high-quality images future could hold the key to improving the reliability and consequently the quality of images transmitted between patients and health care professionals.
