Telemedicine is a health service that provides diagnosis, treatment evaluation, preventive medicine by using information and communication technologies between distant places and aims to improve the health of individuals and society. Covid-19 pandemic especially having chronic illness people could not go to hospitals and their follow-up became a problem. Through remote communication and information technologies in the follow-up of asthma patients there is a need for studies on the effectiveness of using telemedicine methods is seen. With the use of remote communication channels, it is aimed to increase patient-physician cooperation, and to ensure effective disease control of patients without applying to a hospital. We included 328 patients between the ages of 18-65, whose diagnosis of asthma was confirmed by pulmonary function tests. As the control group, data from the hospital records of the participants for a period of 6 months before the pandemic period were used. When the current data of the participants were compared with the face-to-face data before follow-up with telemedicine, no statistically significant difference was found (p> 0.05). Disease follow-up with telemedicine is predicted to be a good alternative to traditional face-to face follow-ups in selected patient groups. Our study also supports this situation.
