A perspective on the scope of videoconferencing-based telemedicine in respiratory diseases outpatient clinic

Telemedicine is rapidly expanding across various fields worldwide. While it finds application in respiratory diseases due to the imperative need for protection against the risk of transmission and the close monitoring of patients with chronic diseases, there is a scarcity of publications detailing telemedicine experiences in respiratory diseases. This study aims to retrospectively evaluate the prospective management of patients with respiratory diseases through videoconference-based telemedicine, intending to establish a foundation for its judicious application in pulmonology cases.

In this descriptive study, anonymized medical records of all 478 patients assessed via videoconference-based telemedicine over an eight-month period from June 2020 to February 2021 were reviewed. The analysis included demographic characteristics, disease history, attendance methods, the necessity for in-person physical examination after the initial videoconference (VC) session, the inclusion of investigations, pre-diagnosis, diagnosis processes, follow-up period, and outcomes. Follow-up data for all patients included in the study were reviewed at the end of June 2021.

Median age of the patients was 55 (44-67), with a male predominance of 55%. Approximately 30% resided in a city other than the one in which the physician offering telemedicine was situated. Seventy-nine (16.7%) individuals received telemedicine via VC sessions without the requirement for any in-person examinations. The most prevalent disease among those who applied for telemedicine was asthma. Median duration of the initial VC session was 13 (8-18) minutes. At least half of the individuals seeking videoconference-based telemedicine for chronic respiratory disorders, such as asthma, COPD, and interstitial lung disease, had previously been followed by either the telemedicine provider or another physician in the same hospital. However, the vast majority of telemedicine applications in disease categories such as COVID, post-COVID, pulmonary nodules, and lung cancer were submitted by first-time applicants.

This pioneering study suggests that videoconference-based telemedicine may be an alternative/complementary tool for patients, particularly those with chronic respiratory diseases.
