This study explores the impact of technostress on the intention to use telemedicine applications (apps) in the post-COVID19 era, a period marked by the rapid popularization of such apps to mitigate COVID19 infection risks. Utilizing the Technology Acceptance Model (TAM), the study identifies variables and proposes a research model. A questionnaire survey involving 364 adults is analyzed through Partial Least Squares-Structural Equation Modeling. Results indicate positive significance for variables linked to the TAM (perceived usefulness, perceived ease of use, attitude, and intention to use). Notably, techno-complexity negatively affects perceived ease of use, while techno-unreliability negatively impacts perceived usefulness and ease of use. Surprisingly, techno-uncertainty has a positive effect on both perceived usefulness and ease of use. Techno-overload, although negatively impacting perceived usefulness and ease of use, does not reach statistical significance. The study underscores the need to consider both positive and negative aspects, including technostress, when evaluating telemedicine app usage. Additionally, recognizing the varying impact of technostress based on users' ICT(Information and Communication Technology) confidence levels is crucial. Overall, these findings contribute academically to telemedicine app adoption literature and hold industrial significance by providing a user perspective on these apps.

Background: The efficacy of telemedicine among cancer survivors is uncertain. The Smart After-Care Program (SAP), which is an interactive, smartphone-based remote health monitoring system, was developed to help patients manage their health after leaving the hospital. This study was designed to evaluate the efficacy of our remote health care program for lung cancer patients. Methods: We enrolled 50 patients with lung cancer. Self-monitoring devices were supplied to all patients, who were instructed to enter their daily vital signs and subjective symptoms to the Smart After-Care app. The app also provided information about rehabilitation exercises and a healthy diet for lung cancer patients. All patients received health counseling via telephone once a week and visited an outpatient clinic during weeks 6 and 12 to assess satisfaction with the SAP and changes in quality of life and physical performance. Results: Overall satisfaction with the SAP was very high (very good, 61.9%; good, 26.2%). In the multivariate analysis to identify factors affecting satisfaction, the distance between the patient's residence and the hospital was the only significant independent factor (p=0.013). Quality of life improved along all functional scales (p<0.05). Muscle strength significantly improved in the lower limbs (p=0.012). Two-minute walk distance also significantly improved (p=0.028). Conclusion: This study demonstrated that the SAP was acceptable for and supportive of patients with reduced pulmonary function after lung cancer treatment. The SAP was found to be particularly useful for patients living far from the hospital.

Background: This study aimed to determine: the perspectives of the patient cohort that underwent telehealth consultation and shoulder rehabilitation during coronavirus disease 2019 (COVID-19) and the differences in the patients' perspectives with the two different telehealth video applications (apps) used in the study. Methods: This is a prospective study carried out during the COVID lockdown period of April to July 2020. Thirty consecutive patients from the orthopedics department of a tertiary institute in India underwent their first-ever session of a video app-based (Zoom or WhatsApp) telehealth consultation with shoulder rehabilitation exercises on a handheld mobile, tablet, or laptop device. After the virtual consultation, the patients were sent a validated telehealth usability questionnaire (TUQ) to evaluate their perspectives. Scores obtained from the TUQ were the primary outcome measure. Results: The study was completed by 30 patients (16 men and 14 women) with an average age of 56 years (range, 20-77 years). The patients who contacted us during the lockdown period with either a stiff shoulder or a conservatively treated shoulder fracture were included in the study. The average TUQ score was 13.6 (median, 14.5; range, 6-21) out of a maximum of 21 points. Eighty percent of the patients were satisfied and found the telehealth service useful. Use of the Zoom app scored significantly higher (median, 17; average, 15.6) than the WhatsApp app (median, 8.5; average, 9.6) (p=0.004). Conclusions: Patients who received telehealth consultation and shoulder rehabilitation were overall satisfied. Telehealth apps with advanced video calling features such as Zoom should be preferred for higher patient satisfaction.

본 연구의 목적은 최근 확산되고 있는 국내 비대면 의료 서비스 애플리케이션의 서비스 속성과 소비자 반응을 정확히 평가하고 각 서비스간 차별성을 시각화하기 위한 방안을 모색하는 것이다. 이를 위해 국내에서 서비스 중인 주요 6개 비대면 진료 애플리케이션의 구글 플레이스토어 사용자 리뷰 데이터 총 2만 건을 수집하였다. 수집된 데이터에 대해 문장 단위로 분리한 후, BERTopic 모델링 기법을 적용하여 각 문장이 속한 서비스 속성에 대한 토픽을 도출하였다. 다음으로 미세조정된 KoBERT 모델을 통해 각 문장의 토픽에 대한 감성 점수를 예측하였다. 분석 결과, 사용자 리뷰로부터 애플리케이션 속성과 진료 속성 두 가지 범주 아래에서 각각 5개와 3개의 서비스 특성 토픽이 발견되었다. 애플리케이션 속성으로는 '예약 시스템', '사용 용이성', '재고 확인', '디자인', '안정성' 등이, 진료 속성으로는 '원격 의료적 속성', '편의성', '배송' 등이 도출되었다. 각 애플리케이션은 이러한 속성들에 대해 다른 수준의 감성 점수를 보였다. 주성분분석을 통해 속성별 감성 점수를 축약하여 2차원 공간 상의 포지셔닝 맵을 생성하였다. 결과적으로 본 연구는 비대면 진료 애플리케이션 사용자 리뷰 텍스트를 바탕으로 실증적 통계 방법과 텍스트 마이닝 기술을 접목하여 서비스 속성 도출, 감성 분석, 제품 포지셔닝 이라는 일련의 체계를 제시하고 있다. 이는 비대면 진료 애플리케이션의 서비스 품질과 소비자 반응을 객관적으로 진단할 수 있는 효과적인 방안이 될 것으로 기대된다.
