Background: Tele-nursing is considered one of the most important technological events of
the late (twentieth) century as the gateway to modern nursing care. The aim of tele-nursing is to
improve patient safety, quality of care, and is considered a quick access to nursing care by
overcoming the geographical barriers. Aim: This study aims to determine effect of tele-nursing
about life style modification on health outcomes of rheumatic heart disease patients during COVID-
19 pandemic. Design: A quasi-experimental research design has been utilized in this study (Two
groups study and control). Setting: The study was conducted at Sohag University Hospital in Egypt.
Subjects: Based on the population, 60 patients were chosen as the sample size was divided in to
two groups, control (30 patients) and study (30 patients). Tools:1) A Self-administered
Questionnaire (pre/post-tests), (2 Mini Nutritional Assessment short-form (MNA®-SF) (pre/post-
test), (3 The Exercise Adherence Rating Scale (EARS) and (4 Deep venous thrombosis risk
assessment tool . Results: There were a highly statistically significant differences between both
groups regarding knowledge level, pepper nutrition, exercise adherence (P≤ 0.001).There was a
positive correlation between body mass index and prevention of deep venous thrombosis among
study group patients post- implementing of tele-nursing during COVID-19 (r= .580 at P≤ 0.01).
Conclusion: it is an effective strategy, telenursing has been proven to give appositive result for
improving health outcomes of rheumatic heart disease patients. Recommendations: Replication of
the study using large probability sampling. Enhance telenursing use in nursing practice, and apply
telenursing via follow up phone services to improve patient's adherence to a healthy regimen.
