Background: Health care providers need a better understanding of virtual care to recognise and use it for service delivery. Aim: To provide a more comprehensive definition of the concept of virtual care. Method: This study was conducted based on Walker and Avant's concept analysis method. A comprehensive review of the published texts in English from 2012 to 2022 was performed using the PubMed, Web of Science, Scopus, ProQuest, Science Direct, Ovid, CINAHL and Google Scholar databases. Results: The main aspects and attributes of virtual care, including the use of any information and communication technology in various formats such as platforms, telephone calls, messages, email consultation, remote monitoring, secure and two‐way digital communication between health care providers and patients, the possibility of providing remote care synchronously or asynchronously, more interaction between patients and caregivers, the possibility of transferring information between patients and health care providers and within the teams themselves, symptom management, sending diagnostic results in the form of video visits, and providing follow‐up care, are attributes that distinguish virtual care from telehealth, telemedicine and other methods of providing remote healthcare services. Conclusion: Considering the positive and negative consequences of implementing virtual care, the findings of this study developed a basis for an operational definition of the concept so that providers can understand the meaning of virtual care and consider it when providing virtual care to patients. The findings of this study can be used in many international and national contexts in the health care system and in future studies on interventions to increase the use of virtual care.

Introduction: Preterm infants are under different procedures as a part of their care in the Neonatal Intensive Care Unit (NICU). Reduction of their stress and to provide rest opportunity for them is very important. In this regard, clustering of routine care is recommended. The aim of this study was to compare of physiological responses in preterm infants to clustered care with three and four noninvasive procedures (Respectively 7 & 10 point stressor)., Methods: A randomized crossover clinical trial performed in NICU of Al-Zahra teaching hospital, Tabriz, Iran in 2013. Thirty one preterm infants were studied at 32 weeks gestational age. The tool for data collection was a researcher-made data gathering sheet that personal information and measurement of primary outcomes (heart rate, respiratory rate and blood oxygen saturation) were recorded. The analysis of data was done with use of mixed model method at 0.05 significant level., Results: Mean of oxygen saturation in before, during and after of clustered care with three procedures were respectively 97.52, 97.32, 97.84 and four procedures 97.29, 97.16, 97.35, heart rate of three procedures 146.26, 149.90, 149.97 and four procedures 146.45, 150.39, 151.13, respiratory rate of three procedures 51.68, 48.87, 47.71 and four procedures 51.71, 50.26, 52.35 that all of them were at normal range. Significant differences were not found between mean of physiological responses in two interventions., Conclusion: There was no significant difference between clustered care with four and three procedures. Both of them could be recommended for preterm infants in 32 weeks.
