Table 2.

Thematic analysis of free-text comments from 58 patient users and a focus group of 6 heart failure specialist nurse users of the remote monitoring platform. Two main themes are of positive and negative impacts. Different subthemes for each user group are nested within each theme. Examples of text data within each subtheme are provided as quotations.

Theme and Subtheme (examples)
Patient users		Heart failure specialist nurse users
Positive impacts
	Increased engagement and understanding: (“...makes me pay closer attention to my weight and blood pressure.”) Reassurance and security: (“I feel much safer...peace of mind knowing there is a team watching over me.”) More convenient: (“...makes me feel...protected without the inconvenience of being in hospital”; “...I don’t have to rely on nurses coming round to do blood pressure checks.”) Early abnormality detection: (“...makes it possible to take actions in advance to prevent heart attacks.”) Enhanced communication: (“...allows patients to express their concerns and knowing there is somebody there who will listen and reply to them.”)	Increased engagement and understanding: (“...promotes patients being more proactive in self-management of their condition.”) Enhanced usual care: (“...good adjunct to usual care, does not replace but enhances.”) Admissions avoidance: (“...we have avoided admissions”; “...useful way to...prevent hospital admissions.”) Early abnormality detection: (“...allows trends to be spotted more quickly and actions to be taken for patients deteriorating or at risk of hospital admissions.”) Medication optimizations: (“...useful aid when titrating medications remotely.”)
Negative impacts
	Lack of human interaction: (“...having a ‘human’ voice to talk to is far better.”) Information overload: (“I check it too often and read too much or too little into it.”) Technical issues: (“...when I can’t get it to connect it gets me very frustrated...”)	Increased workload: (“Sometimes can be difficult to manage the additional alerts”; “On-boarding can be complicated and time-consuming for staff.”) Accessibility limitations: (“...only suitable for those that are tech savy and access to a smartphone.”) Technical issues: (“Very much dependent on whether connections are good.”)
