Usability problems and opportunities for improvement—nurses’ feedback.

Component	Usability problems	Suggested opportunities for improvement in future design	Example of nurse feedback
Rules	Can not customize rules to include each patient’s dry weight	Add customization capability to include dry weight	they have to have a dry weight...having the patient know a weight that is optimal where they are not overloaded or too dry
	Changing standards	Add customization capability to change rules according to new standards	There are also shifts from research…we’ve been using weight gain of 2 to 3 pounds for years...they decided that is really not helpful...they are still looking at weight change but if it is 4 pounds or more...
Dashboard: all patients	Anomalies	Allow edits or deletes	The nurse highlighted a spike in one patient’s weight explaining that it was not real because he was weighing himself with his cat so there is a need to delete anomalies
	Gaps in data	Improve the process to prevent gaps in data	with it (data) not always being downloaded everyday, I see this big jump and I go what am I to do with that?
Dashboard: individual patient views	Identifying uncontrolled cases	Control charts	if you do a control chart, there is a pattern that starts appearing before hand and then you can see what’s going on and pay more attention
Alerts	False positives	Add rules to reduce False Positives	I would like to trust that text is something I need to look at… because about 95% of the time the alerts have been normal…
			or we wanted that to happen so we get an alert for the weight drop and we wanted the weight to drop but it comes up as a high-risk
