|Official Title:||OptiVol® Care Pathway|
- Compare the Time to Initiation of Clinical Action Prompted by an OptiVol Threshold Crossing Between Monthly and Quarterly Review of Cardiac Compass Trends With OptiVol [ Time Frame: 1 year ]
- Compare Changes in Subject Self-care Over Time in the Monthly Review Arm vs. Quarterly Review Arm [ Time Frame: 1 year ]
There are 3 summary scale scores for the Self-Care of Heart Failure Index (SCHFI) form: self-care maintenance score (Section A), management score (Section B), and confidence score (Section C). Each scale score is standardized to a 0 to 100 range, with 0 indicating the worst and 100 indicating the best performance for each scale score.
Here, changes in each scale score between 6 month follow-up and baseline and between 12 month follow-up and baseline are the secondary outcome measures. Specifically, change at 6 (or 12) month follow-up is calculated as a scale score at 6 (or 12) month follow-up subtracts that at baseline. These changes range from -100 to 100 with 0 indicating no change at all, -100 indicating maximum decrease and 100 indicating maximum increase that is possible from baseline for a self-care scale score.
- Identify Patient Groups Who Are More Likely to Have Clinical Actions Triggered by Monthly Rather Than Quarterly Reviews [ Time Frame: 1 year ]The binary outcome of having clinical actions taken (Yes/No) is recorded within one month interval for the monthly review group, and within three months interval for the quarterly review group. To make the endpoints of both groups comparable, data from monthly review group are converted as they were collected quarterly. For example, the month 1, 2 and 3 visits of monthly review group are combined as one visit. If there is at least one action taken in any of these three monthly visits, the action taken variable for the combined visit will be recorded as 'yes'. Unscheduled visits in both groups are lumped to the next quarterly time point.

Experimental: Monthly Review Arm
Patients enrolled at centers that are assigned to the monthly review arm will have their device data reviewed monthly
Other: Monthly Review Arm
Monthly review of Cardiac Compass Trends with OptiVol. This intervention is related to disease management.
Active Comparator: Quarterly Review Arm
Patients enrolled at centers that are assigned to the quarterly review arm will have their device data reviewed every 3 months
Other: Quarterly Review Arm
Quarterly review of Cardiac Compass Trends with OptiVol. This intervention is related to disease management.
