|Electronic health records||Ease of access, interoperability with other electronic data repositories, data accuracy||Reduction in errors; decision support; accurate medication reconciliation to facilitate guideline adherence; if available, an effective patient portal to facilitate patient/caregiver engagement|
|Patient monitoring devices: e.g., scales, implanted devices, bioimpedance devices||Accuracy; false alerts; cost effectiveness; infrastructure/resource needs, including accurate data management and triage||Early warning and a reduction in morbidity|
|Wearable activity monitors||Accuracy||Physical activity coaching/adherence, early detection of arrhythmias (e.g., AF)|
|Smartphones||Need for more useful apps||Activity tracking, diet records, weight management, communication with HF team, prompts for medication adherence|
AF = atrial fibrillation; HF = heart failure.
