Health metrics can be collected through various methods: 1. Electronic Health Records (EHR): EHR systems are designed to collect and store patient data systematically. 2. Wearable Devices: Devices like fitness trackers and smartwatches can monitor metrics such as heart rate and physical activity. 3. Manual Recording: Nurses often collect data manually during patient assessments. 4. Surveys and Questionnaires: Patient-reported outcomes are collected through structured surveys.
