This page is part of the U.S. Physical Activity IG (v1.0.0: STU 1.0) based on FHIR R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions 
| Official URL: http://hl7.org/fhir/us/physical-activity/StructureDefinition/pa-observation-evs-min-per-week | Version: 1.0.0 | |||
| Standards status: Trial-use | Maturity Level: 2 | Computable Name: PAObservationEVSMinutesPerWeek | ||
A profile for observations that capture a patient’s average minutes per week of moderate-to-vigorous physical activity.
This is a calculated value, created by multiplying the first two components of the Exercise Vital Sign - EVS Days per Week and EVS Minutes per Day. It can be compared to national guidelines based on age to assess patient physical activity level.
