What is the minimum standard for vital signs reassessment?

The minimum standard for vital signs reassessment is every 15 minutes or as clinically warranted. This frequency is based on the need to effectively monitor the patient's condition, especially in situations where there may be changes in the patient's clinical status. Reassessing vital signs every 15 minutes allows for timely detection of deterioration or improvement, which is critical in emergency medicine.

In practice, the interval may vary depending on the patient's stability and underlying conditions; thus, the emphasis on "or as clinically warranted" implies that healthcare providers should use their clinical judgment to determine the appropriate timing for reassessment beyond the 15-minute standard when necessary. For example, a patient with a rapidly changing condition may require more frequent monitoring, while a stable patient may require less.

Other intervals, such as every 30 minutes or every hour, may be appropriate for certain situations, but they do not reflect the minimum standard expected in dynamic environments such as emergency care. Similarly, assessing every 5 minutes might be excessive unless indicated by significant changes in the patient's condition.
