The National Acuity Audit is a bi-annual audit of patient acuity across NHS Wales.

For the purpose of the bi-annual audit, patient acuity data is collected during the months of January and June, at 15:00 hrs each day, as stipulated by the Chief Nursing Officer. The more data that is collected, the more robust and reliable picture of a ward’s caseload will be obtained.

Data must be recorded on every patient, 7 days a week, for the full calendar month for the period of the acuity audit.
