Method
Using the World Health Organisation’s Workload Indicators of Staffing
Need (WISN) methodology, a two-round Delphi consensus study with an
Expert Panel of UK hospital pharmacy managers was undertaken to develop
the Activity Standard for pharmaceutical care and to identify the time
unavailable for clinical work inherent in employing staff. Consenting
Panel members then tested the CPWC by calculating the staff resource
required for three staffing scenarios to determine whether it could be
reliably used by different operators.
