An analysis was performed during 2001–2002 in Michigan, USA. In a pharmacy belonging to the pharmacy chain Punches Pharma Plus, Lin et al. [8] evaluated the impact of a robotic dispensing machine on the preparation of unit dose packs. A retrospective study was performed on the process of preparing unit dose packs before and after the installation of the robotic dispensing machine. Overall, a significant saving in time was registered for the preparation of unit dose packs. However, the saving in time occurred only if the staffing level was adapted to the changed requirements.
