Data collection activities (observations, in-field interviews, documentary analysis and quantitative data generated from the PERFECTED ERP implementation checklist) will determine the staff training and cultural changes required to implement and maximise adherence to the PERFECTED ERP. Simultaneously, enabling the identification and exploration of areas of optimised, satisfactory and sub-optimal care. By working in partnership within and across the partner wards, action plans to address sub-optimal care will be generated, implemented and reviewed. Findings will inform the best ways to optimise care via the implementation of the PERFECTED ERP. Knowledge generated during this study will be used to develop an ERP and staff training manual. This will aid implementation of the intervention arm of a latter Cluster Randomised Control Trial (Work Package 3), ensuring the PERFECTED ERP can be utilised in the real world.
