As with any quality improvement initiative, having data about both processes and outcomes is critical. Data collection should ideally begin when the ERP team is assembled, to show the team where they are starting. Length of stay is an easy way to monitor outcomes within an institution as it relates to recovery, organization, complications and cost. Readmissions and ED visits should also be monitored. However, it is also important to collect information about adherence to the different care processes included in the ERP in order to understand those outcomes and how to improve care.
