Impact of the Four-Hour Rule/National Emergency Access Target policy implementation on emergency department staff: A qualitative perspective of emergency department management changes.

Policy implementation is a complex process that had both positive and negative consequences on how ED staff managed the implementation of the 4HR/NEAT policy and how it changed their work environment. Understanding the perceptions of staff involved in policy implementation has significance for the design of future implementation strategies. The biggest insight from the present study is that ED management is very complex and the policy generated multiple positive and negative changes demonstrating the wide range of processes involved in this area of health services research.
