Practices are increasingly replacing their ambulatory EHR systems, with replacement rates rising by 20% since 2011 due to issues like poor vendor support and system inefficiencies. Before making a switch, practices should evaluate their current EHR system by considering factors such as vendor responsiveness, technical improvement commitments, ownership stability, and the impact on organizational goals and productivity. If replacement is deemed necessary, practices should seek a new vendor that offers rapid implementation, smooth data migration, and superior service.
