When an organization considers purchasing a patient Referral Management System (RMS), one of the first points management considers is whether or not its existing EMR/EHR can provide the missing functionality with an add-on, or perhaps already does but is not being used.
In general, use cases that are exclusive to employed healthcare providers working within the provider system will favor using an EMR alone. However, once an organization wants to do complex tiering of its networks and/or work with provider resources outside its organization, a Referral Management System becomes critical.
