Decision: Change CarePlan.text from M andatory min = 1 to Must Suppor t min = 0 Add bullets to Careplan Profile Specific Implementation Guidance:   The original Assessment and Plan design in the CarePlan was to support the 'Assessment and Plan' from a narrative Progress Note. Systems have advanced significantly since the introduction of this requirement in 2015. Relaxing this to 0..1 allows more sophisticated systems to discretely encode a CarePlan while still allowing a narrative 'Assesment and Plan'   Alternatively, Assessment and Plan of Treatment may be included in various types of [Clinical Notes] , such as Progress Notes, History & Physical (H&P), Discharge Summaries, etc. Background and Rationale From 2015 CCDS From USCDI: Assessment and Plan of Treatment Health professional’s conclusions and working assumptions that will guide treatment of the patient.   We believe that the USCDI class of 'Assessment and Plan' may be too broad and generic. Our selection of CarePlan in DAF/Argonaut/US Core preceded  US Core Clinical Notes design The Assessment and Plan design in the CarePlan is confusing and, in hindsight, may not have been the best choice. Nevertheless, it is worth noting that it has been a part of the US Core since Argonaut DSTU in 2017 and has thus been widely adopted. The suggested modifications provide a roadmap for future developments and allow systems flexibility in representing care plans.
