The primary prescriber attachment for inpatients is the "Attending" prescriber (synonymous with "Most Responsible Healthcare Provider"). Each facility will need to firm-up processes for ensuring that this attending designation is updated as clinicians handover responsibilities from on-call, cross-coverage or rotation assignments.
Support staff usually do this when patients move to and from wards. Prescribers participate by keeping a close eye on their patient and team patient lists, and being ready to adjust attending accountabilities as needed.
