+## Workflow
+
+The `medication-refill` hook fires when a medication refill request for an existing prescription of a specific medication is received. A refill request may be made as part of an encounter or out-of-band through a pharmacy or patient portal. Since a prescription refill is requested outside of the prescriber's workflow, there often is not a user in context. Similarly, the encounter may be an auto-generated refill encounter or there may not be an encounter in context when the refill request is received. A CDS service may use this hook to deliver medication refill protocol guidance to a clinician. Given the asynchronous workflow of refill requests, the guidance returned by the service may be viewed immediately, or not.
+
+This hook does not fire for an initial prescription (see order-sign). "Re-prescribing" or replacing a previously active prescription with a new perscription for the same medication does not fire the medication-refill.
+
+## Context
+
+The set of medications in the process of being refilled. All FHIR resources in this context MUST be based on the same FHIR version. All FHIR resources in the medications object MUST have a status of _draft_.

## Workflow
-The `order-dispatch` hook fires when a practitioner is selecting a candidate performer for a pre-existing order that was not tied to a specific performer. For example, selecting an imaging center to satisfy a radiology order, selecting a cardiologist to satisfy a referral, etc. This hook only occurs in situations where the order is agnostic as to who the performer should be and a separate process (which might be performed by back-office staff, a central dispatch service, or even the ordering clincian themselves at a later time) is used to select and seek action by a specific performer. It is possible that the same order might be dispatched multiple times, either because initial selected targets refuse or are otherwise unable to satisfy the order, or because the performer is only asked to perform a 'portion' of what's authorized (the first monthly lab test of a year-long set, the first dispense of a 6 month order, etc.)

Note that the order isn't updated to include the performer in this situation, as the authorization of who could theoretically perform the order isn't changed by seeking fulfillment by a specific provider.
This "request for fulfillment" process is typically represented in FHIR using [Task](http://hl7.org/fhir/task.html). This resource allows identifying the order to be acted upon, who is being asked to act on it, the time-period in which they're expected to act, and any limitations/qualifications to 'how much' of the order should be acted on.
