I have not discussed the refill/renewal process.
One of the clear return on investment cases for e-Prescribing is the notion that a pharmacy can initiate a renewal request rather than requiring the clinician's office's to process a patient call.
A patient simply walks into a pharmacy and asks for a renewal. If no refills are available, the pharmacy system autogenerates a renewal transaction which is sent to the original prescribing physician's electronic medical record system. Once there, it appears in a Task or "To Do list" for physician approval. Once approved, the prescription is sent back to the pharmacy to be filled. Refill requests can also be generated via the pharmacy�s web page or for a maintenance medication, via a chain�s web site, a patient can setup automatic dispensing of refills every 30 days (or whatever frequency) and then the patient receives a call and/or email when the prescription is ready. If there are no refills left, then the pharmacy will initiate the refill request so that the prescription will be ready when the previous dispensing is used up.
There are a few tricky informatics and workflow issues such as
1. How do you match the renewal and the original prescription?
If the original new prescription was sent electronically, the EMR or e-prescribing system can insert a unique identifier for the patient / med into the prescription. This identifier is stored in the pharmacy system and echoed in the NCPDP standard refill request transaction. There is a 100% match if the EMR / e-prescribing system has been coded correctly.
Thus all EMR vendors and EMR self builders should create and send prescriptions electronically with this unique identifier. Then, as refill requests begin to flow, they will be easily matched in the EMR workflow.
If a new prescription was not sent electronically, it will be matched based on the prescriber's physician identifier. If the physician is registered with a SureScripts Prescriber ID (SPI), then the pharmacy will send a refill request automatically at any time a patient calls into the pharmacy and there is a need for physician approval to continue the therapy. This is completely automated in the pharmacy system and applies to any prescription in the system prescribed by that doctor.
When a refill request comes in without the unique matching identifier, it can still be matched automatically in many cases. The refill request will have the patient demographic information, especially the last name and birth date, and will have the NDC of the dispensed medication. By finding the patient using last name and birth date and then using the NDC to identify the therapeutic class by using the EMR�s drug file and then matching that class against the patient�s active med history list, the EMR can provide an exact match or narrow down to a couple medications for the prescriber to select for the refill approval or denial.
2. What do you do if the original prescribing physician is out of the office?
In our all our various workflow implementations that create physician work queues, we need to think about coverage patterns. Typically, we enable covering physicians to examine the work queues of other physicians or enable support staff to monitor queues so they can escalate pharmaceutical renewals and other time sensitive notifications.
Here's the current status of Pharmacy Initiated renewals in the US and Massachusetts:
Surescripts/RxHub currently has over 50,000 active physicians in the network across the country. Approximately 60% of these clinicians are using a certified EMR system (i.e. Allscripts (Touchworks and Healthmatics), NextGen, eClinicalWorks, Kryptiq/GE, Epic etc.). In July 2008 over 35% of the 6.5 million e-prescription transactions processed were refill requests and refill responses. Half of these transactions were processed by EMR users via pharmacy initiated electronic refill transactions and the corresponding electronic refill responses (using NCPDP Refill Request and Refill Response standard transactions and not New Prescriptions).
In July 2008 in Massachusetts there were about 25,000 pharmacy generated electronic prescription renewal requests going into EMR systems and being responded to (approved or denied) by clinicians and sent back to pharmacies electronically.
Historically, Pharmacy Initiated Renewals were supported mostly by stand alone eRx applications, but now, this transaction is supported by EMRs. Over the next year, the large academic systems in Massachusetts will plan to include these transactions and this workflow in their EMRs. The end result will be a further decrease in the administrative burden of medication management on physician offices, reducing costs and enhancing patient service.
