I am working on a little newsletter article that talks about the finer points of ePrescribing for my eCW clinics. I scrounged about until I found a Surescripts ePrescribing Guideline document that laid out the basic formatting of ePrescriptions and used it as the basis of the article. I believe that the information here is pretty solid, but if someone knows something to the contrary, please let me know. I thought I would share it in case it’s helpful to anyone else….
==================================
Understanding ePrescribing
ePrescribing is quickly becoming the standard method for transmitting prescriptions to pharmacies. Many users may be confused about the precise requirements and structure of ePrescriptions.
When a medication is sent electronically to the pharmacy, eClinicalWorks converts the prescription information into an electronic message which is then transmitted to the patient’s pharmacy. The message is designed to contain the following information:
• Patient’s full name and street address
• Prescribing provider’s full name and clinic address
• Date of the prescription
• Name, strength, dosage form, and quantity of drug prescribed
• Directions for use
• Number of refills
• Provider’s electronic signature
While the patient and provider information is pulled automatically from eClinicalWorks, the remaining elements of the message come from the information entered into Rx section of the treatment window. The first part of the eprescription message is comprised of the medication name, strength, and formulation. Together, these three fields cannot exceed 105 characters.
The second segment of the message is designed to convey the Take, Route, Frequency, and Duration information. Information in these fields cannot exceed 140 characters cumulatively. The third segment of the message conveys the amount to dispense and the number of refills. Lastly, ePrescribing requires each prescription message to include the medication’s NDC; custom medications that are not linked to an NDC code cannot be eprescribed.
In order for a prescription to be eprescribed, information in each field must be entered in a specific format.
• Medication name: free text (alpha and numerical allowed) information, primarily selected from the drug dictionary
• Strength: a number space unit format, example 50 MG or 100 mg-25 mg
• Formulation: free text, either an entry selected from the “formulation” pick list or typed into the field, example: tablet or capsule.
• Take: free text, either an entry selected from the “take” pick list or an entry typed into the field, example: one capsule.
• Route: free text, example: orally
• Frequency: free text, example: once a day or in the morning
• Duration (optional) number space unit, example 30 days (any information added after the unit will be truncated)
• Dispense Number space unit code*, example: 30 U2 (any information added after the unit will be truncated)
• Refill: a single number only (any information added after the number will be truncated)
*The dispense field sends the unit type as a code to the pharmacy. If no unit code is entered into the “Dispense” field of the prescription window, eCW looks to the Formulation field for a unit description and converts that unit into a unit code with a matching description. (I will attach the table of unit codes and definitions.)
