GRAPEFRUIT JUICE RULE REMINDERS (User's Manual, pgs. 390-402)

Grapefruit juice affects the levels of many medications. Welford Chart Notes has incorporated these warnings into its Patient Education Brochures, so you can warn your patients about this by giving them these Brochures when you start them on medications. But what if you want to warn them after the time when you first started them on the medication?

The answer is to write some Rule Reminders about drugs which interact with grapefruit juice. However, you probably don't want to remind the patient EVERY time you see the patient. You will probably want to warn the patient once, or perhaps remind the patient at some interval, such as once a year. In order to accomplish this, you need to keep track of which patients you have warned and when. The way to do this is to create your own user-defined Lab Test. Then, when you have reminded the patient, store this information in the user-defined Lab Test. Here's how:

1. Press View\Lab. Enter any user's name.

2. Press Utility\Vocabulary.

3. For Test Name, enter GRAPEFRUIT REMINDER. For Numeric, pick No. You can leave Units and Code Number and Synonyms blank. Press Ok.

You can review which drugs interact with grapefruit juice:

1. Press Libraries\Interactions.

2. For Drug Name, enter GRAPEFRUIT JUICE.

3. You can see that grapefruit juice interacts with quite a few drugs. The ones that have a severity of Moderate or above include amlodipine, atorvastatin, buspirone, carbamazepine, cisapride, cyclosporine, diazepam, felodipine, itraconazole, lovastatin, midazolam, nimodipine, nisoldipine, saquinavir, sertraline, simvastatin, sirolimus, terfenadine, triazolam, and verapamil. (Cisapride and terfenadine are no longer on the market).

You can't fit all of these into a single rule due to the limitation of 255 characters in a rule, but you can write more than one to cover all of them:

1. Press Libraries\Rules\Edit\Add.

2. For Rule, type in "(on amlodipine or on atorvastatin or on buspirone or on carbamazepine or on cyclosporine or on diazepam or on felodipine or on itraconazole or on lovastatin or on midazolam or on nimodipine or on nisoldipine or on saquinavir) and never had grapefruit reminder". Press <Tab>.

3. When asked if the rule is interpreted properly, press Yes (unless you mistyped it).

4. For Reminder, say "Remind not to drink grapefruit juice".

5. For Explanation, say "Grapefruit juice significantly alters the levels of these drugs".

6. If you want to include one or two references, you can add them at this time.

7. Press Ok to store this Rule Reminder.

8. Write a second Rule Reminder similar to the first, only for the Rule, type in "(on sertraline or on simvastatin or on sirolimus or on triazolam or on verapamil) and never had grapefruit reminder".

Note that these Rule Reminders will remind you only until you store a value for Grapefruit Reminder in the patient's Lab Book. If you want to remind the patient yearly, change the rule to read "and last grapefruit reminder > 1 year ago" instead of "never had grapefruit reminder".

 

 

 

When you open a patient's chart and the Rule Reminder appears, if you then remind the patient not to have grapefruit juice, you should record that fact in the patient's Lab Book under the test name GRAPEFRUIT REMINDER. You might even want to create a Contraction, like "grg", to stand for "Grapefruit reminder given", and place it into your note for documentation. Then, when you store the note if you have enabled Lab Book Parsing (System\Parser Options\Parse Lab Book is checked), the program will update the patient's Lab Book for you. (In version 3.9, the program will also have a Lab button right on the Rule Reminder screen so you can open the Lab Book on the spot and add the grapefruit reminder directly).

NEWS ON UPCOMING VERSIONS

We are beta testing a brand new Welford Chart Notes for Windows - SQL Version which we have developed over the past year. This version stores the program's data in Microsoft SQL Server, instead of in our own proprietary database. This allows users free access to their data, and allows the program to scale up to much larger installations without loss of performance. We also have added dozens of new features to version 3.9 (of both the SQL and the 32-bit versions), also undergoing beta testing. For example, in version 3.9 you will be able to print postcards or letters from the Appointment Scheduler reminding patients of upcoming appointments. The Image Utility has a new Effects button which lets you apply a huge array of filtering and special effects to your images, to make them sharper or easier to view. You can zoom the Lab Book Graph to full screen, and can view height and weight percentile graphs in standard format similar to published paper forms.
