Abstract

Provided is prescription dosage check system and method for ensuring safe and reliable prescription ordering and filling for a medication prescribed by a caregiver. The system includes dose range checking (“DRC”) and an alert system to prevent filling of a prescription where the prescribed dosage falls outside a dosage value or range for that medication, while minimizing nuisance alerts and alert fatigue.

Claims

1. A method of checking a prescription dosage using a device having a data terminal, a central processing unit, a central server, and an electronic patient record database comprising a plurality of electronic patient records and an electronic drug reference database, comprising:

entering an order into the data terminal, the order comprising a prescribed dosage of a medication for a patient;

uploading the order to the central server;

identifying a dosage or dosage range from the electronic drug reference database for the medication based on the medication prescribed and at least one patient parameter obtained from an electronic patient record for the patient contained in the electronic patient record database;

comparing the prescribed dosage with the identified dosage or dosage range;

determining whether the prescribed dosage falls above or below the identified dosage or outside the identified dosage range; and

generating and outputting an alert if the prescribed dosage falls above or below the identified dosage or outside the identified dosage range.

2. The method of claim 1, wherein the patient is a pediatric patient and the electronic patient record database is a pediatric electronic patient record database.

3. The method of claim 1, wherein the identified dosage or dosage range does not trigger an alert rate greater than 2.6%.

4. The method of claim 1, wherein if the prescribed dosage falls within the identified dosage range, then the order is filled by a pharmacist.

5. The method of claim 1, wherein the identified dosage comprises at least a maximum dosage and an alarmingly high dosage.

6. The method of claim 5, wherein when the prescribed dosage exceeds the maximum dosage but does not exceed the alarmingly high dosage, a soft stop alert is generated that can be overridden by the caregiver.

7. The method of claim 5, wherein when the prescribed dosage exceeds the alarmingly high dosage, a hard stop alert is generated that can be overridden by a pharmacist only upon communication between the caregiver and the pharmacist.

8. The method of claim 1, wherein the identified dosage comprises at least a minimum dosage and a highly ineffective dosage.

9. The method of claim 8, wherein when the prescribed dosage is less than the minimum dosage but not less than the highly ineffective dosage, a soft stop alert is generated that can be overridden by the caregiver.

10. The method of claim 8, wherein when the prescribed dosage is less than the highly ineffective dosage, a hard stop alert is generated that that can be overridden by a pharmacist only upon consultation with the caregiver.

11. The method of claim 1, wherein the identified dosage comprises at least a 1°

dosage range including a minimum dosage endpoint and a maximum dosage endpoint, and a 2°

dosage range including a highly ineffective dosage endpoint and an alarmingly high dosage endpoint where the 2°

dosage range encompasses the 1°

dosage range.

12. The method of claim 11, wherein when the prescribed dosage is outside the 1°

dosage range but is within the 2°

dosage range a soft stop alert is generated that can be overridden by the caregiver.

13. The method of claim 11, wherein when the prescribed dosage is outside the 2°

dosage range, a hard stop alert is generated that cannot be overridden by the caregiver alone, but can be overridden by a pharmacist only upon consultation with the caregiver.

14. The method of claim 1, wherein the identified dosage or dosage range is one or more dosages or dosage ranges selected from the group consisting of a 1°

dosage range including a minimum dosage endpoint and a maximum dosage endpoint, a 2°

dosage range including an ineffective dosage endpoint and an alarmingly high dosage endpoint, a minimum dosage range including a minimum dosage endpoint and a highly ineffective dosage endpoint, a maximum dosage range including a maximum dosage endpoint and a highly alarming dosage endpoint, a minimum dosage, a maximum dosage, an alarmingly high dosage, and a highly ineffective dosage.

15. The method of claim 1, wherein an electronic patient record of the patient contained in the electronic patient record database is updated with patient data in real time.

17. The method of claim 1, wherein the identified dosage or dosage range is determined by obtaining a dosage or dosage range based on the medication prescribed and at least one patient parameter from the electronic reference drug database and checking the obtained dosage or dosage range against dosage data for that medication contained in a different medication database, to generate the identified dosage or dosage range.

18. The method of claim 17, wherein the identified dosage or dosage range comprises at least two maximum dosage parameters selected from the group consisting of flat soft stop maximum dosage, flat hard stop maximum dosage, per kilogram soft stop maximum dosage, per kilogram hard stop maximum dosage, daily flat soft stop maximum dosage, daily flat hard stop maximum dosage, daily per kilogram soft stop maximum dosage, and daily per kilogram hard stop maximum dosage.
