Abstract

Claims (53)

1. A method for generating a profile concerning prescription therapy practices of at least one physician in a therapeutic area of interest, comprising the steps of:

(a) receiving a plurality of historical de-identified patient prescription records corresponding to prescriptions issued to at least one de-identified patient by at least one physician, each record including de-identified patient identification number, dosage, and prescription product information;

(b) receiving user-specified information defining a subset of the historical de-identified patient prescription records;

(c) extracting at least one relevant historical de-identified patient prescription record from the received historical de-identified patient prescription records based on the subset;

(d) for each de-identified patient, comparing dosage and prescription product information contained in a first extracted historical de-identified patient record with dosage and prescription product information contained in a second extracted historical de-identified patient record; and

(e) for each comparison made in step (d), categorizing a prescription based on a change in dosage or prescription product.

2. The method of claim 1 , wherein the step of receiving user-specified information further comprises receiving information concerning an observation period.

3. The method of claim 1 , wherein the step of extracting de-identified patient prescription records further comprises discarding a historical de-identified patient prescription record having an eligibility of shorter duration than the observation period.

4. The method of claim 1 , wherein the step of categorizing prescriptions further comprises categorizing a prescription of a product as a new therapy start when a de-identified patient has had no other prescriptions in a therapeutic area to which the product pertains.

5. The method of claim 1 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as a therapy switch when a de-identified patient has had no other prescriptions of the product, and when the de-identified patient has had a prescription of a second product within a therapeutic area to which the product pertains that was not prescribed on the same day as the prescription.

6. The method of claim 1 , wherein step of categorizing prescriptions further comprises categorizing a prescription as an add-on therapy when the de-identified patient had no other prescriptions for the product but had a prescription for a second product within the therapeutic area to which the product pertains that was prescribed on the same day.

7. The method of claim 1 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as a titration decrease when a de-identified patient has previously had a prescription for the product at a higher dosage.

8. The method of claim 1 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as a titration increase when a de-identified patient has previously had a prescription for the product at a lower dosage.

9. The method of claim 1 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as continued therapy when a de-identified patient has previously had a prescription for the product at the same dosage.

10. A method for generating a profile concerning prescription therapy practices of at least one physician in a therapeutic area of interest comprising the steps of:

(a) receiving a plurality of historical de-identified patient prescription records corresponding to prescriptions issued to at least one de-identified patient by at least one physician, each record including de-identified patient identification number, prescription product information, date dispensed, dosage, number of days supplied, and refill information;

(d) for each de-identified patient, comparing dosage and prescription product information contained in a first extracted historical de-identified patient record with dosage and prescription product information contained in a second extracted historical de-identified patient record;

(e) for each comparison made in step (d), categorizing a prescription based on a change in dosage or prescription product;

(f) extracting at least one relevant historical de-identified patient prescription record from the prescriptions categorized at step (e) based on the refill information;

(g) for each de-identified patient, determining a refill due date based on the dosage and the number of days supplied for a first prescription;

(h) for each de-identified patient, comparing the refill due date of the first prescription with the date dispensed for a second prescription; and

(i) for each comparison made in step (h), categorizing the de-identified patient based on the duration between the refill due date of the first prescription and the date dispensed for the second prescription.

11. The method of claim 10 , wherein the step of receiving user-specified information further comprises receiving information concerning an observation period.

12. The method of claim 11 , further comprising a step of discarding, after step (e), a historical de-identified patient prescription record for a de-identified patient having more than one physician during the observation period.

13. The method of claim 11 , wherein the step of extracting de-identified patient prescription records based on refill information further comprises discarding a historical de-identified patient prescription record not having a refill due within the observation period.

14. The method of claim 10 , wherein the step of categorizing prescriptions further comprises categorizing a prescription of a product as a new therapy start when a de-identified patient has had no other prescriptions in a therapeutic area to which the product pertains.

15. The method of claim 10 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as a therapy switch when a de-identified patient has had no other prescriptions of the product, and when the de-identified patient has had a prescription of a second product within a therapeutic area to which the product pertains that was not prescribed on the same day as the prescription.

16. The method of claim 15 , further comprising a step of discarding, after step (e), a historical de-identified patient prescription record for a prescription categorized as a therapy switch.

17. The method of claim 10 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as a titration decrease when a de-identified patient has previously had a prescription for the product at a higher dosage.

18. The method of claim 17 , further comprising a step of discarding, after step (e), a historical de-identified patient prescription record for a prescription categorized as a titration decrease.

19. The method of claim 10 , wherein the step of categorizing prescriptions further comprises categorizing a prescription as a titration increase when a de-identified patient has previously had a prescription for the product at a lower dosage.

20. The method of claim 19 , further comprising a step of discarding, after step (e), a historical de-identified patient prescription record for a prescription categorized as a titration increase.

21. The method of claim 10 , wherein the step of categorizing the de-identified patient based on the duration between the due date of the first prescription and the fill date of the second prescription further comprises categorizing the de-identified patient as persistent if the duration is shorter than a predetermined number of days.

22. The method of claim 21 , wherein the step of categorizing the de-identified patient based on the duration between the due date of the first prescription and the fill date of the second prescription further comprises categorizing the de-identified patient as non-persistent if the duration is greater than a predetermined number of days.
