I think we can all agree now that 90-day prescriptions are correlated with better adherence (and the percentage of retail 90-day scripts is going up). The latest study here is from Walgreens.
A new Walgreens study analyzing relative medication adherence of patients filling 90-day supplies of maintenance medications using retail and mail order channels over a one-year period concluded that patients who fill prescriptions via retail have as high or slightly higher adherence levels than those utilizing mail (77 percent vs. 76 percent). The study, “Medication Adherence for 90-Day Quantities of Medication Dispensed Through Retail and Mail Order Pharmacies,” was recently released in the November issue of The American Journal of Managed Care.
This reflects other studies from CVS Caremark, Express Scripts, Kaiser, and BCBSNC. (Although sometimes it shows mail order as better and sometimes retail.)
Of course, the data is slightly different in either case, but the general consensus is the same. So, the question is what’s next. How should you compare the two channels?
- Generic fill rate
- Overall health literacy and health outcomes
- Patient experience / satisfaction
- Payer cost
- Cost to fill
This issue won’t go away so it’s going to be important to continue to find ways to compare the channels and find populations that are similar for comparison or remove the bias.
