Health plan member experience with point-of-service prescription step therapy

To better understand health plan member experience with point-of-service prescription step-therapy edits and outcomes in terms of drug received.

Self-administered mailed surveys were sent to 1,000 members who experienced a step-therapy edit from September 1, 2002, through January 31, 2003, for proton pump inhibitors or nonsteroidal anti-inflammatory drugs. Based upon these findings, a second survey was conducted by telephone among 617 members who experienced a step-therapy edit from January through April 25, 2003, and who had no subsequent prescription claim for the drug therapy class associated with the edit.

The mailed survey generated a 23% response rate, and the telephone survey generated a 33% response rate. Just over 66% of the mail survey respondents indicated that they contacted their physician directly to try to remedy the situation, while 40% indicated that their pharmacist contacted their physician. Forty-four (44%) percent of members indicated that they received a different medication than was originally prescribed, 15% obtained prior authorization for the brand medication, 11% received no medication, 11% paid full price for the branded medication, 8% got an over-the-counter medication, and 4% received samples from their physician. Approximately 7% sought other means of obtaining coverage (i.e., they used spouse.s insurance) or did not remember the outcome. Member and pharmacy contact with the physician significantly influenced whether the member obtained a medication covered by their health plan (odds ratio [OR] = 6.5; 95% confidence interval [95% CI], 2.76-15.12 and OR = 4.6; 95% CI, 1.96-10.60, respectively). In a separate survey conducted by telephone among a different group of members, insight into reasons why members did not obtain any medication was obtained. Using a closed-ended question, 12% (n = 25) of members indicated receiving no medication. Upon further questioning, however, 32% of those who indicated that they had not received a medication said that they had in fact received a medication to treat their condition some time after the step edit. The second most common reason for not receiving a medication included issues related to cost (i.e., willingness to pay) or affordability (16% and 28%, respectively).

The results of this study suggest that a majority of members receive a medication covered by their health plan subsequent to rejection of a claim for a prescribed drug that is the target of a step-therapy edit. However, there are opportunities for better member and provider communication designed to increase the use of first-line drugs and reduce the number of members paying out-of-pocket or receiving no medication.
