About this study
Specialty medications often have dispensing restrictions which can be dictated by manufacturer limited distribution strategies, narrow insurance networks, or a combination of both. Unfortunately, this may result in patients being required to use 2 or more pharmacies to fill their prescription medications; this is referred to as multiple pharmacy use (MPU). The investigators' plan is to administer a survey to patients who have been prescribed one or more specialty medications to evaluate the prevalence of MPU in this population as well as to investigate patients' attitudes about MPU and potential factors increasing the likelihood of MPU
Read the detailed description
The investigators will identify patients from participating member sites via a review of prescribing records for specific specialty medications. Patients will be contacted via telephone to explain the purpose and risk of the study. Consented patients will then be asked a series of 11 questions about their attitudes and experience with taking and obtaining their specialty medication(s). Additional demographic and clinical information about patients will be collected via chart review.
