Communication of Medication Nonmedical Switching Policies and Procedures by Insurance Companies: Results of an...

Nonmedical switching is defined as a change in a stable patient's prescribed medication to a clinically distinct, nongeneric alternative for reasons other than lack of clinical response, adverse effects, or poor adherence. Nonmedical switching often results from formulary changes implemented by insurers to lower medication costs. We sought to survey randomly sampled physicians to elicit their opinions regarding insurers' communication about nonmedical switching.

We performed an online, cross-sectional survey of licensed, practicing physicians who were >2 years but <30 years out of residency and/or fellowship, who practiced in an internal medicine, family medicine, or specialist setting, spent ≥10% of their work time providing direct patient care, and had received at least 1 request for a nonmedical switch for ≥1 patient in the prior 12 months. The survey was fielded from November to December 2018. We report weighted percent responses categorized from 5- or 7-point Likert scale questions.

E-mail invitations were sent to 13,117 randomly sampled physicians, and 1818 opened the e-mail and followed the embedded survey link to participate. Of these, 1010 total physicians (55.5%), 606 primary care and 404 specialists, who treated patients experiencing nonmedical switching in the prior 12 months completed the survey. A few physicians were notified about nonmedical switches by insurers; more frequently physicians learned about them from pharmacies serving their patients. Notification frequently occurred at or after a refill came due. Notification via electronic medical record or insurer letter was less frequent. Few thought that insurers clearly communicated information about alternative medications when a nonmedical switch was required, and most disagreed that insurers provided clear procedures, timelines, and methods to track challenges. Nearly all agreed that insurers should provide supporting documentation or rationale for nonmedical switches and specifics on alternatives. Respondents overwhelmingly agreed that steps to improve communication and physicians' and patients' ability to navigate nonmedical switches or challenge procedures should be implemented.

This survey of primary care and speciality physicians suggests that physicians believe that insurers' current level of communication regarding nonmedical switching is suboptimal. Respondents suggested that insurers did not optimally communicate information about alternative medications when a nonmedical switch was required and did not provide clear procedures, timelines, and methods to track challenges. A preponderance of physicians agreed that steps to improve physician-insurer communication to aid in the navigation of nonmedical switch and to challenge procedures should be implemented. If not addressed, these identified nonmedical switch communication issues may have a negative effect on achieving the quadruple aim of enhancing patient experience, improving population health, reducing costs, and improving the work life of health care practitioners and their staff.
