Patient Experience Survey: Protecting Lifelines to Access and Innovation is the fourth installment of the Patient Experience Survey (PES), a research initiative that looks at the lived experiences of more than 5,000 Americans as they navigate their health insurance. The data collected reveal the repercussions of PBM and insurer practices on health care costs, barriers between patients and medicines and risks to future innovative treatments, as well as Americans’ overwhelming support for patient-centered policy solutions that lower out-of-pocket costs and hold insurers and PBMs accountable to patients.
