In healthcare research, the payer perspective refers to the viewpoint and priorities of the entities responsible for paying for healthcare services, such as health insurance companies, government agencies, or employers offering healthcare benefits. This perspective typically focuses on cost containment, efficiency, and the value of healthcare services in terms of outcomes and cost-effectiveness. Payer perspective research aims to understand how payers make decisions about coverage, reimbursement, and utilization management, and how these decisions impact patients, providers, and the healthcare system as a whole. By studying the payer perspective, researchers can identify opportunities for improving healthcare delivery, reducing costs, and enhancing the overall value of healthcare services.
