The objectives for this research are to: 1) understand how payers gather and organize decision resources; 2) identify and rank external influencers in reimbursement decision making; and, 3) explore internal processes for reimbursement decisions. Senior-level decision-makers (n=10) from US payer organizations (n=9) representing 206.1 million member lives were recruited in May 2020 to participate in a web survey (9 topics) and qualitative telephone interview (approximately 20 minutes). Advisers were required to have a high level of knowledge surrounding formulary decision-making, clinical pathways and medical policy development, and manufacturer contracting. Descriptive statistics (e.g. Surveymonkey ranking scores, weighted means, % of mentions) and contextual analysis were used to analyze the results. Subanalyses were conducted by payer archetype (integrated delivery network, pharmacy benefit manager, regional/national managed care organization). Payers use the following information sources most frequently: government organizations (e.g. CDC, NIH) (4.1), research at own institution (3.9), and peer-reviewed journals (3.8). Internally developed HCRU/disease costing analyses most frequently (90%) use data or survey/registry based on health plan data. The most influential organizations to payers are: CMS rules (100%), internal guidelines (100%), and KOL input (90%). Pharmacy and Therapeutics (P&T) committees are frequently comprised of pharmacy directors (100%), medical directors (90%), and independent practicing physicians (80%). A majority (60%) of P&T committees meet quarterly, most often discussing formulary management and drug-use policies (100%). Payers report that newly approved drugs are not frequently reviewed immediately upon approval (70%) and often/always delayed (50%). Only 60% report proactively communicating decisions to provider networks. Variation on decision resource sources, process, and timing exists among US payer archetypes and organizations. While more payers are beginning to rely on analysis from external organizations and their member data, the core focus still remains on gathering and analyzing clinical and safety evidence from literature and consensus-developed guidelines.
