Shared Clinical Decision-Making Recommendations for Adult Immunization: What Do Physicians Think?

ABSTRACT

BACKGROUND: In 2019, the Advisory Committee on Immunization Practices (ACIP) incorporated the terminology "shared clinical decision-making" (SDM) into recommendations for two adult vaccines. OBJECTIVE: To assess among general internal medicine physicians (GIMs) and family physicians (FPs) nationally (1) attitudes about and experience with ACIP SDM recommendations, (2) knowledge of insurance reimbursement for vaccines with SDM recommendations, (3) how SDM recommendations are incorporated into vaccine forecasting software, and (4) physician and practice characteristics associated with not knowing how to implement SDM. DESIGN: Survey conducted in October 2019-January 2020 by mail or internet based on preference. PARTICIPANTS: Networks of GIMs and FPs recruited from American College of Physicians (ACP) and American Academy of Family Physicians (AAFP) who practice ≥ 50% in primary care. Post-stratification quota sampling performed to ensure networks similar to ACP and AAFP memberships. MAIN MEASURES: Responses on 4-point Likert scales (attitudes/experiences), true/false options (knowledge), and categorical response options (forecasting). Multivariable modeling with outcome of "not knowing how to implement SDM" conducted. KEY RESULTS: Response rate was 64% (617/968). Most physicians strongly/somewhat agreed SDM requires more time than routine recommendations (90%FP; 95%GIM, p = 0.02) and that they need specific talking points to guide SDM discussions (79%FP; 84%GIM, p = NS). There was both support for SDM recommendations for certain vaccines (81%FP; 75%GIM, p = 0.06) and agreement that SDM creates confusion (64%FP; 76%GIM, p = 0.001). Only 41%FP and 43%GIM knew vaccines recommended for SDM would be covered by most health insurance. Overall, 38% reported SDM recommendations are displayed as "recommended" and 23% that they did not result in any recommendation in forecasting software. In adjusted multivariable models, GIMs [risk ratio 1.44 (1.15-1.81)] and females [1.28 (1.02-1.60)] were significantly associated with not knowing how to implement SDM recommendations CONCLUSIONS: To be successful in a primary care setting, SDM for adult vaccination will require thoughtful implementation with decision-making support for patients and physicians.
