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.

Use of High-Dose Influenza and Live Attenuated Influenza Vaccines by US Primary Care Physicians.

Background: Several different types of influenza vaccine are licensed for use in adults in the USA including high-dose inactivated influenza vaccine (HD-IIV) and live attenuated influenza vaccine (LAIV). HD-IIV is licensed for use in adults ≥ 65 years, and recommendations for use of LAIV have changed several times in recent years.

Objective: We sought to examine family physicians' (FPs) and general internal medicine physicians' (GIMs) perceptions, knowledge, and practices for use of HD-IIV and LAIV during the 2016-2017 and 2018-2019 influenza seasons.

A randomized, open-label, pragmatic study to assess reliever-triggered inhaled corticosteroid in African American/Black and Hispanic/Latinx adults with asthma: Design and methods of the PREPARE trial.

Asthma prevalence, morbidity, and mortality disproportionately impact African American/Black (AA/B) and Hispanic/Latinx (H/L) communities. Adherence to daily inhaled corticosteroid (ICS), recommended by asthma guidelines in all but the mildest cases of asthma, is generally poor. As-needed ICS has shown promise as a patient-empowering asthma management strategy, but it has not been rigorously studied in AA/B or H/L patients or in a real-world setting.
