 This scoping review examined the factors influencing the design and implementation of health-related fiscal measures in low- and middle-income countries—LIMICS—in order to understand why and how they are being implemented. The study found that the interplay between factors such as localized health and economic evidence, policy championing, interministerial support, and global or regional momentum had the greatest influence on the success of fiscal measures. Additionally, the study found that negative framing and retaliation by industry, vested interests, and governmental policy disjunction can impede the successful implementation of fiscal measures.
