However, existing literature argues that this approach towards evaluating GHIs can inadvertently result in overlooking the impact of social determinants on a disease, as implementers and evaluators are less likely to tackle the complexity of a disease within the larger social, political, cultural, and environmental system. Even if a GHI is effectively evaluated– perhaps showing a decrease in disease prevalence– the challenge remains of comprehensively analyzing the long-term impacts of the GHI by addressing the root social, political, or environmental causes of the disease. Accordingly, existing debates suggest that GHIs should be less concerned with the eradication of specific diseases, and should instead focus primarily on factors– such as basic living conditions, sanitation, and access to nutritious food– that are essential to delivering a sustainable heath program.[11]
