Applicability of the current hypertension guidelines in Latin America

Recent research has focused on the development of evidence-based guidelines that are intended to regulate the conduct of physicians in the diagnosis and control of hypertension, with the goal of achieving greater effectiveness and equity at the lowest possible cost. In Latin America, guidelines are available for the management of hypertension at three levels: national, regional and international. The national and regional Latin American and Caribbean (LAC) guidelines are in fact adaptations of the international guidelines. The potential benefit of applying guidelines developed in other regions to local healthcare decision making is that it will enable decision makers to take advantage of existing analyses and transfer or adapt them to their local contexts. However, this adaptation precludes the assessment of their generalizability and potential transferability. In addition, this region is characterized by wide socioeconomic differences between its inhabitants, both among and within nations. Therefore, new guidelines for the LAC region must include recommendations that are common to all hypertensive patients in the region. Moreover, we advocate the inclusion of a specific section that makes comprehensive recommendations and provides strategies for implementation according to the socioeconomic conditions of particular groups. In addition to developing guidelines that are truly applicable to the LAC region, it seems sensible to consider information that is specific to this region. Furthermore, developing evidence-based guidelines is not enough to affect positively the burden of disease caused by hypertension. Therefore, professional programs are required for the implementation of such guidelines as well as the auditing of their results. Achieving these ambitious goals will require collaborative efforts by many groups including policymakers, international organizations, healthcare providers, universities and society.
