RESUMEN

Introduction: The Brazil has one of the largest public health systems in the world and in the 1980's, Traditional, Complementary and Integrative Medicine were introduced. In 2018, the treatment with ozone became a complementary integrative practice showing several benefits. However, its effectiveness needs to be researched. The objective of this evidence gap map is to describe contributions of Integrative Medicines-Ozone treatment in different clinical conditions, to promote evidence-based practice. Methods: We applied the methodology developed by Latin American and Caribbean Center on Health Sciences Information based on the 3iE evidence gap map. The EMBASE, PubMed and Virtual Health Library databases, using the MeSH and DeCS terms for the treatment with Ozone were used. Results: 26 systematic reviews were characterized, distributed in a matrix containing 6 interventions (parenteral oxygen/ozone gas mixture; parenteral ozonated water; systemic routes; topical application ozonated water; topical oxygen/ozone gas mixture; and topical ozonated oil) and 55 outcomes (cancer, infection, inflammation, pain, quality of life, wound healing and adverse effects). 334 associations between intervention and outcome were observed, emphasizing the parenteral oxygen/ozone gas mixture intervention (192 associations, 57%). Conclusions: The evidence gap map presents an overview of contributions of Ozone treatment in controlling pain, infections, inflammation and wound healing, as well as increasing the quality of life, and it is directed to researchers and health professionals specialized in Ozone treatment. No serious adverse effects were related. Therefore, this treatment may be even more widely known as an integrative treatment, considering its low cost, efficiency and safety. Future studies should adopt economic impact assessments and the organization of health services.

RESUMEN

[ABSTRACT]. Access to information and intercultural approaches in the field of health are essential for the elimination of inequities in health access and care. Intercultural models such as traditional, complementary, and integrative medicine (TCIM) are an important part of health care in most countries and often contribute to expanding access to primary health care. Despite legal recognition and policies to integrate TCIM into health systems, their contribution to health, well-being, and people-centered care to achieve universal health is still underestimated. This article presents the progress (2017-2020) achieved by the Virtual Health Library specialized in the TCIM (VHL TCIM Americas), an initiative created as a tool to reduce the gaps in the production and access to validated information on TCIM. Through collaborative network work, VHL TCIM Americas contributes to the democratization of health, access to verified scientific data, visibility of non-conventional knowledge, strengthening of research capacities, and exchange of experiences for informed decision-making.

[RESUMEN]. El acceso a la información y los abordajes interculturales en el ámbito de la salud son esenciales para la eliminación de inequidades en el acceso a los servicios de salud y la atención sanitaria. Los modelos interculturales, como las medicinas tradicionales, complementarias e integrativas (MTCI) son una parte importante del cuidado de la salud en la mayoría de los países y frecuentemente contribuyen a ampliar el acceso a la atención primaria de salud. A pesar del reconocimiento legal y de la existencia de políticas para la integración de las MTCI en los sistemas de salud, aún se subestima su contribución a la salud, el bienestar y la atención de la salud centrada en las personas para alcanzar la salud universal. En este artículo se presentan los avances (2017-2020) alcanzados por la Biblioteca Virtual en Salud especializada en las MTCI (BVS MTCI Américas), iniciativa creada como herramienta para disminuir las brechas en la producción y el acceso a la información validada sobre las MTCI. Mediante el trabajo colaborativo en red, la BVS MTCI Américas contribuye a la democratización de la salud, el acceso a datos científicos verificados disponibles, la visibilización de conocimientos no convencionales, el fortalecimiento de capacidades de investigación y el intercambio de experiencias para la toma informada de decisiones.

RESUMEN

BACKGROUND: Governments are incentivized to develop and implement health action programs focused on equity to ensure progress with effective strategies or interventions. OBJECTIVE: Identify and synthesize strategies or interventions that facilitate the reduction of health inequalities. METHODS: A systematic search strategy was carried out up until August 2019 in MEDLINE (Ovid), Embase (Elsevier), Cochrane Database of Systematic Reviews, LILACS, Scopus, Scielo and Epistemonikos. In addition, a snowball strategy was used. Literature reviews (LRs) of experimental and quasi-experimental studies were included. The identified interventions and outcomes were categorized based on the recommendation by the Cochrane group in "Effective Practice and Organization of Care". The quality of the included LRs was evaluated using the AMSTAR 2 tool. RESULTS: Four thousand ninety-five articles were identified, of which 97 were included in the synthesis of evidence. Most of the studies included focused on the general population, vulnerable populations and minority populations. The subjects of general health and healthy lifestyles were the most commonly addressed. According to the classification of the type of intervention, the domain covered most was the delivery arrangements, followed by the domain of implementation strategies. The most frequent group of outcomes was the reported outcome in (clinical) patients, followed by social outcomes. CONCLUSION: The strategies that facilitate the reduction of health inequalities must be intersectoral and multidisciplinary in nature, including all sectors of the health system. It is essential to continue generating interventions focused on strengthening health systems in order to achieve adequate universal health coverage, with a process of comprehensive and quality care.
