RESUMO
In Uzbekistan, NCDs, including cardiovascular diseases, cancer, and diabetes, accounted for over 80% of mortality in 2019. In 2021, national stakeholders, in conjunction with the World Health Organization, identified brief interventions (BIs) to implement in primary health care settings to change unhealthy behaviors and reduce the burden of NCDs in the country. BIs consist of a validated set of questions to identify and measure NCD behavioral risk factors and a short conversation with patients/clients about their behavior, as well as the provision of a referral opportunity for further in-depth counseling or treatment if needed. We used a multimethod approach of document review, participatory workshops, and key informant interviews to describe how BIs were designed and implemented in Uzbekistan and generated a theory of change for its large-scale implementation. BIs in Uzbekistan targeted 4 risk factors (alcohol use, tobacco use, unhealthy diet, and physical inactivity) and entailed training clinicians on how to conduct behavioral change counseling using the 5As and 5Rs toolkit, conducting supportive supervision, and using feedback to improve service delivery. The program was collaboratively designed by multiple stakeholders across sectors, including the Ministries of Health, Higher Education, Science, and Innovations, with buy-in from key political leaders. The potential impact of the program (i.e., reducing the incidence of NCDs) was mediated by several intermediate and implementation outcomes at the individual, primary care, and community levels operating along multiple pathways. Significant health system challenges remain to the program, such as limited human resources, lack of incentives for clinicians, outdated systems and data collection processes for performance monitoring, and coordination among different relevant sectors. These and other challenges will need to be addressed to ensure the effective large-scale implementation of BIs in Uzbekistan and similar LMICs.
RESUMO
Noncommunicable diseases (NCDs), including cardiovascular diseases, cancer, and diabetes, account for over 80% of mortality in Uzbekistan and Kyrgyzstan in 2019, and unhealthy dietary behaviors are a major risk factor for NCDs in both countries. In 2021, national stakeholders, in consultation with the World Health Organization, identified school nutrition policies (SNPs) as a major approach to reducing the burden of NCDs in both countries. The SNPs included interventions implemented through a multistakeholder and multisectoral arrangement that aimed to improve the health and nutrition status of children and young people by providing healthy food/beverages and restricting unhealthy foods or beverages in schools. We used a multimethod approach of document review, participatory workshops, and key informant interviews to generate theories of change for the large-scale implementation of SNPs and describe the implementation processes to date, including key implementation and health system challenges, salient implementation strategies, and implementation outcomes in both countries. Multiple pathways for enacting and implementing SNPs successfully were identified. However, significant health system challenges, such as the lack of accountability for contracting and tender processes and coordination among different sectors, continue to hamper the large-scale implementation of these policies in both countries. The pathways, theories, and implementation outcomes identified will facilitate the development of implementation strategies and systematic learning and evaluation around SNPs for NCD prevention and control programs in the Central Asian region and other low- and middle-income countries more broadly.
RESUMO
BACKGROUND: Given the complex determinants of non-communicable diseases (NCDs), and the dynamic policy landscape, researchers and policymakers are exploring the use of systems thinking and complexity science (STCS) in developing effective policies. The aim of this review is to systematically identify and analyse existing applications of STCS-informed methods in NCD prevention policy. METHODS: Systematic scoping review: We searched academic databases (Medline, Scopus, Web of Science, EMBASE) for all publications indexed by 13 October 2020, screening titles, abstracts and full texts and extracting data according to published guidelines. We summarised key data from each study, mapping applications of methods informed by STCS to policy process domains. We conducted a thematic analysis to identify advantages, limitations, barriers and facilitators to using STCS. RESULTS: 4681 papers were screened and 112 papers were included in this review. The most common policy areas were tobacco control, obesity prevention and physical activity promotion. Methods applied included system dynamics modelling, agent-based modelling and concept mapping. Advantages included supporting evidence-informed decision-making; modelling complex systems and addressing multi-sectoral problems. Limitations included the abstraction of reality by STCS methods, despite aims of encompassing greater complexity. Challenges included resource-intensiveness; lack of stakeholder trust in models; and results that were too complex to be comprehensible to stakeholders. Ensuring stakeholder ownership and presenting findings in a user-friendly way facilitated STCS use. CONCLUSION: This review maps the proliferating applications of STCS methods in NCD prevention policy. STCS methods have the potential to generate tailored and dynamic evidence, adding robustness to evidence-informed policymaking, but must be accessible to policy stakeholders and have strong stakeholder ownership to build consensus and change stakeholder perspectives. Evaluations of whether, and under what circumstances, STCS methods lead to more effective policies compared to conventional methods are lacking, and would enable more targeted and constructive use of these methods.
