Diabetes self-management in three different income settings: Cross-learning of barriers and opportunities.

The burden of type 2 diabetes is increasing rapidly, not least in Sub-Saharan Africa, and disadvantaged populations are disproportionally affected. Self-management is a key strategy for people at risk of or with type 2 diabetes, but implementation is a challenge. The objective of this study is to assess the determinants of self-management from an implementation perspective in three settings: two rural districts in Uganda, an urban township in South Africa, and socio-economically disadvantaged suburbs in Sweden. Data collection followed an exploratory multiple-case study design, integrating data from interviews, focus group discussions, and observations. Data collection and analysis were guided by a contextualized version of a transdisciplinary framework for self-management. Findings indicate that people at risk of or with type 2 diabetes are aware of major self-management strategies, but fail to integrate these into their daily lives. Depending on the setting, opportunities to facilitate implementation of self-management include: improving patient-provider interaction, improving health service delivery, and encouraging community initiatives supporting self-management. Modification of the physical environment (e.g. accessibility to healthy food) and the socio-cultural environment (i.e. norms, values, attitudes, and social support) may have an important influence on people's lifestyle. Regarding the study methodology, we learned that this innovative approach can lead to a comprehensive analysis of self-management determinants across different settings. An important barrier was the difficult contextualization of concepts like perceived autonomy and self-efficacy. Intervention studies are needed to confirm whether the pathways suggested by this study are valid and to test the proposed opportunities for change.

Introduction

Non-communicable diseases (NCD) are strong contributors to poverty and inequity within and across countries, disproportionately affecting people of low socioeconomic status [1]. A recent series of articles in the Lancet launched a strong call for action against the burden of NCDs [2], directly in line with Sustainable Development Goal (SDG) 3·4 to reduce premature NCD mortality and indirectly in line with SDGs 1, 2, 4, 5, and 10 [1]. Type 2 diabetes (T2D) is a major contributor to the NCD burden. Similar to other NCDs, the global prevalence of diabetes in adults is increasing and is estimated to grow from 8·8% in 2015 to 10·4% in 2040 [3], with Sub-Saharan Africa contributing the largest share of this growth [3]. In high income countries (HICs), socio-economically disadvantaged populations and immigrants are disproportionately affected [4].

Self-management is one of the key elements for adequate prevention and treatment of T2D and other NCDs [5]. It improves care processes and health outcomes, for instance through improved treatment adherence and adaptation of treatment to a person’s situation [5,6]. Self-management means that individuals play an active role in managing their condition. This implies that they engage in decision-making, adopting and adapting strategies to improve their health status regarding that particular condition [7]. It also suggests an engagement in supportive partnerships with other people, such as family, friends, health providers, community members, and peers [7]. To realize the latter, individuals need to adopt a pro-active mind-set, skills, and knowledge. Beyond the individuals’ engagement, this requires the “right” conditions with regards to the health system, the socio-cultural and physical environment, and their family and friends, also categorized as self-management support [8].

Adopting self-management remains a challenge for people living with T2D in both HICs [9] and low and middle income countries (LMICs)[10]. One of the reasons is that it requires an approach tailored to a particular population and context [11]. This requires information on the context-specific determinants and status of self-management, and on the components of self-management support.

The determinants of self-management are usually assessed within the comprehensive package of care for chronic diseases using the chronic care model or a modified version [12]. These models do not adequately include the individual behavioral mechanisms that play an essential role in self-management. Behavior change models, on the other hand, focus on the individual pathways of behavior, but do not include the specific actors and health system elements. In this study, we use a framework that connects–from a perspective of chronic conditions–essential mechanisms of behavior change, a comprehensive analysis of relevant actors, the proximal environment including the community, and the health care environment.

This study aims at assessing determinants of self-management using the proposed framework in three different settings–rural Uganda, an urban township in South Africa, and socioeconomically disadvantaged suburbs with a predominant immigrant population in Sweden. Furthermore, this study aims at identifying opportunities to improve self-management through learning from these different contexts.

The selected settings offer a potential for reciprocal learning because of their contextual characteristics, such as: income level, role of the community, quality of health care, and experience with other chronic diseases (e.g. HIV/TB in South Africa & Uganda) [13]. Examples of questions for cross-lessons based upon those contextual specifics are: which successful complementing self-management support activities emerge from an under-resourced health system setting (lessons from Uganda)? How can community-based initiatives strengthen self-management (lessons from South Africa and Uganda)? How can facility-based care for prevention and control contribute to self-management of vulnerable groups (lessons from Sweden)?

The study is part of the formative phase of the SMART2D project: “A person-centred approach to Self-Management And Reciprocal learning for the prevention and management of Type 2 Diabetes”. The SMART2D project was funded by the European Union (Horizon 2020), and aims to improve self-management for people at risk of or living with T2D [14]. The development and application of the framework has informed the selection and implementation of self-management strategies in each study site.

Methods

The SMART2D study aims for cross-contextual reciprocal learning in three cycles [13]. The studies in this paper describe the first learning cycle which had three steps. The first step was to build a conceptual framework that fosters a common understanding in the three settings throughout the SMART2D project. In a second step, this common framework was translated concurrently into a generic topic guide and site-specific focus group and interview guides (S1 and S2 Appendix). Site-specific data collection (focus groups, interviews, and observations) was carried out by each of the country teams and preliminary data-analysis was conducted. In a third step, each of the sites populated the themes of the generic topic guide that were applicable to their specific site, based on the data collected in the previous step and additional secondary data (i.e. national statistics, findings from other studies, and project documents). This data was synthesized in a table with cross-cutting themes and a core team assessed commonalities and differences in self-management and its influencing factors which forms the subject of this paper.

Development of a transdisciplinary framework and a topic guide

A common framework was developed to guide site-specific data collection and to develop a generic topic guide. The development of this transdisciplinary self-management framework (hereafter referred to as the “SMART2D framework”) followed an iterative process with inputs from the literature and from researchers from different disciplines during consortium meetings and workshops.

The first step in the development of this framework was a critical review of the literature [15]. We sought to identify the most significant elements (including systems, actors, the environment, the individual) that determine self-management in people living with T2D. In particular, we were looking for studies presenting novel theories and conceptual frameworks. Only theories that were based on empirical evidence were considered, although, no formal quality assessment was done. Studies were identified through the use of search engines like Google scholar and Pubmed, using search terms identified through brainstorming sessions with the research team. Search terms included keywords like: “self-management”, “health systems”, “chronic conditions”, “non-communicable diseases”, “models”, “frameworks”, etc. Search terms were iteratively added and refined with input from collaborating researchers and the identified literature (pearl-harvesting). The search process also included: browsing, “consulting peer experts,” “Snowball” methods such as pursuing references of references, and electronic citation tracking which are known to be powerful for identifying high quality sources in obscure locations [16]. For complex and heterogeneous evidence (such as those undertaken for management and policymaking questions) formal protocol-driven search strategies may fail to identify important evidence, while informal approaches such as the ones used in this search process can substantially increase the yield and efficiency of search efforts [16]. Search results were sorted by relevance and studies were selected based on their potential conceptual contribution.

From the selected studies, we extracted elements or theories that determine self-management and are relevant for T2D. In particular, we focused on mechanisms that explain the individuals’ behavior but are related to their environment or health system. The retrieved elements and theories were discussed in a core research team consisting of the following researchers: a behavioral expert (PA), health systems experts (JVO, JDM, JA, MD), an endocrinologist (CGÖ), and researchers with site-specific expertise from Uganda (RWM), South Africa (PD) and Sweden (HMA). Selected theories and elements were brought together in an initial framework describing the determinants and mechanisms of self-management, which was then presented to the SMART2D consortium. Discussions led to modifications and the present framework is the end result of this process. Theories were selected based on their relevance to self-management among people with chronic conditions (from a multidisciplinary perspective), and relevance to the implementation of self-management. Through the combination of perspectives from different disciplines, this framework brings about a new way of looking at how self-management works beyond the traditional perspective of each of those disciplines. For example: health systems thinking, is connected to individual behavior through individual behavioral mediators.

The initial framework was presented to the country research teams of the consortium during a workshop (that all together comprised 21 members) to discuss the relevance and usability of the framework in each of the study contexts. The discussions involved brainstorming on the role of context-specific factors (i.e. actors, community structures, platforms, partners and strategies associated with self-management). Further development and refinement of the framework continued through a series of workshops and conference calls facilitated by JDM and JVO, held separately for each of the three country research teams until a final version was approved.

The framework integrates behavioral change theories with mediation through latent variables [17], chronic care models [18,19], health systems theory [20], and the influence of the proximal environment to a common perspective that “transcends” the initial perspective of each of the specific disciplines.

The framework is based on the idea that self-management behavior results from a continuous and reciprocal interaction between the individual and the individual’s proximal environment which includes the health system, a socio-cultural component and a physical component.

As such, the framework integrates actors and systems that are considered to play a determining role in self-management (Fig 1; left side; “configuration of actors and systems”). The individual at risk of, or living with T2D has a central role in this configuration of actors and systems and is closely connected to their family and friends. As presented by the innovative care for chronic conditions framework, the individual belongs to an actors’ triad with community health actors and health providers [19]. Each of those actors interact with the health system, the physical environment, and the socio-cultural environment.

Fig 1

The SMART2D self-management framework presenting the different elements that determine self-management.

Legend: Zooming in on the individual reveals mediating factors (in green oval shapes), self-management skills (in the pentagon), and self-management tasks (at the core).

When focusing on the individual (Fig 1; right side) the framework distinguishes three groups of individual or intrapersonal factors: mediating factors at the outer circle, self-management skills in the pentagon, and self-management tasks at the core. The reason to distinguish among these factors is that they have a different function in the implementation of self-management.

The four core self-management tasks (medical management, emotional management, role management, and lifestyle management) positioned at the core of the framework represent self-management behavior and were adopted from Corbin and Strauss [21]. Corbin and Strauss identified three sets of tasks through a qualitative study on the work of people with chronic conditions. What we call lifestyle management in our framework is part of medical management in their classification. Adequate execution of these core self-management tasks results in self-management behavior, requires the five self-management skills, and is facilitated by the five mediators. From an implementation perspective, these tasks should be kept in mind as an end goal, but improvement of these tasks ideally takes place through interventions that address the individual mediators. The five self-management skills were introduced by Lorig and Holman (decision-making, resource utilization, taking action, problem solving, and forming partnerships)[7]. Adoption of these skills is required for the adequate execution of the specific self-management tasks, depends primarily on the initiative of the individual, and is facilitated by the five mediators. Therefore, from an implementation perspective, the adoption of the skills ideally happens through addressing these mediators. Finally, these mediators link the individual’s self-management skills and tasks with their interactions with their proximal environment (Fig 1; “configuration of actors and systems”), which implies that these mediators strongly depend on the environment. Appropriate implementation of self-management should therefore create an environment that fosters change through addressing these mediators when targeting self-management skills or tasks. The five mediators include perceived autonomy, perceived relatedness, and self-efficacy (Box 1), which are identified by Ryan and Deci’s self-determination theory as the three basic psychological needs that foster high quality forms of motivation and engagement, and hence play an important role in the adoption of healthy behavior [17]. Illness representation as defined by Leventhal corresponds to the individual’s understanding of T2D through personal experience, socio-cultural information, and healthcare interactions [22,23]. Learning of strategies refers to acquiring knowledge and understanding of self-management strategies and skills through thought, own experience, and perception (Box 1).

Box 1. Definitions of the individual mediators of self-management.

Perceived autonomy corresponds to the individual regulating his/her behavior with the experience of choice and reflective self-endorsement, while experiencing external pressure to act in a certain way would make her/him feel less autonomous [17].

Perceived relatedness corresponds to the need of feeling connected to and cared about by others [17].

Self-efficacy was initially defined by Bandura as “people's beliefs about their capabilities to produce designated levels of performance that exercise influence over events that affect their lives”[24]. Self-determination theory uses the term perceived competence, but the concept corresponds to Bandura’s self-efficacy [17].

Illness representation can trigger actions to reduce health risk and thus change the individual’s behavior, based on the model developed by Leventhal [22]. This model proposes five core elements: (1) identity refers to the individual’s awareness of signs and symptoms of the disease; (2) cause refers to the individual’s idea of the cause of the condition; (3) timeline refers to how long the condition might last according to the individual; (4) consequences refers to the individual’s ideas about the potential consequences of the condition on her/his life; and (5) control corresponds to whether the condition can be cured or kept under control and the degree to which the individual can take part in this [22].

Learning of self-management strategies includes both the acquiring of knowledge and the development of skills. The learning process corresponds to active learning which occurs when a person takes control of his/her own learning experience. This active learning process can happen through cognitivism (internal processing of information), or constructivism (new information is linked to prior knowledge, leading to a subjective mental construct). In particular, we want to stress the value of social constructivism in self-management: learning takes place because of the interaction with others (e.g. peers, community members, relatives, etc.)[25].

Translation of the SMART2D framework to a topic guide

The constructs presented in the framework were translated into a generic topic guide (S2 Appendix). This translation process was done by a cross-site coordination team comprising of a behavioral scientist (PA, facilitating intervention development) and three health systems researchers (JVO & JDM facilitating cross-country lessons and MD facilitating conceptualization and implementation); and country teams lead by RWM, PD & HMA in Uganda, South Africa, and Sweden respectively. The topic guide covered information related to self-management support to be sourced from site-specific primary data collected through focus group discussions, individual interviews, observations, and other relevant secondary data.

Regarding the individual, the guide focuses on the characteristics of the studied populations and individual mediators. Regarding family and friends, the guide explores how they support the individual. Regarding the health providers, the focus is on interpersonal quality of care of public primary care providers. Regarding the community health actors, the focus is on identifying relevant community initiatives and their link with health providers. Regarding the health system, the focus is on aspects of service delivery (i.e. accessibility, quality of care, continuity of care, type of care). Regarding the socio-cultural and physical environment, the focus is on elements that influence physical activity and healthy diets.

Data collection

Concurrent data collection using the site-specific focus group and interview guides (S1 Appendix) and the generic topic guide (S2 Appendix) was informed by the SMART2D framework presented in the first paragraph of this section. In-depth interviews, FGDs and observations were conducted in each site from March to August 2015 and preliminary data analysis was done side-by-side to inform the topic guide. Table 1 provides a summary of participants’ details, recruitment, and data collection of the primary data in each site (also published or submitted elsewhere as indicated in the table). Concurrently, from March to December 2015, data were collected using the generic topic guide and following an exploratory and multiple case study design, which allows exploring self-management within its real-life context through the concurrent use of different sources of information and data collection methods [26]. Data pertaining to three cases were collected: 1) an urban township in Cape Town, South Africa; 2) socioeconomically disadvantaged suburbs in Stockholm County, Sweden; 3) a rural area comprising of Iganga and Mayuge district, Uganda. All processes described henceforth refer to data collected through the generic topic guide.

Data-analysis

Data-analysis was informed by the framework method which allowed exploring data systematically and in-depth, while maintaining an effective and transparent audit trail and facilitating collaboration among our multidisciplinary team [32]. The analysis followed four steps: (1) Theoretical coding of the raw site-specific data by each country research team: Site-specific analysis of the data sets was conducted by multidisciplinary teams of 5–7 members in the respective sites who comprised: health systems researchers including medical doctors and nutritionists, public health scientists, intervention and implementation research experts, and anthropologists. Three research team members in each of the sites coded the data using NVivo software version 11 in Sweden and Ti software version 7.0 in South Africa and Uganda. Categorizing of similar codes into themes, assessment and refinement of the final themes and sub-themes was collectively done by the respective site teams. Some of the site-specific data is published elsewhere [28,30] and others are under review; (2) For the purpose of cross-site data synthesis and this paper, the site-specific data were assigned to a set of themes predefined and organized based on the structure in the cross-site topic guide. Data was triangulated from different sources including interviews, observations and literature, resulting in a country-case description; (3) Data from three sites was then systematically charted using a framework matrix (see Table 2 of the results section) following the main topics of the framework: the individual, the individual mediators, family and friends, the health providers, the community health actors, the health system, the social environment, and the physical environment; (4) The elements identified in the previous steps were classified as ‘differences’ or ‘similarities’ between sites. This classification was based on the element’s presence and estimated contribution to self-management in a particular context. An element meeting those two criteria in one context and not in another context was classified as a difference. If it met both criteria in two different contexts, it was classified as a similarity. Two experts (JDM, JVO) evaluated each element based on those two criteria. In case of disagreement, the element was discussed with a third expert (MD). Results were then shared with the specific country teams and in case of disagreement, the elements were discussed a third time.

Results

Results of the site-specific analysis

Table 2 presents the results by site (vertically) and by main- and sub-topics (horizontally) following the structure of the topic guide.

Cross-comparison

The sites share characteristics in terms of awareness of risks, knowledge about self-management strategies, perceived relatedness, and barriers to implementing these strategies such as a lack of perceived autonomy and self-efficacy. Quality of interaction between providers and people at risk of T2D (i.e. interpersonal quality of care) has room for improvement in the three sites. Most obvious gaps are the lack of a tailored approach and the lack of patient involvement. Participants across the three settings mention failing to implement self-management in their daily routines and perceive a need for more tailored self-management education. The sites share similarities in determinants related to the physical environment (e.g. perceived barriers to physical activity or a healthy diet).

The most noticeable differences across sites relate to structural quality of health service delivery (i.e. accessibility, technical quality of care, continuity of care) and the presence of community initiatives. Quality of health service delivery is very high at the Swedish site, meets essential standards at the South African site, and is poor at the Ugandan site. Presence of self-management-related community initiatives for T2D is high at the South African site, limited at the Swedish site, and absent at the Ugandan site. The ways that people perceive the socio-cultural environment (attitudes, norms, and values) as influential on their lifestyle can be very similar (e.g. limited to no stigmatization of people living with T2D) or very different across sites (e.g. obesity as a sign of wealth in South Africa compared to Sweden).

Table 3 presents the main differences and similarities across sites in more detail per main topic of the topic guide.

Discussion

To our knowledge, this is the first study to explore self-management determinants of T2D among disadvantaged populations in three different settings through the use of a common guiding framework. Earlier studies on disadvantaged populations confirm the influence of psychological factors (e.g. knowledge, beliefs, behavioral skills, etc.)[33] and the individual’s socio-cultural context, including social support networks [34,35], and motivational support from health care providers [36]. However, those studies have not compared different contexts and had a narrow focus on a specific set of elements. Our data cover a comprehensive set of elements that play a role in the implementation of self-management including the individual and their family, health- and community actors, the health system, and the proximal environment. The study links these elements with self-management behavior through individual mediators.

The most noticeable differences across the sites relate to structural quality of health service delivery and the presence of community initiatives. The health system in Uganda is characterized by inadequate basic supplies, shortage of qualified staff, and lack of guidelines, whereas in South Africa, essential diabetes care including secondary prevention is accessible and free at primary level. In Sweden, primary care is more advanced involving multidisciplinary teams, referral systems and electronic medical records, but is primarily facility based and has limited activities focusing on prevention. These differences are linked to the macro-economic status of the country and the historical development of the respective health systems. In SMART2D, we used these inherent differences in the choice of our sites to inform the development of a contextualized self-management support intervention and to learn from each other during this process. The role of the community in diabetes related health promotion and prevention and the linkage between community and the health system is stronger in South Africa than in the other two settings. We identified several elements playing a role in self-management related to people’s proximal environment, mostly relating to lifestyle behavior. Similar to other studies, this demonstrates the importance of the physical and socio-cultural environment on lifestyle behavior [37,38] Social and cultural factors influencing people’s lifestyle were more similar between Uganda and South Africa and different from the Swedish setting.

Across the three study sites, participants are aware of the risks of T2D and recommended self-management practices. However, as reported by other studies, integrating those practices into their daily life is challenging [28,39]. Our data identify multiple interrelated factors that may explain this limited integration. Study participants across all three sites share low levels of perceived autonomy and self-efficacy which could be partially explained by patient-provider interactions with limited patient involvement, low autonomy support of patients, and a lack of tailored education. In all sites, participants reported receiving psychological support from friends or family, suggesting perceived relatedness.

This lack of self-efficacy and perceived autonomy may hinder implementation of self-management even if the structural quality of the provided care is excellent as is the case in Sweden (see below). Addressing the lack of structural quality in, for example, the Ugandan setting may therefore not lead to the desired improvement of self-management if such an intervention does not address the reported low self-efficacy and low perceived autonomy among people living with T2D. Similarly, the reported awareness of major self-management strategies suggests no need to increase self-management education, but rather to reconsider the way education is being implemented, i.e. based on active learning and with more attention for mediators like self-efficacy, perceived autonomy, and while addressing misconceptions with regards to traditional beliefs.

Methodological considerations

To our knowledge, the transdisciplinary framework presented in this study was the first to combine a comprehensive set of elements that determine self-management (actors, the health system, the environment, etc.) with individual mediators from a behavior change perspective. This approach allows for an explanation of how external elements (e.g. the health system, the proximal environment) influence individual mediators and ultimately self-management behavior within a real-life context and addresses limitations in the understanding of self-management implementation. The strength of the proposed framework lies in the use of generic pathways that link the proximal environment and the health system with the individual’s behavior or self-management for different settings enabling cross-comparison. This contributes to a better understanding of self-management, beyond the traditional explanations from a health systems perspective (e.g. a lack of resources) or a population perspective (e.g. low socio-economic status). Consequently, this framework also identifies other and eventually more feasible solutions beyond the traditional structural changes (e.g. improve the infrastructure of the health system). Bronfenbrenner’s socio-ecological framework, which has been widely used in public health, also addresses the determinants of health at different levels. However, it does not account for the pathways explaining the individual’s behavior [40]. Bronfenbrenner attempts to explain this at cognitive level through ‘force characteristics’, nevertheless those characteristics seem to be a collection of personal traits and cognitive concepts (e.g. temperament, self-efficacy, etc.) without a clear link between the environment and one’s behavior [41]. Brown et al. also linked individual and external factors influencing self-management, but mainly focused on elements related to the individual’s socioeconomic position, ignoring individual psychological mediators [42]. Berkman et al. highlighted the importance of psychological pathways by linking social integration with health, but their study discussed health in general and was not focused on self-management or chronic diseases [43].

The study methods facilitated cross-learning among different sites through the use of a common conceptual framework and the framework method. The active involvement of the local research teams in the translation of the framework to the data collection guide facilitated contextualization. The framework was comprehensive and yielded rich data on the determinants of self-management in the respective contexts, but translation of the framework concepts to data collection tools was difficult and resource intensive. The process required several online meetings and workshops with the implementation teams from the respective study sites. Translation of the framework required a focus on certain elements at the cost of others, based on what the teams estimated as relevant for their context and what was feasible in terms of data collection.

Application of the framework for data collection was equally challenging for the implementation teams. They perceived the topic guide as very broad, theory-driven, and difficult to adapt to the three local contexts. Abstract concepts like the psychological mediators (e.g. perceived autonomy, self-efficacy) were difficult to translate and measure, which could explain why data related to some of these theoretical constructs is sparse for all study sites. This sparseness of data hindered the full application of the framework and as a consequence, the understanding of self-management. Actual data collection was also hindered by factors like limited human resources, a lack of security for data collection teams in some study areas, particularly in South Africa, and delays in mobilizing community stakeholders and healthcare providers, particularly in Sweden.

The major part of our findings resulted from a triangulation of interviews with different participants or other sources of information (e.g. observations, evidence from the literature), which contributed to the credibility of the results. Findings relate to populations which are disadvantaged in similar ways (socio-economically, educationally, type of housing, etc.), but are living in three different settings. Compiling evidence based on data from three different sites contributes to the transferability regarding disadvantaged populations of similar LMICs in Sub-Saharan Africa, and most likely also in HICs.

Cross-comparison of the different sites led to useful insights on how different environments can contribute to self-management through similar pathways. As illustrated before: addressing environmental or health system related shortcomings, while ignoring those mediators, may therefore not lead to the desired effect. The authors acknowledge that the sparseness of data regarding those mediators has hindered cross-comparison. More precise information regarding those mediators may therefore lead to a better understanding of how different contexts or environments and related interventions influence self-management.

Conclusion

The implementation of self-management relates to a complex interplay between the individual, the socio-cultural and physical environment, the health system, and related actors. Implementing self-management in a particular context will benefit from an overarching framework contextualized through a situation analysis. Essential is that such a framework not only identifies the necessary self-management support interventions, but also how these interventions need to be implemented. This can be obtained through consideration of the pathways linking the individual’s behavior with its proximal environment.

This study uses a transdisciplinary framework to identify major gaps and opportunities to guide the implementation of self-management support in low-resourced or socially disadvantaged areas and populations compiling evidence from three different settings.

Findings indicate that while the studied populations are aware of what self-management for T2D entails, the integration in their daily life is difficult. Despite being in completely different settings, individual mediators and perceptions of the physical (built) environment determining self-management are similar in the three disadvantaged populations, while health systems determinants and community support for self-management largely differ among sites. Depending on the setting, opportunities to facilitate implementation of self-management include: making patient-provider interactions more person-centered, improving access to essential primary care, and encouraging community initiatives supporting self-management. The individual’s physical environment (e.g. accessibility of healthy food) and socio-cultural environment (i.e. norms, values, and social support) play an important role in people’s lifestyle and offer opportunities for change.

The SMART2D self-management framework was developed based on literature reviews and expert consultations, and applied in this study to inform data collection, analysis and interpretation. However, to assess the internal validity and interconnections between different elements, quantitative research is needed. The findings of the present study set a point of departure for research that seeks to understand the pathways for implementation of self-management support interventions. The identified gaps and opportunities can be addressed in field trials focusing on the development and implementation aspects of self-management interventions. The findings from this study may be applicable to disadvantaged populations in similar sub-Saharan LMICs and HICs with vulnerable populations.
