The shift of health care burden from acute to chronic conditions is strongly linked to lifestyle and behaviour. As a consequence, health services are attempting to develop strategies and interventions that can attend to the complex interactions of social and biological factors that shape both. In this paper we trace one of the most influential incarnations of this 'turn to the complex': the Medical Research Council (MRC) guidance on developing and evaluating complex interventions. Through an analysis of the key publications, and drawing on social scientific approaches to what might constitute complexity in this context, we suggest that such initiatives need to adjust their conceptualisation of 'the complex'. We argue that complexity needs to be understood as a dynamic, ecological system rather than a stable, albeit complicated, arrangement of individual elements. Crucially, in contrast to the experimental logic embedded in the MRC guidance, we question whether the Randomised Controlled Trial (RCT) is the most appropriate method through which to engage with complexity and establish reliable evidence of the effectiveness of complex interventions.

BackgroundDiabetes in pregnancy is common in South Asians, especially those from low-income backgrounds, and leads to short-term morbidity and longer-term metabolic programming in mother and offspring. We sought to understand the multiple influences on behaviour (hence risks to metabolic health) of South Asian mothers and their unborn child, theorise how these influences interact and build over time, and inform the design of culturally congruent, multi-level interventions.MethodsOur sample for this qualitative study was 45 women of Bangladeshi, Indian, Sri Lankan, or Pakistani origin aged 21–45 years with a history of diabetes in pregnancy, recruited from diabetes and antenatal services in two deprived London boroughs. Overall, 17 women shared their experiences of diabetes, pregnancy, and health services in group discussions and 28 women gave individual narrative interviews, facilitated by multilingual researchers, audiotaped, translated, and transcribed. Data were analysed using the constant comparative method, drawing on sociological and narrative theories.ResultsKey storylines (over-arching narratives) recurred across all ethnic groups studied. Short-term storylines depicted the experience of diabetic pregnancy as stressful, difficult to control, and associated with negative symptoms, especially tiredness. Taking exercise and restricting diet often worsened these symptoms and conflicted with advice from relatives and peers. Many women believed that exercise in pregnancy would damage the fetus and drain the mother’s strength, and that eating would be strength-giving for mother and fetus. These short-term storylines were nested within medium-term storylines about family life, especially the cultural, practical, and material constraints of the traditional South Asian wife and mother role and past experiences of illness and healthcare, and within longer-term storylines about genetic, cultural, and material heritage – including migration, acculturation, and family memories of food insecurity. While peer advice was familiar, meaningful, and morally resonant, health education advice from clinicians was usually unfamiliar and devoid of cultural meaning.Conclusions‘Behaviour change’ interventions aimed at preventing and managing diabetes in South Asian women before and during pregnancy are likely to be ineffective if delivered in a socio-cultural vacuum. Individual education should be supplemented with community-level interventions to address the socio-material constraints and cultural frames within which behavioural ‘choices’ are made.

The human microbiome is an important emergent area of cross, multi and transdisciplinary study. The complexity of this topic leads to conflicting narratives and regulatory challenges. It raises questions about the benefits of its commercialisation and drives debates about alternative models for engaging with its publics, patients and other potential beneficiaries. The social sciences and the humanities have begun to explore the microbiome as an object of empirical study and as an opportunity for theoretical innovation. They can play an important role in facilitating the development of research that is socially relevant, that incorporates cultural norms and expectations around microbes and that investigates how social and biological lives intersect. This is a propitious moment to establish lines of collaboration in the study of the microbiome that incorporate the concerns and capabilities of the social sciences and the humanities together with those of the natural sciences and relevant stakeholders outside academia. This paper presents an agenda for the engagement of the social sciences with microbiome research and its implications for public policy and social change. Our methods were informed by existing multidisciplinary science-policy agenda-setting exercises. We recruited 36 academics and stakeholders and asked them to produce a list of important questions about the microbiome that were in need of further social science research. We refined this initial list into an agenda of 32 questions and organised them into eight themes that both complement and extend existing research trajectories. This agenda was further developed through a structured workshop where 21 of our participants refined the agenda and reflected on the challenges and the limitations of the exercise itself. The agenda identifies the need for research that addresses the implications of the human microbiome for human health, public health, public and private sector research and notions of self and identity. It also suggests new lines of research sensitive to the complexity and heterogeneity of human–microbiome relations, and how these intersect with questions of environmental governance, social and spatial inequality and public engagement with science.

Social prescribing (SP) seeks to enhance the role of the voluntary and community sector in addressing patients' complex needs in primary care. Using discourse analysis, this review investigates how SP is framed in the scientific literature and explores its consequences for service delivery. Theory driven searches identified 89 academic articles and grey literature that included both qualitative and quantitative evidence. Across the literature three main discourses were identified. The first one emphasised increasing social inequalities behind escalating health problems and presented SP as a response to the social determinants of health. The second one problematised people's increasing use of health services and depicted SP as a means of enhancing self‐care. The third one stressed the dearth of human and relational dimensions in general practice and claimed that SP could restore personalised care. Discourses circulated unevenly in the scientific literature, conditioned by a wider political rationality which emphasised individual responsibility and framed SP as ‘solution’ to complex and contentious problems. Critically, this contributed to an oversimplification of the realities of the problems being addressed and the delivery of SP. We propose an alternative ‘care‐based’ framing of SP which prioritises (and evaluates) holistic, sustained and accessible practices within strengthened primary care systems.

BackgroundSocial prescribing (SP) involves linking patients in primary care with services provided by the voluntary and community sector. Despite growing interest within NHS primary care, it remains unclear how and under what circumstances SP might contribute to good practice.AimTo define ‘good’ practice in SP by identifying context-specific enablers and tensions. To contribute to the development of an evidence-based framework for theorizing and evaluating SP within primary care.Design and settingRealist review of secondary data from primary care-based SP schemes.MethodWe searched for qualitative and quantitative evidence from academic articles and grey literature following the Realist and Meta-narrative Evidence Syntheses-Evolving Standards (RAMESES). We characterised common SP practices in three settings (general practice, link workers and community sector) using archetypes which ranged from best to worst practice.ResultsA total of 140 studies were included for analysis. We characterised common SP practices in three settings (general practice, link workers and community sector) using archetypes which ranged from best to worst practice. We identified resources influencing the type and potential impact of SP practices and outlined four dimensions in which opportunities for good practice arise: 1) individual characteristics (stakeholder’s buy-in, vocation, knowledge); 2) interpersonal relations (trustful, bidirectional, informed, supportive, transparent and convenient interactions within and across sectors); 3) organisational contingencies (the availability of a predisposed practice culture, leadership, training opportunities, supervision, information governance, resource adequacy and continuity and accessibility of care within organisations); and 4) policy structures (bottom-up and coherent policymaking, stable funding and suitable monitoring strategies). Findings where synthesised in a multi-level, dynamic and usable SP Framework.ConclusionOur realist review and resulting framework revealed that SP is not inherently advantageous. Specific individual, interpersonal, organisational and policy resources are needed to ensure SP best practice in primary care.

Background Falling retention in UK general practice is a well-described problem but there has been little previous research into its underlying causes. Poor psychosocial work conditions may help explain falling workforce morale and early retirement from the profession. Aims To explore the impact upon morale and retirement decisions of changes in psychosocial aspects of UK general practice over the course of a career. Methods Biographical narrative interviewing method (BNIM) was used to obtain and analyse career narratives of 12 London general practitioners (GPs), aged 55–65, half of whom had retired. Findings were theorized using the Job Demands-Control-Support (JDCS) model. Results A spontaneous, consistent theme was evident across all 12 interviews: changes in the psychosocial work environment had contributed to a steady decline in morale. Sequential, multilayered reductions in autonomy were the most commonly cited causes for reduced enthusiasm. Increasing demands in the form of both a rising workload as well as a complaints culture drained energy and morale. The GPs described increasingly fragmented teams and therefore reduced social support for the role. Nonetheless, retirement decisions were not straightforward, provoking complex emotions. Conclusions The combination of increasing demands with reduced autonomy puts practitioners under intense strain, diminishing the satisfaction they derive from their work and affecting retirement decisions. The Job Demands-Control-Support (JDCS) model is an empirically tested model that could be used to inform improved work design in general practice.
