Whole systems approach to diet and healthy weight: a longitudinal process evaluation in East Scotland

AIMS

Obesity contributes to morbidity and early mortality, affecting people of all ages and sociodemographic backgrounds. Despite attempts to address obesity, efforts to date have only had limited success. Adopting a whole systems approach (WSA) may potentially address obesity and emphasise complex inter-relating factors beyond individual choice. This study aimed to assess implementation of WSA to diet and healthy weight in two council areas of Scotland, longitudinally exploring enablers and barriers. One area followed a Leeds Beckett WSA model (LBM) of implementation, while the other used a hybrid model incorporating existing working systems.

METHODS

To assess the process of implementing a WSA, interviews and focus groups were conducted after initiation and 1 year later.

RESULTS

Main enablers included: belief in WSA effectiveness; positive relationships between key personnel; buy-in at community and national levels; funding availability; the working group responsible for coordinating the system development comprising individuals with diverse expertise; good communication; and existing governance structures. Barriers included: insufficient funding; high staff turnover; inadequate training in WSA methodology; engaging all relevant stakeholders and reverting to 'old ways' of non-WSA working. The LBM provided a framework for system setup and generating an action plan.

CONCLUSION

This study provides the first independent longitudinal process evaluation of WSAs that have incorporated Leeds Beckett methodology, and offers insights into how a WSA can be implemented to address diet and healthy weight.

Evaluation of the move to remote delivery of drug and alcohol services during the COVID-19 pandemic: A study protocol

Background:

Substance misuse is a significant global health concern. In the UK, the prevalence of substance misuse has increased over the past decade and the number of alcohol and drug related deaths are increasing. Individuals with substance dependency issues are entitled to access treatment services. However, the COVID-19 pandemic created significant challenges for public services, including drug and alcohol treatment, and resulted in significant service reconfiguration and a shift from in-person to remote delivery. This study aims to evaluate the delivery of drug and alcohol services in a large metropolitan area in Northern England during the COVID-19 pandemic. It aims to understand the impact of service reconfiguration for services, staff and service users, and to use this understanding to inform the future optimised design of services.

Design and methods:

The study has five workstreams within a mixed methods framework: (1) Systematic review of literature; (2) Qualitative process evaluation with service providers (digital timelines, focus groups and interviews); (3) Qualitative process evaluation with service users (interviews, focus groups, text based conversations and case studies); (4) Quantitative outcomes and health economic analysis; and (5) Data synthesis and dissemination.

Expected Impact of the study for Public Health:

The breadth of the study, its novel nature, and the importance of substance misuse as a public health issue, mean that this study will provide valuable findings for those who commission, deliver and use drug and alcohol treatment services nationally and internationally. There will also be important learning for the effective remote delivery of services in sectors beyond drug and alcohol treatment.

Evaluation of a whole system approach to diet and healthy weight in the east of Scotland: Study protocol

Obesity is a global epidemic affecting all age groups, populations and income levels across continents. The causes of obesity are complex and are routed in health behaviours, environmental factors, government policy and the cultural and built environment. Consequently, a Whole System Approach (WSA) which considers the many causes of obesity and shifts the focus away from individuals as points of intervention and puts an emphasis on understanding and improving the system in which people live in is required. This protocol describes a programme of research that will: critically evaluate the evidence for WSAs; assess longitudinally the implementation of a WSA to diet and healthy weight to explore the range of levers (drivers) and opportunities to influence relevant partnerships and interventions to target obesity in East Scotland. The programme consists of four workstreams within a mixed methods framework: 1) Systematic review of reviews of WSAs to diet and healthy weight; 2) Longitudinal qualitative process evaluation of implementing two WSAs in Scotland; 3) Quantitative and Qualitative momentary analysis evaluation of a WSA; and 4) the application of System Dynamics Modelling (SDM) methodology to two council areas in Scotland. A Public Involvement in Research group (PIRg) have informed each stage of the research process. The research programme’s breadth and its novel nature, mean that it will provide valuable findings for the increasing numbers who commission, deliver, support and evaluate WSAs to diet and healthy weight nationally and internationally.
