Is the NHS low-calorie diet programme delivered as planned? An observational study examining adherence of intervention delivery to service specification.

Obesity and Type 2 Diabetes Mellitus (T2DM) are chronic conditions with significant personal, societal, and economic impacts. Expanding on existing trial evidence, the NHS piloted a 52-week low-calorie diet programme for T2DM, delivered by private providers using total diet replacement products and behaviour change support. This study aimed to determine the extent to which providers and coaches adhered to the service specification outlined by NHS England. An observational qualitative study was conducted to examine the delivery of both one-to-one and group-based delivery of programme sessions. Observations of 122 sessions across eight programme delivery samples and two service providers were completed. Adherence to the service specification was stronger for those outcomes that were easily measurable, such as weight and blood glucose, while less tangible elements of the specification, such as empowering service users, and person-centred delivery were less consistently observed. One-to-one sessions were more successful in their person-centred delivery, and the skills of the coaches delivering the sessions had a strong impact on adherence to the specification. Overall, the results show that there was variability by provider and delivery mode in the extent to which sessions of the NHS Low-Calorie Diet Programme reflected the intended service specification. In subsequent programmes it is recommended that one-to-one sessions are used, with accompanying peer support, and that providers improve standardised training and quality assurance to ensure specification adherence.

Commercial provider staff experiences of the NHS low calorie diet programme pilot: a qualitative exploration of key barriers and facilitators.

BACKGROUND: The National Health Service Type 2 Diabetes Path to Remission programme in England (known as the NHS Low Calorie Diet programme when piloted) was established to support people living with excess weight and Type 2 Diabetes to lose weight and improve their glycaemic control. A mixed method evaluation was commissioned to provide an enhanced understanding of the long-term cost effectiveness of the pilot programme, its implementation, equity and transferability across broad and diverse populations. This study provided key insights on implementation and equity from the service providers' perspective. METHODS: Thirteen focus groups were conducted with commercial providers of the programme, during the initial pilot rollout. Participants were purposively sampled across all provider organisations and staff roles involved in implementing and delivering the programme. Normalisation Process Theory (NPT) was used to design the topic schedule, with the addition of topics on equity and person-centredness. Data were thematically analysed using NPT constructs with additional inductively created codes. Codes were summarised, and analytical themes generated. RESULTS: The programme was found to fulfil the requirements for normalisation from the providers' perspective. However, barriers were identified in engaging GP practices and receiving sufficient referrals, as well as supporting service users through challenges to remain compliant. There was variation in communication and training between provider sites. Areas for learning and improvement included adapting systems and processes and closing the gap where needs of service users are not fully met. CONCLUSIONS: The evaluation of the pilot programme demonstrated that it was workable when supported by effective primary care engagement, comprehensive training, and effective internal and external communication. However, limitations were identified in relation to programme specifications e.g. eligibility criteria, service specification and local commissioning decisions e.g. pattern of roll out, incentivisation of general practice. A person-centred approach to care is fundamental and should include cultural adaptation(s), and the assessment and signposting to additional support and services where required.

Normalisation and equity of referral to the NHS Low Calorie Diet programme pilot; a qualitative evaluation of the experiences of health care staff.

BACKGROUND: Health and wellbeing can be profoundly impacted by both obesity and type 2 diabetes, while the normalisation and equity of care for people living with these non-communicable diseases remain as challenges for local health systems. The National Health Service Low Calorie Diet programme in England, aims to support people to achieve type 2 diabetes remission, while also reducing health inequalities. We have explored the experiences of health care staff who have made a referral to the LCD programme, while identifying effective and equitable delivery of programme referrals, and their normalisation into routine care. METHODS: Nineteen individual semi-structured interviews were completed health care staff in the first year of the Low Calorie Diet programme. Interviewees were purposively sampled from the ten localities who undertook the Low Calorie Diet programme pilot. Each interview explored a number of topics of interest including communication and training, referrals, equity, and demands on primary care, before being subjected to a thematic analysis. RESULTS: From the data, five core themes were identified: Covid-19 and the demands on primary care, the expertise and knowledge of referrers, patient identification and the referral process, barriers to referrals and who gets referred to the NHS LCD programme. Our findings demonstrate the variation in the real world settings of a national diabetes programme. It highlights the challenge of COVID-19 for health care staff, whereby the increased workload of referrals occurred at a time when capacity was curtailed. We have also identified several barriers to referral and have shown that referrals had not yet been normalised into routine care at the point of data collection. We also raise issues of equity in the referral process, as not all eligible people are informed about the programme. CONCLUSIONS: Referral generation had not yet been consistently normalised into routine care, yet our findings suggest that the LCD programme runs the risk of normalising an inequitable referral process. Inequalities remain a significant challenge, and the adoption of an equitable referral process, normalised at a service delivery level, has the capacity to contribute to the improvement of health inequalities.

Can the delivery of behavioural support be improved in the NHS England Low-Calorie Diet Programme? An observational study of behaviour change techniques.

BACKGROUND: Previous research has illustrated a drift in the fidelity of behaviour change techniques (BCTs) during the design of the pilot NHS England Low-Calorie Diet (NHS-LCD) Programme. This study evaluated a subsequent domain of fidelity, intervention delivery. Two research questions were addressed: (1) To what extent were BCTs delivered with fidelity to providers programme plans? (2) What were the observed barriers and facilitators to delivery? METHODS: A mixed-methods sequential explanatory design was employed. Remote delivery of one-to-one and group-based programmes were observed. A BCT checklist was developed using the BCT Taxonomy v1; BCTs were coded as present, partially delivered, or absent during live sessions. Relational content analysis of field notes identified observed barriers and facilitators to fidelity. RESULTS: Observations of 122 sessions across eight samples and two service providers were completed. Delivery of the complete NHS-LCD was observed for five samples. Fidelity ranged from 33% to 70% across samples and was higher for group-based delivery models (64%) compared with one-to-one models (46%). Barriers and facilitators included alignment with the programme's target behaviours and outcomes, session content, time availability and management, group-based remote delivery, and deviation from the session plan. CONCLUSIONS: Overall, BCTs were delivered with low-to-moderate fidelity. Findings indicate a dilution in fidelity during the delivery of the NHS-LCD and variation in the fidelity of programmes delivered across England. Staff training could provide opportunities to practice the delivery of BCTs. Programme-level changes such as structured activities supported by participant materials and with sufficient allocated time, might improve the delivery of BCTs targeting self-regulation.

Changing the culture: a qualitative study exploring research capacity in local government.

BACKGROUND: Local government has become a key constituent for addressing health inequalities and influencing the health of individuals and communities in England. Lauded as an effective approach to tackle the multiple determinants of health, there are concerns that generating and utilising research evidence to inform decision-making and action is a challenge. This research was conducted in a local authority situated in the north of England and addressed the research question - 'What is the capacity to collaborate and deliver research?'. The study explored the assets that exist to foster a stronger research culture, identified barriers and opportunities for developing research capacity, and how a sustainable research system could be developed to impact on local residents' health and reduce health inequalities. METHODS: This was a qualitative study utilising semi-structured interviews and focus groups. The study used an embedded researcher (ER) who was digitally embedded within the local authority for four months to conduct the data collection. Senior Managers were purposively sampled from across the local authority to take part in interviews. Three focus groups included representation from across the local authority. Framework analysis was conducted to develop the themes which were informed by the Research Capacity Development framework. RESULTS: Tensions between research led decision making and the political and cultural context of local government were identified as a barrier to developing research which addressed health inequalities. Research was not prioritised through an organisational strategy and was led sporadically by research active employees. A recognition across leaders that a culture shift to an organisation which used research evidence to develop policy and commission services was needed. Building relationships and infrastructure across local government, place-based collaborators and academic institutions was required. The embedded researcher approach is one method of developing these relationships. The study identifies the strengths and assets that are embedded in the organisational make-up and the potential areas for development. CONCLUSION: Research leadership is required in local government to create a culture of evidence-based principles and policy. The embedded research model has high utility in gaining depth of information and recognising contextual and local factors which would support research capacity development.

Health-promoting prisons in the female estate: an analysis of prison inspection data.

BACKGROUND: Women in prison have comparatively greater health needs than men, often compounded by structures and policies within the prison system. The notion of a 'health-promoting' prison is a concept which has been put forward to address health inequalities and health deterioration in prisons. It has, however, not been fully discussed in relation to women in prison. The paper aims to distil the learning and evidence in relation to health promotion in female prisons using prison inspection reports of women's prisons in England and Wales. METHODS: Prison inspection reports are one way of ascertaining the contemporary situation in prisons. Prison inspections are often unannounced and use a myriad of methods to draw conclusions around various aspects of prison life. Thirteen prison inspection reports were analysed thematically focusing on health promotion within the institutions. Two analysts conducted the work using NVivo 12. RESULTS: Five core thematic areas were identified during the analysis of the reports. Saliently, a joined-up approach to health promotion was not a common feature in the prisons and indeed the focus tended to be on screening and 'lifestyle issues' rather than a concern for the underlying determinants of health. There was often an absence of a strategic approach to health promotion. There were some good examples of the democratic inclusion of women in prison in shaping services, but this was not widespread and often tokenistic. There were some examples of inequity and the inspection reports from a small number of institutions, illustrated that the health needs of some women remained unmet. CONCLUSIONS: The paper suggests that there is potentially some work before conditions in women's prisons could be described as 'health-promoting', although there are some examples of individual prisons demonstrating good practice. The health promoting prison movement has, implicitly at least, focused on the needs of men in prison and this has been to the exclusion of the female prison population. This does lead to several challenges and the potential for exacerbating health challenges faced by an already marginalised and vulnerable group. Greater focus on the health promotion needs of women in prison is required.

Developing health and wellbeing in prisons: an analysis of prison inspection reports in Scotland.

BACKGROUND: The Scottish Prison Service (SPS) has been long regarded for its progressive policy approach to health promotion in prison. It is one of the few countries with a strategic plan for health promotion implementation. Given the paucity of understanding in relation to the concept of a health promoting prison, this study assessed routinely collected prison inspection data to understand and distil learning in regard the practical implementation of health-promoting prisons. METHODS: Her Majesty's Chief Inspector of Prisons for Scotland (HMIPS) oversees the independent inspection of all prisons. This desk-based study analysed openly accessible inspection reports from a public repository. The sample was limited to inspection reports using the 2018 revised Standards to ensure comparability between reports. Eight unique inspection reports meeting this criterion were downloaded between January and October 2020. The prisons had their inspections undertaken between May 2018 and January 2020. Data from the reports which focused on 'health and wellbeing' were inductively coded using NVivo 12 to support thematic analysis. RESULTS: Results are presented against the values and principles outlined in the SPS' own framework for promoting health in prison. All of the institution reports contained evidence of fairness and justice in their prison and understandings of health inequalities were recognised by staff. There were also examples of mutual (peer) support between people in prison; good relationships between staff and prisoners; and strong health promotion leadership. Conversely, some environmental conditions hindered the development of health promotion - this included staffing shortages and some practices fostering health inequity. Even where a prison was reported as having health promotion activities in place these were focused on a narrow range of individual risk factors such as smoking cessation or substance misuse. Far less attention was paid to wider health determinants. CONCLUSIONS: Scotland has been at the forefront of attempts to embed a health promoting prison philosophy in their justice system. Inspection data focusing on 'health and wellbeing' were analysed, but the analysis suggests that more could be done to ensure a health promoting setting. The way prisons inspectors are assessing health and wellbeing in particular areas is very narrow, with the focus exclusively on healthcare without a wider appreciation of how other areas of prison life can impact.

New models of care: a liaison psychiatry service for medically unexplained symptoms and frequent attenders in primary care.

Aims and method This paper describes the process of setting up and the early results from a new liaison psychiatry service in primary care for people identified as frequent general practice attenders with long-term conditions or medically unexplained symptoms. Using a rapid evidence synthesis, we identified existing service models, mechanisms to identify and refer patients, and outcomes for the service. Considering this evidence, with local contingencies we defined options and resources. We agreed a model to set up a service in three diverse general practices. An evaluation explored the feasibility of the service and of collecting data for clinical, service and economic outcomes. Results High levels of patient and staff satisfaction, and reductions in the utilisation of primary and secondary healthcare, with associated cost savings are reported. Clinical implications A multidisciplinary liaison psychiatry service integrated in primary care is feasible and may be evaluated using routinely collected data.

Ultrasensitive label free electrical detection of insulin in neat blood serum.

Electrical assays potentially offer a highly sensitive, cheap, portable, automated, and multiplexed means of protein biomarker detection, characteristics with an ability to underpin both disease stratification and the development of point of care diagnostics. Most conveniently applied in a reagent free manner, all sensitive assays such as these suffer, however, from profound problems when applied in complex fluids such as blood serum. We report herein, the development, and clinical application, of a highly sensitive and selective electrical insulin biosensor based on a chemisorbed zwittorionic polymer support and a novel reagentless sensing technique based on phase monitoring electrochemical impedance spectroscopy. The polymer adlayer is exceptionally effective in both reducing background response and maintaining receptive antibody binding efficacy, while the non-Faradaic analysis avoids potential interference from background electro-active molecules. Applied to the detection of even a low molecular weight protein (here, insulin), a linear range from 0.1 to 200 pM and an unprecedented femtomolar detection limit are possible in undiluted blood serum.
