Scaling-up an evidence-based intervention for family carers of people with dementia: Current and future costs and outcomes.

OBJECTIVES: The STrAtegies for RelaTives (START) intervention is effective and cost-effective in supporting family carers of people with dementia. It is currently not available to all eligible carers in England. What would be the impacts on service costs and carer health-related quality of life if START was provided to all eligible carers in England, currently and in future? METHODS: Effectiveness and cost-effectiveness data from a previously conducted randomised controlled trial were combined with current and future projections of numbers of people with newly diagnosed dementia to estimate overall and component costs and health-related quality of life outcomes between 2015 (base year for projections) and 2040. RESULTS: Scaling-up START requires investments increasing annually but would lead to significant savings in health and social care costs. Family carers of people with dementia would experience improvements in mental health and quality of life, with clinical effects lasting at least 6 years. Scaling up the START intervention to eligible carers was estimated to cost £9.4 million in 2020, but these costs would lead to annual savings of £68 million, and total annual quality-adjusted life year (QALY) gains of 1247. Although the costs of START would increase to £19.8 million in 2040, savings would rise to £142.7 million and Quality adjusted life years gained to 1883. CONCLUSIONS: Scaling-up START for family carers of people with dementia in England would improve the lives of family carers and reduce public sector costs. Family carers play a vital part in dementia care; evidence-based interventions that help them to maintain this role, such as START, should be available across the country.

Family integrated care: State of art and future perspectives.

Family integrated care (FICare) represents a contemporary approach to health care that involves the active participation of families within the healthcare team. It empowers families to acquire knowledge about the specialised care required for their newborns admitted to neonatal intensive care unit (NICU) and positions them as primary caregivers. Healthcare professionals in this model act as mentors and facilitators during the hospitalisation period. This innovative model has exhibited notable enhancements in both short- and long-term health outcomes for neonates, alongside improved psychological well-being for families and heightened satisfaction among healthcare professionals. Initially designed for stable premature infants and their families, FICare has evolved to include critically ill premature and full-term infants. Findings from recent studies affirm the safety and feasibility of FICare as a NICU-wide model of care, benefiting all infants and families. The envisioned expansion of FICare focusses on sustainability and extending its implementation, recognising the necessity for tailored adaptations to suit varying diverse cultural and socio-economic contexts.

Wet anaerobic digestion of organic fraction of municipal solid waste: experience with long-term pilot plant operation and industrial scale-up.

This paper presents the analysis of a pilot anaerobic digestion plant that operates with organic fraction of municipal solid waste (OFMSW) from a wholesale market and can treat up to 500 kg d-1. The process was monitored for a period of 524 days during which the residue was characterized and the biogas production and methane content were recorded. The organic load rate (OLR) of volatile solids (VS) was 0.89 kg m-3 d-1 and the Hydraulic Retention Time (HRT) was 25 d during the process. The yield was 82 Nm3 tons OFMSW-1 biogas, equivalent to 586 Nm3 tons CH4 VS-1. The results obtained in the pilot plant were used to carry out a technical-economic evaluation of a plant that treats 50 tons of OFMSW from wholesale markets. A production of 3769 Nm3 d-1 of biogas and 2080 Nm3 d-1 of methane is estimated, generating 35.1 MWh d-1 when converted to electricity.

Hydrogel capsules as new delivery system for Trichoderma koningiopsis Th003 to control Rhizoctonia solani in rice (Oryza sativa).

The incorporation of biological control agents (BCAs) such as Trichoderma spp. in agricultural systems favors the transition towards sustainable practices of plant nutrition and diseases control. Novel bioproducts for crop management are called to guarantee sustainable antagonism activity of BCAs and increase the acceptance of the farmers. The encapsulation in polymeric matrices play a prominent role for providing an effective carrier/protector and long-lasting bioproduct. This research aimed to study the influence of biopolymer in hydrogel capsules on survival and shelf-life of T. koningiopsis. Thus, two hydrogel capsules prototypes based on alginate (P1) and amidated pectin (P2), containing conidia of T. koningiopsis Th003 were formulated. Capsules were prepared by the ionic gelation method and calcium gluconate as crosslinker. Conidia releasing under different pH values of the medium, survival of conidia in drying capsules, storage stability, and biocontrol activity against rice sheath blight (Rhizoctonia solani) were studied. P2 prototype provided up to 98% survival to Th003 in fluid bed drying, faster conidia releasing at pH 5.8, storage stability greater than 6 months at 18 °C, and up to 67% of disease reduction. However, both biopolymers facilitate the antagonistic activity against R. solani, and therefore can be incorporated in novel hydrogel capsules-based biopreparations. This work incites to develop novel biopesticides-based formulations with potential to improve the delivery process in the target site and the protection of the active ingredient from the environmental factors.

Standardizing variation: Scaling up clinical genomics in Australia.

PURPOSE: Clinical genomics demands close interaction of physicians, laboratory scientists, and genetic professionals. Taking genomics to scale requires an understanding of the underlying processes from the perspective of nongenetic physicians who are new to the field. We identified components of the processes amenable to adaptation when scaling up clinical genomics. METHODS: Semistructured interviews informed by the Theoretical Domains Framework with nongenetic physicians, who were using clinical genomics in practice, were guided by an annotated process map with 7 steps following the patient's journey. Findings from the individual maps were synthesized into an overview process map and a series of individual maps by common location and specialty. Interviews were analyzed using the Theoretical Domains Framework. RESULTS: In total, 16 nongenetic physicians (eg, nephrologists, immunologists) participated, generating 1 overview and 10 individual process maps. Sixteen common steps were identified across clinical specialties and locations, with variations over 9 steps. We report the potential for standardization across these 9 steps. CONCLUSION: When scaling up complex interventions, it is essential to identify steps where variation can be accommodated. With these results we show how process mapping can be used to identify steps where variation is acceptable during scale up to accommodate adaptation to local context, allowing for the inevitable evolution of factors influencing ongoing implementation and sustainability.

Hybrid AI model for estimating the canopy photosynthesis of eggplants.

Modern models for estimating canopy photosynthetic rates (Ac) can be broadly classified into two categories, namely, process-based mechanistic models and artificial intelligence (AI) models, each category having unique strengths (i.e., process-based models have generalizability to a wide range of situations, and AI models can reproduce a complex process using data without prior knowledge about the underlying mechanism). To exploit the strengths of both categories of models, a novel "hybrid" canopy photosynthesis model that combines process-based models with an AI model was proposed. In the proposed hybrid model, process-based models for single-leaf photosynthesis and image analysis first transform raw inputs (environmental data and canopy images) into the single-leaf photosynthetic rate (AL) and effective leaf area index (Lc)), after which AL and Lc are fed into an artificial neural network (ANN) model to predict Ac. The hybrid model successfully predicted the diurnal cycles of Ac of an eggplant canopy even with a small training dataset and successfully reproduced a typical Ac response to changes in the CO2 concentration outside the range of the training data. The proposed hybrid AI model can provide an effective means to estimate Ac in actual crop fields, where obtaining a large amount of training data is difficult.

Hydrogel capsules as new approach for increasing drying survival of plant biostimulant gram-negative consortium.

Several plant growth-promoting bacteria (PGPB) are gram-negative, and their cell viability is affected during the bio-inoculant production. Hence, formulation-drying processes provide challenges that limit the adoption of these beneficial microorganisms in sustainable agricultural production. Among delivery system strategies for gram-negative PGPB, the encapsulating cells in biopolymeric materials are emerging as a promising alternative. This research aims to evaluate the effect of additives and crosslinking agents on the survival of the consortium of Herbaspirillum frisingense AP21, Azospirillum brasilense D7, and Rhizobium leguminosarum T88 in hydrogel capsules. Three crosslinkers and diverse potential drying protectors were tested. Calcium gluconate provides notable consortium survival advantages regarding colony-forming units (CFUs) (losses of up to 4 log CFU) compared to calcium lactate and calcium chloride (up to 6 log CFU). Additives such as skimmed milk, whey protein, and Gelita® EC improve the recovery of viable cells after the drying process, demonstrating an increase in cell survival of the three bacteria by up to 4 log CFU. The combination of these substances into a capsule prototype extends the storage stability of bacterial consortium up to 3 months at 18 ± 2 °C. This study expands the knowledge for formulating gram-negative PGPB consortium, regarding the crosslinker and drying protector relationship on encapsulation processes with drying survival and further storage stability performance. KEY POINTS: • Hydrogel immobilization formulation approach for PGPB consortium • Enhancing drying survival of gram-negative PGPB consortium • Increasing storage stability of PGPB consortium at 18 °C.

Implementation strategies, facilitators, and barriers to scaling up and sustaining demand generation in family planning, a mixed-methods systematic review.

BACKGROUND: Demand generation aims to increase clients' desire to use family planning. The aim of this work was to systematically summarize strategies, facilitators, and barriers to scaling up and sustaining demand generation in family planning. METHODS: We searched electronic bibliographic databases from inception to October 2022. We included quantitative, qualitative, and mixed methods reports on demand generation strategies in family planning, regardless of country, language, publication status, or methodological limitations. We assessed abstracts, titles and full-text papers according to the inclusion criteria, extracted data, and assessed methodological quality of included reports. We used the convergent integrated approach and a deductive thematic synthesis to summarize demand generation themes and subthemes. We used the health system building blocks to synthesize the factors affecting implementation (barriers and facilitators). We used GRADE-CERQual to assess our confidence in the findings. RESULTS: Forty-six studies (published 1990-2022) were included: forty-one quantitative, one qualitative, and four mixed methods). Three were from one high-income country, and forty three from LMIC settings. Half of reports were judged to be of unclear risk of bias. There were unique yet interrelated strategies of scaling-up demand generation for family planning. Interpersonal communication strategies increase adoption and coverage of modern contraceptive methods, but the effect on sustainability is uncertain. Mass media exposure increases knowledge and positive attitudes and may increase the intention to use modern contraceptive methods. Demand-side financing approaches probably increase awareness of contraceptives and the use of modern contraceptive methods among poor clients. Multifaceted Demand generation approaches probably improve adoption, coverage and sustainability of modern methods use. Factors that influence the success of implementing these strategies include users knowledge about family planning methods, the availability of modern methods, and the accessibility to services. CONCLUSIONS: Demand generation strategies may function independently or supplement each other. The myriad of techniques of the different demand generation strategies, the complexities of family planning services, and human interactions defy simplistic conclusions on how a specific strategy or a bundle of strategies may succeed in increasing and sustaining family planning utilization. TRIAL REGISTRATION: Systematic review registration: Center for Open Science, osf.io/286j5.

Family planning could prevent one third of maternal deaths by allowing women to delay motherhood, avoid unintended pregnancies and subsequent abortions. Demand generation is one of the critical factors for increasing coverage and sustainability of family planning programs. Demand generation activities aim to increase clients' desire to use family planning by changing their attitudes or perceptions about FP or increasing their awareness or knowledge about FP methods and also by improving access to contraceptive services. Many demand generation activities also aim to shift social and cultural norms to affect individual behavior change. Scaling up demand generation and ensuring that demand for family planning is satisfied is essential for achieving universal access to reproductive health-care services. We systematically searched for and summarized reports of strategies to scale up demand generation for family planning. Available evidence shows that interpersonal communication strategies increase adoption and coverage of modern contraceptive methods, but the effect on sustainability is uncertain. Mass media exposure increases knowledge and positive attitudes and may increase the intention to use modern contraceptive methods. The effect of new media is uncertain. Demand-side financing approach probably increase awareness of contraceptives and the use of modern contraceptive methods among poor women. The most apparent factors influencing the success of implementing these strategies include knowledge about family planning methods, especially regarding side effects and health concerns, the availability of modern contraceptive methods, and the accessibility to family planning services.

Implementation strategies, facilitators, and barriers to scaling up and sustaining post pregnancy family planning, a mixed-methods systematic review.

BACKGROUND: Post pregnancy family planning includes both postpartum and post-abortion periods. Post pregnancy women remain one of the most vulnerable groups with high unmet need for family planning. This review aimed to describe and assess the quality of the evidence on implementation strategies, facilitators, and barriers to scaling up and sustaining post pregnancy family planning. METHODS: Electronic bibliographic databases (MEDLINE, PubMed, Scopus, the Cochrane Library, and Global Index Medicus) were searched from inception to October 2022 for primary quantitative, qualitative, and mixed method reports on scaling up post pregnancy family planning. Abstracts, titles, and full-text papers were assessed according to the inclusion criteria to select studies regardless of country, language, publication status, or methodological limitations. Data were extracted and methodological quality assessed using the Mixed Methods Appraisal Tool. The convergent integrated approach and a deductive thematic synthesis were used to identify themes and sub-themes of strategies to scale up post pregnancy family planning. The health system building blocks were used to summarize barriers and facilitators. GRADE-CERQual was used to assess our confidence in the findings. RESULTS: Twenty-nine reports (published 2005-2022) were included: 19 quantitative, 7 qualitative, and 3 mixed methods. Seven were from high-income countries, and twenty-two from LMIC settings. Sixty percent of studies had an unclear risk of bias. The included reports used either separate or bundled strategies for scaling-up post pregnancy family planning. These included strategies for healthcare infrastructure, policy and regulation, financing, human resource, and people at the point of care. Strategies that target the point of care (women and / or their partners) contributed to 89.66% (26/29) of the reports either independently or as part of a bundle. Point of care strategies increase adoption and coverage of post pregnancy contraceptive methods. CONCLUSION: Post pregnancy family planning scaling up strategies, representing a range of styles and settings, were associated with improved post pregnancy contraceptive use. Factors that influence the success of implementing these strategies include issues related to counselling, integration in postnatal or post-abortion care, and religious and social norms.

Family planning could prevent one third of maternal deaths by allowing women to delay motherhood, avoid unintended pregnancies and subsequent abortions. Post pregnancy family planning includes both postpartum and post-abortion periods. Post pregnancy women remain one of the most vulnerable groups with high unmet need for family planning. Scaling up post pregnancy family planning is essential for achieving universal access to reproductive health-care services. Reports of strategies to scale up post pregnancy family planning were systematically reviewed and summarized. These included strategies for healthcare infrastructure, policy and regulation, financing, human resource, and people at the point of care. Strategies that target the point of care (women and/or their partners) contributed to 89.66% (26/29) of the reports either independently or as part of a bundle. Point of care strategies increase adoption and coverage of post pregnancy contraceptive methods. Certain factors influence the success of implementing these strategies, including issues related to counselling, integration in postnatal or post-abortion care, and religious and social norms.

Implementation and scaling-up of an effective mHealth intervention to increase adherence to triage of HPV-positive women (ATICA study): perceptions of health decision-makers and health-care providers.

BACKGROUND: The ATICA study was a Hybrid I type randomized effectiveness-implementation trial that demonstrated effectiveness of a multicomponent mHealth intervention (Up to four SMS messages sent to HPV-positive women, and one SMS message to CHWs to prompt a visit of women with no triage Pap 60 days after a positive-test), to increase adherence to triage of HPV positive women (ATICA Study). We report data on perceptions of health decision-makers and health-care providers regarding the intervention implementation and scaling-up. METHODS: A qualitative study was carried out based on individual, semi-structured interviews with health decision-makers (n = 10) and health-care providers (n = 10). The themes explored were selected and analyzed using domains and constructs of the Consolidated Framework for Implementation Research (CFIR) and the maintenance dimension of the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework. RESULTS: Both health-care providers and decision-makers had a positive assessment of the intervention through most included constructs: knowledge of the intervention, intervention source, design quality, adaptability, compatibility, access to knowledge and information, relative advantage, women's needs, and relative priority. However, some potential barriers were also identified including: complexity, leadership engagement, external policies, economic cost, women needs and maintenance. Stakeholders conditioned the strategy's sustainability to the political commitment of national and provincial health authorities to prioritize cervical cancer prevention, and to the establishment of the ATICA strategy as a programmatic line of work by health authorities. They also highlighted the need to ensure, above all, that there was staff to take Pap tests and carry out the HPV-lab work, and to guarantee a constant provision of HPV-tests. CONCLUSION: Health decision-makers and health-care providers had a positive perception regarding implementation of the multicomponent mHealth intervention designed to increase adherence to triage among women with HPV self-collected tests. This increases the potential for a successful scaling-up of the intervention, with great implications not only for Argentina but also for middle and low-income countries considering using mHealth interventions to enhance the cervical screening/follow-up/treatment process.

How can civil society organizations contribute to the scale-up of comprehensive sexuality education? Presentation of a scaling framework illustrated with examples from Indonesia.

Comprehensive sexuality education (CSE) can substantially contribute to the health and well-being of young people. Yet, most CSE interventions remain limited to the small piloting or research phase and scale-up is often an afterthought at the end of a project. Because of the specificities of CSE, including it being a controversial topic in many contexts and a topic on the fringe between health, education and youth, a specific scaling approach to CSE is needed. The commentary presents a practical framework to support civil society organisations (CSOs), to address barriers to scaling up CSE in their contexts. The utilization and relevance of the framework is demonstrated in this article, by featuring examples from the scale up process of CSE in Indonesia. The framework identifies key principles for scaling up, including: taking a scaling mindset from the start, government ownership and political commitment for scale-up, and identifying the added value of CSOs. The framework starts with a self-assessment by the CSO and then follows four phases: making the case, engaging in dialogue, establishing building blocks and implementation and scale-up. Each of these phases are illustrated with examples from Indonesia.This framework is a call to action with practical guidelines to support CSOs to take on this role, because with the right scaling strategies, the largest generation of young people ever alive can become healthy, empowered and productive adults.

Multi-level stakeholders' perspectives on implementation and scaling up community-based health promotion in Germany.

Community-based health promotion has the potential to address existing health inequities, although such approaches are scarcely scaled up. For a successful scale up, various stakeholders at different levels and sectors need to be involved. The article's aims are to assess what kind of external support communities need for implementation and to identify facilitators and barriers for scaling up community-based health promotion. Two national digital workshops were conducted in Germany with stakeholders at the community level (n = 161) and with stakeholders at the federal and state levels (n = 84). Protocols were compiled and coded using qualitative content analysis. During the first workshop, we revealed 11 themes for external support needs ('Strategic approach', 'Define & compare indicators', 'International human resource', 'Tools & Aids', 'External conduction of the assessment', 'Involvement of people in difficult life situations', 'Overview of actors', 'Moderation', 'Obtain funding', 'Quality assurance/evaluation' and 'External support'). Eleven facilitators and barriers were identified for scaling up ('Assessment and evaluation', 'Intersectoral collaboration and partnerships', 'Communication', 'Characteristics of the program', 'Political and legal conditions', 'Political support', 'Local coordinator', 'Resources', 'Participation', 'Strategic planning/methods' and 'Intermediary organization'). The identified results provide practice-based evidence on support needed for scaling up, facilitators that promote scaling up and barriers that might hinder scaling up community-based health promotion in Germany. In a next step, this practice-based evidence needs to be systematically integrated with scientific-based evidence on key components for scaling up such approaches for the development of an effective scaling-up concept.

The major aim of this article is to describe how German stakeholders at different levels (local, federal and state) from various sectors (e.g. health, social or sports) were involved to develop a scaling-up concept for a community-based health promotion approach with a focus on health equity in the field of physical activity promotion. Different actors from science, policy and practice discussed facilitators and barriers for the scale up and what external support communities need to implement a community-based health promotion approach, with a focus on people in difficult life situations (e.g. individuals with social disadvantages). We identified 14 different kind of support needs and 11 facilitators and barriers for scaling up community-based health promotion approaches in the field of physical activity promotion. Various actors emphasized the need for improved collaboration and partnerships across several sectors as well as changes in current political and legal conditions. Furthermore, the role and some characteristics of an external organization to support a successful scaling-up process were also discussed among actors.

Gearing to success with national breastfeeding programmes: The Becoming Breastfeeding Friendly (BBF) initiative experience.

Evidence-based policy toolboxes are essential for decision makers to effectively invest in and scale up maternal-child health and nutrition programs, and breastfeeding is no exception. This special issue focuses on the experiences implementing the Becoming Breastfeeding Friendly (BBF) toolbox in England, Scotland, and Wales. BBF is an initiative that includes a toolbox for decision making based on the Complex Adaptive System-based Breastfeeding Gear Model. The BBF initiative experience in Great Britain presented in this special issue illustrates how versatile BBF is as it can be readily adapted to the specific application context. In this instance one country, England was trained by the Yale School of Public Health team that developed BBF. England, in turn, trained and assisted Scotland and Wales with the implementation and oversight of BBF in those countries. The positive experience implementing BBF in Great Britain is fully consistent with findings related to this initiative in other countries with contrasting economic, social, political and health care systems; including Germany, Ghana, Mexico, Myanmar, and Samoa. In all instances BBF has led to breastfeeding policy improvements with strong implications for enabling breastfeeding environments including maternity benefits, workforce development, the Baby Friendly Hospital Initiative and behavior change communication campaigns. In conclusion, BBF is a powerful tool to help guide the effective scaling up of evidence-based programmes to advance breastfeeding protection, promotion and support globally.

Implementing the Becoming Breastfeeding Friendly initiative in Scotland.

Despite strong policy support in Scotland, United Kingdom, key challenges to scaling up promotion, protection and support for breastfeeding remain. These include low breastfeeding rates and socioeconomic and regional inequalities. The Becoming Breastfeeding-Friendly (BBF) process was implemented to highlight actions that could address these challenges. The Scottish BBF committee employed an iterative process of documentary analysis and evidence reviews supplemented by 18 interviews with key informants. The data were mapped to BBF benchmarks and each gear was scored accordingly. Nineteen draft recommendations addressing policy and practice gaps were prioritised. Ten recommendations were grouped into eight themes, which cross-cut the BBF gears. The process took place from May 2018 to May 2019. The overall BBF Index score for Scotland was 2.4 indicating a strong scaling-up environment for breastfeeding. Five gears were assessed as strong gear strength, and the remaining three were judged as moderate gear strength. Three recommendation themes illuminate strengths and areas for development. The theme 'reinforcing political will' showed effective leadership, strong policies and significant investment in supporting breastfeeding and highlights actions to sustain this. The theme 'strengthening and coordinating breastfeeding messages' revealed a need for coordination between government, health services and the third sector. The theme 'promoting a supportive return to work environment' highlighted that, while employment legislation is not devolved to the Scottish government, action could be taken by employers to optimise an enabling environment for breastfeeding. The BBF process identified strengths and triggered actions to enhance breastfeeding promotion, protection and support in Scotland.

A Modular Tubular Flow System with Replaceable Photocatalyst Membranes for Scalable Coupling and Hydrogenation.

Heterogeneous photocatalysis is effective for the selective synthesis of value-added chemicals at lab-scale, yet falls short of requirements for mass production (low cost and user friendliness). Here we report the design and fabrication of a modular tubular flow system embedded with replaceable photocatalyst membranes for scalable photocatalytic C-C, C-N homocoupling and hydrogenation reactions, which can be operated in either circular and continuous flow mode with high performance. The photocatalyst membranes almost fully occupy the volume of the reactor, thus enabling optimal absorption of the incident light. Additionally, the porous structured photocatalyst membranes facilitate the mass transfer of the reactants to efficiently use the active sites, resulting in 0th -order reaction kinetics and a high space-time yield compared to the batch reaction system at practical application levels and prolonged reaction times.

Scaling Up Public Health Interventions: Engaging Partners Across Multiple Levels.

Advancing the science of intervention scale-up is essential to increasing the impact of effective interventions at the regional and national levels. In contrast with work in high-income countries (HICs), where scale-up research has been limited, researchers in low- and middle-income countries (LMICs) have conducted numerous studies on the regional and national scale-up of interventions. In this article, we review the state of the science on intervention scale-up in both HICs and LMICs. We provide an introduction to the elements of scale-up followed by a description of the scale-up process, with an illustrative case study from our own research. We then present findings from a scoping review comparing scale-up studies in LMIC and HIC settings. We conclude with lessons learned and recommendations for improving scale-up research.

Guidelines on reporting treatment conditions for emerging technologies in food processing.

In the last decades, different non-thermal and thermal technologies have been developed for food processing. However, in many cases, it is not clear which experimental parameters must be reported to guarantee the experiments' reproducibility and provide the food industry a straightforward way to scale-up these technologies. Since reproducibility is one of the most important science features, the current work aims to improve the reproducibility of studies on emerging technologies for food processing by providing guidelines on reporting treatment conditions of thermal and non-thermal technologies. Infrared heating, microwave heating, ohmic heating and radiofrequency heating are addressed as advanced thermal technologies and isostatic high pressure, ultra-high-pressure homogenization sterilization, high-pressure homogenization, microfluidization, irradiation, plasma technologies, power ultrasound, pressure change technology, pulsed electric fields, pulsed light and supercritical CO2 are approached as non-thermal technologies. Finally, growing points and perspectives are highlighted.

What are the current and projected future cost and health-related quality of life implications of scaling up cognitive stimulation therapy?

OBJECTIVES: Cognitive stimulation therapy (CST) is one of the few non-pharmacological interventions for people living with dementia shown to be effective and cost-effective. What are the current and future cost and health-related quality of life implications of scaling-up CST to eligible new cases of dementia in England? METHODS/DESIGN: Data from trials were combined with microsimulation and macrosimulation modelling to project future prevalence, needs and costs. Health and social costs, unpaid care costs and quality-adjusted life years (QALYs) were compared with and without scaling-up of CST and follow-on maintenance CST (MCST). RESULTS: Scaling-up group CST requires year-on-year increases in expenditure (mainly on staff), but these would be partially offset by reductions in health and care costs. Unpaid care costs would increase. Scaling-up MCST would also require additional expenditure, but without generating savings elsewhere. There would be improvements in general cognitive functioning and health-related quality of life, summarised in terms of QALY gains. Cost per QALY for CST alone would increase from £12,596 in 2015 to £19,573 by 2040, which is below the threshold for cost-effectiveness used by the National Institute for Health and Care Excellence (NICE). Cost per QALY for CST and MCST combined would grow from £19,883 in 2015 to £30,906 by 2040, making it less likely to be recommended by NICE on cost-effectiveness grounds. CONCLUSIONS: Scaling-up CST England for people with incident dementia can improve lives in an affordable, cost-effective manner. Adding MCST also improves health-related quality of life, but the economic evidence is less compelling.

Assessing the scalability of an integrated falls prevention service for community-dwelling older people: a mixed methods study.

BACKGROUND: There is growing acknowledgement of the need for a phased approach to scaling up health interventions, beginning with an assessment of 'scalability', that is, the capacity of an individual intervention to be scaled up. This study aims to assess the scalability of a multi-component integrated falls prevention service for community-dwelling older people and to examine the applicability of the Intervention Scalability Assessment Tool (ISAT). The ISAT consists of 10 domains for consideration when determining the scalability of an intervention, and each domain comprises a series of questions aimed at examining readiness for scale-up. METHODS: Multiple methods were used sequentially as recommended by the ISAT: a review of policy documents, results from a service evaluation and falls-related literature; one-to-one interviews (n = 11) with key stakeholders involved in management and oversight of the service; and a follow-up online questionnaire (n = 10) with stakeholders to rate scalability and provide further feedback on reasons for their scores. RESULTS: Three of the ISAT domains were rated highly by the participants. Analysis of the qualitative feedback and documents indicated that the issue of falls prevention among older people was of sufficient priority to warrant scale-up of the service and that the service aligned with national health policy priorities. Some participants also noted that benefits of the service could potentially outweigh costs through reduced hospital admissions and serious injuries such as hip fracture. The remaining domains received a moderate score from participants, however, indicating considerable barriers to scale-up. In the qualitative feedback, barriers identified included the perceived need for more healthcare staff to deliver components of the service, for additional infrastructure such as adequate room space, and for an integrated electronic patient management system linking primary and secondary care and to prevent duplication of services. CONCLUSIONS: Plans to scale up the service are currently under review given the practical barriers that need to be addressed. The ISAT provides a systematic and structured framework for examining the scalability of this multi-component falls prevention intervention, although the iterative nature of the process and detailed and technical nature of its questions require considerable time and knowledge of the service to complete.

Factors influencing sustainability and scale-up of rural primary healthcare memory clinics: perspectives of clinic team members.

BACKGROUND: The aging of rural populations contributes to growing numbers of people with dementia in rural areas. Despite the key role of primary healthcare in rural settings there is limited research on effective models for dementia care, or evidence on sustaining and scaling them. The purpose of this study was to identify factors influencing sustainability and scale-up of rural primary care based memory clinics from the perspective of healthcare providers involved in their design and delivery. METHODS: Participants were members of four interdisciplinary rural memory clinic teams in the Canadian province of Saskatchewan. A qualitative cross-sectional and retrospective study design was conducted. Data were collected via 6 focus groups (n = 40) and 16 workgroup meetings held with teams over 1 year post-implementation (n = 100). An inductive thematic analysis was used to identify themes. RESULTS: Eleven themes were identified (five that influenced both sustainability and scale-up, three related to sustainability, and three related to scale-up), encompassing team, organizational, and intervention-based factors. Factors that influenced both sustainability and scale-up were positive outcomes for patients and families, access to well-developed clinic processes and tools, a confident clinic leader-champion, facilitation by local facilitators and the researchers, and organizational and leadership support. Study findings revealed the importance of particular factors in the rural context, including facilitation to support team activities, a proven ready-to-use model, continuity of team members, and mentoring. CONCLUSIONS: Interdisciplinary models of dementia care are feasible in rural settings if the right conditions and supports are maintained. Team-based factors were key to sustaining and scaling the innovation.
