This study reports on a survey on project managers' priorities. The survey used ISO 21500 as a scaffold to ask various respondents, like junior, experienced, and senior project managers, project sponsors, and students, to share their perceptions on the priorities for junior project managers. The respondent groups shared similar perceptions. Furthermore, project type and sector had little effect on junior project managers' priorities. Experienced and senior project managers shared their own priorities as well. The perceptions of priorities for junior, experienced, and senior project managers were mostly alike. However, experienced and senior project managers' priorities seemed slightly more affected by project type and sector. A session with experts in project management and teaching project management highlighted that the results for junior project managers could provide accents for introducing project management to students in higher education, provided the entire playing field of project management is also introduced.

Medical technology ,R855-855.5 - Abstract
BackgroundArtificial intelligence (AI)–powered technologies are being increasingly used in almost all fields, including medicine. However, to successfully implement medical AI applications, ensuring trust and acceptance toward such technologies is crucial for their successful spread and timely adoption worldwide. Although AI applications in medicine provide advantages to the current health care system, there are also various associated challenges regarding, for instance, data privacy, accountability, and equity and fairness, which could hinder medical AI application implementation. ObjectiveThe aim of this study was to identify factors related to trust in and acceptance of novel AI-powered medical technologies and to assess the relevance of those factors among relevant stakeholders. MethodsThis study used a mixed methods design. First, a rapid review of the existing literature was conducted, aiming to identify various factors related to trust in and acceptance of novel AI applications in medicine. Next, an electronic survey including the rapid review–derived factors was disseminated among key stakeholder groups. Participants (N=22) were asked to assess on a 5-point Likert scale (1=irrelevant to 5=relevant) to what extent they thought the various factors (N=19) were relevant to trust in and acceptance of novel AI applications in medicine. ResultsThe rapid review (N=32 papers) yielded 110 factors related to trust and 77 factors related to acceptance toward AI technology in medicine. Closely related factors were assigned to 1 of the 19 overarching umbrella factors, which were further grouped into 4 categories: human-related (ie, the type of institution AI professionals originate from), technology-related (ie, the explainability and transparency of AI application processes and outcomes), ethical and legal (ie, data use transparency), and additional factors (ie, AI applications being environment friendly). The categorized 19 umbrella factors were presented as survey statements, which were evaluated by relevant stakeholders. Survey participants (N=22) represented researchers (n=18, 82%), technology providers (n=5, 23%), hospital staff (n=3, 14%), and policy makers (n=3, 14%). Of the 19 factors, 16 (84%) human-related, technology-related, ethical and legal, and additional factors were considered to be of high relevance to trust in and acceptance of novel AI applications in medicine. The patient’s gender, age, and education level were found to be of low relevance (3/19, 16%). ConclusionsThe results of this study could help the implementers of medical AI applications to understand what drives trust and acceptance toward AI-powered technologies among key stakeholders in medicine. Consequently, this would allow the implementers to identify strategies that facilitate trust in and acceptance of medical AI applications among key stakeholders and potential users.

Purpose: Achieving greater health and social care integration is a policy priority in many countries, but challenges remain. We focused on governance and accountability for integrated care and explored arrangements that shape more integrated delivery models or systems in Italy, the Netherlands and Scotland. We also examined how the COVID-19 pandemic affected existing governance arrangements. Design/methodology/approach: A case study approach involving document review and semi-structured interviews with 35 stakeholders in 10 study sites between February 2021 and April 2022. We used the Transparency, Accountability, Participation, Integrity and Capability (TAPIC) framework to guide our analytical enquiry. Findings: Study sites ranged from bottom-up voluntary agreements in the Netherlands to top-down mandated integration in Scotland. Interviews identified seven themes that were seen to have helped or hindered integration efforts locally. Participants described a disconnect between what national or regional governments aspire to achieve and their own efforts to implement this vision. This resulted in blurred, and sometimes contradictory, lines of accountability between the centre and local sites. Flexibility and time to allow for national policies to be adapted to local contexts, and engaged local leaders, were seen to be key to delivering the integration agenda. Health care, and in particular acute hospital care, was reported to dominate social care in terms of policies, resource allocation and national monitoring systems, thereby undermining better collaboration locally. The pandemic highlighted and exacerbated existing strengths and weaknesses but was not seen as a major disruptor to the overall vision for the health and social care system. Research limitations: We included a relatively small number of interviews per study site, limiting our ability to explore complexities within sites. Originality: This study highlights that governance is relatively neglected as a focus of attention in this context but addressing governance challenges is key for successful collaboration.

Medicine ,Science - Abstract
Objectives1) to analyse the total average healthcare costs of a patient with an out-of-hospital cardiac arrest (OHCA), as well as estimating the operational costs of the citizen-rescuer system (CRS); 2) to conduct an early modelling of the effects and healthcare costs of the Dutch CRS in comparison to no CRS.MethodsA health economic modelling study was conducted. Adult patients with OHCA from cardiac causes in the province of Limburg (the Netherlands) were included. The time horizon was from OHCA occurrence up to one year after hospital discharge. First, the total average healthcare costs of OHCA patients were analysed as well as the yearly operating costs of the CRS. Second, an early modelling was conducted to compare from the healthcare perspective the healthcare costs of OHCA patients with the CRS being activated but no responders attended (CRS-NV) versus the CRS being activated with attendance of ≥1 responder(s) (CRS-V).ResultsThe total average healthcare costs per patient are €42,533. The yearly operating costs for the CRS are approximately €1.5 million per year in the Netherlands. The early modelling of costs and effects showed that the incremental healthcare costs per patient thus were €4,131 in the CRS-V versus the CRS-NV group (€25,184 in the CRS-V group and €21,053 in the CRS-NV group). Incremental quality-adjusted life years (QALYs) was 5 per 100 patients (16 per 100 patients in the CRS-V group versus 11 per 100 patients in the CRS-NV group). The incremental cost-effectiveness ratio (ICER) was €79,662 per QALY for the CRS-V group.ConclusionThis study shows that patients in the CSR-V group had additional health care costs of €4,131 per patient compared to patients in the CRS-NV group. This increase is caused by patients surviving more often, who then continue to utilise health services, which results in a (logic) increase in healthcare costs. For future research, accurate and up-to-date data on effectiveness and costs of the CRS needs to be collected.

Medicine ,Science - Abstract
In a previous rapid realist review (RRR) of international literature insight was provided into how, why, and under what circumstances person-centred care (PCC) in primary care works (or not) among others for people with low health literacy skills and for people with a diverse ethnic and socioeconomic background, by establishing a middle-range programme theory (PT), which describes the relationship between context items, mechanisms, and outcomes. Since the application of PCC in primary care in the Dutch setting is expected to differ from other countries, the objective of this study is to validate the items (face validity) resulting from the RRR for the Dutch setting by assessing consensus on the relevance of items. Four focus group discussions with patient representatives and patients with limited health literacy skills (n = 14), and primary care professionals (n = 11) were held partly combined with a Delphi-study. Items were added to refine the middle-range PT for the Dutch primary care setting. These items indicated that in order to optimally align care to the patient tailored supporting material that is developed together with the target group is important, next to providing tailored communication. Healthcare providers (HCPs) and patients need to have a shared vision and set up goals and action plans together. HCPs should stimulate patient’s self-efficacy, need to be aware of the patient’s (social) circumstances and work in a culturally sensitive way. Better integration between information and communications technology systems, flexible payment models, and patients access to documents, and recorded consultations should be in place. This may result in better alignment of care to the needs of patients, improved accessibility to care, improved patient’s self-efficacy, and improved health-related quality of life. On the long-term higher cost-effectiveness and a higher quality of healthcare can be realised. In conclusion, this study shows that for PCC to be effective in Dutch primary care, the PT based on international literature was refined by leaving out items and adding new items for which insufficient or sufficient consensus, respectively, was found.

Medicine - Abstract
BackgroundNotwithstanding the benefits of heat and moisture exchangers (HMEs) in both clinical research and practice, a gap exists between the optimal physiological humidification created through the nasal function and the humidification capacity of HMEs for patients after total laryngectomy. In this study, 5 new HMEs (Provox Life) specialized for situational use with improved humidification capacities were evaluated. ObjectiveThis study aims to evaluate the effectiveness of the existing HMEs, assess the potential effectiveness of the new HMEs, and elicit expert judgments on the new HMEs’ expected effectiveness and impact on health care use. MethodsFirst, a rapid literature review (RLR) was performed to identify evidence on the clinical outcomes, health outcomes, and complications of HMEs in patients who underwent laryngectomy. Second, semistructured interviews with German experts (n=4) were conducted to validate the findings of the RLR and identify reasonable expectations regarding the potential of the new HMEs. Third, a structured expert elicitation among German experts (n=19) was used to generate quantitative evidence on the expected effectiveness of the new HMEs in clinical and health outcomes. ResultsThe RLR (n=10) demonstrated that HME use by patients has advantages compared with no HME use concerning breathing resistance, tracheal dryness and irritation, mucus production and plugging, frequency of cough and forced expectorations, sleep quality, voice quality, use of physiotherapy, tracheobronchitis or pneumonia episodes, quality of life, and patient satisfaction. From the expert interviews and structured expert elicitation, it was found that, on average, experts expect that compared with the second-generation HMEs, the new HMEs will lead to a decrease in tracheal dryness or irritation (51%, SD 24%, of patients), mucus plug events (33%, SD 32%, of patients), mucus production (53%, SD 22%, of patients), physiotherapy (0.74, SD 0.70, days) and pulmonary infections (34%, SD 32%) and an increase or improvement in speech quality (25%, SD 23%, of patients), social contacts (13%, SD 18%), quality of life (33%, SD 30%), and patient satisfaction (44%, SD 30%). An improvement in breathing (53%, SD 28%, of patients) and shortness of breath (48%, SD 25%, of patients) was expected. The average number of daily cough periods and forced expectorations was expected to be 2.95 (SD 1.61) and 2.46 (SD 1.42), respectively. Experts expect that, on average, less than half of the patients will experience sleeping problems (48%, SD 22%) and psychosocial problems (24%, SD 20%). ConclusionsAccording to German experts, it is expected that the new HMEs with improved humidification levels will lead to additional (clinical) effectiveness on pulmonary health and an improved overall quality of life of patients compared with the currently available HMEs.

Medicine ,Science - Abstract
Background Expected rise in the demand for healthcare and a dropping supply of healthcare professionals, has generated an increased interest in the most effective deployment of healthcare professionals. Consequently, task shifting has become a common strategy to redistribute tasks between established professional groups, however, little is known about the effects of shifting tasks to emerging professional groups. The aim of this study was to evaluate a legal amendment to facilitate task shifting to an emerging profession in Dutch healthcare: Clinical Technologists (CTs). CTs were introduced and provided an Extended Scope of Practice (ESP) to perform nine ‘reserved procedures’ independently. Methods A concurrent multi-phase mixed methods study was used to evaluate whether a legal amendment to facilitate task shifting to CTs was effective and efficient. Results The results show that CTs use their ESP frequently to perform five categories of reserved procedures independently and suggest that the ESP increased the efficiency of care delivery for those procedures. Additionally, the findings highlight that task shifting was influenced by the setting in which CTs worked, time allotted to patient-contact as well as external factors (e.g., financing). Conclusions This study provides tentative lessons for policymakers on how task shifting to emerging professional groups can be improved. Providing a legal amendment to facilitate task shifting to CTs seems to be effective and efficient. However, it also poses multiple challenges. While established professional groups can face similar challenges, it is likely that these are exacerbated for emerging professional groups, particularly when shifting tasks occurs horizontally.

Introduction: Violet Program (ViP) was developed 'to' address the current home palliative service gap for individuals with life limiting non-cancer conditions residing in the Eastern part of Singapore. While its basic principles and processes have been planned and implemented, how ViP works, for whom and in what circumstances are not yet well understood. Therefore, we propose for a realist evaluation (RE) – a theory-based evaluation, to address the current knowledge gaps. Evaluation findings may guide, support further development and broader uptake of ViP. Methods and Analysis: This study will be conducted in three phases: 1. development of initial program theory (IPT), 2. testing of programme theory, and 3. refinement of IPT. First, IPT will be elicited through review of programme documents, scoping review of reviews and in-depth interviews with stakeholders involved in the conceptualization of ViP. Then, a convergent mixed method study will be conducted to assess contexts (C), mechanisms (M) and outcomes (O) to test the IPT through interviews with stakeholders, surveys and analysis of program and administrative databases. Based on findings gathered and through consultation with respective stakeholders, IPT will be refined to highlight what works (outcomes), how (mechanisms) and for whom under what conditions (contexts).

Science - Abstract
Background: Recognising the importance of addressing ethics and research integrity (ERI) in Europe, in 2017, the All European Academies (ALLEA) published a revised and updated European Code of Conduct for Research Integrity (ECoC). Consistent application of the ECoC by researchers across Europe will require its widespread dissemination, as well as an innovative training programme and novel tools to enable researchers to truly uphold and internalise the principles and practices listed in the Code.Aim: VIRT2UE aims to develop a sustainable train-the-trainer blended learning programme enabling contextualised ERI teaching across Europe focusing on understanding and upholding the principles and practices of the ECoC.Vision: The VIRT2UE project recognises that researchers not only need to have knowledge of the ECoC, but also to be able to truly uphold and internalise the principles underpinning the code. They need to learn how to integrate them into their everyday practice and understand how to act in concrete situations. VIRT2UE addresses this challenge by providing ERI trainers and researchers with an innovative blended (i.e. combined online and off-line approaches) learning programme that draws on a toolbox of educational resources and incorporates an e-learning course (including a YouTube channel) and face-to-face sessions designed to foster moral virtues. ERI trainers and researchers from academia and industry will have open access to online teaching material. Moreover, ERI trainers will learn how to facilitate face-to-face sessions of researchers, which focus on learning how to apply the content of the teaching material to concrete situations in daily practice.Objectives: VIRT2UE’s work packages (WP) will: conduct a conceptual mapping amongst stakeholders to identify and rank the virtues which are essential for good scientific practice and their relationship to the principles and practices of the ECoC (WP1); identify and consult ERI trainers and the wider scientific community to understand existing capacity and deficiencies in ERI educational resources (WP2); develop the face-to-face component of the train-the-trainer programme which provides trainers with tools to foster researchers’ virtues and promote the ECoC and iteratively develop the programme based on evaluations (WP3); produce educational materials for online learning by researchers and trainers (WP4); implement and disseminate the train-the-trainer programme across Europe, ensuring the training of sufficient trainers for each country and build capacity and consistency by focusing on underdeveloped regions and unifying fragmented efforts (WP5); and develop the online training platform and user interface, which will be instrumental in evaluation of trainers’ and researchers’ needs and project sustainability (WP6).Impact: The VIRT2UE training programme will promote consistent application of the ECoC across Europe. The programme will affect behaviour on the individual level of trainers and researchers – simultaneously developing an understanding of the ECoC and other ERI issues, whilst also developing scientific virtues, enabling the application of the acquired knowledge to concrete situations and complex moral dilemmas. Through a dedicated embedding strategy, the programme will also have an impact on an institutional level. The train-the-trainer approach multiplies the impact of the programme by reaching current and future European ERI trainers and, subsequently, the researchers they train.

- Abstract
RIVM rapport:Sinds 2006 mogen bepaalde agrarische bedrijven in Nederland meer dierlijke mest op hun land gebruiken dan de Europese Nitraatrichtlijn voorschrijft. Zij moeten hiervoor een vergunning hebben en aan bepaalde voorwaarden voldoen, zoals minimaal 80 procent grasland hebben. Deze verruiming heet derogatie. Het RIVM en Wageningen Economic Research meten elk jaar de invloed van de waterkwaliteit bij driehonderd bedrijven die van derogatie gebruikmaken. Op de derogatiebedrijven daalde de concentratie nitraat in het grondwater tussen 2006 en 2017. In de jaren daarna steeg de concentratie, vooral in de Zandregio. Deze stijging komt waarschijnlijk door de droge jaren van 2018 tot en met 2020. Door droogte wordt er minder nitraat in de bodem afgebroken, waardoor de nitraatconcentratie in het grondwater stijgt. Sinds 2021 daalde de nitraatconcentratie weer in alle regio’s en deze daling zet door in 2022, waarschijnlijk door een aantal nattere jaren. In 2023 lag in de meeste regio's de gemiddelde concentratie nitraat in het bovenste grondwater op derogatiebedrijven onder de norm van 50 milligram per liter grondwater. Alleen in het zuiden en midden van de Zandregio was de concentratie nitraat gemiddeld genomen even hoog als de norm. In deze regio had 47 procent van de derogatiebedrijven een concentratie boven de norm. Door veranderingen in het mestbeleid en de bedrijfsvoering gebruiken boeren minder stikstof uit dierlijke mest. Het ‘stikstofbodemoverschot’ is daardoor gemiddeld gedaald, vooral tussen 2006 en 2017. Dit betekent dat er minder stikstof in de bodem overblijft dat als nitraat met regenwater kan wegzakken naar diepere lagen in de bodem, en uiteindelijk in het grondwater terechtkomt. Vanaf 2018 tot 2022 schommelde het stikstofbodemoverschot. In 2022 hebben derogatiebedrijven gemiddeld 228 kilogram stikstof uit dierlijke mest per hectare gebruikt. Dat is minder dan de 230 of 250 kilogram stikstof per hectare die, afhankelijk van de bodemsoort en regio, is toegestaan. De m, Dutch farms that meet certain conditions, such as a minimum of 80 percent acreage as grassland, may use more animal manure than the general limit prescribed by the European Nitrates Directive. This partial exemption is referred to as ‘derogation’. The Dutch National Institute for Public Health and the Environment (RIVM) and Wageningen Economic Research monitor the water quality on 300 farms in the derogation monitoring network. On derogation farms, the concentration of nitrate in groundwater decreased between 2006 and 2017. In the following years, nitrate concentrations increased, especially in the Sand region. This increase is probably due to the droughts occurring in 2018-2020. Due to drought, less nitrogen is broken down, causing the nitrate concentration in groundwater to rise. Since 2021, the nitrate concentration in all regions has decreased, and this decrease continued in 2022, most likely due to some wetter years. In 2023, average nitrate concentrations in the upper metre of the groundwater were below the EU standard of 50 milligrams per litre for most regions. Only in the south and east of the Sand region was the concentration, on average, equal to the standard. In this region, 47 percent of the derogation farms are above the standard. Changes in legislation and management have resulted in farmers using less nitrogen from animal manure. As a result, the nitrogen surplus on the soil surface balance has decreased, especially between 2006 and 2017. This means that less nitrogen, in the form of nitrate, was available to leach to the lower parts of soil profiles and eventually into the groundwater. From 2018 to 2022, the soil surplus fluctuates. On average, derogation farms have used 228 kilograms of nitrogen from animal manure per hectare in 2022. This is less than the 230 or 250 kilograms of nitrogen per hectare allowed, depending on the soil type and region. The monitoring was commissioned by the Ministry of Agriculture, Nature, and Food Quality. In September

BLOOD flow measurement ,COMPUTED tomography ,TECHNOLOGY assessment ,MAJOR adverse cardiovascular events ,CHEST pain - Abstract
Objectives: The aim of this early-stage Health Technology Assessment (HTA) was to assess the difference in healthcare costs and effects of fractional flow reserve derived from coronary computed tomography (FFRct) compared to standard diagnostics in patients with stable chest pain in The Netherlands. Methods: A decision-tree model was developed to assess the difference in total costs from the hospital perspective, probability of correct diagnoses, and risk of major adverse cardiovascular events at one year follow-up. One-way sensitivity analyses were conducted to determine the main drivers of the cost difference between the strategies. A threshold analysis on the added price of FFRct analysis (computational analysis only) was conducted. Results: The mean one-year costs were €2,680 per patient for FFRct and €2,915 per patient for standard diagnostics. The one-year probability of correct diagnoses was 0.78 and 0.61, and the probability of major adverse cardiovascular events was 1.92x10
-5 and 0.01, respectively. The probability and costs of revascularization and the specificity of coronary computed tomography angiography had the greatest effect on the difference in costs between the strategies. The added price of FFRct analysis should be below €935 per patient to be considered the least costly option. Conclusions: The early-stage HTA findings suggest that FFRct may reduce total healthcare spending, probability of incorrect diagnoses, and major adverse cardiovascular events compared to current diagnostics for patients with stable chest pain in the Dutch healthcare setting over one year. Future cost-effectiveness studies should determine a value-based pricing for FFRct and quantify the economic value of the anticipated therapeutic impact. [ABSTRACT FROM AUTHOR]- Published

Abstract Background Accessibility to efficient and person-centered healthcare delivery drives healthcare transformation in many countries. In Singapore, specialist outpatient clinics (SOCs) are commonly congested due to increasing demands for chronic care. To improve this situation, the National University Health System (NUHS) Regional Health System (RHS) started an integrated care initiative,the Right-Site Care (RSC) program in 2014. Through collaborations between SOCs at the National University Hospital and primary and community care (PCC) clinics in the western region of the county, the program was designed to facilitate timely discharge and appropriate transition of patients, who no longer required specialist care, to the community. The aim of this study was to evaluate the implementation fidelity of the NUHS RHS RSC program using the modified Conceptual Framework for Implementation Fidelity (CFIF), at three distinct levels; providers, organizational, and system levels to explain outcomes of the program and to inform further development of (similar) programs. Methods A convergent parallel mixed methods study using the realist evaluation approach was used. Data were collected between 2016 and 2018 through non-participatory observations, reviews of medical records and program database, together with semi-structured interviews with healthcare providers. Triangulation of data streams was applied guided by the modified CFIF. Results Our findings showed four out of six program components were implemented with low level of fidelity, and 9112 suitable patients were referred to the program while 3032 (33.3%) declined to be enrolled. Moderating factors found to influence fidelity included: (i) complexity of program, (ii) evolving providers’ responsiveness, (iii) facilitation through synergistic partnership, training of PCC providers by specialists and supportive structures: care coordinators, guiding protocols, shared electronic medical record and shared pharmacy, (iv) lack of organization reinforcement, and (v) mismatch between program goals, healthcare financing and providers’ reimbursement. Conclusion Functional integration alone is insufficient for a successful right-site care program implementation. Improvement in relationships between providers, organizations, and patients are also warranted for further development of the program.

Abstract Background To examine how the knowledge transfer processes unfolded within SCIROCCO, a EU funded project (3rd Health Programme (2014–2020)) that aimed to facilitate the process of knowledge sharing across five European regions, to speed up adoption and scaling-up of integrated care initiatives. Methods A qualitative multi-method design was used. Data collection methods included focus groups, project documents and action plans of the regions. The data was analysed using a qualitative content-analysis procedure, which was guided by the frameworks of knowledge exchange and the why, whose, what, how framework for knowledge mobilisers. Results All five components (including the themes) of knowledge exchange could be identified in the approach developed on the knowledge transfer processes. The four questions and accompanying categories of the framework of knowledge mobilisation were also identified to a large degree. Conclusions The observed incorporation of distinct forms of knowledge from multiple sources and the observed dynamic and fluid knowledge transfer processes both suggest that SCIROCCO developed a comprehensive knowledge transfer approach aiming to enable the adoption and scaling-up of integrated care. Overall, the multi-method qualitative nature of this research has allowed some new and practical insights in the knowledge transfer activities on integrated care between several European regions. To obtain a clear understanding of the content of the knowledge transfer approaches, which could assist the operationalising of models to support the evaluation of knowledge transfer activities, it is strongly recommended that further research of this type should be conducted in other research settings.

ObjectiveTo assess the cost-effectiveness of preterm preeclampsia (PE) screening versus routine screening based on maternal characteristics in Germany and Switzerland.MethodsA health economic model was used to analyse the cost-effectiveness of PE screening versus routine screening based on maternal characteristics. The analysis was conducted from the healthcare perspective with a time horizon of one year from the start of pregnancy. The main outcome measures were incremental health care costs and incremental costs per PE case averted.ResultsThe incremental health care costs for PE screening versus routine screening per woman were €14 in Germany, and -CHF42 in Switzerland, the latter representing cost savings. In Germany, the incremental costs per PE case averted were €3,795. In Switzerland, PE screening was dominant. The most influential parameter in the one-way sensitivity analysis was the cost of PE screening (Germany) and the probability of preterm PE in routine screening (Switzerland). In Germany, at a willingness-to-pay for one PE case avoided of €4,200, PE screening had a probability of more than 50% of being cost-effective compared to routine screening. In Switzerland, at a willingness-to-pay of CHF0, PE screening had a 78% probability of being the most cost-effective screening strategy.ConclusionFor Switzerland, PE screening is expected to be cost saving in comparison to routine screening. For Germany, the additional health care costs per woman were expected to be €14. Future cost-effectiveness studies should be conducted with a longer time horizon.

Background Atrial fibrillation (AF) is the most common arrythmia and is associated with costly morbidity such as stroke and heart failure. Mobile health (mHealth) has potential to help bridge the gaps of traditional healthcare models that may be poorly suited to the sporadic nature of AF. The Self-management and Educational technology support Tool for AF patients (SETAF) was designed based on the preferences and needs of AF patients but more study is required to assess the acceptance of this novel tool. Objective Explore the usability and acceptance of SETAF among AF patients in Singapore. Methods A mixed methods study was conducted with AF patients who were purposively sampled from an outpatient cardiology clinic in Singapore. After 6 weeks of using SETAF, semi-structured interviews were performed, and data were analyzed inductively following a thematic analysis approach. Results from a short 4-item survey and application usage data were also analyzed descriptively. Both qualitative and quantitative results were organized and presented following the Technology Acceptance Model (TAM) framework. Results A total of 37 patients participated in the study and 19 were interviewed. Participants perceived SETAF as useful for improving AF knowledge, self-management and access to healthcare providers and was easy to use due to the guided tutorial and user-friendly interface. They also identified the need for better personalization of content, psychosocial support features and reduction of language barriers. Application usage data revealed preference for AF related content and decreased interaction with the motivational message component of SETAF over time. Overall, most of the participants would continue using SETAF and were willing to pay for it. Conclusions AF patients in Singapore found SETAF useful and acceptable as a tool for AF management. The insights from this study not only support the potential of mHealth but may also inform the design and implementation of future mHealth tools for AF patients.

Abstract Background Shared decision making (SDM) is at the core of policy measures for making healthcare person-centred. However, the context-sensitive nature of the challenges in integrated stroke care calls for research to facilitate its implementation. This before and after evaluation study identifies factors for implementation and concludes with key recommendations for adoption. Methods Data were collected at the start and end of an implementation programme in five stroke services (December 2017 to July 2018). The SDM implementation programme consisted of training for healthcare professionals (HCPs), tailored support, development of decision aids and a social map of local stroke care. Participating HCPs were included in the evaluation study: A questionnaire was sent to 25 HCPs at baseline, followed by 11 in-depth interviews. Data analysis was based on theoretical models for implementation and 51 statements were formulated as a result. Finally, all HCPs were asked to validate and to quantify these statements and to formulate recommendations for further adoption. Results The majority of respondents said that training of all HCPs is essential. Feedback on consultation and peer observation are considered to help improve performance. In addition, HCPs stated that SDM should also be embedded in multidisciplinary meetings, whereas implementation in the organisation could be facilitated by appointed ambassadors. Time was not seen as an inhibiting factor. According to HCPs, negotiating patients’ treatment decisions improves adherence to therapy. Despite possible cognitive or communications issues, all are convinced patients with stroke can be involved in a SDM-process. Relatives play an important role too in the further adoption of SDM. HCPs provided eight recommendations for adoption of SDM in integrated stroke care. Conclusions HCPs in our study indicated it is feasible to implement SDM in integrated stroke care and several well-known implementation activities could improve SDM in stroke care. Special attention should be given to the following activities: (1) the appointment of knowledge brokers, (2) agreements between HCPs on roles and responsibilities for specific decision points in the integrated stroke care chain and (3) the timely investigation of patient’s preferences in the care process – preferably before starting treatment through discussions in a multidisciplinary meeting.

Introduction: In a previous rapid realist review (RRR), an initial programme theory (PT) was established giving insight into the interrelatedness of context items, mechanisms, programme-activities, and outcomes that influence integrated care programmes (ICPs) for community-dwelling frail older people. As ICPs need to be tailored to their local setting, the objective of this study is to assess consensus on the relevance of the items identified in the RRR for the Dutch setting, and refine the PT, where appropriate. Methods: A two-round e-Delphi study was carried out among Dutch experts to determine the relevance of 71 items. Results: Consensus on relevance was reached on 57 out of 71 items (80%). Items added to refine the PT included: increasing number of older people, decreasing access to hospital beds, well-designed ICP implementation processes, case management, having a clear portfolio of patients, the role of the government, aligning existing health and social care systems, management and monitoring of care activities, strong relationship between older person and healthcare providers (HCP), and providing continuous feedback to HCPs. Conclusion and discussion: The initial PT was refined for the Dutch setting. Items on which no consensus was found, need to be further investigated on the reason behind it.

Background: To help enhance the quality of integrated stroke care delivery, regional stroke services networks in the Netherlands participated in a self-assessment study in 2012, 2015 and 2019. Methods: Coordinators of the regional stroke services networks filled out an online self-assessment questionnaire in 2012, 2015 and 2019. The questionnaire, which was based on the Development Model for Integrated Care, consisted of 97 questions in nine clusters (themes). Cluster scores were calculated as proportions of the activities implemented. Associations between clusters and features of stroke services were assessed by regression analysis. Results: The response rate varied from 93.1% (2012) to 85.5% (2019). Over the years, the regional stroke services networks increased in ‘size’: the median number of organisations involved and the volume of patients per network increased (7 and 499 in 2019, compared to 5 and 364 in 2012). At the same time, fewer coordinators were appointed for more than 1 day a week in 2019 (35.1%) compared to 2012 (45.9%). Between 2012 and 2019, there were statistically significantly more elements implemented in four out of nine clusters: ‘Transparent entrepreneurship’ (MD = 18.0% F(1) = 10.693, p = 0.001), ‘Roles and tasks’ (MD = 14.0% F(1) = 9.255, p = 0.003), ‘Patient-centeredness’ (MD = 12.9% F(1) = 9.255, p = 0.003), and ‘Commitment’ (MD = 11.2%, F(1) = 4.982, p = 0.028). A statistically significant positive correlation was found for all clusters between implementation of activities and age of the network. In addition, the number of involved organisations is associated with better execution of implemented activities for ‘Transparent entrepreneurship’, ‘Result-focused learning’ and ‘Quality of care’. Conversely, there are small but negative associations between the volume of patients and implementation rates for ‘Interprofessional teamwork’ and ‘Patient-centredness’. Conclusion: This long-term analyses of stroke service development in the Netherlands, showed that between 2012 and 2019, integrated care activities within the regional stroke networks increased. Experience in collaboration between organisations within a network benefits the uptake of integrated care activities.

Abstract Background Despite the emphasis on holistic health promotion in community programs for older people, few studies explicitly consider how BioPsychoSocial (BPS) health elements are interconnected and function to improve Quality of Life (QoL). The Community for Successful Ageing (ComSA) program in Singapore focuses on Community Development (CD) initiatives for older people, accounting for BPS theory in its design and content. Biological (B) health is conceived as physiological and cognitive functioning and related biological self-care; Psychological (P) health as feelings of life satisfaction, and Social health (S) as perceived social support and civic engagement. Furthermore, three overlapping sub-constructs are theorized to connect these elements. Namely Bio-Psychological (BP) health in terms of self-perceptions of ageing; the Psycho-Social (PS) aspects of interpersonal communication; and the Socio-Communal (SC) health in terms of civic engagement. BPS health is conceived as distinct from QoL, defined as composed of control, autonomy, self-realisation and pleasure (measured by CASP-19) of the older person. We examined 1) interconnections of BPS constructs and related sub-constructs and 2) their associations with QoL to inform a practical, applied program theory. Methods A baseline survey (n = 321) of program participants (Mean = 70 years, SD = 8.73). All continuous variables were binarized as ‘high’ if the scores were above the median. Multivariate logistic regression was used to assess 1) the adjusted effect of each BPS construct on CASP-19, and 2) the odds of scoring high on one BPS construct with the odds of scoring high on a related sub-construct (e.g. B and BP health). Results The strongest relationship with QoL was markedly with BP self-perceptions of ageing (OR = 4.07, 95%CI = 2.21–7.49), followed by P life satisfaction (OR = 3.66, 95%CI = 2.04–6.57), PS interpersonal communication (OR = 2.42, 95%CI = 1.23–4.77), SC civic engagement (OR = 1.94, 95%CI = 1.05–3.57), and S social support (OR = 1.89, 95%CI = 1.06–3.38). Core B, P and S health were closely associated with their sub-constructs. Conclusion ComSA CD is tightly coupled to its proposed program theory. It offers classes to improve B self-care and BP self-perceptions of ageing, group-based guided autobiography to improve P life-satisfaction and PS interpersonal communication, and community initiatives that encourage seniors to solve community issues. This holistic approach is likely to enhance ageing experiences and QoL.

Abstract Background The Community for Successful Ageing (ComSA) program has implemented overlapping BioPsychoSocial (BPS) components as part of a Community Development (CD) grassroots and volunteer-led initiative. Implementation of such multi-component programming is influenced by known program characteristics including novelty, complexity and observability as well as related organizational factors. As such, we explored ComSA CD’s implementation from the organizational perspective, seeking to inform program improvements. Methods We conducted four focus groups with program staff, partners and trainers (total N = 21 participants). Findings were analysed using an interpretative approach and synthesized into a line of argument informing lessons learnt. Results An implementation framework was identified. It is guided by considering the influence of known program characteristics across major themes, representing three core implementation stages. These and supporting sub-themes are elaborated in turn: 1) Creating commitment toward the program was challenged by novelty and at times a lack of shared understanding of ComSA CD, particularly relating to the S component. Overall, cohesion within organizational contexts and having a strong rapport with the community (ability to engage) were needed to persuade volunteers and participants to commit to the program.2) Coordination and resource allocation were influenced by the complexity of interconnecting BPS components - requiring aligning communication between partners and adapting the BPS sequence, given the separated management structure of program trainers. Efficiency of resource utilization was constrained by the ability to pool and match resources given the limited manpower and community partners who worked-in-silo due to a KPI-centric culture.3) Collaborative program monitoring and appraisal increased observability of the program’s benefits, but depended on partners’ prior commitment. Despite appreciating its holistic BPS programming, dropout rate was used as a way to gauge program success, which has limited interpretability. Occasional uncertainty about the program value contributed to concerns about duplicating existing ageing programs, particularly those related to the B component. Conclusion Lessons learnt for improving BPS programming include (1) eliciting better participants’ buy-in and shared program vision, (2) increasing adaptability of BPS sequence and building a culture of shared values for working together (3) and developing comprehensive monitoring systems for program appraisal.

Abstract Background If technologies are to support aging in place, then it is important to develop fundamental knowledge on what causes stability and changes in the use of technologies by seniors. However, longitudinal studies on the long-term use of technologies that have been accepted into the home (i.e., post-implementation use) are very scarce. Many factors potentially could influence post-implementation use, including life events, age-related decline, changes in personal goal orientation, and various types of social influences. The aforementioned factors are likely to be interrelated, adding to the complexity. The goal of this study is to better understand changes and stability in the use of technologies by independent-living seniors, by using a dynamical systems theory approach. Methods A longitudinal qualitative field study was conducted involving home visits to 33 community-dwelling seniors in the Netherlands, on three occasions (2012–2014). Interviews were held on technology usage patterns, including reasons for stable, increased, declined and stopped use. Technologies were included if they required electric power in order to function, were intended to be used in or around the home, and could support activities of daily living, personal health or safety, mobility, communication, and physical activity. Thematic analysis was employed, using constant case comparison to better understand dynamics and interplay between factors. In total, 148 technology use patterns by 33 participants were analyzed. Results A core of six interrelated factors was closely linked to the frequency of technology use: emotional attachment, need compatibility, cues to use, proficiency to use, input of resources, and support. Additionally, disruptive forces (e.g., social influences, competition with alternative means, changes of personal needs) could induce change by affecting these six factors. Furthermore, long-term technology use was in some cases more resilient to disruption than in other cases. Findings were accumulated in a new framework: Dynamics In Technology Use by Seniors (DITUS). Conclusions Similar to aging, the use of technologies by older people is complex, dynamic and personal. Periods of stability and change both occur naturally. The DITUS framework can aid in understanding stability and instability of technology use, and in developing and implementing sustainable technological solutions for aging in place.

Abstract Background To cope with rising demand for healthcare services in Singapore, Regional Health Systems (RHS) comprising of health and social care providers across care settings were set up to integrate service delivery. Tasked with providing care for the western region, in 2012, the National University Health System (NUHS) – RHS developed a transitional care program for elderly patients with complex healthcare needs who consumed high levels of hospital resources. Through needs assessment, development of personalized care plans and care coordination, the program aimed to: (i) improve quality of care, (ii) reduce hospital utilization, and (iii) reduce healthcare-related costs. In this study, recognizing the need for process evaluation in conjunction with outcome evaluation, we aim to evaluate the implementation fidelity of the NUHS-RHS transitional care program to explain the outcomes of the program and to inform further development of (similar) programs. Methods Guided by the modified version of the Conceptual Framework for Implementation Fidelity (CFIF), adherence and moderating factors influencing implementation were assessed using non-participatory observations, reviews of medical records and program databases. Results Most (10 out of 14) components of the program were found to be implemented with low or moderate level of fidelity. The frequency or duration of the program components were observed to vary based on the needs of users, availability of care coordinators (CC) and their confidence. Variation in fidelity was influenced predominantly by: (1) complexity of the program, (2) extent of facilitation through guiding protocols, (3) facilitation of program implementation through CCs’ level of training and confidence, (4) evolving healthcare participant responsiveness, and (5) the context of suboptimal capability among community providers. Conclusion This is the first study to assess the context-specific implementation process of a transitional care program in the context of Southeast Asia. It provides important insights to facilitate further development and scaling up of transitional care programs within the NUHS-RHS and beyond. Our findings highlight the need for greater focus on engaging both healthcare providers and users, training CCs to equip them with the relevant skills required for their jobs, and building the capability of the community providers to implement such programs.

Abstract Background The Scaling Integrated Care in Context (SCIROCCO) tool has been developed to facilitate knowledge transfer and learning about the implementation and scaling-up of integrated care in European regions. To adequately test the functionality of the tool in assessing the maturity for integrated care within regions, this study evaluated its structural validity, internal consistency and convergent validity. Methods Exploratory factor analysis was used to investigate the structural validity of the 12-items of the SCIROCCO tool. Hereafter, the internal consistency was assessed by calculating Cronbach’s and ordinal alpha. The convergent validity was explored by testing 23 pre-hypothesized relationships between items of the SCIROCCO tool and items of an instrument measuring a similar construct. Results Factor analysis revealed a one-factor structure. Cronbach’s alpha of the overall instrument was 0.92, ordinal alpha was 0.94. Only 30.34% of the hypotheses for testing the convergent validity were met. Conclusion The one-factor structure is considered relevant in representing the structural validity of the SCIROCCO tool. The scale of the SCIROCCO tool shows good internal consistency. The tool (DMIC Quickscan) used to assess the convergent validity might measure a different aspect of integrated care than the SCIROCCO tool. Further research is needed to continue investigating the validity and reliability of the tool.

Social Sciences - Abstract
Geospatial-qualitative methods, which combine both observation and interpretative accounts during data collection through extended exposure and movement in place, have been increasingly used to explore “person–place” interactions and assess communities of place. Despite their increased use, there is a lack of reflexive discussion on how they differ in capturing person–place interactions and ways to combine them. Drawing on our experiences using three related methods—Photovoice, Walking through Spaces, and interactive Participatory Learning and Action exercise-led community focus groups—we compared the methodological advantages that each method brings to the construction of “place” and in exploring person–place interactions among the community of older adults living in a neighborhood of Singapore for a neighborhood assessment. We then illustrated how using a Focus–Expand–Compare approach for methodological triangulation can add value in generating greater depth and breadth of perspectives on a topic of interest explored for intervention development.
