Background and purpose: Automatic approaches are widely implemented to automate dose optimization in radiotherapy treatment planning. This study systematically investigates how to configure automatic planning in order to create the best possible plans. Materials and methods: Automatic plans were generated using protocol based automatic iterative optimization. Starting from a simple automation protocol which consisted of the constraints for targets and organs at risk (OAR), the performance of the automatic approach was evaluated in terms of target coverage, OAR sparing, conformity, beam complexity, and plan quality. More complex protocols were systematically explored to improve the quality of the automatic plans. The protocols could be improved by adding a dose goal on the outer 2 mm of the PTV, by setting goals on strategically chosen subparts of OARs, by adding goals for conformity, and by limiting the leaf motion. For prostate plans, development of an automated post-optimization procedure was required to achieve precise control over the dose distribution. Automatic and manually optimized plans were compared for 20 head and neck (H&N), 20 prostate, and 20 rectum cancer patients. Results: Based on simple automation protocols, the automatic optimizer was not always able to generate adequate treatment plans. For the improved final configurations for the three sites, the dose was lower in automatic plans compared to the manual plans in 12 out of 13 considered OARs. In blind tests, the automatic plans were preferred in 80% of cases. Conclusions: With adequate, advanced, protocols the automatic planning approach is able to create high-quality treatment plans.

Social learning is the process of exchanging and developing knowledge (including skills and experiences) through human interaction. This key planning process needs to be better understood, given the increase and variety of non-planners influencing planning processes. This article explores who learns what from whom through social learning in planning. We unpack social learning theoretically to be able to map it, and employ empirically-based storytelling to discuss its relevance to planning practice. We conclude that social learning can lead to positive and negative outcomes and provides a useful analytical lens to understand planning practices at the level of individuals.

Balancing processes of external contingency and internal P-O fit is amongst the challenges facing innovative HE institutions today. This multi-level case study presents findings from a research & development program targeted to investigate and improve organisational-, leadership- and employees’ capacities to design, select and develop the human capital necessary to meet the strategic demands. The R&D project is framed as a collective organisational learning strategy with continuous alternation of research, design, pilots and implementation activities. Work in progress till 2020. At present 25 strategic personnel plans are developed for degree programs and other organizational units, each of which is tailored to the strategic horizon and market of that specific organisational entity. Furthermore, instrumentation to run a strategic personnel planning process for knowledge institutions is developed transferable to other institutions. Finally, input is provided for the development of strategic HRM for career development & mobility, professionalisation, team development and resourcing strategy. https://www.hec2019.nl/108493/wiki/449361/programme-abstracts

This paper examines how a serious game approach could support a participatory planning process by bringing stakeholders together to discuss interventions that assist the development of sustainable urban tourism. A serious policy game was designed and played in six European cities by a total of 73 participants, reflecting a diverse array of tourism stakeholders. By observing in-game experiences, a pre- and post -game survey and short interviews six months after playing the game, the process and impact of the game was investigated. While it proved difficult to evaluate the value of a serious game approach, results demonstrate that enacting real-life policymaking in a serious game setting can enable stakeholders to come together, and become more aware of the issues and complexities involved with urban tourism planning. This suggests a serious game can be used to stimulate the uptake of academic insights in a playful manner. However, it should be remembered that a game is a tool and does not, in itself, lead to inclusive participatory policymaking and more sustainable urban tourism planning. Consequently, care needs to be taken to ensure inclusiveness and prevent marginalization or disempowerment both within game-design and the political formation of a wider participatory planning approach.

DOEL. Dit artikel beoogt een kritische analyse te geven van de manier waarop het begrip Evidence Based Practice in de literatuur doorgaans wordt ingevuld, waarna mogelijkheden worden geschetst de in het artikel geconstateerde bezwaren te ondervangen. METHODE. Er is literatuuronderzoek gedaan naar de manier waarop EBP in de literatuur wordt ingevuld. RESULTAAT. Hoewel in de literatuur met betrekking tot EBP wordt aangegeven dat het handelen van professionals gebaseerd zou moeten zijn op een integratie van wetenschappelijk onderzoek, klinische expertise en cliëntenvoorkeuren, krijgt de bron van het wetenschappelijk onderzoek de meeste nadruk. Binnen dit wetenschappelijk onderzoek wordt kwantitatief onderzoek bovendien doorgaans hoger gewaardeerd dan kwalitatief onderzoek. De andere kennisbronnen (deskundigheid van de cliënt en expertise van de verpleegkundige) die bij EBP worden onderscheiden, blijven veelal onderbelicht. DISCUSSIE EN CONCLUSIE. De manier waarop EBP meestal wordt ingevuld en geïmplementeerd brengt een aantal beperkingen met zich mee. Voorbeelden hiervan zijn de beperkte aandacht voor: de kern van het verplegen, de interactie tussen de cliënt en de verpleegkundige, de context of de cultuur waarin de zorgverlening plaatsvindt, het benutten van de ervaringsdeskundigheid van de cliënt en de expertise van de verpleegkundige zelf. In het artikel worden suggesties gegeven om deze beperkingen te ondervangen, zodat EBP inderdaad de integratie wordt van de verschillende kennisbronnen die in de literatuur worden onderscheiden en EBP met mogelijk meer succes kan worden geïmplementeerd.

BackgroundSpecialist palliative care teams are consulted during hospital admission for advice on complex palliative care. These consultations need to be timely to prevent symptom burden and maintain quality of life. Insight into specialist palliative care teams may help improve the outcomes of palliative care.MethodsIn this retrospective observational study, we analyzed qualitative and quantitative data of palliative care consultations in a six-month period (2017 or 2018) in four general hospitals in the northwestern part of the Netherlands. Data were obtained from electronic medical records.ResultsWe extracted data from 336 consultations. The most common diagnoses were cancer (54.8%) and organ failure (26.8%). The estimated life expectancy was less than three months for 52.3% of all patients. Within two weeks after consultation, 53.2% of the patients died, and the median time until death was 11 days (range 191) after consultation. Most patients died in hospital (49.4%) but only 7.5% preferred to die in hospital. Consultations were mostly requested for advance care planning (31.6%). End-of-life preferences focused on last wishes and maintaining quality of life.ConclusionThis study provides detailed insight into consultations of palliative care teams and shows that even though most palliative care consultations were requested for advance care planning, consultations focus on end-of-life care and are more crisis-oriented than prevention-oriented. Death often occurs too quickly after consultation for end-of-life preferences to be met and these preferences tend to focus on dying. Educating healthcare professionals on when to initiate advance care planning would promote a more prevention-oriented approach. Defining factors that indicate the need for timely palliative care team consultation and advance care planning could help timely identification and consultation.

Aims and objectives: To describe the process of implementing evidence-based practice (EBP) in a clinical nursing setting. Background: EBP has become a major issue in nursing, it is insufficiently integrated in daily practice and its implementation is complex. Design: Participatory action research. Method: The main participants were nurses working in a lung unit of a rural hospital. A multi-method process of data collection was used during the observing, reflecting, planning and acting phases. Data were continuously gathered during a 24-month period from 2010 to 2012, and analysed using an interpretive constant comparative approach. Patients were consulted to incorporate their perspective. Results: A best-practice mode of working was prevalent on the ward. The main barriers to the implementation of EBP were that nurses had little knowledge of EBP and a rather negative attitude towards it, and that their English reading proficiency was poor. The main facilitators were that nurses wanted to deliver high-quality care and were enthusiastic and open to innovation. Implementation strategies included a tailored interactive outreach training and the development and implementation of an evidence-based discharge protocol. The academic model of EBP was adapted. Nurses worked according to the EBP discharge protocol but barely recorded their activities. Nurses favourably evaluated the participatory action research process. Conclusions: Action research provides an opportunity to empower nurses and to tailor EBP to the practice context. Applying and implementing EBP is difficult for front-line nurses with limited EBP competencies. Relevance to clinical practice: Adaptation of the academic model of EBP to a more pragmatic approach seems necessary to introduce EBP into clinical practice. The use of scientific evidence can be facilitated by using pre-appraised evidence. For clinical practice, it seems relevant to integrate scientific evidence with clinical expertise and patient values in nurses’ clinical decision making at the individual patient level.

Academic design research often fails to contribute to design practice. This dissertation explores how design research collaborations can provide knowledge that design professionals will use in practice. The research shows that design professionals are not addressed as an important audience between the many audiences of collaborative research projects. The research provides insight in the learning process by design professionals in design research collaborations and it identifies opportunities for even more learning. It shows that design professionals can learn about more than designing, but also about application domains or project organization.
