    Abstract Owing to increasing healthcare costs, there is a need to examine whether the benefits of new technologies are worth the extra cost. In proton therapy, where the evidence in favor is limited, it is heavily debated whether the expected benefit justifies the higher capital and operating costs. The aim of this article was to explore the existing methodologies of economic evaluations (EEs) of particle therapy and recommend an approach for future data collection and analysis. We reviewed the published literature on health economics of proton therapy using accepted guidelines on performing EE. Different cost strategies were assessed and comparisons with other treatment modalities were made in terms of cost-effectiveness. Potential bias in the existing studies was identified and new methodologies proposed. The principal cause of bias in EEs of proton therapy is the lack of valid data on effects as well as costs. The introduction of proton therapy may be seriously hampered by the lack of outcome and cost data and the situation is likely to continue not only in terms of justifying the capital investment but also covering the operational costs. We identified an urgent need to collect appropriate data to allow for reimbursement of such novel technology. In the absence of level 1 evidence, well-performed modeling studies taking into account the available cost and outcome parameters, including the current uncertainties, can help to address the problem of limited outcome and health economic data. The approach of coverage with evidence development, in which evidence is collected in an ongoing manner in population-based registries along with dedicated financing, may allow technological advances with limited initial evidence of benefit and value, such as protons, to become available to patients in an early phase of their technology life cycle.

    Abstract Surgical resection is considered the primary treatment modality for most histologies of brain tumors. However, the difficulty in achieving complete removal of skull base tumors, frequently affecting the brainstem and cranial nerves, led to the introduction of radiotherapy (RT). Today, postoperative RT is established as a standard modality. By using conventional radiation techniques with photons, optimal sparing of surrounding organs at risk appears to not always be possible, resulting in a limited tumor dose prescription and, consequently, an unsatisfactory local tumor control. A more advanced RT technology, particle therapy (PT)—such as protons and carbon ions—offers the potential of both physical (protons and ions) and biological (ions) advantages. Theoretically, the use of particle therapy is able to reduce the dose to the brainstem and allow dose escalation to the primary tumor with the hope of improving tumor control and survival. Results of several systematic literature reviews showed that level 1 evidence on the clinical efficacy of PT was lacking. However, in cases of skull base chordomas, treatment results of proton, as well as carbon ion, seem superior to photons. Despite the limited evidence-based results, as found in several reviews, and the high investment costs, particle therapy centers are being set up all over the world, with more than 20 new facilities currently either at the planning stage or already under development at various sites around the world. This proliferation reflects the continuing interest in particle therapy as a means of improving the therapeutic ratio in radiation oncology. The technologies used for developing and delivering particle therapy are expensive and require highly trained personnel. We do not yet know whether, overall, any improvements in clinical results achieved with particle therapy are sufficient to warrant such an extensive investment of time and money. In this lecture, current published data will be discussed, along with the relevance of proton and ion therapies in the treatment of skull base tumors.

    Abstract Purpose: To realize individualized safe radiation therapy, reliable treatment equipment is essential in combination with a system-level improvement approach. We hypothesized that implementation of a system that integrated all required treatment equipment would result in improved safety and stability of the irradiation treatment process.
    Methods and materials: Seven accelerators, portal imaging, and the treatment planning software were replaced by an integrated system that included 6 accelerators. The number of reported safety incidents and root causes were recorded between 2010 and 2014. Time series analysis was performed, and quantitative results were explored by structured interviews. Additionally, downtime was recorded.
    Results: From January 2010 to July 2014, 5085 incidents were reported. Reports related to the accelerators decreased from 33% (2010) to 20% (2013-2014) of total reports, whereas the number of delivered fractions per accelerator increased by 20% (2010: 643 per month; 2013: 795 per month). Reports related to portal imaging decreased from 16.5 reports per month (2010) to 3.1 (2013-2014). Of these portal imaging reports, 316 had at least 1 technical cause in 2010, which decreased to 13 in 2013-2014. Interviewees attributed the decreased reporting to the equipment transition, not to decreased safety awareness. Downtime decreased by 46%, from 5.4% in 2010 to 2.9% in 2013.
    Conclusions: The number of reported accelerator- and portal imaging-related incidents decreased significantly, whereas safety awareness remained stable. In addition, accelerator downtime decreased, possibly resulting in less rescheduling of patients and fewer disruptions of work processes. Therefore, we conclude that the risk for serious safety incidents and patient harm decreased after implementation of the new integrated system.

    Abstract Purpose: For change programs to succeed, it is vital to have a detailed understanding of employees' views regarding the program, especially when the proposed changes are potentially contested. Gaining insight into employee perceptions helps managers to decide how to proceed. The authors conducted two workshops in a radiotherapy institute to assess the benefits and drawbacks, as well as their underlying causes, of a proposed Lean change program. Managers' views on the workshops' usefulness were charted. The paper aims to discuss these issues.
    Design/methodology/approach: Two workshops were organized in which employees predicted positive and negative effects of a Lean program. The workshops combined a structured brainstorm (KJ-technique) and an evaluation of the expected effects. Eight top managers judged the workshops' value on supporting decision making.
    Findings: In total, 15 employees participated in the workshops. Participants from workshop 2 reported more expected effects (27 effects; 18 positive) than from workshop 1 (14 effects; six positive). However, when effects were categorized, similar results were shown. Three from eight managers scored the results relevant for decision making and four neutral. Seven managers recommended future use of the instrument. Increased employee involvement and bottom-up thinking combined with relatively low costs were appreciated most.
    Practical implications: The workshop could serve as a simple instrument to improve decision making and enhance successful implementation of change programs, as it was expected to enhance employees' involvement and was relatively easy to conduct and cheap.
    Originality/value: The workshop increased insight into employee views, facilitating adaptive actions by healthcare organization managers.

    Abstract Proton beam therapy provides the opportunity for more localized delivery of ionizing radiation with the potential for improved normal tissue avoidance to reduce treatment related morbidity and to allow for dose escalation to improve disease control and survival without increased toxicity. However, a systematic review of published peer-reviewed literature reported previously and updated here is devoid of any clinical data demonstrating benefit in terms of survival, tumor control, or toxicity in comparison with best conventional treatment for any of the tumors so far treated including skull base and ocular tumors, prostate cancer and childhood malignancies. The current lack of evidence for benefit of protons should provide a stimulus for continued research. Well designed in silico clinical trials using validated normal tissue complication probability-models are important to predict the magnitude of benefit for individual tumor sites but the future use of protons should be guided by clear evidence of benefit demonstrated in well-designed prospective studies, away from commercial influence, and this is likely to require international collaboration. Any complex and expensive technology, including proton therapy, should not be employed on the basis of belief alone and requires testing to avoid inappropriate use of potential detriment to future patients.

    Abstract Purpose: Questions are being raised regarding the cost of particle therapy (PT), and with them criticism that PT is too expensive to allow the expected gain in effectiveness. This paper aims to get more insight in the cost and cost-effectiveness of particle therapy and to discuss a future strategy that allows for critical assessment of this health technology.
    Material and methods: A systematic literature review based on an earlier published comprehensive review was performed and updated until June 1st 2008. Besides, current business plans of PT projects were examined. Additionally, results retrieved from a cost-simulation tool developed under auspice of the ENLIGHT were discussed.
    Results: The current literature on cost-effectiveness of PT is scarce, non-comparable, and largely not performed according to standard health technology assessment criteria. Besides, different perspectives for cost evaluations have been used, making it difficult to compare and to determine the relative impact in terms of costs for this new treatment modality.
    Conclusions: Evidence on the cost-effectiveness of PT is scarce. Adequate reimbursement is necessary to support such innovative yet costly treatments. For now, model-based economic evaluations performed at least from a health care perspective may help us to gain evidence-based insight into cost-effectiveness.

    Abstract Objectives: To realize safe, high-quality treatment, employees should behave according to patient safety standards. Periodic measurement of safety behavior could provide management-relevant information to adjust the implementation of interventions and maximize improvement. Therefore, we constructed a factorial survey measuring safety awareness and intentions for behavior.
    Methods: Cross-sectional results of the factorial survey were compared with results from the Hospital Survey on Patient Safety Culture, distributed in MAASTRO radiotherapy in 2010 to 2011. Respondents were presented 20 scenarios about incidents, randomly varying on work pressure, person causing incident, whether patient level was reached, severity of harm, notification by patient, and management support. After each scenario, questions were asked about safety awareness and behavior. χ and multilevel regression analyses were used.
    Results: Response rates were 64% (n = 54) for the culture survey and 62% (n = 52) for the factorial survey on intentions. The culture survey reflected positive opinions regarding nonpunitive response and incident reporting, in accordance with high scores (factorial survey) on safety awareness (9.0; scale, 1-10) and reporting intentions (8.7). Whether an incident reached the patient level predicted safety awareness and intentions for safety behavior (β = -1.3/-3.08) most strongly. Severity of harm showed minimal additional effects (β = -0.24/-0.42).
    Conclusions: The factorial survey presented practical information on safety awareness and intentions for behavior. Therefore, it created additional opportunities for improving safety interventions. Because behavior is expected to change before values, one could hypothesize that factorial surveys would be more sensitive to change than culture surveys. Longitudinal research should further study the surveys' sensitivity to measure changes.

    Abstract Purpose: The importance of a safety culture to maximize safety is no longer questioned. However, achieving sustainable culture improvements are less evident. Evidence is growing for a multifaceted approach, where multiple safety interventions are combined. Lean management is such an integral approach to improve safety, quality and efficiency and therefore, could be expected to improve the safety culture. This paper presents the effects of lean management activities on the patient safety culture in a radiotherapy institute.
    Methods: Patient safety culture was evaluated over a three year period using triangulation of methodologies. Two surveys were distributed three times, workshops were performed twice, data from an incident reporting system (IRS) was monitored and results were explored using structured interviews with professionals. Averages, chi-square, logistical and multi-level regression were used for analysis.
    Results: The workshops showed no changes in safety culture, whereas the surveys showed improvements on six out of twelve dimensions of safety climate. The intention to report incidents not reaching patient-level decreased in accordance with the decreasing number of reports in the IRS. However, the intention to take action in order to prevent future incidents improved (factorial survey presented β: 1.19 with p: 0.01).
    Conclusions: Due to increased problem solving and improvements in equipment, the number of incidents decreased. Although the intention to report incidents not reaching patient-level decreased, employees experienced sustained safety awareness and an increased intention to structurally improve. The patient safety culture improved due to the lean activities combined with an organizational restructure, and actual patient safety outcomes might have improved as well.
