Stable gonality is computable

Stable gonality is a multigraph parameter that measures the complexity of a graph. It is defined using maps to trees. Those maps, in some sense, divide the edges equally over the edges of the tree; stable gonality asks for the map with the minimum number of edges mapped to each edge of the tree. This parameter is related to treewidth, but unlike treewidth, it distinguishes multigraphs from their underlying simple graphs. Stable gonality is relevant for problems in number theory. In this paper, we show that deciding whether the stable gonality of a given graph is at most a given integer $k$ belongs to the class NP, and we give an algorithm that computes the stable gonality of a graph in $O((1.33n)^nm^m \text{poly}(n,m))$ time.Comment: 15 pages; v2 minor changes; v3 minor change

Early identification of and proactive palliative care for patients in general practice, incentive and methods of a randomized controlled trial

BACKGROUND According to the Word Health Organization, patients who can benefit from palliative care should be identified earlier to enable proactive palliative care. Up to now, this is not common practice and has hardly been addressed in scientific literature. Still, palliative care is limited to the terminal phase and restricted to patients with cancer. Therefore, we trained general practitioners (GPs) in identifying palliative patients in an earlier phase of their disease trajectory and in delivering structured proactive palliative care. The aim of our study is to determine if this training, in combination with consulting an expert in palliative care regarding each palliative patient's tailored care plan, can improve different aspects of the quality of the remaining life of patients with severe chronic diseases such as chronic obstructive pulmonary disease, congestive heart failure and cancer. METHODS/DESIGN A two-armed randomized controlled trial was performed. As outcome variables we studied: place of death, number of hospital admissions and number of GP out of hours contacts. DISCUSSION We expect that this study will increase the number of identified palliative care patients and improve different aspects of quality of palliative care. This is of importance to improve palliative care for patients with COPD, CHF and cancer and their informal caregivers, and to empower the GP. The study protocol is described and possible strengths and weaknesses and possible consequences have been outlined. TRIAL REGISTRATION The Netherlands National Trial Register: NTR2815

A critical analysis of scales to measure the attitude of nurses toward spiritual care and the frequency of spiritual nursing care activities

Quantitative studies have assessed nurses' attitudes toward and frequency of spiritual care [SC] and which factors are of influence on this attitude and frequency. However, we had doubts about the construct validity of the scales used in these studies. Our objective was to evaluate scales measuring nursing SC. Articles about the development and psychometric evaluation of SC scales have been identified, using, Web of Science, and CINAHL, and evaluated with respect to the psychometric properties and item content of the scales. Item content was evaluated by each of the five authors with respect to the following questions: Does the item (1) reflect a general opinion about SC instead of a personal willingness to offer SC; (2) reflect general psychosocial care instead of specific SC; (3) focus solely on religious care; (4) contain the words 'spiritual' (care/needs/health/strengths, etc.); and (5) contain multiple propositions, or have an unclear meaning? We found eight scales. Psychometric analysis of these scales was often meager and the items of all but one scale suffered from two or more of the five problems described above. This leads us to conclude that many quantitative results in this area are based on findings with questionable scales. Suggestions for improvements are provided

An e-learning supported Train-the-Trainer program to implement a suicide practice guideline. Rationale, content and dissemination in Dutch mental health care

AbstractAn e-learning supported Train-the-Trainer program was developed to implement the Dutch suicide practice guideline in mental health care. Literature on implementation strategies has been restricted to the final reporting of studies with little opportunity to describe relevant contextual, developmental and supporting work that would allow for a better interpretation of results and enhance the likelihood of successful replication of interventions. Therefore, in this paper we describe the theoretical and empirical background, the material and practical starting points of the program. We monitored the number of professionals that were trained during and after a cluster randomized trial in which the effects of the program have been examined.Each element of the intervention (Train-the-Trainer element, one day face-to-face training, e-learning) is described in detail. During the trial, 518 professionals were trained by 37 trainers. After the trial over 5000 professionals and 180 gatekeepers were trained. The e-learning module for trainees is currently being implemented among 30 mental health care institutions in The Netherlands.These results suggest that an e-learning supported Train-the-Trainer program is an efficient way to uptake new interventions by professionals. The face-to-face training was easily replicable so it was easy to adhere to the training protocol. E-learning made the distribution of the training material more viable, although the distribution was limited by problems with ICT facilities. Overall, the intervention was well received by both trainers and trainees. By thoroughly describing the material and by offering all training materials online, we aim at further dissemination of the program

Timely identification of palliative patients and anticipatory care planning by GPs: practical application of tools and a training programme

Contains fulltext : 171812.pdf (publisher's version ) (Open Access)BACKGROUND: Palliative care is mainly restricted to terminal care. General practitioners (GPs) are not trained to early identify palliative patients with cancer, COPD or heart failure. With the help of the RADboud indicators for PAlliative Care needs (RADPAC), we trained GPs to identify patients' needs and to make a proactive care plan. They were also able to join two role-plays where they discussed the patient's future, and consulted a palliative care consultant to fine-tune the care plan. We evaluated the programme with the GPs and consultants and noted its impact on their daily practice. METHODS: Two years after they had participated in the programme, we held semi-structured interviews with the GPs and a focus group interview with the consultants and performed a thematic content analysis. RESULTS: Six consultants and nine GPs participated in the programme. Most GPs and consultants mentioned positive changes in the thinking or acting of GPs regarding early palliative care. A number continued to use the tool to identify patients; most of the others noted they had internalised the indicators. Although half of them still considered discussing end-of-life aspects difficult, particularly in patients with organ failure, the others were more easily able to discuss the future with their palliative patients. CONCLUSION: Although most GPs and consultants were positive about the training programme and applying it in daily practice, we conclude that in future programmes, more attention needs to paid to timely identification of palliative patients with COPD or CHF and how to discuss the future with them
