    Three retrogressive thaw slumps of varying age have been initiated by erosion of ice-rich glaciolacustrine sediments on a bend of Stewart River, 3 km upstream from Mayo, Yukon Territory. Two of the slumps are presently active; the third stabilized before 1944. The rate of retreat of the active slump headwalls between 1949 and 1987, determined from aerial photographs and ground surveys, is up to 16 m/yr. Floors of the active thaw slumps contain well-defined vegetation successional communities that are distinct from the local, mature boreal forest. Although a few clumps of mature forest vegetation survive the fall into the slump, a birch/white spruce sere, similar to the original forest, is re-established after a period of 35-50 years. Changes in soil calcium carbonate and soil structure profiles on disturbed surfaces of varying age demonstrate the initiation of pedogenesis in the floor of the stabilized slump, but assays of pH, orgainic carbon and total nitrogen indicate that after about 40 years the new soils remain immature. Comparison of ground temperatures in the stabilized thaw slump and at undisturbed sites in the area indicates that the ground thermal regime may return to local conditions a century or more after disturbance.Key words: permafrost, terrain disturbance, retrogressive thaw slump, vegetation succession, Yukon TerritoryMots clés: pergélisol, perturbation du terrain, décrochement de fonte régressif, succession végétale, territoire du Yuko

    Openheid over medische fouten: waar staan we?

    ā€¢Recente, breed gedragen richtlijnen bepalen dat artsen en andere zorgverleners open en eerlijk behoren te zijn over incidenten, dat wil zeggen: medische fouten. ā€¢Deze norm wordt versterkt door uitspraken van het tuchtcollege en zal naar verwachting binnenkort ook wettelijk geregeld worden. ā€¢In de praktijk is er nog sprake van tal van persoonlijke en institutionele belemmeringen bij het communiceren over incidenten. ā€¢De elders ontwikkelde open benadering (ā€˜open disclosureā€™-benadering) kan ook in Nederland behulpzaam zijn bij het wegnemen van die belemmeringen.

    Validation of the Protect Questionnaire: A tool to detect mental health problems in asylum seekers by non-health professionals

    Get PDF
    Introduction: Prevalence rates of trauma-related mental disorders such as posttraumatic stress disorder (PTSD) or major depression (MD) are high in asylum seekers. The PROTECT Questionnaire (PQ) was designed to detect indications of those disorders in asylum seekers. Empirical data are needed to evaluate the PQ psychometrically. The objective of this study is to investigate the reliability, validity, sensitivity, and specificity of the PQ. Method: The PQ and validated questionnaires for PTSD (Posttraumatic Diagnostic Scale, PDS) and depression (Patient Health Questionnaire-9, PHQ- 9) were filled in by a sample of recently arrived asylum seekers in Germany (n=141). A sub-sample of 91 asylum seekers took part in a structured clinical interview to diagnose PTSD or MD (SCID-I). Results: The PQ showed a one-factor structure and good reliability (Cronbachā€™s āŗ= .82). It correlated highly with the PDS and the PHQ-9 (rs=.53-.77; psā‰¤.001). Diagnostic accuracy with regard to PTSD (AUC=.74; SE=.06; p<.001; 95%-CI=.63-.84) and MD (AUC=.72; SE=.06; p<.001; 95%-CI=.61- .83) was adequate, suggesting an optimal cut-off of 8 or 9. By categorizing participants into a low- and high-risk category, the PQ differentiated well between asylum seekers who fulfilled a PTSD or MD diagnosis and those who did not. Discussion: The results support the use of the PQ as a reliable and valid instrument for the purpose of detecting signs and symptoms of the two most common mental disorders in asylum seekers. Persons found to be at risk of mental disorders should be referred to a clinical diagnostic procedure

    Why patients may not exercise their choice when referred for hospital care:An exploratory study based on interviews with patients

    Get PDF
    Background Various north-western European health-care systems encourage patients to make an active choice of health-care provider. This study explores, qualitatively, patients' hospital selection processes and provides insight into the reasons why patients do or do not make active choices. Methods Semi-structured individual interviews were conducted with 142 patients in two departments of three Dutch hospitals. Interviews were recorded, transcribed and analysed in accordance with the grounded theory approach. Results Three levels of choice activation were identified ā€“ passive, semi-active and active. The majority of the patients, however, visited the default hospital without having used quality information or considered alternatives. Various factors relating to patient, provider and health-care system characteristics were identified that influenced patients' level of choice activation. On the whole, the patients interviewed could be classified into five types with regard to how they chose, or ā€˜ended up atā€™ a hospital. These types varied from patients who did not have a choice to patients who made an active choice. Conclusions A large variation exists in the way patients choose a hospital. However, most patients tend to visit the default without being concerned about choice. Generally, they do not see any reason to choose another hospital. In addition, barriers exist to making choices. The idea of a patient who actively makes a choice originates from neoclassical microeconomic theory. However, policy makers may try in vain to bring principles originating from this theory into health care. Even so, patients do value the opportunity of attending ā€˜theirā€™ own hospital

    The impact of ex-post legislative evaluations in healthcare:A mixed methods realist evaluation study protocol for conducting case studies

    Get PDF
    Background:Recent studies on the impact of ex-post legislative evaluations show that there are different types of impact and different factors that can influence it. These include the context of a legislative evaluation, research quality, and interactions between researchers and other actors within the evaluation process. However, thorough empirical research in this area is lacking. This warrants empirical research into the factors that influence the impact of ex-post legislative evaluations, so these insights can be used to increase the likelihood of ex-post legislative evaluations having an impact.Methods and analysis:In this protocol, we report on the realist evaluation methodology that will be used to evaluate the impact of three ex-post legislative evaluations in the Dutch healthcare sector. The mixed methods realist evaluation approach will facilitate this theory-driven, qualitative research. The study will consist of the following three steps: (1) Initial programme theory development, (2) theory validation, and (3) theory refinement. Knowledge from two scoping reviews conducted previously, and two subsequent expert meetings will form the basis for developing the initial programme theory. During this study, three case studies will be conducted, in which three individual ex-post legislative evaluations will be examined. Specific methods for data collection will include: documentary review, observation, structured questionnaires and focus group discussions with purposefully identified key stakeholders. Using the framework approach, the data will be analysed thematically in a within-case analysis followed by across-case analysis. Discussion:This protocol provides insight into how the study will be conducted. As this study uses multiple qualitative research methods to answer one question, this protocol supports refining data collection procedures. Careful consideration of the approach beforehand can minimise pitfalls, reduce publication bias and improve reproducibility. The protocol therefore specifies how the research question will be answered in detail, and this provides solid guidance for the research process

    Medical dispute committees in the Netherlands:A qualitative study of patient expectations and experiences

    Get PDF
    BACKGROUND: Health care incidents, such as medical errors, cause tragedies all over the world. Recent legislation in the Netherlands has established medical dispute committees to provide for an appeals procedure offering an alternative to civil litigation and to meet the needs of clients. Dispute committees incorporate a hybrid procedure where one can file a complaint and a claim for damages resulting in a verdict without going to court. The procedure is at the crossroads of complaints law and civil litigation. This study seeks to analyze to what extent patients and family members' expectations and experiences with dispute committees match the goals of the new legislation. METHODS: This qualitative, retrospective research includes in-depth, semi-structured, face-to-face interviews with patients or family members who filed a complaint with a dispute committee in the Netherlands. The researchers conducted an inductive, thematic analysis of the qualitative data. RESULTS: A total of 26 interviews were held with 30 patients and family members. The results showed that participants particularly felt the need to be heard and to make a positive impact on health care. Some wished to be financially compensated, for others money was the last thing on their mind. The results demonstrated the existence of unequal power relationships between participants and both the defendant and dispute committee members. Participants reported the added value of (legal) support and expressed the need for dialogue at the hearing. Participants sometimes experienced closure after the proceedings, but often did not feel heard or felt a lack of a practical outcome and a tangible improvement. CONCLUSIONS: This study shows that participants' expectations and experiences were not always met by the current set up of the dispute committee proceedings. Participants did not feel heard, while they did value the potential for monetary compensation. In addition, some participants did not experience an empowered position but rather a feeling of a power misbalance. The feeling of a power misbalance and not being heard might be explained by existing epistemic injustice, which is a concept that should be carefully considered in processes after health care incidents

    Is there a mismatch between the perspectives of patients and regulators on healthcare quality?:A survey study

    Get PDF
    Objectives: Internationally, healthcare quality regulators are criticized for failing to respond to patients' complaints. Patient involvement is, therefore, an important item on the policy agenda. However, it can be argued that there is a discrepancy between the patients' perspective and current regulatory approaches. This study examines whether a discrepancy exists between the perspectives of patients and regulators on healthcare quality. Methods: A questionnaire was sent to 996 people who had registered a complaint with the Dutch Healthcare Inspectorate to measure expectations of and experiences with the Inspectorate. A taxonomy was used to classify their complaints into the clinical, relationship, or management domains. Results: The response was 54%. More complaints about clinical issues (56%, P = 0.000) were investigated by the regulator than complaints about organizational (37%) and relational issues (51%). Patients with complaints about management issues less often indicated (13%, P = 0.002) that healthcare is improved by making their complaint than patients with complaints about clinical or relationship issues did (22%ā€“23%). Patients who reported about relational issues with care providers attached more importance to issuing sanctions against the care provider than other patients (mean score 2.89 versus 2.62ā€“2.68, P = 0.006). Conclusions: The predominant clinical approach taken by regulators does not match the patients' perspective of what is relevant for healthcare quality. In addition, patients seem to be more tolerant of what they perceive to be clinical or management errors than of perceived relational deficiencies in care providers. If regulators want to give patients a voice, they should expand their horizon beyond the medical framework

    Recording of weight in electronic health records:An observational study in general practice

    Get PDF
    Background Routine weight recording in electronic health records (EHRs) could assist general practitioners (GPs) in the identification, prevention, and management of overweight patients. However, the extent to which weight management is embedded in general practice in the Netherlands has not been investigated. The purpose of this study was to evaluate the frequency of weight recording in general practice in the Netherlands for patients who self-reported as being overweight. The specific objectives of this study were to assess whether weight recording varied according to patient characteristics, and to determine the frequency of weight recording over time for patients with and without a chronic condition related to being overweight. Methods Baseline data from the Occupational and Environmental Health Cohort Study (2012) were combined with data from EHRs of general practices (2012ā€“2015). Data concerned 3446 self-reported overweight patients who visited their GP in 2012, and 1516 patients who visited their GP every year between 2012 and 2015. Logistic multilevel regression analyses were performed to identify associations between patient characteristics and weight recording. Results In 2012, weight was recorded in the EHRs of a quarter of patients who self-reported as being overweight. Greater age, lower education level, higher self-reported body mass index, and the presence of diabetes mellitus, chronic obstructive pulmonary disease, and/or cardiovascular disorders were associated with higher rates of weight recording. The strongest association was found for diabetes mellitus (adjusted ORā€‰=ā€‰10.3; 95% CI [7.3, 14.5]). Between 2012 and 2015, 90% of patients with diabetes mellitus had at least one weight measurement recorded in their EHR. In the group of patients without a chronic condition related to being overweight, this percentage was 33%. Conclusions Weight was frequently recorded for overweight patients with a chronic condition, for whom regular weight measurement is recommended in clinical guidelines, and for which weight recording is a performance indicator as part of the payment system. For younger patients and those without a chronic condition related to being overweight, weight was less frequently recorded. For these patients, routine recording of weight in EHRs deserves more attention, with the aim to support early recognition and treatment of overweight

    Factors influencing the impact of ex-post legislative evaluations:A scoping review

    Get PDF
    This article explores the factors that influence the impact of ex-post legislativeevaluations and suggests that these factors can be divided into three maincategories: context, research quality, and interaction. Contextual factors,including the evaluationā€™s initiation, itā€™s place in the legislative process, thevaried functions given by stakeholders, and the level of political or socialattention, are beyond researchersā€™ control. However, researchers caninfluence research quality and interaction with stakeholders, such as theevaluationsā€™ commissioner, as well as the society at large, thereby increasingthe likelihood of achieving impactful results. They should engage with theevaluation context to improve impact, but must also maintain independencewhile being influenced by the context. These findings are in line with themuch broader literature on the impact of policy and programme evaluationswhich pays less attention to the policy instrument legislation. Therefore, bothdisciplines have an interest in a better exchange of knowledge
