The long-term success of metabolic and bariatric surgery (MBS) depends largely on adherence to health-promoting behaviour following MBS. Especially, adherence to healthy dietary behaviour in line with guidelines appears to be of the utmost importance. The primary objective of the present study is to evaluate the effect of adherence to dietary behaviour recommendations and the percentage of total weight loss (%TWL) after MBS. Adherence is hypothesised to have a positive influence on the %TWL, 24 months after MBS. Furthermore, we investigate the association of various sociodemographic, organisational, psychological and behavioural factors prior to and after MBS and their effect on %TWL.

The present study is a single-centre observational, prospective, longitudinal cohort study conducted in Germany. Data are collected at nine measurement points (T0: 4 weeks prior to MBS; T1: 2 weeks after MBS, T2: 5 weeks after MBS; T3: 3 months after MBS; T4: 6 months after MBS; T5: 12 months after MBS; T6: 18 months after MBS; T7: 24 months after MBS; and T8: 36 months after MBS). Adherence to dietary behaviour recommendations is assessed using the Dietary Behavior Inventory-Surgery (DBI-S). N=325 patients applying for MBS will be included in the study. A regression analysis approach is chosen to answer the primary research question. The primary outcome %TWL is regressed at T7 (24 months after MBS) in a causal analysis on dietary adherence (DBI-S score) at T3–T7, with the covariates age, gender, marital status, educational attainment, employment status, Patient Health Questionnaire-4 score and body mass index at T0 and MBS method at T1. Stepwise hierarchical regression analyses are performed and analysed for significant model differences using ² difference tests. Effect sizes are estimated by R². Group differences are analysed using t-tests and Analyses of variance (ANOVAs). Bivariate correlations of continuous variables are examined using regression/correlation analyses.

The Ethics Committee of the Medical Faculty of the University of Essen-Duisburg has approved the conduct of the study (24-11969-BO). Results will be disseminated through manuscripts in clinical/academic peer-reviewed journals, presentations at academic conferences and communications with partners, participants and other stakeholders. Key findings will also be published in lay language on a publicly accessible website and disseminated via various (social) media channels.

The study has been prospectively registered on 8 October 2024 in the German Clinical Trials Register (DRKS00034888).

Communication skills assessment (CSA) is essential for ensuring competency, guiding educational practices and safeguarding regulatory compliance in health professions education (HPE). However, there appears to be heterogeneity in the reporting of validity evidence from CSA methods across the health profession that complicates our interpretation of the quality of assessment methods. Our objective was to map reliability and validity evidence from scores of CSA methods that have been reported in HPE.

Scoping review.

MEDLINE, Embase, PsycINFO, CINAHL, ERIC, CAB Abstracts and Scopus databases were searched up to March 2024.

We included studies, available in English, that reported validity evidence (content-related, internal structure, relationship with other variables, response processes and consequences) for CSA methods in HPE. There were no restrictions related to date of publication.

Two independent reviewers completed data extraction and assessed study quality using the Medical Education Research Study Quality Instrument. Data were reported using descriptive analysis (mean, median, range).

A total of 146 eligible studies were identified, including 98 394 participants. Most studies were conducted in human medicine (124 studies) and participants were mostly undergraduate students (85 studies). Performance-based, simulated, inperson CSA was most prevalent, comprising 115 studies, of which 68 studies were objective structured clinical examination-based. Other types of methods that were reported were workplace-based assessment; asynchronous, video-based assessment; knowledge-based assessment and performance-based, simulated, virtual assessment. Included studies used a diverse range of communications skills frameworks, rating scales and raters. Internal structure was the most reported source of validity evidence (130 studies (90%), followed by content-related (108 studies (74%), relationships with other variables (86 studies (59%), response processes (15 studies (10%) and consequences (16 studies (11%).

This scoping review identified gaps in the sources of validity evidence related to assessment method that have been used to support the use of CSA methods. These gaps could be addressed by studies explicitly defining the communication skill construct(s) assessed, clarifying the validity source(s) reported and defining the intended purpose and use of the scores (ie, for learning and feedback, for decision making purposes). Our review provides a map where targeted CSA development and support are needed. Limitations of the evidence come from score interpretation being constrained by the heterogeneity of the definition of communication skills across the health professions and the reporting quality of the studies.

About one-third of all patients with cancer in Germany are still of working age at the time of diagnosis. Therefore, occupational reintegration is an important goal after the completion of the treatment. Compared with the general population, patients with cancer are more frequently affected by unemployment, early retirement and reduced earning capacity pensions. Yet, there are no robust results about which factors determine occupational reintegration, whether downward social mobility is associated with a cancer diagnosis and which groups are particularly at risk for not returning to work or the loss of their social position. The aim of this study is to analyse social inequalities in occupational reintegration, work-related changes and vertical social mobility processes, as well as to explore the role of rehabilitative measures and other intermediary influences in these processes.

Data are collected in a retrospective cross-sectional study with a qualitative in-depth sequential mixed-methods design. For this purpose, patients from three federal states in Central Germany who have been diagnosed with cancer between 2017 and 2022 and are between 18 and 60 years will be asked to participate in this study. Participants answer a standardised questionnaire (written or online). A subsample will subsequently be questioned in a qualitative interview.

Analysis will be done by descriptive and multivariate methods as well as qualitative content analysis.

Ethics approval has been obtained from the Ethics Committee of the Medical Faculty at the Martin Luther University Halle-Wittenberg (reference number 2023-117). All research activities will be performed in accordance with the Declaration of Helsinki. Participants have to provide informed consent before enrolment. The study is registered at the German Clinical Trials Register. Results will be presented in peer-reviewed academic journals, at (international) conferences and on a joint workshop with stakeholders and patients.

The Belgian healthcare system is to a large extent hospital-centred, prompting government initiatives to shift care towards patient’s homes and reduce hospital stays. To avoid unnecessary hospital stays and offer alternative and innovative forms of care, the Belgian federal health authorities selected five pilot projects for transmural care for chronically ill children. Guided by the Medical Research Council framework, this study aims to evaluate the paediatric transmural care projects to inform new models for paediatric care.

Using a mixed-methods realist evaluation, the study comprises three phases: (1) initial programme theory development, (2) initial programme theory testing and (3) programme theory refinement. In a first phase, the initial programme theory rooted in the normalisation process theory will be refined from insights retrieved from document review and focus group interviews with healthcare professionals. In the second phase, the initial programme theory will be tested using empirical data. Routine data and questionnaires will examine whether characteristics of participants and outcomes are in line with the quintuple aim framework. Focus groups with children, parents and stakeholders, and document analysis will be used to evaluate the structure of the intervention, examine the process and context, and understand more in-depth the outcomes. A budget impact analysis will be used to assess whether the pilot project is affordable. In a third phase, qualitative and quantitative data will be analysed using a convergent mixed-methods model, involving continuous triangulation of multiple data sets to facilitate greater understanding of the context and refinement of the programme theory.

The study protocol was reviewed and approved by the Ethics Committee of the Ghent University Hospital (Belgian Registration Number B6702024000193) after consultation with all Ethics Committees of the participating hospitals. Written informed consent will be obtained from participants or their legal representatives prior to data collection. Participant confidentiality will be maintained throughout the study. Study results will be published in international peer-reviewed journals and will be presented at national and international conferences. The general population will be informed of the aggregated results.
