A guide for a student-led doctoral-level qualitative methods short course in epidemiology: faculty and student perspectives

Qualitative research and mixed methods are core competencies for epidemiologists. In response to the shortage of guidance on graduate course development, we wrote a course development guide aimed at faculty and students designing similar courses in epidemiology curricula. The guide combines established educational theory with faculty and student experiences from a recent introductory course for epidemiology and biostatistics doctoral students at the University of Zurich and Swiss Federal Institute of Technology, Zurich. We propose a student-centred course with inverse classroom teaching and practice exercises with faculty input. Integration of student input during the course development process helps align the course syllabus with student needs. The proposed course comprises six sessions that cover learning outcomes in comprehension, knowledge, application, analysis, synthesis and evaluation. Following an introductory session, the students engage in face-to-face interviews, focus group interviews, observational methods, analysis and how qualitative and quantitative methods are integrated in mixed methods. Furthermore, the course covers interviewer safety, research ethics, quality in qualitative research and a practice session focused on the use of interview hardware, including video and audio recorders. The student-led teaching characteristic of the course allows for an immersive and reflective teaching-learning environment. After implementation of the course and learning from faculty and student perspectives, we propose these additional foci: a student project to apply learned knowledge to a case study; integration in mixed-methods; and providing faculty a larger space to cover theory and field anecdotes.

What is public trust in national electronic health record systems? A scoping review of qualitative research studies from 1995 to 2021

Objective

Public trust in national electronic health record systems is essential for the successful implementation within a healthcare system. Research investigating public trust in electronic health records is limited, leading to a lack of conceptual clarity. In response, the objective of this study is to gain a clearer understanding on the conceptualizations of public trust in electronic health records, which can support the implementation of national electronic health record systems.

Methods

Guided by the PRISMA-ScR checklist, a scoping review of 27 qualitative studies on public trust in electronic health records found between January 2022 and June 2022 was conducted using an inclusive search method. In an iterative process, conceptual themes were derived describing the promoters and outcomes of public trust in electronic health records.

Results

Five major conceptual themes with 15 sub-themes were present across the literature. Comprehension, autonomy, and data protection promote public trust in electronic health record; while personal and system benefits are the outcomes once public trust in electronic health records exists. Additional findings highlight the pivotal role of healthcare actors for the public trust building process.

Conclusions

The results underscore comprehension, autonomy, and data protection as important themes that help ascertain and solidify public trust in electronic health records. As well, health system actors have the capacity to promote or hinder national electronic health record implementation, depending on their actions and how the public perceives those actions. The findings can assist researchers, policymakers, and other health system actors in attaining a better understanding of the intricacies of public trust in electronic health records.

What does it take to create a European Health Data Space? International commitments and national realities

Public health concerns in Europe demonstrate the necessity of building a health policy that could contribute to the long-term sustainable development of the European Union (EU), as stated in the European Health Union (EHU) manifesto. The main desire to create an EHU is embodied in the launch of the European Health Data Space (EHDS). The EHDS seeks to foster a genuine single market for digital health services and products by, among other things, accelerating the uptake and implementation of harmonised and interoperable electronic health record (EHR) systems across the EU. In the context of primary and secondary use of EHR data, developments in Europe have thus far resulted in patchy and, in some places, non-interoperable solutions. Taking the gap between international ambitions and national realities as a starting point, this paper contends that both EU level and Member State level circumstances should be considered to make the EHDS a reality.

Promoting participation in remote digital health studies: An expert interview study

Background

Remote digital health studies are on the rise and promise to reduce the operational inefficiencies of in-person research. However, they encounter specific challenges in maintaining participation (enrollment and retention) due to their exclusive reliance on technology across all study phases.

Objective

The goal of this study was to collect experts' opinions on how to facilitate participation in remote digital health studies.

Method

We conducted 13 semi-structured interviews with principal investigators, researchers, and software developers who had recent experiences with remote digital health studies. Informed by the Unified Theory of Acceptance and Use of Technology (UTAUT) framework, we performed a thematic analysis and mapped various approaches to successful study participation.

Results

Our analyses revealed four themes: (1) study planning to increase participation, where experts suggest that remote digital health studies should be planned based on adequate knowledge of what motivates, engages, and disengages a target population; (2) participant enrollment, highlighting that enrollment strategies should be selected carefully, attached to adequate support, and focused on inclusivity; (3) participant retention, with strategies that minimize the effort and complexity of study tasks and ensure that technology is adapted and responsive to participant needs, and (4) requirements for study planning focused on the development of relevant guidelines to foster participation in future studies.

Conclusions

Our findings highlight the significant requirements for seamless technology and researcher involvement in enabling high remote digital health study participation. Future studies can benefit from collected experiences and the development of guidelines to inform planning that balances participant and scientific requirements.

Beyond high hopes: A scoping review of the 2019-2021 scientific discourse on machine learning in medical imaging

Machine learning has become a key driver of the digital health revolution. That comes with a fair share of high hopes and hype. We conducted a scoping review on machine learning in medical imaging, providing a comprehensive outlook of the field's potential, limitations, and future directions. Most reported strengths and promises included: improved (a) analytic power, (b) efficiency (c) decision making, and (d) equity. Most reported challenges included: (a) structural barriers and imaging heterogeneity, (b) scarcity of well-annotated, representative and interconnected imaging datasets (c) validity and performance limitations, including bias and equity issues, and (d) the still missing clinical integration. The boundaries between strengths and challenges, with cross-cutting ethical and regulatory implications, remain blurred. The literature emphasizes explainability and trustworthiness, with a largely missing discussion about the specific technical and regulatory challenges surrounding these concepts. Future trends are expected to shift towards multi-source models, combining imaging with an array of other data, in a more open access, and explainable manner.

About the Essence of Trust: Tell the Truth and Let Me Choose—I Might Trust You

Trust is critical to the success of health care. We witness a diversification of trust constructs which is due to the context specificity of trust and the popularity of trust in marketing, public, and political debate. This diverse use of trust leads to confusion. To contribute to the dissolution of this confusion, I propose that the essence of trust follows Tell the truth and let me choose—I might trust you. Inferring from empirical and theoretical work, I argue that the conceptual framework of trust is comprised of: communication, truthful information, autonomy, alternatives, and no guarantee. This oversimplification aims to stimulate a debate about the common denominator of existing conceptual frameworks of trust in health care. By refining and agreeing on the core of trust in health care, we will be able to improve debate, improve comparability among trust studies, and improve understandability of policy recommendations to foster trust in health care.

Can we know if donor trust expires? About trust relationships and time in the context of open consent for future data use

As donor trust legitimises research, trust is vital for research in the fields of biomedicine, genetics, translational medicine and personalised medicine. For parts of the donor community, the consent signature is a sign of trust in research. Many consent processes in biomedical research ask donors to provide their data for an unspecified future use, which introduces uncertainty of the unknown. This uncertainty can jeopardise donor trust or demand blind trust. But which donor wants to trust blindly? To reduce this uncertainty, we explore first, which future-proof actors donors could trust when signing a consent form. Second, we discuss the question Can we know if donor trust expires? and what prevents donor trust from expiring. Finally, we present possible measures that can help to nurture trust in the far future. In this article, we draw on our previous research on trust in biomedical research, on trust in the broader healthcare system and Niklas Luhmann's and Anthony Giddens' trust theories. Our findings suggest that, in the far future, researchers will need to consider donor autonomy, as well as societal norms and values of the time period in which the data were donated. They will need to find mechanisms where possible to publicly announce the use of old data sets. However, foremost researchers will need to treat the data respectfully. It remains vital that professionals and the society continue to elaborate on the norms and values that shape the common understanding of what is morally right and wrong when researching data.

Public Trust and Trustworthiness in Biobanking: The Need for More Reflexivity

Low levels of public trust in biobanks are perceived to be a deterrent to participation and a threat to their sustainability. Acting in a "trustworthy" manner is seen to be one approach to ensuring public trust in biobanks. Striving to improve public trust in biobanks and prioritizing the need for institutional trustworthiness are both vital endeavors. However, there has been little discussion in the context of biobanking about the meaning of these two concepts, and the relationship between them. In this article, we argue that it is important to examine this, to ensure clarity around their meaning, as well as their relationship with each other as they apply to biobanking. We conclude by making a series of recommendations for biobanks.

Evidence-based guiding principles to build public trust in personal data use in health systems

Objective

Public trust in health systems is pivotal for their effective and efficient functioning. In particular, public trust is essential for personal data use, as demonstrated in debates in many countries, for example, about whether data from COVID-19 contact tracing apps should be pooled or remain on individuals’ smartphones. Low levels of public trust pose a risk not only to health system legitimacy but can also harm population health.

Methods

Synthesising our previous qualitative and theoretical research in the English National Health Service which enabled us to conceptualise the nature of public trust in health systems, we present guiding principles designed to rebuild public trust, if lost, and to maintain high levels of public trust in personal data use within the health system, if not.

Results

To build public trust, health system actors need to not rush trust building; engage with the public; keep the public safe; offer autonomy to the public; plan for diverse trust relationships; recognise that trust is shaped by both emotion and rational thought; represent the public interest; and work towards realising a net benefit for the health system and the public.

Conclusions

Beyond policymakers and government officials, the guiding principles address a wide range of actors within health systems so that they can work collectively to build public trust. The guiding principles can be used to inform policymaking in health and health care and to analyse the performance of different governments to see if those governments that operate in greater conformity with the guiding principles perform better.

Limits of data anonymity: lack of public awareness risks trust in health system activities

Public trust is paramount for the well functioning of data driven healthcare activities such as digital health interventions, contact tracing or the build-up of electronic health records. As the use of personal data is the common denominator for these healthcare activities, healthcare actors have an interest to ensure privacy and anonymity of the personal data they depend on. Maintaining privacy and anonymity of personal data contribute to the trustworthiness of these healthcare activities and are associated with the public willingness to trust these activities with their personal data. An analysis of online news readership comments about the failed care.data programme in England revealed that parts of the public have a false understanding of anonymity in the context of privacy protection of personal data as used for healthcare management and medical research. Some of those commenting demanded complete anonymity of their data to be willing to trust the process of data collection and analysis. As this demand is impossible to fulfil and trust is built on a false understanding of anonymity, the inability to meet this demand risks undermining public trust. Since public concerns about anonymity and privacy of personal data appear to be increasing, a large-scale information campaign about the limits and possibilities of anonymity with respect to the various uses of personal health data is urgently needed to help the public to make better informed choices about providing personal data.

Transparency About Governance Contributes to Biobanks' Trustworthiness: Call for Action

This article examines biobank transparency mechanisms vis-à-vis their public information, as found on the public biobank webpages. Two independent studies about biobank governance in Europe and Canada identified a lack of governance-related information provided by biobanks on their public webpages. This lack of transparency stands in contrast to governance best practice guidelines highlighting the importance of transparency as a principle of good governance. Transparency is especially important as many biobanks are publicly funded, and it contributes to accountability and supports the development of donor trust in biobanks. Empirical evidence shows that the public supports greater transparency about biobank governance. It will be important that information provided online is relevant and accessible for a variety of different stakeholders (e.g. public and private sector scientists and institutions, donors and potential donors, members of the public). Transparency standards, however, need to be proportionate to avoid the situation that only large-scale biobanks can allocate appropriate resources to fulfil them. Implementing adequate standards of transparency about biobanks' governance will increase accountability but also allow current and future participants to make more informed decisions about their participation in biobank activities.

A Case for Transformative Learning in Medical Ethics Education

In this article, we discuss the current state of medical ethics education. In Higher Education, ethics is taught predominantly through discussion and case study-based teaching formats. At present, however, only little can be said about the adequacy of these teaching methods in attaining complex educational objectives as ethics education poses challenges regarding meaningful student assessment and evaluation of educational methods. Output-oriented evaluation and assessment paradigms that centre quantified student performance fail to meaningfully capture the learning of ethics. Currently, we argue that comparatively small efforts are being devoted to the advancement of innovative and adequate approaches to teaching and assessment in ethics education. In response to these shortcomings, drawing from educational traditions that focus on preparatory activities, we work towards a new approach to evaluate teaching methods and assessing the learning in ethics.

Vaccination, Autonomy, Complexity, Solidarity - Ethical analyses of a German policy discourse

Background

Currently, measles immunization is high on the agenda of academic and public discourses - on both sides of the Atlantic. In Germany, the discussion of mandatory (measles) immunization was intensively publicly discussed in Spring 2019. Many stakeholders, including federal politicians, plea for mandatory measles immunization. In our paper we analyse the discourse from an ethical point of view.

Methods

Statements and arguments from German stakeholders in the public debate in 2019 are analysed (among them statements of the federal minister of health, the German Medical Association, NGOs and the National Ethics Council). A vaccination ethics framework and a public trust framework are applied in the analysis.

Results

Politicians and other public stakeholders debate (measles) immunization and increasingly demand mandatory (measles) vaccination. However, frequently it is unclear which vaccinations or immunization programmes they refer to. They often do ignore the epidemiological situation of immunization rates in Germany, regional differences, relevant target groups and implementation mechanisms, including potential sanctions. This way they simplify the complex problem and offer (populist) simplistic solutions. Normative arguments of stakeholders repeatedly use conceptions of ’autonomy’ and ’harm’; but sometimes also ’solidarity’ is mentioned.

Conclusions

The call for mandatory measles immunization of school and kindergarten children is offering no adequate and sufficient solution to the problem of elimination of measles. Nevertheless, it contributes to reducing infection risks for the children in care and schooling facilities. Rather, the problem has to be understood in its complexity before discussing the ethical challenges and making effective policy recommendations. When discussing ways to increase immunization rates, ethical values like public trust and solidarity have to be in the foreground - not (only) the debate of autonomy and its restriction.

Key messages

In German policy discourses 2019, the discussion of “mandatory (measles) vaccination” often shows inaccuracies regarding definitions and facts. These have to be clarified before ethical analysis. Ethical issues regarding the voluntariness of measles vaccination relate also to the ethical concepts of solidarity and public trust and not only to autonomy.

Development of the mHealth App Trustworthiness checklist

BACKGROUND

Mobile health applications (mHealth apps) currently lack a consensus on substantial quality and safety standards. As such, the number of individuals engaging with untrustworthy mHealth apps continues to grow at a steady pace.

OBJECTIVE

The purpose of this study was to investigate end-users' opinions on the features or actions necessary for trustworthy mHealth apps; and to convey this information to app developers via a succinct but informative checklist: the mHealth app trustworthiness checklist.

METHODS

The checklist was formulated in three stages: (a) a literature review of studies identified the desirable features of the most prolific mHealth apps (health and fitness apps); (b) four focus group sessions with past or current users of these apps (n = 20); and (c) expert feedback on whether the checklist items are conceivable in a real-life setting (n = 6).

RESULTS

Five major themes emerged from the focus group discussions: informational content, organizational attributes, societal influence, technology-related features, and user control factors. The mHealth app trustworthiness checklist was developed to incorporate these five themes and subsequently modified following expert consultation. In addition to the trustworthiness themes, we identified features that lie between trust and mistrust (limited digital literacy and indifference) as well as 10 features and actions that cause end-users to mistrust mHealth apps.

CONCLUSION

This study contributes to the evidence base on the attributes of trustworthy mHealth apps. The mHealth app trustworthiness checklist is a useful tool in advancing continued efforts to ensure that health technologies are trustworthy.

Why public trust in health care systems matters and deserves greater research attention

Considering the underlying importance of trust, there is too little research into the understanding, protection and recovery of trust in health care systems, not only for the effective functioning of health care systems but also for society in general. Several researchers have pointed towards a contemporary crisis of trust in health care systems and there have been many examples that show the severe effects of mistrust. More research into public trust in health care systems could contribute to improving efficiency while protecting the health of the public.

Das Speichelgangkarzinom der Glandula Sublingualis

RATIONALE

Pleomorphic adenoma is the most common neoplasm of major and minor salivary gland origin, followed by infectious reasons and sialolithiasis. Less common are adenocarcinomas presented. The salivary duct carcinoma represents a rare variant of the group of adenocarcinomas originated from the salivary glands, especially extremely rare from minor salivary gland origin.

CASE REPORT

We report about a 52 year old male patient presenting with painless, non-ulcerating tumor at the floor of the mouth. Since 2 weeks ingestion was painful. Further ENT-investigations including endoscopy and scans (MRT, ultrasound) showed no pathology. In particular, growth of cervical lymph nodes and distant metastases were not revealed. A biopsy showed a rare salivary duct carcinoma of comedo-type originated from the left sublingual salivary gland. The patient underwent an operation: the tumor was extirpated in toto, and, as the pathohistological investigation confirmed, in sano. Additionally a neck dissection at the left side was performed, followed by the radiation of the tumor region and the lymphatic neck regions, after sufficient reconvalescence. The tumor-classification was pT3, pN0. Since 3 years no recurrence of the tumor was confirmed.

DISCUSSION

Salivary duct carcinoma is a rare, high-grade malignant epithelial neoplasm, which occurs almost exclusively in the parotid. As presented, it can also occur in minor salivary glands. Histologically it is composed of structures that resemble expanded salivary glands. Comedonecrosis of these structures is a frequent feature. There is some histologic similarity to intraductal carcinoma of the breast. Differential diagnosis comprises adenoid cystic carcinoma, metastases of other adenocarcinomas, such as the carcinoma of the thyroid gland and the comedocarcinoma of the breast. Because of its poor prognosis a rapid and radical therapy is recommended.

CONCLUSION

A rare case of a salivary duct carcinoma of sublingual salivary gland origin is presented. Usually the prognosis is poor. The adequate therapy is the complete surgical extirpation including the surgery of the regional lymphatic nodes and the additional radiotherapy.

Early antibody-forming cells of double specificity

Simultaneous immunization of mice with sheep and pigeon erythrocytes results in multiplication not only of spleen cells capable of specifically agglutinating on their surface one or other of these antigens, but of spleen cells agglutinating both kinds of erythrocytes. These latter cells only appear on the 3rd day following immunization and tend to disappear after the 10th day. Their peak number is reached on the 5th day, when more than 10 per cent of the specific cells show double specificity.

When sheep erythrocytes are given 1 or 3 days before pigeon erythrocytes, the cells showing double specificity appear and disappear earlier after injection of the second antigen. These kinetics and those of the corresponding haemagglutinins suggest that such cells simultaneously synthesize antibodies of two different specificities.

Selective immune reactivity to DNP-poly-L-lysine in randomly bred guinea-pigs

The specific immune response towards the synthetic antigen DNP—p(Lys) in randomly bred guinea-pigs has been investigated. A full immunological response, namely delayed hypersensitivity, PCA reactive, complement fixing and mercaptoethanol sensitive antibodies was obtained in nearly half the animals. The other half also showed an immune response restricted, however, to complement fixing and mercaptoethanol sensitive antibodies. Genetic heterogeneity of these animals with respect to immunization to DNP—p(Lys) was thus found to be reflected in the type of immune response induced rather than in an all or none reactivity.
