Towards EQUIty in MEDtech - Reducing Gender and Sex Bias in Active Implantable Medical Devices [EQUIMED]

Research Project  | 2 Project Members

EQUIMED investigates sex and gender inequalities in implantable medical devices. Through interviews and multidisciplinary research, it aims to improve equity in medical technology.

Despite technological advancements, medical devices do not function the same way for men and women, with women experiencing more adverse effects. Implantable devices are particularly affected by sex and gender biases. EQUIMED studies this issue in Switzerland, the UK, and Germany by analyzing data, interviewing experts and patients, and evaluating ethical policies. Its goal is to make these devices safer and more effective for everyone.

EQUIMED seeks to understand and reduce these inequalities by exploring why women and gender minorities face higher risks and what factors contribute to these disparities. Its research will support the development of fairer solutions for implantable medical devices, such as pacemakers and neural implants, while also setting new ethical standards in medical technology.

By addressing biases in research, design, and regulation, EQUIMED aims to improve the safety of medical devices for all. The project will provide evidence-based recommendations to help policymakers, manufacturers, and healthcare professionals create more inclusive technologies. Collaboration between regulators, industry, and healthcare providers is essential to ensuring safer and fairer medical devices for everyone.

Engaging older persons in the community to promote frailty prevention and reduce social isolation

Research Project  | 3 Project Members

Background and rationale for project

Frailty is a major public health challenge. Frailty is a multidimensional syndrome in which a person accumulates impairments in multiple life domains due to ageing. Examples include physical impairments (e.g. reduced mobility), social status (e.g. social isolation) and cognition impairment. Frailty predisposes a person to negative health outcomes and is associated with long-term disability, a lower quality of life, and high costs. As impairments accumulate, persons are less able to participate in society, interact with their direct environment, and become socially isolated. Social isolation contributes to social frailty and physical frailty. Both frailty and social isolation can therefore be considered key outcomes for novel public health solutions.

Overall objective and specific aims

The overall objective is to develop a program theory for engaging older persons in a program that combines physical and social activities to prevent frailty and reduces social isolation, operationalize this program for adoption and implementation in the community setting, and evaluate the effectiveness and implementation in two Swiss Cantons. The ENGAGE project will achieve this through the following aims:

  1. To investigate current practice regarding screening and management of older persons’ frailty risk and social isolation in primary and community care, and identify determinants for improving these outcomes in this setting.
  2. To investigate experiences and perceptions of older persons concerning their participation in a community program that focusses on physical activity and social engagement, and identify determinants for their participation.
  3. To develop a program theory for frailty prevention and reduction of social isolation and to operationalise this in a program that combines physical and social activities that is adopted and implemented in the community setting.
  4. To implement the program in two Swiss cantons and test the acceptability and feasibility, and to evaluate its impact on reducing frailty and social isolation in older persons living in the community, and to identify determinants for and costs of implementation.

Methods

A multi-phased mixed methods project methodology will be used, in collaboration with a Patient and Public Involvement (PPI) group. First, a mixed methods study will be performed using QUAN – QUAL explanatory sequential design, including a survey and interviews with healthcare professionals and community stakeholders (Objective 1). Second, a qualitative study using semi-structured interviews with older persons will be conducted, followed by group discussions using a World Café methodology (objective 2). Third, Intervention Mapping will be used to develop a program theory for preventing frailty and reducing social isolation, and will be operationalized in a program in the community that combines physical and social activities (objective 4). Fourth, a pragmatic effectiveness–implementation hybrid type-1 trial will be conducted to evaluate the impact of the program, including its effects on frailty and social isolation. A pilot study will be embedded to evaluate study burden, acceptability and feasibility. A process -and economic evaluation are included to investigate the implementation and inform scale-up strategies and costs.

Expected results

The first program theory for frailty prevention in the community will be developed. This will be the first experimental study combining physical and social activities for frailty prevention and reduction of social isolation. This will be the first project studying implementation of frailty prevention in the community, informing scale-up.

Diagnosis – AI or Doctor? (DiAD) Investigating the Ethical and Practical Implications of Patient use of Chatbot AIs Compared with Human Doctors in Internal Medicine

Research Project  | 3 Project Members

Released in November 2022, ChatGPT gained over 100 million users in just two months to become the fastest growing application of all time. This Natural Language Processing Artificial Intelligence is capable of producing human-like responses on an incredibly large range of topics. It is inevitable that ordinary people will use it for medical diagnostic purposes, much as they do any other search engine. Although it, and other NLP tools like it, are comparable in diagnostic accuracy to human doctors, their use as substitutes to, or surrogates for, human doctors raises numerous ethical challenges. Not least of which is the impact this will have on vital doctor-patient relationships in under-served communities.


Current research focuses on quantitative research which does not take into consideration real-world patient experiences. The proposed project will provide an in-depth analysis of real-world patient experiences of using NLP tools in comparison to human doctors.


Following a scoping review, the project will use a novel qualitative research methodology. Real-world patients will be interviewed before a doctor’s consultation. They will then immediately engage in a similar mock consultation with an NLP tool. Data will be subjected to thematic analysis and recommendations produced for NLP tool developers and Swiss policy makers.
