Implementation and Quality (IMPAQT) – Claudia Hanson's research group

Our aim is to advance knowledge on how to develop, implement, and evaluate strategies to improve the quality of care globally. We focus largely, but not exclusively, on low-resource settings.

Our research

We primarily work on ‘implementation interventions’, thus interventions that support health workers, facilities or health systems to use available resources most effectively for the benefit of improved quality of care. We recognize the complexity of improving health care quality and health systems and that strong and long-term collaborations with universities and research institutions in the global South are essential. Our research is rooted in the contextual realities and the needs of people, health providers and local managers, guided by local and national priorities.

Experience in our groups spans from epidemiology, qualitative methods, implementation science, measurement and metrics and health systems and policy research.

Within our group, we are actively contributing to strengthening the interaction and synergies between education and research. We see education and training as part of our global commitment to thrive to a sustainable development. We are interdisciplinary and intercultural teachers who try to emphasize that teaching needs to go hand in hand with research at a university. Within our group we have members active in education management, course leadership and lecturing. We supervise doctoral and master students in global public health, students from other programs at Karolinska Institutet and at other Universities in and outside of Sweden.

Research projects

We work on methods for evaluating quality and evaluate ‘implementation interventions’ thus such interventions that support health workers, facilities or health systems to use available resources most effectively for good quality care.

In our team we have researchers experienced in epidemiology, quantitative and qualitative methods, implementation science, measurement and metrics, health systems, policy and health services research and clinical care.

Our work is rooted in the contextual realities and the needs of people, health providers and local managers, guided by local, national and global priorities. Our research aims to evaluate quality and investigates ‘implementation interventions’ that support health workers, facilities or health systems to use available resources most effectively for good quality care.

Labour companionship is the continuous presence of a woman’s person of choice through labour and birth. It is a non-clinical intervention recommended by the World Health Organization to improve the quality of maternal care.

Our research team currently supports three PhD students contributing to labour companionship within the ALERT and QUALI-DEC interventions.

Bianca Kandeya’s PhD is nested in the ALERT study and it focuses on perceptions and experiences of women, companions and maternity care providers regarding the opportunities and challenges of companionship in labour. The PhD also aims to understand women's experiences of childbirth with/without companions before and after the ALERT intervention considering existing evidence that having a companion of choice throughout labour and child birth improves women’s’ experience of child birth.

Mercedes Vila Ortiz PhD project focuses on the implementation of labour companionship in Argentina within the QUALIDEC project. Its aim is to describe and explain how companionship is implemented as part of the QUALI-DEC intervention, what changes this stimulated and how the intervention met the needs of health providers, women and companions in eight hospitals of Buenos Aires City, addressing key actors’ perceptions and experiences.  

Soha El Halabi who through her PhD journey aims to inform the implementation of companionship models through understanding the context and processes and determining the effects and costs of available interventions. Her PhD project includes the eight participating countries in ALERT and QUALI-DEC: Argentina, Benin, Burkina Faso, Malawi, Tanzania, Thailand, Uganda and Vietnam.

Vaccine confidence

There are several projects that currently take place in the field of vaccine confidence building within the IMPAQT research group.

Understanding vaccine hesitancy and rumours

This project is funded by FORTE, it studies rumours and trust in vaccine hesitant communities in Sweden. These communities include migrant communities, anthroposophic communities and Swedish speaking online communities. We use qualitative and social media listening methods to study the origin of rumours and explore the concept of trust using participatory action methods.

Africa Vaccine Trust Network

This is an ongoing VR funded project (2023-2024) that connects four African countries (Benin, Ethiopia, Nigeria and Uganda) to develop joint research questions regarding emerging vaccine confidence questions, particularly among health workers.

Vaccine confidence among health workers in Nigeria and Ethiopia

This is a VR funded project (2023-2026) that aims to test an innovative social media intervention that addresses specific vaccine concerns (particularly regarding new vaccines) among health workers.

HPV vaccine confidence in Addis Ababa, Ethiopia

This is a project that has received funding from the Einhorn Foundation. The aim is to understand HPV vaccine hesitancy among adolescents, parents and the community in selected schools in Addis Ababa, Ethiopia that have shown low HPV vaccine uptake.

Global HPV burden study

This is a large-scale project funded by Bill and Melinda Gates that spans across seven countries that have not yet implemented national HPV vaccine programmes. The aim of the project is to establish HPV16 and 18 prevalence and explore intention and barriers to vaccination once vaccines are available.

Vaccine confidence and faith-leaders

This project explored the role that faith-leaders play in building vaccine confidence in Addis Ababa, Ethiopia.

COVID-19 vaccine confidence in Sweden

This project investigated COVID-19 vaccine concerns among migrants and among online communities in Sweden.

Essential Emergency and Critical Care (EECC)

Critical illness results in millions of deaths each year. Care for those with critical illness is often neglected due to a lack of prioritisation, co-ordination, and coverage of timely identification and basic life-saving treatments. To improve care, we are working on the innovative concept, Essential Emergency and Critical Care (EECC) – the care that all critically ill patients should receive in all hospitals in the world.

Essential emergency and critical care should be part of universal health coverage, is appropriate for all countries in the world, and is intended for patients irrespective of age, gender, underlying diagnosis, medical specialty, or location in the hospital. Essential emergency and critical care is pragmatic and low-cost and has the potential to improve care and substantially reduce preventable mortality. 

Critical Illness and Sepsis Prevalence and Outcomes Studies (CRISPOS)

We are conducting prospective cohort studies of the prevalence and outcomes of patients with critical illness and sepsis in hospitals in Malawi, Sri Lanka and Sweden. The aims are to determine the proportion of in-patients that are critically ill and that have sepsis and to determine the mortality rates and the relative risk of critical illness and sepsis.

Improving the care of critically ill patients in Malawi and Tanzania

We are conducting several projects in hospitals in Malawi and Tanzania to improve the care and outcomes of patients with critical illness. Projects include the Vital Signs Directed Therapy project, the ICU Register and Outcomes project, paediatric critical care projects and peri-operative mapping projects.
