Experiences with the inclusion of cancer patients with a migrant background and their relatives in the field of psycho-oncology]. / "Wir wussten, dass es schwierig wird, doch damit haben wir nicht gerechnet!" Erfahrungen beim Studieneinschluss von Krebspatient*innen mit Migrationshintergrund und Angehörigen im Bereich der Psychoonkologie.

ABSTRACT

BACKGROUND: The process of enrolling participants is an important component and often a time-consuming step in scientific research projects. Due to different financial, organisational and ethical framework conditions, the enrolment of participants is often a challenge. In this article, we report our experiences of enrolling patients in clinical trials made in the project "Psycho-oncological care of cancer patients with a migration background - a mixed methods study" (POM). METHODS: Participants were recruited through outpatient haemato-oncology practices. Patients and relatives were primarily made aware of the project by the treating physicians and recruited to participate in qualitative interviews. RESULTS: Nine patients and relatives were interviewed nationwide in individual qualitative interviews. In addition to the COVID-19 pandemic, there were other patient enrolment challenges. In many cases, participation was refused. The reasons included "not interested", the use of the terms "psycho-oncology" or "person with a migration background", family denying permission to participate, no face-to-face interview due to the COVID-19 pandemic as well as too much emotional distress and deterioration of health after prior consent. DISCUSSION: Enrolling study participants from vulnerable groups for a sensitive topic such as psycho-oncology entails multiple challenges. In order to achieve successful study inclusion, regular telephone and written exchanges with the respective practice staff proved to be helpful, allowing an overview of challenges to be gained and study inclusion to be evaluated and adjusted in a timely manner. CONCLUSION: In research projects with vulnerable groups and on sensitive topics, both a target-group-specific, sensitive approach in plain language (layman's terms) and regular consultations with the persons responsible for study inclusion in care facilities should take place in order to adapt the existing procedure during the study inclusion process, if necessary.
