Development↦Documents↦Required Documents↦Participant Information
What is it? Why is it important?
Recruiting study participants necessitates that they be adequately informed and formally consent to study participation.
A participant informed consent process should be in place, which includes the following documents:
- The Participant Information Sheet (PIS): provides candidates considering study participation with the necessary information needed to understand the study, and enable them to make a sound decision whether to participate in the study
- The Informed Consent Form (ICF): is handed out together with the PIS. It is the official document where participants confirm their agreement to participate in a study in writing, by dating and signing the document
Within the context of Patient and Public Involvement (PPI), patients can be valuable contributors by reviewing PIC/ICF documents. This improves clarity, readability, and participant understanding of the study, leading to better participant experience when deciding on study participation.
What do I need to do?
As a SP-INV:
- Select and download the official PIS/ICF templates applicable to your study from the swissethics webpage (e.g. children, individuals without capacity, emergency patients). The template provides a standardized document structure and comprehensive guidance on the required content
- As applicable, request PPIE support to obtain feedback on PIS/ICF or other recruitment material. Ask PPIE collaborators to highlight unclear wording or complex sections, assess readability, length, and overall clarity
In addition:
- Establish an informed consent process according to your target population. Describe the informed consent process in your study protocol
- Define processes to ensure only Ethics Committee (EC) approved PIS/ICF remain in circulation during study conduct. For Medical Device studies with risk-category C the PIS must also be submitted to Swissmedic
- In the event of a multicentre study, adapt documents according to site specific layouts, and add site-specific contact details (i.e. local ECs approve PIS/ICF-site documents under their jurisdiction)
- Ensure PIS and ICF are reviewed and approved by the EC before implementation. As with the study protocol, EC approval is based on a particular PIS/ICF version (e.g. document identification).
More
Based on:
- Target group, additional legal requirements may apply to the informed consent process (e.g. children studies, where the legal guardian also approves study participation)
- Participant language background, literacy skills, or cognitive reasons, the EC might approve an exemption to the written PIS/ICF form
- Changes or amendments, require that identifiers are adapted accordingly (e.g. version numbers, release dates), and that the documents are re-approved by EC.
