Concept↦Safety↦Safety in Studies↦Participant Risk-Benefit
Was betrifft es? Warum ist das wichtig?
Based on the planned target population, it is crucial that its composition is taken into consideration when assessing the risk-benefit ratio of the study (e.g. health / disease status, vulnerable population such as children, pregnant women).
Study risks and burdens include:
- Unwanted (serious) side effects related to the intervention or its procedures
- The new treatment is not as effective as intended, or is not better than a standard treatment, and/or has more side effects
- Impairment in the quality of life
Benefits include:
- Efficacy of study treatment
- Access to novel treatment options
- Close monitoring with more frequent health check-ups
- Psychosocial benefits (e.g. play a more active role in personal health care)
- Ability to contribute to medical research that may save future lives, or improve the health of future patients

For interventional studies, the Swiss law provides clear risk-benefit guidelines for the use of placebo groups.
In studies with an expected direct benefit, the use of a placebo or non-treatment is only allowed if:
- No additional risk of serious or irreversible harm is to be expected, and
- No standard treatment is available; or
- The use of a placebo is required for compelling, scientifically sound methodological reasons, in order to establish the efficacy or safety of a treatment method
Was muss ich befolgen?
As a SP-INV define potential risks and benefits for participants during study conduct.
Assess:
- Type of risks (e.g. are they serious or non-serious)
- Risk detection methods (e.g. specific symptoms, lab reports)
- Likelihood of risk occurrence (e.g. expected frequency)
- Severity of risks (e.g. mild, moderate, severe)
- Risk duration (e.g. a rash that lasts one week is more acceptable than if it lasts for one month or longer)
- Reversibility of risks
Include potential psychosocial risks and/or quality of life impairments.
For benefit assess:
- Type of expected benefit (e.g. pain reduction, a decrease in occurrence and duration, better quality of life)
- Psychosocial benefits or the importance of the study for future patients.
Document expected study risks in the:
- Participant information sheet
- Study protocol (e.g. include risk mitigating measures)
For more information refer to Quality & Risk in this study guide.

It is the responsibility of the SP-INV and Site-INV to ensure participants understand risks involved in study participation.
A shift in the study risk-benefit ratio (e.g. new risks) potentially affecting study participants requires that:
- The SP-INV implements respective PIS updates
- The Site-INV informs participants about new risks, and if applicable, asks the participant to re-consent to study participation
