[Selft-test kits on the high street, really useful ?]

Area of Science:

• Health Sciences
• Medical Diagnostics
• Public Health

Background:

• The proliferation of over-the-counter self-test kits presents challenges for healthcare providers.
• The clinical utility and health system impact of most self-tests remain largely unevaluated.
• Existing evidence for self-test efficacy is limited, with notable exceptions like HIV and Fecal Immunochemical Tests (FIT).

Purpose of the Study:

• To provide healthcare professionals with a structured approach to assessing the value of available self-test kits.
• To offer recommendations for guiding patients in the appropriate use of self-tests.
• To clarify the potential benefits and drawbacks of self-testing for both consumers and the healthcare system.

Main Methods:

• Literature review and synthesis of current evidence on self-test kit effectiveness.
• Development of a critical appraisal tool (reading grid) for evaluating self-tests.
• Analysis of the Swiss healthcare system context regarding self-test implementation.

Main Results:

• Most self-test kits lack robust evidence of efficacy and benefit to the healthcare system.
• Specific self-tests, such as those for HIV and FIT, demonstrate established utility.
• A framework for evaluating self-tests is proposed to aid clinical decision-making.

Conclusions:

• Healthcare providers need guidance to navigate the expanding market of self-test kits.
• Careful evaluation is necessary to ensure self-tests are beneficial for patients and the healthcare system.
• Further research is needed to establish the effectiveness of many currently available self-tests.
