Title: CaTLET (Cancer Trials Leaflet Evaluation Tool) - An evaluation of information leaflets for patients entering cancer trials. This was a pilot study producing provisional findings: further development is planned.
Project Timescale: From 01 September, 2000 to 01 January, 1970
(Added to website on: 07 February, 2005 : Date last updated : 20 April, 2007)
Source of Funding:
Aims: To develop, in a partnership between the Faculty of Medicine, University of Leicester, and the NHS Centre for Health Information Quality (CHIQ), a tool (CaTLET) for evaluating information leaflets given to patients who are being asked to participate in cancer trials. To use CaTLET and a previously validated instrument (DISCERN) to appraise a sample of leaflets currently used in cancer trials.
Research Designs Used:
Study of views/experiences
Methods Used to Collect Data:
Research Project Description: CaTLET is a pilot project and it is anticipated that this will lead on to a generic version TriLET (Trial leaflet Evaluation Tool) which will be developed and validated in a more rigorous project. The setting for this research was the Faculty of Medicine at the University of Leicester, and hospitals in the Leicester area. An evaluation tool, modeled on the DISCERN instrument format, was drafted, initially based on quality criteria for patient information developed by CHIQ and a literature review of patients` preferences for information when entering clinical trials. This draft version was then sent out for consultation with a range of patients` voluntary organisations, patients` advocates, ethics committee representatives, oncologists, information specialists, and the Consumers` Advisory Group for Clinical Trials. The comments received during the consultation period were synthesised and used to modify the draft version. The final version in this pilot project was named CaTLET . The test-retest reliability and inter-rater reliability of the instrument was established by a multi-disciplinary team. CaTLET, together with the DISCERN instrument, was then used to appraise more than 50 patient information leaflets currently being used in cancer trials in a variety of centres in the UK. Results suggested large variability in the quality of information leaflets given to patients and indicated areas where significant improvements could be made. Many patient information leaflets fail to meet basic quality criteria and many do not address patients` needs as fully as they should.
Members of the public involved in the research project: Voluntary organisations, patients` advocates, the Consumers` Advisory Group for Clinical Trials, and an independent advocate for quality in research and healthcare on the multidisciplinary team.
Stages at which the public were involved:
Managing the research
Designing the research instruments
(eg questionnaires, patient information sheets)
Prioritising topic areas
Planning the research
Description of Public Involvement in Research Stages: Integral throughout by a managed, iterative process.
Training and support provided for either members of the public or researchers involved in the project:
Examples of ways the public have made a difference to the research project: Involvement of members of the public throughout, as representative users of patient information leaflets, has been crucial in the iterative process with health professionals, in order to determine what is required in those leaflets in order to improve the informed consent process, and the manner in which it should be presented.
Evaluating the impact of public involvement in the research:

Articles planned for the future:
Action Arising from the Research Project: A generic version of CaTLET, named TriLET (Trial Leaflet Evaluation Tool) is planned, and was given DoH encouragement in 2001. Development of this proto-version, to produce a reliable, validated generic tool has potential - in routine use - to guide both production and evaluation of leaflets. Such leaflets would be more likely to achieve better `informed consent`, signalling respectful research partnerships with participants. They could improve patients` understanding, achieve better concordance, and increase both clinician and patient satisfaction and commitment to the research process.
