| Cluster randomised controlled trial of computer decision support for management of familial cancer in primary care |
| Source of record | UK Trials |
| ISRCTN | ISRCTN71084565 |
| Date ISRCTN assigned | 16/10/2002 |
| Local reference number(s) | N/A |
| Public title | Cluster randomised controlled trial of computer decision support for management of familial cancer in primary care |
| Scientific title | |
| Acronym | GRAIDS Trial |
| Disease/condition/study domain | Familial breast or colorectal cancer |
| Study hypothesis | This project applies the Medical Research Council (MRC) framework for evaluation of complex interventions and encompasses an optimisation trial of computer decision support for familial cancer in primary care and an audit of current referral patterns for familial cancers to inform power calculations for a subsequent multi-centre trial. This optimisation trial will pilot procedures for the delivery and assessment of the intervention and will, in addition, seek to optimise and identify the most cost-effective intervention that should be evaluated in a full-scale trial by having a fixed and an adaptive intervention arm. The underlying hypotheses are that the provision of computer decision support and a family history questionnaire in primary care will lead to more appropriate and cost-effective referrals for familial cancers (i.e. that are in line with regional referral criteria), and will enable patients to make better informed decisions about their familial risk of cancer. |
| Design/methodology | Randomised controlled trial |
| Research ethics review | Ethics information not required at time of registration. |
| Countries of trial | United Kingdom |
| Participants - inclusion criteria | Patients approaching their General Prectitioner (GP) or practice nurse with concerns about their family history of cancer. |
| Participants - exclusion criteria | 1. Children under 18 2. People with learning difficulties 3. Severely ill 4. Other vulnerable groups e.g. mental illness, dementia |
| Patient information material | |
| Anticipated start date | 01/04/2002 |
| Anticipated end date | 30/09/2005 |
| Status of trial | Completed |
| Target number of participants | 1300 |
| Interventions | Intervention arm subjects: Patients approaching their GP or practice nurse with concerns about their family history of cancer will be given a family history questionnaire to take home to complete, and then return for a second appointment. At the second consultation the trained lead clinician will enter information supplied by the patient and the family history questionnaire into the GRAIDS software. The software will support discussions with the patient about their risk of cancer and subsequent management. Control arm subjects: Subjects in the control practices approaching their GP or practice nurse with concerns about familial cancer will have a normal consultation according to their GPs current practice. All subjects: Subjects who are referred to the Regional Genetics Clinic will be asked to complete the measure of Informed Decision Making (IDM) questionnaire. This request will come from the Clinic with their appointment letter. The subjects will be requested to return the completed questionnaire to the Study Team. Subjects in the intervention practices who are not referred to the Regional Genetics Clinic will be sent a measure of IDM questionnaire by the Study Team. Six months after they have returned the measure of IDM, the subjects will be sent a second measure of IDM to complete and return to the Study Team. Trial Principal Investigator: Professor Jon Emery |
