| Scientific title | The POSEIDON trial: Promoting cOllaborative Support and Education in Diabetes for minOrity ethNic groups |
| Study acronym | POSEIDON |
| Study objectives | Informal story-sharing groups led by bilingual health advocates in the patient's own language will be no less effective than standard nurse led diabetes education through an interpreter, on clinical, biochemical and psychometric outcomes in minority ethnic groups with diabetes. |
| Ethics approval(s) | Local Research Ethics Committee (LREC) approval from East London and City on the 9th Nov 2005 (ref: LREC 05/Q0604/142). |
| Health condition(s) or problem(s) studied | Diabetes mellitus |
| Intervention | The intervention will have three components: 1. Professional development groups for Bilingual Health Advocates (BHAs) using a validated learning set model (in which stories about clients with diabetes form the basis of facilitated group discussion). 2. Story-sharing groups led by a BHA with support from a Diabetes Specialist Nurse (DSN). Stories about living with diabetes will form the basis of group discussions. 3. Organisational support for establishing these groups, including development and mainstreaming of patient pathways, data management, and information systems. The comparison will be referral to traditional NHS education sessions (e.g. routine nurse led education groups in either primary or secondary care, or one to one education via General Practitioner [GP] or in hospital clinic) with an interpreter if needed. |
