Plain English Summary

Background and study aims
Glaucoma is an eye condition where the nerve that connects the eye to the brain is damaged, leading to vision loss. Once sight is lost through glaucoma it cannot be got back so stopping sight loss in patients with glaucoma is important. One way in which doctors, opticians and nurses can help patients is to teach them about their glaucoma so that patients know how and have the skills to look after their eyes in the best way possible. This study aims to find out how much information on glaucoma is given to patients in glaucoma clinics held by nurses and how nurses could best give information about taking care of their eyes. The aim of the study is to

Who can participate?
Adults aged 18 and older who have glaucoma.

What does the study involve?
Participants attend two session education programmes on week apart. The educational sessions include how to best take care of their glaucoma. Participants are assessed for their knowledge of glaucoma and their adherence to treatment before and after the educational programmes.

What are the possible benefits and risks of participating?
Participants will benefit from having learnt more about glaucoma and what they can do to help themselves. Nurses will benefit as they will expand their range of patient teaching options. There are no risks of this study apart from the burden of time for the nurses in learning and giving the patient classes and to the patients in terms of finding the time to attend.

Where is the study run from?
1. Royal Liverpool University Hospital (UK)
2. New Cross Hospital (UK)
3. Abergele Hospital (UK)

When is the study starting and how long is it expected to run for?
February 2011 to December 2014

Group based patient education delivered by nurses to meet a clinical standard for glaucoma information provision: The G-TRAIN feasibility study


GTrain study

Study hypothesis

The aim of this study is to understand current provision of information during routine nurse-led glaucoma consultations, to investigate if it is possible to deliver patient information in-line with a clinical standard by training nurses to deliver group based education in multiple hospital sites, and to explore the acceptability of group based education to nurses and patients compared with usual information provision in consultations.

People diagnosed with glaucoma within the previous 12 months attending a regional ophthalmology clinic in the North West of England are recruited. Participants receive a group based patient education called "GTrain" which has been developed to train healthcare professionals so that they can deliver group based education to patients about glaucoma which will help them to manage their condition appropriately. The programme is a two-session education programme is delivered one week apart. A combined adult learning and health needs approach to education is taken.

Registered nurses who had received training in the delivery of the intervention deliver the programme. The training consisted of a two day interactive workshop in which the structure and content of the ‘Get a grip on your glaucoma’ course was covered. Participants receive the programme face to face in a group. Participants have the opportunity to get individualised advice offered at the end of the group intervention. The intervention was delivered in a room on the hospital site of where the nurses worked.

Outcomes measured were knowledge of glaucoma, self-report of adherence, illness perception, beliefs about medicines, patient enablement, and general health. Adherence was also measured objectively using a Medical Events Monitoring System device.
