Study type
Interventional
Description of intervention(s) / exposure
Education to newly diagnosed patients with glaucoma about the nature of the condition, treatment and daily management of treatment regimens.

Education is administered on individualised one-to-one sessions over the telephone via trained health professionals. This is a one off telephone session lasting 30 minutes. This telephone session is followed up 2-3 days later by a mail-out package of information booklets regarding the nature of glaucoma and some common issues regarding its treatment. The overall duration of the intervention period is 4 weeks, during which the telephone session and the mail-out occurs in the first 1-2 weeks. Completion of the telephone interview and mail out is recorded by study staff to ensure adherence to the intervention for all cases in the intervention arm of the study.

Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation of the randomised sequence will be recorded onto individual sheets of paper sealed in an opaque envelope; this will be the only record of the sequence. The envelopes will be opened by the study investigators individually and sequentially following enrolment of the study, and prior to data collection, and will be used to sequentially assign participants to the study groups.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation will occur using a randomly generated sequence allocating participants on a 1:1 ratio. This sequence and the randomisation process will be concealed from the investigators enrolling participants. A computerised process will be used to generate a random sequence of numbers that fall into 2 categories; these will be respectively assigned to the control and treatment arms.
Masking / blinding

Statistical methods / analysis
Power calculations were performed as follows. A significance level (alpha) of 5% and a power (1- beta) of 80% were chosen for two-tailed, non-paired student t test to compare final results in the glaucoma knowledge questionnaire. Predicted mean scores and standard deviation for the two groups were based on previous data.

Based on previous data the effect of education administration can be estimated to raise the score on the Glaucoma Knowledge Questionnaire by 9-12%.

Summary
Brief summary
We aim to investigate the impact of a telephone-based education schemes for newly diagnosed patients with glaucoma. Newly diagnosed glaucoma patients treated with drops are randomised to either the control or treatment arm. All have questionnaires administered over the telephone at the study outset and at completion, 4 weeks following the outset. The questionnaires include a Glaucoma-knowledge Questionnaire, an anxiety scale and an Eye Drop Satisfaction Questionnaire.

Patients in the intervention arm will receive the education in the first week of the study period. THose in the control arm will only receive that information once the study is completed. We will measure differences in changes of scores from outset to conclusion of the study looking for differences between the intervention and control groups.
