Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The device used to facilitate the GTN spray has been called the GT'NHaler. The device is used to assist with the administration of glyceryl tri-nitrate sublingual spray in patients with angina and impaired manual dexterity caused by arthritic, neuromuscular or other disability. The device consists of a tube into which the GTN spray canister is inserted. A l lever attached .to the top of the device is used by the patient to provide downwards pressure to the top of the canister thereby activating administration of the GTN spray. The device will be used every time the participant's standard care glyceryl tri-nitrate sublingual spray is administered over the 1 month period of the study. The patient's use of the device and their opinions on its effectiveness and ease of use will be recorded in a questionnaire booklet.

Efficacy
Statistical methods / analysis
Analysis of patient written responses in questionnaire. No statistical power calculations were carried out as the study is a qualitative assessment of the GTN device, making statistical assumptions difficult to construct. The number of 20 subjects with 30 days of responses/observations (600 data points) was considered adequate to provide information that could be used to adapt or modify the GTN device. .
