Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be assessed by the pre-operative cardiac education nurse for inclusion or exclusion into the study. Following identification for inclusion the pre-op education nurse will randomly remove an envelope from a box provided, this envelope will have an ID Number printed on it which will become the participants ID No for the study. Participants will be required to complete the questionnaires inside the envelope and at various stages throughout the study process . Participants will be provided with an information sheet which outlines the studies purpose and aims. Participants will be required to sign a consent form in the presence of the pre-op education nurse who will also witness this form. ID numbers will be used on all documentation and drugs thorughout the trial process to assure anonymity and confidentiality of data. The participant (if in the intervention group) will begin drug (NRT) treatment following surgery and transfer to the cardiac step-down unit (approximately 24 hrs or more following surgery).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation of participant ID numbers will be achieved by a computer generated randomisation sequence using Microsoft Excel. The envelopes that contain the questionnaires will have the ID number printed on the exterior. These envelopes will be placed within a box for the cardiac pre-op education nurse to randomly remove during recruitment. The ID number of which has already been randomised to either the control or intervention group.
