Analysis: The audiotapes will be transcribed verbatim, by the investigator or an agency used for medical transcription by KCHT, and checked for accuracy by the interviewer. The transcripts will be shared with the patient to check that they are a true representation of their intended meaning. The audio tapes will be deleted after transcription; transcripts will be anonymised using a patient identification number. The transcripts will be read with the notes taken during the interview for meaning. They will be re-read to identify themes that best capture the essential qualities of that interview. Themes from within each section of the transcript will be identified, and possible or likely connections between themes sought. A qualitative code book will be developed. The data will be coded and the codes assigned labels. The codes will be grouped into themes, interrelated and assigned to a smaller set of categories. Computer assisted data analysis software NVivo will be used to organise and support rigorous data analysis (St John & Johnson 2004).
