PatIent exPeRiences and prEFerence of trEatment foR Multiple Myeloma

People can receive many lines of treatment for multiple myeloma. The investigators would like to understand more about the experiences of people being treated for multiple myeloma including what matters most to participants when considering treatment options, how participants experiences have differed with different treatments and if participants have any treatment preferences. Patients at The Christie who have received five or more lines of treatment for Multiple Myeloma will be eligible to take part in this study. Participants will be asked to take part in an interview which should take approximately 30 minutes to an hour. During the interview, participants will be asked questions regarding their experiences and preference for treatment. Interviews will be conducted either in person or over the phone depending on patient preference. The interviews will be recorded by the research team using a Dictaphone and transcribed by an external transcription service called 1st Class Secretarial. The transcripts of all participant interviews will be reviewed by members of the research team and experiences will be identified and described.

• Patient Interview (Other): Participants will be asked to take part in a 30-60 minute interview to understand their treatment experiences and preferences.

Primary outcomes

• Patient Experience and Preference [30-60 minutes]: The interview will explore the experiences of people receiving treatment for multiple myeloma and understand what matters most to them when making treatment decisions.

Secondary outcomes

• Treatment and Preference Differences [30-60 minutes]: The interview will explore how experiences have differed across different lines of treatment and determine if people with multiple myeloma have any preferences for particular treatments.
