Clinical Trial Summary

The primary aim of this project is to create an online weight management tool (Physical activity, weight management and cognitive behavioral therapy) to prevent significant weight gain following kidney transplantation. Designing the online interactive weight management resource for kidney transplant patients will involve patient and health care professional input through Qualitative methodology such as 'Think-Aloud' interviews and one-to-one semi-structured interviews. This online resource will be called "exertion" and will be created by the research team, with technical support from the Software Company (SPIKA).

Results from this study will refine the resource, and lead to a study application for a randomized controlled feasibility trial where we plan to test the "exertion" online application. Therefore this project has potential to influence clinical practice for kidney transplant recipients. It will allow patients, who may not have routine access to physio or dietetic input to address weight gain with support. A study flow chart summarizing the project can be found below.


Clinical Trial Description

This study is a qualitative study and intervention planning study to create and refine an online resource for weight management in new kidney transplant (KTx) recipients, which will be named "exertion".

Objectives and hypothesis:

The aim of this qualitative study is to use qualitative methods to create and refine a weight management, exercise/ physical activity online resource for patients with kidney transplant recipients.

This study involves data collection via:

- Think-aloud interviews- 5 KTx patients and 2 Health Care Professionals (HCP) working in the transplant team will have recorded think aloud interviews using the resources. Other participants will be exposed to the resource during a routine lab session.

- Semi-structured interviews of transplant HCP's and KTx recipients.

- Demographic data including age, gender, occupation, smoking history, medical history, medication lists and baseline body weight (kg).

- Website/ resource log in data

- Field notes and observations from Think Aloud interviews, lab sessions and semi-structured interviews

The investigators aim to recruit 10 new kidney transplant recipients and 5 transplant health care professionals to explore the following themes through 'Think-Aloud' interviews:

- The functionality of the "exertion" online resource for KTx recipients

- The functionality of the "exertion" online resource from a HCP perspective

- KTx participants interpretation of the "exertion" modules and resource as a whole

- HCP participants interpretation of the "exertion" modules and resource as a whole

- Thought processes involved to use the "exertion" application

- Recommendations from participants

- Likes/dislikes

- Barriers/ easier to use sections

- Highlight individual differences in the use of the "exertion" resource

The investigators aim to explore the following themes through semi-structured individual interviews:

- What components of the online resource (exertion) are helpful/ unhelpful from a kidney transplant perspective?

- What components of the online resource are helpful/unhelpful from a kidney transplant HCP perspective?

- Are there any difficulties/ barriers participating in the study?

- And are they what were expected or different?

- Patients experiences and learning using the online application, and when the changes were noticed

- Anything missing/ they would recommend adding to the application

Statistical Analysis:

Baseline demographics of the participants will be described using summary statistics. Continuous variables will be summarized using the mean and standard deviation (SD) if approximately normally distributed. Continuous variables that are not normally distributed will be summarized using the median and IQR.

Qualitative analysis: Data will be collected through in-depth feedback about the online intervention materials; field notes, individual interviews and 'Think-aloud' interviews. 'Think-aloud' interviews will be used to elicit participants' reactions to sessions of the online intervention; participants will be observed and asked to comment aloud on reactions to every aspect of the different sessions. Semi-structured interviews will explore participants' overall impressions of the online intervention. These qualitative techniques will allow for themes and sub-themes to emerge. The website will be designed to record user entries, and observational field notes about participants' use of the intervention will also be collected. Individual interviews will be transcribed verbatim and analysed using an inductive thematic analysis approach (17), informed by techniques of grounded theory (15), including line-by-line open coding grounded in data and constant comparison of all instances of codes. Deviant case codes will be employed to ensure that perspectives that diverge from dominant trends are not overlooked. ;
