To enhance the value of the integration between our qualitative and quantitative methods, we developed a joint display to support the interpretation and reporting of this mixed methods study. 30 Key survey findings were integrated with the themes and subthemes identified from the interviews to facilitate the interpretation of the **data** and refine our themes. The integrated findings from the survey and the interviews were summarised and sent to all survey and interview participants for their review and feedback. Additional details regarding the methods can be found in online supplemental file 3.
