BLOOD IN THE URINE, RECRUITMENT, UTI
The RCT recruited adult women (aged 20 years–88 years) presenting to UK general practice with symptoms of UTI, experiencing at least one of: pain on urination; blood in the urine; or frequency of urination; and who were able to give informed consent to take part in the RCT. All RCT participants were asked if they were willing to be contacted about participation in an interview study. In those who agreed to be interviewed, purposive sampling was used to ensure there was a range of ages within each arm of the RCT, and across a range of the GP practices where recruitment was taking place. The authors chose to interview a small number of women who had been randomised to standardised practice to learn about their experiences of producing urine samples and whether they might use a UCD in the future. Women were given written information about the interview study and the opportunity to ask questions.The women who gave consent were interviewed by telephone as soon as possible after their participation in the RCT had finished, ensuring that their experiences of urine collection were recent. The informed consent process was recorded.
