Design outcomes

Primary

MeasureTime frame
Any catheter blockage requiring intervention up to 24 months post randomisation, from the question ‘Have you had any catheter blockages since we last spoke to you?’ from patient-reported monthly phone call CRF (monthly for 24 months) (Intervention is defined as any of the following: unplanned catheter removal or change or washout performed by the participant/ designated person or required unplanned visits to/from any healthcare provider, or hospital admission)

Secondary

MeasureTime frame
Current secondary outcome measures as of 22/04/2022: 1. S-CAUTI requiring antibiotics use from the questions ‘Have you had a urine infection since we last spoke to you?’ and ‘How many infections required antibiotics?’ from patient-reported monthly phone call CRF (monthly for 24 months) 2. Duration of LTC in situ, catheter change due to other reasons than blockage, discontinuation of LTC use; from the questions ‘Has there been discontinuation of long-term catheter use?’, ‘For the (reported problem), what treatment did you have?’ and Answers ‘Catheter change’ from patient-reported monthly phone call CRF (monthly for 24 months) 3. Adverse events; where participant has reported a treatment in the patient-reported monthly phone call CRF (monthly for 24 months) and the question of the clinical team is asked ‘Is this a SAE? Please tick’ 4. Hospital admissions, GP/nurse outpatient visits for catheter-related complications from the questions ‘Since we last spoke to you, have you had to stay in hospital overnight for any of the problems related to your catheter?’, ‘For the (reported problem), where did you have treatment or a consultation with a doctor or nurse?’ and possible answers ‘GP at home, Nurse at home, care home staff, GP at surgery, Nurse at practice, Self/informal carer, Staff at hospital’ from patient-reported monthly phone call CRF (monthly for 24 months) 5. Generic quality of life assessed by EQ-5D-5L17 (EuroQol questionnaire – 5 dimensions – 5 levels) patient-reported questionnaire; Timepoint(s): 0, 6, 12, 18, 24 months post-randomisation 6. Condition-specific quality of life assessed by ICIQ-LTCqol18 (International Consultation on Incontinence Modular Questionnaire – Long Term Catheter quality of life) patient-reported questionnaire; Timepoint(s): 0, 6, 12, 18, 24 months post-randomisation 7. Adherence to allocated interventions,events changing type and/or frequency (or cessation) of catheter washouts in arms A and B and rates of commencing on prophylactic wa
