Aims

In this study, we aim to demonstrate the feasibility of using IUFlow in our
local population. Our hypothesis is that an automated bladder diary will
improve compliance and is a preferred method of choice for our patients.
Having multiple uroflow readings will also help in the diagnosis and
management of our patients with lower urinary tract symptoms.

Background

A voiding diary is an important diagnostic tool to assess urinary tract
symptoms. Traditional paper based voiding diaries have a notoriously
poor compliance rate. iUFlow is a new portable device allowing to
measure uroflowmetry in a patients own home and electronic recording
of a bladder diary.

Methods

Patients in our specialist outpatient clinics were assessed and those who
warranted a bladder diary as part of the work up were recruited into our
study. Patients were offered an option of joining this study versus the
traditional paper bladder diary. At follow up, a likert-scale questionnaire
was administered looking at 3 main components: Confidence in usage,
ease of usage and preference in choice.

Results

A total of 13 patients were recruited during the study period. 11/13 (85%) of
patients reported that the device was easy to use. 9/13 (69%) of patients
preferred the IU device and 1/13 (7%) of patients preferred the paper diary.
Completion rate was 100%.

Conclusion

The UI device is an easy to use and convenient alternative to the paper
bladder diary. It allows for easy charting of a bladder diary which can increase
patient compliance, as well as having the advantage of measuring
uroflowmetry in the patients own home which can open the doors for
teleconsultations and remote monitoring for these patients.

Lessons Learnt

Budget for import fees if bringing in product from
overseas.
Start HSA approval process early.
Local population are adept at apps despite age.
Involve stakeholders early (nursing, research coordinator,
medical officers etc.)
