Description of intervention(s) / exposure
Automated Bladder Diary

- Participants will be asked to use a portable automated device to measure their urine over a 3 day period in addition to the usual practice of manual measuring of urine to help assess volumes passed by the patient
- The device is called "iUFlow" and is manufactured by Kesem Health Pty Ltd.
- The aim is to assess whether the use of this device provides superior results compared to patient manual measurement and paper documentation of urine volumes
- The iUFlow device is placed over the toilet bowl and collects urine as the patient voids. This is linked to a smartphone application that each patient downloads free of charge
- The application tallies the total volumes of the urine and the patient is asked to provide a rating for each void of their urgency (how pressured they felt to urinate) and incontinence (any involuntary leakage of urine that occurred)
- The intervention is the use of this device
- All patients will be using the device
- The patient will be using this device i.e. performing their own intervention
- Instructions on device use are brief and mainly relate to activation of the device. A brief instructional video is available on youtube: https://youtu.be/WHT7fRK67_A
- assessment of patients will take place by a consultant urologist
- no medical decisions will be made based on the outcome of the patients collected data from the device
- intervention will be delivered individually
- intervention will take place in the patients home as an ambulant study as this device is designed to replace a process that takes place in the patients home
- The intervention will take place over 3 days (standard length of time for bladder diary) and will only occur once. Patients will be asked to use the device continuously for 72 hours. Dose and intensity not applicable to this study
- Participants will be assigned to 2 groups through the use of random allocation of white unmarked envelopes to decide which diary type they will perform first
- Group 1 will perform the automated diary first followed by the paper diary, group 2 will perform the paper diary first followed by the automated diary.
- The 2 diaries will preferably be performed over 6 consecutive days
- No changes have been made to the design
- Adherence and fidelity to the intervention are measured outcomes of the intervention itself, so no measures were made to improved compliance as this is an outcome measure testing the effect of the device
Intervention code [1] 296848 0
Diagnosis / Prognosis
Comparator / control treatment
- All patient will complete a "traditional" paper voiding diary. This involves patients collecting their urine with each void in a measuring jug and recording the amounts of urine they pass. This amount is recorded in a "diary" and with each voiding event, the patient also writes down if they had any incontinence or if they felt a very strong urge to urinate. The volumes tallied are added up at the end of the day to assess the pattern of voiding.

Active

Outcomes
Primary outcome [1] 300731 0
- Compliance with data entry will be assesed by patient survey
- Patients will be asked how many times they went to the toilet and failed to record their urine volumes for each of the diary types. This will be a measure of "compliance" with diary procedures
- Data provided by the automated bladder diary of patients will not be used to make decisions for health care
Timepoint [1] 300731 0
72hours
Secondary outcome [1] 330735 0
- Preference of Automated Diary Compared to Traditional paper diary
- This will be assesed by survey and direct input by patients who will have a chance to explain their preference for paper vs. device use

Intervention assignment
Crossover
Other design features
- In this study participants will perform both diary types
- This study will involve half of the recruited patients completing the traditional paper diary first followed by the automated diary, with the other half of the cohort beginning with the automated diary and completing the paper diary second.
- This will be done to combat any bias in results from learned experience (getting used to doing a diary so becoming better at it) and from "diary fatigue" (becoming less compliant with completing a diary due to the length of time of effort)

Efficacy
Statistical methods / analysis
Previous research in a healthy volunteer population has shown the mean reduction of missedurinary data input events to be 2.5 for the traditional diary group and 1.1 for the device group with a standard deviation of 2 in each group. This is expected to increase based on an inflation factor of 50% in a patient population due to increased pathology. Power calculations were performed using Stata v.12.0SE (College Station, TX, USA) and showed analysis was conducted based upon an independent samples t-test, assuming statistical power of 0.80 and an alpha value of 0.05. Calculations lead to approximately 11 patients in each arm of the group. To allow for 4 patients from each arm of the study not completing or withdrawing from the study we aim to recruit 15 patients for each arm, 30 patients in total.
It is feasible that approximately 4 patients would be able to be recruited each week so an
expected recruitment period of 7-8 weeks is the aim.

Data will be entered in an Excel 2016 spread sheet (Microsoft, Redmond, CA, USA). Analysis will be performed using Stata v.12.0SE (College Station, TX, USA). Data will be defined as categorical or continuous. Distribution of continuous data will be assessed and deemed parametric or nonparametric. Categorical data will be analysed using Fishers' exact or Chi Square as appropriate. Parametric continuous data will be analysed using an independent t test or one-way ANOVA. Non-parametric continuous data will be assessed using Mann-Whitney U test or Kruskal Wallis.
