Continence Matters Bladder Diary: Clinician Information & Resource Guide

Welcome to the Continence Matters digital Bladder Diary referral resource. This clinical tool has been designed by specialists to eliminate the errors, illegible handwriting, and high drop-out rates associated with traditional paper bladder diaries.

How to Instruct Your Patients

For the most accurate clinical diagnostic results, advise your patients to follow these steps:

Open the Link on a Mobile Device: Ask them to visit https://bladderdiary.continencematters.com on their smartphone and save it to their home screen for rapid, convenient access throughout the day.

Keep a Measuring Jug by the Toilet: Recommend they purchase or dedicate a simple plastic household measuring jug to measure their output.

Select the Correct Mode: 'Intake & Output', or if you only require voided volumes, instruct them to switch the app to "Output-Only" mode in the settings.

Export and Email the PDF: Once 3 days of data are completed, they click the "Share / Export" tab and enter their name and date of birth. These are printed on the report header only and are never stored in the app. They then generate the PDF report and email it directly to your clinic, or print it for their next appointment.

Health Professionals: Frequently Asked Questions

Why should I recommend this digital bladder diary over paper?

This digital diary is designed to simplify patient compliance and clinical analysis. It features:
Zero-friction data entry: Patients can log entries in under 10 seconds via mobile.
Automatic time-stamping: Captures precise timing without requiring manual clock-reading.
Incontinence & Catheter tracking: Seamlessly integrates leak severity, pad/linen changes, and Intermittent Self-Catheterisation (ISC) volumes.
Instant clinical math: Instantly calculates nocturnal volumes, fluid balance, averages, and NPI percentages, eliminating clinical spreadsheet calculations.
Accessible by design: every field and control is labelled for screen readers (VoiceOver, TalkBack), supporting blind and low-vision patients.

How do I interpret the Nocturnal Polyuria Index (NPI)?

The Nocturnal Polyuria Index (NPI) is calculated as the Total Nocturnal Urine Volume divided by the 24-hour Total Urine Output.
Sleeping Period: The diary uses the sleep schedules entered by the patient to precisely isolate nighttime voids (including the first void after waking).
Clinical Significance: An NPI greater than 33% (or greater than 20-33% in younger adults) indicates Nocturnal Polyuria, helping you differentiate between global polyuria, reduced bladder capacity, and nocturnal polyuria.

What clinical parameters are tracked in the report?

The generated PDF report provides a clean, printable dashboard featuring:

Total 24-hour fluid intake and voided output.
Daytime vs. Nighttime void distributions.
Maximum, minimum, and average voided volumes.
Total catheterised (ISC) volumes, frequency, and maximums.
Graded wetting episodes (None, Mild, Medium, Severe, Bed-Wetting).
Pad changes (Small, Medium, Large, XL, Pullups) and clothing/linen changes.
A high-resolution bar chart showing daily intake versus output.
An organised, chronological timeline of every log entry.

How does the patient share the report with me?

At the end of the 3-day logging period, the patient goes to the "Share/Export" tab. They can generate a beautifully formatted PDF report. They can:
Send the PDF directly to your secure clinic email address.
Print a physical copy to bring to their next appointment.
Copy a plain-text clinical summary to paste into a telehealth portal or email.
Reports are identified by the name and date of birth the patient enters at export, which appear on the report header; if a report arrives without them, ask the patient to resend with their details typed into the email body.

How is patient data protected?

The diary is anonymous by design and built on privacy-by-design principles: no identifying information is collected, data is kept to the minimum needed, stored securely, and automatically deleted.
No accounts, no identity: Patients never register or log in, so no names, dates of birth, email addresses, or contact details exist anywhere in the system. At export, a patient may optionally type their name and date of birth so the report can be identified by your clinic. These are only printed on the exported report itself and are never stored by the app.
Anonymous cloud storage: Entries are stored under a randomly generated identifier in a secure, encrypted cloud database (Google Firebase, hosted in Australia). Because no identifying information is ever collected, entries cannot be linked to an individual patient.
Automatic deletion: All entries and sleep schedules are automatically and permanently deleted after 30 days.

Can Continence Matters access my patient's data?

No. Continence Matters never views, analyses, sells, or shares patient entries, and no advertising or analytics companies have access to them. Because the diary collects no identifying information, there is no patient-identifiable data to access even in principle. When a patient exports their report, the PDF is generated on their own device and sent by the patient directly to your clinic through their own email, it never passes through Continence Matters.

Extra Features

Total Bladder Volume Logic (Void + ISC): If a patient records both a natural void and an ISC catheter volume at the same time, the app highlights both values and automatically displays the Total Bladder Volume (Voided Volume + Catheter Volume = Total Bladder Volume).

Interactive Catheter (ISC) Tracker: The clinical statistics tab now features a dedicated Catheter (ISC) Tracker card (when ISC is used) showing daily catheterisation volumes and detailed parameters (catheterisation count, average catheter volume, maximum residual).

Multi-Channel Bar Charts: The bar charts on the dashboard dynamically render separate bars for Voided volume versus Catheter (ISC) volume per day for superior visual analytics.
