Question 1

How is the ISI score calculated?

Accepted Answer

The ISI score is calculated by multiplying your frequency score (0-4) by your amount score (0-3). This produces a severity index ranging from 0 to 12. The multiplicative approach means that both frequent and large-volume leakage results in the highest severity scores.

Question 2

What severity levels does the ISI measure?

Accepted Answer

The ISI classifies incontinence into four severity levels: Slight (1-2), Moderate (3-6), Severe (8-9), and Very severe (12). A score of 0 indicates no leakage. Note that some scores (7, 10, 11) are not achievable due to the multiplicative scoring method.

Question 3

How often should I take this assessment?

Accepted Answer

For treatment monitoring, the ISI is typically administered at baseline (before treatment begins) and at regular follow-up intervals such as monthly or at each treatment visit. This allows you and your provider to track changes in incontinence severity over time.

ISI: Incontinence Severity Index (Sandvik Index)

Take the Incontinence Severity Index to measure the severity of urinary leakage using just two questions about frequency and amount.
