Neurogenic bladder symptom score short form's minimal important improvement is 1.8 points
The Interpretability of the Neurogenic Bladder Symptom Score.
To define mild, moderate and severe symptom categories of the neurogenic bladder symptom score (neurogenic bladder symptom score) and neurogenic bladder symptom score-short form (SF), and to calculate the minimal clinically important difference (minimal clinically important difference) of the neurogenic bladder symptom score-SF.
We used existing datasets from the original neurogenic bladder symptom score validation study (n = 230 patients with spinal cord injury (spinal cord injury), multiple sclerosis, and spina bifida), and a large cross-sectional study of people with spinal cord injury (n = 1479) who completed the neurogenic bladder symptom score.
Using the median/interquartile range of the associated neurogenic bladder symptom score domain score of people who were in the moderate category of the ICIQ-UI, IPSS, and the SCI-QOL Bladder complications, we calculated the severity categories for the neurogenic bladder symptom score total score: 0-32 (mild), 33-48 (moderate), and 49-74 (severe).
These score categories produced significantly different neurogenic bladder symptom score scores in 29/32 comparisons in four different study populations.
The global bladder problem had good agreement with each domain's categorical scale.
We have determined interpretability ranges for the neurogenic bladder symptom score and neurogenic bladder symptom score-SF. This can help interpret patient and clinical study results.
