Background:
To evaluate the effect of a humidity detector device on the quality of life of patients with urinary incontinence IU.
Method:
Quasi-experimental study: a series of ten cases followed for a month. The devices were placed and the questionnaires filled in before and after using it for at least ten hours a day during a month. Health related quality of life was assessed through the questionnaires for IU convalidated and adapted to our specific environment: Urogenital Inventory Distress (UDI) and Incontinence Impact Questionary (IIQ). An improvement of 58 points by a four option Likert scale was considered a positive impact in the quality of life (IIQ). The scores obtained in UDI and IIQ are described before and after use the device and paried T test and Wilcoxon sign test were carried out to compare the scores obtained in each instance. The capacity to detect a difference of 58 points on the UDI scale was calculated (minimum relevant difference). A binomial test was undertaken to ascertain a probability of achieving an increase in the above mentioned index which would exceed the clinical relevance threshold.
Results:
Average increase in IIQ improvement: x = 5.48 (Std Error = 20.43) 95% CI = -34.56 to 45.56. Average increase in UDI improvement: x = -11.87 (Std Error = 20.70) 95% IC = -52.45 to 28.70. The power of the analysis to detect as relevant a difference of a 588 point increase in IIQ 71.1% and probability of obtaining a relevant improvement in the questionnaire IIQ 10% (IC 95%) 0% to 39.4%.
Conclusions:
A negative impact in the Quality of Life due to frequent changes of incontinence pads.
