Validation of the InCaSaQ, a new tool for the evaluation of patient satisfaction with clean intermittent self-catheterization

AbstractAimsIn neurourology, the choice of catheter is of paramount importance. At the time of our study, no simple validated questionnaire has been published, evaluating patient satisfaction with the use of urinary catheters. Our objective was to construct and validate a specific tool referred to as the Intermittent Catheterization Satisfaction Questionnaire (InCaSaQ), for the purposes of evaluating patient satisfaction with intermittent self-catheterization.MethodsA simple tool was developed and validated in a neurourology referral centre, with 113 patients affected by a neurological bladder condition, between November 2011 and February 2012. Eight items, separated into four categories (“packaging”, “lubrication”, “catheter itself”, “after catheterization”) were selected. The mean score obtained with the eight-question questionnaire was calculated for each patient. Face validity was evaluated. Reliability based on internal consistency and test-retest reliability using the intraclass correlation coefficient (ICC) was carried out.ResultsThe patients’ comprehension and acceptance of the questionnaire were good. The questionnaire appears to have been well designed, with a significant Cronbach's alpha coefficient, and the ICC demonstrated good test-retest reliability.ConclusionsThe InCaSaQ was found to be a valid tool for the evaluation of patient satisfaction with a urinary catheter. It is thus possible to compare the comfort and effectiveness of different types of catheter, and to objectify the need to change the type of catheter, in cases where patients express their dissatisfaction
