Abstract:
Patient-centred outcomes are significantly modified by long-term home noninvasive ventilation (NIV), but a short, self-administered, specific tool for routine clinical assessment is lacking. The aim of this study was to develop and validate the S 3 -NIV questionnaire, a short questionnaire to measure respiratory s ymptoms, s leep quality and NIV-related s ide effects. Patients with stable disease who were under long-term home NIV were recruited from three outpatient NIV services. Questionnaire development consisted of a selection of core items for analysis, followed by item reduction, validation and test–retest reliability. 338 patients completed a 22-item questionnaire. 11 items were removed because of non-scalability (n=2), redundancy (n=8) and lack of fit (n=1). The final version of the S 3 -NIV questionnaire consisted of 11 items covering two dimensions: “respiratory symptoms” (Cronbach's α=0.84) and “sleep & NIV-related side effects” (Cronbach's α=0.77). Convergent validity was high between the “respiratory symptoms” subscale of the S 3 -NIV questionnaire and the St George's Respiratory Questionnaire (rho= −0.76, p 〈 0.001), and between the “sleep & NIV-related side effects” subscale and the Quebec Sleep Questionnaire (rho=0.51, p 〈 0.001). The S 3 -NIV questionnaire had good test–retest reliability after 4 weeks (intraclass correlation coefficient=0.72). The S 3 -NIV questionnaire is a short, valid and repeatable self-completed tool for the routine clinical assessment of patients undergoing home NIV.
