ObjectivesThe Severe Respiratory Insufficiency (SRI) questionnaire is the best assessment tool for health-related quality of life in patients with chronic obstructive pulmonary disease (COPD) receiving non-invasive positive pressure ventilation (NIPPV). This study aimed to translate the SRI Questionnaire into Chinese and to validate it.DesignProspective validation study.Setting and participantsA total of 149 participants with chronic hypercapnic COPD receiving NIPPV completed the study.MethodsThe SRI questionnaire was translated into Chinese using translation and back-translation. Reliability was gauged using Cronbach’s α coefficient. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess construct validity. Content validity was confirmed by evaluating the relationship between the score of each item and the total score of the relevant subscale.ResultsCronbach’s α coefficients for each subscale and summary scale were above 0.7. Using EFA, one factor was extracted from the anxiety and summary scales and two factors were extracted from the remaining six subscales. Based on the EFA results, subsequent CFA revealed a good model fit for each subscale, but the extracted factors of each subscale were correlated. Content validity was confirmed by the good relationship between the score of each item and the total score of the relevant subscale.ConclusionThe Chinese version of the SRI questionnaire is valid and reliable for patients with chronic hypercapnic COPD receiving NIPPV in China.Trial registration numberNCT02499718.

Objective: To determine the outcome of early use of non-invasive positive pressure ventilation (NIPPV) in Pakistani patients with acute exacerbation of chronic obstructive pulmonary disease. Methods: This descriptive study was conducted at Shifa International Hospital Islamabad from April 2015 to January 2017. A total of 120 patients with acute exacerbation of chronic obstructive pulmonary disease receiving NIPPV alongside standard therapy were included in the study. The patients were clinically assessed before starting on NIPPV. The parameters of respiratory rate, pH and paCO2 were monitored and NIPPV was given for six hours to evaluate clinical outcomes and analyze the factors predicting failure (requirement of mechanical ventilation and mortality). Frequency and percentages were calculated for qualitative variables while Mean and Standard Deviation for quantitative variables. Chi-square and t-test were used to see differences in pre and post NIPPV arterial blood gases. Results: Patients’ mean age was 58.88±10.09 years. Males were 88 (73.3%) and females were 32 (26.7%). The mean respiratory rate was 24±1.45 per minute before and 17.96±1.35 per minute after NIPPV (p < 0.00001). The mean pH before NIPPV was 7.27±0.04 and afterwards 7.38±0.02 (p < 0.00001). The mean pCO2 was 61.87±9.60 mm of Hg before and 57.46±6.79 mm of Hg after NIPPV (P < 0.0003). Twenty Four (20%) patients required invasive ventilation of which 19 (15.8%) patients could not survive. Conclusions: There was remarkable improvement in the arterial blood gases after NIPPV. However, the high mortality rate and significant number of COPD patients requiring mechanical ventilation necessitates further investigation into our population. doi: https://doi.org/10.12669/pjms.35.6.857 How to cite this:Ishfaq N, Gul N, Zaka N.
