Assesment on health-related quality of life in elderly patients with stable chronic obstructive pulmonary disease / 中华老年医学杂志

ABSTRACT

Objective To assess the health-related quality of life in elderly patients with stable chronic obstructive pulmonary disease(COPD).Methods The patients were collected from the outpatient department,a tertiary hospital in ShaanXi Province.The demographic characteristics such as age,gender,weight and height were collected.Spirometry was performed for every patient after salbutamol 400 μg was inhaled.6-minute walk test was done according to the guidelines which developed by American Thoracic Society in 2002.Four questionnaires,including COPD Assessment Test (CAT),Clinical COPD Questionnaire-week Version (CCQ),St George's Respiratory Questionnaire for COPD Patients (SGRQ-C) and Chronic Respiratory Questionnaire-Self Administered Standardized Activities-First Administration Version (CRQ-SAS),were answered by every participant.Results Totally 90 participants were enrolled between September 2013 and September 2014.75 cases(83.3％) were male and 70 cases (77.8％) were smokers or ex-smokers,the mean age was (67.8±9.7)years,and the mean educational history was (8.9±3.0)years.The mean body mass index was (23.3 ± 3.6) kg/m2,and the mean post-brochodilator FEV1 was (51.2 ± 18.7) ％ predicted.The average 6-minute walk distance was (424.5 ± 99.1) meters.The average scores of CAT and CCQ were(20.4±6.9) and (2.4±0.8),respectively.The mean SGRQ-C score was (38.5 ± 16.2).The symptoms,activity and impacts average scores of SGRQ-C were (64.3± 18.8),(45.1 ±21.3) and (25.7 ± 16.1).For CRQ-SAS,the average scores of dyspnea,fatigue,emotional function and mastery were (2.9±1.3),(2.9±1.1),(3.0±1.1) and (2.9±1.1),respectively.There was a weak correlation between FEV1 and each questionnaire scores.There was a moderate correlation between 6-minute walk distance and SGRQ-C,CCQ and CRQ-SAS.However,there was a weak correlation between CAT and 6-minute walk distance.For 6-minute walk distance,activity score of SGRQ-C,impacts score of SGRQ-C and history of coronary artery disease were independent influencing factors.For BODE index,activity and impacts score of SGRQ-C were independent influencing factors.Conclusions CAT,CCQ,SGRQ-C and CRQ-SAS are suitable to assess health-related quality of life for elderly patients with stable COPD,among four questionnaires,SGRQ-C is the best one.
