Résumé
Objective To investigate the effectiveness of the SF-36 health survey questionnaire used to investigate the quality of life (QOL) of the patients undergoing tibial bone transport.Methods Reliability analysis,correlation analysis and validity analysis were performed to evaluate the reliability and validity of the SF-36 scale.According to treatment time,94 patients who underwent tibial bone transport were divided into 3 groups:group A were 30 patients who had just started bone transport,group B 43 patients who had completed bone transport and removal of external fixation within 2 years,and group C 21 patients who had completed bone transport and removal of external fixation beyond 2 years.A mean comparison of items in the SF-36 scale was further carried out.Results The questionnaires were completed well.The Chonbach α indexes of all the items were more than 0.8,showing good reliability of the scale.Most of the correlation coefficients were almost or more than 0.5,indicating acceptable content validity of the scale.The QOL of the patients undergoing tibial bone transport was differentiated from that of normal people,proving good discriminant validity of the scale.Groups B and C obtained significantly better scores in all items of the scale than group A (P ＜ O.05).Group C scored significantly higher in physical functioning (PF) and role-emotional (RE) than group B (P ＜ 0.05),but there were no significant differences between the 2 groups regarding other items of the scale (P ＞ 0.05).Conclusions With good reliability and validity,the SF-36 health survey questionnaire can be used to assess the QOL of the patients undergoing tibial bone transport.The treatment of bone transport in the tibia can significantly and durably help improve the QOL of the patients.
Résumé
Objective To study the relationship between the cardiac markers in ST-segment elevation myocardial infarction (STEMI) and quality of life (QOL) six months later.Methods N-terminal pro-B-type natriuretic peptide (NT-proBNP),cardiac troponin I (cTnI),creatine kinase isoenzyme-MB (CK-MB)and myoglobin(Myo) was tested in 76 patients with STEMI on admission(0 h) and 24 h after admission.QOL six months later was evaluated by using the SF-36 health survey questionnaire.The relationship between the cardiac markers and QOL was analyzed by multivariate linear regression analysis.Results The total SF-36 scores and the scores of physical function,body pain and general health showed negative linear correlation with NT-proBNP on admission (0 h) and 24 h after admission (P ＜ 0.05).The total SF-36 scores and the scores of physical function and body pain showed negative linear correlation with cTnI on admission (0 h)and 24 h after admission (P ＜ 0.05).The total SF-36 scores and the scores of body pain showed negative linear correlation with CK-MB on 24 h after admission (P ＜ 0.05).The scores of vitality showed negative linear correlation with Myo on admission (0 h) (P ＜ 0.05).Conclusion The higher levels of NT-proBNP,cTnl and CK-MB indicate the lower QOL six months later.
