Effect of motivational interviewing health education on self-management behavior and lung function of elderly patients with stable chronic obstructive pulmonary disease in the community / 中华老年医学杂志

ABSTRACT

Objective To explore the effects of motivational interviewing health education on the self-management behavior and lung function of the community-elderly patients with stable chronic obstructive pulmonary disease(COPD).Methods Totally 215 elderly patients with stable COPD from Xi'an community were enrolled by convenience sampling,and the patients were randomly divided into control (n=108) and experimental group (n=107) using the random number table.The patients in the experimental group received motivational interviewing health education for 6 months in addition to usual health education for both groups.The two groups were examed by self-management behavior (smoking,respiratory function exercises,muscle exercises,home oxygen therapy,medication adherence and inhaled drugs method) and lung function before and after intervention.Results In the experimental group,smoking cessation rate [72.9％ (78 cases) vs.84.1％ (90 cases),x2 =7.40],respiratory-function exercises (often) [16.8％ (18 cases) vs.84.1％ (90 cases),x2 =99.35],muscle exercises (often) [30.8 ％ (33 cases) vs.87.0％ (93 cases),x2 =69.49],frequent home-oxygen therapy [9.3％(10 cases) vs.35.5％(38 cases),x2 =30.50],medication following the doctor's advice [36.5％(39 cases) vs.86.9％ (93 cases),x2 =57.67]and right inhaled-drugs method [44.9％ (48 cases) vs.95.3％(102 cases),x2 =65.00]were much greater than those before intervention (all P＜0.05).Lung function including vital capacity (VC) [(2.53±0.41) L vs.(2.66±0.58)L,t =-2.62],forced vital capacity (FVC) [(2.51 ± 0.45) L vs.(2.64 ± 0.60) L,t =-2.56],forced expiratory volume in one second (FEV1) [(1.59±0.23)L vs.(1.74±0.47)L,t =-2.75],FEV1％ [(63.6±22.8) ％ vs.(73.5±20.9)％,t =-3.38]were significantly improved after 6 months as compared with those before intervention (all P ＜0.05).However,only right inhaled-drugs method was significantly greater than that before intervention in the control group [41.7 ％ (45 cases) vs.61.1％ (66 cases),x2 =8.17,P＜0.05].Conclusions Motivational interviewing health education may improve the self-management behavior and lung function of elderly patients with stable COPD,and it serves as an effective disease-management strategy.
