Abstract:
Objective To evaluate the efficacy of telephone interviews on the quality of life of patients with chronic Keshan disease.Methods Totally 120 cases of chronic Keshan disease patients with chronic heart failure and NYHA classification of Ⅱ-Ⅳ were enrolled among the 181 patients with chronic Keshan disease,which confirmed by case search in Heshui County and Zhengning County in Qingyang City,Gansu Province in 2015,general demographic and clinical data were collected.According to the principle of random number table grouping,these 120 patients were randomly divided into a intervention group (n =60) and a control group (n =60).Both groups were given the conventional therapy and encouraged to inquiry or given regular outpatient medical follow-up.The patients in the intervention group received telephone interviews regularly for 6 months,with a interview frequency once a week in the first month,once every two weeks in the second and third months and once a month in the fourth,the fifth and the sixth months,with about 15 to 20 minutes interviews each time.Meanwhile there was no telephone interviews in the control group.At the begining of study,and after 3 months and 6 months of study,quality of life scores were scored according to the Minnesota Heart Insufficiency Scale (MLHFQ).The scores included total quality of life,physical field scores,emotional field scores,and other field scores.The lower the score,the higher the quality of life.Results After 3 months of telephone interviews,the emotional domain score of the intervention group (10.16 ± 4.58) was lower than that of the control group (13.10 ± 5.37,P ＜ 0.05).After 6 months of telephone interviews,the patients in the intervention group (35.60 ± 16.07,6.67 ± 4.01,13.16 ± 4.13) had significantly better quality of life than those in the control group (57.19 ± 14.97,12.43 ± 5.29,18.94 ± 6.68),with lower total points of life quality,emotion area and other area scores.The differences between the two groups were statistically significant (P ＜ 0.05).Conclusions Telephone interviews may promote the quality of life for patients with chronic Keshan disease.It is an effective way in enhancing the ability of chronic Keshan disease management.
