Abstract:

Objective To invest the quality of life（QOL）of elderly patients with type 2 diabetes mellitus（T2DM）and coronary arteries atherosclerosis（CAAS），analyze the major influencing factors and put forward nurs⁃ing countermeasures. Methods To gather clinical records of our 120 hospitalized elderly patients with T2DM andCAAS and conduct survey with general questionnaire，diabetes⁃specific quality of life（DSQL）and summary ofdiabetes self⁃care activities（SDSCA）. QOL⁃related factors are filtered with T test，variance test and correlationanalysis，and factors influencing patients′ QOL are analyzed with multiple linear regression equation model. Drawthe receiver operating characteristic（ROC）diagram to select indicator for predicting QOL. Results The DSQLscore of the 120 included subjects were（70.97 ± 21.41），among which the QOL of psychological dimension is theworst；and the SDSCA score was（36.92 ± 12.39）with blood glucose monitoring capability the worst. According tostatistical analysis，age，education level，course of diabetes，blood sugar control level，family history of diabetesand self⁃care activities are related factors of QOL. Age，education，course of disease，blood sugar control and self⁃careactivities are the main factors that affect the QOL of the subjects（P＜0.05）. The regression equation modelshows that the older patients with the longer course of disease，worse blood sugar control and weaker self⁃careactivities，received worse QOL score. Area under ROC curve was 0.698（95%CI：0.604 ~ 0.793，P＜0.001），self⁃care activities were an important index to predict QOL. Conclusion The QOL of elderly patients with T2DM andCAAS is generally poor. It is necessary to enhance the self⁃care activities of the patients，especially blood glucosemonitoring care；actively improve the mental and psychological health of the patients；pay attention to the influ⁃ence of risk factors such as age and disease course to improve the QOL of patients.
