Investigation and epidemiological analysis of chronic diseases and comorbidities in hospitalized patients
Abstract
Objective·To investigate the current situation and distribution characteristics of chronic comorbidities, and to provide reference for further improving the self-management of comorbidities and implementing the whole course and all-round management of comorbidity.Methods·Two thousand and forty-five inpatients in the Department of Geriatrics,Renji Hospital, Shanghai Jiao Tong University School of Medicine were enrolled in this study from December 2020 to February 2023. The general vital signs, routine laboratory examination and disease status were collected. The epidemiological distribution characteristics of chronic diseases and comorbidities were analyzed.Results·The incidence of chronic diseases in the surveyed population was 99.6%, and the incidence of comorbidities was 94.2%. The top 5 chronic diseases were hypertension (43.68%), diabetes mellitus (24.81%), malignant tumor (21.48%), hyperlipidemia (18.38%) and coronary heart disease (11.99%). The detection rates of hypertension, diabetes mellitus, coronary heart disease, chronic obstructive pulmonary disease, stoke and chronic kidney disease in males were significantly higher than those in females (P<0.05). The proportion of patients with 5 chronic diseases was the highest (11.99%), followed by 7 chronic diseases (10.26%) and 6 chronic diseases (10.04%). Among the patients of different ages, the comorbidity rate was the highest in the patients aged 50‒59 years (27.78%). In different age groups, patients aged 50 to 59 with 2 chronic diseases had the highest incidence of comorbidity, which was as high as 40.82%. Although the overall proportion of comorbidities among male patients (95.37%) was higher than that among females (93.77%), there was no statistically significant difference (P=0.125). However, the proportions of male patients with 2 and 5 chronic diseases were 70.41% and 60.63%, respectively, which were significantly higher than those of female patients (29.59% and 39.37%). The correlations between coronary heart disease and diabetes mellitus, hypertension and coronary heart disease, hypertension and diabetes mellitus were higher (r=0.24, r=0.27, r=0.35, all P<0.05).Conclusion·The prevalence of chronic diseases and comorbidities is high in the middle-aged and elderly population, and the number of comorbidities increases significantly with the increase of age.
