Analysis of the Prevalence and Influencing Factors of Chronic Obstructive Pulmonary Disease in Elderly Hospitalized Patients：a Study Based on a Comprehensive Geriatric Assessment System in Yunnan Province

Abstract

BackgroundCurrent studies on chronic obstructive pulmonary disease (hereinafter referred to as COPD) mostly focus on the lung itself, while studies on the extrapulmonary manifestations of COPD are still lacking. Many studies in China and at abroad have shown that COPD is closely related to geriatric syndrome, but it has not been further confirmed.ObjectiveTo investigate the prevalence of COPD in senile inpatients in several hospitals in Yunnan Province in the past three years, and to explore the influencing factors of elderly COPD from the aspect of geriatric syndrome.MethodsA total of 2 182 newly admitted elderly patients (≥60 years old) in several hospitals of Yunnan Province from September 2018 to June 2021 were selected as the research objects and divided into COPD group and non-COPD group according to whether the patients had COPD. The software platform of "Comprehensive Geriatric Assessment System" independently developed by the Geriatrics Department of the First People's Hospital of Yunnan Province was used to collect general data from the patients. At the same time, the scales in the system were used to conduct a comprehensive geriatric evaluation of the patients, including the assessment of anxiety and depression by 15-item geriatric depression scale (GDS-15) , the assessment of insomnia situation by athens insomnia scale (AIS) , the assessment of family support by PAGAR scale, the assessment of fall risk by Morse fall scale, the assessment of cognitive function by mini-mental state examination (MMSE) , the assessment of nutrition status by mini nutritional assessment scale, the assessment of the patients' daily living ability by the basic activities of daily living (BADL) scale, the assessment of frailty state by the Fried Scale, the assessment of swallowing (choking) by swallowing function assessment scale, the assessment of urinary incontinence by incontinence questionnaire simple form (ICI-Q-SF) , the assessment of constipation by Roma Ⅲ scale, the assessment of pain by visual analogue scale (VAS) . The influencing factors of COPD in the elderly hospitalized patients were analyzed by binary Logistic regression.ResultsThere were 1 558 cases (71.4%) in the non-COPD group and 624 cases (28.6%) in the COPD group. The results of binary Logistic regression analysis showed that age ≥75 and <85 years, age≥85 years old, male, anxiety and depression, potential malnutrition, malnutrition, pre-frailty, frailty were independent influencing factors of COPD (P<0.05) .ConclusionElderly hospitalized patients aged ≥60 years have a higher prevalence of COPD and are closely associated with geriatric syndrome.
