Objective:To explore home maintenance acceptance of family members of elderly discharged patients with peripherally inserted central catheter (PICC) catheter and to analyze its influencing factors.Methods:From January to November 2019, a total of 143 family members of elderly patients who were given PICC in three ClassⅢ Grade A hospitals in Wenzhou and discharged with catheter were selected as research objects. A questionnaire survey was conducted on 143 family members of elderly discharged patients with PICC catheter using a general information questionnaire, Catheter Maintenance Related Cognitive Questionnaire and Barthel Index Rating Scale (BI) . A total of 143 questionnaires were distributed in this study and a total of 143 valid questionnaires were recovered. The effective recovery rate was 100%.Results:The acceptance rate of home maintenance of 143 family members of elderly discharged patients with PICC catheter was 60.14% (86/143) . Single factor analysis showed that home maintenance acceptance score of family members of elderly discharged patients with PICC catheter had statistically significant differences in working status of family members, ADL score of patients, whether they stayed in bed, whether the catheter maintenance in the residence was convenient, whether they were confident in catheter observation and treatment and whether they were worried about the effect of home maintenance ( P<0.05) . Multivariate logistic regression analysis showed that the convenience of catheter maintenance in the residence, self-care ability of patients and whether they were worried about the maintenance effect were the influencing factors of the home maintenance acceptance of family members of elderly discharged patients with PICC catheter ( P<0.05) . Conclusions:The family maintenance acceptance of elderly discharged patients with PICC catheter is at a medium level. It is necessary to strengthen the maintenance knowledge education and operation skills training of family members with inconvenient catheter maintenance in residence and poor self-care ability of patients and help them to improve the maintenance effect so as to better carry out home maintenance.

Objective To investigate the prevalence of nutritional risk,undernutrition and nutritional support among elderly inpatients with coronary heart disease in 11 tertiary A hospitals in China.Methods Records of elderly patients under the age of 90 with coronary heart disease were collected between March 2012 and May 2012 from 11 tertiary A hospitals in China following the direction of diagnosis related group of Beijing government.Results A total of 1 279 consecutive cases were recruited with the average age 74 years old (65-89).The total nutritional risk prevalence was 28.14％ (360/1 279).The prevalence of nutritional risk and nutritional risk score ≥ 5 increased with age.The prevalence of nutritional risk (12.88％ vs.30.08％ vs.42.28％) and nutritional risk scored ≥5 (10.86％ vs.18.61％ vs.27.78％)increased with age.Judging from BMI,most patients were overweight or obese (BMI ≥ 24 kg/m2),accounting for 53.0％ of the total,and prevalence of nutritional risk in this subgroup was 15.12％ (96/635).The prevalence of nutritional risk in patients with normal BMI was 34.24％.The prevalence of undernutrition defined as BMI＜ 18.5 kg/m2 was 4.25％ (51/1 279),among which patients with score ≥ 5 account for 64.7％ (33/51).The prevalence of undernutrition defined as nutritional impairment score =3 was 7.58％ (97/1 279).In patients with nutritional risk,57 were administrated nutrition support (16.6％);in patients without nutritional risk,21 received nutrition support,mostly parenteral nutrition (16 cases,76.2％).In patients with nutritional risk [(79.46± 7.19) years vs.(76.40± 6.16) years],there were statistically significant difference between those who received nutrition support and those who did not in terms of age and the ratio of patients with nutritional risk scored≥5 (35.1％ vs.17.1％) (P =0.001,P=0.002).Conclusions The prevalence of nutritional risk in patients with coronary heart disease was high.The prevalence of undernutrition was low.Prevalence of overweight and obese was high,but there was still nutritional risk in this group of patients.The patients who received nutrition support were older and had high nutritional impairment score,but the indication is not rationale.

Objective:To evaluate nutritional status and to analyse risk factors of acute exacerbation of chronic obstructive pulmonary disease (COPD) in the elderly.Methods:Data of elderly hospitalized patients with COPD mainly from 5 grade A, class 3 hospitals (Beijing Hospital, Shanghai Huadong Hospital, Tianjin Nankai hospital, the Second Affiliated Hospital of Medical College of Zhejiang University, Guangzhou First People′s Hospital) from January 2012 to December 2020 were retrospectively analyzed. According to the global initiative for chronic obstructive lung disease criteria (GOLD), elderly COPD patients were divided into acute exacerbation group and stable group. The differences in age, gender, medical history, anthropometry, laboratory examination, nutritional support, results of nutritional risk screening 2002 (NRS2002) and global leadership initiative on malnutrition (GLIM) were compared between the two groups after admission, and the risk factors of acute exacerbation of COPD in the elderly were analyzed by multivariate Logistic regression.Results:A total of 339 elderly patients with COPD aged 65-100 years were included in this study, including 177 cases (52.21%) in acute exacerbation stage. The detection rate of malnutrition in acute exacerbation stage was higher than that in stable stage (51.98% vs 41.98%, P<0.05). The weight, body mass index and grip strength of patients in the acute exacerbation stage were significantly lower than those in the stable period [(55.47±8.42) vs (60.63±9.30) kg, (20.52±4.25) vs (22.39±4.57) kg/m 2, (12.32±4.21) vs (16.59±2.97) kg] (all P<0.05). Spearman correlation analysis showed that the acute exacerbation of elderly patients with COPD was positively correlated with malnutrition ( r=0.443, P<0.001), and negatively correlated with body weight, body mass index and calf circumference ( r=-0.200, -0.214, -0.135, all P<0.05). Multiple Logistic regression analysis showed that acute exacerbation in elderly patients with COPD was only related to malnutrition ( OR=7.799, 95% CI: 4.466-13.622, P<0.001). Conclusions:The incidence of malnutrition in acute exacerbation stage of elderly COPD patients is high. Malnutrition is independently related to acute exacerbation of COPD.
