Objective To systematically review the incidence of peripherally inserted central catheter（PICC）-related thrombosis in Chinese adult cancer patients. Methods PubMed,Embase,the Cochrane Library,Web of Science,CBM,CNKI,WanFang Data and VIP databases were electronically searched to collect studies on the incidence of PICC-related thrombosis in Chinese adult cancer patients from inception to May,2021. 2 reviewers independently screened the literature,extracted the data and assessed the risk of bias of included studies,and then the meta-analysis was performed by Stata 14.0 software. Results A total of 23 pieces of the literature involving 15 066 cancer patients were included. Meta-analysis results showed that the total incidence of PICC-related thrombosis in Chinese adult cancer patients was 8.82%[95%CI（5.93%~12.18%）]. Subgroup analysis showed that the incidence of PICC-related thrombosis was higher in the publication year from 2019 to 2021. The incidence was also higher in patients with age≥ 60 years old,BMI>25,cephalic vein puncture,traditional puncture method,the number of punctures more than 1,catheter size of 5 Fr,lung cancer,cancer stage of Ⅲ~Ⅳ,diabetes mellitus,history of PICC catheterization,history of venous thrombosis,fibrinogen content≥4 g/L before catheterization and D-dimer level≥0.5 mg/L before catheterization. Conclusions The incidence of PICC-related thrombosis in Chinese adult cancer patients is high,so health workers should pay more attention to early screening and prevention of high-risk patients.

Objective To construct the evaluation index system of health management needs for home-based care of the disabled elderly under the background of combination of medical and health care,in order to scientifically and systematically assess the health needs of the elderly disabled,promote and improve the health support system for the disabled elderly. Methods Through literature review,semi-structured interviews and Delphi method,the index system for assessing the health management needs of the disabled elderly was established. Results The effective recovery rates of 2 rounds of expert consultation were 100% and 94.44% respectively. The expert opinions tended to be consistent. Finally,the index system of the health management needs assessment for home-based care of disabled elderly with 4 first-level indicators,9 second-level indicators and 36 third-level indicators was formed. Conclusion The constructed index system of health assessment needs for the disabled elderly is scientific,reasonable,practical and content-oriented,which can provide references for the formulation of the health service system for the disabled elderly.
