Objective:To investigate the current situation of expected sadness of family caregivers of first stroke patients and analyze its influencing factors, so as to provide reference for the formulation of psychological decompression intervention program for family caregivers of stroke patients.Methods:Convenience sampling method was used to conduct cross-sectional survey of 212 family caregivers of first stroke patients who were hospitalized in the First Affiliated Hospital of Shandong First Medical University from March 2020 to May 2021, using general information questionnaires and Anticipatory Grief Scale and Connor-Davidson Resilience Scale to investigate and anlalyzed its influencing factors.Results:The scare of anticipatory grief of the caregivers of first stroke patients was 87.93 ± 17.36. The results of multiple stepwise regression analysis showed that the age of family caregivers, psychological elasticity, the degree of relationship with patients, patients′ cognitive ability and self-care ability were the influencing factors of anticipatory grief of family caregivers of first stroke patients ( t values were -6.73 -11.77, P <0.05).

Objective:To evaluate the efficacy of disposable disinfection cap in preventing catheter-related blood stream infections (CRBSIs).Methods:Literature on the prevention of CRBSIs by disposable disinfection caps were retrieved from CNKI, Wanfang Database, VIP database, Chinese Biomedical Literature Database, PubMed, Cochrane Library, Embase and Web of Science databases. The retrieval period was from the database construction to June 30, 2022. After literature screening, data extraction and quality evaluation were independently carried out by 2 researchers, RevMan5.4 software was used for analysis.Results:A total of 12 articles were included, including 9 832 patients. Meta-analysis results showed that compared with conventional manual disinfection, disposable disinfection cap could reduce the incidence of CRBSIs, and the difference was statistically significant ( RR = 0.58, 95% CI 0.43-0.79, P<0.01). Disposable disinfection cap could reduce the incidence of CRBSIs in adults, but there was no significant difference in the incidence of CRBSIs in children ( P>0.05). It could reduce the incidence of CRBSIs in patients with indwelling vascular catheters in ICU ( RR = 0.58, 95% CI 0.38-0.89, P<0.05), but there was no statistical difference in the incidence of CRBSIs in patients without indwelling vascular catheters in ICU ( P>0.05). In addition, the compliance of the use of disinfection caps by nursing staff was improved by 80% - 90% and the treatment cost was saved by about 282 - 464 dollars. Conclusions:Disposable disinfection caps can reduce the occurrence of CRBSIs, improve the disinfection compliance of nursing staff, and save the hospitalization cost of patients. It is suggested to be popularized in clinical practice.
