The high incidence of bleeding after peripherally inserted central catheter (PICC) catheterization increases the risk of puncture site infection and unplanned extubation. Hemostatic dressings should be used in the early stages of catheterization to reduce blood infiltration. However, new hemostatic dressings have various types and advantages, which makes them difficult to choose dressings for medical staff. This paper introduces the types and hemostatic characteristics of novel functional hemostatic dressings, reviews the hemostatic mechanism and hemostatic effect of chitosan, cyanoacrylate gum, alginate, gelatin sponge and oxycellulose dressings in PICC puncture respectively, and prospects the development of new functional hemostatic dressings. It is expected that future hemostatic dressings will move towards multifunctionality and compositeness.

With the increasing aging process, the number of elderly people with cognitive frailty is gradually increasing, which has a profound impact on the clinical outcomes of the elderly. Early identification and precise intervention of cognitive frailty can delay the occurrence of adverse outcomes. This paper reviews the development and research status of cognitive frailty risk prediction models for the elderly in the community, summarizes and compares the characteristics and basic situation of each prediction model, in order to provide references for improving the early identification and intervention of cognitive frailty among the elderly population in the community.

Objective:To explore the current situation of stigma among disabled elderly inpatients and analyze its influencing factors, so as to provide reference for formulating targeted intervention measures.Methods:This study was a cross-sectional survey. In December 2023, convenience sampling was used to select 428 disabled elderly inpatients from 12 ClassⅢ Grade A hospitals in Sichuan Province as research subjects. General Information Questionnaire and Social Impact Scale (SIS) were used to conduct surveys on patients. Multiple linear regression analysis was used to explore the influencing factors of stigma among disabled elderly inpatients.Results:A total of 428 questionnaires were distributed, and 407 valid questionnaires were collected, with a valid response rate of 95.09% (407/428). SIS score of 407 disabled elderly inpatients was (56.55±8.38). Multiple linear regression analysis showed that the number of diseases, educational level, and self-rating economic pressure were the influencing factors of stigma among disabled elderly inpatients ( P<0.05) . Conclusions:The stigma among disabled elderly inpatients is at a moderate level. Medical and nursing staff should establish a comprehensive prevention and management mechanism based on influencing factors.

Objective:To investigate the current situation of the fatalism of the disabled elderly in hospital, and to analyze the influencing factors, so as to provide a basis for the later development of targeted intervention programs.Methods:This was a cross-sectional survey study. From December 2 to 29, 2023, the convenience sampling method was used to investigate the disabled elderly hospitalized in 7 tertiary general hospitals in Sichuan Province by the general information questionnaire, the Activity of Daily Living scale and the Fatalism Scale. And its influencing factors were conducted by the multivariate linear regression.Results:A total of 280 questionnaires were distributed in this survey, and 269 questionnaires were effectively recovered, with an effective recovery rate of 96.07%(269/280). There were 136 males and 133 females, aged 60-69 years old with 61 cases, 70-79 years old with 103 cases, ≥80 years old with 105 cases. The score of the fatalism in hospitalized disabled elderly was (48.87 ± 10.02) points, of which the pre-determined dimension score was (18.73 ± 4.17) points, the luck dimension score was (12.75 ± 3.42) points, and the pessimistic dimension score was (17.39 ± 4.72) points. Multivariate linear regression showed that the frequency of visits to relatives and friends and the level of education were protective factors for the occurrence of fatalism (t=-3.02, -2.81, both P<0.05), and economic pressure was a risk factor for the occurrence of fatalism (t=4.35, P<0.01).Conclusions:The fatalistic view of the disabled elderly in the hospital is at a medium level.Medical staff can start from the influencing factors, formulate relevant intervention measures, and improve the level of the patient's fatalism.

To explore the effect of doctor-patient relationship perception on work performance among medical staff in public hospitals and its mechanism. The convenient sampling method was used to select 380 medical staff working in four public tertiary hospitals in Sichuan Province, Zhejiang Province, and Fujian Province from August 2022 to October 2022 as the research objects, and the General Information Questionnaire, Doctor-Patient Relationship Scale, General Self-Efficacy Scale, Perceived Organizational Support Scale, Work Performance Questionnaire were used. This paper showed that the doctor-patient relationship perception of medical staff was negatively correlated with self-efficacy (r=-0.392, P<0.01) and work performance (r=-0.286, P<0.01), self-efficacy was positively correlated with perceived organizational support (r=0.538, P<0.01) and work performance (r=0.507, P<0.01), perceived organizational support was positively correlated with work performance (r=0.510, P<0.01). Self-efficacy played a partial mediating role between doctor-patient relationship perception and work performance, and its effect value was -0.241, accounting for 64.78% of the total effect. Perceived organizational support weakened the negative predictive effect of doctor-patient relationship perception on self-efficacy, which moderates the first half path of the mediating model that doctor-patient relationship perception affects work performance through self-efficacy. It indicated that the doctor-patient relationship perceived by medical staff in public hospitals is poor. Measures should be taken from the aspects of policy support, hospital and society levels to alleviate the doctor-patient relationship, play the mediating role of self-efficacy and the moderating role of organizational support, minimize the negative impact of doctor-patient relationship on the work performance among medical staff, and improve the work performance of medical staff, so as to improve the overall quality of medical services.
