Scoping review on prevention of central venous catheter-related bloodstream infection in burn patients

Abstract

Objective: To investigate the research trend and scope of prevention of central venous catheter-related bloodstream infection (CRBSI) in burn patients. Methods: The scoping review method was adopted. Pre-retrieval was carried out with search terms of ", , " and "central venous catheter, infection, catheter-related bloodstream infection, burn". On the basis of pre-retrieval, different retrieval formulas were formulated to retrieve researches related to central venous CRBSI in burn patients in China National Knowledge Internet, Wanfang Database, VIP Database, PubMed, Embase, CINAHL, and Cochrane Library from the establishment of each database to August 2020. Data were extracted from the included literature, including the first author, research publication time, research country, research type, diagnosis basis and intervention measures of central venous CRBSI, research sample selection, incidence related to infection, and research conclusion. Results: A total of 20 randomized controlled trials, quasi-experimental studies, case-control studies, cohort studies, and implementation researches published in 1990-2020 were included in this study with the first authors from China, the United States of America, or Argentina. The diagnostic bases for central venous CRBSI in burn patients were not uniform in the included literature, including adopting the Guidelines of American Centers for Disease Control and Prevention, Diagnostic Criteria for Nosocomial Infection, and other diagnostic criteria without specifying the source. The intervention measures included the use of new materials such as antibiotics coated catheter and ethanol impregnated port protectors, multidisciplinary cooperation, and comprehensive preventive measures. The sample size in the included literature was small, and the sample selection was different, including the number of patients and the the number of placement of central venous catheter. The outcome indicators for infection in the included literature were diversified. The incidence per 1 000 days of central venous CRBSI was 20.41‰-29.1‰ of patients in control group in China, the incidence per 1 000 days of central venous CRBSI was mostly <16.6‰ in control group in foreign countries, and the incidence of central venous CRBSI was decreased to varying degrees after implementing the corresponding intervention measures. Related research conclusions showed that new materials, multidisciplinary cooperation, and comprehensive preventive measures had good effects on prevention of central venous CRBSI in burn patients. Conclusions: The researches on prevention of central venous CRBSI in burn patients in China start early and the research types are diversified. The diagnostic criteria of central venous CRBSI in burn patients are not uniform, intervention measures have shifted from standardizing relevant operational measures to exploring the prevention effects of new materials, multidisciplinary cooperation, and multiple measures, and the latter has good effects on preventing central venous CRBSI in burn patients.
