Design and application effect of intravenous indwelling catheter occlusion risk warning and pre-control scheme

Abstract

Objective To study and design an early warning and pre-control scheme for the risk of intravenous catheter blockage and observe the application effect in the clinical practice. Methods This study was divided into three stages: the first stage established the risk early warning plan of intravenous indwelling catheter occlusion through literature review, expert consultation, analytic hierarchy process and retrospective research; the second stage summarized the best evidence of intravenous indwelling catheter occlusion intervention through literature retrieval and literature quality evaluation, and established the risk through expert consultation. In the third stage, by convenience sampling we selected the inpatients from some departments of a Class Ⅲ Grade A hospital in Jilin Province to carry out non-synchronous control experiment. A total of 236 inpatients who used intravenous indwelling catheter from May to June of 2018 were taken as the observation group, and 218 inpatients from May to June of 2017 were taken as the control group. The occurrence of intravenous indwelling catheter occlusion and indwelling time of intravenous indwelling catheter were compared between the two groups. Results A pre-warning evaluation scheme consisting of two first-level indicators, eight second-level indicators and 17 third-level indicators was formed, and three early-warning levels, low-risk, medium-risk and high-risk, were determined. A pre-control scheme was formed for different early-warning levels. The non-synchronous control experiment showed that the incidence of intravenous indwelling catheter occlusion in the observation group was higher than that in the control group, the difference between the two groups was statistically significant (P<0.05) ; the indwelling time of intravenous indwelling catheter in the observation group was longer than that in the control group, and the difference between the two groups was statistically significant (P<0.05) . Conclusions The use of risk early warning theory, the forming of a comprehensive risk factor assessment program, and the use of forward-looking nursing thinking in the implementation of targeted pre-control program, can help to improve nurses' ability to identify and control the risk of intravenous indwelling catheter occlusion, reduce the incidence of indwelling catheter occlusion, and effectively prolong the indwelling time.
