Intravenous peripheral catheter dwell times: randomised controlled trial of hospital in-patients
Background: There is currently no high grade evidence on which to base decisions about the frequency of intravenous cannula re-sites
Objective: To assess the safety of changing peripheral venous cannulas when clinically indicated
Design: Randomised controlled trial Setting: A tertiary referral hospital in Brisbane, Australia Participants: 206 hospitalised patients from surgical, medical and orthopaedic wards
Interventions: Peripheral intravenous cannulas were re-sited only when complications occurred (intervention group) or every 3 days (control group). Main outcome measures: The primary endpoint was a composite measure of complications leading to an unplanned cannula removal, the secondary outcome was cost. Results: Forty six patients had unplanned removals in the intervention group compared with 41 in the control group [relative risk 1.12, 95% confidence interval 0.81 to 1.55 (p = 0.286)]. Total duration of peripheral cannulation was similar in both groups (mean 123.3 hours in the intervention group and 125.9 hours in the control group: P = 0.82) but significantly more re-sites occurred in the control group (167 in intervention group, 202 in the control group: p = 0.022). Cost of cannula replacements in the intervention group was AUD$3,183.62 and in the control group AUD$3,837.56 (p = 0.006). After adjustment for other risk factors, frequency of cannulation [odds ratio (OR) 0.78. 95% confidence interval (CI) 0.27 – 0.22], total duration of cannulation (OR 1.01. CI 1.00 – 1.02) and irritability of IV medications other than antibiotics (OR 0.45, CI 0.21 – 0.97) were positively associated with unplanned cannula removal.
Conclusion: Re-siting peripheral venous cannulas when clinically indicated compared with changing them routinely every 3 days does not lead to more complications and reduces costs.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
