Development and validation of a vein assessment tool (VAT)
Webster, Joan, Morris, Helen-Louise, Robinson, Katherine, & Sanderson, Ursula (2007) Development and validation of a vein assessment tool (VAT). Australian Journal of Advanced Nursing, 24(4), pp. 5-7.
Objective: To assess the face validity and the inter-rater reliability of the Vein Assessment Tool (VAT) for classifying veins according to their level of intravenous insertion difficulty.
Design: Prospective observational study.
Participants: Eight Nurses and two radiographers from the Medical Imaging Department and five nurses from the Haematology Day Patient Unit of a large tertiary hospital.
Intervention: Assessments of veins in the upper limb were undertaken independently by nurses from two departments of a major tertiary hospital.
Main outcome measure: Level of inter-rater agreement, assessed using intraclass correlation coefficients (ICC).
Results: A total of 125 independent assessments were made by 15 nurses. The mean percentage agreement between raters from Medical Imaging was 84% (SD 10.7; range 60% to 100%) and between raters from Oncology was 92% (SD 17.9; range 60% to 100%). The inter-rater reliability was very high for the ten medical imaging raters 0.83 [95% confidence interval (CI) = 0.61–0.95] and for the Oncology raters 0.93 [95% CI = 0.77–0.99].
Conclusion. The Vein Assessment Tool (VAT) has been validated by a sample of nurses with cannulating experience. Following broader testing it may be useful for research studies or by nurses who wish to objectively describe the condition of a vein for clinical purposes.
Citation countsare sourced monthly fromand 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 downloadsdisplays 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.
