The impact of the difficult vascular access, fear, and anxiety level in children on the success of first-time phlebotomy

Abstract

Purpose: This study aimed to investigate the success of first-time phlebotomy and the affecting factors in children between 4 and 10 years of age. Methods: This descriptive, comparative, and cross-sectional study was conducted on 155 children who underwent phlebotomy. The Sociodemographic Data Form, the Children’s Anxiety Meter–State, the Children’s Fear Scale, and the Difficult Intravenous Access score were used to collect the data for the study. The relationship between the success of first-time phlebotomy, mean pre-phlebotomy fear and anxiety score, and Difficult Intravenous Access score were examined. The variables affecting the success of first-time phlebotomy were assessed by regression analysis. Results: Phlebotomies failed in 18.1% of children. A statistically significant relationship was found between the success of first-time phlebotomy, Children’s Anxiety Meter–State, Children’s Fear Scale mean scores assessed by the researchers, and Difficult Intravenous Access score. Factors affecting the success of first-time phlebotomy include difficult vascular access, age, mean Children’s Anxiety Meter–State score, mean Difficult Intravenous Access score, and duration of the last phlebotomy performed. These factors explain 42% of the total factors affecting the success of first-time phlebotomy. Conclusion: Child’s fear, anxiety before phlebotomy, and difficult vascular access affects the first-time phlebotomy success.
