Aim Children and their families have reported peripheral intravenous catheter (PIVC) insertion as the most stressful part of their emergency department (ED) encounter, with some enduring multiple attempts without a successful insertion. The purpose of this study was to identify factors associated with abandonment of paediatric PIVC insertion.

Methods A retrospective cohort study was conducted at the Gold Coast University Hospital. All patients 16 years of age and younger, presented in 2019 with a PIVC insertion attempted in the ED were eligible. The electronic medical records were screened by two reviewers to identify those who required a PIVC insertion. Logistic regression analysis was performed to assess variables associated with PIVC insertion abandonment.

Results Of 6394 records screened, 2401 (8.3%) had a PIVC insertion attempted, with 99 (4.1%) being abandoned. Age <12 months was the strongest predictor of PIVC abandonment at a rate of 11.3% (38/336), with a >10-fold increased risk for infants less than 3 months old and 3–12 months old; adjusted odds ratio (95% confidence interval) 12.4 (5.1–30.2) and 14.8 (5.8–37.4), respectively. Indications of ‘infection’ or ‘rehydration’ were associated with a decreased likelihood of abandonment when compared to ‘investigation only’ in multivariate modelling (odds ratio (95% confidence interval): 0.181 (0.099–0.332) and 0.262 (0.100–0.686), respectively).

Conclusions This study suggests the rate of PIVC insertion abandonment in children is relatively infrequent. However, more than one in 10 children aged <12 months had PIVC attempts without successful insertion. PIVC abandonment was less likely when there was an indication that necessitated PIVC insertion, such as a serious bacterial infection.
