Background: While oral laxatives represent the first-line treatment of fecal impaction, enemas are frequently used in clinical practice in pediatric emergency departments (PEDs) and by family pediatricians (FPs). Objectives: Phosphate-containing enemas (PcEs) are commonly employed, even causing the risk of rare but lethal toxicity. We investigated pediatricians’ awareness of PcE risks. Methods: We conducted an online survey by sending a multiple-choice questionnaire to the referents of 51 PEDs and 101 FPs. We collected and compared the answers with recommendations reported by the Italian Drug Agency (AIFA) and the available literature about PcE administration. Results: Of the institutions and pediatricians receiving the questionnaire, 23 PEDs (45%) and 63 FP (62.3%) participated in the survey. Of PEDs, 95% and 33.0% of FPs treated fecal impaction with PcE. Moreover, 54% of PEDs and 86.0% of FPs did not provide treatment according to the AIFA recommendations for the daily dose. Conclusions: This study shows limited pediatricians’ awareness of the potential risks related to PcE.
