Under-Reporting of a Critical Perioperative Adverse Event: Intravenous Infiltration and Extravasation.

A critical step in understanding and preventing potentially disastrous complications in the perioperative period is the accurate recording of their occurrence and subsequent analysis. However, the recording of intravenous infiltration and extravasation is likely inaccurate due to several factors: rare serious complications associated with infiltration/extravasation, limitation in ICD-10 codes to describe the injury, reliance on coders to record these events in searchable databases, and limited quality measures in anesthesiology to record these events. Although current literature cites results of studies that found rates of 16% and higher for intravenous infiltration, a limited internal review at University Hospital in Newark, NJ found significantly lower rates with only 14 instances recorded in an 18-month period across the institution. This leads the author to conclude that interventions are required to better track these events including such steps as staff education and more efficient/accessible reporting systems. The accurate recording and analyzing of data related to adverse events, and in particular regarding infiltration and extravasation, require revision and reinterpretation to gain an accurate picture of their rates.
