Oral anxiolytics prior to routine resident cataract surgery eliminate need for intravenous sedation at a Veterans Affairs Hospital

Abstract

PurposeTo assess the frequency of intraoperative intravenous sedation administration during routine resident-performed cataract surgery among patients receiving pre-operative oral sedation at a Veterans Affairs Medical Center and its impact on patient safety and system cost. MethodsRetrospective review of all resident-performed cataract surgeries performed at the Iowa City Veterans Affairs Medical Center in 2013 and 2017. Cases monitored by a registered nurse were included. Combined cases and cases monitored by an anesthesia provider were excluded. Pre-operative placement of an intravenous (IV) catheter, administration of intra-operative IV sedation, oral diazepam administration, anesthesia type, conditions for administering intraoperative IV medication, and cost of IV catheter placement were recorded. ResultsOf 1025 patient cases included for analysis, 972 received pre-operative diazepam (94.9%) and 1017 (99.3%) had IV catheters placed. One patient received a planned dose of IV methylprednisolone. Zero patients received supplemental intraoperative IV sedation. The estimated materials cost of unused IV catheters was $10,668 over 2 years. ConclusionsPre-operative IV catheter placement may not be necessary in patients undergoing routine resident cataract surgery with pre-operative oral sedation. Discontinuation of routine IV placement may improve patient satisfaction and decrease health care costs without compromising patient safety.
