Background/Aims: Percutaneous endoscopic gastrostomy (PEG) tube placement is a common procedure used to initiate enteral feeding. To our knowledge, there are no previous studies that analyze predictors of PEG failure. This study aims to identify risk factors forfailure of inpatient PEG placement. Methods: A retrospective chart review was conducted of inpatients in the Montefiore Health System who were scheduled to undergoPEG placement from 2016 to 2020 (n=1,138). Patient, endoscopist, and procedural characteristics were summarized using descriptivestatistics, both overall and stratified by whether the PEG was successfully placed. Results: The overall success rate of PEG placement was 89%. The most common indications included stroke (31%), dementia (27%),and ventilator use (24%). Patient characteristics, including body mass index (BMI) (p=0.16) and indication for PEG placement(p=0.06), were not significantly associated with PEG failure. Instead, endoscopist and procedural characteristics were found to be significant,including type of attending (p<0.001), location of case (p=0.02), and category of anesthesia (p<0.001). Conclusions: PEG placement remains a highly successful procedure. Endoscopist and procedural characteristics, not patient characteristics,were associated with PEG placement success. Notably, patient BMI and indication for PEG placement could not be used torisk stratify candidates for PEG placement.
