Conditions

GLP1-R-related Disease, Upper Endoscopy

Keywords

GLP1 receptor agonists, upper endoscopy

Brief summary

The aim of this study is to determine whether a modified fasting protocol can reduce the potential risk of aspiration for patients currently prescribed GLP1-RAs.

Detailed description

The overall objective of this project is to identify a reasonable means by which patients on GLP1-RAs can be safely cared for in the perioperative period that can be agreed upon by all groups involved in perioperative patient care. This will be assessed in patients undergoing upper endoscopy specifically since assessment of gastric contents would be minimally invasive for this patient population receiving anesthetic care.

Interventions

OTHERModified Fasting Guidelines

Patients will follow a full-liquid diet 48 hours prior to their procedure, clear liquid diet 24 hours prior to their procedure, and nothing by mouth (NPO) after midnight on the day of their procedure

Intervention model description

This study has 3 arms, but two of them are historical cohorts (i.e. previous patients who have already been taken care of). One group will consist of patients who are not on GLP1 medications who underwent upper endoscopy, and another group will consist of patients who are on GLP1 medications who underwent upper endoscopy. The third group is the prospective group who are being enrolled and recruited - this group will consist of patients who are on GLP1 medications who abide by a modified fasting guideline consisting of a full-liquid diet 48 hours prior to procedure, clear liquid diet 24 hours prior to procedure, and no liquids or solids after midnight on the day of upper endoscopy.

Design outcomes

Primary

MeasureTime frameDescription
Gastric contentsBaselineNumber of patients who were found to have gastric contents within the stomach during the upper endoscopy.

Secondary

MeasureTime frameDescription
Diagnosis of aspiration within 72 hours of procedureFrom the time of upper endoscopy until 72 hours post-procedure.Whether or not a patient was diagnosed with aspiration will be determined via chart review for 72 hours after the completion of upper endoscopy. A note documenting aspiration or an ICD code associated with aspiration will indicate that this outcome occurred.
Aspiration pneumonitis diagnosis postoperatively72 hours after completion of upper endoscopyThe number of patients who have a diagnosis of aspiration pneumonitis, as identified by the presence of ICD codes J69.0 or J69.8, postoperatively.
Postprocedural ICU admissionImmediately after upper endoscopyThe number of patients who were admitted to the ICU immediately after upper endoscopy.
