, according to a new large population-based study.
In June 2023, the American Society of Anesthesiologists (ASA) recommended holding GLP-1 RAs before an endoscopic or surgical procedure to reduce the risk for complications associated with anesthesia and delayed stomach emptying.
In response, the American Gastroenterological Association (AGA) published a rapid clinical practice update in November 2023 that found insufficient evidence to support patients stopping the medications before endoscopic procedures.
“It is known that GLP-1 RAs significantly reduce the motility of the stomach and small bowel. As more and more patients are being started on GLP-1 RAs at higher doses and longer half-life, the question became whether the current recommended fasting durations are enough to reasonably assume the stomach is empty prior to procedures that require sedation,” said senior author Ali Rezaie, MD, medical director of the GI Motility Program at Cedars-Sinai Medical Center in Los Angeles.
“We wanted to see if these medications in fact increased the chance of aspiration before the ASA suggestion went into effect,” he said. “However, this is not an easy task, as aspiration is a rare event and a large sample size is needed to confidently answer that question. That is why we evaluated nearly 1 million cases.”
The study was published online in Gastroenterology.
Analyzing GLP-1 RA Use
Dr. Rezaie and colleagues conducted a population-based, retrospective cohort study of the TriNetX dataset, which includes 114 million deidentified individual health records from 80 healthcare organizations. The research team analyzed nearly 1 million records for adult patients between ages 21 and 70 who underwent upper and lower endoscopies between January 2018 and December 2020.
The researchers defined GLP-1 RA users as those who had the medication for more than 6 months and two or more refills within 6 months before the procedure. They adjusted for 59 factors that could affect gut motility or aspiration risks, such as obesity, numerous chronic diseases, and dozens of medications. The primary outcome was aspiration pneumonia within a month after the procedure.
Among 963,184 patients who underwent endoscopy, 46,935 (4.9%) were considered GLP-1 RA users. Among those, 20,099 GLP-1 RA users met the inclusion criteria and had their results compared with non-GLP-1 RA users.
After propensity score matching for the 59 potential confounders, GLP-1 RA use had a higher incidence rate of aspiration pneumonia (0.83% vs 0.63%) and was associated with a significantly higher risk for aspiration pneumonia, with a hazard ratio (HR) of 1.33.
An even higher risk was seen among patients with propofol-assisted endoscopies (HR, 1.49) but not among those without propofol (HR, 1.31).
In a subgroup analysis based on endoscopy type, an elevated risk was observed among patients who underwent upper endoscopy (HR, 1.82) and combined upper and lower endoscopy (HR, 2.26) but not lower endoscopy (HR, 0.56).
“The results were not necessarily surprising given the mechanism of action of GLP-1 RAs. However, for the first time, this was shown with a clinically relevant outcome, such as aspiration pneumonia,” Dr. Rezaie said. “Aspiration during sedation can have devastating consequences, and the 0.2% difference in risk of aspiration can have a significant effect on healthcare as well.”
More than 20 million endoscopies are performed across the United States annually. Based on the assumption that about 3% of those patients are taking GLP-1 RAs, about 1200 aspiration cases per year can be prevented by raising awareness, he said.
Considering Next Steps
The varying risk profiles observed with separate sedation and endoscopy types point to a need for more tailored guidance in managing GLP-1 RA use before a procedure, the study authors wrote.
Although holding the medications before endoscopy may disrupt diabetes management, the potential increased risk for aspiration could justify a change in practice, particularly for upper endoscopy and propofol-associated procedures, they added.
At the same time, additional studies are needed to understand the optimal drug withholding windows before endoscopies and other procedures, they concluded.
“We will need more data on what is the optimal duration of holding GLP-1 RAs,” Dr. Rezaie said. “But given our data and current ASA guidance, stopping these medications prior to elective procedures is the safe thing to do.”
For now, AGA guidance remains the same as offered in the November 2023 update, suggesting an individual approach for each patient on a GLP-1 RA rather than a “blanket statement” on how to manage all patients taking these medications.
“Overall, I believe that this study is important, but we require more high-level data to inform clinical decision-making regarding patients using GLP-1 receptor agonists prior to gastrointestinal endoscopy,” said Andrew Y. Wang, MD, AGAF, chief of gastroenterology and hepatology and director of interventional endoscopy at the University of Virginia in Charlottesville.
Dr. Wang, who wasn’t involved with this study, coauthored the AGA rapid clinical practice update. He and colleagues advised continuing with a procedure as planned for patients on GLP-1 RAs who followed standard preprocedure fasting instructions and didn’t have nausea, vomiting, dyspepsia, or abdominal distention.
Among patients with symptoms that suggest retained gastric contents, rapid sequence intubation may be considered, though it may not be possible in ambulatory or office-based endoscopy settings, Dr. Wang and colleagues wrote. As another option in lieu of stopping GLP-1 RAs, patients can be placed on a liquid diet for 1 day before the procedure.
“While this study found a signal suggesting that patients using GLP-1 RAs had an increased risk of aspiration pneumonia within 1 month following upper endoscopy or combined upper and lower endoscopy, it does not inform us if having patients stop GLP-1 RAs before endoscopic procedures — especially for a single dose — will mitigate this potential risk,” Dr. Wang said.
“It was also interesting that these investigators found that patients taking GLP-1 RAs who underwent lower endoscopy alone were not at increased risk for aspiration pneumonia,” Dr. Wang noted.
The authors didn’t report a funding source and disclosed no potential conflicts. Dr. Wang reported no relevant disclosures.
