From a population health perspective, that is unquestionably good news.
As GLP-1 utilization continues to accelerate, anesthesia providers, surgical facilities and healthcare organizations are facing a new perioperative challenge—not the medications themselves, but the operational complexities they introduce into patient assessment, scheduling and operating room (OR) efficiency.
A New Variable in Preoperative Planning
Clinical observations have demonstrated that GLP-1 medications may delay gastric emptying in some patients, potentially increasing the risk of retained stomach contents during anesthesia. This creates concerns regarding regurgitation and pulmonary aspiration during general anesthesia and deep sedation.
As a result, anesthesia teams now routinely incorporate additional screening questions into the preoperative evaluation:
- Is the patient taking a GLP-1 medication?
- Which medication and dosage?
- When was the last dose taken?
- Is the patient experiencing gastrointestinal symptoms?
- Does the patient meet current recommendations to safely proceed with surgery?
These questions are essential for patient safety, but they also add complexity to an already demanding perioperative workflow.
The Real Challenge: Late Identification
Most patients taking GLP-1 medications undergo surgery safely without incident. The larger challenge arises when critical information is discovered too late.
When medication use is not disclosed during pre-admission testing, when instructions are misunderstood or when significant gastrointestinal symptoms are identified on the day of surgery, anesthesia providers may be forced to reassess risk in real time.
Some cases proceed with additional precautions. Others require delays or rescheduling. While such decisions are appropriate and patient-centered, they can have a substantial operational impact. A same-day cancellation affects far more than one patient. It disrupts surgeon schedules, leaves OR time unused, creates staffing inefficiencies and reduces procedural throughput.
Understanding Capacity Leakage
Healthcare leaders often focus on the financial impact of cancellations. Equally important is the concept of capacity leakage. This occurs when operating room time, anesthesia staffing and clinical resources have been reserved and are available, yet the scheduled procedure never occurs. For example, when a two-hour surgical case is canceled on the day of surgery, the anesthesiologist or CRNA, nursing staff and OR resources are already committed. In most cases, that time cannot be recovered or backfilled on short notice.
The result of such scenarios is lost surgical capacity in an environment where OR access, workforce utilization and procedural efficiency have never been more critical.
From Medication Holds to Risk-Based Assessment
An important shift has occurred in perioperative GLP-1 management. Earlier recommendations emphasized withholding GLP-1 medications prior to elective procedures. As clinical experience and evidence have evolved, the American Society of Anesthesiologists (ASA) and collaborating surgical societies have transitioned toward a more individualized, risk-based approach.
Today, the focus is increasingly on identifying patients at elevated risk for delayed gastric emptying rather than applying universal medication-holding recommendations. This approach balances two competing priorities: minimizing aspiration risk while avoiding unnecessary interruptions in medications that provide significant benefits for diabetes, obesity and cardiovascular disease management.
The Growing Role of Preoperative Screening and Gastric Ultrasound
As organizations adapt to evolving guidance, preoperative screening has become one of the most effective tools for preventing avoidable delays and cancellations. Standardized medication screening, symptom assessment and proactive patient communication allow potential concerns to be identified days before surgery rather than hours before anesthesia induction.
In addition, point-of-care gastric ultrasound is emerging as a valuable tool in selected patients. When uncertainty exists regarding gastric contents or aspiration risk, gastric ultrasound can provide real-time information that helps anesthesia providers determine whether surgery can safely proceed, whether modifications to the anesthetic plan are warranted or whether postponement is appropriate.
Looking Ahead
National survey data indicate that approximately one in eight U.S. adults have used a GLP-1 medication, underscoring how rapidly these therapies have become integrated into routine clinical care and why perioperative teams must be prepared to manage their implications.
The long-term impact of GLP-1 medications will likely be positive, with healthier patients and reduced rates of obesity-related disease representing meaningful progress for healthcare.
For anesthesia leaders, the near-term challenge is operational excellence. In an era where every operating room minute matters, the organizations that succeed will be those that transform the perioperative challenges of GLP-1 therapy into opportunities to enhance patient safety, protect surgical capacity and drive operational performance.
