CHICAGO — Patients who develop alcohol withdrawal syndrome (AWS) after major surgery face significantly higher risks of complications, longer hospital stays, and increased health care costs, according to a study published in the Journal of the American College of Surgeons ( JACS ). The findings underscore the need for screening before surgery and targeted interventions.
Using the National Inpatient Sample (2016–2019), researchers analyzed data from 3 million adults who underwent major operations, including colectomy, cardiac surgery, and liver resection. Among them, 16,504 (0.5%) were diagnosed with AWS, including 6,591 (0.2%) with life-threatening delirium tremens (DT). DT is a severe form of alcohol withdrawal that can include shaking, confusion, and hallucinations.
“AWS is a preventable complication, yet it’s often overlooked in surgical planning,” said lead author Timothy M. Pawlik, MD, PhD, MPH, FACS, surgeon-in-chief at the Ohio State University Wexner Medical Center. “Our study shows that proactive screening and multidisciplinary care — involving surgeons, social workers, and addiction specialists — can save lives and reduce costs.”
The study highlights actionable strategies to improve outcomes:
“A patient recovering from major surgery shouldn’t also battle withdrawal,” said Dr. Pawlik, recalling a case where AWS led to aspiration pneumonia post-surgery. “We can change this by addressing alcohol use before surgery and ensuring safer recovery environments.”
Limtations: The study relied on administrative data, potentially underestimating AWS incidence. Long-term outcomes and treatment specifics (e.g., benzodiazepine use) were not assessed.

The American College of Surgeons is a scientific and educational organization of surgeons that was founded in 1913 to raise the standards of surgical practice and improve the quality of care for all surgical patients. The College is dedicated to the ethical and competent practice of surgery. Its achievements have significantly influenced the course of scientific surgery in America and have established it as an important advocate for all surgical patients. The College has approximately 90,000 members and is the largest organization of surgeons in the world. "FACS" designates that a surgeon is a Fellow of the American College of Surgeons.
