Smokers face higher infection risk after hernia operations

 

Key clinical point: Smokers are more likely than are nonsmokers to develop serious complications after elective hernia surgery.

Major finding: The adjusted risk of serious complications after elective hernia surgery is higher (odds ratio, 1.30) in smokers than nonsmokers.

Study details: Retrospective study of ACS NSQIP data on 220,629 patients in the United States (18% smokers) who underwent elective hernia operations during 2011-2014.

Disclosures: Northwestern Memorial Hospital and Northwestern University funded the study. Four of the nine authors reported various disclosures. The other authors report no disclosures.

Jonah Stulberg, MD, FACS, is stickler about requiring patients to stop smoking at least 3 months before hernia surgery. He even uses urine tests to confirm whether they actually quit. A study by Dr. Stulberg and his colleagues supports this approach: Current and recent smokers are significantly more likely to suffer serious complications over 30 days after elective hernia repair procedures.

The finding held up even after the researchers controlled for various factors. “Our findings are in agreement with other findings in higher risk surgeries, and they provide evidence that low-risk surgeries are not exempt from the risks associated with smoking,” said Dr. Stulberg in an interview. “Our data would suggest that there is significant clinical benefit to encouraging smoking cessation before elective hernia repair.”

Dr. Stulberg of Northwestern University in Chicago, is a coauthor of the new study, which was published online in the American Journal of Surgery.

The researchers launched the study to better understand how smoking affects complication rates in light of the fact that “surgeons in the U.S. tend to offer low-risk elective surgical procedures to patients who are actively smoking despite overwhelming evidence that smoking increases surgical risks,” Dr. Stulberg said.

The researchers tracked 220,629 patients in the American College of Surgeons National Surgical Quality Improvement Project (NSQIP) database who underwent several types of elective hernia repair from 2011 to 2014.

Just over 18% of the patients said they’d smoked over the past year; they were more likely to be younger (median age, 50 for smokers vs. 57 for nonsmokers). Smokers also were more likely to be black, to be underweight, and to consume two or more alcoholic beverages per day (P less than .05).

The researchers tracked serious complications in the 30 days after surgery such as death, sepsis, and readmission.
