Smokers face higher infection risk after hernia operations

 

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.

 

Complications developed in 6.34% of smokers and 4.72% of nonsmokers (P less than .001). Numerous kinds of complications were more common in the smokers prior to adjustment: death, return to the operating room, readmission, and transfusion plus wound, pulmonary, thromboembolic and cardiac complications.

The researchers adjusted their statistics to account for factors such as ethnicity, sex, body mass index, preexisting comorbidities, and type of hernia operation. They found that risk of all complications was higher in smokers, compared with nonsmokers (odds ratio, 1.30) as were several other complications: death (OR, 1.53), return to operating room (OR, 1.23), readmission (OR, 1.24), wound complication (OR, 1.36), sepsis/septic shock (OR, 1.31), pulmonary complication (OR 1.77-2.30) and cardiac complication (OR, 1.27-1.43).

Only transfusion (OR, 0.90) and thromboembolic (OR, 0.87) complications were less likely in smokers.

The researchers noted that the statistics don’t allow them to analyze whether it makes any difference if smokers quit shortly before their procedures. Still, Dr. Stulberg stands by his you-must-quit-smoking-before-surgery edict. “I believe that their active smoking habit is a bigger health threat than their asymptomatic hernia, and therefore feel the right thing to do as their physician is support them through their smoking cessation,” he said. “I offer counseling and nicotine replacement if needed. I have very good quit rates and would encourage other surgeons to do the same.”

 

Dr. Stulberg noted that he can’t point to evidence supporting his requirement that patients quit at least 3 months before surgery. “Most data out there says the farther away from your last cigarette, the better,” he said. “But there isn’t any magic to 3 months, other than I believe it will lead to a higher likelihood of permanent cessation.”

Northwestern Memorial Hospital and Northwestern University funded the study. Four of the nine authors, including Dr. Stulberg, report various disclosures that are not directly related to the study, including funding from government agencies, physician organizations, Health Care Services Corporation and Blue Cross Blue Shield of Illinois, Mallinckrodt, and Northwestern University. The other authors report no disclosures.
