Smoking Cessation Before Surgery: A Small Intervention with a Big Impact

No smoking sign

When preparing patients for surgery, clinicians meticulously check labs, adjust medications, and manage chronic conditions. Yet one critical factor is still too often overlooked: smoking cessation. 

While it’s well-established that smoking increases surgical risk, it’s rarely integrated into perioperative pathways. That needs to change. 

The Evidence Is Clear 

Even a short period of abstinence from smoking, as little as four weeks, can lead to meaningful reductions in surgical risk, including: 

• Pulmonary complications such as pneumonia and respiratory failure 

•  Delayed wound healing and increased surgical site infections 

• ️ Higher risk of cardiovascular events like arrhythmias and myocardial infarction 

•  Increased likelihood of ICU admission and longer hospital stays 

A 2014 Cochrane Review found that preoperative smoking interventions reduce complications by up to 41%, especially when started a month or more before surgery. 

So Why Don’t More Hospitals Address It? 

In many hospitals, smoking status is recorded but rarely acted upon. Reasons include: 

• Time constraints in surgical consultations 

• Lack of standardized referral pathways 

• Misconception that it’s too late to make a difference 

But this is a missed opportunity. Smoking cessation isn’t just preventive care—it’s perioperative optimization. 

The Case for Embedding Smoking Cessation Into Pre-Op Workflows 

Integrating a simple cessation protocol into pre-op pathways can make a significant difference: 

1. Ask about smoking status at every surgical clearance visit 

2. Advise patients about the benefits of quitting—even temporarily 

3. Refer to counseling services, quitlines, or digital cessation tools 

4. Follow up during pre-op calls and reminders 

This can be done without adding much time to existing workflows, especially when supported by technology or care coordinators. 

A System-Level Intervention with System-Wide Benefits 

Hospitals that prioritize intensive preoperative smoking cessation see: 

• Fewer cancellations due to respiratory issues 

• Lower postoperative complication rates 

• Shorter lengths of stay 

• Higher patient satisfaction 

And ultimately lower costs.
