About this study

Cigarette smoking is associated with surgical complications, including wound healing and surgical site infection. However, the association between smoking status and postoperative wound complications is not completely understood. Our objective is to investigate the effect of smoking on postoperative wound complications for major surgeries.

Read the detailed description

Smoking at the time of surgery is recognized as a risk factor for cardiovascular, respiratory, and wound-related perioperative complications. Wound-related complications can prolong hospital stays, increase hospital resource utilization, and pose an obvious threat to patient recovery. A brief statement on perioperative smoking cessation about smoking impacting wound healing was published by the American Society of Anesthesiologists' Task Force on Smoking Cessation. Recently, a consensus statement on perioperative smoking cessation by Society for Perioperative Assessment and Quality Improvement (SPAQI) mentioned that smoking cessation should be done as soon as practicable with surgical scheduling. More extended abstinence is associated with lower rates of wound healing complications.

Several studies have described smoking harms wound healing in specific operations, such as plastic surgery, breast surgery, gastrointestinal surgery, and hip surgery. They found surgical site infection and wound delayed healing more frequently in smokers. But in a few small studies and some surgery, conflicting results were found. Besides, risk factors associated with wound complications include infection, smoking, aging, malnutrition, immobilization, diabetes, vascular disease, and immunosuppressive therapy.

This study aims to determine the impact of smoking on wound complications for all kinds of major surgeries. To clarify the risks, our study uses the updated National Surgical Quality Improvement Program (NSQIP) database to find if patients who were active smokers are more likely to have wound-related complications postoperatively. We hypothesized that the active smoking population will have increased infectious complications and wound dehiscence compared with the nonsmoking population.

Questions about this trial

What is this clinical trial studying?

An observational study of Wound Complication and Smoking, run by Taipei Medical University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

wound complications (time frame: within 30 days after the primary procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2021.
