Sang Haak Lee, M.D., Ph.D., pulmonologist and professor of medicine at St. Paul's Hospital and the Catholic University of Korea College of Medicine, and colleagues developed a yearlong cessation program that provided financial incentives to a team of 28 health care workers at St. Paul's Hospital in Seoul, South Korea. The researchers evaluated whether implementing a team approach in the workplace, where the team they belong to is rewarded financially when co-workers who smoke and are placed on a cessasation program have succeeded, could improve motivation to quit smoking, increase smoking cessation rates and keep former smokers from resuming the habit.

When the smokers participating in the program remained smoke-free, the team they belong to as a whole received a financial incentive of 50,000 won (about $45) for each successful participant at one week and one month. If the smokers in the team remained abstinent for a longer time period, the team was given a collective incentive of 100,000 won (about $90) for each success of the participant at 3 months and 6 months respectively. The team incentive resulted in increased emotional support on part of the rest of the team members whereas the encouragement from such non-smoking co-workers created more pressure on smokers to succeed in the program. The researchers awarded money to the teams based on team effort -- for how many co-workers the team has succeeded to encourage and support the cessation effort -- rather than on individual effort.

Abstinence rates at three, six and 12 months were 61 percent, 54 percent and 50 percent, respectively, according to Lee.

"In terms of efficacy, the abstinence rates were relatively high for a prolonged period in the team-based approach compared with those previously reported," he said. "We postulated that team-based intervention not only encouraged participants' motivation to quit smoking within the workplace, but also potentiated maintenance to stay abstinent due to peer pressure and peer support."

Despite antismoking policy measures introduced in the mid-1990s, smoking is a leading cause of death in South Korea. Likewise, smoking remains the world's leading cause of preventable death, Lee said.

Although the study was limited by a small number of participants, according to Lee, the researchers believe that this information could be used elsewhere to develop workplace smoking cessation programs.

"Many employees spend the majority of their day in a workplace environment, and the workplace has a number of advantages for smoking cessation intervention," he said.
