Smoking has harmful effects on nearly every organ of the body and causes seven million deaths worldwide every year.1,2 Although the prevalence of daily cigarette smoking in Hong Kong has decreased from 23.3% in 1982 to 10.5 % in 2015, there are still 641,300 daily smokers3 and 400,000 hospitalisations per year that are attributable to smoking.4 Having a disease and requiring medical attention present an excellent 'teachable moment' and opportunity for initiating smoking cessation in patients, because they will be more likely to be motivated to alter their habits and improve their health. However, cigarette smoking is addictive and quitting is very difficult, with a high rate of relapse, particularly among patients with chronic diseases.5 During the past decade, we have conducted several trials on promoting smoking cessation to smokers with chronic diseases, including cardiac,6 type 2 diabetes mellitus,5 and cancer.7 We found that many smokers with chronic diseases had a long smoking history, high nicotine dependency, no quit attempt, and no intention to quit. Results of these studies indicated that about 68% smokers with cardiac diseases, 70% with diabetes mellitus and 73% with cancer recruited in Special Out-Patient Clinics (SOPC) were still in the pre-contemplation stage. We revealed that most Hong Kong smokers with chronic diseases perceived more barriers in quitting than benefits of quitting.7 Nevertheless, our previous smoking cessation interventions mostly focused on using brief interventions including stage-matched smoking cessation advices. Such interventions could be too brief and inadequate to make a great impact on such smokers. Moreover, we found that using strong warnings to communicate the risk of continued smoking might not be accepted by some of them. Hence, we need to develop and evaluate a more innovative intervention to enhance the effectiveness in promoting smoking cessation for smokers with chronic diseases. Most importantly, the new strategy should have good potential implementation in many clinical settings. Smoking has been found to be associated with physical inactivity,8 unhealthy diet,9 and drinking.10 The interrelationship of health behaviours suggests that there could be a higher level of attribute that determines such behaviours together. Our previous studies11,12 showed that people with a general intention to promote their health are more likely to engage in desirable health-related lifestyle practices. In addition, research results showed that people once engaged in any desirable health-related lifestyle practices would progressively move to later stages of change for other health behaviours. Based on this concept, a general health promotion approach will be used to motivate smokers with intention to promote health to first engage in any desirable health-related lifestyle practices that are chosen by individual smokers, such as regular physical activity and healthy diet. It is anticipated that once they are engaged in any desirable health-related lifestyle practice they will eventually be more motivated to quit smoking. Setting: The study setting will be a SOPC of an acute public hospital (Tuen Mun Hospital). The Chief of Service of this unit agreed to offer support the application of this research project to be conducted in the hospital. This SOPC is chosen because of its previous participation in our RCTs on cardiac, diabetes, and cancer patients and has already been established a good collaborative relationship. In addition, Tuen Mun Hospital is one of the largest acute hospitals in Hong Kong and medical patients with chronic diseases who do not need hospitalization or are discharged will be followed up in its medical SOPC after discharging from the hospital. The capacity of this SPOC ensures the adequacy of eligible subjects to participate in this pilot study.
