Smoking is a major environmental factor implicated in the development and clinical course of inflammatory bowel disease (IBD).1 Tobacco use has been associated not only with an increased risk of developing Crohn's disease (CD), particularly in Western countries, but also with unfavourable outcomes.1 Despite the controversy that smokers are less likely to develop ulcerative colitis (UC), the risks of smoking for people with both IBD conditions far outweigh the benefits. Despite all the evidence on the detrimental effects on health, smoking is still a prevalent behaviour among patients diagnosed with IBD.1 Therefore, patients should be encouraged to stop smoking according to the ECCO management guidelines.2
Nurses have become a mainstay in the care of patients with IBD and could play a critical role in the identification of patients smoking status and in the support for smoking cessation.3 However, data on nurses’ beliefs, attitudes and performance in this regard are scarce. In this study, we aim to explore the knowledge, attitudes and behaviours of nurses caring for IBD patients in relation to smoking cessation. For this purpose, we carried out a multicentric, observational, cross-sectional study based on a survey conducted among advanced practice IBD nurses, hospital and day care centre nurses who supervise IBD patients. The “Knowledge, Attitudes, Behaviours, and Organization (KABO) Questionnaire” was used as an evaluation instrument. The KABO questionnaire is a self-administered instrument specifically designed to assess factors relevant to smoking cessation implementation practices.4 The questionnaire assesses the brief smoking cessation intervention 5A model based on five strategies (1) Ask patients about smoking during every visit, (2) Advise all tobacco users to quit, (3) Assess smokers’ willingness to try to quit, (4) Assist smokers’ efforts with treatment and referrals, and (5) Arrange follow-up contacts to support cessation efforts. In addition, it explores individual cognitive and behavioural factors and smoking cessation support from an organizational-level.4
We collected surveys from 54 nurses caring for IBD patients in three public hospitals in Spain. The mean participant age±standard deviation was 43.9±11.4 years (range: 23–64): 94.4% were women, 63% were engaged in the care of IBD patients on a full-time basis and 37% on a part-time basis. Participants had 18.9±11 years of experience as nurses and 63% were advanced practice nurses. Regarding smoking habits, 51.8% (n: 28) had never smoked, 20.4% (n: 11) were current smokers, and 27.8% (n: 15) were former smokers. Only 11 (20.4%) had previous training in smoking cessation.
Survey results are summarized in Table 1. Only the Ask and Advise questions scored ≥7 (median score in a range from 0 to 10). The three questions regarding Follow-up scored quite poorly (≤1/10). Regarding cognitive and behavioural factors, participants obtained the highest scores in questions exploring individual commitment (30/40) but scored below average in individual skills (13.5/60). All organizational factors also scored low. Considering professional and personal backgrounds, advanced practice nurses scored significantly better in five out of the seven questions that assess the intervention 5A model. Nurses previously trained in smoking cessation scored better in individual skills. Never-smokers scored significantly better in individual commitment and in attitudes and beliefs.

Nurses play a key role in the control of IBD,3 but our data suggest that there are deficiencies in implementing smoking cessation interventions as part of their routine practice. Most nurses have never been trained in smoking cessation strategies and although commitment seems to be high, smoking cessation practices are not broadly implemented. Never-smoking status seems to positively influence nurses’ attitude, beliefs and individual commitment. Advanced practice nurses perform better that nurses without this specialized background. In line with our results, surveys conducted in gastroenterologist offices suggest that smoking cessation counselling is provided irregularly and many gastroenterologists do not feel comfortable discussing cessation strategies.5 As a conclusion, there is a need to integrate smoking cessation interventions as part of standard practice. Nurses play an important role in raising the issue of smoking cessation with IBD patients, but training is needed in techniques to deliver brief advice on smoking, better resources, and organizational support.
