Table 2 Summary of the RESET study control and intervention protocols

From: Multicentric randomized clinical trial to evaluate the long-term effectiveness of a motivational intervention against smoking, based on the information obtained from spirometry in primary care: the RESET study protocol

Control group: brief anti-smoking intervention Intervention group: spirometry report
In a 5-minute intervention, the health professional will make a clear, firm, personalized proposal recommending smoking cessation, in an empathic and respectful manner. He or she will clearly explain to the smoker that the most important decision the individual can make to achieve better health is to quit smoking, and will provide written informational materials that describe the benefits of giving up smoking. In a 15-minute intervention, the health professional will carry out an intervention with the same content as the brief anti-smoking intervention and will provide personalized information about the spirometry results, clearing up any patient doubts about spirometry or any other questions that come up during the visit.
The materials are provided by the “Smoke-Free Primary Care” program of the Catalan Society of Family Medicine and the Public Health Agency of Catalonia and are regularly used in primary care offices for brief anti-smoking interventions. If spirometry values are within normal range, the patient will be informed that his or her pulmonary function has not yet deteriorated and that this would be a good time to quit smoking.
  If spirometry values indicate airway obstruction (FEV1/FVC <70 %), the patient will be informed that he or she could have chronic obstructive pulmonary disease due to smoking, and that the most important treatment measure is to quit smoking.
  If spirometry values show airway restriction, the patient will be informed that his or her pulmonary function could be affected and will be advised to continue with the pulmonary tests normally administered in that primary care center.
  In addition, the patient will be informed of his or her lung age (i.e., the mean age of a nonsmoker with the same FEV1) compared to his or her chronological age, in order to illustrate the possible deterioration of the lungs as a result of smoking.
