title: Impact of Patients' Communication with the Medical Practitioners, on Their Adherence Declared to Preventive Behaviours, Five Years after a Coronary Angiography, in Luxembourg.
abstract: BACKGROUND
  Patients of the National Institute of Cardiac Surgery and Interventional Cardiology in Luxembourg who underwent coronary angiography were surveyed for hypertension, hypercholesterolemia, diabetes and overweight/obesity between 2008/9 and 2013/4. For each cardiovascular risk factor (CVRFs), we analysed the associations between the quality of the patients' communication with the medical practitioner and their adherence declared to preventive behaviours.
  
  
  METHODS
  1,289 completed a self-administered questionnaire on communication with the medical practitioner (P'Com-5 items scale; Cronbach 0.87). 61.8% stopped smoking, 57.9% reduced or stopped their consumption of salt, 71.9% of fat, and 62.8% of sugar, and whereas 65% increased their consumption of fruit and vegetables and 19.8% increased their physical activity. Around 37% reported having made changes following their doctor's advice. 90% were followed by a cardiologist and 95.9% by an attending physician.
  
  
  RESULTS
  No link was observed between declaration of physical activity, smoking, fats, and quality of communication. Significant associations: for increased consumption of fruit and vegetables was linked with the quality of doctor-patient communication when patients were overweight (OR = 1.081), obese (OR = 1.130), hypercholesterolemic (OR = 1.102), hypertensive (OR = 1.084) or diabetic (OR = 1.103). Reduction in salt intake was linked only to patients with hypertension (OR = 1.102), whereas reduction or cessation of sugar consumption was linked to overweight (OR = 1.093), and more so obese, (OR = 1.106), hypercholesterolemics (OR = 1.103) and diabetics (OR = 1.173).
  
  
  CONCLUSIONS
  Good doctor-patient communication was related to nutrition, particularly increased consumption of fresh fruits and vegetables. Accurate perception of CVRFs by both patients and medical practitioners is essential for CV protection. The aim of instructing patients is to encourage them to make informed decisions about how to change their lifestyle. In routinely, P'Com-5 scale can collect data to assess the improvement of the professional skills. It can be used in medical training to enhance the quality of the therapeutic communication, especially for nutritional coaching, and to evaluate its efficacy in reducing CVRFs.
