Summary

The main objective of this study is to show that the repeated (twice-daily) measurement of expired CO during hospitalization helps reduce smoking.

Detailed description

Smoking in France represents 25 billion euros per year in care, hospitalizations and drugs and 78000 deaths / year are linked to a pathology attributable to this addiction. In addition, active consumption of cigarettes is a destabilizing factor for chronic respiratory diseases. During hospitalization for acute respiratory illness, evaluation of smoking cessation remains declarative. Although stopping advice and possibly nicotine replacement therapy are prescribed, no objective measure of smoking is performed to assess the adequacy of this attitude. This project aims to objectively evaluate smoking during hospitalization by measuring twice daily exhaled CO. The impact of this intervention on the duration of hospitalization and smoking 3m after initial admission will also be evaluated. Tobacco consumption patterns based on reason for hospital admission and background pathology will be highlighted. Secondary objectives include: * To measure the impact of expired CO measurement during hospitalization on the smoking status 1 month and 3 months after initial admission. * To determine smoking patterns during hospitalization according to reason for admission and background pathology. * To measure the effect of iterative CO measurement on the duration of stays. * To measure and compare the quality of life of patients. * To study the variability of expired CO measurements.

Conditions

• Hospitalization
• Smoking

Interventions

Type	Name	Description
OTHER	Twice-daily expired carbon monoxide (CO) measurements	Patients included in this arm will have expired CO measurements every morning and evening during their initial hospitalization.
OTHER	Minimal control	Patients included in this arm will have one expired CO measurement on the morning just after initial hospital admission and a second expired CO measurement one the morning prior to discharge.
