Abstract
Introduction

Domiciliary oxygen therapy (DOT) is a treatment that requires a high level of cooperation from patients due to the time it takes every day. A high level of non-compliance has been determined among patients receiving DOT. The aim of our study was to assess the level of non-compliance and the influence of active tobacco consumption on compliance.

Material and methods

Patients were monitored in the home using direct and indirect methods, to assess both compliance and tobacco consumption.

Results

The level of non-compliance detected by indirect methods was 22.6%, and 66.3% by direct methods. Tobacco consumption determined by indirect methods was 5.8%–8%, depending on the method used, and 16.2% when CO in exhaled air ≥10ppm was established as an indicator of tobacco use. The group of smokers complied with oxygen therapy for a significantly fewer number of hours per day (P<.001) than non-smokers.

Conclusions

There is a high level of therapeutic non-compliance and a significant percentage of patients receiving DOT continue to smoke. Compliance must be monitored, and the correct use of DOT must be emphasized. Additional efforts should also be made to help smokers with DOT to stop smoking, since continued smoking impacts negatively on therapeutic non-compliance.

Resumen
Introducción

La oxigenoterapia crónica domiciliaria (OCD) es un tratamiento que exige una colaboración muy importante por parte de los pacientes debido al elevado número de horas que debe realizarse. Se conoce que existe un elevado nivel de incumplimiento entre los pacientes con OCD. El objetivo de nuestro estudio ha sido valorar el nivel de incumplimiento y la influencia del consumo de tabaco activo sobre el mismo.

Material y métodos

Se ha realizado un control en el domicilio de los pacientes utilizando métodos directos e indirectos, tanto para valorar el nivel de cumplimiento como el de consumo de tabaco.

Resultados

El nivel de incumplimiento detectado por métodos indirectos es del 22,6%, y por métodos directos es del 66,3%. El consumo de tabaco determinado por métodos indirectos es del 5,8% o del 8% dependiendo del método utilizado y del 16,2% cuando se establece un nivel de CO en aire exhalado ≥10ppm como indicativo de fumador. El grupo de fumadores realiza un número de horas/día de oxigenoterapia significativamente menor (p<0,001) que los no fumadores.

Conclusiones

Existe un elevado nivel de incumplimiento terapéutico y un porcentaje importante de pacientes con OCD continúa fumando. Es preciso vigilar el cumplimiento, insistiendo en la necesidad de realizar bien la OCD, y se debe realizar también un esfuerzo añadido para ayudar a los fumadores con OCD a dejar de fumar, ya que mantener el consumo de tabaco contribuye a un mayor incumplimiento terapéutico.
