Assessment of the continued supervision and asthma management knowledge of patients possessing home nebulizers.

This paper describes the results of a questionnaire survey on some aspects of nebulizer use, nebulizer instruction, and features relating to the recognition and management of deteriorating asthma. The study population consisted of 90 children with home nebulizers attending a paediatric asthma clinic, and 200 asthmatic children and 200 asthmatic adults whose nebulizers had been purchased directly from a manufacturer in the U.K. The results suggest that follow-up supervision of the patients who bought their own nebulizers occurred in only approximately 25% of cases. Written information focusing on the management of symptoms was also lacking. Peak flow meters were being under-used. Although the majority (77-100%) of patients were aware of the '4 h rule' for repeat use of bronchodilator therapy at home, there was still some confusion about the acceptable time interval and action to be taken should the dose be required more frequently. Very few (32%) in the nationwide adult group had a crisis action plan should the nebulizer fail to produce relief. This paper recommends that a simple treatment and crisis plan should be included with the purchased nebulizer, highlighting the key areas to be discussed by the patients with the doctor or other medical professionals. Such a package may prevent the occasional disaster that can occur with unsupervised nebulized bronchodilator usage.
