Investigation on the application status of aerosol inhalation by suburban patients with chronic obstructive pulmonary disease

Abstract

Objective To investigate the application status of aerosol inhalation by suburban patients with chronic obstructive pulmonary disease （ COPD） .Methods A total of 82 patients with COPD were chosen by convenience sampling , and self-designed questionnaires were used to investigate their application of aerosol inhalation .Results Eighty-two questionnaires were handed out and 82 were recovered , with the effective rate of 100%.Patients hospitalized in respiratory department had statistically higher score in application of aerosol inhalation than those who were hospitalized in non-respiratory department （ t =9.27, P 〈0.01 ）.Linear correlation analysis showed that the score was in positive correlation with the patients ’ educational background , whether hospitalized in respiratory department , and whether examined upon further interview with doctors （ r=0.350, 0.728, 0.511, respectively;P〈0.01）.Logistic regression analysis indicated that whether hospitalized in respiratory department and patients ’ educational background were the main influencing factors （ R2 =0.58, 0.37, respectively ）.Conclusions To improve patients ’ ability of using aerosol inhalation correctly , professional skill trainings are necessary for nurses in non-respiratory department .
