Knowledge of fractional exhaled nitric oxide use among doctors working in a local respiratory department

cut-off of <12 months and ≥12 months working in our respiratory department was set to check whether there is a statistical significance in the knowledge of FeNO testing amongst these two categories. The participants working in the department for <12 months are junior trainees currently rotating in the ABSTRACT INTRODUCTION The aim of this survey is to assess the knowledge regarding fractional exhaled nitric oxide (FeNO) testing among our junior and senior physicians currently working within the respiratory department. METHODS All medical doctors above foundation level working in the respiratory department for at least 3 months at Mater Dei Hospital were asked to complete a questionnaire with a total of 19 true or false questions. Questions were based on current international guidelines and recommendations. RESULTS Our cohort included a total of 25 doctors. The mean age of experience working as a physician was 8 years; 84% of doctors (n=21) were aware that FeNO testing is available at our hospital. Questions assessing clinical indications and interpretation of FeNO in asthma and different respiratory conditions showed overall significantly better results between junior and senior trainees (p=0.013), though still lacking in certain aspects especially in conditions unrelated to asthma. CONCLUSIONS Our results show that doctors working in our department are overall knowledgeable about the use of FeNO in relation to the diagnosis and management of asthma. However, its use and interpretation in relation to other respiratory conditions and co-morbidities is lacking. This emphasizes the need to educate local respiratory trainees further on FeNO testing.
