Mobile device: a useful tool to teach inhaler devices to healthcare professionals.

Background: Proper inhaler device usage is paramount for control of underlying obstructive airway disease. Hence, education to healthcare professionals who will eventually educate patients need to be done effectively. We developed an application for mobile devices for education on six medical inhaler devices, the metered-dose inhaler (MDI), Turbuhaler, Accuhaler, Breezhaler, Ellipta and Respimat, and studied if there were any difference between the application and the manufacturer's instructions on inhaler technique.

Blood eosinophil count correlates with severity of respiratory failure in life-threatening asthma and predicts risk of subsequent exacerbations.

Background: An elevated blood eosinophil count when asthma is stable predicts exacerbations and therapeutic response to corticosteroids or biologics targeting eosinophils. Few studies have examined the prognostic value of blood eosinophils measured at exacerbation.

Aim: To elucidate the relationship between a spot blood eosinophil count-measured at the onset of a life-threatening asthma exacerbation-with indices of exacerbation severity and risk of subsequent exacerbations.

Play and Learn with Patients-Designing and Evaluating a Serious Game to Enhance Nurses' Inhaler Teaching Techniques: A Randomized Controlled Trial.

To describe the development and evaluation of a nurse-patient interactive serious game in improving nurses' self-efficacy and performances in teaching the correct inhaler technique. : The technology, pedagogy, and content knowledge (TPACK) framework was applied to guide the development of the serious game. The learning effectiveness of the serious game was evaluated through a randomized controlled trial that involved 46 registered nurses.
