Assessment of Inhalation Technique in Clinical and Functional Control of Asthma and Chronic Obstructive Pulmonary Disease

Abstract

Acta Med Port 2015 Nov-Dec;28(6):702-707 RESUMOIntrodução: A doença pulmonar obstrutiva crónica e a asma afectam quase 300 milhões de indivíduos em todo o mundo. A terapêutica inalatória associa-se frequentemente a erros na técnica realizada reduzindo a eficácia e adesão. Objectivo: Avaliar a técnica inalatória e sua relação com o controlo clínico e funcional em asma e doença pulmonar obstrutiva crónica. Material e Métodos: Estudo transversal analítico incluindo doentes com asma e doença pulmonar obstrutiva crónica medicados com dispositivos inalatórios. Recolheram-se dados demográficos e existência de ensino prévio da técnica. Avaliou-se a técnica inalatória em: Passo 1 -expiração prévia; Passo 2 -activação do dispositivo; Passo 3 -inspiração; Passo Step 1 -device activation;Step 2 -previous expiration;Step 3 -inspiration;Step 4 -end inspiratory pause. Teaching inhalation technique has a positive impact on its future performance. Most patients make mistakes, affecting clinical control in asthma, although in chronic obstructive pulmonary isease no relation was found. This is an ongoing work that aims to reevaluate inhalation technique after patients' education and its further impact.

Educational interventions to improve inhaler techniques and their impact on asthma and COPD control: a pilot effectiveness-implementation trial

“…, 3 This study was performed in the context of an interventional trial, with the aim of assessing the impact that an educational intervention to improve inhaler technique has on the clinical and functional control of asthma and COPD. Preliminary results containing the cross-sectional baseline analysis of the patients enrolled in the trial have previously been published 4 . The results suggest a significant relationship between the number of errors committed and the level of clinical and functional control achieved in asthma patients.…”

Inhaler Review in Older Adults with Asthma or COPD: A Cost‐Effectiveness Study and a Perspective in Portugal

“…Asthma and chronic obstructive pulmonary disease (COPD) affect up to 10% of the population . Inhaled therapy is the main treatment pathway used, but most patients use devices incorrectly, frequently with critical errors, thereby contributing to poor clinical control and increased risk of exacerbations . In addition, many studies showed that poor clinical control also leads to increased costs in health services .…”

“…1 Inhaled therapy is the main treatment pathway used, but most patients use devices incorrectly, frequently with critical errors, thereby contributing to poor clinical control and increased risk of exacerbations. [2][3][4][5] In addition, many studies showed that poor clinical control also leads to increased costs in health services. [6][7][8][9] However, true estimates of the burden due to asthma and COPD are unavailable because direct and indirect costs are difficult to quantify, and different parts of the world report different estimations.…”

Inhaler Technique Education and Exacerbation Risk in Older Adults with Asthma or Chronic Obstructive Pulmonary Disease: A Meta‐Analysis

“…Inhaled therapy is the most widely used treatment, but up to 90% of individuals used incorrect technique in clinical studies, partly because the extensive variety of inhalers and their technical specifications create significant barriers to understanding of proper use . Although all available inhalers may be equally efficient when properly used, there are various device‐ and person‐related factors that may significantly influence performance . Poor inhaler technique is associated with worse symptom control and leads to greater healthcare resource consumption and costs …”

“…6 Although all available inhalers may be equally efficient when properly used, 7 there are various device-and person-related factors that may significantly influence performance. [8][9][10][11] Poor inhaler technique is associated with worse symptom control 12,13 and leads to greater healthcare resource consumption and costs. 14 Some studies have showed that teaching inhaler technique may lower the risk of exacerbations and death in these individuals, 2,3,[15][16][17] but the effect of teaching decreases with time, indicating the importance of regular reassessment.…”
