INTRODUCTION: Asthma and chronic obstructive pulmonary disease (COPD) are ongoing concerns to the health system. Poor inhaler technique results in less than optimal delivery of medicine to the lungs and consequent inadequate symptom control. AIM: This study aimed to assess inhaler technique amongst people with asthma and/or COPD. The secondary aims were to investigate who provided education on inhaler technique and whether age, gender or ethnicity was associated with poor inhaler technique. METHODS: People with asthma or COPD who presented to a community pharmacy with a prescription for a respiratory inhaler were invited to participate in the study. Participants completed a brief questionnaire and had their inhaler technique assessed against a standard checklist. RESULTS: There were 103 participants from 26 pharmacies, 86 with asthma and 17 with COPD. Just over half (52.5%) of the assessments indicated good inhaler technique, with 68% of people using the Turbuhaler having good technique compared to 53% for the pressurised metered dose inhaler (pMDI) with spacer and 47% for the pMDI alone. The majority of people (76%) received their initial inhaler technique instruction from their doctor. Over half of participants did not recall having their inhaler technique rechecked. DISCUSSION: After prescribing appropriate therapy, correct inhaler technique is a cornerstone of achieving adequate therapy. Rechecking inhaler technique is a gap in care that needs to be addressed from an interdisciplinary perspective. KEYWORDS: Asthma; chronic obstructive pulmonary disease; dry powder inhalers; metered dose inhalers; spacer inhalers

suMMAY The coronary angiograms of 120 consecutive patients under 40 years of age were examined. Ten new cases of myocardial infarction with normal coronary arteriogram were identified (group 1) and compared with 30 cases of myocardial infarction and obstructive coronary disease (group 2). Heavy cigarette smoking was the sole major risk factor in group 1. Patients in group 2 smoked as well but most also had hypercholesterolaemia or hypertension. Pre-and postinfarction angina was rare among the patients with myocardial infarction and normal coronary arteriogram, and recanalisation after smokinginduced thrombotic occlusion is thought to be the most likely mechanism. Smoking-induced thrombosis is only likely to be recognised in special circumstances, when it develops in apparently normal coronary arteries, is followed by recanalisation, and is complicated by infarction as a permanent marker of previous obstruction to regional myocardial blood flow. Thrombotic occlusion of a "normal" coronary artery without recanalisation will only be recognised when infarction is fatal. If smoking can predispose to thrombosis in "normal" coronary arteries, it may be even more likely to accelerate thrombosis in atheromatous coronary arteries. The importance of recognising group 1 may well be in relation to the much commoner group 2.
