ABSTRACT
BACKGROUND: The literature shows that delayed or erroneous diagnosis of respiratory conditions may be common in primary care due to underuse of spirometry or poor spirometric technique. The Community Respiratory Assessment Unit (CRAU) was established to optimise diagnosis and treatment of respiratory disease by providing focused history-taking, quality-assured spirometry, and evidence-based guideline-derived management advice. AIMS: To review the service provided by the CRAU to primary care health professionals. METHODS: Data from 1,156 consecutive GP referrals over 4 years were analysed. RESULTS: From the 1,156 referrals, 666 were referred for one of five common reasons: suspected asthma, confirmed asthma, suspected chronic obstructive pulmonary disease (COPD), confirmed COPD, or unexplained breathlessness. COPD was the most prevalent referral indication (445/666, 66.8%), but one-third of suggested diagnoses of COPD by the GP were found to be incorrect (161/445, 36%) with inappropriate prescribing of inhaled therapies resulting from this misdiagnosis. Restrictive pulmonary defects (56/666, 8% of referrals) were overlooked and often mistaken for obstructive conditions. The potential for obesity to cause breathlessness may not be fully appreciated. CONCLUSIONS: Misdiagnosis has significant financial, ethical, and safety implications. This risk may be minimised by better support for primary care physicians such as diagnostic centres (CRAU) or alternative peripatetic practice-based services operating to quality-controlled standards.

This is the second of a two-part unit on the use of emergency oxygen in adults. Part 1 outlined the main recommendations of the recently published British Thoracic Society guidance. It also examined managing breathlessness in non-hypoxaemic patients. This part discusses some potential changes to clinical practice and provides practical examples on administering oxygen to patients with acute asthma and COPD. It also outlines issues around administering oxygen that lack evidence and need good-quality studies.

The first in this two-part unit discusses new British Thoracic Society guidance on using emergency oxygen in adults. This is the first national guidance on this area and the implications for possible changes to practice are highlighted here. This part outlines the philosophy behind the guideline, the differences between hypoxaemic and hypercapnic patients and essential assessments for critically ill patients who need emergency oxygen. It also discusses using this therapy for patients with lung cancer in acute situations.
