Welcome to the IMPRESS website; a joint initiative between the two leading respiratory clinical societies in the UK: the General Practice Airways Group (GPIAG) and the British Thoracic Society. The site contains all you need to know to commission or provide high quality patient-centred services, integrated between primary and secondary care. The focus is on COPD and asthma, which are the conditions most likely to require a mix of primary and secondary care over a person’s lifetime. The website is designed to equip commissioners with an understanding of the evidence-base, standards, workforce issues, and tricky issues such as interpreting data and coding correctly. Equally, it offers clinicians practical tools; an appreciation of how their services might be commissioned in the future, and suggestions of how they best engage with the commissioning process.
