Protocol for regional implementation of collaborative lung function testing.

The potential of forced spirometry (FS) testing for diagnosis, monitoring and management of chronic respiratory patients is well established1-3 such that FS is a pivotal test in both respiratory medicine and primary care. Moreover, it also shows potential in the informal care scenario: that is, in pharmacy offices for case-finding purposes4,5 and for self-management in selected patients.6,7 We acknowledge that well-designed studies8 have failed to show practical benefits of FS for asthma and COPD diagnosis and management in primary care. However, it has been demonstrated that historical limitations for extensive use of FS in primary care, because of suboptimal quality of testing, can be overcome by offline remote support by specialised professionals.9,10 Large-scale deployment of this type of setting has generated evidence of cost-effectiveness..
