4 Interstitial lung disease investigations

4 Interstitial lung disease investigations

4.1 Only carry out bronchoscopy and pulmonary function tests if the patient urgently needs them and if the results will have a direct impact on their care, because these tests have the potential to spread COVID‑19. Plan investigations following NICE's guideline on arranging planned care in hospitals and diagnostic services or UK government guidance on infection prevention and control for COVID-19 as appropriate.

4.2 If supervised spirometry is not possible, consider using home spirometry to get measurements needed for treatment decisions if the equipment and support are already available.

4.3 Consider alternatives to patients attending hospital for blood monitoring while on antifibrotic drugs or immunosuppressants, for example, community blood monitoring services.
