Having established an ambulatory service for patients with suspected and proven PE, we reviewed our outcomes. All patients referred from June 2010 to May 2012 were analysed. Of 971 patients referred, 905 underwent complete assessment (66 admitted as ineligible). 754 (77.7%) patients were discharged and required no follow-up. 96 (10.6%) patients had PE confirmed of whom 70 (72.9%) were managed as outpatients. 14 (1.6%) patients have died since attending the clinic; no death was related to PE. This audit shows that ambulatory investigation and management of selected low risk patients with suspected PE is safe and reduces hospital admissions.

To assess whether daily variations in three parameters recorded by non-invasive ventilation (NIV) software (respiratory rate (RR), percentage of respiratory cycles triggered by the patient (%Trigg) and NIV daily use) predict the risk of exacerbation in patients with chronic obstructive pulmonary disease (COPD) treated by home NIV. ⋯ This proof-of-concept study shows that daily variations in RR and %Trigg are predictors of an exacerbation.
