Suspected Pulmonary Embolus Ambulatory - Pathway Click here for the Suspected Pulmonary Embolus Ambulatory Pathway guidance Key: General Notes ED/MAU/SRU/Acute GP/Amb-Care Start GP/SWASFT In-patient wards Symptoms suggestive of a Pulmonary Embolus Senior first assessment if possible Clinically assess patient and take a full history Any indicators of clinical instability including: Altered level of consciousness. Systolic BP of less than 100 mmhg. Heart rate of more than 110 beats per minute. Respiratory rate of more than 30 breaths per minute. Oxygen saturation of less than 94%. No - commence ambulatory pathway Perform a Wells Score Chest Xray, ECG, Bloods including FBC, UE, LFT, CRP, D- Dimer, clotting Yes senior clinical review Follow ambulatory pathway to expedite investigation if senior assessment indicates this is clinically safe Consider admission and initiate urgent management <4 Wells Score 4 Wells score 4 Do not perform D-Dimer. CTPA indicated. 1 Suspected Pulmonary Embolus Ambulatory - Pathway Page 1 of 4 2

4 4 hours 2 hours 1 2 Negative Consider alternative diagnosis D-Dimer Positive Request CTPA. If it is not possible to perform a CTPA on the same day then use clinical assessment, ECG and PESI score to ensure patient is suitable to go home after appropriate dose of anticoagulation. Consider community management Consider transfer to ambulatory care unit if patient in ED Positive for PE Consider whether PE was provoked or unprovoked. Anticoagulate as appropriate CTPA Negative for PE Consider alternative diagnosis including DVT Request troponin and combine with ECG findings and PESI score to assess whether patient is safe to be managed in the community Discharge to GP care if clinically stable End Suspected Pulmonary Embolus Ambulatory Pathway Page 2 of 4
