In a hurry? Make sure you know
- Full blood count (recent, preferably that day)
- Vital signs and temperature
What history should JMOs know/collect?
- History of bleeding or bruising
- History of deep venous thrombosis or pulmonary embolism – provoked or unprovoked? Superficial or deep? How long ago was the VTE?
- What anticoagulant the patient is on, indication and the time of last dose
- Contraindications to anticoagulation?
- Any new drugs which have been started
- History of haematological malignancy and treatment
- Regarding derangements in full blood count: new or chronic, trend of any abnormalities, correlation with previous results outside of hospital is also valuable
- What haematologist (if any) the patient is known to/has seen in the past
What examinations and investigations should JMOs perform/collect results of?
- Vitals, especially temperature
- Haematological examination if relevant (lymphadenopathy, splenomegaly, hepatomegaly)
- Full blood count and differentials including the neutrophil count
- Creatinine clearance (based on weight) – required for most anticoagulants
What additional information would impress you?
- Details of recent chemotherapy treatment, including timing
- Previous blood counts and/or scan results
What are common mistakes/omissions made by JMOs?
- Use your online local resources for reversal of anti-coagulation that are available on your hospital intranet.
- Haematology can assist you in how to reverse coagulation but typically cardiology should be consulted regarding risks/ benefits of reversal in patients in atrial fibrillation and/or mechanical valves
