Aim The National Patient Safety Agency (NPSA)¹ identified heparin as a major cause of adverse events associated with adverse incidents, including some fatalities. By ensuring good communication, this should be associated with risk reduction.¹ The aim of this study was to ensure there is clear anticoagulation communication on discharge, from the paediatric intensive care unit (PICU) electronic prescribing system (Philips), to the paediatric cardiac high dependency unit and paediatric cardiac ward. To investigate whether the heparin regimen complies with the hospital’s anticoagulant guidelines and if there is any deviation; that this is clearly documented. To find out if there is an indication documented for the heparin regimen chosen and if there is a clear long term plan documented for the patient, after heparin cessation.

Methods A report was generated for all patients who were prescribed a heparin infusion on PICU, between 1st January 2018 and 30th June 2018, from the Philips system. All discharge summaries from the PICU Philips system were reviewed. Only paediatric cardiac patients were included that had a heparin infusion prescribed on discharge, all other discharge summaries were excluded from the study. Each discharge summary was reviewed in the anticoagulant section; for the heparin regimen chosen, whether it complies with the hospital’s anticoagulant guidelines and if there was any deviation whether this was documented. The indication documented of which heparin regimen was chosen and whether a clear long term plan was documented after heparin cessation; for example if the patient is to be transferred onto aspirin, clopidogrel, warfarin or enoxaparin.

Results 82 discharge summaries were reviewed over the 6 month period between 1st January 2018 and 30th June 2018; 16 were excluded as were not paediatric cardiac, leaving 66 paediatric cardiac discharge summaries that were reviewed. 45 out of 66 (68%) complied with the hospital’s heparin anticoagulation guidelines. Of the 32% that deviated from the protocol; only 33% (7 out of 21) had a reason documented. Only 50% (33) of the summaries reviewed had an indication for anticoagulation noted on the discharge summary and 91% of discharge summaries had a long term anticoagulant plan documented.

Conclusion The electronic prescribing system can help to ensure a clear anticoagulation communication as shown by 91% of the anticoagulation long term plan being clearly documented; making it a more seamless patient transfer. On the Philips PICU electronic prescribing system there is an anticoagulant section on the discharge summary that has 3 boxes that need to be completed; heparin regimen, indication and anticoagulation long term plan. However, despite these boxes; deviations from the anticoagulant protocol were poorly documented as highlighted by only 33% having the reason highlighted in the discharge summary, only 50% of the indications were documented. Despite having prompts for this information on the discharge summary, the medical staffs needs to be aware to complete this information, in order to reduce potential medication errors and risk.
