Anticoagulation and antiplatelet therapy in paediatric cardiac patients (1180)

Objectives: To allow standardised anticoagulation practice in paediatric cardiac patients and provide guidance for staff administering or prescribing anticoagulation therapy. This guideline does not replace the clinical experience and judgement of the practitioners looking after the patient. When a tailored patient-specific approach to anticoagulation is required, the rationale and collegiate discussion must be clearly documented in the patient medical record.

Scope: This guideline applies to any cardiac patient being prescribed or administered anticoagulation therapy.

Audience: All healthcare professionals prescribing, supplying or administering anticoagulation therapy should be aware of this guideline.

Evidence method

These guidelines have been written in consultation with the medical literature using the current gold standard for anticoagulation practice which reviews the best levels of evidence available. There are few randomised controlled trials (RCT) available in this area and the majority of evidence is level 3. The guidelines incorporate extensive consultation with intensive care, cardiology, cardiac surgery, haematology and pharmacy taking into consideration local practice, as well as current practice guidelines from other paediatric cardiac surgical centres. 

These guidelines will be reviewed with reference to clinical governance including review of clinical incidents and audit and will be reviewed every 3 years, or sooner if indicated.
