Study hypothesis
Objectives of this study were to test the efficacy, cost effectiveness and safety of using a nurse-led clinic in primary care, involving near patient testing (NPT) and computerised decision support software (CDSS) for therapeutic oral anticoagulation management. The null hypothesis tested was that anticoagulation care can be provided at least as well in primary care as compared to routine hospital management based on a variety of previously validated and novel clinical outcome measures.

Thromboembolic disease
Intervention
A randomised controlled trial using 12 primary care practices in Birmingham, UK (9 intervention and 3 control). The study used 2 control populations; patients individually randomly allocated as controls in the intervention practices (intra-practice controls), and all patients in the 3 control practices (inter-practice controls), included to estimate any Hawthorne effect amongst the intervention controls. Patients from the 9 intervention practices were randomised to intervention (practice based anticoagulation clinic) or control (traditional attendance at hospital clinic).
