Background: Self management of anticoagulation: a randomised trial (SMART) was the first large scale UK trial to assess clinical and cost effectiveness of PSM of oral anticoagulation therapy compared to routine care. SMART demonstrated that whilst PSM was as clinically effective as routine care, it was not as cost effective. SMART adds to the growing body of trial data to support PSM however there are no data on clinical effectiveness and cost of PSM in routine care.
Objective: To evaluate clinical effectiveness of PSM compared to routine care outside trial conditions.
Methods: A retrospective multi centred matched control study. 63 PSM patients from primary care in the West Midlands were matched by age and International Normalised Ratio (INR) target with controls. INR results were collected for the period 01/07/03 – 30/06/04. The primary outcome measure was INR control.
Results: 38 PSM and 40 control patients were recruited. INR percentage time in range was 70% PSM v 64% control. 60% PSM were having a regular clinical review, 45% were performing an Internal Quality Control (IQC) and 82% External Quality Assurance (EQA) on a regular basis.
Conclusion: PSM outside trial conditions is as clinically effective as routine UK care.
