Estimating the cost-effectiveness of quality-improving interventions in oral anticoagulation management within general practice.

Objectives: A clinical trial, "Belgian Improvement Study on Oral Anticoagulation Therapy (BISOAT)," significantly improved the quality after implementing four different quality-improving interventions in four randomly divided groups of general practitioners (GPs). The quality-improving interventions consisted of multifaceted education with or without feedback reports on their performance, international normalized ratio (INR) testing by the GP with a CoaguChek device or computer-assisted advice for adapting oral anticoagulation therapy. The quality improvement in INR control versus baseline was similar in the four groups.

Further sequence analysis of the DNA regions with the Rhodococcus 20S proteasome structural genes reveals extensive homology with Mycobacterium leprae.

The sequence of the respective DNA regions downstream of the 20S proteasome structural genes prcB1A1 (6 kb) and prcB2A2 (3.3 kb) of Rhodococcus erythropolis NI86/21 were determined. A highly conserved gene organization was observed between the two clusters which differed significantly in G + C content (68.
