Mann Whitney U-test was used when comparing independent groups and Wilcoxon's signed-rank test was used when comparing dependent groups. Results: Of the 77 physicians, 38 participated only at baseline (group 1) and 39 participated in both registrations (group 2). The overall use of CRP nearpatient tests was 37% in group 1 and 28% in group 2 (Chi-square p < 0.001), and the overall use of Strep-A near-patient tests was 31% and 20%, respectively (Chi-square p < 0.001). When the Strep-A near-patient test was negative in pharyngitis/tonsillitis, antibiotics were prescribed to 45% in group 1 and to 12% by group 2 (Chisquare 0.003). Conclusion: In conclusion, this study showed that physicians, who were more inclined to complete audit participation, used near-patient tests and prescribed antibiotics more correctly, according to the national guidelines for respiratory tract infections, than physicians who discontinued the participation. To achieve a rational use of antibiotics, near-patient tests and prescription of antibiotics must be used according to guidelines.
