Reducing Antibiotic Misuse through the Use of Point-of-Care Tests in Germany: A Survey of 1257 Medical Practices

Abstract

Though more than 80% of acute pharyngitis (AP) cases have a viral etiology, it remains one of the most common causes for the unnecessary prescription of antibiotics (ABs). Half of patients receive antibiotics in general practice. Point-of-Care Tests (POCTs) distinguish between bacterial and viral pharyngitis. The objective of this study was to evaluate the use of POCTs using throat swabs to detect β-Streptococcus pyogenes Group A (strep A) infection among patients with sore throat/acute pharyngitis in primary care practices across Germany. A study was conducted in 1257 primary care practices. Two questionnaires were administered concerning frequency, POCT results and whether antibiotics were prescribed. Of the 1257 physicians, 60% used POCTs. Of these, 25% used a POCT before prescribing an antibiotic, 39% in cases of severe sore throat, 40% in cases of long-lasting pharyngitis and 25% in other cases. In total, 83% considered the adoption of POCTs in everyday practice to be important or very important for the diagnosis of strep A, 90% considered it important or very important for achieving a more sensible use of antibiotics and the prevention of bacterial resistance and 80% considered it important or very important for justifying to patients whether or not an antibiotic is needed. POCT results and information on AB prescriptions were available for 583 patients. Of these, 22.5% tested positive for strep A, and 21.8% were prescribed antibiotics. Our study shows that the use of swab tests in patients with sore throat in primary care practices results in high levels of physician satisfaction and can strongly reduce the misuse of antibiotics in clinical practice.
