The Sinus and Allergy Health Partnership has developed updated guidelines for the management of acute bacterial rhinosinusitis (ABRS). These guidelines, originally published in 2000, aim to educate healthcare providers and patients about the differences between viral and bacterial rhinosinusitis, reduce unnecessary antibiotic use, and provide recommendations for diagnosis and treatment. The guidelines emphasize the importance of distinguishing between viral and bacterial infections, as inappropriate antibiotic use can lead to increased resistance and adverse effects. The updated guidelines include recent data on management principles, antimicrobial susceptibility patterns, and therapeutic options. Key updates include a more detailed review of diagnostic modalities, such as serial sinus aspirate sampling, and a critical review of antimicrobial treatment options. The guidelines recommend specific antibiotics based on the severity of symptoms, recent antibiotic exposure, and the risk of resistant pathogens. The primary goal of antibiotic therapy is to eradicate bacteria, reduce symptom duration, prevent complications, and decrease the risk of chronic disease. The guidelines also address the challenges of diagnosing ABRS, the pathophysiology of the condition, and the role of various diagnostic modalities.The Sinus and Allergy Health Partnership has developed updated guidelines for the management of acute bacterial rhinosinusitis (ABRS).
