The Use of PCR for Respiratory Virus Detection on the Diagnosis and Treatment Decision of Respiratory Tract Infections in Iraq

Abstract

Diseases of the respiratory system are a common cause of antibiotic prescription in Iraq and worldwide. Technology has been recently used for its diagnosis, such as the Film Array Respiratory Panel. This study aims to identify the correlation between the diagnosis and treatment of respiratory tract infections with the result of polymerase chain reaction (PCR) for respiratory viruses. A descriptive, cross-sectional, retrospective study included 134 patients treated at Alkharama Hospital and the Private Hospital in Baghdad, Iraq, in the period from January 2020 to March 2020 For all cases, the results of the panel and the treatment received by the patients were analysed. 58% received antibiotic treatment upon admission, 13% combined treatment (antibiotic + antiviral), 27% received symptomatic treatment, and 2% were treated with the first-instance antiviral. After the result, 38% continued with antibiotics, 30% with antibiotics and antivirals, 13.8% with antivirals and 18.2% with symptomatic treatment. Despite the worldwide alarm over antimicrobial resistance, patients continue to be treated with antibiotics due to a situation that is influenced by several factors.
