Retrospective Study on the Prevelance of Antimicrobial susceptibility pattern of staphylococcus species among patients attending Tertiary Care Hospital

Abstract

Staphylococcus is a group of bacteria that comprises of more than 30 species of medical importance. Among which Staphylococcus aureus causes most infections. 60% of Healthcare associated infections were caused by Staphylococcus aureus. They cause many different types of infections like Skin infections, which are the most common types. They also cause Bacteremia, an infection of the bloodstream, which can lead to sepsis. Bone infections, Endocarditis, Food poisoning and Pneumonia were also commonly caused by this bacterium. In past one-decade Staphylococcus species is gaining resistance to the antibiotics which is commonly used and also to the higher level antibiotics. This study mainly emphasis upon the prevalence of these species in a tertiary care hospital in order to frame the antimicrobial stewardship policy. The samples were received from the different departments and antimicrobial susceptibility pattern was interpreted. All the clinical specimens yielding Staphylococcus species were included in this study. 63% of Staphylococcus species were isolated from Exudate specimen following by Urine, Respiratory and Blood. The prevalence of MRCONS and MRSA is higher among inpatients with varying susceptibility pattern. This requires periodical surveillance and stringent infection control practices. This retrospective study was conducted to evaluate the value of the antimicrobial stewardship team (AST) combined with infectious diseases consultation on management and outcomes of Staphylococcus infections in a tertiary-care center.
