Objectives :

Ø             To determine the most common bacterial resistance trait

a retrospective chart review study including all patients undergoing surgical procedures  from January 2019 to January of king Abdullah medical city hospital

Results :

During the full study duration, 100 SSIs were culture-confirmed with no RIs reported. Specimens used for culture were variable; most of them were wound swabs (75%), followed by drain fluid (18%), peritoneal fluid (2%), aspiration fluid (2%), biopsy tissue (1%), CSF (1%), and tissue/biopsy (1%). For bacterial strains detected, mixed bacterial growth was the most common (23%), followed by E-coli (19%), Klebsiella Pneumoniae (16%), Staphylococcus aureus (9%), Methicillin-resistant Staphylococcus aureus (MRSA) (6%), Coagulase-negative staphylococci (CoNS) (5%), Candida albicans (3%), Enterococcus faecalis (3%), and Enterobacter aerogenes (2%).

The peak of infections’ number reached on October 2019 and December 2019 with 12 cases each. This was followed by August (11 cases), February (9 cases), March (9 cases), November (8 cases), and April (7 cases) 2019 . Mixed bacterial infection was the only steady finding of cultures taking over all months. Wound swab was the most common specimen type tested overall months and was the only one in January and April 2019 .


Post-operative SSIs are common in surgical practice and SAP may not be successful in all cases. Availing the most recommended SAP antibiotics, surveilling SAP practices, and adopting educational programs are required. Moreover, targeted hospital infection control systems and wound surveillance programs are highly recommended for the effective reduction of SSIs to an acceptable rate.
