Introduction@#Septic arthritis is an infection of the joint. Considered a medical emergency, it requires prompt diagnosis and treatment. Local data on the clinical profile of septic arthritis patients in the Philippines are still limited. Therefore, this study aims to determine the clinical characteristics and outcomes of patients with septic arthritis in the local setting.@*Objective@#To determine the clinical profile and outcome of adult Filipino patients with septic arthritis admitted at a tertiary hospital. @*Methodology@#This is a retrospective descriptive study of the medical records of patients with septic arthritis admitted at Chong Hua Hospital, Cebu City, from January 2012 to December 2019.@*Results@#Fifty- seven patients were included in this study. Sixty-four percent were males. Forty-three percent were between the ages of 45 to 64 years old. Diabetes mellitus (49.12%) was identified as the most common comorbidity. 94% of patients presented with monoarthritis, with the knee being the most commonly involved joint (73%). 85% of patients presented with joint pain and swelling. Gram-negative bacilli were the most common pathogen isolated at 31.5%. In addition, 87% of patients had synovial fluid white blood cell counts of more than 50,000/uL. Ceftriaxone was the most commonly used empiric antibiotic (31.5%). Based on sensitivity results, empiric antibiotic treatment was adequate in 66.67% of the cases. 64% of patients underwent surgical intervention in addition to antibiotic therapy.@*Conclusion@#This study highlights the unique characteristics of septic arthritis in this population, such as its prevalence in middle-aged patients and the isolation of gram-negative bacilli as the most common isolate. This study showed that the majority of patients were male, with monoarthritis as the most common presentation. Half of the studied population had diabetes mellitus. High clinical suspicion and awareness of risk factors should be emphasized so that timely and adequate treatment may be provided.
