OBJECTIVE: The aim of this study was to identify factors associated with the surgical treatment of Thai patients with septic arthritis.
METHODS: This cohort study used a university hospital database in Thailand to identify 450 adult patients with confirmed septic arthritis. Data related to baseline characteristics, clinical and laboratory findings, treatment, and outcomes were collected. A multivariate analysis identified the factors related to surgical treatment.
RESULTS: The patients had a mean age (±SD) of 53.6 (±17.8) years, and 51% were male. Surgical drainage was performed on 332 patients (74%). The factors identifed as relating to the need for surgical drainage included preexisting joint disease (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.3-4.9), hip involvement (OR, 36.3; 95% CI, 4.1-320.5), abscess formation (OR, 5.6; 95% CI, 1.1-27.1), osteomyelitis (OR, 4; 95% CI, 1.1-14.9), and positive synovial fluid culture (OR, 3.8; 95% CI, 2-7.2). In contrast, patients who were treated with steroids (OR, 0.2; 95% CI, 0.1-0.4) or had septic shock (OR, 0.31; 95% CI, 0.13-0.83) were less likely to undergo surgery. This model correctly predicted 35% of cases. Patients treated with surgical drainage had a significant longer length of stay (median [interquartile range], 21 [11-34] days vs 14 [7-24] days; p < 0.0001) and were less likely to achieve complete recovery (26% vs 53%, p < 0.0001). However, the mortality rate was lower (2.4% vs 10.2%).
CONCLUSIONS: Patients with septic arthritis who had underlying joint disease, hip involvement, abscess formation, osteomyelitis, and organisms in their synovial fluid were more likely to undergo surgical intervention with a significantly prolonged length of stay but had a lower mortality rate.
