The purpose of this study was to compare patient factors and outcomes in conservatively and surgically treated patients with spinal epidural abscess (SEA). This was a single-center retrospective review of adult patients treated for SEA of the lumbar spine. Primary treatment outcome was readmission for recurrent abscess. Sixty-one patients met inclusion criteria: 59% male, mean age 56.9 years, and body mass index 30.8 kg/m2. Initially 47.5% of patients were treated with conservative measures and 52.5% were treated with surgery. In the conservative group, 31.0% failed treatment and underwent delayed surgery; 26.2% of the overall cohort was readmitted for SEA. Readmitted patients had a greater incidence of history of methicillin-resistant Staphylococcus aureus (p = .048), recurrent infections (p = .008), and recent sepsis and bacteremia (p = .005). Nearly one-third of patients failed initial conservative treatment and needed delayed surgery; however, no significant differences were found between the two treatment groups. Patients with a past history of infections may require more aggressive treatment and closer follow-up, because they are at higher risk for recurrence and readmission.
