Spinal Epidural Abscess: In Search of Reasons for an Increased Incidence

    Summary

    Background: Spinal epidural abscess (SEA) is a rare disease with a potentially devastating outcome, and a reported incidence traditionally estimated at 0.2–2 cases/10,000 hospital admissions. Since the implementation in October 2007 of a program to increase medical personnel’s awareness of SEA, we have documented a sharp increase in the incidence of SEA at our medical center

    Objectives: To investigate the cause of the increased incidence of SEA.

    Methods: All cases diagnosed with SEA during the period 1998–2010 were retrospectively reviewed. Cases diagnosed before 2007 were compared with those diagnosed thereafter.

    Results: From January 1998 to October 2007 SEA was diagnosed in 22 patients (group A), giving an annual incidence of 0.14–0.6 cases per 10,000 admissions. During the period November 2007 to April 2010, 26 additional patients were diagnosed (group B), yielding an incidence of 0.81–1.7 cases per 10,000 admissions (P < 0.01). The two groups did not differ significantly in epidemiological, clinical or laboratory characteristics, or in the causative bacteria isolated.

    Conclusions: The threefold rise in the incidence of SEA observed at a tertiary medical center in Tel Aviv since November 2007 was not explained by different host characteristics or by more virulent bacterial isolates. We suggest that heightened awareness of the clinical presentation and timely utilization of MR imaging has resulted in more cases being identified.
