Spondylodiscitis is a rare but serious infection of the spine. Recognised methods of treatment include immobilisation and systemic antibiotics. However, available data for specific and recommendations for continuing treatment are also rare. The aim of the present study is the optimisation of the therapy of spondylodiscitis using a clinical pathway that depends on a classification of spondylodiscitis. From 1 October 1998 to 31 December 2013, a classification of the severity of spondylodiscitis was established, including specific treatment recommendations. As part of the re-evaluation, the classification of severity was adapted. On this basis, electronically based clinical pathways were developed. A total of 296 cases were included. With a steadily increasing number of treatments, the mean age of the patients increased to 67.3 years. In 34.3% of these patients, spondylodiscitis developed spontaneously and 68.6% of patients did not receive treatment until the diagnosis. In the context of the specific treatment, pain intensity decreased from 6.0 to 3.1 NRS (numeric rating scale). The inflammatory values (CRP) decreased from 119.2 to 46.7 mg/dl. The time from the onset of symptoms to the surgical treatment was almost 65.6 days and has not changed significantly. Nevertheless, the time from admission to surgical treatment could be reduced to less than 3 days. The classification of patients into 3 degrees of severity of spondylodiscitis (SSC) depends on the SponDT: spondylodiscitis diagnosis and treatment. The SponDT describes vertebral destruction and the current neurological status. The severity-adapted therapy was mapped electronically and includes specific surgical care, systemic antibiotic therapy and physical therapy.
