A bacteria called Staphylococcus aureus, a type of staph bacteria, causes osteomyelitis. Certain chronic conditions like diabetes may increase your risk for osteomyelitis.A sample of medical records was reviewed to assess the specificity of the VO case definition. In 2002-2003, 1977 and 2036 hospital stays corresponding to 1422 and 1425 patients (median age 59 years, male:female ratio 1.5) were classified as definite (64%), probable (24%) and possible (12%) VO. The overall incidence of VO was 2.4/100,000. Incidence increased with age: 0.3/100,000 (70 years).
The main infectious agents reported were Staphylococcus spp. (38%) and Mycobacterium tuberculosis (31%). The most frequent comorbidities were septicaemia (27%) and endocarditis (9%). Three percent of patients died. A review of 90 medical records confirmed the diagnosis of VO in 94% of cases. Using a hospital database and a specific case definition, nationwide surveillance of VO is possible. chronic osteomyelitis arising from a contiguous soft-tissue focus, particularly in patients with diabetes, empiric treatment must be effective against anaerobic organisms in addition to gram-positive and gram-negative aerobes. Ampicillin/sulbactam 3 g IV q 6 h or piperacillin/tazobactam 3.375 g IV q 6 h is commonly used; vancomycin 1 g IV q 12 h is added when infection is severe or MRSA is prevalent. Antibiotics must be given parenterally for 4 to 8 wk and tailored to results of appropriate cultures.
