It is important for clinicians to recognize the contribution of toxic shock syndrome (TSS) to the overall burden of pediatric septic shock because the clinical features, optimal therapy and prognosis differ from non-TSS septic shock.
We analyzed cases of pediatric septic shock reported to the Pediatric Health Information Systems database between 2009 and 2013 to define the clinical and demographic characteristics of pediatric TSS in the United States. Using a validated International Classification of Diseases, 9th revision, coding strategy, we identified patients with infectious shock among inpatients age 1–18 years and classified cases of staphylococcal and streptococcal TSS for comparison with non-TSS cases.
Of 8,226 cases of pediatric septic shock, 909 (11.1%) were classified as TSS and 562 (6.8%) were possible TSS cases. Staphylococcal TSS represented the majority (83%) of TSS cases and occurred more commonly in females and at an older age. Compared with non-TSS septic shock, TSS had significantly lower fatality rates, disease severity and length of hospital stay and was present more often at the time of admission (P < 0.001 for each). Streptococcal TSS was associated with poorer outcomes than staphylococcal TSS. Treatment for TSS differed from non-TSS septic shock in use of more clindamycin, vancomycin and Intravenous Immunoglobulin and less need for vasopressors.
Results demonstrate a significant contribution of TSS to the burden of pediatric septic shock in the United States. The findings emphasize the importance of inclusion of TSS diagnostic and therapeutic considerations in sepsis treatment protocols for children.
