Serial measurements of SIRS and SEP scores to identify unique phenotypes of sepsis
AbstractUsing scoring systems in discreet microbiologic cohorts in a serial fashion to identify unique phenotypes of sepsis remains unknown. Single-center, retrospective study that screened adults who triggered the hospital ’s SIRS (systemic inflammatory response syndrome) based sepsis alert into culture positive (Cx +) and culture negative (Cx−) groups. Subgroups were based on the location where the SIRS alert fired. SIRS scores and a novel score called SEP were calculated att = 0 and at 3, 6, 12, and 24 h before and aftert = 0. Primary outcome was a difference in SIRS/SEP scores in Cx + or Cx− groups over time. Secondary outcomes were differences in total SIRS/SEP scores and the components constituting SIRS/SEP scores at various locations over time. The study contained 7955 patients who met inclusion criteria. Cx + and Cx− groups had increases in SIRS/SEP scores and at similar rates starting 6 hours beforet = 0. Both culture groups had decreasing SIRS/SEP scores, at varying gradients compared to the change in SIRS/SEP scores seen prior tot = 0. This pattern in SIRS/SEP scores before and aftert = 0 was consistent in all location subgroups. Statistically significant differences were seen in the overall SIRS/SEP scores for Cx + and Cx− groups at hours 6, 12, and 24 aftert = 0, in the ED group att = 24 h aftert = 0, the floor group att = 0 h, and in the step-down group att = 3 h aftert = 0 ...
