Abstract
AbstractObjectiveTo evaluate the use of a modified Sepsis‐3 (mSepsis‐3) definition compared to the currently used modified Sepsis‐2 (mSepsis‐2) definition to determine whether the mSepsis‐2 or mSepsis‐3 stratifications were able to identify populations of dogs ultimately more likely to die from canine parvovirus (CPV) infection.DesignRetrospective, January 2009 to March 2020.SettingA private, small animal, urban, referral emergency and specialty hospital.AnimalsFifty‐nine client‐owned dogs hospitalized for treatment of CPV.InterventionsNone.Measurements and Main ResultsDogs were divided into mSepsis‐2 and mSepsis‐3 categories based on the highest level of illness severity reached during hospitalization. Greater illness severity based on mSepsis‐2 criteria (ie, sepsis, severe sepsis, septic shock) was associated with an increase in average length of stay (P < 0.001), increase in average cost of stay (P < 0.01), and presence of leukopenia (P < 0.05). An increase in illness severity within the mSepsis‐2 criteria was not associated with hyperlactatemia (P = 0.29), presence of neutropenia (P = 0.12), or mortality (P = 0.35). Greater illness severity based on mSepsis‐3 criteria (ie, infection only, sepsis, septic shock) was associated with an increase in mortality (P < 0.05), increase in average length of stay (P < 0.001), increase in average cost of stay (P < 0.01), presence of leukopenia (P < 0.01), and presence of neutropenia (P < 0.05). The mSepsis‐3 criteria were not associated with the presence of hyperlactatemia (P = 0.68). There was no significant difference between survivors and nonsurvivors in the presence of leukopenia (P = 0.19), neutropenia (P = 0.67), or hyperlactatemia (P = 0.58).ConclusionsThe mSepsis‐3 diagnostic criteria appear to better identify dogs with CPV at higher risk for mortality compared to the mSepsis‐2 criteria.
