Prehospital Shock Precautions on Triage (PSPoT) score to assess in-hospital mortality for septic shock

Context: In the prehospital setting, early identification of septic shock (SS) with high risk of poor outcome is a daily issue. There is a need for a simple tool aiming to early assess outcome in order to decide delivery unit (emergency department (ED) or intensive care unit (ICU)). In France, prehospital emergencies are managed by the Service d'Aide M & eacute;dicale d'Urgence (SAMU). The SAMU physician decides the destination ward either to the ICU or to the ED after on scene severity assessment. We report the association between The Prehospital Shock Precautions on Triage (PSPoT) score, and in-hospital mortality of SS patients initially cared for in the prehospital setting by a mobile ICU (MICU). Methods: SS patients cared for by MICU were prospectively included between February 2017 and July 2019. The PSPoT score was established by adding shock index>1 and criterion based on past medical history: age >65 years and at least 1 previous comorbidity (chronic cardiac failure, chronic renal failure, chronic obstructive pulmonary disease, previous or actual history of cancer, institutionalization, hospitalisation within previous 3 months. A threshold of >_2, was arbitrarily chosen for clinical relevance and usefulness in clinical practice. Results: One-hundred and sixty-nine with a median age of 72 [20-93] years were analysed. SS origin was mainly pulmonary (54%), abdominal (19%) and urinary (15%). The median PSPoT score was 2 [1-2]. PSPoT score and PSPoT score >_ 2 were associated with in-hospital mortality: OR = 1.24 [0.77-2.05] and OR = 2.19 [1.09-4.59] respectively. Conclusion: We report an association between PSPoT score, and in-hospital mortality of SS patients cared for by a MICU. A PSPoT score >_ 2 early identifies poorer outcome. (c) 2020 Elsevier Inc.
