Population-Based Analysis of Incidence and Mortality of Septic Shock

Condition(s) studied

Investigational drug(s) / intervention(s)

Person-level linkage of the database looking for relationship with septic shock survival and comorbidities, previous intake of medication, and previous dependence on health services.: A descriptive analysis of the baseline demographics, risk factors, health status, comorbidities, frailty, and previous dependence on health services of all patients admitted with septic shock to hospitals in the region will be carried out. The overall data of patients admitted to hospitals will be analysed. The survival data of patients will be compared with their previous individual drug consumption and inhospital survival to septic shock. In addition, drug dependence and dependence on health services of survivors will be studied in comparison with their situation prior to sepsis. The objective is to establish the Registry of Administrative Data Automatically Recorded for Septic Shock (RADAR-Septic Shock), leveraging administrative data to characterize septic shock incidence, describe patient profiles, identify population-specific healthcare needs, and provide benchmark values for performance assessment in Catalonia's public health system.

Study summary

RADAR-Septic Shock is a population-based observational study in Catalonia (Spain) that will identify all hospital discharges with septic shock between 2018 and 2023 using an audited population-based registry. The project will quantify incidence, describe patient characteristics and resource use, and compare risk-adjusted in-hospital mortality across hospitals to support quality improvement. Cases are defined by ICD-10 codes for septic shock (R65.21) and post-procedural septic shock (T81.12XA). In preliminary cohort counts, \>31,000 episodes were identified across 2018-2023; in 2023 the incidence was \~78 per 100,000 inhabitants with an overall in-hospital mortality of \~33%, higher in hospital-acquired than community-acquired episodes

Eligibility

Primary outcome measure(s)

• Death due to septic shock — From date of hospital admission until the date of hospital discharge, assessed up to 12 months
  Inhospital death after an episode of septic shock requiring hospital or ICU admission
