outcomes in sepsis, either as a replacement or a complement. For example, a retrospective cohort study of patients arriving at emergency care units compared the value of using end-tidal carbon dioxide with the qSOFA screening tool and concluded that it allowed for a slightly better prediction of mortality due to severe sepsis. 11 Another study of patients receiving intensive care showed that hypothermia can complement the role of qSOFA in the identification of patients at risk of suffering multiple organ dysfunction or death. 12 Moreover, a simplified version of qSOFA using clinical parameters that are easy to obtain in the hospital showed a performance level similar to that of SOFA. 13 Despite these encouraging data, the search for simpler scoring systems with higher sensitivity continues. Institutions must continuously strive to deliver timely and adequate care, which might involve easy- to-apply and non-invasive screening approaches prior to hospital admission References 1 Stevenson EK et al.

However, well-designed and robust studies are needed to confirm the sensitivity and specificity of screening tools in the pre-hospital setting. Early warning scores for sepsis and septic shock Early warning systems have been developed to stratify patients according to risk and alert clinicians when a patient’s condition worsens, with favourable but somehow heterogeneous results. The National Early Warning Score (NEWS) has showed to be a good predictor of mortality and transfer to the intensive care unit for patients admitted to the emergency department and those with respiratory distress, whereas the Mortality in Emergency Department Sepsis (MEDS) score performed better for patients with an infection or sepsis. 14 The NEWS also presented superior sensitivity compared with qSOFA under some circumstances. 4 At the triage stage, the implementation of screening tools based on the presence of signs such as altered mental status may also allow for an earlier identification of patients at risk and reduce the time to administration of intravenous fluid and antibiotics in emergency departments. 15 An electronic alert system was developed to detect severe sepsis and septic shock in patients admitted to the emergency department of a tertiary care clinical unit in Saudi Arabia, through the assessment of clinical and analytical parameters taking into account organ failure dysfunction criteria. When compared with conventional identification of patients by physicians specialised in emergency medicine or critical care, this system showed high sensitivity Conclusions Compared with controls, sepsis survivors show higher mortality rates after discharge and increased incidence of cognitive impairment as well as overall physical disability and impaired pulmonary function. 19,20 Sepsis thus requires prompt intervention in order to improve patient outcomes in the long-term, but quality improvement initiatives may be particularly difficult to implement in countries with fewer resources and limited infrastructure, hence the importance of early recognition. 21 It must not be forgotten that sepsis does not only occur in the intensive care setting; therefore institutions must continuously strive to deliver timely and adequate care, which might involve easy-to-apply and non-invasive screening approaches prior to hospital admission. Failure by health care professionals to fully adhere to guidelines and inappropriate use of antimicrobial agents leading to resistance are unfortunately common, even in well-equipped facilities. In the absence of an optimal biochemical marker and laboratory test to guide the diagnosis of this critical condition in clinical practice, continuing education and protocol testing are crucial elements in early sepsis diagnosis and stratification of severity. Future research studies will certainly provide solid and robust scientific evidence on the accuracy of the currently available, and to be developed, tools for early sepsis screening. 2001;345:368–77. 6 Gauer RL.
