2. Prehospital shock index to assess 28-day mortality for septic shock (Abstract)

Prehospital shock index to assess 28-day mortality for septic shock In the prehospital setting, early identification of septic shock (SS) with high risk of mortality aims to initiate early treatments and to decide delivery unit (emergency department (ED) or intensive care unit (ICU)). In this context, there is a need for a prognostic measure of severity and death in order to early detect patients with a higher risk of pejorative evolution. In this study, we describe the association between (...) prehospital shock index (SI) and mortality at day 28 of patients with SS initially cared for in the prehospital setting by a mobile intensive care unit (MICU).Patients with SS cared for by a MICU between January 2016 and May 2019 were retrospectively analyzed. Using propensity score, the association between SI and mortality was assessed by Odd Ratio (OR) with 95 percent confidence interval [95 CI].One-hundred and fourteen patients among which 78 males (68%) were analysed. The mean age was 71 ± 14 years

5. The prognostic value of shock index for the outcomes of acute myocardial infarction patients: A systematic review and meta-analysis. (Full text)

The prognostic value of shock index for the outcomes of acute myocardial infarction patients: A systematic review and meta-analysis. Several studies have revealed that high shock index (SI) is a risk factor for acute myocardial infarction (AMI) patients. These studies do not give a systematic review in this issue. Therefore, we conducted a systematic review and meta-analysis to determine the effect of high SI on the prognosis of AMI patients.We did a systematic search of PubMed, Embase (...) , and the Cochrane Library, using various combinations of keywords such as "shock index," "shock-index," "acute myocardial infarction," "ST elevation myocardial infarction," "non-ST segment elevation myocardial infarction," "STEMI," "NSTEMI," "AMI," and "MI" for eligible studies published up to December 23, 2016. The 3 primary outcomes for this analysis were all-cause in-hospital mortality, short-term adverse outcomes, and long-term adverse outcomes.Database searches retrieved 226 citations.

6. Increased body mass index and adjusted mortality in ICU patients with sepsis or septic shock: a systematic review and meta-analysis. (Full text)

Increased body mass index and adjusted mortality in ICU patients with sepsis or septic shock: a systematic review and meta-analysis. At least 25 % of adults admitted to intensive care units (ICU) in the United States have an overweight, obese or morbidly obese body mass index (BMI). The effect of BMI on adjusted mortality in adults requiring ICU treatment for sepsis is unclear. We performed a systematic review of adjusted all-cause mortality for underweight, overweight, obese and morbidly obese (...) BMIs relative to normal BMI for adults admitted to the ICU with sepsis, severe sepsis, and septic shock.PubMed, the Cochrane Library, and EMBASE electronic databases were searched through November 18, 2015, without language restrictions. We included studies that reported multivariate regression analyses for all-cause mortality using standard BMI categories for adults admitted to the ICU for sepsis, severe sepsis, and septic shock.

7. Is Shock Index a Valid Predictor of Mortality in Emergency Department Patients With Hypertension, Diabetes, High Age, or Receipt of beta- or Calcium Channel Blockers? (Abstract)

Is Shock Index a Valid Predictor of Mortality in Emergency Department Patients With Hypertension, Diabetes, High Age, or Receipt of beta- or Calcium Channel Blockers? Shock index is a widely reported tool to identify patients at risk for circulatory collapse. We hypothesize that old age, diabetes, hypertension, and β- or calcium channel blockers weaken the association between shock index and mortality.This was a cohort study of all first-time emergency department (ED) visits between 1995 (...) and 2011 (n=111,019). We examined whether age 65 years or older, diabetes, hypertension, and use of β- or calcium channel blockers modified the association between shock index and 30-day mortality.The 30-day mortality was 3.0%. For all patients, with shock index less than 0.7 as reference, a shock index of 0.7 to 1 had an adjusted odds ratio (OR) of 2.9 (95% confidence interval [CI] 2.7 to 3.2) for 30-day mortality, whereas shock index greater than or equal to 1 had an OR of 10.5 (95% CI 9.3 to 11.7

8. Usefulness of the Admission Shock Index for Predicting Short-Term Outcomes in Patients With ST-Segment Elevation Myocardial Infarction (Abstract)

Usefulness of the Admission Shock Index for Predicting Short-Term Outcomes in Patients With ST-Segment Elevation Myocardial Infarction Current risk scores of ST-segment elevation myocardial infarction (STEMI) need sophisticated algorithm and were limited for bedside use. Our study aimed to evaluate the usefulness of admission shock index (SI) for predicting the short-term outcomes in patients with STEMI. Included were 7,187 consecutive patients with STEMI. The admission SI was defined (...) of admission SI for predicting 7- and 30-day all-cause mortality was 0.701 and 0.686, respectively, compared with 0.744 and 0.738 from the Thrombolysis In Myocardial Infarction risk score. In conclusion, admission SI, an easily calculated index at first contact, may be a useful predictor for short-term outcomes especially for acute phase outcomes in patients with STEMI.

12. Prognostic value of the shock index along with transthoracic echocardiography in risk stratification of patients with acute pulmonary embolism (Abstract)

Prognostic value of the shock index along with transthoracic echocardiography in risk stratification of patients with acute pulmonary embolism The initial clinical presentation and echocardiography have key roles in risk stratification of patients with acute pulmonary embolism (PE). To assess the value of shock index and echocardiographic abnormalities as predictors of in-hospital complications and mortality, echocardiographic features of 159 patients diagnosed with acute PE were reviewed (...) . A shock index > or =1, independent of echocardiographic findings, was associated with increased in-hospital mortality. Regardless of shock index, moderate to severe right ventricular (RV) hypokinesis and a ratio of RV to left ventricular (LV) end-diastolic diameter >1 was significantly associated with in-hospital mortality and demonstrated the best predictive values for short-term outcomes. The sensitivity and negative predictive value of diastolic LV impairment (E/A wave <1), RV hypokinesis, RV/LV >1
