Prognosis
General
- Australia/New Zealand Study of Severe Sepsis and Septic Shock Mortality Rates (JAMA, 2014) [MEDLINE]
- From 2000 to 2012, there was a Decrease in the Absolute Sepsis Mortality Rate from 35.0% (95% CI, 33.2%-36.8%; 949/2708) to 18.4% (95% CI, 17.8%-19.0%; 2300/12,512; P <0.001)
- Systematic Review of the Global Incidence and Mortality of Sepsis (Am J Respir Crit Care Med, 2016) [MEDLINE]
- In Articles Restricted to the Last 10 Years, Incidence Rate was 437/100k for Sepsis and 270/100k for Severe Sepsis
- In Articles Restricted to the Last 10 Years, Hospital Mortality Rate was 17% for Sepsis and 26% for Severe Sepsis
- Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3: Society of Critical Care Medicine and European Society of Intensive Care Medicine) (JAMA, 2016) [MEDLINE]
- Sepsis Mortality Rate: 10%
- Septic Shock Mortality Rate: >40%
Sepsis Mortality Rate by Hospital Type
Clinical Data
- Retrospective National Cohort Study (of Medicare Fee-for-Service Beneficiaries, ≥66 y/o) Admitted with Sepsis to an Intensive Care Unit ( JAMA Netw Open, 2024) [MEDLINE]: n= 2,551,743 (666 safety-net hospitals and 1924 non-safety-net hospitals)
- Admission to Safety-Net Hospitals was Associated with an Increased In-Hospital Mortality Rate (Odds Ratio 1.09; 95% CI: 1.06-1.13) But Not an Increased 30-Day Mortality Rate (Odds Ratio 1.01; 95% CI: 0.99-1.04)
- Admission to Safety-Net Hospitals was Associated with Decreased Do Not Resuscitate (DNR) Rates (Odds Ratio 0.86; 95% CI: 0.81-0.91), Decreased Palliative Care Delivery Rates (Odds Ratio 0.66; 95% CI: 0.60-0.73), and Decreased Hospice Discharge (Odds Ratio 0.82; 95% CI: 0.78-0.87), But Not with Discharge to Post-Acute Facilities (Odds Ratio 0.98; 95% CI: 0.95-1.01)
- Differences in In-Hospital Mortality May Partially Be Explained by Greater Use of Hospice at Non-Safety-Net Hospitals, Which Shifts Attribution of Death from the Index Hospitalization to Hospice

Recommendations (Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock 2021) (Crit Care Med, 2021) [MEDLINE]
- For Adult Survivors of Sepsis/Septic Shock and Their Families, Referral to Peer Support Groups is Recommended (Weak Recommendation, Very Low Quality of Evidence)
- For Adults with Sepsis/Septic Shock and Their Families, Written/Verbal Sepsis Education (Diagnosis, Treatment, and Post-Intensive Care Unit/Post-Sepsis Syndrome) Prior to Hospital Discharge and in the Follow-Up Setting is Recommended (Weak, very low quality of evidence)
- For Adults with Sepsis/Septic Shock and Their Families, Clinical Team Should Provide the Opportunity to Participate in Shared Decision Making in Post-Intensive Care Unit and Hospital Discharge Planning to Ensure Discharge Plans are Acceptable and Feasible (Best Practice)
- For Adults with Sepsis/Septic Shock and Their Families, Use of a Critical Care Transition Program on Transfer to the Floor is Recommended (Weak, very low quality of evidence)
- For Adults with Sepsis/Septic Shock, Reconciling Medications at Both Intensive Care Unit and Hospital Discharge is Recommended (Best Practice)
- For Adults with Sepsis/Septic Shock and Their Families, Including Information About the Intensive Care Unit Stay, Sepsis and Related Diagnoses, Treatments, and Common Impairments After Sepsis in the Written and Verbal Hospital Discharge Summary is Recommended (Best Practice)
- For Adults with Sepsis/Septic Shock Who Have Developed New Impairments, Hospital Discharge Plans Should Include Follow-Up with Clinicians Able to Support and Manage New and Long-Term Sequelae (Best Practice)
- For Adults with Sepsis/Septic Shock and Their Families, There is Insufficient Evidence to Make a Recommendation Regarding Early Post-Hospital Discharge Follow-Up, as Compared with Routine Post-Hospital Discharge Follow-Up (No Recommendation)
- For Adults with Sepsis/Septic Shock, There is Insufficient Evidence to Make a Recommendation Regarding Early Cognitive Therapy (No Recommendation)
- For Adult Survivors of Sepsis/Septic Shock, Assessment and Follow-Up for Physical, Cognitive, and Emotional Problems After Hospital Discharge is Recommended (Best Practice)
- For Adult Survivors of Sepsis/Septic Shock, Referral to a Post-Critical Illness Follow-Up Program is Recommended, if Available (Weak Recommendation, Very Low Quality of Evidence)
- For Adult Survivors of Sepsis/Septic Shock Receiving Mechanical Ventilation for >48 hrs or an Intensive Care Unit Stay of >72 hrs, Referral to a Post-Hospital Rehabilitation Program is Recommended (Weak Recommendation, Very Low Quality of Evidence)
