Management of Adult Sepsis in Resource-Limited Settings: A Global Delphi-Based Consensus

Introduction: This summary presents key points from a recent expert consensus on managing adult sepsis under limited-resource conditions, where patients may lack access to an ICU bed, advanced monitoring technologies, or sufficient staffing. The statements were developed through a Delphi process involving an international panel of clinicians, aiming to complement existing sepsis guidelines by focusing on pragmatic approaches and context-specific adaptations. These consensus statements address unique challenges such as limited diagnostic tests, alternative strategies for hemodynamic monitoring, and management of sepsis in areas with tropical infections.

Key Recommendations:

1. Location of Care and Transfer
   • When an ICU bed is unavailable, care can be provided in a non-ICU setting if minimum monitoring (neurological status, blood pressure, peripheral perfusion) is ensured.
   • Before transferring a patient, ensure airway patency, initiate intravenous fluids and antimicrobials, and maintain safe transport conditions.
   • Incorporate telemedicine or phone consultation with critical care specialists whenever feasible.
2. Diagnostic Considerations
   • Employ screening tools (e.g., qSOFA) in areas with limited resources, acknowledging its diagnostic constraints.
   • Use clinical parameters like altered mental state, capillary refill time (CRT), and urine output to gauge tissue perfusion when lactate measurement is unavailable.
   • Insert an indwelling urinary catheter in septic shock to monitor urine output accurately, balancing infection risks against close monitoring needs.
3. Hemodynamic Management
   • Rely on clinical indicators (CRT, urine output) to guide fluid resuscitation when serum lactate is not accessible.
   • Use fluid responsiveness tests (e.g., passive leg raising, pulse pressure variation) if advanced hemodynamic monitoring is impractical.
   • Consider balanced solutions such as Ringer’s lactate or Hartmann’s solution for fluid resuscitation.
   • Recognize that patients with tropical infections (e.g., malaria, dengue) may require cautious fluid volumes to avoid overload.
   • Initiate epinephrine if norepinephrine or vasopressin is unavailable, and use vasopressors through peripheral lines if central access cannot be established.
4. Antimicrobial Therapy
   • Administer antibiotics without delay (ideally within one hour) in suspected sepsis or septic shock.
   • In severe infections of parasitic origin (e.g., malaria), start antiparasitic agents promptly.
   • In settings where laboratory investigations are limited, begin broad-spectrum antimicrobial coverage when infection cannot be ruled out.
   • De-escalate or discontinue therapy based on clinical improvement, declining white blood cell counts, and adequate source control.
5. Respiratory Support
   • For acute hypoxemic respiratory failure in septic patients, noninvasive ventilation (NIV) can be used if high-flow nasal oxygen is not available, provided close monitoring for potential failure is ensured.

Conclusion: These consensus-based statements offer practical guidance for clinicians treating sepsis in resource-limited environments. By adapting globally accepted recommendations and incorporating alternative strategies—such as clinical markers of perfusion, use of peripheral vasopressors, and prioritizing immediate antimicrobial therapy—these principles aim to improve patient outcomes where healthcare resources are scarce. Further research and context-specific adaptations will be essential to address remaining uncertainties and refine these expert recommendations.
