A40.1 Sepsis due to streptococcus, group B

Name of the Condition

• Sepsis due to streptococcus, group B

Summary

Sepsis due to streptococcus, group B is a severe, life-threatening condition resulting from a systemic infection caused by group B streptococcal bacteria. It involves the presence of these bacteria in the bloodstream, triggering a widespread inflammatory response that can lead to organ dysfunction and septic shock. Prompt medical intervention is critical to manage the infection and prevent complications.

Causes

Sepsis due to streptococcus, group B is caused by infection with Streptococcus agalactiae, a type of group B streptococcus. The bacteria typically enter the bloodstream through breaks in the skin, respiratory tract, or other sites of infection, such as cellulitis, urinary tract infections, or surgical wounds. This invasion triggers a systemic inflammatory response, leading to sepsis.

Risk Factors

• Recent group B streptococcal infection (e.g., skin infections, urinary tract infections)
• Weakened immune system (e.g., HIV, immunosuppressive therapy)
• Chronic conditions (e.g., diabetes, liver disease)
• Invasive procedures or surgeries
• Advanced age or infancy
• Pregnancy (neonatal risk)

Symptoms

• High fever or hypothermia
• Rapid heart rate and breathing
• Low blood pressure (septic shock)
• Confusion or altered mental status
• Chills and sweating
• Skin rash or discoloration
• Organ dysfunction (e.g., kidney, liver)

Diagnosis

Diagnosis involves clinical evaluation, blood cultures to identify group B streptococcal bacteria, and assessment of organ function. Additional tests (e.g., imaging, biomarkers) may be used to detect infection sources or evaluate organ involvement.

Treatment Options

• Antibiotics: Intravenous antibiotics targeting group B streptococcus are administered promptly.
• Supportive Care: Fluid resuscitation, vasopressors for hypotension, and organ support (e.g., mechanical ventilation) as needed.
• Source Control: Surgical or other interventions to remove or drain the infection source.

Prognosis and Follow-Up

Prognosis depends on the severity of organ dysfunction, timeliness of treatment, and underlying health. Survivors may require ongoing monitoring for complications. Follow-up care focuses on managing residual organ damage and preventing recurrence.

Complications

• Septic shock
• Multiple organ failure
• Disseminated intravascular coagulation (DIC)
• Acute respiratory distress syndrome (ARDS)
• Long-term organ dysfunction

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk.
• Promptly treat skin or soft tissue infections.
• For high-risk groups (e.g., pregnant individuals), follow recommended screening and preventive measures.
• Avoid unnecessary invasive procedures when possible.

When to Seek Professional Help

Seek immediate medical attention for symptoms of sepsis, including fever, rapid breathing, confusion, or low blood pressure, especially if there is a known or suspected infection.

Tips for Medical Coders

Document the presence of group B streptococcal infection and sepsis to support code assignment. Ensure clinical documentation specifies the bacterial group and systemic infection to align with the code's definition.
