Clinical Scorecard: Antibiotic-Resistant Streptococcus pneumoniae and Its Role in Acute Respiratory Infections Among Adults in the United States
At a Glance
Category
Detail
Condition
Antibiotic-nonsusceptible Streptococcus pneumoniae causing nonbacteremic pneumonia and sinusitis
Key Mechanisms
Antibiotic nonsusceptibility varies by pneumococcal serotype, affecting treatment outcomes and increasing healthcare burden
Target Population
US adults aged 18 years and older
Care Setting
Outpatient and inpatient healthcare settings
Key Highlights
An estimated 16.4% of nonbacteremic pneumococcal pneumonia and 19.0% of sinusitis cases were nonsusceptible to ≥3 antibiotic classes.
Antibiotic-nonsusceptible pneumococcal infections caused substantial outpatient visits and hospitalizations annually in US adults.
New pneumococcal conjugate vaccines (PCV15/20/21) target serotypes associated with antibiotic nonsusceptibility and may reduce disease burden.
Guideline-Based Recommendations
Diagnosis
Consider antibiotic nonsusceptibility patterns in diagnosis of pneumococcal pneumonia and sinusitis.
Use serotype distribution data to inform clinical suspicion of resistant pneumococcal strains.
Management
Incorporate antibiotic stewardship to mitigate antibiotic-nonsusceptible pneumococcal disease burden.
Use guideline-recommended antibiotics considering local resistance patterns.
Vaccinate eligible adults with PCV15, PCV20, or PCV21 to reduce infections by resistant serotypes.
Monitoring & Follow-up
Surveillance of pneumococcal serotypes and antibiotic susceptibility is essential for guiding treatment and vaccine policy.
Monitor incidence rates of nonbacteremic pneumonia and sinusitis attributable to pneumococcus.
Risks
Penicillin-nonsusceptibility is associated with increased 30-day mortality in pneumococcal infections.
Antibiotic-nonsusceptibility leads to increased healthcare utilization and costs.
Patient & Prescribing Data
US adults with nonbacteremic pneumococcal pneumonia and sinusitis
Approximately 31.2% of pneumonia and 10.5% of sinusitis cases were nonsusceptible to at least one outpatient first-line antibiotic, indicating the need for tailored antibiotic selection.
Clinical Best Practices
Employ pneumococcal conjugate vaccines (PCV15/20/21) in eligible adult populations to reduce antibiotic-nonsusceptible infections.
Apply antibiotic stewardship principles to minimize development and spread of resistance.
Use local and national surveillance data to guide empirical antibiotic therapy for pneumococcal ARIs.
Recognize the importance of serotype-specific resistance patterns in clinical decision-making.
Older age, male sex, underweight status, reduced activities of daily living, and mild consciousness disturbance were associated with postextubation pneumonia in elective surgical patients.
