FeverPAIN Score – Strep Throat Score & Antibiotic Risk Assessment
Introduction
The FeverPAIN Score – Strep Throat Score & Antibiotic Risk Assessment is a clinical decision support tool used to estimate the likelihood of Group A Streptococcus (GAS) infection in patients with an acute sore throat. Developed and validated in UK primary care, the FeverPAIN score helps healthcare professionals determine whether antibiotics are likely to be beneficial while supporting responsible antimicrobial stewardship.
This calculator uses five simple clinical features to generate a FeverPAIN score ranging from 0 to 5, helping guide treatment decisions according to NICE recommendations.
What Is the FeverPAIN Score?
The FeverPAIN score is a validated clinical prediction rule designed to estimate the probability of streptococcal pharyngitis in patients presenting with acute sore throat.
Each of the following clinical features scores 1 point:
- Fever during the previous 24 hours
- Purulent tonsils (pus on the tonsils)
- Rapid attendance (symptoms for 3 days or less)
- Severely inflamed tonsils
- No cough or coryza (runny nose)
The total score ranges from 0 to 5.
Why Use the FeverPAIN Score?
The FeverPAIN score helps clinicians:
- Assess the likelihood of bacterial (Group A Streptococcal) infection
- Reduce unnecessary antibiotic prescribing
- Support antimicrobial stewardship
- Guide delayed or immediate antibiotic prescribing
- Improve evidence-based clinical decision-making
- Standardise sore throat assessment in primary care

FeverPAIN Score Interpretation
| Score | Clinical Interpretation | Suggested Management |
|---|---|---|
| 0–1 | Low likelihood of streptococcal infection | No antibiotics; provide self-care advice |
| 2–3 | Intermediate risk | Consider a delayed antibiotic prescription if symptoms worsen or do not improve |
| 4–5 | High likelihood of streptococcal infection | Consider immediate antibiotics if clinically appropriate |
Clinical judgment should always be used alongside the score.
When Should the FeverPAIN Score Be Used?
The FeverPAIN score is intended for patients with:
- Acute sore throat
- Suspected tonsillitis
- Pharyngitis
- Upper respiratory tract infection with throat pain
It is primarily used in primary care, urgent care, and community healthcare settings.
Limitations
The FeverPAIN score should not be used as the sole basis for treatment decisions in patients with:
- Airway compromise
- Suspected peritonsillar abscess (quinsy)
- Severe systemic illness
- Immunocompromised conditions
- Recurrent tonsillitis requiring specialist assessment
- Children where alternative diagnoses are suspected
Clinical assessment remains essential.
Symptoms That Require Urgent Medical Attention
Seek immediate medical care if a patient develops:
- Difficulty breathing
- Difficulty swallowing saliva
- Severe neck swelling
- Persistent high fever
- Confusion
- Dehydration
- Inability to open the mouth (trismus)
Frequently Asked Questions
What does the FeverPAIN score measure?
It estimates the likelihood that an acute sore throat is caused by Group A Streptococcus, helping guide antibiotic prescribing decisions.
Is the FeverPAIN score better than the Centor score?
Both scoring systems are validated clinical tools. The FeverPAIN score was developed and validated in UK primary care and is recommended by NICE for assessing acute sore throat.
Can this calculator diagnose strep throat?
No. The FeverPAIN score estimates the probability of streptococcal infection but does not confirm the diagnosis. Clinical assessment and, when appropriate, microbiological testing may still be required.
Should everyone with a high score receive antibiotics?
Not necessarily. Antibiotic prescribing should be based on the FeverPAIN score together with the patient’s symptoms, examination findings, medical history, and clinical judgment
