NICE sore throat guideline: antimicrobial prescribing

NICE has released its new guidelines for managing acute sore throat and antimicrobial prescribing.All people with acute sore throat should be aware that acute sore throat (including pharyngitis and tonsillitis) is self‑limiting and often triggered by a viral infection of the upper respiratory tract.Its symptoms can last for around 1 week, but most people will get better within this time without antibiotics, regardless of cause (bacteria or virus).It is therefore important that clinicians should assess and manage children under 5 who present with fever as outlined in the NICE guideline on fever in under 5s.They may use FeverPAIN or Centor criteria to identify people who are more likely to benefit from an antibiotic and manage in line with recommendations below.If at any time symptoms worsen rapidly or significantly alternative diagnoses such as scarlet fever or glandular fever should be considered.

Key Recommendations:

People who are unlikely to benefit from an antibiotic (FeverPAIN score of 0 or 1, or Centor score of 0, 1 or 2):

• Do not offer an antibiotic prescription


• As well as the general advice mentioned above, give advice about:
  
  
  
  • an antibiotic not being needed
  
  
  • seeking medical help if symptoms worsen rapidly or significantly, do not start to improve after 1 week, or the person becomes systemically very unwell
  
  
  
  


• See the evidence and committee discussion on no antibiotic.

People who may be more likely to benefit from an antibiotic (FeverPAIN score of 2 or 3)

• Consider no antibiotic prescription with advice or a back-up antibiotic prescription, taking account of:
  
  
  
  • evidence that antibiotics make little difference to how long symptoms last (on average, they shorten symptoms by about 16 hours)
  
  
  • evidence that most people feel better after 1 week, with or without antibiotics
  
  
  • the unlikely event of complications if antibiotics are withheld
  
  
  • possible adverse effects, particularly diarrhoea and nausea
  
  
  
  


• When a back-up antibiotic prescription is given, as well as the general advice in recommendation , give advice about:
  
  
  
  • an antibiotic not being needed immediately
  
  
  • using the back-up prescription if symptoms do not start to improve within 3 to 5 days or if they worsen rapidly or significantly at any time
  
  
  • seeking medical help if symptoms worsen rapidly or significantly or the person becomes systemically very unwell
  
  
  
  

People who are most likely to benefit from an antibiotic (FeverPAIN score of 4 or 5, or Centor scoreof 3 or 4)

• Consider an immediate antibiotic prescription (see recommendation for choice of antibiotic), or a back-up antibiotic prescription with advice (see recommendation ), taking account of:
  
  
  
  • the unlikely event of complications if antibiotics are withheld
  
  
  • possible adverse effects, particularly diarrhoea and nausea
  
  
  
  


• When an immediate antibiotic prescription is given, as well as the general advice in recommendation , give advice about seeking medical help if symptoms worsen rapidly or significantly or the person becomes systemically very unwell


• See the evidence and committee discussion on back-up antibiotics and choice of antibiotic

People who are systemically very unwell, have symptoms and signs of a more serious illness or condition, or are at high-risk of complications

• Offer an immediate antibiotic prescription (see recommendation for choice of antibiotic) with advice or further appropriate investigation and management


• Refer people to hospital if they have acute sore throat associated with any of the following:
  
  
  
  • a severe systemic infection (see the NICE guideline on sepsis)
  
  
  • severe suppurative complications (such as quinsy [peri-tonsillar abscess] or cellulitis, parapharyngeal abscess or retropharyngeal abscess or Lemierre syndrome)
  
  
  
  


• See the evidence and committee discussion on choice of antibiotic

Self-care

All people with acute sore throat

• Consider paracetamol for pain or fever, or if preferred and suitable, ibuprofen.


• Advise about the adequate intake of fluids.


• Explain that some adults may wish to try medicated lozenges containing either a local anaesthetic, a non-steroidal anti-inflammatory drug (NSAID) or an antiseptic. However, they may only help to reduce pain by a small amount.


• Be aware that no evidence was found on non-medicated lozenges, mouthwashes, or local anaesthetic mouth spray used on its own.


• See the evidence and committee discussion on self-care

Choice of antibiotic

• When prescribing an antibiotic for acute sore throat:
  
  
  
  • follow table 1 for adults aged 18 years and over
  
  
  • follow table 2 for children and young people under 18 years
  
  
  
  

 

• See the evidence and committee discussion on choice of antibiotic and antibiotic course length

Terms used in the guideline

People with a sore throat caused by streptococcal bacteria are more likely to benefit from antibiotics. FeverPAIN or Centor criteria are clinical scoring tools that can help to identify the people in whom this is more likely

FeverPAIN criteria

• F ever (during previous 24 hours)


• P urulence (pus on tonsils)


• A ttend rapidly (within 3 days after onset of symptoms)


• Severely I nflamed tonsils


• N o cough or coryza (inflammation of mucus membranes in the nose)

Each of the FeverPAIN criteria score 1 point (maximum score of 5). Higher scores suggest more severe symptoms and likely bacterial (streptococcal) cause. A score of 0 or 1 is thought to be associated with a 13 to 18% likelihood of isolating streptococcus. A score of 2 or 3 is thought to be associated with a 34 to 40% likelihood of isolating streptococcus. A score of 4 or 5 is thought to be associated with a 62 to 65% likelihood of isolating streptococcus
