Upper respiratory tract infections (URTIs) are responsible for a large amou
nt of community antibacterial use worldwide. Recent systematic reviews have
demonstrated that most URTIs resolve naturally, even when bacteria are the
cause. The high consumer expectation for antibacterials in URTIs requires
intervention by the general practitioner and a number of useful strategies
have been developed.
Generic strategies, including eliciting patient expectations, avoiding the
term 'just a virus', providing a value-for-money consultation, providing ve
rbal and written information, empowering patients, conditional prescribing,
directed education campaigns, and emphasis on symptomatic treatments, shou
ld be used as well as discussion of alternative medicines when relevant.
The various conditions have differing rates of bacterial infection and requ
ire different approaches. For acute rhinitis, laryngitis and tracheitis, vi
ruses are the only cause and, therefore, antibacterials are never required.
In acute sore throat (pharyngitis) Streptococcus pyogenes is the only impo
rtant bacterial cause. A scoring system can help to increase the likelihood
of distinguishing a streptococcal as opposed to viral infection, or altern
atively patients should be given antibacterials only if certain conditions
are fulfilled. Strategies for treating acute otitis media vary in different
countries. Most favour the strategy of prescribing antibacterials only whe
n certain criteria are fulfilled, delaying antibacterial prescribing for at
least 24 hours. In otitis media with effusion, on the other hand, there is
no primary role for antibacterials, as the condition resolves naturally in
almost all patients aged >3 months. Detailed strategies for acute sinusiti
s have not been worked out but restricting antibacterial prescribing to cer
tain clinical complexes is currently recommended by several authorities bec
ause of the high natural resolution rate.
