Many mild chest, ear and throat infections can be managed without immediate antibiotics
Immediate versus delayed versus no antibiotics for respiratory infections.
Overview
Spurling GK et al.. Cochrane Database Syst Rev 2023 · PMID 37791590 · DOI 10.1002/14651858.CD004417.pub6
Delaying or not giving antibiotics for mild respiratory infections cut antibiotic use sharply with similar recovery and no difference in complications.
Does the study support the specific claim? Partly · Methodological quality: high
Plain-language summary
Study explained simply
- What did the researchers want to find out?
Compare immediate, delayed and no antibiotics for respiratory infections
- How was the study done?
Cochrane review of 12 randomised trials
- How many people, animals or samples were studied?
3968 children and adults
- What was actually found?
Similar outcomes for many symptoms; much less antibiotic use with delay
- How large was the observed effect?
Antibiotic use 30% vs 93% (delayed vs immediate)
- What do the results mean in everyday life?
For mild coughs, colds and sore throats, waiting is often safe when a doctor judges it so
- What are the study's limitations?
Mild infections only; rare complications poorly measured
- What does it say about Elawady's specific claim?
Supports only the 'overuse' part of the claim, not 'never take antibiotics'
- Do the results apply to Germany and Europe?
High
- What can explicitly not be concluded from this study?
Whether serious bacterial infections can be left untreated (they were not studied)

2. Research question
In acute respiratory tract infections, how do delayed, immediate and no antibiotic prescribing compare for symptoms, complications, antibiotic use and satisfaction?
3. Study design and population
- Study design
- Systematic review – Cochrane systematic review and meta-analysis of randomised controlled trials
- Population
Children and adults with acute respiratory infections (otitis media, sore throat, cough, common cold) in primary care, paediatric clinics and emergency departments
- Country
Multinational
- Period
Searches to 20 August 2022
- Sample size
12 RCTs, 3968 participants (3750 analysed)
- Inclusion and exclusion criteria
RCTs of all ages with an RTI; delayed prescription defined as advice to delay filling by at least 48 hours
4. Methods and endpoints
- Exposure / intervention
Delayed antibiotic prescription
- Comparator
Immediate antibiotics or no antibiotics
- Endpoints
Pain, malaise, fever, complications, adverse effects, antibiotic use, satisfaction
- Statistical methods
Odds ratios, random-effects meta-analysis; GRADE
5. Actual results
- Results
No differences for many clinical outcomes; immediate antibiotics modestly improved some symptoms of otitis media and sore throat; no differences in complication rates (low-certainty). Antibiotic use: delayed vs immediate OR 0.03 (95% CI 0.01-0.07; 30% vs 93%); delayed vs no antibiotics OR 2.52 (1.69-3.75). Satisfaction delayed vs no antibiotics OR 1.45 (1.08-1.96). No study evaluated resistance.
- Absolute risks
Antibiotic use 30% (delayed) vs 93% (immediate); 13% (no-antibiotic strategy) vs 27% (delayed)
- Authors' conclusion
Where clinicians feel it is safe not to prescribe immediately, no antibiotics with advice to return, or delayed antibiotics, reduce antibiotic use while maintaining similar outcomes; research should identify patients at high risk of complications.
6. Strengths
- Cochrane methods, RCTs only
- GRADE assessment
- Directly tests withholding antibiotics in mild infections
7. Weaknesses
- Only uncomplicated respiratory infections; excludes severe or high-risk patients
- Complication data are sparse (low certainty)
8. Risk of bias
- Orienting tool
- AMSTAR 2
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- low
- Rationale
High-quality review; certainty mostly moderate per authors.
9. Assessment of the statistical interpretation
Large relative reduction in antibiotic use without detectable harm in mild RTIs; the absence of a difference in rare complications is imprecise.
10. Relevance to the specific claim
Shows the correct part of the claim: many mild respiratory infections do not need immediate antibiotics. It does not cover serious bacterial infections.
11. Independent contrary findings
The review concerns mild, self-limiting infections; it gives no support for withholding antibiotics in sepsis, meningitis, pneumonia or other serious infections.
12. Transferability to Germany and Europe
High; trials include European primary care.
13. Overall methodological judgement
Strong evidence that antibiotics are often unnecessary in mild respiratory infections; supports stewardship, not blanket refusal.
