supportive care

Non-severe CAP in a previously healthy child can be safely managed in the community.[1][9]​​​​​

Ensure that appropriate safety-netting advice is provided to carers, with information on managing fever, preventing dehydration, and identifying deterioration. Advise them to bring the child for reassessment if any of the following features is present: a high swinging or persistent fever that continues >48 hours after antibiotic treatment has started; any signs of harder work of breathing, such as a fast respiratory rate or chest recession; breathing makes the child agitated and distressed; symptoms do not start to improve within 3 days.​[3][9][18]​​​​​​​

Fever may be treated with an antipyretic (e.g, paracetamol, ibuprofen). Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may cause cardiovascular, renal, and gastrointestinal adverse effects. Use the lowest effective dose for the shortest treatment duration possible.

Doses recommended here are for children. Adolescents may receive paediatric or adult doses depending on the drug, the patient's age and weight, and clinical factors. Consult your local drug information source for dose recommendations for adolescents.

Primary options

paracetamol: consult product literature for guidance on dose

empirical oral antibiotic therapy

Treatment recommended for ALL patients in selected patient group

Give antibiotics to any child who has a clinical diagnosis of CAP.[1]​​[3][9][18]​​​​​ The only exception is a child <2 years of age who has mild symptoms and is fully vaccinated (including with pneumococcal vaccine); in these circumstances, the CAP is unlikely to be bacterial so do not prescribe antibiotics unless symptoms become more severe.[1][9]​​ In the UK, the National Institute for Health and Care Excellence (NICE) recommends starting antibiotic therapy within 4 hours of making the diagnosis.

Treatment of CAP in children with non-severe disease is empirical. Microbiological investigations are not indicated.[1][9][19]​​​

High-dose oral amoxicillin is the first-line antibiotic for any previously healthy child ≥3 months of age with non-severe CAP who is being managed in the community.[1][9][18]​ Amoxicillin provides appropriate coverage for Streptococcus pneumoniae, the most common typical bacterial pathogen.[1]

Amoxicillin/clavulanate is an alternative option and is recommended for CAP associated with influenza.[1][9]

First-line alternatives for children who are allergic to penicillins include levofloxacin, linezolid, a second- or third-generation cephalosporin (e.g., cefprozil, cefpodoxime), or a macrolide (e.g., azithromycin, clarithromycin, erythromycin).[1][10]​​[18]

Consider adding a macrolide if there is a poor response, with no improvement after 48 hours.​[3][9]​​​​​

The US paediatric CAP guideline does not cover infants <3 months of age but states that infants in that age group are generally admitted to hospital for initial management. In the UK, NICE recommends oral amoxicillin for non-severe CAP for infants aged 1-3 months and referral to a paediatric specialist for advice on the appropriate antibiotic regimen for any child <1 month of age.[18] In practice, there is a low threshold for referring any infant <3 months of age to hospital for assessment and treatment.

Macrolides have been associated with altered cardiac conduction (e.g., QT interval prolongation, arrhythmias including torsades de pointes).

Systemic fluoroquinolone antibiotics may cause serious, disabling, and potentially long-lasting or irreversible adverse events. This includes, but is not limited to: tendinopathy/tendon rupture; peripheral neuropathy; arthropathy/arthralgia; aortic aneurysm and dissection; heart valve regurgitation; dysglycaemia; and central nervous system effects including seizures, depression, psychosis, and suicidal thoughts and behaviour.[70]​ Prescribing restrictions apply to the use of fluoroquinolones, and these restrictions may vary between countries. In general, fluoroquinolones should be restricted for use in serious, life-threatening bacterial infections only. Some regulatory agencies may also recommend that they must only be used in situations where other antibiotics, that are commonly recommended for the infection, are inappropriate (e.g., resistance, contraindications, treatment failure, unavailability).Consult your local guidelines and drug information source for more information on suitability, contraindications, and precautions.

Check your local protocol for advice on the duration of antibiotic therapy. Empirical antibiotic treatment has traditionally been given for 7-10 days.[1][3]​​​​​​ However, evidence now suggests that a shorter course is likely to be sufficient in children with non-severe CAP who are treated as outpatients.[10] One Cochrane review found no significant difference in outcomes when comparing a 3-day versus 5-day course of antibiotics for non-severe CAP in children aged 2-59 months in low-income countries.[59]​ A subsequent randomised controlled trial of clinically diagnosed CAP found that a 3-day course of amoxicillin was non-inferior to a 7-day course in children with clinically diagnosed CAP (although some participants had received prior antibiotic therapy).[60]​ Another randomised trial comparing a 5-day versus 10-day course of high-dose amoxicillin in 380 previously healthy children aged 6-71 months with non-severe CAP found that those treated with the shorter course had a similar clinical response and less colonisation with antibiotic-resistant bacteria.[61]​ A meta-analysis of nine randomised clinical trials including 11,143 children aged 2-59 months with non-severe CAP found that for the outcome of treatment failure, a 3-day course of antibiotic therapy was non-inferior to a 5-day course (risk ratio 1.01, 95% CI 0.91 to 1.12) and a 5-day course was non-inferior to a 10-day course (risk ratio 0.87, 95% CI 0.50 to 1.53).[62] In the UK, NICE recommends a 5-day course, with treatment only continued if microbiological results or clinical signs suggest that a longer course is needed.[18]

Any child receiving appropriate antimicrobial therapy should start to show clinical and laboratory signs of improvement within 48-72 hours.[1] Arrange prompt reassessment and consider further investigations and/or an escalation of care setting if this is not the case.[1]

antiviral therapy

Additional treatment recommended for SOME patients in selected patient group

Guidelines vary on indications for antiviral therapy in children with assumed or confirmed influenza-associated CAP. Check your local protocol.

In the UK, hospital-based clinicians can prescribe oseltamivir or zanamivir for treatment of suspected or confirmed influenza at any time, but prescribing in the community is limited to periods when the influenza virus is circulating.[63][64][65]​​​​​

The World Health Organization (WHO) influenza guideline recommends against the use of oseltamivir, zanamivir, and other antivirals in patients with non-severe influenza, with the only exception being a conditional recommendation, based on low-quality evidence, to consider baloxavir for non-severe influenza in patients at high risk of progression to severe disease.[66]​ The WHO also makes a conditional recommendation, based on low-quality evidence, for use of oseltamivir to treat patients with severe influenza.[66]

US guidelines recommend early initiation of antiviral therapy for any child with assumed or confirmed influenza-related CAP who is treated as an outpatient and who either has progressively worsening symptoms or is at high risk for complications (regardless of symptom severity).[55][67]​​​ Antiviral therapy can be considered for other children treated as outpatients after consideration of benefits versus risks and provided it can be initiated within 48 hours of symptom onset.[55][67]

Oseltamivir is the usual first-line antiviral drug.​[55][63]​​​ However, there has been extensive debate over the use of oseltamivir and whether or not it does reduce complications in otherwise healthy children.[68][69]​​​​

In practice, many clinicians find that the increased risk of adverse effects (e.g., nausea and vomiting) in children outweighs any benefits. For more details, see Influenza infection.

If an antiviral is used, it is generally used alongside antibiotic treatment because of the high incidence of co-infection (although note that the WHO recommends against use of antibiotics for patients with non-severe influenza and low probability of bacterial co-infection).[66]

inpatient management

Additional treatment recommended for SOME patients in selected patient group

If the child does not respond to oral outpatient antimicrobial therapy and has developed signs of respiratory distress, arrange hospital admission and treat as an inpatient.[1]

Hospital admission is indicated for any child with severe pneumonia or CAP with suspected complications.[1][9]​​​​ Base the assessment of severity on symptoms, signs, and risk factors for severe disease.[1][9]​​​ Look for any signs of sepsis.​[2][9]​​​​ See Sepsis in children. For details on categorising severity of CAP and criteria for hospital admission, see Diagnosis approach.

The US paediatric CAP guideline states that infants <3 months of age with CAP are generally admitted to hospital, and recommends to consider hospital admission for any child aged 3-6 months who has suspected bacterial CAP.[1]

Hospital admission is indicated for any child with severe pneumonia or CAP with suspected complications.[1][9]​​​​ Base the assessment of severity on symptoms, signs, and risk factors for severe disease.[1][9]​​ Look for any signs of sepsis. (See Sepsis in children.)​[2][9]​​ For details on categorising severity of CAP and criteria for hospital admission, see Diagnosis approach. The US paediatric CAP guideline also states that infants <3 months of age with CAP are generally admitted to hospital, and recommends to consider hospital admission for any child aged 3-6 months who has suspected bacterial CAP.[1]

Ensure ongoing monitoring of fever, respiratory rate, oxygen saturation, and respiratory distress (e.g., signs of chest retractions, grunting, nasal flaring).[1] If there is increased work of breathing, ensure continuous monitoring of oxygen saturation.[1] Look for any signs of sepsis and manage or escalate to senior colleagues accordingly. See Sepsis in children.

Fever may be treated with an antipyretic (e.g, paracetamol, ibuprofen). Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may cause cardiovascular, renal, and gastrointestinal adverse effects. Use the lowest effective dose for the shortest treatment duration possible.

If the child is hypoxaemic, provide supplemental oxygen by nasal cannula or face mask (or a head box if needed for an infant).[1]​​[3][9]​​ In most cases this will be sufficient to restore oxygen saturation.[1] Target an oxygen saturation >92%.[9] If a child requires fraction of inspired oxygen (FiO₂) ≥0.50 to maintain saturation >92%, admit them to a unit with capability for continuous cardiorespiratory monitoring.

Give fluid therapy if the child is unable to maintain their fluid intake due to breathlessness, fatigue, or vomiting. Patients who are vomiting or are severely ill may also need intravenous fluids.​[3][9]​​​ Use isotonic intravenous fluid.[2] Measure electrolytes (in particular, sodium and potassium), urea, and creatinine at baseline.[9] Hyponatraemia (serum sodium <135 mEq/L) is common in children admitted to hospital with respiratory infection. One retrospective analysis of 312 children admitted with CAP found that hyponatraemia was present in 33% and was correlated with disease severity.[71]​ Hence, use isotonic rather than hypotonic intravenous fluid to maintain hydration.[2][72]

Criteria for escalation to the intensive care unit (ICU) vary, so seek specialist advice and/or check your local protocol.

The US Pediatric Infectious Diseases Society and Infectious Diseases Society of America (PIDS/IDSA) guideline recommends referral to a paediatric ICU if a child requires invasive ventilation or has oxygen saturation <92% on FiO₂ ≥50%.[1] It further recommends to arrange admission to an ICU or a unit with continuous cardiorespiratory monitoring capability if a child: requires use of non-invasive positive pressure ventilation (e.g., continuous positive airway pressure [CPAP] or bilevel positive airway pressure); has impending respiratory failure (e.g., as indicated by grunting); has sustained tachycardia, inadequate blood pressure, or need for pharmacological support of blood pressure or perfusion; or has altered mental status as a result of pneumonia, whether due to hypercarbia or to hypoxaemia.[1]

In the UK, the British Thoracic Society guideline recommends referral to ICU for: development of respiratory failure requiring assisted ventilation; pneumonia complicated by sepsis; failure to maintain oxygen saturation >92% with FiO₂ >60%; clinical features of shock; increasing respiratory and heart rates with severe respiratory distress and exhaustion, with or without raised pCO₂; or recurrent apnoea or slow, irregular breathing.[9]

empirical antibiotic therapy

Treatment recommended for ALL patients in selected patient group

The choice of empirical antibiotic regimen, route of administration, and duration of therapy for an infant in this age group is individualised after specialist discussion.[18]

Appropriate options might include ampicillin (amoxicillin may be preferred in the UK and some other countries) plus an aminoglycoside (e.g., gentamicin) or cefotaxime.[8]

If an atypical pathogen is suspected, empirical regimens differ from those recommended here. See Atypical pneumonia.

Any child receiving appropriate antimicrobial therapy should show clinical and laboratory signs of improvement within 48-72 hours. If this is not the case: consider an escalation of care setting; repeat chest radiography and consider other imaging to assess the extent and progression of the pneumonic or parapneumonic processes; and consider further investigations to determine whether the initial pathogen is persistent or has developed resistance to the antimicrobial agent(s) used, or if there is a new secondary infection.[1]

In the US, parenteral therapy is recommended.[1][8]​​​​​ However, oral antibiotics may be recommended in some countries outside of the US; they are safe and effective for severe CAP, if tolerated.[9][53][54]​​​​​​​

The US paediatric CAP guideline recommends empirical therapy with high-dose ampicillin or benzylpenicillin first-line for any previously healthy, fully immunised child who is hospitalised with presumed bacterial CAP (assuming there are no local reports of high-level penicillin resistance for invasive Streptococcus pneumoniae). A third-generation cephalosporin (e.g., ceftriaxone, cefotaxime) is an alternative option.[1] Empirical therapy with a third-generation cephalosporin is recommended first-line if one or more of the following apply: the child is not fully immunised; or there is local evidence of significant penicillin resistance for invasive S pneumoniae; or the child has life-threatening infection. Levofloxacin is an alternative option in these patients. Patients on intravenous therapy may be switched to a suitable oral regimen when possible to complete the course.

In the UK, high-dose amoxicillin is recommended by the National Institute for Health and Care Excellence (NICE) and the British Thoracic Society (BTS) as the first-line antibiotic for most children.[9][18]​​​ If the child has high-severity CAP, NICE recommends amoxicillin/clavulanate first-line.[18] UK guidelines recommend to use intravenous antibiotics only if a child is unable to tolerate oral fluids (e.g., because of vomiting) and/or has signs of sepsis or complicated pneumonia.[18]

If an atypical pathogen is suspected, empirical regimens differ from those recommended here. See Atypical pneumonia.

Systemic fluoroquinolone antibiotics may cause serious, disabling, and potentially long-lasting or irreversible adverse events.

High-quality guidelines for CAP in children are inconsistent in their recommendations on duration of antibiotic therapy, varying from 3 to 10 days for uncomplicated disease, with longer courses for severe or complicated disease, CAP caused by certain specific organisms, and children with pre-existing comorbidities.[7]​ In the UK, NICE recommends a 5-day course, with treatment only continued if microbiological results suggest that a longer course is needed or the child is not clinically stable (i.e., fever in the past 48 hours, or >1 sign of clinical instability [systolic blood pressure <90 mmHg, heart rate >100 beats/minute, respiratory rate >24 breaths/minute, arterial oxygen saturation <90%, or PaO₂ <60mmHg on room air]).[18]
