Recommendations

≥ 18 years
Dosage Remarks
1st choice
cefuroxime IV 1500 mg tds for 5 days

AMBU-65 score 4 or 5**: add hydrocortisone 50 mg IV four times daily for 5 days, or shorter with clinical recovery. Not for aspiration or influenza.

 

- If the patient has not clinically improved and does not meet clinical stability criteria* on day 5, extend total antibiotic duration to 7 days

- If the patient is immunocompromised, then treatment duration 7 days

- Consider Pseudomonas coverage in patients colonised with Pseudomonas spp

1st choice
benzylpenicillin IV 1 million IU four times daily

+

ciprofloxacin IV 400 mg three times daily

In case of documented (<1 year) airway colonisation with Pseudomonas spp

If there is recent (<1 year) airway colonisation with ESBL: adjust empirical management accordingly.

≥ 18 years

Indications: For (possible) aspiration

Dosage Remarks

Treat as CAP.

Only in massive aspiration may anaerobic coverage be considered: amoxicillin-clavulanic acid IV 1000/200 mg four times daily for 3 days.

 

Comments

In case of (suspected) allergy to penicillins and/or cephalosporins:

See protocol: Management of antibiotic allergy | Radboud UMC

Consult the medical microbiologist/infectious diseases physician for an alternative regimen.

Other remarks:

Treatment depends on the severity of the pneumonia. This is based on the number of criteria of the AMBU-65 score that the patient meets:

AMBU-65 score:

  • Respiratory rate > 30 per minute
  • Mental status: recent disorientation in time, place or person
  • Blood pressure systolic < 90 mmHg and/or diastolic < 60 mmHg
  • Urea > 7 mmol/l
  • Age > 65 years

A pneumococcal urinary antigen test must be performed within 12-24 hours; if positive, therapy can be narrowed to penicillin IV or amoxicillin IV.

A Legionella urinary antigen test must be performed within 12-24 hours.

For information about influenza virus (flu): see LWI 4 Pneumonia: (viral) influenza

**indication for steroids:

  • AMBU-65 score 4 or 5 OR
  • HFNO with FiO2 > 50% and PaO2:FiO2 ratio < 300 OR
  • non-rebreathing mask with PaO2:FiO2 ratio < 300

Adjust antibiotics where possible based on culture results.

* clinical stability criteria

  • Temperature < 37.8°C
  • Pulse < 100
  • Respiratory rate < 24
  • SpO2 > 90 (without mechanical ventilation, without oxygen mask; oxygen delivery via nasal cannula is allowed)
  • Systolic blood pressure > 90

No signs of delirium
