Insights
Pediatric community-acquired pneumonia (CAP) outpatient visit rates remained stable from 1994-2007. Broad-spectrum antibiotics were frequently prescribed for pediatric CAP, despite limited evidence of benefit over narrow-spectrum options.
Area of Science:
- Pediatric infectious diseases
- Public health surveillance
- Antibiotic stewardship
Background:
- Pediatric hospitalizations for community-acquired pneumonia (CAP) have decreased following widespread heptavalent pneumococcal conjugate vaccine use.
- National incidence rates for outpatient pediatric CAP are not well-established.
- Current pediatric CAP treatment often relies on narrow-spectrum antibiotics, though specific guidelines are lacking.
Purpose of the Study:
- Estimate incidence rates of outpatient pediatric CAP.
- Analyze trends in antibiotic prescribing for pediatric CAP.
- Identify factors associated with broad-spectrum antibiotic use in pediatric CAP.
Main Methods:
- Utilized National Ambulatory and National Hospital Ambulatory Medical Care Surveys (1994-2007).
- Identified pediatric CAP cases (ages 1-18) using a validated algorithm.
- Examined age-specific CAP rates, antibiotic prescribing trends, and factors influencing broad-spectrum antibiotic use.
Main Results:
- Annual outpatient CAP visit rates ranged from 16.9 to 22.4 per 1000 children, with highest rates in ages 1-5.
- Outpatient CAP visit rates showed no significant change between 1994 and 2007.
- Macrolides and cephalosporins were commonly prescribed, with cephalosporin use increasing significantly from 2000-2007.
Conclusions:
- Pediatric ambulatory CAP incidence remained stable between 1994-2007, irrespective of pneumococcal vaccination.
- Broad-spectrum antibiotics, particularly macrolides, were frequently prescribed for pediatric CAP.
- Prescribing broad-spectrum antibiotics was associated with increasing patient age, non-emergency department visits, and diagnostic testing.
Background:
The incidence of pediatric hospitalizations for community-acquired pneumonia (CAP) has declined after the widespread use of the heptavalent pneumococcal conjugate vaccine. The national incidence of outpatient visits for CAP, however, is not well established. Although no pediatric CAP treatment guidelines are available, current data support narrow-spectrum antibiotics as the first-line treatment for most patients with CAP.
Objective:
To estimate the incidence rates of outpatient CAP, examine time trends in antibiotics prescribed for CAP, and determine factors associated with broad-spectrum antibiotic prescribing for CAP.
Patients And Methods:
The National Ambulatory and National Hospital Ambulatory Medical Care Surveys (1994-2007) were used to identify children aged 1 to 18 years with CAP using a validated algorithm. We determined age group-specific rates of outpatient CAP and examined trends in antibiotic prescribing for CAP. Data from 2006-2007 were used to study factors associated with broad-spectrum antibiotic prescribing.
Results:
Overall, annual CAP visit rates ranged from 16.9 to 22.4 per 1000 population, with the highest rates occurring in children aged 1 to 5 years (range: 32.3-49.6 per 1000). Ambulatory CAP visit rates did not change between 1994 and 2007. Antibiotics commonly prescribed for CAP included macrolides (34% of patients overall), cephalosporins (22% overall), and penicillins (14% overall). Cephalosporin use increased significantly between 2000 and 2007 (P = .002). Increasing age, a visit to a nonemergency department office, and obtaining a radiograph or complete blood count were associated with broad-spectrum antibiotic prescribing.
Conclusions:
The incidence of pediatric ambulatory CAP visits has not changed significantly between 1994 and 2007, despite the introduction of heptavalent pneumococcal conjugate vaccine in 2000. Broad-spectrum antibiotics, particularly macrolides, were frequently prescribed despite evidence that they provide little benefit over penicillins.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Atypical Pneumonia
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
