Insights
Spontaneous pneumothorax (SP) incidence in children is increasing, primarily affecting adolescent males. Many pediatric SP cases are managed without surgical procedures.
Area of Science:
- Pediatric Pulmonology
- Epidemiology
- Thoracic Surgery
Background:
- Spontaneous pneumothorax (SP) research predominantly focuses on adults and adolescents.
- Limited population-based data exists for pediatric SP incidence and trends.
Purpose of the Study:
- To determine the incidence of spontaneous pneumothorax (SP) in the pediatric population.
- To analyze SP incidence across different pediatric age groups.
Main Methods:
- Retrospective analysis of pediatric patients (0-17 years) hospitalized with SP.
- Utilized the Healthcare Cost and Utilization Project Kids' Inpatient Database (1997-2006).
- Examined trends in incidence, demographics, length of stay, procedures, and associated conditions.
Main Results:
- Overall pediatric SP incidence rose from 2.68 to 3.41 per 100,000 population (1997-2006).
- Males were 4.2 times more likely than females to develop SP in 2006.
- Common procedures included chest tube (32%), bleb excision (20%); common diagnoses were emphysematous bleb (21%) and asthma (10%).
Conclusions:
- Spontaneous pneumothorax (SP) is uncommon but increasing in pediatric males and adolescents.
- A significant portion of pediatric SP cases are managed non-procedurally.
- Highlights the need for further research into pediatric SP etiology and management.
Objectives:
Research on spontaneous pneumothorax (SP) has focused on management strategies in adolescents and adults, yet pediatric population-based data are lacking. The objective of this study was to determine the incidence of SP in the pediatric population in different age groups.
Methods:
This was a retrospective analysis of patients aged 0 to 17 years hospitalized with a diagnosis of SP from the Healthcare Cost and Utilization Project Kids' Inpatient Database between 1997 and 2006. Trends of overall incidence and demographic information, including age, sex, length of stay, associated procedures, and associated conditions, were obtained and analyzed.
Results:
The overall incidence of SP in children younger than 18 years increased from 2.68 per 100,000 population in 1997 to 3.41 per 100,000 in 2006. Average age (15.1 years; SE, 0.1 years), age distribution (83% = 15-17 years old), and hospital length of stay (4.7 days; SE, 0.1 days) remained constant. Between 1997 and 2006, males rose from 3.7 times to 4.2 times as likely to develop SP as females. In 2006, 70% of all hospitalized SP patients had therapeutic procedures documented: chest tube (32%), bleb excision (20%), and thoracotomy (8%) were the most common. Emphysematous bleb (21%), asthma (10%), and tobacco use (4%) were the most common associated diagnoses in 2006.
Conclusions:
Although uncommon in children, SP appears to be primarily a condition of males and adolescents and appears to be increasing in incidence in this population. According to these data, a large portion of children are being managed without procedural intervention.
