Primary Spontaneous Pneumothorax Outcomes in Children: A National Analysis.

OBJECTIVE

Considerable variation in primary spontaneous pneumothorax (PSP) management exists in the pediatric population. This study aims to compare nationwide outcomes of children with PSP.

METHODS

The Nationwide Readmissions Database (2016 to 2018) was used to identify patients 1 to 18 years old with PSP. Trauma, secondary pneumothoraces, and elective admissions were excluded. Demographics and complications were compared among patients undergoing initial nonoperative management (NOM; observation or percutaneous drainage) or operative resection using standard statistical tests.

RESULTS

A total of 3,890 patients were identified with PSP (median age, 16 [interquartile range 14 to 17] years). Most (78%) underwent NOM, of which 17% failed requiring operative resection. Of the intent-to-treat cohort, 28% failed NOM during index admission or required repeat percutaneous drainage or operative resection on readmission. Patients treated by NOM had higher 30-day and overall readmission rates compared with operative resection (all P < 0.001). Ipsilateral recurrent pneumothorax was higher in those receiving NOM (13% vs 3%, P < 0.001). Patients from the lowest median household income quartile more frequently received NOM compared with the highest income quartile (82% vs 76%) with more readmissions.

CONCLUSIONS

Patients with PSP who underwent initial NOM experienced higher readmission rates than those receiving operative resection. Furthermore, socioeconomic status was associated with the utilization of nonoperative versus operative management.
