Hospitalization and supportive treatments
In total, 16 (14.1%) patients required follow-up in the pediatric intensive care unit (PICU). Moreover, 56 (49.5%) received oxygen therapy via nasal cannula (NC), and 18 (15.9%) via high-frequency nasal cannula (HFNC). Thirteen (11.5%) patients were treated with noninvasive mechanical ventilation (NIMV) and 2 (1.8%) with invasive mechanical ventilation (IMV). In the CCAP group, hypoxia upon admission and the need for inhaled oxygen via NC during hospitalization were more common in the CCAP group than in the CAP group (p<0.001 and <0.001, respectively). CCAP patients commonly required HFNC (p=0.01). Admission at PICU and need for NIMV were more common in CCAP patients than in CAP patients (p<0.001 and <0.001, respectively). Meanwhile, the mean hospitalization durations in CAP and CCAP patients were 6.35±2.41 and 19.71±15.60 days, respectively. Therefore, the two groups significantly differed in terms of hospitalization duration (p<0.001) (Table-2). No patient developed systemic complications including sepsis, shock, and multiple organ failure.
