Abstract
Introduction
There is a paucity of literature regarding “flagged PSGs”, a term used to triage emergent PSGs for expedited scoring and reporting. Given the morbidity and multi organ-system dysfunction of untreated OSAS in children, it is extremely important to identify and treat expediently. The aim of this study was to review flagged PSGs at a tertiary level pediatric sleep center, including management and intervention timelines.
Methods
This is an IRB-approved retrospective chart review of flagged PSGs (N=266) over a three-year period (2019-2022) at a pediatric sleep center. PSGs were flagged based on laboratory protocols and provider discretion. Demographic, clinical, and PSG data were obtained from EMR.
Results
Patients with flagged studies were white (49.2%), non-Hispanic (87.2%), males (66.9%) with (mean ± SD) age (6.9 ± 6.0) years and BMI of (23.3 ± 11.6) kg/m2, respectively. Reasons for flagging studies were repetitive brief oxygen desaturations < 80% (46.6%), sustained desaturations < 85% (32.3%), sustained EtC02 >60mmHg (5.6%), or other concerning events (15.5%). Most common comorbidity was pulmonary (41.4%), followed by genetic (30.5%), cardiac (23.3%), and neuromuscular (11.7%). 23.3% children were obese. 30.1% had prior airway surgeries; most commonly being adenotonsillectomy (70.0%). Mean Apnea-hypopnea index was 47.2 ± 36.1 events/hr. 35% children had hypoxemia and 36.8 % had hypoventilation. Time duration from flagging study to finalized report, surgical, or medical intervention was 4.3 ± 6.0, 78.2 ± 105 and 26.6 ± 93.0 days, respectively. Medical (40.6%) and surgical (37.9%) intervention were similar in frequency; however, children < 8 were more likely to undergo surgery (p< 0.001). Most frequent surgical intervention was adenotonsillectomy (82.1%). Patients with AHI>30 had less time between PSG and surgical intervention (65.3 ± 96.7 days vs 112 ± 119 days, p=0.04).
Conclusion
Most frequent reason for flagging PSG was repetitive brief desaturations. Time to surgical intervention was longer than medical intervention; however, they occurred in similar frequency. Pandemic staffing shortages and PAP machine recalls impacted both interventions. Patients with higher disease severity experienced quicker scoring, report finalization, and surgical intervention. Future directions include establishing protocols between sleep laboratory and surgical teams, assess the impact of this and further streamline care.
