Abstract
Objectives
To explore the impact of COVID-19 on the management and outcomes of acute paediatric mastoiditis across the UK.
Design
National retrospective and prospective audit
Setting
48 UK secondary care ENT departments
Participants
Consecutive children aged 18 years or under, referred to ENT with a clinical diagnosis of mastoiditis.
Main outcome measures
Cases were divided into: Period 1 (01/11/19-15/03/20) before the UK population were instructed to reduce social contact, and Period 2 (16/03/20-30/04/21), following this. Periods 1&2 were compared for population variables, management and outcomes. Secondary analyses compared outcomes by primary treatment (medical/needle aspiration/surgical).
Results
286 cases met criteria (median 4 per site, range 0-24). 9.4 cases were recorded per week in period 1 versus 2.0 in period 2, with no winter increase in cases in Dec 2020-Feb 2021. Patient age differed between period 1&2 (3.2 Vs 4.7 years respectively, p<0.001). 85% of children in period 2 were tested for COVID-19 with a single positive test. In period 2 cases associated with P. aeruginosa significantly increased. 48.6% of children were scanned in period 1 vs 41.1% in period 2. Surgical management was used more frequently in period 1 (43.0% Vs 24.3%, p=0.001).
Treatment success was high, with failure of initial management in 6.3%, and 30-day re-admission for recurrence in 2.1%. The adverse event rate (15.7% overall) did not vary by treatment modality or between periods 1& 2.
Conclusion
The COVID-19 pandemic led to a significant change in the presentation and case-mix of acute paediatric mastoiditis in the UK.
