Insights
The COVID-19 pandemic altered acute paediatric mastoiditis cases in the UK, reducing overall incidence but changing patient demographics. Management strategies shifted, though treatment success remained high.
Area of Science:
- Otolaryngology
- Paediatric Infectious Diseases
- Epidemiology
Background:
- Acute paediatric mastoiditis is a significant otolaryngological condition in children.
- Understanding the impact of public health crises on paediatric conditions is crucial for healthcare planning.
Purpose of the Study:
- To investigate the effects of the COVID-19 pandemic on the incidence, management, and outcomes of acute paediatric mastoiditis in the UK.
- To compare paediatric mastoiditis cases before and during the COVID-19 pandemic.
Main Methods:
- A national retrospective and prospective audit was conducted across 48 UK secondary care ENT departments.
- Cases of acute paediatric mastoiditis in children aged 18 years or under were analyzed, divided into pre-pandemic (Period 1) and pandemic (Period 2) phases.
- Management strategies and treatment outcomes were compared between the two periods and by treatment modality (medical, needle aspiration, surgical).
Main Results:
- A significant decrease in weekly cases of paediatric mastoiditis was observed during the pandemic (9.4 vs 2.0 cases/week).
- The pandemic period saw an increase in the average age of affected children and a rise in cases associated with Pseudomonas aeruginosa.
- Surgical management decreased during the pandemic, while overall treatment success remained high (6.3% initial management failure) and adverse event rates were consistent (15.7%).
Conclusions:
- The COVID-19 pandemic significantly altered the presentation and case mix of acute paediatric mastoiditis in the UK.
- Despite changes in incidence and patient demographics, management remained effective with consistently high success rates.
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 and 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 December 2020-Febraury 2021. Patient age differed between periods 1 and 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.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Tonsillitis II: Management
Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
