Abstract
Abstract Aim The United Kingdom was affected by the COVID-19 pandemic with the reduction of many services within the NHS, including suspension of elective surgical procedures from March 2020. We hypothesised that delayed surgery caused by the pandemic may increase the risk of post-tonsillectomy haemorrhage due to increased episodes of tonsillitis. The aims of this review were to investigate the relationship between prolonged waiting times and post-tonsillectomy haemorrhage. Method We performed a single-site, retrospective review from March 2019 to August 2023, with data collected from electronic hospital records. Both adults and children were included in the analysis and only procedures performed for recurrent tonsillitis were included. Results We identified 234 cases: 184 adeno/tonsillectomies in the pre-COVID (March 2019-20) and 50 in the post-COVID (August 2020-21) cohort. In the pre-COVID cohort, 7.6% (n=14) experienced a post-tonsillectomy haemorrhage, with 1.1% (n=2) experiencing a primary haemorrhage and 6.5% (n=12) experiencing secondary haemorrhage. The return to theatre rate was 2.2% (n=4). Median waiting time for surgery was 78 days. In the post-COVID cohort, secondary haemorrhage occurred in 6.0% (n=3). No patients experienced a primary haemorrhage and return to theatre rate was 0%. Median waiting time was 345 days. Simple logistic regression was performed which showed no significant association between waiting times and post-tonsillectomy haemorrhage across the whole (p = 0.90, 95% CI [-0.0002, 0.0002]) cohort. Conclusions Our cohort demonstrated no significant relationship between prolonged waiting times and post-tonsillectomy haemorrhage. Small sample size was a significant limitation; we recommend a larger scale, multi-centre study to investigate this further.
