Incidence of post-tonsillectomy haemorrhaging in Denmark

Tonsillectomy is one of the most common procedures in the field of ear, nose and throat procedures. In 2012, the annual incidence in Denmark was 129.4 per 100,000 inhabitants.

Summary:Tonsillectomy is one of the most common procedures in the field of ear, nose and throat procedures. In 2012, the annual incidence in Denmark was 129.4 per 100,000 inhabitants. A common complication is post-tonsillectomy haemorrhaging (PTH). The overall PTH rates vary widely among studies ranging from 0.5% to 33%. This was a nationwide open-population, retrospective and registry-based cohort study in Danes who underwent tonsillectomy complicated by PTH in hospitals and private otorhinolaryngology (ORL) offices in the period from 1991 to 2012. In the 1991-2012 period, a total of 177,211 tonsillectomies were performed among which 9,221 had a registered PTH (rPTH) (5.2%). The annual incidence rate of rPTH increased from 3% in 1991 to 13% in 2012 (p less-than 0.05). Males aged 20-40 years had a significantly higher risk of rPTH with the highest increase in rPTH incidence rates from 9.0% in 1998 to 16.4% in 2012 (p less-than 0.05). Approx. 12% had a primary rPTH within the first 24 hours; the maximum incidence of rPTH was on day six (14%). The rate of rPTH increased from 1991 to 2012 in hospitals and in private ORL office settings alike. There was a significantly higher rate of rPTH in the age group of 20-40 years and a significant geographical difference in rPTH. The highest risk of rPTH was observed on the day of surgery and on day six. The Danish Data Protection Agency (record number 2012-41-0158) approved this study. The Olga Bryde Nielsen Foundation and H. Skouby & E. Skouby's Foundation supported this study financially.
