Abstract [en]

Objectives: Post-surgical haemorrhage is the major complication of tonsil surgery. Post-tonsillectomy haemorrhage often results in readmission to hospital, sometimes demands return to theatre and can be a life-threatening occurrence. There are large differences in previously reported rates of post-tonsillectomy haemorrhage. The aim of this study is to determine readmission rates due to post-tonsillectomy haemorrhage in Sweden 2012-2014.

Method: This is a population-based cohort study based on matched data from two healthcare registries in Sweden; the Swedish National Patient Register (NPR) and the National Tonsil Surgery Register in Sweden (NTSRS). All patients who underwent tonsillectomy, with or without simultaneous adenoidectomy, on benign indications from 2012 to 2014 were included in the study. The unique Personal Identity numbers were used to follow patients over time in NPR and identify readmission due to haemorrhage within 30 days from surgery. In NTSRS, readmission was reported by the patient in a questionnaire 30 days after surgery.

Results: By matching the two registries a total of 22 800 unique patients were identified and included in the study. A total of 1726 patients (7.6%) were readmitted to hospital due to post-surgical haemorrhage. Tonsil surgery was conducted at 56 different surgical centres. Readmission rates due to post-tonsillectomy haemorrhage ranged from 0% to 22.4% at different surgical centres. 11 of 56 surgical centres had significant lower readmission rates compared to the average in Sweden. 12 of 56 surgical centres had significant higher readmission rates than the average.

Conclusions: The rate of hospital readmissions due to post-surgical haemorrhage following tonsillectomy in Sweden 2012-2014 was 7.6%. There were significant differences in readmission rates between different surgical centres. This suggests that quality improvement interventions should be explored in units with high readmission rates to decrease post-tonsillectomy morbidity.
