Increasing Readmission Rates for Hemorrhage after Tonsil Surgery: A Longitudinal (26 Years) National Study:

ObjectiveTo investigate the readmission rates due to postoperative hemorrhage in relation to tonsil surgery clinical practice in a national population.Study DesignRetrospective longitudinal population-based cohort study.SettingBased on register data from the Swedish National Patient Register (NPR).Subjects and MethodsAll benign tonsil operations (256 053) performed in Sweden from 1987 to 2013 were identified through a search in the NPR. For all identified cases, data on gender, age, date of surgery, indication, type of surgery, level of care, length of stay (LOS) for inpatient surgery, readmission and reoperation because of postoperative bleeding (within 31 days) were collected.ResultsOverall frequency of readmission for hemorrhage was 2.61%, and the reoperation rate for hemostasis was 0.84%. The longitudinal analysis showed an increase from 1% (1987) to 5% (2013) in readmissions caused by hemorrhage. Tonsillectomies, surgery performed for infectious disease, and surgery on adult patients (age >18 years) ...
