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\u00a0days) were collected.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall 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 &gt;18 years) showed readmission rates approaching 10% (2013). Male gender, increasing age, tonsillectomy, infectious indication, and recent year of surgery were identified as risk factors for readmission and reoperation due to hemorrhage. An increasing share of patients readmitted for hemorrhage underwent reoperation for hemostasis: 18% (1987) versus 43% (2013).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Readmissions for hemorrhage have increased by a factor of 5\u00a0in Sweden from 1987 to 2013.
