Management of per rectal bleeding is resource intensive.

BackgroundHaematochezia or per rectal (PR) bleeding is the most common presentation of lower gastrointestinal bleeding. This study analyses the hospital resources used in the management of patients with PR bleeding. MethodsA retrospective analysis was performed on patients who presented with PR bleeding from June 2012 to December 2013 to a single tertiary centre in Sydney, Australia. Age, gender, comorbidities, use of antiplatelet or anticoagulant medications, vital signs, and haematological data were recorded. The objective factors available on initial patient assessment were analysed for their relationship with the following outcomes: use of computed tomography mesenteric angiogram, formal angiography and embolization, transfusion of blood products, endoscopy, operative management and length of stay. ResultsThere were 523 confirmed presentations of PR bleeding. Four hundred and fifty-two of these presented directly to emergency department, while 71 were referred from another hospital. One in five patients had blood transfusion (19%), 13% had computed tomography mesenteric angiogram, 4% had embolization and 13% underwent diagnostic and/or therapeutic colonoscopy. Patients referred from other facilities were more comorbid (55% versus 30%), more likely to be on antiplatelet or anticoagulant (69% versus 33%) with a higher rate of embolization (28% versus 4%), more packed cell transfusions (2.1 versus 0.7units) and longer length of stay (7.9 versus 5.7days) but mortality was the same (1%). ConclusionsThe management of patients with PR bleeding is resource intensive. Better identification and allocation of resources in patients who present with PR bleeding may lead to better efficiency in managing this growing clinical problem.
