Study summary

Epistaxis is a common disorder with 60% of the population suffering from one episode and 10% of these cases requiring medical attention. Between March 2006 and March 2007, in Calgary, Alberta, there were 1500 presentations of epistaxis to adult emergency rooms with 7% of these (105 patients) requiring packing with admission. Common methods to control epistaxis include, nasal packing (88%), operative arterial ligation (10%), and arterial embolization (2%). A cost analysis demonstrated that nasal packing had a lower cost compared to embolization and arterial ligation, and all modalities had similar lengths of stay (Goddard, Otolaryng Head Neck Surg. 2006). Arterial ligation is the current recommended therapy for recurrent or refractory epistaxis, with a success rate of 98%. With the advancement of endoscopic techniques, emergency room Minimally Invasive Control of Epistaxis (M.I.C.E.) allows for selective packing and cauterization, which provides the patient with retained function of their nasal cavity and prevents a hospital admission, resulting in significant cost savings.

Hypothesis:

Does the M.I.C.E. procedure provide significant cost savings compared to operative sphenopalatine artery ligation? Null hypothesis is that there is no difference in hospital admission rates between M.I.C.E. and operative sphenopalatine artery ligation.

The record gives a start of Jun 2008, a primary completion of Jun 2009 and a completion of Jun 2009. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 12, 2009, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
