An Algorithm for Predicting Blood Loss and Transfusion Risk in Fast Track Total Hip Arthroplasty

• Conditions: Total Hip Replacement; Blood Loss

• Registration Number: NCT02750852
• Lead Sponsor: Azienda Ospedaliera Bolognini di Seriate Bergamo

Brief Summary

Aim of these study is to create an algorithm, using data from patients that undergoing total hip arthroplasty, to predict blood loss after surgery and permit a safe domestic discharge.

Detailed Description

Two different cohorts of patients undergoing total hip arthroplasty will be analyzed to obtain data about hemoglobin trends. The first group will be used to obtain the algorithm, the second one to validate results of the first group, determining sensitivity and specificity.

Primary Outcome Measures

Name	Time	Method
Create an algorithm to predict blood loss after total hip arthroplasty	3 months	Data from the fist cohort of patients have been collected and analyzed to obtain an algorithm describing the trends of hemoglobin values after total hip arthroplasty. These algorithm was after applied to patients of a second cohort of consecutive patients undergoing total hip arthroplasty to determine specificity and sensitivity.
