Introduction: Major orthopedic surgery such as total hip arthroplasty (THA) is associated with an increased risk of postoperative complications. Candidates for THA are often older adults, with comorbidities that increase the risk of major bleeding, the IMPROVE scale has independent actors on the risk of bleeding according to the characteristics of the patients at hospital admission. It foresees the possibility of hemorrhage and the need for blood transfusion, being support in decision-making in the planning of a safe THA with the provision of the necessary resources.
Objective: To evaluate the sensitivity, validity and reliability of the modified IMPROVE scale in patients undergoing primary total hip arthroplasty.
Material And Methods: Study of processes with a sample of 131 patients undergoing primary THA, in the period from January 01, 2018 to July 01, 2018.
Results: The scale presents good reliability, as for the performance of the scale, a good sensitivity was obtained, classifying 96.9% of the patients correctly; which is suitable for the type of scale.
Conclusions: The modified IMPROVE scale is a discretely adequate and useful tool for the prognosis of bleeding risk in patients who undergo THA, compared with other assessment scales developed in other geographical areas. It is recommended to continue with the study of risk factors for major bleeding in this specific population.
