Hip Outcome Score
Introduction[edit | edit source]
Hip Outcome Score (HOS) is a patient-reported outcome measure designed to assess the outcome of treatment intervention for individuals with acetabular tears.[1]
Objective[edit | edit source]
The purpose of this instrument was used to assess self-reported functional status of patient with labral tear. Therefore, according to the terms defined by the International Classification of Functioning, Disability and Health model items that related to activity and participation were included whereas items relating to body structure and function (i.e., symptoms) were not considered.[1] full spectrum of functional activities and sports-related activities was included.
Methods of Use[edit | edit source]
HOS consists of 28 items that can be done with pen and paper, or online. It's divided into 2 subscales, the activities-of-daily-living (ADL) and sports subscales.[1]
Patients are asked about their functional ability and how much difficulty do they have with their hip over the past weeks. The ADL subscale contained 19 items pertaining to basic daily activities, and the sports subscale contained 9 items pertaining to higher-level activities. HOS consist of 5 potential responses, ranging from “unable to do” to “no difficulty.” In the scoring responses were from 0 =“unable to do” to 5= “no difficulty”.
In addition, a response of “nonapplicable” was also added. This allows subjects to designate that something other than their hip problem limits their activity. This means that both missing responses and nonapplicable responses could not be scored.[1]
Score Interpretation[edit | edit source]
Validity and Reliability[edit | edit source]
The HOS have relatively high correlations with concurrent measures of physical function and relatively low correlations with concurrent measures of mental health.[1]
