The Hip Disability and Osteoarthritis Outcome Score (HOOS) is a validated measure for patients hip associated health assessment. It has frequently been used in patient cohorts with osteoarthritis undergoing total hip replacement but – as the authors recommend – the tool can also be applied to non-osteoarthritic patients. With 40 questions to answer, the questionnaire allows a detailed overview of different health and function dimensions such as pain, function in daily living and hip related quality of life.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

This questionnaire was developed as an instrument to assess patients\u2019 opinion about their hip and associated problems. It has most frequently been used in patient groups with hip osteoarthritis undergoing total hip replacement surgery but can also be applied to non-osteoarthritic patients.1<\/a>, 2<\/a>, 3<\/a><\/sup><\/sub><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

The 40 items must be answered by selecting 1 of 5 response options.<\/p>

The HOOS includes the domains pain, other symptoms, function in daily living (ADL), function in sport and recreation (Sport\/Rec) and hip related quality of life (QOL).<\/p>

According to the homepage a completion time of 10 minutes can be assumed.4<\/sup><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Scoring method<\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The results of the HOOS are represented by five domain scores. Each of the items is scored from 0 (no health problems) to 4 (severe health problems). Therefor the scoring of every single domain \u00a0(pain, other symptoms, function in daily living, function in sport and recreation, hip related QoL) gets done separately by summing the score of the items and dividing it by the number of questions. Afterwards the mean score is transformed to a 0-100 score. 50% of the items of one domain need to be answered to calculate a valid score.<\/p>

scoring example:<\/strong><\/p>

domain function, sports and recreational activities: 4 questions<\/p>

question 1: answer 2 (1 points)<\/p>

question 2: answer 4 (3 points)<\/p>

question 3: answer 4 (3 points)<\/p>

question 4: answer 3 (2 points)<\/p>

mean score = (1+3+3+2)\/4 = 2,25\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0<\/p>

transformation to 0-100 score:\u00a0 100-(2,25*100)\/4 = 43,75 = domain score<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Score interpretation<\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The higher the score, the better patients health!<\/strong><\/p>

A score of 0 is connected with extreme hip-related problems, a score of 100 represents no hip-related health restrictions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
