Abstract
BackgroundThe Hip disability and Osteoarthritis Outcome Score (HOOS) is a self-administered hip-specific questionnaire intended to evaluate symptoms and functional limitations, and it is commonly used to evaluate interventions in individuals with hip dysfunction or hip osteoarthritis. The HOOS consists of 43 questions in five subscales: Pain, Symptoms, Function in daily living, Function in sport and recreation and Hip-Related Quality of Life. This study aimed to establish population-based reference values for the HOOS and to describe the variation of hip-related symptoms in an adult population.MethodsThe HOOS questionnaire was mailed to 840 individuals aged 18–84 years randomly retrieved from a national population record for the Skåne region of Southern Sweden.ResultsThe overall response rate was 67%. Older women and men consistently reported more hip-related complaints than those younger. There were significant differences between the oldest and the youngest age groups in all five subscales in women and men.ConclusionsHip-related pain, symptoms, activity of daily life and quality of life varied with age and sex in this population-based cohort. Our findings show the importance of using age- and sex-matched reference values for evaluation of outcomes after interventions due to hip-related problems.
Highlights
The Hip disability and Osteoarthritis Outcome Score (HOOS) is a self-administered hip-specific questionnaire intended to evaluate symptoms and functional limitations, and it is commonly used to evaluate interventions in individuals with hip dysfunction or hip osteoarthritis
Multi-item disease-specific self-reported outcome measures have been recommended to assess the effect of interventions on hip injury and hip osteoarthritis (OA) [1]
The HOOS has been validated for short- and long-term follow-up studies of patients with primary OA assigned for total hip replacement (THR) [2, 5, 8]
Summary
The Hip disability and Osteoarthritis Outcome Score (HOOS) is a self-administered hip-specific questionnaire intended to evaluate symptoms and functional limitations, and it is commonly used to evaluate interventions in individuals with hip dysfunction or hip osteoarthritis. Multi-item disease-specific self-reported outcome measures have been recommended to assess the effect of interventions on hip injury and hip osteoarthritis (OA) [1]. The Hip disability and Osteoarthritis Outcome Score (HOOS) was established as an extension of The Western Ontario and McMaster Universities Arthritis Index (WOMAC) by adding new questions based on over one hundred interviews with individuals with hip disability [2,3,4]. When assessing individuals with hip OA the psychometric properties of the HOOS have shown adequate test-retest reliability, floor and ceiling effects, and construct validity. The HOOS has psychometric properties that enable researchers and clinicians to use it with confidence [5, 9,10,11]
