PATIENT-REPORTED OUTCOMES FOR JOINT REPLACEMENT SURGERY
KNEE INJURY OSTEOARTHRITIS OUTCOME SCORE (KOOS-JR)
KOOS, JR. has received a lot of interest from the orthopedic community as an efficient and reliable alternative to the longer Knee Injury Osteoarthritis Outcome Score (KOOS) reporting tool.
The widely used KOOS questionnaire measures joint-specific pain, physical function, and contains 42 questions. The KOOS JR. has just seven.
The questions in the KOOS, JR. are taken directly from its parent questionnaire and focus on the three categories: joint pain, stiffness and function in daily living.
By comparison, KOOS focuses on five categories: pain, function in daily living, function in sport and recreation, other symptoms, and knee-related quality of life.
The brevity of KOOS, JR. allows for faster completion and greater patient completion.
HIP OSTEOARTHRITIS OUTCOME SCORE (HOOS-JR)
The widely used HOOS questionnaire measures joint-specific pain and physical function, and contains 42 questions. By contrast, the HOOS JR. has six questions.
Questions in HOOS JR. are taken directly from the parent questionnaire and focus on the three categories: joint pain, stiffness and function in daily living instead of the five categories in the HOOS Survey: pain, function in daily living, function in sport and recreation, other symptoms, and knee-related quality of life.
In the HOOS JR. questionnaire, patients rate each activity by indicating the amount of pain or disability they experience while carrying them out. Raw scores are added up and then converted to an interval score (0-100) using an interval table. The final interval score represents a patients total joint disability where 0 corresponds to total joint disability and 100 is perfect joint health.
The brevity of the HOOS, JR. survey allows for faster completion and greater patient engagement.
As part of the Patient-Reported Outcomes Measurement Information System (PROMIS) created in 2004, The PROMIS Global-10 is a publicly available global health assessment tool that allows measurements of symptoms, functioning, and healthcare-related quality of life (HRQoL) for a wide variety of chronic diseases and conditions.
The PROMIS Global-10 short form consists of 10 items that assess general domains of health and functioning including overall physical health, mental health, social health, pain, fatigue, and overall perceived quality of life.
The 10 questions of the Global-10 have largely been adapted from other frequently used “legacy” measures such as the SF-36 and EQ-5D.
