Editor's Notes
- #2: Good afternoon Ladies and Gentlmen. I will be reporting on the Reliability of the KOOS-PS in Video Format.
- #3: PROMS utilization has increased drastically in last decade and is now widely used by healthcare practitioners. It has been suspected that PROMs are not well understood in 3rd world countries. This could largely be due to Language and cultural barriers Here in South Africa there are 11 different National Languages, high levels of illiteracy and lower educational levels. Using a written English score is not always practical Can the use of a video demonstration overcome the language / cultural barrier and be just as effective?
- #4: We aim to test reliability of the new video version of the KOOS-PS
- #5: Conversion: Video demonstrations for each function were created and decided on by a panel of students. A Likert scale in the form of smiley faces was used as a measure Level of difficulty. Data Collection: Patients completed the following: Consent OKS WOMAC KOOS-PS Data Analysis: Reliability Internal Consistancy – Cronbach’s Coefficient
- #6: These are the video demonstrations for each of the KOOS-PS questions, with the Likert scale of difficulty in the form of Smiley faces (Happy – sad face representing No difficulty to Extremely Difficult) Video 1 represents “Rising from the bed” Video 2 represents “ Putting on socks” Video 3 represents “Rising from sitting” Video 4 represents “Bending to the floor” Video 5 represents “Twisting/Pivoting on Injured Knee” Video 6 represents “Kneeling” Video 7 represents “Squatting”
- #7: 70 Patients were recruited Average Age was 50 years 57,6% were Female and 42,4% were Male 57,1% had not finished school, 22,5% Finished School with no further education and 20,4% have completed Tertiary Education
- #8: Based on the preliminary results: Internal consistency received a Cronbachs Coefficient of 0,899, considered an excellent value The mean of the video score was 58,4% and the mean score for the KOOS-PS was 61,55%
- #9: In conclusion, the video score measured knee function consistently and reliably With a validated video score, there will be no need to translate original validated scores to other languages. A trend of discrepancy was found with patients of lower education, possibly indicating that the video score was easier to comprehend than the written version of the KOOS-PS Future research could investigate the comprehension of written scores vs. visual based scores and obtain a larger sample size to determine time efficiency between scores. THANK YOU.
