Evaluation of osteoarthritis knee and hip quality of life (OAKHQoL): adaptation and validation of the questionnaire in the Hungarian population

Abstract

Background: At least 17% of the population suffers from osteoarthritis (OA) in Hungary, according to the European Health Interview Survey. In Hungary, until now there was no OA-specific questionnaire available for the lower limb, in order to monitor the health-related quality of life (HRQoL). This gap gave the relevance of this research. The aim of the study was to perform the Hungarian cross-cultural adaptation and validation of the French-developed Osteoarthritis Knee and Hip Quality of Life (OAKHQoL) questionnaire. Methods: The five-step translation procedure of the original OAKHQoL was performed by the expert panel and the translators. The created Hungarian version (OAKHQoL-HUN) was tested in six different geographical areas of Hungary. The validity and the reliability of this adapted tool was analyzed by our research group. Results: A total of 99 patients completed the questionnaires (78 women and 21 men), with the average age of 66.6 years (standard deviation (SD) 12.1), living with OA for more than 10 years. Excellent internal consistency was observed in the following domains: physical activity (α = 0.93), mental health (α = 0.91) and pain (α = 0.89). Good correlation was determined between physical subscales ( r = 0.615–0.676) and mental subscales ( r = 0.633–0.643) compared to generic quality of life instruments (World Health Organization Quality of life – BREF questionnaire and EQ-5D-3L). Conclusion: The OAKHQoL-HUN is the first valid and reliable tool for measuring the Hungarian lower limb OA patients’ quality of life. Trial Registration: This study is registered (24950-3/2016/EKU) by the National Ethics Committee: the Hungarian Medical Research Council.

HURWA robotic-assisted total knee arthroplasty improves component positioning and alignment – A prospective randomized and multicenter study

“…KOA is one of the common joint diseases in the elderly and it is also the main cause of knee pain and functional limitation in the elderly [ 34 , 35 ]. TKA is a relative successful and effective method for relieving pain and functional recovery of end-stage knee osteoarthritis, which has been widely carried out worldwide [ 9 , 36 ].…”

“…In addition, Fekete et al, 2020 found that 15.15% of the patients had knee OA (15 out of 99 patients) for more than ten years. This study found that women are more affected by knee OA than men (12.4% and 9.9%, respectively) (Fekete et al, 2020). Furthermore, Horváth et al, 2011 found that 111 patients (out of 672, 16.5%, 70 women and 41 men) had radiographic knee OA and 2.9% of them had severe knee OA (K-L≥3) in the south-western part of Hungary (Horváth et al, 2011).…”

“…In Hungary, it was estimated that 17% of the Hungarian population had OA based on the European Health Interview Survey 2014 (Fekete et al, 2020). In addition, Fekete et al, 2020 found that 15.15% of the patients had knee OA (15 out of 99 patients) for more than ten years. This study found that women are more affected by knee OA than men (12.4% and 9.9%, respectively) (Fekete et al, 2020).…”

“…The core signs and symptoms of knee OA are pain during daily activities, low physical level, disabilities, and mortalities(Hawker et al, 2014, Felson, 2006, Glyn-Jones et al, 2015. In Hungary, the prevalence of advanced and severe knee OA is increasing yearly(Horváth et al, 2011, Fekete et al, 2020. Moreover, the quality of life Hungarian patients with knee OA was less than other European patients with knee OA which could be related to differences in culture, the provided health services, and duration of illness(Wilburn et al, 2017).…”
