How people with knee pain understand why their pain changes or remains the same over time: A qualitative study

Translation, Cross-Culture Adaptation and Measurement Properties of the Simplified Chinese Version of the Osteoarthritis Knowledge Scale

OBJECTIVE

The aim of this study was to culturally adapt the Osteoarthritis Knowledge Scale (OAKS) into a simplified Chinese version and to evaluate its measurement properties among Chinese-speaking populations.

METHODS

The OAKS scale was translated and cross-culturally adapted following COSMIN guidelines. A total of 368 participants were recruited, including individuals with knee or hip osteoarthritis (OA), healthcare professionals, and individuals without OA. The study evaluated the scale's internal consistency, test-retest reliability, and factor structure using Exploratory Factor Analysis (EFA).

RESULTS

The translated OAKS scale demonstrated acceptable levels of reliability across different groups. Cronbach's alpha for the KOAKS was 0.70 overall, with subgroup values ranging from 0.70 to 0.71. For the HOAKS, Cronbach's alpha was 0.77 overall, with subgroup values ranging from 0.63 to 0.72. Test-retest reliability showed high Intraclass Correlation Coefficient (ICC) values for both scales (KOAKS: ICC = 0.960; HOAKS: ICC = 0.982). EFA revealed that the overall OAKS explained a substantial portion of the variance (60.51%), with KOAKS accounting for 59.35% and HOAKS accounting for 54.68% of the variance.

CONCLUSION

The simplified Chinese version of the OAKS is a reliable tool for assessing OA knowledge among Chinese-speaking patients, healthcare professionals, and the general public. The findings highlight the necessity for continuous improvement and adaptation of educational interventions to address specific knowledge gaps within the Chinese context.

Making sense of osteoarthritis: A narrative review

People make sense of osteoarthritis (OA) by drawing on information, beliefs, and knowledge. This narrative review summarises diverse qualitative and quantitative research investigating beliefs and knowledge about OA and the impact these have on behaviour and outcomes. It synthesises evidence and highlights key actions clinicians can take to support people to make sense of OA in helpful ways. Beliefs about OA inform the behaviour of those living with OA and the behaviour of clinicians caring for people with OA. Beliefs about OA often focus on joint degradation and inevitable progression. These impairment-focused fatalistic beliefs can result in reduced offer of, or engagement in, active management strategies. Alternative views focus on health as part of a dynamic ecosystem where people are healthy when they can participate in activities they value. These beliefs are associated with increased engagement in self-management and lifestyle-based interventions. Clinician actions that support people to make sense of OA ways that align with helpful behaviours and support participation in valued activities represent key opportunities to improve health and well-being.

The Difficulties of Managing Pain in People Living with Frailty: The Potential for Digital Phenotyping

Pain and frailty are closely linked. Chronic pain is a risk factor for frailty, and frailty is a risk factor for pain. People living with frailty also commonly have cognitive impairment, which can make assessment of pain and monitoring of pain management even more difficult. Pain may be sub-optimally treated in people living with frailty, people living with cognitive impairment and those with both these factors. Reasons for sub-optimal treatment in these groups are pharmacological (increased drug side effects, drug-drug interactions, polypharmacy), non-pharmacological (erroneous beliefs about pain, ageism, bidirectional communication challenges), logistical (difficulty in accessing primary care practitioners and unaffordable cost of drugs), and, particularly in cognitive impairment, related to communication difficulties. Thorough assessment and characterisation of pain, related sensations, and their functional, emotional, and behavioural consequences ("phenotyping") may help to enhance the assessment of pain, particularly in people with frailty and cognitive impairment, as this may help to identify who is most likely to respond to certain types of treatment. This paper discusses the potential role of "digital phenotyping" in the assessment and management of pain in people with frailty. Digital phenotyping is concerned with observable characteristics in digital form, such as those obtained from sensing-capable devices, and may provide novel and more informative data than existing clinical approaches regarding how pain manifests and how treatment strategies affect it. The processing of extensive digital and usual data may require powerful algorithms, but processing these data could lead to a better understanding of who is most likely to benefit from specific and targeted treatments.

Within-person change in patient-reported outcomes and their association with the wish to undergo joint surgery during a digital first-line intervention for osteoarthritis

AIM

To study the association between within-person changes in patient-reported outcomes (PROMs) and wish for joint surgery during participation in a digital first-line intervention comprising exercise and education for knee/hip osteoarthritis (OA).

METHODS

Retrospective observational registry study. Participants enrolled between June 1, 2018 and October 30, 2021, with follow-up data at three months (n = 13,961). We used asymmetric fixed effect (conditional) logistic regressions to study the association between change in wish to undergo surgery at last available time point (3, 6, 9, or 12 months) and improvement or worsening of PROMs pain (0-10), quality of life (QoL) (EQ5D-5L, 0.243-0.976), overall health (0-10), activity impairment (0-10), walking difficulties (yes/no), fear of movement (yes/no), and Knee/Hip injury and Osteoarthritis Outcome Score 12 Items (KOOS-12/HOOS-12, 0-100) function and QoL subscales.

RESULTS

The proportion of participants wishing to undergo surgery declined by 2% (95% CI: 1.9, 3.0), from 15.7% at the baseline to 13.3% at 3 months. Generally, improvements in PROMs were associated with reduced likelihood of wishing for surgery, while worsening was associated with increased likelihood. For pain, activity impairment EQ-5D and KOOS/HOOS QoL, a worsening led to a change in the probability of wish for surgery of larger absolute magnitude than an improvement in the same PROM.

CONCLUSIONS

Within-person improvements in PROMs are associated with reduced wish for surgery while worsenings with an increased wish for surgery. Larger improvements in PROMs may be needed to match the magnitude of the change in wish for surgery associated with a worsening in the same PROM.
