A scoping review of patient self-report measures of flare in knee and hip osteoarthritis (OA): A report from the OMERACT flares in OA working group. Semin Arthritis Rheum 2023; 63:152281. [PMID: 37948937 DOI: 10.1016/j.semarthrit.2023.152281] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 10/06/2023] [Accepted: 10/09/2023] [Indexed: 11/12/2023]
Abstract
PURPOSE We aimed to analyze the content validity/domain match and feasibility of self-report instruments that could measure flare in osteoarthritis (OA), by extending our 2017 literature review on the definition of flare in knee and hip OA. METHOD We searched PubMed (Medline), Web of Science and PsycInfo (Ebsco Host) databases for original articles reporting research about flare (or synonyms) in humans with knee and hip OA, between 2017 and 2023. Four experts worked independently, checking the records, and assessing content validity and feasibility, writing justification for exclusion. RESULTS At literature review phase, 575 papers were filtered. After experts' analysis, 59 studies were included, and 44 instruments associated with flare in OA were identified. Most were studies about pain in knee or hip OA (35 %), cultural adaptation of a measure (33 %) or studies investigating psychometric properties of full (16 %) or short form (4 %) instruments. The assessment of domain match and feasibility revealed that 15 instruments were assigned a label of 'yes' or 'uncertain' as to whether or not there was a good match with the domain concept or whether the instrument was considered feasible to use. DISCUSSION Most identified instruments considered different aspects of pain and the associated discomfort in performing daily activities but did not include the central aspects of flare in OA, i.e. the change of state, nor the additional Outcome Measures in Rheumatology (OMERACT) endorsed domains for OA flare namely stiffness, swelling, psychological aspects, impact of symptoms including fatigue and sleep disturbance. Although it is possible that the period specified to conduct this literature review may have led to some recognized instruments being excluded, this review demonstrates the need for the research community to reach consensus on the best way to measure self-reported flares in future clinical trials and observational studies.

Virtual performance measure in osteoarthritis: An innovative transformation of patient care. OSTEOARTHRITIS AND CARTILAGE OPEN 2023; 5:100410. [PMID: 37829082 PMCID: PMC10565872 DOI: 10.1016/j.ocarto.2023.100410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 09/19/2023] [Indexed: 10/14/2023] Open
Abstract
Objectives The purpose of this study was to develop and establish reliability and validity of a virtual performance measure (VPM) score that encompassed 10 videos in patients with osteoarthritis of the knee joint. Patients' experience and satisfaction were documented. Design Forty videos were chosen for 10 functional tasks, with four videos showing increasing difficulty for each task. Patients were requested to choose the video that best reflected their own situation. Clinical and radiological findings and self-report and performance measures were completed. Results Data of 100 patients, 70 (70%) females, mean age: 65 ± 9 were examined. The Cronbach's alpha coefficient that examined internal consistency of the VPM score was 0.92. The intraclass correlation value of 0.82 was obtained for test-retest reliability. Factor analysis showed three distinct domains. There was moderate correlations between the VPM score and the self-report and actual performance measures ranging from r = 0.46 to 0.66. The VPM summated score of 10 activities was able to differentiate between candidates and non-candidates for knee arthroplasty, with the area under the curve value of 0.90 indicating excellent predictive validity. The overall patient experience and satisfaction was positive with 67% of participants feeling that virtual care could have an impact on minimizing physical presence in the clinic or hospital. Conclusions The VPM is a reliable and valid outcome measure in patients with osteoarthritis of the knee joint. This digital tool has the potential to transform osteoarthritis care by providing a valid remote measurement of real-life functional limitations and reduce the burden of time consuming in-person tests.

Abstract
OBJECTIVES To systematically review and provide estimates of the minimal important change (MIC) and difference (MID) for outcome tools in people with knee osteoarthritis (OA) after non-surgical interventions. Design A systematic review. DATA SOURCES MEDLINE, CINAHL, Web of Science, Scopus and Cochrane databases were searched up to 21 September 2021. ELIGIBILITY CRITERIA We included studies that calculated MIC and MID using any calculation method including anchor, consensus and distribution methods, for any knee OA outcome tool after non-surgical interventions. DATA EXTRACTION AND SYNTHESIS We extracted reported MIC, MID and minimum detectable change (MDC) estimates. We used quality assessment tools appropriate to the studies' methods to screen out low-quality studies. Values were combined to produce a median and range, for each method. RESULTS Forty-eight studies were eligible (anchor-k=12, consensus-k=1 and distribution-k=35). MIC values for 13 outcome tools including Knee injury and Osteoarthritis Outcome Score (KOOS)-pain, activities of daily living (ADL), quality of life (QOL) and Western Ontario and McMaster Universities Arthritis Index (WOMAC)-function were estimated using 5 high-quality anchor studies. MID values for 23 tools including KOOS-pain, ADL, QOL and WOMAC-function, stiffness and total were estimated using 6 high-quality anchor studies. One moderate quality consensus study reported MIC for pain, function and global assessment. MDC values from distribution method estimates for 126 tools including KOOS-QOL and WOMAC-total were estimated using 38 good-to-fair-quality studies. CONCLUSION Median MIC, MID and MDC estimates were reported for outcome tools in people with knee OA after non-surgical interventions. The results of this review clarify the current understanding of MIC, MID and MDC in the knee OA population. However, some estimates suggest considerable heterogeneity and require careful interpretation. PROSPERO REGISTRATION NUMBER CRD42020215952.

Abstract
INTRODUCTION The Healthy Ageing and Intellectual Disability (HA-ID) study is a prospective multicentre cohort study in the Netherlands that started in 2008, including 1050 older adults (aged ≥50) with intellectual disabilities (ID). The study is designed to learn more about the health and health risks of this group as they age. Compared with the amount of research in the general population, epidemiological research into the health of older adults with ID is still in its infancy. Longitudinal data about the health of this vulnerable and relatively unhealthy group are needed so that policy and care can be prioritised and for guiding clinical decision making about screening, prevention and treatment to improve healthy ageing. METHODS AND ANALYSIS This article presents a summary of the previous findings of the HA-ID study and describes the design of the 10-year follow-up in which a wide range of health data will be collected within five research themes: (1) cardiovascular disease; (2) physical activity, fitness and musculoskeletal disorders; (3) psychological problems and psychiatric disorders; (4) nutrition and nutritional state; and (5) frailty. ETHICS AND DISSEMINATION Ethical approval for the 10-year follow-up measurements of the HA-ID study has been obtained from the Medical Ethics Review Committee of the Erasmus MC, University Medical Centre Rotterdam (MEC-2019-0562). TRIAL REGISTRATION NUMBER This cohort study is registered in the Dutch Trial Register (NTR number NL8564) and has been conducted according to the principles of the Declaration of Helsinki.

Cross-cultural validity of the Animated Activity Questionnaire for patients with hip and knee osteoarthritis: a comparison between the Netherlands and Brazil. Braz J Phys Ther 2021; 25:767-774. [PMID: 34247947 DOI: 10.1016/j.bjpt.2021.06.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 04/30/2021] [Accepted: 06/08/2021] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND The Animated Activity Questionnaire (AAQ) was developed in the Netherlands to assess activity limitations in individuals with hip/knee osteoarthritis (HKOA). The AAQ is easy to implement and minimizes the disadvantages of questionnaires and performance-based tests by closely mimicking real-life situations. The AAQ has already been cross-culturally validated in six other countries. OBJECTIVE To assess the cross-cultural validity, the construct validity, the reliability of the AAQ in a Brazilian sample of individuals with HKOA, and the influence of formal education on the construct validity of the AAQ. METHODS The Brazilian sample (N = 200), mean age 64.4 years, completed the AAQ and the Western Ontario and McMaster Universities Index (WOMAC). A subgroup of participants performed physical function tests and completed the AAQ twice with a one-week interval. The Dutch sample (N = 279) was included to examine Differential Item Functioning (DIF) between the scores obtained in the Netherlands and Brazil. For this purpose, ordinal regression analyses were used to evaluate whether individuals with the same level of activity limitations from the two countries (the Dutch as the reference group) scored similarly in each AAQ item. To evaluate the construct validity, correlation coefficients were calculated between the AAQ, the WOMAC domains, and the performance-based tests. To evaluate reliability, the Cronbach's alpha coefficient, the intraclass correlation coefficient, and the standard error of measurement (SEM) were calculated. RESULTS The AAQ showed significant correlations with all the WOMAC domains and performance-based tests (rho=0.46-0.77). The AAQ showed high internal consistency (Cronbach's alpha=0.94), excellent test-retest reliability (ICC2,1 = 0.98), and small SEM (2.25). Comparing to the scores from the Netherlands, the AAQ showed DIF in two items, however, they did not impact on the total AAQ score (rho=0.99). CONCLUSION Overall, the AAQ showed adequate cross-cultural validity, construct validity, and reliability, which enables its use in Brazil and international/multicenter studies.

Abstract
Background Physiotherapy is a proven effective treatment strategy after total knee and hip arthroplasty (TKA/THA), however there is considerable practice variation regarding its timing, content and duration. This study aims to compare the (cost-) effectiveness of a standardized, treat-to-target postoperative physiotherapy strategy with usual postoperative care. Methods Using a cluster randomized study design, consecutive patients scheduled for a primary TKA/THA in 18 hospitals in the Netherlands will be assigned to the treat-to-target physio therapy strategy or usual postoperative care. With the treat-to-target strategy a standardized, individually tailored, exercise program is aimed at the attainment of specific functional milestones. Assessments are done at baseline, 6 weeks and 3, 6, 9 and 12 months follow up. The primary outcome will be the Knee injury / Hip disability and Osteoarthritis Outcome Score - Physical Function Short Form (KOOS-PS / HOOS-PS) at 3 months follow up. Secondary outcomes are the numeric rating scale for pain, the Oxford Knee and Hip Scores, performance-based test and the EuroQol 5D-5L for quality of life. Healthcare use, productivity and satisfaction with postoperative care are measured by means of questionnaires. In total, 624 patients will be needed of which 312 TKA and 312 THA patients. Discussion The study will provide evidence concerning the (cost-) effectiveness of the treat-to-target postoperative physiotherapy treatment compared to usual postoperative care. The results of this study will address an important evidence gap and will have a significant impact in daily practice of the physio therapist.

Abstract
Background The aim of this study was to explore the expression of miR-140 and miR-199 in synovia of patients with knee osteoarthritis (KOA) and its correlation with the progression of this disease. We used the Kellgren and Lawrence grading (KLG) system. Material/Methods There were 110 patients with early (KLG <2), middle (KLG=2) and late (KLG >2) stage KOA and 60 healthy individuals (control) included in this study. Results The relative expression levels of miR-140 (1.07±0.091) and miR-199 (1.03±0.110) in synovia of the control group were higher than those of KOA groups (0.511±0.130, 0.298±0.168) and the difference exhibited statistical significance (P<0.01). Expression of miR-140 in the middle and the late stage KOA groups (0.322±0.118 and 0.110±0.088 respectively) were 58.80% and 81.29% lower, respectively, compared to the early stage KOA group (0.588±0.172), which was significant (P<0.05). Expression of miR-199 in the middle and the late stage KOA groups (0.210±0.124 and 0.056±0.068 respectively) were 39.41% (P<0.05) and 83.72% (P<0.01) respectively lower than that in the early KOA group (0.344±0.147). The severity of OA was significantly negatively correlated with the expressions of miR-140 and miR-199 (r=−0.859, P<0.05; r=−0.724, P<0.001 respectively). Matrix metalloproteinase (MMP)-3 levels of the early stage, middle stage and late stage KOA groups were 1.320±0.118, 1.488±0.210, and 1.955±0.023 respectively; and IL-1β mRNA was 1.401±0.204, 1.522±0.210, and 1.889±0.217 respectively, which were obviously higher than those in the control group (1.020±0.085), (P<0.05). Conclusions Expression levels of miR-140 and miR-199 in synovia might act as an early diagnostic marker for KOA. These expression levels might also act as indicators of OA progression to some extent.

Responsiveness and interpretability of the Animated Activity Questionnaire for assessing activity limitations of patients with hip or knee osteoarthritis. Musculoskeletal Care 2019; 17:327-334. [PMID: 31402572 DOI: 10.1002/msc.1418] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Revised: 06/18/2019] [Accepted: 06/20/2019] [Indexed: 06/10/2023]
Abstract
PURPOSE The aim of the study was to determine the responsiveness and interpretability of the Animated Activity Questionnaire (AAQ), an online questionnaire in which osteoarthritis patients select animations that best match their performance of daily activities. METHODS A longitudinal study was carried out, in which 94 patients with hip or knee osteoarthritis were assessed at baseline, and 3 and 6 months after treatment (conservative and surgical). Responsiveness was assessed by means of testing hypotheses about expected correlations between change in AAQ, a Global Rating Scale of change (GRS) and change in the Activities of Daily Living subscale of the Hip disability or Knee injury and Osteoarthritis Outcome Score (H/KOOS), and a combination of performance-based tests (the 30 s chair-stand test, the timed up-and-go test and the nine-step stair climbing test). The minimal important change (MIC) was estimated by means of the receiving operating characteristics (ROC) method. RESULTS The correlations of the AAQ with the H/KOOS were as expected, but other correlations were lower than anticipated. The area under the ROC curve was 0.74 at 6 months. At 3 months' follow-up, the correlations were too low to calculate a MIC. A total of 20% of the results at 3 months and 80% of the results at 6 months were in accordance with the hypotheses. The MIC was 9 points at 6 months. CONCLUSIONS The AAQ was sufficiently responsive at the six-months follow-up, but not at the three-month follow-up. The MIC at the 6-month follow-up (9 points) was slightly lower than the smallest detectable change of 14 points found in a previous study.
