What contextual features affect the outcome and sustainability of therapeutic patient education interventions?

BACKGROUND: Therapeutic patient education interventions are influenced by contextual factors. Therefore, describing the context is crucial to understanding how it can affect therapeutic patient education interventions and contribute to outcomes. We aimed to identify the contextual features that may affect the outcome and sustainability of therapeutic patient education interventions from a healthcare professional perspective. METHODS: Semi-structured individual interviews were conducted with healthcare professionals involved in 14 therapeutic patient education interventions covering different chronic conditions (e.g., kidney and cardiovascular diseases, chronic pain, diabetes, obesity). Interviews were recorded and fully transcribed. We followed a general inductive approach to identify themes from healthcare professionals' discourse to properly capture their perception. RESULTS: Saturation was achieved with 28 interviews with 20 nurses, 6 dieticians, one physiotherapist and one psychologist. The average therapeutic patient education experience was 7 years. Identified contextual features clustered in 5 main themes: 1) conditions for the development of the intervention (genesis of the program: Who and what prompted it?; supports; content development; legislative framework); 2) integration of the program (in the healthcare pathway or the environment, relationship with the institution or local environment); 3) teamwork cohesion, interaction and integration with the environment (exchanges, cohesion of the team); 4) sustainability of the program; and 5) patient and healthcare professional contextual factors. CONCLUSION: New insights into contextual features that may be involved in therapeutic patient education interventions are represented in a framework based on the Medical Research Council evaluation framework. These features need to be addressed in studies of therapeutic patient education interventions and could help healthcare professionals build more effective interventions within the context. However, describing a list of elements of the context is not enough; analyses should also focus on how the contextual elements might affect an intervention and how they interact.

Use of qualitative methods to optimize collaborative practices by highlighting differences in perceptions between professionals: an example of patient education.

Interprofessional working must be approached within health promotion interventions using systematic methods to identify areas of suboptimal collaboration. We designed a qualitative study with a purposive sample of seven French therapeutic patient education programs. Semi-structured individual interviews were conducted with 14 healthcare providers and seven clinician leaders (coordinators) involved in patient education. We used the same interview guide and thematic grid regardless of the professional's profile to compare their perceptions on elements affecting outcome, participation and sustainability of programs. Healthcare providers and coordinators addressed non-convergent issues at both ends of a continuum from a micro-level nested in the program delivery to a macro-level corresponding to the structured implementation and sustainability of the program. Meso-level issues featured convergent perspectives. Our methodology could be used at the level of health services in a health system to provide a complete recovery of stakeholders' perspectives (without "blind spots" from one stakeholder or another). In our study, we focused on patient education in the French health system and pointed out possible considerations to optimize the functioning of programs. Such considerations include specific training plan development, encouraging reflection on the content and use of initial assessment, leading sessions in pairs to save on work time, and communication on the ins and outs of organizational imperatives that require healthcare providers' contributions.

Patient Satisfaction and Perspectives on Self-Management Education Programs: A Qualitative Study.

Purpose: According to the Centre for Disease Control and Prevention, "Self-management education (SME) refers to programs that help people who have ongoing health conditions learn how to live life to the fullest". Most studies to date have focused on SME outcomes, such as the acquisition of predefined knowledge or skills or quality of life. However, no study has yet investigated patients' satisfaction with SMEs. The aim of the present study was therefore to explore participants' subjective appreciation of SME programs using qualitative methods and formulate propositions based on patients' preferences to improve ultimately clinical outcomes. Patients and Methods: Twenty-five participants from five French SME programs to conduct focus groups were recruited. An inductive approach using grounded theory as an overall methodology orientation for the thematic analysis process has been followed. The study was reported in compliance with the consolidated criteria for reporting qualitative research criteria (COREQ). Results: Patients expressed great satisfaction concerning the effective delivery of SME sessions. They appreciated the considerations for their concerns and needs, the adaptation of sessions' content to their interests and questions, and learning to take care of themselves. Moreover, patients had a positive opinion on the quality of their relationship with health care providers. However, the major point of improvement of SMEs was the opportunity to repeat the program if needed, as this opportunity was not offered. This consideration was particularly salient when patients did not consider themselves autonomous for disease management at the end of the program, ie, when they had low levels of perceived self-efficacy. Conclusion: While patients expressed great satisfaction regarding SME programs, our results suggest that some changes might be needed to make the endpoint of SME interventions coincide with the patient's perception of self-efficacy in disease self-management and ultimately improve clinical outcomes.

Healthcare providers perception of therapeutic patient education efficacy according to patient and healthcare provider characteristics.

OBJECTIVES: Therapeutic patient education improves numerous health and psychological outcomes in patients with chronic diseases. However, little is known about what makes a therapeutic patient education intervention more effective than another one. This study aims to identify in healthcare professionals the perceived determinants of therapeutic patient education efficacy at the individual level. METHODS: Semi-structured individual interviews have been conducted with healthcare professionals (HCP, n=28, including 20 nurses) involved in therapeutic patient education programs (n=14) covering various chronic conditions (kidney and cardiovascular diseases, chronic pain, diabetes, etc.). A thematic content analysis following an inductive approach was used (Nvivo.11 software). RESULTS: Five themes were retrieved for patient characteristics: understanding and education, personality, readiness and motivation, social environment, and misinformation and beliefs. Four themes were retrieved for healthcare professionals' characteristics: medical knowledge, appropriate attitude and relational skills, pedagogical skills, and training. DISCUSSION: Patient personality is rarely discussed in the literature. Patients who are introverted, lack curiosity, or are not compliant might benefit from specific therapeutic patient education practices or formats. All these potential determinants regarding patients and healthcare professionals should be routinely assessed in future studies about therapeutic patient education efficacy to understand precisely what makes an intervention successful.

Do Glucocorticoid Injections Increase the Risk of Knee Osteoarthritis Progression Over 5 Years?

OBJECTIVE: Recent findings have demonstrated that intraarticular (IA) glucocorticoid injections can be deleterious for knees with osteoarthritis (OA). This study was undertaken to assess, in a real-life setting, the risk of knee OA progression in patients who received IA glucocorticoid injections over a 5-year follow-up period. METHODS: We used marginal structural modeling with inverse probability of treatment weighting to determine the causal association between IA glucocorticoid injections and the 5-year risk of disease progression in patients with symptomatic knee OA from the Knee and Hip Osteoarthritis Long-term Assessment cohort. OA progression was defined as an incident total knee replacement (TKR) and/or radiographic worsening (Kellgren/Lawrence [K/L] grade or joint space narrowing [JSN]). We also examined these outcomes in knees that received IA hyaluronan (IAHA) injections. RESULTS: Among the 564 patients with knee OA included in the study sample, 51 (9.0%) and 99 (17.5%) received IA glucocorticoid or IAHA injections, respectively, and 414 (63.1%) did not receive any injection during follow-up. Compared to untreated knees, those treated with IA glucocorticoid injections had a similar risk of incident TKR (hazard ratio [HR] 0.92 [95% confidence interval (95% CI) 0.20, 4.14]; P = 0.91) or K/L grade worsening (HR 1.33 [95% CI 0.64, 2.79]; P = 0.44). IAHA injections had no effect on the risk of TKR (HR 0.81 [95% CI 0.14, 4.63]; P = 0.81) or K/L grade worsening (HR 1.36 [95% CI 0.85, 2.17]; P = 0.20). Similar results were obtained for JSN, and when TKR and radiographic outcomes were combined. CONCLUSION: In this study, IA glucocorticoid injections for symptomatic knee OA did not significantly increase the 5-year risk of incident TKR or radiographic worsening. These findings should be interpreted cautiously and replicated in other cohorts.

Characteristics of patients with knee and/or hip osteoarthritis undergoing spa treatment: the prospective KHOALA cohort study.

Knee and hip osteoarthritis (KHOA) are a source of functional impairment. With aging, the management of osteoarthritis (OA) is a major issue in the search for improved quality of life. Spa treatment provides short- and mid-term symptom relief without serious side effects. This study aimed to identify characteristics of patients with KHOA associated with use of spa treatment. The prospective KHOALA cohort included 878 adults aged 40 to 75 years with symptomatic KHOA. We separately analyzed knee and hip OA data and compared patients who never had spa treatment with those who had at least one or multiple treatments during 5 years of follow-up in terms of socio-demographic characteristics, clinical data, quality of life (OAKHQOL, SF-36), physical activity (MAQ), functional impairment (WOMAC), and health care consumption (pharmacological and non-pharmacological treatments). Factors associated with at least one or multiple spa treatments were evaluated with regression logistic models. In all, 607 (69.1%) patients had knee OA (KOA), 222 (25.3%) hip OA (HOA) and 49 (5.6%) both, 91 (13.9%) with KOA, and 33 (12.2%) with HOA had at least one spa treatment. In the KOA cohort, the probability of at least one, two, or three spa treatments was increased with older age (odds ratio = 1.6 [95% confidence interval 1.2-2.2], 1.8 [1.2-2.8], 2.4 [1.4-4.2], respectively), greater use of physiotherapy (OR = 3.9 [2.1-7.1], 2.7 [1.3-5.6], 2.5 [1.1-5.9]), having a prosthesis (OR = 2.1 [1.2-3.8], 2.2 [1.1-4.3], 2.5 [1.1-5.5]), and low MAQ score (OR = 0.7 [0.6-0.9], 0.7 [0.5-1.0], 0.7 [0.5-1.0]). In the HOA cohort, female sex was associated with at least one (OR = 3.0 [1.1-8.0]) or two (OR = 5.1 [1.2-22.5]) spa treatments. In this cohort of KHOA, repeated spa treatment over 5 years was strongly associated with older age, greater use of physiotherapy and presence of a prothesis with KOA and female sex with HOA. This study may help to better understand spa treatment determinants in OA.

Tailored patient therapeutic educational interventions: A patient-centred communication model.

BACKGROUND: Tailoring therapeutic education consists of adapting the intervention to patients' needs with the expectation that this individualization will improve the results of the intervention. Communication is the basis for any individualization process. To our knowledge, there is no guide or structured advice to help healthcare providers (HCPs) tailor patient education interventions. OBJECTIVES: We used a data-driven qualitative analysis to (1) investigate the reasons why HCPs tailor their educational interventions and (2) identify how this tailoring is effectively conducted. The perspective aimed to better understand how to individualize therapeutic patient education and to disentangle the different elements to set up studies to investigate the mechanisms and effects of individualization. DESIGN: Individual semistructured interviews with 28 HCPs involved in patient education were conducted. The present study complied with the COREQ criteria. RESULTS: Why individualization is necessary: participants outlined that the person must be thought of as unique and that therapeutic education should be adapted to the patient's personality and cognitive abilities. The first step in the individualization process was formalized by an initial patient assessment. Several informal practices were identified: if needed, giving an individual time or involving a specific professional; eliciting individual objectives; reinforcing the relationship by avoiding asymmetrical posture; focusing on patients' concerns; leading sessions in pairs; and making the patient the actor of decisions. CONCLUSION: From our thematic data analysis, a model for tailoring patient education interventions based on the Haes and Bensing medical communication framework is proposed. The present work paves the way for evaluation, then generation of recommendations and finally implementation of training for individualization in educational interventions. SHORT INFORMATIVE: Tailoring in therapeutic education consists of an adaptation to patients' needs. Communication is the basis for any individualization process. There is no model of patient-centred communication in educational interventions. From semistructured interviews with HCPs, we propose a patient-centred communication model for tailoring patient education intervention.

Association of Baseline Cardiovascular Diseases with 5-Year Knee and Hip Osteoarthritis Progression in Non-Obese Patients: Data from the KHOALA Cohort.

We aimed to explore the relationship between comorbidities and the structural progression in symptomatic knee and/or hip osteoarthritis (OA) patients. We analyzed the 5-year outcome of non-obese participants (body mass index (BMI) < 30 kg/m2) from the KHOALA cohort having symptomatic hip and/or knee OA (Kellgren and Lawrence (KL) ≥ 2). The primary endpoint was radiological progression, defined as ΔKL ≥ 1 of the target joint at 5 years. The secondary outcome was the incidence of total knee or hip replacement over 5 years. Dichotomous logistic regression models assessed the relationship of comorbidities with KL progression and joint replacement while controlling for gender, age and BMI. Data from 384 non-obese participants were analyzed, 151 with hip OA and 254 with knee OA. At 5 years, cardiovascular diseases (CVD) were significantly associated with the 5-year KL change in both knee (OR = 2.56 (1.14-5.78), p = 0.02) and hip OA (OR = 3.45 (1.06-11.17), p = 0.04). No significant relationship was found between any type of comorbidities and knee or hip arthroplasty. This 5-year association between CVD and radiological progression of knee and hip OA in non-obese participants argue for an integrated management of CVD in knee and hip OA non-obese patients.

Time to initiation of biologic disease-modifying antirheumatic drugs in the French cohort ESPOIR.

OBJECTIVE: To assess the time to initiation of biologic disease-modifying anti-rheumatic drugs (bDMARDs) in ESPOIR, the French cohort of patients with rheumatoid arthritis (RA), and factors associated with the timing of bDMARD initiation. METHODS: In total, 658 patients with early RA satisfying the 2010 ACR/EULAR criteria were included between 2003 and 2005 and followed annually for 10 years (end of follow up: 2013-2015). The timing of bDMARD introduction and predictors of use were analysed by the Kaplan-Meier method based on Cox proportional-hazard models. RESULTS: Overall, 178 patients (31.0%, 95% confidence interval [27.0-34.7]) initiated a bDMARD during the 10-year follow-up, with a mean delay of 43.6 months. The penetration rate was higher during the first 2 years of follow-up (6% between the first and second year, approximately 3.3% each year between the second and seventh year, and<2.0% after the eighth year). The first-used bDMARD was etanercept for 72 patients and adalimumab for 71. On multivariate analysis, Disease Activity Score in 28 joints, radiologic progression and positivity for anti-citrullinated protein antibodies were significantly associated with rapid initiation of a bDMARD (P<0.0001), whereas older age at first joint pain was inversely associated (P<0.0001). CONCLUSIONS: Although access to bDMARDs is widespread in France, less than one third of patients with early RA in the ESPOIR cohort initiated a bDMARD over the 10-year follow-up. Poor prognostic factors for RA were associated with more rapid initiation, as expected.

Impact of smoking on femorotibial and hip osteoarthritis progression: 3-year follow-up data from the KHOALA cohort.

OBJECTIVES: To evaluate the clinical and structural impact of smoking on knee and hip osteoarthritis at baseline and after 3years. METHODS: Observational data on the progressive effects of smoking at baseline and after 3years were collected from The Knee and Hip Osteoarthritis Long-Term Assessment cohort comprising a French population of patients aged 40-75years with symptomatic lower limb osteoarthritis. Clinical (the Western Ontario and McMaster Universities Arthritis Index and Harris scores) and structural (radiography for osteophyte detection and joint-space narrowing assessment) were conducted. The tobacco usage categories were 'never smoker', 'former smoker', and 'current smoker'. RESULTS: Of the 873 subjects included, 215 (25%) were former smokers and 119 (14%) were current smokers. Multivariate analyses revealed that former and current smokers had fewer knee osteophytes in the medial compartment at baseline (odds ratio [OR]=0.64 [0.41-0.99] and 0.63 [0.36-1.11], respectively), lower osteophyte development in the lateral condyle after 3years (OR=011 [0.03-0.45] and 0.15 [0.03-0.97]), and lower osteophyte development in the lateral tibial plateau after 3years (OR=0.22 [0.06-0.75] and 0.68 [0.14-3.35]). Higher tobacco consumption and longer duration of consumption were significantly associated with fewer knee osteophytes at baseline and lower osteophyte development at 3years. CONCLUSION: Although cigarette smoking did not influence knee function, pain, or the need for replacement surgery, current and former smokers developed fewer osteophytes. This relationship may be linked to the quantity and duration of consumption. Our results provide further insight into the smoking-related pathophysiology of osteoarthritis.

Patient Global Assessment of Disease Activity and Radiographic Progression in Early Arthritis: Three-Year Results From the ESPOIR Cohort.

OBJECTIVE: To determine whether patient global assessment of disease activity (PtGA) over the first year of disease course, as part of a Boolean-based definition of remission and considered individually, had a significant relationship with structural progression over 3 years in patients with early arthritis. METHODS: We conducted a prospective, observational study using ESPOIR (Étude et Suivi des Polyarthrites Indifférenciées Récentes) cohort data. Remission states were defined as 1) 4-variable remission, which included a tender joint count in 28 joints, a swollen joint count in 28 joints (SJC28), a C-reactive protein (CRP; mg/dl) level, and PtGA (scored 0-10, all scores of ≤1); 2) PtGA near remission, which included the same parameters as 4-variable remission with only PtGA >1 (of a maximum possible score of 10); 3) 3-variable remission (sum of the proportion of patients in 4-variable remission and the proportion of patients in PtGA near remission); or 4) nonremission. The strictest status satisfied both at 6 and 12 months was considered. Radiographic progression was determined as a change of ≥5 points in the total Sharp/van der Heijde score (ΔSHS) from baseline to 3 years. The predictive capacities for radiographic damage of different remission definitions were assessed by odds ratio (OR). The association between each individual component of remission with ΔSHS was tested through multivariate linear regression analyses. RESULTS: Among 520 patients, 7% achieved 4-variable remission and 12% achieved PtGA near remission. Radiographic progression was observed in 29% of patients who achieved 4-variable remission (OR versus nonremission; OR 0.32 [95% confidence interval (95% CI) 0.15, 0.68]) and in 45% of patients with PtGA near remission (OR 0.65 [95% CI 0.38, 1.11]); the comparison was not statistically different (OR 0.49 [95% CI 0.20, 1.18]). In 3-variable remission, radiographic progression was observed in 39%. Of the individual components, only the SJC28 and CRP level were associated with radiographic progression. CONCLUSION: All definitions of remission led to low structural degradation in early arthritis, and 4-variable remission led to less radiographic progression than PtGA near remission, but without a statistically significant difference. Both 4-variable remission and 3-variable remission appear to be useful targets when aiming for structural nonprogression.

Patients and spouses coping with inflammatory arthritis: Impact of communication and spousal perceived social support and burden.

OBJECTIVES: To guide Therapeutic Patient Education (TPE) programs to improve patients' and spouses' perceived health, we aimed to analyze the effect of the spouse health state and patient-spouse relationship on functional impairment, mental health and self-efficacy of patients with RA or SpA. METHODS: In this observational cross-sectional study, inclusion criteria were age≥18years and diagnosis of RA or SpA. The outcome criteria were functional impairment and mental health measured by the Medical Outcomes Study Short-Form 12-item version (SF-12-MCS); mental health measured by the General Health Questionnaire (GHQ-12); and self-efficacy by the General Self-Efficacy Scale (GSE Scale). Caregiver-patient relationship was assessed by the Personal Assessment of Intimacy in Relationships (PAIR) questionnaire and the Dyadic Adjustment Scale (DAS); social support by the Social Support Questionnaire-6 and spousal burden by the Zarit questionnaire. RESULTS: A total of 88 patient-spouse couples were included. Patients were mostly female (n=68, 77%), with mean age 59 (SD 12.6) years; 69% had RA. On bivariate analyses, only spousal burden was associated with patients' functional impairment. Patients' mental health was associated with satisfaction with social support and the dyad relationship. Self-efficacy of patients was associated with spousal burden, satisfaction with social support, spousal anxiety/depression and the dyad relationship. On multivariate analysis, improved mental health and perceived self-efficacy of patients were associated with spousal satisfaction with social support (Beta=0.8, P=0.1 with GHQ-12) good communication in the couple (Beta=0.5, P=0.04 with SF-12-MCS and Beta=0.4, P=0.04 with GSE Scale) and low spousal-assessed burden (Beta=-0.2, P=0.003 with GSE Scale). CONCLUSION: This study has identified potential focus for intervention. It has highlighted the importance of recognizing the role of couple communication (experiencing an open and fluent exchange of ideas) in the patient's mental health and self-efficacy but also perceived satisfaction with social support of both members of the couple on the patient's mental health.

Pain in women with knee and/or hip osteoarthritis is related to systemic inflammation and to adipose tissue dysfunction: Cross-sectional results of the KHOALA cohort.

BACKGROUND: Considering the role of metabolic diseases in osteoarthritis (OA), we investigated whether biomarkers of adipose tissue dysfunction could be associated with OA-related pain. DESIGN: We cross-sectionally analyzed patients with knee and/or hip OA at inclusion in the KHOALA cohort. We used visual analogic scale (VAS) for pain, the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Osteoarthritis Knee and Hip Quality of Life (OAKHQOL) pain subscores. At inclusion, we measured ultra-sensitive CRP (usCRP), leptin and adiponectin for calculation of leptin:adiponectin ratio (LAR), a marker of adipose tissue dysfunction associated with central adiposity, high-molecular-weight adiponectin, visfatin and apolipoproteins. Univariate and multivariable analyses using stepwise linear regression models were performed to search for correlation between pain assessments and these biomarkers, with systematic adjustment on age. RESULTS: In 596 women with hip and/or knee OA, multivariable analyses indicated that higher pain intensity was associated with higher LAR (VAS pain: ß=0.49; p = 0.0001, OAKHQOL pain: ß=-0.46; p = 0.0002, WOMAC pain: ß=0.30; p = 0.001) in the whole group as well as in hip or knee OA patients considered separately. Pain intensity correlated also with usCRP level (VAS pain: ß= 0.27; p = 0.02, OAKHQOL pain: ß =-0.30; p = 0.01) and Kellgren-Lawrence score. In 267 men, no correlation between biomarkers and pain was found. CONCLUSION: Serum LAR and usCRP level are associated with pain level, independently of radiographic structural severity in women with hip and/or knee OA, emphasizing the role of adipose tissue dysfunction and of meta-inflammation in pain experience in the female population.

Recommendations of the French Society of Rheumatology on pharmacological treatment of knee osteoarthritis.

OBJECTIVES: To establish recommendations for pharmacological treatment of knee osteoarthritis specific to France. METHODS: On behalf of the French Society of Rheumatology (SFR), a bibliography group analyzed the literature on the efficacy and safety of each pharmacological treatment for knee osteoarthritis. This group joined a multidisciplinary working group to draw up recommendations. Strength of recommendation and quality of evidence level were assigned to each recommendation. A review committee gave its level of agreement. RESULTS: Five general principles were established: 1) need to combine pharmacological and non-pharmacological treatments, 2) personalization of treatment, 3) symptomatic and/or functional aim of pharmacological treatments, 4) need to regularly re-assess the treatments and 5) discussion about arthroplasty if medical treatment fails. Six recommendations involved oral treatments: 1) paracetamol should not necessarily be prescribed systematically and/or continuously, 2) NSAIDs, possibly as first-line, 3) weak opioids, 4) strong opioids, 5) symptomatic slow-acting drugs of osteoarthritis, and 6) duloxetine (off-label use). Two recommendations involved topical agents (NSAIDs and capsaicin<1%). Three recommendations involved intra-articular treatments: corticosteroid or hyaluronic acid injections that can be proposed to patients. The experts did not draw a conclusion about the benefits of platelet-rich plasma injections. CONCLUSION: These are the first recommendations of the SFR on the pharmacological treatment of knee osteoarthritis.

Spa therapy with physical rehabilitation is an alternative to usual spa therapy protocol in symptomatic knee osteoarthritis.

The objective of the study was to demonstrate the non-inferiority of low-frequency spa therapy combined with rehabilitation (Spa-rehab) versus standard spa therapy at 6 months for symptomatic knee osteoarthritis (KOA). A prospective, randomized, monocenter, non-inferiority trial with recruitment of community-based symptomatic KOA patients was performed. Standard spa therapy comprised standardized spa treatment, 6 days a week for 3 weeks, and Spa-rehab therapy comprised spa sessions, 3 days a week for 3 weeks, followed by a dedicated rehabilitation program, 3 days a week for 3 weeks. The primary endpoint was achieving at 6 months a minimal clinically important improvement (MCII) for pain on a visual analog scale and/or an MCII for function on the WOMAC index and no knee surgery (composite MCII). Secondary endpoints were composite MCII at 3 months and achieving a Patient Acceptable Symptom State (PASS) for pain and function at 3 and 6 months. Among 283 patients included, 145 were allocated to standard spa therapy and 138 to Spa-rehab therapy. We could not demonstrate the non-inferiority of Spa-rehab therapy for the primary endpoint: difference for responders - 0.08 [90% CI (- 0.18 to 0.02), p = 0.14]. However, the difference test between the groups was not significant (p = 0.18). Spa-rehab therapy was not inferior to standard spa therapy for the composite MCII at 3 months or the PASS at 3 and 6 months. Spa-rehab therapy can reasonably be proposed to patients with symptomatic KOA. This protocol may be more cost-effective than standard spa therapy and avoid absenteeism from work and accommodation costs for patients who live close to a centre.

Trajectory analysis combining pain and physical function in individuals with knee and hip osteoarthritis: results from the French KHOALA cohort.

OBJECTIVES: The aims of this study were to identify homogeneous subgroups of knee and/or hip OA patients with distinct trajectories of the combination of pain and physical function (PF) over time and to determine the baseline factors associated with these trajectories. METHODS: We used data from the Knee and Hip Osteoarthritis Long-term Assessment (KHOALA) cohort, a French population-based cohort of 878 patients with symptomatic knee and/or hip OA. Pain and PF were measured annually over 5 years with the Medical Outcomes Study Short Form 36 questionnaire. First, trajectory models were estimated with varying numbers of groups for each of the outcomes separately then fitted into a multi-trajectory model. We used multinomial logistic regression to determine the baseline characteristics associated with each trajectory. RESULTS: Univariate four-class models were identified as most appropriate for pain and PF. Comparison of separate trajectories showed that 41% of patients included in the severe functional limitations trajectory did not belong to the more severe pain trajectory (Cramér's V statistic = 0.45). Group-based multi-trajectory modelling revealed four distinct trajectories of pain and PF. On multivariate analyses, female sex, older age, high Kellgren grade, low physical activity intensity, low psychosocial distress score (high distress) and low vitality score were associated with the more severe symptoms trajectory. CONCLUSION: Over 5 years, we identified four distinct trajectories combining pain and PF. Management of weight, fatigue and psychosocial distress and the practice of physical activity seem important to maintain function and limit pain in patients with lower-limb OA.

Five-year Evolution Patterns of Physical Activity and Sedentary Behavior in Patients with Lower-limb Osteoarthritis and Their Sociodemographic and Clinical Correlates.

OBJECTIVE: The present study aimed to identify trajectories of physical activity (PA) components (frequency, duration, intensity, and type) and screen-based sedentary behavior (SB) as well as baseline predictors of each trajectory in patients with hip and/or knee osteoarthritis (OA). METHODS: We included 878 patients with a 5-year follow-up from the KHOALA cohort. PA and SB were measured by the Modifiable Activity Questionnaire. We used group-based trajectory analysis to identify the trajectories of PA components and screen-based SB, and multivariable logistic regression to determine predictors of the identified trajectories. RESULTS: Two groups of trajectories were identified for each PA component and 3 for SB. High and decreasing PA duration was associated with female sex (OR 0.3, 95% CI 0.1-0.5) as was low and stable, more so than high and decreasing prevalence of weight-bearing activities (OR 0.6, 95% CI 0.4-0.9). Patients with impaired patient-reported outcome measures and obese patients often featured low versus high and decreasing prevalence of weight-bearing activities. Predictors of moderate and high versus low and slightly increasing screen-based SB trajectories were male sex, age < 60 years, single status (OR 1.5, 95% CI 1.1-2.1), obesity (OR 2.1, 95% CI 1.4-3.1), smoking (OR 2.0, 95% CI 1.1-3.7), and less physical jobs. Predictors of moderate and high versus low screen-based SB trajectories were all sociodemographic: male sex, age < 60 years, single status, obesity, smoking, and less physical jobs. CONCLUSION: Sociodemographic and clinical predictors of trajectories vary between PA components; they are associated mainly with PA frequency and type. No clinical characteristics were associated with screen-based SB.

What Is Relatives' Role in Arthritis Management? A Qualitative Study of the Perceptions of Patient-Relative Dyads.

PURPOSE: The main aim of patient education is to maintain or improve quality of life. It is mostly focused on patients even if families might be included. The aim of this study was to explore patients' and relatives' perceptions and experiences about the role of relatives in disease management in chronic inflammatory arthritis in order to provide insight into how patient education programs might include relatives. METHODS: Individual semi-structured interviews were conducted with 20 patients (13 with polyarthritis; 7 with spondyloarthritis) and one of their relatives (N=40). A thematic analysis following an inductive approach was carried out using the QDA-Miner Software (inter-coder agreement 0.7). RESULTS: The analysis revealed three relevant themes. The first was their perception of relatives' general roles, which included technical skills, knowledge about the disease and interpersonal skills. The other two themes dealt with their specific relationship: the dyad relationship (including the usual relationship and in the context of the disease) and the help relationship (including practical assistance and emotional help). CONCLUSION: The results show the wide-ranging role of relatives in practical and emotional support, the complexity of patient-relative interactions regarding requests for help, their relationship and ability to share difficulties. This study gives indications about how to include relatives in TPE programs and emphasizes the importance of developing interventions for patient-relative dyads regarding the practical and emotional management of the disease, as well as interactions concerning help. Those interventions should enhance patients and relatives' quality of life.

Chondrocalcinosis of the Knee and the Risk of Osteoarthritis Progression: Data From the Knee and Hip Osteoarthritis Long-term Assessment Cohort.

OBJECTIVE: To assess the impact of knee chondrocalcinosis (CC) on the 5-year risk of joint replacement and disease progression in patients with knee osteoarthritis (OA). METHODS: Patients with symptomatic knee OA without previous total joint (knee or hip) replacement (TJR) were recruited from the Knee and Hip Osteoarthritis Long-term Assessment cohort. Cox proportional hazards regression and generalized estimating equation models were used to compare the time from inclusion or OA diagnosis to total knee replacement (TKR) or TJR between patients with and those without knee CC at inclusion. In patients without incident TKR, logistic regression was performed to examine the association between CC and radiographic progression (Kellgren/Lawrence [K/L] grade) or worsening of Western Ontario and McMaster Universities Arthritis Index (WOMAC) subscores for OA pain or function between years 0 and 5. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated. Analyses were adjusted for age, sex, body mass index, WOMAC subscores, and K/L grade. RESULTS: Among the 656 patients included, 93 (14.2%) had knee CC, and 91 (13.9%) underwent TKR during the follow-up. Risk of TKR was not affected by the presence of knee CC (HR 1.26 [95% CI 0.74-2.17]). Similar results were obtained for the risk of incident TJR. For patients without incident TKR, knee CC did not affect the risk of worsening of K/L grade (odds ratio [OR] 0.9 [95% CI 0.4-1.7]), WOMAC pain subscore (OR 1.1 [95% CI 0.7-1.4]), or WOMAC function subscore (OR 0.9 [95% CI 0.4-2.0]). CONCLUSION: In patients with symptomatic knee OA, the presence of knee CC did not affect the risk of arthroplasty or disease progression at 5 years.
