Measuring participation in people with spondyloarthritis using the social role participation questionnaire.

OBJECTIVES: People with spondyloarthritis (SpA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) have identified the importance of understanding how their disease and its treatment impacts on their social roles. This requires a reliable and valid standardised measure, and this study evaluates these measurement properties of the Social Role Participation Questionnaire (SRPQ). METHODS: 109 participants (44 with AS, 65 with PsA) completed questionnaires on demographics, participation measures (SRPQ, Keele Assessment of Participation (KAP), Late Life Disability Instrument (LLDI)), disease severity (physician global) and activity (pain, fatigue, Bath Ankylosing Spondylitis Disease Activity Index), psychological measures (depressive symptoms (Hospital Anxiety and Depression Scale), Illness Intrusiveness)) and function (Health Assessment Questionnaire, Bath Ankylosing Spondylitis Functional Index). After testing scaling properties, test-retest reliability of the SRPQ was evaluated using intraclass correlation coefficients (ICC) and hypotheses of construct validity were evaluated using correlation coefficients. RESULTS: Patients with AS had a mean age of 40 years and 65% were male, whereas patients with PsA had a mean age of 53 years and 63% were male. Although there were some differences between AS and PsA participants in their social role participation, scaling properties were good for both groups. ICCs were >0.90 for the satisfaction subscales of the SRPQ. For construct validity, SRPQ satisfaction subscales were moderately correlated with the KAP and LLDI (0.64-0.78), and less satisfaction was associated with higher disease severity and activity, more depressive symptoms, more illness intrusiveness and more disability (coefficients -0.67 to -0.88). CONCLUSION: Social role participation is an important concept for people with SpA, and the SRPQ is a reliable and valid measure for use with people with AS and PsA.

Development and Reliability of an Appropriateness and Prioritization Instrument for Eye Care Practice: A Modified Delphi Process.

Purpose: To modify the Western Canada Waiting List Project (WCWLP) cataract prioritization criteria into measurement instruments for assessing appropriateness and prioritization emphasizing health-related quality of life (HRQoL) and examining reliability.Methods: A modified Delphi process was conducted using two rounds of online surveys and a face-to-face meeting. A panel of eye care experts rated the relevancy of criteria on a 5-point scale. Patient narratives highlighted the patient experience. A G-theory framework was used to assess inter- and intra-rater agreement using the criteria.Results: Nine Ophthalmologists, three Optometrists, and one General Practitioner participated in the modified Delphi process. Consensus to include/exclude was reached on all criteria. Seventeen criteria were included and 16 were excluded. The most significant changes were related to the categorization of comorbidities and expansion of HRQoL questions. The overall reliability was good (ϕ = 0.852).Conclusion: The WCWLP was modified to include appropriateness and to better reflect HRQoL. Having achieved consensus and demonstrated reliability of the criteria, the next step is to estimate weights for criteria and to validate against patient health outcomes data.

Public opinion on community-based education and exercise programs for managing hip and knee osteoarthritis-like symptoms: results of a survey.

INTRODUCTION: In North America, delivery of targeted exercise and education programs by health professionals for people with hip and knee osteoarthritis (OA) poses challenges related to cost and access. Linking the wellness and health sectors could increase program availability. We evaluated if people with OA were willing to participate in programs delivered by trainers in community centers/gyms. METHODS: We conducted an online survey of the general public in Canada over a period of 2 months. Participants included those aged ≥30 years with self-reported chronic OA-like knee or hip pain. We evaluated access to community/fitness centers, exercise frequency, interest in attending an evidence-based program twice a week for 6 weeks, and willingness to pay. Analyses included descriptive statistics with 95% confidence intervals and chi-square tests to evaluate factors associated with willingness to attend the program. RESULTS: After removing duplicate records, 751 respondents completed the survey with 408 likely having hip and/or knee OA and never having received a joint replacement. These 408 respondents had an age range of 30 to ≥75 years and 86% were female. Of the 408, (63.7%) were between 45 and 64 years of age. Only two respondents reported that a community center was >1 hour away. One hundred and fifty-six (38%) reported a current membership, and 203 (50.4%) reported exercise 3 days/wk, 120 (29.8%) <3 days, and 80 (19.9%) reported no exercise. Two hundred and ninety-seven respondents (73.7%) were willing to attend a program, and, of these, 26% were willing to pay $100 Cdn or more. Age, sex, access to a community center/gym, current gym membership, and current frequency of exercise were not significantly associated with willingness to attend a program. CONCLUSION: Almost 75% of respondents with OA, despite one in three having a community center membership, were interested in attending a targeted program delivered in community/fitness centers. A program in the wellness sector may be a viable option to support people in managing their hip and or knee OA.

The influence of patient factors on patient-reported outcomes of orthopedic surgery involving implantable devices: a systematic review.

OBJECTIVES: Recent evidence suggests that patient factors can influence response to medical and surgical treatment and may play an under-recognized role in predicting treatment outcomes. However, the current state of knowledge concerning potential associations following orthopedic surgery in particular is unclear. The purpose of the present study was to systematically review current literature to investigate the currently known associations between pre-operative patient factors and patient-reported outcomes following orthopedic surgery. METHODS: A systematic review was performed of the PubMed database to identify original studies that investigated the relationships between one or more patient factors and patient-reported outcomes of primary orthopedic surgical procedures involving implantation of a medical device. A total of 10,174 records were identified, with 83 studies included in the final review. RESULTS: The most commonly assessed patient factors included age, sex, and body mass index (BMI), reported in 63%, 55%, and 48% of studies, respectively. The only other patient factors identified were socioeconomic status and race, both of which were assessed in a single study. Considerable heterogeneity was observed in the methods used to stratify subjects by patient factors, patient-reported outcome constructs assessed, and follow-up intervals. Only 10% of studies performed appropriate sample size or power calculations, only 51% used methodologies to control for potentially confounding factors, and 6% assessed responder status. Overall, variable and conflicting findings were seen. While female sex and increasing BMI did appear to be associated with worse absolute outcomes, these differences did not appear to be maintained when differences in baseline status were considered. No clear associations between age and outcomes were identified. CONCLUSIONS: The present understanding of these relationships between patient factors and patient-reported outcomes following orthopedic surgery is limited. There is a need for further studies using high-quality methodology, consistent stratification of participants based on patient factors, accepted patient-reported outcome constructs, and appropriate assessment of responder status.
