RESUMO

INTRODUCTION: Through interviews with 148 older persons from four countries and in four languages, the content for a 17-item measure of active living was developed. The purpose of this paper is to present further evidence of the extent to which this new measure, Older Persons Active Living (OPAL), is "fit-for-purpose" for measuring the extent of active living at one point in time. METHODS: A cross-sectional study was carried out on a population aged 65 + and living independently, drawn from a participant panel, HostedinCanada, sampling people from Canada, United States, United Kingdom, and Netherlands. The survey instrument comprised the OPAL questionnaire rated on importance and frequency, sociodemographics, and information on physical and mental function. The argument-based approach to validity framed the analyses. Logistic regression, structural equation modeling, ordinary least-squares regression, and correlation were used to generate estimates for parameters underpinning validity evidence. RESULTS: A total of 1612 people completed the survey, 100 to 400 people across the 6 country-language strata. The proportion of people rating the items as extremely or quite important ranged from 60 to 90%, with no important differences between men and women and few differences between strata. A single-factor structure was supported. The ordinality of the response options justified an additive total score yielding a near normal distribution (mean: 33.1; SD: 11.5; range 0-51). Correlations with other measures of converging constructs were of moderate strength (~ 0.50), and differences across groups known to affect functioning and health were observed, suggesting a Miminal Important Difference (MID) of 6 out of 51. CONCLUSION: The results of this study provide evidence that the 17-item OPAL measure is fit for the purpose of estimating the extent to which older persons are living actively at one point in time.

RESUMO

AIMS: Many older persons do not think of themselves as "patients" but as persons wishing to live as actively as possible for as long as possible. However, most health-related quality of life (HRQL) measures were developed for use with clinical populations. The aim of this project was to fill that gap and to develop, for international use, a measure of what matters to older persons as they age and seek to remain as active as possible, Older Persons for Active Living (OPAL). METHODS: For content development, interviews about active living were conducted with older persons from Canada, USA, UK, and the Netherlands in English, French, Spanish and Dutch, respectively with subsequent thematic analysis and harmonization. RESULTS: Analyses of transcripts from 148 older persons revealed that active living was a "way of being" and not merely doing activities. Saturation was reached and a total of 59 content areas were identified. After grouping similar "ways" together and after conducting a consensus rating of importance, 19 unique and important "ways" remained. In some languages, formulating was challenging for three of the 19, resulting in changes to two English words and dropping two other words, yielding a final list of 17 "ways of being" with harmonized wording in 4 languages. CONCLUSION: This study underscores the significance of listening to older adults and highlights the importance of considering linguistic and cultural nuances in measure development.

RESUMO

PURPOSE: To identify the contexts in which goal setting has been used in chronic disease management interventions and to estimate the magnitude of its effect on improvement of health outcomes. METHODS: The strength of evidence and extent of potential bias in the published systematic reviews of goal setting interventions in chronic conditions were summarized using AMSTAR2 quality appraisal tool, number of participants, 95% prediction intervals, and between-study heterogeneity. Components of goal setting interventions were also extracted. RESULTS: Nine publications and 35 meta-analysis models were identified, investigating 25 health outcomes. Of the 35 meta-analyses, none found strong evidence and three provided some suggestive evidence on symptom reduction and perceived well-being. There was weak evidence for effects on eight health outcomes (HbA1c, self-efficacy, depression, anxiety, distress, medication adherence, health-related quality of life and physical activity), with the rest classified as non-significant. Half of the meta-analyses had high level of heterogeneity. CONCLUSION: Goal setting by itself affects outcomes of chronic diseases only to a small degree. This is not unexpected finding as changing outcomes in chronic diseases requires a complex and individualized approach. Implementing goal setting in a standardized way in the management of chronic conditions would seem to be a way forward.IMPLICATIONS FOR REHABILITATIONThe link between goal setting and health outcomes seems to be weak.Some levels of positive behavioural change could be of benefits to patients as seen by improved self-efficacy, patients' satisfaction and overall quality of life.Systematic and consistent application of personalized goal-oriented interventions considering patient's readiness to change could better predict improved outcomes.Incorporation of various goal setting components while actively engaging patient and/or their care givers in the process could appraise how goal setting could help with challenges in faced by people living with chronic conditions in different areas.

RESUMO

INTRODUCTION: Soft-tissue sarcoma (STS) is a rare cancer of the connective tissues requiring invasive treatment. Due to the complexity of treatment, STS patients experience more functional impairment and disability than other oncologic populations. Given that extant literature is unclear and exclusively focused on physical function, the objectives of this study were to use the Wilson-Cleary Model of HRQL to evaluate the extent to which biological function (tumor site, depth and size), symptoms (fatigue, pain, anxiety/depression), and functional status are associated with the health perceptions of soft-tissue sarcoma patients 12 months post-op. METHODS: Data were drawn from an inception cohort study at the McGill University Health Centre. Inclusion criteria included 18 years of age and a biopsy-confirmed diagnosis of STS. Those with evidence of metastasis at diagnosis or less than 12 months of follow-up were excluded. Statistical analyses included T-tests, Pearson correlations, and multiple linear regression. RESULTS: 331 patients were included (185 males, 146 females) with mean (SD) ages of 56 (17). Significantly more females reported pain and anxiety/depression. Self-reported function was significantly higher in males. Overall, the regression model explained 53 % of the variance in health perceptions in males, and 48 % in females. Only self-reported function was significantly associated with health perceptions in males (B = 0.34) and females (B = 0.48). Further, compared to females without pain, females with pain perceived their health as significantly worse. CONCLUSION: Evaluating health perceptions with a multidimensional lens revealed new information about the STS patient experience. Findings suggest that key targets include routine psychosocial distress monitoring and addressing rectifiable disability-related barriers promptly.

RESUMO

BACKGROUND: Rehabilitation is the mainstay of management for people with disabilities of neurological origin to maximize function and reduce disability. Access to in-patient rehabilitation is usually reserved for people after crises or those who are discharged from acute care such as in stroke or trauma. Access to people with Multiple Sclerosis (MS) differs across countries and unknown for Canada. With the progression of MS, quality of life (QOL) becomes more closely coupled with independence and hence timely access to rehabilitation is important. The objectives of this paper are (i) to characterize the disability profiles of people with MS admitted to in-patient rehabilitation in Canada; and (ii) to estimate the extent to which disability profiles differ from admission to discharge. METHODS: A longitudinal study of a rehabilitation admission-to-discharge cohort of 3500 people with MS was conducting using latent class analysis on the five Functional Independence Measure (FIM) subscales for Self-care, Transfers, Locomotion, Bladder/Bowel, and Cognition. The extent to which age, sex, and calendar time was associated with latent class membership, at both admission and discharge, was estimated using ordinal logistic regression, and proportional odds model was calculated for each age and sex. RESULTS: At admission five classes were identified. The two most prevalent classes included people with total or moderate dependency in all FIM subscales except cognition (n = 1205 and n = 1099). The third most common was dependent in ambulation only (n = 523), followed by dependence in ambulation with varying degree of limitation in self-care and transfers (n = 465, and n = 208). At discharge four classes were identified with the largest class comprising of people dependent in ambulation and to a lesser degree in transfers (n = 1010). The second most prevalent class was no dependency (n = 946), followed by two classes with varying dependency in all subscales but cognition (n = 678 and n = 771). CONCLUSION: Overall 62.3% of admissions transitioned to a more functional class by discharge. By discharge 28% of the population was characterized by no dependencies; however, 23% remained with dependencies in all areas. Those in the most dependent classes showed the greatest probability of transitioning to a better class at discharge highlighting the importance of reserving scarce rehabilitation services to those with more disability.

RESUMO

Purpose: To identify older Canadians' perception of the importance of expert-generated elements of walking quality, and the contributors to and consequences of perceived walking quality. Method: Cross-sectional survey of 649 adults was conducted through a commercial participant panel, Hosted in Canada Surveys. Results: Of the 649 respondents, 75% were between 65 and 74 years old (25% ≥ 75) and 49% were women. The most important elements were foot, ankle, hip, and knee mobility with little difference in ranks across walking perception (Fr χ12 = 5.0, p > 0.05). People who were older by a decade were more likely to report poorer walking (POR: 1.4; 95% CI: 1.0, 1.7), as were women compared to men, and people who used a walking aid compared to none. Lung disease showed the highest association with a perception of not walking well (POR: 7.2; 95% CI: 3.7, 14.2). The odds of being willing to pay more for a technology to improve walking were always greater for those with a lower perception of their walking quality. Conclusions: People who perceived their walking quality as poor were more likely to report poorer health and were willing to pay more for a technology to improve walking. This supports the opportunity of leveraging wearable technologies to improve walking.


Objectif : déterminer la perception des Canadiens âgés à l'égard de l'importance des éléments relatifs à la qualité de la marche produits par des experts et établir les incitatifs à la perception de la qualité de la marche, de même que les conséquences s'y rapportant. Méthodologie : sondage transversal auprès de 649 adultes au moyen de Hosted in Canada Surveys, un groupe commercial de participants. Résultats : sur les 649 répondants, 75 % étaient âgés de 65 à 74 ans (25 % ≥ 75 ans), et 49 % étaient des femmes. La mobilité du pied, de la cheville, de la hanche et du genou constituait les éléments les plus importants, et le niveau hiérarchique de chacun différait peu en matière de perceptions de la marche (test de Friedman [Fr] χ2 = 5,0, degré de liberté [ddl] 12, p > 0,05). Les personnes âgées d'une décennie de plus risquaient davantage de déclarer moins bien marcher (rapport de cotes proportionnel [RCP] : 1,4; IC à 95 % : 1,0 à 1,7), tout comme les femmes et les personnes qui utilisaient une aide à la marche. La maladie pulmonaire était la plus liée à la perception de moins bien marcher (RCP : 7,2; IC à 95 % : 3,7, 14,2). La probabilité d'être prêt à payer plus cher pour disposer d'une technologie destinée à améliorer la marche était toujours plus forte chez les personnes qui avaient une moins bonne perception de leur qualité de marche. Conclusion : les personnes qui avaient une moins bonne perception de leur qualité de marche étaient plus susceptibles de se déclarer en moins bonne santé et étaient prêtes à payer plus cher pour disposer d'une technologie destinée à améliorer la marche. Cette constatation confirme la possibilité de mettre à profit des technologies portables pour améliorer la marche.

RESUMO

The health-related quality of life of patients with extremity soft tissue sarcoma (STS) is not precisely captured by current patient-reported outcome measures. Although functional impairment is central to their concerns, multiple sources of distress, emotional restoration, coping strategies, and somatic symptoms are crucial in approaching patients with extremity STS.

RESUMO

BACKGROUND: Functional Neurologic Disorders (FND) are a common but heterogeneous group of disabling conditions. The Emergency Department (ED) is an important venue for care and referral as it is often the first point of contact when patients with FND are faced with a crisis or exacerbation of symptoms. METHODS: ED providers (n = 273) practicing in the Cleveland Clinic Foundation Northeast Ohio network were invited to participate through secure web application electronic surveys. Data were collected on practice profiles, knowledge, attitudes, management of FND, and awareness of available resources for FND. RESULTS: Sixty providers completed the survey (22% response rate; n = 50 ED physicians, 10 advanced care providers) with 95.0% (n = 57) reporting a lack of understanding about FND. The terms Psychogenic Nonepileptic Seizures and stress induced/stress related disease were used by 60.0% (n = 36) and 58.3% (n = 35) respectively. Ninety percent (n = 53) rated their experience with managing FND patients as at least more difficult. Eighty- five percent (n = 51) agreed with "rule out others" and 60% (n = 36) agreed with "caused by psych stress". Eighty six percent (n = 50) believe that there is a difference between FND from malingering. Only one respondent was familiar with any FND resources and 79% (n = 47) reported the need for FND specific educational materials. CONCLUSION: This survey revealed major gaps in knowledge, inaccurate perceptions, and management that differs from the current standard of care among ED providers caring for patients with FND. Educational opportunities are needed to guide diagnosis and evidence-based treatment to optimize management of patients with FND.

RESUMO

BACKGROUND: Challenges to antiretroviral therapy adherence are well-known and continue to be a major hurdle in HIV care. The objective of this paper is to identify barriers to antiretroviral therapy (ART) adherence that are relevant to HIV care from the perspective of people living with HIV and healthcare and social service professionals. METHODS: This study used an online survey design to collect information from the two groups. A total of 100 areas that covered six domains and 20 subdomains were administered to people living with HIV and care professionals in Canada and France. The survey asked participants to rate the importance of each area for HIV care on a four-point Likert scale. Any areas rated 3 or 4 were considered important and ranked. A Chi-square test was conducted for the difference between the groups, people living with HIV and professionals, and between women and men. RESULTS: A response rate of 87% (58/66) in Canada and 65% (38/58) was achieved. 15 of 43 (35%) areas were endorsed as important barriers by both groups, across countries and sex-covering subdomains - drug cost coverage, challenging material circumstances, HIV stigma, and privacy concerns, affect, motivation, beliefs, acceptance of HIV, comorbidity, side effects, and demands and organisation of daily life. People living with HIV identified two, and care professionals identified nine, additional areas as important barriers to HIV care across different domains and subdomains. CONCLUSION: The study identified some common and distinct barriers to ART from the perspective of the people living with HIV and care professionals.

RESUMO

BACKGROUND: The number of wearable technological devices or sensors that are commercially available for gait training is increasing. These devices can fill a gap by extending therapy outside the clinical setting. This was shown to be important during the COVID-19 pandemic when people could not access one-on-one treatment. These devices vary widely in terms of mechanisms of therapeutic effect, as well as targeted gait parameters, availability, and strength of the evidence supporting the claims. OBJECTIVE: This study aimed to create an inventory of devices targeting improvement in gait pattern and walking behavior and identify the strength of the evidence underlying the claims of effectiveness for devices that are commercially available to the public. METHODS: As there is no systematic or reproducible way to identify gait training technologies available to the public, we used a pragmatic, iterative approach using both the gray and published literature. Four approaches were used: simple words, including some suggested by laypersons; devices endorsed by condition-specific organizations or charities; impairment-specific search terms; and systematic reviews. A findable list of technological devices targeting walking was extracted separately by 3 authors. For each device identified, the evidence for efficacy was extracted from material displayed on the websites, and full-text articles were obtained from the scientific databases PubMed, Ovid MEDLINE, Scopus, or Google Scholar. Additional information on the target population, mechanism of feedback, evidence for efficacy or effectiveness, and commercial availability was obtained from the published material or websites. A level of evidence was assigned to each study involving the device using the Oxford Centre for Evidence-Based Medicine classification. We also proposed reporting guidelines for the clinical appraisal of devices targeting movement and mobility. RESULTS: The search strategy for this consumer-centered review yielded 17 biofeedback devices that claim to target gait quality improvement through various sensory feedback mechanisms. Of these 17 devices, 11 (65%) are commercially available, and 6 (35%) are at various stages of research and development. Of the 11 commercially available devices, 4 (36%) had findable evidence for efficacy potential supporting the claims. Most of these devices were targeted to people living with Parkinson disease. The reporting of key information about the devices was inconsistent; in addition, there was no summary of research findings in layperson's language. CONCLUSIONS: The amount of information that is currently available to the general public to help them make an informed choice is insufficient, and, at times, the information presented is misleading. The evidence supporting the effectiveness does not cover all aspects of technology uptake. Commercially available technologies help to provide continuity of therapy outside the clinical setting, but there is a need to demonstrate effectiveness to support claims made by the technologies.

RESUMO

Background: The current measurement approach to frailty is to create an index of frailty status, rather than measure it. The purpose of this study is to test the extent to which a set of items identified within the frailty concept fit a hierarchical linear model (e.g., Rasch model) and form a true measure reflective of the frailty construct. Methods: A sample was assembled from three sources: community organization for at-risk seniors (n=141); colorectal surgery group assessed post-surgery (n=47); and hip fracture assessed post-rehabilitation (n=46). The 234 individuals (age 57 to 97) contributed 348 measurements. The frailty construct was defined according to the named domains within commonly used frailty indices, and items drawn to reflect the frailty came from self-report measures. Performance tests were tested for the extent to which they fit the Rasch model. Results: Of the 68 items, 29 fit the Rasch model: 19 self-report items on physical function and 10 performance tests, including one for cognition; patient reports of pain, fatigue, mood, and health did not fit; nor did body mass index (BMI) nor any item representing participation. Conclusion: Items that are typically identified as reflecting the frailty concept fit the Rasch model. The Frailty Ladder would be an efficient and statistically robust way of combining results of different tests into one outcome measure. It would also be a way of identifying which outcomes to target in a personalized intervention. The rungs of the ladder, the hierarchy, could be used to guide treatment goals.

RESUMO

This study aimed to inform a measurement approach for older persons who wish to engage in active living such as participating in a walking program. The Patient Generated Index, an individualized measurement approach, and directed and summative content analyses were carried out. A sample size of 204 participants (mean age 75 years; 62% women) was recruited; it generated 934 text threads mapped to 460 unique categories within 45 domains with similarities and differences for women and men. The Capability, Opportunity, Motivation, and Behaviors Model best linked the domains. The results suggest that older persons identify the need to overcome impaired capacity, low motivation, and barriers to engagement to live actively. These are all areas that active living programs could address. How to measure the outcomes of these programs remains elusive.

RESUMO

We believe these recommendations constitute "minimum requirements" for health care organizations to move toward greater health equity. As health systems, standards-setting organizations, national and private purchaser organizations, and thought leaders, we represent organizations in the health care ecosystem that can both advise on strategies for adopting the recommendations and have the power and leverage to cause their implementation. We commit individually and collectively to use our leverage to propel their implementation at our own institutions and across the county. We very much hope others will join us.

RESUMO

(1) Background: The aim of this project was to develop a short, HIV-specific, health-related quality of life measure with a scoring system based on patient preferences for the different dimensions of the Preference-Based HIV Index (PB-HIV). (2) Methods: This study is a cross-sectional analysis of data from the Canadian Positive Brain Health Now cohort (n = 854; mean age 53 years). Items from the standardized measures were mapped to the areas from the Patient-Generated Index and formed the domains. A Rasch analysis was used to identify the best performing item to represent each dimension. Each item was then regressed on self-rated health (scored 0 to 100) and the regression parameters were used as scaling weights to form an index score for the prototype measure. (3) Results: Seven independent dimensions with three declarative statements ordered as response options formed the PB-HIV Index (pain, fatigue, memory/concentration, sleep, physical appearance/body image, depression, motivation). Regression parameters from a multivariable model yielded a measure with a scoring range from 0 (worst health) to 100 (perfect health). (4) Conclusions: Preference-based measures are optimal, as the total score reflects gains in some dimensions balanced against losses in others. The PB-HIV Index is the first HIV-specific preference-based measure.

RESUMO

BACKGROUND: Despite declining physical function, individuals with ALS report relative preservation of overall health perception, or health-related quality of life (HRQoL). This paradoxical finding is attributed to psychological adaptation to deficits. OBJECTIVE: The aim of this cross-sectional study was to examine reprioritization of factors that determine HRQoL with disease progression. METHODS: As standard care, patients with ALS self-reported ALSFRS-R (measure of bulbar, motor, and respiratory function), PHQ-9 (measure of depression), and EQ-5D-3L (utility index that includes a visual analog scale asking about health perception [EQ-VAS]). ALS was staged by the FT9 method and classified into early (stages 0-2) and late (stages 3-4) disease. Multigroup structural equation modeling was used to evaluate weights of physical (PHY) and psychological well-being (PSY) for early and late disease, on EQ-VAS (as a measure of overall HRQoL). RESULTS: There were 578 patients (mean age 61.5 ± 11.9, 59% male) with ALS: 423 (73%) early and 155 (27%) late disease. A measurement model was established with good model fit (RMSEA = 0.076, CFI = 0.943, SRMR = 0.045). In adjusted models, standardized weights of PHY and PSY on HRQoL in early disease were 0.34 (standard error = 0.06) and 0.24 (0.06) respectively, whereas for late disease they were 0.39 (0.07) and 0.42 (0.07). Importantly, PHY and PSY were significantly correlated in early but not in late disease. CONCLUSIONS: Our study found health perception is more representative of psychological well-being and less representative of physical function across the disease progression. Greater allocation for psychological health would be the most effective strategy to maximize subjective health status as ALS advances.

RESUMO

Transcranial magnetic stimulation (TMS) is widely used for therapeutic and research purposes such as cognitive studies, treatment of psychiatric disorders, and Parkinson's disease. In research, TMS is perhaps the only technique that can establish a functional connection between brain regions and task performance. In gait research, often TMS is used to identify the extent to which leg motor cortex is involved in different phases on gait cycle. However, using TMS in gait can be challenging for several technical reasons and physiological variations. The objective of this narrative review is to summarize literature in the field of TMS and gait research and present comprehensive challenges. A comprehensive literature search was conducted in PubMed and Google Scholar to identify all relevant literature on TMS and gait. Several critical challenges could potentially impact the findings. For instance, the use of different protocols to obtain motor threshold. This review presents some of the critical challenges in applying TMS during gait. It is important to be aware of these variations and utilize strategies to mitigate some challenges.

RESUMO

BACKGROUND: Over a third of people living with HIV (PLHIV) have suboptimal adherence to antiretroviral therapy (ART). Measures of barriers to ART adherence often lack comprehensiveness. To help manage ART adherence barriers in HIV care, we are developing a new patient-reported outcome measure (PROM) of these barriers (the I-Score). METHODS: We assessed the content validity of 100 items (distinct barriers) to retain only those most relevant to both PLHIV and HIV health/social service providers. A web-based Delphi was conducted in Canada and France, collecting data from December 2018 to October 2019. Items were evaluated on relevance (the combined rated importance and actionability for HIV care of items among both PLHIV and providers); comprehensibility (rated item clarity); comprehensiveness (examined against our conceptual framework); cross-cultural equivalence (based on comparisons by questionnaire language (English, French) and country of residence). Pearson's chi-square tests were used for comparisons by language, country, gender, and stakeholder group (PLHIV, providers). RESULTS: Panelists included 40 PLHIV and 57 providers (66% response rate). Thirty-one items were retained based on consensus thresholds for relevance (minimum: 50% for PLHIV, 60% for providers) and showed good comprehensibility and comprehensiveness, when compared to our conceptual framework (representation of: 6/6 domains, 15/20 subdomains). No significant difference in relevance based on language or country was found among retained items, suggestive of cross-cultural equivalence. Among all 100 items, only 6 significant differences on relevance were observed for gender. For 62 items, the relevance ratings of PLHIV and providers differed significantly, with providers showing greater endorsement of all items but one. DISCUSSION: The Delphi led to a much-needed item reduction. Remaining items highlight the panel's multidimensional priorities for the PROM on ART adherence barriers, with few, if any, differences by language, country, and gender. While the analyses may lack generalizability and power, the sample size is considered adequate for a PROM validation study. CONCLUSION: Retained items showed good content validity. The different patterns of item endorsement observed underscore the utility of engaging multiple stakeholder groups in PROM development for use in clinical practice. The greater endorsement of items by providers versus patients merits further investigation, including the implications of such differentials for measure development.

RESUMO

PURPOSE: Strongly framed research questions are clear as to the population (P), the exposures or interventions (E/I), comparison groups (C), outcomes (O), time when relevant (T), and what the investigator wants to know. A solid framework sets up the measurement model, analysis, and anticipated results. The purpose of this study was to estimate the extent to which research questions in journals that focused on patient-reported outcome measures (PROM) and quality of life (QOL) are clear. METHODS: All 440 research articles published in four PROM journals in 2020. excluding reviews, psychometric, and qualitative papers, were reviewed. Research questions were classified as: (i) adequately framed (ii) poorly framed; or (iii) unframed based on clarity criteria. Examples from each journal were presented and reframed to match results in the article. RESULTS: Of 440 articles, 195 (44.3%) were classified as adequately framed; 230 (52.2%) as poorly framed; and 15 (3.4%) as unframed. There was heterogeneity across journals (Chi-square: 20.8; 6 df; p = 0.002). Only 29% were framed according to what the investigators wanted to know; 72% were framed like a "to do" list; and 6% were framed as a research agenda. CONCLUSION: Almost half of the questions were poorly framed or unframed a practice that could contribute to research wastage. Even "adequately framed" questions rarely stated what they wanted to know a priori, increasing the risk of biased reporting. Researchers, reviewers, and editors should encourage the use established frameworks for research questions.
