RESUMO

BACKGROUND: The Biobanque québécoise de la COVID-19 (Quebec Biobank for COVID-19, or BQC19) is a provincial initiative that aims to manage the longitudinal collection, storage, and sharing of biological samples and clinical data related to COVID-19. During the study, BQC19 investigators reported a high loss-to-follow-up rate. The current study aimed to explore motivational and attrition factors from the perspective of BQC19 participants and health care and research professionals. METHODS: This was an inductive exploratory qualitative study. Using a theoretical sampling approach, a sample of BQC19 participants and professionals were invited to participate via semi-structured interviews. Topics included motivations to participate; participants' fears, doubts, and barriers to participation; and professionals' experiences with biobanking during the COVID-19 pandemic. RESULTS: Interviews were conducted with BQC19 participants (n = 23) and professionals (n = 17) from 8 clinical data collection sites. Motivations included the contribution to science and society in crisis, self-worth, and interactions with medical professionals. Reasons for attrition included logistical barriers, negative attitudes about public health measures or genomic studies, fear of clinical settings, and a desire to move on from COVID-19. Motivations and barriers seemed to evolve over time and with COVID-19 trends and surges. Certain situations were associated with attrition, such as when patients experienced indirect verbal consent during hospitalization. Barriers related to human and material resources and containment/prevention measures limited the ability of research teams to recruit and retain participants, especially in the ever-evolving context of crisis. CONCLUSION: The pandemic setting impacted participation and attrition, either by influencing participants' motivations and barriers or by affecting research teams' ability to recruit and retain participants. Longitudinal and/or biobanking studies in a public health crisis setting should consider these factors to limit attrition.

RESUMO

INTRODUCTION: Climate change from greenhouse gas (GHG) emissions represents one of the greatest public health threats of our time. Inhalers (and particularly metred-dose inhalers (MDIs)) used for asthma and chronic obstructive pulmonary disease (COPD), constitute an important source of GHGs. In this analysis, we aimed to estimate the carbon footprint impact of improving three distinct aspects of respiratory care that drive avoidable inhaler use in Canada. METHODS: We used published data to estimate the prevalence of misdiagnosed disease, existing inhaler use patterns, medication class distributions, inhaler type distributions and GHGs associated with inhaler actuations, to quantify annual GHG emissions in Canada: (1) attributable to asthma and COPD misdiagnosis; (2) attributable to overuse of rescue inhalers due to suboptimally controlled symptoms; and (3) avoidable by switching 25% of patients with existing asthma and COPD to an otherwise comparable therapeutic option with a lower GHG footprint. RESULTS: We identified the following avoidable annual GHG emissions: (1) ~49 100 GHG metric tons (MTs) due to misdiagnosed disease; (2) ~143 000 GHG MTs due to suboptimal symptom control; and (3) ~262 100 GHG MTs due to preferential prescription of strategies featuring MDIs over lower-GHG-emitting options (when 25% of patients are switched to lower GHG alternatives). Combined, the GHG emission reductions from bridging these gaps would be the equivalent to taking ~101 100 vehicles off the roads each year. CONCLUSIONS: Our analysis shows that the carbon savings from addressing misdiagnosis and suboptimal disease control are comparable to those achievable by switching one in four patients to lower GHG-emitting therapeutic strategies. Behaviour change strategies required to achieve and sustain delivery of evidence-based real-world care are complex, but the added identified incentive of carbon footprint reduction may in itself prove to be a powerful motivator for change among providers and patients. This additional benefit can be leveraged in future behaviour change interventions.

RESUMO

Responding effectively to external stress is crucial for neurons. Defective stress granule dynamics has been hypothesized as one of the pathways that renders motor neurons in amyotrophic lateral sclerosis (ALS) more prone to early death. Specifically, it is thought that stress granules seed the cytoplasmic TDP-43 inclusions that are observed in the neurons of most ALS patients, as well as ~50% of all frontotemporal dementia (FTD) patients. In this study, we tested this hypothesis in an intact mammalian nervous system. We established an in vivo heat stress paradigm in mice that effectively triggers the eIF2α pathway and the formation of stress granules in the CNS. In non-transgenic mice, we report an age-dependent decline in the formation of heat-induced stress granules, with 18-month-old animals showing a significant impairment. Furthermore, although neuronal stress granules were robustly observed in non-transgenic mice and SOD1G93A mice, they were largely absent in age-matched TDP-43M337V animals. The observed defect in stress granule formation in TDP-43M337V mice correlated with deficits in expression of key protein components typically required for phase separation. Lastly, while TDP-43 was not localized to stress granules, we observed complete nuclear depletion of TDP-43 in a subset of neurons, with the highest proportion being in the TDP-43M337V mice. Overall, our results indicate that mutant TDP-43 expression is associated with defective stress granule assembly and increased TDP-43 nuclear depletion in the mammalian nervous system, which could be relevant to ALS/FTD pathogenesis.

RESUMO

OBJECTIVE: To examine rates of vaccine hesitancy and their correlates among Canadian adults between April 2020 and March 2021. DESIGN: Five sequential cross-sectional age, sex and province-weighted population-based samples who completed online surveys. SETTING: Canada. PARTICIPANTS: A total of 15 019 Canadians aged 18 years and over were recruited through a recognised polling firm (Leger Opinion). Respondents were 51.5% female with a mean age of 48.1 (SD 17.2) years (range 18-95 years) and predominantly white (80.8%). PRIMARY AND SECONDARY OUTCOME MEASURES: Rates of vaccine hesitancy over the five surveys (time points) and their sociodemographic, clinical and psychological correlates. RESULTS: A total of 42.2% of respondents reported some degree of vaccine hesitancy, which was lowest during surveys 1 (April 2020) and 5 (March 2021) and highest during survey 3 (November 2020). Fully adjusted multivariate logistic regression analyses revealed that women, those aged 50 and younger, non-white, those with high school education or less, and those with annual household incomes below the poverty line in Canada were significantly more likely to report vaccine hesitancy, as were essential and healthcare workers, parents of children under the age of 18 and those who do not get regular influenza vaccines. Endorsing prevention behaviours as important for reducing virus transmission and high COVID-19 health concerns were associated with 77% and 54% reduction in vaccine hesitancy, respectively. Having high personal financial concerns was associated with 1.33 times increased odds of vaccine hesitancy. CONCLUSIONS: Results highlight the importance of targeting vaccine efforts to specific groups by emphasising the outsized health benefits compared with risks of vaccination. Future research should monitor changes in vaccine intentions and behaviour to better understand underlying factors.

RESUMO

BACKGROUND: Daily adjuvant endocrine therapy (AET) for 5 or 10 years is the standard of care for women diagnosed with non-metastatic hormone receptor-positive breast cancer. However, many women experience AET-related issues that may hamper quality of life and adherence. Here, we aimed to describe women's perceptions of motivational interviewing (MI)-guided consultations delivered by a trained nurse navigator over the telephone to enhance AET adherence. METHODS: Eighteen women who were first prescribed AET for non-metastatic breast cancer in the last 5 years, who self-reported AET-related issues, and who participated in at least two MI-guided consultations over a year were interviewed about their perceptions of the intervention, using a semi-structured interview guide. Audio recordings were transcribed verbatim and analyzed using a thematic analysis approach. RESULTS: Three main themes emerged from the data about women's perceptions on MI-guided consultations. These consultations were described as (1) a person-centred experience, (2) providing key information about AET, and (3) supportive of present and future AET experience, by contributing to AET side-effect management, motivation, adherence, calming negative emotions, improving well-being and self-esteem, and making women to feel empowered. CONCLUSIONS: Nurse-led telephone-based MI-guided consultations about AET were found to respond to participants' needs and to enhance participants' perceptions of being informed and being supported in experiencing various facets of AET. Telephone-based consultations for AET are perceived as a promising strategy in an increasing virtual care world.

RESUMO

BACKGROUND: Although guidelines long have recommended objective pulmonary function testing to diagnose asthma and COPD, many primary care patients receive a clinical diagnosis of asthma or COPD without objective testing. This often leads to unnecessary treatment with associated incremental costs and side effects and delays actual diagnosis. RESEARCH QUESTION: What are the barriers and enablers to lung function testing for asthma, COPD, or both in primary care? STUDY DESIGN AND METHODS: We searched the literature for qualitative and quantitative studies reporting barriers, enablers, or both to in-office or out-of-office lung function testing for diagnosing asthma, COPD, or both in primary care. Two reviewers independently screened abstracts and full texts, assessed methodologic quality using the Mixed Methods Appraisal Tool, and extracted data from included studies. Identified barriers and enablers were categorized using the Theoretical Domains Framework (TDF), applying a pre-established coding manual. RESULTS: We identified 7,988 unique articles, reviewed 336 full-text articles, and included 18 studies in this systematic review. Of these 18, 12 were quantitative, three were qualitative, and three used mixed methods. All 18 addressed in-office testing and 11 also addressed out-of-office testing. Barriers and enablers overlapped for asthma and COPD, and in-office and out-of-office settings. We identified more reported barriers (eg, lack of knowledge of the usefulness of spirometry) than enablers (eg, skills for performing reliable spirometry). Barriers mapped to nine (of a possible 14) TDF domains (for both in-office and out-of-office settings). Enablers mapped to three domains for in-office testing and five domains for out-of-office testing. INTERPRETATION: Barriers to objective testing for airway disease in primary care are complex and span many theoretical domains. Correspondingly, a successful intervention must leverage multiple behavior change techniques. A theory-based, multifaceted intervention to address underuse of diagnostic testing for asthma or COPD now should be developed and tested.

RESUMO

INTRODUCTION: In mild asthma, as-needed budesonide-formoterol offers similar protection from severe exacerbations as daily inhaled corticosteroids (ICS), with lower ICS exposure but slightly increased symptoms. We sought to develop an electronic decision aid to guide discussions about the pros and cons of these first-line options, while identifying and integrating user preferences. METHODS: Following International Patient Decision Aid Standards, we created a mild asthma decision aid prototype comparing convenience, clinical outcomes, cumulative ICS dose exposure, costs, and side-effects of each option. After face validation, the prototype was iteratively adapted through rapid-cycle development. Each cycle consisted of a patient focus group and a primary care physician interview. We made user preference-based improvements after each round, until reaching a pre-set stopping criterion (no new critical issues identified). We then performed a summative qualitative content analysis. RESULTS: Over 5 cycles, we recruited 21 asthma patients (12/21 women, 10/21 ≥ 60 years old) and 5 physicians. Serial changes included simplification and reduction of text and reading level, inclusion of an ICS "myths" section and elaboration of patient-friendly infographics for numerical comparisons. User preferences fell within Content, Format, and tool use Process themes. In response to decision-making preferences, we created a complementary one-page conversation aid for patient-provider use at the point-of-care. CONCLUSIONS: We present preference-based electronic patient decision and conversation aids for treatment of mild asthma. Our user preference analyses offer useful insights for development of such tools in other chronic diseases. These tools now require integration into point-of-care workflows for measurement of real-world uptake and impact.

RESUMO

AIM: We compared educational outcomes associated with an active vs. passive continuing professional development activity on self-management support for respiratory educators. BACKGROUND: There is a need to identify learning activities associated with the most successful continuing professional development programs for respiratory educators. DESIGN: This was a non-randomized controlled mixed-methods study recruiting respiratory educators attending a continuing professional development activity on self-management support. METHODS: In the experimental group, active learning methods (role-play simulations) were employed, whereas passive learning methods (lecture) were used in the comparison group. Educators were allocated to the comparison group (first 15 months of the study), then to the experimental group (last 17 months). Educators filled questionnaires measuring pre-/post-activity knowledge about self-management support (score 0-25) and self-reported competence (score 1-10). Scores were compared using mixed-effect models. Interviews with educators were conducted and content analysis was performed. RESULTS: We recruited 94/94 educators (active: n = 51; passive: n = 43). Knowledge scores increased to a greater extent in the active vs. passive learning group (adjusted difference-in-difference [aDID]=2.01; 95% confidence interval [95%CI]: 0.14-3.88), although competence scores increased to a greater extent in the passive learning group (aDID=-0.38; 95%CI: -1.56 to -0.04). Reflecting on their competence, educators of the active learning group identified the need to further improve their self-management support skills, whereas educators of the passive learning group did not. CONCLUSIONS: Our results show that an active learning continuing professional development activity on self-management support could help educators to better apply knowledge and appears to engage them in a process of reflection on action.

RESUMO

RNA binding proteins (RBPs) play a key role in cellular growth, homoeostasis and survival and are tightly regulated. A deep understanding of their spatiotemporal regulation is needed to understand their contribution to physiology and pathology. Here, we have characterized the spatiotemporal expression pattern of hnRNP A1 and its splice variant hnRNP A1B in mice. We have found that hnRNP A1B expression is more restricted to the CNS compared to hnRNP A1, and that it can form an SDS-resistant dimer in the CNS. Also, hnRNP A1B expression becomes progressively restricted to motor neurons in the ventral horn of the spinal cord, compared to hnRNP A1 which is more broadly expressed. We also demonstrate that hnRNP A1B is present in neuronal processes, while hnRNP A1 is absent. This finding supports a hypothesis that hnRNP A1B may have a cytosolic function in neurons that is not shared with hnRNP A1. Our results demonstrate that both isoforms are differentially expressed across tissues and have distinct localization profiles, suggesting that the two isoforms may have specific subcellular functions that can uniquely contribute to disease progression.

RESUMO

The success of large-scale COVID-19 vaccination campaigns is contingent upon people being willing to receive the vaccine. Our study explored COVID-19 vaccine hesitancy and its correlates in eight different countries around the globe. We analyzed convenience sample data collected between March 2020 and January 2021 as part of the iCARE cross-sectional study. Univariate and multivariate statistical analyses were conducted to explore the correlates of vaccine hesitancy. We included 32,028 participants from eight countries, and observed that 27% of the participants exhibited vaccine hesitancy, with increases over time. France reported the highest level of hesitancy (47.3%) and Brazil reported the lowest (9.6%). Women, younger individuals (≤29 years), people living in rural areas, and those with a lower perceived income were more likely to be hesitant. People who previously received an influenza vaccine were 70% less likely to report COVID-19 vaccine hesitancy. We observed that people reporting greater COVID-19 health concerns were less likely to be hesitant, whereas people with higher personal financial concerns were more likely to be hesitant. Our findings indicate that there is substantial vaccine hesitancy in several countries, with cross-national differences in the magnitude and direction of the trend. Vaccination communication initiatives should target hesitant individuals (women, younger adults, people with lower incomes and those living in rural areas), and should highlight the immediate health, social and economic benefits of vaccination across these settings. Country-level analyses are warranted to understand the complex psychological, socio-environmental, and cultural factors associated with vaccine hesitancy.

RESUMO

Background: There is a need to develop specific care route for vulnerable people with hepatitis C virus. Objective: At a nurse-led clinic, we aimed to: (1) report the prevalence of patients initiating an hepatitis C treatment who (a) achieved sustained virologic response and (b) were adherent to their treatment; and (2) explore factors associated with adherence and sustained virologic response. Design: A clinical record-based prospective cohort study. Setting: A community-based nurse-led clinic coordinating outreach services for people with hepatitis C virus in Québec City, Québec, Canada. Population: All patients initiating an hepatitis C treatment at the nurse-led clinic from January 1, 2012 to December 31, 2017 (end of data collection). Methods: Patients were followed from the day they initiated their hepatitis C treatment, up to 24 weeks after the end of the treatment. Sustained virologic response was achieved if hepatitis C virus ribonucleic acid (RNA) was undetectable or below the lower limit of quantification at week 12 or later. Patients who reported hepatitis C treatment completion without missing any doses were considered adherent. Factors associated with adherence and sustained virologic response were identified using adjusted prevalence ratios. Results: A total of 171 patients infected with hepatitis C virus (women: n = 51, 30%; criminal record: n = 102, 60%; substance addiction: n = 99, 58%) initiated an hepatitis C treatment at the nurse-led clinic. Overall, 126/171 (74%) patients were adherent. Patients using illicit drugs were less likely to be adherent (adjusted prevalence ratio 0.77, 95% confidence interval 0.67-0.89). Among 156/171 (91%) patients with an hepatitis C virus RNA test post-treatment, 96% (n = 149) achieved sustained virologic response. Patients who were less likely to achieve sustained virologic response were those who were non-adherent (adjusted prevalence ratio 0.81, 95% confidence interval 0.68-0.98) or who had a criminal record (adjusted prevalence ratio 0.87, 95% confidence interval 0.79-0.97). Conclusions: A nurse-led clinic could fill an important gap in hepatitis C health services targeted at vulnerable people in a community setting, to drive adherence and achievement of sustained virologic response.

RESUMO

OBJECTIVES: We sought to describe training activities on self-management support (SMS) for asthma educators and the effects of SMS provided by trained educators on asthma patient outcomes. METHODS: We conducted a systematic review of six medical databases and sought for trials assessing SMS provided for adults with asthma by trained educators. Two reviewers independently selected and extracted data on asthma educators' training activities and patient outcomes. We performed meta-analyses for asthma-related quality of life (QoL) and asthma control. RESULTS: We screened 3217 records and included 16 trials. Learning activities and assessments were reported in 8/16 and 4/16 trials, respectively. Compared to usual care, trained asthma educators provided SMS that resulted in clinically important improvements in QoL (pooled mean difference [MD] = 0.52; 95% confidence interval [95%CI]: 0.19 to 0.83) and asthma control (pooled MD= -0.68; 95%CI: -0.99 to -0.38). CONCLUSION: Although asthma-specific SMS provided by trained educators had a beneficial effect over the current care, our results highlight the need to better describe training activities for asthma educators. PRACTICE IMPLICATIONS: This systematic review provides key elements of efficient training activities for asthma educators and reaffirms the importance of training educators to provide SMS in order to improve asthma patients' QoL and asthma control.

RESUMO

Amyotrophic lateral sclerosis (ALS) is a fatal disease, characterized by the selective loss of motor neurons leading to paralysis. Mutations in the gene encoding superoxide dismutase 1 (SOD1) are the second most common cause of familial ALS, and considerable evidence suggests that these mutations result in an increase in toxicity due to protein misfolding. We previously demonstrated in the SOD1G93A rat model that misfolded SOD1 exists as distinct conformers and forms deposits on mitochondrial subpopulations. Here, using SOD1G93A rats and conformation-restricted antibodies specific for misfolded SOD1 (B8H10 and AMF7-63), we identified the interactomes of the mitochondrial pools of misfolded SOD1. This strategy identified binding proteins that uniquely interacted with either AMF7-63 or B8H10-reactive SOD1 conformers as well as a high proportion of interactors common to both conformers. Of this latter set, we identified the E3 ubiquitin ligase TNF receptor-associated factor 6 (TRAF6) as a SOD1 interactor, and we determined that exposure of the SOD1 functional loops facilitates this interaction. Of note, this conformational change was not universally fulfilled by all SOD1 variants and differentiated TRAF6 interacting from TRAF6 noninteracting SOD1 variants. Functionally, TRAF6 stimulated polyubiquitination and aggregation of the interacting SOD1 variants. TRAF6 E3 ubiquitin ligase activity was required for the former but was dispensable for the latter, indicating that TRAF6-mediated polyubiquitination and aggregation of the SOD1 variants are independent events. We propose that the interaction between misfolded SOD1 and TRAF6 may be relevant to the etiology of ALS.

RESUMO

Background: Spirometry is the best test to demonstrate airway obstruction, but remains underused in primary care. Objectives: We assessed, among family medicine physician teachers and residents, their intention to prescribe spirometry in patients suspected of chronic obstructive pulmonary disease and their intention to interpret the results. This evaluation is based on the theoretical framework proposed by Godin et al. for the study of factors influencing healthcare professionals' behavior. Methods: Participants of this descriptive cross-sectional study were recruited from eight Family medicine units (FMUs) of Laval University's network. They completed a 23-item self-administered questionnaire measuring their intention to prescribe and to interpret spirometry as well as some determinants of this intention (beliefs about capabilities, beliefs about consequences, social influence and moral norm). Answers to each of the items were scored on a Likert scale (score 1 to 7) where a higher score indicated a greater agreement with the statement. Results: Of the 284 eligible physicians, 104 were included. The mean score ± standard deviation of physicians' intention to prescribe spirometry (6.6 ± 0.7) was higher than to interpret the results (5.8 ± 1.5). Mean scores for all determinants of intention measured were also higher for prescription than for interpretation of spirometry. Conclusion: The results suggest that participants have a very strong intention to prescribe spirometry. Although the intention to interpret the results is positive, it is weaker than for the prescription of the test. Further studies will be needed to assess the barriers to spirometry interpretation.

RESUMO

BACKGROUND: There is a necessity to better document the effect of continuing education activities targeted at respiratory educators providing self-management support for patients with chronic obstructive pulmonary disease (COPD). We therefore sought to describe real-life COPD-specific self-management support delivered by respiratory educators who participated in a lecture-based continuing education activity and assess the outcomes of patients with COPD. METHODS: We conducted a convergent embedded mixed-methods study. Respiratory educators attended a 7-h, lecture-based continuing education activity on self-management support held in Québec, Canada. Four months after the continuing education activity, in their professional practice, trained educators provided self-management support to patients with COPD. One month later, to describe the components of self-management support provided, individual telephone interviews were conducted with educators. Interviews were transcribed verbatim and were qualitatively analyzed. Before self-management support and 6 months afterwards, we assessed the following clinical outcomes of patients with COPD: (1) quality of life (St. George's Respiratory Questionnaire for COPD patients, Impact domain; score 0-100; minimal clinically important difference = - 4; telephone administered); (2a) whether patients had one or more unscheduled doctor visit, (2b) one or more emergency room visit, and (2c) one or more hospitalization in the 6 preceding months (Survey on Living with Chronic Diseases in Canada; telephone administered); and (3a) health-directed behaviors and (3b) skill and technique acquisition (Health Education Impact Questionnaire; score 1-4; self-administered at home). We used mixed models to estimate mean differences and prevalence ratios, with associated 95% confidence intervals. RESULTS: Trained respiratory educators (nurse: n = 1; respiratory therapist: n = 3; ≥ 15 years of experience of care with patients with chronic disease) invited 75 patients with COPD to participate in the study. Fifty-four individuals with COPD (age, mean ± standard deviation: 68 ± 8 years; men: n = 31) were enrolled and received self-management support. Qualitative analyses revealed that self-management support consisted of one to two visits that included: (1) provision of information on COPD; (2) training in inhalation technique; and (3) smoking cessation advice. No educator reported implementing two or more follow-up visits because of a lack of time and human resources in their work setting. Among patients with COPD, improvements in quality of life were clinically important (adjusted mean difference = - 12.75; 95% confidence interval - 18.79 to - 6.71; p = 0.0001). Health-resource utilization was not different over time (all p values > 0.05). Improvements in health-directed behaviors and skill and technique acquisition were statistically significant (health-directed behaviors: adjusted mean difference = 0.50; 95% confidence interval 0.23-0.77; p = 0.0005; skill and technique acquisition: adjusted mean difference = 0.12; 95% confidence interval 0.01-0.23; p = 0.0293). CONCLUSIONS: Following a 7-h, lecture-based continuing education activity on COPD-specific self-management support, respiratory educators with significant experience of care provided self-management support that included provision of information, inhalation technique training, and smoking cessation advice. This resulted in enhanced patient quality of life, health-directed behaviors, and skill and technique acquisition. To decrease health resource utilization, the training could employ active learning methods. More time and resources could also be devoted to implementing regular follow-up visits.

RESUMO

Objective: Individuals who are adherent to their asthma inhaled maintenance medication: (1) initiate their treatment (take the first dose); (2) implement it (take it as per prescribed dosing regimen); and persist with it (take it for the entire prescribing period). To avoid unnecessary hospitalizations and costs, patient adherence should be routinely assessed. To this end, we aimed to identify patient-reported outcome instruments (PROs) used for measurement of patient adherence to inhaled maintenance medication in asthmatic adults and to report on the adherence stage that these instruments measured. Data sources: We conducted a scoping review of six databases. Study selection: We searched for studies in which PROs were used to measure patient adherence to inhaled maintenance medication in asthmatic participants aged ≥18 years. We extracted and synthesized data in order to list the available PROs and to report the adherence stages that these instruments measured. Results: We included 186 studies (87 PROs). Among all 87 instruments, none were found to measure all three adherence stages. We found that 1 measured initiation, 2 evaluated initiation and implementation, 74 assessed implementation, 7 measured implementation and persistence. The most used instrument (n = 41 studies or 22%) was the Self-Reported Medication-Taking Scale, which was found to assess implementation only. Conclusion: Our results suggest that no single PRO exists to measure initiation, implementation and persistence with asthma inhaled maintenance medication. Results from this review could therefore guide the development or refinement of PROs that would aim to measure all three adherence stages.

RESUMO

OBJECTIVE: To assess whether adding a video on atrial fibrillation (AF) to a face-to-face educational session improves quality of life (QoL), knowledge, and health resource utilization (HRU) among AF patients. METHODS: In this parallel clinical trial, adults with AF received a face-to-face educational session on AF and were randomly allocated to watch an educational video or not. Self-reported questionnaires measured QoL (primary outcome; score 0-100), AF knowledge (score 0-25), and HRU. Data were collected before and after interventions. Within- and between-group changes were estimated by mixed models. RESULTS: Sixty participants (age: 56 ± 13 years; men: n = 41) were allocated to watch the video after education (n = 30) or to receive education only (n = 30). Within groups over time, QoL and knowledge significantly improved. Knowledge increased by 2.3 units (95% confidence interval: 0.5-4.1) more in participants who watched the video than in others (P = 0.014). Changes in QoL and HRU were not different between groups. CONCLUSION: Complementing education with a video on AF did not result in additional positive impacts on QoL and HRU among AF adults but led to greater improvements in AF knowledge. PRACTICE IMPLICATIONS: The video on AF could be used as part of educational sessions to increase AF knowledge in AF patients.

RESUMO

BACKGROUND: Therapeutic patient education (TPE) improves quality of life and reduces health care utilization among patients with chronic obstructive pulmonary disease (COPD). However, benefits from TPE might depend on the performance of the educators and training is needed to ensure the effective delivery of TPE interventions. Based on the framework by Moore et al. (J Contin Educ Health Prof 29:1-15, 2009), we will compare the impact of two continuing education (CE) activities on TPE in regard to the following educational outcomes: (1) learning, (2) self-report of competence, (3) performance of the educators, and (4) outcomes of COPD patients who will meet the newly trained educators for TPE. METHODS: We will conduct a non-randomized controlled study using mixed methods. Educators will first participate in a CE activity on TPE that will include a role-playing simulation (experimental group) or in a lecture on TPE (comparison group) and then will perform TPE in COPD patients. Among educators, we will assess: (1) learning, by measuring knowledge about TPE, and (2) self-report of competence using self-administered questionnaires before and after the activity. Then, after the CE activity, we will assess (3) educators' performance levels in delivering TPE by rating a videotaped TPE intervention. In COPD patients who will meet the newly trained educators for TPE after either CE activity, we will assess (4) quality of life and resource utilization using interviewer-administered questionnaires, before and after TPE. Statistical analyses will compare the experimental group against the comparison group using multivariate models. Using a semi-structured interview guide, we will conduct interviews with educators and perform content analysis. Results will be integrated in order that qualitative results further explain the quantitative ones. DISCUSSION: To the best of our knowledge, this is the first controlled mixed methods study to compare the impact of two CE activities on TPE in regard to four educational outcomes. We believe this study will serve as a model for evaluating CE activities on TPE. Results from this study could increase educators' performance levels in delivering effective TPE interventions, and, in turn, COPD patient outcomes. TRIAL REGISTRATION: The study was registered on https://clinicaltrials.gov/ ( NCT02870998 ) on March 15, 2016.

RESUMO

AIM: The aim of the present study was to identify systematically the measurement properties of patient-reported outcome instruments (PROs) that evaluate adherence to inhaled maintenance medication in adults with asthma. METHODS: We conducted a systematic review of six databases. Two reviewers independently included studies on the measurement properties of PROs that evaluated adherence in asthmatic participants aged ≥18 years. Based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN), the reviewers: (i) extracted data on internal consistency, reliability, measurement error, content validity, structural validity, hypotheses testing, cross-cultural validity, criterion validity and responsiveness; (ii) assessed the methodological quality of the included studies; (iii) assessed the quality of the measurement properties (positive or negative); and (iv) summarized the level of evidence (limited, moderate or strong). RESULTS: We screened 6068 records and included 15 studies (14 PROs). No studies evaluated measurement error or responsiveness. Based on methodological and measurement property quality assessments, we found limited positive evidence of: (i) internal consistency of the Adherence Questionnaire, Refined Medication Adherence Reason (MAR) scale, Medication Adherence Report Scale for Asthma (MARS-A) and Test of the Adherence to Inhalers (TAI); (ii) reliability of the TAI; and (iii) structural validity of the adherence questionnaire, MAR scale, MARS-A and TAI. We also found limited negative evidence of: (i) hypotheses testing of the Adherence Questionnaire; (ii) reliability of the MARS-A; and (iii) criterion validity of the MARS-A and TAI. CONCLUSIONS: Our results highlighted the need to conduct further high-quality studies to evaluate the reliability, validity and responsiveness of the available PROs.

RESUMO

OBJECTIVE: Based on the Knowledge-to-Action Cycle, we assessed the self-reported implementation and perception of asthma clinical practice guideline (CPG) recommendations in primary care physicians (PCPs), along with the barriers and facilitators to CPG use in primary care. METHODS: We conducted a cross-sectional study. Using the extended Asthma Physicians' Practice Assessment Questionnaire©, PCPs self-reported the following: their knowledge of 15 key asthma CPG recommendations, the perceived usefulness of each of these recommendations, their motivation to apply these recommendations, and their agreement with the content of these recommendations. Participants also reported the barriers and facilitators to CPG use in primary care. RESULTS: Out of the 46 potential participants, 43 physicians completed the questionnaire (response rate: 93%). Results underlined care gaps regarding the provision of asthma education and written action plans, inhaler technique demonstrations, and assessment of patients' concerns. Results showed that the majority of physicians knew the key asthma CPG recommendations, but their motivation to implement them and the perceived usefulness of these recommendations varied from one proposal to another. Main barriers to the implementation of these recommendations were related to time and resources. PCPs stressed the importance of teamwork for enhancing the use of asthma CPGs in primary care. CONCLUSIONS: Our results suggest that the implementation of asthma CPGs remains suboptimal in primary care. Interventions addressing the identified barriers and providing facilitators to asthma CPG implementation, such as continuing education, could be implemented and evaluated to sustain asthma CPG use in primary care settings.
