Long-term care staffs' experience in facilitating the use of videoconferencing by cognitively impaired long-term care residents during the COVID-19 pandemic: a mixed-methods study.

BACKGROUND: During the COVID-19 pandemic, numerous long-term care (LTC) homes faced restrictions that prevented face-to-face visits. To address this challenge and maintain family connections, many LTC homes facilitated the use of electronic tablets to connect residents with their family caregivers. Our study sought to explore the acceptability of this practice among staff members and managers, focusing on their experiences with facilitating videoconferencing. METHODS: A convergent mixed method research was performed. Qualitative and quantitative data collection through semi-structured interviews to assess the acceptability of videoconferencing in long-term care homes and to explore the characteristics of these settings. Quantitative data on the acceptability of the intervention were collected using a questionnaire developed as part of the project. The study included a convenience sample of 17 staff members and four managers. RESULTS: Managers described LTC homes' characteristics, and the way videoconferencing was implemented within their institutions. Affective attitude, burden, ethicality, opportunity costs, perceived effectiveness, and self-efficacy are reported as per the constructs of the Theoretical Framework of Acceptability. The results suggest a favorable acceptability and a positive attitude of managers and staff members toward the use of videoconferencing in long-term care to preserve and promote contact between residents and their family caregivers. However, participants reported some challenges related to the burden and the costs regarding the invested time and staff shortage. CONCLUSIONS: LTC home staff reported a clear understanding of the acceptability and challenges regarding the facilitation of videoconferencing by residents to preserve their contact with family caregivers.

Validity, sensitivity and specificity of a measure of medication adherence instrument among patients taking oral anticoagulants.

Although self-report instruments are currently considered a valuable tool for measuring adherence, due to their low cost and ease of implementation, there are still important factors that impact measurement accuracy, such as social desirability and memory bias. Thus, the Global Assessment of Medication Adherence Instrument (GEMA) was developed to provide an accurate measure of this construct. The aim of this study was to evaluate the properties of the measurement of the Global Evaluation of Medication Adherence Instrument (GEMA) among patients with chronic diseases. A methodological study was conducted in the public hospital of the state of São Paulo, Brazil. The adherence to anticoagulants as well as the international normalized ratio (INR) was assessed on 127 patients. Besides GEMA, two other instruments were used to assess adherence: the Morisky Medication Adherence Scale-8 (MMAS-8) and the Measurement of Adhesion to Treatments (MAT). The GEMA presented a satisfactory level of specificity (0.76) to identify adherents among those with a stable INR, low sensitivity (0.43) for the identification of non-adherents among those with an unstable INR, and a Positive Predictive Value of 0.70. Positive and weak to moderate correlations were observed between the proportion of doses assessed with GEMA and the scores on the MMAS-8 (r = .26 and r = .22, respectively) and the MAT (r = .22 and r = .30, respectively). The GEMA presented good practicality, acceptability, and evidence of specificity regarding the stability of the INR. The validity of the construct was partially supported by the relationship with self-reported measures of adherence.

Validation d'un questionnaire mesurant la consommation de boissons sucrées, jus et eau auprès d'adolescents francophones.

Purpose: To examine the temporal stability and relative validity of the adapted French version of an English self-reported questionnaire measuring the beverage intake (BEVQ) of adolescents.Methods: The French adaptation of the BEVQ (AF-BEVQ) included conversion from the imperial to the metric system and the adjustment of some formats to those available in Canada. Next, 60 adolescents from two regions in Quebec completed the AF-BEVQ and two web-based 24-hour dietary recalls (R24W) (one for a weekday and one for a weekend day) on two occasions, two weeks apart.Results: The AF-BEVQ had moderate intraclass correlation coefficients (ICC) for amounts of sugar-sweetened beverages (ICC: 0.68; 95% confidence interval [CI]: 0.46-0.81), fruit juice (ICC: 0.54; 95% CI: 0.23-0.72) and water (ICC: 0.66; 95% CI: 0.38-0.81) consumed. The amounts of sugar-sweetened beverages (rs = 0.49; p < 0.0001), fruit juice (rs = 0.38; p = 0.0024) and water (rs = 0.65; p < 0.0001) reported in the AF-BEVQ were significantly correlated with those of both R24Ws.Conclusions: For the most part, the AF-BEVQ had adequate metrological properties. It is an interesting tool to quickly measure the sugar-sweetened beverage, fruit juice and water intake of French-speaking adolescents.

Objectif : Vérifier la stabilité temporelle et validité relative de la version française adaptée d'un questionnaire auto-déclaré en anglais mesurant la consommation de diverses boissons (BEVQ) chez les adolescents.Méthodes : L'adaptation française du BEVQ (AF-BEVQ) comprenait notamment la conversion des unités impériales en unités métriques et l'ajustement de certains formats selon ceux disponibles au Canada. Ensuite, 60 adolescents provenant de deux régions du Québec ont complété l'AF-BEVQ et deux rappels de 24 heures Web (R24W) (un jour de semaine et un de fin de semaine) à deux reprises à deux semaines d'intervalle.Résultats : L'AF-BEVQ avait des coefficients intra-classe (ICC) modérés pour les quantités de boissons sucrées (ICC : 0,68; intervalle de confiance [IC] 95 % : 0,46­0,81), de jus de fruits (ICC : 0,54; IC 95 % : 0,23­0,72) et d'eau (ICC : 0,66; IC 95 % : 0,38­0,81) consommées. Les quantités de boissons sucrées (rs = 0,49; p < 0,0001), de jus de fruits (rs = 0,38; p = 0,0024) et d'eau (rs = 0,65; p < 0,0001) rapportées dans l'AF-BEVQ étaient significativement corrélées à celles des deux R24W.Conclusions : L'AF-BEVQ présentait majoritairement des propriétés métrologiques adéquates. Il est un outil d'intérêt pour mesurer rapidement la consommation de boissons sucrées, de jus de fruits et d'eau d'adolescents francophones.

Acceptability of videoconferencing to preserve the contact between cognitively impaired long-term care residents and their family caregivers: A mixed-methods study.

Visiting restrictions had to be imposed to prevent the spread of the COVID-19 virus and ensure the safety of long-term care home (LTCH) residents. This mixed method study aimed to explore residents' and family caregivers' acceptability of electronic tablets used to preserve and promote contact. Semi-structured individual interviews with 13 LTCH residents and 13 family caregivers were done to study their experiences, as well as the challenges and resources encountered in the implementation and use of videoconferencing. They had to rate, on a scale from 0 to 10, each of the 6 Theoretical Framework of Acceptability' constructs of the acceptability of the intervention. The results confirm acceptability of videoconferencing, giving residents and caregivers the opportunity to talk to and see each other during the pandemic. Videoconferencing had some benefits, such as being less expensive, and taking less time and effort for family caregivers.

Assessing facilitating conditions and barriers for innovation implementation in Canadian long-term care homes: a research protocol.

BACKGROUND: The COVID-19 pandemic has profoundly affected the health and care of older adults, with particularly negative consequences for those residing in long-term care homes (LTCH) and retirement homes (RH). To inform the implementation of interventions with the most potential for impact, Healthcare Excellence Canada identified six promising practices and policy options that can be introduced to ensure that LTCH and RH are better prepared for potential future outbreaks. A total of 22 implementation science teams (ISTs) were funded to support LTCH and RH across Canada in their implementation of these practices. This study aims to identify the enablers and barriers to the successful implementation of evidence-based practices and the impact of intervention in LTCH and RH across Canada. METHODS: A survey-based longitudinal correlational design will be used. The Organizational Readiness for Knowledge Translation (OR4KT) tool will be used to assess the readiness of LTCH and RH to implement the selected practice. The OR4KT includes 59 questions and takes about 15 min to complete. Five to ten respondents per organization, holding different job positions, will be invited by the ISTs to complete the OR4KT in 91 LTCH or RH across Canada at the beginning of the project (T1) and 6 months after the first measurement (T2). DISCUSSION: The study will provide a benchmark for assessing the readiness of LTCH and RH to implement evidence-based practices. It will also inform decision-makers about barriers and facilitators that influence the integration of promising practices in these organizations.

A Mobile Phone App Intervention to Promote Healthy Salt Intake Among Adults: Protocol for a Randomized Controlled Study.

BACKGROUND: There is sound evidence associating high salt intake and a greater risk of cardiovascular and noncardiovascular diseases. High salt intake has been observed in several populations worldwide. Therefore, promoting healthier salt consumption has been encouraged as a low-cost strategy to reduce this risk factor. However, these strategies need to be sound, built on theoretical and methodological bases, and consider the target population's context. OBJECTIVE: This protocol aims to describe a mobile phone app intervention to promote healthy salt intake among adults. METHODS: This is an experimental and longitudinal study protocol conducted in three modules. Module 1 refers to the planning of the intervention based on the Behaviour Change Wheel framework. Module 2 is the development of the mobile phone app intervention based on the date of module 1. In module 3, the intervention will be evaluated using a randomized controlled study, with three steps of data collection in a 2-month follow-up in a sample of 86 adults (43 participants for each group: the control group and intervention group) recruited from the primary health care centers of a Brazilian town. The discretionary salt intake questionnaire will assess salt consumption, the app usability will be assessed using the System Usability Scale, and psychosocial variables (habit, intention, and self-efficacy) will also be measured. RESULTS: Recruitment began in October 2021, and the follow-up will end in August 2022. The results of this study are expected to be published in 2023. CONCLUSIONS: Results from this study will help people to control salt intake when cooking at home, will stimulate self-care, will work as an alternative or supportive method in the relationship between health care professionals and patients, and will contribute to implementing the app intervention to promote healthy salt intake on a large scale.

Content Validity of a Questionnaire Based on the Theory of Planned Behavior to Assess the Psychosocial Determinants of Insulin Adherence.

OBJECTIVES: To verify the content validity of questions of an insulin adherence questionnaire based on the Theory Planned Behavior in outpatients with type 2 diabetes mellitus. METHODS: The instrument was derived from a tool created to evaluate psychosocial determinants of adherence to oral antidiabetics medications in the Brazilian context, and was submitted for evaluation by a committee of experts and members of the target population. The item-level content validity index, the scale-level content validity index averaging calculation method, and the modified kappa coefficient were used to evaluate agreement among specialists. The comprehensibility of the instrument by members of the target population was qualitatively analyzed. RESULTS: The item-level content validity index was found to be lower than desired in 6 of the 20 items analyzed. Of these, one item was modified and 5 were excluded after the comprehensibility evaluation by members of the target population; one item from the perceived control scale was excluded. Content validation resulted in an instrument with 14 items, distributed in the domains intention (4 items), attitude (3 items), perceived norm (4 items), and perceived control (4 items) scales. CONCLUSIONS: The findings support good evidence of the content validity of the instrument for use among people with type 2 diabetes mellitus receiving insulin therapy.

Humanization of care for adult ICU patients: a scoping review protocol.

OBJECTIVE: The objective of this review is to review and map data from studies on the humanization of care in intensive care units based on a conceptual framework. INTRODUCTION: The critical context of adult patients in intensive care units directs the focus on clinical medical interventions, drawing attention away from the humanization of care. Rethinking intensive care is imperative and the humanization of care is an absolute priority. Literature on this topic is scattered under umbrella terms such as "patient-centered care" or specific terms referring to target interventions. A scoping review based on a conceptual framework will map the literature on humanization in intensive care units. INCLUSION CRITERIA: The review will consider studies on the humanization of care, or on one of the seven components of the conceptual framework (communication, visiting hours, patients' and health care professionals' well-being, family involvement and satisfaction, post-intensive care unit syndrome, and physical environment) focusing on adult patients in intensive care units. Studies on co-existing states or end-of-life care will be excluded. METHODS: A search of Embase, PubMed, and CINAHL will be conducted to identify relevant studies in English or French on the humanization of care, holistic care, or person-centered care in an adult intensive-care environment. The time period covered will be January 1, 2010 to the present. An iterative team approach will be used to screen and select studies and extract data. Data will be charted according to study design, distribution in time, cultural context, concepts, use of theoretical models, and intervention. The results will be summarized and reported, identifying the implications for policy, practice, and research.

Impact of a Theory-Based Intervention to Promote Medication Adherence in Patients With a History of Myocardial Infarction.

BACKGROUND: Patient discontinuation of cardioprotective medications after a cardiac ischemic event commonly occurs early after hospital discharge. Theory-based interventions could be effective in promoting better patient self-regulation of health-related behaviors and positive intentions to adhere to the recommended medical regimen. OBJECTIVE: The aim of this study was to evaluate the potential efficacy and feasibility of a theory-based intervention to promote adherence to cardioprotective medications. METHODS: In this mixed-methods quasi-experimental study with 3 time points, we recruited 45 participants with a positive intention to adhere and a history of myocardial infarction. They were recruited in primary care units in Brazil. Data collection occurred in 2 waves (Tb and T60). The intervention consisted of developing action and coping plans, delivered in a 30-minute face-to-face session, with face-to-face reinforcement at a 30-day interval. Quantitative data were submitted to descriptive, Wilcoxon, and McNemar analyses; qualitative data were submitted to content analysis. RESULTS: An increase in the proportion of patients adhering to medications at the end of follow-up was found (T60 - Tb, +60.0%; P < .001). In addition, a significant reduction was found for blood pressure (T60 - Tb, -8.6 mm Hg; P < .001), heart rate (T60 - Tb, -6.6 bpm; P < .001), and low-density lipoprotein (T60 - Tb, -6.2 mg/dL; P < .05). Qualitative results revealed that the intervention was feasible, with an attrition rate of zero. The intervention was found to be easy to apply to patients' daily lives, and there was adequate time for implementation. CONCLUSIONS: Our data confirm the potential efficacy of a theory-based intervention on the promotion of adherence to cardioprotective medications and on the related clinical end points, as well as its feasibility in the clinical context (Universal Trial Number: U1111-1189-9967).

Interventions to Improve Trainers' Learning and Behaviors for Educating Health Care Professionals Using Train-the-Trainer Method: A Systematic Review and Meta-analysis.

INTRODUCTION: Train-the-trainer (TTT) programs are frequently used to facilitate knowledge dissemination. However, little is known about the effectiveness of these programs. Therefore, we sought to assess the impact of TTT programs on learning and behavior of trainers for educating health and social professionals (trainees). METHODS: Guided by the Cochrane Effective Practice and Organisation of Care, we conducted a systematic review. We searched 12 databases until April 2018 and extracted data according to the Population, Intervention, Comparison, Outcome model. Population was defined as trainers delivering training program to health care professionals, and the intervention consists in any organized activity provided by a trainer. There were no restrictive comparators, and outcomes were knowledge, attitude, skill, confidence, commitment, and behavior of trainers. We estimated the pooled effect size and its 95% confidence interval using a random-effect model. We performed a narrative synthesis when meta-analysis was not possible. RESULTS: Of 11,202 potentially eligible references, we identified 16 unique studies. Studies were mostly controlled before-and-after studies and covered a unique training intervention. Targeted trainers were mostly nurses (n = 10) and physicians (n = 5). The most frequent measured outcome was knowledge (n = 12). TTT programs demonstrated significant effect on knowledge (Standardized mean deviation = 0.58; 95% CI = 0.11-1.06; I2 = 90%; P < .01; 10 studies). No studies measured trainers' ability to deliver the training program. DISCUSSION: TTT programs may improve the knowledge of trainers. However, the heterogeneity and small number of studies hamper our ability to draw conclusions that are more robust.

Validity of the Modified Dyspnea Index for the French-Canadian Population.

BACKGROUND AND PURPOSE: Multidimensional tools could evaluate the dyspnea of patients with chronic lung disease. The aim was to validate the use of the French-Canadian version of the modified dyspnea index (MDI) among patients with pulmonary arterial hypertension (PAH) and interstitial lung disease (ILD). METHODS: The Spearman test analyzed the convergent validation of the MDI with pulmonary function tests (PFTs), New York Heart Association (NYHA) functional classification, the Modified Borg Scale, the Veterans Specific Activity Questionnaire (VSAQ), physical capacity, physical activity (Godin-Shephard Leisure-Time Physical Activity Questionnaire [GSLTPAQ]), and quality of life (SF-12). RESULTS: The MDI had a low correlation with PFT and physical activity; a moderate with physical capacity; a high with the physical dimension (SF-12). CONCLUSION: The results support the convergent validation of the MDI French-Canadian version with PAH or ILD.

Stress and cortisol levels among members of the nursing team.

OBJECTIVE: To analyze the characteristics of hospital nursing professionals with the presence of stress, and to associate this with capillary cortisol. METHOD: A cross-sectional, exploratory and correlational study, conducted in a hospital in São Paulo, Brazil. A total of 164 nursing professionals participated; the Perceived Stress Scale was administered, and hair samples were obtained for laboratory analysis. Data were entered into a Microsoft Excel spreadsheet (2010), and then into Microsoft Office and the R software, version 3.2.2. RESULTS: High levels of capillary cortisol in 47% of participants suggest the presence of stress, but no statistical significance between cortisol and stress levels were found. CONCLUSIONS: Stress and capillary cortisol levels were indicative of stress among nursing professionals; however, no association between them was found, although the values found were above those recommended.

Acceptability of a computer-tailored and pedometer-based socio-cognitive intervention in a secondary coronary heart disease prevention program: A qualitative study.

When developing an innovative intervention, its acceptability to patients, health care professionals and managers must be considered to ensure the implementation into practice. This study aims to identify factors influencing the acceptability of a computer-tailored and pedometer-based socio-cognitive intervention for patients with heart disease. Focus group interviews were conducted in two outlying regions of the province of Quebec (Canada). The Theory of Planned Behavior formed the theoretical basis of the interview guide. Two researchers performed verbatim analysis independently until consensus was achieved. The sample included 44 participants divided into six groups (patients n = 7 + 8, health care professionals n = 8 + 8, managers n = 6 + 7). Health care professionals and managers mentioned benefits concerning partners' opportunity to improve assessment and monitoring. Patients believed the intervention could be useful to improve adherence to physical activity. Additional benefits indicated were self-monitoring behavior and improved health-related outcomes. However, patients expressed concern about the online security, fearing possible data breach. Some clinicians felt the pedometer may not be able to evaluate physical activities other than walking. With regard to behavioral control, a web application and pedometer must be easy to use and compatible with services already in place. Further barriers include level of literacy, cost and the various difficulties associated with wearing a pedometer. Findings suggest that, to improve the acceptability of a computer-tailored and pedometer-based socio-cognitive intervention, users must be assured of a secure website, validated, affordable and easy-to-use pedometers, and an intervention adapted to their level of literacy.

Development and Validation of a Salt Food Frequency Questionnaire (FFQ-Na) and a Discretionary Salt Questionnaire (DSQ) for the Evaluation of Salt Intake among French-Canadian Population.

We assessed the reliability and validity of a Salty Food Frequency Questionnaire for Sodium (FFQ-Na) and a Discretionary Salt Questionnaire (DSQ) developed for the French-Canadian population. The reliability was evaluated according to temporal stability over a 7-15 day interval (n = 36). Validity was evaluated by testing the tools against a 24-h urine sodium excretion (24 h Uri-Na) and a 3-day food record, and this at individual and group levels (n = 164). The intra-class coefficients (ICC) values for the test-retest of the DSQ, the FFQ-Na and the two questionnaires combined were 0.73, 0.97 and 0.98 respectively. Correlations of the FFQ-Na with the 24 h Uri-Na and the 3-day food record were 0.3 (p < 0.001) and 0.35 (p < 0.001) respectively. The DSQ showed no significant correlation with the reference measures. The correlation between the two methods combined were 0.29 (p < 0.001) with the 24 h Uri-Na and 0.31 (p < 0.001) with the 3-day food record. The results of Bland-Altman indicated that for the combined questionnaires, there was a bias of measurement (underestimation of intake), but it was constant for every level of intake according to the reference measures. Finally, the cross-classification indicated an acceptable proportion of agreement, but a rate between 20% and 30% of classification in the opposite quartile. In conclusion, the developed tools are reliable and showed some facets of validity.

What methods have been used to estimate salt intake? A systematic review.

The relationship between salt intake and cardiovascular diseases is a contemporary scientific controversy, which has been attributed to the limits of the measures of salt intake used in the studies. Thus, this article sought to systematically review the literature on the methods used to estimate salt intake in different study designs. Of the 124 articles, 60.5% used only biochemical measures, 26.6% only self-report measures and 12.9% reported the combined use of both methods. The 24-hour urinary sodium excretion was the predominant biochemical method (79.1%) and the Food Frequency Questionnaire was the predominant self-report measure (36.4%). Interventional studies used mostly 24-hour urinary sodium excretion; while longitudinal studies used self-report measures. The question guiding the study and its design, as well as constraints related to costs, sample size and feasibility seems to influence the choice of the type of measurement.

Psychosocial determinants of adherence to oral antidiabetic medication among people with type 2 diabetes.

AIMS AND OBJECTIVES: The aim of this study was to identify the psychosocial determinants of adherence to oral antidiabetic medication, according to the Theory of Planned Behaviour (TPB). BACKGROUND: Appropriate adherence to oral antidiabetic medication contributes to long-term glycaemic control. However, glycaemic control is often poor in people with type 2 diabetes, mainly due to the poor adherence to oral antidiabetic agents. DESIGN: Prospective study with 2 waves of data collection, based on STROBE checklist was conducted. One hundred and fifty-seven adults with type 2 diabetes, in chronic use of oral antidiabetic agents, composed the sample. At baseline, self-reported measures of medication adherence (proportion and global evaluation of adherence) and of metabolic control (glycated haemoglobin) of diabetes were obtained. METHODS: The TPB main constructs (attitude, subjective norm and perceived control) and related beliefs were measured. Adherence and metabolic control measurements were obtained in a two-month follow-up (n = 157). RESULTS: Attitude and subjective norm, together, explained 30% of the variability in intention; their underlying belief-based measures (behavioural and normative beliefs) explained 28% of the variability in intention. In addition, intention predicted behaviour at follow-up. However, when added to the prediction model, past behaviour was the only explanatory factor of adherence behaviour. CONCLUSION: Adherence behaviour to oral antidiabetic medication was predicted by intention, which, in turn, was determined by attitude and subjective norm. In order to promote adherence to oral antidiabetic agents, health professionals should include motivational strategies as well as strategies targeted to attitude and subjective norm when designing interventions. RELEVANCE TO CLINICAL PRACTICE: The nonadherence to antidiabetic medication contributes to lack of control of diabetes and ensuing complications. The comprehension of the factors explaining the variability in medication adherence can inform the design of theory-based interventions aimed at promoting this behaviour.

Cross-Cultural Adaptation and Reliability of the French-Canadian Version of the European Heart Failure Self-Care Behaviour Scale-9.

BACKGROUND AND PURPOSE: The purposes of this methodological study were to adapt the European Heart Failure Self-care Behaviour Scale-9 to the French-Canadian population and to evaluate its reliability. METHODS: The adaptation process consisted of translation, back-translation, evaluation by an expert committee, and pretesting. Reliability was evaluated with stability criteria (test-retest) and internal consistency. RESULTS: Pretesting led to testing of two response formats: 5-point Likert scale and the frequency scale. Both demonstrated good levels of agreement between the test-retest, although the values were higher with the frequency format. The Cronbach's alpha coefficients ranged from 0.71 to 0.78 (Likert scale) and 0.70 to 0.83 (frequency scale). CONCLUSION: The French-Canadian version of the EHFScB-9, in both formats, demonstrated good evidence of reliability.
