WEB OF TRANSFORMATIONS: impact of multicomponent intervention on the relationship between sociodemographic indicators, changes in body composition, cardiorespiratory fitness and biochemical markers in adolescents with overweight and obesity

The study aims to analyze the relationships between changes after multicomponent intervention in sociodemographic indicators, body composition, cardiorespiratory fitness and biochemical markers in overweight/obese adolescents. Quasi-experimental study with 33 overweight/obese adolescents (17 in the intervention group (IG) and 16 in the control group (16)), in which the GI participated in the multicomponent intervention for 24 weeks. Sociodemographic indicators, body composition, cardiorespiratory fitness and biochemical markers were evaluated. Network analysis was performed using JASP software. In GI, the reduction in %BF proved to be the variable with greater connectivity and strength in the network compared to the control network. Changes in %BF were related to changes in ACR, BMI and leptin. It is concluded that the reduction in %BF is the most important variable in network relationships after the intervention, suggesting that the greater the reduction in %BF, the greater the effect on variables such as BMI, ACR and leptina.

Cost-Effectiveness of a Multicomponent Primary Care Intervention for Hypertension

BACKGROUND

The SingHypertension primary care clinic intervention, which consisted of clinician training in hypertension management, subsidized single-pill combination medications, nurse-delivered motivational conversations and telephone follow-ups, improved blood pressure control and cardiovascular disease (CVD) risk scores relative to usual care among patients with uncontrolled hypertension in Singapore. This study quantified the incremental cost-effectiveness, in terms of incremental cost per unit reduction disability-adjusted life years, of SingHypertension relative to usual care for patients with hypertension from the health system perspective.

METHODS AND RESULTS

We developed a Markov model to simulate CVD events and associated outcomes for a hypothetical cohort of patients over a 10-year period. Costs were measured in US dollars, and effectiveness was measured in disability-adjusted life years averted. We present base-case results and conducted deterministic and probabilistic sensitivity analyses. Based on a willingness-to-pay threshold of US $55 500 per DALY averted, SingHypertension was cost-effective for patients with hypertension (incremental cost-effectiveness ratio: US $24 765 per disability-adjusted life year averted) relative to usual care. This result held even if risk reduction was assumed to decline linearly to 0 over 10 years but not sooner than 7 years. Incremental cost-effectiveness ratios were most sensitive to the magnitude of the reduction in CVD risk; at least a 0.13% to 0.16% point reduction in 10-year CVD risk is required for cost-effectiveness. Probabilistic sensitivity analysis indicates that SingHypertension has a 78% chance of being cost-effective at the willingness-to-pay threshold.

CONCLUSIONS

SingHypertension represents good value for the money for reducing CVD incidence, morbidity, and mortality and should be considered for wide-scale implementation in Singapore and possibly other countries.

Implementation of the ASCENT Trial to Improve Transplant Waitlisting Access

Introduction

The Allocation System for changes in Equity in Kidney Transplantation (ASCENT) study was a hybrid type 1 trial of a multicomponent intervention among 655 US dialysis facilities with low kidney transplant waitlisting to educate staff and patients about kidney allocation system (KAS) changes and increase access to and reduce racial disparities in waitlisting. Intervention components included a staff webinar, patient and staff educational videos, and facility-specific feedback reports.

Methods

Implementation outcomes were assessed using the Reach, Effectiveness, Adoption, Implementation, and Maintenance Framework. Postimplementation surveys were administered among intervention group facilities (n = 334); interviews were conducted with facility staff (n = 6). High implementation was defined as using 3 to 4 intervention components, low implementation as using 1 to 2 components, and nonimplementation as using no components.

Results

A total of 331 (99%) facilities completed the survey; 57% were high implementers, 31% were low implementers, and 12% were nonimplementers. Waitlisting events were higher or similar among high versus low implementer facilities for incident and prevalent populations; for Black incident patients, the mean proportion waitlisted in low implementer facilities was 0.80% (95% confidence interval [CI]: 0.73-0.87) at baseline and 0.55% at 1-year (95% CI: 0.48-0.62) versus 0.83% (95% CI: 0.78-0.88) at baseline and 1.40% at 1-year (95% CI: 1.35-1.45) in high implementer facilities. Interviews revealed that the intervention helped facilities prioritize transplant education, but that intervention components were not uniformly shared.

Conclusion

The findings provide important context to interpret ASCENT effectiveness results and identified key barriers and facilitators to consider for future modification and scale-up of multilevel, multicomponent interventions in dialysis settings.

Effect of a Multicomponent Intervention with Tele-Rehabilitation and the Vivifrail© Exercise Programme on Functional Capacity after Hip Fracture: Study Protocol for the ActiveFLS Randomized Controlled Trial

INTRODUCTION

Hip fractures are the most common fracture leading to hospitalization and are associated with high costs, mortality rates and functional decline. Although several guidelines exist for preventing new fractures and promoting functional recovery, they tend to focus on osteoporosis treatment and do not take into account the complexity of frailty in older adults and geriatric syndromes, which are important factors in individuals at risk of suffering from frailty fractures. Moreover, most health systems are fragmented and are incapable of providing appropriate management for frail and vulnerable individuals who are at risk of experiencing fragility fractures. Multicomponent interventions and physical exercise using tele-rehabilitation could play a role in the management of hip fracture recovery. However, the effectiveness of exercise prescription and its combination with a comprehensive geriatric assessment (CGA) is still unclear.

METHODS

This randomized clinical trial will be conducted at the Hospital Universitario de Navarra (Pamplona, Spain). A total of 174 older adults who have suffered a hip fracture and fulfil the criteria for inclusion will be randomly allocated to either the intervention group or the control group. The intervention group will receive a multicomponent intervention consisting of individualized home-based exercise using the @ctive hip app for three months, followed by nine months of exercise using Vivifrail. Additionally, the intervention group will receive nutrition intervention, osteoporosis treatment, polypharmacy adjustment and evaluation of patient mood, cognitive impairment and fear of falling. The control group will receive standard outpatient care according to local guidelines. This research aims to evaluate the impact of the intervention on primary outcome measures, which include changes in functional status during the study period based on the Short Physical Performance Battery.

DISCUSSION

The findings of this study will offer valuable insights into the efficacy of a comprehensive approach that considers the complexity of frailty in older adults and geriatric syndromes, which are important factors in individuals at risk of suffering from frailty fractures. This study's findings will contribute to the creation of more effective strategies tailored to the requirements of these at-risk groups.

Cost-utility of a multicomponent intervention for fibromyalgia versus usual care: a pragmatic randomised controlled trial

OBJECTIVE

To perform an economic evaluation on a multicomponent intervention programme for patients with fibromyalgia syndrome compared with usual clinical practice in primary care.

DESIGN

A cost-utility analysis was conducted alongside a pragmatic randomised controlled trial (ClinicalTrials.gov: https://clinicaltrials.gov/ct2/show/record/NCT04049006) from a societal perspective, a human capital approach, and a 1-year time horizon.

PATIENTS

Patients diagnosed with fibromyalgia  syndrome from the public health system in south Catalonia, Spain.

METHODS

Crude and adjusted incremental cost- utility ratios were estimated to compare the treatment strategies based on cost estimations (direct medical costs and productivity losses) and quality-adjusted life years. One-way and 2-way deterministic sensitivity analyses were performed.

RESULTS

The final analysed sample comprised 297 individuals, 161 in the intervention group and 136 in the control group. A crude incremental cost-utility ratio of € 1,780.75 and an adjusted ratio of € 851.67 were obtained, indicating that the programme  significantly improved patients' quality of life with a cost-increasing outcome that fell below the cost-effectiveness threshold. The sensitivity analysis  confirmed these findings when  varying large cost components, and showed dominance when increasing session attendance.

CONCLUSION

The proposed multicomponent intervention programme was cost-effective compared with usual care for fibromyalgia, which supports its addition to standard practice in the regional  primary care service.

Effects of a multicomponent intervention on cardiovascular risk factors in overweight children: a randomized clinical trial in light of complex systems

Analyzing the effects of interventions from a theoretical and statistical perspective that allows understanding these dynamic relationships of obesity etiology can be a more efficient and innovative way of understanding the phenomenon's complexity. Thus, we aimed to analyze the pattern of cardiovascular risk factors between-participants, and the effects within-participants of a multidisciplinary intervention on cardiovascular risk factors in overweight children. This is a randomized clinical trial, and 41 participated in this study. A multicomponent intervention (physical activities, nutritional and psychological counseling) was performed for 10 weeks. Anthropometric and hemodynamics measurements, lipid and glucose profile, cardiorespiratory fitness, and left ventricular mass were evaluated. A network analysis was done. Considering patterns in the network at baseline, WC, WHR, BMI, and Fat were the main variables for cardiovascular risks. Group was the most critical variable in the within-participant network. Participating in a multicomponent intervention and decreasing body fat promoted beneficial cardiovascular factors.

The PRO-HOME Project. A multicomponent intervention for the protected discharge from the hospital of multimorbid and polytreated older individuals by using innovative technologies: A pilot study

BACKGROUD

Discharge planning from the hospital of frail older patients is an important step to avoid inappropriate long-stay hospitalizations and to prevent the risks related to the prolonged hospitalization. In this frame, we developed an experimental trial-'PRO-HOME', a multicomponent programme of interventions for multimorbid and polytreated hospitalized older patients.

AIM

The main aim of the study was to develop a protected discharge facility using a mini apartment equipped with advanced architectural and technological components to reduce the length of hospital stay of older participants (aged 65+ years old) admitted to the hospital for an acute event, deemed stable and dischargeable.

MATERIALS AND METHODS

This is a pilot randomized controlled study, comparing 30 hospitalized participants included in a multidimensional, transitional care programme based on information and communication technologies to 30 patients in standard usual care until hospital discharge.

RESULTS

We presented the study design of the PRO-HOME programme, including architectural and technological components, the enrolment procedures, the components of the intervention that is physical activity, cognitive training and life-style education and the evaluation method of the intervention based on the Comprehensive Geriatric Assessment to explore the changes in the individual domains that are target of the multicomponent intervention.

CONCLUSIONS

The final results will suggest whether the PRO-HOME programme represents a useful and feasible intervention to reduce the length of hospital stay of multimorbid and polytreated hospitalized older patients and improve their physical and cognitive performances and overall quality of life.

PATIENT OR PUBLIC CONTRIBUTION

Due to the characteristics of the population of interest of the PRO-HOME study, we involved in the study design and programme of the activities the participants enrolled in a previous smart home-based project named MoDiPro carried-out during a 3-year period. The elderly participants from the local population involved were asked, by means of focus groups, for feedback on their experience in MoDiPro, and their suggestions were integrated into the design phase of the current PRO-HOME project. The focus groups included open group interviews with a qualitative collection of the patients' feedback so that the participants could interact with each other.

Effectiveness and health benefits of a nutritional, chronobiological and physical exercise primary care intervention in fibromyalgia and chronic fatigue syndrome: SYNCHRONIZE + mixed-methods study protocol

INTRODUCTION

Chronic pain, fatigue and insomnia are classic symptoms of fibromyalgia (FM) and chronic fatigue syndrome (CFS) and seriously affect quality of life. Nutrition and chronobiology are often overlooked in multicomponent approach despite their potential. This study aims to evaluate the effectiveness of a multidisciplinary group intervention based on nutrition, chronobiology, and physical exercise in the improvement of lifestyle and quality of life in FM and CFS.

METHODS

Mixed-methods study based on a randomized clinical trial and qualitative analysis with a descriptive phenomenological approach. The study will be conducted in primary care in Catalonia. The control group will follow the usual clinical practice and the intervention group the usual practice plus the studied intervention (12 hours over 4 days). The intervention based on nutrition, chronobiology and physical exercise will be designed considering participants' opinions as collected in 4 focus groups. To evaluate effectiveness, EuroQol-5D, multidimensional fatigue inventory, VAS pain, Pittsburgh Sleep Quality Index, erMEDAS-17, biological rhythms interview of assessment in neuropsychiatry, REGICOR-Short, FIQR and Hospital Anxiety and Depression Scale questionnaires will be collected at baseline, and at 1, 3, 6, and 12 months post-intervention. Food intake, body composition, resistance and, strength will also be evaluated. The effect size will be calculated using Cohen d and logistic regression models will be used to quantify the impact of the intervention by adjusting for different variables.

DISCUSSION

It expected that the intervention will improve the patients' quality of life, fatigue, pain and insomnia, as well as food and physical exercise habits, providing effectiveness evidence of a new therapy in addressing these syndromes in Primary Heath Care. Improvements in the quality of life will have a positive socioeconomic impact by reducing health expenditure on recurrent medical consultation, medication, complementary medical tests, etc and favor the maintenance of an active working life and productivity.

Effectiveness of a multicomponent exercise training program for the management of delirium in hospitalized older adults using near-infrared spectroscopy as a biomarker of brain perfusion: Study protocol for a randomized controlled trial

Delirium is an important cause of morbidity and mortality in older adults admitted to hospital. Multicomponent interventions targeting delirium risk factors, including physical exercise and mobilization, have been shown to reduce delirium incidence by 30-40% in acute care settings. However, little is known about its role in the evolution of delirium, once established. This study is a randomized clinical trial conducted in the Acute Geriatric Unit of Hospital Universitario de Navarra (Pamplona, Spain). Hospitalized patients with delirium who meet the inclusion criteria will be randomly assigned to the intervention or the control group. The intervention will consist of a multicomponent exercise training program, which will be composed of supervised progressive resistance and strength exercise over 3 consecutive days. Functional Near-Infrared Spectroscopy (NIRS) will be used for assessing cerebral and muscle tissue blood flow. The objective is to assess the effectiveness of this intervention in modifying the following primary outcomes: duration and severity of delirium and functional status. This study will contribute to determine the effectiveness of physical exercise in the management of delirium. It will be the first study to evaluate the impact of a multicomponent intervention based on physical exercise in the evolution of delirium.

Patients' Lived Experience in a Multicomponent Intervention for Fibromyalgia Syndrome in Primary Care: A Qualitative Interview Study

Fibromyalgia syndrome (FMS) disrupts patients' biopsychosocial spheres. A multicomponent intervention (MCI) program, which combined health education, cognitive behavioral therapy, and physical activity, was conducted in South Catalonia's primary care centers with the aim of improving symptom self-management and quality of life. A qualitative interview study was carried out to understand patients' lived experiences during the intervention program. Sampled purposively, 10 patients were interviewed via phone calls and face-to-face. The encounters were audio-recorded, verbatim transcribed, and analyzed through thematic analysis. As a result, four themes emerged: legitimizing fibromyalgia through the MCI, the MCI as a socializing experience, learning how to live with FMS through the MCI, and room for improving the MCI. Participants agreed on the program being an insightful experience that promoted illness knowledge and acceptance and that improved their coping skills and symptom self-management. The inclusion of additional psychological guidance, expressive psychological group therapy, and providing relatives with information were proposed for enhancing the program. Our findings have contributed to gaining insight into the subjective impact of the MCI and identifying new therapeutic targets to tailor the program to patients' needs, which will hopefully increase its effectiveness and improve their quality of life.

Effects of Multicomponent Oriental Integrative Intervention on Cognitive Function, Health Status, Life Satisfaction, and Yangsaeng of Community-Dwelling Elderly

The elderly population in South Korea is rapidly increasing. The elderly living in the community are looking for alternative and complementary methods to improve their healthy longevity and quality of life. This study aimed to examine the effects of Multicomponent Oriental Integrative Intervention on the cognitive function, health status, life satisfaction, and Yangsaeng of the Korean elderly living in the community. A quasi-experimental study design using a pretest-posttest control group was employed. Study participants were a total of 74 elderly (intervention: n = 37, control: n = 37) in Seoul, South Korea. Multicomponent Oriental Integrative Intervention was scheduled to hold two sessions a week, a total of sixteen sessions in 8 weeks, lasting 60 min per session. The measures were the general characteristics of the study participants, the Korean version of the Mini-Mental State Examination (MMSE-K), the Korean health status measure for the elderly, the Korean elderly life satisfaction scale, and the Yangsaeng measurement tool. Data were collected from March 2022 to May 2022. There were statistically significant differences in cognitive function, health status, life satisfaction, and Yangsaeng between the two groups. Multicomponent Oriental Integrative Intervention might be an effective intervention for improving the cognitive function, health status, life satisfaction, and Yangsaeng of the elderly living in the community. Health care providers need to pay attention to Multicomponent Oriental Integrative Intervention for the elderly living in the community.

Patients' appraisals about a multicomponent intervention for fibromyalgia syndrome in primary care: a focus group study

PURPOSE

To assess fibromyalgia patients' experiences and appraisals about a multidisciplinary intervention programme, in Catalonia's primary care, regarding its format and contents, benefits, and health impact in the short and long term.

METHOD

Qualitative interpretative research design through hermeneutic phenomenology perspective. Two focus groups discussions were conducted in February and July 2020. The purposive heterogeneous sample included 19 fibromyalgia patients who attended a multicomponent programme. In addition, thematic analysis on the verbatims was performed.

RESULTS

Findings were organized into five main domains with an explanatory theme each. Overall, the informants valued the programme as a positive experience due to its holistic approach, health benefits, suffering relief, group effect, and fibromyalgia legitimacy promotion. Detected improvable aspects focused on extending the timeframe, including family members as beneficiaries, deepening the thematic contents, and getting regular access to this healthcare service. Furthermore, the intervention was considered feasible to be incorporated into usual clinical care.

CONCLUSION

the programme fulfilled users' expectations about results and procedure and showed promise as a treatment strategy to reinforce the usual practice. Our findings suggest a broad perspective on fibromyalgia patients' suffering, which urges us to adjust the intervention programme to their real health needs.

Quantitative Ultrasound Changes in Echotexture and Functional Parameters after a Multicomponent Training Program in Pre-Frailty Individuals: A Pilot Randomized Clinical Trial

Objective: Currently, ultrasound imaging (USI) is considered a feasible tool in the evaluation of structural and textural muscle differences due to aging. The main aim of this study was to evaluate sonographic changes in muscular structure and function after a 12-week multicomponent training program in pre-frailty individuals. Design: A prospective, randomized, clinical trial was carried out. Participants: Thirty-two pre-frailty subjects were recruited and randomly divided into a multicomponent training program group (n = 16; Multicomponent group) and a conventional care group (n = 14; Control group) with a 12-week follow up. Main outcome measures: Rectus femoris thickness, cross-sectional area (CSA), echointensity, echovariation and vastus lateralis pennation angle tests were carried out to assess the structure and echotexture, and the force-velocity (F-V) profile for muscle power and muscle strength was employed to assess the functional parameters. Results: Statistically significant differences (p < 0.05) were shown for the left rectus femoris echointensity and in the functional parameter of muscle power after a 12-week program for the multicomponent training group compared to the conventional care group. Conclusions: Pre-frailty elderly subjects showed a decrease in rectus femoris echointensity (RF-EI) and an increase in the functional parameter of muscle power after a 12-week multicomponent training program compared to the control group.

Effect of a Multicomponent Intervention on Antihypertensive Medication Intensification in Rural South Asia: Post Hoc Analysis of a Cluster RCT

BACKGROUND

Inadequate treatment of hypertension is a widespread problem, especially in South Asian countries where cardiovascular disease mortality rates are high. We aimed to explore the effect of a multicomponent intervention (MCI) on antihypertensive medication intensification among rural South Asians with hypertension.

METHODS

A post hoc analysis of a 2-year cluster-randomized controlled trial including 2,645 hypertensives aged ≥40 years from 30 rural communities, 10 each, in Bangladesh, Pakistan, and Sri Lanka. Independent assessors collected information on participants' self-reports and physical inspection of medications. The main outcomes were the changes from baseline to 24 months in the following: (i) the therapeutic intensity score (TIS) for all (and class-specific) antihypertensive medications; (ii) the number of antihypertensive medications in all trial participants.

RESULTS

At 24 months, the mean increase in the TIS score of all antihypertensive medications was 0.11 in the MCI group and 0.03 in the control group, with a between-group difference in the increase of 0.08 (95% confidence interval (CI, 0.03, 0.12); P = 0.002). In MCI compared with controls, a greater increase in the TIS of renin-angiotensin-aldosterone system blockers (0.05; 95% CI (0.02, 0.07); P < 0.001) and calcium channel blockers (0.03; 95% CI (0.00, 0.05); P = 0.031), and in the number of antihypertensive medications (0.11, 95% CI (0.02, 0.19); P = 0.016) was observed.

CONCLUSIONS

In rural communities in Bangladesh, Pakistan, and Sri Lanka, MCI led to a greater increase in antihypertensive medication intensification compared with the usual care among adults with hypertension.

A Cluster-Randomised Crossover Pilot Feasibility Study of a Multicomponent Intervention to Reduce Occupational Sedentary Behaviour in Professional Male Employees

Professional male office employees have been identified as those most at risk of prolonged sedentary time, which is associated with many long-term adverse health conditions. The aim of the study was to assess the acceptability and feasibility of a gender-sensitive multicomponent intervention, guided by the socio-ecological model, to reduce occupational sedentary behaviour by increasing physical activity in professional men. The main elements of the intervention comprised: a Garmin watch with associated web-based platform/smartphone application, an under-desk pedal machine, and management participation and support. A cluster-randomised crossover pilot feasibility trial recruiting professional males was conducted in two workplaces. Mixed methods were used to assess the primary outcomes of recruitment, retention, and acceptability and feasibility of the intervention. Secondary outcomes included objectively measured sedentary behaviour, standing and physical activity. Focus groups were used to explore the acceptability of the intervention in a real-world setting. Twenty-two participants were recruited (mean age 42.9 years (SD 11.0)). Recruitment and retention rates were 73.3% and 95%, respectively. Overall, participants found the intervention acceptable and feasible, and expressed enjoyment of the intervention, however desk set-up issues with the pedal devices were noted. The manual recording of the pedalling bouts was overly burdensome. Preliminary data indicate that the intervention may reduce occupational sedentary behaviour and increase physical activity. This intervention should be further tested in a definitive trial following consideration of the findings of this pilot feasibility trial.

A multicomponent psychosocial intervention among people with early-stage dementia involving physical exercise, cognitive stimulation therapy, psychoeducation and counselling: Results from a mixed-methods study

BACKGROUND

There is increasing awareness of the benefits of both physical and psychosocial interventions to empower and benefit people with dementia and their caregivers. However, the potential additional benefits of combining physical and psychosocial interventions have only been sparsely explored. The aim of this pilot study was to investigate the acceptability and potential impact of a multicomponent intervention comprising physical exercise, cognitive stimulation therapy (CST), psychoeducation and counselling for people with early-stage dementia.

DESIGN

A 15-week multicomponent group-based intervention was offered to people with early-stage dementia in Denmark (N = 44). A mixed-methods design combining interviews, observations, tests of cognitive and physical functioning and an interviewer-assisted questionnaire on quality of life was applied to (1) investigate acceptability of the intervention, including whether people with dementia and their caregivers found the intervention meaningful and (2) to explore and assess changes in participants' physical and cognitive functioning and quality of life. The study was conducted between June 2018 and August 2019.

RESULTS

The pilot study demonstrated that the multicomponent intervention was acceptable for people with early-stage dementia and their caregivers. Test results did not show significant changes in measures of participants' physical and cognitive functioning or quality of life. However, qualitative data revealed that participants perceived the intervention as meaningful and found that it had a positive influence on their physical and social well-being. In addition, interaction and support from peers and staff members was considered important and rewarding.

CONCLUSION

This multicomponent intervention constitutes a meaningful and beneficial activity for people with early-stage dementia and their caregivers. It provides an opportunity to engage in social interactions with peers and experience professional support. The study also underlines the importance of providing prolonged and sustainable interventions for people with dementia to maintain personal and social benefits.

Development of a salutogenic intervention for healthy eating among Dutch type 2 diabetes mellitus patients

Healthy eating can be challenging for type 2 diabetes mellitus (T2DM) patients. The theory of salutogenesis, which focuses on the resources required to organize behavioural changes in everyday life, was used to develop an intervention for healthy eating. The aim was to describe the development, structure and content of this salutogenic intervention. The development consisted of two phases that were based on the operationalization of important key principles of salutogenesis. In Phase 1 (Exploration and synthesis), a systematic review and three qualitative studies were performed to explore important characteristics to enable healthy eating in everyday life. The results were used to develop the draft intervention. In Phase 2 (Validation and adjustment), interviews and workshops were conducted with T2DM patients, healthcare providers and scientists. Based on this, the draft intervention was modified into its final form. The developmental process resulted in a 12-week, group-based intervention that aimed to enable important resources for healthy eating via self-examination, reflection, setting goals and sharing experiences. Attention was also paid to disease information, disease acceptance, food literacy, stress management, self-identity and social support. The group sessions began following an individual intake session, with a booster session held 3 months after the intervention. The researcher’s translation of the stakeholders’ priorities into an intervention was corrected for and approved by the stakeholders concerned. This comprehensive salutogenic intervention was developed based on practical and scientific evidence. Providing transparency in developmental processes and content is important because it determines the scientific integrity and credibility of an intervention.

Healthy eating can be difficult for people with the disease type 2 diabetes. This article describes how a programme aimed at helping type 2 diabetes patients to eat healthily was developed. The draft version of the programme was based on a theoretical framework that aims to understand what creates health in everyday life, and on conversations with type 2 diabetes patients and healthcare providers. The draft programme was adjusted based on the feedback of type 2 diabetes patients, healthcare providers and scientists. This resulted in a 12-week, group-based programme that enables people to think about who they are and what they want by setting health goals and sharing experiences. Attention was also paid to disease knowledge, disease acceptance, nutritional skills, dealing with stress, self-identity and social support. The group sessions began following an individual intake session, with a booster session held 3 months after the intervention. By involving everybody, we were able to develop a programme that takes into account the preferences, needs and priorities of all stakeholders. It is important to describe the development and the content of programmes encouraging healthy eating to determine their quality and effectivity.

Theory-Based, Participatory Development of a Cross-Company Network Promoting Physical Activity in Germany: A Mixed-Methods Approach

The untapped potential of workplace health promotion (WHP) in smaller companies and the promising approach to promote physical activity in the workplace requires application-oriented approaches. This study describes the participatory, theory-based development of a cross-company network with a multicomponent intervention for promoting physical activity in smaller companies. The BIG-Manual (from the “Movement as an Investment for Health” project, German—BIG) was the theoretical framework for developing the cross-company network. Qualitative and quantitative data sources were used to identify the requests and requirements of stakeholders (employees on site, local exercise providers, company representatives and network partners) regarding measures promoting physical activity and the cross-company network. The methods applied included two workshops (n = 13; n = 15), individual semi-structured interviews (n = 8) and a survey (n = 285). The analysis revealed that a large number of stakeholders must be taken into consideration for physical activity promotion in cross-company networks. Many similarities between the requests of employees and further stakeholders concerning a multicomponent intervention for promoting physical activity could be identified. Present gender-specific and physical activity-related differences show the importance of target group-specific intervention planning in the context of WHP. This study makes an important contribution for the development of future cross-company networks promoting physical activity and yields valuable information for the design of a multicomponent intervention promoting physical activity.

Participation in an action research project on vaccine services for children: relationship with vaccine delays

Multicomponent interventions are effective in improving vaccine coverage. However, few studies have assessed their effect on timely vaccination. The aim of this study was to compare the proportion of children with vaccine delays at 2- and 12-month visits according to whether or not health centers have participated in an action research project on the organization of vaccination services for 0-5-year-olds. The action research project included a multicomponent intervention and was conducted between 2011 and 2015 in Quebec, Canada. An ecological before/after design was used for this analysis. A total of 264,579 DTaP-IPV-Hib (2-month visits) and 240,541 Men-C-C (12-month visits) vaccine doses were administered during 2011-2012 to 2014-2015 fiscal years, including 19% in 14 participating health centers and the remaining in 78 nonparticipating centers. Vaccine delays demonstrated a more pronounced decreasing trend in participating versus nonparticipating health centers (p < .0001 at 2 and 12 months). Between 2011-2012 and 2014-2015, participating centers managed to eliminate 35% of their vaccine delays at 2-month visits and 33% at 12-month visits, whereas nonparticipating centers eliminated 19% of delays at both visits. Our results are consistent with a positive impact of the multicomponent intervention, despite the fact that it had not specifically aimed at decreasing vaccine delays.

Mindfulness-Based Program Plus Amygdala and Insula Retraining (MAIR) for the Treatment of Women with Fibromyalgia: A Pilot Randomized Controlled Trial

The lack of highly effective treatments for fibromyalgia (FM) represents a great challenge for public health. The objective of this parallel, pilot randomized controlled trial (RCT) was two-fold: (1) to analyze the clinical effects of mindfulness plus amygdala and insula retraining (MAIR) compared to a structurally equivalent active control group of relaxation therapy (RT) in the treatment of FM; and (2) to evaluate its impact on immune-inflammatory markers and brain-derived neurotrophic factor (BDNF) in serum. A total of 41 FM patients were randomized into two study arms: MAIR (intervention group) and RT (active control group), both as add-ons of treatment as usual. MAIR demonstrated significantly greater reductions in functional impairment, anxiety, and depression, as well as higher improvements in mindfulness, and self-compassion at post-treatment and follow-up, with moderate to large effect sizes. Significant decreases in pain catastrophizing and psychological inflexibility and improvements in clinical severity and health-related quality of life were found at follow-up, but not at post-treatment, showing large effect sizes. The number needed to treat was three based on the criteria of ≥50% Fibromyalgia Impact Questionnaire (FIQ) reduction post-treatment. Compared to RT, the MAIR showed significant decreases in BDNF. No effect of MAIR was observed in immune-inflammatory biomarkers (i.e., TNF-α, IL-6, IL-10, and hs-CRP). In conclusion, these results suggest that MAIR, as an adjuvant of treatment-as-usual (TAU), appears to be effective for the management of FM symptoms and for reducing BDNF levels in serum.

Effects of the Preschool-Based Family-Involving DAGIS Intervention Program on Children's Energy Balance-Related Behaviors and Self-Regulation Skills: A Clustered Randomized Controlled Trial

The study examines the effects of a preschool-based family-involving multicomponent intervention on children’s energy balance-related behaviors (EBRBs) such as food consumption, screen time and physical activity (PA), and self-regulation (SR) skills, and whether the intervention effects differed among children with low or high parental educational level (PEL) backgrounds. The Increased Health and Wellbeing in Preschools (DAGIS) intervention was conducted as a clustered randomized controlled trial, clustered at preschool level, over five months in 2017–2018. Altogether, 802 children aged 3–6 years in age participated. Parents reported children’s consumption of sugary everyday foods and beverages, sugary treats, fruits, and vegetables by a food frequency questionnaire, and screen time by a 7-day diary. Physical activity was assessed by a hip-worn accelerometer. Cognitive and emotional SR was reported in a questionnaire by parents. General linear mixed models with and without repeated measures were used as statistical methods. At follow-up, no differences were detected in EBRBs or SR skills between the intervention and control group, nor did differences emerge in children’s EBRBs between the intervention and the control groups when stratified by PEL. The improvement in cognitive SR skills among low PEL intervention children differed from low PEL control children, the significance being borderline. The DAGIS multicomponent intervention did not significantly affect children’s EBRBs or SR. Further sub-analyses and a comprehensive process evaluation may shed light on the non-significant findings.

Effectiveness of a Community-Based Intervention to Increase Supermarket Vendors' Compliance with Age Restrictions for Alcohol Sales in Spain: A Pilot Study

In Spain the legal age to buy alcohol is 18 years. However, official surveys show that minors perceive alcohol availability to be easy. This paper describes the impacts of a community-based intervention to increase vendors' compliance with age limits regarding alcohol sales in supermarkets. The aim of this study was to explore the association between implementation of a multicomponent intervention to reduce adolescents' alcohol use and sale of alcohol to minors in the city of Palma (Spain). Twenty trained adolescents (14-17 years old) conducted 138 alcohol test purchases in nine supermarket chains in August 2018 (baseline; n = 73) prior to the intervention, and again in January 2020 (follow-up; n = 65). Analysis was conducted according to three levels of intervention implemented across the supermarkets: (i) personnel from the supermarkets' Human Resources or Corporate Social Responsibility teams received alcohol service training as trainers (i.e., community mobilization); (ii) managers and vendors training by the capacitated trainers; and (iii) no training of managers or vendors (i.e., control group). In the supermarkets that completed the Training of Trainers and the vendors' training program, average sales decreased significantly from 76.9% in 2018 to 45.5% in 2020, asking for the age of the shopper significantly increased from 3.8% to 45.4%, and asking for proof of age significantly increased from 15.4% to 72.7%. Additionally, a statistically significant increase was observed in the visibility of prohibition to sell alcohol to minors' signs, from 61.5% to 100%. No statistically significant differences were found for the Training of Trainers intervention alone nor in the control group. In conclusion, community mobilization combined with staff training is associated with significant increases in supermarket vendors' compliance with alcohol legislation in Spain.

Reducing falls through the implementation of a multicomponent intervention on a rural mixed rehabilitation ward

PROBLEM

There is an absence of literature to guide staff in how falls can be reduced in a diverse patient population on a mixed acute/subacute rehabilitation unit, especially one with daily fluctuations in acuity that occurs due to frequent changes in its acute/rehabilitation patient ratio.

DESIGN

Pre-intervention and post-intervention audits.

SETTING

The Rehabilitation Unit at Tamworth Rural Referral Hospital in Tamworth, NSW.

KEY MEASURES FOR IMPROVEMENT

Improvement in the number of falls and repeat fallers.

STRATEGIES FOR CHANGE

A multicomponent intervention involving: (a) in-service education sessions for nursing staff about falls risk-increasing drugs, (b) patient and family education regarding falls risks and prevention strategies, (c) improving documentation of incident reports by using a set template, (d) ensuring that the correct patient mobility status information is handed over between nursing shifts and physiotherapists providing timely and regular updates, (e) the introduction of the 'traffic light mobility system' and (f) enhancing the use of existing falls prevention strategies.

EFFECTS OF CHANGE

The total falls reduced in number from 36 falls to 19 with a decrease in the number of repeat fallers from 8 to 4. There was also increased compliance with existing falls risk tools and improved documentation of each falls incident which provided insight into activities and times with higher falls risk.

LESSONS LEARNT

A multicomponent approach remained effective even when applied to a mixed acute/subacute rehabilitation ward setting.

Effectiveness of individual and group multicomponent interventions for smoking cessation in primary care: a quasi-experimental study

BACKGROUND

The efficacy of smoking cessation interventions can be quite diverse in day-to-day clinical practice.

OBJECTIVE

To analyse the effectiveness in smoking cessation of multicomponent interventions carried out in groups or individually in primary care practices.

METHODS

A quasi-experimental, multicentre study of 12-month follow-up of patients treated in multicomponent smoking cessation interventions was carried out in Urban health care centres in Sevilla, Spain. Two hundred and twenty smoking patients, ≥18 years of age, participated either in a multicomponent intervention group (n = 145; mean age 51.7 years; 53.1% women) or in individual interventions (n = 77; mean age 50.5 years; 61.0% women). The abstinence or relapse status was computed from patient self-reports, confirmed by relatives or companions when possible and supplemented by CO-oxymetry tests in 89 patients.

RESULTS

The overall percentage of smoking cessation was 36.9% (37.9% with group and 35.1% with individual intervention, P = 0.398). Patients who quit smoking were younger (48.7 versus 52.9 years old, P < 0.01), with fewer years of smoking (32.9 versus 36.8 years, P < 0.05), with higher education (39.0% versus 25.0%, P < 0.05) and had received pharmacological treatment (91.5% versus 67.9%, P < 0.001). In the multivariate analysis, level of education [odds ratio (OR): 1.995; 95% confidence interval (CI): 1.065-3.735, P < 0.01], group intervention (OR: 1.743; 95% CI: 1.006-3.287, P < 0.05) and drug prescription (OR: 2.368; 95% CI: 1.126-4.980, P < 0.05) were significantly associated with smoking cessation.

CONCLUSIONS

Our study found that multicomponent group and individual interventions in primary care were associated with an overall quit rate of smoking of 36.9% at 12-month follow-up, with higher probability of success among patients with higher education and those who received the group intervention and drug treatment.

Responder Analysis of a Multicomponent Non-Pharmacological Intervention (MAKS) for People With Cognitive Impairment in the German Day-Care Study (DeTaMAKS)

Background: Multicomponent non-pharmacological therapies have been shown to be effective at reducing cognitive symptoms and slowing deterioration in abilities to perform activities of daily living (ADL) in individuals with cognitive impairment. However, little is known about response rates and predictors of response. Methods: We used data from the German day-care study (DeTaMAKS; De = dementia, Ta = Tagespflege/day-care, M = motor stimulation, A = activities of daily living stimulation, K = k/cognitive stimulation, S = social stimulation; n = 362), which was based on a cluster-randomized trial of the non-pharmacological, multicomponent, anti-dementia MAKS therapy for people with cognitive impairment in day-care centers. We investigated response (defined as improvement or no deterioration) for three different response criteria: cognition via Mini-Mental State Examination (MMSE) score, ADL via Erlangen Test of Activities of Daily Living in Persons with Mild Dementia or Mild Cognitive Impairment (ETAM) score, and behavioral and psychological symptoms of dementia (BPSD) via Neuropsychiatric Inventory Questionnaire (NPI-Q) score. In addition, we calculated the number needed to treat (NTT) and response rates according to net gain analyses. Results: For all three criteria, the response rates were higher in the intervention group than in the control group (chi2 test: p = 0.058 to p = 0.003). Compared with non-responders, responders according to cognition had higher ETAM scores (= better ADL abilities) at baseline; responders according to ADL had lower ETAM scores (= poorer ADL abilities) at baseline; and responders according to BPSD had higher NPI-Q scores (= more BPSD) at baseline. Classification rates based on these predictors ranged from 60.6 to 68.3%. Discussion: The response rates to the non-pharmacological MAKS therapy were greater than those reported for anti-dementia drugs. There were only a few differences between responders and non-responders. Because of the low classification rates, these variables had only a small impact on response predictions. Therefore, there are no empirically substantiated selection criteria for the application of MAKS therapy in facilities.

Immediate Intervention Effects of Standardized Multicomponent Group Interventions on People with Cognitive Impairment: A Systematic Review

BACKGROUND

There is no curative medical treatment for dementia. Therefore, researchers turned their attention to non-pharmacological treatment approaches. Many reviews analyzed the efficacy of single-component interventions, but there has been no systematic review of multicomponent interventions so far.

OBJECTIVE

The aim was to systematically review studies using standardized multicomponent group interventions for persons with dementia or persons with mild cognitive impairment (MCI) and to analyze their immediate intervention effects.

METHODS

The databases PubMed, PsycINFO, PSYNDEX, and CINAHL were systematically searched. We included randomized controlled trials with people with MCI or dementia, which implemented interventions with at least two components that targeted different outcome domains. Additionally, the intervention had to be standardized and in a group setting.

RESULTS

Nine studies met the inclusion criteria with a total sample size of N = 513 participants. Six studies applied two, two studies applied three, and one study applied four components. Four studies, which combined at least a physical and a cognitive component, had a positive effect on non-cognitive symptoms of dementia. Two of these interventions additionally had a positive effect on cognitive abilities. One study reported a positive effect on activities of daily living and another study showed an effect on quality of life.

CONCLUSION

In spite of the heterogeneity of the studies, multicomponent interventions suggest a positive effect on non-cognitive symptoms, especially the combination of cognitive and physical components. Single studies had also an effect on additional outcome domains. By trend the effects are dependent on application rate and used assessments.

Multicomponent intervention combining a cognitive stimulation group and tai chi to reduce cognitive decline among community-dwelling older adults with probable dementia: A multi-center, randomized controlled trial

OBJECTIVE

This research study aims to evaluate the effectiveness of a multicomponent intervention that combines a cognitive stimulation group and tai chi to reduce cognitive decline among community-dwelling Chinese older adults with probable dementia.

METHODS

A multi-center, randomized controlled trial design was adopted in this study. In addition to treat as usual, the treatment group (n = 41) participated in a structured cognitive stimulation group followed by tai chi twice a week, with a total of 14 sessions held during the study period. The control group (n = 39) received treat as usual. Mattis Dementia Rating Scale and Mini-Mental State Examination were used for assessing the cognitive abilities of participants in the pre- and post-treatment periods.

RESULTS

A 2 × 2 repeated measures analysis of covariance demonstrated that the treatment group was more effective than the control group on improving Dementia Rating Scale score (F = 7.45, p < .01) with a moderate effect size (partial eta square = .09) and Mini-Mental State Examination score (F = 9.96, p < .01) with a moderate to large effect size (partial eta square = .12) after controlling for age, gender, educational level, marital status, and number of physical illnesses.

CONCLUSION

The present study demonstrates the effectiveness of the multicomponent intervention on improving cognitive ability among community-dwelling older adults with probable dementia, suggesting that the multicomponent intervention can facilitate early identification, assessment, and treatment for community-dwelling older adults with probable dementia.

A Process Evaluation of a Multi-Component Intervention in Dutch Dietetic Treatment to Improve Portion Control Behavior and Decrease Body Mass Index in Overweight and Obese Patients

The SMARTsize intervention embeds an evidence-based portion control intervention in regular dietetic care. This intervention was evaluated to explore (1) which patients participated, (2) the implementation process, and (3) the outcomes of the intervention. The intervention was evaluated with an observational study design including measures at baseline, and three, six, and nine months after the start of the program. Data concerning the process (participation, dose delivered, dose received, satisfaction) and the outcomes (self-efficacy, intention, portion control strategies, and Body Mass Index (BMI) were collected with forms and questionnaires filled out by dietitians and patients. Descriptive analyses, comparison analyses, and cluster analyses were performed. Patients were mainly obese, moderately to highly educated women of Dutch ethnicity. Use of the intervention components varied from 50% to 100% and satisfaction with the SMARTsize intervention was sufficient to good (grades 7.2⁻8.0). Statistically significant (p < 0.001) improvements were observed for self-efficacy (+0.5), portion control strategies (+0.7), and BMI (-2.2 kg/m²), with no significant differences between patients with or without counselling. Three clusters of patients with different levels of success were identified. To conclude, implementing an evidence-based portion control intervention in real-life dietetic practice is feasible and likely to result in weight loss.

The Effectiveness of a PRoactive Multicomponent Intervention Program on Disability in Independently Living Older People: A Randomized Controlled Trial

BACKGROUND

There is an increase in functional limitations and a decline in physical and mental well-being with age. Very few effective lifestyle interventions are available to prevent adverse outcomes such as disability in (pre-) frail older people. The effectiveness of an interdisciplinary multicomponent intervention program to prevent disability in older people in the community was tested.

METHOD

A randomized controlled trial (RCT) with a one-year follow-up was conducted in the Netherlands. Community-dwelling pre-frail older people aged 65 years and over were invited to participate. Frailty was measured with the Groningen Frailty Indicator (GFI) and categorized into non-frail (GFI=0), pre-frail (GFI = 1-3) and frail (GFI ≥ 4). The intervention program consisted of four components: a medication review, physical fitness, social skills, and nutrition.

OUTCOMES

The primary outcome was activity of daily living (ADL) measured with the Katz-6. Secondary outcomes were quality of life (SF-12) and healthcare consumption such as hospital admission, nursing home admission and primary care visits. Additional outcomes measured in the intervention group were physical fitness, Instrumental Activities of Daily Living (IADL), muscle strength, walking speed, functional capacity, mobility, feelings of depression and loneliness and nutritional status. The data were collected at baseline, after each intervention component and at a 12-month follow-up. An intention to treat analysis was used.

RESULTS

In total, there were 290 participants, and 217 (74.8%) completed the study. The mean age was 74 (SD: 7.2), most were pre-frail (59.9%), the majority were female (55.2%), and the individuals were not living alone (61.4%). After the 12-month follow-up, the median Katz-6 score did not change significantly between the two groups; adjusted Odds Ratio (OR) = 0.96 (95% Confidence Interval (CI): 0.39-2.35, p-value 0.92). No statistically significant differences were observed between the groups for quality of life and healthcare consumption. Among the participants in the intervention group, IADL (Friedman's test p <=0.04, X2 =6.50), walking speed (Friedman's test p <0.001, X2 =19.09) and functional capacity (Friedman's test p <0.001, X2 =33.29) improved significantly after the one-year follow-up. Right-hand grip strength improved immediately after completion of the intervention (Wilcoxon signed-rank test p=0.00, z= -3.39) but not after the 12-month follow-up.

CONCLUSION

The intervention program did not significantly improve daily functioning, quality of life and healthcare consumption among (pre) frail community-dwelling older persons at the one-year follow-up. Participants in the intervention group experienced improvements in walking speed, functional capacity and instrumental activities of daily living. More research is needed to better understand why may benefit and how to identify the target population.

The ASCENT (Allocation System Changes for Equity in Kidney Transplantation) Study: a Randomized Effectiveness-Implementation Study to Improve Kidney Transplant Waitlisting and Reduce Racial Disparity

INTRODUCTION

The United Network for Organ Sharing (UNOS) implemented a new Kidney Allocation System (KAS) in December 2014 that is expected to substantially reduce racial disparities in kidney transplantation among waitlisted patients. However, not all dialysis facility clinical providers and end stage renal disease (ESRD) patients are aware of how the policy change could improve access to transplant.

METHODS

We describe the ASCENT (Allocation System Changes for Equity in KidNey Transplantation) study, a randomized controlled effectiveness-implementation study designed to test the effectiveness of a multicomponent intervention to improve access to the early steps of kidney transplantation among dialysis facilities across the United States. The multicomponent intervention consists of an educational webinar for dialysis medical directors, an educational video for patients and an educational video for dialysis staff, and a dialysis-facility specific transplant performance feedback report. Materials will be developed by a multidisciplinary dissemination advisory board and will undergo formative testing in dialysis facilities across the United States.

RESULTS

This study is estimated to enroll ~600 U.S. dialysis facilities with low waitlisting in all 18 ESRD Networks. The co-primary outcomes include change in waitlisting, and waitlist disparity at 1 year; secondary outcomes include changes in facility medical director knowledge about KAS, staff training regarding KAS, patient education regarding transplant, and a medical director's intent to refer patients for transplant evaluation.

CONCLUSION

The results from the ASCENT study will demonstrate the feasibility and effectiveness of a multicomponent intervention designed to increase access to the deceased-donor kidney waitlist and reduce racial disparities in waitlisting.

Effectiveness and cost-effectiveness of knowledge transfer and behavior modification interventions in type 2 diabetes mellitus patients--the INDICA study: a cluster randomized controlled trial

BACKGROUND

Type 2 diabetes mellitus is a chronic disease whose health outcomes are related to patients and healthcare professionals' decision-making. The Diabetes Intervention study in the Canary Islands (INDICA study) aims to evaluate the effectiveness and cost-effectiveness of educational interventions supported by new technology decision tools for type 2 diabetes patients and primary care professionals in the Canary Islands.

METHODS/DESIGN

The INDICA study is an open, community-based, multicenter, clinical controlled trial with random allocation by clusters to one of three interventions or to usual care. The setting is primary care where physicians and nurses are invited to participate. Patients with diabetes diagnosis, 18-65 years of age, and regular users of mobile phone were randomly selected. Patients with severe comorbidities were excluded. The clusters are primary healthcare practices with enough professionals and available places to provide the intervention. The calculated sample size was 2,300 patients. Patients in group 1 are receiving an educational group program of eight sessions every 3 months led by trained nurses and monitored by means of logs and a web-based platform and tailored semi-automated SMS for continuous support. Primary care professionals in group 2 are receiving a short educational program to update their diabetes knowledge, which includes a decision support tool embedded into the electronic clinical record and a monthly feedback report of patients' results. Group 3 is receiving a combination of the interventions for patients and professionals. The primary endpoint is the change in HbA1c in 2 years. Secondary endpoints are cardiovascular risk factors, macrovascular and microvascular diabetes complications, quality of life, psychological outcomes, diabetes knowledge, and healthcare utilization. Data is being collected from interviews, questionnaires, clinical examinations, and records. Generalized linear mixed models with repeated time measurements will be used to analyze changes in outcomes. The cost-effectiveness analysis, from the healthcare services perspective, involves direct medical costs per quality-adjusted life year gained and two periods, a 'within-trial' period and a lifetime Markov model. Deterministic and probabilistic sensitivity analyses are planned.

DISCUSSION

This ongoing trial aims to set up the implementation of evidence-based programs in the clinical setting for chronic patients.

[Effectiveness of advanced group and individual interventions in tackling tobacco dependency in primary care]

OBJECTIVES

To compare the effectiveness of group advanced intervention and individual advanced intervention for smoking management in primary health care; b) to know if in group intervention exists an added positive effect due of the group and, if this is true, to characterize it; and c) to know the advantages and inconvenients that the participants attribute to each intervention.

DESIGN

Control clinic trial randomized in individual scale.

SETTING

Mallorca primary health centers, Spain.

PARTICIPANTS

Smokers >5 packet-year or monoxid carbon levels >15 ppm prepared for give up smoking. People younger than 18 years, people with terminal illness, and mental problems will be excluded.

INTERVENTIONS

Candidates will be assigned to: a) group intervention; b) individual intervention; or c) short intervention or control group. Interventions will be done by a nurse and a general practitioner. Depth interview will be done for qualitative study. PRINCIPAL MEASUREMENT: Maintained cessation during 12 months confirmed by expired-air carbon monoxide measurement. SECONDARY MEASUREMENTS: Self-declared cessation and confirmed by expired-air carbon monoxide measurement months 1, 2, 3, 6, and 9, and tobacco reduction if there isn't abandonment.

ANALYSIS

Intention treatment. Multilevel analysis will be done to determinate the positive effect added of the group if it's proved that exists. Content analysis for qualitative study.

DISCUSSION

Randomization will prevent participants will be treated by their general practitioner o their nurse, this can mean worse results than results obtained in practice.
