A review of reporting of participant recruitment and retention in RCTs in six major journals

<p>Abstract</p> <p>Background</p> <p>Poor recruitment and retention of participants in randomised controlled trials (RCTs) is problematic but common. Clear and detailed reporting of participant flow is essential to assess the generalisability and comparability of RCTs. Despite improved reporting since the implementation of the CONSORT statement, important problems remain. This paper aims: (i) to update and extend previous reviews evaluating reporting of participant recruitment and retention in RCTs; (ii) to quantify the level of participation throughout RCTs.</p> <p>Methods</p> <p>We reviewed all reports of RCTs of health care interventions and/or processes with individual randomisation, published July–December 2004 in six major journals. Short, secondary or interim reports, and Phase I/II trials were excluded. Data recorded were: general RCT details; inclusion of flow diagram; participant flow throughout trial; reasons for non-participation/withdrawal; target sample sizes.</p> <p>Results</p> <p>133 reports were reviewed. Overall, 79% included a flow diagram, but over a third were incomplete. The majority reported the flow of participants at each stage of the trial after randomisation. However, 40% failed to report the numbers assessed for eligibility. Percentages of participants retained at each stage were high: for example, 90% of eligible individuals were randomised, and 93% of those randomised were outcome assessed. On average, trials met their sample size targets. However, there were some substantial shortfalls: for example 21% of trials reporting a sample size calculation failed to achieve adequate numbers at randomisation, and 48% at outcome assessment. Reporting of losses to follow up was variable and difficult to interpret.</p> <p>Conclusion</p> <p>The majority of RCTs reported the flow of participants well after randomisation, although only two-thirds included a complete flow chart and there was great variability over the definition of "lost to follow up". Reporting of participant eligibility was poor, making assessments of recruitment practice and external validity difficult. Reporting of participant flow throughout RCTs could be improved by small changes to the CONSORT chart.</p

Walking on common ground: a cross-disciplinary scoping review on the clinical utility of digital mobility outcomes

Physical mobility is essential to health, and patients often rate it as a high-priority clinical outcome. Digital mobility outcomes (DMOs), such as real-world gait speed or step count, show promise as clinical measures in many medical conditions. However, current research is nascent and fragmented by discipline. This scoping review maps existing evidence on the clinical utility of DMOs, identifying commonalities across traditional disciplinary divides. In November 2019, 11 databases were searched for records investigating the validity and responsiveness of 34 DMOs in four diverse medical conditions (Parkinson’s disease, multiple sclerosis, chronic obstructive pulmonary disease, hip fracture). Searches yielded 19,672 unique records. After screening, 855 records representing 775 studies were included and charted in systematic maps. Studies frequently investigated gait speed (70.4% of studies), step length (30.7%), cadence (21.4%), and daily step count (20.7%). They studied differences between healthy and pathological gait (36.4%), associations between DMOs and clinical measures (48.8%) or outcomes (4.3%), and responsiveness to interventions (26.8%). Gait speed, step length, cadence, step time and step count exhibited consistent evidence of validity and responsiveness in multiple conditions, although the evidence was inconsistent or lacking for other DMOs. If DMOs are to be adopted as mainstream tools, further work is needed to establish their predictive validity, responsiveness, and ecological validity. Cross-disciplinary efforts to align methodology and validate DMOs may facilitate their adoption into clinical practice

Selbstmanagementförderung bei chronischer Krankheit für Menschen mit Migrationshintergrund – ein Gruppenkurs mit Peer-Ansatz als Beitrag zu gesundheitlicher Chancengerechtigkeit

Ziel: Begrenzte Gesundheits- und Sprachkompetenz erschweren Menschen mit Migrationshintergrund (MmM) den Zugang zu Gesundheitsinformationen und -versorgung, gerade bei chronischer Krankheit. Bei der Einführung eines Peer-geleiteten Stanford Selbstmanagementkurses bei chronischer Krankheit wurde in der Schweiz großes Interesse und hohe Motivation von MmM beobachtet. Daher wurde eruiert, ob das Kursprogramm auf Deutsch bei moderaten Sprachkenntnissen umsetzbar ist. Methodik: Dies ist der explorative Teil der Begleitstudie zur Einführung des Stanford Programms in der Schweiz und im deutschsprachigen Europa. Angelehnt an Prinzipien der Grounded Theory wurden leitfadengestützte Fokusgruppen- und Einzelinterviews mit Kursteilnehmerinnen, -leiterinnen und -koordination (n=30) geführt, die thematisch ausgewertet wurden. Im Fokus der Datenerhebung standen die Durchführbarkeit, Zufriedenheit und Kursinhalte. Ergebnisse: Der Kurs stößt bei MmM auf positive Resonanz und scheint auf Deutsch prinzipiell durchführbar zu sein, hohe Alltagsrelevanz zu haben sowie Impulse zur Integration zu setzen. Schlussfolgerung: Zu prüfen ist ein weiterer Anpassungsbedarf auf den Migrationskontext, um den Kurs vulnerablen Gruppen besser zugänglich zu machen. Aim: Limited health literacy and language skills are barriers for people with a migrant background (PMB) to access health information and healthcare services, in particular for those living with chronic conditions. During the introduction of a peer-led Stanford chronic disease self-management course in Switzerland, special interest in the program as well as motivation of PMB was observed. In response, we examined if the program can be implemented in German for people with limited language skills. Methods: This explorative study is part of the evaluation study on introducing the adapted Stanford program in Switzerland and German-speaking Europe. Following the principles of Grounded Theory, semi-structured focus group and individual interviews were conducted with course participants, leaders and coordinators (n=30) and analyzed thematically. The focus was on the feasibility, satisfaction and course content. Results: In principle, the program seems to have positive value for PMB, may work for them in German, have high relevance for everyday life and give an impetus for social integration. Conclusion: The need for and extent of modification of the program for PMB has to be further explored in order to make it more accessible for vulnerable groups

Trinkerszenen im öffentlichen Raum: ein Städtevergleich.

Ein ethnographischer Vergleich von Trinkerszenen in fünf Schweizer Städten zeigt eine zunehmende Reglementierung und konsumorientierte Ökonomisierung des öffentlichen Raums und entsprechende Ausgrenzungsmechanismen gegenüber den sich dort aufhaltenden Gruppen. Die Politik der Städte weist jedoch auch erhebliche Unterschiede auf
