Recruitment, retention, and adherence of family caregivers: Lessons from a multisite trial / Reclutamiento, retención y adherencia de los cuidadores familiares: Lecciones de un ensayo clínico multi-sitio / Recrutamento, retenção e adesão de cuidadores familiares: lições de um estudo clínico multi-site

Objective. To describe the recruitment, retention of family caregivers, and adherence to a telephone based intervention evaluated in a multi-site trial and provide recommendations for the design of future studies. Methods.A descriptive study based on a secondary analysis of a multi-site clinical development in Colombia and Brazil. Recruitment was measured by the number of participants eligible and consented. Retention was assessed by the percentage of participants with outcomes data at two follow-ups. The intervention adherence was measured by the percentage of the caregiver who received the intervention. Results. Of the family caregivers assessed, 63% were eligible, and 32.9% declined to be in the study for time restriction or no interest. In Colombia, the total retention rate of caregivers was 63.4% at the first follow-up and 48% at the second follow-up, while in Brazil was Invest Educ Enferm. 2023; 41(2): e04Recruitment, retention, and adherence of family caregivers:Lessons from a multisite trialde 52.8% and 46.2%, respectively. At the end of the study, the sample comprised 28 and 70 caregivers in the intervention and control groups, respectively, for a retention rate of 47%. Of 104 family caregivers allocated to the intervention group, 42 (40.3%) received five sessions. Most reported not completing the Caregiver's Activity Diary. Conclusion.The recruitment of family caregivers, participant retention, and adherence to the telephone intervention was unsuccessful. Future studies should apply an assessment tool during the recruitment of family caregivers and replace the term "caregiver" with "care provider" in the material involved in the research; define a retention protocol before starting the study and involve family caregivers in the design of the interventions

La adherencia a la intervención se determinó por el porcentaje de cuidadores que recibieron la intervención. Resultados. De los cuidadores familiares evaluados, 63% fueron elegibles, y 32.9% declinaron participar en el estudio por restricción de tiempo o falta de interés. En Colombia, la tasa de retención total de cuidadores fue de 63.4% en el primer seguimiento y de 48% en el segundo, mientras que en Brasil fue de 52.8% y 46.2%, respectivamente.

Practice based research in dentistry: an alternative to deal with clinical questions

Abstract Clinical interventions in dental practice should be determined based on the best scientific evidence available. Well-designed randomized clinical trials (RCTs) provide important evidence supporting the efficacy of interventions and are usually considered as the best primary evidence. However, the strict criteria adopted by most RCTs reduce their external validity since some findings from these studies might not work under usual conditions. On the other hand, practice-based research (PBR) studies have been designed to better define the effectiveness of clinical interventions under settings closer to "real-world" conditions. Therefore, this review aimed to describe different PBR designs discussing some advantages and limitations of such studies. The stimulus to organization PBR networks is discussed since the studies performed by these networks involve large number of clinicians and important conclusions can be drawn. Designs of observational studies including surveys and cohort studies based on practice are presented. Survey methods are important to know the behavior of practitioners regarding diagnostic and decision of treatment. Cohorts allow assessing different cofounders contributing to some outcome since large sample sizes and long follow-up periods can be observed in some of these studies. Pragmatic trials designed to take place in real-world clinical practice settings are also discussed as a useful design to assess the effectiveness of clinical interventions. In conclusion, this review sought to present PBR studies as alternative designs to answer clinical questions, but not replacing randomized clinical trials.

Clinicoepidemiological research designs in childhood allergic diseases

Clinical epidemiology is defined as a method for investigating the distribution and determinants of diseases and for applying this knowledge in their prevention, and simply means application of epidemiological methods for medical research. In evidence-based medicine, randomized controlled trials (RCT) are the gold standard for assessing efficacy and safety of the intervention, while it is commonly impractical because of many limitations, such as ethical/legal problems and weak external-validity. High internal-validity of RCT permits to assess the direct efficacy of intervention without interference with bias and confounder; however, it has less generalizability or applicability to the real-life practice. Evidence-based practical guidelines are developed for patient management and decision making in real-life practice; paradoxically, the evidence of the guidelines does not come from real life, but from strict trial life. To overcome these limitations, pragmatic clinical trials for assessing the effectiveness of intervention in real-life practice or high-quality observational studies would be the best alternatives or could add more strong evidence. This article provides an overview of clinicoepidemiological research designs in the field of childhood allergic diseases and their strength/weakness.
