Randomized Controlled Trial
Healthy Children, Strong Families 2: A randomized controlled trial of a healthy lifestyle intervention for American Indian families designed using community-based approaches.
Background/Aims Few obesity prevention trials have focused on young children and their families in the home environment, particularly in underserved communities. Healthy Children, Strong Families 2 is a randomized controlled trial of a healthy lifestyle intervention for American Indian children and their families, a group at very high risk of obesity. The study design resulted from our long-standing engagement with American Indian communities, and few collaborations of this type resulting in the development and implementation of a randomized clinical trial have been described. ⋯ Conclusion This multisite intervention addresses key gaps regarding family/home-based approaches for obesity prevention in American Indian communities. Healthy Children, Strong Families 2's innovative aspects include substantial community input, inclusion of both traditional (diet/activity) and less-studied obesity risk factors (stress/sleep), measurement of both adult and child outcomes, social networking support for geographically dispersed households, and a community selected active control group. Our data will address a literature gap regarding multiple risk factors and their relationship to health outcomes in American Indian families.

Randomized Controlled Trial Pragmatic Clinical Trial
PRagmatic trial Of Video Education in Nursing homes: The design and rationale for a pragmatic cluster randomized trial in the nursing home setting.
Background/Aims Nursing homes are complex healthcare systems serving an increasingly sick population. Nursing homes must engage patients in advance care planning, but do so inconsistently. Video decision support tools improved advance care planning in small randomized controlled trials. ⋯ Conclusion We must rigorously evaluate interventions to deliver more patient-focused care to an increasingly frail nursing home population. Video decision support is a practical approach to improve advance care planning. PRagmatic trial Of Video Education in Nursing homes has the potential to promote goal-directed care among millions of older Americans in nursing homes and establish a methodology for future pragmatic randomized controlled trials in this complex healthcare setting.

Evidence suggests that patients are generally accepting of their enrollment in trials for emergency care conducted under exception from informed consent. It is unknown whether individuals with more severe initial injuries or worse clinical outcomes have different perspectives. Determining whether these differences exist may help to structure post-enrollment interactions. ⋯ Patients and surrogates of patients with unfavorable clinical outcomes were somewhat less accepting of their own inclusion in the Progesterone for the Treatment of Traumatic Brain Injury trial under exception from informed consent than were patients or surrogates of patients with favorable clinical outcomes. These findings suggest a need to identify optimal strategies for communicating with patients and their surrogates regarding exception from informed consent enrollment when clinical outcomes are poor.

Meta-analyses are frequently performed on adverse event data and are primarily used for improving statistical power to detect safety signals. However, in the evaluation of drug safety for New Drug Applications, simple pooling of adverse event data from multiple clinical trials is still commonly used. We sought to propose a new Bayesian hierarchical meta-analytic approach based on consideration of a hierarchical structure of reported individual adverse event data from multiple randomized clinical trials. ⋯ Our proposed meta-analysis models considered trial effects to avoid confounding by trial and borrowed strength from both within and across body systems to obtain reasonable and stable estimates of an effect measure by considering a hierarchical structure of adverse events.
