It Is Not That Simple nor Compelling!; Comment on “Translating Evidence Into Healthcare Policy and Practice: Single Versus Multi-faceted Implementation Strategies – Is There a Simple Answer to a Complex Question?”
Healthcare decisions are often made under pressure, with varying levels of information in a changing clinical context. With limited resources and a focus on improving patient outcomes, healthcare managers and health professionals strive to implement both clinical and cost-effective care. However, the gap between research evidence and health policy/clinical practice persists despite our best eff...
متن کاملAnalysis and comment Health services research Process evaluation in randomised controlled trials of complex interventions
“Complex interventions” are health service interventions that are not drugs or surgical procedures, but have many potential “active ingredients.” A complex intervention combines different components in a whole that is more than the sum of its parts. Randomised controlled trials (RCTs) are the most rigorous way to evaluate the effectiveness of interventions, regardless of their complexity. Becau...
متن کاملExamining the use of process evaluations of randomised controlled trials of complex interventions addressing chronic disease in primary health care—a systematic review protocol
BACKGROUND Randomised controlled trials (RCTs) of complex interventions in primary health care (PHC) are needed to provide evidence-based programmes to achieve the Declaration of Alma Ata goal of making PHC equitable, accessible and universal and to effectively address the rising burden from chronic disease. Process evaluations of these RCTs can provide insight into the causal mechanisms of com...
متن کاملProcess evaluations for cluster-randomised trials of complex interventions: a proposed framework for design and reporting
BACKGROUND Process evaluations are recommended to open the 'black box' of complex interventions evaluated in trials, but there is limited guidance to help researchers design process evaluations. Much current literature on process evaluations of complex interventions focuses on qualitative methods, with less attention paid to quantitative methods. This discrepancy led us to develop our own frame...
متن کاملEvaluation of Clinical Trials
In a number of important clinical issues such as evaluation of the efficacy or effectiveness of therapeutic or preventive interventions as well as for comparing the harms of interventions, randomized controlled trials (RCTs) provide the highest levels of evidence, either directly or indirectly. It is obvious that critical appraisal of these studies to assess their validity and precision is of p...
