The accelerating pace of technological advancements and the digitization of healthcare have reshaped the landscape of medical device evaluation. Unlike pharmaceuticals, medical devices often undergo continuous iterations, rely heavily on user expertise, and have shorter life cycles. This dynamic environment demands rigorous, transparent, and tailored evidence assessment methodologies.
In this White Paper, MTRC addresses key challenges in conducting systematic literature reviews for medical devices and provides actionable solutions for industry leaders:
Scarcity of Randomized Controlled Trials (RCTs): Traditional evidence hierarchies fall short due to the limited availability of RCTs in MedTech. We advocate for adopting flexible approaches that integrate case series and cohort studies, providing a more comprehensive evidence base.
Device–User Interaction: Clinical outcomes are often influenced by operator expertise. MTRC proposes employing subgroup analyses and advanced statistical techniques to quantify the impact of learning curves and user variability.
Diverse Study Designs: Bias inherent in before-and-after studies, cohort studies, and case series can obscure clinical insights. The White Paper recommends robust techniques such as meta-regression, sensitivity analysis, and narrative synthesis to ensure credible conclusions.
Variations in Methodological Quality: Standardized tools for bias assessment are lacking in medical device evaluations, increasing the risk of misleading outcomes. We highlight best practices using established frameworks like the Cochrane Risk of Bias Tool and ROBINS-I for more reliable assessments.
Limited Peer-Reviewed Publications: Abstracts and conference proceedings often present incomplete or non-peer-reviewed data. MTRC underscores the importance of meticulous documentation and cautious interpretation when incorporating these sources.
Device Generations and Technological Evolution: Continuous advancements in device design challenge evidence comparability. We emphasize the need for data analysis by device generation and narrative synthesis for sharper insights.
Complexities in Diagnostic Test Accuracy Studies: Variability in study designs (e.g., case-control versus cross-sectional) complicates diagnostic assessments. Our White Paper offers guidance on segregated analyses and meta-analysis techniques to manage heterogeneity.
By addressing these critical challenges, MTRC empowers stakeholders in the medical technology sector to navigate the complexities of evidence assessment confidently. Our insights ensure that your teams can make more informed, evidence-based decisions that align with the dynamic realities of MedTech innovation.
