M.W. Langendam PhD (Evidence synthesis methodology: making sense of evidence)
The research line is largely based on the conceptual framework of the GRADE (Grading Recommendations Assessment, Development and Evaluation) approach. GRADE provides a patient-centred framework to present evidence summaries, to assess and rate the certainty of evidence, to move from evidence to recommendation and to grade the strength of recommendations (www.gradeworkinggroup.org). Adopted by many evidence synthesis and guideline development organisations, GRADE is considered the state of the art methodology to develop evidence-based clinical practice guidelines. Her current research aims to contribute to further development of GRADE, e.g. by applying GRADE to different domains (diagnosis, preclinical animal studies, environmental health) and different types of decisions (clinical management, coverage decisions). Evaluating the use of GRADE, implementing GRADE in the Netherlands, consultation and training are also part of Miranda's work.
The main research theme for the coming years is to develop and appraise methods for linking and interpreting different types of evidence and evidence streams. This is particularly relevant in the evaluation of medical tests, where direct evidence on the clinical utility is scarce. Together with the Biomarkers and Test Evaluation (BiTE) program, led by professor Patrick Bossuyt, development of guideline methodology with regard to recommendations about medical tests is a high priority topic. More general, the research line is targeted to improving the quality of systematic reviews and clinical and public health guidelines.
Miranda's work is characterized by a high level of collaboration on local, national and international level (e.g. Health Care Institute (Zorginstituut Nederland), McMaster University, Cochrane, GRADE working group). First of all because a methodologist needs content experts to do meaningful work, but also because evidence synthesis is a rapidly evolving research field and a study design that is often used. At the AMC she is collaborating with colleagues from several departments. The aim for the coming years is to formalize collaboration (e.g. joint grant proposals, PhD students and post-docs), and – with regard to the alliance – to explore collaboration with VUmc (e.g. APH Methodology).
