Dr. Nieuwlaat’s research focuses on better understanding gaps and barriers to optimal care. He tests interventions to improve the application of guideline recommended care and consequently cardiovascular outcomes. For this, he has performed observational studies assessing the quality of care for atrial fibrillation patients and, systematic reviews to summarize barriers to care and the effects of knowledge translation intervention techniques to improve the uptake of recommended care. He also conducted cluster randomized trials testing interventions to improve the uptake of recommended atrial fibrillation care.
