Reducing Unnecessary Testing Without Harming Patient Outcomes

MedicalResearch.com: What is the background for this study?
Response: It is well known that a significant portion of healthcare activities is considered of low-value. Eliminating such low-value care is often targeted in efforts to both contain rapidly increasing healthcare costs as well as maintain high-quality care.
In this context, our study focused on reducing unnecessary laboratory testing. In 2008, our study group performed a multifaceted intervention aimed at reducing unnecessary diagnostic testing at the Internal Medicine department of the Amsterdam University Medical Center, location Vrije Universiteit (VU).
In the ‘Reduction of Unnecessary Diagnostics Through Attitude Change of the Caregivers’, we implemented this successful intervention in the Internal Medicine departments of four large teaching hospitals in the Netherlands. The intervention included creating awareness through education and feedback, intensified supervision of residents, and changes in order entry systems.

MedicalResearch.com: What is the background for this study?
Response: Plant-based diets have really grown in popularity in the last several years, particularly among the younger generation in the United States, many of whom are adopting a plant-based or vegetarian/vegan diet. However, the quality of such a diet can vary drastically. While many prior studies have demonstrated beneficial associations for risk of type 2 diabetes with healthful plant-based foods such as fruits, vegetables, nuts/seeds, whole grains, and legumes, the opposite is true for less healthful plant-based foods such as potatoes and refined grains such as white rice. In addition, some animal-based foods, such as dairy and fish, have shown protective associations against the development of type 2 diabetes, so strict vegetarian diets which exclude these foods may miss out on the potential benefits.
Given these divergent findings, we sought to pool all the available data from prior cohort studies to analyze whether the overall association of a diet which emphasizes plant-based foods (both healthful and unhealthful) are related to risk of type 2 diabetes.
