Direct observation in medical education: a review of the literature and evidence for validity.
In 2000, the Accreditation Council for Medical Education introduced a new initiative that substantively changed the method by which residency programs are evaluated. In this new competency-based approach to residency education, assessment of performance became a main area of interest, and direct observation was offered as a tool to assess knowledge and skills. Despite being an inherent part of medical education as faculty and learners work together in clinical experiences, direct observation has traditionally been an informal and underused assessment method across all specialties. ⋯ Assessing learners in natural settings offers the opportunity to see beyond what they know and into what they actually do, which is fundamentally essential to training qualified physicians. Although the literature identifies several threats to its validity as an assessment, it also demonstrates methods to minimize those threats. Based on the current recommendations and need for performance assessment in education and with attention paid to the development and design, direct observation can and should be included in medical education curricula.

Medical schools and residencies are currently facing a shift in their teaching paradigm. The increasing amount of medical information and research makes it difficult for medical education to stay current in its curriculum. As patients become increasingly concerned that students and residents are "practicing" on them, clinical medicine is becoming focused more on patient safety and quality than on bedside teaching and education. ⋯ Only a few studies have shown direct improvements in clinical outcomes from the use of simulation for training. Multiple studies have demonstrated the effectiveness of simulation in the teaching of basic science and clinical knowledge, procedural skills, teamwork, and communication as well as assessment at the undergraduate and graduate medical education levels. As simulation becomes increasingly prevalent in medical school and resident education, more studies are needed to see if simulation training improves patient outcomes.

Teamwork has become a major focus in healthcare. In part, this is the result of the Institute of Medicine report entitled To Err Is Human: Building a Safer Health System, which details the high rate of preventable medical errors, many of which are the result of dysfunctional or nonexistent teamwork. It has been proposed that a healthcare system that supports effective teamwork can improve the quality of patient care and reduce workload issues that cause burnout among healthcare professionals. ⋯ Much of this work has been done in fields in which medical professionals deal with crisis situations (ie, anesthesia, trauma, and labor and delivery). We describe the current programs for teaching medical students these essential skills and what recommendations have been made about the best ways to introduce teaching this skill set into the curriculum. Finally, we include a review on assessing teamwork because one cannot teach team training without implementing an assessment to ensure that the skills are being learned.

Type 2 diabetes mellitus is a multifactorial metabolic disorder. It is characterized by chronic hyperglycemia, insulin resistance, and a relative insulin secretion defect. The prevalence of type 2 diabetes mellitus has risen worldwide in large part because of an increase in obesity and sedentary lifestyles. ⋯ The evolving understanding about the influence of the incretin effect, insulin signal transduction, adipose tissue, intra-islet cell communication, and inflammation is changing the way in which we view type 2 diabetes mellitus. This new understanding will eventually provide us with new treatment approaches to help patients who have type 2 diabetes mellitus. This article gives a review of the current and emerging concepts of the pathophysiology of type 2 diabetes mellitus.

The incretins have emerged as key targets in the modern treatment of type 2 diabetes mellitus. Understanding the physiology of the incretins is essential to the physician's ability to appropriately use emerging pharmacotherapies that target this system. This review describes incretin physiology and discusses recent trials of drugs that modulate this system in the treatment of type 2 diabetes. ⋯ As the articles show, new medications manipulating the incretin system are an important part of treating type 2 diabetes. The cost of these drugs and their potential side effects in comparison with existing agents must be considered when they are being selected as part of a treatment regimen. However, the evidence to date offers much promise and enthusiasm.
