New Technology in Trauma is technological advances in diagnostic tests that are found in hospitals are now poised to appear in primary care. Many of these advances have occurred because of the speed, size and range of devices that can provide accurate measurements of a wide range of biochemical, microbiological, and hematological parameters. Glucometers transformed the speed and ease of obtaining accurate blood glucose levels, and urine dipsticks removed the need for microscopy in many patients. Advances in electronics have also made in-roads into general practice, with cheap and generally accurate blood pressure devices now widely available both in the practice and at home.  Evidence-based medicine (EBM) is a form of medicine that aims to optimize decision-making by emphasizing the use of evidence from well designed and conducted research. The term was originally used to describe an approach to teaching the practice of medicine and improving decisions by individual physicians.
