Assessing abdominal pain in adults: a rational, cost-effective, and evidence-based strategy

The management of abdominal pain has changed significantly in the past 20 years, with increasing emphasis on identifying patients who are at high risk for occult pathology and worse outcomes. Emphasizing safe disposition over diagnosis, this issue identifies the important aspects of the history and physical examination, explores strengths and weaknesses of laboratory evaluations, and summarizes the pros and cons of the many types of imaging now available. With abdominal pain still the most common chief complaint seen in the emergency department, a new look at the evolution of assessment strategies is in order, such as new recommendations on the use of oral contrast, managing HIV patients on highly active antiretroviral therapy, maximizing use of bedside ultrasound, when and how to offer pain relief, and the value of serial examinations and observation to reduce costs and improve care.
