Reports of "satisfactory relief" by IBS patients receiving usual medical care are confounded by baseline symptom severity and do not accurately reflect symptom improvement.
Treatment trials for irritable bowel syndrome (IBS) usually define a responder as a patient who reports satisfactory relief or adequate relief of symptoms at the end of the trial. However, these measures have not been adequately validated. ⋯ These data from a descriptive study suggest that satisfactory relief is confounded with initial IBS symptom severity and is poorly correlated with the amount of symptom improvement. Confirmation of these findings in a clinical trial is needed.

Endoscopic sedation in the United States: results from a nationwide survey.
The introduction of new sedative agents as well as a desire for improved patient satisfaction and greater efficiency has changed the practice of endoscopic sedation. This survey was designed to provide national and regional data on endoscopic sedation and monitoring practices within the United States. ⋯ During the past 15 yr, the volume of procedures performed by endoscopists in the United States has increased two- to fourfold. Propofol is currently being used for sedation in approximately one quarter of all endoscopies in the United States. The findings from this survey may help in the formulation of updated policies and practice guidelines pertaining to endoscopic sedation.
