Measuring outcomes in psychiatry: an inpatient model.

BACKGROUND: This article describes a system for measuring outcomes recently implemented in the department of psychiatry of Baptist Memorial Hospital, a 78-bed inpatient and day treatment unit that represents one service line of a large, urban teaching hospital in Memphis. In June 1993 Baptist Hospital began a 15-month pilot test of PsychSentinel, a measurement tool developed by researchers in the Department of Community Medicine at the University of Connecticut. The hospital identified the following four primary goals for this pilot project: provide data for internal hospital program evaluation, provide data for external marketing in a managed care environment, satisfy requirements of the Joint Commission on Accreditation of Health Care Organizations, and generate studies that add to the literature in psychiatry and psychology. DESCRIPTION OF MEASURE: PsychSentinel is based on the standardized diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV). The outcome measure assesses the change in the number of symptoms of psychopathology that occurs between admission and discharge from the hospital. Included in the nonproprietary system are risk adjustment factors, as well as access to a national reference database for comparative analysis purposes. Data collection can be done by trained ancillary staff members, with as much or as little direct physician involvement as desired. The system has proven to be both time effective and cost effective, and it provides important outcome information both at the program level and at the clinician level. RESULTS: After the pilot test, the staff at Baptist Memorial Hospital determined that the system met all initial objectives identified and recently adopted the system as an ongoing measure of quality patient care in the department of psychiatry.

Travel at low energetic cost by swimming and wave-riding bottlenose dolphins.

Over the past 50 years there has been much speculation about the energetic cost of swimming and wave-riding by dolphins. When aligned properly in front of the bow of moving ships in the stern wake of small boats, on wind waves, and even in the wake of larger cetaceans, the animals appear to move effortlessly through the water without the benefit of propulsive strokes by the flukes. Theoretically, body streamlining as well as other anatomical and behavioural adaptations contribute to low transport costs in these animals. The economy of movement permitted by wave-riding has been perceived as an energetic advantage for the swimming dolphin, but has been hard to prove in the absence of physiological data for exercising cetaceans. Here we determine the aerobic and anaerobic costs of swimming and wave-riding in bottlenose dolphins and find that the minimum cost of transport for swimming dolphins is 1.29 +/- 0.05 J kg-1 m-1 at a cruising speed of 2.1 m s-1. Aerobic costs are nearly twice as high for swimming seals and sea lions, and 8-12 times higher for human swimmers. Wave-riding by dolphins provides additional benefits in terms of speed. The results indicate that behavioural, physiological and morphological factors make swimming an economical form of high-speed travel for dolphins.
