摘要:

This study used two full-size pressure-sensitive mats to evaluate five patient support surfaces. The mats, containing 1,536 and 2,340 pressure measurement sites, respectively, made it possible to quantify the entire interface pressure distribution of each support surface. Measurements for groups of 64 and 32 subjects were obtained in supine positions of 0° 30°, at maximal head elevations 15°-60°), and at lateral recumbency. Several statistical descriptors were calculated to characterize the interface pressure distributions. The support surfaces tested included: a powered-air overlay (ACUCAIR Continuous-Air-flow System), a low-airloss bed (FLEXICAIRMC3 Low-Airloss Therapy), a continuous lateral-rotation low-airloss bed (RESTCUE Dynamic Air Therapy®), an air-fluidized bed (CLINITROX II Air-Fluidized Therapy), and an integrated bed (prototype Advance 2000 Bed). An analysis of variance revealed that the interface pressure was significantly lower and weight-bearing area was significantly higher on the five surfaces, when compared to the standard hospital mattress.

摘要:

Despite ongoing efforts to improve the prediction, prevention, and treatment of pressure ulcers, clinicians continue to face an over whelming array of confusing, and some times conflicting, information about the technologies used to lower pressure. The purpose of this article is to explain the fundamental differences among units of pressure measurement and those pressures (capillary closing, tissue interface, internal cushion, and hydrostatic) that arc commonly described in research as well as sales literature. A clearer understanding of these parameters will help clinicians make informed evaluations of distinct technologies, set realistic expectations for different products, and achieve desired outcomes cost-effectively.

摘要:

Preventing Pressure Ulcers —A patient's guide was released by the Agency for Health Care Policy and Research (AHCPR) in May 1992. Using criteria suggested by Falvo (1985), Redman (1988), Ruzicki (1989), and others, the guide was critiqued to determine how it compared to existing criteria for evaluating written tools. The AHCPR guideline does not meet all the criteria: suggestions for improvement are provided.

摘要:

The validity of an instrument is another important issue for the clinician to consider when selecting a tool for use in data collection. Broadly defined, validity refers to the extent to which an instrument measures what it is supposed to be measuring. Although validity is a unitary concept, this article explores three common categories of validity: content, criterion-related, and construct validity.
