I found the module, with its slideshow-like presentation, to be extremely user-friendly. It was filled with thorough definitions and clear descriptions (textual and visual) of the differences between the each stage (I, II, III, and IV). There was the usual diagram of typical locations where one might find pressure ulcers, but also a mention of unusual sites.
There was also a lot of information that was new to me. For instance, I was curious what unstageable ulcers were. The module explains that the wound can simply be covered by too much slough to clearly determine the depth of the ulcer, but that the slough should not be manually removed for the purpose of staging. Also, I was unaware of the close relationship between DTIs and pressure ulcers. The module thoroughly delineates the differences between Deep Tissue Injury (DTI) and Stage I pressure ulcers, which have similar etiologies but differing symptoms. I learned that healing pressure ulcers cannot be re-staged. Once it is a Stage IV, it is always a Stage IV, even if it is barely visible. The module makes a good point that ulcers in some areas (bridge of nose, ear, occiput, and malleolus) may be shallow, but can still be Stage III or IV.
At the end of the module, there is a 12-question test in which the user must, through photographs and descriptions, identify the stage of the ulcer, or whether it is unstageable or a DTI. The user has the option of printing the results to provided verification of completion to ones employer.
All in all, I found the module to be a very good review of a working knowledge of pressure ulcers. There was no information on how to properly care for a patient with pressure ulcers (wound care, dressing changes, positioning, etc.). It simply provided an introduction to identifying and staging ulcers. As such, I think this module would be a useful training tool for all Nurses and Assistive Personnel, as a means of preventing the development of pressure ulcers or the worsening of existing ones. Id also recommend this module to nursing students reviewing for comprehensive exams.
