Wound care products: how to choose.

Working in PPS means that agencies and clinicians must determine which wound care regimen will reach the intended patient goal in the most cost-effective way in terms of supply and visit cost. This article outlines the specific rationale clinicians can use when assessing wounds and choosing the dressing(s) that are appropriate to meet patient and agency goals. Using the performance-based model approach, clinicians learn how to choose dressings based on product price versus treatment costs.

Hanging wet-to-dry dressings out to dry.

Wet-to-dry dressings have been standard procedure for home care wound care patients although research indicates gauze dressings are not an optimal wound care modality for the patient, the clinician, or the healthcare system. Gauze dressings do not effectively support optimal healing and are more labor intensive to use than advanced dressings such as films, foams, hydrocolloids, and hydrogels. This article provides clinicians with the rationale and evidence needed to collaborate with physicians in choosing the most cost-effective wound care products to achieve positive patient outcomes.

Battling bacteria in wound care.

A critical aspect of effective and cost-efficient wound management is infection prevention and actions taken to minimize bacterial levels in the wound. This article describes effective wound cleansing and debridement, appropriate use of advanced dressings, procedures for dressing changes, and the appropriate use and understanding of topical antimicrobial agents.

Dressings and ajunctive therapies: AHCPR guidelines revisited.

The Agency for Health Care Policy and Research Pressure Ulcer Treatment Guidelines released in 1994 offered 11 recommendations relating to the use of dressings and adjunctive therapies. These recommendations were based on evidence gleaned from the medical literature from 1966 to mid-1993 as well as the accumulated expertise of a multidisciplinary advisory panel. As the recommendations are now 5 years old, a review of the literature published since 1993 was undertaken in order to determine additional evidence for their continued validity or disapproval. The review focused on evidence at the level of controlled clinical trials of dressings and adjunctive therapies in the treatment of pressure ulcers.

What is needed to monitor healing in the outpatient clinic setting?

To monitor healing in the outpatient setting, clinicians need: easily usable tools to collect data, whether a checklist or software program real-time analysis (or at least timely analysis) of the data relative to a treatment protocol a method of analysis that allows manipulation of the data for multiple purposes communication of the analysis; future actions should be based on this analysis. The result will be a dynamic, cyclical monitoring system, most meaningful when it is not retrospective and static, but fluid so that adjustments can be made as needed.

Wound healing microbiology.

The relationship between wound healing and cutaneous microbiology is a complex one mediated by the type of wound, its treatment, and the defense mounted by the injured individual. Acute wounds harbor microflora similar to that of noninjured skin. "Dirty" traumatic wounds or chronic wounds with devitalized tissue offer more opportunity for microflora colonization, with the potential for bacterial adherence to the host cells and ultimate invasion into viable tissue or infection. The alterations of these wound environments can be brought on by topical treatments. Occlusive dressings with various moisture vapor transmission rates can provide a wound environment suitable for microflora proliferation. In spite of this increase in numbers of organisms, most wounds do not become infected, as shown by a survey of published trials. Infection requires the proper pathogenic microorganism, its attachment, and subsequent multiplication. To cause an infection, an organism must invade viable tissue and evade the host defense response. The many occlusive dressing types available offer an opportunity to select a wound therapy tailored for the microenvironment most suitable for healing. Wounds can be protected from exogenous microfloral contamination with dressings. Some dressing types, such as hydrocolloid dressings with no moisture vapor transmission, should not be used on chronic wounds suspected of harboring anaerobic organisms. Other typical treatments, such as antiseptics, can injure tissue and make infection more probable, providing devitalized tissue for bacterial adhesion. Povidone-iodine solution has been shown not be efficacious, whereas povidone-iodine cream effectively limits bacteria and infection.(ABSTRACT TRUNCATED AT 250 WORDS)

Electrical stimulation and ultrasound in wound healing.

The events that lead to tissue repair are very complex. Because our understanding of these processes is increasing in scope, the use of nontraditional treatment therapies should be considered. Evidence is reported in the literature that both electrical stimulation and ultrasound therapies may be beneficial in certain circumstances to heal various wound types. Owing to clinicians' unfamiliarity with the current research and general understanding of such therapies, many patients receive only traditional treatment and remain unexposed to the potential benefits of the nontraditional. With continued research to better define optimal treatment parameters, improved wound healing will result.
