Risk factors associated with healing chronic diabetic foot ulcers: the importance of hyperglycemia.
Diabetic foot ulcer management presents a significant challenge for wound care clinicians; numerous approaches to encourage healing in these difficult wounds have been explored. To determine risk factors related to diabetic foot ulcer time to healing and closure, a secondary analysis of data from a prospective randomized study involving 245 patients treated with a bioengineered human dermal substitute (n = 130) or control treatment (n = 115) was conducted. Analyzed variables included age, race, gender, ulcer duration, initial ulcer size, initial hemoglobin (HgbA1c), average HgbA1c, change in HgbA1c, diabetes type, average hours of weight-bearing, study ulcer infection, history of smoking or alcohol use, and laboratory values. ⋯ Female gender, small ulcer size, and the absence of infection were found to have a positive effect on healing all diabetic foot ulcers; improved glucose control had a significant effect on healing wounds managed with the dermal substitute only. This is the first diabetic foot ulcer study to find a relationship between hyperglycemia and wound healing. Further research into factors that improve healing of wounds, including diabetic foot ulcers, is warranted.

Comparative StudyPressure ulcers in German nursing homes and acute care hospitals: prevalence, frequency, and ulcer characteristics.
In German healthcare facilities, research-based knowledge of pressure ulcers and their relation to patient characteristics is limited. To provide information for national and international comparison on pressure ulcers and related issues, two cross-sectional surveys were conducted among 21,574 German hospital patients and nursing home residents (147 institutions total) in 2002 and 2003. Prevalence and frequency rates of pressure ulcers in people at risk (Braden score of

Implementing a pressure ulcer prevention program and enhancing the role of the CWOCN: impact on outcomes.
Hospitals in the US are increasingly concerned with the rising number of hospital-acquired pressure ulcers. To reduce its 2002-2003 average hospital-acquired pressure ulcer prevalence rate of 9.2%, a regional medical center in southeastern US initiated a process improvement and education program. Quarterly pressure ulcer prevalence studies were conducted and the Medical Intensive Care Unit was found to have the highest number of hospital-acquired pressure ulcers among the five units participating in the study. ⋯ Implementing these changes resulted in a decrease in the quarterly hospital-acquired pressure ulcer prevalence in participating units, including the Medical Intensive Care Unit where rates dropped from a high of 29% to near 0%. Clinicians now approach pressure ulcers as preventable rather than inevitable and view Certified Wound Ostomy Continence Nurses as resources and clinical experts for prevention and treatment. Overall quality of care and financial resource utilization also have substantially improved.

Comparative StudySilver deposition and tissue staining associated with wound dressings containing silver.
Argyria is the general term used to denote a clinical condition in which excessive administration and deposition of silver causes a permanent irreversible gray-blue discoloration of the skin or mucous membranes. The amount of discoloration usually depends on the route of silver delivery (ie, oral or topical administration) along with the body's ability to absorb and excrete the administered silver compound. Argyria is accepted as a rare dermatosis but once silver particles are deposited, they remain immobile and may accumulate during the aging process. ⋯ When the dressings were hydrated with water, a significantly higher amount of silver was released from the nanocrystalline dressing compared to the Hydrofiber dressing (P <0.005), which resulted in approximately 30 times more silver deposition. In contrast, when saline was used as the hydration medium, the release rates were low for both dressings and not significantly different (silver deposition was minimal). Controlling the amount of silver released from silver-containing dressings should help reduce excessive deposition of silver into wound tissue and minimize skin staining.

Multicenter Study Clinical TrialEffect of ultraviolet light C on bacterial colonization in chronic wounds.
Ultraviolet light C (light wavelength 200 nm to 290 nm) has been shown to kill cultures of antibiotic resistant strains of bacteria such as methicillin-resistant Staphylococcus aureus. To evaluate the ability of ultraviolet light C to reduce the amount and type of bacteria present in chronically infected ulcers, as well as to establish the test-retest reliability of the semi-quantitative swab technique, a prospective, one-group, pre-post treatment study was conducted among patients receiving treatment in several in- and outpatient facilities and nursing homes. Individuals with chronic ulcers exhibiting at least two signs of infection and critically colonized with bacteria (n = 22) received a single 180-second treatment using an ultraviolet light C lamp (wavelength = 254 nm) placed 1 inch from the wound bed. ⋯ The greatest reduction in semi-quantitative swab scores following ultraviolet light C treatment were observed for wounds colonized with the bacteria Pseudomonas aeruginosa and wounds colonized with only one species of bacteria. Significant (P <0.05) reductions in the relative amount of bacteria also were observed in 12 ulcers in which methicillin-resistant Staphylococcus aureus was present. These results confirm previous laboratory studies and demonstrate that ultraviolet light C can kill bacteria such as Pseudomonas aeruginosa, Staphylococcus aureus, and methicillin-resistant Staphylococcus aureus present in superficial layers of chronic wounds.
