The AAWC conceptual framework of quality systems for wound care.
When the Association for Advanced Wound Care Quality of Care Task Force members determined there was no unanimously accepted definition of quality as it relates to wound care, they: 1) identified relevant components of quality wound care, and 2) created a framework of quality wound care indicators to enable the creation or assessment of wound care delivery systems. The framework is an innovative conceptual model that serves as a basis for the Association strategies to facilitate high quality wound care for patients/clients across the continuum of care and recognizes the role of the supporting systems necessary to provide wound care services. It uses the Institute of Medicine's Crossing the Quality Chasm: A New Health System for the 21st Century to define quality systems for wound care and includes safety and effectiveness coupled with the delivery of timely, efficient, equitable, collaborative, patient-centered care. This framework can be utilized during clinical, managerial, or regulatory review of wound care service delivery.
Impact of antimicrobial gauze on bacterial colonies in wounds that require packing.
Heavy microbial contamination has been associated with delayed wound healing and infection in both acute and chronic wounds. A prospective, randomized, 5-week controlled, open label, multicenter study was conducted to determine whether using antimicrobial gauze containing polyhexamethylene biguanide in wounds that require packing will result in a greater reduction of bacterial colony counts than using a gauze without polyhexamethylene biguanide (the control). Twenty-one subjects were randomized to the treatment or control dressing. Wounds were evenly distributed with respect to etiology and both study groups had a median baseline wound size of 7 cm2. At baseline, 15 microbial isolates were recovered and counted in treatment group wounds and 12 were recovered in the controls. At Week 1, six isolates were recovered from subjects in the polyhexamethylene biguanide antimicrobial gauze treatment group while 10 were recovered in the control. Change in polymicrobial bioburden was most prominent during the first few weeks of the study in the polyhexamethylene biguanide group. Polymicrobial counts in the treatment group remained reduced for the following three study weeks, returning to baseline at Week 4. In the control group, the number of polymicrobial cultures rose to 60% above baseline at Week 4. Two wounds of subjects randomized to the polyhexamethylene biguanide antimicrobial gauze healed; one wound in the control group healed. Polyhexamethylene biguanide antimicrobial gauze dressing could be an important adjunct to control the polymicrobial bioburden of delayed closure surgical wounds, pressure ulcers, and diabetic foot ulcers. Additional studies seem warranted.
A new option in the treatment of skin tears for the institutionalized resident: formulated 2-octylcyanoacrylate topical bandage.
Skin tears are a common phenomenon in elderly institutionalized adults (EIAs). Incidence ranges from 0.92 to 2.5 per person/year. Little supportive literature exists regarding optimal treatment with many regimens reported. A convenience sample of 20 patients with Payne-Martin Category II and III skin tears of less than 8 hours' duration were prospectively evaluated with the use of a formulated 2-octylcyanoacrylate topical bandage. Patients were followed weekly until the tear healed. Complete healing occurred with 1 application of 2-OTB in 90% (18/20) of study subjects; 5% (n = 1) reported transient mild pain (less than 15 seconds), and 90% (n = 19) reported no pain. There were no incidents of cellulitis or infection. Shower and bathing routines were not interrupted. Cost averaged less than $1 per application. Clinician time averaged 1.5 minutes per application. Clinicians reported high satisfaction because repeated dressing changes were eliminated.
