Wound Bed Preparation is a paradigm to optimize chronic wound treatment. This holistic approach examines the treatment of the cause and patient-centered concerns to determine if a wound is healable, a maintenance wound, or nonhealable (palliative). For healable wounds (with adequate blood supply and a cause that can be corrected), moisture balance is indicated along with active debridement and control of local infection or abnormal inflammation. In maintenance and nonhealable wounds, the emphasis changes to patient comfort, relieving pain, controlling odor, preventing infection by decreasing bacteria on the wound surface, conservative debridement of slough, and moisture management including exudate control. In this fourth revision, the authors have reformulated the model into 10 statements. This article will focus on the literature in the last 5 years or new interpretations of older literature. This process is designed to facilitate knowledge translation in the clinical setting and improve patient outcomes at a lower cost to the healthcare system. GENERAL PURPOSE To present the 2021 update of the Wound Bed Preparation paradigm. TARGET AUDIENCE This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES After participating in this educational activity, the participant will: 1. Apply wound assessment strategies. 2. Identify patient concerns about wound care. 3. Select management options for healable, nonhealable, and maintenance wounds.

GENERAL PURPOSE To present a cross-sectional cohort study conducted to assess the association between wound pH, local infection, and deep/surrounding infection. TARGET AUDIENCE This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES After participating in this educational activity, the participant should be better able to: 1. Synthesize the background information associated with the study assessing the association between wound pH, local infection, and deep/surrounding infection. 2. Summarize the results of the study presented here. BACKGROUND Wounds with a higher pH often demonstrate lower rates of healing. Local and deep/surrounding infection can be diagnosed with the validated NERDS and STONEES clinical signs, respectively. This study assessed the association between wound pH, local infection, and deep/surrounding infection. METHODS A 100-patient prospective cross-sectional cohort study was conducted with leg and foot wounds. Wound pH was measured using pH indicator strips. The wounds were assessed for clinical signs of local or deep/surrounding infection with the NERDS and STONEES criteria, respectively. Temperature measurements were documented with a handheld infrared skin thermometry device at the wound/periwound site, the equivalent site on the opposite side of the same leg/foot, and the wound mirror image site on the opposite leg/foot. RESULTS There was no significant difference in the mean wound bed pH in patients with superficial critical colonization and those without (P = .837). The wound and periwound maximum temperature measurements were compared with an equivalent temperature on the mirror image on the opposite leg. There was a statistically significant difference in the mean temperature (ΔT) value between patients with deep/surrounding wound infection and three or more positive STONEES criteria (P = .002). CONCLUSIONS Nontouch infrared thermometry comparing maximum mirror image wound temperatures versus the opposite extremities when combined with two or more other STONEES criteria is a significant indicator of deep and surrounding infection. Surface wound bed pH indicator strip measurements do not correlate with local wound infection using the NERDS criteria.

Foot health is important to overall patient health. Early diagnosis and treatment of diabetes, neuropathy, fungal foot infections, foot deformity, and vascular disease/lower leg edema can improve patient quality of life. One way to achieve this is effective screening. To this end, researchers piloted a validated 10-item screening tool to assess foot health on 120 patients; 74.17% had at least one positive abnormality, demonstrating the critical importance of these early findings. Only 25.83% of individuals had completely low-risk feet. This easy-to-use tool can assist healthcare professionals in the recognition and treatment of common foot problems. The article also outlines the early signs of disease by screening item and provides a guide to treatment to enable effective prevention and quality care. GENERAL PURPOSE To provide information on a 60-second General Foot Screen to assist in the prevention and/or identification and management of common foot problems. TARGET AUDIENCE This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES After participating in this educational activity, the participant should be better able to: 1. Use the 60-second General Foot Screen to assist healthcare professionals in the recognition of common foot problems. 2. Identify risk factors, causes, and treatment of selected foot problems.
