What's new in lower-extremity arterial disease? WOCN's 2008 clinical practice guideline

Smoking, chronic wound healing, and implications for evidence-based practice

Chronic wounds are rising in prevalence and creating significant socioeconomic burdens for patients and healthcare systems worldwide. Therefore, it is now more important than ever that clinicians follow evidence-based guidelines for wound care when developing personalized treatment plans for their patients with chronic wounds. Evidence-based guidelines for treating venous leg ulcers, diabetic foot ulcers, and pressure ulcers, the 3 main categories of chronic wounds, focus primarily on biologic therapies. However, there are also evidence-based guidelines for treating behavioral risks to poor healing, such as smoking, which should be incorporated into treatment plans when appropriate. The purpose of this article was to review the mechanisms through which smoking adversely impacts the wound healing process, and propose strategies for incorporating evidence-based guidelines for treating tobacco dependence into treatment plans for patients with chronic wounds who smoke.

The effect of a nurse-directed intervention to reduce pain and improve behavioral and physical outcomes in patients with critically colonized/infected chronic leg ulcers

PURPOSE

We compared a WOC nurse-directed, patient-centered intervention called MECALF (motivational enhancement and conditioning activity for leg function) compared to conditioning activities for lower leg function (CALF) alone. Outcomes were study feasibility, pain, motivation, self-efficacy, physical activity, leg strength, and range of motion.

DESIGN

Comparative study.

SUBJECTS AND SETTING

The sample was drawn from 2 wound centers in the Southeastern United States. Twenty-one patients (n = 12 MECALF site A and n = 9 CALF site B) with painful lower legs and critically colonized/infected wounds participated in the study.

METHODS

All patients received usual wound care per center protocol. The MECALF intervention was delivered by WOC nurses for 6 weeks at site A and a handout of CALF depicting the conditioning activities was provided by site staff (not WOC nurses) to patients at site B. We assessed study feasibility with postsurvey questionnaires given to WOC nurses (training usefulness, ease of use of ME with patients) and subjects (able to perform activities, use logs). Pre- and postintervention outcome data were collected by study staff using pain, motivation, and self-efficacy scales, functional measures of physical activity, and physical measures of strength and range of motion.

RESULTS

The study was found to be somewhat feasible by the WOC nurses and patients. WOC nurses had time management problems using MECALF during usual patient care. Patients reported that they were able to perform CALF. Overall pain was statistically significantly reduced (P = .046) in both groups of patients with painful critically colonized/infected leg ulcers measured at week 8, 2 weeks after the study period. The CALF group experienced a slightly greater reduction in pain intensity than did the MECALF group. No statistically significant differences between the groups were observed in behavioral outcomes for motivation (P = .641) and self-efficacy (P = .643), or for physical outcomes including overall ankle strength (P = .609) and ankle range of motion (P = .498). Functional and physical activity scores revealed no statistically significant differences in 3 measures, including Timed Up and Go test (P = .624), Timed Chair Standing Test (P = .686), or the Community Health Activities Model for Seniors (P = .803).

CONCLUSION

While somewhat feasible to implement in the wound care setting, no improvement in outcomes was observed with the addition of the WOC nurse-directed intervention. However, pain in the lower legs of patients with critically colonized/infected wounds in both groups improved after a 6-week behavioral/physical activity intervention. A larger trial is needed to further elucidate these findings.

Wound care basics for the pharmacist

Elderly skin is prone to wounds as a result of age-related changes and comorbidities such as diabetes and vascular disease. Wound healing is a complex process that can become compromised, leading to the development of chronic, nonhealing wounds in a frail elderly patient. Pharmacists and other practitioners who care for the elderly should be attuned to the wound-healing process and to the types of medications and wound care products available to aid healing.

Implementing a home-based exercise prescription for older patients with peripheral arterial disease and intermittent claudication: a quality improvement project

A Nurse Practitioner-led quality improvement project was implemented in a vascular surgical care clinic to facilitate home-based exercise for patients diagnosed with peripheral arterial disease (PAD) and intermittent claudication (IC). The primary goal of the project was to develop an information brochure about PAD and the benefits of exercise, as well as, a written prescription for home-based exercise program. These materials are used in the care of patients with PAD and IC to augment verbal recommendations normally provided by the healthcare provider. The project's secondary goal was to determine the impact of these materials on the frequency of home-based exercises among participating patients. After implementation of the project, 70% of the patients who received the exercise brochure and prescription reported exercising at least four times per week. Prior to implementing the project, 7 (47%) of the patients in the project reported exercising at least four times a week. Additionally, on the follow-up survey 16 (94%) patients reported participating in some form of exercise and only 1 (6%) patient did not report exercising. Before the project was implemented, 7 (41%) patients reported no regular exercise, and 10 (59%) patients reported exercise. After the project, there was a 35% increase in reported exercise among the patient population. This was a statistically significant finding in the project. This suggests the prescription could have caused the change in the patient reports.

Does incorporation of a clinical support template in the electronic medical record improve capture of wound care data in a cohort of veterans with diabetic foot ulcers?

PURPOSE

The purpose of this cohort study was to evaluate the effect of a 1-year intervention of an electronic medical record wound care template on the completeness of wound care documentation and medical coding compared to a similar time interval for the fiscal year preceding the intervention.

METHODS

From October 1, 2006, to September 30, 2007, a "good wound care" intervention was implemented at a rural Veterans Affairs facility to prevent amputations in veterans with diabetes and foot ulcers. The study protocol included a template with foot ulcer variables embedded in the electronic medical record to facilitate data collection, support clinical decision making, and improve ordering and medical coding.

RESULTS

The intervention group showed significant differences in complete documentation of good wound care compared to the historic control group (χ = 15.99, P < .001), complete documentation of coding for diagnoses and procedures (χ = 30.23, P < .001), and complete documentation of both good wound care and coding for diagnoses and procedures (χ = 14.96, P < .001).

CONCLUSIONS

An electronic wound care template improved documentation of evidence-based interventions and facilitated coding for wound complexity and procedures.
