A Quasi-Experimental Evaluation of an Education Program for the Use of Electrical Stimulation Therapy to Heal Pressure Injuries.

Electrical stimulation (E-Stim) involves applying low levels of electrical current. Despite high-level recommendations for E-stim use in many pressure injury (PrI) best practice treatment guidelines, clinicians seldom use E-Stim. PURPOSE: This quasi-experimental design study aimed to determine whether an educational program could improve health care providers' knowledge and attitudes regarding the use of E-Stim for treating PrIs in community-dwelling individuals with spinal cord injury living in 1 region of Ontario, Canada. METHODS: An educational intervention based on a university-level continuing education program was developed as part of a multifaceted knowledge mobilization project. Health care providers (eg, nurses, physicians, and allied health professionals) from multiple agencies were invited to participate. The instructional series included 8 online modules on background theory and knowledge and a hands-on workshop that familiarized participants with the equipment necessary to deliver E-Stim. Knowledge (percentage of correct answers using a knowledge test developed by the research team) and attitudes (assessed using the E-Stim Attitude Survey in which items were scored using a 5-point Likert scale (where 0 indicated a negative attitude and 5 a positive attitude) were evaluated 3 times (pre-education, post-online, and post-workshop). Data were aggregated into unit-weighted averaged composites of 3 attitude subscales (resources, evidence-based practice, and education), which were compared before and after educational sessions using a linear mixed effect model. RESULTS: Among the 83 participants, a significant increase in knowledge scores was noted from pre-education (55.9%) to post-online (78.4%) and post-workshop (78.0%) (X² [2] = 89.34; P <.001). A significant increase in attitude scores was noted across time points (resources: X² [2] = 27.32, P <.0001; evidence-based practice: X² [2] = 38.93, P <.0001; and education: X² [2] = 92.88, P <.0001). For the evidence-based practice subscale, attitude increased significantly post-online (t[127] = 6.03, P <.0001). For the resources subscale, a significant increase was detected after post-workshop (t[113] = 5.23, P <.001]. CONCLUSIONS: Online education increased health care providers' knowledge about E-Stim; however, hands-on workshops were required to change certain attitudes about the use of E-Stim for wound healing. Further research is required to evaluate 1) whether a change in knowledge and attitude scores translates to a practice change for health care providers and 2) the potential importance of ongoing coaching and mentorship for a sustainable change in the clinical setting.

A Systematic Review and Meta-analysis of Exercise Intervention for the Treatment of Calf Muscle Pump Impairment in Individuals with Chronic Venous Insufficiency.

Exercise intervention for individuals with chronic venous insufficiency (CVI) and venous leg ulcers (VLUs) is recommended to improve function of the calf muscle pump (CMP). A systematic review with meta-analysis was conducted to measure the effects of exercise (including function of the CMP, ankle strength, range of motion [ROM], and healing rates) for VLUs. Four (4) databases (Cumulative Index to Nursing and Applied Health Literature, 1981; MEDLINE, 1964; Scopus, 1966; and EMBASE, 1947) were searched for relevant articles from the date of index inception to January 2016. All study types that evaluated the effect of exercise on the function of the CMP in patients with CVI were included; narrative and systematic studies were excluded. All data were extracted by 1 reviewer onto a predetermined form and verified by a second reviewer. Data extracted included number of patients, primary diagnosis, patient demographics, study location, wound characteristics, inclusion/exclusion criteria, exercise group details, control group details, co-interventions, primary outcome measures, secondary outcome measures, wound healing measures, blinding, intention to treat, and study design. A total of 1325 articles was screened; 14 met the inclusion criteria (total study participants = 519). CMP hemodynamics were assessed using air plethysmography measurement results from the included studies. A meta-analysis of 8 articles was distilled to 3 with relevant data (83 participants) that found a significant increase on CMP ejection fraction in favor of the exercise group (Hedge's g = 0.83; 95% CI 0.35-1.30, P <.001) compared to control. CMP residual venous fraction also favored the exercise group (Hedge's g = 0.42; 95% CI -0.03-0.862, P = .066). Ankle ROM was higher in the exercise group (116 participants; Hedge's g = 0.62; 95% CI -0.15-1.39, P = .116); however, these differences were not significantly different from controls. Exercise directed at improving calf muscle strength and ankle ROM for individuals with or at risk for VLUs improves CMP hemodynamics and function. Additional research using larger sample sizes to confirm the role of exercise in healing VLUs is warranted.

A prospective, multicenter study to validate use of the PUSH in patients with diabetic, venous, and pressure ulcers.

Monitoring wound progress is essential for evaluating and documenting treatment outcomes. The Pressure Ulcer Scale for Healing (PUSH) was developed to track pressure ulcer (PU) progress but information about its utility for other types of chronic wounds is limited. A 10-month, descriptive, multicenter study was conducted to examine the responsiveness and concurrent validity of the PUSH when used to monitor wound changes in diabetic foot (DFU), venous leg (VLU), and PU. Using a convenience sample of participants (n = 98, mean age 60 [range 20 to 89] years, the majority [85%] male), PUSH score and acetate wound surface area tracings were obtained at baseline and approximately 4 weeks later from 47 Stage II to Stage IV PU, 23 VLU, and 28 patients with a DFU. After an average of 32 days, wound surface area, total PUSH scores, and individual PUSH component scores decreased significantly between baseline and follow-up (P = 0.000). The mean PUSH score change was significantly different between healing and nonhealing wounds (P = 0.000). A strong relationship (r = .66) was found between total PUSH score and surface area. Results suggest the PUSH tool is a valid, responsive, evaluative tool to monitor and document wound progress of PU, VLU, and DFU. Additional studies to assess use of this tool for DFU and to ascertain the predictive validity of the PUSH tool are warranted.
