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

UNLABELLED

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.
