Self-Management Improves Outcomes in Persons With Limb Loss
ABSTRACT To test the acceptance and effectiveness of a community-based self-management (SM) intervention designed to improve outcomes after limb loss. A priori hypothesis was that an SM intervention will be more effective than standard support group activities in improving outcomes.
Randomized controlled trial.
Intervention (N=287) and control participants (N=235) with major limb loss.
Nine, 90-minute SM group sessions delivered by trained volunteer leaders. Retention rates at immediate postintervention and 6-month follow-up were 97% and 91% for the SM group.
Primary outcomes were depression, positive mood, and self-efficacy. Secondary outcomes were improved functional status and quality of life.
By using intent-to-treat analyses, the odds for being depressed are significantly lower for those in SM group, 50% less likely at treatment completion (95% confidence interval [CI]=0.3-0.9) and 40% less likely at the 6-month follow-up (95% CI=.03-1.1). Treatment completers have a 70% reduction in likelihood of being depressed at posttreatment (P<.01) and this persists at six months (P<.05). For those in the SM group, functional limitations were significantly lower at 6 months (P<.05), and general self-efficacy was significantly higher at immediate posttreatment (P<.05) and at 6 months (P<.05). Treatment completers have generally significantly larger effect sizes at all follow-up points. Pain intensity, self-efficacy for pain control, and quality of life were not significantly different between the groups. Subgroup analyses indicated the impact of the intervention was greater for participants who were less than 3 years postamputation, participants who were less than 65 years of age, or participants who showed at least 1 secondary condition at baseline.
The study provides evidence that SM interventions can improve the outcomes of persons with limb loss beyond benefits offered by support groups.

ABSTRACT: The Trauma Survivors Network is a multimodal program for trauma patients and their families. Despite training representatives of 30 trauma centers, only 3 have fully implemented the program. The purpose of this study was to identify barriers to program implementation among trainees through in-depth phone interviews and an electronic survey. Although interviewees were positive about the Trauma Survivors Network concept, they identified numerous barriers to implementation. Trainee confidence in their ability to implement program components was predictive of their success. We recommend that future trainings include program advocacy, implementation skills, and an assessment of trainees' roles in the hospital.Journal of trauma nursing: the official journal of the Society of Trauma Nurses 01/2013; 20(2):89-99.

ABSTRACT: Home-based patient-delivered mirror therapy is a promising approach in the treatment of phantom limb pain. Previous studies and case reports of mirror therapy have used a therapist-guided, structured protocol of exercises. No case report has described treatment for either upper or lower limb phantom pain by using home-based patient-delivered mirror therapy. The success of this case demonstrates that home-based patient-delivered mirror therapy may be an efficacious, low-cost treatment option that would eliminate many traditional barriers to care.American journal of physical medicine & rehabilitation / Association of Academic Physiatrists 02/2009; 88(1):78-81.
