Lay Caregivers Education in Multicomponent Compression Bandaging in Obese Patients with Lower Limb Edema: A Case-Control Pilot Study.

Background: A report on the usefulness of the instruction of lay carers in multilayer short-stretch compression bandaging within the initial intensive phase physical treatment of mixed-etiology chronic lower limb edema. Methods and Results: In a group of adult obese patients (including 24 females) with venous insufficiency and chronic bilateral lower limb edema, and without a history of physical therapy, 20 (ambulatory managed) were bandaged once daily (four layers, short stretch with cotton tube, and foam padding underneath) for 3 weeks (Monday-Friday) by skilled physiotherapists, and in 20 cases (education group, EG), the patients' lay carers were educated by these physiotherapists according to the same regime during one session. The outcome measures included limb volume (the method of circumference measurement with a tape at 4 cm intervals) after 1, 3, and 6 months, the time to reach the maintenance phase, the frequency of complementary bandaging during this phase, and the sense of self-efficacy (General Self-Efficacy scale, GSEs). No significant differences were noted between the two groups in the baseline measurements of age, body mass, and limb volume. The carers were able to apply compression bandages in all cases during the observation period. The time to reach the maintenance phase was longer in EG (6 vs. 1 weeks; p < 0.001). A similar median reduction in edema volume was observed at the end of the bandaging period, which continued for 3 and 6 months. It was only in EG that further improvement between 1 and 3 months was observed (p = 0.008). All participants represented an equally high optimistic sense of personal competence (GSEs). Conclusions: The instruction of lay carers in bandaging may provide a simple clinically effective solution for lower limb edema management, thus lowering its costs.
