Complex interventions for preventing diabetic foot ulceration.

Area of Science:

• Podiatry
• Diabetology
• Public Health

Background:

• Diabetic foot ulcers are a significant cause of lower limb amputations and economic burden.
• Single preventive strategies have proven insufficient in reducing ulcer incidence.
• Complex interventions integrate multiple strategies targeting patients, healthcare providers, and healthcare structures.

Purpose of the Study:

• To evaluate the effectiveness of complex interventions versus single interventions or usual care for preventing diabetic foot ulcers.
• To assess integrated care approaches combining multiple prevention strategies.

Main Methods:

• Searched multiple databases including Cochrane CENTRAL, MEDLINE, EMBASE, and CINAHL for relevant studies.
• Included prospective randomized controlled trials (RCTs) comparing complex interventions with single interventions or usual care.
• Two independent reviewers selected studies, extracted data, and assessed risk of bias.

Main Results:

• Only five RCTs met inclusion criteria, exhibiting substantial heterogeneity in study design and interventions.
• Education-centered complex interventions showed little benefit compared to usual care or written instructions.
• More intensive complex interventions demonstrated potential, with one study reporting improved self-care and another a significant, cost-effective reduction in amputations (RR 0.30).
• All included RCTs were assessed as having a high risk of bias.

Conclusions:

• High-quality evidence evaluating complex interventions for diabetic foot ulcer prevention is lacking.
• Insufficient evidence currently supports the benefit of complex interventions in this area.
• Further rigorous research is required to establish the efficacy of these integrated approaches.
