Complex interventions for preventing diabetic foot ulceration.

Area of Science:

• Podiatry
• Diabetology
• Public Health

Background:

• Diabetic foot ulcers pose a significant risk for amputation and incur substantial economic costs.
• Single preventive strategies have proven insufficient in reducing the incidence of diabetic foot ulcers.
• Complex interventions, integrating multiple prevention strategies, are increasingly used in clinical practice.

Purpose of the Study:

• To evaluate the effectiveness of complex interventions in preventing diabetic foot ulcers.
• To compare complex interventions against single interventions, usual care, or alternative complex interventions.
• To define complex interventions as integrated care combining multiple strategies across patient, provider, and healthcare structure levels.

Main Methods:

• Searched multiple databases including Cochrane, MEDLINE, EMBASE, and CINAHL up to May 2015.
• Included prospective randomized controlled trials (RCTs) comparing combinations of preventive strategies (excluding solely patient education) against controls.
• Two independent reviewers selected studies, extracted data, and assessed risk of bias.

Main Results:

• Six RCTs met inclusion criteria, exhibiting significant heterogeneity in settings, interventions, and outcomes.
• Education-centered complex interventions showed minimal benefit compared to usual care or written instructions.
• More comprehensive complex interventions demonstrated significant reductions in lower extremity amputations and foot ulcers in some studies, though all RCTs had 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 patient population.
• Further rigorous research is required to establish the efficacy of these multifaceted approaches.
