Updating Wound Care Algorithms: A Systematic, Focused Review

Abstract

Purpose: The purpose of this project was to update the underlying evidence base for basic wound care in the Solutions Wound Care Algorithms and revise this resource as needed.

Methods: The 14 major algorithm goals, guidelines, and outcomes of patient care and 34 detailed qualifying assessment and management statements/steps were reconstructed to encompass 21 qualifying statements/steps and aligned with their most recent (2013) levels of evidence. Next, a systematic, focused review of the literature was conducted to update the evidence levels using the Strength of Recommendation Taxonomy.

Search strategy: An English language search of CINAHL, Medline, Cochrane Library, and Joanna Briggs Institute (JBI) electronic databases was conducted for the years 2015-2023. For each wound type, the following search terms were used: meta-analysis, systematic review, randomized controlled trial, clinical practice guideline, clinical trial, and wound care/healing and dressings. Publications not focused on the patient population or qualifying statements were excluded.

Findings: The search retrieved 59 elements that met the predetermined criteria for analysis and leveling. All qualifying statements and steps remain evidence-based. Higher quality evidence became available for nutritional status assessment, exercise to reduce risk factors for various types of lower extremity ulcers, using tap water to cleanse wounds; that delayed wound healing may be a sign of infection, and that silver-containing dressings are effective when used appropriately. No basic patient and wound care steps have the highest level of evidence (level 1) and strength of recommendation (A).

Conclusion: Compared to previous updates, we found fewer clinical trials indicating a need for research to improve evidence levels for various steps of basic wound assessment and care processes.
