Systematic Reviews and Meta-Analyses - Literature-based Recommendations for Evaluating Strengths, Weaknesses, and Clinical Value.

Abstract

Good quality systematic reviews (SRs) summarizing best available evidence can help inform clinical decisions, improv- ing patient and wound outcomes. Weak SRs can misinform readers, undermining care decisions and evidence-based practice. To examine the strengths and weaknesses of SRs and meta-analyses and the role of SRs in contemporary evidence-based wound care practice, and using the search terms systematic review, meta-analysis, and evidence-based practice, the authors searched Medline and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) for important terminology and recommendations to help clinicians evaluate SRs with meta-analysis. Reputable websites, recent textbooks, and synthesized available literature also were reviewed to describe and summarize SR strengths and weaknesses. After developing a checklist for critically evaluating SR objectives, inclusion/exclusion criteria, study quality, data extraction and synthesis methods, meta-analysis homogeneity, accuracy of results, interpretation, and consistency between significant findings and abstract or conclusions, the checklist was applied to topical wound care SRs identified in Cochrane and MEDLINE searches. Best available evidence included in the SRs from 169 randomized controlled trials on 11,571 patients supporting topical intervention healing effects on burns, surgical sites, and diabetic, venous, or pressure ulcers was summarized and showed SRs and clinical trials can demonstrate different outcomes because the information/data are compiled differently. The results illustrate how evidence insufficient to support firm conclusions may still meet immediate needs to guide carefully considered clinical wound and patient care decisions while encouraging better future science.
