Sacred cow gone to pasture: a systematic evaluation and integration of evidence-based practice.

BACKGROUND

Sacred cows (SC) are old habits in practice, considered routine and above dispute, regardless of evidence to the contrary.

PURPOSE: This is the first known report that aims to conduct a systematic evaluation of practices that have been described in the literature as SC and strategies for planned implementation of evidence-based practices (EBP).

METHODS

A large, complex, academic medical center department of nursing compared SC to EBP. Nurses systematically reviewed and rated the degree to which current practices adhered to best-evidence versus SC. This initiative, "Sacred Cow: Gone to Pasture," was developed, structured, and implemented according to the Iowa Model of Evidence-Based Practice to Promote Quality Care, as well as Everett Rogers' Diffusions of Innovations Theory. Implementation of EBP followed a phase plan using the Implementation Strategies for Evidence-Based Practice to help to support adoption and integration.

RESULTS

Review of organization-specific policies and procedures and reports of actual practices revealed that SC persist, even in a center internationally recognized as a leader in EBP. The SC initiative caught the attention of busy clinicians, and raised awareness of SC and the importance of adherence to EBP. The SC initiative resulted in policy and practice changes and sparked new EBP and research, resulting in numerous improvements, including a significant decline in catheter-associated urinary tract infections and shifting from basins to commercially prepared cloths for patient bathing.

LINKING EVIDENCE TO ACTION: A strategic approach is crucial to eliminating SC and integrating EBP. This report calls nurses globally to action, to identify and abandon ineffective healthcare practices. Further research should compare and test the efficacy of implementation strategies, in particular how to sustain EBP in clinical settings.
