An evaluation of pre-post antimicrobial stewardship healthcare educational intervention studies utilizing the Kirkpatrick model: a scoping review.

Introduction: Antimicrobial stewardship (AMS) education plays a vital role in addressing antimicrobial resistance (AMR), yet its long-term impact on behavior and clinical outcomes remains underexplored. Educational interventions are often assessed through knowledge-based outcomes, with limited evaluation of sustained practice changes or patient-level results, and standardized higher-level outcome measures across diverse healthcare settings.

Aim: This scoping review aimed to map pre-post AMS healthcare educational interventions using the Kirkpatrick Model, evaluating their effectiveness across its four levels: reaction, learning, behavior, and results. The goal was to identify trends, highlight gaps, and provide insight into reported outcomes, delivery methods, and evaluation tools, supporting future research and strengthening the evidence base for AMS education.

Method: This review followed the Joanna Briggs Institute framework. A literature search of nine databases identified studies from 2010 to 2024. Eligible studies included pre-post AMS educational interventions targeting undergraduate students and healthcare professionals (HCPs) and reporting outcomes which were subsequently mapped by the reviewers to the Kirkpatrick Model. Data were categorized by target population, delivery format, and evaluation tools. Narrative synthesis was used to describe trends and relationships.

Results: Studies targeted HCPs such as physicians, pharmacists, nurses, and dental professionals, and undergraduate students in pharmacy, medicine, nursing, and dentistry. Sixty-three studies were included. Outcomes were distributed across Level 1 (Reaction) (n = 46, 24%), Level 2 (Learning) (n = 51, 27%), Level 3 (Behavior) (n = 50, 26%), and Level 4 (Results) (n = 45, 23%). While n = 24 (38%) assessed all four levels, another n = 24 (38%) reported mixed or partial levels. Face-to-face or online-only formats achieved Levels 1 and 2. Whereas blended or workplace-integrated interventions more often demonstrated behavior change and clinical outcomes (Levels 3 and 4). Longitudinal follow-up and mixed evaluation tools (e.g., surveys, chart reviews, interviews) supported higher-level impacts. Pharmacy-led, interdisciplinary, and contextually tailored interventions mapped to all levels.

Conclusion: AMS education often leads to short-term learning gains, but fewer interventions achieve sustained behavior change or measurable clinical outcomes. Blended and practice-integrated formats, paired with long-term evaluation, are key to realizing the full potential of AMS education. Embedding such approaches in undergraduate and professional programs can better prepare the future HCPs to address AMR effectively.
