Assessment of Antimicrobial Stewardship Program Effectiveness in Community Pharmacies

Thesis Abstract

The escalating global threat of antimicrobial resistance necessitates the implementation and assessment of effective antimicrobial stewardship programs (ASPs), particularly within community pharmacy settings where antibiotics are frequently dispensed. Despite widespread recognition of the importance of ASPs, there remains limited empirical evidence regarding their operational effectiveness, specific strategies, and impact on prescribing behaviors in community pharmacies. This study aims to evaluate the effectiveness of current ASPs implemented in community pharmacies, identifying factors that influence their success and areas requiring improvement. The primary objectives are to assess pharmacist knowledge, attitudes, and practices related to antimicrobial stewardship, measure changes in dispensing patterns pre- and post-ASP intervention, and explore the correlation between stewardship activities and antibiotic resistance trends within the community. A mixed-methods research design was adopted, combining quantitative and qualitative approaches to provide a comprehensive assessment. The quantitative component involved a cross-sectional survey administered to 250 licensed community pharmacists selected through stratified random sampling across urban and rural settings, ensuring diversity in practice environments. Data collection employed a structured questionnaire validated through pilot testing and expert review, capturing pharmacists’ knowledge levels, perceived barriers, and stewardship practices. In addition, retrospective analysis of pharmacy records over a 12-month period was conducted to evaluate changes in antibiotic dispensing patterns, focusing on the appropriateness and frequency of prescriptions. The qualitative component utilized semi-structured interviews with 20 pharmacists to gain deeper insights into contextual factors impacting ASP implementation and adherence. Data analysis involved descriptive statistics to summarize demographic data and knowledge scores, while inferential techniques such as multiple regression analysis identified predictors of stewardship effectiveness. Paired t-tests compared pre- and post-intervention dispensing patterns, assessing the impact of ASP activities. Thematic analysis of interview transcripts was carried out to identify recurring themes related to facilitators and barriers in implementing ASPs, guided by the Theories of Planned Behavior and Change Management Frameworks. Expected findings include a moderate level of pharmacist knowledge about antimicrobial resistance, with identified gaps in understanding of stewardship principles. The study anticipates observing a statistically significant reduction in inappropriate antibiotic dispensing following targeted ASP interventions, supported by improved pharmacist practices. Qualitative insights are expected to reveal organizational, educational, and patient-related factors influencing ASP adherence, including limited time, insufficient training, and patient demands. These findings are envisaged to fill existing gaps by providing empirically grounded evidence of ASP effectiveness in community pharmacy contexts and highlighting critical factors affecting implementation success. This research contributes to the existing body of knowledge by empirically demonstrating the impact of structured ASPs at the community level, emphasizing the role of pharmacists as key agents in antimicrobial stewardship efforts. It expands current understanding of behavioral influences and systemic factors that facilitate or hinder effective program deployment in community settings. The study's recommendations will include policy enhancements, training programs, and operational guidelines aimed at strengthening ASP adoption, ultimately informing stakeholders such as pharmacy regulatory bodies, healthcare policymakers, and community pharmacists. The study concludes that targeted, well-structured ASPs are instrumental in optimizing antibiotic use and mitigating resistance development. It underscores the importance of continuous education, supportive policies, and collaborative efforts among healthcare providers to sustain stewardship activities. Future research directions proposed include longitudinal studies to evaluate long-term outcomes and intervention-based trials to test innovative stewardship models tailored for community pharmacies.
