Determination of the Enablers and Challenges in the Implementation of Pharmacy-based Antimicrobial Stewardship (AMS) Program in a Level 3 Hospital in Manila.

Abstract

Antimicrobial resistance (AMR) is a global public health threat that results from misuse and overuse of antimicrobials. The Department of Health (DOH) institutionalized the Antimicrobial Stewardship (AMS) Program in hospitals, based on the core elements (1) Leadership, (2) Policies, Guidelines, and Pathways, (3) Surveillance Antimicrobial Use (AMU) & AMR, (4) Action, (5) Education, and (6) Performance Evaluation to ensure rational use of antimicrobials and improve patient outcomes. The program implementation will require the involvement of the AMS clinical pharmacist to positively influence the success of the program's implementation. This study aims to identify the enablers and challenges as perceived by AMS clinical pharmacists in the implementation of an AMS program in a level 3 hospital in Manila. A quantitative descriptive study design was employed by administering an online 50-item survey questionnaire to AMS pharmacists, who have at least six (6) months of experience as an AMS pharmacist in the hospital. The survey questionnaire was validated by an expert consultant and underwent pre-testing (Cronbach α = 0.983) for acceptable internal consistency. Responses were collated, coded, and analyzed using median values and frequency distributions for each questionnaire item per Department of Health (DOH) Core Element. Items garnering a median of >3.50 up to 5 were considered as perceived enablers, while those ≤3.50 were identified as perceived challenges. Some perceived enablers by the AMS pharmacists include presence of a leader and/or clinician in the AMS team, Information Technology (IT) resource availability, clear roles of AMS pharmacists, readily available hospital AMS guidelines, engagement in AMR and AMU surveillance activities, regular performance of AMS interventions (e.g., IV-to-PO conversion, dose optimization, de-escalation of broad spectrum), regular monitoring and evaluating of prescriptions and prescribing behavior, and continuous education on infection, prevention, and control (IPC) and hygiene. On the other hand, some perceived challenges include insufficient funding, inadequate knowledge in interpreting antibiograms, lack of adequate and specialized training sessions, lack of coordination with medical and nursing staff to ensure timely drug administration and automatic stop order, prescribing of non-Philippine National Formulary (PNF) antimicrobials, lack of time to perform AMS activities, lack of qualified personnel, and lack of hospital management and information technology (IT) support. Empowering AMS clinical pharmacists is vital to addressing the perceived challenges and maximizing the perceived enablers to ensure the successful implementation of the AMS program in the hospital.
