Comprehensive Cost/Benefit Analysis and Business Case for Implementing IoT Solutions in eHA Clinics’ Antimicrobial Stewardship Program
1. Introduction
Antimicrobial stewardship (AMS) is critical for combating antibiotic resistance and optimizing patient outcomes. For eHA Clinics, achieving the JCI benchmark of inappropriate antibiotic prescriptions below 10% (MMU 1.1) requires a robust approach to ensure compliance and minimize errors. Leveraging ICT and IoT technologies, such as Clinical Decision Support Systems (CDSS), BLE devices, LoRaWAN, and other automation tools, can enhance prescription appropriateness, streamline audits, and reduce manual workload.
This business case outlines strategies and technologies to strengthen AMS processes, with high Return on Investment (RoI) outcomes tailored to eHA Clinics' operational realities and scalable across Nigerian PHCs.
2. Current Antimicrobial Stewardship QA/QC Processes
Existing System:
- Second Check by Pharmacy: Pharmacists validate prescriptions for appropriateness.
- Expert Consultations: Providers consult senior colleagues when uncertain.
- Audits and Feedback: Trained auditors assess compliance and provide individual and team feedback.
Challenges:
- Time-Consuming Manual Audits: Labor-intensive and prone to delays.
- Human Error: Dependence on subjective judgments can affect accuracy.
- Scaling Limitations: Manual processes are resource-heavy for broader implementation in PHCs.
3. Potential IoT Solutions
a. Clinical Decision Support Systems (CDSS)
- Integration of CDSS with EMR Systems
- Real-Time Recommendations: CDSS analyzes patient data (symptoms, history, diagnostics) to suggest appropriate antibiotics.
- Automated Dosage Checks: Cross-references with patient-specific factors such as weight, age, and comorbidities.
- Automated Alerts for High-Risk Prescriptions
- Triggers alerts for inappropriate prescriptions, reducing human error.
- Provides evidence-based suggestions for alternative treatments.
b. IoT-Enabled Monitoring and Feedback Systems
- Smart Prescription Pads
- BLE-enabled devices track and log prescription activity in real-time.
- Sends prescription data directly to pharmacy and CDSS for validation.
- Automated Auditing Tools
- LoRaWAN sensors collect prescription and patient data from decentralized PHC facilities for centralized audit.
- AI-powered analytics assess trends in prescription errors and identify training needs.
c. Automation in Feedback Loops
- Real-Time Feedback to Providers
- Dashboards provide instant feedback on prescription appropriateness.
- Notifications for flagged prescriptions ensure timely corrective actions.
- Team Compliance Reporting
- Aggregates data to generate compliance trends and actionable insights for team training.
