QA/QC Metrics for EHA Clinics - 9 - Waste Management

Comprehensive Cost/Benefit Analysis for Implementing IoT-Based Biohazard Waste Management at eHA Clinics

Introduction

eHA Clinics, a leading Nigerian-based Health Clinic organization, operates numerous Primary Health Care (PHC) facilities commercially. Effective biohazard waste management is critical for maintaining a safe and compliant healthcare environment, minimizing infection risks, and adhering to international quality benchmarks such as those set by the Joint Commission International (JCI). This analysis explores the implementation of IoT technologies—specifically LoRaWAN devices, LoRaWAN Gateways, BLE devices, NB-IoT for backhaul and devices, and mobile LoRaWAN devices—for biohazard waste management within eHA Clinics' ecosystem.

Use Case Description: Biohazard Waste Management

Key Areas:

Collection and Disposal Efficiency: Ensuring timely and safe collection, transportation, and disposal of biohazard waste to prevent contamination and comply with safety standards.
Monitoring Waste Levels: Tracking the fill levels of biohazard waste bins to optimize collection schedules and prevent overflow.
Compliance and Documentation: Maintaining accurate records of waste generation, handling, and disposal to meet regulatory and accreditation requirements.

Current QA/QC Processes:

Biohazard waste is disposed of in designated bins across various rooms.
Stewards wear appropriate PPE to collect waste when bins are filled or at least once daily.
Waste is weighed, kept in a temporary holding bin, and incinerated daily.
In the Kano clinic, waste is transported to the foundation every other day for incineration.

Proposed IoT Enhancements:

Automated monitoring of waste bin fill levels with real-time alerts.
Integration of waste management data into the Odoo system for streamlined documentation and scheduling.
Use of mobile IoT devices to track waste transportation and ensure timely disposal.
