Comprehensive Cost/Benefit Analysis and IoT Recommendations for Remote Patient Monitoring at eHA Clinics

1. Introduction

Remote Patient Monitoring (RPM) is pivotal in managing chronic conditions such as hypertension and diabetes, ensuring continuous care, and enhancing patient outcomes. For eHA Clinics, a network of Primary Health Care (PHC) facilities in Nigeria, implementing RPM for empaneled hypertensive and diabetic patients can significantly improve illness control, reduce complications, and ensure medication adherence. Leveraging Internet of Things (IoT) technologies—specifically LoRaWAN devices, LoRaWAN Gateways, Bluetooth Low Energy (BLE) devices, NB-IoT for backhaul and devices, and mobile LoRaWAN devices—can enhance RPM capabilities, streamline operations, and adhere to healthcare quality benchmarks set by the Joint Commission International (JCI) and HEDIS. This analysis explores cost-effective and viable IoT solutions tailored to the Nigerian context, focusing on achieving key performance indicators (KPIs) and optimizing quality improvement (QI), Quality Assurance (QA), and Quality Control (QC).
