Connected medical devices are quietly transforming how hospitals deliver care, moving inpatient-level treatment from hospital beds directly into patients' homes. The Internet of Medical Things (IoMT), a network of connected medical devices and software applications that collect and transmit health data automatically, has moved beyond experimental pilots into active healthcare infrastructure at leading medical centers. The global IoMT market stood at $286.77 billion in 2025 and is projected to exceed $2,294.87 billion by 2034, reflecting explosive growth as healthcare systems embrace remote monitoring and home-based care .

What Exactly Is the Internet of Medical Things?

IoMT refers to a network of connected medical devices and software applications that collect, exchange, and act on health data with minimal manual input. These devices capture clinical signals like vital signs, glucose levels, electrocardiogram (ECG) readings, medication adherence, and patient location, then transmit that data to healthcare IT systems such as electronic health records (EHRs), clinical dashboards, and hospital information systems that care teams use in their daily practice. The software layer matters as much as the hardware itself, analyzing incoming device data to enable remote diagnostics, continuous monitoring, and personalized treatment at a scale no manual workflow could replicate .

How Are Hospitals Using Connected Devices to Monitor Patients at Home?

IoMT devices enable continuous remote patient monitoring (RPM) of vital signs such as heart rate, blood pressure, glucose levels, and oxygen saturation without patients leaving their homes. A diabetic patient using a Dexcom G6 continuous glucose monitor (CGM), for example, transmits real-time glucose readings directly to their care team. The physician sees trends, adjusts medication, and intervenes without the patient needing to schedule an in-person visit .

This IoMT-based RPM has allowed the hospital-at-home (H@H) model to gain significant traction. Mass General Brigham is actively shifting 10% of its medical patients to home-based care, backed by the Centers for Medicare and Medicaid Services (CMS) Acute Hospital Care at Home initiative, which permits hospitals to deliver inpatient-level care outside their walls. Within hospital walls, nurses monitor stable patients remotely, optimize their visits, and prioritize the needs of critical patients while effectively monitoring those in general wards. In conditions of workforce shortage, this approach prevents nurse burnout while ensuring proper care for inpatients .

What Types of Connected Medical Devices Are Being Deployed?

IoMT devices span a wide range of hardware and are typically grouped into five categories based on where they operate. Understanding these categories helps explain how different settings benefit from connected technology :

• In-Home Devices: Smart pill dispensers, connected blood pressure monitors, glucometers, connected inhalers, and smart medical beds support ongoing care without clinic visits, particularly valuable for patients with chronic diseases and the elderly. Personal emergency response systems automatically alert care teams when a patient experiences an emergency at home.
• Wearable Devices: Consumer-grade devices like fitness trackers, Apple Watches, and Fitbits track wellness metrics for personal use, while medical-grade devices like Abbott's FreeStyle Libre continuous glucose monitor are regulated, clinically validated tools used under professional guidance that measure interstitial glucose in real time and transmit readings directly to care teams.
• Mobile Devices: Tools like KardiaMobile by AliveCor pair a physical device with a smartphone application connected to hospital systems, using Bluetooth to communicate with clinical systems on the move and enabling medical-grade electrocardiogram (EKG) recordings that detect atrial fibrillation, bradycardia, and tachycardia.
• Public or Community Devices: Telehealth kiosks equipped with video displays, HD cameras, and integrated medical instruments like blood pressure cuffs and glucose monitors enable full remote consultations in public spaces and underserved areas, bringing primary care access to populations that lack it.
• In-Hospital Devices: Connected infusion pumps, sensor-equipped beds, wheelchairs, and monitoring equipment integrate into systems that clinical staff can oversee from a central dashboard, with alerts firing automatically on abnormal readings to decrease response time.

The distinction between consumer-grade and medical-grade wearables matters significantly for procurement and compliance. Medical-grade wearables carry stricter certification requirements and integration obligations than consumer devices, making them more suitable for clinical decision-making .

Steps to Implement IoMT in Your Healthcare Organization

Healthcare leaders considering IoMT adoption should follow a structured approach to ensure successful integration and patient safety :

• Assess Your Current Infrastructure: Evaluate existing healthcare IT systems, EHRs, and clinical dashboards to determine compatibility with IoMT devices and identify integration requirements before selecting hardware.
• Identify Clinical Use Cases: Determine which patient populations would benefit most from remote monitoring, such as those with chronic diseases, elderly patients, or those suitable for hospital-at-home programs, to prioritize deployment.
• Address Regulatory and Compliance Requirements: Understand that different device categories come with their own regulatory considerations; medical-grade devices require stricter certification than consumer devices, and integration obligations vary by device type.
• Plan for Data Integration: Ensure your software layer can analyze incoming device data to enable remote diagnostics and personalized treatment, as the software matters as much as the hardware itself.
• Consider Workforce Impact: Evaluate how remote monitoring will affect nursing workflows, recognizing that IoMT can prevent burnout by allowing nurses to prioritize critical patients while monitoring stable ones remotely.

Why Is the IoMT Market Growing So Rapidly?

The explosive growth of the IoMT market reflects several converging trends. Healthcare systems face workforce shortages, making remote monitoring an attractive way to maintain care quality without proportional increases in staffing. The direct-to-consumer (DTC) healthcare model is gaining popularity, and IoT solutions are becoming a staple for those offering alternatives to conventional healthcare. Additionally, regulatory support like the CMS Acute Hospital Care at Home initiative is creating pathways for hospitals to deliver inpatient-level care outside traditional settings, accelerating adoption of connected devices that make such models feasible .

The projected growth from $286.77 billion in 2025 to over $2.2 trillion by 2034 suggests that IoMT will become as fundamental to healthcare infrastructure as electronic health records are today. For patients, this means more personalized monitoring, fewer unnecessary hospital visits, and the ability to receive high-level care from home. For healthcare systems, it means better resource allocation, reduced burnout among clinical staff, and the potential to serve more patients with existing capacity .
