RTLS for Hospital Supplies vs. Vision AI: Which Is More Efficient?

Keeping hospital supplies at the right levels is crucial for smooth operations and high-quality patient care. When inventory runs low or goes missing, the result can be costly delays, added expenses, and a potential risk to patient well-being. This is why many hospitals have relied on Real-Time Location Systems (RTLS) to keep tabs on where equipment and supplies are located. RTLS provides a big-picture view of item locations and movements, helping to cut inefficiencies caused by misplaced assets.

At the same time, healthcare supply chains are growing more complex, and there’s increasing interest in computer vision AI solutions to track supplies more precisely. These AI-driven inventory management systems use cameras to count stock levels automatically, monitor real-time usage tracking, and create more accurate reorder alerts. But rather than replacing RTLS altogether, many healthcare providers are exploring how these two approaches can work together—leveraging location tracking from RTLS while benefiting from the precise inventory monitoring of AI-powered computer vision.

Understanding RTLS for Hospital Supplies

What Is RTLS?

Real-Time Location Systems (RTLS) track and locate medical supplies, equipment, and even personnel in a facility. Using technologies like RFID, Wi-Fi, infrared, or Bluetooth Low Energy (BLE), RTLS continuously updates where assets are located. This makes it an essential component of a hospital inventory tracking system, especially for larger, mobile items.

How RTLS Works

RTLS begins with a three-step process that ensures accurate asset tracking across the facility:

Tags: The process starts by attaching tags to supplies or equipment. Typically, RFID tags are used for smaller items, while Bluetooth or Wi-Fi tags are ideal for larger equipment. These tags serve as unique identifiers for each asset.
Sensors: Next, strategically placed sensors throughout the facility detect these tags. The sensors capture the location data and send it to a central system, ensuring continuous updates on asset whereabouts.
Tracking Software: Finally, the collected data is aggregated by tracking software. This software provides hospital teams with a real-time view of asset locations through an intuitive dashboard or mobile application, enabling quick and informed decisions.

Benefits of RTLS in Healthcare

Building on these technological foundations, RTLS offers several significant advantages:

Faster equipment retrieval: With real-time location data, staff spend less time searching for equipment—studies indicate an average time saving of 20 minutes per shift.
Improved patient safety: When critical supplies and equipment are readily available, hospitals are better prepared to respond during emergencies.
Reduced theft or lossEnhanced location visibility can reduce asset loss by up to 40% in some hospitals.
Preventative inventory checks: By knowing the precise location of items, hospitals can perform proactive checks, helping to prevent shortages before they occur.

Limitations of RTLS in Detailed Inventory Tracking

While RTLS is highly effective for tracking asset locations, it does have some limitations:

Manual counts still needed: RTLS does not automatically track the exact stock levels in supply rooms, meaning that manual inventory counts remain necessary.
Limited visibility into usage: Although it excels at locating items, RTLS does not capture detailed data on how many items are used during procedures.
Signal interference: The accuracy of RTLS can be affected by building layouts or construction materials, particularly in older facilities.
Less predictive power: Without additional tools, RTLS alone offers limited insights into future demand patterns, which are crucial for comprehensive inventory management.

How Computer Vision AI Adds Another Layer of Insight

What Is AI-Powered Computer Vision?

With computer vision AI, smart cameras watch supply bins and shelves in real time. The system detects when items are taken or restocked, noting exact counts and generating automated reordering signals if stocks drop below preset levels. This approach provides a higher level of detail for medical inventory automation, helping hospitals reduce stockouts and over-ordering.

How Computer Vision AI Works

AI-enabled cameras – Monitor shelves, bins, or storage areas (typically mounted above supply areas)
Advanced AI-algorithms – Detect low stock levels or changes in bin fullness using machine learning models trained on thousands of supply item images
System integrations – Connect with ERP, EHR, and procurement software to update inventory and trigger reorders automatically
Analytics dashboards – Offer real-time views of supply usage and generate predictive insights based on historical consumption patterns

Real-World Example

At a regional hospital in Florida, computer vision AI monitors high-value cardiac catheterization supplies. The system automatically detects when items are removed and updates inventory counts without staff intervention, reducing manual counting time by 94% and improving inventory accuracy from 85% to 98%. This highlights how AI-automated hospital inventory tracking systems can drastically cut labor hours and improve healthcare supply chain management.
