Computers on Wheels / Workstations on Wheels

COWs (Computers on Wheels) and WOWs (Workstations on Wheels) are mobile computer systems designed to bring digital access directly to the point of care, most commonly in healthcare settings such as hospitals and clinics. These mobile workstations are equipped with a computer, monitor, keyboard, and often additional medical equipment or storage, mounted on a wheeled cart for easy transportation.

These devices enable healthcare professionals to access and update patient records, input data, manage medications, and perform administrative tasks right at the patient's bedside. This mobility helps improve workflow efficiency, enhance patient care, and reduce documentation errors.

The terms COWs and WOWs are often used interchangeably, though some facilities may prefer WOWs to avoid negative connotations from the acronym "COW."

How Do COWs / WOWs Work?

COWs/WOWs function as mobile computing stations, integrating with hospital networks and electronic health records (EHR) systems through secure wireless connections. They provide healthcare staff with real-time access to critical patient data, allowing updates and orders to be entered at the point of care.

Typical features include:

• Battery-powered systems to allow operation throughout a shift without needing frequent recharging.

• Adjustable heights to accommodate different users and environments.

• Integrated barcode scanners for medication administration and patient identification.

• Lockable compartments for medications or supplies.

• Lightweight and ergonomic designs to reduce strain during transport.

Some advanced models also offer features like antimicrobial surfaces to reduce infection risk and hot-swappable batteries for continuous use.

Structure and Components of COWs / WOWs

The core components of a COW/WOW typically include:

• Computer Hardware: Often a compact desktop or all-in-one computer system with sufficient performance for clinical applications.

• Display Monitor: A high-resolution screen, sometimes with touchscreen capabilities for ease of use.

• Power Supply: Long-life batteries or hot-swappable battery systems to allow uninterrupted mobility.

• Input Devices: A keyboard and mouse, typically secured to the workstation.

• Cart Hardware: A mobile, ergonomic cart with adjustable height, storage compartments, and wheels designed for smooth movement across clinical environments.

• Connectivity: Secure Wi-Fi connectivity for integration with hospital systems and EHR platforms.
