Trends in Healthcare: Nurse Call Devices

“Trends in Healthcare” is a recurring series that focuses on exciting new designs and technologies we’re seeing in healthcare projects and provides best practices on how to ensure that these latest trends are accessible to persons with disabilities. We build on the wealth of knowledge we gain from working with healthcare design teams, construction crews, and practitioners to provide practical solutions for achieving accessible healthcare environments.


According to the U.S. Centers for Disease Control and Prevention (CDC), falls account for 3 million injuries treated in emergency rooms, 800,000 hospitalizations, and 28,000 deaths each year in the U.S. One in five falls cause serious injuries such as concussions/traumatic brain injuries and hip fractures. Not only is this a public health concern, it is extremely costly. According to the CDC, medical costs directly related to injuries resulting from falls totaled more than $50 billion in 2015.[1] Within hospitals and long-term care facilities, effective implementation of interventions and design strategies to reduce patient falls are key to increased patient safety and decreased medical costs. However, it may not be possible to eliminate patient falls altogether, so features like a properly installed nurse call system can be life changing.[2]

Accessible Nurse Call Stations

Most state and local standards and regulations require nurse call devices in each public toilet room and within inpatient bath, toilet, and shower rooms.[3,4] Where provided in spaces required to be accessible, the nurse call device must also be accessible. An accessible nurse call device is one that meets the following requirements:

  • All operable parts, including call reset switches, are within accessible reach range (15-48″ AFF);
    • NOTE: Determining compliant mounting height requires coordinating with the location of operable parts on the specific model used.
  • Operable parts do not require tight grasping, pinching, or twisting of the wrist to operate; and
  • Operable parts can be activated with no more than 5 pounds of force.

The location of operable parts differs between models of nurse call devices. It is important to determine mounting location based on the specific model of device being used.

While these criteria appear straightforward, proper placement of nurse calls can become complicated when coordinated with minimum grab bar clearances and additional requirements under FGI, NFPA 99, NFPA 70, Ul 1069, UL 2560, and other local codes.

Typically, nurse call devices are found on the side wall of the water closet, where a grab bar and toilet paper dispenser are also installed. We often see these devices mounted above the horizontal grab bar, where they interfere with the following clearances required at the grab bar:

  • The top of the grab bar must be mounted 33-36 inches above the floor
  • A minimum clearance of 12 inches must be provided above the top of the grab bar; and
  • A minimum clearance of 1½ inches must be provided below the bottom of the grab bar.

When these grab bar clearance requirements are overlaid with the accessible reach range requirements for the operable parts of the nurse call device, it becomes challenging to comply with both. Achieving compliance with the nurse call device mounted above the grab bar depends upon the model of device used and the precise installation of the device and grab bar.

As installed, the nurse call device obstructs the 12 inch minimum clearance required above the horizontal grab bar.

Best Practice

As a best practice, we recommend mounting nurse calls below the grab bar with at least 1½ inches between the top of the device and the bottom of the grab bar. Regardless of the model of device installed, this mounting location will ensure compliant grab bar clearances while simultaneously enabling all operable parts of the nurse call device to be located within the 15-48 inch reach range. Installing the nurse call device below the grab bar also reduces the likelihood of false alarms, which can be triggered when patients unintentionally lean against the device while using the grab bar.

Locating the nurse call device below the horizontal grab bar allows compliance with both grab bar clearances and accessible reach range requirements.

It is also critical to coordinate the mounting location of the nurse call device with the location of the toilet paper dispenser. The toilet paper dispenser must be mounted 7-9 inches from the front edge of the water closet; the nurse call device cannot obstruct the dispenser. Consideration must be given to the type and size of the specified toilet paper dispenser to determine the location of the nurse call station.

Relocating nurse calls to meet accessibility requirements post construction can be costly – the installation of a nurse call system can vary from $7K to $30K, depending on the specific model and the size of the facility. By following the best practices noted above, designers can address potential problems before they arise, avoiding the need to retrofit after construction is completed.
