En los centros sanitarios modernos, eficacia, fiabilidad, y los tiempos de respuesta rápidos son cruciales para la atención del paciente. Una de las herramientas de comunicación más esenciales utilizadas en los hospitales, Asilos, and other healthcare institutions is the Sistema de llamada de enfermería. These systems ensure that patients can quickly and effectively communicate with medical staff when they require assistance.

With advancements in technology, nurse call systems have evolved into three main types: Bus-based, IP-based, and Wireless. Each of these systems offers distinct benefits and is suitable for different hospital environments. This article explores these three technologies, their advantages, and their applications in medical facilities.

1. What is a Nurse Call System?

Un Sistema de llamada de enfermería is a communication network that enables patients to alert nurses and caregivers when they need help. Típicamente, patients activate the system by pressing a button, pulling a cord, or using a bedside remote. The system then transmits the request to a nurse station, a handheld device, or an overhead alert system, allowing medical staff to respond quickly.

• Improved Patient Safety – Patients can quickly call for assistance in emergencies.

• Increased Efficiency – Nurses can prioritize and manage patient needs more effectively.

• Better Communication – Reduces response time and improves hospital workflow.

Depending on the hospital’s infrastructure, budget, and needs, administrators can choose from bus-based, IP-based, or wireless nurse call systems.

2. Bus-Based Nurse Call Systems

Overview

Un bus-based nurse call system operates on a centralized control unit with a wired network structure. All patient stations, call buttons, and alarm indicators are connected through a bus line, a shared communication pathway that transmits signals between the devices and the central controller.

How It Works

• Each room or patient station is connected to a control unit via a low-voltage wired bus.

• When a patient presses the call button, the signal travels through the bus network to a nurse station.
• The system displays the room number, patient ID, or bed location at the nurse’s control panel.

Ventajas

✔ Fidedigno & Stable: Wired systems offer a consistent connection with minimal interference.
✔ Low Maintenance: Once installed, these systems require minimal upkeep.
✔ Cost-Effective: Compared to IP-based systems, bus-based systems generally have lower installation costs.

Disadvantages

✘ Limited Flexibility: Adding new devices requires rewiring, making expansions difficult.
✘ Installation Challenges: Requires structured cabling, which can be disruptive in existing hospitals.

Best for:

• Hospitals that prefer stable, wired communication.

• Facilities that do not plan to expand their system frequently.

• Locations with limited budget for IT infrastructure.

3. IP-Based Nurse Call Systems

Overview

An IP-based nurse call system leverages the hospital’s existing network infrastructure, utilizing Ethernet cables and the Internet Protocol (IP) for communication. These systems integrate with other hospital management systems, como las historias clínicas electrónicas (EMR) and hospital information systems (HIS).

How It Works

• Patient stations and call buttons are connected to the hospital’s LAN (Local Area Network).

• Calls and alerts are transmitted over the IP network, allowing nurses to receive notifications on computer terminals, mobile apps, or pagers.

• The system enables voice and video communication for direct interaction between patients and nurses.

Ventajas

✔ Scalability: Easy to expand by adding new devices without extensive wiring.
✔ Integration: Can be linked to other hospital systems (p ej., HIS, EMR, telemedicine).
✔ Monitoreo remoto: Allows nurses and doctors to receive alerts from anywhere in the hospital.

Disadvantages

✘ Higher Initial Cost: Requires investment in network infrastructure and IT maintenance.
✘ Potential Network Interference: System performance depends on the hospital’s network quality.

Best for:

• Large hospitals that require advanced monitoring and integration.

• Healthcare networks looking for remote access and data analytics.

• Modern facilities with existing IT infrastructure.

4. Wireless Nurse Call Systems

Overview

Un wireless nurse call system operates using radio frequency (RF) or Wi-Fi, eliminating the need for extensive wiring. This system is ideal for older buildings, temporary clinics, or nursing homes where wired solutions are impractical.

How It Works

• Patients use wireless call buttons or pendants to send alerts.

• The signal is transmitted via RF or Wi-Fi to a nurse station or mobile device.

• Nurses receive notifications on pagers, mobile phones, or central display screens.

Ventajas

✔ Easy Installation: No cabling required—perfect for retrofitting older hospitals.
✔ Flexible & Portable: Devices can be easily moved or added as needed.
✔ Cost-Effective for Small Facilities: Lower installation costs compared to wired systems.

Disadvantages

✘ Signal Interference: May be affected by walls, other electronic devices, or Wi-Fi congestion.
✘ Battery Dependence: Wireless call buttons and devices need regular battery replacements.

Best for:

• Small clinics, Asilos, and temporary healthcare units.

• Older hospitals where installing new wiring is challenging.

• Facilities needing quick deployment with minimal disruption.

5. Choosing the Right Nurse Call System

When selecting a nurse call system, healthcare administrators must consider several factors:

✅ Facility Size & Diseño

• Large hospitals benefit from IP-based systems due to their scalability.

• Older or temporary buildings may find wireless systems more practical.

✅ Budget & Installation Costs

• Bus-based systems are cost-effective but require cabling.

• IP-based systems offer advanced features but have higher initial costs.

• Wireless systems save on wiring costs but may require regular maintenance.

✅ Integration with Hospital Systems

• If a facility wants to connect the nurse call system with HIS, EMR, or mobile devices, un IP-based system is ideal.

• Bus-based systems are standalone and do not easily integrate with digital hospital networks.

✅ Reliability & Security

• Bus-based systems son highly reliable but limited in functionality.

• IP-based systems offer secure data transfer and advanced monitoring.

• Wireless systems need strong RF or Wi-Fi signals to ensure consistent performance.

6. Conclusión

Medical nurse call systems are essential for improving patient care, enhancing nurse efficiency, and ensuring fast emergency responses. Whether a hospital chooses a Bus, IP, or Wireless system depends on its needs, infrastructure, and budget.

• Bus-based systems are reliable, cost-effective, but less flexible.

• IP-based systems are modern, scalable, and highly integrative.

• Wireless systems offer convenience, easy installation, and mobility.

As hospitals continue to adopt new technologies, IP-based and wireless solutions are becoming more popular, providing real-time monitoring and seamless communication between medical staff and patients. Regardless of the choice, investing in an efficient nurse call system is a step toward better healthcare delivery and patient safety.
