Connecting Medical Devices, IT Systems, and Data in Hospitals: A Guide to the Connected Hospital

Modern hospitals rely on a wide range of digital systems and connected devices to support patient care and daily operations. A single patient journey can generate information from bedside monitors and medical devices, EHR/EMR platforms, laboratory and imaging systems, pharmacy applications, admission and discharge systems, and other clinical and operational tools.

The challenge is not necessarily a lack of technology. It is that these systems may operate separately, making it difficult to move information consistently between them. Different interfaces, data formats, and workflows can create gaps in how information is shared and accessed.

A connected hospital platform can help bring these technologies together, enabling information to move between systems and reach the people and applications that need it. An integrated healthcare platform can provide a common layer for connecting clinical, operational, and administrative systems, supporting more coordinated workflows and better access to information.

What is a Connected Hospital?

A connected hospital is a healthcare environment in which medical devices, clinical applications, hospital information systems, and data infrastructure can exchange information to support clinical and operational workflow.

Connectivity occurs at different level:

• Device connectivity

Medical devices such as patient monitors, ventilators, infusion systems, connected beds, and diagnostic devices can share relevant information electronically with other healthcare systems. However, the way devices connect and exchange data can vary depending on the device and technology used.

• System connectivity

Hospital systems can exchange information with one another, helping clinical and operational data move between different applications. For example, an EHR can connect with laboratory, imaging, pharmacy, medical device, and operational systems to support a more connected flow of information.

• Data interoperability

Data interoperability means that shared information can be understood and used correctly by another system, while retaining the right context and meaning. Healthcare standards help systems exchange data in a consistent way.

Why Hospital Data Becomes Fragmented

Hospitals often use technology from different vendors, purchased at different times and for different departments. EHRs, laboratory and imaging systems, pharmacy applications, medical devices, and operational tools may each have their own interfaces, data formats, and databases. Legacy equipment and proprietary interfaces can make integration more difficult, while separate clinical and operational systems may create additional data silos. Over time, hospitals can also accumulate multiple point-to-point integrations, making information flows harder to manage. Hospitals continue to use a mix of proprietary and standards-based approaches to exchange data.

Consider a bedside monitor that records a patient’s vital signs. Without appropriate integration, the workflow may look like:

Without appropriate integration, a clinician may need to read the monitor’s value and manually enter it into the EHR.

With suitable integration, the monitor can send the data through a n integration layer, where the relevant patient and context are checked before the information is made available in the EHR or another clinical application.

This can reduce manual data entry, but clinical validation and appropriate review requirements still re main important. Medical device interoperability must also support safe and effective exchange and use of information.

What Does an Integrated Healthcare Platform Connect?

An integrated healthcare platform can connect different types of hospital technology, helping information move between systems in a structured and useful way. This can include medical devices, clinical applications, operational systems, and data environments. The exact connections depend on the devices, systems, interfaces, and standards available.

• Medical Devices

Medical devices such as physiological monitors, ventilators, infusion devices, connected beds, anaesthesia equipment, and diagnostic devices can provide data to connected systems. Device connectivity can support the transfer and use of clinical and device information, although connection methods vary across equipment and manufacturers.

• Clinical Information Systems

An integrated platform can connect clinical systems such as Electronic Health Records (EHRs), Electronic Medical Records (EMRs), Laboratory Information Systems (LIS), Radiology Information Systems (RIS), Picture Archiving and Communication Systems (PACS), pharmacy systems, and clinical decision-support applications. This can help relevant patient information move between clinical workflows.

• Operational Systems

Integration can also extend to admission, discharge, and transfer systems, bed management, asset management, scheduling, and workflow or communication systems. Connecting these systems can help coordinate clinical and operational activities.

• Data and Analytics Environments

Appropriately integrated information can also support reporting, dashboards, operational analytics, quality-improvement initiatives, and approved research or data environments. This creates opportunities to use information from different parts of the hospital without treating each system as an isolated source.

How Medical Devices, IT Systems, and Data Connect

Connecting hospital technology is more than simply linking systems together. Information needs to move between medical devices, applications, and clinical systems in a way that preserves the information needed for it to be understood and used appropriately.

• Interfaces and APIs

An Application Programming Interface (API) provides a defined way for software systems to request, send, or exchange information. In healthcare, APIs can allow applications to access or share information without requiring them to understand how another system works internally.

• HL7 and FHIR

Health Level Seven (HL7) provides healthcare information standards, including HL7 FHIR (Fast Healthcare Interoperability Resources). FHIR is a widely used standard for electronically representing and exchanging healthcare information and is designed to support API-based data exchange.

FHIR is an important interoperability standard, but it does not by itself solve every healthcare integration challenge. Successful integration can also depend on implementation choices, data quality, security, workflows, and the capabilities of connected systems. Healthcare organisations may use different standards and implementation specifications depending on their needs.

• Integration Engines or Interoperability Layers

An integration engine or interoperability layer can act as a connection point between systems that do not communicate in exactly the same way. Depending on the platform and implementation, it may help receive, transform, route, and exchange information between different technologies.

The result is a more structured flow of information from devices and applications to EHRs, clinical workflows, dashboards, and other approved systems. The exact architecture and capabilities vary between healthcare environments.

What Are the Benefits of a Connected Hospital Environment?

A connected hospital environment can help information move more consistently between clinical, operational, and other healthcare systems. When relevant information is available across systems, teams may spend less time searching for information stored in separate applications and more time using it within their workflows.

• Less Fragmented Information

Integration can reduce the need to access multiple isolated systems to understand relevant patient or operational information. Bringing appropriate information together can provide a more complete view across workflows.

• Reduced Duplicate or Manual Data Entry

Where clinically and technically appropriate, connecting devices and systems can reduce some manual transcription and repeated data entry. It does not necessarily eliminate manual documentation or clinical review.

• Better Information Availability

Relevant information can become available closer to where clinicians and operational teams need it. Timely access to information can support more informed decisions and coordinated activities.

• More Coordinated Workflows

Connected systems can support information moving across departments and care processes instead of remaining within individual applications. This can help reduce information gaps between teams.

• Stronger Foundation for Analytics

Appropriately integrated and governed data can provide a stronger foundation for reporting, dashboards, operational analytics, quality improvement, and approved research or data initiatives.

What Should Hospitals Consider Before Building a More Connected Environment?

Building a more connected hospital environment starts with understanding how information needs to move, not simply adding more technology. Hospitals can explore several questions before deciding how to improve connectivity.

1. What systems and devices need to exchange information?

Start with important clinical and operational workflows. Identify which systems and devices need to share information and what information is actually required. This helps ensure integration addresses real workflow needs rather than technology for its own sake.

2. What interoperability capabilities already exist?

Hospitals can review existing interfaces, APIs, healthcare standards, and vendor capabilities. Standards such as FHIR can support electronic health information exchange, but the appropriate approach depends on the specific use case and systems involved.

3. Where are manual workflows creating friction?

Look for areas where information is repeatedly copied, re-entered, or retrieved from separate systems. These workflows may highlight opportunities for better connectivity.

4. How will identity and context be handled?

Information needs to be associated with the right patient, encounter, device, and workflow. Patient identity matching is an important part of interoperability because information from different systems must be linked to the correct patient record.

5. How will connectivity be governed and secured?

Connectivity also requires appropriate privacy, security, access controls, and governance. IT, clinical engineering, security, data, and clinical stakeholders should have a role in shaping how systems connect and exchange information.

Connected Hospitals Are Built on Interoperability, Not More Technology

Hospitals already have significant technology in place, from medical devices and EHRs to laboratory, imaging, pharmacy, and operational systems. The bigger opportunity is not necessarily adding more technology but helping existing and future technologies exchange and use information more effectively. Interoperability supports the electronic exchange and use of health information across different systems and devices.

A connected environment brings together medical devices, IT systems, healthcare data, and workflows so that relevant information can move between the places where it is needed. A connected hospital platform can provide part of this integration, while an integrated healthcare platform may bring multiple clinical and operational systems into a more coordinated environment.

Ultimately, a connected hospital is less about adding another isolated technology and more about creating an environment where devices, applications, information, and people can work with greater continuity.

Organizations exploring connected hospital strategies can begin by mapping where devices, systems, and data currently interact, and where interoperability gaps remain.
