Flow Management System

Beyond state-of-the-art amenities, modern hospitals differentiate themselves by enhancing the experience for patients seeking diagnosis and treatment within the facilities. The quality of its medical services should be matched by the quality of its system and processes.

One of the most important touchpoints of a hospital is its outpatient operations. Nexus is designed to support the demands of complex outpatient operations to improve efficiency and deliver a patient-centric experience.

Nexus is an intelligent patient flow management system designed to improve patients' experience by facilitating their movement within and across facilities. The result is reduced wait time and improved staff productivity by reducing manual decisions required to run the entire outpatient operation effectively.


Global Dashboard

A queue dashboard shows a summary view of patients in a facility. Global Dashboard allows facility managers in charge of multiple facilities to switch between different dashboards without logging out and in.

Mobile Service Station

Nexus enables service staff to access via mobile devices so that they may be able to better serve patients by being on the move.

Facility Management

At the facility level, the facility administrator has the flexibility to configure unique operational parameters: facility timers, queue priority algorithm, wait time threshold, queue number skip count, ticker tape messages, service sequence, ticketing kiosk functions, queue number format, SMS notification configuration, service page layout. Also allows facility staff to refresh or restart their queue TVs.

One-Shot Timer

The generic one-shot timer function allows service staff to hold on to a patient for a defined time period, e.g. wait 10 minutes for eye dilation, after which a notification prompts the staff to take the subsequent actions.

Service Continuity

Nexus allows service staff to initiate an auto or manual transfer of a patient to another facility for another service, e.g. patient who starts from the Emergency Department can be transferred to Radiology for scans. The service staff can select either No Return, Auto Return or Auto Return to Me option.

HL7 and 3rd Party System Integration

Nexus is adaptable for 3rd party system integration via HL7, Web API or Web Scraping and has implemented the follow scenarios:

3rd party systems integration via HL7 within the hospital ecosystem to facilitate more integrated and intelligent operations
Hospital Information System integration via Web APIs for real-time patient demographic data retrieval
Lab E-Order System integration via Web APIs for retrieval of e-orders and update of test status and notes
Bed Management System/OT System integration via web scraping to retrieve patient bed status / procedure time

Multi-Campus & Multi-Facility Design

Nexus is designed to support multiple hospital sites and multiple facilities within each hospital by way of administrative configuration, all under the control of the central administrator. There is no limit on the number of sites or facilities which can be configured.

Multi-Factor Authentication

Nexus supports 2FA authentication via SMS or SingPass. For SMS 2FA, the customer has the option to implement either inclusion or exclusion rules. For inclusion rule, the system will enforce 2FA for the specified roles. For the exclusion rule, the system will bypass 2FA for the specified roles.

Automated Load Balancing

Nexus automatically load balances patient traffic between available service staff without a need to manually assign patients to specific counters. Eliminates the need for manual assignment and reduces patient wait time.

Single Queue Number

With a single queue number, a patient can receive different services within the same facility and across facilities. This reduces the time taken to get different tickets. The same ticket tracks the patient's journey across facilities.

Journal Log

The system logs all interactions for each patient's journey throughout the hospital's outpatient touchpoints. The journal records who at which touchpoint has interacted with which patient for what service and at what time. Hence makes it possible to deduce how long a service takes to complete. It allows management insight on the outpatient service performance. The Journal Log is searchable to retrace a patient's journey in real-time or in the past.

Service Sequence

Service Sequence allows each facility to define its own predefined path for a facility which provides multiple services. This eliminates the need for staff to know which next station to manually push the patient to as the system automatically routes the patient to the correct stations.

Special Alerts

At the Business Office stations, Nexus can detect and alert service staffs to attend to some types of patients, e.g. a patient has an operation scheduled within 3 hours or where a patient's designated room is ready for admission. In the latter case, the service staff could then initiate a transfer of the queue ticket to the Front Office porter worklist.

Special Timer Functions

In certain facilities, special timer functions can be created to assist the staff with a time-sensitive sequence of actions. For example, the GTT test at a lab could be initiated with a GTT time defined as 2 one-hour intervals between the start and end of the test.


Apart from a highly available backend, the user worklist and queue TVs implement auto-recovery, which auto reconnects when there's a breakage in network connectivity, effectively reducing recovery time and the need for manual intervention for transient infrastructural issues.

Fast In Fast Out

The hospital has the option to turn on FIFO mode, which ensures a patient who starts at a facility early will be accorded higher priority no matter which other facilities he visits on the same day.

HL7 Integration

Nexus' HL7 Integration module allows it to integrate with 3rd party systems within the hospital ecosystem to facilitate more integrated and intelligent operations.

Station Switcher

Users who work multiple roles can switch between service stations without logging out and in within the same facility or between facilities.

Mobile E-Ticketing

Patients can generate e-tickets and enquire on queue status directly from their mobile phones.

Dynamic Wait Time

System automatically computes patient wait time for their next service. The info can be shown on the TV or via their mobile phones, including number of patients ahead.
