Patient Monitoring and Scheduling System — a Solution to Provide Safe Treatment to Right Patient

Department of Occupational Therapy, Shatin Hospital, Hong Kong

Introduction Tuesday, 3 May

Facing with an ever increasing turnover rate and increased fragility of inpatient in Shatin Hospital, finding an effective method
to improve accuracy in treatment prescription and improving patient safety is always our utmost concern.

Recent advancement of technology empowers us to have an innovative idea in addressing this issue. In 2014, we work
together with an IT company in designing and creating the patient monitoring and scheduling system (PMS). In this new
project, we designed the layout and display of the hardware and laid down the simple logistic in operation while the company
offers us the technical support in software and hardware development.

PMS is a computerised system for occupational therapist to manage daily treatment activities scheduling and provide vital
signs monitoring for patients. When using PMS, patient’s journey in occupational therapy starts from check-in to the system,
implementation of training activities, vital signs real-time monitoring, to the precautions alert and check out. This system can
also provide summary reports for therapist to review patient’s progress and update treatment accordingly.

The developmental and preparation phase took about a year. In July 2015, we started to carry out a PMS trial run in one of
our treatment rooms. After one month with almost daily updates, the programme started to run in a full time basis.

Currently we are developing the phase two PMS in other treatment rooms. From March 2016, PMS has replaced all paper
activity cards in prescription of training. From now on, every detail about our patients, including their diagnosis, precautions,
monitoring data, prescribed training and performance were stored in the hospital number as a barcode on their wristband.

Objectives

(1) To provide the right treatment to right patient within the right amount of time; (2) to minimise human error in vital data
capturing; and (3) to improve efficiency and accuracy of treatment scheduling and monitoring.

Major Components of PMS

(1) Tablet PC for prescription of training, precautions and monitoring; (2) handheld barcode scanner for recap of prescribed
instructions and data recording; (3) bluetooth gadgets for vital monitoring; (4) VGA TV for display of scheduling and monitoring
information; and (5) back-end server for centralised data analysis and management.

EOS — a Revolutionary Low-dose Imaging for Spine and Leg

EOS is an ultra-low-dose X-ray imaging system which is newly put into service in the Prince of Wales Hospital since August
2015. Our EOS system is also the first system that installed in Hong Kong. The EOS uses a Nobel Prize winning technology
that was invented by Professor Georges Charpark. According to studies, the radiation dose of EOS in spine imaging is
reduced by 50% to 85% when compared with digital radiography but maintaining a remarkable image quality. Moreover, it is
noted that there is about 95% radiation reduction when compared with basic computed tomography in similar scanning.

With the implementation of the EOS low-dose imaging system, patient suffering from adolescent idiopathic scoliosis (AIS)
is most benefited. AIS is commonly seen in teenagers aged from 10 to 18 (a radiation sensitive group), who require routine
imaging followup for every six months to assess the severity of disease and the efficacy of therapeutic brace. The EOS low-
dose imaging system can greatly reduce the hazardous effect of radiation and allow surgeon to have more complete and long
term evaluation.

Apart from the benefits in radiation dose reduction, EOS system provides a simultaneous bi-plane full-body scanning in a
standing functional position. The bi-plane data is important for building up a 3D model which can allow surgeon to have a 360
degree visualisation of the spine and lower extremities orientation. Furthermore, the auto-generation of 3D measurements
information gives a better understanding on the disease profile. Finally the standing acquisition of image data allows accurate
posture assessment of patient which is of utmost importance for surgeon to understand precisely the functional factors of
the spine or leg problem.

As this is a completely new imaging system and the 3D modeling techniques requires more human input, a work group
collaborating with orthopaedic surgeons is formed for the optimisation of the system.
