Emerging Trends In Planning And Designing In Indian Hospitals
Dr K B Sood
Hospital
is the most visible face of the healthcare industry. It handles the dynamics
of life and death situations during the process of rendering healthcare. Peter
Drucker, the management Guru has said, Hospitals are the most complex
human organisation ever devised. Today, hospital buildings are considered
the most complex building forms. Integration of developing technologies into
healthcare delivery is making hospital buildings more complex. Therefore, planners
and designers of hospitals must be conversant with emerging trends in the fields
of technological developments, which shall be deployed in foreseeable future.
They must understand the complexity of integrating these technologies with the
building systems and forms, to create hospitals where the healthcare provider
can utilise these comfortably to deliver most appropriate healthcare.
This process had started by middle of 19th century when new emerging technologies
like X-ray machines, new drugs and better instrumentation was integrated into
the healthcare delivery. The pace of integration of technology was slow and
deliberated at length. But encouraged by the results, healthcare providers started
adopting new technologies at a faster pace, so much so, that in middle of 20th
century, it was said that the hospital building has become obsolete by the time
they are built.
It was at this time that hospital planners evaluated the emerging trend in technological
developments in various fields like Space Technology, Information Technology,
Aviation Technology, etc, and made a forecast for the emerging trends, which
may soon be seen in hospitals. These technologies were integrated with existing
healthcare delivery models and the new healthcare delivery models that emerged
were tested and if found useful, were made part of hospitals. This required
that all hospital planning consultants keep a track of all emerging trends in
various developing technologies. As and when the trends start finding an application
in healthcare delivery, the hospital buildings are ready to adapt to them without
many structural changes.
Let us look at these emerging trends as they are available to us for planning
and designing Indian hospitals in the next three to five years. We shall group
these trends into three categories.
- Technology trends which directly affect delivery
of healthcare.
- Technology trends which affect hospital engineering
and support services and thereby indirectly affect the delivery of healthcare.
- Non-technology trends which directly affect delivery
of healthcare.
In this article, we will discuss the Technology Trends Directly Affecting Healthcare
Delivery.
Digitisation of Hospital Equipment & Processes
Imaging services, especially radiology, has now been fully digitised. Physiology
monitors have been digitised. as well as clinical laboratory. The patient file
is being digitised. This has also enabled hospitals to archive full patient
files on hospital servers to be shared between various healthcare providers.
After digitisation, virtual doctors shall become a reality. There shall be centralised
control rooms to monitor clinical and administrative data. Digitisation will
enable hospitals to become paperless and film-less. Patient files shall be issued
as smart cards. The doctors, on ward rounds, shall carry a laptop and accessories
on a trolley and review patient data online. The doctor orders shall be transformed
into hospital vide activities on real times basis. Even the prescribed treatments
can be evaluated for incompatibility, patients allergy history, past history,
etc.
This will provide maximum benefit to the patient being evacuated to a hospital
because the digitisation will enable patient monitoring and possibly, provisioning
of critical care from the start point. When standardised, it shall be most useful
for cases of heart attack where Time is Muscle. By the time patient
reaches the hospital, the latter shall be geared to provide all needed services
immediately.
This will impact the way cross consultations are carried out because after digitisation,
geographical distances shall lose their meaning. It shall also enable vertical
integration across healthcare providers in primary care, secondary care and
tertiary care as well as across healthcare providers in rural centres and in
specialised centres located anywhere in India.
Hospitals have to gear up to meet the challenge of digitisation of patient data
in terms of digitised equipment, interpretation, staff skills and training.
Essentially, it shall require deployment of optical fibre networks within the
various departments of the hospital for very fast transfer of data. It shall
also require broad band connectivity across majority of healthcare providers
in India to realise the full potential of digitisation. This shall specially
require evaluation of interference across various cable and data transfers.
It shall also require deployment of ambulances, which shall provide critical
care while moving and will need proper communication links on the move. We feel,
if this happens, some staging stations shall need to be created whenever the
patient is being evacuated long distance say over 100 Km.
To make future hospitals compatible with older machines or less digitised hospitals,
some additional equipment like film scanners, film printers shall also be installed
all across the chain of hospitals and other facilities in a hospital group or
at state level or national level.
We believe that this trend is going to affect all hospitals, small or big in
the next three to five years because digitisation also has been reducing the
costs and all kinds of hospitals shall gradually upgrade to digitised equipment
for up-linking themselves to various networks for various purposes like insurance,
cross consultations, tele-medicine, etc.
Optical Coherent Reflectometery
Optical Coherent Reflectometery is the integration of infra red or lasers with
guide wires to visualise as well as treat obscure lesions when conducting any
intervention procedure on any organ using various systems of minimally invasive
procedures or surgeries. This will enable superior management of 100 per cent
coronary blocks as well as other vascular accidents and prevention of vascular
accidents on table during procedures. This requires integration of an additional
monitor in cath labs, vascular labs and operating rooms to beam the images as
generated by the addition of electromagnetic rays. At times, it shall involve
placing the standard monitor rails, if the pendants are not deployed.
Hospitals have to gear up by providing adequate interstitial area over false
ceiling, which can take extra rail mounts. This requires proper planning at
structural design stage to plan the structural beams in a manner that it causes
least interference with other accessories in the room. This is a trend that
will have its maximum impact on tertiary care hospitals.
Computer Assisted Surgical Planning & Robotics
This involves deploying the computers to support precision surgical techniques
for all complex procedures like hip implant or coronary by-pass surgery thereby
reducing the operating time & better outcomes. In fact, it shall become
possible for the Surgeon to practice the proposed surgery by deploying
on-screen surgery, plan the rational activities for problem areas, determine
activities for support team including a robot, if available, and improve the
results of surgical intervention.
It shall require integration of an additional robotic control room in surgical
operating rooms. At a later date when stem cell therapy has been approved, another
room for a bio-reactor may be needed along with the robotic room for transferring
the scaffoldings to the patient from the Bio-reactor. Adequate considerations
for nosocomial infections due to presence of robots in the operating room need
special mention here. The operating room planning must be simulated to check
activity traffic, robot movement and placement of trolleys for providing a well
laid out work area for the surgeons. This is a trend that will have its maximum
impact on tertiary care hospitals.
Image Guided Surgery
Image Guided Surgery is integration of Diagnostic Monitoring Operative
Technologies. The operating room shall have combined operating table with a
CT Scanner workstation or a Vascular Intervention workstation. It shall provide
intra operative use of these workstations thereby reducing trauma, enhance surgical
precision and improve surgical access to literally every cell in the human body.
The process of treatment planning shall be monitored by a computer and based
on artificial intelligence models for online evaluation of treatment modalities
may be across the world in multiple centres. The concept is not very
new as Operating Room have been using mobile X-ray machines or ultrasound for
making diagnostic or therapeutic studies while surgery is being performed. But
the new modalities, which are being used, require much more technical back up.
This shall totally change the planning of Surgical Suites and Vascular Laboratories.
In addition to addressing the concerns of nosocomial infections, it shall have
to meet the installation requirements for scanners or flat panel vascular Laboratory
in the Operating Room. The Operating Room shall have to interface with control
rooms and panel rooms and meet the scatter radiation safety norms. The surgical
techniques shall also be realigned to work with radiation safety screens. This
is a trend that will have its maximum impact on tertiary care Hospitals.
Virtual ICUs and Deployment of Robots in ICUs
Digitisation of Physiological Monitors, Cameras, Pumps, Ventilators and other
accessories have made it possible to deploy robots to assist the ICU nurse to
render intensive care more effectively.
First step in this direction is creation of Virtual ICU where a control room
is created. In Virtual ICU, a Critical Care Internist monitors a large number
of patients with the help of computers and monitors. The patient data and live
images from various ICUs in a given hospital or across a number of Hospitals
are constantly monitored and evaluated for variation from set benchmarks. These
are generally missed out by the staff on duty due to human factors of stress
and fatigue. The Critical Care Internist, with the help of two-way audio-video
communications, helps the staff deployed in ICU to monitor the patients and
effects of therapy in more intensive manner.
Once the protocols of Virtual ICU have been standardised, a walking robot can
be deployed to assist ICU staff to carry out many of the repetitive activities
in an efficient manner. This shall not only reduce the cost of care because
the expensive Critical Care Internist resource is shared across a larger number
of beds, it improves the outcome of intensive therapies by reacting faster to
various alarms and by providing adequate instant support to ICU staff.
Hospitals have to gear up by providing adequate number of data ports, audio-video
communication ports and plan the ICU layout in such a manner that unobstructed
view of the patient at all times is possible.
We believe that this trend is going to affect hospitals, which have provided
ICUs, small or big in the next three to five years because virtual ICUs provide
for a far superior care at a reduced cost.
Integration of Various Diagnostic Modalities Into A Single
Machine
The CT Scanner has integrated Gamma camera and the MRI Scanner has integrated
PET scanner. This is being done to reduce the diagnostic time of the patient.
Hospital laboratory already has such machines, which perform tests across various
organ systems from same sample of blood.
Easy & Functional Mobility of Patient & Critical
Care Equipment
One of major problems in rendering critical care is managing the critical care
equipment that is used to provide infusions, ventilator support, monitors, etc.
When patient is moved from the ambulance to triage station to ward or operating
room, these present a major problem for provisioning of continuous care. Though
it is being managed with success, the modalities involve deploying additional
staff and lot of special care during transits.
Development of Satellite Care Systems coupled with Standard Docking Stations
provides for provisioning of standardised equipment at all places. The critical
care equipment moves with the patient attached to trolley or bed with its captive
power and gas supply and in ICU, triage station or operating room, it is docked
on to special pendants which provide total connectivity at the turn of a knob.
The docking station provides for changeover from cylinders or battery power
as available in Satellite Care Systems to centralised services at the turn of
a knob. Simultaneously, the battery in Satellite Care Systems is put on charging
mode. A single attendant can move the patient over a reasonable distance without
any fear of any mishap.
This trend is going to become the universal standard for movement of critical
patients., affecting all hospitals, small or big in the next three to five years.
Hospitals need to plan for a comprehensive set of piped medical gases, electrical
services and data cable provisioning at all docking stations for satellite care
systems. It must also consider sanitation requirements when the satellite care
systems are moved into clean or sterile zones.
