1/23

Healthcare Technology Assessment (HTA)

systematic evaluation of properties, effects or

other impacts of health technology

address the direct and intended consequences

of technologies as well as their indirect and

unintended consequences

improving the quality of health care


2/23

Given Situation

Area where flood is likely to occur

to find measures and solutions to prevent losses

and damage to medical equipment in hospital


3/23


4/23

1. Warning System & Awareness of

Flooding Hazards Factors affecting drainage system:

1. Mud and slit

2. Rubbish, large object and tree fragments

could affect flow paths and could bring unexpected flow tocertain section of the drainage system

local flood warning systems installation

The warnings are disseminated through flood sirens or

through automatic telephone calls to the hospitalsrepresentatives.

Aim: To alert crowd before flood occurs so as to takeprecautionary measures


5/23

2. Avoid placing medical devices on

the ground floor Water can cause serious damages to medical devices

Raise medical devices above the anticipated flood level willhelp prevent damages to the devices.

Helps in avoiding potential fire from short circuits whichmight cause by the flood.

If it is unavoidable (huge machines, immovable devices),disconnect all the devices, unplug them and turn off thebreakers, only if this can be done in safe manner.


6/23

3. Raise Electrical System Components

Electrical system components, including service panels(fuse and circuit breaker boxes), meters, switches, andoutlets, are easily damaged by flood water.

Another serious problem is the potential for firescaused by short circuits in flooded systems.

Raising electrical system components helps you to havean undamaged, operating electrical system after aflood will help you clean up, make repairs, and returnto your property with fewer delays.


7/23

As shown in the figure, allcomponents of the electrical

system, including the wiring,should be raised at least 1foot above the 100-yearflood level.

BENEFITS OF UTILIZING THISMITIGATION STRATEGY

Helps to prevent damage toelectrical system

components, resulting infaster cleanup and repairs

Helps to prevent fires


8/23

4. Resistant Building & Foundation


9/23

If components such as medical devices, switches and outletare at low level, they must be designed to prevent damagefrom flooding.

Flood Resistant

making a building resistant to flood damage

Taking building out of contact with flood water Making building resistant to any potential damage

Requires structural and non-structural components to bedurable, resistant to flood forces, and resistant todeterioration caused by inundation with floodwater.

may involve waterproof enclosures, barriers, protectivecoatings, or other techniques to protect vulnerablecomponents


10/23

5. Install Sewer Backflow Valves


11/23

Flooding can cause sewage from sanitary sewer lines

to back up through drain pipes.

These backups not only cause damage that is difficult

to repair but also create health hazards.

Solution: install backflow valves, which are designed to

block drain pipes temporarily and prevent return flow.


12/23

Among the simpler valves are flap or

check valves, which open to allow flowout of the structure but close when the

flow reverses.

These check valves operate automatically

but do not provide as strong a seal as a

gate valve.


13/23

BENEFITS OF UTILIZING THIS MITIGATION

STRATEGY

Helps to prevent damage to a structure Helps

to protect the health and safety of the

structures Occupants.

6. Dry Flood Proofing

sealing the structure to prevent flood waters from entering

involves constructing flood barriers


15/23

Figure (a)

flood water, including water that has saturated the soilunder the building, pushes in on walls and up on floors.

The upward force on floors is called buoyancy.

Figure (b) Water that has saturated the soil poses a special hazard for

basement walls.

Hydrostatic pressure increases with the depth of the water,

the pressure on basement walls is greater than thepressure on the walls of the upper floor

This pressure is made even greater by the weight of thesaturated soil that surrounds the basement.


16/23

The walls of buildings built according to standard

construction practice are not designed to resist this

pressure.

Once the pressure exceeds the strength of the walls

(including basement walls), it can push them in,

cause extensive structural damage, and possiblycause the building to collapse.


17/23

7. Add Waterproof Veneer to Exterior Wall


18/23

New brick veneer

Act as the first boundaries in preventing thewater to flow through the first membrane

Existing batt insulation

To prevent moisture damage to the inner wall

during flood occur.

Waterproof membrane

Act as the preventing measure from any kind of

situation during flood, so that the closed-cellfoam insulation is not being exposed to the highamount of water penetration.


19/23

Closed-cell foam insulation

Closed cell foam insulation is washable so that

will prevent from the growing of bacteria andfungi during humidity when the flood occur.

Extended footing

To prevent the water from ground levels to reachclosed-cell foam insulation

Existing foundation and footing

Act as the extra preventing measure to protectthe floor of the building.


20/23

8. Make an emergency plan

As an initial preparation before flood occurs.

Make sure that all the staffs attend training onemergencies involving flood situation.

Making an emergency plan template that include:

The coordinator to lead an operation to secure and reduce

the damage of existing medical equipment. Identify all types of medical equipment in the hospital

including their numbers and position in the hospital.

prepare a path to shift all medical devices to a safe placeduring flood.


21/23

9. Health Information Protection & Transfer

Health records should be kept electronically

Share electronic health and medical informationacross states before flood occurs

Health Information Technology (HIT)The use of computer hardware and software to

store, share & retrieve patient information

Health Information Exchange (HIE)

The movement of health informationelectronically across multiple organization


22/23

Challenge: Inability to communicate, share and

transmit health info during flood

Solution: Ensure telecommunication connectivity

during flood for HIE

Allowing emergency responders to use the

government Emergency Telecommunications Service

when regular telecommunications are disrupted

Wireless Priority Service giving priority cellular

access


23/23

Conclusion

Hazards following flood:

1. Electrical Hazard

2. Structural Hazard

3. Contamination Hazard

4. Hazardous Materials

5. Explosion Hazard

Research on the possibility of flood occurrence of

the hospital area.

Prevention and measures to reduce damages.
