& in hospital• Information centre to render advice on telephone or
in person on simple medical queries• Capacity & capability to provide effective
management during disaster situations
Functions…..
• Liaison with courts & police in a medico-legal cases
• Provision of ambulance services• Act as information & communication center
especially during disasters• To provide education, training & research
Types of A & E Departments
• Type I : Large hospital with all specialists available round the clock
• Type II : Emergency room physician available round the clock where specialists on call
• Type III : Standby emergency facilities with physician & nurse on call
• Type IV : Referral emergency service where only nurse is available. First aid & refer
Planning
• Location– Should be loc on the ground floor– Direct access from the main road– Separate approach, other than OPD with a
spacious parking area– Loc adjacent to OPD– Well lighted & boldly sign posted both for day &
night– A helipad is required for major trauma centres,
hilly or unapproachable areas
Interrelationship
• Close relationship with:– OT– ICU– Blood bank– Laboratory– OPD– Mortuary– Some authorities recommend a close relationship with
CCU as well– Many sub-depts like OT, Diagnostics etc may be required
in the dept itself
Work & Traffic flow
Lay out
• Core type– Treatment spaces situated around a central point
in which emergency dept personnel work– Ideally, there should be a corridor outside the
treatment area through which the patients enter the cubicles
– Support rooms( plaster cast room, obstetrics & gynae room) are along the periphery of the corridor
– Greatest freedom of movements for emergency dept personnel
Core Design
Lay out….
• Arena type– Essentially a core plan design without the
periphery corridor– Provides a good view of all the cubicles from the
nursing & physician work areas– Less fatigue as distances are less– Best suited for emergency depts that are smaller
in size
Arena design
Lay out
• Corridor type–Many variants possible depending on the
size of the dept–Desirable plan for large emergency depts– Separate space is provided for each
specialty
