Hospital: • Hospitals/Healthcare centres are the first contact point between members of the Public and health workers. • Medical institutions provide treatment for and care of patients with a wide range of chronic acute conditions. • Construction must satisfy the needs of a number of functions: accommodation, research, teaching, medical activity, storage and administration. • Most important to remember wihle designing is that you are designing for physically unfit people. There are several that should be considered in the design of a primary healthcare building. These include –  Location of the building: should be convenient in relation to the people it serves.  Circulation: Entrance and circulation within the building must consider wheelchair users, parents with small children and people with disabilities, etc.  Effective zoning is required: public zone, clinical zone and staff zone.  Privacy and confidentiality are important, especially at the reception desk and clinical rooms during consultations and treatments.  Security and supervision in the premises will be necessary, including staff protection against personal assault and safeguarded against theft and vandalism.  For running costs, efficient staffing, energy efficiency, long-life and low-maintenance approache should be adopted.  Flexibility and growth should be catered for: flexibility in use of some, and potential for future extension of the building.

PLANNING CONCEPTION Location: • Site should offer sufficient space for self contained residential areas and hospital departments. • Should be a quiet location with no possibility of future intrusive developmnet. • Adequate area should be there for future expansion. • Should be away from dust, noise and pollution.

Orientation: • Treatment and operating rooms are preferred between north-west and north-east. • For nursing ward facades, south and south-east is favourable due to: Pleasant morning sun Minimal heat build up Little requirement for sun shading Mild in the evenings • East and west facing rooms have comparatively deeper sun penetrations, though less winter sun. • The orientation of wards in hospitals with short average stay is not so important. • Some departments might require rooms on the north side so that patients are not subjectes to direct sunlight.

Forms of building: • Spine form with branching sections. • Radial arrangement, i.e. circulation will be radially outward from the centre of the core. • Any form that goes with the proper connectivity of all the units.

Effective arrangements: • Top floor: Helipad, ac plant room, nursing school, laboratories. • 2nd/3rd floor: Wards can be provided. • 1st floor: Central sterilisation unit, surgical area, intensive care, maternity, children’s hospital. • Ground floor: Entrance, radiology, medical services, ambulance, entrance for bed-ridden patients, emergency ward, information centre, administration, cafeteria. • Basement: Stores, physiotherapy, kitchen, heating and ventilation plant room, radio therapy, linear accelerator. • Sub-basement: Under ground garage, electricity supply.

FACILITIES AND SPACE REQUIREMENTS – Facilities in the emergency department can be considered broadly under two categories: Administrative and public areas  Clinical facilities

Administrative and Public Areas: • Reception-control: For observation and control of access to the treatment area, public waiting area, and pedestrian and ambulance entrance area. Should be equipped with a communication system including intercommunication. • Waiting patients and their relatives should be better shielded from what is going on in the treatment area. • Space for stretchers and wheelchairs adjacent to the entrance but out of the stream of traffic. • Stretchers should be provided with wheel locks. • Waiting area should be separated from the working or treatment area and should be provided with toilet facilities, water coolers, or drinking fountains, public telephones, STD and ISD call facilities and vending machines if possible. • Space/room for security staff, police, ambulance driver and attendant. • Office for the night adminnistrator/night supervisor – can be off site but not too far away. • Coffee snack bar in close vicinity. Clinical Facilities: Four major functional areas can be identified. These are • Trauma care area where the severely surgical cases are handled. • Medical examining area. • Splintage and casting area for orthopaedic cases. • Observation beds for patients who need to be kept under observation for neurological and other medical reasons.

Facilities Required: • Trauma rooms for emergency trauma procedure or where the severely injured surgical cases are handled. Resuscitation and life support equipment and drugs, medical gas outlets, examination table, examination lights, X-ray film illuminators, cabinets and supply shelves. For orthopaedic and cast work, it is necessary to have closed storage space for splints and other orthopaedic supplies, a plaster sink, traction hooks, etc. • Examination/treatment rooms with examination tables, examination lights, work counters, cabinets, wash basins, X-ray film illuminators, medication storage facilities and medical gas outlets. • Scrub stations conveniently located to each trauma and orthopaedic room. • Additional adjustable space for triage, treatment, observation, etc. in the event of disaster handling. • Staff work area and charting space with counters, cabinets, medication storage facilities, dictating facilities, etc. • Storage space for equipment such as portable X-ray and “crash carts” (cardio-pulmonary resuscitation emergency carts) which should be easily accessible. • Separate soiled and clean utility rooms. • public toilets and janitor’s closet. • Rooms for duty/on-call doctors, separate for men and women, with sleeping accommodation, shower and toilet facilities. • Locked cabinets, etc. for staff’s personal effects.

OTHER CONSIDERATIONS – Triage Area: The emergency department has an active role to play in situations when several emergency cases arrive in the hospital simultaneously, for example, victims of bus or train accident, major fire or other disaster. • The emergency staff are trained to recognize the nature and relative severity of a patient’s condition. In what is called the “triage area”, patients are rapidly sorted sent to appropriate treatment areas. • For example, hyper acute(life threatening) cases are sent to the emergency room, serious casualties are sent to surgery area, ambulatory care(non-life threatening) cases to outpatient department, waiting room or observation area, the emotionally disturbed cases to the chapel or meditation room, and the dead on arrival to the morgue. • A triage sorting system establishes priorities for treatment of critical patients. Priorities are based on the degree to which the patient’s life is threatened. Typically, patients are classified as follows: Emergency: Patient requires immediate medical attention; life, limb or sight is threatened.  Urgent: Patient requires medical attention within a reasonable time and will be in danger if not attended. Non-emergency: Disorder is minor, not acute and can wait.

CLINICAL LABORATORIES: Purpose: Primary function is to perform tests in the six main fields of bacteriology, biochemistry, histology, serology, haemotology and cytology to assist medical staff in making or confirming diagnoses and in the treatment and prevention of disease.

Location: Should be conveniently located on the ground floor to serve the outpatient, emergency, and admitting departments. It should also be close to or easily accessible to surgery, intensive care, radiology and obstetrics.
