    • ORGANIZATION OF LAB SERVICES DR.N.C.DAS
    • LAB SERVICES LAB SERVICES CLINICAL LABS Cardiology, Neurology, Respiratory, Nuclear lab PATH LABS Clinical, Micro, Histo, Cyto, Bio-chemistry
    • CHANGING ROLE OF LAB SERVICES
      • Once upon a time the hospital laboratory, was a small, dark, cul-de-sac reeking of chemicals, and located in the bowels of the hospital next to the morgue.
      • The scenario is changing fast its image and emerging as a high-tech, respected member of the hospital team.
      • Medical technologists and technicians no longer huddle over racks of test tubes; instead, they work in brightly-lit, air-conditioned labs.
      • Monitoring and maintaining sophisticated laboratory analyzers capable of running hundreds of patient samples each day.
    • IMPORTANCE OF LAB
      • Laboratory services are essential to health care delivery.
      • The hospital lab offers the convenience of local service, and familiarity with both the outpatient and his physician.
      • Hospital labs depend on their outpatient testing to make up money lost during times of low in-house census
      • They address both preventive and curative activities, i.e. patient diagnosis, and the selection of drugs for treatment.
      • They are also an indispensable tool in the surveillance and control of diseases.
      • Improved disease recognition will improve the accuracy of statistical reporting, and thus effective national health planning.
    • PRINCIPLE OF PLANNING The planning of hospital Lab services depends on following factors:- LAB SERVICES
    • LAB PLANNING
      • Successful laboratory services is one that comes from careful planning and designing to meet current and foreseeable needs of personnel, equipment and spaces).
      • Secondly the type and extent of services to be provided depending on:-
      • 1. OPD services: Central Laboratories
      • 2. Ward Services
      • 3. Emergency Services
        • i) Round the clock services
        • ii) Restricted Emergency Services
        • 4. Type of investigation to be provided
    • KEY ELEMENTS OF PLANNING OF LABORATORY PLANNING INFRASTRUCTURE/ WORK PLACE EQUIPMENTS & FACILITIES MANPOWER
    • PLANNING OF INFRASTRUCTURE 1. Depends on type of services to be provided. 2. Work load and bed strength of the hospital .
      • Traditional ‘closed’ laboratory: The traditional hospital laboratory has discrete sections in hematology, chemistry, microbiology and blood bank generally separated into rooms or sections.
      • Open laboratory: The discrete services are placed in one large room with portable walls that can be adjusted as needed.
      • Core laboratory : Haematology and Chemistry (Chematology).
      • Regional laboratory: Low volume or expensive laboratory services consolidated in to one hospital
      • Reference laboratory: Traditional full service laboratory that handles all types of testing.
      • Point of care : Tests at patients bed side.
      • Stat laboratory: Rapid response lab often located near an emergency department provides critical lab test e.g. haematocrit, blood gases.
      • Limited service: Limited menu of routine and/or specialty services.
    • PLANNING OF INFRASTRUCTURE INFRASTUCTURE SIZE LOCATION ADMN. AREA ENVIRONMENTAL CONSIDERATION AUXILLARY AREA FUNCTIONAL AREA
    • SIZE OF THE LAB.
      • Size depends on the function
      • Generally 1 sq ft/ 20 samples annually.
      • Minimum requirement for each unit are 10 ft x 20 ft
      LOCATION
      • Lab should preferably in ground floor.
      • Easy access to indoor, emergency and OPD.
      • Different sub units may be located at
      • - OPD Unit
      • - Emergency Unit
      • - Small unit attached to ICU and wards
      • - Main Central Unit
      • - Morgue
    • FACILITY DESIGN PROCESS STAGES ACTIVITIES SITUATION ANALYSIS Needs assessment staffing needs/requirements Technologic changes, current and anticipated . Identify team players (architect, laboratory staff. Medical staff interior designer etc.) STRATEGIC PLANNING Activities to be performed ,flow of people and materials storage. Equipment to be used, utilities. Laboratory sectional needs. STRUCTURAL DESIGN Structural design, identify construction materials. Architectural design. Cost System options (plumbing, electricity/heating/ventilations/air conditioning). INTERIOR DESIGN Interior design. Colors, fabric, texture, finish

    • CENTRAL COLLECTION UNIT
      • It is centrally located in OPD.
      • Space required depends on type of collection, work load and drainage minimum
      • capacity of 150-200 patient collection.
      • The various components includes:
