Demographic Trends in Healthcare
 According to a 2004 Report of Social Security Trustees: 
 – In 1950, there were 16 workers to support every 1 
   beneficiary of Social Security.
 – Today, there are only 3.3 workers supporting every 
   Social Security beneficiary.
 – And, by the time our youngest workers turn 65, there will 
   be only 2 workers supporting each beneficiary.


 According to a report prepared by CMS:
  – spending for personal health care per senior citizen was 
    almost 400 percent greater than for those under 65.  
  – According to this study, over 1/3 of these senior's 
    healthcare spending is on hospital care.

                        Definitions
    Material Handling is the movement, storage, control & protection 
of materials, goods and products throughout the process of 
manufacturing, distribution, consumption & disposal.
 
    Logistics: The problems and methods of obtaining, transporting, 
distributing, maintaining and replacing material and personnel.
 
    Automation is the application of computer-based system to 
improve productivity and quality of performance. 

§  Automated Storage & Retrieval System (ASRS): A system for 
automatically storing and retrieving loads from defined storage 
locations under computer control. 

    Automated Transport System (ATS): A computer controlled 
system for automatically moving materials between two or more 
locations.

     Automated Storage & Retrieval 
           System (ASRS)
Systems for automatically storing and retrieving loads from 
defined storage locations under computer control.

     Materials are stored and protected securely inside the 
     storage units
     Decreased inventory levels possible
      through centralized storage & control

     Abstract Submitted & Approved
Automated systems operate 24/7, don't take breaks, call in sick , file 
grievances or leave for other jobs. Finding people for mundane or 
difficult tasks will get harder. Learn how automation streamlines the 
flow of materials in the hospital, fix future costs, reduces labor and 
delivery time and frees resources for improving patient care.
Learn about many kinds of automated material handling and storage 
systems used in hospitals today. Learn how the system choice is 
influenced by the size and time sensitivity. Materials moved and 
stored in these automated systems include pharmacy meds, lab
samples, central supplies, linens, trash, bio hazardous wastes,
nuclear medicine, SPD, patient food and more.
This overviews include weight capacities, speeds, throughput,
operator and facility interfaces for pneumatic tube systems, robots,
track vehicle systems, vertical conveyors, automatic guided vehicle
systems, horizontal and vertical carousels, automated storage and
retrieval systems, box pickers, and pharmacy automation solutions.
