List of metropolitan areas by population. One concept which measures the world's largest cities is that of the metropolitan area, which is based on the concept of a labor market area and is typically defined as an employment core (an area with a high density of available jobs) and the surrounding areas that have strong commuting ties to the core.
Average Costs. In treatment year 1, the average costs per patient diagnosed with PTSD ($8,300), TBI ($11,700), or both ($13,800) were much higher than the average costs for those with neither PTSD nor TBI ($2,400) (see Table 2 and Figure 3 on page 20).
Pressure ulcer treatment costs range from $2000 to $70,000 per wound, with the average hospital's total costs being between $400,000 and $700,000 annually. A preventable problem: Pressure ulcers can be prevented through use of relatively simple measures. In fact, national initiatives, such as the Joint Commission's 2009 National Patient Safety Goal #14,focus on preventing health care-associated pressure ulcers through use of established guidelines.
