Summary
The demand for endoscopic retrograde cholangiopancreatography (EUS) in the United States is projected to exceed current resources. This study estimates a significant need for EUS procedures annually, highlighting potential capacity shortfalls.
Area of Science:
- Gastroenterology
- Medical Technology Assessment
- Health Services Research
Background:
- Endoscopic ultrasound (EUS) is a standard diagnostic and staging tool for gastrointestinal (GI) malignancies.
- Uncertainty exists regarding the sufficiency of current EUS resources to meet potential demand.
- This study evaluates the hypothetical demand for EUS services in the U.S.
Purpose of the Study:
- To estimate the total number of EUS procedures that would be indicated annually in the United States.
- To assess whether existing EUS resources can meet this projected demand.
- To identify factors for future EUS capacity planning.
Main Methods:
- Retrospective review of EUS cases from 3 expert centers in 1997.
- Extrapolation of trends to national cancer statistics.
- Calculation of hypothetical demand based on GI malignancy incidence, unresectable cases, elderly nonsurgical candidates, and emerging indications.
Main Results:
- A hypothetical annual demand of 79,568 EUS cases was calculated for the U.S.
- Specific indications include esophagus (10,287), stomach (10,666), pancreas (23,069), and rectal (35,546).
- Including "other" indications, the potential annual procedures could reach 89,116, with a conservative estimate of 79,572.
Conclusions:
- Current EUS resources in the U.S. are likely insufficient to meet the projected demand.
- Future planning must consider the number and capacity of endoscopy units performing EUS.
- Implications for EUS training programs in the United States require careful consideration.

01:01Production Efficiency
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).
00:51Energy Budgets and Reproductive Strategies
Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
01:05Estimation of the Physical Quantities
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...
01:29Econometric Views (EViews)
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...
01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
01:29Levels of Use of a GIS
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...
