Surveys

17.0K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Introduction to Surveying, Plane Surveying and Geodetic Surveys

1.1K
Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Errors and Mistakes in Surveying01:19

Errors and Mistakes in Surveying

738
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

Types of Surveys01:27

Types of Surveys

372
Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

Survey Safety01:28

Survey Safety

418
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Lattice Centering and Coordination Number

12.2K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Summary
This summary is machine-generated.

Most endoscopy centers adopted enhanced duodenoscope reprocessing after MDRO outbreaks, but practices vary widely. Duodenoscope redesign and effective reprocessing are top priorities for providers.

Area of Science:

  • Infectious Diseases
  • Medical Device Reprocessing
  • Gastroenterology

Background:

  • Recent outbreaks of multidrug-resistant organism (MDRO) infections linked to duodenoscopes prompted FDA recommendations for enhanced reprocessing.
  • The adoption of these enhanced reprocessing measures and provider perspectives on priorities were largely unknown.

Purpose of the Study:

  • To assess current institutional practices and provider opinions on duodenoscope reprocessing in US endoscopy units.
  • To identify variations in the implementation of enhanced reprocessing techniques and gauge future reprocessing priorities.

Main Methods:

  • A survey was distributed to physicians, nurse managers, nurses, and infection control staff at endoscopy units performing ERCP in the United States.
  • The survey collected data on current reprocessing practices, implementation of FDA-recommended measures, and opinions on reprocessing solutions.

Main Results:

  • 89.6% of 249 participating institutions implemented at least one enhanced reprocessing method.
  • Commonly adopted methods included repeat high-level disinfection (63%), surveillance culturing (53%), and liquid chemical sterilization (35%).
  • 50% of respondents, including 58.6% of physicians, favored duodenoscope redesign as the optimal long-term solution, with efficacy being the most critical factor (55.1%).

Conclusions:

  • While most centers implemented enhanced duodenoscope reprocessing, significant practice variations exist.
  • Duodenoscope redesign and maximizing reprocessing efficacy are identified as key long-term goals.
  • There is a need for improved adherence to forced-air drying protocols during duodenoscope reprocessing.
