Insights

Intraoperative testing during cochlear implantation (CI) adds operating room time and may increase hospital charges. Selective use of evoked compound action potential (ECAP) and electrical impedance (EI) testing can reduce costs for CI patients.

Area of Science:

  • Otolaryngology
  • Medical Economics

Background:

  • Cochlear implantation (CI) is a complex surgical procedure.
  • Intraoperative testing is often performed to assess device function.
  • The economic impact of intraoperative testing on hospital charges is not well-defined.

Purpose of the Study:

  • To measure the time spent on intraoperative testing during CI.
  • To determine the impact of this testing on hospital charges.

Main Methods:

  • Prospective study in a tertiary referral hospital.
  • Recorded time for intraoperative testing (evoked compound action potentials/electrical impedances) in 22 pediatric CI cases.
  • Analyzed billing data to assess impact on hospital charges.

Main Results:

  • Average testing time was 6.7 minutes (range: 2-26 minutes).
  • No correlation found between testing time and preoperative CT findings, audiologist, or electrode type.
  • 23% of cases incurred higher charges due to intraoperative testing.

Conclusions:

  • Intraoperative testing increases operating room time and hospital charges for CI patients.
  • Selective use of testing may reduce costs for patients and hospitals.
  • This has implications for cost-conscious healthcare environments.

Lattice Centering and Coordination Number

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.

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Measurement: Standard Units03:38

Measurement: Standard Units

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Measurement: Derived Units

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Center of Gravity00:58

Center of Gravity

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

Center of Gravity

The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...
