### error:

Medication error
* Some medication errors do cause permanent injury and even death.
* account for a significant portion of preventable adverse events.
* are a health issue
  - just one of the problems or challenges associated with the use of medications
  - more common than adverse drug reactions
* are one of the most common types of errors
  - types of preventable adverse events
* occur frequently in hospitals.
* represent only one of the many types of medication related problems.

Omission
* are mistakes
  - neglect
  - situations
* is an error

### error | omission:

Apheresis
* allows a single donor to provide more of the single component needed by a patient.
* is an omission
  - unusual kind of blood donation
  - another treatment for rheumatoid arthritis that removes antibodies from the blood
  - dialysis
  - less invasive than bone marrow harvesting and requires no anesthesia
* is the method used to collect only one part of blood from a donor
  - most efficient way to harvest sufficient numbers of granulocytes for transfusion
  - usually painless and causes minimal discomfort
* takes more time than whole blood donation, but the yield of platelets is much greater.
* treatment that removes antibodies from the blood.

### error | omission:

Ellipsis
* All ellipses have eccentricity less than one.
* Ellipses are a class of mathematical shapes
  - common in physics, astronomy and engineering
  - like circles that have been elongated slightly, and they are also referred to as ovals
  - neon signs of omission and can cause a quotation to look suspect
  - oval-shaped loops
  - simple enough geometric constructs to capture powerful cosmology
  - used often in everyday life as well as in literature
  - can be solid or hollow
  - do have their own generator, but only for efficiency
* Ellipses have conformal conics as caustics, hyperbola for , ellipses for
  - no straight sides
  - three dots, no more, no fewer
  - two perpendicular axes about which the ellipse is symmetric
  - perform two very distinct functions in writing
* Ellipses represent centers of receptive fields
  - specific entity attributes
  - use cases, i.e. actions or units of functionality in a system
* Some ellipses are much flatter than the earth's orbit.
+ List of literary terms, E, Ellipsis
  * Ellipses are used often in everyday life as well as in literature. It is usually used in leaving out or not using words.

Parapraxis
* Parapraxes are full blown psychical phenomenon and always have a meaning and an intention
  - slips of the tongue, now, of course, commonly called Freudian slips
* is an error

Parity error
* are often a signal that something is working incorrectly in the system.
* occur when the serial hardware detects an incorrect parity bit.

Random error
* are errors that affect the precision of a set of measurements
  - which fluctuate from one measurement to the next
  - generally small errors that occur during the process of surveying
* is introduced to mimic the effects of nature on existing lifeforms.
* tend to cancel when individual values are used to determine an average.

Refractive error
* are generally correctable by glasses, contact lenses, or refractive surgery.
* can create distortions.
* cause a disturbance in the way that light rays are focused within the eye.
* is clearly the largest cause of decreased vision in third world countries
  - treated with glasses and patching of the normal eye
* occur when the cornea fails to focus light rays precisely on the retina.
* tend to be inherited, but there is no pattern of inheritance.

Skip
* are gaits.
* is an error
