Answer:
a. dates back to seventeenth century England
Explanation:
Health care data refers to the different records of events obtained in the hospitals. The recording and keeping of these data dates back to seventeenth century England. The events usually include mortality,natality,life expectancy information. Data of mortality caused by different types of diagnosed ailments are usually taken note of. This helps to ensure the proper planning in the health sector. The diseases which requires urgency as a result of its high prevalence are also taken note of for thorough handling and treatments.
Answer:
Explanation:
ED triage: Used daily to prioritize patient assessment and treatment in the emergency department during routine functioning. Priority is given to those most in need. Resources are not rationed. Inpatient triage: Applied day-to-day in a variety of medical settings, such as the ICU, medical imaging, surgery, and outpatient areas, to allocate scarce resources. Priority is given to those most in need based upon medical criteria. Resources are rarely rationed. Incident triage: Used in multiple casualty incidents such as bus accidents, fires, or airline accidents to prioritize the evacuation and treatment of patients. These events place significant stress on local resources but do not overwhelm them. Resources are rarely rationed, and most patients receive maximal treatment. Military triage: Used on the battlefield, modern military triage protocols most reflect the original concept of triage and include many of the same principles. Resources are rationed when their supply is threatened. Disaster triage: Used in mass casualty incidents that overwhelm local and regional healthcare systems. Disaster triage protocols both prioritize salvageable patients for treatment and ration resources to ensure the greatest good for the greatest number.
Answer:
Common causes of blindness are diabetic neuropathy, glaucoma and cataracts.
Explanation:
Blindness refers to the complete lack of functional vision.It occurs when an inadequate amount of light hits the retina, or the information has not been delivered to the brain correctly.
Complete blindness : characterized by a complete and total loss of vision. Merck Manuals reports that legal blindness is defined as having equal to or worse than a 20/200 visual acuity in the better eye. Having a visual acuity of 20/200 means that someone with normal vision can see an object at 200 feet, and a person with impaired vision can see at a distance no further than 20 feet. Several different diseases can cause complete blindness; some develop later in life and some are present at birth. The leading cause of blindness in the United States is diabetes, according to the National Eye Institute. Diabetes causes diabetic retinopathy, which results in destruction of the retina. Other causes of complete blindness include age-related macular degeneration, which the National Eye Institute calls the most common cause of blindness in adults who are 60 or older; cataracts, which obstructs light from hitting the retina because of opaque patches on a lens; and glaucoma, which causes blindness due to damage to the optic nerve.
Color Blindness
:
People who have color blindness, also called dyschromatopsia, are unable to distinguish certain colors. This type of blindness more commonly affects men than women. Merck Manuals reports that the most common form of color blindness is red-green color blindness, which makes it difficult to distinguish certain shades of red and green. Color blindness is almost always present at birth, and is usually caused by the presence of a defective gene on the X chromosome. The reason that more men are affected by color blindness than women is that women have two X chromosomes; thus, even if they are "carriers" of a bad gene, their other X chromosome usually has a functional gene. Because men have only one X chromosome, the presence of one bad gene is sufficient to cause color blindness. Defective retinal cells result in some forms of color blindness; other forms are caused by defects in the optic nerve.
Night Blindness
:
Night blindness is vision impairment that occurs at night or when light is dim. It does not generally result in a complete lack of vision but significantly impaired vision. People with night blindness often have difficulty driving at night or seeing stars. Several different factors cause night blindness, according to the University of Maryland Medical Center. These factors include cataracts, birth defects, a vitamin A deficiency, or a retinal disease called retinitis pigmentosa
