Economy Flashcards
- Measures of health status traditionally have been based on mortality data. The principal reason this is no longer satisfactory is that:
The population is older and more subjective to chronic illness than in the past.
- After the onset of blindness resulting from diabetic retinopathy, a 54-year-old man seems depressed. When you question him regarding the quality of life, he dejectedly tells you that 10 years “like this” is not worth 1 year of good health. Before going blind, the patient’s physician estimated that his life expectancy was 74 years. Which of the following statements is true for the patient?
Each year of his life contributes less than 0.1 QALY.
- In which of the following ways is health promotion distinguished from disease prevention?
Only health promotion involves materials and methods that are generally nonmedical.
- Which of the following is an example of secondary prevention?
Cholesterol reduction in a patient with asymptomatic coronary artery disease
- In chemistry, Le Chatlier’s principle states that – when a system at equilibrium is stressed, the system reacts to counterbalance the stress and reestablishes equilibrium. Applied to individual health, this principal might be adapted to state that when a healthy individual experiences distress. Successful adaptation to harmful stressors results in restoration of wellness. Unsuccessful adaptation would result in compromised function and would be an indication of:
Overwhelming allostatic load
- Years of potential life lost (YPLL) is a measure of health status that:
Can always be calculated using life expectancy and age of death only.
- You are interested in helping a 45-year-old perimenopausal woman avoid osteoporosis. The patient is motivate but has a fixed income, is personally liable for her medical expenses because of lack of health insurance, and is concerned about the expense. Assume that (1) the cost of preventive medical therapy is fixed at $660 per year, (2) this therapy will prevent the development of a hip fracture in the apatient at age 68 years, (3)The current cost of surgical fixation of the hip fracture is $ 12,000, and (4) the yearly rate of inflation is 4%.
Disregarding any effects of inflation, how much money would the patient spend to prevent a hip fracture at age 68 years if she started medical therapy now?
$15,180
- When inflation is taken into account, what is the cost of surgery to repair a hip fracture in the patient at age 68 years?
($12,000)(1 + 0.04)^23
- When true inflation-adjusted costs are considered, you determine that the total cost of medical therapy would be close to $42,000 over 23 years, whereas surgical fixation would cost about $48,000 in 23 years. Given this information, you decide that medical therapy to prevent hip fracture:
Has a favorable cost-benefit ratio.
- Vaccinating a health care worker against hepatitis B virus.
Specific protection
- Giving isoniazid for 1 year to a 28-year old medical student whose result in the tuberculin skin test using purified protein derivative recently converted from negative to positive.
Secondary prevention
- Performing carotid endartectomy in a patient with transient ischemic attacks.
Tertiary prevention
- Recommending regular physical activity to a patient with no known medical problems.
Health promotion
- Incorporates life expectancy and the perceived impact of disability on the quality of life.
Quality-adjusted life years (QALY)
- The number of years of life remaining expected to be free of serious disease.
Healthy life expectancy
- A measure of mental health, general well-being, self-control and vitality.
General well-being adjustment scale
- The average number of years of disability –free life remaining at a given age.
Life expectancy free of disability
- In the 1950s, Hollingshead and Redlich showed an association between social class and mental illness, with more cases of mental illness found in the lower social classes. This finding:
Indicates that mental illness and social class are correlated; causality is uncertain.
- Which of the following is a relatively minor contributor to individual health?
Health care
- A 63-year-old man has high blood pressure, high cholesterol, and poorly controlled diabetes. His physician is concerned that he is at high risk for a heart attack and counsels him to quit smoking. According to the Health Belief Model, in order for the patient to change his behavior and quit smoking,
Quitting can prevent a heart attack.
- The patient from question 3 considered his physician’s advice and purchased nicotine gum. By the transtheoretical model, the purchase of the gum represents what stage of change.
Preparation
- Mother cows (vacca in Latin) pass protection from disease to their calves through breast mild. Similarly, human mothers can pass protection from disease to their infants through breast milk. Both such transfers of immunity are examples of :
Passive immunity
- A population’s risk of disease unvaccinated is 90%. With vaccine that risk falls to 10%. The vaccine’s effectiveness is thus (0.9 – 0.1)/0.9 = 88.9%. This quantity is equivalent to the:
Relative risk reduction (RRR)
- Which of the following is a valid medical reason not to immunize a child (or an adult)?
Encephalopathy of unknown cause within 7 days of previous vaccination
