Drug Reactions--a Major Cause of Death
Adverse drug reactions may cause the deaths of over 100,000 US hospital patients each year, making them a leading cause of death nationwide, according to a report in the Journal of the American Medical Association.
"The incidence of serious and fatal adverse drug reactions (ADRs) in US hospitals was found to be extremely high. " say researchers at the University of Toronto in Ontario, Canada.
They carried on an analysis of 39 ADR-related studies at US hospitals over the past 30 years and defined an ADR as "any harmful, unintended, and undesired effect of a drug which occurs at doses used in humans for prevention, diagnosis, or therapy. "
An average 6.7% of all hospitalized patients experience an ADR every year, according to the researchers. They estimate that " In 1994, overall 2,216,000 hospitalized patients had serious ADRs, and 106,000 had fatal ADRs. " This means that ADRs may rank as the fourth single largest cause of death in America.
And these incidence figures are probably conservative, the researchers add, since their ADR, definition did not include outcomes linked to problems in drug administration, overdoses, drug abuse, and therapeutic failures.
The control of ADRs also means spending more money. One US study estimated the overall cost of treating ADRs at up to $ 4 billion per year.
Dr. David Bates of Brigham and Women's Hospital in Boston, Massachusetts, believes that healthcare workers need to pay more attention to the problem, especially since many ADRs are easily preventable. "When a patient develops an allergy or sensitivity, it is often not recorded, " Bates notes, "and patients receive drugs to which they have known allergies or sensitivities with disturbing frequency. " He believes computerized surveillance systems--still works-in-progress at many of the nation's hospitals--should help cut down the frequency of these types of errors.
Researchers at the University of Toronto believe that ______.

Characteristics of a Good Speaker
In speaking, as in most human activities, success depends upon a combination of factors. A good speaker, according to most authorities both ancient and modern, must have integrity, knowledge, self-confidence, and skill.
Integrity
Some nineteen hundred years ago the Roman teacher Quintilian insisted that a good speaker must first of all be a good man. Listeners, Quintilian maintained, cannot separate what is said from the person who says it: they are influenced by their impression of the speaker as well as by the arguments he presents.
If a person is habitually unreliable, speech training may give him skills, but it cannot make him effective. His actions will contradict his words: he cannot convincingly urge honesty in government if he himself cheats in school or business; his appeal for an open mind in others will go unheeded if he himself is bigoted (偏执的). Even a speaker's choice of words and arguments betrays his character, for he may habitually appear to dodge issues rather than face them or to say what is popular rather than say what is true or just. A speaker of poor character may succeed for a time, but in the long run he will be found out and his appeals will be discounted.
Knowledge
Acquiring the knowledge necessary to become a good speaker is a lifelong and cumulative (累积的) task. Through thoughtful reading, listening, and observing, you can gain increased intellectual depth and maturity. While the first speeches you deliver may be on relatively simple subjects and may be based in part on personal experiences, they should present worthwhile ideas and considered convictions. Soon you will want to reach out beyond immediate and familiar topics--to learn and to speak about subjects in new fields. The more you learn about many subjects, the more effective your speaking will become. Moreover, what you say on any particular topic will reflect the knowledge and understanding of the educated person.
Confidence
A self-confident speaker has an erect but comfortable posture; natural, easy gestures; direct eye contact with his audience; and earnestness and energy in his voice. Moreover, he adapts his information and arguments to the attitudes of his listeners.
Many factors help determine the amount of nervousness a speaker may feel--including the amount of sleep he had the night before his speech, But the experience of many generations of speakers has shown that, in addition to preparing carefully, you can do much to increase your poise and self-control by following three simple rules:
1. Speak as often as you can. The first time a person drives a car or flies an airplane alone, he is likely to be tense and unsure of himself, but with each additional experience his confidence grows. In the same way, each successful speech you make will strengthen your self-assurance. Welcome every opportunity to speak, both in your classes and to groups in the community. Select subjects that you know a good deal about and that you are deeply interested in. Prepare your talks carefully. You will find that after a time speaking becomes a pleasant rather than a painful experience.
2. Remember that some nervous tension is both natural and good for you. Even in the deepest sleep our muscles are never completely relaxed. When we are awake our "muscle tension" is higher, and it increases still more when the mind or body is called upon for
When you are having a old ______.
