Health Care System in Canada, The Future and History of Canadian Health care,

Health Care System in Canada, 
network of providers, institutions, and insurers that care for the health of Canadians. In Canada health care is delivered by private institutions—hospitals and physicians—that are not controlled directly by the government. This private delivery system is combined with a publicly financed health insurance system that is paid for by the provincial and federal governments. (In this article, the use of the term “provincial” refers to both provinces and territories, since territories and provinces play the same role in the health care system.) This health insurance system is known as Medicare. Each province has a separate health insurance system funded by provincial government revenues and contributions from the federal government. The federal government provides funding in a lump sum based on the province’s population. Of the total spending on health care in Canada in 1998, provincial expenditures made up 45 percent and federal transfers to the provinces made up 18 percent. Private spending made up 31 percent and accounted for most of the rest. The largest outlays were in these sectors: hospitals, 32 percent; physicians, 14 percent; and drugs, 16 percent.



II  PROVINCIAL SYSTEMS AND THE FEDERAL GOVERNMENT


The Constitution Act of 1867 made the provinces responsible for matters of health policy (see Constitution of Canada). As a result, instead of national health insurance, Canada has ten provincial and three territorial health insurance systems. Although the federal government has a strong presence in the health sector, the provinces are primarily responsible for health care. Each province and territory has its own statute that regulates its health care system. The provincial governments administer health insurance programs and make decisions about funding hospitals and reimbursing physicians. Most provinces fund their health insurance out of general revenues and do not impose a specific health tax on individuals or businesses. Only Alberta and British Columbia levy health care insurance premiums for their public insurance. Health insurance is an expensive operation, and provinces spend from 30 to 35 percent of their total budget on health care.

The federal government contributes to the provincial systems as part of the Canada Health and Social Transfer (CHST), a block grant that includes the federal contributions to health care, higher education, social assistance, and other social services. The federal government also links the provincial health care systems together with a set of principles, commonly referred to as national standards. These standards were articulated in the Canada Health Act, which the Canadian Parliament passed in 1984.

Under that law, provinces must ensure that their health care systems respect five criteria: (1) public administration—the health insurance plans must be administered by a public authority accountable to the provincial government; (2) comprehensive benefits—the plan must cover all medically necessary services prescribed by physicians and provided by hospitals; (3) universality—all legal residents of the province must be covered; (4) portability—residents continue to be covered if they move or travel from one province to another; and (5) accessibility—services must be made available to all residents on equal terms, regardless of income, age, or ability to pay. In the 1980s and 1990s the federal government began to contribute a lower percentage of provincial health insurance funding. In response some critics questioned the extent to which the federal government could continue to expect the provinces to uphold the national standards of the Canada Health Act with less funding.

In addition to setting standards and providing funds for the provincial health systems, the federal government is required by the constitution of Canada to provide health care to military personnel and veterans, members of the Royal Canadian Mounted Police, and inmates of federal prisons. The federal government is also directly responsible for the health needs of aboriginal Canadians living on reserves. The federal government promotes public health through activities such as prenatal nutrition programs and youth antismoking campaigns. It also maintains laboratories for disease control and product safety.

III  HOW THE PUBLIC SYSTEM WORKS

A  Patients


When a legal resident of Canada needs medical care, he or she presents a provincial health card, usually a plastic identification card similar to a credit card, to a physician or hospital. Patients choose their physicians, although a general practitioner may refer them to a specialist. If patients require immediate care without an appointment, they can seek admittance to any hospital emergency room or community health clinic. There, the severity of their medical need determines how long they will wait to see a nurse or doctor. Health care provision in Canada is based on medical need rather than the ability to pay; consequently, there are often waiting lists for some elective procedures, such as cataract surgery; nonemergency surgery, such as hip replacement; and diagnostic services, such as the use of magnetic resonance imaging (MRI). In addition, medical specialists are often less available in rural and remote areas.

B  Physicians
The majority of Canadian doctors provide care in private practice and apply for admitting privileges at one or more nearby hospitals. Most doctors provide care on a fee-for-service basis. In that arrangement the doctor is paid for each service provided to the patient, rather than earning a set salary or a set amount for each person under his or her care. The fee-for-service format is especially common among specialists and doctors who see patients outside of the hospital. The fee-for-service arrangement allows the physician to decide what care to provide independent of the influence of administrators or insurers. The licensed physician is reimbursed for his or her services through a provincial agency that negotiates a fee schedule with the provincial medical association.

Not all doctors are paid by the fee-for-service format; some are paid a fixed wage, either an hourly wage or a salary. Emergency room doctors, for example, are often paid on an hourly basis. Doctors in their residency (early years of specialty training) in teaching hospitals are generally paid on a salaried basis. In Québec, a small number of general practitioners choose salaried positions in community health and social clinics. In most provinces, specialist salaries are capped at a certain level of income.

C  Hospitals
Hospitals in Canada are nonprofit institutions with independent administrative boards; they are not directly operated by the government. However, all hospitals depend on public funds for their operating costs. These funds are provided through the provincial government and are allocated by means of a yearly global budget. The yearly global budget is a set amount of money that the hospital uses to meet the needs of its patients. Each hospital and each province as a whole has a yearly global budget, which is determined by a provincial agency or a regional board. Provinces and individual hospitals must use the global budget to cover all their costs for personnel, equipment, and supplies. Limited global budgets have at times forced provinces to recommend the reduction of available beds, laboratories, or operating rooms and, in some cases, the closure of certain hospitals.

IV  SUPPLEMENTARY HEALTH CARE

With a few exceptions, provincial health plans cover all medically necessary services, so that patients need not pay directly for anything except so-called incidental costs. These incidental costs include items such as a patient’s private hospital room, unless it is specified by a physician, and transportation to the hospital. Provincial health plans also do not cover some nonessential procedures, such as laser surgery for the eye, cosmetic surgery, procedures to reverse sterilization, and, in most provinces, in vitro fertilization. In addition, provinces do not pay for dental services and long-term or special care facilities, such as nursing homes and addiction-recovery centers, with exceptions. Also provinces generally do not cover prescription drugs for patients outside the hospital. Some benefits vary by province: For example, limited chiropractic and optometrist services are covered in Ontario and British Columbia but not in Québec. Although health benefits are portable across provincial boundaries, there is only limited coverage (mainly for emergency care at provincial rates) for Canadians when they travel outside the country.

Canadians have two choices when it comes to paying for these additional services: They can either pay directly for whatever services they use, or they can join a private supplementary insurance plan, usually offered by their employer. Private insurers are not permitted to offer insurance coverage for any service that provincial insurance covers. That restriction is designed to prevent a two-tier system in which people who could afford more expensive private insurance would have greater access to necessary medical services and procedures.

Many provinces subsidize these additional services for the elderly and those who receive social assistance. Several provinces also have government plans that provide insurance coverage for drug costs and that are available to the entire population, but those plans require substantial contributions from the insured. Private spending on health care in Canada (mainly on dental care and prescription drugs) has been increasing steadily, and in 1998 it accounted for 31 percent of total health care spending.

The practice of extra-billing, in which physicians charge patients a higher fee than that covered by provincial insurance, was common in some provinces. The patients then had to pay the difference between the cost of the service and the amount covered by provincial insurance. The federal government effectively abolished this practice in the Canada Health Act, a law that specifically prohibits extra-billing and penalizes any province that allows it. If a province allows extra-billing, the federal government reduces funding to the province by the amount charged in extra-billing.

V  CANADIAN SYSTEM IN COMPARISON

Although health care in Canada is expensive, the country’s expenditures on health care resemble those in other industrialized countries and are considerably less than in the United States. In 1998 Canada spent C$81.8 billion dollars or C$2,700 per person on health care, representing 9.1 percent of Canada’s gross domestic product (GDP). In contrast, health care expenditures in the United States in the same year totaled 13.5 percent of the U.S. GDP, representing approximately C$5,700 per person. In Canada, about 69 percent of total health expenditures are publicly funded, whereas in the United States 45 percent of health expenditures are funded by the government.

Despite these differences in spending, the number of hospital beds per person in Canada is comparable to the United States (1 for every 244 people in Canada, and 1 for every 826 people in the United States). There is 1 physician for every 476 Canadians (compared to 1 for every 253 people in the United States). Canadian physicians are fairly evenly split between general practitioners and specialists. Hospitals in Canada are as well-equipped to deliver technologically advanced medical procedures as hospitals in other industrialized countries. However, the cost constraints of the Canadian system have made the use of certain expensive diagnostic equipment, such as MRIs, considerably less widespread than in the United States.

There is some debate among economists about the role of national health insurance in controlling health care costs, but it is evident that the Canadian health care sector, because of the government’s involvement, spends considerably less on health care than the United States. There are numerous reasons for the cost difference, but the major factors include the lower administrative costs associated with single-payer insurance, the yearly spending caps set by global hospital budgets, and the negotiation of uniform billing fees with provincial physician associations.

VI  HISTORY


Canada’s system was created through two major innovations. The first innovation was government-funded insurance to cover hospital costs. The second initiative was government-funded insurance to pay for medical services outside of hospitals.

A  Provincial and Federal Initiatives


T. C. Douglas From 1944 to 1961, T. C. Douglas was premier of Saskatchewan, in a government led by the socialist Co-operative Commonwealth Federation. During his tenure, the province introduced a public hospital insurance plan that became the foundation for Canada’s national health insurance system.Archive Photos/Express Newspapers 

Until the 1940s, the government was not very involved in health care. It mostly focused on efforts to improve public health, such as disease control and food and drug regulation. In addition, local governments provided charitable hospitals and medical care for indigent people. Canadians paid for health care either directly out of their pockets or through private insurance.

The first real initiatives for developing public health insurance on a wide scale originated in the provinces. In 1947 the Saskatchewan government, led by the Co-operative Commonwealth Federation, a social democratic party, inaugurated the first hospital insurance plan in North America. The plan used public funds to cover the costs of hospital services. The success of this plan and similar plans in other provinces convinced the federal government to pass the Hospital Insurance and Diagnostic Services Act in 1957. This legislation allowed the federal government to share in the cost of provincial hospital insurance plans. By 1961 every province in Canada had set up a hospital insurance plan.

In 1962 the Saskatchewan government introduced a further innovation: a medical insurance program that used public funds to reimburse doctors for the services they provided to patients outside of hospitals. This again proved to be a successful model. In the Medical Care Insurance Act of 1966, the federal government agreed to share provincial health costs for medical care outside of hospitals. By 1971 every province had a medical insurance plan in operation, and Canada’s health insurance system was fully in place.

In 1984 the federal government combined the 1957 and 1966 laws into the Canada Health Act. This legislation reinforced the underlying principles of the previous health insurance programs, including public administration, comprehensive benefits, universality, and portability. In addition the new law emphasized a fifth principle, equal access, which was designed to prohibit practices such as extra-billing that presented potential financial hardship for some patients.

Federal financial support for health care has varied over time. Prior to 1977 the federal government paid an agreed-upon percentage of provincial medical costs. In 1977 the Established Programs Financing Act replaced this system with a single payment for health care, known as a federal block transfer payment; this new payment was based on provincial population. At various times in the 1980s and early 1990s the federal government froze or reduced those payments as part of a movement to contain health care costs and reduce federal spending in general. Beginning in 1996 federal funding for provincial health systems was combined into a super-grant, the Canada Health and Social Transfer (CHST). The CHST combined federal contributions to health care, higher education, social assistance, and other social services into one lump sum. In the CHST, the federal government provided fewer funds for health care. However, in the 1999 budget the federal government renewed its commitment to health funding and injected new money into the health care sector.

As federal health care contributions declined in the 1980s and 1990s, provincial governments came under pressure to control health care costs. Many provinces attempted to make health care services more efficient by combining or closing hospitals. Some, like Québec, attempted to shift the emphasis of health care delivery to preventative and community care. Most provinces also implemented controls on physicians, such as salary caps for specialists. Governments have also attempted to control demand by extending the waiting lists for certain surgical procedures or discontinuing coverage of some services that are not medically necessary.

B  Attitudes Toward the System

Physicians have displayed an ambivalent attitude toward public health insurance in Canada. On the one hand, government involvement guaranteed universal coverage and did away with the problem of collecting payments from patients and insurers. On the other hand, government involvement necessarily meant some regulation of the profession, including the fees that doctors charge for their services. Some provincial medical associations resisted the introduction of public medical insurance because of this regulation. In Saskatchewan in 1962 and Québec in 1970, physicians went on strike to protest the introduction of government-funded medical insurance.

A consensus eventually emerged. Doctors agreed to respect the fees negotiated with provincial governments in return for the freedom to practice medicine on a fee-for-service basis. This consensus was threatened when some physicians began to charge higher fees than those covered by provincial insurance by extra-billing. The federal ban on extra-billing in the Canada Health Act in 1984 led most provinces to prohibit the practice. In Ontario, where extra-billing was most widespread, the ban prevailed only after a bitter strike by doctors in 1986.

Public opinion polls commissioned by the National Forum on Health in 1994 found that Canadians were profoundly attached to equity and universality in health care. Other polls in the late 1990s showed negative reactions to expenditure cuts and efficiency measures in hospitals. The public saw these cuts as compromising the quality of and access to health care. This perception, along with examples of overcrowding at certain emergency rooms, led to a public backlash against the cuts. In many provinces, as well as at the federal level, politicians became sensitive to public discontent and injected more funds into the health care sector.

Whether demand for expensive health services can be controlled by deterrents such as waiting lists, or whether such controls will lead to greater desire for private medicine remains to be resolved. Canada is one of the very few public health care systems that does not allow some measure of partial payment by patients, such as co-payments, deductibles, or user fees, for services primarily paid for by insurance. Canada is also one of a dwindling number of countries that has not experimented with two-tier medical delivery, in which private health insurance is allowed to cover the same services as public insurance.

The Canadian health care system is at an important and potentially controversial crossroads. On the cautionary side, there seems to be a growing unease about whether the system can be sustained. Can a system that essentially shuts out the private market for health services in an era in which demand for health care is increasing at a remarkable pace survive? On a more positive note, the Canadian health care system is regarded as among the most effective—and popular—of any industrialized country. The Canadian system continues to combine the best features of any successful health care system and offers high-quality, comprehensive care for all citizens at reasonable cost.

Wolfgang Mozart Biography - Facts, Birthday and Life Story

Wolfgang Mozart Biography - Facts, Birthday and Life StoryMozart, Wolfgang Amadeus (1756-1791), Austrian composer, who is considered one of the most brilliant

As a child prodigy Mozart toured Europe and became widely regarded as a miracle of nature because of his musical gifts as a performer of piano, harpsichord, and organ and as a composer of instrumental and vocal music. His mature masterpieces begin with the Piano Concerto No. 9 in E-flat Major (Jeunehomme, 1777), one of about a dozen outstanding concertos he wrote for piano. Also successful as an opera composer, Mozart wrote three exceptional Italian operas to texts by Italian librettist Lorenzo da Ponte: Le Nozze di Figaro (The Marriage of Figaro, 1786), Don Giovanni (1787), and Così fan tutte (All Women Do So, 1790). They were followed in 1791 by his supreme German opera, Die Zauberflöte (The Magic Flute).

Mozart’s works were catalogued chronologically by Austrian music bibliographer Ludwig von Köchel, who published his catalog in 1862. The numbers he assigned, which are called Köchel numbers and are preceded by the initial K, remain the standard way of referring to works by Mozart. The Jeunehomme Concerto, for example, is K. 271.

II  LIFE
and versatile composers ever. He worked in all musical genres of his era, wrote inspired works in each genre, and produced an extraordinary number of compositions, especially considering his short life. By the time Mozart died at age 35, he had completed 41 symphonies, 27 piano concertos, 23 string quartets, 17 piano sonatas, 7 major operas, and numerous works for voice and other instruments.

Mozart was born in Salzburg. From his father, violinist and composer Leopold Mozart, he received his early musical training. By age six he had become an accomplished performer on the clavier, violin, and organ and was highly skilled in sight-reading and musical improvisation. In 1762 Leopold took his six-year-old son on his first concert tour through the courts of Europe. The young Mozart absorbed the musical styles of the time through travel to Austria’s capital, Vienna; the German cities of Munich and Mannheim; Paris, France; London, England; and various centers in Italy. From 1762 to 1766, while he was often touring, he composed several symphonies, a few sacred works, and a number of sonatas for keyboard and violin.

In London in 1764 Mozart met then-popular German composer Johann Christian Bach, son of Johann Sebastian Bach. The eight-year-old Mozart played four-hand piano sonatas with Bach while sitting on the composer’s lap. The symphonies of the younger Bach and of Carl Friedrich Abel, another German composer living in London, offered models for Mozart’s first symphonies (K. 16 and K. 19), written in 1764 and 1765 when he was eight and nine years old. In 1767, at age 11, Mozart transformed piano sonatas by various composers into his first four piano concertos through the addition of interludes and episodes for orchestra. He intended these works (K. 37, K. 39, K. 40, and K. 41) for his own performance. In 1768 he composed his first opera buffa (comic opera), La finta semplice (The Simple Pretense), and his first German operetta, Bastien und Bastienne. The following year La finta semplice was performed at the palace of the Salzburg archbishop, who appointed Mozart his concertmaster.

From 1769 to 1773, Mozart made three extended journeys to Italy with his father, during which he was remarkably productive and wrote not only symphonies and operas but also string quartets and several sacred works. In Milan he was commissioned to write an opera seria—that is, a serious opera in Italian on a heroic subject. The opera, Mitridati, rè di Ponto (Mithridates, King of Pontus), was produced in 1770 in Milan under Mozart’s direction with success. Also that year the pope made Mozart a knight of the Order of the Golden Spur.

III  MUSIC

Mozart’s music can be divided into periods of stylistic assimilation and stylistic innovation. From childhood he showed skill at imitating virtually any type of music, including the sacred style of church music and the so-called galant (courtly) idiom. The elegant though often superficial galant style dominated much instrumental music of the 1760s and 1770s. Mozart’s mastery often demonstrates itself in an ability to expand and deepen the stylistic possibilities of the time. The manner in which he extended the character and form of the concerto, for instance, owes much to his experience in writing operatic arias.

High Blood Pressure (Hypertension) and Causes of High Blood Pressure: Weight, Diet, Age, and More

Blood Pressure,
High Blood Pressure (Hypertension) and Causes of High Blood Pressure: Weight, Diet, Age, and More pressure of circulating blood against the walls of the arteries (blood vessels that carry blood from the heart to the rest of the body). Blood pressure is an important indicator of the health of the circulatory system. Any condition that dilates or contracts the arteries or affects their elasticity, or any disease of the heart that interferes with its pumping power, affects blood pressure.

In a healthy human being, blood pressure remains within a certain average range. The complex nervous system mechanisms that balance and coordinate the activity of the heart and arterial muscles permit great local variation in the rate of blood flow without disturbing the general blood pressure.

Hemoglobin, the iron-protein compound that gives blood its red color, also plays a role in regulating local variation in blood pressure. Hemoglobin carries nitric oxide, a gas that relaxes the blood vessel walls. Hemoglobin controls the expansion and contraction of blood vessels, and thus blood pressure, by regulating the amount of nitric oxide to which the vessels are exposed.

Two measurements are used to describe blood pressure. Systolic pressure measures blood pressure when the heart contracts to empty its blood into the circulatory system. Diastolic pressure measures blood pressure when the heart relaxes and fills with blood. Systolic and diastolic pressure are measured in millimeters of mercury (abbreviated mm Hg) using an instrument called a sphygmomanometer. This instrument consists of an inflatable rubber cuff connected to a pressure-detecting device with a dial. The cuff is wrapped around the upper arm and inflated by squeezing a rubber bulb connected to it by a tube. Meanwhile, a health-care professional listens to a stethoscope applied to an artery in the lower arm. As the cuff inflates, it gradually compresses the artery. The point at which the cuff stops the circulation and at which no pulsations can be heard through the stethoscope is read as the systolic pressure. As the cuff is slowly deflated, a spurting sound can be heard when the heart contraction forces blood through the compressed artery. The cuff is then allowed gradually to deflate further until the blood is flowing smoothly again and no further spurting sound is heard. A reading at this point shows the diastolic pressure that occurs during relaxation of the heart. Normal blood pressure in an adult is less than 120/80 mm Hg. The first number describes systolic pressure, while the second number describes diastolic pressure.

Blood pressure is influenced by a wide range of factors and varies between individuals and in the same individual at different times. For instance, blood pressure naturally increases with age because the arteries lose the elasticity that, in younger people, absorbs the force of heart contractions. Other factors, such as emotions, exercise, or stress, may temporarily raise blood pressure.

Abnormally high blood pressure, known as hypertension, that remains untreated can lead to stroke, heart attack, and kidney or heart failure. Hypertension may have no known cause or it may result from heart or blood vessel disorders or from diseases affecting other parts of the body. Abnormally low blood pressure, known as hypotension, may be caused by shock, malnutrition, or some other disease or injury.

Mouth Disease Symptoms, Diagnosis, and Treatment

Mouth DiseaseMouth, opening in an animal's body used for taking in food. Mouths are also typically used for making
sounds, such as barks, chirps, howls, and in humans, speech. In most animals, the mouth is found on the face, near the eyes and nose.

Lips, which form the mouth's muscular opening, are an especially familiar part of the body for humans. Lips help hold food in the mouth and are used to form words during speech. They also help form facial expressions, such as smiling and frowning. Lips open wide during a yawn and squeeze together during a whistle. Lips are darker than the surrounding skin because of the many extremely small blood vessels, called capillaries, that show through the skin.

The cheeks form the sides of the mouth. They are composed of muscle tissue that is covered on the outside by skin. Like the lips, the cheeks help hold food and they also play a role in speech.

Inside the mouth is the large, muscular tongue. This extremely flexible muscle is used for eating and swallowing and also for talking. It is attached to the floor, or bottom, of the mouth. Its upper surface is covered with tiny projections, called papillae, that give the tongue a somewhat rough texture. The papillae contain tiny pores that are the site of taste buds, the receptor cells responsible for our sense of taste. There are four kinds of taste buds that are grouped together on certain areas of the tongue’s surface—those that are sensitive to sweet, salty, sour, and bitter flavors.

The roof, or top, of the mouth is called the palate. It separates the mouth from the nasal passages above it. The front part of the palate—the part closer to the lips—is made of bone covered with moist tissue, called mucous membrane. This part of the mouth is known as the hard palate. Behind the hard palate is the soft palate, a small area composed mainly of muscle tissue. During swallowing, the soft palate presses against the back of the throat, preventing food or liquid from moving upward into the nasal passages.

Teeth are used for biting into and chewing food. Their interaction with the lips and tongue helps a person speak clearly. Children have 20 primary teeth, which begin to erupt, or break through the gums, at about six months of age. At six years of age, the primary teeth start to fall out, as permanent teeth replace them. The number of permanent teeth is 32. The crown, or top, of each tooth is covered with enamel, the hardest substance in the human body.

The mouth also contains three pairs of salivary glands. These glands secrete a watery fluid called saliva, which moistens food and the tissues of the mouth. Saliva contains amylase, a digestive enzyme that starts to break down carbohydrates in food even before it is swallowed. Saliva also contains a specialized protein, or enzyme, called lysozyme, which fights bacteria.

Despite the presence of saliva, many kinds of bacteria live in the warm, moist environment of the mouth. Caring for the mouth, called oral hygiene, helps keep these bacteria from multiplying and causing illness. Daily brushing of the teeth and tongue, flossing between the teeth, and regular checkups with a dentist help keep the mouth clean and the teeth and gums healthy (see Dentistry).

The most common ailment of the mouth is tooth decay. Other disorders affecting the mouth include gingivitis, a condition marked by inflamed, infected gums; trench mouth, a severe form of gingivitis that causes bleeding ulcers in the mouth; and thrush, a fungal infection characterized by white sores in the mouth. Oral cancer is a risk for individuals who smoke or chew tobacco or who drink alcohol excessively. A small lump or thickened tissue in the mouth may indicate cancer. It should be checked by a doctor or dentist without delay, as many oral cancers can be cured if treated early.
