History of Health Care

State Standard 1) Synthesize information found in news media, professional journals, and trade magazines to create a report and/or presentation on the historical evolution of healthcare in the United States. Use a timeline or other graphic to illustrate major developments beginning with the first medical school through today.

Objectives Students will: Identify medical/health care milestones that have led to advances in health care. Predict where and how factors such as cost, managed care, technology, and aging population, access to care, alternative therapies, and lifestyle behavior may affect various health delivery system models.

4000 BC – 3000 BC Primitive Times Illness and diseases were a punishment from the Gods Tribal witch doctors treated illness with ceremonies Herbs and plants used as medicines (morphine and digitalis) Trepanation or trephining (surgically removig a piece of bone from the skull) Average life span was 20 years

1200 BC –200 BC Ancient Greeks First to observe the human body and the effects of disease – led to modern medical sciences. Believed illness is a result of natural causes Used therapies such as massage, art therapy, and herbal treatment Stressed diet and exercise as ways to prevent disease Average life span was 25-35 years

753 BC – AD 410 Ancient Romans First to organize medical care by providing care for injured soldiers Later hospitals were religious and charitable institutions in monasteries and convents First public health and sanitation systems by building sewers and aqueducts Galen established belief that the body was regulated by four body humors; blood, phlegm, black bile, and yellow bile Life span was 25-35 years

Current Trends in Health Care

State Standard 1) Synthesize information found in news media, professional journals, and trade magazines to create a report and/or presentation on the historical evolution of healthcare in the United States. Use a timeline or other graphic to illustrate major developments beginning with the first medical school through today.

Objectives Students will: Identify medical/health care milestones that have led to advances in health care. Predict where and how factors such as cost, managed care, technology, and aging population, access to care, alternative therapies, and lifestyle behavior may affect various health delivery system models.

Cost Containment Cost of health care began rising due to: Technological advances Aging population Health-related lawsuits Cost Containment measures include: Diagnostic related groups (DRG) Combination of services Outpatient services Mass or bulk purchasing Early intervention and preventive services

Health care facilities specialized to include: Home health care Hospice care Geriatric care Types of facilities Omnibus Budget Reconciliation Act (OBRA) Telemedicine

Emphasis on promoting wellness of the whole individual: Physical wellness Emotional wellness Social wellness Mental and intellectual wellness Spiritual Wellness Holistic Health

Alternative and Complementary Methods of Health Care Chinese medicine practitioners Chiropractors Homeopaths Hypnotists Naturopaths

National Health Care Plan Has become a leading topic of debate due to the increasing number of uninsured Americans Education and preparation for a potential pandemic Due to the high rate international travel, the possibility for a devastating pandemic has increased

Bioengineering Includes fields in which problems are solved by the design of technologies used in biology and medicine for example: genetic engineering additive manufacturing used in health stem cell research organ and tissue transplants

Genetic Engineering Is the use of technology to change DNA code transfer of genetic material of living cells to make them capable of performing new functions Uses are still being developed many more studies must be done to discover its full potential and to verify and improve the safety of procedures many individuals question the ethics and possible consequences of some uses

Genetic Engineering Has applications in health science including: the use of genes to make drugs specific to a disorder the use of genes to choose drugs and dosages which will be most effective for a specific patient the use of specific genes to create more effective vaccines

Genetic Engineering Has applications in health science including: the isolating of genes to study in the hope of curing hereditary diseases known as gene therapy the duplicating of genes to use them in a different part of the body or even in a different person’s body known as cloning

Stem Cells Are undifferentiated cells they can divide to become any number of different types of cells skin cells, muscle cells, etc. makes them good candidates for research in medicine if they can be stimulated to become organ cells, they can be used to aid patients in need of transplant

Embryonic Stem Cells Are found in a developing human embryo very early stage of development Can become any type of tissue Use is controversial to obtain embryonic stem cells, fetal tissue must be destroyed, creating ethical concerns

Adult Stem Cells Are naturally found throughout the body Are more limited in their potential than embryonic stem cells for example, bone marrow can become any type of blood cell and brain stem cells can become neurons and other types of nerve cells

Cord Blood Stem Cells Are taken from the umbilical cord structure attaching a fetus to the womb Are hematopoietic stem cells can differentiate into any blood cell type similar to those in bone marrow Can be stored right after birth for later use Have been successfully used in treating many diseases leukemia (cancer of white blood cells) anemia (too few functioning blood cells) eye tumors

Transplants Are operations in which a healthy organ or tissue from another person is placed in the patient’s body when medical conditions cause organ or tissue failure organs and tissues include: heart small intestine heart valves liver tendons corneas ligaments kidneys skin bones lungs veins pancreas blood

Transplants May come from a deceased donor in cases where the organ is necessary for survival for example, the heart May come from a live donor in cases where a person has more than one of the organ and can survive after losing one for example, the kidney in cases where a portion of the organ can be taken and the organ has the ability to regenerate and regain full function for example, the liver

Transplants Require: the donor and patient have compatible blood types and similar organ size relatives are preferred living donors the organ be placed in the patient quickly after having been removed from the donor time allowances vary by organ the patient take drugs to prevent the risk of transplant rejection the immune system may view the new organ or tissue as a foreign threat and attack it

Transplant Technology Continues to advance doctors are developing new procedures to decrease the chances of transplant rejection by preparing the patient’s immune system with specific drugs before transplant by transplanting bone marrow along with the necessary organ systems are being developed to: allow organs to remain outside of the human body for extended periods enhance the health of donated organs before transplant

Activity Stem Cells: Where Do You Stand? Perform research on the topic of medical use of stem cells. As you do your research, answer the following questions:  What are stem cells  How have stem cells been used in the past  When were they first used  How are stem cells used currently  What are some of the potential negative and positive results that might occur with the use of stem cells in a medical procedure  Why is there controversy surrounding the use of stem cells ****You will be writing an essay over the information that you just researched and your thoughts about stem cells. Do you think this is a good idea, why or why not.
