The Medical Assisting Profession

Overview of the Medical Assisting Profession

• The medical office and other healthcare settings rely on the diligence and commitment of the healthcare team. Many valuable team players perform specific tasks and serve in specific roles to ensure efficient operations.

• This study guide covers the roles, responsibilities, scope of practice, and standards of care of the medical assistant and similar healthcare workers, including expected characteristics and workplace attributes.

• The Medical Assistant (MA) fulfills a vital role in healthcare and represents one of the nation's fastest-growing careers, according to the United States Bureau of Labor Statistics.

• The profession's growth is driven by:

  • Increasing numbers of physician's offices and outpatient care facilities.

  • Technological advancements helping people live longer, healthier lives.

  • The growing population of elderly Americans.

• Scope of Practice: This refers to the procedures and actions that a medical assistant is legally permitted to perform. It is defined by state law and the supervising physician's license. Scope varies by state.

• Core Supervision Rule: An MA must always work under the direct supervision of a licensed provider. They cannot independently assess, diagnose, or create treatment plans.

• Respondeat Superior: This legal concept means "let the master answer." In a court of law, the physician is ultimately responsible for the actions and errors of the health professionals working under their supervision.

Historical Development of Medicine

• Early Medicine

  • Treatments were based on trial and error using plants and animals from the environment.

  • Examples: Healers used ginger for gastrointestinal problems, licorice to soothe inflamed mucous membranes, peppermint for indigestion, chamomile to soothe nerves, leeches for wounds, and snake venom as an antivenin.

  • Disease was often viewed as having supernatural origins (evil spirits, angry gods), leading to the use of sorcerers, shamans, talismans, magical charms, and incantations.

• Hippocrates ($460$ – $370\,BC$)

  • Known as the "Father of Medicine."

  • Rejected supernatural causes for disease, believing instead in natural causes related to the four humors of the body: blood, phlegm, black bile, and yellow bile.

  • Postulated that health requires these humors to be in perfect balance through wellness behaviors: proper diet, exercise, rest, positive attitude, and moderation.

• Galen ($129$ – approx. $199\,AD$)

  • A Roman physician, surgeon, and philosopher.

  • Dissected monkey and pig cadavers to study anatomy and physiology.

  • Discovered that arteries carry blood, the heart pumps blood through the system, and the brain controls the body via nerves.

• Andreas Vesalius ($1514$ – $1564\,AD$)

  • Known as the "Father of Modern Anatomy" due to his extensive dissections of the human body.

• William Harvey ($1587$ – $1657\,AD$)

  • The first person to describe the cardiovascular system and the properties of blood in detail.

• Thomas Sydenham ($1624$ – $1689\,AD$)

  • Often referred to as the "English Hippocrates."

  • Worked in the early science of epidemiology to discover causes of disease.

  • Emphasized extensive patient observation and documentation in patient records.

• Antonie van Leeuwenhoek ($1632$ – $1723$)

  • Referred to as the "Father of Microbiology" and the first microbiologist.

  • Developed the microscope to observe microbes.

• The College of Philadelphia Department of Medicine ($1765$)

  • Now the University of Pennsylvania School of Medicine; established as the first medical college in the United States.
