Medical Developments Across Historical Civilizations

  • Ancient Egyptians:

    • Were the first people to record formal medical records.

    • Religious priests acted as medical physicians.

    • Believed the human body was a system of natural channels for:

    • Air

    • Tears

    • Blood

    • Sperm

    • Urine

    • Feces

    • Believed that when one or multiple of these channels became clogged, it caused a person to fall ill.

  • Ancient Chinese:

    • Believed in a holistic approach to medicine rather than focusing strictly on physical symptoms.

    • Holistic definition: Healing the mind, body, and spirit as an interconnected whole.

    • Practiced acupuncture, an ancient treatment technique involving the insertion of thin needles into specific locations on the body.

  • Ancient Greeks:

    • Observed the direct physical effects of disease on the human body.

    • Emphasized healthy diet and personal cleanliness to prevent illness.

    • Believed that illness resulted from natural causes rather than spiritual or supernatural factors.

    • Used physical therapies such as massages and herbal treatments to care for sick people.

  • Romans:

    • Built upon the medical findings of the Greeks and conducted further research.

    • Established a clear connection between disease transmission and filthiness/unsanitary environments.

    • Built major public health infrastructure, including sewers and aqueducts, to carry sewage and waste away from populated cities.

    • Created the first dedicated hospitals to allow patients to receive organized medical care.

  • Dark Ages:

    • Followed the fall of the Roman Empire.

    • The formal study of medicine was strictly prohibited.

    • Religious prayer was used as the primary method to treat sick individuals.

    • Sick people sought out medical guidance and treatments primarily from priests and monks.

  • Middle Ages:

    • Experienced a revival of older medical practices as monks translated early medical writings from Greek and Roman scholars.

    • Established dedicated Medical Schools to systematically train new physicians.

    • Arab doctors in the Middle East were required to obtain an official license in order to practice medicine.

    • Ended with the outbreak of the Bubonic Plague (Black Plague), a devastating pandemic that killed over half the total population of Europe and Asia.

  • Renaissance:

    • Known as the rebirth of scientific medicine.

    • Dissection of human bodies was officially permitted and studied, leading to groundbreaking discoveries about human anatomy and physiology.

    • The invention of the printing press allowed medical research and scientific information to be published and distributed widely to larger audiences.

    • The availability of printed texts resulted in an increase in general population literacy.

    • Marked an unprecedented era of rapid scientific advancements and medical breakthroughs compared to any prior period in history.

Health Informatics Services and Medical Information

  • Health Informatics Services Categories:

    • Health Informatics Services center entirely around patient data and medical information.

    • Composed of 3 main categories:

    • Health Information Management (HIM): Focuses on the maintenance, governance, and organization of patient record systems.

    • Health Information Technology (HIT): Focuses on the technical infrastructure, software, hardware, and digital tools used to store and transmit healthcare data.

    • Health Informatics (HI): Focuses on applying computer science, information systems, and data analysis to improve healthcare outcomes and patient care delivery.

  • Components of a Medicinal Record:

    • Medical history (past illnesses, surgeries, diagnoses, and treatments)

    • Family medical history (hereditary health factors and diseases in blood relatives)

    • Personal identifying information (identifying credentials including birth date and Social Security number)

    • Contact information (address, phone numbers, emergency contact details)

Roles and Duties of Medical Assistants

  • Administrative Tasks:

    • Scheduling patient appointments

    • Admitting patients into the hospital facility

    • Drafting formal letters and memos

    • Processing patient billing and payment information

    • Filing insurance forms and claims

  • Clinical Tasks:

    • Taking and documenting patient medical histories

    • Measuring and recording vital signs

    • Performing routine laboratory tests

    • Collecting laboratory specimens and samples

    • Performing phlebotomy (drawing blood)

    • Assisting physicians during patient physical examinations

Healthcare Careers, Education, and Career Pathways

  • Exploring Healthcare Careers:

    • Personal Traits: Evaluating key personality traits and temperaments necessary for succeeding in healthcare environments.

    • Self-Assessment: Utilizing self-assessment questions to evaluate personal skills, strengths, interests, and abilities.

    • Path Selection: Evaluating all necessary personal and professional factors when selecting an appropriate career path in the medical field.

  • Levels of Education in Healthcare:

    • High School Diploma

    • Formal on-the-job training

    • Technical School / Trade School

    • Licensure / Certification

    • Community College (Associate's Degree)

    • 4-Year College or University (Bachelor's Degree)

  • Five Healthcare Career Pathways:

    • Therapeutic Services: Careers focused on maintaining or changing the health status of a patient over time through direct hands-on care, treatment, counseling, or education.

    • Diagnostic Services: Careers focused on performing tests, imaging, and evaluations to aid in the detection, diagnosis, and identification of diseases or physical conditions.

    • Health Informatics Services: Careers focused on managing patient health records, medical data, healthcare systems, and information technology.

    • Support Services: Careers focused on maintaining a clean, sanitary, safe, and effective environment for patients and healthcare workers.

    • Biotechnology Research and Development: Careers focused on bioscience research and scientific innovation to develop new drugs, therapies, and medical devices.
