The work of these allied medical professionals is multifaceted and vital to the success of a physician practice. The American Association of Medical Assistants (AAMA) recently conducted an occupational analysis in which they isolated the job responsibilities/duties that Certified medical assistants (CMAs) most frequently perform:

  • Ensuring a high level of effective interaction with staff and patients as to optimize workflow efficiency
  • Maintaining accurate patient records

  • Documenting patients, observations, and clinical treatments
  • Ensuring that all care is provided within ethical and legal boundaries
  • Identifying consequences of failing to understand the scope of their practice

Although specific medical assistant job duties may vary according to the size and specialty of the medical practices they work for, a general medical assistant job description will likely include the following:

    • Reporting directly to a physician, clinical coordinator, or practice administrator
    • Performing medical procedures and tests under the direct supervision of a physician or physician assistant
    • Assisting physician exams and tests
    • Measuring and recording vital signs, including:

In some states, medical assistants may perform certain procedures, such as blood draws, ultrasounds, and echocardiograms, while in other states these procedures cannot be performed. Generally speaking, however, it is up to the discretion of the physician or office administrator regarding the duties and responsibilities of its staff of medical assistants.

Required Knowledge and Skills

Medical assistant jobs require knowledge of the healthcare field, the medical specialty of the office or center in which they work, and medical terminology. They must also have exceptional people skills; good grammar and spelling; excellent phone etiquette; a high degree of professionalism; and top-notch organizational skills, including the ability to multi-task.

The AAMA reports that most of today’s employers seek medical assistants who have completed a degree or certificate program accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP), the Accrediting Bureau of Health Education Schools (ABHES), or the Committee on Accreditation for Ophthalmic Medical Personnel.

Further, many employers seek national certification from such recognized associations as:

  • The American Association of Medical Assistants
  • The American Society of Podiatric Medical Assistants
  • The American Medical Technologists
  • The Joint Commission on Allied Health Personnel in Ophthalmology

One of the most recognized certifications is the Certified Medical Assistant (CMA) through the American Association of Medical Assistants. The CMA designation indicates that the medical assistant has graduated from a recognized medical assisting program and has passed the CMA certification examination.

The CMA certification examination assesses candidates in three, major areas: general medical knowledge, administrative knowledge, and clinical knowledge.

Qualities of an Outstanding Medical Assistant

Today’s employers often seek medical assistants who possess more than just the proper degree or certification. Some of the most widely sought after traits of outstanding medical assistants include:

  • Excellent communication skills: Medical assistants must be able to convey a physician’s medical lingo to patients in a way that they understand. They must also ensure that all information – whether from a patient, physician, or insurance company – is transmitted with a high degree of accuracy.
  • Excellent listener: One of the most important traits of medical assistants is their listening skills. Medical assistant jobs often involve listening carefully to everything from instructions and requests from physicians to the concerns and needs of patients.
  • Compassionate/Empathetic: Compassion in the medical field is essential, particularly when patients are in need of comfort and support.
  • Adaptable: A medical assistant’s job may vary from one day to the next or from one minute to the next. Therefore, organization is vital, the ability to multi-task is a must, and adaptability is essential.
  • Stress Tolerance: A physician’s office may be a very hectic environment, at times. From patient care and scheduling to insurance billing and physician demands, medical assistants must be able to handle the everyday stressors that may accompany this profession.
  • Integrity: Handling privileged information, ensuring confidentiality, and respecting a patient’ privacy are all vital components to being a top-notch medical assistant. In addition to understanding and adhering to the HIPAA Privacy Rule, which is paramount to the profession, medical assistants must employ a high degree of integrity when dealing with sensitive situations and documents.
