The patient care assistant is generally an unlicensed member of the medical team who may be responsible for several tasks that are essential to the delivery of high quality and comprehensive medical care. Most people who pursue this profession find it appealing because they can become employed in an entry-level position without completing several years of college or an extensive training period. In general, new assistants start out as generalists learning the basics of care such as helping with activities of daily living, recording vital signs, and reporting to advanced providers. As individuals gain experience and acquire a few credentials, they may decide that they want to work in a specialized department that offers higher pay and more prestige. While mid-level specialties may only require a certificate of completion from a training program unique to the department and national certification, advanced specialties such as surgery and radiology often require a two to four-year college degree, postgraduate training, national certification, and maybe even state licensure. The tasks that are assigned to an assistant in specialized departments can vary widely and often include preparing patients for procedures, assisting with invasive treatments, providing patient education, and much more.
