Demand for dialysis treatment in the United States has exploded over the past few decades due to the rising prevalence of poor dietary and exercise behaviors. Diseases such as obesity, diabetes, and high blood pressure have had devastating effects on the health and well-being of the public and have led to the creation of hundreds of new dialysis treatment facilities. In order to provide comprehensive and accessible care, administrators have started recruiting thousands of new technicians to perform routine patient care activities. This has resulted in many new employment opportunities for unlicensed allied health personnel who are looking for a career path that has relatively few barriers to entry. Those who choose to pursue this profession can complete their education and training through either an in-house program offered by the employer or through an independent educational institution such as a community college or vocational school that administers a certificate option specific to the specialty. After training has been completed, the technician will typically be required to pass a national certification examination.
