The U.S healthcare industry is experiencing a growing shortage of nurses that is expected to increase over the next several years. According to a survey conducted by the American Hospital Association, there are currently over 126,000 vacant positions for registered nurses nationwide. It is also estimated that by the year 2020, there will be a shortage of 400,000 nurses (Joint Commission on Accreditation of Healthcare Organizations). With the number of nurses needed growing daily and reduced nurse-to-patient ratios, the critical shortage threatens to undermine the quality of medical care in the U.S. Studies have already revealed that inadequate nurse staffing tends to increase the risk of complications and deaths associated with them (Journal of American Medical Association). Some of the factors that are driving the demand for nurses in the United States are: Aging nurse population. Declining numbers of nursing professionals and enrollments to nursing schools. Aging U.S population resulting from expanding life expectancies and aging "baby boomers" generation. Increasing demand for healthcare services. Advancing of medical technologies and healthcare treatment methods attracting patients with complex medical conditions who require higher intensity of care.
