With the overall ageing of the population, and the continuous problems of short staffing in the health care industry, there is a growing need for qualified patient care personnel across the nation to assist the infirm and elderly with custodial care and rehabilitation services. Patient Care Technicians are usually trained on the job, which allows for numerous inconsistencies and improper health care practices. Properly trained and certified technicians will greatly assist the ailing industry with adequate, competent nursing assisting staff. PCT's are multi-skilled individuals who provide basic patient care services under the supervision of qualified physicians, nurses and other medical professionals. PCT's are typically employed in hospitals, nursing homes, physician's offices, clinics, assisted living facilities and in-home health care settings to provide basic nursing care services to infants, children and adults. Self-employment prospects are high in this vocation, especially for home health care aides, for the elderly, convalescent and disabled persons needing personalized attention at their residences.
