Due to the shortage of nurses in the Irish health system; good health outcomes for patients in hospital and rapid responsiveness are difficult to achieve. The ratio of nurse to patients is critically determining satisfactory patient outcomes. The number of patients per nurse is a deciding factor resulting in life or death outcomes. According to University of Pennsylvania the optimal workload is four patients per nurse per shift. A 31% rise in mortality rate was identified when the nurse to patient ratio increased to 1:8. In Ireland it is
