Research studies that were conducted in urban areas in developed countries showed that
positive perceptions of work environment enhanced the levels of nurses' satisfaction and retention ().
Such a positive impact of practice environment on job satisfaction was also recently asserted by Lambrou,Merkouris, Middleton, and Papastavrou (2014) who conducted a systematic review of 14 research studies to examine the impact of work environment on nurses' job satisfaction. Moreover, data from 137 hospitals in Pennsylvania from 1999 to 2006 were analyzed by
Kutney-Lee, Wu, Sloane, and Aiken (2013) to explore if nursing outcomes such as dissatisfaction and turnover are related to changes in nursing practice environment over time. The findings asserted that nursing outcomes were improved over time due to improvement in practice environment.
