Background: Today's healthcare organizational climate become more complex than before due to its
impact on nurses' productivity as well as their involvement in decision-making (Munyewende et al.,2014).
Healthcare members not fully understand organizational climate effect on nurses' involvement in decision
making and work productivity. This lack of understanding may cause negative patient outcomes. Aim: The
study aims to assess nurses' perception of organizational climate and its relationship with their involvement
in decision making and work productivity. Study design: A descriptive correlational study was utilized.
Subjects and setting: A sample of 297 nurses were included in this study classified as 195 nurses in surgical
care units and 102 nurses in medical care units of the Alexandria Main University Hospital. Tools: Three tools
were utilized namely organizational climate measure, decisional involvement scale and healthcare
productivity survey. Results: The study finding highlighted that the majority (88.2%) of studied nurses
perceived their organizational climate as good, less than half (43.1%) of the studied subjects had a moderate
level of decision involvement, there was a high level of work productivity and decision involvement with
excellent organizational climate. Conclusion: The study concluded that there was a statistically significant
relationships between organizational climate and both decision involvement (r=0.130, p=0.025), and health
care productivity (r=0.345, p=0.000). Recommendations: hospital nursing administrators should conduct
periodic meetings with nurses, motivate them through appropriate reward system and encouraging open and
transparent communication to improve climate and nurses' decision-making abilities.
