We study time evolution of quantum Fisher information (QFI) and entanglement for two three-level atomic systems influenced by Stark effect and Kerr-like medium. It is seen that Stark and Kerr media play dominant role during the time evolution of the quantum system. Dynamics of QFI is heavily influenced under the effect of linear Kerr medium as compared to the entanglement. However, the effect of nonlinear Kerr medium is more prominent on the entanglement. Similarly, Stark effect strongly influences the entanglement of two three-level atomic systems. Furthermore, the entanglement evolves with time as we increase the Stark effect. Finally, the quantum system is found highly sensitive to these environmental influences.
