Final answer:
The concern is the integration of information systems with the acquisition of new hospitals. Challenges may arise in data sharing, interoperability, and standardization.
Step-by-step explanation:
The concern in this situation is the integration of information systems. With the acquisition of five more hospitals, the 10 hospital chain will have hospitals with different vendors supplying their information systems. This can result in challenges in data sharing, interoperability, and standardization. It is important to ensure that the new hospitals' information systems can effectively communicate with the existing ones, while maintaining data privacy and security.
