What are the roles of ancillary services in hospitals?

Ancillary services play a vital role in hospitals by providing essential support services that complement primary medical care. These services include areas such as radiology, which offers imaging services vital for diagnosis, and pharmacy, which ensures that patients receive the correct medications safely and efficiently. These support services are crucial because they help enhance patient care, streamline hospital operations, and ensure that primary healthcare providers have the necessary resources to treat patients effectively. By fulfilling this role, ancillary services improve overall hospital performance and contribute to positive patient outcomes. The other options focus on financial management, administrative oversight, and human resources, which are important in their own right but do not define the core function of ancillary services in a hospital setting.
