If there are expert systems and dose checks, why do we still need the clinical pharmacist?

Trends in patient care, along with escalating health care costs, and the demand for medication safety may provide a breadth of opportunities for clinical pharmacists. Service and drug use guidelines development, medication error prevention, quality assurance, and pharmacoeconomic assessment are areas in which skills of the oncology pharmacist may be used. Although expert systems may aid the pharmacist in these areas, such systems cannot replace the professional.
