Final answer:
In the pharmacist's absence, they must remain accessible to ensure continuous, safe, and effective medication management, either by being on call or using systems like remote order review or consultation.
Step-by-step explanation:
During times of hospital pharmacist absence, a pharmacist shall be accessible to the hospital either by being on call or by providing a system which ensures patients have access to pharmacy services. In such situations, the pharmacist must ensure that medication therapy continues to be safely and effectively managed, often through protocols established in collaboration with the healthcare team. This coverage might include remote review of medication orders, consultation via telephone, or use of automated dispensing systems overseen by pharmacy technicians with remote pharmacist supervision.
