PRN, short for the Latin phrase pro re nata, means "as needed" in medical terminology. This abbreviation is used in two primary contexts: medication administration and staffing.
PRN Medication
When used on a prescription, PRN indicates that a medication should be taken only when necessary to alleviate symptoms, rather than on a scheduled basis. The patient determines when the medication is needed, based on their individual symptoms.
- Example: A doctor might prescribe pain medication PRN for post-operative pain. The patient would take the medication only when they experience pain.
PRN Staffing
In healthcare staffing, PRN (or per diem) refers to employees who work on an "as needed" basis. These employees are not guaranteed regular hours and are called upon to fill staffing gaps or cover absences. This can include nurses, doctors, and other healthcare professionals.
- Example: A hospital might employ PRN nurses to fill shifts when regular staff are unavailable or when there's increased patient volume.
The flexibility of PRN work arrangements benefits both employers and employees. Employers can easily adjust staffing levels based on need, while employees gain work schedule flexibility.
Key Characteristics of PRN:
- Flexibility: Both medication usage and staffing are dictated by need, not a pre-determined schedule.
- Situational Dependence: The action (taking medication or working a shift) is contingent on a specific circumstance or symptom.
- Latin Origin: The abbreviation originates from the Latin phrase "pro re nata," emphasizing its historical roots.
