In 2001, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) implemented pain management standards calling for the recognition of patients' right to pain relief. According to JCAHO, pain is to be treated as a fifth vital sign, evaluated along with the patient's pulse, blood pressure, core temperature and respiration.

While caring for your patient, you're responsible for educating him or her about your facility's pain management policies, the pain assessment process, and ways of providing pain relief. To assess for pain, you should use a method that is suitable for the patient's age and abilities. Adolescents or adults may be able to describe their pain and to rate its intensity, using a scale from one to 10 in which 10 represents the worst pain imaginable.

For pediatric patients, you might use the FACES scale. Ask a child to show you how much he or she hurts by pointing to one of its six cartoon images, which range from a happy, smiling face to a tearful, sad face. In older adults with cognitive changes, look for signs of pain such as grimaces, agitation, restlessness, inability to sleep, depression or withdrawal. Once you have identified the level of pain, managing it should become part of the plan of care. Become familiar with the analgesics administered to the patient, including the dose and dosing interval, duration of action, time of onset and peak effect, and any side effects or contraindications.

To ensure the appropriate use of the pain medication, document the patient's response to the drugs and the findings of any follow-up assessments. It's crucial, too, to notify the primary care provider if the pain continues unabated, both to help the patient and to avoid a malpractice charge for undertreatment of pain.
