Impact of a Clinical Therapeutic Intervention on Pain Assessment, Management, and Nursing Practices in an Intensive Care Unit: A before-and-after Study.

BACKGROUND

Accurate pain assessment and management constitute a major challenge for medical and nursing staff in intensive care units (ICUs). A distinct recollection of pain is reported by high proportions of ICU patients.

PURPOSE

A clinical therapeutic intervention directed at improving pain assessment and management in critically ill patients who are unable to communicate was implemented at an Italian ICU.

METHODS

In this before-and-after study, data were collected before (T) and after (T) the adoption of a protocol involving pain assessment with an ad hoc behavioral pain scale and the administration of analgesics, rather than sedatives, to patients with intermediate to high pain scores.

RESULTS

The main outcome measure was pain recollection a year after discharge; secondary outcome measures were the use and doses of sedatives and analgesics. A significantly (p = .037) smaller proportion of patients treated after protocol adoption recollected feeling severe pain compared with patients treated before the protocol was introduced. This group also received significantly (p < .001) fewer sedatives and significantly (p = .0028) more anti-inflammatory drugs and analgesics on an "as needed" basis. The administration of strong analgesics was similar in the two groups. The intervention was implemented in 70.5% of patients with intermediate to high pain scores.

CONCLUSIONS

Appropriately trained ICU nurses have the potential to help adopt pain relief and prevention measures during nursing care and to contribute to the successful management of sedation and analgesia. Further studies of larger patient samples are needed to monitor the stability of results over time and to explore the efficacy of the approach in other populations, such as pediatric and neonatal ICU patients.
