Appropriateness of behavioural scales in the monitoring of pain in the critically ill patient unable to self-report

Appropriateness is a dimension of quality that evaluates the effective use of technologies, resources or interventions in specific situations or populations, assessing whether our interventions do more benefit than harm.

The evidence regarding pain monitoring in the critically ill patient points to the periodic assessment of pain using appropriate tools, with the aim of improving pain management and more efficient use of analgesics in the intensive care unit. The first step would be to assess the patient's ability to communicate or self-report and, based on this, to select the most appropriate pain assessment tool. In patients who are unable to self-report, behavioural pain assessment tools are recommended.

When we talk about the suitability of behavioural scales for pain monitoring in critically ill patients unable to self-report, we refer to their use with a clear clinical benefit, i.e. using the right tool for pain assessment to be effective, efficient and consistent with bioethical principles.

To our knowledge, there are no published data on the suitability of pain assessment tools in unable to self-report critically ill patients, so, in the framework of continuous quality improvement in pain care, new research should incorporate this approach by integrating the best scientific evidence with current clinical practice.
