Determinants of pain assessment documentation in intensive care units

Purpose The underassessment of pain is a major barrier to effective pain management, and the lack of pain assessment documentation has been associated with negative patient outcomes. This study aimed to 1) describe the contextual factors related to pain assessment and management in five Quebec intensive care units (ICUs); 2) describe their pain assessment documentation practices; and 3) identify sociodemographic and clinical determinants related to pain assessment documentation. Methods A descriptive-correlational retrospective design was used. Sociodemographic data (i.e., age, sex), clinical data (i.e., diagnosis, mechanical ventilation, level of consciousness, severity of illness, opioids, sedatives), and pain assessments were extracted from 345 medical charts of ICU admissions from five teaching hospitals between 2017 and 2019. Descriptive statistics and multiple linear regression were performed. Results All sites reported using the 0-10 numeric rating scale, but the implementation of a behavioural pain scale was variable across sites. A median of three documented pain assessments were performed per 24 hr, which is below the minimal recommendation of eight to 12 pain assessments per 24 hr. Overall, pain assessment was present in 70% of charts, but only 20% of opioid doses were followed by documented pain reassessment within one hour post-administration. Higher level of consciousness (beta = 0.37), using only breakthrough doses (beta = 0.24), and lower opioid doses (beta = -0.21) were significant determinants of pain assessment documentation (adjusted R-2 = 0.25). Conclusion Pain assessment documentation is suboptimal in ICUs, especially for patients unable to self-report or those receiving higher opioid doses. Study findings highlight the need to implement tools to optimize pain assessment and documentation.

Automated summary

The study investigated the practices of pain assessment and management in five Quebec ICUs and found suboptimal documentation of pain assessment, especially for patients unable to self-report or receiving higher opioid doses. The study emphasizes the importance of implementing tools to optimize pain assessment and documentation.
