The documentation of pain intensity and its influences on care in the emergency department

Background: Assessment and reassessment of self reported pain intensity scores form the basis of acute pain care in the emergency deprtment (ED), however are frequently undocumented. The effects of not documenting pain assessments on time to first analgesic medication (TTA) and ED length of stay (EDLOS) are unknown. Methods: This is a retrospective cross-sectional study to investigate the association between documented evidence of pain intensity scores, TTA and EDLOS in the ED. It also examined the factors associated with the documentation of pain intensity scores. Univariate and multivariable modelling was used on a random sample of presentations. Results: There were no statistically significant associations between the documented evidence of pain intensity scores and TTA or EDLOS. Modelling suggests that patients were less likely to have documented evidence of pain intensity scores if they were male, were streamed to the fast-track treatment area, had a lower burden of co-morbidities, or when the general departmental workload was increased. Conclusions: The documentation of pain intensity scores was not associated with TTA or EDLOS. Some demographic, illness and workload factors are associated with the lack of pain intensity score documentation, however, the effect on patients outcomes needs further investigation.
