Emergency department management of patients with rib fracture based on a clinical practice guideline.

BACKGROUND

Clinical practice guidelines (CPGs) have the ability to increase efficiency and standardize care. A CPG based on forced vital capacity (FVC) for rib fractures was developed as a tool for triage of these patients. The objectives of this study were to assess the efficacy and compliance of physicians with this rib fracture CPG.

METHODS

Patients >18 that were discharged from an urban level 2 trauma center emergency department (ED) between the dates of January 1, 2014, to December 31, 2016, were eligible for the study. Demographics, mechanism, outcomes and FVC were abstracted by review of the electronic medical record. Compliance with the CPG was examined, and comparisons were made between patients successfully discharged and patients who returned.

RESULTS

455 patients met were identified during the study period. 233 were eligible after exclusions. 64% of the cohort was male with median age of 53 years. Falls were the most common mechanism (59.6%). The median number of rib fractures was 2 and median FVC 2500 mL. 28 (12.0%) of the 233 returned to the ED after discharge. The groups were well matched with no significant differences. The most common reason for return was pain (95%). Adjusted analysis showed that increasing age (adjusted OR (AOR) 0.968) and FVC (AOR 0.999) were independent predictors. Adherence with the CPG was good for hemothorax/pneumothorax and bilateral fractures (96%), but lagged with the number of fractures (74%).

CONCLUSIONS

This study confirms that the rib fracture CPG is safe and an FVC of 1500 mL is a safe criterion for discharging patients with rib fractures. Interestingly, it appears that older age is protective. More work needs to be done on effective pain control to decrease return to ED visits using this CPG.
