Evaluation of an advanced practice provider emergency department critical care step‐down unit

Abstract

Objective In response to concerns about patient care and safety, our urban, tertiary care, Level 1 trauma center adult emergency department (ED) created an advanced practice provider‐staffed critical care step‐down unit (CCSU). We conducted a comprehensive evaluation of the CCSU's impact on patient care, safety, and ED operations. Methods We compared ED length of stay, return visits to the ED within 72 hours, billing code assignments (current procedural terminology evaluation and management [CPT E&M] codes), and quality of electronic health record documentation per QNOTE for the 2 years after the CCSU was initiated (CCSU period) versus before its initiation (pre‐CCSU period). Results There were 31,418 critical care ED patient visits in the pre‐CCSU period and 33,396 in the CCSU period. Median ED length of stay did not change overall between the CCSU versus pre‐CCSU period (∆1 [95% confidence interval (CI) = −2.4, 4.4] minutes), but decreased for patients who remained in the critical care suites (∆‐4 [95% CI = −7.8, −0.2] minutes). 72‐hour return ED visits also did not change overall (∆0% [95% CI = −0.1, 0]), but decreased for patients who remained in the critical care suites (∆0.4% [95% CI = −0.05, −0.4]). CPT E&M billing increased for highest‐level visits (99,291: ∆1.3% [95% CI= 0.5, 2.0]). Quality of electronic health record documentation as measured by QNOTE also improved (∆11.5% [95% CI = 4.9, 18.1]). Conclusion This ED's CCSU performance metrics indicate at least moderate improvement in ED length of stay, 72‐hour return visits, critical care patient billing, and electronic health record documentation. EDs elsewhere can consider implementation of this advanced practice provider‐staffed solution to improvement in critical care in ED.

Analysis of nurse practitioner practice in US emergency departments: Evidence supporting educational preparation, credentialing, scope of practice, and outcomes

“…• System outcomes: Studies have supported that including NPs in ED staffing models allows physicians to treat higher acuity patients (Pines et al, 2020). With creation of an NP- and PA-staffed critical care step-down unit established in a Level 1 trauma center adult ED, “at least moderate improvements in ED length of stay” as well as 72-hr return visits” (p. 1) were noted (Murphy et al, 2020). …”
