Objectives Overcapacity issues plague emergency departments (EDs). Studies suggest triage liaison providers (TLPs) may shorten patient length of stay (LOS) and reduce the proportion of patients who leave without being seen (LWBS), but these results are not universal. Previous studies used physicians as TLPs. We evaluated whether a physician assistant (PA), acting as a TLP, would shorten LOS and decrease LWBS rates. Methods The authors used an observational cohort controlled before-and-after study design with predefined outcome measures, comparing eight pilot days to eight control days. The TLP evaluated all Emergency Severity Index (ESI) level 3, 4, and 5 patients, excluding pediatric and behavioral health patients. Results Three hundred fifty-three patients were included on pilot days, and 371 on control days. LOS was shorter on pilot days than control days (median 229 minutes [IQR 168 to 303 minutes] vs. 270 minutes [IQR 187 to 372 minutes], p < 0.001). Waiting room times were similar between pilot and control days (median 69 minutes [IQR 20 to 119 minutes] vs. 70 minutes [IQR 19 to 137 minutes], p = 0.408), but treatment room times were shorter (median 151 minutes [IQR 92 to 223 minutes] vs. 187 minutes [IQR 110 to 254 minutes], p < 0.001). Finally, a lower proportion of patients LWBS on pilot days (1.4% vs. 9.7%, p < 0.001). Conclusions The addition of a PA as a TLP was associated with a 41 minute decrease in median total LOS, and a lower proportion of patients who LWBS. The decrease in total LOS is likely attributable to the addition of the TLP, with patients having shorter duration in treatment rooms on pilot days compared to control days.

Objectives Patient throughput is an increasingly important cause of emergency department (ED) crowding. The authors previously reported shorter patient length-of-stay (LOS) when adding a triage liaison provider, which required additional personnel. Here, the objective was to evaluate the effect of moving a fast track provider to the triage liaison role. Methods This was a prospective observational before-and-after study design with predefined outcomes measures. A ‘standard staffing’ situation (where an advanced practice provider [APP] staffed treatment rooms in the fast track) was compared with an APP performing the triage liaison staffing role, with no additional staff. Eleven intervention (‘triage liaison staffing’) days were compared with 11 matched control (‘standard staffing’) days immediately preceding the intervention. Total LOS was measured for all adult Emergency Severity Index (ESI) 3, 4, and 5 patients (excluding behavioral health patients), and results were compared using Wilcoxon rank sum and chi-square tests. Results A total of 681 patients registered on control days, and 599 on intervention days. There was no significant difference in total patient LOS: median 273 minutes, IQR 176 to 384 minutes on intervention days vs. median 253 minutes, IQR 175 to 365 minutes on control days (p = 0.20). There was no difference in LWBS rates (n = 48, 7% on control days vs. n = 35, 6% on intervention days; p=0.38). Secondary analysis of only ESI 3 patients showed no difference in total LOS between periods (median 284 minutes, IQR 194 to 396 minutes on intervention days vs. median 290 minutes, IQR 217 to 397 minutes on control days; p = 0.22). There was, however, significantly greater total LOS for ESI 4 and 5 patients during the intervention period (median 238 minutes, IQR 124 to 350 minutes on intervention days vs median 192 minutes, IQR 124 to 256 minutes on control days; p = 0.011). Conclusions The previously reported benefits on patient LOS and LWBS rates after adding a triage liaison (resource additive) were lost when that provider was moved from fast track to the triage role (resource neutral). While the triage liaison provider role may be a way to improve ED throughput when additional resources are available, as evidenced by our prior study, the triage liaison model itself does not appear to replace the staffing of treatment rooms, as evidenced by this study.
