Interruptions Experienced by Emergency Nurses: Implications for Subjective and Objective Measures of Workload.

INTRODUCTION: This study aimed to describe interruptions experienced by emergency nurses and establish convergence validity of 1 objective workload measure by linking interruption characteristics to objective and subjective measures of workload. METHODS: Interruptions were captured in real time across 8- or 12-hour shifts using a previously validated Workflow Interruptions Tool (WIT). Data collected on each interruption included type, priority, and location where the interruption occurred. At mid- and end-shift, the Surgery Task Load Index (SURG-TLX) and the Rapid Cognitive Assessment Tool (RCAT) were administered to participating nurses to measure workload subjectively and objectively. RESULTS: Thirty-eight emergency nurse shifts were observed. A total of 3,229 interruptions were recorded across 372.5 clinical hours and 38 shifts (means [M] = 85.0 interruptions per shift, standard deviation [SD] = 34.9; M = 8.7 interruptions per hour, SD = 3.36). The median duration per interruption was 13.0 seconds. A moderate positive association was identified between the number of interruptions experienced during a shift and the increased overall SURG-TLX workload reported at end-shift, r(36) = 0.323, P = 0.048. Also, a moderate positive association was identified between increased reaction times during the RCAT task and increased mental demand experienced at end of shift, r(36) = 0.460, P < 0.001. DISCUSSION: This study observed interruptions throughout the entirety of a nursing shift and found that the majority of interruptions caused by the environment were low priority. Targeting interventions to reduce low-priority and environmental interruptions may aid in alleviating the impact of interruptions on clinical staff and patient care. Furthermore, results demonstrate that the frequency of interruptions was perceived to increase the nursing staff workload overall.

Impact of Scribes on Billed Relative Value Units in an Academic Emergency Department.

BACKGROUND: Scribe use throughout health care is becoming more common. There is limited peer-reviewed literature supporting this emerging role in health care despite rapid uptake of the role. OBJECTIVES: Our study assesses impact of scribes on relative value units (RVUs) in adult and pediatric emergency departments (EDs). METHODS: A prospective cohort study was developed in a tertiary academic ED. Charts were coded by an external billing and coding company, then returned and mapped by International Classification of Diseases, 9th revision diagnostic codes. After training by a staff member with significant experience in implementing scribe programs, scribes provided 1-to-1 support to a provider as staffing allowed. Comparisons were made between scribed and nonscribed visits. RESULTS: There were 49,389 patient visits during the study period (39,926 adult [80.84%] and 9463 pediatric [19.16%] visits), of which 7865 (15.9%) were scribed. For adults, scribed visits produced 0.20 additional RVUs per patient (p < 0.001). Scribes generated additional RVUs in Emergency Severity Index (ESI) 2 (p < 0.001) and 3 (p < 0.001) patients. There were variable effects of scribes on RVUs by diagnostic codes. For pediatric patients, scribed encounters generated 0.08 fewer RVUs per patient (p = 0.007). ESI score had no effect on RVUs. The impact of scribes on pediatric diagnostic groupings was inconsistent. CONCLUSIONS: Scribes had a positive impact on RVUs in adult but not pediatric patients. Among adults, scribes led to higher RVUs in ESI 2 and 3 but not 4 and 5 patients, perhaps suggesting a limitation to improve revenue capture on lower-acuity patients.
