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.

Surveillance: A Nursing Intervention for Improving Patient Safety in Critical Care Environment.

BACKGROUND: Nursing surveillance has been identified as a key intervention in early recognition and prevention of errors/adverse events. Nursing Intervention Classification (NIC) defines surveillance as "the purposeful and ongoing acquisition, interpretation, and synthesis of patient data for clinical decision making." Because nurses are the main staffing constant in the critical care environment, the importance of surveillance as an intervention is fundamental. OBJECTIVE: The aim of this study was to explore how surveillance is expressed by critical care nurses. METHODS: A descriptive exploratory research design was used. Think-aloud was used for data collection. Twenty-one registered nurses from 3 critical care units participated in the study. Participants were asked to say out loud whatever they were thinking as they performed patient care at 3 time points: during handoff, initial patient assessment, and after 4 hours of care. Think-aloud (saying aloud what one is thinking) represents the information (cues) that is attended to in short-term memory, before it has been processed and stored. Data were analyzed using content analysis with key concepts and themes identified. RESULTS: The expression of surveillance was through the main theme of finding meaning. Surveillance involved (a) knowing the patient, (b) shared understanding and decision making, and (c) thinking ahead. The outcomes of these activities were aimed at finding meaning in the cues that emerged as the overarching theme. DISCUSSION: Surveillance was expressed through nurses' gathering cues, reflecting on past knowledge, asking questions, verifying, and pulling it all together to find meaning. During handoff, surveillance involved collaborative cognitive work to find meaning in cues.

Contact tracing with a real-time location system: A case study of increasing relative effectiveness in an emergency department.

BACKGROUND: Contact tracing is the systematic method of identifying individuals potentially exposed to infectious diseases. Electronic medical record (EMR) use for contact tracing is time-consuming and may miss exposed individuals. Real-time location systems (RTLSs) may improve contact identification. Therefore, the relative effectiveness of these 2 contact tracing methodologies were evaluated. METHODS: During a pertussis outbreak in the United States, a retrospective case study was conducted between June 14 and August 31, 2016, to identify the contacts of confirmed pertussis cases, using EMR and RTLS data in the emergency department of a tertiary care medical center. Descriptive statistics and a paired t test (α = 0.05) were performed to compare contacts identified by EMR versus RTLS, as was correlation between pertussis patient length of stay and the number of potential contacts. RESULTS: Nine cases of pertussis presented to the emergency department during the identified time period. RTLS doubled the potential exposure list (P < .01). Length of stay had significant positive correlation with contacts identified by RTLS (ρ = 0.79; P = .01) but not with EMR (ρ = 0.43; P = .25). CONCLUSIONS: RTLS doubled the potential pertussis exposures beyond EMR-based contact identification. Thus, RTLS may be a valuable addition to the practice of contact tracing and infectious disease monitoring.
