Triage Drift: A Workplace Study in a Pediatric Emergency Department

Disentangling the clinical data chaos: User-centered interface system design for trauma centers

This paper presents a year-long study of our project, aiming at (1) understanding the work practices of clinical staff in trauma intensive care units (TICUs) at a trauma center, with respect to their usage of clinical data interface systems, and (2) developing and evaluating an intuitive and user-centered clinical data interface system for their TICU environments. Based on a long-term field study in an urban trauma center that involved observation-, interview-, and survey-based studies to understand our target users and their working environment, we designed and implemented MediSenseView as a working prototype. MediSenseView is a clinical-data interface system, which was developed through the identification of three core challenges of existing interface system use in a trauma care unit-device separation, usage inefficiency, and system immobility-from the perspectives of three staff groups in our target environment (i.e., doctors, clinical nurses and research nurses), and through an iterative design study. The results from our pilot deployment of MediSenseView and a user study performed with 28 trauma center staff members highlight their work efficiency and satisfaction with MediSenseView compared to existing clinical data interface systems in the hospital.

Challenging 'colour time': A practice and narrative approach to organising waiting time in hospitals

Waiting time in hospitals is often studied from one of two perspectives: a distributed resource in hospitals or a potential steering and measuring factor. In this article, waiting time in an emergency department is examined from a practice and a narrative perspective, placing time at the core of our analysis. Our article explores patient waiting time as a local practice that builds on the temporal structuring that affects how waiting time is regulated by both normal clock time and event time-as interpretative time. We also consider how individual narratives in situated spaces allow for negotiations, but we also present isolated time experiences. The empirical data derive from an organisational ethnographic study of a newly introduced triage system for incoming patients at an emergency department in Denmark. The analysis shows how waiting time is organised in the formal visitation system as 'colour time' based on the negotiations of the health-care professional as at the 'right time' and as the patient's individual illness experiences with 'wasting time'. The findings indicate the importance of the unequal relationship between clock time and event time and the different contextual situations affecting the possibilities of organising.

Test results management and distributed cognition in electronic health record-enabled primary care

Managing abnormal test results in primary care involves coordination across various settings. This study identifies how primary care teams manage test results in a large, computerized healthcare system in order to inform health information technology requirements for test results management and other distributed healthcare services. At five US Veterans Health Administration facilities, we interviewed 37 primary care team members, including 16 primary care providers, 12 registered nurses, and 9 licensed practical nurses. We performed content analysis using a distributed cognition approach, identifying patterns of information transmission across people and artifacts (e.g. electronic health records). Results illustrate challenges (e.g. information overload) as well as strategies used to overcome challenges. Various communication paths were used. Some team members served as intermediaries, processing information before relaying it. Artifacts were used as memory aids. Health information technology should address the risks of distributed work by supporting awareness of team and task status for reliable management of results.

Prehospital Application of the Canadian Triage and Acuity Scale by Emergency Medical Services

OBJECTIVES

Triage is fundamental to emergency patient assessment. Effective triage systems accurately prioritize patients and help predict resource utilization. CTAS is a validated five-level triage score utilized in Emergency Departments (EDs) across Canada and internationally. Historically CTAS has been applied by triage nurses in EDs. Observational evidence suggests that the CTAS might be implemented reliably by paramedics in the prehospital setting. This is the first system-wide assessment of CTAS interrater reliability between paramedics and triage nurses during clinical practice.

METHODS

Variables were extracted from hospital and EMS databases. EMS providers determined CTAS on-scene, CTAS pre-transport, and CTAS on-arrival at hospital for each patient (N=14,378). The hospital arrival EMS CTAS (CTAS arrival ) score was compared to the initial nursing CTAS score (CTAS initial ) and the final nursing CTAS score (CTAS final ) incuding nursing overrides. Interrater reliability between ED CTAS initial and EMS CTAS arrival scores was assessed. Interrater reliability between ED CTAS final and EMS CTAS arrival scores, as well as proportion of patient encounters with perfect or near-perfect agreement, were evaluated.

RESULTS

Our primary outcome, interrater reliability [kappa=0.437 (p<0.001, 95% CI 0.421-0.452)], indicated moderate agreement. EMS CTAS arrival and ED CTAS initial scores had an exact or within one point match 84.3% of the time. The secondary interrater reliability outcome between hospital arrival EMS CTAS (CTAS arrival ) score and the final ED triage CTAS score (CTAS final ) showed moderate agreement with kappa =0.452 (p<0.001, 95% CI 0.437-0.466).

CONCLUSIONS

Interrater reliability of CTAS scoring between triage nurses and paramedics was moderate in this system-wide implementation study.

Effects of electronic emergency-department whiteboards on clinicians' time distribution and mental workload

Whiteboards are a central tool at emergency departments. We investigate how the substitution of electronic for dry-erase whiteboards affects emergency department clinicians' mental workload and distribution of their time. With the electronic whiteboard, physicians and nurses spend more of their time in the work areas where other clinicians are present and whiteboard information is permanently displayed, and less in the patient rooms. Main reasons for these changes appear to be that the electronic whiteboard facilitates better timeouts and handovers. Physicians and nurses are, however, in the patient rooms for longer periods at a time, suggesting a more focused patient contact. The physicians' mental workload has increased during timeouts, whereas the nurses' mental workload has decreased at the start of shifts when they form an overview of the emergency department. Finally, the secretaries, but neither physicians nor nurses, access whiteboard information on computers other than the permanent displays.

Coping with the unforeseen in surgical work

OBJECTIVE

The purpose of this study was to investigate how staff working in the perioperative domain copes with unforeseen events and in what way, if at all; they are supported in this by formal systems such as information systems.

DESIGN

Case study. We conducted our study in the Department of Surgery in a large academic hospital in Norway. The department consists of eight operating rooms for planned surgery. The study included observations and interviews, in addition to one design workshop with health personnel. We focused on planned surgery.

RESULTS

Our observations showed that unforeseen events that cause deviations from plans are characteristic and that staff apply different coping strategies to make the plan work regardless. Support of these coping strategies by formal systems is poor.

DISCUSSION

We used the concept of high-reliability organisations as proposed by Weick and Sutcliffe, 2007, to analyse the observed coping strategies. The coping strategies can be seen as examples of the principles for managing the unexpected that Weick and Sutcliffe propose. IT support for this must include both awareness-creating systems and systems that enable workers to control the effects of unforeseen events once they have occurred.
