Purpose: The aim of this article is to provide a case study example of the preopening phase of an interventional trauma operating room (ITOR) using systems-focused simulation and human factor evaluations for healthcare environment commissioning. Background: Systems-focused simulation, underpinned by human factors science, is increasingly being used as a quality improvement tool to test and evaluate healthcare spaces with the stakeholders that use them. Purposeful real-to-life simulated events are rehearsed to allow healthcare teams opportunity to identify what is working well and what needs improvement within the work system such as tasks, environments, and processes that support the delivery of healthcare services. This project highlights salient evaluation objectives and methods used within the clinical commissioning phase of one of the first ITORs in Canada. Methods: A multistaged evaluation project to support clinical commissioning was facilitated engaging 24 stakeholder groups. Key evaluation objectives highlighted include the evaluation of two transport routes, switching of operating room (OR) tabletops, the use of the C-arm, and timely access to lead in the OR. Multiple evaluation methods were used including observation, debriefing, time-based metrics, distance wheel metrics, equipment adjustment counts, and other transport route considerations. Results: The evaluation resulted in several types of data that allowed for informed decision making for the most effective, efficient, and safest transport route for an exsanguinating trauma patient and healthcare team; improved efficiencies in use of the C-arm, significantly reduced the time to access lead; and uncovered a new process for switching OR tabletop due to safety threats identified.

This quality improvement study focused on developing an understanding of factors influencing the ability of prenatal genetics counsellors (GCs) to efficiently see patients during the COVID-19 pandemic and strategies to improve their workflow using techniques from human factors and design. The demand for Prenatal Genetics Clinics is rising which has increased pressure on GCs to become more efficient. Genetics counsellors can improve access to their services by reducing the time spent on the tasks performed before and after a genetic counselling encounter, thereby increasing the number of patients they see. We were limited to certain methods to understand the differences in workflow before and during the COVID-19 pandemic. This study involved a literature review, archival analysis of workflow studies conducted before the pandemic, stakeholder meetings and mapping, a brainstorming session, as well as documenting time-on-task in a diary and naturalistic observation sessions. A task analysis was developed to identify factors influencing efficiency related to the design of the space, processes and the use of artefacts. Virtual and on-site workflows show that GCs spend at least half of their time on tasks before and/or after the patient’s appointment. Looking at potential inefficiencies or bottlenecks in workflow formed the development of a strategic plan for improving GC workflows at the prenatal Genetics Clinic. Improvements suggested through this analysis were constrained to support the current number of healthcare providers working within the existing space configuration.

As the use of surveillance video at commercial properties becomes more prevalent, it is more likely an incident involving a personal injury will be captured on film. This provides a unique opportunity for Human Factors practitioners involved in forensic investigations to analyze the behavior of the individual prior to, during, and after the event in question. It also provides an opportunity to gather unique and objective data. The present work describes a case study of a slip and fall where surveillance video and onsite measurements were combined and analyzed to quantify a plaintiff’s gait pattern. Using this type of analysis, we were able to determine that the plaintiff was likely aware that the floor was slippery and adjusted her gait and behavior prior to the slip and fall incident.

A survey was made of the braking techniques reportedly used by 180 motorcyclists in a variety of conditions. Overall, the motorcyclists indicated that they used both front and rear brakes in hard braking 75% of the time on dry pavement and 47% on wet, but in other conditions they mostly used the rear brake first or exclusively. That the rear brake is preferred is not surprising because of the design of the brake controls and other reasons. Reliance on the rear brake at the expense of the front wheel brake leads to reduced deceleration. A crash case study exemplifies the effect. Integrated brakes, in which each brake control simultaneously activates the brakes on the front and rear wheels, are indicated by good human factors design and by motorcyclist's braking performance and should improve safety, especially when the brakes incorporate anti-locking mechanisms
