The Intensive Care Unit (ICU) is an information intense environment where Clinical Information Systems (CISs) can greatly impact patient care and the workload of clinicians. With the introduction of an ICU CIS imminent across New South Wales hospitals, we aimed to understand how ICU clinicians perceived a new system would impact on work practices in Australian ICUs, as much of the current evidence is generated from overseas. We conducted interviews with 66 doctors and nurses in 3 ICUs without a CIS. Many had positive perceptions regarding the impact of its introduction, though others were more guarded and unsure. Clinicians believed information access to patient would improve, communication processes could potentially change and there was potential for work processes to be more efficient. It was expected that ward rounds and handover would be less disrupted with all information available at the bedside or at the handover setting. There were mixed responses about whether a CIS would save time and how it would influence patient care, though the majority believed a CIS would improve safety by providing a means for increasing accountability and reducing medication errors. Concerns were raised about the transition from paper to a CIS and the training required. This information provides valuable evidence in the Australian setting regarding clinicians' expectations of a new ICU CIS to assist with future implementations. It also provides baseline data as a foundation for future research once the CIS is implemented. It is clear that robust quantitative studies are required to gain a detailed understanding of how a new CIS will impact clinicians' work processes and that appropriate training is crucial for full benefits to be achieved.

Picture Archiving and Communication Systems (PACS) allow the fast delivery of imaging studies to clinicians at the point-of-care, supporting quicker decision-making. PACS has the potential to have a significant impact in the Intensive Care Unit (ICU) where critical decisions are made on a daily basis, particularly during ward rounds. We aimed to examine how accessing image information is integrated into ward rounds and if the presence of PACS produced innovations in ward round practices. We observed ward rounds and conducted interviews with ICU doctors at three hospitals with differing levels of PACS availability and computerization. Imaging results were infrequently viewed by clinicians during ward rounds in two ICUs: one without PACS and one which had both PACS and bedside computers. In the third ICU, where PACS was only available at a central workstation, images were frequently viewed throughout the daily round and integrated into decisions about patient care. The presence of bedside computers does not automatically result in innovations to work practice. Despite the ability to utilize PACS at the bedside to support decision-making, use was varied. Research to understand how the complexities and context of the ICU contribute to work practice innovation and why practice changes differ is required.

Doctors are the main users of x-rays and other medical images in hospitals and as such picture archive and communication systems (PACS) have been designed to improve their work processes and clinical care by providing them with faster access to images. Nurses working in intensive care units (ICUs) also access images as an integral part of their work, yet no studies have examined the impact of PACS on the work of intensive care nurses. Our study aimed to examine whether and how ICU nurses view and use images and whether access to PACS promotes innovation in work practices. We interviewed (n=49) and observed (n=23) nurses in three Australian metropolitan teaching hospital ICUs with varying degrees of PACS implementation. Our study found that nurses with access to PACS were able to independently and easily access images, did so more frequently when required, and perceived that this had the potential to positively impact upon patient safety. Those without PACS usually viewed images more traditionally as part of a ward round. The introduction of PACS to ICU settings promotes changes in nursing work practices by providing nurses with the ability to act more autonomously, with the potential to enhance patient care.

Emergency departments (EDs) are high pressure health care settings involving complex interactions between staff members in providing and organising patient care. Without good communication and cooperation amongst members of the ED team, quality of care is at risk. This study examined the problem-solving, medication advice-seeking and socialising networks of staff working in an Australian hospital ED.
