Perceptual Effects of Physical and Visual Accessibilities in Intensive Care Units: A Quasi-experimental Study.

This article reports the findings of a 2-phase quasi-experimental study looking at the perceptual effects of physical and visual accessibilities on clinical staff in intensive care units (ICUs). In a previous CCNQ article by Rashid et al, the first phase of the study was reported comparing, among other things, physical and visual accessibilities and their associations with staff perception in 2 ICUs with the open-plan and racetrack-type layouts. The data for that phase of the study were collected in December 2014, which included the data on physical and visual accessibilities collected using the spatial analysis techniques of Space Syntax, and the data on staff perception collected using a questionnaire survey.

Evaluating Nurses' Perception of Patient Safety Design Features in Intensive Care Units.

A methodological study was conducted to test the validity and reliability of the patient safety (PS) scale developed by Rashid (2007) for evaluating nurses' perception of adult intensive care unit (ICU) design features related to patient safety. Data for the study were collected using a Web-based survey instrument. A link to the survey instrument was posted on the Web site of American Association of Critical-Care Nurses (AACN) for ICU nurses in different US states to participate.

Physical and Visual Accessibilities in Intensive Care Units: A Comparative Study of Open-Plan and Racetrack Units.

This study compared physical and visual accessibilities and their associations with staff perception and interaction behaviors in 2 intensive care units (ICUs) with open-plan and racetrack layouts. For the study, physical and visual accessibilities were measured using the spatial analysis techniques of Space Syntax. Data on staff perception were collected from 81 clinicians using a questionnaire survey.

Network of spaces and interaction-related behaviors in adult intensive care units.

Using three spatial network measures of "space syntax", this correlational study describes four interaction-related behaviors among three groups of users in relation to visibility and accessibility of spaces in four adult intensive care units (ICUs) of different size, geometry, and specialty. Systematic field observations of interaction-related behaviors show significant differences in spatial distribution of interaction-related behaviors in the ICUs. Despite differences in unit characteristics and interaction-related behaviors, the study finds that when nurses and physicians "interact while sitting" they prefer spaces that help maintain a high level of environmental awareness; that when nurses "walk" and "interact while walking" they avoid spaces with better global access and visibility; and that everyone in ICUs "walk" more in spaces with higher control over neighboring spaces.

Developing nurse and physician questionnaires to assess primary work areas in intensive care units.

The objective of the study was to develop instruments for describing and assessing some aspects of design of the primary work areas of nurses and physicians in intensive care units (ICUs). Separate questionnaires for ICU physicians and nurses were developed. Items related to individual- and unit-level design features of the primary work areas of nurses and physicians were organized using constructs found in the literature.

Space Allocation in the Award-Winning Adult ICUs of the Last Two Decades (1993-2012): An Exploratory Study.

Objective: This exploratory study describes space allocation among different generic categories of functions in adult intensive care units (ICUs) showing how the amount of space of any one functional category is related to that of another functional category, and how different strategic choices, such as size, construction type, specialty type, and layout type, affect space allocation in these ICUs.

Background: Even though critical care practice has already undergone significant changes in the last few decades, it is still an evolving domain of medical practice. As a result, ICU design is also evolving as new regulatory standards, new technologies, and new clinical models are being introduced.

Two decades (1993-2012) of adult intensive care unit design: a comparative study of the physical design features of the best practice examples.

In 2006, Critical Care Nursing Quarterly published a study of the physical design features of a set of best practice example adult intensive care units (ICUs). These adult ICUs were awarded between 1993 and 2003 by the Society of Critical Care Medicine (SCCM), the American Association of Critical-Care Nurses, and the American Institute of Architects/Academy of Architecture for Health for their efforts to promote the critical care unit environment through design. Since 2003, several more adult ICUs were awarded by the same organizations for similar efforts.

The question of knowledge in evidence-based design for healthcare facilities: limitations and suggestions.

Objective: To help designers and researchers and other proponents of evidence-based design (EBD) overcome limitations concerning knowledge categorization and acquisition of evidence-based design (EBD).

Background: The evidence-based design (EBD) approach for healthcare facilities has been widely embraced by both designers and researchers in recent years; however, there are some limitations concerning knowledge categorization and acquisition of EBD. These limitations include an overemphasis on empirical knowledge gained by experimental research, a narrow focus that excludes design knowledge generated outside healthcare and allied fields, and a lack of interest in empirical knowledge gained by qualitative studies.

Development and reliability testing of a self-report instrument to measure the office layout as a correlate of occupational sitting.

Background: Spatial configurations of office environments assessed by Space Syntax methodologies are related to employee movement patterns. These methods require analysis of floors plans which are not readily available in large population-based studies or otherwise unavailable. Therefore a self-report instrument to assess spatial configurations of office environments using four scales was developed.

Technology and the future of intensive care unit design.

Changing market demand, aging population, severity of illnesses, hospital acquired infection, clinical staff shortage, technological innovations, and environmental concerns-all are shaping the critical care practice in the United States today. However, how these will shape intensive care unit (ICU) design in the coming decade is anybody's guess. In a graduate architecture studio of a research university, students were asked to envision the ICU of the future while responding to the changing needs of the critical care practice through innovative technological means.

Hospital design and face-to-face interaction among clinicians: a theoretical model.

A growing body of literature suggests that face-to-face interaction among clinicians in hospitals affects patient outcomes. How can face-to-face interaction among clinicians be influenced positively to improve patient outcomes in hospitals? So far, most strategies for improving face-to-face interaction in hospitals have focused on changing organizational culture. In contrast, this paper proposes a theoretical model that shows how spatial program and structure can help face-to-face interaction fulfill its purposes in hospitals by controlling the interfaces among different communities of clinicians.

The architecture of safety: hospital design.

Purpose Of Review: This paper reviews recent research literature reporting the effects of hospital design on patient safety.

Recent Findings: Features of hospital design that are linked to patient safety in the literature include noise, air quality, lighting conditions, patient room design, unit layout, and several other interior design features. Some of these features act as latent conditions for adverse events, and impact safety outcomes directly and indirectly by impacting staff working conditions.

Developing scales to evaluate staff perception of the effects of the physical environment on patient comfort, patient safety, patient privacy, family integration with patient care, and staff working conditions in adult intensive care units: a pilot study.

Studies suggest that the physical environment can be important for patient comfort, patient safety, patient privacy, family integration with patient care, and staff working condition in adult intensive care units (ICUs). In the absence of any measuring scales, however, evaluations of the physical environment of ICUs in terms of any of these dimensions have remained vague. For rigorous evaluations of ICU designs from the viewpoint of clinical staff, a self-report instrument with several multiple-item scales was created.

A decade of adult intensive care unit design: a study of the physical design features of the best-practice examples.

This article reports a study of the physical design characteristics of a set of adult intensive care units (ICUs), built between 1993 and 2003. These ICUs were recognized as the best-practice examples by the Society of Critical Care Medicine, the American Association of Critical Care Nurses, and the American Institute of Architects. This study is based on a systematic analysis of the materials found on these ICUs in the booklet and videos jointly published by the above organizations in 2005.
