Understanding Design Vulnerabilities in the Physical Environment Relating to Patient Fall Patterns in a Psychiatric Hospital: Seven Years of Sentinel Events

Author(s): Bayramzadeh, S., Portillo, M., Carmel-Gilfilen, C.
​Finding effective ways to prevent patient falls and fall-related injuries has been an ongoing struggle and debate for many modern medical practitioners. Previous studies have shown that nearly 30% of falls that occur in hospital settings result in injuries and, subsequently, additional treatments.

Does the design of settings where acute care is delivered meet the needs of older people? Perspectives of patients, family carers, and staff

Author(s): Haywood, A., Barnes, S., Marsh, H., Parker, S. G.
Acute care for older patients has special requirements but is seldom addressed in relation to the architecture of the facility. Improving the physical environment could result in better health outcomes for a growing number of patients.

Deposition of Bacteria and Bacterial Spores by Bathroom Hot Air Hand Dryers

Author(s): del Carmen Huesca-Espitia, L., Aslanzadeh, J., Feinn, R., Joseph, G., Murray, T. S., Setlow, P.
​Human skin is covered in both pathogenic and non-pathogenic flora, which can be transmitted from surface to surface in a way that may or may not be associated with nosocomial infection. The transmission of microorganisms within healthcare environments presents the possibility of nosocomial infection, especially in the cases of Staphylococcus aureus, enterocci, Pseudomonas spp, Klebsiella spp, and Acinetobacter spp.

The Impact of Operating Room Layout on Circulating Nurse’s Work Patterns and Flow Disruptions: A Behavioral Mapping Study

Author(s): Bayramzadeh, S., Joseph, A., San, D., Khoshkenar, Amin, Taaffe, K., Jafarifiroozabadi, R., Neyens, D. M.
While there are studies focused on the effect that architectural layout, space planning, and adjacencies have on workflow patterns at the unit level, there are few studies at the micro level of individual procedure rooms or surgical suites. The layout of the OR and the placement of equipment may contribute to extraneous and unnecessary movement or create barriers to safety and efficiency, resulting in surgical workflow disruption (SFDs).
