A Comparative Study of Design Strategies for Lobby of Outpatient Department of Hospital Buildings in Cold Climate Region in China

Relationship between Environmental Conditions and Nosocomial Infection Rates in Intensive Care Unit

Author(s): Şimşek, E. M., Grassie, S. S., Emre, C., Gevrek, S. Ç.
Due to the highly vulnerable state of the patients populating intensive care units (ICUs) and the health risks posed to healthcare providers working in ICUs, special attention must be given to the causes and effects of nosocomial infections within these areas.

Methodology for analyzing environmental quality indicators in a dynamic operating room environment

Author(s): Gormley, T., Markel, T. A., Jones, H. W., Wagner, J., Greeley, D., Clarke, J. H., Abkowitz, M., Ostojic, J.
Operating rooms (ORs) provide space for delicate and complex medical procedures. This is why these spaces are closely monitored for cleanliness and efficiency. HVAC (heating, ventilation and air conditioning) are especially important features to optimize in these environments so that rates of surgical site infections may be reduced.

The impact of patient room design on airborne hospital-acquired infections

Bed-integrated local exhaust ventilation system combined with local air cleaning for improved IAQ in hospital patient rooms

Author(s): Bivolarova, M. P., Melikov, A. K., Mizutani, C., Kajiwara, K., Bolashikov, Z. D.
Ventilation in patient rooms can contribute to the health and comfort of both patients and staff. Indoor air quality (IAQ) is indeed an important factor in healthcare environments, especially when it comes to mitigating the spread of germs and potentially toxic airborne chemicals. Ventilated mattresses (VMs) can be effective for capturing and removing potentially harmful airborne particles before they spread throughout a given space.

The Creation of a Biocontainment Unit at a Tertiary Care Hospital: The Johns Hopkins Medicine Experience

Author(s): Garibaldi, B. T., Kelen, G. D., Brower, R. G., Bova, G., Ernst, N., Reimers, M., Langlotz, R., Gimburg, A., Iati, M., Smith, C., MacConnell, S., James, H., Lewin, J. J., Trexler, P., Black, M. A., Lynch, C., Clarke, W., Marzinke, M. A., Sokoll, L. J., Carroll, K. C., Parish, N. M., Dionne, K., Biddison, E. L. D., Gwon, H. S., Sauer, L., Hill, P., Newton, S. M., Garrett, M. R., Miller, R. G., Perl, T. M., Maragakis, L. L.
Prior to the 2014 Ebola virus disease (EVD) outbreak in West Africa, the United States had only one to three specialized biocontainment units. Once the EVD crisis began, a group of reputable American healthcare institutions worked together to renovate a deactivated clinical space into a functioning biocontainment unit (BCU).

Secondary exposure risks to patients in an airborne isolation room: Implications for anteroom design

Author(s): Mousavi, E. S., Grosskopf, K. R.
Previous research has shown that negatively pressurized Airborne Infectious Isolation Rooms (AIIRs) can protect hospitals from fatal airborne pathogens such as tuberculosis. But this use of negative pressurization can simultaneously increase the chances of isolated patients contracting secondary infections, or healthcare-acquired infections (HAIs), caused by air blowing in from adjacent spaces. Research is needed to better assess the actual likelihood of secondary infections occurring in these scenarios so that steps can be taken to mitigate these risks.

Airflow patterns through single hinged and sliding doors in hospital isolation rooms – Effect of ventilation, flow differential and passage

Author(s): Kalliomäki, p., Saarinen, P., Tang, J. W., Koskela, h.
Patients with highly contagious diseases are often housed in negative pressure isolation rooms. These rooms attempt to reduce cross-infections within the hospital. However, airflows produced by healthcare worker movements and door opening motions pose the risk of spreading pathogen-laden air from negative pressure isolation rooms into other spaces. A significant number of previous studies have examined the impact of single-hinged door-generated airflows, but few have compared hinged doors with sliding doors.

Part 1: Evidence-Based Facility Design Using Transforming Care at the Bedside Principles

Author(s): Devine, D. A., Wenger, B., Krugman, M., Zwink, J. E., Shiskowsky, K., Hagman, J., Limon, S., Sanders, C., Reeves, C.
A western academic hospital reexamined its design strategy when after three years of building a new facility they had to plan for a new facility to meet their patient capacity. Using a combination of the principles of Transforming Care at the Bedside (TCAB) and Evidence-Based Design (EBD), an interdisciplinary team presented design recommendations.
