Patient Safety in the Cardiac Operating Room: Human Factors and Teamwork A Scientific Statement From the American Heart Association

Author(s): Wahr, J. A., Prager, R. L., Abernathy, J. H., Martinez, E. A., Salas, E., Seifert, P. C., Groom, R. C., Spiess, B. D., Searles, B. E., Sundt, T. M., Sanchez, J. A., Shappell, S. A., Culig, M. H., Lazzara, E. H., Fitzgerald, D. C., Thourani, V. H., Eghtesady, P., Ikonomidis, J. S., England, M. R., Sellke, F. W., Nussmeier, N. A.
The cardiac surgical operating room is a complex environment, where patient lives are saved or considerably improved with the help of sophisticated equipment and skilled personnel. Although outcomes are improving, adverse events still occur, many of which are preventable. This statement is the result of a review of literature that presented evidence on patient safety and interventions that worked in enhancing patient safety in the cardiac OR.

Do absorption and realistic distraction influence performance of component task surgical procedure?

Author(s): Pluyter, J. R., Buzink, S. N., Rutkowski, A. F., Jakimowicz, J. J.
Surgeons’ ability of focusing their attention on surgical tasks directly impacts their performance on surgical operations, which is an important factor influencing quality of care, work efficiency, patient satisfaction, and many other healthcare outcomes. Attention or concentration is more important for performing minimal invasive surgeries which involve complex technologies and put high physical and cognitive demands on surgeons.

Factors Affecting Acoustics and Speech Intelligibility in the Operating Room: Size Matters

Author(s): McNeer, R. R., Bennett, C. L., Horn, D. B., Dudaryk, R.
Previous studies have shown that noise levels within healthcare environments have been increasing steadily since 1960. Noise is a prominent source of discomfort for both patients and staff, and can also interfere with important interpersonal communications.

Centralized vs. Decentralized Nursing Stations: Effects on Nurses’ Functional Use of Space and Work Environment

Author(s): Zborowsky, T., Bunker Hellmich, L., Morelli, A., O’Neill, M.
Information technology enables nurses to move away from traditional centralized paper-charting stations to smaller decentralized work stations and charting substations located closer to, or inside of, patient rooms. Understanding the tradeoffs presented by centralized and decentralized nursing station design could provide useful information for future design and the nurse environment "fit."

Effect of noise on auditory processing in the operating room

Author(s): Way, T. J., Long, A., Weihing, J., Ritchie, R., Jones, R., Bush, M., Shinn, J. B.
Noise in operating rooms (ORs), defined as any unwanted sound impeding on normal hearing, can be grouped into two categories: equipment-related noise and staff-created noise. Equipment-related noise can come from anesthesia equipment and alarms, suction devices, or surgical instruments such as cautery devices, dissection tools, and drills. Staff-created noise can come from opening and closing doors, conversations, overhead pages, and music. All of these noise sources contribute to the average ambient noise in ORs, which is 65 dBA with peak levels reaching120 dBA.

Impact of the Design of Neonatal Intensive Care Units on Neonates, Staff, and Families: A Systematic Literature Review

Author(s): Shahheidari, M., Homer, C.
The authors indicate that the design of NICUs incorporating single family rooms as evidence indicates this room type contributes to the better development of babies, facilitates increased parental involvement in care, controls infection, and reduces noise and length of stay.

Objective acoustical quality in healthcare office facilities

Author(s): Hodgson, M.
In this relatively brief study, the author chooses to survey a number of different healthcare offices in different locations in order to describe their acoustical nature and identify how certain design elements affect acoustical properties. Many different aspects of the offices’ physical design are taken into account in order to produce a comprehensive analysis of what exactly affects a given environment’s acoustical characteristics, and what could potentially be done to improve these characteristics.

Music increases satisfaction in elderly outpatients undergoing cataract surgery

Author(s): Cruise, C. J., Chung, F., Yogendran, S., Little, D.
Cataract surgery is one of the most common surgical procedures performed on elderly patients in North America. Sedative medications are often used to reduce patient anxiety throughout the surgical procedure, but elderly patients are more likely to experience adverse health effects from these medications. The anxiety-reducing effects of music have been widely studied previously, but never in the context of elderly patients undergoing cataract surgery.
