The Impact of Sensory Stimuli on Healthcare Workers and Outcomes in Trauma Rooms: A Focus Group Study.

OBJECTIVE: This study investigated issues related to noise, lighting, and temperature in trauma rooms that impact patient care and staff performance.

BACKGROUND: Uncontrolled sensory stimuli can hinder healthcare delivery quality in trauma rooms. High noise and temperature levels can increase staff stress and discomfort as well as patient discomfort. Conversely, proper lighting can decrease staff stress levels and reduce burnout. Sensory overload in trauma rooms is a crucial concern, but no studies have been conducted on this issue.

METHOD: Using a convenience sampling method, 65 trauma team members (e.g., surgeons, physicians, nurses) from six Level I trauma centers in the United States were recruited to participate in 20 focus groups. Focus groups were semi-structured and 1 hr long.

RESULTS: Staff covered issues related to communications and disruption from noise sources (e.g., equipment, conversations). Having control over lighting allows staff to change light intensity and facilitate their work during the resuscitation. A well-maintained temperature can provide patient comfort or reduce risk of hypothermia, given that patients can lose body heat rapidly due to loss of blood.

CONCLUSION: Excessive sensory stimuli can result in disrupted communication, fatigue, and stress, making staff susceptible to errors. Staffs' control over environmental conditions may lead to a more efficient, comfortable, and safer environment. Technology should be reliable and flexible to facilitate this.
