A study of room acoustics and the nature of sound for the quality of work, comfort and patient care in coronary critical care. Medical care is a profession that makes tremendous physical and emotional demands on the staff. This presentation is part of a project that deals with the effects of the acoustic environment on the work and the patients in a hospital ward. The contents are based on a scientific study carried out at the National Institute for Psychosocial Medicine (IPM) together with the Department of Cardiology, Karolinska University Hospital (Huddinge), Stockholm and the Center for Health...

The quality of care and medical results as final product There is a clear connection between the physical environment and the conditions available for the medical staff to do a good job. By comparing the differences arrived at in the study we have a better understanding of how the acoustic environment affects us at work. An insight into and knowledge of this connection is a basic premise for being When the workload feels reasonable able to create a tenable environment for both and the surroundings facilitate the planned the patients and the staff. work pattern, the atmosphere in the workplace...

Earlier studies have shown that certain Sick or healthy, we are all affected by our healthcare environments are significantly physical surroundings. When our bodily noisier than others and this can also be seen functions are impaired we are more sensitive in the opinions of the staff. In particular the to heat, sound and light. This is an important acoustic environment in intensive care has been component for recovery in health care. Annoying associated with noise levels that are perceived noises on a ward where patients are being as annoying and tiring for both patients and treated for life-threatening...

Acoustic Design for Health is based on a study of the acoustic environment of a Coronary Critical Care Unit (CCU), the project Acoustics, the Working Environment and Health. The scientific investigation behind the study was carried out by the Institute for Psychosocial Medicine (IPM) at, and together with, the Department of Cardiology at Karolinska University Hospital (Huddinge) and the Center for Health Systems and Design at Texas A&M University. A complete account of the study can be found in the scientific publications resulting from the project, see Reference list. To carry out a comparative...

Reverberation time halved and a sound reduction of 6 decibels Acoustic measurements confirmed that the reverberation time in the central part of the unit changed from 0.8 seconds with a ceiling that reflected sound to 0.4 seconds with one that absorbed sound. The patients rooms had a slightly longer reverberation time, 0.9 seconds, but had the same reverberation time as the rest of the unit after rebuilding. The change also affected the sound level in the unit. Depending on the point of measurement, the difference between the two was up to 6 dB. The daily average of the sound level in the patientsҒ...

The staff perceived the pace and amount of work as greater when the acoustic environment was bad. This, despite the fact that there were fewer patients to look after than in the other period. They also felt that the atmosphere in the unit was worse and that the staff irritated one another more. Altogether this had a negative effect on the quality of the work. In other words, good patient care suffered. > Demand Index The result of the questions > Change in the perception of demands during the working day about the working situation in the > � questionnaire was summarised in an index that described...

Good working atmosphere and quieter environment - reduction in the need for aftercare For the patients that were most seriously ill (diagnosed acute myocardial infarction and unstable angina pectoris) there was a difference in objective stress levels between the two study periods. This was determined by measuring the pulse amplitude, a physiological stress marker. For these patients a higher pulse amplitude was recorded during the night, which indicates that these patients found the environment more stressful when the acoustic conditions were bad. Patients who were treated during the period with...
