Brief Summary:
  • Rationale: Recently, research that demonstrates a clear relationship between the built healthcare environment and the health and wellbeing of patients has come available. Patients in a CT scan suite are usually anxious. The environment has been shown to lower stress; a painting or piece of art for example, can capture and hold attention and thereby lower negative thoughts and evoke positive emotions. Sights of nature have demonstrated to be especially effective in recuperating from stress, presumably because the human brain has evolved in a natural environment. The current study will investigate the effects of exposure to nature in the CT scan suite. A SkyCeiling, a large, slightly illuminated, photographic illusion of a real sky view is placed above the CT scan. The main hypothesis of this study is that a sky view will lead to a lower level of anxiety in the CT scan suite.
  • Objective: The primary objective of this study is to examine the effect of a view of nature on a patient's stress and anxiety. Secondary objectives are to study the effects of a view of nature on a patient's environmental appraisals of the CT suite, satisfaction with the provided service, and trust in the healthcare provider.

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
120 Out-patients, age 18-85, who are scheduled to undergo a thorax and/or abdomen CT scan with intravenous contrast.

Inclusion Criteria:

  • Age 18-85
  • Able to read and write Dutch
  • Able to observe the visual stimuli applied to the ceiling, i.e. normal vision or corrected to normal vision.

Exclusion Criteria:

  • Patients who have undergone a CT scan after the SkyCeiling was installed (this is a rare event) are excluded. This because of the fact that these patients might remember the look of the CT unit either with or without the SkyCeiling and could thus become more aware of the intended anxiety-reducing effect of the intervention, or the lack thereof if randomized to the control group.
  • Patients who undergo a second scan during the run time of this study (this will be a rare event) will not be included a second time. The data of their first scan remain included.
  • Patients who lie with their face down or are otherwise incapable of looking at the ceiling will be excluded.
