Input: Overall, 102 studies have been included in this review. Interventions explored were: 'positive distracters', to include aromas (two studies), audiovisual distractions (five studies), decoration (one study), and music (85 studies); interventions to reduce environmental stressors through physical changes, to include air quality (three studies), bedroom type (one study), flooring (two studies), furniture and furnishings (one study), lighting (one study), and temperature (one study); and multifaceted interventions (two studies). We did not find any studies meeting the inclusion criteria to evaluate: art, access to nature for example, through hospital gardens, atriums, flowers, and plants, ceilings, interventions to reduce hospital noise, patient controls, technologies, way-finding aids, or the provision of windows. Overall, it appears that music may improve patient-reported outcomes such as anxiety; however, the benefit for physiological outcomes, and medication consumption has less support. There are few studies to support or refute the implementation of physical changes, and except for air quality, the included studies demonstrated that physical changes to the hospital environment at least did no harm. Music may improve patient-reported outcomes in certain circumstances, so support for this relatively inexpensive intervention may be justified. For some environmental interventions, well designed research studies have yet to take place.
Output:

The review identified 102 relevant studies, 85 of which were on the use of music in hospital. Other environmental aspects considered were: aromas (two studies), audiovisual distractions (five studies), decoration (one study), air quality (three studies), bedroom type (one study), flooring (two studies), furniture and furnishings (one study), lighting (one study), temperature (one study), and multiple design changes (two studies). No studies meeting the inclusion criteria were found to evaluate: art, access to nature for example through hospital gardens, atriums, flowers, and plants, ceilings, interventions to reduce hospital noise, patient controls, technologies, way-finding aids, or the provision of windows. Overall, it appears that music in hospital may help improve patient-reported outcomes such as anxiety; however, there is less evidence to support the use of music for physiological outcomes (such as reducing heart rate and blood pressure) and for reducing the use of medications. For other aspects of hospital environments, there are not very many well designed studies to help with making evidence-based design decisions. The studies that have been included in this review show that physical changes made to 'improve' the hospital environment on the whole do no harm.
