Behavioral Healthcare Design: Five Key Factors for Patient Well-Being
Our final post on planning and designing of behavioral healthcare facilities will cover the five key factors for patient well-being.
In 2004, “The Role of the Physical Environment in the Hospital for the 21st Century: A Once-in-a-Lifetime Opportunity,” published by Roger Ulrich P.H.D., of Texas A&M University, was released. In a culmination of evidence-based research, research teams found five design principles that contributed significantly to achieving therapeutic design goals.
The report indicates five key factors that are essential for the psychological well-being of patients, families and staff, including:
- Access to Nature
- Provide Positive Distractions
- Provide Social Support Spaces
- Give a Sense of Control
- Reduce or eliminate environmental stress
Access to Nature
Studies indicate that nature might have the most powerful impact to help patient outcomes and staff effectiveness. Nature can be literal or figurative – natural light, water walls, views to nature, large prints of botanicals and geography, materials that indicate nature and most importantly, stimulating color that evokes nature. Several studies strongly support that access to nature such as day-lighting and appropriate colorations can improve health outcomes such as depression, agitation, sleep, circadian rest-activity rhythms, as well as length of stay in demented patients and persons with seasonal affective disorders (SAD).
These and related studies continue to affirm the powerful impact of natural elements on patient recovery and stress reduction. Thus, it is clear that interior designs which integrate natural elements can create a more relaxing, therapeutic environment that benefits both patients and staff.
These are a small set of environmental features that provide the patient and family a positive diversion from “the difficult” and, in doing so, also negate an institutional feel. These can be views to nature, water walls, artwork, super imposed graphics, sculpture, music – and ideally all of these want to be focused on nature and, when applicable, an interesting use of color. Therapeutic environments that provide such patient-centered features can empower patients and families, but also increase their confidence in the facility and staff. This helps with open lines of communication between patient and caregiver.
Social Support Spaces
These are spaces designed partially for the patient but mainly for the comfort and socialization of family members and friends of the patient; therefore, family lounges, resource libraries, chapels, sleep rooms and consult rooms all play a role. When family and friends play a key role in a patient’s healing, these spaces encourage families to play an active role in the rehabilitation process.
Sense of Control
In times when patients and family feel out of control, it is very healing for the facility design and staff to provide it back when appropriate. Although, this cannot always be done suitably in mental healthcare facilities. However, when applicable, these design features include optional lighting choices, architectural way-finding, resource libraries, enhanced food menus, private patient rooms and optional areas to reside in. A few well-appointed studies in psychiatric wards and nursing homes have found that optional choices of moveable seating in dining areas enhanced social interaction and improved eating disorders. When patients feel partially in control of their healing program and that the building features are focused to them, an increased confidence of the quality of care enters and tensions lower.
As with all therapeutic design, this allows the caregiver to use their resources healing in lieu of “managing” patient populations.
Reduce or Eliminate Environmental Stress
Noise level measurements show that hospital wards can be excessively noisy places resulting in negative effects on patient outcomes. The continuous background noise produced by medical equipment and staff voices often exceeds the level of a busy restaurant. Peak noise periods (shift changes, equipment alarms, paging systems, telephones, bedrails, trolleys, and certain medical equipment like portable xray machines are comparable to walking next to a busy highway when a motorcycle or large truck passes.
Several studies have focused on infants in NIC Us, finding that higher noise levels, for example, decrease oxygen saturation (increasing need for oxygen support therapy), elevate blood pressure, increase heart and respiration rate, and worsen sleep. Research on adults and children show that noise is a major cause of awakening and sleep loss.
In addition to worsening sleep, there is strong evidence that noise increases stress in adult patients, for example, heightening blood pressure and heart rate. Environmental surfaces in hospitals are usually hard and sound-reflecting, not sound-absorbing causing noise to travel down corridors and into patient rooms. Sounds tend to echo, overlap and linger longer.
Interventions that reduce noise have been found to improve sleep and reduce patient stress. Of these, the environmental or design interventions such as changing to sound-absorbing ceiling tiles, are more successful than organizational interventions like establishing “quiet hours.”
