We shape our buildings and afterwards our buildings shape us... Winston Churchill (May 10, 1941)
Health care facilities encompass a wide range of types, from small and relatively simple medical clinics to large, complex, and costly, teaching and research hospitals. Large hospitals centers may include all the various subsidiary health care types that are often independent facilities. The old expression, "You never get a second chance to make a good first impression" applies to health care facilities. The facility conveys a message to patients, visitors, volunteers, vendors, and staff. The facility also communicates a torrent of clues about the organization and the medical care being provided there. The clues start at the approach to the facility, the drop-off area, the parking lots, and the street signs. Ideally, that message is one that conveys welcoming, caring, comfort, and compassion, commitment to patient well-being and safety, where stress is relieved, refuge is provided, respect is reciprocated, competence is symbolized, way-finding is facilitated, and families are accommodated. The facility also influences employee service attitudes and behaviors. Finishes, signage, and artwork must be carefully selected, well coordinated, and integrated. Security can be balanced with some features apparent to patients/visitors, while conveying a message of safety. Thoughtful design can help ensure the proper first impression is created and sustained.
The design of health care facilities is governed by many regulations and technical requirements. It is also affected by many less defined needs and pressures. The most pressing of these are workforce shortages, reimbursements, malpractice insurance, physician-hospital relations, capacity, care for the uninsured, patient safety, advances in technology, and patient satisfaction per a recent American College of Healthcare Executives survey of hospital CEOs.

The entire health care system is under great pressure to reduce costs, and at the same time, be more responsive to "customers". The aging are the heaviest users of health care services, and the percentage of the aging in our population is increasing significantly. At the same time, rapid technological advances, often involving very sophisticated techniques and equipment, make more diagnostic and treatment procedures available. The consequent increase in health care costs is not easily accommodated. Designers find increasing focus on limiting both construction costs and the costs of their design services, while compressing construction schedules and still meeting the highest quality standards.
As cost pressures increase, health care facilities find themselves in increasing competition for both patients and staff. Architecture is often recognized as an important tool in attracting and retaining the best doctors and nurses, the most successful HMOs and insurance plans, and the most patients. Consumer decisions are based on cost, accessibility, quality of service, and quality of medical care. An aesthetically pleasing facility is a key aspect of the perceived quality of care.
Health care is a labor-intensive industry, and much of that labor is highly skilled and highly paid. Since 60 to 75% of hospital expenses are labor costs, a design that increases operational productivity or efficiency and reduces staffing needs can have a major impact on the bottom line. (Don Blair, then at Perkins + Will, estimated that the cost of one full-time staff person is equivalent to the debt service on $1 million of borrowing per Architectural Record of May 1997.) Likewise, operations and maintenance costs over the typical 50-year life cycle of a hospital contribute up to 80% to the equation, so anything designers can do to facilitate maintenance and reduce total life-cycle cost will have tremendous returns on a relatively small up-front investment.

Flexibility must be a basic feature of any new health care facility to keep it from rapid obsolescence in the face of changing needs and technologies. Health care facility needs are evolving rapidly, and the direction of that evolution is difficult to forecast with any certainty. New equipment technologies, new treatment methodologies, changes in diseases, and changes in the patient population base all impact the facilities that house them. Inpatient care is steadily being reduced while outpatient services are growing. There is increasing emphasis on special-care units and smaller satellite facilities rather than large, centralized facilities.
In the past, communicable diseases were the major health problem, and sanitation or cleanliness was the main characteristic of a healing or therapeutic environment. Cleanliness remains extremely important, but there is increasing recognition of the value of a pleasant, easily-understood, and non-threatening environment for patient recovery. For example, the Planetree Hospital philosophy of "demystifying medicine" emphasizes such a physical environment as part of its approach. Good design in the health care setting starts by recognizing the basic functional needs, but does not end there-it must also meet the emotional needs of those who use such facilities at times of uncertainty, dependency, and stress.
The HIPAA (Health Insurance Portability and Accessibility Act of 1996) regulations address security and privacy of "protected health information" (PHI). These regulations put emphasis on acoustic and visual privacy. While HIPAA does not regulate facilities design, its implications for healthcare facilities may affect location and layout of workstations that handle medical records and other patient information, paper and electronic, as well as patient accommodations.
There is a noticeable movement from hospital-based acute care to outpatient care, and toward a more holistic, preventative, and continuous care of health and wellness.
Sustainability must be a consideration for the design of all health care facilities. Many sustainable design features can be incorporated into health care facility design, including daylighting, energy and water conservation, nontoxic materials and finishes, and sustainable operations and maintenance. Health care facility energy and water conservation standards must meet EPAct 2005 and Executive Order 13693 requirements. The Energy Independence and Security Act of 2007 (EISA) provides additional requirements for energy conservation.
There is an increasing emphasis on security, especially in large public facilities, and the need to balance this with the desired openness to patients and visitors.
Evidence-based design. According to the Center for Health Design, "Evidence-Based Design is the process of basing decisions about the built environment on credible research to achieve the best possible outcomes. Evidence-based health-care architecture creates safe and therapeutic environments for patient care and encourages family involvement. It promotes efficient staff performance and is restorative for workers under stress. These designs ultimately should improve the organization's clinical, economic, productivity, satisfaction, and cultural measures."
A trend towards specialization has resulted in a growing number of health care types. Among them are hospitals, nursing homes, outpatient facilities, psychiatric facilities, rehabilitation facilities, hospices, assisted living facilities, congregate housing, adult day care facilities, and various specialized outpatient facilities. The WBDG currently includes sections on the following four specific building types:
- Nursing Home, including Alzheimer's Related Dementia (ARD) units
- Outpatient Clinic, including the specialized diagnostic and treatment areas which may be stand-alone facilities
- Psychiatric Facility, including psychiatric hospitals
