A review of the research literature on evidence-based healthcare design

Environmental Approaches to Reduce Waterborne Infection Transmission Based on our literature review, the following environmental approaches that aid in controlling and preventing waterborne infections were identified. Technical systems, such as heating, ventilation and air-conditioning, have interrelated design choices and related performance requirements such as energy use, comfort and use cycles are variable components.

Decorative fountains increasingly are being used by designers for healthcare facilities, because they can serve as landmarks and wayfinding elements as well as positive distractions that reduce stress Joseph, Against this background, in the future hospitals may need to screen and assign all inpatients to single rooms upon admission to prevent infections from spreading to other patients.

Use a lifecycle perspective 30—50 years from planning to product, exploring the lifecycle return on investment of design strategies for safety and workforce outcomes. There are some limitations, however, in current hand-washing research knowledge. Now, they can easily call for an assistant without leaving the room.

This underscores the importance of selecting materials that are easily cleaned and of proper cleaning and disinfection procedures Aygun et al. This is adequate for most healthcare settings in ambulatory care facilities and hospitals, including operating rooms ORs Sehulster et al.

Reducing Medical Errors Summary of Evidence and Recommendations Like hospital-acquired infections, medical errors pose serious threats to patient safety.

Environmental Approaches for Reducing Airborne Infections The research literature strongly supports implementing several environmental approaches for controlling and preventing airborne infections, including installing effective filters, specifying appropriate ventilation systems and air change rates, employing various control measures during construction or renovation, and using single-bed rooms instead of multibed rooms to increase isolation capacity and reduce transmission from infected patients.

A limited amount of research has compared different wall finishes and metals with respect to their infection control properties. Anaissie, Penzak, and Dignani reviewed studies between and on waterborne nosocomial infections caused by micro-organisms other than Legionella.

Terminologies Systematic review A systematic review is a summary of the medical literature that uses explicit and reproducible methods to systematically search, critically appraise, and synthesize on a specific issue.

Examples of latent conditions caused by management include work overload, staff shortage, and inexperience with working conditions.

Systematic Reviews and Meta-analysis: Understanding the Best Evidence in Primary Healthcare

Sundstrom and Sundstrom found that visual inspection task performance declined when light is not bright enough.

Another study made a statistical adjustment for other known risk factors of poor hand-washing adherence; the positive effects of the intervention remained significant and were accompanied by decreased infection rates Pettit et al.

Additional research is needed to further confirm the findings of limited previous studies, and to identify ways to design better working environ- ments that may reduce or prevent medical errors. Because infected patients carry airborne pathogens into patient rooms and nursing units, it is important to ensure sufficient isolation capacity for such patients to prevent the spread of pathogens.

The flat-screen monitors, which are attached to the wall opposite the bed, can be used for viewing entertainment as well as health-education programming, such as videos on hip replacement rehabilitation. This report builds on a literature review conducted by researchers in The water supply system should be designed and maintained with proper temperature and adequate pressure; stagnation and back flow should be minimized; and dead-end pipes should be avoid- ed AIA and FGI, ; Sehulster et al.

Based on their type of outcome, following are the measures of outcome: This article has been cited by other articles in PMC. Future research should include prospective controlled experiments, for example, that systematically vary the number and location of alcohol hand-rub dispensers.

In particular, the section on hospital-acquired infections has been substantially revised and expanded, reflecting the rising severity and importance of infections, the rapid growth of infection research, and the appearance of several new studies directly relevant to hospital design.

The higher the percentage weight, the bigger the box, the more influence the study has on the overall results. Contact with nature and daylight [23] has been found to enhance emotional functioning; drawing on research from studies EBD on well-being outcomes and building features.

Effect of single-bed rooms in reducing airborne infection. A systematic review process should follow five steps: A telephone survey of a national sample of U. Decorative fountains increasingly are being used by designers for healthcare facilities, because they can serve as landmarks and wayfinding elements as well as positive distractions that reduce stress Joseph, The difficult and escalating infection control challenge for hospitals that is posed by community-acquired and community-onset infections is reflected, for example, in the fact that MRSA has become the most common cause of skin and soft-tissue infections among patients presenting to EDs in U.

Vinyl upholstery performed the best for VRE—that is, the VRE pathogen survived less well or for shorter periods on vinyl Lankford et al.

Limited research also suggests that patients experience less pain when exposed to higher levels of daylight in contrast to lower levels of daylight in their hospital rooms.

Such poor performance in healthcare settings may lead to medical errors. Are there different approaches to undertaking a literature review. In a study of SARS infections, wards with the highest ventilation rate had a significantly lower infection rate among healthcare workers as compared with other wards Jiang et al.

There is a pattern that compliance is worse in high-acuity units such as ICUs, because patient care in these units is often more demanding than in lower-acuity units Karabay et al.

The Business Case for Patient-Centered Facility Design

There is a pattern across scores of studies indicating that infection rates are lower when there is very good air and water quality, and greater physical separation, isolation, or space per patient. Causes and Locations of Patient Falls Previous studies have examined the locations of fall incidents retrospectively or discussed environmental-modification programs, such as improving lighting, securing carpeting, and so on.

For traditional soap-and-water hand washing, automated sinks or faucets have shown mixed results Larson et al.

The practice and teaching of Evidence-Based Medicine has outcome products which help the health care provider and consumer keep up with the medical literature and assess the evidence.

This secondary literature synthesizes, filters, and evaluates the primary research literature. This report surveys and evaluates the scientific research on evidence-based healthcare design and extracts its implications for designing better and safer hospitals.

Background: It builds on a literature review conducted by researchers in "A review of the research literature on evidence based healthcare design", White Paper Series 5/5, Evidence-Based Design Resources for Healthcare Executives, Center for Health Design, September Further reading [ edit ].

industry looking at is Evidence Based Design (EBD), which promises better healthcare performance through long-run cost reducing facility design innovations. EBD is defined as the use of evidence (credible research) during planning, design, and construction of.

Working with the design research team, the project team settled on the following avenues to support the design: Review the scientific literature. This was done to leverage the large body of EBD information that exists for single-occupancy inpatient rooms.
