Patient Outcomes and Safety Flashcards

Which design feature has the strongest EBD evidence for directly reducing patient falls?

Answer: Single-patient rooms with bathrooms located close to the bed

Rooms with adjacent bathrooms reduce the distance patients must travel unsupported, which is the leading situational factor in patient falls.

How does natural light exposure in patient rooms most directly affect health outcomes according to EBD?

Answer: It regulates circadian rhythms, improving sleep quality and reducing length of stay

Natural light synchronizes the body's circadian clock, improving sleep, reducing depression, and correlating with shorter hospital stays.

EBD evidence most strongly links reduced healthcare-associated infection rates to:

Answer: Private single-patient rooms with dedicated toileting facilities

Private rooms with dedicated bathrooms prevent pathogen cross-transmission between patients, which is a primary source of HAIs.

Which patient outcome is most strongly and directly improved by reducing hospital noise levels?

Answer: Sleep quality and duration

Noise is the single most commonly cited disruptor of patient sleep in hospitals; reducing it directly improves sleep duration and quality.

According to EBD research, which design element most effectively reduces nurse medication errors?

Answer: Dedicated, enclosed medication preparation rooms that minimize interruptions

Interruption during medication preparation is a leading cause of errors; dedicated rooms physically shield nurses from interruptions.

How does patient room standardization improve safety outcomes in EBD practice?

Answer: Consistent layouts allow staff to locate equipment quickly, reducing errors from unfamiliarity

When rooms are identical, staff do not need to reorient in each room, reducing the cognitive errors that arise from variable layouts.
