Hospital wristband color standardization

Evidence Rating  
Insufficient Evidence
Evidence rating: Insufficient Evidence

Strategies with this rating have limited research documenting effects. These strategies need further research, often with stronger designs, to confirm effects.

Health Factors  
Decision Makers

Color-coded wristbands are visual cues that inform health care providers about hospitalized patients’ circumstances such as elevated fall risk, allergies, or do-not-resuscitate (DNR) status, prompting providers to consult medical records for full details1, 2. Color-coded wristbands are often used as part of a multi-component approach to patient safety. In many hospitals, red signifies allergy, yellow elevated fall risk, and purple DNR status3. Some also use pink to warn of a restricted extremity for blood draws or blood pressures1. However, color codes vary across hospitals4, 5, 6.

Expected Benefits

Our evidence rating is based on the likelihood of achieving these outcomes:

  • Improved patient safety

What does the research say about effectiveness? This strategy is rated insufficient evidence.

There is insufficient evidence to determine whether standardizing the color codes of hospital wristbands improves patient safety. Anecdotal reports suggest that the potential for provider confusion decreases and patient safety increases following standardization of wristband colors1, 7, and a UK-based study suggests that color-coded wristbands that indicate target oxygen range for patients who receive supplemental oxygen can remind providers to monitor oxygen statistics, improving safe prescription of oxygen8. However, wristbands can be difficult to discern at a distance, in low light or when obscured, and can go unnoticed during a crisis; other visible cues may be more noticeable than wristbands in some situations5. Additional evidence is needed to confirm effects.

Experts suggest that providers routinely consult patients’ charts along with wristband cues2 and ensure wristbands are updated as needed to reflect patients’ medical status5.

How could this strategy impact health disparities? This strategy is rated no impact on disparities likely.
Implementation Examples

The Institute for Clinical Systems Improvement (ICSI) and the Agency for Healthcare Research and Quality (AHRQ) multi-component fall prevention efforts are two examples of widely used efforts that include color-coded wristbands. These programs also use signs on patients’ doors and white boards, notes above beds, and color-coded, nonskid socks (yellow for fall risk, red for high fall risk) to indicate fall status9.
