Can Earplugs and Eye Masks Help ICU Patients Sleep and Stay Clear-Headed? A Brief for the Family Advisory Council

Unit 10 Assignment

Written for a composite ICU's family advisory council, with a cover note to the instructor. Numbers are translated from published reviews.
Cover Note to the Instructor
This brief is written for family members who sit on our unit's advisory council. Every number was translated before use. The relative risk was dropped, because a percentage reduction sounds larger than the change in counts that families can weigh. The pooled estimate from one meta-analysis, a risk ratio near 0.59 with an interval from 0.44 to 0.78 (Litton et al., 2016), was applied to our unit's baseline of about 30 in 100 patients with delirium, giving about 18 in 100, with a plausible range of about 13 to 23. Significance language was removed. The low certainty rating, which matches the Cochrane review's own judgment of the earplug and eye mask evidence (Hu, Jiang, Chen, et al., 2015), became "promising but not settled." The brief reads at about a [seventh]-grade level by my own readability check.
Can Earplugs and Eye Masks Help?
Many patients in intensive care sleep badly. The unit is noisy and bright at night, and poor sleep may add to delirium, a sudden confusion that can frighten patients and families and can slow recovery.
Earplugs and eye masks are a simple way to block some of that noise and light. Researchers have studied them in several hospitals. When their results are put together, the studies suggest they may help.
What the Studies Found
Think of 100 patients like the ones on our unit. Without earplugs and eye masks, about 30 of them would become confused in this way during their stay. With earplugs and eye masks, the studies suggest about 18 would.
That means about 12 fewer people out of 100, but the true number could be as few as 7 fewer or as many as 17 fewer.
Patients who used them also tended to say they slept better. Some patients found them uncomfortable and took them out, and that is fine.
What We Are Not Sure About
The studies were small, and most could not hide from the staff which patients were using the aids. Some of the benefit may have come from other changes hospitals made at the same time. So the result is promising, but it is not settled, and it may turn out smaller on our unit than in the studies.
What the Unit Is Considering
If unit leaders approve, nurses would offer earplugs and an eye mask to patients each night for several months, and the unit would count carefully how many patients become confused, compared with before. Nobody has to use them. Patients can say no, and nurses will take them off for visits, checks and anything else.
What You Might Notice at Night
Your family member may have soft foam earplugs and a light mask over the eyes. If you visit at night, a nurse can remove them so you can talk. If your family member seems upset by them, tell the nurse, and they will be taken out.
Who to Ask
Ask any nurse on the unit, or the unit's nurse educator, [name], at [phone].

How this NU504 Unit 10 example is structured
Every number is translated before it is used, and the brief keeps only what a family could act on. The pooled relative risk is applied to the unit's own baseline and becomes counts out of 100, about 30 against about 18, with the interval rewritten as a range of fewer cases. Significance language is removed entirely, and the low certainty rating becomes promising but not settled. The brief then says what the unit is considering, what families might notice at night and who to ask. The cover note to the instructor justifies each translation and reports the readability check, so the brief can be graded as analysis as well as communication.

NU504 Unit 10 questions, answered
What are natural frequencies, and why use them?
Natural frequencies express risk as counts of people, such as 22 out of 100, instead of percentages, ratios or probabilities. Research on risk communication suggests most readers, including many clinicians, understand counts more accurately than relative figures. Showing both groups' counts side by side lets a reader see the absolute difference without having to calculate it.
How can a confidence interval be explained to people without statistics training?
Describe the range in words and tie it to the same counts used elsewhere. For example, the real difference could be as many as 23 fewer people in 100, or almost zero. Avoid the word confidence, which readers tend to hear as certainty, and say plainly that more research could shift the figure up or down.
Should a dissemination brief mention the study's weaknesses?
Yes, briefly and in plain terms. A family council or staff group deserves to know why the evidence is described as promising rather than proven, for instance that the nurses scoring confusion knew who had used the aids. One or two sentences are usually enough; the aim is honesty about certainty, not a methods critique.
