Question

***** In ICU patients who are 65 or older, how does interrupted sleep (awakened one time or more in four hours) as compared to uninterrupted sleep influence the patient’s cognitive ability over 5 days?

1. Provide a brief description of the topic and background information.
2. Explain the significance of the topic to nursing practice.
3. Provide 3 clearly stated PICOT questions.

Assignment Direction

To formulate questions in Evidence Based Practice, use the PICOT format.

PICOT stands for:

• Population/ Patient Problem: Who is your patient? (Disease or Health status, age, race, sex)
• Intervention: What do you plan to do for the patient? (Specific tests, therapies, medications)
• Comparison: What is the alternative to your plan? (ie. No treatment, different type of treatment, etc.)
• Outcome: What outcome do you seek? (Less symptoms, no symptoms, full health, etc.)
• Time: What is the time frame? (This element is not always included.)

Your PICOT question will fall under one of these types:

• Therapy/Prevention
• Diagnosis
• Etiology
• Prognosis

Answer 1

1)Reasearch has suggested that as well as a good quality sleep as well as quantity sleep greatly influences cognitive ability. A disturbed sleep is associated with an increased risk of developing a cognitive impairments. A good sleep is necessary to feed our high level, innovative thinking and problem solving abilities. As you sleep memories are reactivated, connection between brain cells are strengthened and information is transferred from short to long term. Without enough quality sleep,we can become more forgetful.

2) Sleep deprivation and altered rhythm affects the cognitive performance of the individual.Quality of sleep is comprised in those who are frequently involved in extended working hours and shift work.
Cognitive impairments lead to fatigability, decline in attention and efficiency in work which is found to be more common in nurse's.

3) PICOT QUESTIONS: PICOT stands for
Population/Patient problem.:

- Avoid sleeping during daytime.

Comparison: What is the alternative to your plan?
- Diversion therapy
- drugs to induce sleep

Outcome:What outcome do you seek?
- to get adequate and qualitative sleep
- reduce anxiety
- reduce risk of cognitive impairments

Time:
What is the time frame?
