The Effect of the Use of Gel Pillows on the Sleep Quality and General Comfort Levels

May 9, 2025 updated by: Seher Ünver, Trakya University

The Effect of the Use of Gel Pillows on the Sleep Quality and General Comfort Levels of the Patients in the Preoperative Period

The study was conducted to evaluate the effect of using gel pillows on the sleep quality and general comfort levels of patients in the preoperative period.The main hypotheses are:

H1: 'The sleep quality of patients who use gel pillows in the preoperative period is higher than those who do not use gel pillows' H2: "The general comfort level of the patients who used gel pillows in the preoperative period is higher than those who did not use gel pillows".

Participants will be asked to use a gel pillow with a cooling surface the night before the day of surgery.

If there is a comparison group: Researchers will compare patients' control group to see if there is any difference in sleep quality and comfort levels.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Randomization method will be used to determine the groups. Randomization of the patients was done using the 'Random Allocation Software 2.0' program and they are allocated into 2 groups: 1) the control group and 2) the intervenion group.

  1. The Control Group: The patients in this group will be visited by the researcher in their rooms on the morning before the surgery. Patients will be informed that they will be visited again in the evening of the day before the surgery and that they will be given a pillow to use while sleeping at night. They will receive no other interventions.Patients will be visited again on the morning of the surgery day.The Richard Campbell Sleep Scale was used to evaluate the nighttime sleep quality of the patients;General Comfort Scale to evaluate comfort levels.
  2. The Intervenion Group: The patients in this group will be visited by the researcher in their rooms on the morning before the surgery. Patients will be informed that they will be visited again in the evening of the day before the surgery and that they will be given a pillow to use while sleeping at night. Patients who are visited in their rooms on the evening of the day before the surgery will be given a gel pillow with a cooling surface feature for night use. If patients stop using pillows at night, they will be asked to inform the investigator when they come to their room in the morning.Patients will be visited again on the morning of the surgery day.The Richard Campbell Sleep Scale was used to evaluate the nighttime sleep quality of the patients;General Comfort Scale to evaluate comfort levels.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention Group
Patients who are visited in their rooms on the evening of the day before the surgery will be given a gel pillow with a cooling surface feature for night use. Patients will be asked to note the time they go to bed for a night's sleep and the time they wake up on the morning of the surgery. If patients stop using pillows at night, they will be asked to inform the investigator when they come to their room in the morning.Patients will be visited again on the morning of the surgery day.The Richard Campbell Sleep Scale was used to evaluate the nighttime sleep quality of the patients;General Comfort Scale to evaluate comfort.
Other: Using a gel pillow
Within the scope of the study, gel pillows with a cold surface were used in the patients in the study group. It is produced by combining the obtained special liquid with elastic material with NASA approved molecule exchange technology and is made of OEKO-TEX CLASS 1 certified material.Thanks to the gel material on the pillow surface, the surface temperature is reduced from 37°C to 24°C in about 10 seconds. It gives a feeling of coolness with its thermal conductivity feature.
No Intervention: Control Group
The patients who were visited in their rooms on the evening of the day before the operation will be given pillows that have the same characteristics as the pillows that the patients in the study group will use, but do not have a gel surface, to use at night. Patients will be asked to note the time they go to bed for a night's sleep and the time they wake up on the morning of the surgery.Participants in the control group will receive no other interventions.Patients will be visited again on the morning of the surgery day.The Richard Campbell Sleep Scale was used to evaluate the nighttime sleep quality of the patients;General Comfort Scale to evaluate comfort levels.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sleep quality level
Time Frame: 12 mounth
Sleep quality of the patietns will be evaluated with Richards Campbell Sleep Scale. Each item in the scale is evaluated on a chart between 0 and 100 using the visual analog scale technique. The total score of the scale is evaluated over 5 items, and the 6th item, which evaluates the noise level in the environment, is excluded from the total score evaluation. A score of "0-25" from the scale indicates very bad sleep, and a score of "76-100" indicates very good sleep. The high score of the scale indicates that the sleep quality of the patients is high.
12 mounth

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comfort level
Time Frame: 12 mounth
Comfort level of the patietns will be evalueated with General Comfort Scale. The lowest total score that can be obtained from the scale is 48, and the highest total score is 192. The average value is determined by dividing the total score obtained by the number of scale items, and the result is indicated in the 1-4 distribution. Low comfort is expressed by one point, high comfort by four points.
