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

To assess the diagnostic validity and cost-effectiveness of a APNiA device, a home respiratory polygraphy (HRP), performed at home compared with the standard polysomnography (PSG) in adults with clinically suspected Obstructive Sleep Apnea (OSA).

METHODOLOGY: DESIGN: Randomized, prospective, multicenter, and crossover trial. The study will include 240 adults, both sexes, with clinical suspicion of obstructive sleep apnea (OSA). MEASUREMENTS: To all patients with clinical suspected OSA and referred to the sleep units, the following questionnaires and measurements will be performed: a) clinical history; b) Anthropometric variables: weight, height, body mass index, neck circumference and percentile; c)Epworth sleepiness scale; OSA questionnaire, quality of life and clinical questionnaires and comorbidity; d) PSG in the sleep laboratory; e) HRP at home; f) Cost-effectiveness variables.

ANALYSIS: Data from HRP and from full PSG will be compared as follows: 1) Agreement of results according to the different apnea-hypopnea index by using the Receiver Operating Characteristic (ROC) curve; 2) The concordance of the diagnosis and treatment decisions when using clinical findings and data from PSG or HRP at home; 3) All data will be analyzed independently; 4) A cost-effectiveness analysis of the different diagnostic and therapeutic procedures will be performed.

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.

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
Apnea-Hypopnea Index (AHI)
Time Frame: baseline
To assess the diagnostic validity of a home respiratory polygraphy (HRP) compared with the standard polysomnography (PSG) in adults with clinically suspected Obstructive Sleep Apnea (OSA), based on the results of the Apnea-hypopnea Index (AHI).
baseline

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
Epworth Sleepiness Scale
Time Frame: baseline and at 6 month
The Epworth Sleepiness Scale (the sum of 8 items score,0-3) can range from 0 to 24. Scores of 11-24 represent increasing levels of excessive daytime sleepiness.

Blood pressure
Time Frame: baseline and at 6 month
Blood pressure measurements: systolic blood pressure and diastolic blood pressure
baseline and at 6 month
Anthropometric variables (Body mass index)
Time Frame: baseline and at 6 month
Body mass index
baseline and at 6 month
Quality of life (EuroQOL test)
Time Frame: baseline and at 6 month
Evaluate by EuroQOL test, is a standardised measure of health status. Description of the state of health in five dimensions (mobility, self-car, usual activities, pain/discomfort and anxiety/depression), each o wich is defined with three levels of severity, as measured by a Likert scale type (no problems, some problems and many problems or inability to activity).
baseline and at 6 month
Therapeutic decision
Time Frame: 6 month
The concordance of the diagnosis and treatment decision when using clinical findings and data from standard polysomnography (PSG) or home respiratory polygraphy (HRP).
6 month
STOP-BANG Sleep apnea questionnaire
Time Frame: baseline and at 6 month
Sleep Apnea Questionnaire. High STOP-Bang score indicates a high probability of obstructive sleep apnea.
baseline and at 6 month
Berlin questionnaire
Time Frame: baseline and at 6 month

The questionnaire consists of 3 categories related to the risk of having sleep apnea. Patients can be classified into High Risk or Low Risk based on their responses to the individual items and their overall scores in the symptom categories.

High Risk:

if there are 2 or more categories where the score is positive.

Low Risk:

if there is only 1 or no categories where the score is positive.
