About this study

Official title: Evaluación de la Rentabilidad y Sensibilidad Del análisis automático Contra el análisis Manual de la poligrafía en el diagnóstico de Apnea Obstructiva Del sueño.

Obstructive sleep apnea (OSA) is a chronic pathology that affects more than 20% of the adult population. It is one of the main sleep disorders with great clinical, economic and social repercussions.

To assess the impact and severity of obstructive sleep apnea, the number of apneas and hypopneas per hour (AHI) is counted. To define that a person has OAS, a sleep study must have an AHI ≥15/h, predominantly obstructive, or the presence of an AHI ≥5/h accompanied by symptoms.

The diagnosis of certainty or exclusion, as well as the severity, is established with a sleep study. Polysomnography (PSG) continues to be the gold standard for the diagnosis of OSA, it encompasses the recording of cardiorespiratory and neurophysiological variables, which makes it possible to analyze sleep time and structure, the presence of different respiratory episodes and their repercussions. Respiratory polygraphy (RP) includes recording from a flow sensor, respiratory effort, oxygen saturation, heart rate, and also position but not EEG. There are several studies that have explored the diagnostic agreement of RP versus PSG, being a validated, useful and necessary test for the diagnosis of OSA in different clinical situations. Being cheaper and more accessible.

When talking about the diagnosis of OSA, it refers to establishing whether or not there is, the severity and the therapeutic decision that will greatly affect the quality of life, prognosis and day-to-day life of the patient, since it is a chronic disease.

It must be borne in mind that most studies are carried out in a field specialized in dream interpretation, so caution must be exercised in interpreting results in another field. PR teams incorporate increasingly better developed software that allows automatic analysis of records, but the technology and algorithms used vary depending on the device, and up to now the AASM continues to recommend manual analysis based on existing evidence. Several studies have examined the agreement between automatic and manual analysis of the PR record or between automatic analysis of PR and PSG. It seems that this agreement is reached above all in the highest AHIs, above 25-30, which may limit its use in clinical practice.

For this reason, it is important to carry out a study with a large number of patients to achieve statistical significance, and strong conclusions that support normal clinical practice, and to disable a study that does not meet the scientific requirements when interpreting and reading.

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea, run by Hospital San Pedro de Logroño at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of the Cost-Effectiveness and Sensitivity of Automatic Analysis Versus Manual Analysis of Polygraphy in the Diagnosis of Obstructive Sleep Apnea. (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jun 2024.
