Follow-up of Patients With Obstructive Sleep Apnea in Primary Care.

November 24, 2014 updated by: Ferran Barbe, Sociedad Española de Neumología y Cirugía Torácica

Follow-up of Patients With the Apnea-hypopnea Syndrome in Primary Care and Sleep Disorders Units. Equivalence Randomized Comparative Study on Compliance and Clinical Response.

The objective of the study is to compare the results of a coordinated and interactive program for the treatment, monitoring and control of patients with a moderate-severe diagnosis of Obstructive Sleep Apnea (OSA) and treated with positive continuous pressure (CPAP), with the currently established situation.

Methodology: Equivalence randomized comparative study . It will include patients with diagnosis of moderate-severe OSA (apnea-hypopnea Index >=15) that should start treatment with (CPAP). Participating center is Hospital Santa María-Arnau de Vilanova in Lleida (Spain).These patients will be randomized to two monitoring groups (1: monitoring in the Sleep disorders unit, 2: monitoring in primary care consultations) once the OSAS diagnosis has been made and it was indicated that treatment with CPAP. Patients Will be carried out in both groups the same follow-up visits in two study arms: basal, 1 month, 3 months and 6 months. Primary outcomes: number of hours of use per day (according to the accountant of the CPAP), so that use >= 4h/day is defined as good adherence to the treatment. Secondary outcomes: daytime sleepiness, patient satisfaction, Adverse events related to CPAP treatment. It will be collected demographic ,clinics and anthropometric variables. At the end of follow-up primary and secondary outcomes will be compared between two groups.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Men and women over 18 years old.
  • Patients with OSA diagnosis performed in the sleep units
  • Written informed consent signed.

Exclusion Criteria:

  • Previous CPAP treatment for OSA diagnosis
  • Psycho-physical inability to complete questionnaires.
  • Presence of any previously diagnosed sleep disorders: narcolepsy, insomnia, chronic sleep deprivation, regular use of hypnotic or sedative medications and restless leg syndrome
  • Patients with respiratory diseases (overlap syndrome, hypoventilation, restrictive diseases)
  • A medical history that may interfere with the study objectives or, in the opinion of the investigator, compromise the conclusions.
  • Any medical factor, social or geographical, that may jeopardize patient compliance.(e.g., alcohol consumption (more 80 gr/day in men and more than 60 gr / day in women), no fixed address, disorientation, or a history of non-compliance).

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: Sleep Unit group
This group will have standard follow up in sleep unit at 1, 3 and 6 month. These patients will also be instructed in hygienic-dietary measures, standard care of cardiovascular risk factors and sleep hygiene counseling.
Experimental: Primary Care group
This group will have standard follow up in primary care at 1, 3 and 6 month. These patients will also be instructed in hygienic-dietary measures, standard care of cardiovascular risk factors and sleep hygiene counseling.
Other: Clinical follow up by general practitioners in primary care
The study evaluates two different setting to follow up patients with obstructive sleep apnea on CPAP treatment

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.
