Study population: Patients with diagnosis of OSA. According to the International Classification of Sleep Disorders, OSA was defined as the presence of 5 or more obstructive respiratory events (apnea, hypopnea or respiratory effort-related arousal) per hour of sleep plus daytime or nighttime symptoms of OSA, alternatively as the presence of 15 or more obstructive respiratory events per hour of sleep

Who may be able to join

  • diagnosis of OSA
  • admitted for adaptation to CPAP

Who cannot join

  • other sleep related diseases
  • concomitant lung or thoracic diseases (including chronic respiratory failure requiring long term oxygen therapy)
  • major comorbidities (e.g. psychiatric conditions, cancer, end-stage renal failure)
  • familiar conditions preventing long-term home CPAP
  • patients already treated with CPAP

About this study

Official title: Adherence to Continuous Positive Airway Pressure in Patients With Obstructive Sleep Apnoea Syndrome. Ten Year Follow up

The management of OSA is aimed to improve symptoms and mitigate reduce other health consequences. Continuous Positive Airway Pressure (CPAP) is the recognized treatment for OSA, able to reverse the pathophysiology of OSA and improving sleep continuity, resulting in improvements in daytime sleepiness and quality of life (QoL). However, low adherence to this treatment reduces the potential to achieve these benefits. The aim of this real life retrospective observational study was to assess the adherence to CPAP at 12 month and 10 years. The investigators evaluated also predicitve factors of adherence.

Read the detailed description

Methods The protocol was approved (2215 CE, June, 19, 2018) by the Ethical Committee of the Istituti Clinici Scientifici (ICS) Maugeri, Pavia, Italy. All patients at admission to the Scientific Institute of Tradate gave the informed consent to the scientific use of their data.

Study Participants This study was conducted on a database of patients' discharge records, available between August, 2006 and December, 2009.

Adaptation to CPAP: titration of CPAP was performed either by full-night manual titration according to the AASM Guidelines or by automatic titration with Auto-Set systems. Further 4 day-time hours of adaptation were performed along two days. Patients underwent also four face to face sessions with the respiratory therapist, for feed-back of adaptation, optimal comprehension of procedure of CPAP management. The presence of a caregiver (if any) was strongly suggested.

Statistical Analysis An ad hoc electronic form was created to collect all study variables. Qualitative variables were described with absolute and relative (percentages) frequencies, whereas quantitative variables were summarized with means (standard deviations) or medians (interquartile ranges) based on their normal distribution, respectively.

In-between comparison for qualitative and quantitative variables was performed with the chi-squared or Fisher exact test when appropriate, and Student t or Mann-Whitney test in case of parametric or non-parametric distribution, respectively. Comparison of the temporal variation of continuous variables for the same group was assessed with Anova or Friedman's test, depending on their normal distribution.

Uni- and multi-variable logistic regression analysis was performed to assess which covariates could be associated with the adherence to CPAP.

A two-tailed p-value <0.05 was considered significant. All statistical analyses were carried out using the statistical software STATA version 15 (StatsCorp, Texas).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CPAP use

    number of Night-time hours of use (device counter)

    Measured: Every 12 month for 10 years.Scale from 0 to 8 hours/night. Values >4,5 hours/night are considered to be a better outcome

Secondary outcomes (2)
  1. Body weight

    Kg

    Measured: once a year for 10 years

  2. Reported patients' day-time sleepiness

    Epworth Sleepness Scale (ESS).The questionnaire asks the subject to rate his/her probability of falling asleep on a scale of increasing probability from 0 to 3 for eight different situations that most people engage in during their daily lives. The scores for the eight questions are added together to obtain a single number. A number in the 0-9 range is considered to be normal while a number in the 10-24 range indicates that expert medical advice should be sought

    Measured: once a year for 10 years

Questions about this trial

What is this clinical trial studying?

An observational study of OSA and Adherence, Patient, run by Maugeri Foundation at 1 site in Italy.

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 5 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 23 Aug 2018. 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 Italy. 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?

CPAP use (time frame: Every 12 month for 10 years.Scale from 0 to 8 hours/night. Values >4,5 hours/night are considered to be a better outcome). 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 23 Aug 2018.
