What is being measured

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

  1. 6 minute walking test distance

    To measure distance subject could walk during the period of 6 minute

    Measured: 2 months

Secondary outcomes (8)
  1. Quality of life by questionaires: COPD Assessment Test (CAT)

    Using COPD Assessment Test (CAT) questionaires to assessing globally the impact of COPD (cough, sputum, dyspnea, chest tightness, activities, confident, sleep and sleep) on health status

    • Range of CAT scores from 0-40. Higher scores denote a more severe impact of COPD on a patient's life

    Measured: 2 months

  2. Quality of life by questionaires: modified British Medical Research Council Dyspnea Scale (mMRC)

    Using COPD modified British Medical Research Council Dyspnea Scale (mMRC) to assess the degree of functional disability due to dyspnea.

    Measured: 2 months

  3. Quality of life by questionaires: St. George's Respiratory Questionnaire (SGRQ)

    Using St. George's Respiratory Questionnaire (SGRQ) to measure impact on overall health, daily life, and perceived well-being in patients with obstructive airways disease.

    SGRQ is divided into 2 part

    • Part I (Symptoms): several scales.
    • Part II (Activity and Impacts): dichotomous (true/false). Scores range from 0 to 100, with higher scores indicating more limitations.

    Measured: 2 months

  4. Quality of life by Sleep quality questionaires: Pittsburgh Sleep Quality Index (PSQI)

    Using Pittsburgh Sleep Quality Index (PSQI) to assesses adult patients' sleep quality and disturbances over one month with question about Subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.

    Measured: 2 months

  5. Quality of life by Sleep quality questionaires: Functional Outcomes of Sleep Questionnaire (FOSQ)

    Using Functional Outcomes of Sleep Questionnaire (FOSQ) to to determine functional status in adults; measures are designed to assess the impact of disorders of excessive sleepiness on multiple activities of everyday living and the extent to which these abilities are improved by effective treatment.

    The questionaire ask about activity level, vigilance, intimacy and sexual relationships, general productivity, social outcome, rate the difficulty of performing a given activity on a 4-point scale (no difficulty to extreme difficulty)

    Measured: 2 months

  6. Quality of life by Sleep quality questionaires: Epworth Sleepiness Scale (ESS)

    Using Epworth Sleepiness Scale (ESS) to measure sleepiness in daily life. The ESS asks the patient to rate their likelihood of falling asleep under 8 different circumstances.

    Measured: 2 months

  7. Quality of life by Sleep quality questionaires: Lausanne NoSAS (Neck circumference, Obesity, Snoring, Age, Sex) score

    Using Lausanne NoSAS (Neck circumference, Obesity, Snoring, Age, Sex) score to guide identification of individuals at risk of sleep-disordered breathing

    Measured: 2 months

  8. Aerobic capacity

    Measure oxygen consumption during performing 6 minute walking test

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing CPAP therapy in people with COPD and OSA, run by Mahidol University at 1 site in Thailand.

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 4 inclusion and 10 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 5 Feb 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 Thailand. 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?

6 minute walking test distance (time frame: 2 months). 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 5 Feb 2024.
