About this study

Official title: Population Medicine Multimorbidity Interventions in Xishui on a High-Risk COPD Population: A Cluster Randomized Controlled Trial

Study Participants: High-risk COPD population, defined as individuals whose score of COPD-SQ is 16 and above and whose age is 35 and above. COPD-SQ questionnaire will be assigned to a representative sample of local residents in Xishui County, and they will finish the questionnaire online through mobile phone.

Intervention: Within the intervention arm, we have constructed a population-based pay-for-performance mechanism to encourage medical practitioners to care for population health. For study participants in the intervention arm, we will ask them to finish an online COPD-SQ questionnaire with notification of his or her COPD high risk status. Those whose score exceeds 16 will be invited to do a face-to-face survey, simple physical examination, pulmonary function tests, and provide a multi-component intervention at baseline. For High-risk COPD population in the intervention arm, we provide community-based spirometry pulmonary function test (PFT) and education; If individuals whose post-bronchodilator FEV1/FVC<0.7, they will be spirometry-defined COPD patients and will be encouraged to seek treatment and medication to the superior hospitals. Additionally, we provide (1) two digital health intervention programs to smokers and individuals with mental health issues; (2) CBT-based health education for study participants with abnormal BMI; (3) active recruitment into National Essential Public Health Program in China for those with abnormal blood pressure and blood glucose. Intensive follow-ups will be conducted at month 3 (telephone interview), month 6 (face-to-face with full steps of physical examination), and month 12.

Comparison: Those who are assigned in the control arm, we will ask them to finish the same COPD-SQ online questionnaire with notification of his or her COPD high risk status and a face-to-face survey. No physical examinations, community-based pulmonary function tests will be given.

Outcomes: The primary outcomes are COPD knowledge, COPD screening, and FEV1 measurement at month 12.

  40. Productivity loss

    Working Productivity and Activity Impairment-General Health (WAPI-GH) Chinese version 2.0 is used. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes, as follows:

    Questions:

    1. = currently employed
    2. = hours missed due to health problems
    3. = hours missed other reasons
    4. = hours actually worked
    5. = degree health affected productivity while working
    6. = degree health affected regular activities

    Scores:

    Multiply scores by 100 to express in percentages.

    Percent work time missed due to health: Q2/(Q2+Q4)

    Percent impairment while working due to health: Q5/10

    Percent overall work impairment due to health:

    Q2/(Q2+Q4)+[(1-(Q2/(Q2+Q4)))x(Q5/10)]

    Percent activity impairment due to health: Q6/10

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Multi-component intervention package in people with Multimorbidity and Population Medicine, run by Peking Union Medical College at 1 site in China.

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

The record lists 1 site in China. 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?

Number of Chronic Diseases Controlled (time frame: 1 year). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06456996, which also lists 1 linked publication.

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?
