The Improving Care in Chronic Obstructive Lung Disease Study A Cluster Randomized Trial (CAROL)

June 17, 2016 updated by: University of Zurich

The Improving Care in Chronic Obstructive Lung Disease Study: CAROL Improving Processes of Care and Quality of Life of COPD Patients in Primary Care: A Cluster Randomized Trial

Background The Swiss health ministry launched a national quality program "QualiCCare" in 2011 to improve healthcare for patients with COPD.

The aim of this study is to determine whether participation in the COPD quality initiative ("QualiCCare") improves adherence to recommended clinical processes and shows impact on patients COPD care and on quality of life in patients with COPD.

Study Overview

Status

Status

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

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.

Detailed Description

The care in obstructive lung disease study (CAROL) is a cluster-randomized controlled trial with randomization on the practice level. Thirty practices will be randomly assigned to equally sized intervention group or control group.

Each General Practioner (GP) of a practice will approach consecutively and regardless the reason for the current encounter, COPD patients diagnosed by spirometric evaluation (FEV1/ FVC < 0.70), aged 45 years older, with a smoking history of = 10 pack-years (PY). GPs in the intervention group will receive "QualiCCare" education, which addresses knowledge, decision-making and behavioural aspects as well as delivery of care according to COPD quality indicators and evidence based key elements. In the control group no educational intervention will be applied and COPD patients will be treated as usual. The study period is one year.

The primary outcome measure is an aggregated score of relevant clinical processes defining elements in the care of patients with COPD: smoking cessation counseling, influenza vaccination, motivation for physical activity, appropriate pharmacotherapy, patient education and collaborative care.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
216

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

45 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

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.
Active Comparator: QualiCCare education
"QualiCCare"education is a training workshop designed to educate professionals on the guidelines but also and particularly governing professional behavior by feedback, reminders and pathways that help to change their attitudes and care behavior. Based on behavioral and learning theory, QualiCCare intervention not only tries to increase knowledge but also internal motivation and decision making by stimuli and resources and by written instruments that guide evidence based decision support.
Behavioral: active comparator, QualiCCare education
Physicians randomized into the intervention group get a "QualiCCare" training workshop designed to educate professionals on the guidelines but also and particularly governing professional behavior by feedback, reminders and pathways that help to change their attitudes and care behavior. Based on behavioral and learning theory, QualiCCare intervention not only tries to increase knowledge but also internal motivation and decision making by stimuli and resources and by written instruments that guide evidence based decision support.
No Intervention: usual care
The practices randomized to the control group apply care as usual

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.
Outcome Measure
Measure Description
Time Frame
"Quality of care process"
Time Frame: one year
Difference in "quality of care process" (total increase in performed measures/fulfilled indicators) will be assessed after one year between COPD patients in the intervention and control group as reported by the patient
one year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quality of life
Time Frame: one year
We use the COPD Assessment Test (CAT). The CAT provides clinicians and patients with a reliable measure of overall COPD-related health status for the assessment and long-term follow-up of individual patients. The CAT is a validated short and simple patient-completed questionnaire that has been developed for use in routine clinical practice to measure the health status and grading the impact of COPD on patients' life. The CAT has very similar discriminative properties to the much more complex SGRQ (St. Georges Respiratory Questionnaire), and is available in different languages. It compromises 8 simple questions, 8 items on a scale 0-5 with a total scoring range of 0-40. CAT score <10 low impact, 10-20 medium impact >30 very high impact of COPD on patients life
