Izmir Katip Celebi University340 enrolled

Overview

The Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD) Patient and Resident Proxies questionnaire, which can be used in patients with Chronic Obstructive Pulmonary Disease (COPD) and their relatives, will be adapted into Turkish and its psychometric properties will be examined, and the knowledge level of patients and their relatives about the disease and general health will be investigated.

The socio-demographic characteristics of the patients and their relatives will be obtained by asking to them by mutual interview method. A disease-specific test, the COPD Assessment Test (CAT), will be used to assess patients' own health, and the St George Respiratory Questionnaire (SGRQ) will be used to assess patients' quality of life. Comorbidities reported by the patient and their relatives will be filled in the Charlson Comorbidity Index. The dyspnea that patients encounter in their daily lives will be questioned with the Modified Medical Research Council (mMRC) Dyspnea Scale. The "Individual Knowledge Statements of Patients and Resident Proxies" will be used for the individual information of the patient and their relatives about the disease and general health. There is no control group in the study. SGRQ, CAT and numerical rating scale will be used for the validity of the Turkish version of Individual Knowledge Statements of Patients and Resident Proxies. For the test-retest, the evaluation will be done again after 15 days.

Interventions

QuestionnaireOTHER

Patients will do the Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD), the COPD Assesment Test (CAT), the Saint George Respiratory Disease Questionnaire (SGRQ), the Charlson Comorbidity Index, and will rate the disease and general knowledge level on a numerical scale. Proxies of patients will do the Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD) and will rate the disease and general knowledge level on a numerical scale.

Outcomes

Primary Outcomes

Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD)

The scale is a 34-item questionnaire that evaluates the knowledge of COPD patients and their relatives about the disease and general health. All of 34 statements can be answered as "true", "false" or "don't know". A score out of 34 points will be obtained by giving 1 point to each correct answer appropriate to the question. Higher score will show more knowledge level. It will done by patients and their proxies.

Time frame: Baseline

Secondary Outcomes

COPD Assesment Test (CAT)

The COPD Assessment Test (CAT) is a questionnaire, which consist of 8 questions, for people with COPD. It is designed to measure the impact of COPD on a person's life, and how this changes over time. The eight questions are each rated on a scale of 0 to 5. Range of CAT scores from 0-40. Higher scores denote a more severe impact of COPD on a patient's life. It will done by patients.

Time frame: Baseline

The modified Medical Research Council (mMRC) scale

The mMRC scale is a self-rating tool to measure the degree of disability that breathlessness poses on day-to-day activities on a scale from 0 to 4: 0, no breathlessness except on strenuous exercise; 1, shortness of breath when hurrying on the level or walking up a slight hill; 2, walks slower than people of same age on the level because of breathlessness or has to stop to catch breath when walking at their own pace on the level; 3, stops for breath after walking ∼100 m or after few minutes on the level; and 4, too breathless to leave the house, or breathless when dressing or undressing. It will done by patients.

Time frame: Baseline

Charlson Comorbidity Index

The Charlson Comorbidity Index is a method of categorizing comorbidities of patients based on the International Classification of Diseases (ICD) diagnosis codes found in administrative data, such as hospital abstracts data. Each comorbidity category has an associated weight (from 1 to 6), based on the adjusted risk of mortality or resource use, and the sum of all the weights results in a single comorbidity score for a patient. A score of zero indicates that no comorbidities were found. The higher the score, the more likely the predicted outcome will result in mortality or higher resource use.
