Twenty-eight patients with chronic lung disease received initial and follow-up questionnaires 2 weeks later after treatment had been initiated. Measuring patient and clinical perspectives to evaluate change in health-related quality of life among patients with chronic obstructive pulmonary disease.

A comparison of three disease-specific and two generic health-status measures to evaluate the outcome of pulmonary rehabilitation in COPD. Combining scores from different patient reported outcome measures in meta-analyses: Patient —assessed health outcomes in chronic respiratorg disease: The CRQ are validated and reliable quality of life measures for patients with chronic airflow limitations. The researchers qusstionnaire that on average, scores on the CRQ needed to change by about 0.

The CRQ scores also follow predicted tracts and correlate well with clinical status. Foundations of Clinical Research: There is currently no gold standard for determining HRQL, 20 so the validity of the CRQ has been assessed primarily through construct and convergent validity. Chroinc et al 26 used standardized response means to assess the sensitivity and also found the CRQ-SR to be highly sensitive across all domains of the questionnaire indicating that it is able to detect changes following a treatment program.

Comparison of discriminative properties among disease-specific questionnaires for measuring health-related quality of life in patients with chronic obstructive pulmonary disease. Subsequent versions of the test have been developed to improve time and ease of administration. Lower correlation scores were noted in the second 6 month period; however, they were not significant enough to indicate resporatory bias existed between assessments.

This may also increase the chances of the patient answering more honestly. High response rates to this type of questionnaire have been achieved in outpatient settings; however, the interview form is quite expensive 13 and time consuming. Georges Respiratory Questionnaire and four other health-related quality of life instruments for patients with chronic lung disease.

This may uqestionnaire a factor to consider when administering the CRQ. Suestionnaire information Copyright and License information Disclaimer. In the first assessment, the tool was administered to 13 patients all diagnosed with chronic lung disease and the patients were then reassessed 2 to 6 weeks later after treatment had been initiated.

Outcomes in Cardiopulmonary Physical Therapy: Chronic Respiratory Disease Questionnaire (CRQ)

Important considerations for questionnaires such as CRQ include the ease and cost of administration. The original version of the CRQ was developed in by Guyatt et al 2 and followed Kirshner and Guyatt’s 7 principles of questionnaire development.

It is not strongly correlated with physiologic measures related to dyspnea, indicating the need to respiratroy HRQL tools alongside physiologic measures in order to gain the full picture of the patient’s disease state.

Assessing the minimal important differences in symptoms: The total domain and the emotion domain scores were determined to be the most responsive to these changes. For this reason, it is important to evaluate the outcomes of various interventions to ensure that patients are receiving the most efficient and best available care.

According to the office of the developer, written communication, October, using the CRQ-IAS, in which the dyspnea section is also standardized, reduces the administration time to 8 minutes.

Pearson correlation coefficients were used to determine consistency over time of both individual item scores and domain total scores. List per page or resoiratory all.

Also, in this specific patient population, improvements in breathlessness or exercise tolerance may not be noticed since these patients are accustomed to avoiding activities that stimulate these symptoms. A mean change per question of 0. A novel, short, and simple questionnaire to measure health-related quality of life in patients with chronic obstructive pulmonary disease.

Test-retest reliability of the CRQ has been found to be high. Validity and reliability of a quality-of-life instrument: Wijkstra 10 determined that significant correlations exist between the CRQ fatigue domain and the depression and somatisation domain of the Symptom Checklist 90 SCL They also tespiratory that the baseline scores for the self-reported test were significantly lower across all domains than for the interviewer-administered questionnaire.


It is recommended that both general and condition specific HRQL questionnaires be administered alongside physiologic tests since each of these contribute unique information regarding disease state and quality of life. Measurement of health status: This indicates that the CRQ was able to detect the change in patient condition that occurred with treatment.

Measuring health related quality of life.

The CRQ is available in four different formats approximate time needed for the first administration: When all 4 of the domains were included, the MCID was 0. It correlates well with other disease specific and generic measures of HRQL as well as with global ratings of change. Power of outcome measurements to detect clinically significant changes in pulmonary rehabilitation of patients with COPD.

Chronic Respiratory Disease Questionnaire (CRQ)

Establishing the minimal number of items for a responsive, valid, healthrelated quality of life instrument. In comparison with global ratings of change, the CRQ was found to have moderate to high correlations 2 which were significantly stronger than those of generic health measures. Because under some circumstances investigators will want to use identical questions for ALL respondents the CRQ has been standardized through inclusion of five identical questions inquiring about dyspnea.

Comparison of outcome measures rsepiratory patients with chronic obstructive pulmonary disease COPD in an outpatient setting. Reliability, or reproducibility, can be determined in 3 ways: HRQL is commonly assessed through self or interviewer administered questionnaires, and may be discriminative evaluating cross-sectional differences between patients at a single point in time or evaluative measuring longitudinal changes within patients over a period of time.
