The modified Medical Research Council dyspnoea scale is a good indicator of health-related quality of life in patients with chronic obstructive pulmonary disease

Abstract

RESULTSSignificant differences were found in many more domains of the two questionnaires between mMRC grades than between GOLD stages. In the multiple linear regression model, the mMRC scale was the only factor that remained determinative of all the domains of SGRQ and WHOQOL-BREF. Patients with chronic productive cough, sleep disorders and frequent exacerbations had poorer HRQoL, as reflected by higher scores in SGRQ or lower scores in WHOQOL-BREF. CONCLUSIONThe mMRC dyspnoea scale is a concise and practical tool to assess the HRQoL of patients with COPD in daily clinical practice.

Associations of cognition with physical functioning and health-related quality of life among COPD patients

“…We included several covariates to adjust for disease severity, comorbidity, psychological functioning, and demographic characteristics. COPD severity measures included forced expiratory volume in 1 s percent predicted (FEV 1 %), the modified Medical Research Council (mMRC) dyspnea scale [28], COPD hospitalization in the last year (yes/no) and use of supplemental oxygen (yes/no). We also calculated a BODE index (Body mass index, airflow Obstruction, Dyspnea and Exercise capacity) [29], a composite multidimensional COPD severity measure that includes FEV 1 %, 6MWT, mMRC dyspnea scale, and body mass index (BMI) [28].…”

“…COPD severity measures included forced expiratory volume in 1 s percent predicted (FEV 1 %), the modified Medical Research Council (mMRC) dyspnea scale [28], COPD hospitalization in the last year (yes/no) and use of supplemental oxygen (yes/no). We also calculated a BODE index (Body mass index, airflow Obstruction, Dyspnea and Exercise capacity) [29], a composite multidimensional COPD severity measure that includes FEV 1 %, 6MWT, mMRC dyspnea scale, and body mass index (BMI) [28]. Comorbidity was assessed with BMI and the Charlson Comorbidity Index (CCI) [30], a commonly used weighted composite measure of common chronic conditions.…”

Correlation of chest computed tomography findings with dyspnea and lung functions in post-tubercular sequelae

“…[21] The mMRC scale is a good index of the quality of life in patients with chronic obstructive pulmonary disease (COPD) and other respiratory disorders and correlates well with functional impairment. [2122] Smoking history was noted, and patients categorized as current smokers, previous smokers (those having quit 6 months prior or earlier), and nonsmokers.…”

Administration of vitamin D to ameliorate dyspnea of chronic obstructive pulmonary disease patients: a randomized controlled trial

“…The study was performed on patients who admitted as COPD cases (based on history and pulmonary function tests) in the Vali-e-Asr university hospital of the Zanjan (2016). According to global obstructive lung disease (GOLD) criteria, patients were categorized in stages of II, III and IV (11). Forty COPD patients with vitamin D deficiency were enrolled into two groups; cases group who used vitamin D and control group who received placebo.…”

“…Finally, the findings of spirometry, serum vitamin D level and degree of dyspnea based on the modified Medical Research Council (mMRC) dyspnea scale were recorded in both groups (10). Age, gender, height, weight, occupation, duration of disease, smoking per pack/year and possible history of corticosteroid consumption of patients was collected using questionnaire (11). Inclusion criteria were; COPD patients without exacerbations during the past two weeks.…”
