Poor perceptions and expectations of asthma control: results of the International Control of Asthma Symptoms (ICAS) survey of patients and general practitioners.

AIMS: To assess current levels of asthma control and to identify barriers to optimal asthma management. METHODS: A survey was conducted of 802 asthma patients (via computer-aided telephone interviewing) and 809 general practitioners (GPs; via the internet) from the UK, Italy, France, Germany, Spain, Canada and Australia. RESULTS: Over three-quarters (82%) of patients surveyed reported an absence of asthma control, with the vast majority (80%) experiencing subsequent lifestyle restrictions. Although most (58%) GPs questioned believed that total asthma control was possible, half (52%) agreed that their patients were not achieving best possible asthma control. CONCLUSIONS: Action is required to encourage patients to view their asthma more seriously and to be more proactive in reporting symptoms to their GP. These actions, coupled with greater prompting of patients by GPs about their asthma, should help to optimize asthma management.     

Increased occurrence of respiratory symptoms is associated with indoor climate risk indicators - a cross-sectional study in a Swedish population

BACKGROUND: A basic assumption was that exposure to the indoor environment would increase the manifestation of respiratory symptoms in predisposed individuals. The aim was to investigate the proportion of perceived respiratory symptoms attributed to specific environmental exposures, and associations related to indoor climate risk indicators, i.e. occurrence of damp or mould, insufficient ventilation and condensation on windows. METHOD: A questionnaire was mailed to a random sample of 8008 individuals, stratified for gender and age. The response rate was 84% (n=6732). Established criteria for current asthma were used to classify subjects into three subgroups: asthmatics, healthy and symptomatics (but without current asthma). RESULTS: The proportion of symptoms attributed to specific environmental exposures increased in the total sample and in the three subgroups when indoor climate risk indicators, particularly damp or mould, were reported. Generally, the lowest proportions were found for healthy and the highest for asthmatics. Univariate analyses presented as relative risks (RR) (95% CI) showed significantly increased risks for perceived overall influence on airways for all groups, with RR ranging from 4.3 to 6.8. Although respiratory symptoms attributed to dust, environmental tobacco smoke (ETS) and strong scents increased when risk indicators were reported, RR were generally lower in all groups. CONCLUSION: The high frequency of respiratory symptoms among asthmatics increased when occurrences of risk indicators were reported. Similarly, increased symptoms were found for healthy indicating that indoor climate risk indicators may affect both healthy and unhealthy individuals.     

Patient satisfaction with healthcare in asthmatics and patients with COPD before and after patient education

Patient satisfaction with general practitioners (GP) and pulmonary outpatient clinics has not been previously compared in patients with asthma and chronic obstructive pulmonary disease (COPD) in addition to the effect of patient education on this satisfaction. We randomly allocated 78 asthmatics and 62 patients with COPD after ordinary outpatient management to a control or an intervention group. Intervention consisted of educational group sessions and individual sessions administered by a trained nurse and physiotherapist. A self-management plan was developed. A patient satisfaction questionnaire was answered at baseline and at the 1-year follow-up. Before randomization, a higher proportion of asthmatics were satisfied with the overall handling of their disease by the outpatient clinic (86%) compared with their GPs (72%, P=0.027, chi2-test). Equal and high proportions of patients with COPD were satisfied with both their GPs (85%) and the outpatient clinic (87%) and in general seemed more satisfied with their GP than asthmatics (P=0.064). At the 1 year follow-up, 100% of the educated patients with COPD reported overall satisfaction with GPs compared with 78% in the control group (P=0.023), but not for asthmatics (75 and 78%, respectively, P=0.581). We conclude that before being given education, asthmatics are more satisfied with the pulmonary outpatient clinic than with GPs, regarding the overall handling of their disease. Patients with COPD seemed more satisfied with GPs than asthmatics. For patients with COPD, patient education seemed to improve overall patient satisfaction with GPs, but this was not true for asthmatics. At baseline, overall satisfaction with the outpatient clinic was so beneficial that we had little chance of detecting any improvement.     

Assessment of asthma severity and treatment by GPs in Belgium: an Asthma Drug Utilization Research Study (ADUR)

A prospective study was performed between June 1996 and December 1997, to identify how general practitioners (GPs) in Belgium assess asthma severity and how they treat asthma according to their severity assessment. Three hundred and sixty-five GPs included 1376 already diagnosed and treated asthmatics.The GPs used a questionnaire providing data on patient demographics, aetiology of asthma, symptoms and medication use. The patients provided a complete diary card of day and night symptoms and morning and evening peak expiratory flow rates during a 3-week period. Asthma severity as assessed by GPs was compared with the severity according to the GINA guidelines. Along the same line, asthma treatment was evaluated according to the GPs assessment of severity and according to the GINA guidelines. Confronting the assessment of asthma severity by the GPs with the GINA criteria revealed that about 20% and 2% of the patients' asthma severity respectively were under- and over-estimated, respectively (using a discrepancy between GPs and GINA assessment of severity by 2 or more classes). Using the GINA criteria for treatment, only 37.5% of the patients seemed to be correctly treated. Taking a discrepancy between GINA assessment and treatment of two classes as an error, 2.3% and 23.4% of the asthmatics are over- and under-treated, respectively. In conclusion, this study provides evidence that GINA guidelines seem not to be adequately interpreted and implemented by GPs in Belgium. Improvement of the assessment of asthma severity is definitely needed and may lead to more appropriate use of asthma medication.     

Perceptions, impact and management of asthma in South Africa: a patient questionnaire study

INTRODUCTION: A number of studies from around the world have indicated that asthma morbidity is still unacceptably high. In the AIRE study over one-third of children and half of the adults reported daytime symptoms at least once a week. This study was conducted to understand the impact (including the impact on health-related quality of life) of asthma on South African asthmatics. MATERIALS AND METHODS: General Practitioners (GPs) and pharmacists in South Africa were randomly identified from the Medical Association database. These individuals were approached and asked to recruit asthmatic patients to complete a questionnaire. The questionnaire inquired about symptoms, quality of life, complications, trigger factors, associated allergic conditions, medication used, medication preference, medication adherence and concerns about the condition. RESULTS: 3347 respondents returned their demographic data but only 710 met the criteria for analysis, ie. had asthma and were presently on controller medication. Symptom analysis revealed that 21.4% of respondents were coughing on most days, 25.6% were wheezing on most days, and 22.8% were experiencing night-time symptoms on most days. Symptoms were exacerbated by exercise in 56.9%, while nocturnal wakening due to asthma occurred in 36.9% more than four times per week. Only 35.1% of respondents had not missed school or work in the preceding year. 45.4% of individuals worry about side effects of asthma therapy. CONCLUSION: This study indicates that there is under-treatment, inappropriate treatment and/or lack of patient education for asthma patients in South Africa. The data support the notion that poor therapy and/or poor patient adherence has an enormous impact on the health-related quality of life of South Africa's asthmatics.     

Asthma insights and reality in Turkey (AIRET) study

BACKGROUND: Several international surveys have reported low levels of asthma control compared to the levels set by the Global Initiative for Asthma guidelines. METHODS: In Turkey, 8350 households were surveyed and 400 current asthmatics responded a structured questionnaire on symptom severity, activity limitations and disease management. RESULTS: Most of the 55 children and 345 adults were classified as having persistent asthma (72.7% and 88.1%, respectively). In adult asthmatics, 31.3% reported current cigarette smoking and 10.7% being former smokers. Guideline-based asthma control was achieved in only 1.3% of participants. Three-quarters of children and more than 90% of adults were experiencing daytime symptoms. Most of adult patients and children reported an unfavorable impact of asthma on their social lives, and only half had ever had a lung function test. Daily anti-inflammatory therapy, including inhaled corticosteroids, was low in patients with persistent disease. Patients underestimated their disease severity and overestimated their level of disease control. CONCLUSIONS: The low level of asthma control in this Turkish population, together with the underestimation of disease severity and control by the patients, high smoking rates and low level of preventive medicine usage indicate a need for better implementation of current guidelines and patient education on asthma in Turkey.     

Acute asthma among pregnant women presenting to the emergency department.

Asthma complicates up to 4% of pregnancies. Our objective was to compare emergency department (ED) visits for acute asthma among pregnant versus nonpregnant women. We performed a prospective cohort study, as part of the Multicenter Asthma Research Collaboration. ED patients who presented with acute asthma underwent a structured interview in the ED, and another by telephone 2 wk later. The study was performed at 36 EDs in 18 states. A total of 51 pregnant women and 500 nonpregnant women, age 18 to 39, were available for analysis. Pregnant women did not differ from nonpregnant women by duration of asthma symptoms (median: 0.75 versus 0.75 d, p = 0.57) or initial peak expiratory flow rate (PEFR) (51% versus 53% of predicted, p = 0.52). Despite this similarity, only 44% of pregnant women were treated with corticosteroids in the ED compared with 66% of nonpregnant women (p = 0.002). Pregnant women were equally likely to be admitted (24% versus 21%, p = 0.61) but less likely to be prescribed corticosteroids if sent home (38% versus 64%, p = 0.002). At 2-wk follow-up, pregnant women were 2.9 times more likely to report an ongoing exacerbation (95% CI, 1.2 to 6.8). Among women presenting to the ED with acute asthma, pregnant asthmatics are less likely to receive appropriate treatment with corticosteroids.     

Asthma management and outcomes in Australia: a nation-wide telephone interview survey

Background and objective: Asthma is a high‐burden disease for which effective treatment is available. In Australia, there has been a public health campaign directed at increasing the implementation of effective management with the aim of improving asthma outcomes. The aim of this study was to assess the burden of asthma and describe current asthma management in Australia. Methods: A computer‐assisted telephone interview survey was conducted in 2003/04 among randomly selected participants. Current asthma was defined as self‐reported asthma, confirmed by doctor, which was still present and/or associated with symptoms in the last 12 months. Results: From 46 855 eligible telephone numbers dialled there were 14 271 (30.5%) responses to the screening questionnaire. Among 1734 respondents with current asthma, 1205 (69.5%) completed the detailed questionnaire. Among these, 24.2% of adults and 14.3% children had symptoms during the day or night on most days; 11.3% of adults and 6.0% of children avoided exercise because of asthma symptoms during exercise and 19.4% of adults and 29.7% of children had sought urgent medical care because of an exacerbation of asthma during the preceding year. Among adults with asthma, only 35.6% with daily symptoms and 41.4% with symptoms on most days were taking inhaled steroids. Only 31.1% of adults with daily symptoms had a written asthma action plan. Conclusion: Compared with similar international studies, this study revealed a lower prevalence of frequent asthma symptoms and a higher prevalence of use of inhaled steroids among people with asthma. However, there remains ample scope for improvement in management of patients with frequent symptoms.     

Comparison of clinical management of young and elderly asthmatics by respiratory specialists and general practitioners

Background: Asthmatic death in the elderly is a serious problem worldwide. Differences in clinical skill between respiratory specialists (RS) and general practitioners (GP) are important in asthma control. The aim of this study was to compare asthma management between RS and GP. Methods: A cross-sectional survey was carried out in Shimane, Japan, in February 2009 using a questionnaire about patient background, treatment, asthma control test (ACT) and adherence to treatment. We secured the cooperation of 48 clinics (39 private clinics and 9 general hospitals). Asthmatics were divided into the elderly and young groups, and also into the RS and GP groups. Results: Clinical data of 779 patients were available for analysis. Elderly patients constituted 464 (RS group: 192, GP group: 272), while those of the young group were 315 (RS group: 207, GP group: 108). RS prescribed inhaled corticosteroids (ICSs) to their elderly and young patients more than GP. The total ACT score was higher in young RS group than in young GP group, but no such difference was noted in the elderly. Despite more asthma-related symptoms, the ACT showed that elderly GP asthmatics used fewer rescue inhalers than elderly RS. Self-assessment was higher in elderly GP than elderly RS asthmatics. Adherence to therapy was better in elderly patients than young patients. Conclusions: Elderly asthmatics treated by GPs underestimated the severity of their asthma and asthmatics seen by GPs were undertreated. The results stress the need to engage patients in educational activities, to adhere to guidelines, and to improve the coordination between GP and RS.     

Are psychiatric disorders associated with worse asthma control and quality of life in asthma patients?

BACKGROUND: Achieving good asthma control has become the major goal of asthma treatment. Studies have reported a high rate of psychiatric disorders among asthma patients, though the impact of these disorders on asthma control and quality of life remains unexplored. This study evaluated the prevalence of psychiatric disorders in 406 adult asthma patients, and associations between psychiatric status, levels of asthma control, and asthma-related quality of life. METHODS: Consecutive asthma patients presenting to the asthma clinic underwent a brief, structured psychiatric interview, completed the Asthma Control Questionnaire (ACQ) and Asthma Quality of Life Questionnaire (AQLQ), and reported the frequency of bronchodilator use in the past week. All patients underwent standard pulmonary function testing. RESULTS: A total of 34% (n=136) of patients had one or more psychiatric diagnosis, including major depression (15%), minor depression (5%), dysthymia (4%), panic disorder (12%), generalized anxiety disorder (5%), and social phobia (4%). Though there were no differences in pulmonary function, patients with versus without psychiatric disorders had worse ACQ and AQLQ scores and reported greater bronchodilator use, independent age, sex and asthma severity. CONCLUSIONS: Results suggest that psychiatric disorders are prevalent among asthmatics and are associated with worse asthma control and quality of life. Physicians should be aware of the potential risk of poorer asthma control and functional impairment in this population.     

Misuse of corticosteroid metered-dose inhaler is associated with decreased asthma stability.

This study assessed whether the improper use of pressurized metered-dose inhalers (pMDIs) is associated with decreased asthma control in asthmatics treated by inhaled corticosteroids (ICS). General practitioners (GPs) included consecutive asthmatic outpatients treated by pMDI-administered ICS and on-demand, short-acting beta2-agonists. They measured an asthma instability score (AIS) based on daytime and nocturnal symptoms, exercise-induced dyspnoea, beta2-agonist usage, emergency-care visits and global perception of asthma control within the preceding month; the inhalation technique of the patient also was assessed. GPs (n=915) included 4,078 adult asthmatics; 3,955 questionnaires were evaluable. pMDI was misused by 71% of patients, of which 47% was due to poor coordination. Asthma was less stable in pMDI misusers than in good users (AIS: 3.93 versus 2.86, p<0.001). Among misusers, asthma was less stable in poor coordinators (AIS: 4.38 versus 3.56 in good coordinators, p<0.001). To conclude, misuse of pressurized metered-dose inhalers, which is mainly due to poor coordination, is frequent and associated with poorer asthma control in inhaled corticosteroid-treated asthmatics. This study highlights the importance of evaluating inhalation technique and providing appropriate education in all patients, especially before increasing inhaled corticosteroid dosage or adding other agents. The use of devices which alleviate coordination problems should be reinforced in pressurized metered-dose inhaler misusers.     

Asthmatics have more nocturnal gasping and reflux symptoms than nonasthmatics, and they are related to bedtime eating

OBJECTIVES: Certain pulmonary diseases are now recognized as possible complications of gastroesophageal reflux (GER) disease. To further clarify the relationship between GER and asthma, we determined the prevalence, nature, and patterns of reflux symptoms in consecutive asthmatics and a well-defined patient population control group. METHODS: Two hundred and sixty-one asthmatic outpatients with well-documented asthma were interviewed in person using an extensive questionnaire. To avoid selection bias, we (a) used no selection criteria other than asthma, (b) interviewed every identified asthmatic from either the outpatient general medical clinic or pulmonary clinic (and excluded the gastroenterology clinic), and (c) excluded asthmatics referred because of gastrointestinal symptoms. A control group comprised 218 consecutive outpatients chosen from the same general medical clinics in which the asthmatics were enrolled. Interviews were conducted by one of two investigators. RESULTS: The control and asthmatic groups were similar with regard to age, gender, ethnicity, and consumption of tobacco and alcohol. There were major significant differences between the asthmatics and controls with regard to the age of onset of pulmonary and reflux symptoms, prevalence of eating before bedtime, prevalence of reflux symptoms, the quality of reflux symptoms, and the factors that promote and relieve reflux symptoms. Heartburn, regurgitation, and dysphagia were present in 71%, 45%, and 22% of asthmatics compared with 51%, 30%, and 5% of controls (p < 0.001). Three times as many asthmatics as controls had heartburn occurring throughout the day and night (OR; 95% CI: 19.5; 4.5-85.7), and three times as many asthmatics as controls had sudden nocturnal awakening with reflux symptoms and reflux-associated pulmonary symptoms that occurred simultaneously with the reflux symptoms (p < 0.001). Within the asthma group, reflux symptoms were similar in those who required and those who did not require continuous bronchodilator therapy. In these asthmatics, however, those requiring continuous bronchodilator therapy (more severe asthma) developed pulmonary and GER symptoms at a significantly older age. Eating before bedtime was recognized by significantly more asthmatics than controls as a promoter of serious nocturnal GER symptoms (4.5; 2.7-7.7). In terms of patient awareness, one-third of the asthmatics with heartburn had previously considered a relationship between their reflux symptoms and their asthma. CONCLUSION: Compared to nonasthmatics, asthmatics have significantly more frequent and more severe day and night GER symptoms and significantly more of the pulmonary symptoms (nocturnal suffocation, cough, or wheezing) so often attributed to GER. The habit of eating before bedtime appears in asthmatics to have serious and life-threatening consequences.     

What Nurses in Primary Care Practices Know About Asthma Care: Results from a National Survey

Objectives: The purpose of this study was to characterize what nurses working in primary care settings know about asthma care. Current views on the care of persons with asthma suggest the need for sound knowledge of guideline-based care and a health care team that includes both physicians, nurses, and other providers. While there are reports of physician-related asthma care practices in the United States, there are few, if any, reports of nursing knowledge, attitudes, or beliefs about asthma care.

Methods: A national, randomly selected, representative sample of nurses working in ambulatory primary care settings was interviewed by telephone using a structured interview format.

Results: Of a sample of 80 nurses, less than 10% identified inflammation of the airways as the underlying condition that causes asthma symptoms. Fifty-one percent believed the underlying condition could be treated, while 44% believed only the symptoms could be treated, and 5% didn't know. Only 35% said they were aware of the National Heart, Lung, and Blood (NHLBI) asthma guidelines.

Conclusions: Nurses working in ambulatory primary care settings may lack sufficient knowledge to effectively teach and participate in asthma care.     

The effect of mode of data collection and of non-response on reported alcohol consumption: a split-sample study in Switzerland

Aims. To examine (a) effects of different modes of data collection on the reporting of alcohol consumption and non-response rate, and (b) differences in reported consumption between respondents and non-respondents. Design. Two versions of a health questionnaire survey were assigned to two random samples, one version to each sample. Version 1 consisted of a telephone interview without alcohol questions, followed by a mailed questionnaire with alcohol questions. Version 2 consisted of a telephone interview with alcohol questions, followed by a mailed questionnaire without alcohol questions. Setting. Participants were recruited randomly in eight Swiss cantons. Participants. Five hundred and thirty-seven (404) respondents to the telephone interview (and subsequent mailed questionnaire) with version 1, and 451 (360) with version 2. Measurements. Alcohol-use variables derived from a quantity-frequency measure. Results. Respondents to the mailed questionnaire (version 2) did not differ significantly in alcohol consumption from non-respondents. Response rate was not affected by inclusion of alcohol questions, but respondents asked by telephone about their alcohol use were more often abstainers and less often hazardous drinkers than respondents to the mailed question. Conclusion: The study gives no indication that interviews are refused because alcohol consumption is a questionnaire topic, but suggests that postal questionnaires give slightly greater disclosure of alcohol consumption.     

Swimming and asthma: factors underlying respiratory symptoms in competitive swimmers

Background: Swimming is recommended for asthmatics. However, many competitive swimmers report asthmatic symptoms. While some studies identify the swimming environment as a trigger for allergy and asthmatic symptoms, even more studies suggest swimming to be suitable for people with allergies and asthma. The factors behind the symptoms were studied first by determining the prevalence of asthma, allergy and self‐reported asthmatic symptoms in experienced Finnish swimmers and then by examining the relationships between the reported symptoms and the main triggering factors: medical history, environment and exercise intensity. Materials and Methods: Top swimmers (n = 332) of the Finnish Swimming Association registry (N = 4578) were asked to complete a structured questionnaire on their medical history, swimming background, swimming environment and symptoms in different swimming intensities. Two hundred experienced swimmers, 107 females and 93 males, with an average age of 18.5 [standard deviation (SD) = 3.0] years and a swimming training history of 9 (SD = 3.8) years completed the questionnaire. Results: Physician‐diagnosed asthma was reported by 32 swimmers (16%), including 24 (12%) with exercise‐induced asthma. Physician‐diagnosed allergy was reported by 81 (41%) swimmers. Asthmatic symptoms during swimming were described by 84 subjects (42%). Most symptoms occurred when swimming exceeded speeds corresponding to the lactic/anaerobic threshold. Family history of asthma was significant and the most important risk factor for asthmatic symptoms. Conclusions: The prevalence of asthma in swimmers was higher than in the general population but not different from that in other endurance athletes. Family history of asthma and increased swimming intensity had the strongest associations with the reported asthmatic symptoms. Please cite this paper as: Päivinen MK, Keskinen KL and Tikkanen HO.

Parent-reported symptoms may not be adequate to define asthma control in children

INTRODUCTION: Asthma guidelines have suggested that treatment decisions should be guided by indices of asthma control and not only by disease severity. In adults, symptom-based asthma control parameters have been shown to predict exacerbations and health care services use (HSU). We hypothesize that defining asthma control using parent-reported symptoms alone is not adequate in children. MATERIALS AND METHODS: Cross-sectional data from the population-based asthma in Canada study were reanalyzed. Random-digit dialing was used to produce the final sample, consisting of 1,001 asthmatics: 801 adults (aged 16+) and 200 children (aged 4-15) participating by parental proxy. Weighted frequencies of Canadian guideline defined asthma control parameters, perceived asthma control, HSU and medication use were calculated separately for adults and children. Stratified analyses compared HSU in controlled versus uncontrolled asthmatics. RESULTS: Over 90% of parents of asthmatic children believed their child's asthma to be controlled. Only 45% were actually controlled as defined by guideline parameters. Among controlled asthmatics, children reported higher HSU (32% reported 2+ health care encounters versus 17% of adults, P < 0.001). Irrespective of control and despite similar use of controller therapy, children reported a higher number of health care encounters than adults (any emergency department visits 37% vs. 24%, P = 0.00003; unscheduled doctor visits 59% vs. 36%, P < 0.00001). While reporting higher HSU, asthmatic children had less frequent episodes of excessive daytime symptoms than adults (29% vs. 49%, respectively, P < 0.0001). DISCUSSION: Current symptom-based asthma control parameters reported by parental proxy are likely poor predictors of asthma HSU and may not provide adequate asthma control estimates in children.     

Risk factors for intensive care in children with acute asthma

OBJECTIVE: A retrospective case-control study at Monash Medical Centre (MMC), a tertiary referral hospital in Melbourne, Australia, was conducted to identify risk factors associated with very severe asthma in paediatric patients. METHODOLOGY: Asthmatics admitted to an intensive care unit (ICU; n=52) were identified and considered to represent cases of very severe/near fatal asthma (NFA group). This group was compared to asthmatics who had been admitted on one occasion only to the emergency department at MMC (non-NFA controls, n=53). Patient files were examined and factors that may be linked to NFA were recorded. Information not on file was obtained from patients/parents during a structured telephone interview. Data for the two groups were compared, univariate and multivariate logistic regression analyses were performed, and odds ratios (OR) were calculated. RESULTS: Univariate analysis indicated that asthmatics with NFA were more likely to be older (P=0.01) and have a longer duration of asthma (P=0.02). They were also more likely to have hay fever (P=0.002; OR, 7.6), use inhaled corticosteroids (P=0.001), long acting beta(2) agonists (P=0.02), have an asthma management plan (P=0.006), and see a respiratory specialist (P=0.001). Parental smoking habits were not different between the groups. Multivariate logistic regression analysis identified male gender (P=0.05; OR, 5.7) and use of inhaled corticosteroids (P=0.07; OR, 7.2) as factors that may be predictive of NFA. CONCLUSIONS: This study identifies a number of factors associated with NFA; many are similar to those reported in adult patients. Asthma severity explains some findings, but the data also suggest that additional independent risk factors such as gender and duration of asthma may operate in children.

Underdiagnosis of Nocturnal Symptoms in Asthma in General Practice

Objective. To evaluate the prevalence of nocturnal symptoms in a large sample of asthmatic patients, and to assess the agreement between patients' complaints and general practitioners' (GPs') reports in primary care. Design. Cross-sectional survey involved 3,526 GPs and 751 specialists (pulmonologists and allergists) and included 13,493 patients with persistent asthma. Symptoms, treatment, and social and medical data were collected in real time by the patients and their GPs. Setting. France. Results. Prevalence of nocturnal symptoms was 60%. A total of 7,989 patients with nocturnal symptoms had complete data for both patients and GPs; 3,849 (48.1%) had perfect agreement between GP and their complaints for nocturnal symptoms (agreement group; [kappa = 1]); 3,376(42.2%) declared having no symptoms during the night, but these were detected by the GP during the visit (underestimated by patients and detected by GPs); 773(9.6%) declared having nocturnal symptoms, but these were not detected by GPs. Patients with a good agreement with their GP's opinion were significantly more frequently followed-up by a specialist than other patients (p = 0.002). Conclusions. Nocturnal symptoms appear to be underdeclared by patients. GPs should therefore systematically ask their patients about nocturnal symptoms to increase control of asthma and to adequately manage its treatment.
