OBJECTIVE: To examine the prevalence and management of asthma in adults and children in a population sample in eastern Australia. SETTING: A random sample of children from 33 primary schools in Sydney, Melbourne, Brisbane, and the Upper Hunter Valley (New South Wales), and their parents. DESIGN: A cross-sectional analytic survey of 8753 primary school children aged between 5 and 12 years, and their parents (n = 13,945 adults). Asthma prevalence and management practices were determined by parental responses to a questionnaire, and spirometry was performed in children with "probable asthma". RESULTS: Of 8753 children whose parents responded, the prevalence of current wheeze was 19.5% and diagnosed asthma was 17.1%. Of the children with "probable asthma", 30% had their lung function measured in the previous year, and 6% possessed both a peak flow meter and an action plan for their asthma. Undertreatment was likely, as preventive asthma medications (inhaled corticosteroids or sodium cromoglycate) were used regularly by only 25.5% of these children and by 44.3% of children who had asthma symptoms more than twice per week. Children with the diagnosis of asthma reported higher rates of preventive medication use and ventilatory function measurement than children with frequent symptoms without the diagnosis. In the 13,945 adults, the reported prevalence of asthma was 7%, of whom 39% were using preventive medications, 34% had their ventilatory function assessed in the previous year, and 7% had both a peak flow meter and an asthma action plan. CONCLUSIONS: The study illustrated the gap between the current level of asthma management in the community and the standards set by the Thoracic Society of Australia and New Zealand. Undertreatment and suboptimal management of asthma remain important problems in Australia. 相似文献

OBJECTIVE: To examine the relationships between ownership of written asthma action plans, asthma morbidity, use of devices, and patients' perceptions of their asthma management. DESIGN AND SETTING: A random population survey (in 1996) of the South Australian population aged 15 years or over, using interviewers to administer a questionnaire. PARTICIPANTS: People who reported that they had current, doctor-diagnosed asthma. MAIN OUTCOME MEASURES: Prevalence of written asthma action plans; night-time awakenings from asthma; ownership of peak flow meters; and people's perceptions of their asthma management. RESULTS: The ownership of asthma action plans by people with self-reported asthma was 33% and has declined since 1995 (42%; P < 0.001). Fifteen per cent were awakened weekly or more frequently by asthma symptoms. These people were more likely to have a peak flow meter and a written action plan, but less likely to consider they had been provided with enough information about their asthma, to feel comfortable managing their asthma, or to find it easy to see their doctor. Having a written asthma action plan was associated with regular corticosteroid use, understanding asthma, having enough information and owning a peak flow meter. CONCLUSIONS: Ownership of asthma action plans in South Australia is suboptimal. Before we develop new strategies to improve asthma outcomes, we must determine whether there is a need to target people with less severe asthma and/or improve the use of guidelines by health professionals. 相似文献

OBJECTIVES: To assess trends in the prevalence of self-reported doctor-diagnosed asthma, associated asthma related morbidity, and the uptake of written asthma action plans in South Australia, 1990-2001. DESIGN, SETTING AND PARTICIPANTS: Surveys by telephone interview of the South Australian population between 1990 and 2001, and interview of participants in their own homes by trained health interviewers. MAIN OUTCOME MEASURES: Asthma prevalence, percentage of patients with written action plans, and asthma associated morbidity. RESULTS: The reported prevalence of doctor-diagnosed asthma has increased from 8% (95% CI, 6.4%-9.6%) in 1990 to 12.8% (95% CI, 11.4%-14.2%) in 2001. Morbidity, as measured by wakening at night (daily or weekly) and days lost from normal activities because of asthma, has remained constant over the decade. The percentage of patients with written asthma action plans increased to a peak of 42.3% (95% CI, 40.3%-44.3%) in 1995, but then declined to 22.2% (95% CI, 20.7%-23.7%) in 2001. CONCLUSIONS: The prevalence of asthma has increased while morbidity has remained constant, indicating that the burden of asthma has increased. The associated decline in the percentage of patients with asthma action plans in recent years is cause for concern. 相似文献

The treatment preferences of 109 general practitioners (GPs) for childhood asthma were determined. Availability and adherence to clinical practice guidelines (CPG) for the treatment of childhood asthma was also assessed. Ninety eight (90%), 60 (55%) and 33 (30%) GPs considered nocturnal symptoms > 2 times/week, exercise induced wheeze and cough respectively as indications for preventer therapy. An oral preparation was preferred for relief medication [72 (66%) for 2-5 years, 60 (55%) for > 5 years]. An inhaled preparation was however preferred for preventer medication [60 (55%) for 2-5 years, 85 (78%) for > 5 years]. The oral form was more likely prescribed for asthmatic children 2-5 years (p < 0.001). Corticosteroids and ketotifen were the commonest inhaled and oral preventer treatment prescribed respectively. Only 36(33%) GPs have a CPG copy for reference. Children with asthma symptoms that require preventer therapy may not always be identified in general practice. The oral route remains important for asthma medication especially in young children. The accessibility to the CPG among GPs is disappointing. 相似文献

OBJECTIVE--To examine the relationship between patterns of use of inhaled beclomethasone dipropionate and the risk of fatal and near-fatal asthma. DESIGN--Nested case-control analysis of a historical cohort; a further analysis. SETTING--The 12,301 residents of Saskatchewan aged 5 to 54 years who were dispensed 10 or more asthma drugs from 1978 to 1987. PATIENTS--The 129 persons who experienced asthma death (n = 44) and near-death (n = 85) and their 655 controls matched as to age and date of entry into the cohort, with the additional matching criteria of at least one hospitalization for asthma in the prior 2 years, region of residence, and having received social assistance. MAIN OUTCOME--Life-threatening attacks of asthma defined as death due to asthma or the occurrence of hypercarbia, intubation, and mechanical ventilation during an acute attack of asthma. RESULTS--After accounting for the risk associated with use of other medications and adjustment for markers of risk of adverse events related to asthma, subjects who had been dispensed, on average, one or more metered-dose inhalers of beclomethasone per month over a 1-year period had a significantly lower risk of fatal and near-fatal asthma (odds ratio, 0.1; 95% confidence interval, 0.02 to 0.6). CONCLUSION--These data support recent guidelines from several countries that recommend the use of inhaled corticosteroids in moderate and severe asthma. 相似文献

Utilization of the "Smokescreen" smoking-cessation programme by general practitioners and their patients 总被引:1,自引:0,他引:1
R C Copeman R J Swannell D F Pincus K A Woodhead 《The Medical journal of Australia》1989,151(2):83-87
General practitioners have been encouraged to be more active in helping their patients to stop smoking. A number of research studies overseas and in Australia has reported that they can be effective in this form of health promotion. The "Smokescreen" programme is an intensive, structured antismoking intervention that was developed for use by general practitioners in Australia. To monitor the effect of this programme, general practitioners who had attended workshops on the use of the programme were contacted 12 months later to find out what use they had made of the programme, and how effective it had been. Only 18 of the 38 doctors who initially agreed to cooperate in the study had recruited smokers to the programme and had kept records of their progress. These 18 doctors had recruited 121 smokers in the 12-month period: only 7% (approximately) of all their patients who smoked. Of these, 29 (24%) patients reported that they had stopped smoking. Reasons that were given by doctors for their inability to use the programme as fully as they had hoped included the difficulty in recruiting smokers, a lack of time, and a low rate of return by the patients for follow-up visits. These results suggest that while general practitioners should be encouraged to give brief antismoking advice, general practice may not be a suitable location for more-intensive antismoking programmes. Limited health-promotional funds may be deployed better in general community awareness and mass-media programmes. 相似文献

BACKGROUND: This study addressed symptoms' profile, severity and determinants of asthma control in school-aged patients (5-14 y) across Lebanon. METHODS: It is a cross-sectional study, applied on school children with physician-diagnosed asthma (PDA), divided into two groups: those who were on controllers (C+) and those who were not (NC). RESULTS: Out of 5544 children, 275 (4.96%) had PDA. The C+ group (32.7%) had higher mother's education than the NC group (45.9%) (p = 0.037). NC children were more frequently found in public versus private schools (p = 0.0001). Higher frequencies of regular visits to the doctor were noted in the C+ compared to NC group. In C+ group, 90% were on reliever and controller, and 10% just on one controller. A trend for more severity in the C+ group was noted compared to the NC group. An impact of asthma on daily activities was reported by 40% in the C+ group versus 34% in the NC group. CONCLUSION: Treatment of PDA in 5-14 y school children was quite adapted according to the recommendations. However, total control was reported in low percentages of patients reflecting universal discrepancy between evidence base medicine and real life. 相似文献

Deaths from asthma in Victoria: a 12-month survey 总被引:9,自引:0,他引:9
The circumstances surrounding the death of all patients who died from asthma in the State of Victoria over a 12-month period from May 1, 1986 were investigated. Data were collected using an interviewer-administered questionnaire as soon as practicable after registration of the death. In 168 cases asthma was considered to be the cause of death and adequate data were obtained in 163; 75 of these were male (74 over 60 years of age). Thirteen per cent had a history of trivial or mild asthma, 22% of moderate and 65% of severe asthma. Thirty-four per cent had not been limited at all or only by active sport, while 39% had had no previous hospital admission for asthma. In only 18% had there been a previous admission to an intensive care unit. Forty-seven per cent were taking inhaled beclomethasone or sodium cromoglycate regularly and 27% were taking corticosteroids by mouth regularly. Death occurred outside hospital in 150 of 163 subjects. In the final attack 58% had a sudden onset and collapsed within minutes, 20% were found dead and 27% had an acute progression of an established attack. Twenty-nine per cent of the deaths were assessed as preventable: preventable factors included inadequate assessment or therapy of prior asthma (35%), poor compliance with therapy (33%) and delay in seeking help (43%). As a significant number of subjects in this survey could not be classified as "high risk", it is important that clinicians ensure that all patients are aware of optimal maintenance management and have a clear individualized plan of what to do in the event of deteriorating asthma. 相似文献

OBJECTIVE: To explore the reasons why individuals recurrently present with asthma to hospital emergency departments. DESIGN: A predominantly qualitative study in which participants were interviewed in-depth about their asthma. Data on medication use, respiratory health and asthma knowledge were also collected, and asthma severity was determined from medical records. SETTING: A tertiary teaching hospital and a suburban hospital emergency department (ED) from 1 March to 30 April 2000, and a rural hospital ED from 1 July to 31 August 2000. PARTICIPANTS: The participation rate was 32% of an initial 195 ED attendees (183 of whom were eligible) aged 18-70 years: 32 had presented to an ED for asthma care on more than one occasion over the preceding 12 months (reattendees), and 29 were non-reattendees. RESULTS: Two-thirds (22/32) of reattendees had chronic severe asthma and presentation to ED was deemed appropriate for 18 of these, indicated by recurrent severe asthma attacks despite seeking prior medical intervention. Reasons for re-presentation identified in a third of all reattendees included poor asthma knowledge, and financial and other barriers to medication use. CONCLUSIONS: We identified potentially preventable issues in about a third of patients (most of whom had mild to moderate asthma) who recurrently presented to EDs for treatment. The remainder of the participants sought emergency asthma treatment appropriately after failing to respond to medical care, and this was frequently in accordance with their asthma management plans. 相似文献

We have assessed the effects of intervention on medication compliance in asthmatic children. The intervention comprised both written information about the medications and behavioural strategies effected by the physician. Children were assigned at random to either control (received no intervention) or test (received the intervention) groups. Compliance was assessed by questionnaire. The mean compliance for the test (78.0%; n = 93) and for the control (54.5%; n = 103) groups differed significantly (P less than 0.001; Mann-Whitney U-test). The test group had a better knowledge of asthma and of the medications, and was more satisfied with the physician and with the regimen than was the control group. These variables were also related to good compliance. This study demonstrates that a programme of intervention can significantly improve medication compliance and can be accompanied by increases in the knowledge of, and satisfaction with, treatment. 相似文献

The cost of asthma in New South Wales 总被引:5,自引:0,他引:5
OBJECTIVE: To determine the economic cost of asthma to the New South Wales community. DESIGN: Direct costs (both health-care and non-health-care) plus indirect costs (loss of productivity) were estimated from various sources to assess retrospectively the dollar costs of asthma. Intangible costs (such as quality of life) were not included. SETTING: Estimates of costs were made at all levels of medical care of asthma patients, including inpatient and outpatient hospitalisations, emergency department visits, and visits to general practitioners and specialist physicians, plus costs of pharmaceuticals, nebulisers and home peak-flow monitoring devices. The cost of time lost by the patient attending for medical visits and loss of productivity due to absence from employment as a result of asthma were also included. RESULTS: The total cost of asthma in New South Wales was $209 million in 1989. This was made up of $142 million in direct health-care costs, $19 million in direct non-health-care costs and $48 million in indirect costs. CONCLUSION: Although we believe that our estimate is an underestimate of the true dollar cost of this disease to the community, it represents $769 per asthmatic person per year, assuming a current prevalence rate for asthma in New South Wales of 6%. The cost effectiveness of any new treatment of asthma should be estimated to ensure that the economic cost to the community does not rise unnecessarily. 相似文献

Background
Internationally, many children with asthma are not attaining achievable asthma control.Aims
To examine the prevalence of asthma in teenagers in four midland counties, their asthma control and the barriers, if any, to gaining control of asthma.Methodology
International Study of Asthma and Allergies in Children (ISAAC) methodology was used in a survey of Junior Cycle Year 2 second-level students.Results
The prevalence of “wheeze ever” was 49.8%, “wheeze in the last 12 months” was 32.6% and “asthma ever” was 23.5%. Of teenagers with current asthma, 96% had evidence of sub-optimal asthma control during the previous year. For the majority of the teenagers with asthma, treatment was not guideline concordant; infrequent lung function testing, insufficient review after acute care and poor use of written asthma action plans. Barriers included lack of awareness of need for treatment.Conclusions
If asthma guidelines are implemented fully, these children may experience better health. 相似文献18.

BackgroundAirway hyperresponsiveness (AHR) is a characteristic feature of bronchial asthma and is diagnosed using direct and indirect bronchoprovocation tests. The diagnosis of AHR is a challenge in symptomatic patients with a normal baseline prebronchodilator spirometry and postbronchodilator spirometry. Exercise-induced asthma or exercise-induced bronchoconstriction (EIB) is a distinct form of AHR. There is no single test that is sufficient to exclude AHR in symptomatic military personnel with normal spirometry. This study was conducted to compare the diagnostic value of indirect bronchoprovocation test using inhaled adenosine monophosphate (AMP) and exercise challenge test (ECT) in the diagnosis of EIB.MethodsA crossover study was conducted with consecutive sampling of patients presenting with symptoms suggestive of asthma and with normal spirometry results who were subjected to both ECT and bronchoprovocation test using inhaled AMP on separate days.ResultsForty participants were recruited (the mean age: 25 yrs, 100% male). The commonest presentation was breathlessness on exercise (55%). With exercise alone, 40% tested positive for AHR, while with AMP alone, the positivity increased to 53%, and the difference was statistically significant (p= 0.03). Exercise alone failed to detect 8 cases that tested positive for AHR by inhaled AMP challenge.ConclusionIndirect bronchoprovocation test using inhaled AMP may be used to diagnose AHR in conditions in which exercise challenge testing is not available or the patient is unable to complete ECT. 相似文献

Four hundred and twenty-one subjects who attended metropolitan pharmacies in Melbourne that were selected at random were surveyed about the characteristics of, and their knowledge about, their asthma. An unexpectedly-high morbidity was found among 232 persons with asthma, who were aged between 16 years and 75 years. Forty per cent of subjects had been hospitalized at least once for asthma and 15% of subjects were taking maintenance corticosteroid agents by mouth. Twenty per cent of subjects currently were smoking cigarettes (15 cigarettes per day on average). When knowledge of asthma was examined by a questionnaire, the median score of questions that were answered correctly was less than 50% of the total. The best knowledge scores were associated with subjects: who had been exposed in the past to information about asthma; who had attended a private medical specialist; who were non-smokers; and who had achieved the highest levels of schooling. Among the serious misconceptions which were evident in the areas of use of medication were: that sustained-release theophylline agents acted quickly during acute attacks of asthma (62% of subjects); that antihistamine agents should be taken as soon as possible during an asthma emergency (72% of subjects); that six inhalations of beclomethasone were advisable during an asthma emergency (49% of subjects); that systemic corticosteroid agents were effective within 20 minutes of administration (87% of subjects); and that deaths of asthma usually were due to precipitous attacks without time for any intervention (73% of subjects). Only 42% of subjects considered that up to six puffs at once of a beta-agonist aerosol for an asthma emergency may be appropriate. The identification of such misconceptions is quite practical during routine consultations. The correction of such misconceptions may improve the morbidity and mortality that is due to asthma. 相似文献
