Can telehealth deliver for rural Scotland? Lessons from the Argyll & Bute Telehealth Programme.

Policy-makers consider telehealth to be a potential solution to delivery of care in rural Scotland. Telehealth can support patients in the community and may reduce emergency admissions to hospital. The Argyll & Bute telehealth initiative, which commenced in 2007, trialled home telehealth monitoring of patients with chronic obstructive pulmonary disease (COPD), and community- and surgery-based monitoring of general wellbeing and hypertension. An evaluation in 2010 assessed staff and patient satisfaction by questionnaire, impact on hospital and general practice attendance by case record review and detailed opinions on the programme by qualitative interviews with key staff. Home monitoring for COPD was associated with high levels of patient satisfaction and a reduction in hospital admissions and other health service contacts. Delays in implementation and some technical challenges compromised evaluation of the surgery and community initiatives. Patients and staff were generally enthusiastic but also identified potential barriers to development. This paper describes the implementation and outcomes of the initiative and identifies issues that clinicians embarking on telehealth programmes must consider: technical factors; governance and security; staff profiling and training; clinical outcomes; and scalability.

More than health: the added value of health services in remote Scotland and Australia.

Health services are suggested to contribute to remote communities in the ways that extend beyond healthcare delivery. This international multiple case-study research provides qualitative evidence of the social, economic and human contributions (the 'added-value') that may be lost should remote communities lose in-situ health provision. We present a typology of added-value contributions that differentiates institutional aspects (residing in buildings, or embodied in the specific status, capabilities and skills of health professionals) and individual aspects (attributable to health professionals' unique personalities and choices). This typology has relevance for communities, policymakers and managers when considering the impacts of potential service changes.

Screening for abdominal aortic aneurysm in a geographically isolated area.

BACKGROUND: Screening for abdominal aortic aneurysm has been shown to reduce aneurysm-related mortality, but the applicability of the results to the whole of the UK has been questioned. This study examined screening in a remote and rural area. METHODS: Over 3 years, men aged 65-74 years were offered screening in the community by ultrasonography, usually in general practitioner surgeries. Men with an aneurysm were rescanned at intervals or assessed for surgery. The screening and hospital costs of the programme were calculated. RESULTS: Some 9323 men were offered screening of whom 8355 (89.6 per cent) attended. Uptake was high in all areas. A total of 430 scans (5.1 per cent) were abnormal; 40 men had an aneurysm greater than 55 mm in diameter. Twenty further men had an aorta that enlarged to greater than 55 mm during follow-up. A total of 54 men had elective repair with one death (mortality rate 2 per cent). The cost of screening alone was 16 pound per invitation and the overall cost of the programme, including surgery, was 58 pound per invitation. CONCLUSION: Screening for abdominal aortic aneurysm can be carried out in a remote and rural area with high uptake, acceptable clinical results and at no greater cost than in more densely populated areas.

Rural health care in the U.K.: a rapidly changing scene.

Delivery of medical, nursing, and other health-related services in remote and rural areas is challenging. Historically, in the U.K., rural health care delivery has focused on medically qualified general practitioners or family physicians providing primary care services, together with isolated small hospitals providing limited specialist services such as surgery, obstetrics, and internal medicine. However, three recent developments in Europe and the U.K. will change these traditional practices. These are implementation of the European Working Time Directive, constraints related to "clinical governance", and a new contract for general medical practitioners. Delivery of services in rural areas currently faces potential conflict between national standard setters and local practicalities, and re-design of services is required. Public engagement with redesign is essential, but the outcome may be dependent on the methods used. Evaluation of new services is essential. This article gives brief examples of: two public engagement processes (a survey and a discrete choice experiment), two redesign experiments related to screening for aortic aneurysm and consultant-supported care in an island hospital, and some issues concerning the use of new technologies (telemedicine and telephone triage) in remote communities. Future implications are discussed.

Consultant supported intermediate care--a model for remote and island hospitals.

INTRODUCTION: Providing local consultant-delivered hospital services in remote and island communities in the United Kingdom is increasingly problematic due to difficulties with recruitment and retention of staff, statutory restrictions to hours worked by health professionals and the expectation each clinician must manage an externally defined volume of cases to maintain clinical standards. This article describes a before-and-after evaluation of a novel method of providing consultant support for acute internal medicine to an island grouping off the Scottish coast. Under the scheme, local GPs provided acute medical care of inpatients. A consultant general physician was appointed in a district general hospital on the mainland, approximately 100 miles from the island group, to provide a lead clinician role for inpatient services at the island hospital, visiting the island on a twice-monthly basis, undertaking educational sessions and developing local guidelines and care pathways for the management of individual medical conditions. In addition, two junior doctors were appointed to the island hospital to support inpatient care. METHODS: A prospective recording system for case mix was established with agreed evidence-based protocols, developed as integrated care pathways (ICP), for indicator conditions. General case mix was determined during two 6-month periods, June-November 2001 and June-November 2002, before and after implementation of the new arrangements. Performance against an ICP for management of suspected cardiac chest pain was evaluated in detail, examining the process of management, clinical outcome and economics. Data from the clinical literature were used to estimate the potential health gains from observed changes in clinical practice. RESULTS: Total admissions rose by 25% in the second time period, with particular increases noted for cardiovascular, cerebrovascular disease, and cancer. Total air ambulance transfers between the islands and the mainland within these time periods increased by 31%, from 88 to 115 transfers. Recording specific details from the history and frequency of appropriate blood investigations increased and initial steps in management changed considerably after introduction of the ICP. The number of transfers to the mainland teaching hospital increased from 3/37 (8%) in 2001 to 15/56 (27%) in 2002. Based on an estimated 100 patients per year, of whom 15 would receive thrombolysis, total additional patient costs would be 64,000 pounds sterling. The annual cost of the additional resource input into the medical service was 148,000 pounds sterling. Approximately 16 adverse events would be avoided at a combined cost of 212,000 pounds sterling (148,000 pounds sterling direct costs of intervention + 64,000 pounds sterling additional treatment costs) or 13,250 pounds sterling per event avoided. This is a conservative estimate of benefit as all the direct costs of the intervention have been included. CONCLUSIONS: This study shows that appropriate standards of care can be delivered in the setting described. Costs of care increased, but the level of service provided increased concomitantly, and the health benefits were achieved at costs that compare favourably with other interventions recommended by health technology assessment groups. An estimate of notional costs involved in alternative models for the delivery of hospital medical services in a remote area suggests that costs would be similar for a three-consultant service, the present model, and a triage and transfer system. In the future, the models chosen by remote and island communities and healthcare providers are therefore likely to be determined by viability, sustainability and public acceptability rather than cost. Our study indicates that consultant supported intermediate care is a viable model.

Relationship between birth weight and adult lung function: controlling for maternal factors.

BACKGROUND: There is conflicting evidence on the "fetal origins hypothesis" of association between birth weight and adult lung function. This may be due to failure to control for confounding maternal factors influencing birth weight. In the present study access to birth details for adults aged 45-50 years who were documented as children to have asthma, wheezy bronchitis, or no respiratory symptoms provided an opportunity to investigate this association, controlling for maternal factors. METHODS: In 2001 the cohort was assessed for current lung function, smoking status, and respiratory symptoms. Birth details obtained from the Aberdeen Maternity and Neonatal Databank recorded birth weight, gestation, parity, and mother's age and height. RESULTS: 381 subjects aged 45-50 years were traced and tested for lung function; 323 (85%) had birth details available. A significant linear trend (p<0.01) was observed between birth weight and current forced expiratory volume in 1 second (FEV(1)) and forced vital capacity (FVC) values (adjusted for height, age, sex, weight, deprivation category (Depcat), childhood group, and smoking status). This trend remained significant after adjusting birth weight for gestation, parity, sex, mother's height and weight (p = 0.01). The relationship between birth weight and FEV(1) and FVC remained significant when adjusted for smoking history. There was no association between birth weight and current wheezing symptoms. CONCLUSION: There is a positive linear trend between birth weight, adjusted for maternal factors, and lung function in adulthood. The strength of this association supports the "fetal origins hypothesis" that impairment of fetal growth is a significant influence on adult lung function.

Stroke outcomes in Northern Scotland: does rurality really matter?

INTRODUCTION: Stroke is the third leading cause of death in Scotland after coronary heart disease and cancer and is a major cause of long-term disability. There is evidence in other clinical conditions such as asthma, diabetic retinopathy, and cancer that rural residents may have poorer outcomes, due to relative inaccessibility of health-service provision or because the disease is at a more advanced stage at diagnosis. However, the evidence-base for stroke care and outcomes in remote and rural areas is small and the subject matter is under-researched. This study was designed to examine, over a one-year period, the incidence and outcome of stroke occurring in the Highlands and Islands of Scotland, a large geographical area with many rural and remote settlements. The study explored whether stroke care and outcome was affected by remoteness and rurality. METHODS: The study was a prospective, community-based, observational survey. Patients in Highland and the Islands (Orkney, Shetland and the Western Isles) suffering first-ever stroke during a 12-month period (from 1 May 2001 to 30 April 2002) were included. All practitioners from health and social care sectors, residential homes, voluntary and charitable organisations were encouraged to notify the researchers of any individual they suspected or knew had a first-ever stroke within the designated time period. Data on 'limitation in activities' (formerly 'level of disability') and service provision were collected using questionnaires and proformas at 1, 3 and 6 months post-stroke from several sources. These included individual patients and carers, health and social care professionals, residential homes, voluntary organisations, and charitable organisations. The analysis focused on location at time of follow up, limitation in activities and service provision. Outcomes were compared across different settlement categories. Settlements were classified as urban/accessible, remote rural and very remote, based on the Scottish Household Survey. RESULTS: In all, 303 patients with a suspected first-ever stroke were notified to the study. The resulting crude incidence of reported stroke was 1.1 per 1000. From the notifications, 239 patients were sent a consent form, of whom 118 agreed to participate in the study. The final dataset, after exclusions for incorrect diagnosis, deaths and other reasons, was derived from 85 patients. Among these, patients from remote rural and very remote settlements were over-represented, when compared to all patients notified. The majority of patients returned home from acute hospitals during the study period and the likelihood of returning home was not related to settlement category. However, a greater proportion of patients in remote rural settlements were admitted to community hospitals and remained there at 6 months. Approximately two-thirds had some degree of disability (or limitation in activities) after their stroke. One-third of patients classed themselves as independent across all time points. Overall, the Barthel Index score increased over time (ie, patients experienced a reduction in disability) with the average score at 1 month post-stroke being 82.5 (range 0-100), at 3 months 85 (range 5-100), and at 6 months 90 (range 5-100). Uptake of services was similar across all settlement categories, with low levels of use at 6-months post-stroke. In particular, few patients used social-support and stroke-specific services, for example Chest, Heart and Stroke Scotland, and Stroke Nurse services. The proportion of patients using any service at 1, 3 and 6 months did not differ between settlement categories. Rural patients did not therefore appear disadvantaged in service provision. CONCLUSIONS: The low incidence of reported stroke may have been due to a number of reasons including: death prior to notification; diagnostic uncertainty; stroke severity--failure to notify very mild or very severe stroke cases; and inadequate reporting of patients managed at home. The greater proportion of patients in remote rural settlements being admitted to community hospitals and remaining there at 6 months may reflect greater availability of community hospital places in this settlement category, but may also be influenced by stroke severity. The low uptake of rehabilitation and support services generally, combined with the relatively poor functional outcome of our patients, suggests that there may be an unmet need for rehabilitation. However, rural patients did not appear specifically disadvantaged. Our study indicates that patients developing a first-time stroke in remote and rural areas of the Highlands and Islands of Scotland are not disadvantaged compared to those in urban/accessible areas, with respect to outcome or to the utilization of health and social care services. However, functional outcomes could be improved for patients in all settlement categories.

A randomised trial of self-management planning for adult patients admitted to hospital with acute asthma.

BACKGROUND: There is still debate over the benefit of self-management programmes for adults with asthma. A brief self-management programme given during a hospital admission for acute asthma was tested to determine whether it would reduce readmission. METHOD: A randomised controlled trial was performed in 280 adult patients with acute asthma admitted over 29 months. Patients on the self-management programme (SMP) received 40-60 minutes of education supporting a written self-management plan. Control patients received standard care (SC). RESULTS: One month after discharge SMP patients were more likely than SC patients to report no daytime wheeze (OR 2.6, 95% CI 1.5 to 5.3), no night disturbance (OR 2.0, 95% CI 1.2 to 3.5), and no activity limitation (OR 1.5, 95% CI 0.9 to 2.7). Over 12 months 17% of SMP patients were re-admitted compared with 27% of SC patients (OR 0.5, 95% CI 0.3 to 1.0). Among first admission patients, OR readmission (SMP v SC) was 0.2 (95% CI 0.1 to 0.7), p<0.01. For patients with a previous admission, OR readmission was 0.8 (95% CI 0.4 to 1.6), p=0.6. SMP patients were more likely than SC patients to be prescribed inhaled steroids at discharge (99% v 92%, p=0.03), oral steroids (98% v 90%, p=0.06), and to have hospital follow up (98% v 84%, p<0.01) but adjustment for these differences did not diminish the effect of the self-management programme. CONCLUSIONS: A brief self-management programme during hospital admission reduced post discharge morbidity and readmission for adult asthma patients. The benefit of the programme may have been greater for patients admitted for the first time. The programme also had a small but significant effect on medical management at discharge.

Coincidence of immune-mediated diseases driven by Th1 and Th2 subsets suggests a common aetiology. A population-based study using computerized general practice data.

BACKGROUND: The recent rise in the prevalence of immune-mediated diseases has been attributed to environmental factors such as a lack of microbial challenge, or dietary change, that deviate the overall balance between mutually antagonistic subsets of T helper (Th) cells. OBJECTIVE: An alternative proposal is that recent environmental changes have resulted in an immune system that is more likely to produce both Th1 and Th2 responses against benign antigens. The prediction of this hypothesis, that Th1 and Th2-mediated diseases are not mutually exclusive, and may be positively associated, is tested here in a whole population. METHODS: Data from General Practices participating in the Scottish Continuous Morbidity Recording (CMR) project were used to determine the coincidence of the major Th2-mediated atopic diseases; asthma, eczema and allergic rhinitis, with the Th1-mediated autoimmune conditions; type I diabetes, rheumatoid arthritis and psoriasis. We also identified the prescription rates of inhaled therapy for asthma in patients with Th1-mediated disease. RESULTS: There was a significant increase in the risk of presenting with a Th1-mediated autoimmune condition in patients with a history of allergic disease (standardized prevalence ratio (95% confidence interval) 1.28 (1.18-1.37)). Likewise, the standardized prevalence ratios of presenting with either eczema (1.67 (1.48-1.87)) or allergic rhinitis (1.22 (1.02-1.44)) were significantly increased in subjects with a history of Th1-mediated disease. There was a particularly strong association between current psoriasis and current eczema (standardized prevalence ratio ofpsoriasis in subjects with eczema 2.88, 95% confidence interval (CI) 2.38-3.45). There was also a significant increase in prescriptions for inhaled asthma therapy in patients with Th1 disease. CONCLUSION: It is concluded that Th1- and Th2-mediated diseases are significantly associated in a large General Practice population. This finding supports the proposal that autoimmune and atopic diseases share risk factors that increase the propensity of the immune system to generate both Th1- and Th2-mediated inappropriate responses to non-pathological antigens.

Community mortality after ruptured abdominal aortic aneurysm is unrelated to the distance from the surgical centre.

BACKGROUND: Ruptured abdominal aortic aneurysm (RAAA) carries a high community mortality. Raigmore Hospital, Inverness serves Highland Region, an area the size of Wales with a population of 204,000. The aim of this retrospective review was to determine the community mortality and hospital mortality rates from RAAA in Highland Region and to assess whether distance travelled had any significant impact on survival. METHODS: Data were retrieved from hospital records, the Registrar General for Scotland and the Information and Statistics Division of the National Health Service in Scotland about patients diagnosed with RAAA between 1992 and 1999. RESULTS: Of 198 patients with RAAA, 131 (66 per cent) were transferred to Raigmore Hospital while the other 67 (34 per cent) died in a community hospital or at home. Of those reaching Raigmore 109 (83 per cent) had surgery, of whom 65 (60 per cent) survived. The overall community mortality rate was 67 per cent while the hospital mortality rate was 50 per cent. The hospital and community mortality rates for patients living within 50 miles of Raigmore Hospital were 60 and 67 per cent respectively, compared with 26 and 68 per cent for those living more than 50 miles away. CONCLUSION: Distance from Raigmore Hospital had no significant impact on community mortality from RAAA.

Patient weighting of importance of asthma symptoms.

BACKGROUND: Quality of life measures are increasingly important in evaluating outcomes in asthma. If some asthma symptoms are more troublesome to patients than others, this may affect their contribution to outcome measures. This study was designed to assess the relative importance of common symptoms in adults with asthma. METHODS: A postal survey using conjoint analysis was performed in 272 adults attending hospital outpatient clinics with moderately severe asthma. Patients were asked to chose between "symptom scenarios" offering different combinations of levels of five common asthma symptoms over one week. Two versions of the questionnaire were used with identical scenarios presenting symptoms in different orders. Different patients answered the two versions. Regression analysis was used to calculate symptom weights for daytime cough, breathlessness, wheeze and chest tightness, and sleep disturbance. RESULTS: Symptom order, percentage predicted peak expiratory flow (PEF), and symptoms in the week before the survey did not influence the choice of scenario. In both questionnaires patients were more likely to choose scenarios with low levels of cough and breathlessness than low sleep disturbance, wheeze or chest tightness. Regression weights for cough (-0.52) and breathlessness (-0.49) were twice those of wheeze (-0.25), chest tightness (-0.27), and sleep disturbance (-0.25). For 12% of patients cough dominated patient preferences, regardless of all other symptoms. Age was inversely related to weight given by patients to breathlessness. CONCLUSIONS: The prominence of cough among other asthma symptoms was unexpected. Daytime cough and breathlessness had greater impact for patients than wheeze or sleep disturbance. Age influenced symptom burden, with younger patients giving greater weight to breathlessness than older patients. Conjoint analysis appears to be a useful method for establishing the relative importance of common symptoms.

Fatal haemorrhage from aortic dissection following instillation of intrapleural streptokinase.

A patient is described who suffered fatal haemorrhage following intrapleural streptokinase for treatment of a presumed empyema. Autopsy revealed an unsuspected abdominal aortic dissection with extension of blood clot into the thoracic cavity. The importance of precise diagnosis of empyema and potential risks associated with intrapleural streptokinase are discussed.

Childhood exposure to infection and risk of adult onset wheeze and atopy.

BACKGROUND: The prevalence of asthma and allergic diseases in children and young adults is inversely associated with family size. It has been suggested that more frequent exposure to infections in a large family group, particularly those spread by the faecal-oral route, may protect against atopic diseases, although not all published data support this hypothesis. Whether similar considerations apply to adult onset wheeze is unknown. The relationship between adult onset wheezing and atopy measured in adulthood and childhood exposure to a range of infections was investigated. METHODS: A nested case control study of participants in a 30 year follow up survey was conducted. Questionnaire data on childhood infections had been obtained in a 1964 survey. In 1995 a further questionnaire on respiratory symptoms and other risk factors for wheezing illness was administered, total IgE, skin and RAST tests were performed, and serum was stored. In 1999 serological tests for hepatitis A, Helicobacter pylori, and Toxoplasma gondii were performed on the stored samples. Information from the 1964 questionnaires was available for 97 cases and 208 controls and serological tests were obtained for 85 cases and 190 controls. The potential risk factors were examined for all cases, those who reported doctor diagnosed asthma, those who described persistent cough and phlegm with wheeze, and subjects stratified by atopic status. RESULTS: The sibship structure was similar in cases and controls. In univariate analysis of all cases, childhood infections reported by parents as acquired either before or after the age of three years did not influence case:control or atopic status. Seropositivity was also similar for all cases and controls, but cases in the subgroup with chronic cough and phlegm were more likely to be seropositive for hepatitis A and H pylori. Seropositivity was unrelated to atopic status. In multivariate analyses both the effect of having two or more younger siblings (OR 0.1, 95% CI 0.03 to 0.8) and of acquiring measles up to the age of three (OR 0.2, CI 0.03 to 0.8) were significantly related to a lower risk of doctor diagnosed asthma. CONCLUSIONS: In these well characterised subjects, exposure to infections as measured by parental reports obtained at age 10-14 years and by serological tests obtained in adulthood did not influence the development of wheezing symptoms or atopic status in adulthood. However, early exposure to measles and family size may be associated with a lower risk of adult onset doctor diagnosed asthma.

Severe alpha1-antitrypsin deficiency and pregnancy.

This case study describes a successful pregnancy in a 27-yr-old patient with severe emphysema, secondary to alpha1-antitrypsin deficiency, genotype PiZZ. Despite significant respiratory compromise, more severe than previously reported, no complications ensued. Maternal pulmonary function did not deteriorate significantly until the 32nd week of pregnancy, with an elective Caesarean section being performed during the 37th week. This experience suggests that even severe maternal airflow obstruction is, in itself, not an absolute contra-indication to pregnancy. Pre-pregnancy multidisciplinary counselling is likely to be helpful in these patients, including frank discussion on the risks of pregnancy, the prospects of successful completion and the mother's future prognosis in relation to caring for the child.

Asthma, wheezy bronchitis, and atopy across two generations.

Although the prevalence of asthma has risen significantly during the last 30 yr, it is not clear whether this has occurred primarily in persons with a strong genetic predisposition to asthma and atopy or in other sections of the population. We have investigated outcomes in children of nuclear families selected through probands previously characterized by studies in 1964 and 1989 as having histories of persistent childhood onset atopic asthma, transient childhood wheezy bronchitis, and no respiratory symptoms or atopy. Children of wheezy bronchitic probands had a significantly better symptomatic outcome in adolescence, irrespective of the atopic status of the parent proband, than do children of either asthmatic or asymptomatic probands, suggesting that this may be a syndrome that shows familial aggregation and is distinct from asthma. Total serum IgE levels were significantly lower in children of nonatopic asymptomatic probands, including those with wheezing symptoms. In contrast children of nonatopic asymptomatic probands had an unexpectedly high prevalence of wheezing (33%), positive skin prick tests (56%), and positive specific serum IgE to common allergens (48%) that was similar to that found in children of atopic asthmatic probands. Our findings support the concept that wheezy bronchitis is a separate syndrome from atopic asthma. High total serum IgE levels within our population appear to be an important marker of genetic predisposition to atopy. Our data also suggest that much of the increase in asthma prevalence is associated with specific IgE sensitization and is occurring in persons previously considered to be at low risk of developing asthma or atopy.

Domiciliary nebuliser therapy--a valuable option in chronic asthma and chronic obstructive pulmonary disease?

Domiciliary nebulisers are in widespread use for patients who have severe chronic airways disease, both asthma and chronic obstructive pulmonary disease (COPD). We report a study of the use of domiciliary nebulisers designed to assess practical problems and the value of such therapy in preventing hospital admissions. A total of 405 patients underwent a structured interview at home and their case records were reviewed. Technical performance of the nebuliser compressors was assessed. The mean (SD) age of those interviewed was 64.5 (12) years. 185 patients had a physician diagnosis of asthma, and 208 had COPD. 87% patients used their nebuliser at least once daily. Side effects, reported by 54%, were related to frequency of use and commoner in younger patients. 29 subjects (7%) died within 2 years of receiving their nebuliser. Among the survivors, the 2 year periods before and after supply of the nebuliser were compared. The percentage of patients requiring hospital admission for exacerbations of lung disease fell from 56% to 46% (p < 0.01) but the number and duration of admissions was unchanged. Those whose admission duration increased had more severely impaired spirometry when the nebuliser was supplied and had lower activity scores and higher breathlessness scores at the time of interview indicating more severe disease. Approximately half of the compressors were malfunctioning and patients' understanding of the principles of nebuliser treatment was poor. The provision of domiciliary nebuliser can influence hospital admission in patients with obstructive airways disease. There is also a need for improved patient education and for technical support which may require the development of a nurse-run nebuliser service.

Risk factors for adult onset wheeze: a case control study.

Risk factors associated with adult onset wheeze were examined in a case control study of subjects aged 39-45 yr derived from a community cohort of 2,056 asymptomatic children originally studied in 1964. Participants included 102 cases with adult onset wheeze (since age 15) and 217 controls with no wheeze. Logistic regression analysis was used to determine independent risk factors for wheeze among all cases and three subgroups: doctor diagnosed asthma (n = 24), wheeze with chronic cough and phlegm (n = 31), and other wheeze (n = 47). The risk of adult onset wheeze among all cases increased with low socioeconomic status (relative risk [RR] 2.36), current smoking (RR 2.01), positive atopic status (RR 3.28), and positive family history of atopic disease (RR 5.49). Gender was not related to the risk of wheezing. The pattern of significant independent risk factors differed between the subgroups of cases. Socioeconomic status was associated with cough and phlegm and other wheeze. Smoking habit was only related to cough and phlegm. Atopy was associated with doctor diagnosed asthma and cough and phlegm. Family history of atopic disease was related to all subgroups, suggesting that despite apparent heterogeneity in diagnostic labeling, concurrent symptoms, and other risk factors, the different forms of adult onset wheeze may share a common allergic basis.
