Treating childhood asthma in Singapore: when West meets East.

Though Western medicines and ideas about asthma have become popular in many Asian nations, local beliefs about treatment prevail. The multiracial society of Singapore shows a variety of beliefs about causes of asthma attacks (for example, the balance of yin and yang) and types of treatment--herbal remedies, inhaled versus eaten medicines, the influence of Ramadan. Many of the cultural practices mentioned are probably preserved among south east Asian minorities residing in the United Kingdom. Eastern treatments typically take a holistic approach to asthma and do not ignore the psychosomatic component of the disorder.     

Use of oral corticosteroids in the community and the prevention of secondary osteoporosis: a cross sectional study.

OBJECTIVE--To determine the prevalence of continuous use of oral steroids in the general population, the conditions for which they are prescribed, and the extent to which patients taking oral steroids are taking treatment to prevent osteoporosis. DESIGN--A cross sectional study with a four year retrospective review of drug treatment. SETTING--Eight large general practices in central and southern Nottinghamshire. SUBJECTS--A population of 65,786 patients (52% women) registered with a general practitioner during 1995. RESULTS--303 patients (65% (197) women) aged 12-94 years were currently taking "continuous" (for at least three months) oral corticosteroid treatment. This figure represents 0.5% of the total population and 1.4% (245/17 114) of patients aged 55 years or more (1.7% (166/9601) of women). The usual steroid was prednisolone (97% (294/303)), the mean dose was 8.0 mg/day, and the median duration of oral steroid treatment determined in 149 patients was three years. The most common conditions for which continuous oral steroids were prescribed were rheumatoid arthritis (23% (70)), polymyalgia rheumatica (22% (66)), and asthma or chronic obstructive airways disease (19% (59)). Only 41 (14%) of the 303 patients taking oral steroids had received treatment for the prevention of osteoporosis over the past four years. Although 37 of the 41 patients were women, only 10% (18/181) of the women over 45 years taking continuous oral corticosteroids were currently taking hormone replacement therapy. CONCLUSIONS--If our figures are typical then they suggest that over 250,000 people in the United Kingdom are taking continuous oral steroids and that most of these are taking no prophylaxis against osteoporosis.     

Implications of prognostic pessimism in patients with chronic obstructive pulmonary disease (COPD) or asthma admitted to intensive care in the UK within the COPD and asthma outcome study (CAOS): multicentre observational cohort study

Objective To determine whether clinicians'' prognoses in patients with severe acute exacerbations of obstructive lung disease admitted to intensive care match observed outcomes in terms of survival.Design Prospective cohort study.Setting 92 intensive care units and three respiratory high dependency units in the United Kingdom.Participants 832 patients aged 45 years and older with breathlessness, respiratory failure, or change in mental status because of an exacerbation of COPD, asthma, or a combination of the two.Main outcome measures Outcome predicted by clinicians. Observed survival at 180 days. Results 517 patients (62%) survived to 180 days. Clinicians'' prognoses were pessimistic, with a mean predicted survival of 49% at 180 days. For the fifth of patients with the poorest prognosis according to the clinician, the predicted survival rate was 10% and the actual rate was 40%. Information from a database covering 74% of intensive care units in the UK suggested no material difference between units that participated and those that did not. Patients recruited were similar to those not recruited in the same units.Conclusions Because decisions on whether to admit patients with COPD or asthma to intensive care for intubation depend on clinicians'' prognoses, some patients who might otherwise survive are probably being denied admission because of unwarranted prognostic pessimism.     

Preliminary analysis of the care of injured patients in 33 British hospitals: first report of the United Kingdom major trauma outcome study.

OBJECTIVE--To measure the effectiveness of management of major trauma in the United Kingdom. DESIGN--Review of the care of all seriously injured patients seen over two years. SETTING--33 hospitals which receive patients who have sustained major trauma. SUBJECTS--14,648 injured patients admitted for more than three days, transferred or admitted into an intensive care bed, or dying from their injuries. MAIN OUTCOME MEASURE--Death or survival in hospital within three months of the injury. RESULTS--21% of seriously injured patients (1299) took longer than one hour to reach hospital. Time before arrival at hospital was not related to severity of injury. A senior house officer was in charge of initial hospital resuscitation in 57% (826/1445) of patients with an injury severity score > or = 16. More senior staff were commonly responsible for definitive operations, but only 46% (165/355) of patients judged to require early operation arrived in theatre within two hours. Mortality for 6111 patients sustaining blunt trauma and treated in the 14 busiest hospitals was significantly higher (actual 408, predicted 295.6, p < 0.001) than in a comparable North American dataset. Large differences in the 14 hospitals assessed could not be explained by variations in case load or facilities. In contrast, the outcome of the 4.1% (597) of patients with penetrating injuries was better than that of a comparable group in the United States. Analysis of the 415 penetrating injuries with complete data showed that 15 patients died (19.3 predicted; p = 0.04). CONCLUSIONS--The initial management of major trauma in the United Kingdom remains unsatisfactory. There are delays in providing experienced staff and timely operations. Mortality varies inexplicably between hospitals and, for blunt trauma, is generally higher than in the United States.     

Management of breast cancer in southeast England.

OBJECTIVE--To examine the extent to which management of invasive breast cancer reflected consensus guidelines in the Thames regions in 1990. DESIGN--Population based study of case notes. SETTING--Thames Cancer Registry. SUBJECTS--All women with breast cancer diagnosed in early 1990 (417 cases) resident in the four Thames regions. Hospital records were traced for 346 cases, of which 12 were ineligible because of misclassification in initial registration and were excluded from the analysis. 334 cases were analysed. MAIN OUTCOME MEASURES--Investigations and treatment in the six months after diagnosis, stage of disease. RESULTS--Of the 334 women identified, 86 were aged under 50. Three years after diagnosis, 74 were dead, seven (8%) aged under 50 and 67 (27%) aged 50 or over. Axillary surgery was used to stage cancer in only 155 cases (46%), although this is recommended in the guidelines. Only 79 (24%) case notes had any information recorded on stage. Stage could be determined reliably for only half of the sample. Treatment varied widely within the same age group and stage of disease. In particular, chemotherapy was not routinely given to patients under 50 with stage II disease. Only 17 records showed evidence that the patient was participating in a clinical trial. CONCLUSIONS--There was a lack of consensus on the management of breast cancer among clinicians in 1990. More patients should be included in clinical trials.     

Is childhood asthma being underdiagnosed and undertreated?

Thirty-four cases of asthma in children referred to outpatient clinics in Newcastle upon Tyne (16 cases) and London (18 cases) were reviewed. In both cities there was evidence of inappropriate diagnosis and treatment by general practitioners. One of the main factors seemed to be doctors'' reluctance to use the word "asthma," even when a history of episodic wheezing strongly suggested the diagnosis. Freer use of the word "asthma" might help parents to co-operate in managing asthmatic children and allow them to be better prepared to cope with severe asthmatic attacks if they occur.     

The effects of clinical practice guidelines on patient outcomes in primary care: a systematic review

OBJECTIVE: To assess the evidence for the effectiveness of clinical practice guidelines (CPGs) in improving patient outcomes in primary care. DATA SOURCES: A search of the MEDLINE, HEALTHPLAN, CINAHL and FAMLI databases was conducted to identify studies published between Jan. 1, 1980, and Dec. 31, 1995, concerning the use of guidelines in primary medical care. The keywords used in the search were "clinical guidelines," "primary care," "clinical care," "intervention," "randomized controlled trial" and "effectiveness." STUDY SELECTION: Studies of the use of CPGs were selected if they involved a randomized experimental or quasi-experimental method, concerned primary care, were related to clinical care and examined patient outcomes. Of 91 trials of CPGs identified through the search, 13 met the criteria for inclusion in the critical appraisal. DATA EXTRACTION: The following data were extracted, when possible, from the 13 trials: country and setting, number of physicians, number of patients (and the proportion followed to completion), length of follow-up, study method (including random assignment method), type of intervention, medical condition treated and effect on patient outcomes (including clinical and statistical significance, with confidence intervals). DATA SYNTHESIS: The most common conditions studied were hypertension (7 studies), asthma (2 studies) and cigarette smoking (2 studies). Four of the studies followed nationally developed guidelines, and 9 used locally developed guidelines. Six studies involved computerized or automated reminder systems, whereas the others relied on small-group workshops and education sessions. Only 5 of the 13 trials (38%) produced statistically significant results. CONCLUSION: There is very little evidence that the use of CPGs improves patient outcomes in primary medical care, but most studies published to date have used older guidelines and methods, which may have been insensitive to small changes in outcomes. Research is needed to determine whether the newer, evidence-based CPGs have an effect on patient outcomes.     

Guidelines for the emergency management of asthma in adults. CAEP/CTS Asthma Advisory Committee. Canadian Association of Emergency Physicians and the Canadian Thoracic Society.

OBJECTIVE: To develop a set of comprehensive, standardized evidence-based guidelines for the assessment and treatment of acute asthma in adults in the emergency setting. OPTIONS: The use of medications was evaluated by class, dose, route, onset of action and optimal mode of delivery. The use of objective measurements and clinical features to assess response to therapy were evaluated in relation to the decision to admit or discharge the patient or arrange for follow-up care. OUTCOMES: Control of symptoms and disease reflected in hospital admission rates, frequency of treatment failures following discharge, resolution of symptoms and improvement of spirometric test results. EVIDENCE: Previous guidelines, articles retrieved through a search of MEDLINE, emergency medical abstracts and information from members of the expert panel were reviewed by members of the Canadian Association of Emergency Physicians (CAEP) and the Canadian Thoracic Society. Where evidence was not available, consensus was reached by the expert panel. The resulting guidelines were reviewed by members of the parent organizations. VALUES: The evidence-based methods and values of the Canadian Task Force on the Periodic Health Examination were used. BENEFITS, HARMS AND COSTS: As many as 80% of the approximate 400 deaths from asthma each year in Canada are felt to be preventable. The use of guidelines, aggressive emergency management and consistent use of available options at discharge are expected to decrease the rates of unnecessary hospital admissions and return visits to emergency departments because of treatment failures. Substantial decreases in costs are expected from the use of less expensive drugs, or drug delivery systems, fewer hospital admissions and earlier return to full activity after discharge. RECOMMENDATIONS: Beta2-agonists are the first-line therapy for the management of acute asthma in the emergency department (grade A recommendation). Bronchodilators should be administered by the inhaled route and titrated using objective and clinical measures of airflow limitation (grade A). Metered-dose inhalers are preferred to wet nebulizers, and a chamber (spacer device) is recommended for severe asthma (grade A). Anticholinergic therapy should be added to beta 2 agonist therapy in severe and life-threatening cases and may be considered in cases of mild to moderate asthma (grade A). Aminophylline is not recommended for use in the first 4 hours of therapy (grade A). Ketamine and succinylcholine are recommended for rapid sequence intubation in life-threatening cases (grade B). Adrenaline (administered subcutaneously or intravenously), salbutamol (administered intravenously) and anesthetics (inhaled) are recommended as alternatives to conventional therapy in unresponsive life-threatening cases (grade B). Severity of airflow limitation should be determined according to the forced expiratory volume at 1 second or the peak expiratory flow rate, or both, before and after treatment and at discharge (grade A). Consideration for discharge should be based on both spirometric test results and assessment of clinical risk factors for relapse (grade A). All patients should be considered candidates for systemic corticosteroid therapy at discharge (grade A). Those requiring corticosteroid therapy should be given 30 to 60 mg of prednisone orally (or equivalent) per day for 7 to 14 days; no tapering is required (grade A). Inhaled corticosteroids are an integral component of therapy and should be prescribed for all patients receiving oral corticosteroid therapy at discharge (grade A). Patients should be given a discharge treatment plan and clear instructions for follow-up care (grade C). VALIDATION: The guidelines share the same principles of those from the British Thoracic Society and the National Institutes of Health. Two specific validation initiatives have been undertaken: (a) several Canadian centres have been involved in the collection of comprehensive administrative data to assess compliance and outcome measures and (b) a survey of Canadian emergency physicians conducted to gather baseline informaton of treatment patterns, was conducted before development of the guidelines and will be repeated to re-evaluate emergency management of asthma.     

Incidence of AIDS and excess of mortality associated with HIV in haemophiliacs in the United Kingdom: report on behalf of the directors of haemophilia centres in the United Kingdom.

OBJECTIVE--To estimate the cumulative incidence of AIDS by time since seroconversion in haemophiliacs positive for HIV and to examine the evidence for excess mortality associated with HIV in those who had not yet been diagnosed as having AIDS. DESIGN--Analysis of data from ongoing national surveys. SETTING--Haemophilia centres in the United Kingdom. PATIENTS--A total of 1201 men with haemophilia who had lived in the United Kingdom during 1980-7 and were positive for HIV. INTERVENTION--None. END POINTS--Diagnosis of AIDS; death in those not diagnosed as having AIDS. MEASUREMENTS AND MAIN RESULTS--Estimation of cumulative incidence of AIDS and number of excess deaths in seropositive patients not diagnosed with AIDS. Median follow up after seroconversion was 5 years 2 months. Eight five patients developed AIDS. Cumulative incidence of AIDS five years after seroconversion was 4% among patients aged less than 25 at first test positive for HIV, 6% among those aged 25-44, and 19% among those aged greater than or equal to 45. There was little evidence that type or severity of haemophilia or type of factor VIII or IX that had caused HIV infection affected the rate of progression to AIDS. Mortality was increased among those who had not been diagnosed as having AIDS, especially among those with "AIDS related complex." Thirteen deaths were observed among 36 patients diagnosed as having AIDS related complex against 0.65 expected, and 34 deaths in 1080 other patients against 22.77 expected; both calculations were based on mortality rates observed in haemophiliacs in the United Kingdom in the late 1970s. CONCLUSIONS--Rate of progression to AIDS depended strongly on age. There is a substantial burden of fatal disease among patients positive for HIV who have not been formally diagnosed as having AIDS.     

Death from asthma in two regions of England

The British Thoracic Association has conducted a confidential inquiry into death from asthma of adults aged 15 to 64 years resident in the West Midland and Mersey regions in 1979. Information concerning the patients, their asthma, and death was obtained by questionnaire, interview with the general medical practitioner and a relative, and from patient records. A panel of three physicians, helped by a pathologist, identified 90 patients as dying of asthma and assessed management and treatment in the last year, last month of life, and the fatal attack. They were generally chronic asthmatics, but unstable, most having suffered severe attacks previously. Corticosteroids and bronchodilator drugs were in general underprescribed or not given in sufficiently large doses. Inhaled corticosteroids and cromoglycate had frequently not been tried. The patient''s co-operation with the management of the asthma was satisfactory for only 42 of the 90 patients. For 71 of the patients the fatal attack lasted under 24 hours; of the 77 who died at home or at work, 50 did not receive any medical attention in the fatal attack. Failure to recognise the severity of the asthma by patients, relatives, and doctor often caused delay in starting appropriate treatment. The interaction of several of these adverse factors often contributed to the patient''s death. The panel considered that there were potentially preventable factors contributory to the death of 77 (86%) of the 90 patients. Within the limits of retrospective judgment the panel considered that the routine management of the asthma was often unsatisfactory as patients known to suffer severe acute attacks were often not adequately supervised or instructed in the management and treatment of their asthma. From this retrospective inquiry we concluded that closer overall supervision, including careful attention to patient education, earlier and more intensive treatment, and pre-arranged immediate admission to hospital for asthma emergencies is desirable.     

Sporadic Creutzfeldt-Jakob disease in the United Kingdom: analysis of epidemiological surveillance data for 1970-96.

OBJECTIVE: To identify changes in the occurrence of Creutzfeldt-Jakob disease that might be related to the epidemic of bovine spongiform encephalopathy. DESIGN: Epidemiological surveillance of the United Kingdom population for Creutzfeldt-Jakob disease based on (a) referral of suspected cases by neurologists, neuropathologists, and neurophysiologists and (b) death certificates. SETTING: England and Wales during 1970-84, and whole of the United Kingdom during 1985-96. SUBJECTS: All 662 patients identified as sporadic cases of Creutzfeldt-Jakob disease. MAIN OUTCOME MEASURES: Age distribution of patients, age specific time trends of disease, occupational exposure to cattle, potential exposure to causative agent of bovine spongiform encephalopathy. RESULTS: During 1970-96 there was an increase in the number of sporadic cases of Creutzfeldt-Jakob disease recorded yearly in England and Wales. The greatest increase was among people aged over 70. There was a statistically significant excess of cases among dairy farm workers and their spouses and among people at increased risk of contact with live cattle infected with bovine spongiform encephalopathy. During 1994-6 there were six deaths from sporadic Creutzfeldt-Jakob disease in the United Kingdom in patients aged under 30. CONCLUSIONS: The increase in the incidence of sporadic Creutzfeldt-Jakob disease and the high incidence in dairy farmers in the United Kingdom may be unrelated to bovine spongiform encephalopathy. The most striking change in the pattern of Creutzfeldt-Jakob disease in the United Kingdom after the epidemic of bovine spongiform encephalopathy is provided by the incidence in a group of exceptionally young patients with a consistent and unusual neuropathological profile. The outcome of mouse transmission studies and the future incidence of the disease in the United Kingdom and elsewhere, will be important in judging whether the agent causing bovine spongiform encephalopathy has infected humans.     

The abortion issue

The capsular type of 160 strains of pneumococci isolated from blood or cerebrospinal fluid of patients in Alberta and Ontario between June 1978 and August 1980 was determined. Of the 83 known serotypes 36 were represented, and the type distribution was similar to that reported from the United Kingdom and the United States. Although only 111 (69.3%) of the strains belonged to the serotypes represented in the licensed pneumococcal vaccine, if related types within the same serogroup are also included 132 (82.5%) of the strains belonged to the types or groups represented in the vaccine, However, because the vaccine is not recommended for persons aged less than 2 years, from whom 30 strains were isolated, and because 28 strains from those 2 years of age and older were of nonvaccine types or groups, one can presume that 58 (36.3%) of the 160 bacteremic and meningitic infections would not have been prevented by prior vaccination, even if the vaccine were completely effective.     

Serevent nationwide surveillance study: comparison of salmeterol with salbutamol in asthmatic patients who require regular bronchodilator treatment.

OBJECTIVE--To compare safety of salmeterol and salbutamol in treating asthma. DESIGN--Double blind, randomised clinical trial in parallel groups over 16 weeks. SETTING--General practices throughout the United Kingdom. SUBJECTS--25,180 patients with asthma considered to require regular treatment with bronchodilators who were recruited by their general practitioner (n = 3516). INTERVENTIONS--Salmeterol (Serevent) (50 micrograms twice daily) or salbutamol (200 micrograms four times a day) randomised in the ratio of two patients taking salmeterol to one taking salbutamol. All other drugs including prophylaxis against asthma were continued throughout the study. MAIN OUTCOME MEASURES--All serious events and reasons for withdrawals (medical and non-medical) whether or not they were considered to be related to the drugs. RESULTS--Fewer medical withdrawals due to asthma occurred in patients taking salmeterol than in those taking salbutamol (2.91% v 3.79%; chi 2 = 13.6, p = 0.0002). Mortality and admissions to hospital were as expected. There was a small but non-significant excess mortality in the group taking salmeterol and a significant excess of asthma events including deaths in patients with severe asthma on entry. Use of more than two canisters of bronchodilator a month was particularly associated with the occurrence of an adverse asthma event. CONCLUSIONS--Treatment over 16 weeks with either salmeterol or salbutamol was not associated with an incidence of deaths related to asthma in excess of that predicted. Overall control of asthma was better in patients allocated to salmeterol. Serious adverse events occurred in patients most at risk on entry and were probably due to the disease rather than treatment.     

Role of the general practitioner in managing patients with myocardial infarction: impact of thrombolytic treatment. Report of a British Heart Foundation Working Group.

Thrombolytic treatment, combined with aspirin, has been shown to reduce mortality by half in patients in hospital with suspected acute myocardial infarction if it is given early after the onset of symptoms. This fact adds to the importance of prompt and skillful intervention. At present in the United Kingdom the median time for receiving suitable management for this condition is about four to six hours. With better organisation this delay could, in most areas, be reduced to two or three hours. A major change in the care of patients with myocardial infarction is needed in which the general practitioner should have a crucial role. Health authorities, hospital physicians, general practitioners, and the ambulance services must coordinate their efforts if the potential reduction in mortality is to be realised. The district medical officer should consult colleagues and draw up guidelines for organising the care of patients who have had heart attacks. The management of patients who have had heart attacks in the community and in hospital should be continually audited. There are dangers inherent in the use of thrombolytic treatment, particularly when conditions other than myocardial infarction are treated in error. This treatment should be given only when the diagnosis is highly probable and when close observation of the patient can be ensured during the ensuing hours. Thrombolytic treatment should not, therefore, be given out of hospital except when trained, equipped personnel are in attendance. Treatment can be given in any hospital (including community hospitals) provided there are adequate diagnostic facilities and suitably experienced nursing staff.     

Postmarketing surveillance: practical experience with ketotifen.

In a postmarketing surveillance of ketotifen (Zaditen), an oral preparation for the prophylaxis of bronchial asthma, 8291 patients completed records every three months for one year. The objectives were to record adverse events and efficacy and to communicate appropriate information to participating doctors and regulatory authorities. The patients recruited appeared to represent a typical cross section of patients with asthma in the United Kingdom. By subjective assessment 70% of patients found the medication efficacious. There were no unexpected or unacceptable side effects and those found were similar to those reported in clinical trials of ketotifen. Though this exercise showed that the pharmaceutical industry, regulatory authorities, and prescribing doctors were able to collaborate, the major outcome of the survey was already known. It remains to be seen whether this type of survey is of value in the continuing search for control and safety in prescribing.     

75 deaths in asthmatics prescribed home nebulisers.

The circumstances surrounding the deaths of 75 asthmatic patients who had been prescribed a domiciliary nebuliser driven by an air compressor pump for administration of high dose beta sympathomimetic drugs were investigated as part of the New Zealand national asthma mortality study. Death was judged unavoidable in 19 patients who seemed to have precipitous attacks despite apparently good long term management. Delays in seeking medical help because of overreliance on beta agonist delivered by nebuliser were evident in 12 cases and possible in a further 11, but these represented only 8% of the 271 verified deaths from asthma in New Zealanders aged under 70 during the period. Evidence for direct toxicity of high dose beta agonist was not found. Nevertheless, the absence of serum potassium and theophylline concentrations and of electrocardiographic monitoring in the period immediately preceding death precluded firm conclusions whether arrhythmias might have occurred due to these factors rather than to hypoxia alone. In most patients prescribed domiciliary nebulisers death was associated with deficiencies in long term and short term care similar to those seen in patients without nebulisers. Discretion in prescribing home nebulisers, greater use of other appropriate drugs, including adequate corticosteroids, and careful supervision and instruction of patients taking beta agonist by nebuliser should help to reduce the mortality from asthma.     

Controlled investigation of deaths from asthma in hospitals in the North East Thames region.

One hundred and thirty deaths definitely or potentially due to asthma occurring in hospitals in the North East Thames region over one year were identified from death certificates and Hospital Activity Analysis records. Thirty five of these deaths were considered after independent assessment to have been directly due to asthma. Control patients who left hospital alive after acute asthma attacks were selected and matched with cases for sex, age, and hospital. Management was compared in the two groups. Inadequate monitoring, including failure to monitor arterial blood gas values, and inadequate use of nebulised beta agonists occurred significantly more often in fatal cases. Use of sedation, inadequate treatment with steroids, exposure to potentially toxic doses of aminophylline, and inadequate clinical assessment were more common in cases than controls, but not significantly so. Failure to institute artificial ventilation contributed to seven deaths. Assessors considered important defects in management to have occurred in 83% (29/35) of the cases and 40% (14/35) of the controls. Nevertheless, most of the hospital deaths (19/35) were considered not to have been preventable. Eight other deaths in the region were attributed to the complications of asthma or its treatment. Three of these were associated with gastrointestinal bleeding and one with perforation of a duodenal ulcer. Before considering policies aimed at speeding admission to hospital of patients with acute attacks of asthma it is crucial that the general standard of hospital care offered to all patients with asthma should be improved.     

Asthma mortality in Birmingham 1975-7: 53 deaths.

Out of 83 patients studied 72 were certified as dying from asthma, and 11 aged under 45 as dying from chronic bronchitis and pneumonia. Fifty-three deaths were thought to be due to asthma. There were avoidable factors associated with several of these deaths from asthma. Recent discharge from hospital (16%), non-availability of aerosol bronchodilators (45%), underuse of corticosteroids (66%), and lack of objective measurements of airflow obstruction (100%) were found in deaths outside hospital. Inadequate initial assessment including baseline spirometry and blood gases (50%), significant underusage of corticosteroids (93%) and intravenous and nebulised bronchodilators (100%), and failure to monitor treatment objectively (100%) were found in deaths in hospital. "False-positive" and "false-negative" certifications of asthma were studied, and the findings suggest that these may lead to appreciable inaccuracy in the reporting of deaths from asthma.     

BACUP--the first two years: evaluation of a national cancer information service.

The cancer information service of the British Association of Cancer United Patients (BACUP) was launched in October 1985 as a national service to patients and their relatives, the public, and health professionals. Information is provided by telephone and letter by seven nurses trained in oncology. In the first two years over 30,000 inquiries were received: 23,527 (80%) were from women; 9445 (32%) were from cancer patients 11,574 (39%) from relatives of patients, and 2869 (10%) from health professionals. Inquiries came from all over the United Kingdom and from all sections of society but users were predominantly middle class, aged between 30 and 49, and living in south east England. Information about specific cancer sites, treatment, and how to cope was most commonly sought. Nearly a third of all inquiries were related to breast cancer. Though the service is used more by particular groups focusing on particular diseases, clearly there is a need for a cancer information service in the UK.
