A randomised trial of home energy efficiency improvement in the homes of elderly COPD patients.

A randomised trial of 178 patients in Aberdeen, UK with a previous hospital admission for chronic obstructive pulmonary disease (COPD) was carried out in order to determine whether improving home energy efficiency improves health-related quality of life in COPD patients. 118 patients were randomised and 60 agreed to monitoring only. Energy efficiency upgrading was carried out in 42% of homes randomised to intervention. Independent energy efficiency action was taken by 15% of control participants and 18% in the monitoring group. The main outcome measures were respiratory and general health status, home energy efficiency and hospital admissions. Intention-to-treat analysis found no difference in outcomes between the two groups. In 45 patients, who had energy efficiency action independent of original randomisation, there were significant improvements in respiratory symptom scores (adjusted mean 9.0, 95% CI 2.5-15.5), decreases in estimated annual fuel costs (- pound65.3, 95% CI - pound31.9- - pound98.7) and improved home energy efficiency rating (1.1, 95% CI 0-1.4). COPD patients are unlikely to take up home energy efficiency upgrading, if offered. Secondary "pragmatic" analysis suggests that those who do take action may achieve clinically significant improvement in respiratory health, which is not associated with an increase in indoor warmth.

Patient-reported adverse events under asthma therapy: a community pharmacy-based survey.

The characteristics of patients who report adverse events (AEs) attributed to asthma therapy have been little investigated. Asthma patients aged 18-50 years were surveyed in pharmacies. Patients completed a questionnaire linked to computerized records of dispensed medications. Patients reported all AEs that they attributed to asthma therapy. The correlates of reporting 2+ AEs were identified. Almost 59% of the 1,351 patients (mean age: 37, 56% females) attributed AEs to asthma therapy, and 35% at least two. Most common AEs included tiredness (21.8%) and palpitations (21.1%). Poor asthma control and perception of asthma as a handicap were the major correlates of reporting 2+ AEs (odds ratio (OR)=2.5, 95% confidence interval (CI)=[1.7-3.7] and OR=1.9, 95% CI=[1.4-2.5]). Other significant correlates included age >30 years, female gender, and receiving psychotropic therapy. Inadequate control may partly account for AEs attributed by patients to asthma therapy. Improving patients' education may help to improve acceptability of asthma therapy.

Increases in asthma hospital admissions associated with the end of the summer vacation for school-age children with asthma in two cities from England and Scotland.

In school-age asthmatics, an increase in hospitalizations has been reported in early autumn. This increase in admissions is conjectured to be associated with the return back to school. In the UK schools in England complete their summer vacations 2 weeks later than in Scotland and so there should be a lag between the two countries in the increase in asthma episode. Daily hospital asthma admission data from Aberdeen (in Scotland) and Doncaster (in England) for the period July 23rd to October 8th for years 1999-2004 were included in the analysis. There are peaks in hospitalization after the return back to school for both Aberdeen and Doncaster with the peak for Doncaster appearing 2 weeks after Aberdeen. This study has demonstrated peaks in admissions in school-age children around the return back to school in two cities where different school return dates were reflected in a 2-week lag effect. These data therefore provide strong evidence that peaks in admissions are associated with the end of the summer holidays.

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.

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.

Parental education and guided self-management of asthma and wheezing in the pre-school child: a randomised controlled trial.

BACKGROUND: The effects on morbidity were examined of providing an educational intervention and a written guided self-management plan to the parents of pre-school children following a recent attendance at hospital for asthma or wheeze. METHODS: A prospective, randomised, partially blinded, controlled trial was designed at two secondary care centres. Over a 13 month period 200 children aged 18 months to 5 years at the time of admission to a children's ward or attendance at an accident and emergency department or children's (emergency) assessment unit (A&E/CAU) with a primary diagnosis of acute severe asthma or wheezing were recruited. 101 children were randomised into the control group and received usual care and 99 were assigned to the intervention group and received: (1) a pre-school asthma booklet; (2) a written guided self-management plan; and (3) two 20 minute structured educational sessions between a specialist respiratory nurse and the parent(s) and child. Subjects were assessed at 3, 6, and 12 months. The main outcomes were GP consultation rates, hospital re-admissions, and attendances at A&E/CAU. Secondary outcomes included disability score, caregivers' quality of life, and parental knowledge of asthma. RESULTS: There were no statistically significant differences between the two groups during the 12 month follow up period for any of the main or secondary outcome measures. CONCLUSIONS: These results do not support the hypothesis that the introduction of an educational package and a written guided self-management plan to the parents of pre-school children with asthma who had recently attended hospital for troublesome asthma or wheeze reduces morbidity over the subsequent 12 months.

Cost effectiveness of computer tailored and non-tailored smoking cessation letters in general practice: randomised controlled trial.

OBJECTIVES: To develop and evaluate, in a primary care setting, a computerised system for generating tailored letters about smoking cessation. DESIGN: Randomised controlled trial. SETTING: Six general practices in Aberdeen, Scotland. PARTICIPANTS: 2553 smokers aged 17 to 65. INTERVENTIONS: All participants received a questionnaire asking about their smoking. Participants subsequently received either a computer tailored or a non-tailored, standard letter on smoking cessation, or no letter. MAIN OUTCOME MEASURES: Prevalence of validated abstinence at six months; change in intention to stop smoking in the next six months. RESULTS: The validated cessation rate at six months was 3.5% (30/857) (95% confidence interval 2.3% to 4.7%) for the tailored letter group, 4.4% (37/846) (3.0% to 5.8%) for the non-tailored letter group, and 2.6% (22/850) (1.5% to 3.7%) for the control (no letter) group. After adjustment for significant covariates, the cessation rate was 66% greater (-4% to 186%; P=0.07) in the non-tailored letter group than that in the no letter group. Among participants who smoked <20 cigarettes per day, the cessation rate in the non-tailored letter group was 87% greater (0% to 246%; P=0.05) than that in the no letter group. Among heavy smokers who did not quit, a 76% higher rate of positive shift in "stage of change" (intention to quit within a particular period of time) was seen compared with those who received no letter (11% to 180%; P=0.02). The increase in cost for each additional quitter in the non-tailored letter group compared with the no letter group was pound 89. CONCLUSIONS: In a large general practice, a brief non-tailored letter effectively increased cessation rates among smokers. A tailored letter was not effective in increasing cessation rates but promoted shift in movement towards cessation ("stage of change") in heavy smokers. As a pragmatic tool to encourage cessation of smoking, a mass mailing of non-tailored letters from general practices is more cost effective than computer tailored letters or no letters.

Parents' quality of life and respiratory symptoms in young children with mild wheeze. EASE Study Group.

The Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ), measures the impact of child asthma symptoms on family activity (CGAct) and parental anxiety (CGEmot). It has not been validated for families of children <7 yrs, with wheezing illness. This study assessed the sensitivity of the PACQLQ to symptom change in 62 preschool children with wheezing illness. The median age of children was 3 yrs (range 0.8-6 yrs). At entry and 3-month follow-up, parents recorded child respiratory symptoms in a 1-month diary and completed the PACQLQ. On average, children in the study had 7 symptomatic days per month. On entry, mothers < or = 30 yrs had worse scores than those > 30 (p < 0.02), and mothers in less affluent socioeconomic groups had worse scores than those in higher groups (p = 0.05). Change in symptom scores and symptom free days between entry and follow-up was associated with change in PACQLQ scores (r = 0.54-0.57, p <0.001). Thirty-three parents had absolute change in PACQLQ of <0.5 over three months (which has been previously defined as not being clinically significant). Compared to parents with higher PACQLQ change, parents with PACQLQ scores <0.5, did not differ in frequency of child symptoms or in social-demographic factors, but had better quality of life scores on entry to the study (p<0.01). It is concluded that the Paediatric Asthma Caregiver's Quality of Life Questionnaire is sensitive to group measures of child symptom change over 3 months, among preschool children, and this supports its use as an outcome measure in clinical trials. The absolute impact of child symptoms on parent quality of life varies among parents.

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.

Early asthma prophylaxis, natural history, skeletal development and economy (EASE): a pilot randomised controlled trial.

OBJECTIVES: (1) To establish recruitment rates of newly presenting asthmatic children. (2) To establish acceptability of study protocols. (3) To pilot age-specific quality of life (QoL) assessment. (4) To assess short-term (6 months) outcomes of inhaled corticosteroids (ICS) treatment. (5) To refine sample size calculations for a definitive study. DESIGN: A randomised pragmatic longitudinal trial design was used, with no blinding or placebo, to examine early ICS introduction similar to its use in practice. Subjects were assessed at entry, 3 and 6 months. SETTING: Subjects were recruited from six general practices. Children under 6 years were assessed at the Craig Research and Investigation Unit, Royal Aberdeen Children's Hospital, or their family home, and subjects 6 years and over were assessed at their general practice. SUBJECTS: Children (aged 6 months-16 years) with symptoms suggestive of asthma/wheeze that had commenced no longer than 12 months before were identified retrospectively and prospectively from general practices. Subjects were also required to be naïve to prophylactic therapy with no other lung disease/concomitant illness. INTERVENTIONS: Subjects were randomised to ss2-agonist (ss2-only group) or ss2-agonist and ICS (ICS group) for 6 months. Physicians could later prescribe ICS in controls if needed. MAIN OUTCOME MEASURES: (1) Pulmonary function. (2) Asthma symptom diary. (3) Symptomatic health status questionnaire. (4) Caregiver's and child's QoL. (5) Growth. (6) Bone mass. (7) Bone turnover. (8) Economic issues. RESULTS: Of over 15,000 children yielded from general practice records, 11% had symptoms suggestive of asthma/wheeze, and two-thirds of these already used ICS. Of the remaining, 141 subjects met the criterion of early asthma, and 86 were randomised. Two-thirds of those randomised were < 6 years old, the males:females ratio was 2:1, and 67% had a family history of atopy. RESULTS - PHYSIOLOGICAL DEVELOPMENT: Pulmonary function did not significantly improve in the older children. Although tidal breathing measures in the pre-school children were significantly higher at 6 months in the ss2-only group, there was great variability. Incidence of wheeze and night-time cough reduced equally in both groups. Reduction of night-time symptom score and reliever use, and increase in symptom-free days were only significant in the ss2-only group. No significant differences were found in growth and bone mass between the two groups, but bone metabolism was significantly reduced at 6 months in the ICS group. RESULTS - PSYCHOLOGICAL DEVELOPMENT: The caregiver's QoL questionnaire was sensitive to child symptom changes over 3 months, but absolute impact of child symptoms on their QoL varied, whereas the child-centred questionnaire was not sensitive to change. RESULTS - ECONOMICS: There were no significant differences in medical consultation costs between the groups, but, as expected, prescription costs in the ICS group were higher over 6 months. Combined healthcare costs were significantly higher for patients assigned to ICS, but there were no significant differences in any effectiveness measures between the groups. CONCLUSIONS: Most (96%) of the proposed sample was recruited, and the low drop-out rate (8%) demonstrated acceptability of the study protocol. Most children first presenting with symptoms suggestive of asthma were < 6 years old and represented a group biased towards mild to moderate asthma, or virally induced wheeze. The caregiver's QoL questionnaire was found to better reflect a child's symptom changes than a child-centred instrument. In the short term, no adverse effects were seen on growth, but ICS treatment significantly reduced bone metabolism. Most of the young children with asthma/wheeze improved over time with ss2-agonist treatment alone, and clinical benefits of early ICS intervention amongst these children were not detected; however, there was inadequate power in this pilot study to establish this.

Attitudes to fertility issues among adults with cystic fibrosis in Scotland. The Collaborative Group of Scottish Adult CF Centres.

BACKGROUND: With increasing life expectancy, issues of fertility and pregnancy are pertinent to patients with cystic fibrosis. For this reason, the four Scottish Cystic Fibrosis centres asked men and women with cystic fibrosis about their attitudes to fertility and to information given to them by health professionals. METHODS: A postal questionnaire was sent to 116 men and 79 women aged 16 years and over attending four Scottish Cystic Fibrosis clinics. RESULTS: There was a 70% response rate (82 men, 54 women). All but two men knew that they were likely to be infertile. 37% of respondents lived with a partner; 14 women (26%) and five men (6%) had children. For 85% of men and 72% of women having children was important now or would be in the next 10 years. 43% of men and 26% of women had never had any discussion on fertility issues with cystic fibrosis health professionals. 56% of men thought that first discussion with a health professional about infertility should be before the age of 16 years; 12% remembered having a first discussion at that age. Learning of their infertility was associated with strong negative emotions for most men. Women were more likely than men to have initiated first discussion (17 (32%) versus eight (10%); p<0.01). Twenty five men (31%) and 32 women (59%) were currently using contraception. Ten men (12%) and 15 women (28%) had discussed contraception at the Cystic Fibrosis clinic (p = 0.01). CONCLUSIONS: Parenting and fertility issues are important for men and women with cystic fibrosis but many patients do not find out what they want to know from discussion with health professionals. Patients want discussion to begin in early adolescence. Men in particular are likely to be reluctant to introduce these issues; health professionals should be aware of the need actively to initiate discussion.

Symptoms, quality of life, and health service contact among young adults with mild asthma.

This report assesses Quality of Life (QoL) and its relationship to current symptoms and prospective medical contact among 396 adult patients with asthma. Patients were 16 to 52 yr of age and in the care of family physicians in the northeast of Scotland. All patients had been prescribed asthma medication within the previous 3 mo. Mean %pred FEV(1) was 87.4, mean %pred PEF was 85.1; 41% reported respiratory symptoms every week in the month before interview. Patients completed the SF-36, SF-12, and St. George's Respiratory Questionnaire (SGRQ) scales. Although mean scores on the SF-36 and SF-12 were close to population norms for patients without chronic illness, the presence of any respiratory symptoms in the month before interview was related to significantly lower QoL scores on the SF-36 scales of Physical Functioning, Energy, Mental Health, Pain, and Health Perception: the SF-12 Physical Functioning scale, and the SGRQ Symptoms, Impact and Activities scales. Physician contact for asthma in the 12 mo after interview was significantly related to SF-36, SF-12, and SGRQ scores at time of interview; however, when adjusted for symptoms at time of interview, only the SGRQ scales remained significant predictors of prospective physician contact. We conclude that respiratory symptoms have significant impact on QoL among patients with mild asthma, measured by generic and respiratory QoL scales, but that a specific respiratory scale is better able to discriminate patients who will seek physician care for asthma.

Requests for repeat medication prescriptions and frequency of acute episodes in asthma patients.

This study was conducted to determine if suboptimal use of inhaled steroid and over-reliance on bronchodilator medication to control asthma symptoms is associated with higher risk of acute asthma episodes. Details of repeat prescriptions for medication and use of health services over 12 months were collected for 754 adult outpatients with asthma; all were prescribed inhaled corticosteroid. Patients who requested less than five prescriptions per year were considered suboptimal users. Patients who requested seven or more bronchodilator prescriptions and less than five inhaled steroid prescriptions had significantly more family physician consultations for asthma episodes (p < 0.05), more hospital admissions (p < 0.05), and more disturbed nights in the week before hospital or family physician review (p < 0.05). Some patients with more severe asthma put themselves at risk by relying on bronchodilator medication rather than regular inhaled steroid for asthma control. Among patients who were low bronchodilator users, those who requested few inhaled steroid prescriptions were younger and more anxious but did not have an increased risk of acute asthma episodes.

Adult asthma review in general practice: nurses' perception of their role.

BACKGROUND: Asthma clinics have become widespread in general practice with nurses now playing an important role in asthma review. However, little is known about training of nurses carrying out reviews and how this affects the nurse role in patient management. OBJECTIVES: We aimed to discover the level of asthma training of practice nurses carrying out review of adult asthma patients in one Health Authority and to see if this has any effect on their perception of their role. METHOD: All 187 practice nurses in Grampian were sent a postal questionnaire investigating how asthma review is organized in general practice, their role in review and the asthma training they had received. Personal interviews were carried out with 17 nurses, exploring in more depth the topics covered in the questionnaire. RESULTS: A total of 167 nurses from 92% of the practices in Grampian responded, of whom 61% carried out asthma reviews. Among nurses carrying out reviews 71% did so on their own. 49% of nurses had or were training for advanced asthma qualification. Nurses without an asthma qualification were significantly more likely to feel that their training was not sufficient for their asthma related tasks (54% versus 11%, P = 0.0002). Nurses without advanced asthma qualifications were less likely to provide or review a self-management plan (29% versus 49%, P = 0.01), to review patient PEF recording (38% versus 65%, P < 0.01), to discuss patient worries (75% versus 94%, P < 0.05) or to make the initial diagnosis of asthma (24% versus 76%, P < 0.005). Nurses were unlikely to view their role as fully responsible unless they had an asthma qualification (13% versus 49%, P < 0.001). CONCLUSION: Nurses without advanced asthma qualifications do not feel fully confident in responsibility for patient management. Nurses without training are more likely to only carry out routine monitoring at reviews while nurses with asthma training are more likely to actively develop patient self-management skills. This suggests that nurses should be supported to obtain asthma qualifications if they are to give the best possible care to asthma patients.

How do patients' views about medication affect their self-management in asthma?

Successful management of asthma increasingly depends on decisions by patients about when and how to use inhalers and tablets prescribed for their asthma control. Patients with negative attitudes to asthma medication may not be willing to follow their management plan's advice to increase medication when their symptoms worsen. Patients do not always believe their doctors' reassurance about side effects. Although patient dislike of steroid medication is sometimes believed to be the main influence on reluctance to take medication, studies suggest that patients dislike taking any medication regularly. Evidence shows that patients are no more likely to use a combined inhaler regularly than separate steroid and relief inhalers. A proportion of patients with difficult to control asthma follow a chaotic self-management style. Attitudes among these patients may reflect personal styles, and be difficult to change. Among the majority of patients studies now show that patient self-management, and outcomes for patients can be improved by structured behavioural interventions. For most patients attitudes to medication will follow control of symptoms. The experience of successful control by medication, in the ways that patients think are important, are most likely to influence patients in positive attitudes to medication.

Integrated care for asthma: matching care to the patient.

The purpose of the present study was to investigate whether criteria associated with assignment of asthma patients between general practice (GP) care alone, integrated care (shared between GP care and hospital clinic) or conventional specialist review could be identified, and whether outcomes for these patients differed over the next 12 months. Seven hundred and sixty four patients with a diagnosis of asthma and previously assigned to either integrated care or clinic care were reviewed after 1 year and reassigned. These patients were then followed for another 12 months and clinical data were collected over this time. After 12 months in clinic care or integrated care, assignment to integrated care was predicted by previous participation in integrated care (OR 2.94), patient preference for integrated care (OR 3.7), no admission (OR 1.56), fewer steroid courses during the previous year (OR 0.88) and nonattendance at review (OR 0.43) in the previous 12 months. Patient discharge to GP care was predicted by higher level of forced expiratory volume in one second (FEV1) (OR 1.49), lower number of GP consultations for troublesome asthma (OR 0.78), and nonattendance for review in the preceding year (OR 2.15). In the following 12 months, the three groups of patients differed significantly in hospital admissions (Discharged = 0.008; Integrated = 0.12; Clinic = 0.31), bronchodilators prescribed (Discharged = 8.5; Integrated = 10.2; Clinic = 13.9), GP consultations (Discharged = 1.3; Integrated = 3.0; Clinic = 4.1) and oral steroid courses (Discharged = 0.62; Integrated = 1.7; Clinic = 2.4). Patients assigned to integrated care, clinic care or discharged to general practice care form three distinct patient populations differing retrospectively and prospectively in morbidity and admission risk. In particular, patients assigned to integrated care fall midway in risk and morbidity between those discharged or those retained in clinic care. These results suggest that integrated care provides general practitioners with a system of management for asthma patients, for whom they do not wish frequent specialist review but who they do not believe can safely be discharged to general practice care only.

Factors influencing mothers' decisions to consult a general practitioner about their children's illnesses.

BACKGROUND: In the management of childhood illness only a small proportion of symptoms result in a medical consultation. AIM: This pilot study set out to assess the influence of sociodemographic factors, social network, reason of choice of doctor and contact with allied health professionals on mothers' decisions to consult a general practitioner about their children's illnesses. METHOD: In one suburb of Melbourne, Australia all mothers with children aged 11 to 26 months were identified from the maternal and child health centre register. Mothers were invited for interview and if they attended were asked to keep a health diary for their child for four weeks. Logistic regression was used to test a multivariate model of factors predicting consultation with the general practitioner. RESULTS: A total of 150 mothers were identified. Interviews were carried out with 81% of target mothers and diary data collected for 72% of target children. Over the four-week diary period, consultation rates with the general practitioner were significantly higher if symptoms were recorded on 15 days or more, or the general practitioner had been recommended by a friend or was the mother's own doctor before the child's birth. Contact with a maternal and child health nurse was also a significant predictor of medical contact. Contact with friends and relatives, whether or not the study child was the first child in the family, mother's education, husband's occupational status or contact with a chemist were not significantly related to medical consultation rates. CONCLUSION: Choice of doctor (current doctor same as doctor before birth of child, or doctor recommended by a friend) resulted in significantly more consultations as did contact with a maternal and child health nurse. These factors would seem to require further study and inclusion in future models of consulting behaviour.

Computer skills and attitudes to computer-aided learning among medical students.

One hundred and forty-four third-year medical students at the University of Edinburgh were surveyed as to levels of computing skills and confidence in carrying out computing tasks. Attitudes to computer-aided learning for clinical teaching were also measured. Thirty-one per cent of students had not used a computer in the previous year and 38% had not used a computer outside supervised laboratory work. Twenty-two per cent had never used the university library computerized catalogue and 43% had never carried out a medline search using the library CD-ROM. Students were not confident of their ability to carry out simple computing tasks. Fifty-four per cent said they would need support or instruction in printing out a document, 69% were not confident they could copy a file onto a disk and 74% did not believe they could independently create a graph in a document. Students who had completed an intercalated honours year were significantly more skilled and confident in computing tasks. Attitudes to computer-aided learning were related to computing confidence. Medical students who have not acquired basic computer information technology (IT) skills by the third year of undergraduate training are unlikely to do so in the final hospital-based years. Undergraduate curricula for medical students must incorporate specific computer (IT) training.

Reducing hospital admission through computer supported education for asthma patients. Grampian Asthma Study of Integrated Care (GRASSIC).

OBJECTIVE: To evaluate a personalised computer supported education programme for asthma patients. DESIGN: Pragmatic randomised trial comparing outcomes over 12 months between patients taking part in an enhanced education programme (four personalised booklets, sent by post) and patients receiving conventional oral education at outpatient or surgery visits. SETTING: Hospital outpatient clinics and general practices in north east Scotland. SUBJECTS: 801 adults attending hospital outpatient clinics, with a diagnosis of asthma confirmed by a chest physician and pulmonary function reversibility of at least 20%. MAIN OUTCOME MEASURES: Numbers of hospital admissions, consultations with general practitioner for asthma, steroid courses used, bronchodilators and inhaled steroids prescribed, days of restricted activity, and disturbed nights. RESULTS: Patients with asthma judged too severe for randomisation between clinic care and integrated care and thus retained in clinic care had 54% fewer hospital admissions after receiving enhanced education than did the control group (95% confidence interval 30% to 97%; P < 0.05) over the study year. Patients had not all spent a full year as "educated" patients within the study year: when "educated days" were controlled for, annual admission rates for the entire enhanced education group were 49% (31% to 78%) of those in the control group. Among patients with sleep variation, sleep disturbance in the education group in the week before a regular review was 80% (65% to 97%) of that in the control group. There was no significant difference in days of restricted activity, prescription of bronchodilators or inhaled steroids, use of oral steroids, or number of general practitioner consultations for asthma, and no significant interaction between ownership of a peak flow meter and education. CONCLUSIONS: An asthma education programme based on computerised booklets can reduce hospital admissions and improve morbidity among hospital outpatients.
