Reducing alcohol-related harm in disadvantaged men: development and feasibility assessment of a brief intervention delivered by mobile telephone

Background

Socially disadvantaged men suffer substantial harm from heavy drinking. Brief alcohol interventions are effective in reducing consumption when delivered via health care. There is a need for tailored brief interventions for disadvantaged men who seldom attend health care.

Objectives

(1) To investigate the best ways to recruit and retain disadvantaged men in a study aimed at reducing the frequency of heavy drinking. (2) To identify the type of content and timing of the delivery that is most likely to engage disadvantaged young to middle-aged men in an intervention delivered by text messages. (3) To determine whether or not the intervention is likely to be an acceptable way to influence the frequency of heavy drinking.

Design

A three-phase study involving the development of the recruitment strategy and the intervention, an assessment of the feasibility of a randomised controlled trial, and a post-study evaluation.

Setting

Community-based study, conducted in Dundee, UK.

Participants

Disadvantaged men aged 25–44 years who had two or more episodes of heavy drinking (≥ 8 units in a single session) in the preceding month. Two recruitment strategies were employed: recruitment through general practice (GP) registers and recruitment through a community outreach strategy.

Interventions

Focus groups explored drinking motives and behaviours of the target group. The intervention also drew on reviews of the literature on: alcohol brief interventions, text message studies, communication theory and behaviour change theories and techniques. The intervention group received 36 text messages with images sent over a 28-day period.

Main outcome measures

The outcome measures evaluated the likely success of a full trial: recruitment of the participants; construction and delivery of a theoretically and empirically based intervention that successfully engages disadvantaged men; potential for the intervention to influence binge drinking.

Results

The focus group analyses identified that personal experience and knowledge of the harmful effects of alcohol was widespread. Furthermore, there was a discrepancy between frequent binge drinking and perceived social expectations and duties. This could usefully be targeted in the intervention. Theoretically and empirically based behaviour change strategies were successfully rendered in attractive, colourful, brief text messages. Both recruitment strategies (GP registers and community outreach) proved successful and a total of 67 men were recruited, exceeding the target of 60. The participants were at high risk of harm because of frequent episodes of heavy binge drinking. Baseline interviews established that those recruited through community outreach drank substantially more and had more frequent binge drinking sessions than those recruited through GP registers. Retention at follow-up was 96%. Extensive process evaluation was conducted. The evaluation showed that 95% of text messages were successfully delivered to participants' telephones. Furthermore, there was a high level of engagement with text messages which sought responses. Most men replied to these texts, often giving carefully structured personal responses. Analyses of the responses indicated a high level of engagement with key components of the behaviour change strategy. Post-trial evaluation showed high levels of satisfaction with the intervention.

Conclusions

This study has shown that disadvantaged men can be recruited and retained in an alcohol intervention trial. A theoretically and empirically based intervention was successfully delivered by text message. Furthermore, the messages were well received and elicited the types of response intended. A full trial of the intervention, incorporating a cost-effectiveness study, should be carried out.

Lessons from a randomized controlled trial designed to evaluate computer decision support software to improve the management of asthma

PRIMARY OBJECTIVE

To investigate whether computer decision support software used in the management of patients with asthma improves clinical outcomes.

RESEARCH DESIGN

Randomized controlled trial with practices each reporting on 30 patients with asthma over a 6 month period.

METHODS AND PROCEDURES

447 patients were randomly selected from practice asthma registers managed by 17 general practices from throughout the UK. Intervention practices used the software during consultations with these patients throughout the study while control practices did not.

MAIN OUTCOMES AND RESULTS

Practice consultations, acute exacerbations of asthma, hospital contacts, symptoms on assessment and medication use. A smaller proportion of patients within the intervention group initiated practice consultations for their asthma: 34 (22%) vs 111 (34%), odds ratio (OR) = 0.59, 95% confidence interval (CI) (0.37-0.95); and suffered acute asthma exacerbations: 12 (8%) vs 57 (17%), OR = 0.43, 95% CI = 0.21-0.85 six months after the introduction of the computer decision support software. There were no discernable differences in reported symptoms, maintenance prescribing or use of hospital services between the two groups.

CONCLUSION

The use of computer decision support software that implements guidelines during patient consultations may improve clinical outcomes for patients with asthma.

Scottish Asthma Management Initiative

OBJECTIVES

To describe the development process of a system that links audit, research and patient care and to detail the lessons learned from establishing a Scotland wide asthma management initiative.

DESIGN, SETTING AND SUBJECTS

Health Boards and practices throughout Scotland were invited to participate in an initiative which links review of care, guideline implementation, chronic disease management (CDM) approval and post-graduate education for doctors (PGEA) and nurses (PREP). Participating practices were given the materials to review 30 patients randomly selected from their asthma register. Health service resource use and drugs prescribed over a retrospective 12 month period were recorded for each patient using paper or electronic materials. All patients were invited for clinical assessment.

RESULTS

A two-tier management system proved effective. Twelve of the 15 Scottish health authorities agreed to recognise the audit for automatic CDM approval although the negotiation process was prolonged; 566 practices from all parts of Scotland have expressed an interest in the initiative. Provision of distance learning material linked to PGEA accreditation is free to general practitioners (GP's) and is a useful incentive for participation. To date 42 GPs have completed the distance learning element.

CONCLUSION

The Scottish Asthma Management Initiative has provided the opportunity for all sectors of the health service in Scotland to work together to explore innovative ways to improve the management and care of chronic disease. Participation in an initiative linked to guidelines, education and CDM approval is an excellent way to facilitate health professionals to improve care.

Effect of asthma and its treatment on growth: four year follow up of cohort of children from general practices in Tayside, Scotland

OBJECTIVE

To investigate whether asthma or its treatment impairs children's growth, after allowing for socioeconomic group.

DESIGN

4 year follow up of a cohort of children aged 1-15.

SETTING

12 general practices in the Tayside region of Scotland.

SUBJECTS

3347 children with asthma or features suggestive of asthma registered with the general practices.

MAIN OUTCOME MEASURES

Height and weight standard deviation scores.

RESULTS

Children who lived in areas of social deprivation (assessed by postcode) had lower height and weight than their contemporaries (mean standard deviation score -0.26 (SD 1.02) and -0.18 (1.15) respectively, P < 0.001 for both). Children who were receiving > or = 400 micrograms daily of inhaled steroids and who were attending both hospital and general practice for asthma care had lower height and weight than average, independent of the effect of deprivation (mean standard deviation score -0.62 (1.01), P = 0.002, for height and -0.58 (0.94), P = 0.005, for weight). Children receiving high doses of inhaled corticosteroids also showed lower growth rates (mean change in standard deviation score -0.19 (0.51), P = 0.003). However, no other children with asthma showed growth impairment.

CONCLUSION

Most children with asthma were of normal height and weight and had normal growth rates. However, children receiving high doses of inhaled steroids and requiring both general practice and hospital services had a significant reduction in their stature. This effect was independent from but smaller than the effect of socioeconomic group on stature.

Body mass index centile charts to assess fatness of British children

Body mass index (BMI) relates weight to height and reflects the shape of a child, but because of age dependency it has not been used conventionally for the estimation of fatness in children. From measurements of Tayside children (n = 34,533) centile charts were constructed for BMI (wt/ht2) from the raw data of height and weight, using Cole's LMS method for normalised growth standards. These data were compared with the only available European BMI charts published from data of French children obtained over a period of 24 years from 1956-79. British children appear to be 'fatter'. Within a subgroup (n = 445) the BMI values were correlated with estimations of body fat, for boys and girls, from skinfold thickness (r = 0.8 and 0.81) and bioelectrical impedance (r = 0.65 and 0.7). The limits of acceptable BMI have yet to be defined.
