Medical communication and technology: a video-based process study of the use of decision aids in primary care consultations.

BACKGROUND: Much of the research on decision-making in health care has focused on consultation outcomes. Less is known about the process by which clinicians and patients come to a treatment decision. This study aimed to quantitatively describe the behaviour shown by doctors and patients during primary care consultations when three types of decision aids were used to promote treatment decision-making in a randomised controlled trial. METHODS: A video-based study set in an efficacy trial which compared the use of paper-based guidelines (control) with two forms of computer-based decision aids (implicit and explicit versions of DARTS II). Treatment decision concerned warfarin anti-coagulation to reduce the risk of stroke in older patients with atrial fibrillation. Twenty nine consultations were video-recorded. A ten-minute 'slice' of the consultation was sampled for detailed content analysis using existing interaction analysis protocols for verbal behaviour and ethological techniques for non-verbal behaviour. RESULTS: Median consultation times (quartiles) differed significantly depending on the technology used. Paper-based guidelines took 21 (19-26) minutes to work through compared to 31 (16-41) minutes for the implicit tool; and 44 (39-55) minutes for the explicit tool. In the ten minutes immediately preceding the decision point, GPs dominated the conversation, accounting for 64% (58-66%) of all utterances and this trend was similar across all three arms of the trial. Information-giving was the most frequent activity for both GPs and patients, although GPs did this at twice the rate compared to patients and at higher rates in consultations involving computerised decision aids. GPs' language was highly technically focused and just 7% of their conversation was socio-emotional in content; this was half the socio-emotional content shown by patients (15%). However, frequent head nodding and a close mirroring in the direction of eye-gaze suggested that both parties were active participants in the conversation CONCLUSION: Irrespective of the arm of the trial, both patients' and GPs' behaviour showed that they were reciprocally engaged in these consultations. However, even in consultations aimed at promoting shared decision-making, GPs' were verbally dominant, and they worked primarily as information providers for patients. In addition, computer-based decision aids significantly prolonged the consultations, particularly the later phases. These data suggest that decision aids may not lead to more 'sharing' in treatment decision-making and that, in their current form, they may take too long to negotiate for use in routine primary care.

Seeing through the glass darkly? A qualitative exploration of GPs' drinking and their alcohol intervention practices.

BACKGROUND: Brief alcohol intervention is influenced by patients' personal characteristics as well as their clinical risk. Risk-drinkers from higher social-status groups are less likely to receive brief intervention from GPs than those from lower social-status groups. Thus GPs' perception of social similarity or distance may influence brief intervention. OBJECTIVE: To explore the role that GPs' drinking behaviour plays in their recognition of alcohol-related risk in patients. METHOD: A qualitative interview study with 29 GPs recruited according to maximum variation sampling. All interviews were audio-recorded and transcribed verbatim. Analysis was inductive with constant comparison within and between themes plus deviant case analysis. Analysis developed until category saturation was reached. RESULTS: GPs described a range of personal drinking practices that broadly mirrored population drinking patterns. Many saw themselves as part of mainstream society, sharing in culturally sanctioned behaviour. For some GPs, shared drinking practices could increase empathy for patients who drank, and facilitate discussion about alcohol. However, several GPs regarded themselves as distinct from 'others', separating their own drinking from that of patients. Several GPs described a form of bench-marking, wherein only patients who drank more, or differently, to themselves were felt to be 'at risk'. CONCLUSION: Alcohol is clearly a complex and emotive health and social issue and GPs are not immune to its effects. For some GPs' shared drinking behaviour can act as a window of opportunity enabling insight on alcohol issues and facilitating discussion. However, other GPs may see through the glass more darkly and selectively recognize risk only in those patients who are least like them.

Effectiveness of nurse-led brief alcohol intervention: a cluster randomized controlled trial.

AIM: This paper reports an evaluation of the effectiveness and cost-effectiveness of nurse-led screening and brief intervention in reducing excessive alcohol consumption among patients in primary health care. BACKGROUND: Excessive alcohol consumption is a major source of social, economic and health problems. However, such consumption is responsive to brief alcohol intervention. To date, brief intervention research in primary health care has focused on general practitioner-led interventions, and there is only circumstantial evidence of effectiveness in nurse-led interventions. However, nurses are increasingly taking a lead in health promotion work in primary care. METHODS: A pragmatic cluster-randomized controlled trial was carried out between August 2000 and June 2003 to evaluate the effects of a brief intervention compared with standard advice (control condition). A total of 40 general practice clusters (intervention = 21 and control = 19) recruited 127 patients (intervention = 67 and control = 60) to the trial. Excessive consumption was identified opportunistically via the Alcohol Use Disorders Identification Test. After baseline assessment, patients received either a 5-10 minutes brief intervention using the 'Drink-Less' protocol or standard advice (control condition). Follow-up occurred at 6 and 12 months postintervention. RESULTS: Analysis of variance weighted for cluster size revealed no statistically significant differences between intervention and control patients at follow up. A majority of patients in both conditions reduced their alcohol consumption between assessment and subsequent measurement. Economic analysis suggested that the brief intervention led to no statistically significant changes in subsequent health service resource use relative to standard treatment. CONCLUSION: The brief intervention evaluated in this trial had no effect over standard advice delivered by nurses in primary health care. However, there was a reduction in excessive drinking across both arms of the trial over time. Due to nurse drop-out, this trial was significantly underpowered. Future research should explore barriers to nurses' involvement in research trials, particularly with an alcohol focus. A larger trial is required to evaluate the effectiveness of nurse-led screening and brief alcohol intervention in primary care.

Patients or research subjects? A qualitative study of participation in a randomised controlled trial of a complex intervention.

OBJECTIVE: To explore participants' understandings regarding treatment decisions, made within an efficacy randomised controlled trial (RCT) of decision-support tools. METHODS: Qualitative study: interviews (audio-recorded) with participants. Participants were interviewed 3-5 days after using a decision-support tool (n=30) and again at 3 months (n=26). Transcripts were analysed using a constant comparative approach. RESULTS: Participants' understandings were shaped by the ways in which they made sense of their participation. Participants made attributions about their trial identity that fell on a continuum. At one end we found participants who identified as 'experienced medical volunteers', and at the other those who identified as 'real patients'. In the participants' accounts, a trial identity of 'patient' accompanied an expectation that the decision-support tools offered a means of making treatment decisions. 'Volunteers', however, saw the interventions as tasks to be completed for the purposes of the trial team. CONCLUSION: In our study, trial identity shaped participants' understandings regarding treatment decisions and all other aspects of the trial. PRACTICE IMPLICATIONS: Different understandings regarding the appropriate response to trial tasks may affect behaviour and therefore outcomes in some trials. Further research is required to unravel the relationship between trial identities, understanding and behaviour.

A multicountry controlled trial of strategies to promote dissemination and implementation of brief alcohol intervention in primary health care: findings of a World Health Organization collaborative study.

OBJECTIVE: This study examines the impact of marketing strategies on the dissemination of a brief alcohol intervention program to general practitioners (GPs). The marketing strategy was tested to determine the most effective way to promote awareness about and consideration of a brief alcohol intervention program. The study also examines the impact of training and support strategies to promote the program's implementation in routine primary care. METHOD: A pragmatic trial was carried out in Australia, Belgium (Flanders), Denmark, England, New Zealand and Spain (Catalonia) in which GPs were randomly allocated into one of three marketing conditions (direct mail, telemarketing and academic detailing [personal visits]). The GPs who requested a brief intervention program and agreed to use it were stratified by previous marketing condition and randomly allocated into one of three implementation strategy groups: written guidance, outreach training and outreach training plus ongoing telephone support. RESULTS: Acceptance of the brief intervention program was more effective with use of telemarketing (65%) and academic detailing (67%) than with direct mail (32%) for promoting awareness about and consideration of a brief alcohol intervention program. The median proportion of patients screened was higher for trained GPs (6%) and supported GPs (9%) than for control GPs (1%), who received only written guidance on how to conduct brief intervention. Similarly, the median rate for giving advice to at-risk patients was higher for trained GPs (3%) and supported GPs (3%) than for control GPs (0%). CONCLUSIONS: The adoption of more direct approaches for disseminating evidence-based intervention programs to GPs is a necessary first step for changing practice behavior. However, outreach training was required to promote actual use of a new procedure in routine practice.

Engaging general practitioners in the management of hazardous and harmful alcohol consumption: results of a meta-analysis.

OBJECTIVE: A systematic review was undertaken of studies that test the effectiveness of different strategies used to increase general practitioners' rates of screening for and giving advice about hazardous and harmful alcohol consumption. METHOD: Resources were MEDLINE, EMBASE, Cinahl and the Cochrane Library (1966-2001). Inclusion criteria were those of the Effective Practice and Organisation of Care Group of the Cochrane Collaboration. A meta-analysis was undertaken, using a random effects model, of 15 programs identified in 12 trials. Effect sizes, calculated using the logged odds ratio, were adjusted by inverse variance weights to control for the sample sizes of the studies. RESULTS: Analysis of the intervention groups resulted in screening and advice-giving rates of 45% (95% CI: 33%-56%) and analysis of the comparison groups resulted in rates of 32% (95% CI: 20%-43%). The weighted mean effect size (logged odds ratio = 0.73; 95% CI: 0.56-0.90) was heterogeneous. Regression analysis to explain the heterogeneity found a significant effect for alcohol-specific programs compared with general prevention programs in which alcohol was included, and for multicomponent programs compared with single component programs. No significant differences were found between educational-based or office-based interventions. CONCLUSIONS: Although the small numbers of programs studied suggest caution be used in interpreting the results, it seems it is possible to increase the engagement of general practitioners in screening and giving advice for hazardous and harmful alcohol consumption. Although considerably more research of high quality is needed, promising programs are those that have a specific focus on alcohol and those that are multicomponent.

Promoting brief alcohol intervention by nurses in primary care: a cluster randomised controlled trial.

This trial evaluated the clinical impact and cost-effectiveness of strategies promoting screening and brief alcohol intervention (SBI) by nurses in primary care. Randomisation was at the level of the practice and the interventions were: written guidelines (controls, n=76); outreach training (n=68); and training plus telephone-based support (n=68). After 3 months, just 39% of controls implemented the SBI programme compared to 74% of nurses in trained practices and 71% in trained and supported practices. Controls also screened fewer patients and delivered fewer brief interventions to risk drinkers than other colleagues. However, there was a trade-off between the extent and the appropriateness of brief intervention delivery with controls displaying the least errors in overall patient management. Thus cost-effectiveness ratios (cost per patient appropriately treated) were similar between the three strategies. Given the potential for anxiety due to misdirected advice about alcohol-related risk, the balance of evidence favoured the use of written guidelines to promote SBI by nurses in primary care.

Implementation of a model for service delivery and organisation in mental healthcare: a qualitative exploration of service provider views.

The purpose of the present study was to investigate factors influencing the implementation of a model for service delivery and organisation in mental healthcare. A qualitative case-study approach was employed involving in-depth interviews with 25 service providers from across mental health and social care in one local authority area in northern England. Purposive sampling achieved a broad coverage across geographical areas, voluntary and statutory services, and primary, secondary and specialist mental healthcare. The findings indicate that implementation was influenced by three interrelated factors: the means by which the model was introduced to the workforce; use of the model itself by service providers; and the broader service context. Thus, negative reactions to the way the model was initially presented strongly influenced service providers' subsequent views of it. Moreover, observations regarding the broader context of mental healthcare revealed a service that was ill-equipped to manage change because of over-stretched resources and that was disinclined to accept imposed change because of poor staff morale. Finally, differential interpretation of the model's tiers by service providers led to defensive practice that manifested itself as over-referral of service users within the system. Changing practice behaviour is a complex process, particularly at a service level that consists of numerous professional groups with differing cultural norms. Successful reorganisation of services is unlikely if those responsible for delivering care are not part of the process of change. Moreover, unsuccessful attempts to change professional practice may exacerbate existing tensions within a workforce, which may be to the detriment of those requiring care. A full diagnostic analysis of the system, including service providers' concerns, should be carried out before introducing change or reconfiguring services.

A qualitative study of nurses' attitudes and practices regarding brief alcohol intervention in primary health care.

BACKGROUND: Excessive alcohol consumption causes significant mortality, morbidity, economic and social problems in the United Kingdom (UK). Despite strong evidence for the effectiveness of brief intervention to reduce excessive drinking in primary health care, there is little indication that such intervention routinely occurs. AIMS: This study aimed to explore primary health care nurses' attitudes and practices regarding brief alcohol intervention in order to understand why it is underexploited. METHODS: The study design was qualitative, using a grounded theory approach to data collection and analysis. Semi-structured in-depth interviews were conducted with 24 nurses from practices that had previously been involved in a General Practitioner (GP) led brief alcohol intervention trial in the North-east of England. A combination of convenience and purposive sampling was used to recruit subjects and gain a broad range of perspectives on issues emerging from ongoing data-analysis until data saturation occurred. RESULTS: It was clear that although primary health care nurses have many opportunities to engage in alcohol intervention, most have received little or no preparation for this work. This has left nurses at a disadvantage as alcohol consumption is a confusing and emotive area for both health professionals and patients. An analysis of factors influencing nurse involvement in alcohol intervention outlined a requirement for clear health messages about alcohol, training in intervention skills, facilitation to enhance confidence regarding intervention and support to help deal with negative patient reactions. CONCLUSIONS: As current health policy is to encourage, sustain and extend the health promotion and public health role of primary care nurses, more attention should be given to providing them with better preparation and support to carry out such work.

Attitudes and management of alcohol problems in general practice: descriptive analysis based on findings of a World Health Organization international collaborative survey.

AIMS: To determine if general practitioners' (GPs) experience of education on alcohol, support in their working environment for intervening with alcohol problems, and their attitudes have an impact on the number of patients they manage with alcohol problems. METHODS: 1300 GPs from nine countries were surveyed with a postal questionnaire as part of a World Health Organization (WHO) collaborative study. RESULTS: GPs who received more education on alcohol (OR = 1.5; 95% CI, 1.3-1.7), who perceived that they were working in a supportive environment (OR = 1.6; 95% CI, 1.4-1.9), who expressed higher role security in working with alcohol problems (OR = 2.0; 95% CI, 1.5-2.5) and who reported greater therapeutic commitment to working with alcohol problems (OR = 1.4; 95% CI, 1.1-1.7) were more likely to manage patients with alcohol-related harm. CONCLUSION: Both education and support in the working environment need to be provided to enhance the involvement of GPs in the management of alcohol problems.

Attitudes and managing alcohol problems in general practice: an interaction analysis based on findings from a WHO collaborative study.

AIMS: To determine if GPs' attitudes towards working with drinkers moderated the impact that training and support had on screening and brief intervention activity in routine practice. METHODS: Subjects were 340 GPs from four countries who were part of a World Health Organization randomized controlled trial to evaluate the effectiveness of training and support in increasing screening and brief alcohol intervention. GPs' self-reported attitudes towards working with drinkers were measured with the Shortened Alcohol and Alcohol Problems Perception Questionnaire. RESULTS: Whereas training and support increased GPs' screening and brief intervention rates, it did so only for practitioners who already felt secure and committed in working with drinkers. Training and support did not improve attitudes towards working with drinkers and, moreover, worsened the attitudes of those who were already insecure and uncommitted. CONCLUSIONS: To enhance the involvement of GPs in the management of alcohol problems, interventions that increase both actual experience and address practitioners' attitudes is required. Such support could take the form of on-site support agents and facilitators.
