Cost-effectiveness of strategies to market and train primary health care physicians in brief intervention techniques for hazardous alcohol use

Costs of Physician Continuous Professional Development: A Systematic Review

PURPOSE

An essential yet oft-neglected step in cost evaluations is the selection of resources (ingredients) to include in cost estimates. The ingredients that most influence the cost of physician continuous professional development (CPD) are unknown, as are the relative costs of instructional modalities. This study's purpose was to estimate the costs of cost ingredients and instructional modalities in physician CPD.

METHOD

The authors conducted a systematic review in April 2020, searching MEDLINE, Embase, PsycInfo, and the Cochrane Library for comparative cost evaluations of CPD for practicing physicians. Two reviewers, working independently, screened articles for inclusion and extracted information on costs (converted to 2021 U.S. dollars) for each intervention overall, each ingredient, and each modality.

RESULTS

Of 3,338 eligible studies, 62 were included, enumerating costs for 86 discrete training interventions or instructional modalities. The most frequently reported ingredients were faculty time (25 of 86 interventions), materials (24), administrator/staff time (23), and travel (20). Ingredient costs varied widely, ranging from a per-physician median of $4 for postage (10 interventions) to $525 for learner time (13); equipment (9) and faculty time were also relatively expensive (median > $170). Among instructional modalities (≤ 11 interventions per modality), audit and feedback performed by physician learners, computer-based modules, computer-based virtual patients, in-person lectures, and experiences with real patients were relatively expensive (median > $1,000 per physician). Mailed paper materials, video clips, and audit and feedback performed by others were relatively inexpensive (median ≤ $62 per physician). Details regarding ingredient selection (10 of 62 studies), quantitation (10), and pricing (26) were reported infrequently.

CONCLUSIONS

Some ingredients, including time, are more important (i.e., contribute more to total costs) than others and should be prioritized in cost evaluations. Data on the relative costs of instructional modalities are insightful but limited. The methods and reporting of cost valuations merit improvement.

A systematic review of approaches to improve practice, detection and treatment of unhealthy alcohol use in primary health care: a role for continuous quality improvement

BACKGROUND

Unhealthy alcohol use involves a spectrum from hazardous use (exceeding guidelines but no harms) through to alcohol dependence. Evidence-based management of unhealthy alcohol use in primary health care has been recommended since 1979. However, sustained and systematic implementation has proven challenging. The Continuing Quality Improvement (CQI) process is designed to enable services to detect barriers, then devise and implement changes, resulting in service improvements.

METHODS

We conducted a systematic review of literature reporting on strategies to improve implementation of screening and interventions for unhealthy alcohol use in primary care (MEDLINE EMBASE, PsycINFO, CINAHL, the Australian Indigenous Health InfoNet). Additional inclusion criteria were: (1) pragmatic setting; (2) reporting original data; (3) quantitative outcomes related to provision of service or change in practice. We investigate the extent to which the three essential elements of CQI are being used (data-guided activities, considering local conditions; iterative development). We compare characteristics of programs that include these three elements with those that do not. We describe the types, organizational levels (e.g. health service, practice, clinician), duration of strategies, and their outcomes.

RESULTS

Fifty-six papers representing 45 projects were included. Of these, 24 papers were randomized controlled trials, 12 controlled studies and 20 before/after and other designs. Most reported on strategies for improving implementation of screening and brief intervention. Only six addressed relapse prevention pharmacotherapies. Only five reported on patient outcomes and none showed significant improvement. The three essential CQI elements were clearly identifiable in 12 reports. More studies with three essential CQI elements had implementation and follow-up durations above the median; utilised multifaceted designs; targeted both practice and health system levels; improved screening and brief intervention than studies without the CQI elements.

CONCLUSION

Utilizing CQI methods in implementation research would appear to be well-suited to drive improvements in service delivery for unhealthy alcohol use. However, the body of literature describing such studies is still small. More well-designed research, including hybrid studies of both implementation and patient outcomes, will be needed to draw clearer conclusions on the optimal approach for implementing screening and treatment for unhealthy alcohol use.

Computerized Clinical Decision Support System for Prompting Brief Alcohol Interventions with Treatment Seeking Smokers: A Sex-Based Secondary Analysis of a Cluster Randomized Trial

Although brief alcohol intervention can reduce alcohol use for both men and women, health care providers (HCPs) are less likely to discuss alcohol use or deliver brief intervention to women compared to men. This secondary analysis examined whether previously reported outcomes from a cluster randomized trial of a clinical decision support system (CDSS)-prompting delivery of a brief alcohol intervention (an educational alcohol resource) for patients drinking above cancer guidelines-were moderated by patients' sex. Patients (n = 5702) enrolled in a smoking cessation program at primary care sites across Ontario, Canada, were randomized to either the intervention (CDSS) or control arm (no CDSS). Logistic generalized estimating equations models were fit for the primary and secondary outcome (HCP offer of resource and patient acceptance of resource, respectively). Previously reported results showed no difference between treatment arms in HCP offers of an educational alcohol resource to eligible patients, but there was increased acceptance of the alcohol resource among patients in the intervention arm. The results of this study showed that these CDSS intervention effects were not moderated by sex, and this can help inform the development of a scalable strategy to overcome gender disparities in alcohol intervention seen in other studies.

Implementation strategies to enhance management of heavy alcohol consumption in primary health care: a meta-analysis

BACKGROUND AND AIMS

Screening and brief interventions (SBI) delivered in primary health care (PHC) are cost-effective in decreasing alcohol consumption; however, they are underused. This study aims to identify implementation strategies that focus on SBI uptake and measure impact on: (1) heavy drinking and (2) delivery of SBI in PHC.

METHODS

Meta-analysis was conducted of controlled trials of SBI implementation strategies in PHC to reduce heavy drinking. Key outcomes included alcohol consumption, screening, brief interventions and costs in PHC. Predictor measures concerned single versus multiple strategies, type of strategy, duration and physician-only input versus that including mid-level professionals. Standardized mean differences (SMD) were calculated to indicate the impact of implementation strategies on key outcomes. Effect sizes were aggregated using meta-regression models.

RESULTS

The 29 included studies were of moderate methodological quality. Strategies had no overall impact on patients' reported alcohol consumption [SMD=0.07; 95% confidence interval (CI)=-0.02 to 0.16], despite improving screening (SMD=0.53; 95% CI=0.28-0.78) and brief intervention delivery (SMD=0.64;95% CI=0.27-1.02). Multi-faceted strategies, i.e. professional and/or organizational and/or patient-orientated strategies, seemed to have strongest effects on patients' alcohol consumption (P<0.05, compared with professional-orientated strategies alone). Regarding SBI delivery, combining professional with patient-orientated implementation strategies had the highest impact (P<0.05). Involving other staff besides physicians was beneficial for screening (P<0.05).

CONCLUSIONS

To increase delivery of alcohol screening and brief interventions and decrease patients' alcohol consumption, implementation strategies should include a combination of patient-, professional- and organizational-orientated approaches and involve mid-level health professionals as well as physicians.

Local Implementation of Alcohol Screening and Brief Intervention at Five Veterans Health Administration Primary Care Clinics: Perspectives of Clinical and Administrative Staff

BACKGROUND AND OBJECTIVE

Population-based alcohol screening, followed by brief intervention for patients who screen positive for unhealthy alcohol use, is widely recommended for primary care settings and considered a top prevention priority, but is challenging to implement. However, new policy initiatives in the U.S., including the Affordable Care Act, may help launch widespread implementation. While the nationwide Veterans Health Administration (VA) has achieved high rates of documented alcohol screening and brief intervention, research has identified quality problems with both. We conducted a qualitative key informant study to describe local implementation of alcohol screening and brief intervention from the perspectives of frontline adopters in VA primary care in order to understand the process of implementation and factors underlying quality problems.

METHODS

A purposive snowball sampling method was used to identify and recruit key informants from 5 VA primary care clinics in the northwestern U.S. Key informants completed 20-30 minute semi-structured interviews, which were recorded, transcribed, and qualitatively analyzed using template analysis.

RESULTS

Key informants (N=32) included: clinical staff (n=14), providers (n=14), and administrative informants (n=4) with varying participation in implementation of and responsibility for alcohol screening and brief intervention at the medical center. Ten inter-related themes (5 a priori and 5 emergent) were identified and grouped into 3 applicable domains of Greenhalgh's conceptual framework for dissemination of innovations, including values of adopters (theme 1), processes of implementation (themes 2 and 3), and post-implementation consequences in care processes (themes 4-10). While key informants believed alcohol use was relevant to health and important to address, the process of implementation (in which no training was provided and electronic clinical reminders "just showed up") did not address critical training and infrastructure needs. Key informants lacked understanding of the goals of screening and brief intervention, believed referral to specialty addictions treatment (as opposed to offering brief intervention) was the only option for following up on a positive screen, reported concern regarding limited availability of treatment resources, and lacked optimism regarding patients' interest in seeking help.

CONCLUSIONS

Findings suggest that the local process of implementing alcohol screening and brief intervention may have inadequately addressed important adopter needs and thus may have ultimately undermined, instead of capitalized on, staff and providers' belief in the importance of addressing alcohol use as part of primary care. Additional implementation strategies, such as training or academic detailing, may address some unmet needs and help improve the quality of both screening and brief intervention. However, these strategies may be resource-intensive and insufficient for comprehensively addressing implementation barriers.

Training and tailored outreach support to improve alcohol screening and brief intervention in Aboriginal Community Controlled Health Services

INTRODUCTION AND AIMS

Aboriginal Community Controlled Health Services (ACCHSs) are often the primary point of contact for Indigenous Australians experiencing alcohol-related harms. Screening and brief intervention (SBI) is a cost-effective treatment for reducing these harms. Factors influencing evidence-based alcohol SBI delivery in ACCHSs have been identified. Evaluations of strategies targeting these factors are required. The aim of this paper is to quantify the effect of training and tailored outreach support on the delivery of alcohol SBI in four Aboriginal Community Controlled Health Services (ACCHSs).

DESIGN AND METHODS

A pre- post- assessment of alcohol information recorded in computerised patient information systems of four ACCHSs.

RESULTS

For ACCHSs combined there was a statistically significant increase in the proportion of eligible clients with an electronic record of any alcohol information (3.2% to 7.5%, P < 0.0001) and a valid alcohol screen (1.6% to 6.5%, P < 0.0001), and brief intervention (25.75% to 47.7%, P < 0.0001). All four ACCHSs achieved statistically significant increases in the proportion of clients with a complete alcohol screen (10.3%; 7.4%; 2%, P < 0.0001 and 1.3%, P < 0.05), and two in the proportion with a heavy drinking screen (7% and 3.1%, P < 0.0001).

DISCUSSION AND CONCLUSIONS

Implementing evidence-based alcohol SBI in ACCHSs is likely to require multiple strategies tailored to the characteristics of specific services. Outreach support provided by local drug and alcohol practitioners and a one item heavy drinking screen offer considerable promise for increasing routine alcohol SBI delivery in ACCHSs. Training and outreach support appear to be effective for achieving modest improvements in alcohol SBI delivery in ACCHSs.

Increased documented brief alcohol interventions with a performance measure and electronic decision support

BACKGROUND

Alcohol screening and brief interventions (BIs) are ranked the third highest US prevention priority, but effective methods of implementing BI into routine care have not been described.

OBJECTIVES

This study evaluated the prevalence of documented BI among Veterans Affairs (VA) outpatients with alcohol misuse before, during, and after implementation of a national performance measure (PM) linked to incentives and dissemination of an electronic clinical reminder (CR) for BI.

METHODS

VA outpatients were included in this study if they were randomly sampled for national medical record reviews and screened positive for alcohol misuse (Alcohol Use Disorders Identification Test-Consumption score ≥5) between July 2006 and September 2008 (N=6788). Consistent with the PM, BI was defined as documented advice to reduce or abstain from drinking plus feedback linking drinking to health. The prevalence of BI was evaluated among outpatients who screened positive for alcohol misuse during 4 successive phases of BI implementation: baseline year (n=3504), after announcement (n=753) and implementation (n=697) of the PM, and after CR dissemination (n=1834), unadjusted and adjusted for patient characteristics.

RESULTS

Among patients with alcohol misuse, the adjusted prevalence of BI increased significantly over successive phases of BI implementation, from 5.5% (95% CI 4.1%-7.5%), 7.6% (5.6%-10.3%), 19.1% (15.4%-23.7%), to 29.0% (25.0%-33.4%) during the baseline year, after PM announcement, PM implementation, and CR dissemination, respectively (test for trend P<0.001).

CONCLUSIONS

A national PM supported by dissemination of an electronic CR for BI was associated with meaningful increases in the prevalence of documented brief alcohol interventions.

Institutionalization of brief alcohol intervention in primary health care-the Finnish case

BACKGROUND

There have been several research and practical projects to promote alcohol brief interventions (BIs) in healthcare settings, but no reports of nationwide outcome have so far been published. In Finland, these activities started in the early 1990s, and in the past years, the focus has been mainly on primary and occupational health care. The aim of the present study was to ascertain whether the extensive and long-lasting implementation efforts have led to the institutionalization of this activity among primary healthcare physicians and to the identification of factors that may be associated with it.

METHODS

The data were gathered by a questionnaire sent to all Finnish primary healthcare physicians in 2002 and 2007. In both years, the questionnaire contained questions on demographics, professional background and the physicians' own BI activity (regular, occasional, or none). In 2007, a question eliciting information about the change in BI activity during the past 5 years was added. The response rate was 67.1% (95% CI 65.4 to 68.8) (2,001/2,980) in 2002 and 50.9% (95% CI 49.2 to 52.6) (1,610/3,163) in 2007.

RESULTS

The number of physicians offering BI had increased during the study years from 59.2 to 78.5%. Regular activity was reported in 2002 by 9.3% of physicians and in 2007 by 17.2% and occasional activity correspondingly by 49.9 and 61.3%. Of the physicians who offered BI in 2007, 52.4% reported increased activity and 42.6% similar activity to that reported 5 years earlier. Having a specialist's license in general practice or occupational health care or long experience as a primary healthcare physician predicted high activity.

CONCLUSIONS

The BI activity of Finnish primary healthcare physicians is reasonably high and rising. Training and motivating those with low BI activity remains future challenge.

Developing, evaluating and implementing alcohol brief interventions in Europe

ISSUES

This article traces the history of research on the development, evaluation and implementation of alcohol brief intervention (BI) in Europe.

APPROACH

Narrative and historical review.

KEY FINDINGS

BI originated in Europe and, following a definition of opportunistic BI, early pioneering studies are summarised. The role of European scientists in the series of studies making up the WHO Collaborative Project on Detection and Management of Alcohol-related Problems in Primary Health Care (1982-2006) is then described, followed by a short account of a current EU-funded project (Primary Health European Project on Alcohol) with the aim of achieving a widespread, routine and enduring implementation of BI in EU member states. In addition to involvement in these two major projects, a great deal of research on BI has been carried out in a range of European countries and some of this research is noted.

IMPLICATIONS

Several European governments are now taking the rolling out of BI in routine services very seriously as a policy measure. There is no necessary conflict between widely available BI and alcohol control measures.

CONCLUSION

While much remains to be done regarding practical implementation, the mood of those interested in the promotion of BI as a means of reducing alcohol-related harm, in Europe as elsewhere, is cautiously optimistic.

The potential cost-effectiveness of general practitioner delivered brief intervention for alcohol misuse: evidence from rural Australia

OBJECTIVE

This paper aims to model General Practitioner (GP) delivered screening and brief intervention (BI), and to identify the costs per additional risky drinker who reduces alcohol consumption to low-risk levels, relative to current practice.

METHOD

A decision model and nine different scenarios were developed to assess outcomes and costs of GP-delivered screening and BI on the potential number of risky drinkers who reduce their alcohol consumption to low-risk levels in 10 rural communities in New South Wales, Australia.

FINDINGS

Based on evidence from current practice, approximately 19% of all risky drinkers visiting GPs annually would reduce alcohol consumption to low-risk levels, of which 0.7% would do so because of GP-delivered screening and BI. If rates of screening and BI are increased to 100%, 36% of these risky drinkers would reduce their drinking to low risk-levels. Alternatively, increments of 10% and 20% in GP-delivered screening and BI would reduce the proportion of risky drinkers by 2.1% and 4.2% respectively. The most cost-effective outcome per additional risky drinker reducing their drinking relative to current practice would be if all of these risky drinkers are screened alone with an ICER of AUD$197.

CONCLUSION

These findings indicate that increments in rates of screening and BI delivered by GPs can result in cost-effective reductions per additional risky drinkers reducing their drinking to low-risk levels, relative to current practice. They also imply that achieving substantial reductions in the prevalence of risky drinking in a community will require strategies other than opportunistic screening and BIs by GPs.

Reducing alcohol related harm experienced by Indigenous Australians: identifying opportunities for Indigenous primary health care services

OBJECTIVE

Identify key issues and opportunities relating to the dissemination of cost-effective interventions for alcohol in Indigenous-specific settings.

METHODS

Update previous reviews of the Indigenous alcohol literature, particularly in relation to intervention and dissemination studies aimed at identifying and integrating into routine clinical care those strategies that are most cost-effective in reducing alcohol-related harm.

RESULTS

The harmful use of alcohol has been identified as a major public health issue, which has a disproportionately high negative impact on Indigenous Australians. While the disproportionately high burden of harm borne by Indigenous Australian communities is well documented in descriptive studies, attempts to redress this imbalance through well controlled intervention and dissemination studies appear to have been inadequate to date. There is compelling evidence from the non-Indigenous community that brief intervention is an effective treatment for harmful alcohol use, compared to the relatively lower levels of evidence for primary and tertiary level interventions. The effectiveness of brief intervention for alcohol in Indigenous Australian communities should, therefore, be examined.

CONCLUSIONS AND IMPLICATIONS

An opportunity exists to implement brief intervention into Indigenous primary health care settings, as an evidence-based strategy using established resources. There is the possibility that such Indigenous-specific health services research will lead the dissemination field in demonstrating how the implementation process can be successfully tailored to specific and defined clinical settings.

Alcohol prevention within primary care in municipalities in the state of Minas Gerais, Southeastern Brazil

OBJECTIVE

To evaluate the effectiveness of implementing screening strategies associated with brief interventions for prevention of alcohol abuse, within primary healthcare.

METHODS

This evaluation study was conducted among 113 primary healthcare professionals and managers in three municipalities in the Zona da Mata of Minas Gerais, Southeastern Brazil, in 2007. The health professionals participated in a training to perform screening associated with brief interventions for alcohol use prevention. Six months after this training, a follow-up evaluation was carried out. The qualitative assessment involved participant observation, interviews with managers before the training and during the follow-up, and focus groups with healthcare professionals during the follow-up. The content analysis technique was applied. The following instruments were used for the quantitative assessment: Objective Knowledge Questionnaire, Moralization Scale for Alcohol Use, Perception Model for Alcohol Use Questionnaire and Preventive Practices for Alcohol Use Questionnaire. The municipalities were compared before the training and during the follow-up, and longitudinal evaluations were performed in each municipality, using descriptive and inferential statistics.

RESULTS

Participation by the managers and integration among the health professionals regarding the practices of screening and brief intervention were associated with greater effectiveness of implementation. This occurred in one of the municipalities, in which there was a significant decrease in the degree to which alcohol use was moralized by the healthcare professionals, in comparison with the other municipalities. In the other municipalities, the effects of the implementation process for the project indicated that the frequency of performing preventive practices against alcohol use increased, along with the health professionals' knowledge, although not enough to indicate effective implementation.

CONCLUSIONS

Effectiveness in implementing alcohol prevention strategies in primary healthcare services is associated with managers' engagement in the implementation process for these strategies.

Disseminating best-evidence health-care to Indigenous health-care settings and programs in Australia: identifying the gaps

Indigenous Australians experience a disproportionately greater burden of harm from smoking, poor nutrition, alcohol misuse and physical inactivity (SNAP risk factors) than the general Australian population. A critical step in further improving efforts to reduce this harm is to review existing efforts aimed at increasing the uptake of evidence-based interventions in Indigenous-specific health-care settings and programs. This study systematically identifies and reviews published Indigenous-specific dissemination studies targeting SNAP interventions. An electronic search of eight databases and a manual search of reference lists of previous literature reviews were undertaken. Eleven dissemination studies were identified for review: six for nutrition and physical activity as a component of diabetes care, three for alcohol and two for smoking. The majority of studies employed continuing medical education (n = 9 studies), suggesting that improving health-care providers' knowledge and skills is a focus of current efforts to disseminate best-evidence SNAP interventions in Indigenous health-care settings. Only two studies evaluated reminder systems, despite their widespread use in Indigenous-specific health-care services, and only one study employed academic detailing, despite its cost-effectiveness at modifying health-care provider behavior. There is a clear need for more Indigenous-specific dissemination research targeting the uptake of secondary prevention and to establish reliable and valid measures of Indigenous-specific health-care delivery, in order to determine which dissemination strategies are most likely to be effective in Indigenous health-care settings and programs.

Encouraging physicians to screen for and intervene in substance use disorders: obstacles and strategies for change

The scientific literature was reviewed to identify obstacles and effective ways to improve primary care physician screening, interventions, and management of patient substance use disorders (SUDs). Major obstacles identified are physician lack of skills and self-efficacy in patient counseling, inadequate training at all levels of medical education, and lack of reimbursement and other health care systems support for services to patients. Physician abuse of drugs does not appear to be a major obstacle. Physician attitudes about patients with SUDS and the effectiveness of treatment services need to be addressed. Research points to the use of a multifaceted change strategy. Key components include practice-based training emphasizing screening and counseling skills throughout medical education, clinical systems to ensure regular SUD services (screening, intervention, and referral) to patients, and reimbursement and coverage systems to support physician interventions and patient services.

The cost-effectiveness and cost-benefit of screening and brief intervention for unhealthy alcohol use in medical settings

Economic evaluation can be a valuable tool for assessing the efficiency and value of health care programs. To examine the literature on the economic evaluation of alcohol screening and brief intervention in medical settings, relevant studies were identified in the MEDLINE database (1966 through November 2006) and by hand-searching the references of identified articles and relevant journals. The 15 identified studies used a range of economic evaluation methods, including cost analysis, cost-benefit, cost-effectiveness, and cost-utility. Nearly all of the studies supported the use of alcohol screening and brief intervention. The studies that prospectively collected cost and effect data and/or conformed closely to methodological guidelines demonstrated a strong economic benefit of alcohol screening and brief intervention when compared to usual care. Overall, the reviewed studies support alcohol SBI in medical settings as a wise use of health care resources and illustrate the usefulness of economic evaluation for assessing alcohol prevention and treatment programs.

Screening, Brief Intervention, and Referral to Treatment (SBIRT): toward a public health approach to the management of substance abuse

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a comprehensive and integrated approach to the delivery of early intervention and treatment services through universal screening for persons with substance use disorders and those at risk. This paper describes research on the components of SBIRT conducted during the past 25 years, including the development of screening tests, clinical trials of brief interventions and implementation research. Beginning in the 1980s, concerted efforts were made in the US and at the World Health Organization to provide an evidence base for alcohol screening and brief intervention in primary health care settings. With the development of reliable and accurate screening tests for alcohol, more than a hundred clinical trials were conducted to evaluate the efficacy and cost effectiveness of alcohol screening and brief intervention in primary care, emergency departments and trauma centers. With the accumulation of positive evidence, implementation research on alcohol SBI was begun in the 1990s, followed by trials of similar methods for other substances (e.g., illicit drugs, tobacco, prescription drugs) and by national demonstration programs in the US and other countries. The results of these efforts demonstrate the cumulative benefit of translational research on health care delivery systems and substance abuse policy. That SBIRT yields short-term improvements in individuals' health is irrefutable; long-term effects on population health have not yet been demonstrated, but simulation models suggest that the benefits could be substantial.

Estratégias de rastreamento e intervenções breves para problemas relacionados ao abuso de álcool entre bombeiros

Efeitos deletérios do abuso do álcool são amplamente conhecidos e descritos. A prevenção ao abuso de álcool é particularmente importante em categorias profissionais específicas, por exemplo, trabalhadores submetidos a situações de risco e estresse constantes, como bombeiros. A prevenção pode ser crucial para reduzir possíveis conseqüências do abuso de álcool nessas categorias profissionais. Neste trabalho, ilustramos o uso de uma abordagem em particular, o programa de Triagem e Intervenção Breve (TIB) para bombeiros de Juiz de Fora, MG. A TIB foi realizada em associação com outras avaliações, com um fluxo de intervenção aos bombeiros. Nossa proposta se mostrou factível e sistematizou o atendimento aos mesmos, de forma que permitiu uma integração deste tipo de procedimento com as atividades do setor de saúde. Sugerimos que a TIB, em se tratando de problemas relacionados ao abuso de álcool, se mostrou eficaz neste contexto.

The methodological quality of economic evaluations of guideline implementation into clinical practice: a systematic review of empiric studies

OBJECTIVES

Despite the emphasis on efficiency of health-care services delivery, there is an imperfect evidence base to inform decisions about whether and how to develop and implement guidelines into clinical practice. In general, studies evaluating the economics of guideline implementation lack methodological rigor. We conducted a systematic review of empiric studies to assess advances in the economic evaluations of guideline implementation.

METHODS

The Cochrane Effective Professional and Organisational Change Group specialized register and the MEDLINE database were searched for English publications between January 1998 and July 2004 that reported objective effect measures and implementation costs. We extracted data on study characteristics, quality of study design, and economic methodology. It was assessed whether the economic evaluations followed methodological guidance.

RESULTS

We included 24 economic evaluations, involving 21 controlled trials and three interrupted time series designs. The studies involved varying settings, targeted professionals, targeted behaviors, clinical guidelines, and implementation strategies. Overall, it was difficult to determine the quality of study designs owing to poor reporting. In addition, most economic evaluations were methodologically flawed: studies did not follow guidelines for evaluation design, data collection, and data analysis.

CONCLUSIONS

The increasing importance of the value for money of providing health care seems to be reflected by an increase in empiric economic evaluations of guideline implementation. Because of the heterogeneity and poor methodological quality of these studies, however, the resulting evidence is still of limited use in decision-making. There seems to be a need for more methodological guidance, especially in terms of data collection and data synthesis, to appropriately evaluate the economics of developing and implementing guidelines into clinical practice.

Effectiveness of strategies to implement brief alcohol intervention in primary healthcare. A systematic review

OBJECTIVE

To review systematically the available literature on implementation of brief alcohol interventions in primary healthcare in order to determine the effectiveness of the implementation efforts by the health are providers. KEY QUESTION: To what extent have the efforts to implement brief alcohol interventions in primary healthcare environments been successful?

METHOD

Literature search from Medline, Cinahl, PsychLIT, Cochrane.

SETTING

Primary healthcare.

MATERIAL

A total of 11 studies encompassing 921 GPs, 266 nurses, 88 medical students, and 44 "non-physicians" from Europe, the USA, and Australia.

MAIN OUTCOME MEASURES

Material utilization, screening, and brief intervention rates.

ANSWER

Intervention effectiveness (material utilization, screening, and brief intervention rates) generally increased with the intensity of the intervention effort, i.e. the amount of training and/or support provided. Nevertheless, the overall effectiveness was rather modest. However, the studies examined were too heterogeneous, not scientifically rigorous enough, and applied too brief follow-up times to provide conclusive answers.

Modelling the costs and outcomes of changing rates of screening for alcohol misuse by GPs in the Australian context

AIM

To assess the relative cost effectiveness of four strategies (academic detailing, computerised reminder systems, target payments and interactive continuing medical education) to increase the provision of screening and brief interventions by Australian GPs with the ultimate goal of decreasing risky alcohol consumption among their patients.

METHODS

This project used a modelling approach to combine information on the effectiveness and costs of four separate strategies to change GP behaviours to estimate their relative cost effectiveness.

RESULTS

The computerised reminder system and academic detailing appear most effective in achieving a decrease in the number of standard drinks consumed by risky drinkers.

CONCLUSION

Regardless of the assumptions made, the targeted payment strategy appeared to be the least cost-effective method to achieve a decrease in risky alcohol consumption while the other three strategies appear reasonably comparable.

Training medical providers to conduct alcohol screening and brief interventions

Although progress has been made in developing a scientific basis for alcohol screening and brief intervention (SBI), training packages are necessary for its widespread dissemination in primary care settings. This paper evaluates a training package developed for the Cutting Back SBI program. Three groups of medical personnel were compared before and after SBI training: physicians (n = 44), medical students (n = 88), and non-physicians (n = 41). Although the training effects were at times dependent on group membership, all changes were in a direction more conducive to implementing SBI. Physicians and medical students increased confidence in performing screening procedures, and students increased self-confidence in conducting brief interventions. Non-physicians perceived fewer obstacles to screening patients after training. Trained providers reported conducting significantly more SBI than untrained providers, and these differences were consistent with patients' reports of their providers' clinical activity. Thus, when delivered in the context of a comprehensive SBI implementation program, this training is effective in changing providers' knowledge, attitudes, and practice of SBI for at-risk drinking.

Screening in brief intervention trials targeting excessive drinkers in general practice: systematic review and meta-analysis

OBJECTIVE

To determine the effectiveness of programmes of screening in general practice for excessive alcohol use and providing brief interventions.

DESIGN

Systematic review and meta-analysis of randomised controlled trials that used screening as a precursor to brief intervention.

SETTING

General practice.

MAIN OUTCOME MEASURES

Number needed to treat, proportion of patients positive on screening, proportion given brief interventions, and effect of screening.

RESULTS

The eight studies included for meta-analysis all used health questionnaires for screening, and the brief interventions included feedback, information, and advice. The studies contained several sources of bias that might lead to overestimates of the effects of intervention. External validity was compromised because typically three out of four people identified by screening as excessive users of alcohol did not qualify for the intervention after a secondary assessment. Overall, in 1000 screened patients, 90 screened positive and required further assessment, after which 25 qualified for brief intervention; after one year 2.6 (95% confidence interval 1.7 to 3.4) reported they drank less than the maximum recommended level.

CONCLUSIONS

Although even brief advice can reduce excessive drinking, screening in general practice does not seem to be an effective precursor to brief interventions targeting excessive alcohol use. This meta-analysis raises questions about the feasibility of screening in general practice for excessive use of alcohol.

Cost effectiveness of brief interventions for reducing alcohol consumption

The direct costs and health effects of a primary-care-based brief intervention for hazardous alcohol consumption were examined. The total cost of the intervention was calculated from costs associated with: marketing the intervention programme; providing training and support in the use of the intervention materials; physician time required for providing brief advice for 'at-risk' drinkers. The effect of the intervention on health outcomes was expressed in terms of number of life years saved by preventing alcohol-related deaths. This was derived by combining estimates of the impact of the programme if it were implemented nationally with available evidence on the health effects of excess alcohol consumption. Results are based on international trial evidence showing the physical resources required by the intervention and its effectiveness combined with Australian price data. The costs associated with screening and brief advice using the current intervention programme range from Aus$19.14 to Aus$21.50. The marginal costs per additional life year saved were below Aus$1873. The robustness of the model used is supported by an extensive sensitivity analysis. In comparison with existing health promotion strategies the costs and effects of the current intervention are highly encouraging.

Use of marketing to disseminate brief alcohol intervention to general practitioners: promoting health care interventions to health promoters

Health research findings are of little benefit to patients or society if they do not reach the audience they are intended to influence. Thus, a dissemination strategy is needed to target new findings at its user group and encourage a process of consideration and adoption or rejection. Social marketing techniques can be utilized to aid successful dissemination of research findings and to speed the process by which new information reaches practice. Principles of social marketing include manipulating the marketing mix of product, price, place and promotion. This paper describes the development of a marketing approach and the outcomes from a trial evaluating the effectiveness and cost-effectiveness of manipulating promotional strategies to disseminate actively a screening and brief alcohol intervention (SBI) programme to general practitioners (GPs). The promotional strategies consisted of postal marketing, telemarketing and personal marketing. The study took place in general practices across the Northern and Yorkshire Regional Health Authority. Of the 614 GPs eligible for the study, one per practice, 321 (52%) took the programme and of those available to use it for 3 months (315), 128 (41%) actively considered doing so, 73 (23%) actually went on to use it. Analysis of the specific impact of the three different promotional strategies revealed that while personal marketing was the most effective overall dissemination and implementation strategy, telemarketing was more cost-effective. The findings of our work show that using a marketing approach is promising for conveying research findings to GPs and in particular a focus on promotional strategies can facilitate high levels of uptake and consideration in this target group.

Hazardous alcohol use: its delineation as a subthreshold disorder, and approaches to its diagnosis and management

The last 20 years have seen a significant paradigm shift in how we view alcohol misuse. The dichotomous model of "alcoholism" and "normal drinking" has now been replaced by the concept of a spectrum of disorders. In this new framework, "hazardous alcohol use" is defined as a repeated pattern of drinking that confers the risk of harmful consequences. It is a typical example of a subthreshold disorder. Where actual physical or psychological harm or social problems have occurred, the terms "harmful alcohol use" and "alcohol abuse," respectively, are applied. These conditions would typically be considered to be above the clinical threshold. The most severe disorder, alcohol dependence, is a psychobiological syndrome with often severe physical, psychological, and social sequelae. This article describes how the concept of hazardous alcohol use originated, and reviews the intervention techniques that have been developed to induce and assist hazardous drinkers to reduce their consumption to nonhazardous levels. The findings from a series of World Health Organization (WHO) collaborative studies on brief interventions for hazardous alcohol use are described. This work has resulted in the development of the Alcohol Use Disorders Identification Test (AUDIT) screening instrument, which can detect over 90% of hazardous drinkers in a range of settings, and the demonstration that 5 minutes' structured advice can reduce hazardous consumption by 30%. The later phases of this program of work have examined strategies to promote the dissemination of brief interventions for hazardous alcohol use throughout primary health care, and the nationwide, systematic, and sustained utilization of these interventions.
