Abstract
INTRODUCTION Prenatal exposure to alcohol can cause lifelong physical and cognitive challenges in the form of fetal alcohol syndrome and other fetal alcohol spectrum disorders (FASDs). The prevention of prenatal alcohol exposure is thus a public health priority - and one that should account for the particular needs of subpopulations, including in American Indian/Alaska Native (AI/AN) communities. Prior to conception, alcohol-exposed pregnancy prevention is accomplished by encouraging the reduction or elimination of risky alcohol use and/or promoting effective contraceptive use among risky drinkers who could become pregnant. The current study builds on promising findings about the impact of the Centers for Disease Control and Prevention CHOICES intervention with AI/AN communities by implementing a randomized control trial of Native CHOICES, a cultural adaptation of CHOICES, with AI/AN women in a rural reservation community. METHODS AI/AN women aged 18-44 who are at-risk for an alcohol-exposed pregnancy are being recruited. Participants are randomized in 1:1 proportion to the intervention and a services-as-usual, waitlist control condition. The Native CHOICES intervention consists of 2 motivational interviewing (MI) sessions, an elective contraception counseling session, and electronic messaging to boost the effects of MI. Data are collected at baseline and at 6 weeks, 3 months, and 6 months post-baseline. Those assigned to the control group are eligible to enroll in Native CHOICES following the completion of the 6 months post-baseline data collection. In addition to testing intervention effectiveness, the study is designed to yield a comprehensive economic evaluation, which will provide important information regarding the financial feasibility and sustainability of Native CHOICES for healthcare systems serving AI/ANs.

Cost-effectiveness analysis of public health interventions with impacts on health and criminal justice: An applied cross-sectoral analysis of an alcohol misuse intervention. HEALTH ECONOMICS 2021; 30:972-988. [PMID: 33604984 DOI: 10.1002/hec.4229] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 11/23/2020] [Accepted: 01/14/2021] [Indexed: 05/13/2023]
Abstract
Cost-effectiveness analyses of health care programs often focus on maximizing health and ignore nonhealth impacts. Assessing the cost-effectiveness of public health interventions from a narrow health care perspective would likely underestimate their full impact, and potentially lead to inefficient decisions about funding. The aim of this study is to provide a practical application of a recently proposed framework for the economic evaluation of public health interventions, evaluating an intervention to reduce alcohol misuse in criminal offenders. This cross-sectoral analysis distinguishes benefits and opportunity costs for different sectors, makes explicit the value judgments required to consider alternative perspectives, and can inform heterogeneous decision makers with different objectives in a transparent manner. Three interventions of increasing intensity are compared: client information leaflet, brief advice, and brief lifestyle counseling. Health outcomes are measured in quality-adjusted life-years and criminal justice outcomes in reconvictions. Costs considered include intervention costs, costs to the NHS and costs to the criminal justice system. The results are presented for four different perspectives: "narrow" health care perspective; criminal justice system perspective; "full" health care perspective; and joint "full" health and criminal justice perspective. Conclusions and recommendations differ according to the normative judgment on the appropriate perspective for the evaluation.

Abstract
AIMS To estimate US population health utilities for subgroups defined by alcohol use disorder (AUD) status and consumption level. DESIGN Cross-sectional survey. SETTING Community settings in the United States (i.e. excluding institutional settings). PARTICIPANTS A total of 36,042 adults (age 18+) in non-institutional settings in the United States. MEASUREMENTS We used 12-item Short Form Survey (SF-12) data from the National Epidemiologic Survey on Alcohol and Related Conditions-III to calculate mean Short Form-6 dimension (SF-6D) utility scores across World Health Organization alcohol consumption risk levels-very high risk, high risk, medium risk, low risk and an additional abstinent level-for three groups: (1) the general population (n = 36,042), (2) individuals with life-time AUD (n = 9925) and (3) individuals with current AUD (n = 5083), and assessed minimally important differences (MIDs) between consumption levels. Each group is a subset of the previous group. FINDINGS The general population's mean SF-6D utility was higher than that of individuals with life-time or current AUD across all consumption risk levels (0.79 versus 0.76 for both AUD groups). For all groups, SF-6D utilities increased as consumption risk level decreased to non-abstinent levels, and reducing consumption from very high risk to any lower level was associated with a statistically significant and meaningful improvement in utility. For individuals with life-time or current AUD, becoming abstinent from high-, medium- and low-risk levels was associated with significantly and meaningfully worse utilities. CONCLUSIONS Higher alcohol consumption risk levels appear to be associated with lower health index scores for the general population and individuals with a history of alcohol use disorder, meaning that higher alcohol consumption is associated with worse health-related quality of life.

The 'Outcome Reporting in Brief Intervention Trials: Alcohol' (ORBITAL) framework: protocol to determine a core outcome set for efficacy and effectiveness trials of alcohol screening and brief intervention. Trials 2017; 18:611. [PMID: 29273070 PMCID: PMC5741954 DOI: 10.1186/s13063-017-2335-3] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2017] [Accepted: 10/31/2017] [Indexed: 11/12/2022] Open
Abstract
Background The evidence base to assess the efficacy and effectiveness of alcohol brief interventions (ABI) is weakened by variation in the outcomes measured and by inconsistent reporting. The ‘Outcome Reporting in Brief Intervention Trials: Alcohol’ (ORBITAL) project aims to develop a core outcome set (COS) and reporting guidance for its use in future trials of ABI in a range of settings. Methods/design An international Special Interest Group was convened through INEBRIA (International Network on Brief Interventions for Alcohol and Other Drugs) to inform the development of a COS for trials of ABI. ORBITAL will incorporate a systematic review to map outcomes used in efficacy and effectiveness trials of ABI and their measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. This will support a multi-round Delphi study to prioritise outcomes. Delphi panellists will be drawn from a range of settings and stakeholder groups, and the Delphi study will also be used to determine if a single COS is relevant for all settings. A consensus meeting with key stakeholder representation will determine the final COS and associated guidance for its use in trials of ABI. Discussion ORBITAL will develop a COS for alcohol screening and brief intervention trials, with outcomes stratified into domains and guidance on outcome measurement instruments. The standardisation of ABI outcomes and their measurement will support the ongoing development of ABI studies and a systematic synthesis of emerging research findings. We will track the extent to which the COS delivers on this promise through an exploration of the use of the guidance in the decade following COS publication.

Abstract
Background The overarching goal of health policies is to maximize health and societal benefits. Economic evaluations can play a vital role in assessing whether or not such benefits occur. This paper reviews the application of modelling techniques in economic evaluations of drug and alcohol interventions with regard to (i) modelling paradigms themselves; (ii) perspectives of costs and benefits and (iii) time frame. Methods Papers that use modelling approaches for economic evaluations of drug and alcohol interventions were identified by carrying out searches of major databases. Results Thirty eight papers met the inclusion criteria. Overall, the cohort Markov models remain the most popular approach, followed by decision trees, Individual based model and System dynamics model (SD). Most of the papers adopted a long term time frame to reflect the long term costs and benefits of health interventions. However, it was fairly common among the reviewed papers to adopt a narrow perspective that only takes into account costs and benefits borne by the health care sector. Conclusions This review paper informs policy makers about the availability of modelling techniques that can be used to enhance the quality of economic evaluations for drug and alcohol treatment interventions.

Abstract
OBJECTIVE This study analyzed the cost-effectiveness of delivering alcohol screening, brief intervention, and referral to treatment (SBIRT) in emergency departments (ED) when compared to outpatient medical settings. METHODS A probabilistic decision analytic tree categorized patients into health states. Utility weights and social costs were assigned to each health state. Health outcome measures were the proportion of patients not drinking above threshold levels at follow-up, the proportion of patients transitioning from above threshold levels at baseline to abstinent or below threshold levels at follow-up, and the quality-adjusted life years (QALYs) gained. Expected costs under a provider perspective were the marginal costs of SBIRT, and under a societal perspective were the sum of SBIRT cost per patient and the change in social costs. Incremental cost-effectiveness ratios were computed. RESULTS When considering provider costs only, compared to outpatient, SBIRT in ED cost $8.63 less, generated 0.005 more QALYs per patient, and resulted in 13.8% more patients drinking below threshold levels. Sensitivity analyses in which patients were assumed to receive a fixed number of treatment sessions that met clinical sites' guidelines made SBIRT more expensive in ED than outpatient; the ED remained more effective. In this sensitivity analysis, the ED was the most cost-effective setting if decision makers were willing to pay more than $1500 per QALY gained. CONCLUSIONS Alcohol SBIRT generates costs savings and improves health in both ED and outpatient settings. EDs provide better effectiveness at a lower cost and greater social cost reductions than outpatient.

Abstract
PURPOSE To investigate the ability of the EQ-5D to discriminate between levels of alcohol risk in a large sample of hazardous and harmful drinkers, and to explore the relationship between transitions between alcohol risk levels and changes in EQ-5D up to 12 months. METHODS This is a web-based randomised controlled trial evaluating a novel intervention for hazardous and harmful alcohol consumption. EQ-5D scores were compared among groups of drinkers at baseline (low/medium/high risk according to self-reported past week alcohol consumption), and changes in EQ-5D scores were estimated as a function of changes in alcohol consumption level. RESULTS Baseline EQ-5D scores were dominated by problems with anxiety/depression, which increased with alcohol risk level, whilst high-risk drinkers also experienced more problems with physical HRQoL dimensions. However, the tool demonstrated a considerable ceiling effect. At follow-up, despite considerable reductions in alcohol consumption across the sample, significant changes in aggregated EQ-5D index scores were only observed for high-risk drinkers at baseline who reduced their drinking, with small improvements (0.04-0.06) compared to those who did not reduce. CONCLUSIONS Our results suggest that the three-option EQ-5D may not be an optimal primary end point for measuring clinical and cost-effectiveness in randomised controlled trials of interventions among hazardous and harmful alcohol users, although further testing of the sensitivity of the tool in these populations is needed.

Abstract
BACKGROUND Studies indicate that community pharmacy-based alcohol brief intervention (BI) is feasible. However, few studies report significant reductions in post-BI alcohol consumption and customer experience. Cost-effectiveness has not been previously examined. OBJECTIVES This 5 month study adopted a single group pre- and post-experimental design to: (1) assess uptake of the community pharmacy alcohol BI service; (2) establish post-BI changes in alcohol consumption for hazardous drinkers; (3) report the acceptability of the service to customers who received it; and (4) undertake a preliminary economic evaluation of the service through establishing whether pharmacy-based alcohol BI affected health and social care costs, including lost employment costs, and whether it was cost-effective. SETTING 26 community pharmacies in south London, UK. METHOD Trained pharmacists used the AUDIT-C and a retrospective 7-day Drinking Diary to identify risky drinkers and inform feedback and advice. Harmful drinkers were referred to their general practitioner and/or specialist alcohol services. A confidential service feedback questionnaire was completed by alcohol BI recipients. Baseline and 3-month follow-up telephone interviews were conducted with hazardous and low risk drinkers to assess post-BI alcohol use change and service cost-effectiveness. MAIN OUTCOME MEASURES AUDIT-C, 7-day alcohol unit consumption, drinking days, cost utilisation data. RESULTS Of the 663 eligible customers offered alcohol BI, 141 (21 %) took up the service. Three-quarters of customers were identified as risky drinkers. Follow-up interviews were conducted with 61 hazardous/low risk drinkers (response rate = 58 %). Hazardous drinkers were found to significantly reduce their 7-day alcohol unit consumption and drinking days, but not AUDIT-C scores. The majority of harmful drinkers (91 %, n = 10) who were contactable post-BI had accessed further alcohol related services. Customer feedback was generally positive. Over 75 % of customers would recommend the service to others. The cost of delivering the service was estimated to be £ 134. The difference in service costs pre-BI and post-BI was not statistically significant and remained non-significant when calculated on 500 customers receiving the intervention. CONCLUSION Community pharmacy-based alcohol BI is a low cost service that may not have immediate beneficial impact on health and social service use, but can be effective in reducing drinking in hazardous drinkers.

Abstract
Objective Alcohol dependence is a common condition associated with high direct and indirect health care costs. The purpose of this analysis was to estimate the economic consequences of acamprosate used as adjuvant therapy in the treatment of alcoholism, defining a budget impact analysis (BIA) from the point of view of the Italian National Health Service (NHS). Methods We developed a model of disease evolution related to alcoholism using data from the PRAMA study. The hypothetical population included in the decision model was obtained from data from the Ministry of Health. We compared the following treatment strategies: no treatment, standard care (psychotherapy), sodium oxybate (sodium salt-4-hydroxybutyric acid), and acamprosate. The time horizon of the model was 10 years. The costs were evaluated from the NHS perspective. Results We simulated the path for 69,348 patients treated at the outpatient clinics of the Addiction Services (SerT), and 38,911 patients discharged from hospital. Patients in the acamprosate group had lower alcohol-related events, with a reduction of the total cost. The BIA shows that the increase in the use of acamprosate was associated with a progressive decrease of total costs, calculated as the sum of the diagnosis-related groups (DRG), rehabilitation, and drug costs. The increasing use of acamprosate instead of standard care and sodium oxybate would generate cost savings up to over €6 million over 10 years of simulation. Conclusion The estimates in the model are based on hypothetical situations; the assumptions of the model as well as their specific impact on treatment effect estimations and clinical implications should be validated in real life. Public health care authorities would benefit from mathematical models designed to estimate the future burden of alcohol dependence together with the impact of treatment and the potential to reduce the incidence and progression of this condition, and the costs of its complications.

Abstract
OBJECTIVE This study evaluated the costs and cost-effectiveness of combining motivational interviewing with feedback to address heavy drinking among university freshmen. METHOD Microcosting methods were used in a prospective cost and cost-effectiveness study of a randomized trial of assessment only (AO), motivational interviewing (MI), feedback only (FB), and motivational interviewing with feedback (MIFB) at a large public university in the southeastern United States. Students were recruited and screened into the study during freshman classes based on recent heavy drinking. A total of 727 students (60% female) were randomized, and 656 had sufficient data at 3-months' follow-up to be included in the cost-effectiveness analysis. Effectiveness outcomes were changes in average drinks per drinking occasion and number of heavy drinking occasions. RESULTS Mean intervention costs per student were $16.51 for MI, $17.33 for FB, and $36.03 for MIFB. Cost-effectiveness analysis showed two cost-effective interventions for both outcomes: AO ($0 per student) and MIFB ($36 per student). CONCLUSIONS This is the first prospective cost-effectiveness study to our knowledge to examine MI for heavy drinking among students in a university setting. Despite being the most expensive intervention, MIFB was the most effective intervention and may be a cost-effective intervention, depending on a university's willingness to pay for changes in the considered outcomes.

Abstract
BACKGROUND To assess existing health economic strategies, which are used to evaluate the economic value of drugs to treat alcohol dependence (AD) such as acamprosate, naltrexone and any other pharmaceuticals. METHODS A systematic literature search on AD treatment economic evaluation studies was performed in multiple electronic bibliographic and economic databases. RESULTS A total of seven studies were found that involved economic evaluations of pharmacotherapy treatment of AD. It was seen that all individual pharmacotherapy treatment programs including acamprosate, naltrexone and combined treatments have resulted in a net benefit or cost savings. However, the examined studies used different methods to estimate the costs, cost savings, and cost effectiveness of the treatments. CONCLUSIONS Pharmacotherapy treatment of AD produced marked economic benefits. However, the number of studies on the economic evaluation of pharmacotherapy for AD treatment is limited. The gaps in these studies have also been identified as necessitating more research.

Abstract
BACKGROUND Alcohol abuse results in problems on various levels in society. In terms of health, alcohol abuse is not only an important risk factor for chronic disease, but it is also related to injuries. Social harms which can be related to drinking include interpersonal problems, work problems, violent and other crimes. The scope of societal costs related to alcohol abuse in principle should be the same for both economic evaluations and cost-of-illness studies. In general, economic evaluations report a small part of all societal costs. To determine the cost- effectiveness of an intervention it is necessary that all costs and benefits are included. The purpose of this study is to describe and quantify the difference in societal costs incorporated in economic evaluations and cost-of-illness studies on alcohol abuse. METHOD To investigate the economic costs attributable to alcohol in cost-of-illness studies we used the results of a recent systematic review (June 2009). We performed a PubMed search to identify economic evaluations on alcohol interventions. Only economic evaluations in which two or more interventions were compared from a societal perspective were included. The proportion of health care costs and the proportion of societal costs were estimated in both type of studies. RESULTS The proportion of healthcare costs in cost-of-illness studies was 17% and the proportion of societal costs 83%. In economic evaluations, the proportion of healthcare costs was 57%, and the proportion of societal costs was 43%. CONCLUSIONS The costs included in economic evaluations performed from a societal perspective do not correspond with those included in cost-of-illness studies. Economic evaluations on alcohol abuse underreport true societal cost of alcohol abuse. When considering implementation of alcohol abuse interventions, policy makers should take into account that economic evaluations from the societal perspective might underestimate the total effects and costs of interventions.
