DATStats: results from 85 studies using the Drug Abuse Treatment Cost Analysis Program.

The Drug Abuse Treatment Cost Analysis Program (DATCAP) was developed and launched in the early 1990s to help addiction researchers and administrators estimate the economic costs of substance abuse interventions. This paper presents summary results from 85 DATCAPs completed over the past 10 years. After first grouping the DATCAPs into 9 treatment modalities, cost measures (normalized to 2001 dollars) are reported along with client caseload information. Additionally, the distribution of costs across 6 resource categories is presented for each of the treatment modalities. The average weekly economic cost per client ranged from 82 US dollars per week for outpatient drug court interventions to 1,138 US dollars per week for adolescent residential treatment. As expected, labor was overwhelmingly the most utilized resource across all modalities, ranging from 48% to 88% of total economic cost. Addiction researchers, program administrators, and policymakers now have cost estimates and resource distribution information for various treatment modalities serving diverse populations.

Dangerous to your health: the role of chronic drug use in serious injuries and trauma.

OBJECTIVES: This study estimated the differential risks of serious injury or trauma for a community-based sample of chronic drug users (CDUs; n = 926) and a matched group of nondrug users (NDUs; n = 553). The study also estimated whether CDUs and NDUs differed in their utilization of health care services for serious injury or trauma. MATERIALS AND METHODS: Data were collected in 1996 and 1997 through community outreach activities in Miami-Dade County, Florida. The analysis estimated the effects of drug use on (1) any lifetime serious injury or trauma, (2) any serious injury or trauma during the past 12 months, and (3) utilization of health care services for serious injury or trauma. All analyses were gender specific and the models were also estimated with a measure of problematic alcohol use in addition to CDU. To examine the potential endogeneity of drug use, various specification tests were conducted. RESULTS: For females, CDUs experienced significantly more serious injury, trauma, or both (both lifetime and past year) than nonusers. Drug use status was not a significant predictor of serious injury or trauma (lifetime and past year) for males. Regardless of gender, conditional on experiencing any serious injury or trauma during the past year, CDUs and NDUs did not differ in their utilization of health care services. Various statistical tests determined that CDU was exogenous in all specifications and the findings were largely unchanged when problematic alcohol use was included in the models. CONCLUSIONS: The elevated risk for serious injury or trauma for female CDUs renders these persons vulnerable to severe medical problems. Specific training in substance abuse issues may be necessary if health care providers are to identify, engage, knowledgeably serve, and refer CDUs for appropriate services.

The relative contribution of outcome domains in the total economic benefit of addiction interventions: a review of first findings.

AIMS: This paper provides a focused summary of the relative contribution of addiction intervention outcomes to total economic benefit, based upon a compilation of published economic studies from the United States. DESIGN: The relevant literature was searched extensively, and 11 economic studies were selected for review. SETTING: The selected addiction interventions address both alcohol use/abuse and illicit drug use/abuse and represent various treatment modalities, including a brief physician intervention and long-term residential programs. PARTICIPANTS: Study participants included community-based drug users, pregnant and/or parenting women, problem drinkers, and criminal offenders. MEASUREMENTS: These studies estimated the economic benefits of an addiction intervention(s) in terms of one or more of the following outcome domains: criminal activity, health services utilization, employment earnings, and expenditures on illicit drugs and alcohol. FINDINGS: The primary finding of this review was that avoided criminal activity was the greatest economic benefit of addiction interventions and contributed more, as a separate outcome domain, to the total economic benefit of addiction interventions than any other outcome domain. Reduced utilization of health care services was also a noteworthy economic benefit of addiction interventions. CONCLUSIONS: This study provides a detailed exposition of economic benefits estimation and highlights the potential impact of individual outcomes, thus providing a useful resource for substance abuse researchers and administrators as they design and evaluate future interventions.

Outpatient marijuana treatment for adolescents. Economic evaluation of a multisite field experiment.

An economic evaluation of five outpatient adolescent treatment approaches (12 total site-by-conditions) was conducted. The economic cost of each of the 12 site-specific treatment conditions was determined by the Drug Abuse Treatment Cost Analysis Program (DATCAP). Economic benefits of treatment were estimated by first monetizing a series of treatment outcomes and then analyzing the magnitude of these monetized outcomes from baseline through the 12-month follow-up. The average economic costs ranged from $90 to $313 per week and from $839 to $3,279 per episode. Relative to the quarter before intake, the average quarterly cost to society for the next 12 months (including treatment costs) significantly declined in 4 of the 12 site-by-treatment conditions, remained unchanged in 6 conditions, and increased in 2 treatment conditions (both in the same site). These results suggest that some types of substance-abuse intervention for adolescents can reduce social costs immediately after treatment.

Using the DATCAP and ASI to estimate the costs and benefits of residential addiction treatment in the State of Washington.

Funding agencies and policy makers often criticize residential addiction treatment because the cost of residential services is typically higher than for outpatient services and it is unclear whether the outcomes are significantly better for most clients. To address these concerns, proponents of residential treatment require economic evidence to justify further investments in this modality over less intensive and less costly options. Recent studies have developed methods and empirical guidelines for using the drug abuse treatment cost analysis program (DATCAP) and the addiction severity index (ASI) in a comprehensive economic evaluation of addiction treatment. The present study applied these methods and guidelines to estimate the economic costs and benefits of residential addiction treatment at five programs in the State of Washington, USA that serve publicly funded clients. Program- and client-specific economic cost estimates were derived using data collected on-site with the DATCAP along with opportunity cost estimates associated with treatment attendance. Economic benefits were calculated from client self-reported information at treatment entry and at 6 months post discharge using the ASI. Outcome categories included inpatient services, employment, medical and psychiatric conditions, and criminal activity. Results indicate that average weekly economic cost of treatment services at the five programs ranged from 463 dollars to 703 dollars. Average (per client) economic cost of treatment was 4912 dollars (composed of 3650 dollars in program cost and 1262 dollars in client cost) for all subjects that completed both a baseline and follow-up questionnaire (N = 222; 82%). Average (per client) total economic benefit was 21,329 dollars, leading to estimates of 16,418 dollars for average net benefit and 4.34 for the benefit-cost ratio. Total and net economic benefits were significantly related to gender, race, religious preference, and baseline ASI composite scores for drug use and legal status. A detailed sensitivity analysis did not alter the qualitative findings. This study provides conclusive evidence that, for this sample of programs in Washington State, the economic benefits of residential addiction treatment significantly exceeded the economic costs. Although the results are not necessarily generalizable to private-paying clients or clients from other States in the US, the methods are based on widely used data collection instruments and well-accepted economic principles. Thus, extensions of this research to other clients, States, and modalities should be feasible and straightforward.

The economic cost of outpatient marijuana treatment for adolescents: findings from a multi-site field experiment.

AIMS: Despite recent advances in the economic evaluation of adult substance abuse treatment, information and basic research is lacking on the cost of adolescent substance abuse treatment. The present study conducted an economic cost analysis of several outpatient adolescent treatment approaches. DESIGN: The Cannabis Youth Treatment (CYT) study evaluated five structured treatments for cannabis-using adolescents. One of the approaches was implemented by all of the four geographically and institutionally diverse treatment facilities collaborating in CYT; each of the other four approaches was implemented in two of the sites. Using the Drug Abuse Treatment Cost Analysis Program (DATCAP), the economic cost of each site-specific treatment was determined. FINDINGS: The average economic costs of the five types of outpatient treatments ranged from $837 to $3334 per episode, and varied by both direct factors (e.g. hours of treatment, treatment retention) and indirect factors (e.g. cost of living, staff level, case-load variation). CONCLUSIONS: These adolescent treatment cost estimates are examined in terms of their calculation, variability by condition, variability by site within condition and comparability with previous DATCAP results from outpatient drug-free programs for adults. Future research will integrate treatment outcomes and costs to complete cost-effectiveness and benefit-cost analyses of the five therapies.

Benefit-cost analysis of addiction treatment in Arkansas: specialty and standard residential programs for pregnant and parenting women.

A benefit-cost analysis of specialty residential treatment (Specialty) and standard residential treatment (Standard) was conducted on a sample of pregnant and parenting substance abusers from Arkansas. Economic benefits were derived from client self-reported information at treatment entry and at 6-month postdischarge with the use of an augmented version of the Addiction Severity Index (ASI). The average cost of treatment in Specialty programs was US dollars 8035 versus US dollars 1467 for Standard residential treatment. Average net benefits (benefit-cost ratios) were estimated to be US dollars 17144 (3.1) for Specialty and US dollars 8090 (6.5) for Standard. The main policy implication of this research is that investment in Specialty residential treatment for pregnant and parenting substance-abusing women appears to be economically justified, but future evaluations should analyze larger and more comparable samples to improve power and precision in the benefit-cost statistics.

Benefit-cost analysis of addiction treatment: methodological guidelines and empirical application using the DATCAP and ASI.

OBJECTIVE: To provide detailed methodological guidelines for using the Drug Abuse Treatment Cost Analysis Program (DATCAP) and Addiction Severity Index (ASI) in a benefit-cost analysis of addiction treatment. DATA SOURCES/STUDY SETTING: A representative benefit-cost analysis of three outpatient programs was conducted to demonstrate the feasibility and value of the methodological guidelines. STUDY DESIGN: Procedures are outlined for using resource use and cost data collected with the DATCAP. Techniques are described for converting outcome measures from the ASI to economic (dollar) benefits of treatment. Finally, principles are advanced for conducting a benefit-cost analysis and a sensitivity analysis of the estimates. DATA COLLECTION/EXTRACTION METHODS: The DATCAP was administered at three outpatient drug-free programs in Philadelphia, PA, for 2 consecutive fiscal years (1996 and 1997). The ASI was administered to a sample of 178 treatment clients at treatment entry and at 7-months postadmission. PRINCIPAL FINDINGS: The DATCAP and ASI appear to have significant potential for contributing to an economic evaluation of addiction treatment. The benefit-cost analysis and subsequent sensitivity analysis all showed that total economic benefit was greater than total economic cost at the three outpatient programs, but this representative application is meant to stimulate future economic research rather than justifying treatment per se. CONCLUSIONS: This study used previously validated, research-proven instruments and methods to perform a practical benefit-cost analysis of real-world treatment programs. The study demonstrates one way to combine economic and clinical data and offers a methodological foundation for future economic evaluations of addiction treatment.

Brief physician advice for problem drinkers: long-term efficacy and benefit-cost analysis.

BACKGROUND: This report describes the 48-month efficacy and benefit-cost analysis of Project TrEAT (Trial for Early Alcohol Treatment), a randomized controlled trial of brief physician advice for the treatment of problem drinking. METHODS: Four hundred eighty-two men and 292 women, ages 18-65, were randomly assigned to a control (n = 382) or intervention (n = 392) group. The intervention consisted of two physician visits and two nurse follow-up phone calls. Intervention components included a review of normative drinking, patient-specific alcohol effects, a worksheet on drinking cues, drinking diary cards, and a drinking agreement in the form of a prescription. RESULTS: Subjects in the treatment group exhibited significant reductions (p < 0.01) in 7-day alcohol use, number of binge drinking episodes, and frequency of excessive drinking as compared with the control group. The effect occurred within 6 months of the intervention and was maintained over the 48-month follow-up period. The treatment sample also experienced fewer days of hospitalization (p = 0.05) and fewer emergency department visits (p = 0.08). Seven deaths occurred in the control group and three in the treatment group. The benefit-cost analysis suggests a 43,000 dollars reduction in future health care costs for every 10,000 dollars invested in early intervention. The benefit-cost ratio increases when including the societal benefits of fewer motor vehicle events and crimes. CONCLUSIONS: The long-term follow-up of Project TrEAT provides the first direct evidence that brief physician advice is associated with sustained reductions in alcohol use, health care utilization, motor vehicle events, and associated costs. The report suggests that a patient's personal physician can successfully treat alcohol problems and endorses the implementation of alcohol screening and brief intervention in the US health care system.

Decision latitude and workload demand: implications for full and partial absenteeism.

This research examined the relative importance of two components of job stress--decision latitude and workload demand--on employee absenteeism. The analysis was based on confidential self-reported data from employees at two worksites, which were collected in three independent cross-sections beginning in 1995. The negative binomial technique was used to estimate the effects of decision latitude and workload demand on employee attendance, while controlling for employee demographics and other workplace characteristics. Estimation results show that high decision latitude was negatively and significantly related to number of full days absent from work (full absenteeism) and number of days arriving late to work or leaving work early (partial absenteeism). Conversely, the coefficient estimates for low decision latitude were positive in every model and significantly related to partial absenteeism. Low workload demand was negatively and significantly related to partial absenteeism, but not full days absent. The interaction effects of decision latitude and workload demand on absenteeism were not statistically significant. Several recent studies have estimated a significant relationship between decision latitude, workload demand, and medical problems such as cardiovascular disease. The current findings suggest that decision latitude and workload demand are also related to workplace attendance. Employers and occupational hygienists should consider decision latitude and workload demand as a means to improve workplace productivity and employee health.

Alcohol consumption, risk of injury, and high-cost medical care.

This study examined the effect of alcohol use on the probabilities of injury, inpatient hospital stay, and emergency department visit. Data were obtained from a sample of adults (N = 1219) recruited from a Northern California county. Alcohol use measures included number of drinks, heavy drinking days, and an indicator variable for problem drinking. Models were estimated for men and women separately while controlling for confounders. Results indicate that most alcohol use measures were not significantly related to injury probability or medical care utilization. Among the exceptions, problem drinking was a significant positive predictor of any emergency department visit for both sexes. When drinkers during the past year were divided into light, moderate, and heavy drinking groups and compared to lifetime abstainers, all male drinkers had a higher probability of injury, and light and moderate female drinkers had a lower probability of an emergency department visit.
