The relationship of antidepressant prescribing concentration to treatment duration and cost.

BACKGROUND: Widely accepted treatment guidelines and performance measures encourage patients to stay on antidepressant medication beyond the acute phase of treatment in order to achieve full remission and reduce risk of relapse. However, many patients discontinue antidepressant medication treatment prematurely for various reasons, including side-effects or nonresponse to the initial medication prescribed. Customization of medications to differing patient profiles could potentially improve medication treatment duration, but for many diseases physicians tend to concentrate on a limited subset of available medications. Little is known about the effects of concentration in prescribing on medication treatment duration and expenditures. AIMS OF THE STUDY: To determine the extent to which prescribing for treatment of depression is concentrated, using data from a privately insured population. To evaluate the relationship between prescribing concentration and subsequent duration of medication treatment, expenditure on medications, and the number of distinct medications used. STUDY POPULATION: Individuals receiving antidepressant treatment paid for by a large private managed behavioral health organization, in the US. METHODS: The study uses psychotropic pharmacy claims data for 2003-06 for plan members who received a depression diagnosis and had an antidepressant claim. The resulting sample includes 9,017 patients seen by 543 prescribers. For each prescriber, we compute prescribing concentration, using the Herfindahl index and the share for the three most-used medications. Treatment expenditure is computed as the sum of payments by plan and by patients. Regression analysis is used to identify the association of prescribing concentration with medication treatment duration, expenditures and other utilization measures. RESULTS: For these physicians, the mean share of the physician's total antidepressant prescribing accounted for by their three most-used regimens was 72%. The mean value of the Herfindahl index was 0.27. Over the 180-day follow-up period, the average patient had 103 days covered by antidepressant prescriptions, resulting in mean expenditures of $286, or $2.25 per day of medication supplied. Regression analysis indicates that higher concentration in a physician's prescribing was associated with fewer days of antidepressant coverage, lower medication expenditures, and subsequent use of fewer distinct medications. DISCUSSION: Higher concentration in prescribing is associated with shorter observed duration of medication treatment and lower expenditures on medications. The lower expenditures appear to be due to earlier discontinuation and fewer different medications, not to a lower cost per day supplied. Limitations of this study include lack of data on medical visits or on reasons for medication discontinuation, as the study is based on pharmacy claims data, not medical claims or surveys. In addition, it is not known whether the patient's antidepressant use represents a new episode. Finally, lack of randomization implies that the associations identified may not be causal. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: Concentration of physicians on certain medications may run counter to the increasing calls for customization of medication selection. IMPLICATIONS FOR HEALTH POLICY: Insurer policies which limit physicians' choice of medications may be lowering expenditures in part by reducing patients' medication treatment duration. IMPLICATIONS FOR FURTHER RESEARCH: Additional studies are needed to understand what mechanisms may link concentration in prescribing to medication treatment duration and expenditures.

Substance abuse treatment client experience in an employed population: results of a client survey.

BACKGROUND: Understanding client perspectives on treatment is increasingly recognized as key to improving care. Yet information on the perceptions and experiences of workers with private insurance coverage who receive help for substance use conditions is relatively sparse, particularly in managed behavioral health care organization (MBHO) populations. Furthermore, the role of several factors including prior service use has not been fully explored. METHODS: Employees covered by a large MBHO who had received substance abuse services in the past year were surveyed (146 respondents completed the telephone survey and self-reported service use). RESULTS: The most common reasons for entering treatment were problems with health; home, family or friends; or work. Prior treatment users reported more reasons for entering treatment and more substance use-related work impairment. The majority of all respondents felt treatment helped a lot or some. One quarter reported getting less treatment than they felt they needed. DISCUSSION AND CONCLUSIONS: Study findings point to the need to tailor treatment for prior service users and to recognize the role of work in treatment entry and outcomes. Perceived access issues may be present even among insured clients already in treatment.

EAP Service Use in a Managed Behavioral Health Care Organization: From the Employee Perspective.

Contemporary employee assistance program (EAP) services are typically provided in broad-brush programs delivered by large external vendors in a network model. Yet research has not kept pace with EAP evolution, including in terms of how EAP clients themselves view services. We surveyed a random sample of EAP service users from a national provider (361 respondents). About one-third of respondents reported getting help for workplace issues. Most learned about the EAP through employer communications such as the company website. The large majority reported that the EAP helped them "a lot" or "some," suggesting they valued this benefit.

Integrated employee assistance program/managed behavioral health plan utilization by persons with substance use disorders.

New federal parity and health reform legislation, promising increased behavioral health care access and a focus on prevention, has heightened interest in employee assistance programs (EAPs). This study investigated service utilization by persons with a primary substance use disorder (SUD) diagnosis in a managed behavioral health care (MBHC) organization's integrated EAP/MBHC product (N = 1,158). In 2004, 25.0% of clients used the EAP first for new treatment episodes. After initial EAP utilization, 44.4% received no additional formal services through the plan, and 40.4% received regular outpatient services. Overall, outpatient care, intensive outpatient/day treatment, and inpatient/residential detoxification were most common. About half of the clients had co-occurring psychiatric diagnoses. Mental health service utilization was extensive. Findings suggest that for service users with primary SUD diagnoses in an integrated EAP/MBHC product, the EAP benefit plays a key role at the front end of treatment and is often only one component of treatment episodes.

Patterns of service use in two types of managed behavioral health care plans.

OBJECTIVE: The study examined service use patterns by level of care in two managed care plans offered by a national managed behavioral health care organization (MBHO): an employee assistance program (EAP) combined with a standard behavioral health plan (integrated plan) and a standard behavioral health plan. METHODS: The cross-sectional analysis used 2004 administrative data from the MBHO. Utilization of 11 specific service categories was compared. The weighted sample reflected exact matching on sociodemographic characteristics (unweighted N=710,014; weighted N=286,750). RESULTS: A larger proportion of enrollees in the integrated plan than in the standard plan used outpatient mental health and substance abuse office visits (including EAP visits) (p<.01) and substance abuse intensive outpatient or day treatment (p<.05), and the proportion using residential substance abuse rehabilitation was lower (p<.05). CONCLUSIONS: The integrated and standard products had distinct utilization patterns in this large MBHO. In particular, greater use of certain outpatient services was observed in the integrated plan.

The effect of employee assistance plan benefits on the use of outpatient behavioral health care.

BACKGROUND: Nearly half of all US workers have access to an employee assistance plan (EAP). At the same time, most large US employers also purchase health benefits for their employees, and these benefits packages typically include behavioral health services. There is some potential overlap in services covered by the EAP and the health plan, and some employers choose to purchase the two jointly as an 'integrated product'. It is not clear whether EAP services substitute for outpatient behavioral health care services covered by the health plan. AIM OF THE STUDY: To evaluate how the number of EAP visits covered affects the use of regular outpatient behavioral health care (number of visits, and total spending), in an integrated product setting. METHODS: Analysis of claims, eligibility and benefits data for 26,464 users of behavioral health care for the year 2005. For both EAP and regular behavioral health care, the individuals were enrolled with Managed Health Network (MHN), a large national specialty insurance plan. Multivariate regression analyses were performed to investigate the determinants of the number of regular outpatient visits, and spending for regular outpatient care. To address skewness in the dependent variables, the estimation used generalized linear models with a log link. A limited instrumental variable analysis was used to test for endogeneity of the number of EAP visits covered. RESULTS: Nearly half the enrollees in this sample were in employer plans that allowed 4-5 EAP visits per treatment episode, and 31% were allowed 3 EAP visits per year. Having an EAP visit allowance of 4-5 sessions per episode predicts fewer regular outpatient visits, compared with having an allowance of 3 sessions per year. More generous EAP allowances also reduce payments for outpatient care, with one exception. DISCUSSION: Greater availability of EAP benefits appears to reduce utilization of regular outpatient care, supporting the idea that the two types of care are to some extent perceived as substitutes. One limitation of this study is its cross-sectional nature, since the relationships observed could reflect the effect of other unmeasured variables. Also, the data are from a single managed behavioral health organization, limiting generalizability somewhat, although many employers are represented in the data. IMPLICATIONS FOR HEALTH POLICY: The results should discourage employers from either eliminating EAP benefits as duplicative, or replacing behavioral health benefits with an expanded EAP. Patients appear to perceive that EAP services offer something distinct from regular outpatient care. IMPLICATIONS FOR FURTHER RESEARCH: Future studies should see whether these results are reproduced, ideally by looking at employer plans with a wider range of EAP visit allowances.

EMPLOYER CHOICES IN EAP DESIGN AND WORKSITE SERVICES.

In today's complex private healthcare market, employers have varied preferences for particular features of behavioral health products such as Employee Assistance Programs (EAPs). Factors which may influence these preferences include: establishment size, type of organization, industry, workplace substance abuse regulations, and structure of health insurance benefits. This study of 103 large employer purchasers from a single managed behavioral healthcare organization investigated the impact of such variables on the EAP features that employers select to provide to workers and their families. Our findings indicate that for this group of employers, preferences for the type and delivery mode of EAP counseling services are fairly universal, while number of sessions provided and choices for EAP-provided worksite activities are much more varied, and may be more reflective of the diverse characteristics, organizational missions and workplace culture found among larger employers in the US.

Integrated employee assistance program/managed behavioral health care benefits: relationship with access and client characteristics.

This study examined service user characteristics and determinants of access for enrollees in integrated EAP/behavioral health versus standard managed behavioral health care plans. A national managed behavioral health care organization's claims data from 2004 were used. Integrated plan service users were more likely to be employees rather than dependents, and to be diagnosed with adjustment disorder. Logistic regression analyses found greater likelihood in integrated plans of accessing behavioral health services (OR 1.20, CI 1.17-1.24), and substance abuse services specifically (OR 1.23, CI 1.06-1.43). Results are consistent with the concept that EAP benefits may increase access and address problems earlier.

Workplace Stress, Organizational Factors and EAP Utilization.

This study examined relationships between workplace stress, organizational factors and use of EAP counseling services delivered by network providers in a large, privately-insured population. Claims data were linked to measures of workplace stress, focus on wellness/prevention, EAP promotion, and EAP activities for health care plan enrollees from 26 employers. The association of external environment and work organization variables with use of EAP counseling services was examined. Higher levels of EAP promotion and worksite activities were associated with greater likelihood of service use. Greater focus on wellness/prevention and unusual and significant stress were associated with lower likelihood of service use. Results provide stakeholders with insights on approaches to increasing utilization of EAP services.
