Health care utilization of families of carpenters with alcohol or substance abuse-related diagnoses

BACKGROUND: Patterns of health care utilization of families of carpenters with and without alcohol and/or substance abuse related diagnoses (ASRD) were compared. METHODS: Utilization data for families of 13,657 carpenters for a 10 year period were analyzed. Concordance of diagnoses among family members was assessed and proportionate utilization ratios were used to compare the experiences of families of carpenters with and without ASRD. RESULTS: Twenty-eight percent of the spouses with ASRD had a carpenter spouse with a similar diagnosis. Twenty-four percent of the families with a child with ASRD had a parent with one of these diagnoses compared to 9.4% of families without any children with ASRD (P < 0.0001). Families of carpenters with alcohol or ASRD also had different patterns of health care utilization. CONCLUSIONS: Utilization patterns were influenced to a significant degree by concordant diagnoses among spouses and children. Excess mental health care was seen among families of carpenters with ASRD above their care for substance abuse treatment.     

Work-related eye injuries among union carpenters

Union administrative records were combined with workers' compensation data to identify a cohort of 12,958 active union carpenters, their person-time at risk, and their documented work-related eye injuries between 1989 and 1995 in the state of Washington. The injuries were described using ANSI codes for injury nature, type (mechanism), and source or object associated with the event. Injuries which resulted in paid lost time from work were also described based on the ICD-9 codes attached to claims for their medical treatment. Overall rates of filing compensation claims for eye injuries as well as age, gender, and union local specific rates were calculated. To identify high risk subgroups and explore incident and recurrent events, the person-time and events were stratified by age, gender, time in the union, claim status, and predominant type of work of the union local with which each carpenter was affiliated for multivariate analyses with Poisson regression. Eye injuries were responsible for 12 percent (n = 1730) of workers' compensation claims during this time period, exceeded only by back and finger injuries. Thirty-one claims resulted in paid lost time from work and these cases accounted for one-third of all costs for medical care for eye injuries. At least 10 percent of all medical costs for eye injuries and 35.5 percent of medical costs for eye injuries which resulted in paid lost time were associated with injuries sustained while hammering--a very common carpenter exposure. Claims were filed at an estimated rate of 6.1 per 200,000 hours worked. Individuals with previous compensation claims for eye injuries had rates of injury 1.6 times higher than individuals without previous eye injuries. Rates decreased significantly with age and time in the union. Eye injuries among these union carpenters were very common, but the rate of injuries severe enough to require paid time off work was quite low. These findings raise questions about factors which might influence the failure to use appropriate protection including availability and acceptability of eye protection, use by peers, and perception of risk.     

Falls among union carpenters

BACKGROUND: Falls are a leading cause of morbidity and mortality in the construction trades. METHODS: We identified a cohort of 16,215 active union carpenters, hours worked, and their workers' compensation claims for a 10-year period. The data on this well-defined cohort were used to describe their work-related falls; to define rates of injury and the associated costs; and to identify high-risk groups. RESULTS: Same level falls occurred at a rate of 1.8/200,000 hours worked; falls from elevations at a rate of 2.3/200,000 hours worked. These injuries resulted in direct payments of 0.30 dollars per hour of work or 2.40 dollars per 8-hr day. Mean costs per fall increased with increasing age. Age was not associated with risk of falls from elevations; younger carpenters had modestly reduced rates of falls from the same level. Rates of falls decreased with increasing time in the union. Carpenters whose usual work involved drywall installation or residential work were at highest risk. CONCLUSIONS: Falls are a significant public health risk for carpenters and they are responsible for a significant burden of work-related injury costs. While there is a need for prevention of falls from elevations--through training, enforcement of fall protection regulations, improved safety climate, or engineering changes--there is also the need to prevent falls from lower elevations. Differences in risk likely reflect varying exposures and safety practices in different areas of carpentry, as well as training, experience, and job assignments based on longevity in the union.     

Work-related injuries in drywall installation

Administrative data sources were used to describe the work-related injuries of drywall carpenters, to calculate rates of occurrence, and to explore high risk sub-groups. Health insurance eligibility files were used to identify a cohort of active union carpenters affiliated with a union local whose predominant work involved drywall installation in the state of Washington. These files contained the hours worked by each individual for each month between January 1989 and December 1995, providing person-hours at risk as a union carpenter. The Washington Department of Labor and Industries (L&I) provided records of workers' compensation claims filed by these individuals. Over seven years 1773 drywall carpenters filed 2567 workers' compensation claims representing an overall rate of 53.3 per 200,000 hours worked. These claims were filed by 1046 different individuals, or 59.0 percent of the cohort. Claims resulting in paid lost time from work were filed at a rate of 12.5 per 200,000 hours worked (n = 609) by 445 (25.1%) different individuals. The most common mechanisms of injury involved being struck (38.3%), overexertion (28.1%), and falls (13.2%). Struck by injuries most commonly involved cuts to the upper extremity. Overexertion injuries were most commonly described as sprains or strains involving the back. Sheetrock was associated with over 40 percent of these injuries. Falls most commonly involved injuries to the knee followed by the back and multiple injuries. Struck by injuries decreased steadily with increasing age and increasing time in the union. There was a steady increase in the rate of falls with increasing age. Overexertion injuries were responsible for the greatest proportion of costs for medical care, permanent impairment, and paid lost days. The high rates of overexertion injuries among these workers is consistent with known ergonomic stresses on drywall jobs. However, these workers are also at high risk of acute traumatic injuries.     

Utilization of Mental Health Services Among Adolescents in Community-Based Substance Abuse Outpatient Clinics

This study examined the rates and correlates of self-reported receipt for mental health services among 1,190 adolescents, aged 12–19, who were admitted to community-based substance abuse outpatient clinics and had a co-occurring mental health problem. Utilization of mental health service was ascertained 3 months post-intake. About one third (35%) of adolescents with a co-occurring mental health problem identified at intake received mental health service in the 3 months after treatment entry. After holding other correlates constant, history of mental health treatment, suicidal behavior, family history of mental disorder and insurance coverage at intake were associated with mental health service utilization at the 3-month follow up. Predictors of service utilization varied by gender and racial/ethnic status. Implications for integrated substance use and mental health services are discussed.     

Estimating Determinants of Multiple Treatment Episodes for Substance Abusers

BACKGROUND: Health services researchers have increasingly used hazard functions to examine illness or treatment episode lengths and related treatment utilization and treatment costs. There has been little systematic hazard analysis, however, of mental health/substance abuse (MH/SA) treatment episodes. AIMS OF THE STUDY: This article uses proportional hazard functions to characterize multiple treatment episodes for a sample of insured clients with at least one alcohol or drug treatment diagnosis over a three-year period. It addresses the lengths and timing of treatment episodes, and the relationships of episode lengths to the types and locations of earlier episodes. It also identifies a problem that occurs when a portion of the sample observations is ?possibly censored. Failure to account for sample censoring will generate biased hazard function estimates, but treating all potentially censored observations as censored will overcompensate for the censoring bias. METHODS: Using insurance claims data, the analysis defines health care treatment episodes as all events that follow the initial event irrespective of diagnosis, so long as the events are not separated by more than 30 days. The distribution of observations ranges from 1 day to 3 years, and individuals have up to 10 episodes. Due to the data collection process, observations may be right censored if the episode is either ongoing at the time that data collection starts, or when the data collection effort ends. The Andersen-Gill (AG) and Wei-Lin-Weissfeld (WLW) estimation methods are used to address relationships among individuals multiple episodes. These methods are then augmented by a probit censoring model that estimates censoring probability and adjusts estimated behavioral coefficients and related treatment utilization and treatment costs. There has been little systematic hazard analysis, however, of mental health/substance abuse (MH/SA) treatment episodes. RESULTS: Five sets of variables explain episode duration: (i) individual; (ii) insurance; (iii) employer; (iv) binary, indicating episode diagnosis, location, and sequence; and (v) linkage, relating current diagnoses to previous diagnoses in a sequence. Sociodemographic variables such as age or gender have impacts at both the individual and at the firm level. Coinsurance rates and deductibles also have impacts at the individual and the firm levels. Binary variables indicate that surgical/outpatient episodes were the shortest, and psychiatric/outpatient episodes were the longest. Linkage variables reveal significant impacts of prior alcoholism, drug, and psychiatric episodes on the lengths of subsequent episodes. DISCUSSION: Health care treatment episodes are linked to each other both by diagnosis and by treatment location. Both the AG and the WLW models have merit for treating multiple episodes. The AG model permits more flexibility in estimating hazards, and allows researchers to model impacts of prior diagnoses on future episodes. The WLW model provides a convenient way to examine impacts of sociodemographic variables across episodes. It also provides efficient pooled estimates of coefficients and their standard errors. LIMITATIONS: The insurance claims data set covers 1989 through 1991, predating current managed care plans. It cannot identify untreated substance abusers, nor can it identify those with out-of-plan use. It provides treatment information only if services are covered by the insurance plan and are defined with a substance abuse diagnosis code. Like medical records, insurance claims will not specify substance abuse treatment received within the context of other health care (and thus identified by a non-substance abuse diagnosis code) or community services. IMPLICATIONS FOR POLICY AND RESEARCH: This article characterizes multiple health treatment episodes for a sample of insured clients with at least one alcohol or drug treatment diagnosis within a three-year period. We identify both individual and employer effects on episode length. We find that episode lengths vary by the diagnosis type, and that the lengths (and by inference cost and utilization) may depend on the treatments that occurred in previous episodes. We also recognize that health care or illness episodes may be ongoing at times of health care events prior to the ends of data collection periods, leading to uncertain episode lengths. Corresponding estimates of costs or utilization are also uncertain. We provide a method that adjusts the episode lengths according to the probability of censoring.     

Health Care Utilization and Costs Associated with Physical and Nonphysical-Only Intimate Partner Violence

Objective. To estimate health care utilization and costs associated with the type of intimate partner violence (IPV) women experience by the timing of their abuse.
Methods. A total of 3,333 women (ages 18–64) were randomly sampled from the membership files of a large health plan located in a metropolitan area and participated in a telephone survey to assess IPV history, including the type of IPV (physical IPV or nonphysical abuse only) and the timing of the abuse (ongoing; recent, not ongoing but occurring in the past 5 years; remote, ending at least 5 years prior). Automated annual health care utilization and costs were assembled over 7.4 years for women with physical IPV and nonphysical abuse only by the time period during which their abuse occurred (ongoing, recent, remote), and compared with those of never-abused women (reference group).
Results. Mental health utilization was significantly higher for women with physical or nonphysical abuse only compared with never-abused women—with the highest use among women with ongoing abuse (relative risk for those with ongoing abuse: physical, 2.61; nonphysical, 2.18). Physically abused women also used more emergency department, hospital outpatient, primary care, pharmacy, and specialty services; for emergency department, pharmacy, and specialty care, utilization was the highest for women with ongoing abuse. Total annual health care costs were higher for physically abused women, with the highest costs for ongoing abuse (42 percent higher compared with nonabused women), followed by recent (24 percent higher) and remote abuse (19 percent higher). Women with recent nonphysical abuse only had annual costs that were 33 percent higher than nonabused women.
Conclusion. Physical and nonphysical abuse contributed to higher health care utilization, particularly mental health services utilization.     

Substance abuse benefits: still limited after all these years

Using data from a special supplement to the 2006 Kaiser/HRET Employer Health Benefits Survey, this study examines the state of employer-sponsored insurance substance abuse benefits in 2006 and how benefits compare to coverage for medical-surgical services. In 2006, 88 percent of insured workers had some coverage for substance abuse services. Current substance abuse benefits, however, do not provide the same protection afforded under medical-surgical benefits. Instead, substance abuse benefits are characterized by higher cost sharing and annual limits and lifetime limits on inpatient and outpatient care. These limits generally do not exist for other medical conditions and have increased since 1990.     

Child Care in Outpatient Substance Abuse Treatment Facilities for Women: Findings from the 2008 National Survey of Substance Abuse Treatment Services

Mothers with substance use disorders who lack access to child care are often unable to enter or remain in substance abuse treatment. This study examined the availability of child care in outpatient substance abuse treatment facilities and whether or not certain facility characteristics were associated with the availability of child care. Using data from the 2008 National Survey of Substance Abuse Treatment Services, 6.5% of outpatient substance abuse treatment facilities that served women provided child care. The results of multivariate logistic regression found that child care was more common among facilities that were located in metropolitan areas, were operated by non-profit or government agencies, received public funding, or provided free services or other ancillary services including case management, domestic violence counseling, and transportation assistance. Facilities that served only women had more than three times higher odds of providing child care compared with mixed-gender facilities. Further research is needed to identify strategies for expanding child care in outpatient substance abuse treatment facilities.     

Detecting symptoms of alcohol abuse in primary care settings

BACKGROUND: Studies on alcohol abuse are frequently based on patients who meet minimum diagnostic criteria, thus ignoring patients with individual symptoms of harmful or hazardous use. Consequently, we are unable to characterize alcohol-abusing patients with sufficient clarity to effectively focus screening for primary prevention. OBJECTIVE: To determine the prevalence of harmful and hazardous use of alcohol, assess screening instruments for detecting alcohol abuse or dependence, and assess the impact of alcohol use on other diagnoses treated in outpatient settings. DESIGN: Survey (cross-sectional study). SETTING: Hospital-based outpatient clinic. PARTICIPANTS: Three hundred randomly selected adults (aged 18 years and older). MAIN OUTCOME MEASURE: Diagnosis of alcohol abuse or dependence based on the Diagnostic Interview Schedule (DIS). RESULTS: About 18% met DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) criteria of abuse or dependence while almost 50% had at least one symptom of harmful or hazardous use. The T-ACE questionnaire, a modified version of the CAGE questionnaire, was the most effective screening instrument for both men and women. Selected diagnoses, personal characteristics such as family history of alcohol abuse, and self-reported patterns of alcohol use could identify patients likely to meet diagnostic criteria. CONCLUSIONS: Many symptoms of substance use disorders are not adequately addressed in outpatient practice. Little is known about how alcohol use in varying quantities affects health care utilization and treatment of conditions commonly seen in outpatient medicine. Consequently, we lack a full appreciation of the burden of disease borne by alcohol use and have yet to achieve a universally accepted method of approaching primary and secondary prevention of alcohol-related problems.     

The administrative control system of substance abuse managed care

OBJECTIVE: This article searches for the dimensions of the administrative structures in outpatient substance abuse managed care that control the behavior of agency providers. It also ascertains how these dimensions, and several financial mechanisms, affect key aspects of the providers services: the average number of sessions of care that are delivered, the rate of completion of care, and the (estimated) rate at which clients control their substance use. DATA SOURCES: The data were collected in 1999 for this investigation. STUDY DESIGN: These data come from a nationally representative, cross-sectional sample of individual contracts between outpatient drug treatment providers and the Behavioral Health Managed Care Organizations (BHMCOs) that are empowered to regulate the delivery of services. Provider responses are analyzed here. DATA COLLECTION METHODS: Factor analyses at a contract level examine the structural dimensions of the control system. Multivariate analyses at the same level rely on generalized linear models to predict the dependent variables by the structural dimensions and financial mechanisms. FINDINGS: The factor analyses suggest that there are six multiple variable structural dimensions. The multivariate analyses suggest that the dimension that mandates follow-up of discharged clients tends to relate to more sessions of care and perhaps a higher rate of service completion. Most other dimensions are found to relate to fewer sessions of care, lower rates of service completion, or lower rates of control of substance abuse. No structural dimension relates to all dependent variables. Financial mechanisms evince varying relations to the sessions of care. They rarely relate to the other dependent variables. CONCLUSION: The results generally suggest that providers, payers, or policymakers might affect service provision by selecting BHMCOs that stress particular structural dimensions and financial mechanisms. However, managed care contracts most heavily rely on structural dimensions that restrict treatment sessions and fail to predict superior client outcomes.     

Surveillance of work-related musculoskeletal injuries among union carpenters

Combined data sources, including union administrative records and workers' compensation claims, were used to construct event histories for a dynamic cohort of union carpenters from Washington State during the period 1989–1992. Person-time at risk and the events of interest were stratified by age, sex, time in the union, and predominant type of carpentry work. Poisson regression techniques were used to identify subgroups at greatest risk of filing claims for a variety of musculoskeletal disorders defined by ANSI codes for body part injured and injury nature. Distinguishing different kinds of musculoskeletal disorders, even crudely with ANSI codes, led to different conclusions about the effects of the explanatory variables. Among older workers, the rates of fractures of the foot were higher, while rates of contusions of the hand and foot were lower. Women had higher rates of sprain/strains and nerve conditions of the wrist/forearm. Higher rates of injuries to the axial skeleton were seen among carpenters who did predominantly light commercial and drywall work, while piledrivers had lower rates of these injuries. Drywall workers had higher rates of sprains to the ankle/lower leg. Workers who were members of the union as long as four years had lower risks for the vast majority of musculoskeletal disorders studied. Similar patterns were seen for more serious claims that resulted in paid lost time from work. Am. J. Ind. Med. 32:629–640, 1997. © 1997 Wiley-Liss, Inc.     

Patient Satisfaction with Care in Programs for Low Income Individuals

Although a variety of public and private programs provide care for low-income individuals, little is known about patient satisfaction across these programs. The objective of this study was to examine patient satisfaction across a variety of health insurance programs. A survey was conducted of randomly selected adults in Kentucky who had an outpatient visit in the past 12 months (616 with private insurance, 683 Medicaid recipients, 287 in private sector charity program for uninsured indigents). Patient satisfaction with multiple dimensions of their most recent outpatient visit was assessed. All insurance groups were generally satisfied with the care received in their most recent visit. For all 8 dimensions of patient satisfaction, the private insurance group was significantly higher than the other groups. In a model controlling for standard demographic and health status variables, higher overall satisfaction with the visit was positively related to higher income and higher mental health functional status. The insurance category variable had no significant relationship to overall satisfaction with the visit. Although patients receiving care through health insurance programs for low-income individuals are generally satisfied with the services, there is an indication that low-income individuals, regardless of insurance type, are less satisfied with the care they receive.     

Alcohol,drug abuse,and mental health care for uninsured and insured adults

OBJECTIVE: To compare adults with different insurance coverage in care for alcohol, drug abuse, and mental health (ADM) problems. DATA SOURCES/STUDY SETTING: From a national telephone survey of 9,585 respondents. DESIGN: Follow-up of adult participants in the Community Tracking Study. DATA COLLECTION: Self-report survey of insurance plan (Medicare, Medicaid, unmanaged, fully, or partially managed private, or uninsured), ADM need, use of ADM services and treatments, and satisfaction with care in the last 12 months. PRINCIPAL METHODS: Logistic and linear regressions were used to compare persons by insurance type in ADM use. PRINCIPAL FINDINGS: The likelihood of ADM care was highest under Medicaid and lowest for the uninsured and those under Medicare. Perceived unmet need was highest for the uninsured and lowest under Medicare. Persons in fully rather than partially managed private plans tend to be more likely to have ADM care and ADM treatments given need. Satisfaction with care was high in public plans and low for the uninsured. CONCLUSIONS: The uninsured have the most problems with access to and quality of ADM care, relative to the somewhat comparable Medicaid population. Persons in fully managed plans had better rather than worse access and quality compared to partially managed plans, but findings are exploratory. Despite low ADM use, those with Medicare tend to be satisfied. Across plans, unmet need for ADM care was high, suggesting changes are needed in policy and practice.     

Substance abuse among sexually abused adolescents and their families

The concurrence of substance abuse and history of sexual abuse among adolescents has prompted this study of substance abuse patterns among families of adolescents who report incest or extrafamilial sexual abuse. A total of 3,179 ninth-grade students in a rural midwestern state completed a survey that included questions about individual and family substance abuse. Adolescents who had been sexually abused were more likely to report substance abuse for themselves as well as for members of their immediate families. They were also more likely to report that they used substances because of family problems, school problems, and because they were sad, lonely, or angry. Adolescents reporting a parent with an alcohol or a drug problem were more likely to use cigarettes, marijuana, alcohol, or “speed.” Adolescents experiencing extrafamilial abuse reported more alcohol abuse and more alcohol-related problems than those who experienced incest. There were similar reports of parental and familial alcohol and drug problems among those experiencing incest and those experiencing extrafamilial abuse. Those with drug-abusing parents, however, were most likely to report some kind of sexual abuse history.     

Cost-effectiveness of public sector substance abuse treatment

Costs and cost-effectiveness of public sector substance abuse treatment in 2 California counties with similar substance abuse treatment system histories are compared; one county (MidState) has adopted managed care principles. As hypothesized, MidState's costs for the index treatment episode were significantly lower than SouthState's, although unexpectedly because of lower outpatient utilization. Treatment benefits in the 7 Addiction Severity Index functional areas were examined through cost-effectiveness analyses. MidState can claim greater cost-effectiveness for its treatment dollars for significant improvement in alcohol and medical functioning (compared to unsuccessful clients and those reporting no problems). When comparing both improved clients and those maintaining no problems to unsuccessful clients, MidState is more cost-effective for improving alcohol, medical, legal, and family/social functioning; and 3 outcomes important to community stakeholders and taxpayers (legal, medical, and psychiatric functioning) are more cost-effective than alcohol, drug, and employment improvement.     

Privatisation & marketisation of post-birth care: the hidden costs for new mothers

Introduction

Health care financing reforms in both China and Vietnam have resulted in greater financial difficulties in accessing health care, especially for the rural poor. Both countries have been developing rural health insurance for decades. This study aims to evaluate and compare equity in access to health care in rural health insurance system in the two countries.

Methods

Household survey and qualitative study were conducted in 6 counties in China and 4 districts in Vietnam. Health insurance policy and its impact on utilization of outpatient and inpatient service were analyzed and compared to measure equity in access to health care.

Results

In China, Health insurance membership had no significant impact on outpatient service utilization, while was associated with higher utilization of inpatient services, especially for the higher income group. Health insurance members in Vietnam had higher utilization rates of both outpatient and inpatient services than the non-members, with higher use among the lower than higher income groups. Qualitative results show that bureaucratic obstacles, low reimbursement rates, and poor service quality were the main barriers for members to use health insurance.

Conclusions

China has achieved high population coverage rate over a short time period, starting with a limited benefit package. However, poor people have less benefit from NCMS in terms of health service utilization. Compared to China, Vietnam health insurance system is doing better in equity in health service utilization within the health insurance members. However with low population coverage, a large proportion of population cannot enjoy the health insurance benefit. Mutual learning would help China and Vietnam address these challenges, and improve their policy design to promote equitable and sustainable health insurance.     

Controlling workers' compensation medical care use and costs through utilization management.

Little is known about the performance of utilization management (UM) programs, which are now widely used within the workers' compensation system to contain medical costs and improve quality. UM programs focus largely on hospital care and rely on preadmission and concurrent reviews to authorize hospital admissions and continued stays. We obtained data from a large UM program representing a national sample of 9319 workers' compensation patients whose medical care was reviewed between 1991 and 1993. We analyzed these data to determine the denial rate for hospital admission and outpatient surgery and the frequency of length-of-stay restrictions among hospitalized patients. The denial rate was approximately 2% to 3% overall, but many of the denials were later reversed. On average, the UM program reduced the length of stay by 1.9 days relative to the number of days of care requested. The estimated gross cost savings resulting from reduced hospitalization time and decreased outpatient care was approximately $5 million. UM programs may offer a viable approach to cost containment within the workers' compensation system. Their value as a tool to improve the quality of care for workers' compensation patients remains to be demonstrated.     

Substance abuse and the uninsured worker in the United States

Although millions of US workers lack health insurance, the relationship of insurance coverage with substance abuse and access to workplace treatment services remains unexplored. Our analysis shows uninsured workers have higher rates of heavy drinking and illicit drug use than insured workers. Young and part-time workers are, moreover, less likely to have insurance coverage than workers with lower substance abuse risks. Compared to the insured, uninsured workers have less access to employee assistance programs (EAPs) and less drug and alcohol testing by employers. The effectiveness of workplace substance abuse programs and policies designed for insured populations is untested among uninsured workers. Issues include EAP effectiveness with referrals to public treatment and the return on investment for adding coverage of substance abuse treatment. Workers in countries with universal health insurance but inadequate treatment capacity may face similar problems to uninsured workers in the US.
