The excess medical cost and health problems of family members of persons diagnosed with alcohol or drug problems.

BACKGROUND: Having a family member with substance use problems affects family functioning, which may lead to increased medical problems and increased health care utilization and costs in the other family members. AIM: We sought to estimate the excess medical costs and prevalence of diagnosed health conditions of family members of persons with an alcohol or drug diagnosis (AOD) compared with the family members of similar persons without an AOD. METHODS: Using a large health plan's administrative databases, we identified persons who received an AOD between 2001 and 2004 and a similar group of persons with no AOD during that time. Using a hierarchical linear mixed model, we compared the cost and utilization of the family members of the AOD and non-AOD patients in the 2 years prior to the AOD patient's first AOD. Using logistic regression, we determined whether the family members of patients with AODs were more likely than comparison family members to be diagnosed with medical conditions. RESULTS: Family members of patients with AODs had greater health care costs than comparison family members in the second year before the index date (490 dollars) and in the year before the index date (433 dollars). This was the case for both adult and child family members. They also were more likely to be diagnosed with many medical conditions, especially substance abuse and depression. CONCLUSIONS: Family members of patients with AODs have greater health care costs and are more likely to be diagnosed with a number of medical conditions than family members of similar persons without an AOD.

Progress in pediatric asthma surveillance I: the application of health care use data in Alameda County, California.

INTRODUCTION: The ability to conduct community-level asthma surveillance is increasingly crucial for public health programming and child health advocacy. We explored the potential and limitations of health care use records from both public and private sources for asthma surveillance in a California county. METHODS: We combined administrative patient record data from Kaiser Permanente of Northern California and Medi-Cal (the California Medicaid program) for Alameda County residents during 2001. We assessed the resulting data set for completeness, population representation, consistency with external data, and internal indicator consistency. RESULTS: Our resulting data set included records for 226,383 children younger than 18 years. Completeness of Medicaid data was affected by managed care market share, reducing our usable data set size to 176,789, approximately equal to one of every two children in the county or one of every 3 person-months. External data documenting hospitalization rates due to asthma were poorly correlated with hospitalization rates (r = 0.2120, P = .20) but highly correlated with emergency department visits (r = 0.8607, P <.001) in the resulting data set. High internal consistency of indicators suggested that the data set represented a broad spectrum of health care access and quality of care congruent with clinical aspects of the disease. CONCLUSION: The utility of these data is affected by logistical and administrative factors, including the health care payment structure and the market shares of care providers. These factors can be expected to similarly affect the utility of this approach in other counties. Our ability to generate county-level health statistics for comparison with other locations was limited, although the data set appeared well suited for within-county geographic analysis. In light of these findings, these data have the potential to expand the local health surveillance capacity of communities.

Progress in pediatric asthma surveillance II: geospatial patterns of asthma in Alameda County, California.

INTRODUCTION: As with many diseases, the epidemic of asthma among children over the past few decades has been shaped by a social and environmental context that is becoming progressively more evident. Commonly used methods for asthma surveillance, however, are based on national rather than local data. The purpose of this study was to develop high-resolution asthma surveillance techniques responsive to the needs of health care professionals and local child health and social justice advocates. METHODS: We assembled a working data set of health care use records from 2001 from public and private sources covering 1.7 million person-months among children younger than 18 years in Alameda County, California. Health care use was categorized by type and analyzed by census tract demographic information. Images of the geographic distribution of health service events were created using density estimation mapping with overlapping 0.5-mile (805-m) radius spatial buffers, and statistical significance (two-tailed P & .05) was estimated using a Monte Carlo simulation algorithm. RESULTS: High-poverty communities had higher rates of emergency department visits due to asthma than low-poverty communities but had lower rates for indicators of quality primary asthma care. Geospatial analysis enabled visualization of this phenomenon; it further detected areas with elevated emergency department visit rates and potentially related environmental hazards in and around communities of concern. Areas of the county not previously considered to be deeply burdened by asthma were identified as having high emergency department visit rates. CONCLUSION: The assembly and high-resolution geospatial analysis of health care use data contributed to a more detailed depiction of pediatric asthma disparities than was previously available to community members, public health professionals, and clinicians. Information generated using these techniques facilitated discussion among stakeholders of the environmental and social contexts of asthma and health disparities in general. Proceedings of group evaluations suggested that the material aided in the translation of data describing spatial variations in health event risk to address specific community experiences and concerns.

Attention-deficit/hyperactivity disorder in children: excess costs before and after initial diagnosis and treatment cost differences by ethnicity.

OBJECTIVES: To estimate the excess costs for children in the years surrounding initial diagnosis of attention-deficit/hyperactivity disorder (ADHD) and to estimate differences in treatment costs by ethnicity. DESIGN: We identified children diagnosed with ADHD and estimated their health service costs in the 2 years before and 2 years after initial diagnosis of ADHD. Costs were compared with those for children without ADHD. We adjusted for age, sex, ethnicity, pharmacy co-pay, estimated family income, coexisting mental health disorders, and chronic medical conditions. SETTING: Nonprofit, integrated health care delivery system in northern California from January 1, 1996, to December 31, 2004. PARTICIPANTS: Children aged 2 to 10 years with (n = 3122) and without (n = 15 899) ADHD. Main Exposure Attention-deficit/hyperactivity disorder. MAIN OUTCOME MEASURES: Health care costs and use in the years before and after initial ADHD diagnosis as well as costs of ADHD-related services. RESULTS: Compared with children without ADHD, children with ADHD had mean costs that were $488 more in the second year before their ADHD diagnosis, $678 more in the year before their diagnosis, $1328 more in the year after their diagnosis, and $1040 more in the second year after their diagnosis. Asian Americans diagnosed with ADHD had lower total ADHD-related mean costs per year than white Americans diagnosed with ADHD ($221 lower), and Asian Americans, African Americans, and Hispanic Americans all had lower ADHD-related pharmacy mean costs than white Americans ($95, $63, and $77 lower, respectively). CONCLUSIONS: Children with ADHD use significantly more health services before and after their diagnosis than children without ADHD. Among children diagnosed with ADHD, nonwhite Americans (especially Asian Americans) use fewer ADHD-related services than white Americans.

Cost-effectiveness of pneumococcal conjugate vaccine: evidence from the first 5 years of use in the United States incorporating herd effects.

BACKGROUND: Pneumococcal conjugate vaccine (PCV) has been in routine use in the United States for 5 years. Prior U.S. cost-effectiveness analyses have not taken into account the effect of the vaccine on nonvaccinated persons. METHODS: We revised a previously published model to simulate the effects of PCV on children vaccinated between 2000 and 2004, and to incorporate the effect of the vaccine in reducing invasive pneumococcal disease (IPD) in nonvaccinated persons during those years. Data from the Active Bacterial Core Surveillance of the Centers for Disease Control and Prevention (2000-2004) were used to estimate changes in the burden of IPD in nonvaccinated adults since the introduction of PCV (compared with the baseline years 1997-1999). Results combined the simulated effects of the vaccine on the vaccinated and nonvaccinated populations. RESULTS: Before incorporating herd effects in the model, the PCV was estimated to have averted 38,000 cases of IPD during its first 5 years of use at a cost of dollar 112,000 per life-year saved. After incorporating the reductions in IPD for nonvaccinated individuals, the vaccine averted 109,000 cases of IPD at a cost of dollar 7500 per life-year saved. When the herd effect was assumed to be half that of the base case, the cost per life-year saved was dollar 18,000. CONCLUSIONS: IPD herd effects in the nonvaccinated population substantially reduce the cost, and substantially improve the cost-effectiveness, of PCV. The cost-effectiveness of PCV in actual use has been more favorable than predicted by estimates created before the vaccine was licensed.

Cost-sharing for emergency care and unfavorable clinical events: findings from the safety and financial ramifications of ED copayments study.

OBJECTIVE: To evaluate the effect of emergency department (ED) copayment levels on ED use and unfavorable clinical events. Data Source/Study Setting. Kaiser Permanente-Northern California (KPNC), a prepaid integrated delivery system. STUDY DESIGN: In a quasi-experimental longitudinal study with concurrent controls, we estimated rates of ED visits, hospitalizations, ICU admissions, and deaths associated with higher ED copayments relative to no copayment, using Poisson random effects and proportional hazard models, controlling for patient characteristics. The study period began in January 1999; more than half of the population experienced an employer-chosen increase in their ED copayment in January 2000. DATA COLLECTION/EXTRACTION METHODS: Using KPNC automated databases, the 2000 U.S. Census, and California state death certificates, we collected data on ED visits and unfavorable clinical events over a 36-month period (January 1999 through December 2001) among 2,257,445 commercially insured and 261,091 Medicare insured health system members. PRINCIPAL FINDINGS: Among commercially insured subjects, ED visits decreased 12 percent with the $20-35 copayment (95 percent confidence interval [CI]: 11-13 percent), and 23 percent with the $50-100 copayment (95 percent CI: 23-24 percent) compared with no copayment. Hospitalizations, ICU admissions, and deaths did not increase with copayments. Hospitalizations decreased 4 percent (95 percent CI: 2-6 percent) and 10 percent (95 percent CI: 7-13 percent) with ED copayments of $20-35 and $50-100, respectively, compared with no copayment. Among Medicare subjects, ED visits decreased by 4 percent (95 percent CI: 3-6 percent) with the $20-50 copayments compared with no copayment; unfavorable clinical events did not increase with copayments, e.g., hospitalizations were unchanged (95 percent CI: -3 percent to +2 percent) with $20-50 ED copayments compared with no copayment. CONCLUSIONS: Relatively modest levels of patient cost-sharing for ED care decreased ED visit rates without increasing the rate of unfavorable clinical events.

A comparison of health care utilization and costs of children with and without autism spectrum disorders in a large group-model health plan.

OBJECTIVE: Data on the current costs of medical services for children with autism spectrum disorders are lacking. Our purpose for this study was to compare health care utilization and costs of children with and without autism spectrum disorders in the same health plan. PATIENTS AND METHODS: Participants included all 2- to 18-year-old children with autism spectrum disorders (n = 3053) and a random sample of children without autism spectrum disorders (n = 30529) who were continuously enrolled in the Kaiser Permanente Medical Care Program in northern California between July 1, 2003, and June 30, 2004. Data on health care utilization and costs were derived from health plan administrative databases. MAIN OUTCOME MEASURES: Outcome measures included mean annual utilization and costs of health services per child. RESULTS: Children with autism spectrum disorders had a higher annual mean number of total clinic (5.6 vs 2.8), pediatric (2.3 vs 1.6), and psychiatric (2.2 vs 0.3) outpatient visits. A higher percentage of children with autism spectrum disorders experienced inpatient (3% vs 1%) and outpatient (5% vs 2%) hospitalizations. Children with autism spectrum disorders were nearly 9 times more likely to use psychotherapeutic medications and twice as likely to use gastrointestinal agents than children without autism spectrum disorders. Mean annual member costs for hospitalizations (550 dollars vs 208 dollars), clinic visits (1373 dollars vs 540 dollars), and prescription medications (724 dollars vs 96 dollars) were more than double for children with autism spectrum disorders compared with children without autism spectrum disorders. The mean annual age- and gender-adjusted total cost per member was more than threefold higher for children with autism spectrum disorders (2757 dollars vs 892 dollars). Among the subgroup of children with other psychiatric conditions, total mean annual costs were 45% higher for children with autism spectrum disorders compared with children without autism spectrum disorders; excess costs were largely explained by the increased use of psychotherapeutic medications. CONCLUSIONS: The utilization and costs of health care are substantially higher for children with autism spectrum disorders compared with children without autism spectrum disorders. Research is needed to evaluate the impact of improvements in the management of children with autism spectrum disorders on health care utilization and costs.

Hospital-level rates of fluoroquinolone use and the risk of hospital-acquired infection with ciprofloxacin-nonsusceptible Pseudomonas aeruginosa.

BACKGROUND: In recent years, Pseudomonas aeruginosa has become increasingly resistant to fluoroquinolones, and fluoroquinolone use in the United States has also increased. Our objective was to determine whether higher hospital-level rates of use of ciprofloxacin, levofloxacin, and moxifloxacin antimicrobials were predictors that a higher proportion of P. aeruginosa isolates from hospital-acquired infections (hereafter, "hospital-acquired isolates") would be nonsusceptible to ciprofloxacin. METHODS: We identified all hospital-acquired isolates from 14 hospitals in the Northern California Kaiser Permanente health care delivery system between 1998 and 2003 and determined their susceptibility to ciprofloxacin. For each facility, we determined the number of days of fluoroquinolone use per 1000 patient-days, by calendar quarter. We used a logistic regression model to analyze the data, with susceptibility status as the outcome variable. Hospital-level rates of use of the 3 fluoroquinolones were the predictors of interest; we adjusted for year, for use of nonquinolone antimicrobials, and for patient variables, including the number of days spent in the hospital in the prior year and fluoroquinolone use in the prior year. The model tested whether isolates from those facilities with higher rates of use of antimicrobials were more likely to be nonsusceptible to ciprofloxacin. RESULTS: Of 6099 isolates tested, 15% were not susceptible to ciprofloxacin. The nonsusceptibility rate increased from 9% to 20% between 1998 and 2003. Both the overall rate of use at the hospital and prior patient-specific use of ciprofloxacin, levofloxacin, and moxifloxacin were found to be independent predictors that a subsequent P. aeruginosa isolate would be nonsusceptible to ciprofloxacin. CONCLUSIONS: Higher hospital-level rates of use of ciprofloxacin, levofloxacin, and moxifloxacin are each associated with an increased proportion of hospital-acquired P. aeruginosa isolates being nonsusceptible to ciprofloxacin.

Values for preventing influenza-related morbidity and vaccine adverse events in children.

BACKGROUND: Influenza vaccination recently has been recommended for children 6-23 months old, but is not currently recommended for routine use in non-high-risk older children. Information on disease impact, costs, benefits, risks, and community preferences could help guide decisions about which age and risk groups should be vaccinated and strategies for improving coverage. The objective of this study was to measure preferences and willingness-to-pay for changes in health-related quality of life associated with uncomplicated influenza and two rarely-occurring vaccination-related adverse events (anaphylaxis and Guillain-Barré syndrome) in children. METHODS: We conducted telephone interviews with adult members selected at random from a large New England HMO (n = 112). Respondents were given descriptions of four health outcomes: uncomplicated influenza in a hypothetical 1-year-old child of their own, uncomplicated influenza in a hypothetical 14-year-old child of their own, anaphylaxis following vaccination, and Guillain-Barré syndrome. "Uncomplicated influenza" did not require a physician's visit or hospitalization. Preferences (values) for these health outcomes were measured using time-tradeoff and willingness-to-pay questions. Time-tradeoff questions asked the adult to assume they had a child and to consider how much time from the end of their own life they would be willing to surrender to avoid the health outcome in the child. RESULTS: Respondents said they would give a median of zero days of their lives to prevent an episode of uncomplicated influenza in either their (hypothetical) 1-year-old or 14-year-old, 30 days to prevent an episode of vaccination-related anaphylaxis, and 3 years to prevent a vaccination-related case of Guillain-Barré syndrome. Median willingness-to-pay to prevent uncomplicated influenza in a 1-year-old was $175, uncomplicated influenza in a 14-year-old was $100, anaphylaxis $400, and Guillain-Barré syndrome $4000. The median willingness-to-pay for an influenza vaccination for their children with no risk of anaphylaxis or Guillain-Barré syndrome was $50 and $100, respectively. CONCLUSION: Most respondents said they would not be willing to trade any time from their own lives to prevent uncomplicated influenza in a child of their own, and the time traded did not vary by the age of the hypothetical affected child. However, adults did indicate a willingness-to-pay to prevent uncomplicated influenza in children, and that they would give more money to prevent the illness in a 1-year-old than in a 14-year-old. Respondents also indicated a willingness to pay a premium for a vaccine without any risk of severe complications.

Hazardous drinkers and drug users in HMO primary care: prevalence, medical conditions, and costs.

BACKGROUND: There exists substantial evidence that individuals with alcohol and drug disorders have heightened comorbidities and health care costs. However, little is known about the larger population of "hazardous" drinkers (those whose consumption increases their "risk of physical and psychological harm") and drug users. METHODS: A sample of 1,419 patients from HMO primary care clinics was screened for hazardous drinking and drug use. Health plan databases were used to examine medical conditions and health care costs of hazardous drinkers and drug users in the year prior to screening, in comparison to 13,347 patients from the same clinics, excluding those screened. RESULTS: We found a prevalence of 7.5% for hazardous drinking and 3.2% for drug use in primary care (10% had at least one of the two problems). Hazardous drinkers and drug users had heightened prevalences for eight medical conditions, including costly conditions such as injury and hypertension, and psychiatric conditions. Medical costs for the year examined were not higher, except for those who also had psychiatric conditions. CONCLUSIONS: The prevalence of hazardous drinking and drug use was similar to hypertension and diabetes. Hazardous drinkers and drug users' heightened medical conditions, especially those related to alcohol and drug abuse, indicate that screening and brief intervention at this lower threshold of hazardous drinking and drug use will detect individuals with health risks sooner. Optimal treatment and prevention of some medical disorders may require identification and intervention of underlying hazardous alcohol or drug use.

Routine ultrasonography compared with maternal serum alpha-fetoprotein for neural tube defect screening.

OBJECTIVE: This study was done to estimate the value of prenatal maternal serum alpha-fetoprotein (MSAFP) screening compared with that of routine ultrasonography in the diagnosis of neural tube defects (NTDs). METHODS: An integrated database was used retrospectively to identify cases of NTDs among 219,000 consecutive pregnancy outcomes observed during a 7-year period at 40 Kaiser Permanente facilities in Northern California. We specifically examined types of NTD and the tests used to diagnose cases. RESULTS: We identified 189 NTD cases, 102 of which had received MSAFP screening. Results of MSAFP testing were negative in 25 (25%) of these 102 cases. Without other testing, these 25 NTD diagnoses would have been missed. These included 15 (38%) of the 40 spina bifida cases screened, 6 (67%) of the 9 encephalocele cases screened, and 4 (8%) of the 53 anencephaly cases screened. Of the 186 NTD cases diagnosed prenatally, 115 (62%) were initially detected by routine ultrasonography administered during the second trimester without knowledge of MSAFP values; 69 (37%) were diagnosed by targeted ultrasonography after MSAFP screening indicated a higher risk for NTD; and 2 (1%) were diagnosed by pathology examination after miscarriage. CONCLUSION: Compared with MSAFP performed alone for screening, routine second-trimester ultrasonography was more likely to discover an NTD.

Relationship between use of psychiatric services and five-year alcohol and drug treatment outcomes.

OBJECTIVE: The objective of this study was to examine the relationship between use of psychiatric services and alcohol and drug treatment outcomes five years after such treatment. It was anticipated that receipt of psychiatric services would predict long-term abstinence. METHODS: A sample of 604 outpatients from a managed care organization's chemical dependency program was interviewed about substance use and severity of psychiatric symptoms at baseline and at five years. Patients were required to have at least three years of membership in the health plan during the five years after intake. Severity of psychiatric symptoms was categorized as zero, low, middle, or high. Use of psychiatric services was ascertained on the basis of administrative data from the health plan. Logistic regression analysis was used to assess the relationship between receipt of psychiatric services during the five years after intake and abstinence at five years. Results were adjusted for individual, treatment, and extra-treatment characteristics; severity of psychiatric symptoms at baseline; and other contacts with the health system. RESULTS: Patients who received a threshold level of psychiatric services (an average of at least 2.1 hours a year) were significantly more likely to be abstinent at five years than patients who received less than 2.1 hours a year. CONCLUSIONS: The use of psychiatric services among patients with chemical dependency is associated with enhanced long-term outcomes.

Readmission among chemical dependency patients in private, outpatient treatment: patterns, correlates and role in long-term outcome.

OBJECTIVE: Similar to other chronic conditions, chemical dependency is a chronic, relapsing condition. Yet predominant treatment models do not provide ongoing, long-term treatment services; readmission is the available long-term care for alcohol and drug patients. We examine readmission patterns and the role of readmission in 5-year outcome in chemical dependency patients in a private, integrated health plan. METHOD: We used health plan utilization databases and self-report at 5-year follow-up to measure readmission and routine primary care services in 647 chemical dependency outpatients from a private health plan. Logistic regression was used to examine whether readmission and primary medical care predicted abstinence at 5 years. RESULTS: Controlling for demographic characteristics and dependence type, higher odds for past-year alcohol and drug abstinence at 5 years following treatment was predicted by having been readmitted in the first 4 years after index episode (odds ratio =1.59, p = .006). Receiving routine medical care predicted past 30-day (but not past-year) abstinence at 5-year follow-up. CONCLUSIONS: The relationship of readmissions to better outcome at 5 years suggests that long-term continuing care may benefit patients' long-term outcomes. More research is needed on the relationship of primary medical care to long-term outcome in chemical dependency patients.

Preferences and willingness to pay for health states prevented by pneumococcal conjugate vaccine.

OBJECTIVE: To measure parents' and other adults' values for preventing disease associated with pneumococcal infection and to evaluate how including these values changes the economic appraisal of pneumococcal conjugate vaccine. METHODS: Data on preferences and willingness to pay to reduce risk of illness were collected for 6 illnesses that are preventable by pneumococcal conjugate vaccine (simple otitis media, complex otitis media, moderate pneumonia, severe pneumonia, bacteremia, and meningitis) and 1 vaccine-related adverse event (fever and fussiness after vaccine). Interviews were conducted with 2 groups of respondents: 1) parents of children who had experienced 1 or more of the outcomes described in the survey (n = 101) and 2) a US community sample (n = 109). The 30-minute telephone interview used modified time trade-off questions and willingness-to-pay questions. Values from the interview were incorporated in an existing decision-analytic model that simulated the cost-effectiveness and cost-benefit of pneumococcal conjugate vaccine in a hypothetical cohort of newborns. RESULTS: Among parents, the median amount of time that respondents said that they would be willing to trade to avoid diseases ranged from 0 days for otitis media to 1 year for severe pneumonia and 2 years for meningitis. Among the US community sample, the median amounts of time traded were higher, ranging from 7 days for otitis media to 3 years for meningitis. Median willingness-to-pay amounts varied from 100 dollars to prevent 1 episode of otitis media and 500 dollars to reduce the risk of meningitis from 21 in 100 000 to 6 in 100 000 and were similar between parents and community members. Incorporating time trade-off amounts into the existing economic model for pneumococcal conjugate vaccine resulted in cost-effectiveness ratios <10 000 dollars per quality-adjusted life year at a vaccine cost of 58 dollars per dose. CONCLUSIONS: Both parents and community members assign relatively high values to preventing meningitis, pneumonia, and complex otitis media. When the value of preventing pneumococcal diseases is incorporated into economic analyses, pneumococcal conjugate vaccine has a cost-effectiveness ratio in the range of other widely used health interventions.

Short-term alcohol and drug treatment outcomes predict long-term outcome.

INTRODUCTION: Although addiction is recognized as a chronic, relapsing condition, few treatment studies, and none in a commercially insured managed care population, have measured long-term outcomes. We examined the relationship of 6-month treatment outcomes to abstinence 5 years post-treatment, and whether the predictors of abstinence at 5 years were different for those who were, and were not, abstinent at 6 months. METHODS: The sample (N=784) is from an outpatient (day hospital and traditional outpatient) managed care chemical dependency program. Subjects were interviewed at baseline, 6 months, and 5 years. Logistic regression analysis was used to assess which individual, treatment and extra-treatment characteristics predicted alcohol and drug abstinence at 5 years. RESULTS: Abstinence at 6 months was an important predictor of abstinence at 5 years. Among those abstinent at 6 months, predictors of abstinence at 5 years were older age, being female, 12-step meeting attendance, and recovery-oriented social networks. Among those not abstinent at 6 months, being alcohol dependent rather than drug dependent, 12-step meeting attendance, treatment readmission, and recovery-oriented social networks predicted abstinence at 5 years. CONCLUSION: Our findings demonstrate a clear association between short-term and long-term treatment success. In addition, these results strongly support the importance of recovery-oriented social networks for those with good short-term outcomes, and the beneficial impact of readmission for those not initially successful in treatment.

Early discontinuation of treatment for osteoporosis.

PURPOSE: To identify factors associated with early treatment discontinuation of three agents commonly prescribed for women with low bone density. METHODS: A telephone survey was conducted in 2000 to 2001 in a random sample of women aged 45 years or older who had bone density T-scores -1.0 or lower and who had initiated treatment with hormone replacement therapy, raloxifene, oral endronate. Logistic regression was used to estimate adjusted odds ratios for early treatment discontinuation. RESULTS: Among 956 women who were interviewed an average of 7 months after treatment initiation, 334 were taking hormone therapy, and 88 (26%) had discontinued; 256 were taking raloxifene, and 48 (19%) had discontinued (P = 0.03 vs. hormone therapy); and 366 were taking alendronate, and 70(19%) had discontinued (P = 0.02 vs. hormone therapy). Women with bothersome side effects (somewhat bothered: odds ratio [OR] = 4.0; 95% confidence interval [CI]: 2.5 to 6.5; very or extremely bothered: OR = 25; 95% CI: 16 to 39) or who thought that their bone density test results did not show osteoporosis (OR = 1.6; 95% CI: 1.0 to 2.5) were more likely to discontinue therapy, as compared with women reporting regular exercise (OR = 0.7; 95% CI: 0.4 to 1.0) or a willingness to take prescribed medications (OR = 0.6; 95% CI: 0.4 to 0.9). After adjustment for side effects and patient characteristics, the odds of early treatment discontinuation did not differ significantly among treatments. CONCLUSION: Improved adherence to osteoporosis treatment requires that treatment side effects be minimized and women be educated regarding their bone density test results.

Services integration and cost-effectiveness.

Alcohol treatment services are increasingly combined with other health and social services to address the needs of multiple-problem clients. Hence, it has been of growing policy interest to find the most effective and the most cost-effective ways of linking these services. This symposium presents some recent studies in this area. The small but growing body of studies in this area has great potential to inform public policy debates.

Comparing the medical expenses of adults with Medicaid and commercial insurance in a health maintenance organization.

The objective of this study was to compare the health care costs of adults with Medicaid aged 19 to 65 years (n = 29,680) and adults in the same age range with commercial insurance (n = 29,680) who were members of the same health maintenance organization between 1996 and 1998. After adjusting for age and sex, income-eligible Medicaid-insured adults were $35 (29 percent) per month more expensive than commercially insured adults. The medically needy/indigent (excluding "spend-down") were $61 (51 percent) per month more expensive than commercially insured adults, and the blind or disabled were $289 (240 percent) per month more expensive. When the analysis adjusted for health status as well as age and sex, however, income-eligible Medicaid adults were $12 (p = 0.01) per month less costly than commercially insured adults. The costs of Medicaid-insured adults were substantially higher than those of commercially insured adults; these differences were likely due to higher rates of pregnancy and to worse health status among the Medicaid cohort.
