The Effect of a Patient-Provider Educational Intervention to Reduce At-Risk Drinking on Changes in Health and Health-Related Quality of Life Among Older Adults: The Project SHARE Study

BACKGROUND

At-risk drinking, defined as alcohol use that is excessive or potentially harmful in combination with select comorbidities or medications, affects about 10% of older adults in the United States and is associated with higher mortality. The Project SHARE intervention, which uses patient and provider educational materials, physician counseling, and health educator support, was designed to reduce at-risk drinking among this vulnerable population. Although an earlier study showed that this intervention was successful in reducing rates of at-risk drinking, it is unknown whether these reductions translate into improved health and health-related quality of life (HRQL).

OBJECTIVE

The aim of this study was to examine changes in health and HRQL of older adult at-risk drinkers resulting from a patient-provider educational intervention.

RESEARCH DESIGN

A randomized controlled trial to compare the health and HRQL outcomes of patients assigned to the Project SHARE intervention vs. care as usual at baseline, 6- and 12-months post assignment. Control patients received usual care, which may or may not have included alcohol counseling. Intervention group patients received a personalized patient report, educational materials on alcohol and aging, a brief provider intervention, and a telephone health educator intervention.

SUBJECTS

Current drinkers 60years and older accessing primary care clinics around Santa Barbara, California (N=1049).

MEASUREMENTS

Data were collected from patients using baseline, 6- and 12-month mail surveys. Health and HRQL measures included mental and physical component scores (MCS and PCS) based on the Short Form-12v2 (SF-12v2), the SF-6D, which is also based on the SF-12, and the Geriatric Depression Scale (GDS). Adjusted associations of treatment assignment with these outcomes were estimated using generalized least squares regressions with random provider effects. Regressions controlled for age group, sex, race/ethnicity, marital status, education, household income, home ownership and the baseline value of the dependent variable.

RESULTS

After regression adjustment, the intervention was associated with a 0.58 point (95% CI: -0.06, 1.21) increase in 6-month MCS and a 0.14 point (95% CI: 0.01, 0.26) improvement in 12-month GDS score, compared to the control group. The intervention also increased adjusted SF-6D scores by 0.01 points at both 6 and 12months (6-month 95% CI: 0.01, 0.02; 12-month 95% CI: 0.01, 0.01).

CONCLUSIONS

Despite the previously shown effectiveness of the Project SHARE intervention to reduce at-risk drinking among older adults, this effect translated into effects on health and HRQL that were statistically but not necessarily clinically significant. Effects were most prominent for patients who received physician discussions, suggesting that provider counseling may be a critical component of primary care-based interventions targeting at-risk alcohol use.

Examining the Impact of Separate Components of a Multicomponent Intervention Designed to Reduce At-Risk Drinking Among Older Adults: The Project SHARE Study

BACKGROUND

Health promotion interventions often include multiple components and several patient contacts. The objective of this study was to examine how participation within a multicomponent intervention (Project SHARE) is associated with changes in at-risk drinking among older adults.

METHODS

We analyzed observational data from a cluster-randomized trial of 31 primary care physicians and their patients aged ≥60 years, at a community-based practice with 7 clinics. Recruitment occurred between 2005 and 2007. At-risk drinkers in a particular physician's practice were randomly assigned as a group to usual care (n = 640 patients) versus intervention (n = 546 patients). The intervention included personalized reports, educational materials, drinking diaries, in-person physician advice, and telephone counseling by health educators (HEs). The primary outcome was at-risk drinking at follow-up, defined by scores on the Comorbidity Alcohol Risk Evaluation Tool (CARET). Predictors included whether a physician-patient alcohol risk discussion occurred, HE call occurred, drinking agreement with the HE was made, and patients self-reported keeping a drinking diary as suggested by the HE.

RESULTS

At 6 months, there was no association of at-risk drinking with having had a physician-patient discussion. Compared to having had no HE call, the odds of at-risk drinking at 6 months were lower if an agreement was made or patients reported keeping a diary (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.37 to 0.90), or if an agreement was made and patients reported keeping a diary (OR 0.52, CI 0.28 to 0.97). At 12 months, a physician-patient discussion (OR 0.61, CI 0.38 to 0.98) or an agreement and reported use of a diary (OR 0.45, CI 0.25) were associated with lower odds of at-risk drinking.

CONCLUSIONS

Within the Project SHARE intervention, discussing alcohol risk with a physician, making a drinking agreement, and/or self-reporting the use of a drinking diary were associated with lower odds of at-risk drinking at follow-up. Future studies targeting at-risk drinking among older adults should consider incorporating both intervention components.

Disparities in receipt of specialty services among children with mental health need enrolled in the CMHI

OBJECTIVE

The study assessed racial-ethnic differences in receipt of mental health services among children enrolled in systems of care under the Children's Mental Health Initiative (CMHI).

METHODS

Survey data for 3,920 CMHI enrollees were used to estimate the association between race-ethnicity and the number of days in the 12 months postenrollment during which the child received individual psychotherapy, family and group psychotherapy, medication monitoring, assessment and evaluation, case management, residential treatment, and inpatient care. Two-part regressions with fixed site effects were estimated to adjust for geography and baseline population differences, including child and caregiver characteristics.

RESULTS

Compared with white non-Latino children, African Americans had lower odds of using any individual psychotherapy (odds ratio [OR]=.73, p=.019), family and group psychotherapy (OR=.79, p=.043), and medication monitoring (OR=.51, p<.001); among users of each service, African Americans had lower utilization of individual psychotherapy (incidence rate ratio [IRR]=.79, p<.001), family and group psychotherapy (IRR=.86, p=.011), and inpatient care (IRR=.75, p=.026). Latino children had lower odds of receiving medication monitoring (OR=.70, p=.007) and assessment and evaluation services (OR=.75, p=.027); among users, Latinos had lower utilization of individual (IRR=.91, p=.044) and family and group (IRR=.88, p=.044) psychotherapy. Pacific Islanders who received medication monitoring used services at a lower rate (IRR=.60, p=.009) than white children. No other associations with race-ethnicity were significant.

CONCLUSIONS

Racial-ethnic disparities in children's mental health treatment persist within systems of care. Further work is necessary to understand the role of individual program components, their interactions with community characteristics, and how they might affect mental health services use.

Patterns of prescription drug expenditures and medication adherence among medicare part D beneficiaries with and without the low-income supplement

BACKGROUND

The association between the Medicare Part D low-income subsidy (LIS), gap coverage, and outcomes such as medical expenditures, prescription fills, and medication adherence is not well understood. The purpose of this study was to examine the relationship between the LIS and these measures for patients within a large, national Part D plan in the United States.

METHODS

In this cross-sectional, retrospective analysis, we compared total and plan expenditures, out-of-pocket costs, and medication fills and adherence for three categories of Medicare beneficiaries: non-LIS beneficiaries without gap coverage (non-LIS/non-GC), non-LIS beneficiaries with gap coverage (non-LIS/GC), and LIS beneficiaries (LIS).

RESULTS

LIS beneficiaries, relative to non-LIS/non-GC and non-LIS/GC beneficiaries, had higher total expenditures ($1,887 vs. $1,360 vs. $1,341); lower out-of-pocket costs ($148 vs. $546 vs. $570); more expenditures exceeding the gap threshold (27.6% vs. 18.4% vs. 16.9%); and slightly higher adherence to blood pressure (65.6% vs. 64.2% vs. 62.4%); diabetes (62.5% vs. 57.7 vs. 57.4%); and lipid-lowering (59.6% vs. 57.0 vs. 55.6%) medications.

CONCLUSION

LIS beneficiaries had higher total expenditures, lower out-of-pocket costs, and modestly better adherence to diabetes medications than non-LIS/non-GC and non-LIS/GC beneficiaries.

The effect of an educational intervention on alcohol consumption, at-risk drinking, and health care utilization in older adults: the Project SHARE study

OBJECTIVE

The purpose of this study was to examine the effectiveness of a patient-provider educational intervention in reducing at-risk drinking among older adults.

METHOD

This was a cluster-randomized controlled trial of 31 primary care providers and their patients ages 60 years and older at a community-based practice with seven clinics. Recruitment occurred from July 2005 to August 2007. Eligibility was determined by telephone and a baseline mailed survey. A total of 1,186 at-risk drinkers were identified by the Comorbidity Alcohol Risk Evaluation Tool. Follow-up patient surveys were administered at 3, 6, and 12 months after baseline. Study physicians and their patients were randomly assigned to usual care (n = 640 patients) versus the Project SHARE (Senior Health and Alcohol Risk Education) intervention (n = 546 patients), which included personalized reports, educational materials, drinking diaries, physician advice during office visits, and telephone counseling delivered by a health educator. Main outcomes were alcohol consumption, at-risk drinking (overall and by type), alcohol discussions with physicians, health care utilization, and screening and intervention costs.

RESULTS

At 12 months, the intervention was significantly associated with an increase in alcohol-related discussions with physicians (23% vs. 13%; p ≤ .01) and reductions in at-risk drinking (56% vs. 67%; p ≤ .01), alcohol consumption (-2.19 drinks per week; p ≤ .01), physician visits (-1.14 visits; p = .03), emergency department visits (16% vs. 25%; p ≤ .01), and nonprofessional caregiving visits (12% vs. 17%; p ≤ .01). Average variable costs per patient were $31 for screening and $79 for intervention.

CONCLUSIONS

The intervention reduced alcohol consumption and at-risk drinking among older adults. Effects were sustained over a year and may have been associated with lower health care utilization, offsetting screening and intervention costs.

The impact of continuous Medicaid enrollment on diagnosis, treatment, and survival in six surgical cancers

OBJECTIVE

To examine the effect of Medicaid enrollment on the diagnosis, treatment, and survival of six surgically relevant cancers among poor and underserved Californians.

DATA SOURCES

California Cancer Registry (CCR), California's Patient Discharge Database (PDD), and state Medicaid enrollment files between 2002 and 2008.

STUDY DESIGN

We linked clinical and administrative records to differentiate patients continuously enrolled in Medicaid from those receiving coverage at the time of their cancer diagnosis. We developed multivariate logistic regression models to predict death within 1 year for each cancer after controlling for sociodemographic and clinical variables.

DATA COLLECTION/EXTRACTION METHODS

All incident cases of six cancers (colon, esophageal, lung, pancreas, stomach, and ovarian) were identified from CCR. CCR records were linked to hospitalizations (PDD) and monthly Medicaid enrollment.

PRINCIPAL FINDINGS

Continuous enrollment in Medicaid for at least 6 months prior to diagnosis improves survival in three surgically relevant cancers. Discontinuous Medicaid patients have higher stage tumors, undergo fewer definitive operations, and are more likely to die even after risk adjustment.

CONCLUSIONS

Expansion of continuous insurance coverage under the Affordable Care Act is likely to improve both access and clinical outcomes for cancer patients in California.

12-month outcomes of community engagement versus technical assistance to implement depression collaborative care: a partnered, cluster, randomized, comparative effectiveness trial

BACKGROUND

Depression collaborative care implementation using community engagement and planning (CEP) across programs improves 6-month client outcomes in minority communities, compared with technical assistance to individual programs (resources for services [RS]). However, 12-month outcomes are unknown.

OBJECTIVE

To compare effects of CEP and RS on mental health-related quality of life (MHRQL) and use of services among depressed clients at 12 months.

DESIGN

Matched health and community programs (n = 93) in 2 communities randomly assigned to receive CEP or RS. (ClinicalTrials.gov: NCT01699789).

MEASUREMENTS

Self-reported MHRQL and services use at baseline, 6 months, and 12 months.

SETTING

Los Angeles, California.

PATIENTS

1018 adults with depressive symptoms (8-item Patient Health Questionnaire score ≥10), 88% of whom were an ethnic minority.

INTERVENTION

CEP and RS to implement depression collaborative care.

MEASUREMENTS

The primary outcome was poor MHRQL (12-item mental health composite score ≤40) at baseline, 6 months, and 12 months; the secondary outcome was use of services at 12 months.

RESULTS

At 6 months, the finding that CEP outperformed RS to reduce poor MHRQL was significant but sensitive to underlying statistical assumptions. At 12 months, some analyses suggested that CEP was advantageous to MHRQL, whereas others did not confirm a significant difference favoring CEP. The finding that CEP reduced behavioral health hospitalizations at 6 months was less evident at 12 months and was sensitive to underlying statistical assumptions. Other services use did not significantly differ between interventions at 12 months.

LIMITATION

Data are self-reported, and findings are sensitive to modeling assumptions.

CONCLUSION

In contrast to 6-month results, no consistent effects of CEP on reducing the likelihood of poor MHRQL and behavioral health hospitalizations were found at 12 months. Still, given the needs of underresourced communities, the favorable profile of CEP, and the lack of evidence-based alternatives, CEP remains a viable strategy for policymakers and communities to consider.

Full-service partnerships among adults with serious mental illness in California: impact on utilization and costs

OBJECTIVE

California's full-service partnerships (FSPs) provide a combination of subsidized permanent housing and multidisciplinary team-based services with a focus on rehabilitation and recovery. The goal of the study was to examine whether participation in FSPs is associated with changes in health service use and costs compared with usual care.

METHODS

A quasi-experimental, pre-post, intent-to-treat design with a propensity score-matched contemporaneous control group was used to compare health service use and costs among 10,231 FSP clients and 10,231 matched clients with serious mental illness who were receiving public mental health services in California from January 1, 2004, through June 30, 2010.

RESULTS

Among FSP participants, the mean annual number of mental health outpatient visits increased by 55.5, and annual mental health costs increased by $11,725 relative to the matched control group. Total service costs increased by $12,056.

CONCLUSIONS

Participation in an FSP was associated with increases in outpatient visits and their associated costs. As supportive housing programs are implemented nationally and on a large scale, these programs will likely need to be more effectively designed and targeted in order to achieve reductions in costly inpatient services.

Optimizing enrollment in employer health programs: a comparison of enrollment strategies in the Diabetes Health Plan

BACKGROUND

Many health programs struggle with low enrollment rates.

OBJECTIVES

To compare the characteristics of populations enrolled in a new health plan when employer groups implement voluntary versus automatic enrollment approaches.

STUDY DESIGN

We analyzed enrollment rates resulting from 2 different strategies: voluntary and automatic enrollment. We used regression modeling to estimate the associations of patient characteristics with the probability of enrolling within each strategy. The subjects were 5014 eligible employees from 11 self-insured employers who had purchased the Diabetes Health Plan (DHP), which offers free or discounted copayments for diabetes related medications, testing supplies, and physician visits. Six employers used voluntary enrollment while 5 used automatic enrollment. The main outcome of interest was enrollment into the DHP. Predictors were gender, age, race/ethnicity, dependent status, household income, education level, number of comorbidities, and employer group.

RESULTS

Overall, the proportion of eligible members who were enrolled within the automatic enrollment strategy was 91%, compared with 35% for voluntary enrollment. Income was a significant predictor for voluntary enrollment but not for automatic enrollment. Within automatic enrollment, covered dependents, Hispanics, and persons with 1 nondiabetes comorbidity were more likely to enroll than other subgroups. Employer group was also a significant correlate of enrollment. Notably, all demographic groups had higher DHP enrollment rates under automatic enrollment than under voluntary enrollment.

CONCLUSIONS

For employer-based programs that struggle with low enrollment rates, especially among certain employee subgroups, an automatic enrollment strategy may not only increase the total number of enrollees but may also decrease some enrollment disparities.

Depression and all-cause mortality in persons with diabetes mellitus: are older adults at higher risk? Results from the Translating Research Into Action for Diabetes Study

OBJECTIVES

To compare the strength of the association between depression and mortality between elderly and younger individuals with diabetes mellitus.

DESIGN

A survival analysis conducted in a longitudinal cohort study of persons with diabetes mellitus to test the association between depression and mortality in older (≥ 65) and younger (18-65) adults.

SETTING

Managed care.

PARTICIPANTS

Persons aged 18 and older with diabetes mellitus who participated in the Wave 2 survey of the Translating Research Into Action for Diabetes (TRIAD) Study (N = 3,341).

MEASUREMENTS

The primary outcome was mortality risk, which was measured as days until death using linked data from the National Death Index. Depression was measured using the Patient Health Questionnaire.

RESULTS

After controlling for age, sex, race and ethnicity, income, and other comorbidities, mortality risk in persons with diabetes mellitus was 49% higher in those with depression than in those without, although results varied according to age. After controlling for the same variables, mortality risk in persons aged 65 and older with depression was 78% greater than in those without. For those younger than 65, the effect of depression on mortality was smaller and not statistically significant.

CONCLUSION

This analysis suggests that the effect of depression on mortality in persons with diabetes mellitus is most significant for older adults. Because there is evidence in the literature that treatment of depression in elderly adults can lead to lower mortality, these results may suggest that older adults with diabetes mellitus should be considered a high-priority population for depression screening and treatment.

At-risk drinking and outpatient healthcare expenditures in older adults

OBJECTIVES

To compare 12-month outpatient healthcare expenditures of at-risk and not-at-risk drinkers aged 60 and older.

DESIGN

Secondary analysis of data from Project Senior Health and Alcohol Risk Education, a cluster, randomized trial to test the efficacy of an intervention to reduce at-risk drinking.

SETTING

Seven primary care clinics in or near Santa Barbara, California.

PARTICIPANTS

Current drinkers aged 60 and older who completed a baseline survey (N = 2,779) and did not receive the study intervention, including 628 at-risk drinkers and 2,151 not-at-risk drinkers.

MEASUREMENTS

Comparisons of at-risk and not-at-risk drinkers for baseline demographic characteristics, health indicators, alcohol consumption, and adjusted and unadjusted outpatient healthcare expenditures incurred over 12 months after baseline.

RESULTS

At-risk drinkers were younger, more often male, and more likely to be married and had higher education and incomes than not-at-risk drinkers. Unadjusted 12-month mean outpatient healthcare expenditures were $1,333 ± 2,973 for at-risk drinkers and $1,417 ± 2,952 for the not-at-risk drinkers. There were no statistically significant differences in expenditures between groups before and after controlling for sociodemographic and health characteristics.

CONCLUSION

In this short-term study, no adjusted differences in healthcare expenditures were observed between at-risk and not-at-risk older drinkers. Future study is warranted to determine the role of at-risk drinking in long-term healthcare expenditures in older adults.

Personality disorders and body weight

We examine the impact of Axis II personality disorders (PDs) on body weight. PDs are psychiatric conditions that develop early in life from a mixture of genetics and environment, are persistent, and lead to substantial dysfunction for the affected individual. The defining characteristics of PDs conceptually link them with body weight, but the direction of the relationship likely varies across PD type. To investigate these links, we analyze data from Wave II of the National Epidemiological Survey of Alcohol and Related Conditions. We measure body weight with the body mass index (BMI) and a dichotomous indicator for obesity (BMI≥30). We find that women with PDs have significantly higher BMI and are more likely to be obese than otherwise similar women. We find few statistically significant or economically meaningful effects for men. Paranoid, schizotypal, and avoidant PDs demonstrate the strongest adverse impacts on women's body weight while dependent PD may be protective against elevated body weight among men. Findings from unconditional quantile regressions demonstrate a positive gradient between PDs and BMI in that the effects are greater for higher BMI respondents.

The quality of supportive cancer care in the veterans affairs health system and targets for improvement

IMPORTANCE

Characterizing the quality of supportive cancer care can guide quality improvement.

OBJECTIVE

To evaluate nonhospice supportive cancer care comprehensively in a national sample of veterans.

DESIGN, SETTING, AND PARTICIPANTS

Using a retrospective cohort study design, we measured evidence-based cancer care processes using previously validated indicators of care quality in patients with advanced cancer, addressing pain, nonpain symptoms, and information and care planning among 719 veterans with a 2008 Veterans Affairs Central Cancer Registry diagnosis of stage IV colorectal (37.0%), pancreatic (29.8%), or lung (33.2%) cancer.

MAIN OUTCOMES AND MEASURES

We abstracted medical records from diagnosis for 3 years or until death among eligible veterans (lived ≥ 30 days following diagnosis with ≥ 1 Veterans Affairs hospitalization or ≥ 2 Veterans Affairs outpatient visits). Each indicator identified a clinical scenario and an appropriate action. For each indicator for which a veteran was eligible, we determined whether appropriate care was provided. We also determined patient-level quality overall and by pain, nonpain symptoms, and information and care planning domains.

RESULTS

Most veterans were older (mean age, 66.2 years), male (97.2%), and white (74.3%). Eighty-five percent received both inpatient and outpatient care, and 92.5% died. Overall, the 719 veterans triggered a mean of 11.7 quality indicators (range, 1-22) and received a mean 49.5% of appropriate care. Notable gaps in care were that inpatient pain screening was common (96.5%) but lacking for outpatients (58.1%). With opioids, bowel prophylaxis occurred for only 52.2% of outpatients and 70.5% of inpatients. Few patients had a timely dyspnea evaluation (15.8%) or treatment (10.8%). Outpatient assessment of fatigue occurred for 31.3%. Of patients at high risk for diarrhea from chemotherapy, 24.2% were offered appropriate antidiarrheals. Only 17.7% of veterans had goals of care addressed in the month after a diagnosis of advanced cancer, and 63.7% had timely discussion of goals following intensive care unit admission. Most decedents (86.4%) were referred to palliative care or hospice before death. Single- vs multiple-fraction radiotherapy should have been considered in 28 veterans with bone metastasis, but none were offered this option.

CONCLUSIONS AND RELEVANCE

These care gaps reflect important targets for improving the patient and family experience of cancer care.

Mental health and risky sexual behaviors: evidence from DSM-IV Axis II disorders

BACKGROUND

Several economic studies link poor mental health and substance misuse with risky sexual behaviors. However, none have examined the relationships between DSM-IV Axis II mental health disorders (A2s) and risky sexual behaviors. A2 disorders are a poorly understood, yet prevalent and disabling class of mental health conditions. They develop early in life through an interaction of genetics and environment, and are persistent across the life course. Common features include poor impulse control, addiction, social isolation, and elevated sexual desires, although the defining features vary substantially across disorder.

AIMS OF THE STUDY

To investigate the association between A2 disorders and three measures of risky sexual behavior.

METHODS

We obtain data on adults age 20 to 50 years from Wave II of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC). Our outcome measures include early initiation into sexual activity, and past year regular use of alcohol before sex and sexually transmitted disease diagnosis. NESARC administrators use the Alcohol Use Disorder and Associated Disabilities Interview Schedule to classify respondents as meeting criteria for the ten A2 disorders recognized by the American Psychiatric Association. We construct several measures of A2 disorders based on the NESARC administrators' classifications. Given their comorbidity with A2 disorders, we explore the importance of Axis I disorders in the estimated associations.

RESULTS

We find that A2 disorders are generally associated with an increase in the probability of risky sexual behaviors among both men and women. In specifications that disaggregate disorders into clusters and specific conditions, the significant associations are not uniform, but are broadly consistent with the defining features of the cluster or disorder. Inclusion of A1 disorders attenuates estimated associations for some risky sexual behaviors among men, but not for women.

DISCUSSION

We find positive associations between A2 disorders and our measures of risky sexual behaviors. Our findings are subject to several data limitations, however. The NESARC lacks information on more advanced risky sexual behaviors and our measure of early initiation into sexual activity is retrospective. Identifying the causal effects of mental health and risky sexual behaviors is complicated due to bias from reverse causality and omitted variables. We believe these sources of bias are less of a concern in our study, however. Specifically, A2 disorders develop early in life and pre-date the risky sexual behaviors, thus negating reverse causality. Because the NESARC contains a rich set of personal characteristics, we are also able to minimize potential omitted variable bias.

IMPLICATIONS FOR HEALTH CARE PROVISION AND USE

A2 disorders are significantly associated with risky sexual behaviors, which could lead to greater utilization and cost of health care services.

IMPLICATION FOR HEALTH POLICIES

Health care providers should consider A2 disorders when developing health promotion recommendations as these disorders may place individuals at elevated risk for unsafe sexual behaviors.

IMPLICATIONS FOR FURTHER RESEARCH

Future studies should examine the causal mechanisms between A2 disorders and risky sexual behaviors.

Mental health and high-cost health care utilization: new evidence from Axis II disorders

OBJECTIVE

To analyze the associations between Axis II (A2) disorders and two measures of health care utilization with relatively high cost: emergency department (ED) episodes and hospital admissions.

DATA SOURCE/STUDY SETTING

Wave I (2001/2002) and Wave II (2004/2005) of the National Longitudinal Survey on Alcohol and Related Conditions (NESARC).

STUDY DESIGN

A national probability sample of adults. Gender-stratified regression analysis adjusted for a range of covariates associated with health care utilization.

DATA COLLECTION

The target population of the NESARC is the civilian noninstitutionalized population aged 18 years and older residing in the United States. The cumulative survey response rate is 70.2 percent with a response rate of 81 percent (N=43,093) in Wave I and 86.7 percent (N=34,653) in Wave II.

PRINCIPAL FINDINGS

Both men and women with A2 disorders are at elevated risk for ED episodes and hospital admissions. Associations are robust after adjusting for a rich set of confounding factors, including Axis I (clinical) psychiatric disorders. We find evidence of a dose-response relationship, while antisocial and borderline disorders exhibit the strongest associations with both measures of health care utilization.

CONCLUSIONS

This study provides the first published estimates of the associations between A2 disorders and high-cost health care utilization in a large, nationally representative survey. The findings underscore the potential implications of these disorders on health care expenditures.

Regional variation in acute care length of stay after orthopaedic surgery total joint replacement surgery and hip fracture surgery

OBJECTIVE

To examine change in regional variations in acute care length of stay (LOS) after orthopedic surgery following expiration of the New York (NY) State exemption to the Prospective Payment System and implementation of the Medicare Short Stay Transfer Policy.

METHODS

Time series analyses were conducted to evaluate change in LOS across regions after policy implementations. Small area analyses were conducted to examine residual variation in LOS. The dataset included A 100% sample of fee-for-service Medicare patients undergoing surgical repair for hip fracture or elective joint replacement surgery between 1996 and 2001. Data files from Centers for Medicare and Medicaid Services 1996-2001 Medicare Provider Analysis and Review file, 1999 Provider of Service file, and data from the 2000 United States Census were used for analysis.

RESULTS

In 1996, LOS in NY after orthopedic procedures was much longer than the remainder of the country. After policy changes, LOS fell. However, significant residual variation in LOS persisted. This residual variation was likely partly explained by differences variation in regional managed care market penetration, patient management practices and unmeasured characteristics associated with the hospital location.

CONCLUSIONS

NY hospitals responded to changes in reimbursement policy, reducing variation in LOS. However, even after 5 years of financial pressure to constrain costs, other factors still have a strong impact on delivery of patient care.

Medical costs associated with type 2 diabetes complications and comorbidities

OBJECTIVES

To estimate the direct medical costs associated with type 2 diabetes, its complications, and its comorbidities among U.S. managed care patients.

STUDY DESIGN

Data were from patient surveys, chart reviews, and health insurance claims for 7109 people with type 2 diabetes from 8 health plans participating in the Translating Research Into Action for Diabetes (TRIAD) study between 1999 and 2002.

METHODS

A generalized linear regression model was developed to estimate the association of patients' demographic characteristics, tobacco use status, treatments, related complications, and comorbidities with medical costs.

RESULTS

The mean annualized direct medical cost was $2465 for a white man with type 2 diabetes who had been diagnosed fewer than 15 years earlier, was treated with oral medication or diet alone, and had no complications or comorbidities. We found annualized medical costs to be 10% to 50% higher for women and for patients whose diabetes had been diagnosed 15 or more years earlier, who used tobacco, who were being treated with insulin, or who had several other complications. Coronary heart disease, congestive heart failure, hemiplegia, and amputation were each associated with 70% to 150% higher costs. Costs were approximately 300% higher for end-stage renal disease treated with dialysis and approximately 500% higher for end-stage renal disease with kidney transplantation.

CONCLUSIONS

Most medical costs incurred by patients with type 2 diabetes are related to complications and comorbidities. Our cost estimates can help when determining the most cost-effective interventions to prevent complications and comorbidities.

Cost-related nonadherence by medication type among Medicare Part D beneficiaries with diabetes

BACKGROUND

Despite the rollout of Medicare Part D, cost-related nonadherence (CRN) among older adults remains a problem.

OBJECTIVES

To examine the rate and correlates of self-reported CRN among a population of older persons with diabetes.

RESEARCH DESIGN

Cross-sectional.

SUBJECTS

A total of 1264 Part D patients with diabetes, who entered the coverage gap in 2006.

MEASURES

Initial administrative medication lists were verified in computer-assisted telephone interviews, in which participants brought their medication bottles to the phone. Medications were classified into cardiometabolic (diabetes, hypertension, cholesterol-lowering), symptom relief, and "other." Participants were asked if they had any CRN during 2006, and if so to which medication/s. We used the person-medication dyad as the unit of analysis, and tested a multivariate random effects logistic regression model to analyze the correlates of CRN.

RESULTS

Approximately 16% of participants reported CRN. CRN was more frequent for cholesterol-lowering medications (relative risk, 1.54; 95% confidence interval, 1.01-2.32) compared with medications taken for symptom relief. CRN was reported less frequently with increasing age above 75 years, compared with patients between 65 and 69. In addition, compared with those with incomes of ≥$40,000, CRN risk for those with incomes of <$25,000 was markedly higher (relative risk, 3.05; 95% confidence interval, 1.99-4.65).

CONCLUSIONS

In summary, we found high rates of CRN among Medicare beneficiaries with diabetes, particularly those with lower incomes. We observed more frequent CRN for cholesterol-lowering medications as compared with medications for symptom relief. Efforts to ensure medication affordability for this population will be important in boosting adherence to key medications.

Medicare Part D benzodiazepine exclusion and use of psychotropic medication by patients with new anxiety disorders

OBJECTIVE

The Medicare Modernization Act (MMA) specifically excluded benzodiazepines from Medicare Part D coverage starting in 2006; however, benzodiazepines are an effective, low-cost treatment for anxiety. This study evaluated the effect of the Medicare Part D benzodiazepine coverage exclusion among patients with new anxiety disorders.

METHODS

The authors used a quasi-experimental cohort design to study patients with new anxiety diagnoses from a large national health plan during the first six months of 2005, 2006, and 2007. Logistic and zero-truncated negative-binomial regression models using covered claims for behavioral, medical, and pharmaceutical care linked with eligibility files were used to estimate utilization and costs of psychotropic medication and health care utilization among elderly Medicare Advantage enrollees (N=8,397) subject to the MMA benzodiazepine exclusion and a comparison group of near-elderly (ages 60–64) enrollees (N=1,657) of a managed care plan.

RESULTS

Medicare Advantage enrollees diagnosed in 2005 had significantly (p<.05) higher rates of covered claims for benzodiazepines and all psychotropic drugs, lower rates of covered claims for nonbenzodiazepines, and lower expenditures for psychotropic drugs than enrollees diagnosed in 2006 and 2007. There were no significant differences over time in utilization or expenditures related to psychotropic medication among the comparison group. There also were no significant changes over time in outpatient visits for behavioral care by either cohort.

CONCLUSIONS

Among elderly patients with new anxiety diagnoses, the MMA benzodiazepine exclusion increased use of nonbenzodiazepine psychotropic drugs without substitution of increased behavioral care. Overall, the exclusion was associated with a modest increase in covered claims for psychotropic medication.

Disability and decline in physical function associated with hospital use at end of life

BACKGROUND

Hospital use near the end of life is often undesirable to patients, represents considerable Medicare cost, and varies widely across regions.

OBJECTIVE

To concurrently examine regional and patient factors, including disability and functional decline, associated with end-of-life hospital use.

DESIGN/PARTICIPANTS

We sampled decedents aged 65 and older (n = 2,493) from the Health and Retirement Study (2000-2006), and linked data from individual Medicare claims and the Dartmouth Atlas of Health Care. Two-part regression models estimated the relationship between total hospital days in the last 6 months and patient characteristics including physical function, while adjusting for regional resources and hospital care intensity (HCI).

KEY RESULTS

Median hospital days was 7 (range = 0-183). 53% of respondents had functional decline. Compared with decedents without functional decline, those with severe disability or decline had more regression-adjusted hospital days (range 3.47-9.05, depending on category). Dementia was associated with fewer days (-3.02); while chronic kidney disease (2.37), diabetes (2.40), stroke or transient ischemic attack (2.11), and congestive heart failure (1.74) were associated with more days. African Americans and Hispanics had more days (5.91 and 4.61, respectively). Those with family nearby had 1.62 fewer days and hospice enrollees had 1.88 fewer days. Additional hospital days were associated with urban residence (1.74) and residence in a region with more specialists (1.97) and higher HCI (2.27).

CONCLUSIONS

Functional decline is significantly associated with end-of-life hospital use among older adults. To improve care and reduce costs, health care programs and policies should address specific needs of patients with functional decline and disability.

Effect of medicare part D benzodiazepine exclusion on psychotropic use in benzodiazepine users

OBJECTIVES

To evaluate the effect of the Medicare benzodiazepine coverage exclusion on psychotropic use of benzodiazepine users.

DESIGN

Pre-post design with concurrent control group.

SETTING

General community.

PARTICIPANTS

Intervention and comparison cohorts of individuals drawn from the same insurer who were prescribed benzodiazepines through the end of 2005. Intervention participants (n = 19,339) were elderly adults from a large, national Medicare Advantage plan subject to benzodiazepine exclusion as a result of the Medicare Modernization Act (MMA). Comparison participants (n = 3,488) were near-elderly individuals enrolled in a managed care plan not subject to the MMA benzodiazepine exclusion.

MEASUREMENTS

Any psychotropic drug use and expenditures.

RESULTS

In the intervention cohort, benzodiazepine use and expenditures significantly declined from 100% and $134 in 2005 to 74.8% and $59, respectively, in 2007. Nonbenzodiazepine psychotropic drug use and expenditures significantly increased from 35.8% and $163 in 2005 to 39.5% and $207, respectively, in 2007. In the comparison cohort, benzodiazepine use and expenditures also significantly declined from 100% and $173 in 2005 to 57.5% and $105, respectively, in 2007, but nonbenzodiazepine psychotropic drug use and expenditures significantly declined from 55.4% and $647 in 2005 to 45.1% and $572, respectively, in 2007. Changes in antidepressant and anxiolytic use were the primary cause of changes in nonbenzodiazepine psychotropic drugs in both cohorts.

CONCLUSION

Use of benzodiazepines continued in elderly adults despite negative financial incentives, possibly because of the low costs of such medications. Although some substitution occurred with antidepressants and anxiolytics, the magnitude of this increase did not fully offset the reduction in benzodiazepine use.

Medicaid expenditures on psychotropic medications for children in the child welfare system

OBJECTIVE

Children in the child welfare system are the most expensive child population to insure for their mental health needs. The objective of this article is to estimate the amount of Medicaid expenditures incurred from the purchase of psychotropic drugs - the primary drivers of mental health expenditures - for these children.

METHODS

We linked a subsample of children interviewed in the first nationally representative survey of children coming into contact with U.S. child welfare agencies, the National Survey of Child and Adolescent Well-Being (NSCAW), to their Medicaid claims files obtained from the Medicaid Analytic Extract. Our data consist of children living in 14 states, and Medicaid claims for 4 years, adjusted to 2010 dollars. We compared expenditures on psychotropic medications in the NSCAW sample to a propensity score-matched comparison sample obtained from Medicaid files.

RESULTS

Children surveyed in NSCAW had over thrice the odds of any psychotropic drug use than the comparison sample. Each maltreated child increased Medicaid expenditures by between $237 and $840 per year, relative to comparison children also receiving medications. Increased expenditures on antidepressants and amphetamine-like stimulants were the primary drivers of these increased expenditures. On average, an African American child in NSCAW received $399 less expenditure than a white child, controlling for behavioral problems and other child and regional characteristics. Children scoring in the clinical range of the Child Behavior Checklist received, on average, $853 increased expenditure on psychotropic drugs.

CONCLUSION

Each child with child welfare involvement is likely to incur upwards of $1482 in psychotropic medication expenditures throughout his or her enrollment in Medicaid. Medicaid agencies should focus their cost-containment strategies on antidepressants and amphetamine-type stimulants, and expand use of instruments such as the Child Behavior Checklist to identify high-cost children. Both of these strategies can assist Medicaid agencies to better predict and plan for these expenditures.

The Association of Depression and the Cardiovascular Risk Factors of Blood Pressure, HbA1c, and Body Mass Index among Patients with Diabetes: Results from the Translating Research into Action for Diabetes Study

Diabetic patients are nearly three times as likely to have depression as their nondiabetic counterparts. Patients with diabetes are already at risk for poor cardiovascular health. Using cross-sectional data from the translating research into action for diabetes (TRIAD) study, the authors tested the association of depression with cardiovascular risk factors in diabetic patients. Depression was measured using the patient health questionnaire (PHQ8). Patients who scored greater than 9 on the PHQ8 were classified as depressed and were compared with those who were not depressed (n = 2,341). Depressed patients did not have significantly different blood pressure levels than those who were not depressed. However, those who were depressed had higher HbA1c levels than those who were not depressed (P < 0.01) and higher BMIs than those who were not depressed (P < 0.01). These results indicate that depressed diabetic patients are at greater risk of having poor control of cardiovascular risk factors and suggest that depression screening should be a standard practice among this patient group.

Determinants of death in the hospital among older adults

OBJECTIVES

To investigate patient-level determinants of in-hospital death, adjusting for patient and regional characteristics.

DESIGN

Using multivariable regression, the relationship between in-hospital death and participants' social, functional, and health characteristics was investigated, controlling for regional Hospital Care Intensity Index (HCI) from the Dartmouth Atlas of Health Care.

SETTING

The Health and Retirement Study, a longitudinal nationally representative cohort of older adults.

PARTICIPANTS

People aged 67 and older who died between 2,000 and 2,006 (N = 3,539) were sampled.

MEASUREMENTS

In-hospital death.

RESULTS

Thirty-nine percent (n = 1,380) of participants died in the hospital (range 34% in Midwest to 45% in Northeast). Nursing home residence, functional dependence, and cancer or dementia diagnosis, among other characteristics, were associated with lower adjusted odds of in-hospital death. Being black or Hispanic, living alone, and having more medical comorbidities were associated with greater adjusted odds, as was higher HCI. Sex, education, net worth, and completion of an advance directive did not correlate with in-hospital death.

CONCLUSION

Black race, Hispanic ethnicity, and other functional and social characteristics are correlates of in-hospital death, even after controlling for the role of HCI. Further work must be done to determine whether preferences, provider characteristics and practice patterns, or differential access to medical and community services drive this difference.

Drug benefit changes under Medicare Advantage Part D: heterogeneous effects on pharmaceutical use and expenditures

BACKGROUND

Although Medicare Part D improved drug benefits for many beneficiaries, its impact on the coverage of Medicare Advantage Part D (MAPD) enrollees depended on their pre-existing benefits and whether they had gap coverage under Part D.

OBJECTIVE

To examine changes in prescription drug utilization and expenditures associated with drug benefit changes resulting from the implementation of Part D.

PATIENTS

We studied 248,773 continuously enrolled MAPD patients in eight states. Patients whose insurance product or Census block could not be identified or who had atypical benefits, low-income subsidies or Medicaid coverage were excluded.

MAIN MEASURES

The main outcomes were changes in prescription drug days supply and expenditures from 2005 to 2006 and 2005 to 2007.

DESIGN

We linked Census data with 2005-7 MAPD claims, encounter, enrollment, and benefits data and estimated associations of the outcomes with changes in drug benefits, controlling for 2005 comorbidities, demographics, and Census population characteristics.

KEY RESULTS

MAPD enrollees whose drug benefits became potentially less generous after Part D had the smallest increases in drug utilization and expenditures (e.g., drug expenditures increased by $130 between 2005 and 2006), while those who potentially gained the most from Part D experienced the largest increases ($302). The differences in benefit design changes had a stronger association with drug utilization and outcomes among patients at high risk of gap entry than among the entire sample.

CONCLUSIONS

Although Medicare Part D unambiguously improved drug coverage for many elderly, it led to heterogeneous changes in drug benefits among MAPD enrollees, who already had generic and sometimes branded drug benefits. After 2006, benefits were worse for individuals who had branded drug coverage in 2005 but now had a coverage gap, but benefits may have improved for individuals who acquired branded drug coverage. Commensurate with these differential changes in benefits following Part D, changes in drug utilization and expenditures varied substantially as well.
