Transition to Managed Care Impacts Health Care Service Utilization by Children Insured by Medicaid

Purpose. To evaluate the impact of transition to managed care from fee for service on asthma service utilization among Maryland Medicaid insured children. Methods. Healthcare claims from 1997–2000 for children with asthma insured by Maryland Medicaid were extracted and analyzed. Results. Between 1997–2000, inhaled corticosteroid use increased as a proportion of all asthma medications. Outpatient asthma visits increased from 4.2% to 5.9% of all outpatient claims as both asthma-related hospitalizations and emergency department visits decreased. Conclusions. Restructuring of Maryland Medicaid for children from fee for service to managed care was associated with improvement in asthma-related healthcare utilization claims.     

Treatment Regimens and Health Care Utilization in Children with Persistent Asthma Symptoms

This study evaluated the anti-inflammatory medication regimens in children with persistent asthma, determined their health care utilization patterns, and evaluated factors associated with failure to seek and/or receive appropriate treatment. Parents of 68% of children who qualified for anti-inflammatory medications by National Asthma Education and Prevention Program (NAEPP) guidelines reported their use. However, only 14% received an optimal regimen (mild intermittent symptoms), while 55% were still symptomatic despite reported medications (suboptimal regimen). Nearly half of symptomatic children did not have a health care visit; of those who did, 61% had no corrective action documented. Factors contributing to variations in regimen and utilization are discussed.

Gender Differences in Asthma Experience and Disease Care in a Managed Care Organization

The purpose of this study was to describe gender differences in asthma in a managed care organization. We collected data from a patient survey, electronic administrative data, and hard-copy chart reviews. Women reported significantly lower general health status, more symptoms and greater severity of asthma, more activity limitations, more use of asthma-relieving medications, and more acute visits for asthma than men. Conversely, women tended to report better asthma care measures. These gender disparities warrant further study to support appropriate adjustment of clinical care and health-care-related services for women.

The Impact of Managed Care on Health Care Utilization Among Adults with Asthma

Study Objectives. To compare kinds and amounts of health care used by adults with asthma in managed care and fee-for-service settings. Design. Cross-sectional structured telephone survey of Northern California adults with asthma from random samples of pulmonologists, allergist-immunologists, family practitioners, and from a random sample of the non-institutionalized population. Measurements. Validated measures of kind of health insurance plans, kinds and amounts of services used for asthma and other reasons, demographic characteristics, severity of asthma, comorbidity, and overall health and functional status. Results. Eighty one percent of the 416 adults with asthma studied were in some form of managed care (75% in HMOs and 6% in PPOs). Those in managed care (MC) and fee-for-service (FFS) did not differ substantively in the proportion with a regular source or principal provider of asthma care, with a peak flow meter or action plan, having received instructions in the use of an inhaler, reporting current use of inhaled beta-agonists, home nebulized beta-agonists, or inhaled steroids, or reporting ER visits or flu shots in the year prior to interview. Persons with asthma in MC reported significantly fewer total physician visits (after adjustment, 4.3 MC, 7.1 FFS, difference = 2.8, 95% CI - 5.4, - 0.1), principally because those in MC had many fewer visits to allergist-immunologists (after adjustment 4.9 MC, 21.4 FFS, difference = - 16.5, 95% CI - 27.8-5.3). The two groups did not differ significantly in the proportion with asthma-related or non asthma hospital admissions. Conclusions. Persons with asthma in fee-for-service settings reported a greater number of certain kinds of ambulatory visits, particularly visits to allergist-immunologists, for their asthma than those in managed care, but did not differ in the use of the hospital for their asthma and in non asthma care.     

Processes and Outcomes of Substance Abuse Treatment Between Two Programs for Clients Insured Under Managed Care

The purpose of this research (N = 160) was to describe and compare substance abuse treatment in two programs under managed care: one residential (RT) and one outpatient (OP). Clients in both settings improved significantly from before to after treatment in relation to substance use and quality of life. However, intensity of treatment (hours of care/week) was much greater in RT and days of sobriety were significantly higher after treatment in RT than in OP (p = .04). Intensity was negatively related to incidents of substance use during treatment (SUdT), which predicted substance use after treatment; SUdT averaged. 2 for RT, and 1.6 for OP (p = .0001). Importantly, treatment was completed by 74 patients (over 90%) from RT, with 8 dropping out, and 53 (almost 70%) of those in OP completed treatment while 25 dropped out. Intensity, as seen in the RT program, rather than duration, was more effective in substance use reduction and treatment completion.     

The Impact of Managed Care on Health Care Utilization Among Adults with Asthma

Study Objectives. To compare kinds and amounts of health care used by adults with asthma in managed care and fee‐for‐service settings. Design. Cross‐sectional structured telephone survey of Northern California adults with asthma from random samples of pulmonologists, allergist‐immunologists, family practitioners, and from a random sample of the non‐institutionalized population. Measurements. Validated measures of kind of health insurance plans, kinds and amounts of services used for asthma and other reasons, demographic characteristics, severity of asthma, comorbidity, and overall health and functional status. Results. Eighty one percent of the 416 adults with asthma studied were in some form of managed care (75% in HMOs and 6% in PPOs).

Persons with asthma in MC reported significantly fewer total physician visits (after adjustment, 4.3 MC, 7.1 FFS, difference = 2.8, 95% CI ? 5.4, ? 0.1), principally because those in MC had many fewer visits to allergist‐immunologists (after adjustment 4.9 MC, 21.4 FFS, difference = ? 16.5, 95% CI ? 27.8–5.3). The two groups did not differ significantly in the proportion with asthma‐related or non asthma hospital admissions. Conclusions. Persons with asthma in fee‐for‐service settings reported a greater number of certain kinds of ambulatory visits, particularly visits to allergist‐immunologists, for their asthma than those in managed care, but did not differ in the use of the hospital for their asthma and in non asthma care.     

Potentially inappropriate medication use by elderly persons in U.S. Health Maintenance Organizations, 2000-2001

OBJECTIVES: To determine rates of potentially inappropriate medication use in elderly persons in managed care plans in the United States in 2000-2001. DESIGN: Cross-sectional study using automated medication-dispensing data. SETTING: Ten geographically distributed health maintenance organizations (HMOs). PARTICIPANTS: One hundred fifty-seven thousand five hundred seventeen members aged 65 years and older enrolled in one of the HMOs. MEASUREMENTS: Prevalence of use of 33 potentially inappropriate medications from January 1, 2000 through June 30, 2001. RESULTS: In 2000-2001, 28.8% (95% confidence interval=28.6-29.1) of elderly individuals received at least one of 33 potentially inappropriate medications. This rate ranged from 23.0% to 36.5% across the 10 HMOs. Approximately 5% of elderly patients received at least one of the 11 medications classified by an expert panel as "always avoid," 13% received at least one of the eight medications that would rarely be considered appropriate, and 17% received at least one of the 14 medications that have some indications but are often misused. Overall, rates of use of these medications were greater in women (32.4%) than in men (24.2%). At least 1% of elderly members received belladonna alkaloids (2.3%), dicyclomine (1.1%), or hyoscyamine (1.2%), each of which multiple expert panels have classified as always inappropriate in patients aged 65 years and older. Seven percent of elderly members received propoxyphene, an analgesic medication considered rarely appropriate in the elderly and a drug that has a long history of limited efficacy and potential for toxicity. CONCLUSION: Recent rates of potentially inappropriate medication use by elderly HMO members were at least as great as in a 1996 national sample. This study highlights the need to understand more fully the rationale behind the continued use of these medications.     

Asthma Medication Use in School-Aged Children

Using data from the1996, 1998, and 2000 Medical Expenditure Panel Survey, this study assessed controller medication use in a national representative sample of school-aged children with persistent asthma. Children 5 to 17 years of age with persistent asthma were identified in accordance with the Health Employer Data and Information Set specifications. Nonuse of controllers and excess use of relievers were common. In addition, controller medications were significantly less likely to be purchased for younger children, black and Hispanic children, and white children whose mothers had at least a college education. Efforts to improve childhood asthma management are needed, especially for those children.

Latino Children with Asthma: Rates and Risks for Medical Care Utilization

Latino families have been reported to underutilize health care services compared with families from other ethnic backgrounds. As part of a community trial in a low income Latino population designed to decrease environmental tobacco smoke (ETS) exposure in children with asthma in San Diego, we examined unscheduled medical care for asthma. Latino families (N = 193) reported information about medical care use for their children during the past 12 months. About 23% were hospitalized, 45% used the emergency department, and 60% used urgent care services. About 8.5% of families had two or more hospitalizations in 12 months. Most families were insured by Medicaid or had no insurance. Significant risk factors for a child's hospitalization were age (under age six), failure to use a controller medication, and a parental report of the child's health status as being poor. Risk factors for emergency department use were age (under age six) and male gender. These findings indicate that low-income Latino families with young children with asthma lack the medical resources necessary for good asthma control. Quality and monitored health care with optimization of asthma management could reduce costly acute care services.     

Improving Pediatric Asthma Control Among Minority Children Participating in Medicaid: Providing Practice Redesign Support to Deliver a Chronic Care Model

Background. Asthma, a leading chronic disease of children, currently affects about 6.2 million (8.5%) children in the United States. Despite advances in asthma research and availability of increasingly effective therapy, many children do not receive appropriate medications to control the disease, have overreliance on reliever medication, and lack systematic follow-up care. The situation is even worse for poor inner-city and minority children who have significantly worse asthma rates, severity, and outcomes. National Asthma Education and Prevention Program Guidelines recommend a multimodal, chronic care approach. Objective. The authors assessed the effectiveness of practice redesign and computerized provider feedback in improving both practitioner adherence to National Asthma Education and Prevention Program Guidelines (NAEPP), and patient outcomes in 295 poor minority children across four Federally Qualified Health Centers (FQHC). Methods. In a nonrandomized, two-group (intervention versus comparison), two-phase trial, all sites were provided redesign support to provide quarterly well-asthma visits using structured visit forms, community health workers for outreach and follow-up, a Web-based disease registry for tracking and scheduling, and a provider education package. Intervention sites were given an additional Web-based, computerized patient-specific provider feedback system that produced a guideline-driven medication assessment prompt. Results. Logistic regression results showed that providers at intervention sites were more than twice as likely on average to prescribe guideline-appropriate medications after exposure to our feedback system during the Phase I enrollment period than providers at comparison sites (exp(B) = 2.351, confidence interval [CI] = 1.315–4.204). In Phase II (the postenrollment visit period), hierarchical linear models (HLMs) and latent growth curves were used to show that asthma control improved significantly by .19 (SE = .05) on average for each of the remaining four visits (about 11% of a standard deviation), and improved even more for patients at intervention sites. These results show that implementation of practice redesign support guided by a pediatric chronic care model can improve provider adherence to treatment guidelines as well as patients’ asthma control. Conclusions. The addition of patient-specific feedback for providers results in quicker adoption of guideline recommendations and potentially greater improvements in asthma control compared to the basic practice redesign support alone.     

Assessing the Service Linkages of Substance Abuse Agencies with Mental Health and Primary Care Organizations

Fragmentation of substance abuse treatment represents a major barrier to effective treatment for individuals with cooccurring substance abuse and mental and physical health disorders. Linkages of substance abuse treatment organizations with primary care and mental health agencies are widely considered to be a feasible way to integrate services. In this study, we analyzed information collected from a national sample of 62 outpatient substance abuse treatment units (OSATs) to understand the extent of services linkages in these organizations and to identify facilitators and barriers to service linkages. Results showed that OSATs had limited service linkages with primary care and mental health providers. The cited barriers to linkages included clients' financial problems, managed care restrictions, and limited organizational capacity. Onsite service provision was implemented in some OSATs. The pattern of service linkages in OSATs appeared to reflect the health needs of substance abuse clients.     

The Impact of Publicly Funded Managed Care on Adolescent Substance Abuse Treatment Outcomes

This study compares the 12-month changes in substance use following admission to substance abuse treatment in Massachusetts between adolescents enrolled in Medicaid managed care and other publicly funded adolescents. Two hundred and fifty-five adolescents were interviewed as they entered substance abuse treatment and at 6 and 12 month follow-ups. Medicaid enrollment data were used to determine the managed care enrollment status. One hundred forty two (56%) adolescents were in the managed care group and 113 (44%) comprise the comparison group. Substance use outcomes include a count of negative consequences of substance use, days of alcohol use, days of cannabis use, and days of any substance use in the previous 30 days. Repeated measures analysis of covariance (ANCOVA) was used to assess change with time of measurement and managed care status as main effects and the interaction of time and managed care included to measure differences between the groups over time. Although several changes across time were detected for all four outcomes, we found no evidence of an impact of managed care for any of the outcomes. The results of our study do not support the fears that behavioral managed care, by imposing limits on services provided, would substantially reduce the effectiveness of substance abuse treatment for adolescents. At the same time, the results do not support those who believe that the continuity of care and improved resource utilization claimed for managed care would improve outcomes.     

Patient Satisfaction with Budesonide Turbuhaler™ Versus Triamcinolone Acetonide Administered via Pressurized Metered-Dose Inhaler in a Managed Care Setting

Dissatisfaction with medication may negatively affect compliance and thus the effectiveness of the treatment. However, no prospective well-controlled studies have assessed the relative patient satisfaction with competing inhaled corticosteroids in a real-life setting. The objective of the current study was to compare the relative patient satisfaction with budesonide inhalation powder administered via Turbuhaler (AstraZeneca LP, Wilmington, DE) (200 to 1600 µg/d using one of 3 dosing strengths: 100, 200, or 400 µg per inhalation) and triamcinolone acetonide administered via pressurized metered-dose inhaler (200 to 1600 µg/d) among persons treated in managed care settings. A total of 945 subjects 18 years of age or older diagnosed with asthma and enrolled in 25 managed care organizations participated in this prospective, randomized, open-label, parallel-group, 12-month study. As part of the study, subjects completed a self-administered, 17-item patient satisfaction questionnaire that addressed 4 domains: side effects, knowledge/ease of use, convenience, and overall satisfaction. Questionnaire reliability was assessed using Cronbach's alpha, and validity was examined by correlating subscale scores with symptom-free days and Medical Outcomes Study 36-Item Short-Form questionnaire and Asthma Quality of Life Questionnaire scores. The satisfaction questionnaire also included a previously validated section addressing patient compliance. Patients receiving budesonide had significantly higher scores for all four satisfaction subscales throughout the study period than did those receiving triamcinolone acetonide. Similarly, compliance scores were consistently higher for the budesonide group. The difference between the treatment groups in overall satisfaction scores at the end of the study was clinically meaningful. Patients treated with budesonide were significantly more satisfied and compliant with their inhaled corticosteroid regimen compared with patients treated with triamcinolone acetonide.     

Limited Health Literacy is a Barrier to Medication Reconciliation in Ambulatory Care

Background Limited health literacy may influence patients’ ability to identify medications taken; a serious concern for ambulatory safety and quality. Objective To assess the relationship between health literacy, patient recall of antihypertensive medications, and reconciliation between patient self-report and the medical record. Design In-person interviews, literacy assessment, medical records abstraction. Participants Adults with hypertension at three community health centers. Measurement We measured health literacy using the short-form Test of Functional Health Literacy in Adults. Patients were asked about the medications they took for blood pressure. Their responses were compared with the medical record. Results Of 119 participants, 37 (31%) had inadequate health literacy. Patients with inadequate health literacy were less able to name any of their antihypertensive medications compared to those with adequate health literacy (40.5% vs 68.3%, p = 0.005). After adjusting for age and income, this difference remained (adjusted odds ratio [OR] = 2.9, 95% confidence interval [95%CI] = 1.3–6.7). Agreement between patient reported medications and the medical record was low: 64.9% of patients with inadequate and 37.8% with adequate literacy had no medications common to both lists. Conclusions Limited health literacy was associated with a greater number of unreconciled medications. Future studies should investigate how this may impact safety and hypertension control.

Comparison of Asthma-Related Functional Consequences and Health Care Utilization among Children with and without Upper Respiratory Infection-Triggered Wheezing

Objective. We compared differences in functional consequences and health care utilization in middle school-age children, based on whether they reported wheezing triggered by upper respiratory infections (URI-TW). Methods. Information on asthma symptoms, URI-TW, and functional consequence and health care use outcomes was collected from approximately 128,000 children; symptomatic participants were included in the analysis. Adjusted prevalence odds ratios were used to make comparisons. Results. URI-TW was significantly associated with most outcomes examined, with stronger associations at increasing levels of outcomes for sleep disturbances, school absences, activity limitations, physician visits, emergency room visits, hospitalizations, inhaler use, and tablets/pills to help breathing. Conclusion. Children who report URI-TW during their middle school years experience substantial morbidity and high health care utilization compared with symptomatic children without URI-TW.
