Learning your ABDs: Variation in health care utilization across Kansas Medicaid disability groups

BackgroundState Medicaid programs provide critical health care access for persons with disabilities and older adults. Aged, Blind and Disabled (ABD) programs consist of important disability subgroups that Medicaid programs are not able to readily distinguish.Objective/hypothesisThe purpose of this project was to create an algorithm based principally on eligibility and claims data to distinguish disability subgroups and characterize differences in demographic characteristics, disease burden, and health care expenditures.MethodsWe created an algorithm to distinguish Kansas Medicaid enrollees as adults with intellectual or developmental delays (IDD), physical disabilities (PD), severe mental illness (SMI), and older age.ResultsFor fiscal year 2009, our algorithm separated 101,464 ABD enrollees into the following disability subgroups: persons with IDD (19.6%), persons with PD (21.0%), older adults (19.7%), persons with SMI (32.8%), and persons not otherwise classified (6.9%). The disease burden present in the IDD, PD, and SMI subgroups was higher than for older adults. Home- and community-based services expenditures were common and highest for persons with IDD and PD. Older adults and persons with SMI had their highest expenditures for long-term care. Mean Medicaid expenditures were consistently higher for adults with IDD followed by adults with PD.ConclusionsThere are substantial differences between disability subgroups in the Kansas Medicaid ABD population with respect to demographics, disease burden, and health care expenditures. Through this algorithm, state Medicaid programs have the opportunity to collaborate with the most closely aligned service providers reflecting needed services for each disability subgroup.     

Tracking Oregon Medicaid patients' enrollment and health utilization patterns.

The Oregon Medicaid program consists of various sub-programs with different eligibility requirements and multiple health care delivery systems. Administrative events, such as the loss of Medicaid eligibility or a change in health plan enrollment, can cause disruptions in the continuity of medical care and may contribute to missed opportunities to provide appropriate medical services, including preventive care. Thus, in order to improve public health surveillance and describe the health care utilization patterns of Oregon's Medicaid beneficiaries, a standardized approach was developed to track the enrollment status of Medicaid patients for extended periods of time.     

Medicaid behavioral health care plan satisfaction and children's service utilization

This study examines associations between caregivers' satisfaction with children's Medicaid-funded behavioral health care plans and the likelihood that children with severe emotional disturbance receive mental health services. Data are from a multisite study of managed care versus fee-for-service (FFS) settings. In multivariate logistic regression analyses controlling for demographic, environmental, site, and clinical characteristics, plan satisfaction was associated with greater likelihood of subsequent service use regardless of managed care versus FFS setting. Children in managed care plans were less likely to use intensive residential and non-traditional outpatient services. Efforts to increase plan satisfaction may encourage service use, consequently, improving children's behavioral health outcomes.     

Integrated care models and behavioral health care utilization: Quasi‐experimental evidence from Medicaid health homes

Integration of behavioral and general medical care can improve outcomes for individuals with behavioral health conditions—serious mental illness (SMI) and substance use disorder (SUD). However, behavioral health care has historically been segregated from general medical care in many countries. We provide the first population‐level evidence on the effects of Medicaid health homes (HH) on behavioral health care service use. Medicaid, a public insurance program in the United States, HHs were created under the 2010 Affordable Care Act to coordinate behavioral and general medical care for enrollees with behavioral health conditions. As of 2016, 16 states had adopted an HH for enrollees with SMI and/or SUD. We use data from the National Survey on Drug Use and Health over the period 2010 to 2016 coupled with a two‐way fixed‐effects model to estimate HH effects on behavioral health care utilization. We find that HH adoption increases service use among enrollees, although mental health care treatment findings are sensitive to specification. Further, enrollee self‐reported health improves post‐HH.

The Nebraska Medicaid managed behavioral health care initiative: Impacts on utilization,expenditures, and quality of care for mental health

This study evaluates the impact of Nebraska's Medicaid managed care program for behavioral health services on mental health service utilization, expenditures, and quality of care. Implementation of the program is correlated with progressive reductions in both total (about 13% over 3 years) and per eligible per month (20%) expenditures and a rapid, extensive decline in inpatient utilization and admissions. The percentage of enrollees receiving any type of treatment for a mental disorder actually increased modestly. Most important, several indicators of quality of care (eg, timely receipt of ambulatory care following discharge from inpatient care and readmission to inpatient care shortly following discharge) suggest that quality of care did not materially change under the carve-out. Although a thorough assessment of quality of care impacts is warranted, this study suggests implementation of a managed care program may allow states to reduce Medicaid expenditures without compromising quality of care.     

Factors influencing antenatal care service utilization in hadiya zone

Background

In Ethiopia, the levels of maternal and infant morbidity and mortality are among the highest in the world. This is attributed to, among other factors, none use of modern health care services by women in Ethiopia. According to the 2005 Ethiopian Demographic Health Survey, more than seven in ten mothers did not receive antenatal care at all. Therefore, the objective of this study was to explore factors influencing antenatal care services utilization in Southern Ethiopia.

Methods

A community-based cross sectional study was conducted in Hadiya Zone of Southern Ethiopia from January to February 2009. A multi stage sampling technique was used to select the study population in one urban and five rural kebeles. Analysis was done using SPSS for windows version 16.

Result

This study revealed that antenatal care service utilization in the study area was 86.3%. However, from those who attended antenatal care service 406 (68.2%) started antenatal care visit during the second trimester of pregnancy and significant proportion 250 (42%) had less than four visits. Maternal age, husband attitude, family size, maternal education, and perceived morbidity were major predictors of antenatal care service utilization.

Conclusion

Though the antenatal care service utilization is high in the study population, four in ten of the mothers did not have the minimum number of visits recommended by World Health Organization. Promoting information, education and communication in the community is recommended to favorably affect the major predictors of antenatal care service utilization.     

The effect of health insurance coverage on medical care utilization and health outcomes: Evidence from Medicaid adult vision benefits

Increasing the proportion of adults that have regular, comprehensive eye exams and reducing visual impairment due to uncorrected refractive error and other common eye health problems are federal health objectives. We examine the effect of vision insurance on eye care utilization and vision health outcomes by taking advantage of quasi-experimental variation in Medicaid coverage of adult vision care. Using a difference-in-difference-in-difference approach, we find that Medicaid beneficiaries with vision coverage are 4.4 percentage points (p < 0.01) more likely to have seen an eye doctor in the past year, 5.3 percentage points (p < 0.01) less likely to report needing but not purchasing eyeglasses or contacts due to cost, 2.0 percentage points (p < 0.05) less likely to report difficulty seeing with usual vision correction, and 1.2 percentage points (p < 0.01) less likely to have a functional limitation due to vision.     

Factors influencing professional home care utilization among the elderly

Most explanatory research into the utilization of home care for the elderly has been carried out in a cross-sectional design with multiple regression as the main method of analysis. For methodological reasons we chose another design in a project called 'Professional home care and informal help for the elderly', which has been conducted in the northern part of the Netherlands. Two types of causal variables were distinguished to detect influencing factors on professional home care utilization among the elderly, other than physical limitation: person-bound variables and social network variables. A Mokken Scale analysis for Polychotomous items (MSP) was used to measure the level of physical limitation and a matching procedure to compare 'users' and 'non-users' of professional home care. With regard to person-bound variables, sex, whether or not a person was living alone and the level of the elderly person's income appeared to play a role in the utilization of home care: the user group comprised significantly more women, more elderly living alone and more persons on a low income. Contrary to the findings in other Dutch research, depression and feelings of loneliness did not seem to discriminate between the two groups. With regard to social network variables, the size and structure of the social network was more or less identical in both groups. The non-users network lives slightly closer. In general, the small differences found between the groups were to the non-users' advantage. Moreover, the non-users received more informal and private care with ADL and IADL activities.

Medicaid managed care in Chicago: changes in utilization

In 1993, Illinois implemented Healthy Moms/Healthy Kids (HM/HK) in Chicago, a Medicaid managed care program for pregnant women and children. This study examines changes in immunizations for children (n = 134,072), prenatal care use for pregnant women (n = 5,151), and inpatient stays for mothers (n = 5,151) and newborns (n = 2,699) under the HM/HK program as compared with fee-for-service Medicaid in 1992 and 1993. HM/HK children were 10 percent more likely to receive any immunizations, and HM/HK pregnant women were 13 percent more likely to receive some prenatal care. Mothers' inpatient stays at delivery did not change under HM/HK. The length of newborn stays fell between 1992 and 1993, with both the HM/HK and the Medicaid 1993 comparison group deliveries associated with statistically shorter stays. During the early months of the program, improvements in the quantity of expected preventive care received were evident among children and women.     

Medicaid managed care and infant health

This paper provides estimates of the effects of Medicaid managed care on prenatal care adequacy and infant birthweights, using a census of 1994 Medicaid births in Wisconsin, where some Medicaid recipients were enrolled in fully capitated health maintenance organizations (HMOs) while others remained in traditional fee-for-service (FFS) systems. The results indicate that while Medicaid patients enrolled in managed care programs may be more likely to receive adequate prenatal care, birth outcomes under managed care are not significantly different from those under FFS financing systems. We conclude that cost savings generated by Wisconsin Medicaid managed care are not coming at the expense of maternity patients' or infants' welfare.     

Unmet health care and health care utilization

The objective of this study is to examine the causal effect of health care utilization on unmet health care needs. An IV approach deals with the endogeneity between the use of health care services and unmet health care, using the presence of drug insurance and the number of physicians by health region as instruments. We employ three cycles of the Canadian Community Health Survey confidential master files (2003, 2005, and 2014). We find a robustly negative relationship between health care use and unmet health care needs. One more visit to a medical doctor on average decreases the probability of reporting unmet health care needs by 0.014 points. The effect is negative for the women‐only group whereas it is statistically insignificant for men; similarly, the effect is negative for urban dwellers but insignificant for rural ones. Health care use reduces the likelihood of reporting unmet health care. Policies that encourage the use of health care services, like increasing the coverage of public drug insurance and increasing after hours accessibility of physicians, can help reduce the likelihood of unmet health care.     

The health care experiences of rural Medicaid beneficiaries

Medicaid plays a vital role in rural America, yet, because of data limitations, little research exists on the health care experiences of low-income rural adults. We use data from the National Survey of America's Families, with its oversample of low-income populations, to examine differences in access to and use of care between urban and rural Medicaid beneficiaries, and between Medicaid beneficiaries and low-income privately insured adults in urban and rural areas. We find evidence that access to care under Medicaid is worse than under private insurance in both urban and rural areas; however, Medicaid beneficiaries have a more consistent level of access across urban and rural areas than do low-income privately insured people.     

Factors associated with Medicaid enrollment for low-income children in the United States

This study analyzes the 1996-1997 Community Tracking Study Household Survey to identify factors associated with Medicaid enrollment for low-income children and to examine the differences between those enrolled in the Medicaid program and those who were eligible but uninsured. We estimated that 17.4% of Medicaid-eligible children were uninsured. Medicaid eligible children who were younger, African American, with single parents, with AFDC eligible parents, with no parent employed full-time were more likely to be enrolled in the Medicaid program. Children with better health status were less likely to be enrolled in Medicaid. In addition, children whose parents were uninsured were more likely not to be enrolled in Medicaid.     

Factors influencing early prenatal enrollment in the WIC program

Women's access to prenatal nutrition services was explored using a nationally representative sample of pregnant participants in the Special Supplemental Food Program for Women, Infants, and Children (WIC) in 1984. The probability was examined of the participant entering the program during her first trimester, rather than the second or third trimester. Other research has suggested that length of participation in the program during pregnancy is associated with increased birth weight. The data were adjusted for various personal and local operational factors, such as prior WIC participation, race, age, income, household size, WIC priority level, availability of prenatal or other health services, targeted outreach policies, years of local operation, and local agency size. Previous participation in the WIC Program was the only factor significantly associated with early enrollment (adjusted odds ratio 2.1). Race was marginally significant. Neither the presence of local policies of outreach targeted to pregnant women, nor co-location of WIC services with prenatal or other health services, showed significant effects on early enrollment.     

The relationship of post-acute home care use to Medicaid utilization and expenditures

RESEARCH OBJECTIVES: To describe the use of post-acute home care (PAHC) and total Medicaid expenditures among hospitalized nonelderly adult Medicaid eligibles and to test whether health services utilization rates or total Medicaid expenditures were lower among Medicaid eligibles who used PAHC compared to those who did not. STUDY POPULATION: 5,299 Medicaid patients aged 18-64 discharged in 1992-1996 from 29 hospitals in the Cleveland Health Quality Choice (CHQC) project. DATA SOURCES: Linked Ohio Medicaid claims and CHQC medical record abstract data. DATA EXTRACTION: One stay per patient was randomly selected. DESIGN: Observational study. To control for treatment selection bias, we developed a model predicting the probability (propensity) a patient would be referred to PAHC, as a proxy for the patient's need for PAHC. We matched 430 patients who used Medicaid-covered PAHC ("USE") to patients who did not ("NO USE") by their propensity scores. Study outcomes were inpatient re-admission rates and days of stay (DOS), nursing home admission rates and DOS, and mean total Medicaid expenditures 90 and 180 days after discharge. PRINCIPAL FINDINGS: Of 3,788 medical patients, 12.1 percent were referred to PAHC; 64 percent of those referred used PAHC. Of 1,511 surgical patients, 10.9 percent were referred; 99 percent of those referred used PAHC. In 430 pairs of patients matched by propensity score, mean total Medicaid expenditures within 90 days after discharge were $7,649 in the USE group and $5,761 in the NO USE group. Total Medicaid expenditures were significantly higher in the USE group compared to the NO USE group for medical patients after 180 days (p < .05) and surgical patients after 90 and 180 days (p < .001). There were no significant differences for any other outcome. Sensitivity analysis indicates the results may be influenced by unmeasured variables, most likely functional status and/or care-giver support. CONCLUSIONS: Thirty-six percent of the medical patients referred to PAHC did not receive Medicaid-covered services. This suggests potential underuse among medical patients. The high post-discharge expenditures suggest opportunities for reducing costs through coordinating utilization or diverting it to lower-cost settings. Controlling for patients' need for services, PAHC utilization was not associated with lower utilization rates or lower total Medicaid expenditures. Medicaid programs are advised to proceed cautiously before expanding PAHC utilization and to monitor its use carefully. Further study, incorporating non-economic outcomes and additional factors influencing PAHC use, is warranted.
