Outcomes for Medicaid beneficiaries with schizophrenia under a prepaid mental health carve-out.

This study examines the impact of a mental health carve-out program in Utah on mental health status of Medicaid beneficiaries with schizophrenia. Three community mental health centers contracted to provide mental health care for all Medicaid beneficiaries in their service areas under managed care arrangements, while beneficiaries in the remainder of the state remained under traditional Medicaid. A pre-post evaluation was utilized, with a contemporaneous control group of Utah Medicaid beneficiaries with schizophrenia under traditional Medicaid. From 1991 to 1994, the average beneficiary's mental health status improved, but the improvement was less under the carve-out program than under traditional fee-for-service Medicaid. The difference was the greatest for beneficiaries with the worst mental health status at baseline, with effects growing over time. Medicaid beneficiaries with schizophrenia experienced less improvement in mental health status under a carve-out arrangement for mental health care compared to what would have happened under traditional Medicaid.

Patterns of outpatient use of mental health services for Medicaid beneficiaries under a prepaid mental health carve-out.

This study examines the impact of a mental health carve-out, the Utah Prepaid Mental Health Plan (UPMHP), on use of outpatient mental health services by Medicaid beneficiaries with schizophrenia. Data were collected through interviews with the same group of Medicaid schizophrenic beneficiaries. A pre/post comparison with a contemporaneous control group examined the impact of the program on type of outpatient services used by beneficiaries. The results indicate a greater reliance on medically-oriented outpatient mental health services in treatment of beneficiaries under the UPMHP. Medicaid beneficiaries with schizophrenia in the UPMHP group received relatively fewer day treatment visits, but relatively more medication visits and individual therapy visits over the first 3 1/2 years of the program.

The prevalence and effects of hunger in an emergency department patient population.

OBJECTIVES: Little is known about the prevalence and health effects of hunger among ED patients. The objectives of this study were to determine the prevalence of hunger among patients in a large urban ED and to examine whether it has adverse health effects. METHODS: A survey about hunger, choices between buying food and buying medicine, and adverse health outcomes related to food adequacy over the preceding 12 months was administered to a convenience sample of adult non-critically ill ED patients from afternoon and evening shifts. The study was conducted in the ED of Hennepin County Medical Center in Minneapolis, Minnesota. RESULTS: Of the 302 eligible patients who were asked to participate, 297 (98%) agreed. Eighteen percent reported not having enough to eat at least once in the preceding 12 months: 14% reported that they had "gotten sick" as a result of not being able to afford their medicine, resulting in an ED visit or hospital admission 50% of the time. Predictors of making choices about buying food vs medicine include having a chronic health condition, lack of private health insurance, having a reduction in food stamps, having an annual income less than $10,000, and lack of alcohol use. By patient report, a reduction in food stamps was a predictor of ED visits and hospitalizations as a result of making choices about buying food over medicine. CONCLUSION: The ED patients in this urban setting have high rates of hunger and many must make choices between buying food and medicine, which patients report results in otherwise preventable ED visits and hospitalization. Loss or reduction of food stamps is associated with increased hunger and increased perceived adverse health outcomes as a result of not being able to afford medicine.

Screening for asthma in an inner-city elementary school in Minneapolis, Minnesota.

To the extent that the asthma morbidity so prevalent in children today is due to underdiagnosis or lack of appropriate treatment, schools are increasingly faced with the issue of defining their role in the care of children with asthma. This paper describes efforts to conduct schoolwide screening for asthma in an inner-city elementary school over the past two years. Screening methodology adopted for the project resulted in a simple and noninvasive approach for identifying children with current asthma in a school setting. While not as medically comprehensive as would be required to conclusively diagnose asthma, the simple screening approach proved efficient in identifying a population of elementary school children with a significant level of asthma morbidity. The paper discusses the effectiveness and feasibility of the screening efforts and proposes how such a screening program might be incorporated into the routine health activities undertaken at any elementary school.

Hunger in an adult patient population.

CONTEXT: Although clinical observations suggest that some patients experience hunger and food insecurity, there are limited data on the prevalence of hunger in adult patients. OBJECTIVE: To determine the prevalence of hunger and food insecurity in adult patients at an urban county hospital. DESIGN: Cross-sectional survey conducted in 1997. PATIENTS: The primary survey included all patients aged 18 years or older who were admitted to the medicine, surgery, and neurology services during a 2-week period, and all patients who attended the hospital's general medicine clinic during 1 week. A second survey included primary care patients who received insulin from the hospital pharmacy during a 1-month period. MAIN OUTCOME MEASURES: Rates of hunger and food insecurity. RESULTS: Of 709 eligible patients, 567 (participation rate, 80%) were interviewed in either the clinic (n=281) or hospital (n=286). An additional 170 patients who received insulin were interviewed by telephone (response rate, 75%). Of the primary sample, 68 (12%) respondents reported not having enough food, 75 (13%) reported not eating for an entire day, and 77 (14%) reported going hungry but not eating because they could not afford food. A total of 222 (40%) had received food stamps in the previous year and of those, 113 (50%) had their food stamps reduced or eliminated. Recipients whose food stamps had been eliminated or reduced were more likely to report not having enough food (18% vs 13%, P=.006), not eating for a whole day (20% vs 16%, P=.01), going hungry but not eating (20% vs 16%, P=.08), and cutting down on the size of meals or skipping meals (33% vs 27%, P=.01). In multivariate analysis, independent predictors of hunger included an annual income of less than $10000 (odds ratio [OR], 7.55; 95% CI, 3.01-18.92), drug use (OR, 3.56; 95% CI, 1.46-8.66), and a reduction in food stamp benefits (OR, 1.73; 95% CI, 1.01-2.96). Predictors of food insecurity included an annual income of less than $10000 (OR, 4.12; 95% confidence interval [CI], 1.98-8.58), drug use (OR, 2.11; 95% CI, 1.66-5.08), and a reduction in food stamps (OR, 2.02; 95% CI, 1.23-3.32). In addition, 103 (61%) patients in the sample of diabetics reported hypoglycemic reactions; 32 (31%) of these were attributed to inability to afford food. CONCLUSION: Hunger and food insecurity are common among patients seeking care at an urban county hospital.

Accuracy of self-report of mammography and Pap smear in a low-income urban population.

BACKGROUND: Cancer screening history can often be obtained only by self-report, particularly for disadvantaged populations. We examined the accuracy of self-report of mammography and Pap smear for an urban, low-income population. METHODS: Women attending non-primary care clinics (mostly surgery and orthopedics) at a large public teaching hospital in Minneapolis between July 1992 and May 1993 were queried about their screening history (n = 477). The women were interviewed by a trained peer-recruiter and asked whether they had ever heard of a Pap smear or mammogram, whether they had ever had one, where it was done, and when the last one was. We verified self-report by checking medical records where the test was performed. RESULTS: The positive and negative predictive value of recall of mammography in the previous year was 72.4% and 90.6%, respectively. The figures for Pap smear recall were somewhat lower, 65.5% and 85.9%, respectively. We found a record of a mammogram in 88% of women able to recall the year. Of these, slightly over two-thirds recalled their mammogram in the same year as their record indicated. Inaccurate recalls were more commonly of the "telescoping" type, i.e., tests were recalled as having occurred more recently than was the case. Recall was substantially better for recent tests. Results for Pap smear recalls were broadly similar. CONCLUSIONS: The accuracy of self-report of mammography and Pap smear is relatively poor for medical practice but is acceptable in population surveys with appropriate correction for overreporting.

Increasing breast and cervical cancer screening in low-income women.

OBJECTIVE: To determine if women would have higher breast and cervical cancer screening rates if lay health advisers recommended screening and offered a convenient screening opportunity. DESIGN: Controlled trial. SETTING: Urban county teaching hospital. PARTICIPANTS: Women aged 40 years and over attending appointments in several non-primary-care outpatient clinics. INTERVENTIONS: Lay health advisers assessed the participants' breast and cervical cancer screening status and offered women in the intervention group who were due for screening an appointment with a female nurse practitioner. MEASUREMENTS AND MAIN RESULTS: Screening rates at baseline and at follow-up 1 year after the intervention were determined. At follow-up, the mammography rate was 69% in the intervention group versus 63% in the usual care group (p = .009), and the Pap smear rate was 70% in the intervention group versus 63% in the usual care group (p = .02). In women who were due for screening at baseline, the mammography rate was 60% in the intervention group versus 50% in the usual care group (p = .006), and the Pap smear rate was 63% in the intervention group versus 50% in the usual care group (p = .002). The intervention was effective across age and insurance payer strata, and was particularly effective in Native American women. CONCLUSIONS: Breast and cervical cancer screening rates were improved in women attending non-primary-care outpatient clinics by using lay health advisers and a nurse practitioner to perform screening. The effect was strongest in women in greatest need of screening.

Women's preferences for specialists who provide cancer screening and general medical care.

In order to determine what types of specialists women prefer for medical care, we examined responses from a cross-sectional survey of adult female patients in a health plan of the independent practice association model in the Minneapolis-St. Paul metropolitan area (n = 1,204). The response rate for the survey was 90%. The women expressing a preference (60% of responders) overwhelmingly preferred to see obstetrician-gynecologists for their breast examinations and Pap smears and strongly preferred family physicians or internists for the remainder of their cancer screening and general medical care. Thus, the majority of women expressed preferences for physicians of different specialties to provide their medical care.

Changes in the process of care for Medicaid patients with schizophrenia in Utah's Prepaid Mental Health Plan.

OBJECTIVE: Changes in the process of psychiatric care received by Medicaid beneficiaries with schizophrenia were examined after the introduction of capitated payments for enrollees of some community mental health centers (CMHCs) under the Utah Prepaid Mental Health Plan. METHODS: Data from the medical records of 200 patients receiving care in CMHCs participating in the prepaid plan were compared with data from the records of 200 patients in nonparticipating CMHCs, which remained in a fee-for-service reimbursement arrangement. Using the Process of Care Review Form, trained abstracters gathered data characterizing general patient management, social support, medication management, and medical management before implementation of the plan in 1990 and for three follow-up years. Using regression techniques, differences in the adjusted changes between third-year follow-up and baseline were examined by treatment site. RESULTS: By year 3 at the CMHCs participating in the plan, psychotherapy visits decreased, the probability of a patient's terminating treatment or being lost to follow-up increased, the probability of having a case manager increased, the probability of a crisis visit decreased (but still exceeded that at the nonplan sites), and the probability of treatment for a month or longer with a suboptimal dosage of antipsychotic medication increased. Only modest changes in the process of care were observed at the nonplan CMHCs. CONCLUSIONS: Change in the process of psychiatric care was more evident at the sites participating in the plan, where traditional therapeutic encounters were de-emphasized in response to capitation. The array of changes raises questions about the vigor of care provided to a highly vulnerable group of patients.

Monitoring the consequences of uninsurance: a review of methodologies.

The proportion of the United States population without health insurance continues to grow. How will this affect the health of the nation? Prior research suggests that the uninsured are at risk for poor health outcomes. They use fewer medical services and have higher mortality rates than do insured persons. The episodic nature of uninsurance and its prevalence among disadvantaged groups makes it difficult to ascertain the health effects of uninsurance. The goal of this review is to assist researchers and policy makers in choosing methodologies to assess the effects of uninsurance. It provides a compendium of methods that have been used to examine the health consequences of uninsurance, the populations in which these methods have been used, and the strengths and weaknesses of different approaches. The review highlights the need for more longitudinal studies that focus on community-based samples of the uninsured.

Who is still uninsured in Minnesota? Lessons from state reform efforts.

OBJECTIVE: To describe Minnesota's health care system reform efforts and their implications for other state and national reform initiatives, document the rate of uninsurance in 1990 and 1995 with special attention to childrens' access to health insurance, and examine the effectiveness of MinnesotaCare, a voluntary state-subsidized health care plan, in serving its target population. DESIGN: Three cross-sectional telephone surveys: 2-stage random samples of Minnesotans of all ages in 1990 and 1995 and a stratified random sample of MinnesotaCare enrollees in 1994. PARTICIPANTS: For the 2 statewide surveys, 10310 respondents participated in 1990 and 11519 in 1995; more detailed information was collected on approximately 1600 respondents in each survey. Eight hundred MinnesotaCare enrollees participated in the third survey conducted in 1994. MAIN OUTCOME MEASURE: Changes in rates of uninsurance. RESULTS: While the rate of uninsurance increased at the national level, the point-in-time Minnesota rate remained stable and low at 6% between 1990 and 1995. The proportion of children uninsured for 12 months or more decreased from 5.2% in 1990 to 3.1% in 1995, while the proportion of uninsured single adults remained stable at approximately 11%. There was no evidence that MinnesotaCare enrollees are gaming the program, or that the program has resulted in significant erosion from the private market. CONCLUSIONS: MinnesotaCare has enabled the state to maintain a low rate of uninsurance and has reduced this rate among its primary target: children. The program has been less effective in enrolling single adults, although it may be too early to witness the effects of recent expansions targeting this group. Minnesota's experience suggests that other state and national reform efforts aimed at reducing uninsurance, particularly among children, are likely to be successful.

Are all health plans created equal? The physician's view.

CONTEXT: The health care market is demanding increasing amounts of information regarding quality of care in health plans. Physicians are a potentially important but infrequently used source of such information. OBJECTIVE: To assess physicians' views on health plan practices that promote or impede delivery of high-quality care in health plans and to compare ratings between plans. SETTING: Minneapolis-St Paul, Minn. PARTICIPANTS: One hundred physicians in each of 3 health plans. Each physician rated 1 health plan. MAIN OUTCOME MEASURES: Likert-type items that assessed health plan practices that promote or impede delivery of high-quality care. RESULTS: A total of 249 physicians (84%) completed the survey. Fewer than 20% of all physicians gave plans the highest rating (excellent or strongly agree) for health plan practices that promote delivery of high-quality care (such as providing continuing medical education for physicians, identifying patients needing preventive care, and providing physicians feedback about practice patterns). Barriers to delivering high-quality care related to sufficiency of time to spend with patients, covered benefits and copayment structure, and utilization management practices. Ratings differed across health plans. For example, the percentage of physicians indicating that they would recommend the plan they rated to their own family was 64% for plan 1, 92% for plan 2, and 24% for plan 3 (P<.001 for all comparisons). CONCLUSIONS: Physician surveys can highlight strengths and weaknesses in health plans, and their ratings differ across plans. Physician ratings of health plan practices that promote or impede delivery of high-quality care may be useful to consumers and purchasers of health care as a tool to evaluate health plans and promote quality improvement.

Why do patients of female physicians have higher rates of breast and cervical cancer screening?

OBJECTIVE: Women are more likely to receive breast and cervical cancer screening if they see female physicians. We studied whether this is due to differences between male and female physicians, or to differences in their patients. SETTING: Large midwestern, independent practice association style of health plan. DESIGN: We surveyed male and female primary care physicians matched for age and specialty and a stratified random sample of three of each physician's women patients. Physicians reported on their practice setting, their attitudes and practices regarding prevention, and their comfort and skill with various examinations. Patients reported on their sociodemographic characteristics, their attitudes and practices regarding prevention, and their preferences for physician gender. Claims data were used to calculate mammography and Pap smear screening rates for the physicians. PARTICIPANTS: We studied 154 female and 190 male internists and family physicians and 794 of their patients. MEASUREMENTS AND MAIN RESULTS: We compared the responses of male and female physicians and their patients and used multivariable analysis to identify the patient and physician factors that accounted for the differences in screening rates between male and female physicians. Female physicians were more likely to ask new patients about components of prevention, to believe in the effectiveness of mammography, to feel more personal responsibility for ensuring that their patients received screening, and to report more comfort in performing Pap smears and breast examinations. Patients of female physicians were more educated and less likely to be married, but did not differ in other sociodemographic characteristics. They had similar attitudes and practices regarding prevention, except that patients of male physicians were more likely to smoke. Significantly more patients of female physicians preferred a female for some component of care. In multivariable analyses, practice organization, patient preference for a female physician, and prevention orientation of female physicians accounted for up to 40% of screening rate differences between female and male physicians for Pap smears, and 33% for mammography. CONCLUSIONS: Differences in beliefs of male and female physicians and patient preference for a female provider contribute independently to the higher rate of breast and cervical cancer screening by female physicians.

Development and testing of a process measure of nursing home quality of care.

OBJECTIVE: To develop and test quality of care process measures for three medical conditions of nursing home patients: fever, shortness of breath, and chest pain. DESIGN: Flowsheets designed to capture the critical elements of care for the above conditions were developed by an expert panel. Nursing home residents charts were reviewed retrospectively using the flow sheets. The reviews were translated into clinical scenarios, and the quality of care the scenarios represented was rated by an expert panel. SETTING: All nursing homes in Hennepin County, MN, that care for Medicaid patients. PATIENTS: A random sample of 1405 Medicaid nursing home residents from 1984 and 1988. MEASURES: Measures of quality of physician assessment and intervention, quality of nurse assessment and intervention, and global quality were developed and the intra- and interrater reliability were tested. The measures' validity was assessed by their ability to predict resident death. RESULTS: Intrarater reliability was measured as the correlation of the ratings of blinded duplicates. The correlation for the global scale and the four subscales ranged from .74 to .88 (P < .001 for all). Interrater reliability was tested by examining what percentage of the quality ratings were within one unit (1-5 scale) for all three raters. All three raters were within one unit for more than 72% scenarios for all scales. The subscale of quality of physician assessment was able to predict resident death when the worst episode of care (OR = .47, 95% CI(.31-.74)) or the mean episode of care (OR .54, 95% CI(.30-.99)) was used. None of the other subscales or the global measure predicted death. CONCLUSIONS: Through the use of an expert panel, measures of nursing home quality of care were developed for shortness of breath, fever, and chest pain. These measures have reasonable reliability and significant face validity. Their validity is supported further by the ability of one of the measures to predict resident death.

An instrument to evaluate the process of psychiatric care in ambulatory settings.

As part of an evaluation of the Utah Prepaid Mental Health Plan, the Process of Care Review Form was developed to assess the quality of the process of psychiatric care provided by Utah's community mental health centers (CMHCs) to clients with schizophrenia. This article briefly reviews issues in the measurement of quality of care and describes the development and implementation of the form. The 67-item form was designed for use by a trained abstracter to gather data from CMHC medical records in six areas: general management of the patient, medication management, medical management, social support, psychiatric hospitalization, and psychiatric assessment. A 59-item version of the form that omits the section on psychiatric assessment has been used in three waves of data collection to document data spanning five years (1990-1994) in the evaluation of the process of psychiatric care in the Utah plan. It is currently being used longitudinally to examine differences between Utah CMHCs receiving capitated payments and those paid on a fee-for-service basis by Medicaid.
