Effect of high up front charges on access to surgery for poor patients at a public hospital in New Mexico.

BACKGROUND: A public hospital in New Mexico required collection of 50% of estimated costs prior to elective surgeries for self-pay patients. This study assesses the impact of this policy on access to elective surgical procedures. METHODS: Chi-square tests determined if there was a statistically significant difference between the number of self-pay and insured patient cancellations for financial reasons. A multivariate binomial regression model was used to calculate risk ratios and confidence limits for effects of race/ethnicity, and insurance status, controlling for gender, on these cancellations. RESULTS: Of the 667 cancellations, there were 99 self-pay and 568 insured patients. Cancellations for financial reasons occurred in 55.6% of self-pay and 9.3% of insured patients (p < 0.0001). Inability to pay 50% up front accounted for 76.4% of self-pay patient cancellations for financial reasons. Self-pay, non-Hispanic whites and minority race/ethnicities were 8.76 and 8.61 times more likely to cancel for financial reasons, respectively, than insured non-Hispanic whites. CONCLUSION: Self-pay patients, regardless of race/ethnicity, have elective surgical procedures cancelled for financial reasons significantly more often than insured patients. The hospital's 50% up-front payment policy represents a significant financial barrier to accessing elective surgical procedures for self-pay patients.

Web-based primary care referral program associated with reduced emergency department utilization.

BACKGROUND AND OBJECTIVES: Uninsured patients without a primary care home tend to use the emergency department (ED) for primary care. We examined whether an enhanced scheduling system for follow-up care from the University of New Mexico Hospital Emergency Department (UNMH-ED) that assigns patients to a family medicine home can decrease ED utilization. METHODS: The Community Access Program for Central New Mexico (CAP-NM) is a consortium of primary care safety net provider organizations. CAP-NM developed a HIPAA-compliant (Health Insurance Portability and Accountability Act), Web-based information system used by the UNMH-ED to refer uninsured, unassigned patients to family medicine practices ("homes") within the consortium. The Web site referral system operated 24 hours a day, 7 days a week; printed maps to clinic sites; and listed services offered. Analysis of quality assurance data compared (1) ED utilization outcomes of eligible patients referred by the CAP-NM Web site to a family medicine home to (2) outcomes of controls discharged from the ED in the usual manner. RESULTS: The 756 patients referred to family medicine homes through the CAP-NM Web site demonstrated a significant 31% reduction in subsequent ED visits compared to controls. This reduction was most evident among those who had infrequent ED use before institution of the program. CONCLUSIONS: Implementing an enhanced referral system to family medicine homes from the ED is associated with decreased subsequent ED utilization by uninsured patients.

Emotional responses to APO E genotype disclosure for Alzheimer disease.

The purpose of our study is to assess the emotional responses to disclosing APO E genotype to asymptomatic older adults at increased risk for Alzheimer disease (AD). This is a longitudinal cohort study of volunteer subjects who were aged 50 years or over, asymptomatic for (AD), had a family history of AD, passed a psychological assessment, and participated in pre- and post-test genetic counseling and three follow-up visits over 10 months. We analyzed responses by three emotional constructs: depressed, worried, and relieved. Three hundred and twenty-eight subjects were screened, 76 received their APO E genotype. When emotional responses occurred it was immediate, between baseline and the 1 month follow-up. Emotional reactions did not change significantly past 1 month. Our results suggest that for emotionally stable persons, disclosing results of their APO E genotype, high risk subjects did not report more depression or worry and low risk subjects felt relieved by knowing the results. Future studies should evaluate the risks of disclosure to family members involved in the diagnostic work-up of a relative and include subjects from a broader range of emotional stability and socioeconomic background.

Renin-angiotensin polymorphisms and QTc interval prolongation in end-stage renal disease.

BACKGROUND: Polymorphisms of renin-angiotensin system (RAS) genes in patients with end-stage renal disease (ESRD) on chronic hemodialysis may be associated with QTc interval prolongation, leading to fatal arrhythmias. The objective of this study was to determine (1) the prevalence of QTc prolongation in hemodialysis patients, and (2) the association of a prolonged QTc in these patients with RAS polymorphisms [angiotensin-converting enzyme-insertion/deletion (ACE-I/D), angiotensin type 1 receptor-A1166C (AT1R-A1166C), and angiotensinogen-M235T (AGT-M235T)]. METHODS: Twelve-lead electrocardiograms (ECGs), serum electrolytes (sodium, potassium, and calcium), and ACE and angiotensin II levels were obtained 10 to 12 hours after a hemodialysis session in 43 patients with ESRD on chronic hemodialysis [mean age (+/-SD), 55 +/- 14 years]. Using polymerase chain reaction (PCR), the presence of polymorphisms of the ACE-I/D, AT1R-A1166C, and AGT-M235T genes was determined from the buccal cells. A maximum QT interval in patients with sinus rhythm and normal QRS duration was corrected for heart rate using Hodges' formula. RESULTS: Fifty-eight percent of the patients had QTc interval prolongation (>440 msec). The ACE-DD genotype (P = 0.002) and the C allele of the AT1R-A1166C gene (P = 0.004), but not the AGT-M235T gene, contributed to QTc prolongation. CONCLUSION: Polymorphisms of ACE and AT1R genes additively contribute to QTc prolongation found in a great majority of ESRD patients. Therefore, ESRD patients with both or one of these polymorphisms may be at a higher risk for sudden cardiac death.

Effect of managed care on emergency department use in an uninsured population.

STUDY OBJECTIVE: The use of managed care to decrease emergency department (ED) use has been reported with some success among Medicaid and insured populations. Our objective is to determine the effect of a managed care program (the "Program") for uninsured patients on their use of emergency, inpatient, and outpatient services. METHODS: This was a retrospective, observational study with 3 groups of patients at an urban, academic medical center: uninsured patients enrolled in the Program, uninsured patients not enrolled in the Program ("Uninsured"), and commercially insured ("Commercial") patients. All patients received services at least once annually during the 5-year study duration. Administrative databases provided data on ED visits, hospital discharges, hospital days, primary care visits, and specialty care visits during the preprogram and 4 postprogram years. RESULTS: There were 1,676 Program, 335 Uninsured, and 844 Commercial patients (2,855 total patients). Use of emergency, inpatient, and outpatient specialty clinics by all groups did not change significantly after program implementation. There was a modest increase in outpatient primary care use by Program members. CONCLUSION: Implementation of a managed care program did not significantly alter ED or inpatient hospital use patterns in an uninsured, indigent population. Providing a primary care provider and health care benefits alone was insufficient to reduce ED use in this population.

Child maltreatment prevalence and mental disorders outcomes among American Indian women in primary care.

OBJECTIVE: To examine (1) the prevalence, types, and severity of child abuse and neglect (CAN) and (2) the relationship between CAN and lifetime psychiatric disorders among American Indian women using primary care services. METHODS: A cross-sectional study was conducted among 234 American Indian women, age 18-45 who presented for outpatient ambulatory services at a community-based Indian Health Service Hospital in Albuquerque, New Mexico. Dependent measures included mood, substance abuse, and anxiety disorders as well as posttraumatic stress disorder (PTSD) as measured by the Composite International Diagnostic Interview. CAN was assessed using the Childhood Trauma Questionnaire. RESULTS: Approximately three-quarters of respondents (76.5%; 95% CI = 70.4, 81.7) reported some type of childhood abuse or neglect; over 40% reported exposure to severe maltreatment. Severity of child maltreatment was associated in a dose response manner with lifetime diagnosis of mental disorders. After adjusting for social and demographic correlates, severe child maltreatment was strongly associated with lifetime PTSD (prevalence ratio [PR] 3.9; 95% CI = 1.9, 8.0); and was moderately associated with lifetime substance use disorders (PR = 2.3; 95% CI = 1.6, 3.3); mood disorders (PR = 2.1; 95% CI 1.4, 3.2); and with two or more disorders (PR = 2.3; 95% CI = 1.6, 3.4). CONCLUSION: CAN was common in our sample of American Indian women in primary care and was positively associated with lifetime psychiatric disorders outcomes. Screening for CAN and psychiatric disorders would enhance the treatment of patients seeking primary care services. Primary prevention of child maltreatment might reduce the high prevalence of mental disorders among American Indian women.

Prevalence and correlates of mental disorders among Native American women in primary care.

OBJECTIVES: We examined the lifetime and the past-year prevalence and correlates of common mental disorders among American Indian and Alaska Native women who presented for primary care. METHODS: We screened 489 consecutively presenting female primary care patients aged 18 through 45 years with the General Health Questionnaire, 12-item version. A subsample (n = 234) completed the Composite International Diagnostic Interview. We examined associations between psychiatric disorders and sociodemographic variables, boarding school attendance, and psychopathology in the family of origin. RESULTS: The study participants had high rates of alcohol use disorders, anxiety disorders, and anxiety/depression comorbidity compared with other samples of non-American Indian/Alaska Native women in primary care settings. CONCLUSIONS: There is a need for culturally appropriate mental health treatments and preventive services.

Panic disorder phenomenology in urban self-identified Caucasian-Non-Hispanics and Caucasian-Hispanics.

The epidemiology of panic disorder is well known, but data about some phenomenological aspects are sparse. The symptom criteria for panic disorder were developed largely from rational expert consensus methods and not from empirical research. This fact calls attention to the construct validity of the panic disorder diagnosis, which may affect accuracy of epidemiological findings. Seventy self-identified Non-Hispanic-Caucasian (Anglo) and Hispanic-Caucasian (Hispanic) people who were diagnosed with DSM-III-R panic disorder with or without agoraphobia were invited to complete a Panic Phenomenological Questionnaire (PPQ), which was constructed for this study from the Hamilton Anxiety Scale Items and The DSM-III-R panic symptoms. Fifty (71%) subjects agreed to participate, and there was no response bias detected. Seven symptoms on the PPQ that are not in the DSM-IV diagnostic criteria were reported to occur with a high prevalence in this study. Furthermore, many symptoms that occurred with a high frequency and were reported to be experienced as severe are also not included in current nosology. A few of the DSM-IV criterion symptoms occurred with low prevalence, frequency, and severity. Cognitive symptoms were reported to occur with higher frequency and severity during attacks than autonomic or other symptoms. There were modest differences between ethnic groups with regard to panic attack phenomena. Further research using multiple empirical methods aimed at improving the content validity of the panic disorder diagnosis is warranted. This includes utilizing consistent methods to collect data that will allow for rational decisions about how to construct valid panic disorder criteria across cultures.

Relationship between glycemic control, ethnicity and socioeconomic status in Hispanic and white non-Hispanic youths with type 1 diabetes mellitus.

OBJECTIVES: To determine if there is a disparity in glycemic control between Hispanic and white non-Hispanic children and adolescents with type 1 diabetes mellitus (DM) and to delineate the factors associated with glycemic control in these populations. STUDY DESIGN: This cross-sectional study included 183 youths with type 1 DM (99 white non-Hispanics and 84 Hispanics) and their parents/guardians cared for in a well-defined, private pediatric endocrine diabetes clinic, where the same physician and diabetes educators treat all patients. The youths were invited to participate if they had been diagnosed with diabetes at least 3 months before the study and were < 21 yr of age. Self-report questionnaires and chart reviews were used to assess individual familial and sociodemographic variables. OUTCOMES MEASURED: Mean hemoglobin A1c (HbA1c) levels, compliance with home monitoring of blood sugar, level of parental supervision of treatment, and socioeconomic status of Hispanic and white non-Hispanic families in the study. RESULTS: Hispanic youths with type 1 DM were in poorer metabolic control than their white non-Hispanic counterparts (0.45% difference in HbA1c levels, p = 0.02). Hispanic youths exhibited lower compliance with home monitoring of blood sugar but their parents reported greater supervision of their diabetes treatment. Hispanic families were found to have significantly lower income, rate of health insurance, father's educational attainment, and mother's educational attainment. Lower family socioeconomic status, but not ethnicity or educational attainment of parents, was associated with a significantly higher HbA1c, regardless of ethnicity. CONCLUSIONS: This study suggests that Hispanic youths with type 1 diabetes may be at greater risk for poor glycemic control because of their lower socioeconomic status rather than their ethnicity.

HbA(1c) levels among American Indian/Alaska Native adults.

OBJECTIVE: Type 2 diabetes is a major public health problem among many American Indian/Alaska Native communities. Elevated levels of HbA(1c) have been observed in younger American Indian/Alaska Native adults. The objectives of this study were: 1) to determine whether HbA(1c) levels were elevated among younger American Indian/Alaska Native adults nationally and, if so, 2) to determine the relationship between HbA(1c) levels and age due to treatment type, BMI, renal disease, duration of diabetes, survival, or a poor diabetes health care index. RESEARCH DESIGN AND METHODS: The national Indian Health Service Diabetes Care and Outcomes Audit was completed for a total of 11,419 American Indian/Alaska Native adults with type 2 diabetes from tribes across the U.S. in 1998. Glucose control was assessed by HbA(1c). BMI, diabetes duration, treatment type, and proteinuria were assessed from the Diabetes Care and Outcomes Audit data. To assess diabetes quality of care, an index was developed from six standard of care Diabetes Care and Outcomes Audit variables. RESULTS: We found HbA(1c) level decreased with increasing age. HbA(1c) levels were 9.2, 8.9, 8.8, 8.3, and 7.8 for ages 18-39, 40-49, 50-59, 60-69, and > or =70 years, respectively (P < 0.0001). This inverse relationship was not accounted for by differences in BMI, diabetes duration, treatment type, proteinuria, or health care index. CONCLUSIONS: Among American Indian/Alaska Native adults, HbA(1c) levels were highest in the youngest age-group. With increasing numbers of young American Indian/Alaska Native adults with diabetes, poorer glucose control is expected to bring concomitant increased morbidity and mortality unless more effective and efficient interventions are developed to improve glucose control among young American Indian/Alaska Native adults.

Regional variation in cardiovascular disease risk factors among American Indians and Alaska Natives with diabetes.

OBJECTIVE: To compare by region risk factors for cardiovascular disease among American Indian populations with diabetes. RESEARCH DESIGN AND METHODS: Trained providers from 185 federal, urban, and tribally operated facilities reviewed the records from systematic random samples of the patients included in the local diabetes registries in the 1998 Indian Health Service (IHS) Diabetes Care and Outcomes Audit. Selected measures of cardiovascular risk were aggregated by region and adjusted to calculate regional rates for patients <45 years of age (n = 2,595) and those aged > or =45 years (n = 8,294). RESULTS: Among the younger group of patients with diabetes, the rates of elevated HbA(1c) (> or =9%) and tobacco use varied significantly among regions. High rates of obesity (78%) and elevated HbA(1c) (56%) were found in the Southwest. High rates of tobacco use (55%) but the lowest rates of elevated HbA(1c) (27%) were found in Alaska. Among patients aged > or =45 years, all measures including rates of proteinuria, cholesterol > or =200 mg/dl, and mean blood pressure > or =130/85 varied significantly among all regions. Tobacco use was highest in the Great Lakes (44%) and Great Plains (42%) regions and lowest in the Southwest (14%) and Colorado Plateau (8%) regions. Proteinuria was found most frequently in the Southwest (35%), Colorado Plateau (30%), and Pacific regions (35%). Older individuals with diabetes were more likely than younger individuals to have proteinuria and blood pressure > or =130/85. CONCLUSIONS: American Indians and Alaska Natives with diabetes carry a large burden of potentially modifiable cardiovascular risk factors, but there is significant regional variation.
