Trends in alcohol consumption patterns among whites, blacks and Hispanics: 1984 and 1995

OBJECTIVE: To report national trends in alcohol consumption patterns among whites, blacks and Hispanics between 1984 and 1995, in relation to the recent decline in per capita consumption in the United States. METHOD: Data were obtained from two nationwide probability samples of U.S. households, the first conducted in 1984 and the second in 1995. The 1984 sample consisted of 1,777 whites, 1,947 blacks and 1,453 Hispanics; the 1995 sample consisted of 1,636 whites, 1,582 blacks and 1,585 Hispanics. On both occasions, interviews averaging 1 hour in length were conducted in respondents' homes by trained interviewers. RESULTS: Between 1984 and 1995, the rate of abstention remained stable among whites but increased among blacks and Hispanics. Frequent heavy drinking decreased among white men (from 20% to 12%), but remained stable among black (15% in both surveys) and Hispanic men (17% and 18%). Frequent heavy drinking decreased among white women (from 5% to 2%), but remained stable among black (5% in both surveys) and Hispanic women (2% and 3%). White men and women were two times more likely to be frequent heavy drinkers in 1984 than in 1995. CONCLUSIONS: The reduction in per capita consumption in the U.S. is differentially influencing white, black and Hispanic ethnic groups. The stability of rates of frequent heavy drinking places blacks and Hispanics at a higher risk for problem development than whites. This finding is, therefore, a concern to public health professionals and others interested in the prevention of alcohol-related problems among ethnic groups in the United States.     

Managed care and outcomes of hospitalization among elderly patients with congestive heart failure

123I-radiolabeled metaiodobenzylguanidine (123I-MIBG) cardiac imaging has been used to evaluate the distribution of sympathetic nervous system (SNS) in the heart. Different heart diseases have shown impaired cardiac SNS distribution as reflected by MIBG activity. The aim of this study was to assess the cardiac distribution of SNS in normal subjects, using MIBG imaging. Ten normal subjects (1 male and 9 females, mean age 46 +/- 9 years) with no cardiac abnormalities underwent myocardial 123I-MIBG scintigraphy, Tc-99m methoxyisobutylisonitrile (MIBI) cardiac perfusion imaging and equilibrium radionuclide angiography (RNA). Regional myocardial MIBG and MIBI activities were quantitatively evaluated using a region of interest analysis. For this purpose, the left ventricle was divided into 6 myocardial regions as anterior, apical, inferior, septum, lateral and posterolateral. In particular, myocardial MIBG and MIBI activities were measured as myocardium to mediastinum ratio. Regional left ventricular function was assessed by RNA. Myocardial MIBG uptake was homogeneous in anterior (2.2 +/- 0.5), inferior (2.5 +/- 0.7), septal (2.4 +/- 0.4), lateral (2.3 +/- 0.4), and posterolateral (2.3 +/- 0.4) regions. Conversely, MIBG uptake was significantly lower in the apical region (1.9 +/- 0.3) compared to all other left ventricular segments (p < 0.05). Regional myocardial perfusion, as measured by MIBI uptake, was homogeneous in all regions. No regional left ventricular wall motion abnormalities were observed by RNA. In conclusion, our data suggest that a decreased MIBG uptake may be observed in the left ventricular apical region of normal subjects reflecting reduced sympathetic innervation of the apex. This finding is not related to myocardial perfusion or wall motion abnormalities. The knowledge of cardiac sympathetic innervation in normal subjects may be helpful to assess SNS abnormalities in heart disease.     

A reassessment of self-disclosure patterns among Anglo-Americans and Hispanics.

Analyzed the Self-Disclosure Questionnaire responses of 155 Anglo-American and 119 Hispanic undergraduates according to overall frequency of reported self-disclosure, preferred topics (whether about taste, attitude, body, personality, or money) and preferred targets (whether to mother, father, male friend, female friend, or spouse). Examiner ethnicity and gender were systematically varied so that the interaction with S gender and ethnicity could be determined. Results reveal that females reported significantly more disclosure than males. Anglo-Americans indicated more disclosure than Hispanics, and disclosure among Hispanic males was particularly low. However, Hispanics reported high self-disclosure under some conditions. Specifically, Hispanic females reported high self-disclosure to female administrators, and Hispanic males reported significantly high self-disclosure with Hispanic female administrators. Ethnicity was not a significant factor in determining preferred topic and target of self-disclosure. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trends in alcohol-related mortality among New Mexico's American Indians, Hispanics, and non-Hispanic whites

Reduction of alcohol-related mortality is a national goal for health promotion and disease prevention. We conducted this analysis to determine whether trends in New Mexico's Hispanics, non-Hispanic Whites, and American Indians were consistent with national trends in alcohol-related mortality, and whether differences in drinking patterns could account for racial and ethnic differences in rates. Age-adjusted, race-specific, and ethnic-specific alcohol-related mortality rates and 95% confidence intervals were calculated for 5-year periods for 1958-1991 using New Mexico vital statistics data. We estimated the prevalence of acute and chronic at-risk drinking behaviors and abstinence from data collected by the Behavioral Risk Factor Surveillance System (BRFSS) for the period 1986-1992. We found that alcohol-related mortality rates varied substantially by race, ethnicity, sex, age, and calendar period. American Indians had the highest rates for both sexes. Rates increased sharply from the period 1958-1962 until the late 1970s and the early 1980s, and then began to decrease rapidly. However, during the most recent decade, the rates have followed contrasting trends in the three ethnic and racial groups. Although rates have continued to decline among non-Hispanic Whites, rates for Hispanics and American Indians have not declined, and still remain substantially higher than rates during the 1958-1962 period. Differences in at-risk drinking behaviors reported to the BRFSS do not explain the contrast in race-specific and ethnic-specific mortality rates. Although progress has been made in reducing national per capita alcohol consumption and alcohol-related mortality, certain high-risk racial and ethnic groups may not be sharing in the progress.     

Week-long hospitalization in a Department of Internal Medicine: patients and care patterns. Description and comparison with standard hospitalization

OBJECTIVES: The objective of this study was to determine the inpatient and care pathway predictive factors of week hospitalization (week-end excluded = HDS) compared to classical short term hospitalization (HC). METHODS: We compared 340 HDS stays to 65 HC stays. We analyzed the major in-patient sociodemographic and medical characteristics, and their care pathways. RESULTS: HDS inpatients were younger, more living in couples, had a higher educational level, better social insurance, more cancer, less associated diagnosis, less general health impairment than HC in-patients. More chemotherapies and endoscopies were performed in HDS. Hospital physicians were more often involved in HDS admissions than in HC admissions and general practitioners were more often involved in outpatient hospital visits for advice before HDS hospitalization than before HC hospitalization. HDS hospitalizations per in-patient were more numerous than HC hospitalizations. HDS inpatients were discharged directly to their home more often. After logistic regression modeling, most of these factors remained independently associated with HDS hospitalization, except for sociodemographic characteristics, age excluded, admission rates and home discharge. CONCLUSIONS: Type of hospitalization (HDS vs. HC) was mainly determined by medical characteristics of patients and by care pathways. Limiting factors were mainly due to organization of care.     

Comparison of an anticoagulation clinic with usual medical care: anticoagulation control, patient outcomes, and health care costs

BACKGROUND: The outcomes of an inception cohort of patients seen at an anticoagulation clinic (AC) were published previously. The temporary closure of this clinic allowed the evaluation of 2 more inception cohorts: usual medical care and an AC. OBJECTIVE: To compare newly anticoagulated patients who were treated with usual medical care with those treated at an AC for patient characteristics, anticoagulation control, bleeding and thromboembolic events, and differences in costs for hospitalizations and emergency department visits. RESULTS: Rates are expressed as percentage per patient-year. Patients treated at an AC who received lower-range anticoagulation had fewer international normalized ratios greater than 5.0 (7.0% vs 14.7%), spent more time in range (40.0% vs 37.0%), and spent less time at an international normalized ratio greater than 5 (3.5% vs 9.8%). Patients treated at an AC who received higher-range anticoagulation had more international normalized ratios within range (50.4% vs 35.0%), had fewer international normalized ratios less than 2.0 (13.0% vs 23.8%), and spent more time within range (64.0% vs 51.0%). The AC group had lower rates (expressed as percentage per patient-year) of significant bleeding (8.1% vs 35.0%), major to fatal bleeding (1.6% vs 3.9%), and thromboembolic events (3.3% vs 11.8%); the AC group also demonstrated a trend toward a lower mortality rate (0% vs 2.9%; P= .09). Significantly lower annual rates of warfarin sodium-related hospitalizations (5% vs 19%) and emergency department visits (6% vs 22%) reduced annual health care costs by $132086 per 100 patients. Additionally, a lower rate of warfarin-unrelated emergency department visits (46.8% vs 168.0%) produced an additional annual savings in health care costs of $29 72 per 100 patients. CONCLUSIONS: A clinical pharmacist-run AC improved anticoagulation control, reduced bleeding and thromboembolic event rates, and saved $162058 per 100 patients annually in reduced hospitalizations and emergency department visits.     

Incidence of spontaneous subarachnoid hemorrhage among Hispanics and non-Hispanic whites in New Mexico

Tri(gamma-glutamylcysteinylglycinyl)trithioarsenite (AsIII(GS)3) is formed in cells and is a more potent mixed-type inhibitor of the reduction of glutathione disulfide (GSSG) by yeast glutathione (GSH) reductase than either arsenite (AsIII) or GSH. The present work examines the effects of valence and complexation of arsenicals with GSH or L-cysteine (Cys) upon potency as competitive inhibitors of the reduction of GSH disulfide (GSSG) by yeast GSH reductase. Trivalent arsenicals were more potent inhibitors than their pentavalent analogs, and methylated trivalent arsenicals were more potent inhibitors than was inorganic trivalent As. Complexation of either inorganic trivalent As or methylarsonous diiodide (CH3As(III)I2) with Cys or GSH produced inhibitors of GSH reductase that were severalfold more potent than the parent arsenicals. In contrast, dimethylarsinous iodide ((CH3)2As(III)I) was a more potent inhibitor than its complexes with either GSH or Cys. Complexes of CH3AsIII with GSH (CH3-AsIII(GS)2) or with Cys (CH3AsIII(Cys)2) were the most potent inhibitors, with Ki's of 0.009 and 0.018 mM, respectively. Inhibition of GSH reductase by arsenicals or arsenothiols was prevented by addition of meso-2,3-dimercaptosuccinic acid (DMSA) to a mixture of enzyme, GSSG, and inhibitor before addition of NADPH. DMSA added to the reaction mixture after NADPH reversed inhibition by (CH3)2As(III)I but had little effect on inhibition by CH3As(III)I2, Ch3AsIII(GS)2, CH3AsIII(Cys)2, or AsIII(GS)3. Partial redox inactivation of the enzyme with NADPH increased the inhibitory potency of CH3As(III)I2 and (CH3)2As(III)I and changed the mode of inhibition for CH3As(III)I2 from competitive to noncompetitive. The greater potency of methylated trivalent arsenicals and arsenothiols than of inorganic trivalent As suggests that biomethylation of As could yield species that inhibit reduction of GSSG and alter the redox status of cells.     

Changes in drinking problems among whites, blacks, and Hispanics: 1984-1992

This paper reports changes in drinking problems among Whites, Blacks, and Hispanics between 1984 and 1992. A probability sample including 1,777 Whites. 1,947 Blacks, and 1,453 Hispanics in the United States adult household population was interviewed in 1984. In 1992 a subsample consisting of 788 Whites, 723 Blacks, and 703 Hispanics was reinterviewed. Results show a decrease in problem prevalence among Whites, stability among Blacks, and an increase among Hispanics. Problem incidence was higher among Hispanics than among Whites and Blacks, put problem remission was higher among Whites. Women had a lower problem incidence but a higher problem remission than men, independent of ethnicity. The two best predictors of problem status in 1992 were reporting a problem in 1984 and reporting a high level of consumption in 1984.     

Anesthesia providers, patient outcomes, and costs: a critique

The June 1996 article in Anesthesia and Analgesia by Abenstein and Warner entitled "Anesthesia Providers, Patient Outcomes, and Costs" presents important information about anesthesia services, but it contains a number of errors and questionable interpretations that could lead to inappropriate programs and policies. Among the most important points of fact we clarify in our paper are: 1. Three organizations that accredit, certify, and govern nurse anesthetists are organized in similar fashion to three comparable bodies governing anesthesiologists. There is no justification for the implication that the AANA somehow controls the accreditation and certification of CRNAs. 2. The conclusion that anesthesiologistled care teams are the preferred model for all anesthesia services and settings because of improved patient outcomes is overly simplistic and is not borne out in the literature. 3. The attribution of reduced mortality from anesthesia over the past 40 years to the increase in numbers of anesthesiologists is not justified. Many other factors, including new anesthetic agents and improved patient monitoring, also are important. 4. The use of a hypothetical example related to Medicare reimbursement in New York to justify the implication that CRNA-delivered services are more costly than anesthesiologist-delivered services is misleading and not borne out in the literature. We hope that planners and policy makers will read the article by Abenstein and Warner with extreme caution. Taking some of their statements and conclusions seriously could lead to policies and programs that are not focused in science.     

Relationship of provider characteristics to outcomes, process, and costs of care for community-acquired pneumonia

OBJECTIVES: The authors describe the relation of provider characteristics to processes, costs, and outcomes of medical care for elderly patients hospitalized for community-acquired pneumonia. METHODS: Using Medicare claims data, Medicare beneficiaries discharged from Pennsylvania hospitals during 1990 with community-acquired pneumonia were identified. Claims data were used to ascertain mortality, readmissions, use of procedures and physician consultations, and the costs of care. The relationship of these measures to provider characteristics was analyzed using regression techniques to adjust for patient characteristics, including comorbidity and microbial etiology. RESULTS: Among 22,294 pneumonia episodes studied, 30-day mortality was 17.0%. After adjusting for patient characteristics, 30-day mortality and readmission rates were unrelated to hospital teaching status or urban location or to physician specialty. Use of procedures and physician consultations was more common and costs were 11% higher among patients discharged from teaching hospitals compared with nonteaching hospitals. Similarly, costs were 15% higher at urban hospitals compared with rural hospitals. General internists and medical subspecialists used more procedures and had higher costs than family practitioners. CONCLUSIONS: Processes and costs of care for community-acquired pneumonia varied by provider characteristics, but neither mortality nor readmission rates did. These differences cannot be explained by clinical variables in the database. Further studies should determine whether less costly patterns of care for pneumonia, and perhaps other conditions, could replace more costly ones without compromising patient outcomes.     

Health care costs of obesity in New Zealand

We studied the effects of 6-chloro-2',3'-dideoxyguanosine (6-Cl-ddG), an antiretroviral drug, in surface lymph nodes of rhesus monkeys (Macaca mulatta) chronically infected with simian immunodeficiency virus (SIV). The rhesus monkeys were treated with 25 mg/kg of 6-Cl-ddG every 8 hr for 2 weeks. We performed sequential biopsies of the surface lymph nodes three times: before, during, and after the drug treatment. The 6-Cl-ddG dramatically decreased the number of infectious virus (measured by limiting dilution assay) in lymph node mononuclear cells. This decrease was consistent with the decrease in the number of viral RNA-positive cells in lymph nodes (analyzed by in situ hybridization). Histopathological analysis revealed that hyperplastic lymphoid follicles were reduced in size, especially, enlarged areas of centroblasts in lymphoid follicles (the so-called dark areas of germinal centers) were declined. Our results demonstrated that 6-Cl-ddG decreased the viral burden concomitantly with reduced hyper-activation of germinal centers in lymphoid follicles of SIV-infected rhesus monkeys.     

Patients readmitted to the intensive care unit during the same hospitalization: clinical features and outcomes

OBJECTIVE: To determine the clinical features and outcomes of patients readmitted to the intensive care unit (ICU) during the same hospital stay and the causes for these readmissions. DESIGN: Multicenter, cohort study. SETTING: Three ICUs from two teaching hospitals and four ICUs from four community hospitals. PATIENTS: All ICU admissions were collected prospectively for a registry database in the seven ICUs. We retrospectively analyzed ICU admissions between January 1, 1995 and February 29, 1996. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the study period, 236 (4.6%) of the patients discharged alive from the ICU were readmitted to the unit. Patients with gastrointestinal (GI) and neurologic diagnoses had the highest readmission rate. Of the readmissions, 45% had recurrence of the initial disease, 39% experienced new complications, and 14% required further planned operation. Among patients readmitted for the same illness, cardiovascular and respiratory problems were the most frequent diagnoses. Of patients readmitted with a new diagnosis, 30% initially had GI diseases, while respiratory diseases accounted for 58% of the new complications. Readmissions within 24 hrs occurred in 27% of all readmissions. Patients requiring readmission had a higher hospital mortality rate (31.4%) compared with those not requiring readmission (4.3%, p < .001), even after adjustment for disease severity score (odds ratio = 5.93, p < .001). CONCLUSIONS: Patients with GI and neurologic diseases are at greatest risk of requiring ICU readmission. Respiratory diseases are the major reason for readmission due to new complications. Readmitted patients have a high risk of hospital death that may be underestimated by the usual physiologic indicators on either initial admission or readmission. Further studies are required to determine if patients at risk for readmission can be identified early to improve the outcome.     

Risk of emergency care, hospitalization, and ICU stays for acute asthma among recipients of salmeterol

We used automated health insurance claims records of a New England insurer to assess the relation between salmeterol and severe nonfatal asthma. We identified 61,712 members who received a beta-agonist from January 1, 1993 to August 31, 1995, including 2, 708 recipients of salmeterol. Compared with recipients of other beta-agonists, future salmeterol recipients had higher rates of asthma hospitalization and dispensings of asthma medications during the year before they received salmeterol. We selected as a comparison group 3,825 recipients of sustained-release theophylline. We defined a baseline period as the year before the start of the follow-up period, and we characterized patients according to age, sex, calendar period, presence of baseline hospitalizations for asthma, presence of chronic obstructive pulmonary disease (COPD), and baseline dispensings of asthma medications. After adjusting for baseline factors, incidence rates of severe asthma in the salmeterol group were not elevated for emergency care (rate ratio estimate [RR] = 0.69, 95% confidence intervals [CI] = 0.42, 1.11), hospitalization (RR = 1.09, 95% CI = 0.60, 1.98), or intensive care unit (ICU) stays (RR = 0.81, 95% CI = 0.25, 2.62). We conclude that salmeterol was prescribed preferentially to high-risk patients and, after adjusting for baseline risk, salmeterol recipients did not have a greater risk than theophylline recipients of severe nonfatal asthma.     

New Mexico women with no prenatal care: reasons, outcomes, and nursing implications

A retrospective chart review was conducted to determine why women received no prenatal care during pregnancy and their subsequent maternal and neonatal outcomes. Five hundred and eighty medical records from 1990 through 1993 that were labeled as no care were reviewed. Actually, only 270 records had no care and of these, 92 had 156 recorded reasons as to why women did not receive prenatal care. These reasons were categorized into three types of barriers: attitudinal, sociodemographic, and system-related. The majority of the women were young, Hispanic, unmarried, between 20 and 29 years of age, and uninsured, and had one to three children. Overall, the women did not smoke cigarettes, drink alcohol, or use drugs during pregnancy. Overall, the women had good maternal and newborn outcomes. Results suggest a need to reevaluate the effect of prenatal care use on young Hispanic women.     

Heparin-bonded circuits: clinical outcomes and costs

The aim of this study was to use meta-analysis to combine the results of numerous studies and examine the impact of heparin-bonded circuits on clinical outcomes and the resulting costs. Heparin-bonded circuits, both ionically and covalently bonded, are examined separately. The results of the study provide evidence that heparin-bonded circuits result in improved clinical outcomes when compared to the identical nonheparin-bonded circuits. These improved clinical outcomes result in subsequent lower costs per patient with their use. However, differences are apparent in the significance and magnitude of these outcomes between ionically and covalently bonded circuits. Covalently bonded circuits provide a greater magnitude and significance of improvement in clinical outcomes than ionically bonded circuits. Total cost savings can be expected to be three times greater with covalently bonded circuits ($3231 versus $1068). It was concluded that the choice regarding the use of a heparin-bonded circuits and the type of heparin-bonded circuit used has the potential to alter clinical outcomes and subsequent costs. Cost consideration cannot be ignored, but clinical benefits should be the main rationale for the choice of cardiopulmonary bypass circuit. This analysis provides evidence that clinical benefits and cost savings can both be derived from use of the same technology-covalently bonded circuits.     

Psychosocial costs of racism to Whites: Understanding patterns among university students.

This investigation adds to the growing body of scholarship on the psychosocial costs of racism to Whites (PCRW), which refer to consequences of being in the dominant position in an unjust, hierarchical system of societal racism. Extending research that identified 5 distinct constellations of costs of racism (L. B. Spanierman, V. P. Poteat, A. M. Beer, & P. I. Armstrong, 2006), the authors used multinomial logistic regression in the current study to examine what factors related to membership in 1 of the 5 PCRW types during the course of an academic year. Among a sample of White university freshmen (n = 287), the authors found that (a) diversity attitudes (i.e., universal diverse orientation and unawareness of privilege) explained PCRW type at entrance, (b) PCRW type at entrance explained participation in interracial friendships at the end of the year, (c) 45% of participants changed PCRW type during the course of the year, and (d) among those who changed type, particular PCRW types at entrance resulted in greater likelihood of membership in particular PCRW types at the end of the year.

Comparative outcomes and costs of inpatient care and supportive housing for substance-dependent veterans

OBJECTIVE: This study examined the differential effectiveness and costs of three weeks of treatment for patients with moderately severe substance dependence assigned to inpatient treatment or to a supportive housing setting. Supportive housing is temporary housing that allows a patient to participate in an intensive hospital-based treatment program. Type and intensity of treatment were generally equivalent for the two groups. METHODS: Patients were consecutive voluntary admissions to the substance abuse treatment program of a large metropolitan Veterans Affairs medical center. Patients with serious medical conditions or highly unstable psychiatric disorders were excluded. Patients in supportive housing attended the inpatient program on weekdays from 7:30 a.m. to 5 p.m. They were assessed at baseline and at two-month follow-up. RESULTS: Baseline analyses of clinical, personality, and demographic characteristics revealed no substantive differences between the 62 patients assigned to inpatient treatment and the 36 assigned to supportive housing. The degree of treatment involvement and dropout rates did not differ between groups. Of the 55 inpatients completing treatment, 29 were known to be abstinent at follow-up, and of the 35 supportive housing patients completing treatment, 22 were abstinent. The proportion was similar for both groups, about 70 percent. The cost of a successful treatment for the inpatient group was $9,524. For the supportive housing group, it was $4,291. CONCLUSIONS: Given the absence of differential treatment effects between inpatient and supportive housing settings, the use of supportive housing alternatives appears to provide an opportunity for substantial cost savings for VA patients with substance dependence disorders.
