The association between neighborhood socioeconomic status and ovarian cancer tumor characteristics.

PURPOSE: Higher pathologic grade, suboptimal debulking surgery, and late-stage are markers of more aggressive and advanced ovarian cancer. Neighborhood socioeconomic status (SES) has been associated with more aggressive and advanced tumors for other cancer sites, and this may also be true for ovarian cancer. METHODS: We examined the association between neighborhood SES and ovarian cancer tumor characteristics using data on 581 women diagnosed with epithelial ovarian cancer in Cook County, Illinois. Two complementary measures (concentrated disadvantage and concentrated affluence) were used to estimate neighborhood SES. Prevalence differences and 95 % confidence intervals were estimated in logistic regression models adjusted for age and race. RESULTS: Greater disadvantage was associated with higher grade tumors (p = 0.03) and suboptimal debulking (p = 0.05) and marginally associated with later tumor stage (p = 0.20). Greater affluence was inversely associated with stage at diagnosis (p = 0.004) and suboptimal debulking (p = 0.03) and (marginally) with tumor grade (p = 0.21). CONCLUSION: Our findings suggest that lower SES, estimated by neighborhood SES, is associated with ovarian cancer tumor characteristics indicative of more advanced and aggressive disease.

School and Behavioral Outcomes Among Inner City Children: Five-Year Follow-Up.

Educational achievement is a key determinant of future life chances, but children growing up in poverty tend to do worse by many academic measures. Family, school, and neighborhood contextual characteristics may affect academic outcomes. In an attempt to explore neighborhood and individual level factors, we performed multilevel analyses to explain child's behavioral problems, repeat grade, average math and reading scores. Outcome measures were associated with specific neighborhood characteristics, above and beyond the effect of student/family level factors. The findings warrant further consideration of ecological interventions aiming to improve academic and behavioral outcomes of children living in poverty.

Gender differences in baseline health, needs at release, and predictors of care engagement among HIV-positive clients leaving jail.

Women represent a significant and growing segment of jail detainees and persons living with HIV. This paper examines gender differences in health status, care and social service needs, and care engagement among jail releasees with HIV. Data are from 1,270 participants in the HRSA-funded Enhancing Linkages to HIV Primary Care and Social Services multisite demonstration project (EnhanceLink). Compared to men, more women reported homelessness, reduced adherence to prescribed ART, worse health, more severe substance use disorders, and more chronic health conditions. Men and women generally reported different needs post-release. As the number of expressed needs increased, women were more likely to drop out of care. Our findings suggest that effective and gender-specific strategies are required to identify needs, link services between jails and communities, and sustain retention of women with HIV in programs after release from criminal justice settings.

Risk factors for homelessness and sex trade among incarcerated women: A Structural equation model.

Incarcerated women are among the most vulnerable and perhaps the least studied populations in the US. Significant proportions of female inmates are substance users, and many living in unstable housing conditions or being homeless. Female inmates are often at high risk of engaging in sex exchange for drugs or housing needs. While a disproportionate number of incarcerated women have experienced childhood household adversities and maltreatments, the effects of these childhood experiences on psychosocial and behavioral outcomes of this population in later life. We apply a life course perspective to examine these pathways in a sample of incarcerated women in Cook County, Illinois. Findings demonstrated lasting, but differential, effects of household adversities and childhood abuse on subsequent life risks and opportunities among these women.

Effect of education on hand hygiene beliefs and practices: a 5-year program.

To evaluate infection control and hand hygiene understanding at 3 public hospitals, we surveyed 4,345 healthcare workers (HCWs) 3 times during a 5-year infection control intervention. The preference for the use of alcohol hand rub for hand hygiene increased dramatically; in nurses, it increased from 14% to 34%; in physicians, 4.3% to 51%; and in allied HCWs, 12% to 44%. Study year, infection control interactive education-session attendance, infection control knowledge, and being a physician or allied HCW independently predicted a preference for alcohol hand rub.

Effects of human immunodeficiency virus on protracted amenorrhea and ovarian dysfunction.

OBJECTIVE: To characterize ovarian failure and prolonged amenorrhea from other causes in women who are both human immunodeficiency virus (HIV) seropositive and seronegative. METHODS: This was a cohort study nested in the Women's Interagency HIV Study, a multicenter U.S. study of HIV infection in women. Prolonged amenorrhea was defined as no vaginal bleeding for at least 1 year. A serum follicle stimulating hormone more than 25 milli-International Units/mL and prolonged amenorrhea were used to define ovarian failure. Logistic regressions, chi2, and t tests were performed to estimate relationships between HIV-infection and cofactors with both ovarian failure and amenorrhea from other causes. RESULTS: Results were available for 1,431 women (1,139 HIV seropositive and 292 seronegative). More than one half of the HIV positive women with prolonged amenorrhea of at least 1 year did not have ovarian failure. When adjusted for age, HIV seropositive women were about three times more likely than seronegative women to have prolonged amenorrhea without ovarian failure. Body mass index, serum albumin, and parity were all negatively associated with ovarian failure in HIV seropositive women. CONCLUSION: HIV serostatus is associated with prolonged amenorrhea. It is difficult to ascertain whether the cause of prolonged amenorrhea is ovarian in HIV-infected women without additional testing. LEVEL OF EVIDENCE: II-2.

Ability of practitioners to identify solid oral dosage tablets.

PURPOSE: Physicians' and pharmacists' ability to correctly identify three commonly used oral dosage forms was assessed. METHODS: A list of physicians and pharmacists was obtained from two urban teaching hospitals. A total of 100 pharmacists and physicians were randomly selected and their ability to correctly identify three commonly used tablets was tested. Participants were also asked about their experiences and views on current resources and alternatives for identifying oral dosage forms. Tablet-identification exercises were performed by physicians and pharmacists in their usual practice settings. Participants could consult the resources usually available to them for the identification of unknown medications. RESULTS: A total of 300 observations were made in the tablet-identification exercise (100 participants, three tablets per participant). The tablet was correctly identified in 190 of the observations (63%). The brand-name tablet, the generic tablet, and the nonprescription generic tablet were correctly identified in 78%, 64%, and 48% of the observations, respectively. Only 18 physicians (36%) and 24 pharmacists (48%) correctly identified all three tablets, whereas 10 physicians (20%) and 5 pharmacists (10%) could not correctly identify any of the tablets. The mean time required to identify a tablet was 3.65 minutes. Pharmacists most often used electronic resources (52%), while physicians relied on print resources. Overall, 77% expressed dissatisfaction with the current system and 91% favored a universal imprint coding system for oral dosage forms. CONCLUSION: Physicians and pharmacists failed to correctly identify three commonly prescribed tablets more than a third of the time. The brand-name tablet was correctly identified more often than were the prescription generic and nonprescription generic products.

Missed hypothyroidism diagnosis uncovered by linking laboratory and pharmacy data.

BACKGROUND: Although diagnostic errors are important, they have received less attention than medication errors. Timely follow-up of abnormal laboratory test results represents a critical aspect of the diagnostic process, and failures at this step are a cause of delayed or missed diagnosis, resulting in suboptimal clinical outcomes and malpractice litigation. We linked laboratory and pharmacy databases to (1) explore the potential for linking laboratory and pharmacy databases to uncover diagnostic errors, and (2) determine the frequency of failed follow-up of elevated levels of thyroid-stimulating hormone (TSH). METHODS: We downloaded TSH test results for 2 consecutive years from a laboratory database and linked this database with a pharmacy database to screen for patients with TSH levels of 20 mU/mL or higher who were not receiving levothyroxine. Patients with elevated TSH levels lacking prescriptions were followed up by telephone and record review. RESULTS: During the 2-year period, 982 (2.7%) of 36 760 unique patients tested for TSH level had elevated TSH levels. Of these patients, 177 (18.0%) had no recorded levothyroxine prescriptions. We attempted to contact 177 patients with high TSH levels who were not taking thyroid medications and reached 123 (69.5%). Of the 123 patients we were able to reach, 12 in 2000 and 11 in 2001 were unaware of their abnormal test results or a diagnosis of hypothyroidism, representing 2.3% of 982 patients with elevated TSH levels. We were unable to reach another 54 patients (5.5% of the total number of patients with elevated TSH levels) by either telephone or mail. CONCLUSIONS: By linking laboratory and pharmacy databases, we uncovered patients who did not undergo follow-up for abnormal TSH results. Conservatively, there was no follow-up for abnormal TSH results in more than 2% of patients, and another 5% of patients were lost to follow-up and possibly unaware of their results. Uncovering patients with missed diagnosis illustrates a potential use of linking laboratory and pharmacy databases to identify vulnerabilities in the care system and improve patient safety.

The effect of neighborhood disadvantage on the racial disparity in ovarian cancer-specific survival in a large hospital-based study in cook county, illinois.

This paper examines the effect of neighborhood disadvantage on racial disparities in ovarian cancer-specific survival. Despite treatment advances for ovarian cancer, survival remains shorter for African-American compared to White women. Neighborhood disadvantage is implicated in racial disparities across a variety of health outcomes and may contribute to racial disparities in ovarian cancer-specific survival. Data were obtained from 581 women (100 African-American and 481 White) diagnosed with epithelial ovarian cancer between June 1, 1994, and December 31, 1998 in Cook County, IL, USA, which includes the city of Chicago. Neighborhood disadvantage score at the time of diagnosis was calculated for each woman based on Browning and Cagney's index of concentrated disadvantage. Cox proportional hazard models measured the association of self-identified African-American race with ovarian cancer-specific survival after adjusting for age, tumor characteristics, surgical debulking, and neighborhood disadvantage. There was a statistically significant negative association (-0.645) between ovarian cancer-specific survival and neighborhood disadvantage (p = 0.008). After adjusting for age and tumor characteristics, African-American women were more likely than Whites to die of ovarian cancer (HR = 1.59, p = 0.003). After accounting for neighborhood disadvantage, this risk was attenuated (HR = 1.32, p = 0.10). These findings demonstrate that neighborhood disadvantage is associated with ovarian cancer-specific survival and may contribute to the racial disparity in survival.

Sociodemographic Characteristics, Distance to the Clinic, and Breast Cancer Screening Results.

Timely detection and follow-up of abnormal cellular changes can aid in early diagnosis of breast cancer, thus leading to better treatment outcomes. However, despite substantial breast cancer screening initiatives, the proportion of female breast cancer cases diagnosed at late stages remains high. Distance to screening clinics may affect access to care, particularly for women living in impoverished areas with limited means of reliable transportation. Utilizing breast cancer screening data collected by the Illinois Breast and Cervical Cancer Program between 1996 and 2010, we examined the effect of travel distance to the clinic from which women received breast cancer screening tests on stage of diagnosis. The proportion of abnormal mammograms in White women (1.6%) was higher than in Black women (1.1%) or Hispanic women (0.5%). The average distance traveled to a clinic was also farthest among White women (6.7 mi) than for Hispanic (5.3 mi) or Black women (4.4 mi). Distance to a clinic was significantly associated with increased odds of having abnormal results. When distance to clinic was controlled for, the observed disparity in odds of having an abnormal mammogram between White and Black women was no longer statistically significant. Individual and neighborhood sociodemographic characteristics were significantly associated with distance to clinic, but were not associated with increased odds of having an abnormal mammogram, controlling for distance to the clinic. Findings showed that individual and neighborhood sociodemographic characteristics are directly and indirectly associated with abnormal mammogram results, and that distance to a clinic may mediate, in part, the effects of individual characteristics and neighborhood disadvantage on the probability of having an abnormal mammogram.

Utilizing Exploratory Spatial Data Analysis to Examine Health and Environmental Disparities in Disadvantaged Neighborhoods.

Health disparities research has focused primarily on racial and socioeconomic differences in health outcomes. Although neighborhood characteristics and the concept of built environment have been shown to affect individual health, measuring the effects of environmental risks on health has been a less developed area of disparities research. To examine spatial associations and the distribution of geographic patterns of sociodemographic characteristics, environmental cancer risk, and cancer rates, we utilized existing data from multiple sources. The findings from our initial analysis, which concerned with proximity to environmental hazards and at-risk communities, were consistent with results of previous studies, which often reported mixed relationships between health disparity indicators and environmental burden. However, further analysis with refined models showed that several key demographic and subdomains of cancer risk measures were shown to have spatial components. With the application of exploratory spatial data analysis, we were able to identify areas with both high rates of poverty and racial minorities to further examine for possible associations to environmental cancer risk. Global spatial autocorrelation found spatial clustering with percent black, percent poverty, point and non-point cancer risks requiring further spatial analysis to determine relationship of significance based on geography. This methodology was based upon particular assumptions associated with data and applications, which needed to be met. We conclude that careful assessment of the data and applications were required to properly interpret the findings in understanding the relationship between vulnerable populations and environmental burden.

Racial differences in stage at diagnosis and survival from epithelial ovarian cancer: a fundamental cause of disease approach.

Associations between race, socioeconomic status (SES) and health outcomes have been well established. One of the ways in which race and SES affect health is by influencing one's access to resources, which confers ability to avoid or mitigate adverse outcomes. The fundamental cause of disease approach argues that when a new screening tool is introduced, individuals with greater resources tend to have better access to the innovation, thus benefiting from early detection and leading to better survival. Conversely, when there is no established screening tool, racial and SES differences in early detection may be less pronounced. Most ovarian cancer is diagnosed at advanced stages, because of the lack of an effective screening tool and few early symptoms. However, once detected, racial differences may still be observed in mortality and survival outcomes. We examined the racial differences in diagnosis and survival among ovarian cancer cases diagnosed during 1994-1998, in Cook County, Illinois (N = 351). There were no racial differences in the stage at diagnosis: 51.7% of white and 52.9% of black women were diagnosed at later stages (III and IV). Only age was associated with the stage at diagnosis. Tumor characteristics also did not differ between white and black women. Compared to white women, black women were less likely to be married, less educated, more frequently used genital powder, had tubal ligation, and resided in higher poverty census tracts. As of December 31, 2005, 44.3% of white and 54.5% of black women had died of ovarian cancer. Controlling for known confounding variables, the hazard ratio for ovarian cancer death between black and white women was 2.2. The findings show that fundamental cause perspective provides a potential framework to explore subtleties in racial disparities, with which broader social causes may be accounted for in explaining post diagnosis racial differences.

Prediagnosis food patterns are associated with length of survival from epithelial ovarian cancer.

BACKGROUND: Dietary factors have been the focus of many studies on the etiology of ovarian cancer and may potentially affect survival. Indeed, three recent studies outside the United States have suggested that diet plays a role in ovarian cancer survival. OBJECTIVE: The study purpose was to evaluate the hypothesis that women diagnosed with ovarian cancer whose reported prediagnosis food patterns more closely reflect recommendations for optimal health experience a survival advantage compared with those reporting poorer diets. DESIGN: A longitudinal follow-up study design was used to examine prediagnosis usual diet effects on survival among 341 Cook County, Illinois, residents diagnosed with epithelial ovarian cancer during 1994-1998. These women participated in a previous case-control study where diet was assessed using a validated food frequency questionnaire. This diet information was categorized utilizing the Dietary Guidelines for Americans 2005. Deaths through 2005 were ascertained using a national death index search. STATISTICAL ANALYSIS: Hazard ratios (HR) and 95% confidence intervals (CI) adjusting for important covariables were obtained from proportional hazards regression models to evaluate diet effects on survival from ovarian cancer. RESULTS: Comparisons of high to low food group or subgroup intakes demonstrated statistically significant prediagnosis food pattern associations with survival time. Longer survival was associated with total fruits and vegetables (HR 0.61, 95% CI 0.38 to 0.98, P for trend=0.10) and vegetables separately (HR 0.66, 95% CI 0.43 to 1.01, P for trend <0.05). Subgroup analyses showed only yellow and cruciferous vegetables to significantly favor survival. Conversely, a survival disadvantage was shown for meats, not generally recommended (HR 2.28, 95% CI 1.34 to 3.89, P for trend <0.01), and specifically the red and cured/processed meats subgroups. An increased HR was also observed for the milk (all types) subgroup (HR 2.15, 95% CI 1.20 to 3.84, P for trend <0.05). CONCLUSIONS: Prediagnosis adherence to diets that reflect recommendations for optimal nutrition and cancer prevention may have benefits that continue even after an ovarian cancer diagnosis.

Diagnostic error in medicine: analysis of 583 physician-reported errors.

BACKGROUND: Missed or delayed diagnoses are a common but understudied area in patient safety research. To better understand the types, causes, and prevention of such errors, we surveyed clinicians to solicit perceived cases of missed and delayed diagnoses. METHODS: A 6-item written survey was administered at 20 grand rounds presentations across the United States and by mail at 2 collaborating institutions. Respondents were asked to report 3 cases of diagnostic errors and to describe their perceived causes, seriousness, and frequency. RESULTS: A total of 669 cases were reported by 310 clinicians from 22 institutions. After cases without diagnostic errors or lacking sufficient details were excluded, 583 remained. Of these, 162 errors (28%) were rated as major, 241 (41%) as moderate, and 180 (31%) as minor or insignificant. The most common missed or delayed diagnoses were pulmonary embolism (26 cases [4.5% of total]), drug reactions or overdose (26 cases [4.5%]), lung cancer (23 cases [3.9%]), colorectal cancer (19 cases [3.3%]), acute coronary syndrome (18 cases [3.1%]), breast cancer (18 cases [3.1%]), and stroke (15 cases [2.6%]). Errors occurred most frequently in the testing phase (failure to order, report, and follow-up laboratory results) (44%), followed by clinician assessment errors (failure to consider and overweighing competing diagnosis) (32%), history taking (10%), physical examination (10%), and referral or consultation errors and delays (3%). CONCLUSIONS: Physicians readily recalled multiple cases of diagnostic errors and were willing to share their experiences. Using a new taxonomy tool and aggregating cases by diagnosis and error type revealed patterns of diagnostic failures that suggested areas for improvement. Systematic solicitation and analysis of such errors can identify potential preventive strategies.

Treatment completion among TB patients returned to the community from a large urban jail.

Despite the current decline of TB in the general population, the prevalence of TB remains conspicuously higher among inmates. While treatment completion is a key to controlling and preventing drug-resistant TB, it is difficult to be achieved among incarcerated populations due to their social, economic, and behavioral characteristics. This article examined factors associated with treatment completion among jail inmates with TB disease after their return to the community. Retrospective analyses were performed to explore the relationships between demographic, behavioral, incarceration factors, and treatment methods with treatment completion. Hispanics (vs. blacks), those who had children, and those incarcerated for simple charges (vs. drug related charges) were less likely to complete treatment. DOT users were more likely to complete treatment then those who used the self administration method. Inmates whose DOT was administered at a field site were more likely to complete treatment than those whose DOT took place at a clinic or mixed clinic and field. Although mixed DOT might be less expensive than field DOT, it represented no significant improvement over clinic DOT. Treatment methods must employ an outreach strategy to meet each patient's need, considering the broader socioeconomic context.

Deaths in the Cook County jail: 10-year report, 1995-2004.

The aims of this study were to describe causes of death during the 10-year period between 1995 and 2004 in a large urban jail in Chicago; to compare disease specific mortality rates between the jail population and the general population; to explore demographic and incarceration characteristics of the inmates who died in the jail by cause of death; and to examine gender difference in demographic characteristics, incarceration patterns, and causes of death. A total of 178 deaths occurring in the jail over a 10-year period (1995-2004) were reviewed. Age-adjusted disease-specific mortality rates were computed for the jail population and compared with the rates in the US general population. Cause of death, demographic variables, and incarceration related factors were retrieved from multiple computerized databases. Descriptive analyses were performed to examine demographic and incarceration-related patterns by cause of death and gender. Heart disease was the most frequent cause of death in the jail population, followed by cerebrovascular disease and suicide. Mortality rates for heart diseases, infectious/inflammatory conditions and suicide were higher for jail inmates than the general population. Black inmates accounted for the majority of deaths due to illnesses and homicide, and a much higher proportion of white and Hispanic inmates were involved in suicide deaths. Deaths due to drug overdose or withdrawal were disproportionately higher among female inmates compared with male inmates. Consistent review of mortality rates and causes of deaths in jail can be a useful tool to better understand health issues and needs of jail inmates. Surveillance of acute and chronic illnesses and strategic reengineering of jail health care is a key to quality improvement for incarcerated populations for whom the jail system becomes their primary care provider.

Risk factors for tuberculosis among inmates: a retrospective analysis.

This paper examined risk factors associated with TB among inmates, over a 7-year period, and the association of ethnicity and gender with these risk factors. We performed retrospective analysis of data on former inmates from a county jail. TB status at admission was explained with demographics, behavioral risk factors, and incarceration factors. We examined ethnicity and gender defenses on the risk factors. A total of 441 TB cases and 478 non-TB cases were included. Inmates were more likely to have TB if they were whites, unmarried, homeless, alcohol abusers, and HIV positive. Inmates with TB had even lower socioeconomic status and more behavioral risk factors than other inmates. They had fewer incarcerations and less serious crimes, but longer jail stays. TB risk factors differed by ethnicity and gender. TB control in jails requires intervention in the communities where inmates live. Correctional health is a critical part of public health. Public health nurses are responsible for better understanding and improving health care for this high-risk and difficult-to-reach population.
