Associations of self-reported oral health with physical and mental health in a nationally representative sample of HIV persons receiving medical care.

BACKGROUND: The impact of oral health on HIV patients has not been sufficiently documented. OBJECTIVE: To estimate the associations between measures of oral and generic health-related quality of life in persons receiving medical care for HIV. DESIGN: This is a longitudinal study of interview data collected in a probability sample of adults with HIV receiving health care in the US. The data were collected at three points in time. PATIENTS: Two thousand eight hundred and sixty-four HIV-infected adults using medical care. MEASUREMENTS: Physical and mental health were assessed using 28 items and oral health was assessed using seven items on oral-related pain and discomfort, worry, appearance, and function. Clinical measures included CD4 count, oral symptoms, physical symptoms, and stage of HIV. Physical functioning and emotional well-being were measured on a 0-100 scale with higher scores indicating better health. Oral health was measured using seven items with a five point scale. RESULTS: In multivariate analyses, oral symptoms had the strongest association with oral health-related quality of life. Each additional oral symptom was associated with an average decrease in oral health (0-100 possible range) of 3.97 points (p = 0.000). In addition, oral health was significantly associated with both physical and mental health. A one-point increase in oral health was associated with a 0.05 (p = 0.000) increase in mental health and 0.02 increase in physical health (p = 0.031). CONCLUSIONS: Oral health is strongly associated with physical and mental health but provides noteworthy unique information in persons with HIV infection. Thus, physical and mental health measures of HIV patients should incorporate indicators of oral functioning and well-being.

Effect of case management on unmet needs and utilization of medical care and medications among HIV-infected persons.

BACKGROUND: Although case management has been advocated as a method for improving the care of chronically ill persons, its effectiveness is poorly understood. OBJECTIVE: To assess the effect of case managers on unmet need for supportive services and utilization of medical care and medications among HIV-infected persons. DESIGN: Baseline and follow-up interview of a national probability sample. SETTING: Inpatient and outpatient medical facilities in the United States. PARTICIPANTS: 2437 HIV-infected adults representing 217 081 patients receiving medical care. MEASUREMENTS: Outcomes measured at follow-up were unmet need for supportive services, medical care utilization (ambulatory visits, emergency department visits, and hospitalizations), and use of HIV medication (receipt of antiretroviral therapy and prophylaxis against Pneumocystis carinii pneumonia and toxoplasmosis). RESULTS: At baseline, 56.5% of the sample had contact with a case manager in the previous 6 months. In multiple logistic regression analyses that adjusted for potential confounders, contact with a case manager at baseline was associated with decreased unmet need for income assistance (odds ratio [OR], 0.57 [95% CI, 0.36 to 0.91]), health insurance (OR, 0.54 [CI, 0.33 to 0.89]), home health care (OR, 0.29 [CI, 0.15 to 0.56]), and emotional counseling (OR, 0.62 [CI, 0.41 to 0.94]) at follow-up. Contact with case managers was not significantly associated with utilization of ambulatory care (OR, 0.77 [CI, 0.57 to 1.04]), hospitalization (OR, 1.13 [CI, 0.84 to 1.54]), or emergency department visits (OR, 1.30 [CI, 0.97 to 1.73]) but was associated with higher utilization of two-drug (OR, 1.58 [CI, 1.23 to 2.03]) and three-drug (OR, 1.34 [CI, 1.00 to 1.80]) antiretroviral regimens and of treatment with protease inhibitors or non-nucleoside reverse transcriptase inhibitors (OR, 1.29 [CI, 1.02 to 1.64]) at follow-up. CONCLUSIONS: Case management appears to be associated with fewer unmet needs and higher use of HIV medications in patients receiving HIV treatment.

Screening for cervical cancer in HIV-infected women receiving care in the United States.

OBJECTIVE: We examined the sociodemographic, clinical and provider factors associated with screening for cervical cancer among HIV-infected women. METHODS: We studied a national sample representing 43,490 women receiving treatment of HIV infection who completed first follow-up surveys of the HIV Cost and Service Utilization Study (HCSUS). All women were asked, "In the past 12 months, have you had a Pap test?" Women reporting an abnormal Pap test result were asked whether they had been told antibiotics could cure abnormal cells, and whether they were scheduled for another Pap test or for a colposcopy within 3 months. RESULTS: Of the population represented, 81% had had a Pap test in the past 12 months. Women who reported having a gynecologist and primary care physician at the same clinical site were almost twice as likely (odds ratio, 1.9; 95% confidence interval, 1.3-3.0) as other women to report Pap testing. Among women who reported abnormal Pap test results and were not told antibiotics could cure abnormal cells, 95% were scheduled for a repeat Pap test or colposcopy, but 15% of the women had not received their repeat Pap test or colposcopy. CONCLUSION: Although Pap test rates and appropriate referral for abnormal findings were high among HIV-tested women, many women with initially abnormal Pap test results did not actually receive follow-up Pap testing or colposcopy. Providing gynecologic care at the same site as primary HIV care would likely improve delivery of needed gynecologic care for women.

Use of contraceptive methods among homeless women for protection against unwanted pregnancies and sexually transmitted diseases: prior use and willingness to use in the future.

Lifetime contraceptive use as reported by a representative sample of 764 homeless women in Los Angeles was examined overall and for different age and ethnic subgroups and contrasted with expressed willingness to use specific methods. Over 80% of the women reported condom use. However, less than 5% had ever used female condoms, although 38% of the overall sample and 73% of the teenagers said they were willing to try them. Similar gaps between reported use and endorsement were found for other particular methods. Native Americans had relatively low use of virtually all contraceptive methods, and over 80% of African-Americans rejected implants. Our findings suggest that age-related factors and ethno-cultural perceptions may deter some homeless women from using contraception. In any case, gaps between realized use and willingness to use may represent missed opportunities to prevent the high rates of unintended pregnancies and sexually transmitted infections found among homeless women.

Just how integrated are integrated delivery systems? Results from a national survey.

This article examines three emergent processes in physician-hospital integrated delivery systems (IDSs). We find these processes are underdeveloped based on data gathered from a national sample of hospitals drawn from nine health care systems. These processes are also loosely coupled with the structures used to integrate physicians and hospitals, as well as with the environmental context in which they occur. Such loose coupling entails both advantages and disadvantages for IDSs.

A comparison of unmet needs for dental and medical care among persons with HIV infection receiving care in the United States.

OBJECTIVE: Oral health conditions associated with HIV disease are frequently more severe than those of the general population, making access to both dental and medical care important. Using the domains specified in the Behavioral Model of Health Services Use, this paper examines the correlates of unmet needs for dental and medical care in a nationally representative sample of patients with HIV. METHODS: This investigation is a cross-sectional study using baseline data from the HIV Cost and Services Utilization Study (HCSUS), the first nationally representative study of persons in care for HIV. Using probability-based techniques, 4,042 people were randomly selected in January 1996, and 2,864 (71%) completed a structured interview that included questions on unmet needs for dental and medical care. Regression analysis was used to identify variables associated with having unmet needs for dental care only, medical care only, and both medical and dental care. RESULTS: Of the estimated 230,900 people in treatment for HIV in the United States, approximately 58,000 had unmet medical or dental needs based on self-reported data. Unmet dental needs were more than twice as prevalent as unmet medical needs (32,900 vs 14,300), and 11,600 people were estimated to have both types of unmet needs. Multinomial logit regression showed that persons with low income had increased odds of reporting unmet needs for both dental and medical care. The uninsured and those insured by Medicaid without dental benefits had more than three times the odds of having unmet needs for both types of care than did the privately insured. CONCLUSIONS: To serve both the dental and medical needs of diverse populations affected by HIV disease, greater coordination of services is needed. In addition, state insurance programs for people with HIV should consider the feasibility of expanding their benefit structure to include dental care benefits.

Homeless women's gynecological symptoms and use of medical care.

Information is lacking on homeless women's gynecological symptoms and use of medical care for symptoms. This paper documents and explains gynecological symptoms and conditions and use of medical care in a probability sample of 974 reproductive-age (15-44) homeless women. Two-thirds of women reported symptoms during the previous year; 71 percent of those received medical care for their gynecological symptoms. Pregnancy, drug dependence, more episodes of homelessness, and general physical health symptoms were positively associated with a number of gynecological symptoms. Gynecological symptoms, younger age, better perceived health, and insurance coverage were positively associated with medical care; women reporting recent drug use and rape received less care. These findings support the importance of medical care and other treatment and support services for homeless women, including expanded care during pregnancy and substance abuse treatment. Health insurance coverage and an interruption in the cycle of homelessness also appear vital to women's health.

Prevalence and predictors of highly active antiretroviral therapy use in patients with HIV infection in the united states. HCSUS Consortium. HIV Cost and Services Utilization.

BACKGROUND: Highly active antiretroviral therapy (HAART) became standard for HIV in 1996. Studies at that time showed that most people infected with HIV had initiated HAART, but that members of minority groups and poor people had lower HAART use. It is not known whether high levels of HAART use have been sustained or whether socioeconomic and racial disparities have diminished over time. OBJECTIVES: To determine the proportion of patients who had received and were receiving HAART by January 1998, and to evaluate predictors of HAART receipt. DESIGN AND PARTICIPANTS: Prospective cohort study of a national probability sample of 2267 adults receiving HIV care who completed baseline, first follow-up, and second follow-up interviews from January 1996 to January 1998. MAIN OUTCOME VARIABLES: Proportion currently using HAART at second follow-up (August 1997 to January 1998), contrasted with the cumulative proportions using HAART at any time before January 1998 and before December 1996. ANALYSES: Bivariate and multiple logistic regression analysis of population characteristics predicting current use of HAART at the time of the second follow-up interview. RESULTS: The proportion of patients ever having received HAART increased from 37% in December 1996 to 71% by January 1998, but only 53% of people were receiving HAART at the time of the second follow-up interview. Differences between sociodemographic groups in ever using HAART narrowed after 1996. In bivariate analysis, several groups remained significantly less likely to be using HAART at the time of the second follow-up interview: blacks, male and female drug users, female heterosexuals, people with less education, those uninsured and insured by Medicaid, those in the Northeast, and those with CD4 counts of >/=500 cells/microl (all p <.05). Using multiple logistic regression analysis, low CD4 count (for CD4 <50 cells/microl: odds ratio [OR], 3.20; p <.001) remained a significant predictor of current HAART use at the time of the second follow-up interview, but lack of insurance (OR, 0.71; p <.05) predicted not receiving HAART. CONCLUSIONS: The proportion of persons under HIV care in the United States who had ever received HAART increased to over 70% of the affected population by January 1998 and the disparities in use between groups narrowed but did not disappear. However, nearly half of those eligible for HAART according to the U.S. Department of Health and Human Services guidelines were not actually receiving it nearly 2 years after these medications were first introduced. Strategies to promote the initiation and continuation of HAART are needed for those without contraindications and those who can tolerate it.

Delayed medical care after diagnosis in a US national probability sample of persons infected with human immunodeficiency virus.

OBJECTIVE: To identify health care and patient factors associated with delayed initial medical care for human immunodeficiency virus (HIV) infection. DESIGN: Survey of a national probability sample of persons with HIV in care. SETTING: Medical practices in the contiguous United States. PATIENTS: Cohort A (N = 1540) was diagnosed by February 1993 and was in care within 3 years; cohort B (N = 1960) was diagnosed by February 1995 and was in care within 1 year of diagnosis. MAIN OUTCOME MEASURE: More than 3- or 6-month delay. RESULTS: Delay of more than 3 months occurred for 29% of cohort A (median, 1 year) and 17% of cohort B. Having a usual source of care at diagnosis reduced delay, with adjusted odds ratios (ORs) of 0.61 (95% confidence interval [CI], 0.48-0.77) in cohort A and 0. 70 (95% CI, 0.50-0.99) in cohort B. Medicaid coverage at diagnosis showed lower adjusted ORs of delay compared with private insurance (cohort A: adjusted OR, 0.52; 95% CI, 0.30-0.92; cohort B: adjusted OR, 0.48; 95% CI, 0.27-0.85). Compared with whites, Latinos had 53% and 95% higher adjusted ORs of delay (P<.05) in cohorts A and B, respectively, and African Americans had a higher adjusted OR in cohort A (1.56; 95% CI, 1.19-2.04). The health care factors showed similar effects on delay of greater than 6 months. CONCLUSIONS: Medicaid insurance and a usual source of care were protective against delay after HIV diagnosis. After full adjustment, delay was still greater for Latinos and, to a lesser extent, African Americans compared with whites.

Care of vaginal symptoms among HIV-infected women.

OBJECTIVE: Gynecologic disease is common in HIV-infected women. We examine the sociodemographic, clinical, and provider factors associated with the care of women with vaginal symptoms. METHODS: Women enrolled in the HIV Cost and Services Utilization Study (HCSUS), a nationally representative probability sample of HIV-infected adults, were interviewed between January 1996 and April 1997. Women with vaginal symptoms who sought medical attention were asked, "Did your health care provider examine your vaginal area?" Women were also asked if they received medication for their symptoms. RESULTS: Among 154 women with vaginal symptoms, 127 sought care for their symptoms. Of those who sought care, 48% saw a gynecologist and 52% sought care from nongynecologists, most often their usual HIV care provider. Women who saw a gynecologist for their symptoms were more likely to have received a pelvic examination (92% versus 76%; p =.06) and vaginal fluid collection (98% versus 88%; p =.06) than those who saw their regular HIV provider. Fifteen percent of women received medication for their symptoms without having a pelvic examination; gynecologists were less likely to prescribe without an examination (8% versus 21%; p =.12). CONCLUSION: Gynecologists are more likely to provide adequate care of vaginal symptoms among HIV-infected women than nongynecologists who were HIV care providers. This specialty difference is consistent with quality of care studies for other medical conditions, but the potential gynecologic complications of inadequate evaluation and treatment warrants further investigation.

Prevalence and predictors of unmet need for supportive services among HIV-infected persons: impact of case management.

BACKGROUND: Previous research has indicated that the needs of persons infected with human immunodeficiency virus (HIV) for supportive services often go unmet. Although case management has been advocated as a method of decreasing unmet needs for supportive services, its effectiveness is poorly understood. OBJECTIVES: To assess the prevalence of need and unmet need for supportive services and the impact of case managers on unmet need among HIV-infected persons. RESEARCH DESIGN: National probability sample. PARTICIPANTS: A total of 2,832 HIV-infected adults receiving care. MEASURES: Need and unmet need for benefits advocacy, housing, home health, emotional counseling, and substance abuse treatment services. RESULTS: Sixty-seven percent of the sample had a need for at least one supportive service, and 26.6% had an unmet need for at least one service in the previous 6 months. Contingent unmet need (unmet need among persons who needed the service) was greatest for benefits advocacy (34.6%) and substance abuse treatment (27.6%). Fifty-seven percent of the sample had had contact with their case manager in the previous 6 months. In multiple logistic regression analysis, with adjustment for covariates, having a case manager was associated with decreased unmet need for home healthcare (OR =0.39; 95% CI = 0.25-0.60), emotional counseling (OR = 0.54; 95% CI = 0.38-0.78), and any unmet need (OR = 0.70; 95% CI = 0.54-0.91). An increased number of contacts with a case manager was significantly associated with lower unmet need for home health care, emotional counseling, and any unmet need. CONCLUSIONS: Need and unmet need for supportive services among HIV-infected persons is high. Case management programs appear to lower unmet need for supportive services.

Demonstrating successful aging using the International Collaborative Study for Oral Health Outcomes.

As the lifespan increases and people are faced with 15 to 20 years of "old age," we ask what one considers successful aging with respect to oral health. We propose a comprehensive combination of outcome variables, maintenance of teeth, manageable periodontal condition, positive perceived oral health, satisfaction with their access to and receipt of dental services, and minimal functional problems, that together comprise a definition of successful aging. The International Collaborative Study for Oral Health Outcomes provides a data set for exploring the oral health of a diverse sample of older adults in US and international sites using the modified Andersen Behavioral Model. The percent of adults who report no natural teeth ranged from 16 percent in San Antonio to 59 percent in New Zealand. Seventy percent or more of the adults from each site rated their oral health as good/fair or better except in Poland. The current cohort of older adults is faring better on some indicators than others; nevertheless, ethnic minorities and poorer countries still demonstrate inequities. Dentistry must attempt to educate individuals early in their lifespan that a combination of personal oral health practices and current dental techniques offers the potential for successful oral health throughout one's lifetime.

Use of dental care by HIV-infected medical patients.

Although increasing attention has been paid to the use of dental care by HIV patients, the existing studies do not use probability samples, and no accurate population estimates of use can be made from this work. The intent of the present study was to establish accurate population estimates of the use of dental services by patients under medical care. The study, part of the HIV Cost and Services Utilization Study (HCSUS), created a representative national probability sample, the first of its kind, of HIV-infected adults in medical care. Both bivariate and logistic regressions were conducted, with use of dental care in the preceding 6 months as the dependent variable and demographic, social, behavioral, and disease characteristics as independent variables. Forty-two percent of the sample had seen a dental health professional in the preceding 6 months. The bivariate logits for use of dental care show that African-Americans, those whose exposure to HIV was caused by hemophilia or blood transfusions, persons with less education, and those who were employed were less likely to use dental care (p < 0.05). Sixty-five percent of those with a usual source of care had used dental care in the preceding 6 months. Use was greatest among those obtaining dental care from an AIDS clinic (74%) and lowest among those without a usual source of dental care (12%). We conclude that, in spite of the high rate of oral disease in persons with HIV, many do not use dental care regularly, and that use varies by patient characteristics and availability of a regular source of dental care.

Predicting health services utilization among homeless adults: a prospective analysis.

This study expands on the Andersen-Newman health services utilization (HSU) model. In a community-based homeless sample (n = 363) baseline predisposing, enabling, and needs-based variables predicted hospitalization and ambulatory outpatient service utilization within 1 year after baseline. Standard predisposing and enabling variables were supplemented with latent constructs representing substance use, mental illness, poor housing status, social support, community support, and barriers to health care. Need is represented by baseline health status. Poor physical health, more barriers, drug use, African American ethnicity, less community support, and less education predicted hospitalization, the least desirable form of HSU. Poor health, female gender, a regular source of care, community support, drug use, and fewer alcohol problems predicted an office visit. Because outpatient visits for acute conditions provide an opportunity for generally neglected preventive services and health screenings, this study suggests convenient multiservice health-related programs for the homeless that include drug and alcohol treatment.

Ethnic and racial differences in long-term survival from hospitalization for HIV infection.

This prospective cohort study compares 200 hospitalized, HIV-infected patients (Hispanic, African American, and white) from May 1992 to October 1998 to assess mortality (versus survival) over 75 months of follow-up. The relative risk of six-year mortality for each ethnic group is compared using Cox proportional hazards models after controlling for sociodemographic and clinical characteristics, access to general medical care, and HIV-specific treatment. The median survival of Hispanics (15.5 months) was significantly (p < 0.05) shorter than that of whites (23.8); survival for African Americans (35.1) did not differ from whites. In multivariate analysis, the adjusted relative risk of six-year mortality for Hispanics compared with whites was 2.14 (95 percent confidence interval = 1.26-3.66). The poor outcomes of Hispanics was not explained by access to general care or by HIV-specific treatment.

Delays in seeking HIV care due to competing caregiver responsibilities.

OBJECTIVES: This study sought to describe the characteristics of HIV-infected persons who delay medical care for themselves because they are caring for others. METHODS: HIV-infected adults (n = 2864) enrolled in the HIV Cost and Services Utilization Study (1996-1997) were interviewed. RESULTS: The odds were 1.6 times greater for women than for men to put off care (95% confidence interval [CI] = 1.2, 2.2); persons without insurance and with CD4 cell counts above 500 were also significantly more likely to put off care. Having a child in the household was associated with putting off care (odds ratio [OR] = 1.8, 95% CI = 1.4, 2.3). CONCLUSIONS: Women or individuals with a child in the household should be offered services that might allow them to avoid delays in seeking their own medical care.

The Behavioral Model for Vulnerable Populations: application to medical care use and outcomes for homeless people.

OBJECTIVES: (1) To present the Behavioral Model for Vulnerable Populations, a major revision of a leading model of access to care that is particularly applicable to vulnerable populations; and (2) to test the model in a prospective study designed to define and determine predictors of the course of health services utilization and physical health outcomes within one vulnerable population: homeless adults. We paid particular attention to the effects of mental health, substance use, residential history, competing needs, and victimization. METHODS: A community-based probability sample of 363 homeless individuals was interviewed and examined for four study conditions (high blood pressure, functional vision impairment, skin/leg/foot problems, and tuberculosis skin test positivity). Persons with at least one study condition were followed longitudinally for up to eight months. PRINCIPAL FINDINGS: Homeless adults had high rates of functional vision impairment (37 percent), skin/leg/foot problems (36 percent), and TB skin test positivity (31 percent), but a rate of high blood pressure similar to that of the general population (14 percent). Utilization was high for high blood pressure (81 percent) and TB skin test positivity (78 percent), but lower for vision impairment (33 percent) and skin/leg/foot problems (44 percent). Health status for high blood pressure, vision impairment, and skin/leg/foot problems improved over time. In general, more severe homeless status, mental health problems, and substance abuse did not deter homeless individuals from obtaining care. Better health outcomes were predicted by a variety of variables, most notably having a community clinic or private physician as a regular source of care. Generally, use of currently available services did not affect health outcomes. CONCLUSIONS: Homeless persons are willing to obtain care if they believe it is important. Our findings suggest that case identification and referral for physical health care can be successfully accomplished among homeless persons and can occur concurrently with successful efforts to help them find permanent housing, alleviate their mental illness, and abstain from substance abuse.

Perceived effectiveness of teaching methods for heath services administration education.

This article brings to the forefront the challenges of establishing an empirical link between teaching methods and education outcomes in the classroom. In the health administration education field, precious little empirical data exist on the effectiveness of various teaching methods and approaches on achieving education outcomes. Results are reported from the 1998 National Survey of program directors of the AUPHA graduate programs on the perceived effectiveness of a wide range of teaching methods, using a Likert scale, ranging from very effective to not very effective. The authors elaborate on the highest- and lowest-ranked teaching methods, and propose a research agenda for measuring education outcomes in the classroom.
