Surgical repair of parastomal bulging: a retrospective register-based study on prospectively collected data. Colorectal Dis 2020; 22:1704-1713. [PMID: 32548884 DOI: 10.1111/codi.15197] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Accepted: 05/13/2020] [Indexed: 12/16/2022]
Abstract
AIM The aim of this work was to examine (1) the incidence of primary repair, (2) the incidence of recurrent repair and (3) the types of repair performed in patients with parastomal bulging. METHOD Prospectively collected data on parastomal bulging from the Danish Stoma Database were linked to surgical data on repair of parastomal bulging from the Danish National Patient Register. Survival statistics provided cumulative incidences and time until primary and recurrent repair. RESULTS In the study sample of 1016 patients with a permanent stoma and a parastomal bulge, 180 (18%) underwent surgical repair. The cumulative incidence of a primary repair was 9% [95% CI (8%; 11%)] within 1 year and 19% [95% CI (17%; 22%)] within 5 years after the occurrence of a parastomal bulge. We found a similar probability of undergoing primary repair in patients with ileostomy and colostomy. For recurrent repair, the 5-year cumulative incidence was 5% [95% CI (3%; 7%)]. In patients undergoing repair, the probability was 33% [95% CI (21%; 46%)] of having a recurrence requiring repair within 5 years. The main primary repair was open or laparoscopic repair with mesh (43%) followed by stoma revision (39%). Stoma revision and repair with mesh could precede or follow one another as primary and recurrent repair. Stoma reversal was performed in 17% of patients. CONCLUSION Five years after the occurrence of a parastomal bulge the estimated probability of undergoing a repair was 19%. Having undergone a primary repair, the probability of recurrent repair was high. Stoma reversal was more common than expected.

Incidence and risk factors for parastomal bulging in patients with ileostomy or colostomy: a register-based study using data from the Danish Stoma Database Capital Region. Colorectal Dis 2018; 20:331-340. [PMID: 28980388 DOI: 10.1111/codi.13907] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2017] [Accepted: 09/04/2017] [Indexed: 02/08/2023]
Abstract
AIM The aim was to investigate the incidence and risk factors for parastomal bulging, a clinically important complication, in patients with an ileostomy or colostomy. METHOD The Danish Stoma Database Capital Region prospectively collects data on patients with a stoma up to a year after surgery. Stoma care nurses clinically assessed the main outcome, parastomal bulging. We linked data from the Stoma Database to data from the Danish Anaesthesia Database. Cumulative incidence of parastomal bulging over the first year was calculated with death and stoma reversal as competing risks. Risk factors were investigated using an exploratory approach. RESULTS In a study population of 5019, the cumulative incidence (with competing risks) of parastomal bulging was 36.2% at 400 days after surgery. Age, colostomy, male gender, alcohol consumption and laparoscopy were associated with an increased risk of parastomal bulging. Compared with cancer, inflammatory bowel disease was associated with a lower risk of parastomal bulging, and diverticulitis was associated with a higher risk. Peristomal mesh and stomas placed through a separate incision were associated with a reduction in risk. There was neither increased nor decreased risk of parastomal bulging for body mass index, American Society of Anesthesiologists score, smoking status, emergency surgery and preoperative stoma site marking. CONCLUSION Parastomal bulging is a common complication affecting one in three patients within 1 year of surgery. Along with previous findings, there is now considerable evidence for age and colostomy as being risk factors for parastomal bulging.

Intra-operative Ultrasound as a Tool to Assess Free Borders of Primary Vascular Aortic Tumors During Resection. EJVES Short Rep 2016; 31:6-8. [PMID: 28856300 PMCID: PMC5573110 DOI: 10.1016/j.ejvssr.2016.03.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Revised: 02/18/2016] [Accepted: 03/06/2016] [Indexed: 12/03/2022] Open
Abstract
Introduction Primary vascular tumors are rare and, in general, have a poor prognosis. Complete resection is associated with a better prognosis. Radical resection depends on safe discrimination of tumor borders. Technical summary A 54 year old woman presented with abdominal pain. Imaging revealed a mass in the thoracic aorta, highly suspicious of angiosarcoma which was confirmed post-operatively by histological analysis. Open surgery was performed. Prior to clamping of the aorta, intra-operative ultrasound established clear delineation of the tumor borders. Conclusion Intra-operative ultrasound was, in this case, a safe and easy method to determine the tumor borders, providing a simple guide to in toto tumor removal.

Trends of barriers to eye care among adults with diagnosed diabetes in Germany, 1997-2012. Nutr Metab Cardiovasc Dis 2015; 25:906-915. [PMID: 26298427 DOI: 10.1016/j.numecd.2015.07.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2015] [Revised: 07/09/2015] [Accepted: 07/13/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS To study trends of barriers to receiving recommended eye care among subjects with diabetes aged 20-81 years in northeast Germany. METHODS AND RESULTS We analyzed population-based data from two repeated cross-sectional surveys conducted in 1997-2001 and 2008-2012 (Ns of 4308 and 4402). Andersen's Behavioral Model of Health Services Utilization was used to identify individual-level demographic, financial and health-related barriers to annual eye-care utilization in subjects with a self-reported physician's diabetes and to examine population trends in these barriers. The prevalence of diabetes increased from 6.5% to 11.4%. The prevalence of annual eye-care utilization among persons with diabetes decreased from 69.4% to 56.0% (adjusted relative risk = 0.77, p < 0.001). The decline of eye care utilization over the past decade in eye-care use was more pronounced in groups at risk for diabetes-related complications (i.e., lower socio-economic status, >5 years since diagnosis of diabetes, poor glycemic control, obesity, smoking, lack of physical activity, co-existing diseases). We identified relevant predictors of missed annual eye-care use among diabetics. CONCLUSION The increase of diabetes prevalence and downward trend of eye-care visits at the recommended level call for development, implementation and evaluation of continued efforts to improve access to eye specialists, particularly among those with poor diabetic control, co-existing diabetic complications, and comorbidities.

Abstract
The USA dental education programmes are facing challenges similar to those confronting countries around the globe, particularly amongst the industrialised nations. The purpose of this study was to evaluate the educational programmes of 15 USA dental schools to determine their impact on improving workforce diversity and oral health care access. The study investigates the predictors of public service plans of dental school seniors in Pipeline and non-Pipeline Program dental schools. We analysed baseline and post-intervention data collected in the American Dental Education Association (ADEA) Annual Survey of Dental School Seniors and a set of contextual variables. Public service plans (dependent variable) was predicted by four types of independent variables: intervention, contextual, community-based dental education (CBDE), and student characteristics. Findings from the study show that access to a state or federally sponsored loan repayment program was the most significant predictor of public service plans and that increasing educational debt was the most significant barrier. In the short-term we may be able to sustain the USA loan repayment programs to motivate senior dental students to provide public service to address the oral health care access crisis. However, in the long-term, a new workforce development initiative will be required to transform dental education and practice, modelled after the well-respected licensure programmes for Physician Assistants and/or Advanced Practice Registered Nurses, to expand oral health care access, particularly amongst vulnerable population subgroups, such as low-income children and families.

Abstract
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.

Abstract
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.

Program directors' recommendations for transforming health services management education. THE JOURNAL OF HEALTH ADMINISTRATION EDUCATION 2001; 18:153-73; discussion 174-9.

Abstract
A survey of graduate program directors shows that they recognize major change taking place in the health services industry and the need for programs to respond with curriculum revision. The revisions proposed tend to emphasize more practice involvement and human resources management skills rather than increased quantitative and financial competencies. Is this the right direction for programs to take? Will such revisions produce graduates better able to manage and lead in the emerging health care environment? We need more evidence-based research to answer these questions. In the meantime we have developed an environmental typology suggesting some rather clear distinctions among programs according to their settings. We know that the resulting categories of programs vary according to their national reputations and the kind of students that they serve. Do these different categories of programs prepare their different students well for the changing health care environment? Our current evidence, again, is sparse, indicating the need for further research.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
The objectives of this paper are three-fold. The first is to propose a conceptual and analytical framework for planning and evaluating health services management education programs. The framework was developed in response to the health care industry restructuring and the emerging questions and concerns regarding how to strategically redesign the educational programs for the twenty-first century. Additionally, it was used to develop a questionnaire for the 1998 National Survey of Program Directors. The second objective is to suggest variables for operationalizing the framework as the field considers initiatives such as, "Evidence-Based Health Administration Education" (AUPHA Education Outcomes Task Force 1999; Griffith 2000) and other more standardized, quantifiable approaches to assessing program quality. The third objective is to report selected results from the 1998 National Survey of Program Directors focusing on the major changes impacting the health services industry and the implications for management education and development. In the future, ACEHSA and other accrediting commissions will likely consider evidence-based evaluation criteria for assessing and improving education program quality. The framework presented in this paper can be used as a starting point for conceptualizing and developing valid and reliable measures.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVES To examine whether competing subsistence needs and other barriers are associated with poorer access to medical care among persons infected with human immunodeficiency virus (HIV), using self-reported data. DESIGN Survey of a nationally representative sample of 2,864 adults receiving HIV care. MAIN INDEPENDENT VARIABLES Going without care because of needing the money for food, clothing, or housing; postponing care because of not having transportation; not being able to get out of work; and being too sick. MAIN OUTCOME MEASURES Having fewer than three physician visits in the previous 6 months, visiting an emergency room without being hospitalized; never receiving antiretroviral agents, no prophylaxis for Pneumocystis carinii pneumonia in the previous 6 months for persons at risk, and low overall reported access on a six-item scale. RESULTS More than one third of persons (representing >83,000 persons nationally) went without or postponed care for one of the four reasons we studied. In multiple logistic regression analysis, having any one or more of the four competing needs independent variables was associated with significantly greater odds of visiting an emergency room without hospitalization, never receiving antiretroviral agents, and having low overall reported access. CONCLUSIONS Competing subsistence needs and other barriers are prevalent among persons receiving care for HIV in the United States, and they act as potent constraints to the receipt of needed medical care. For persons infected with HIV to benefit more fully from recent advances in medical therapy, policy makers may need to address nonmedical needs such as food, clothing, and housing as well as transportation, home care, and employment support.

Abstract
Although AIDS prevention campaigns need to target population segments that are at highest risk to be effective, little is known about how various sources of AIDS information vary by race, education, and age. To determine the most common communication channels for AIDS information reported by Blacks and Whites, the authors interviewed 1,769 adults in Baltimore, Maryland, to obtain data on nine common sources of information about AIDS and analyzed their reports by race, age, and education. Television and newspapers were the most common sources but varied little across groups. National and local public health agencies, as well as medical doctors and dentists, were more commonly reported by Blacks than by Whites. Religious organizations were much more commonly reported by Blacks than by Whites. Public health organizations working collaboratively with religious organizations and health care providers might be more effective in developing AIDS prevention strategies than has been considered previously.

Abstract
The growth of physician-organization arrangements (e.g., PHOs, MSOs) by physician specialty groups and delivery organizations is widely acknowledged. Yet, little is known about these new organizational forms. This paper presents a descriptive analysis of physician-organization arrangements (POAs) using survey data obtained from 79 organizations. The analysis examines the extent to which healthcare delivery organizations are engaged in the development of POAs, the number of physicians involved in POAs, and the decision-making control and strategies associated with POAs. These attributes are examined for the sample as a whole and relative to the institutional and market conditions facing study participants. Results are discussed in terms of their implications for health services managers.

Abstract
Data collected from the International Collaborative Study of Oral Health Outcomes USA (ICS-II) research locations were used to evaluate the relationship between having a usual source of dental care (USDC) and access to dental services. The robustness of the USDC effect after reducing simultaneity bias was tested in the population-based samples using sensitivity analysis. Logistic regression results provided evidence that USDC was the strongest and most consistent predictor of a dental visit in the past 12 months regardless of geographic location, dental care delivery system, or cultural diversity of the population. Even removing cases that had a USDC for less than 1 or 2 years, the effect remained. From a policy perspective, USDC remains critical to understanding and explaining dental are utilization patterns. The findings suggest the need for designing interventions to increase the availability of a regular provider among vulnerable populations.

Abstract
Underscoring the importance of physician-organization alignment as a necessary condition for building and sustaining integrated healthcare systems, this article provides information regarding the nature of such alignment, the key influential factors, and the processes employed to make alignment a reality. Structural and strategic factors address the influence of environmental, market, and organizational characteristics on alignment. The strategic intent of organizations and physicians, and physician perspectives on the effects of integration, are explored. Key processes examined include building trust, placing physicians in management and governance, and developing physician leadership. Continuing issues and challenges are considered, and a set of principles to help guide the journey of physicians and organizations toward successful alignment is suggested.

Abstract
Lack of timely HIV testing leads to missed prevention opportunities and poor prevention counselling may be related to further disease spread. We examined the association of self-reported access to medical care with receiving HIV testing and preventive counselling services among a sample of patients with HIV disease prior to hospitalization. We conducted a cross-sectional interview of 217 Los Angeles patients hospitalized with HIV-related illness between 1992 and 1993 and abstracted clinical data from the medical record. Eighty-four per cent of patients received HIV testing prior to hospitalization, but only 33% received preventive counselling services. Only 48% of all patients rated outpatient medical care as somewhat or very easy to obtain. Controlling for severity of illness, better access to outpatient medical care (OR = 1.48; 95% CI = 1.02-2.15), having a regular source of care (OR = 3.40; 95% CI = 1.29-8.97) and non-homosexual mode of HIV transmission (OR = 0.31; 0.12-0.83) were associated with receiving HIV testing services prior to hospitalization. Having a regular source of care (OR = 3.55; 95% CI = 1.37-9.22), being VA (Veterans' Administration) insured (OR = 6.16; 1.46-26.05), older age (OR = 0.95; 95% CI = 0.90-0.99) and having a CD4 count between 101-200 (OR = 0.19; 95% CI = 0.06-0.63) were associated with receiving HIV counselling. Limited self-reported access to medical care is associated with fewer patients receiving HIV testing and counselling. Improving timeliness of HIV testing may require removing the barriers to medical care.

Abstract
We examine the use of nursing homes, formal personal care, informal Activities of Daily Living (ADL) assistance, and no care to identify racial differences in their use. Using the 1987 National Medical Expenditure Survey of both nursing homes and the community, multinominal logistic regressions controlled for predisposing, enabling, and need variables as well as other types of service use. Additional state-level variables make few changes in race/ethnicity parameters, indicating that race/ethnicity are not simply proxies for state-level variables. Older African Americans are less likely to use nursing homes than similar whites, with the lower institutionalization replaced by a higher use of paid home care, informal-only care, and no care. This suggests that formal in-home community care is not fully compensating for the racial differences in nursing home use. Persistent effects of race/ethnicity could be the result of culture, class, and/or discrimination that may impair equitable access to services.

Abstract
OBJECTIVES The authors explore the determinants of having a regular source of care in a community-based probability sample of homeless adults in Los Angeles. Results from this study should be more representative than those from previous studies of the homeless that are clinic- or shelter-based. In addition to those factors found to be barriers to regular sources of care in the general population, we hypothesized that psychosocial characteristics of the homeless and the homeless lifestyle would negatively impact their likelihood of having a regular source of care. METHODS The authors conducted a multiple logistic regression to predict regular source of care among the homeless, using an adaptation of the Behavioral Model of health services utilization as an analytic framework. RESULTS Fifty-seven percent of the sample reported that they had a regular source of care. Of those with a source of care, 30% reported a hospital outpatient department; 25% reported a community or homeless clinic; 23% reported a hospital emergency room; 14% reported a government clinic; and 9% reported a private physician's office as their source of care. Some factors found to be barriers to having a regular source of care in the general population (male, Hispanic, young age) also were barriers among homeless adults. Additional barriers in this sample included homelessness-related characteristics such as competing needs, long-term homelessness, and social isolation. Chronic mental illness and chronic substance dependence were not related to having a source of care among the homeless. Characteristics that increased the likelihood of having a regular source of care in the general population (poor health status, Medicaid) were not related to having a regular source of care among the homeless. CONCLUSIONS In a context of limited resources, the distribution of regular source of care among the homeless appears to be highly inequitable. Although some of the characteristics identifying those with a regular source of care suggest differential patterns of behavior across subgroups, others suggest differential advantage in access to care and a lack of fit between the needs of the homeless and the organization of health services.

Abstract
Using data from population-based samples of adults participating in the ICS-II USA study, and using principal components analysis, we constructed oral health belief measures corresponding to the Health Belief Model (HBM) dimensions. Tests of validity and reliability were performed. Scales measuring perceived benefit of preventive practices and seriousness of oral disease had the highest validity and reliability. We used multiple regression analysis to examine sociodemographic predictors of perceived benefits of preventive practices. Race-ethnicity and age cohort were significant predictors among Baltimore and San Antonio adults. White adults and middle-aged persons in both research locations were more likely to believe in the benefit of preventive practices. Female gender, higher educational attainment, and better self-rated health were significant indicators of more positive oral health beliefs in every research location. Results also characterize persons who place lower value on preventive practices (i.e., males, less-educated persons, and those reporting poorer self-rated health). The design of effective dental public health messages and outreach efforts requires an analysis of the individual's health orientation and the factors influencing oral health beliefs. Oral health education interventions designed to improve health beliefs should contain an evaluation component for assessing the impact of education on health practices and oral health status.

Abstract
In this study, socio-behavioral determinants of oral hygiene practices were examined across several dentate ethnic and age groups. Oral hygiene scale scores were constructed from toothbrushing and dental floss frequencies self-reported by population-based samples of middle-aged (35-44 years) and older (65-74 years) dentate adults representing Baltimore African-American and White, San Antonio Hispanic and non-Hispanic White, and Navajo and Lakota Native American persons participating in the WHO International Collaborative Study of Oral Health Outcomes (ICS-II) survey. Female gender, education, certain oral health beliefs, household income, and the presence of a usual source of care were revealed with multivariate analysis to show a significant positive relationship with higher oral hygiene scale scores (indicating better personal oral hygiene practices). Other socio-behavioral variables exhibited a more varied, ethnic-specific pattern of association with oral hygiene scale scores.

Abstract
Dental services utilization in the past 12 months was compared across population-based samples of African-American, Navajo, Lakota, Hispanic, and White adults participating in the WHO International Collaborative Study of Oral Health Outcomes (ICS-II) at USA research locations. Bivariate results revealed that ethnic minority groups in both age cohorts reported significantly fewer dental visits in the past 12 months compared with White adults. When dentate status was controlled for, age cohort differences were not significant in Baltimore (African-American and White) and San Antonio (Hispanic and White) research locations. In contrast, older Native Americans (65-74 years) reported visiting the dentist significantly less often compared with their middle-aged (35-44 years) counterparts. Multivariate results indicated that generalizable variables were associated with dental contact in every ICS-II USA ethnic group (i.e., dentate, usual source of dental care, oral pain). Among the diverse ethnic groups, other determinants presented a varied pattern of risk factors for underutilizing dental care. Information on ethnic-specific risk factors can be used to design culturally appropriate and acceptable oral health promotion programs. Generalizable risk factors across ethnic groups inform oral health policy-makers about changing national priorities for promoting oral health.

Abstract
An expanded version of Andersen's Behavioral Model of Health Services Utilization is used as the theoretical and analytical framework for the International Collaborative Study of Oral Health Outcomes (ICS-II). The conceptual framework for understanding determinants of oral health is based on a "systems" perspective. The framework posits that characteristics of the external environment, the dental care delivery system, and the personal characteristics of the population influence oral health behaviors. The expanded behavioral model conceptualizes health behaviors (oral hygiene practices and dental services utilization) as intermediate dependent variables, which in turn influence oral health outcomes (evaluated, perceived, patient satisfaction). The framework is presented with an increased focus on the effects of race-ethnicity and age cohort, the major exogenous variables used in this study for systematic assessment of the differences in the multitude of factors influencing oral health. The framework can be applied by policy analysis and health services managers to help describe, predict, and explain population-based health behaviors and health outcomes.

Abstract
The conceptual model used in the ICS-II USA Ethnicity and Aging project helps to identify who among the elderly should be targeted for oral health promotion initiatives and the kinds of initiatives most likely to promote positive oral health outcomes. Outcomes have been measured in this study as perceived by the individual and as clinically assessed by the oral epidemiologists. For policy purposes, achieving both types of outcomes is important. A typology of oral health promotion priorities is used to rank the diverse racial-ethnic groups. In the analysis, groups with both low perceived and low evaluated oral health status receive highest priority. By these criteria, the older Native American populations have the highest priority, followed, in order, by Hispanics, African-Americans, and non-Hispanic Whites. Policy implications of the empirical analyses presented in earlier articles are discussed by use of the conceptual model and the typology of oral health promotion priorities. Having a usual source of care and/or regular dental visits appears to be a promising avenue for the promotion of better-perceived oral health status among most older ethnic groups. Improved oral hygiene practices, as represented by both regular toothbrushing and dental floss use, promote better clinically evaluated oral health status among many older ethnic groups.

Abstract
The purpose of the WHO-sponsored International Collaborative Study of Oral Health Outcomes (ICS-II) was to provide policy-markers and researchers with detailed, reliable, and valid data on the oral health situation in their countries or regions, together with comparative data from other dental care delivery systems. ICS-II used a cross-sectional design with no explicit control groups or experimental interventions. A standardized methodology was developed and tested for collecting and analyzing epidemiological, sociocultural, economic, and delivery system data. Respondent information was obtained by household interviews, and clinical examinations were conducted by calibrated oral epidemiologists. Discussed are the sampling design characteristics for the USA research locations, response rates, samples size for interview and oral examination data, weighting procedures, and statistical methods. SUDAAN was used to adjust variance calculations, since complex sampling designs were used.

Abstract
OBJECTIVES The role of competing priorities as a barrier to the utilization of physical health services was assessed in a subset (n = 363) of a probability sample of homeless adults in Los Angeles. METHODS Unadjusted odds of four measures of health services utilization were calculated for those with frequent difficulty in meeting their subsistence needs. These odds were then adjusted for a range of characteristics assumed to affect the utilization of health services among the homeless. RESULTS Before and after adjustment, those with frequent subsistence difficulty were less likely to have a regular source of care (odds ratio [OR] = 0.30, 95% confidence interval [CI] = 0.16, 0.53) and more likely to have gone without needed medical care (OR = 1.77, 95% CI = 1.04, 3.00). Subsistence difficulty had no impact on the likelihood of having an outpatient visit or having been hospitalized. Conclusions remained the same after adjustment. CONCLUSIONS Frequent subsistence difficulty appears to be an important nonfinancial barrier to the utilization of health services perceived as discretionary among homeless adults.

Abstract
OBJECTIVE To document the prevalence of tuberculosis (TB) skin test positivity among homeless adults in Los Angeles and determine whether certain characteristics of homelessness were risk factors for TB. DESIGN Cross-sectional study. SETTING Shelters, soup lines, and outdoor locations in the Skid Row and Westside areas of Los Angeles. PARTICIPANTS A representative sample of 260 homeless adults. MEASUREMENTS AND MAIN RESULTS Tuberculosis tine test reactivity was measured. The overall prevalence of TB skin test positivity was 32%:40% in the inner-city Skid Row area and 14% in the suburban Westside area. Using multiple logistic regression, TB skin test positivity was found to be associated with living in crowded or potentially crowded shelter conditions, long-term homelessness, geographic area, history of a psychiatric hospitalization, and age. CONCLUSIONS Homeless adults living in congested inner-city areas are at high risk of both latent and active TB. Endemic risk factors and limited access to medical care support the need for aggressive treatment of active TB cases and innovative programs to ensure completion of prophylactic regimens by homeless individuals with latent infection.

Abstract
Long-term care policy has evolved with little attention to racial differences in the need for and use of services. Using 1987 National Medical Expenditure Survey data on nursing home care, formal in-home personal care, and informal-only help, a model was created to show how different races would use each type of care if: (1) a universal home-care benefit was established, (2) existing Medicaid home-care benefits were ended, or (3) the income level for Medicaid eligibility was substantially reduced. Expanded community care benefits would primarily serve severely disabled older whites. Reductions in long-term care benefits or eligibility would disproportionately impede access to long-term care for severely disabled older African-Americans. These differences indicate that race must be taken into account in long-term care policy initiatives.

Access to community-based medical services and number of hospitalizations among patients with HIV disease: are they related? JOURNAL OF ACQUIRED IMMUNE DEFICIENCY SYNDROMES AND HUMAN RETROVIROLOGY : OFFICIAL PUBLICATION OF THE INTERNATIONAL RETROVIROLOGY ASSOCIATION 1996; 13:327-35.

Abstract
To assess whether better access to community-based outpatient medical services was associated with fewer HIV-related hospitalizations, we studied 217 patients hospitalized at seven southern California hospitals. During hospital admission, patients completed an interview that included one item about the reported difficulty or ease of access to community-based medical services prior to their first hospitalization for HIV-related illness. After discharge, medical records were abstracted for data on prior hospitalizations. CD4 counts, and illness severity. About one-half of patients reported that medical services were readily accessible. Medical records revealed that since the time of HIV infection 49% had two or more total hospitalizations (mean = 2. SD = 2). In multiple logistic regression analysis, better reported access to services was significantly associated with not having been hospitalized (vs. having been hospitalized) over the same time period (OR = 0.73, 95% CI = 0.55-0.97), controlling for CD4 count, illness severity, duration of diagnosed HIV infection, having a regular source of care, type of hospital care, insurance coverage, and other patient characteristics. Improving access to community-based medical services for ambulatory HIV-infected patients may help to avert costly hospital care. Prospective studies are needed to assess whether a causal relationship between greater community-based access and reduced hospitalizations exists and, if so, whether community-based services may be cost-effective substitutes for hospital HIV care.

Abstract
Racial-ethnic group differences are assessed using a standardized set of oral health indicators, as well as various predisposing, enabling and need characteristics collected in the International Collaborative Study of Oral Health Outcomes (ICS-II) USA research locations. The unique data set contains comparable data on African-American, Native American, Hispanic, primarily Mexican-American, and White adults. Age group differences in oral health indicators are also compared in two adult age cohorts (35-44 and 65-74 years). Since data were collected from geographically diverse regions of the United States, differences in oral health indicators are considered within the context of different dental care delivery systems and external environments. Results indicate that the gap in oral health between Whites and ethnic minority groups is pervasive across research locations and age cohorts. Variation in regional dental care delivery systems and the varying effects of race-ethnicity and age cohort suggest that alternative health promotion strategies will be needed for improving oral health in diverse populations.

Abstract
Integrated health care organizations depend fundamentally on bringing organizations and physicians into closer alignment. Little empirical research has been conducted on the organizational mechanisms by which such alignment is attempted. This study employed primary data from 79 hospitals and health care systems to identify current approaches to aligning the strategic and economic interests of organizations and physicians. An empirical classification of both unbundled and structured physician-organization arrangements (POAs) resulted in 5 distinct strategic configurations. These configurations were differentiated by key contextual factors that shape patterns of development and operation of POAs. Particularly salient among these were managed care penetration, organization size, locus of control, and organization strategy. Results of the taxonomic analysis underscore the facts that most delivery organizations employ multifaceted rather than single approaches to physician integration and that these approaches are endemic to particular environmental and organizations conditions.

Abstract
Clinical biomedical research, the traditional research orientation of quality of life (QOL) researchers, is chiefly concerned with disease processes and assessing the impact of therapeutic interventions on improving health status and QOL outcomes. This paper suggests, however, that the biomedical paradigm limits utility of QOL research findings in terms of its ability to shape health policy and improve health-related QOL in populations at risk. This paper proposes that health services research (HSR) and other health research paradigms can be used to assess QOL from multiple perspectives. HSR and QOL research can be mutually beneficial. The models for understanding health services utilized in HSR may assist in defining major determinants of QOL and the interaction of QOL with its environment. Conversely, QOL measures may be used to establish the relevance of HSR to people's well-being. The paper first defines the domain of HSR and the domain of quality of life. In order to understand their relationship, we consider what a model or paradigm for each might be, and how they would overlap. Finally, a merging of conceptual frameworks is proposed, linking QOL research to HSR and other health research. Ultimately, expanding the QOL paradigm beyond the biomedical model will promote two objectives. First, it will permit research findings to contribute more fully to shaping national health policy by considering the broader community and the delivery system factors which influence QOL. Second, researchers will be more aware of a broader range of factors affecting patients and will incorporate this in their research.

Abstract
Findings from two surveys of all physicians in Pima County, Arizona, in 1985 and 1990 to determine the trajectory of hospital/physician relationships suggest that conflicts have increased in almost all areas. Physicians report the greatest number of and increase in conflicts in traditional problem areas such as the quality of nursing and response to equipment requests. They report a smaller increase in conflicts relating to the new competitive marketplace, including hospital efforts to influence medical practice. Both types of problems are most prevalent among younger physicians. The new marketplace thus appears to exacerbate traditional hospital/physician conflicts more than it generates new areas of contention.

Abstract
The National Study of Internal Medicine Manpower (NaSIMM) reports on the results of its 1989-1990 census of residency programs. The results are integrated into an organizational model identifying inputs, process, outputs, and environment of medical training programs. The number of residents entering internal medicine continues to grow at a relatively rapid pace. This growth is largely accounted for by foreign citizens who are graduates of foreign medical schools (AFMGs). Residents are spending an increasing proportion of their time in ambulatory care settings, but, thus far, this ambulatory care training has occurred primarily in hospital clinics and emergency rooms. The proportion of a program's residents entering general internal medicine was found in a multiple regression analysis to be negatively associated with the number of subspecialty programs located in the training hospital, the percent of AFMG residents in the program, and the presence of a preliminary track in the program.
