Does fear of immigration authorities deter tuberculosis patients from seeking care?

Physician groups are concerned that legislation requiring physicians to report illegal immigrants to immigration authorities will delay curative care. In particular, patients with tuberculosis may delay seeking care for infectious symptoms and spread the disease. We surveyed 313 consecutive patients with active tuberculosis from 95 different facilities to examine the relationship of immigration-related variables, symptoms, and delay in seeking care. Most patients (71%) sought care for symptoms rather than as a result of the efforts of public health personnel to screen high-risk groups or to trace contacts of infectious persons. At least 20% of respondents lacked legal documents allowing them to reside in the United States. Few (6%) feared that going to a physician might lead to trouble with immigration authorities. Those who did were almost 4 times as likely to delay seeking care for more than 2 months, a period of time likely to result in disease transmission. Patients potentially exposed an average of 10 domestic and workplace contacts during the course of the delay. Any legislation that increases undocumented immigrants' fear that health care professionals will report them to immigration authorities may exacerbate the current tuberculosis epidemic.

Evaluation of two AIDS education programs for impoverished Latina women.

This paper evaluates and contrasts the effectiveness of two culturally sensitive AIDS education programs developed by the UCLA AIDS Nursing Network and delivered to 213 impoverished Latina homeless or drug-addicted women in Los Angeles. The Comprehensive Health Seeking and Coping Paradigm guided the program, which was implemented by specially trained Latina nurses and outreach workers. A quasi-experimental design was employed where women were randomized by site into Specialized (N = 82) and Traditional (N = 131) programs. Repeated measures ANOVAS and log-linear models were used to evaluate improvement over a two-week period for women in both groups and to identify interactions with program type. Two-week posttest analyses were also conducted to assess program effectiveness, controlling for baseline values of the measure in question, nonequivalency between groups at baseline, and selected demographic characteristics, including acculturation. Results indicated that women in both AIDS education programs improved significantly in cognitive, behavioral, and psychologic outcomes.

Outcomes of specialized and traditional AIDS counseling programs for impoverished women of color.

The efficacy and differential effects of specialized (S) and traditional (T) AIDS education programs on cognitive, behavioral, and psychological outcomes were investigated. The sample consisted of 858 impoverished African-American and Latina women (S = 448, T = 410). At baseline, women in the traditional group reported significantly higher distress, greater knowledge of AIDS, and less problem-focused coping. Significant improvements over the 2-week intervention interval were found for participants of both AIDS education programs for appraisal of threat, concerns, knowledge, and attitudes about AIDS, emotion-focused coping, number of sexual partners, IV and non-IV drug use, depression, and distress. However, multivariate analysis indicated that the traditional group had slightly better posttest scores on concerns, emotion-focused coping, knowledge of AIDS, and number of partners than the specialized group. The specialized group reported greater use of problem-focused coping. These differences do not detract from the substantial improvement found for both groups, but they do reinforce the conclusion that the specialized program was not more effective than its standard counterpart.

AIDS-related knowledge, perceptions, and behaviors among impoverished minority women.

OBJECTIVES: The aims of this study were to (1) describe AIDS-related knowledge, perceptions, and risky behaviors of impoverished African-American and high- and low-acculturated Latina women; (2) delineate relationships involving high-risk behaviors; and (3) determine whether risky behaviors differ by race and levels of acculturation. METHODS: Survey instruments were administered to 1173 impoverished women of color residing in homeless shelters and drug recovery programs. RESULTS: Differences based on ethnicity and level of acculturation were found in AIDS-related knowledge, perceived risk of acquiring AIDS, and risky behaviors. Low-acculturated Latinas reported low perceived risk and were least likely to engage in illegal drug use and sexual activity with multiple partners. Intravenous drug use was most prevalent among high-acculturated Latinas, whereas nonintravenous drug use and high-risk sexual activity was most prevalent among African-American women. CONCLUSIONS: The data indicate the need for culturally sensitive AIDS prevention programs for women that deal with general issues of drug use and unprotected sex, and that include separate sessions for women of different ethnic backgrounds and acculturation levels to address specialized areas of concern.

Clinical factors associated with better quality of life in a seriously mentally ill population.

Improving the quality of life of persons with chronic mental illness is becoming an important treatment goal. In this study, 101 former acute care psychiatric inpatients with serious mental illness who were living in Mississippi communities were interviewed using portions of Lehman's Quality of Life Interview. A particular focus was whether clinical characteristics, such as medication compliance and social skills, that could be changed by interventions were associated with patients' ratings of their quality of life. Self-reports of better quality of life were associated with fewer depressive symptoms, fewer medication side effects, and better family interactions. Results indicate that clinical interventions to improve quality of life in this population should include family psychoeducational programs and better detection, evaluation, and treatment of both depressive symptoms and side effects of medication.

How satisfying is the practice of internal medicine? A national survey.

OBJECTIVE: To survey members of the American College of Physicians about their level of satisfaction and sources of dissatisfaction with practice, the extent to which their satisfaction is reflected in their counseling of students about careers in internal medicine, the prevalence of their concerns about patients' access to care, and their attitudes toward changes in the health care system. DESIGN: A questionnaire survey of a random sample of members of the College. PARTICIPANTS: Members (2254) of the College were surveyed; 1446 (64%) responded and 1290 (57%) of the responses were usable. MEASUREMENTS AND MAIN RESULTS: More than 80% of respondents were satisfied with their relationships with patients, professional challenges, and opportunities to interact with colleagues. Only about half were satisfied with their potential income, and most were dissatisfied with their autonomy or loss of control over clinical decision making. Major sources of concern were administrative burdens, the threat of malpractice litigation, loss of income, and loss of clinical autonomy. Forty percent of internists say that they discourage students from careers in internal medicine, and only 39% would once again pursue such a career. "Pain in the practice" seems generalized among internists: logistic regression analysis failed to show any specific groups who were most dissatisfied or concerned. With regard to access, 18% of internists had many patients without health care insurance; 69% had some patients without coverage; and the majority (61%) had some patients who lost their insurance because of changing jobs or location. Assuring universal access to care received the highest priority rating of a set of criteria for health care reform. CONCLUSIONS: There is growing dissatisfaction with the practice of internal medicine, primarily related to concerns over loss of clinical autonomy, the increase in administrative burdens, the potential loss of income, and the threat of malpractice litigation. Although physicians are concerned about patients' access to care, proposals to improve access should be examined for their effects on the major sources of physicians' dissatisfaction with practice.

The counseling practices of internists.

OBJECTIVES: To determine the counseling practices of a group of internists in the areas of smoking, exercise, and alcohol and seat belt use, and to determine the associations among physicians' personal health habits and their counseling practices. DESIGN: A random stratified sample of members and fellows of the American College of Physicians in 21 regions selected to represent all areas of the United States. Because of the relatively small proportion of women in this group, they were oversampled. SETTING: Physicians' practices. PARTICIPANTS: One thousand three hundred and forty-nine internists (members or fellows of the College) returned questionnaires, for a response rate of 75%; 52% defined themselves as general internists. INTERVENTIONS: A questionnaire was used to obtain information on internists' use of cigarettes, alcohol, and seat belts and their level of physical activity. Data were obtained on the indications used for counseling and the aggressiveness of counseling about each of these four habits. MEASUREMENTS AND MAIN RESULTS: Bivariate and logistic regression analyses were used to compare the tendencies of internist subgroups both in using various indications for counseling and in the thoroughness of counseling. Generalists were more likely than specialists to counsel at least once all patients who were at risk and to be more aggressive in counseling. Ninety percent of respondents counseled all of their patients who smoked, but 64.5% never discussed the use of seat belts. Only 3.8% of these internists currently smoked cigarettes, 11.3% drank alcohol daily, 38.7% were extremely or quite active, and 87.3% used seat belts all or most of the time. Among men internists, for every habit except alcohol use, personal health practices were substantially associated with counseling patients; for example, nonsmoking internists were more likely to counsel smokers, and very physically active internists were more likely to counsel about exercise. Among women internists, being very physically active was associated with counseling more patients about exercise and alcohol use. CONCLUSIONS: The low level of self-reported counseling among these internists suggests that further emphasis on training in these skills is needed. The association between personal and professional practices suggests that medical schools and housestaff training programs should support health promotion activities for future internists.

Predictors of mortality in older patients following medical intensive care: the importance of functional status.

OBJECTIVE: We examined predictors of hospital and 6-month mortality in older Medical Intensive Care Unit (MICU) patients with particular attention to age and functional status. Age is generally thought to be strongly associated with intensive care outcomes, but this relationship may be confounded by age-related changes. These age-related changes may be approximated by changes in functional status (FS). DESIGN: We conducted a retrospective chart review and collected severity of illness data using the Acute Physiology Score (APS), pre-hospitalization FS dichotomized as limited or not limited, and hospital mortality. County death records were reviewed for 6-month mortality. SETTING: Three community hospital MICUs. PATIENTS: Four-hundred MICU patients aged 50 and older admitted during the study period. RESULTS: Limited FS was found in 42% of the 227 patients who had FS data in the chart. Mortality was significantly associated with APS, age, FS, immunocompromise state, comorbidity, and nursing home residence. In logistic regression analyses, while controlling for important variables, APS (P less than 0.001) and age greater than or equal to 75 with limited FS (P less than 0.05) were associated with hospital mortality. Six-month mortality predictors were APS (P less than 0.001), hospital (P less than 0.05), immunocompromised state (P less than 0.05) and age greater than or equal to 75 with limited FS (P less than 0.05). CONCLUSIONS: We found that among patients without functional limitations, the oldest group was no more likely to die than the youngest group. Age and functional status had a significant interaction: patients older than 75 years with functional limitations were almost six times more likely to die in hospital compared to the reference group of patients between 50-64 years old without functional limitations. We conclude that functional status is an important predictor of outcome in older MICU patients.

Patient satisfaction on AIDS and oncology special care units and integrated units: a pilot study.

The authors assessed patients' satisfaction with their nursing care in seven hospitals. Five of the hospitals utilized the special care unit (SCU) method of delivering care to AIDS or oncology patients; three had SCUs for AIDS patients. All seven of the hospitals had integrated units (IUs) where general medical, oncology, and/or AIDS patients were received in various proportions. Satisfaction with nursing care was measured with the Risser Patient Satisfaction Instrument. Patient satisfaction with nursing care was shown to be a function of delivery method; AIDS and oncology patients on SCUs expressed greater satisfaction with their care than medical, oncology, or AIDS patients on IUs (p less than .001). Patient satisfaction with nursing care was greater among whites than nonwhites. Also, some major sociodemographic and case mix variables, such as age, employment status, and diagnosis, were not associated with patient satisfaction directly; in other instances, the associations initially seen did not hold when delivery method (SCU vs. IU) and race were controlled for in a linear regression analysis.

Quality and cost of AIDS nursing care as a function of inpatient delivery systems.

Decisions to hospitalize persons with AIDS (PWAs) and the subsequent nursing process and outcomes associated with this hospitalization are of major concern to nurse administrators. Although decisions to hospitalize may be out of their control, events occurring during hospitalization that affect the quality of nursing care received are clearly the nurse administrator's responsibility. This report addresses a major issue concerning the care of PWAs: the decision to establish a dedicated AIDS unit. The effect upon both quality care and nursing care costs is discussed.

The limitations of generic AIDS educational programs for the health professions.

Three major trends are driving the widespread need for continuing education in AIDS. First, with the spread of AIDS, increasing numbers of health care professionals are becoming involved in the care and treatment of AIDS, ARC and HIV positive individuals. Second, as the disease spreads beyond current AIDS epicenters, more persons with minimal information are required to have a baseline working knowledge of AIDS. Finally, the reluctance of many health care professionals to care for HIV-positive individuals, along with already existing staff shortages, limits access to care and makes the provision of responsive educational programs even more important. Generic programs to educate health professionals frequently lack sufficient specificity and sensitivity to address the needs of health professionals with varying levels of knowledge and role responsibility. This paper briefly summarizes the literature on the similarities and differences in knowledge and attitudes across and within professional groups. In addition, it presents specific research designed to provide initial direction for considering the circumstances under which health professionals, particularly nurses and physicians, may or may not profit from generic programs aimed at mixed levels and types of health care provider.

The stresses of hospitalization among AIDS patients on integrated and special care units.

This study examined the stresses of hospitalization in AIDS patients and assessed the extent to which two different inpatient delivery systems differed with respect to perceived stresses in these patients. Patients from four AIDS dedicated special care units (SCU's) and five AIDS integrated units (IU's) in eight acute care hospitals were surveyed using a modified version of the Volicer Hospital Stress Rating Scale. Stresses related to loss of independence, separation from loved ones and problems with medications were experienced equally by both groups of patients. However, SCU patients had lower total hospital stress scores than IU patients in terms of the number of stresses experienced (p = 0.008) and how bothersome these stresses were perceived to be (p = 0.02). Additionally, patients on IU's more frequently experienced and were bothered by factors associated with ambiguity about their care and condition and feelings of abandonment and impersonal or discriminatory treatment.

Physicians' perceptions about increased glove-wearing in response to risk of HIV infection.

Glove-wearing attitudes of 375 physicians, representing 56% of all physicians surveyed, were ascertained. Although the majority were comfortable with their current glove use, 33% preferred wearing them more frequently. The most common reasons for not wearing gloves were a low likelihood of disease transmission and fear of offending patients. Many physicians felt that more frequent glove use in examining human immunodeficiency virus- (HIV)-positive patients might reduce rapport and diminish the adequacy of physical examination procedures, but only 11% felt that increased glove use would compromise overall care of HIV-positive patients. With regard to all patients, 33% felt that increased glove use in examinations would compromise care. Additionally, 56% of physicians stated that they were somewhat concerned about HIV infection. Glove-wearing preferences were significantly associated with greater concern about infection, a younger age and more frequent exposure to blood and body secretions. Contact with high-risk patient groups was not associated with glove-wearing preferences.

Substance abuse and mental health status of homeless and domiciled low-income users of a medical clinic.

Data were collected on indicators of mental health status and substance abuse among 214 homeless and 250 domiciled but impoverished patients who sought care in a community medical clinic in a California beach community. Although both groups had a high prevalence of problems, homeless patients were significantly more likely to have been hospitalized for alcohol or mental problems, to have been arrested because of drinking, and to have experienced delirium tremens. Homeless persons were also more likely to have made a suicide attempt, to have experienced recent psychotic symptoms, and to be dissatisfied with life. The findings suggest that primary medical care settings serving the poor and homeless may present an excellent opportunity for delivering mental health services and that psychiatrists should expand their involvement in such settings.

First nursing home admissions: time spent at home and in institutions after discharge.

We tracked 96 percent of a sample of 1,942 nursing home patients admitted to a nursing home for the first time in 1982-83. Patients discharged alive from the nursing home were followed for two years or until death. The relative time spent at home, in hospitals, and in skilled nursing facilities is reported. Of the 705 patients discharged from their initial nursing home admission to homes in the community, about 50 percent made only one transfer and only 15 percent made four or more transfers. Of the 509 discharged to a hospital, 26 percent died there and 37 percent of the 374 survivors made four or more moves in the next two years. In all, 1,332 patients were discharged alive and they spent almost two-thirds of the subsequent two years, or their remaining lifetimes, in the community. Of those who transferred only once, over two-thirds of their follow-up time was spent in their own homes. Policies concerned with long-term care should use some type of actuarial data base to successfully plan and implement long-term care insurance.

Professional vs. personal factors related to physicians' attitudes toward drug testing.

Questionnaires concerning attitudes toward alcohol and drug testing in the workplace, personal experiences with these substances, professional experiences in treating abuses, religious and political ideology and other personal and professional characteristics were completed by 303 internists, family physicians, gastroenterologists and psychiatrists. Drug testing was most favored by those who more strongly believed in the efficacy of treatment for abusers, the seriousness of the drug problem, the illegality of drug abuse and that marijuana use should not be permissible. Many other personal but almost no professional characteristics were correlated with attitudes toward drug testing. Physicians' opinions about drug testing strongly reflected personal ideologies rather than medical training or clinical experience.
