Rural-urban differences in end-of-life care: the use of feeding tubes.

Efforts to improve end-of-life care have increased during the past decade. The goals of these efforts include increasing patient autonomy and reducing or more selectively using intensive medical interventions near the end of life. In this light, examination of community-to-community variations in end-of-life practices may serve to clarify the values and goals of different populations, as well as the roles of patients, families and professionals in bringing about specific patterns of medical care. This study examined the use of feeding tubes among Kansas nursing home residents between Jan. 1, 1994, and June 30, 1998 (n = 78,895), using the Minimum Data Set. Residents with very severe, persistent and irreversible cognitive impairment (n = 4,847) were included in the study population. The location of nursing homes in urban, midsize and rural counties was an independent variable. Feeding tubes were used in 19.3 percent of the urban nursing home residents, 8.0 percent of the residents in midsize counties and 6.4 percent of the rural residents. The rate of feeding tube use was significantly higher in urban counties for most subpopulations, including men, women, whites, nonwhites, and those eligible and ineligible for Medicaid. The observed rural-urban differences in feeding tube use near the end of life may be associated with differences in access to surgical or nursing services, differences in the relationships between providers and consumers of care in different communities or differences in rural and urban cultures. Qualitative research may be useful in clarifying the roles of each of these factors.

The need to revise assumptions about the end of life: implications for social work practice.

During the 20th century the experience of dying changed dramatically. At the beginning of the 1900s, dying and death were integral parts of the life experience of most people at any age. Many deaths occurred at home following a short course of illness largely unaffected by the limited medical care available. At the beginning of the 21st century, in many cases, the process of dying has become invisible. Today, most deaths occur in old age. Social workers have a key role as "context interpreters" in helping people at the end of life and their families understand the natural course of the illness, the process of dying, and the advantages and drawbacks of medical interventions. An expanded role for social workers in helping people comprehend the medical and social contexts within which they face end-of-life decisions is discussed.

Ethnicity and end-of-life care: the use of feeding tubes.

BACKGROUND: Blacks utilize many health care services at lower rates than do Whites. However, in end-of-life care, the situation is frequently reversed, with Blacks using life-sustaining interventions at higher rates than do Whites. We investigated the use of feeding tubes in very severely cognitively impaired nursing-home residents, and examined the findings in light of previous studies on the role of ethnicity in end-of-life decision making. DESIGN AND METHODS: We performed a descriptive, cross-sectional population-based study of residents in Kansas nursing homes from January 1994 through June 1998, using Minimum Data Set reports. A total of 4,920 nursing home residents (4,691 White and 229 Black) with very severe and irreversible cognitive impairment comprised the study population. Factors associated with tube use were examined using bivariate and logistic regression tests. RESULTS: Feeding tube use was strongly associated with swallowing difficulties, Black race, urban location of nursing home, stroke, and absence of dementia in multivariate analysis. Feeding tubes were used in 10.1% of White subjects and in 38.9% of Black subjects for an overall rate of 11.5%. Feeding tube use was greater (P<.001) among Black subjects in all demographic and clinical sub-populations examined. CONCLUSIONS: Feeding tube use is significantly more common in Blacks than in Whites. These findings are consistent with published studies of Black-White differences in preferences for medical treatment at the end of life. Future research efforts should examine end-of-life decision making processes directly. Qualitative methods may be useful in generating new hypotheses regarding the role of ethnicity in these decisions.

Tube feeding in nursing home residents with severe and irreversible cognitive impairment.

OBJECTIVES: This study was undertaken to determine the degree to which selected demographic and clinical variables are associated with the use of feeding tubes in older nursing home residents with very severe and irreversible cognitive impairment. DESIGN: Descriptive, cross-sectional, population-based study. SETTING: Kansas nursing homes from January 1, 1994, through June 30, 1998. PARTICIPANTS: A total of 4,997 nursing home residents with very severe and irreversible cognitive impairment comprised the study population. Subjects were identified using data in Minimum Data Set (MDS) reports. Those who were included in the study population were over the age of 65, had two consecutive Cognitive Performance Scale scores of 6, were without evidence of significant subsequent improvement, and were not comatose. MEASUREMENTS: The MDS data on each resident were examined to determine subjects' age, ethnicity, gender, Medicaid eligibility, disease diagnoses, physical functioning, and oral/nutritional status, including feeding tube status. The MDS was also used to determine urban versus rural location of the nursing home. The association between the use of feeding tubes and selected demographic and clinical characteristics was then examined using bivariate and logistic regression tests. RESULTS: Of the 4,997 residents in the study population, 577 (11.6%) had feeding tubes. In multivariate analysis, feeding tube use was found to be associated with swallowing problems (odds ratio (OR) 5.4, 95% confidence interval (CI) 4.3-6.8); urban location of nursing home (OR 2.9, 95% CI 2.3-3.5); non-white race (OR 2.7, 95% CI 1.9-3.6); stroke (OR 2.5, 95% CI 2.0-3.1); and absence of dementia (OR 2.5, 95% CI 2.0-3.1). Feeding tubes were also more weakly associated with age <86 years, male gender, dependency for all activities of daily living, and absence of a living will. Feeding tube use was not found to be associated with chewing problems, Medicaid status, or resuscitation status. CONCLUSIONS: Clinical variables including swallowing problems, stroke, and absence of dementia were strongly associated with the use of feeding tubes in this cross-sectional, population-based study. In addition, urban location of nursing home and non-white race were significantly associated with feeding tubes. These findings suggest that feeding tube decisions are strongly influenced by nonclinical factors and invite further investigation.

End-of-life decision making for nursing home residents with dementia.

PURPOSE: To describe families' decision-making processes, both cognitive and affective, regarding end-of-life treatments for nursing home residents with moderately severe to very severe dementia. DESIGN: Naturalistic inquiry provided the framework for this descriptive, qualitative study. METHODS: Four focus groups were conducted in selected nursing homes, in the central part of the United States for a qualitative study. Twenty-eight family members of residents with moderately severe to severe dementia shared their decision-making experiences. Open-ended questions were asked in each focus group. Data were analyzed using content analysis. FINDINGS: Five themes were identified that describe the context of decision making: emotional effect, insult-to-life story, two faces of death, values and goals regarding end-of-life treatments, and the unrecognized trajectory of dying. Family members made decisions in an emotional climate of overwhelming burden and guilt, because their loved one's life had been robbed of personhood, the changes associated with decline from a dementia-related illness were unrecognized as part of a trajectory of dying, death was both a tragedy and a blessing. CONCLUSIONS: Family members had poignant, unresolved emotional needs stemming from their loved one's illness and nursing home placement. Participants were unprepared to make end-of-life treatment decisions and lacked the informational and emotional support of a consistent provider to help with decisions. Family members need assistance in processing difficult and painful emotions, understanding the trajectory of disease, what decisions might impede a natural death, and comfort or palliative care options.

Planning end-of-life care for patients with dementia: roles of families and health professionals.

We examined families' end-of-life decision making and their interactions with health professionals. Twenty-eight family members of institutionalized dementia patients participated in four focus groups. We found that participating family members were not well prepared for their decision-making roles, and that they: 1) experienced substantial burdens and loss in caring for institutionalized elders; 2) had limited understanding of the natural progression of dementing conditions; 3) were uncomfortable in setting goals for their relatives' end-of-life care; 4) had little experience with death, and were ambivalent about the anticipated death of their relative; and (5) reported that they had little substantive communication with health professionals regarding end-of-life care planning. We concluded that many of the needs of such families could be addressed through improved application of the principles of advance care planning, including regular structured discussions, involvement of surrogate decision-makers, and anticipation of clinical decisions. Health professionals should take the lead in 'normalizing' the discussion of death.

Family physicians for underserved areas. The role of residency training.

Graduates of four rural and four urban family practice programs were interviewed to determine the nature of their practices and the factors that had influenced their practice location decisions. All programs gave residents substantial experience providing continuity of care for underserved populations. Of the 158 physicians surveyed, 58 (46%) were working in areas designated as underserved. The percentage of physicians in underserved areas was higher than that reported in other studies and was much higher than would be expected if practice sites were selected on the basis of population distribution alone. Notable differences in personal and practice characteristics were found between the physicians who chose to work in underserved areas and those who did not and between those who established practices in rural and in urban underserved areas.

The challenge of AIDS education for physicians.

Education has been identified as one of our best weapons in the Acquired Immune Deficiency Syndrome (AIDS) epidemic, both to help reduce the spread of the virus and to improve the care of patients with the disease. Medical educators have been asked to take on a difficult task: to assure that physicians acquire the knowledge, skills, and attitudes necessary to make them as effective as possible in dealing with the HIV infection. This article reviews some of the factors which influence the effectiveness of AIDS educational programs for physicians and some of the challenges which medical educators must face.

Factors affecting nutrition training in four family practice residencies.

Nutrition education at the four institutions studied was not highly effective. Not all educators were qualified in terms of education or experience. The individuals were not recruited using suggested faculty search methods, and turnover was high. Nutrition education was part of the distant environment for the family practice resident, rather than in the foreground. Nutrition education should be part of the scheduled activities of residents, so that they do not have to borrow time from patient care and other obligations. Then, the residents could devote their full attention to nutrition and see its importance as equivalent to that of other subspecialties.

Urban AHECs: a comparison with rural AHECs.

The first generation of projects in the Federal Area Health Education Center (AHEC) Program was funded in 1972. Those AHEC projects, located in predominantly rural areas, focused on problems that resulted from the geographic maldistribution of health professionals, especially primary care physicians. Education programs for health professionals, students, and practitioners were used to influence the geographic distribution of health professionals and to improve access to and quality of health care for underserved populations. In 1976, the Congress redrafted the law authorizing the expenditure of funds for AHECs and emphasized that improving access to health care in urban underserved areas also was to be addressed by the program. During the early years of urban AHEC development, it was not clear which lessons learned from rural AHEC experiences could be applied to urban communities and what would be the best focus for AHEC activities in the complex urban environment. Some said that urban areas were so different from rural areas--in economic, racial, and cultural terms and in the subtlety of barriers to health care--as to make the rural AHEC experience largely irrelevant. Others maintained that basic AHEC principles could be applied, regardless of setting, with changes only in tactics to address the problems of the urban inner city. Now that 18 of the total 53 AHECs nationally are urban, and a decade of experience in developing them has been accumulated, it is appropriate to compare the types of educational interventions supported by AHECs in urban and rural environments and the relative priorities of such programs. In this report we examine the experiences of the California AHEC System, which includes 17 urban and rural centers and the 9 medical schools with which they are affiliated. Although the AHEC Program concept was found to be equally applicable to both urban and rural settings, significant differences in implementation were noted. Those differences were evidenced both by relative budgets,such as the large expenditures for undergraduate medical education in urban areas and for nursing in rural areas, and by subtler differences in the types of programs developed within budget categories

A statewide approach to health care personnel maldistribution. The California Area Health Education Center System.

An Area Health Education Center (AHEC) system has been established in California to address the maldistribution of physicians and other health care professionals. The AHEC program uses educational incentives to recruit and retain health care personnel in underserved areas by linking the academic resources of university health science centers with local educational and clinical facilities. The medical schools, working in partnership with urban or rural AHECs throughout the state, are implementing educational programs to attract trainees and licensed professionals to work in underserved communities. The California AHEC project entered its fifth year in October of 1983 with the participation of all eight medical schools and the Charles Drew Postgraduate School of Medicine, 35 other health professions schools, 17 independent AHECs and more than 400 clinical training sites. Educational programs are reaching more than 22,000 students and practicing health professionals throughout California. We review the current status of the California AHEC system and use the AHEC programs at Loma Linda University to illustrate the effect this intervention is having.

Drug-pyridoxal phosphate interactions.

In this review it has been pointed out that vitamin B6 and its vitamers can be involved in many interactions with a number of drugs, as well as with the actions of various endocrines and neurotransmitters. Nutritional deficiencies, especially of vitamins and proteins, can affect the manner in which drugs undergo biotransformation, and thereby may also modify the therapeutic efficacy of certain drugs. The differences between nutritional vitamin B6 deficiency and the hereditary disorder producing pyridoxine dependency are discussed. In addition to a pyridoxine deficiency being able to adversely affect drug actions, the improper supplementation with vitamin B6 can in some instances also adversely affect drug efficacy. A decrease by pyridoxine in the efficacy of levodopa used in the treatment of Parkinsonism is an example. The interrelationships and enzymatic interconversions among pyridoxine vitamers, both phosphorylated and non-phosphorylated, are briefly discussed, particularly regarding their pharmacokinetic properties. The ways in which the normal biochemical functions of vitamin B6 may be interfered with by various drugs are reviewed. (1) The chronic administration of isoniazid for the prevention or treatment of tuberculosis can produce peripheral neuropathy which can be prevented by the concurrent administration of pyridoxine. An acute toxic overdose of isoniazid causes generalized convulsions, and the intravenous administration of pyridoxine hydrochloride will prevent or stop these seizures. (2) The acute ingestion of excessive monosodium glutamate will, in some individuals, cause a group of symptoms including among others headache, weakness, stiffness, and heartburn, collectively known as the 'Chinese Restaurant Syndrome.' These symptoms can be prevented by prior supplementation with vitamin B6. The beneficial effect is ascribed to the correction of a deficiency in the activity of glutamic oxaloacetic transaminase, an enzyme that is dependent on pyridoxal phosphate. Some interesting relationships are pointed out between vitamin B6, picolinic acid, and zinc. It is postulated that the intestinal absorption of zinc is facilitated by picolinic acid, a metabolite of tryptophan. The derivation of picolinic acid from tryptophan depends on the action of the enzyme kynureninase, which is dependent on pyridoxal phosphate; therefore, the adequate absorption of zinc is indirectly dependent on an adequate supply of vitamin B6. The formation of pyridoxal phosphate, on the other hand, appears to be indirectly dependent on Zn2++ which activates pyridoxal kinase.(ABSTRACT TRUNCATED AT 400 WORDS)

PIP: This review examines the interaction of pyridoxal phosphate with select neuroendocrine and neuropharmacological systems and their health related therapeutic implications. Vitamin B6 and its vitamers can be involved in many interactions with a number of drugs as well as the actions of various endocrines and neurotransmitters. Nutritional deficiencies, particularly of vitamins and proteins, can affect the manner in which drugs undergo biotransformation and thus may modify the therapeutic efficacy of certain drugs. In addition to pyridoxine deficiency adversely affecting drug actions, improper supplementation with viatmin B6 can in some instances also adversely affect drug efficacy. A decrease by pyridocxine in the efficacy of levodopa used in the treatment of Parkinsonism is an example. The interrelationships and enzymatic interconversions amony pyridoxine vitamers, both phosphorylated and nonphosphorylated, are briefly discussed, particularly concerning their pharmacokinetic properties. The chronic administration of isoniazid for the prevention or treatment of tuberculosis can produce peripheral neuropathy which can be prevented by the concurrent administration of pyridoxine. An acute toxic overdose of isoniazid causes generalized convulsions, and the intravenous administration of pryidoxine hydrochloride prevents or stops these seizures. The acute ingestion of excessive monosodium glutamate will, in some persons, cause a group of symptoms, including headache, weakness, stiffness, and heartburn, collectively known as the "Chinese Restaurant Syndrome." These symptoms can be prevented by prior supplementation with vitamin B6. It is postulated that the intestinal absorption of zinc is facilitated by picolinic acid, a metabolite of tryptophan. The derivation of picolinic acid from tryptophan depends on the action of the enzyme kynureninase, which is dependent on pyridoxal phosphate. Therefore, the adequate absorption of zinc is indirectly dependent on an adequate supply of vitamin B6. The formation of pyridoxal phospate appears to be indirectly dependent on Zn2++ which activates pyridoxal kinase. Treatment with daily pyridoxine can reverse a state of depression induced in women who take oral contraceptives (OCs). 1 hypothesis to explain this effect is that the OC is somehow causing a deficiency of seroton serotonin in the brain and that the vitamin B6 helps to overcome this deficiency through the stimulation of 5-hydroxytryptophan decarboxylase by pyridoxal phosphate. In sum, the stimulation of 5-hydroxytryptophan decarboxylase by pyridoxal phosphate. In sum, pyridoxal phosphate in physiological concentrations seems to function as an endogenous "down regulator" of several receptor sites, including estrogen, progesterone, and androgen.
