Incorporating education on palliative care into the long-term care setting. National Consensus Conference on Medical Education for Care Near the End of Life.

Approximately one-third of all Americans will pass through a long-term care facility before they die, and many who require palliative care will reside there during the final weeks and months of their lives. In order to address this need, the unique characteristics of long-term care facilities are outlined, and the incentives for all levels of academic institutions to offer education in that setting are presented.

Targeting and quality of nursing home care. A five-nation study.

The objective of this study was to demonstrate that appropriate targeting and quality monitoring of institutional care of the elderly is possible using person-based information on residents of nursing homes. This cross-sectional study used Minimum Data Set (MDS) assessments of nursing home residents in 6 US states, Copenhagen, Reykjavik, and selected locations in Italy and Japan. The outcome measures were life expectancy at age 65, population over 65, percentage over 65's in nursing homes, and clinical characteristics of nursing home residents from a multinational database of RAI/MDS assessments. We found that Japan has the highest life expectancy, and the second lowest expenditure on health care. The United States has the highest expenditure on health care and intermediate life expectancy. Italy has the highest proportion of population over 65 and the lowest proportion of over 65's in nursing homes. Iceland, a relatively young country, has the highest proportion of over 65's in nursing homes. Residents in Italy and the United States had the most severe physical, cognitive and clinical characteristics, those in Iceland the least. There was wide variation in markers of quality of care, with no country either uniformly good or bad across multiple measures. In conclusion, headline statistics comparing nations' percentage of Gross Domestic Product (GDP) spent on health care, age structure of the population, percentage of over 65's in nursing homes and clinical characteristics bear no consistent relationship. Local policy and practice also affect quality of care. Standardized assessment enables comparisons at local, national and international levels making possible further research on targeting and the appropriate use of institutional care, thus permitting a range of efficiency measures to be developed to inform policy.

Management of pain in elderly patients with cancer. SAGE Study Group. Systematic Assessment of Geriatric Drug Use via Epidemiology.

CONTEXT: Cancer pain can be relieved with pharmacological agents as indicated by the World Health Organization (WHO). All too frequently pain management is reported to be poor. OBJECTIVE: To evaluate the adequacy of pain management in elderly and minority cancer patients admitted to nursing homes. DESIGN: Retrospective, cross-sectional study. SETTING: A total of 1492 Medicare-certified and/or Medicaid-certified nursing homes in 5 states participating in the Health Care Financing Administration's demonstration project, which evaluated the implementation of the Resident Assessment Instrument and its Minimum Data Set. STUDY POPULATION: A group of 13 625 cancer patients aged 65 years and older discharged from the hospital to any of the facilities from 1992 to 1995. Data were from the multilinked Systematic Assessment of Geriatric Drug Use via Epidemiology (SAGE) database. MAIN OUTCOME MEASURES: Prevalence and predictors of daily pain and of analgesic treatment. Pain assessment was based on patients' report and was completed by a multidisciplinary team of nursing home personnel that observed, over a 7-day period, whether each resident complained or showed evidence of pain daily. RESULTS: A total of 4003 patients (24%, 29%, and 38% of those aged > or =85 years, 75 to 84 years, and 65 to 74 years, respectively) reported daily pain. Age, gender, race, marital status, physical function, depression, and cognitive status were all independently associated with the presence of pain. Of patients with daily pain, 16% received a WHO level 1 drug, 32% a WHO level 2 drug, and only 26% received morphine. Patients aged 85 years and older were less likely to receive morphine or other strong opiates [corrected] than those aged 65 to 74 years (13% vs 38%, respectively). More than a quarter of patients (26%) in daily pain did not receive any analgesic agent. Patients older than 85 years in daily pain were also more likely to receive no analgesia (odds ratio [OR], 1.40; 95% confidence interval [CI], 1.13-1.73). Other independent predictors of failing to receive any analgesic agent were minority race (OR, 1.63; 95% CI, 1.18-2.26 for African Americans), low cognitive performance (OR, 1.23; 95% CI, 1.05-1.44), and the number of other medications received (OR, 0.65; 95% CI, 0.5-0.84 for 11 or more medications). CONCLUSIONS: Daily pain is prevalent among nursing home residents with cancer and is often untreated, particularly among older and minority patients.

Comparison of teleconsultations and face-to-face consultations: preliminary results of a United Kingdom multicentre teledermatology study.

The objective of this multicentre study was to undertake a systematic comparison of face-to-face consultations and teleconsultations performed using low-cost videoconferencing equipment. One hundred and twenty-six patients were enrolled by their general practitioners across three sites. Each patient underwent a teleconsultation with a distant dermatologist followed by a traditional face-to-face consultation with a dermatologist. The main outcome measures were diagnostic concordance rates, management plans and patient and doctor satisfaction. One hundred and fifty-five diagnoses were identified by the face-to-face consultations from the sample of 126 patients. Identical diagnoses were recorded from both types of consultation in 59% of cases. Teledermatology consultations missed a secondary diagnosis in 6% of cases and were unable to make a useful diagnosis in 11% of cases. Wrong diagnoses were made by the teledermatologist in 4% of cases. Dermatologists were able to make a definitive diagnosis by face-to-face consultations in significantly more cases than by teleconsultations (P = 0.001). Where both types of consultation resulted in a single diagnosis there was a high level of agreement (kappa = 0.96, lower 95% confidence limit 0.91-1.00). Overall follow-up rates from both types of consultation were almost identical. Fifty per cent of patients seen could have been managed using a single videoconferenced teleconsultation without any requirement for further specialist intervention. Patients reported high levels of satisfaction with the teleconsultations. General practitioners reported that 75% of the teleconsultations were of educational benefit. This study illustrates the potential of telemedicine to diagnose and manage dermatology cases referred from primary care. Once the problem of image quality has been addressed, further studies will be required to investigate the cost-effectiveness of a teledermatology service and the potential consequences for the provision of dermatological services in the U.K.

Report on the Fifth International Workshop on Chromosome 9 held at Eynsham, Oxfordshire, UK, September 4-6, 1996.

The Fifth International workshop on chromosome 9 comprised a gathering of 36 scientists from seven countries and included a fairly even distribution of interests along chromosome 9 as well as a strong input from more global activities and from comparative mapping. At least eight groups had participated in the goal set at the previous workshop which was to improve the fine genetic mapping in different regions of chromosome 9 by meiotic breakpoint mapping in allocated regions and this has resulted in some greatly improved order information. Excellent computing facilities were available and all contributed maps were entered not only into SIGMA (and thence submitted to GDB) but also into a dedicated version of ACEDB which can be accessed on the Web in the form of one of 28 slices into which the chromosome has been arbitrarily divided. It was generally agreed that the amount of data is now overwhelming and that the integration and validation of all data is not only unrealistic in a short meeting but probably impossible until the whole chromosome has been sequenced and fully annotated. Sequence-ready contigs presented at the meeting totalled about 3 MB which is about one fiftieth of the estimated length. The single biggest barrier to integration of maps is the problem of non-standard nomenclature of loci. In the past 2 workshops efforts have been made to compare traditional 'consensus' maps made by human insight (still probably best for small specific regions) with those generated with some computer assistance (such as SIGMA) and those generated objectively by defined computer algorithms such as ldb. Since no single form of map or representation is entirely satisfactory for all purposes the maps reproduced in the published version of the report are confined to one of the genetic maps, in which Genethon and older markers have been incorporated, a Sigma map of the genes as symbols together with a listing of known 'disease' genes on chromosome 9, and a revised assessment of the mouse map together with a list of mouse loci predicted to be on human chromosome 9. One of the 28 ACEDB slices is also shown to illustrate strengths and weaknesses of this approach. Workshop files include not only all maps available at the time but also details of loci and details of the meiotic breakpoints in the CEPH families (http:/(/)www.gene.ucl.ac.uk/scw9db.shtml) .

Nursing homes in 10 nations: a comparison between countries and settings.

AIM: to illustrate demographic differences and recent trends in the provision and structure of long-term care systems in the 10 countries participating in the Resident Assessment Instrument studies (Denmark, France, Iceland, Italy, Japan, The Netherlands, Sweden, Switzerland, the UK and the USA). METHOD: data were assembled from government documents, statistical yearbooks and articles from journals; supplemental data on long-term care and nursing homes were solicited from colleagues. RESULTS: All 10 countries are developed nations with high life-expectancies. Sweden has the oldest and Iceland the youngest population in this study, with Japan showing the highest ageing rates over the next three decades. Between 2 and 5% of elderly people reside in nursing homes. Interestingly, Iceland, as the 'youngest country' in this study, has the highest rate of institutionalization (living in residential or nursing homes), while the 'oldest country' (Sweden) has a low rate of institutionalization. In all countries the support ratio (number of elderly people per 100 younger adults) is high and increasing rapidly. CONCLUSIONS: no relation appears to exist between the ageing status of a country and the number of nursing home beds. Institutionalization rates among the nations studied differ even more, due at least in part to differences in the organization and financing of long-term care services, in the amount of responsibility assumed in the care for disabled elderly people by each sector and the availability of long-term care beds. Facing a rapid ageing of their population, many countries are in the process of health and social care reforms.

Comprehensive clinical assessment in community setting: applicability of the MDS-HC.

OBJECTIVE: To describe the results of an international trial of the home care version of the MDS assessment and problem identification system (the MDS-HC), including reliability estimates, a comparison of MDS-HC reliabilities with reliabilities of the same items in the MDS 2.0 nursing home assessment instrument, and an examination of the types of problems found in home care clients using the MDS-HC. DESIGN: Independent, dual assessment of clients of home-care agencies by trained clinicians using a draft of the MDS-HC, with additional descriptive data regarding problem profiles for home care clients. SETTING AND PARTICIPANTS: Reliability data from dual assessments of 241 randomly selected clients of home care agencies in five countries, all of whom volunteered to test the MDS-HC. Also included are an expanded sample of 780 home care assessments from these countries and 187 dually assessed residents from 21 nursing homes in the United States. MEASUREMENTS: The array of MDS-HC assessment items included measures in the following areas: personal items, cognitive patterns, communication/hearing, vision, mood and behavior, social functioning, informal support services, physical functioning, continence, disease diagnoses health conditions and preventive health measures, nutrition/hydration, dental status, skin condition, environmental assessment, service utilization, and medications. RESULTS: Forty-seven percent of the functional, health status, social environment, and service items in the MDS-HC were taken from the MDS 2.0 for nursing homes. For this item set, it is estimated that the average weighted Kappa is .74 for the MDS-HC and .75 for the MDS 2.0. Similarly, high reliability values were found for items newly introduced in the MDS-HC (weighted Kappa = .70). Descriptive findings also characterize the problems of home care clients, with subanalyses within cognitive performance levels. CONCLUSION: Findings indicate that the core set of items in the MDS 2.0 work equally well in community and nursing home settings. New items are highly reliable. In tandem, these instruments can be used within the international community, assisting and planning care for older adults within a broad spectrum of service settings, including nursing homes and home care programs. With this community-based, second-generation problem and care plan-driven assessment instrument, disability assessment can be performed consistently across the world.

The elderly: the single greatest achievement of mankind.

The single greatest achievement of mankind is very likely the increase in life expectancy which has occurred in the twentieth century. Coupled with a decline in the birth rate worldwide, the mean age of most nations is rapidly increasing and the old (especially the old-old, those 80 years of age and over) represent an increasing percentage of the dependent population of the world. Although the ageing of the population will have ramifications for almost all aspects of society, those concerned with the provision of health care are especially affected. With chronic disease replacing acute illness, and costs of care mounting, health-care providers will require a comprehensive assessment of its older citizens so as to be able to provide cost-effective care across all sites, be that location a hospital or, more frequently, the home. The development of such capabilities is already under way by the InterRA1 group, an international group of investigators.

Effect of resuscitation solutions on the immune status of dogs in hemorrhagic shock.

The purpose of this study is to examine the effects of three different types of fluid resuscitation on the immune system of dogs in hemorrhagic shock. Using a modified Wigger shock model, 18 conditioned male dogs were bled to mean arterial blood pressure of 60 mm Hg for 90 minutes and placed into three groups based on the resuscitative method. Group I: Crystalloid Resuscitation; Group II: Autotransfusion; Group III: Banked Blood. Laboratory methods for immune status evaluation included total lymphocyte count, T4/T8 ratio, total serum immunoglobulins, and immunoglobulin electrophoresis. These values were obtained pre-hemorrhagic shock, just before resuscitation, and subsequently on days 1, 4, and 7. Humoral immunity, represented by total serum immunoglobulin levels (IgA, IgG, IgM), was higher in Groups II and III when compared with group I on all post-resuscitation days. IgA and IgM levels were higher in Group III compared with Groups I and II. IgG level was higher in Group II compared with Groups I and III. Cellular immunity was also affected by transfusion. Total lymphocyte count was increased in Group II on Day 1; however, the three groups were similar with respect to this variable on subsequent days. The absolute T4 helper cell level in Group II was similar to Groups I and III until Day 7, at which time the level became higher in Group II.(ABSTRACT TRUNCATED AT 250 WORDS)
