Socioeconomic and living conditions are determinants of hip fracture incidence and age occurrence among community-dwelling elderly.

UNLABELLED: In this prospective, 10-year study in community-dwelling elderly aged 50 years and over, hip fracture incidence and accordingly age at hip fracture were inversely associated with the area-level income, independently of the geographical area. Age at hip fracture also depended of marital status but in a gender-specific way. PURPOSE: The purpose of this study is to investigate the impact of socioeconomic and living conditions on hip fracture incidence and age occurrence among community-dwelling elderly. METHOD: Between January 1991 and December 2000, 2,454 hip fractures were recorded in community-dwelling adults aged 50 years and over in the Geneva University Hospital, State of Geneva, Switzerland. Median annual household income by postal code of residence (referred to as area-level income) based on the 1990 Census was used as a measure of socioeconomic condition and was stratified into tertiles (< 53,170; 53,170-58,678; and ≥ 58,678 CHF). Hip fracture incidence and age occurrence were calculated according to area-level income categories and adjusted for confounding factors among community-dwelling elderly. RESULTS: Independently of the geographical area (urban versus rural), community-dwelling persons residing in areas with the medium income category presented a lower hip fracture incidence [OR 0.91 (0.82-0.99), p = 0.049] compared to those from the lowest income category. Those in the highest income category had a hip fracture at a significant older age [+1.58 (0.55-2.61) year, p = 0.003] as compared to those in the lowest income category. Age at hip fracture also depended on marital status but in a gender-specific way, with married women fracturing earlier. CONCLUSIONS: These results indicate that incidence and age occurrence of hip fracture are influenced by area-level income and living conditions among community-dwelling elderly. Prevention programs may be encouraged in priority in communities with low income.

Reversal of the hip fracture secular trend is related to a decrease in the incidence in institution-dwelling elderly women.

UNLABELLED: In this prospective 10-year study in elderly aged 60 years and over, there was a 1.3% per year reduction in the standardized incidence of hip fracture in women but not in men. This decrease was mainly due to changes in the standardized incidence of hip fracture in institution-dwelling women. INTRODUCTION: A decrease in age-adjusted hip fracture incidence has been recently demonstrated in some countries. Since a large proportion of hip fractures occur in nursing homes, we analyzed whether this decreasing trend would be more detectable in institution-dwelling elderly compared with community-dwelling elderly. METHODS: All hip fracture patients aged 60 years and over were identified in a well-defined area. Incidence of hip fracture, age- and sex-adjusted to the 2000 Geneva population, was computed in community- and institution-dwelling elderly. RESULTS: From 1991 to 2000, 1,624 (41%) hip fractures were recorded in institutionalized-dwelling elderly and 2,327 (59%) in community-dwelling elderly. The standardized fracture incidence decreased by 1.3% per year in women (p = 0.039), but remained unchanged in men (+0.5%; p = 0.686). Among institution-dwelling women, hip fracture incidence fell by 1.9% per year (p = 0.044), whereas it remained stable among community-dwelling women (+0.0%, p = 0.978). In men, no significant change in hip fracture incidence occurred among institution- or community-dwelling elderly. CONCLUSIONS: The decrease in the standardized hip fracture incidence in institution-dwelling women is responsible for the reversal in secular trend. Future research should include stratification according to the residential status to better identify the causes responsible for the trend in hip fracture incidence.

Incidence of hip fracture over a 10-year period (1991-2000): reversal of a secular trend.

INTRODUCTION: Hip fractures are a major cause of burden associated with osteoporosis in terms of mortality, disability, and costs. With the ageing of the population, a marked increase in the number of fractures is expected. Furthermore, many studies reveal an increase of the age-adjusted hip fracture incidence. We specifically examined secular changes in the incidence of hip fracture in women and men aged 50 years and over in the well-defined area of Geneva, Switzerland. MATERIALS AND METHODS: All hip fractured patients were retrospectively identified from the computer medical records of the main hospital, which is receiving 95% of hip fractures occurring in a well-defined area. RESULTS: From 1991 to 2000, 4115 hip fractures were recorded in 2981 women and 822 men with a mean age (+/-S.D.) of 83.1+/-8.9 and 78.3+/-11.6 years, respectively. A second hip fracture occurred in 276 women (9.3%) and 36 men (4.4%), on average 2.1+/-1.9 (median 1.44) years after the first event without gender difference. The overall incidence of hip fractures was 455 (95% CI: 439-471) per 100,000 person-years in women and 153 (95% CI: 143-163) in men. The number of hip fractures remained constant (412 (95% CI: 397-426)), but the mean age of these patients increased each year by 0.13 year in women (p=0.019) and by 0.04 year in men (NS). Furthermore, the age-adjusted incidence of hip fractures, standardized to the 2000 Geneva population, decreased significantly by 1.4% (95% CI: -2.6 to -0.1) per year in women (p=0.021), but remained stable in men (0.5% (95% CI: -1.7 to +2.8) per year, p=0.66). The overall female/male ratio of hip fracture incidence was 2.99 (95% CI: 2.80-3.18, p<0.001) and significantly decreased by 0.07 (95% CI: -0.13 to -0.01) per year (p=0.024). CONCLUSION: Despite an increase in the population at risk and in the mean age of hip fractured women, there was a significant decrease in age-adjusted incidence in women but not in men. These results may suggest a reversal of the previously observed secular trend.

Evaluation of the age-adjusted incidence of hip fractures between urban and rural areas: the difference is not related to the prevalence of institutions for the elderly.

As many as 40% of hip fractures occur in institutions for the elderly. Several studies have demonstrated a higher age-adjusted incidence of hip fractures in urban areas compared with rural areas. To assess whether this difference could be due to a preferential location of institutions for the elderly in urban areas, we compared the incidence of hip fractures over a 5-year period in urban versus rural areas, as defined according to the population density (urban > 15 inhabitants/ha2). We then determined the age-adjusted incidence of hip fractures in institutional-dwelling elderly and home-dwelling elderly. Hip fracture incidence was 100.0/100,000 (150.5 in women and 43.8 in men) in urban areas, and 71.0/100,000 (107.2 in women and 32.8 in men) in rural areas (p<0.001). When only those patients living in their own homes were analyzed, the incidence was 66.7/100000 (94.6 in women and 35.7 in men) in urban regions and 36.8/100,000 (49.6 in women and 23.4 in men) in rural areas (p<0.001), a difference of even greater magnitude than when both home-dwelling and institutional-dwelling residents were considered together. In a logistic regression model including age class, gender, urban or rural areas and institutionalization for inhabitants 65 years of age and older, urban residents have a 31% significantly (p<0.001) higher incidence of hip fracture compared with rural residents; women have a 79% significantly (p<0.001) higher incidence of hip fracture compared with men; and institutional-dwelling elderly have a 351% significantly (p<0.001) higher incidence of hip fracture compared with home-dwelling elderly. These results confirm the existence of a higher age-adjusted incidence of hip fractures in urban compared with rural areas. Since this difference is increased when patients living at home were analyzed separately, it indicates that the difference between urban and rural areas is not due to a preferential urban location of institutions for the elderly.

Nutrition and oral health.

Reduced chewing function in community-dwelling older people with adequate general health is linked to having fewer than 20 teeth present or to wearing removable dentures. By chewing for longer periods of time or swallowing larger food particles they are normally able to compensate for the impaired function. The masticatory function can be restored by adequate prosthetic therapy, which results in increased activity of the masticatory muscles during chewing and reduces the chewing time and the number of chewing strokes until swallowing. In frail or dependent elderly people undernutrition is prevalent because of health problems, reduced appetite and poor quality of life. Poor oral health and xerostomia are often associated with a reduced body mass index and serum albumin level and the avoidance of difficult-to-chew foods. Maintenance or re-establishment of masticatory function is an integral part of the medical health care of these patients, with the aim of improving their nutritional status and quality of life.

[Weight of practical, conceptual and ethical problems related to spoon feeding of aged patients with diminished mental capacity]. / Poids des problèmes pratiques, conceptuels et éthiques liés à l'alimentation à la cuiller des patients âgés en perte de capacités.

This qualitative study is based on twenty observations. Problems with spoon feeding of hospitalized, elder, demented patients are rarely considered. This study aims at analyzing their practical, conceptual and ethical specificities. Ten patients were directly observed and their ten nurses of reference responded to structured interviews. We established three significant observations: 1. The use of spoon feeding appeared inoperative as it did not help resolve the problems that were invoked to justify its implementation. 2. Three months after the observations six patients were deceased, three were able to feed themselves and one did not improve. 3. In all observed cases, spoon feeding was initiated as a tacit evolution, with no formal decision process. To avoid this dead end we consider it indispensable to evolve this feeding practice from its current state of unchallengeable humane duty to the conceptual level of patient care, and to develop evaluation tools which will enable its integration into a structured strategy of nursing interventions.

[Advance directives, a tool to humanize care]. / Les directives anticipées, un outil d'humanisation des soins.

The relationship between the patient and a medical care giver is complex specially as it implies to the human, juridical and practical points of view. It depends on legal and deontological considerations, but also on professional habits. Today, we are confronted to a fundamental modification of this relationship. Professional guidelines exist, but are rarely applied and rarely taught in universities. However, patients are eager to move from a paternalistic relationship to a true partnership, more harmonious and more respectful of individual values ("value based medicine"). Advance directives give us an opportunity to improve our practices and to provide care consistent with the needs and wishes of each patient.

In addition to its mainly home-based clinical activity, the Geriatric Polyclinic has chosen to develop tree programmes with a specific activity. Their common objectives being promoting heath and maintaining home-based treatment in the best conditions and for as long as possible. This article describes these programmes.

Elevated serum vitamin B12 levels associated with CRP as a predictive factor of mortality in palliative care cancer patients: a prospective study over five years.

The relationship between vitamin B12 levels and survival was studied in a group of 161 terminally ill cancer patients who were recruited consecutively between 1988 and 1989. Their average age was 74.7 years. The length of survival decreased with the increase in serum vitamin B12 levels (P = 0.0015, Cox model). In multivariate analyses, C-reactive protein (CRP) was the most important prognostic factor in this population, and vitamin B12 provided information independent of CRP in predicting survival. These data indicate that an elevated serum vitamin B12 level is a predictive factor for mortality in patients with cancer, independent of CRP or other factors. Multiplying it by the CRP makes it possible to create a new, easy-to-use prognostic index, which can distinguish different levels of mortality risk at three months.

Refrigerator content and hospital admission in old people.

We assessed whether the refrigerator contents of elderly people could be related to subsequent admission to hospital. 132 patients aged over 65 years had a thorough assessment of their refrigerator contents and the numbers and dates of admission were recorded. Elderly people with empty refrigerators were more frequently admitted (p=0.032) in the month after assessment and three times sooner than those who did not have empty refrigerators (34 vs 100 days, p=0.002).

Relationship between oral health and nutrition in very old people.

OBJECTIVE: To evaluate the relationship between oral health status and nutritional deficiency. DESIGN: Cross-sectional clinical study. SUBJECTS: 324 institutionalized frail older adults (mean age 85). MEASUREMENTS: Structured oral examination including an evaluation of mucosa, periodontal state, caries prevalence and denture quality. The nutritional status was assessed using serum albumin concentration and the body mass index. Physical dependence was assessed using the Barthel index. To identify oral health disorders associated with markers of malnutrition we performed the Pearson chi2 test separately for edentulous and dentate patients. Subjects with at least one of the identified oral disorders were classified as having compromised oral functional status. RESULTS: About two-thirds of the subjects were functionally dependent and half had either a body mass index <21 kg/m2 or serum albumin <33 g/l. Among the edentulous, wearing dentures with defective bases or not wearing dentures at all were the factors most associated with malnutrition. In dentate subjects, corresponding identifiers were the number of occluding pairs of teeth (five or fewer, either natural or prosthetic), the number of retained roots (four or more), and the presence of mobile teeth. According to these criteria, 31% of the subjects had a compromised oral functional status. This was more frequently found in dependent subjects (37%) than semi-dependent subjects (18%; odds ratio, 2.6; 95% confidence interval, 1.4-4.8). Those with compromised oral functional status had a significantly lower body mass index and serum albumin concentration. CONCLUSION: Specific detrimental oral conditions are associated with nutritional deficiency in very old people.

The effects of morphine on dyspnea and ventilatory function in elderly patients with advanced cancer: a randomized double-blind controlled trial.

BACKGROUND: Dyspnea represents a very frequent and distressing symptom in patients with advanced cancer. This study was undertaken to assess the efficacy of morphine on dyspnea and its safety for ventilatory function in elderly advanced cancer patients. PATIENTS AND METHODS: Nine elderly patients with dyspnea due to lung involvement were randomized to receive either morphine subcutaneously (5 mg in seven opioid-naïve patients and 3.75 mg in two patients on top of their regular oral dose of 7.5 mg q4 h) or placebo on day 1. On day 2, they were crossed over to receive the alternate treatment. Dyspnea was assessed every fifteen minutes using a visual analogue scale (VAS: 0-100 mm) and the ordinal scale developed by Borg (0-10 points). Pain, somnolence and anxiety were assessed using VAS. Respiratory effort, respiratory rate and oxygen saturation were also measured repeatedly. RESULTS: Mean changes in dyspnea 45 minutes after injection were -25 +/- 10 mm and -1.2 +/- 1.2 points for morphine, versus 0.6 +/- 7.7 mm (P < 0.01) and -0.1 +/- 0.3 points (P = 0.03) for placebo on VAS and Borg scale, respectively. No relevant changes were observed in somnolence, pain, anxiety, respiratory effort and rate, and oxygen saturation. CONCLUSIONS: Morphine appears effective for cancer dyspnea, and it does not compromise respiratory function at the dose level used.

Reasons for dissatisfaction: a survey of relatives of intensive care patients who died.

OBJECTIVE: To describe the reasons for eventual dissatisfaction among the families of patients who died in the intensive care unit (ICU), regarding both the assistance offered during the patient's stay in the hospital and the information received from the medical staff. DESIGN: Cross-sectional descriptive study, which was conducted after a survey using a questionnaire. SETTING: Interdisciplinary ICU (n = 8 beds) at San Giovanni Hospital in Bellinzona (CH). SUBJECTS: Three-hundred ninety families of patients who died in the ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A postal questionnaire (n = 43 questions) was sent to the families of 390 patients who died in the ICU during 8 yrs (1981 to 1989). The results referred to 123 replies: a) 82.6% of the respondents expressed no criticism of the patient's hospital stay; b) 90% considered the patient's treatment was adequate; c) 17% felt that the information received concerning diagnosis was insufficient or unclear; and d) 30% (particularly close relatives and those relatives who were informed of the death by telephone and not in person) expressed dissatisfaction regarding the information received on the cause of death. CONCLUSIONS: Our survey found that the relatives of patients who died were most dissatisfied with the care received according to: a) the type of death (e.g., sudden death vs. death preceded by a gradual deterioration in the patient's condition); and b) the manner in which the relatives were notified of the death (in person vs. by telephone). The personal characteristics of the people interviewed, such as gender and the closeness of their relationship to the deceased, also seem to have some bearing on the opinions expressed. A high percentage of respondents were satisfied with the treatment received by their dying relative and the information conveyed by caregivers. Nevertheless, the dissatisfaction expressed by some respondents indicates a need for improvement, especially in communicating information to the relatives of these patients.

Associations between malnutrition, poor general health and oral dryness in hospitalized elderly patients.

OBJECTIVE: To obtain information about the possible relationship between symptoms and signs of oral dryness and malnutrition/poor general health in hospitalized older people. DESIGN: A cross-sectional clinical investigation with measurements of unstimulated salivary flow rates (USFR), stimulated salivary flow rates (SSFR), nutritional status, serum albumin concentration and an evaluation of symptoms of oral dryness and loss of appetite by a questionnaire. SUBJECTS AND METHODS: A cohort of 99 elderly, non-psychiatric patients hospitalized for medical reasons; collection of demographic and health data from medical files, collection of USFR and SSFR, measurements of body mass index (BMI), lean body mass, fat body mass, serum album in concentration; completion of a questionnaire related to symptoms of oral dryness and the patients' appreciation of their nutritional status. MAIN OUTCOME MEASURES: SSFR and USFR. RESULTS: Mean age of the 99 patients was 82.5 +/- 4.0 years. Anthropometric examinations indicated malnutrition of severe or intermediate degree in about 50% while 46% showed moderately and 40% severely reduced albumin. Loss of appetite was present in 54% and 51% complained of oral dryness; 17% had an USFR <0.1 ml/min and 26% a SSFR <0.5 ml/min. Significant associations were found between (i) reduced salivary flow rate, malnutrition and reduced serum albumin concentration, (ii) recent loss of appetite and low serum album in concentration and (iii)complaints of oral dryness and reduced salivary flow rates. There were also significant associations between complaints of oral dryness, loss of appetite and low BMI. CONCLUSION: Reduced salivary secretion and complaints of oral dryness could be signs of poor nutritional or general health status of elderly patients. Reduced salivary secretion and feeling of oral dryness could have a negative effect on alimentation, appetite and oral comfort.

[Medicine and humanism: clinical ethics and the community dimension of geriatrics]. / Médecine et humanisme: l'éthique clinique et la gériatrie à dimension communautaire.

Clinical ethics is generally related to the clinical bedside activity. Clinical ethics constitutes one aspect of bioethics. In particular, its aim consists in facilitating the solving of conflicts of values in practical care. By encouraging effective communication and discussion within the interdisciplinary team, geriatricians will be able to make adequate diagnostic and therapeutic interventions, in accordance with the fundamental desire of the patient and her or his family.
