The Metropolitan Toronto Regional Geriatric Program: an innovative method of health care delivery.

The co-ordination of hospital services in large metropolitan areas presents a formidable challenge. History, university relationships, geography and a tradition of independence and autonomy mitigate against co-operative regional ventures. A new program is evolving in Metropolitan Toronto which represents a significant change in the delivery of specialized geriatric services. The regional geriatric program has been established with direct funding from the Ontario Ministry of Health and contractual agreements with participating hospitals to provide specific geriatric services. It is a collaborative venture with the participating hospitals and the University of Toronto voluntarily participating in its management and policy direction. Although many issues have yet to be resolved regarding the relationship of the program to the Ministry, between the hospitals and with the community, this model may become prevalent in other areas of specialty services, such as trauma and oncology.

Use of growth factors in the elderly patient with cancer: a report from the Second International Society for Geriatric Oncology (SIOG) 2001 meeting.

Over 70% of the total incidence of cancer recorded in Europe in 1996 was in the elderly population (> or =60 years). Despite such high statistics, elderly cancer patients have often been denied the treatment that younger patients routinely receive. The response of elderly cancer patients to full-dose chemotherapy treatment in several neoplasms is similar to that of younger patients, demonstrating that age should not be a barrier to the administration of potentially curative or palliative chemotherapy. In order to provide optimal treatment to elderly cancer patients, management guidelines are recommended which take into account various factors, such as the physical well-being of the patient, the type of malignancy and any conditions that may hamper compliance with chemotherapy. The evidence-based guidelines of the National Comprehensive Cancer Network (NCCN) in the US recommend that the safest and most effective treatment of cancer in older individuals may be achieved by proper patient selection based on comprehensive geriatric assessment, dose adjustment of renally excreted drugs, prophylactic use of haematopoietic growth factors in patients treated with chemotherapy of dose-intensity comparable to cyclophosphamide/doxorubicin/vincristine/prednisone (CHOP) and maintenance of haemoglobin levels > or =12 g/l. The objective of this article is to report the conclusions of the meeting of the International Society of Geriatric Oncology (SIOG) in September 2001, including the need for geriatric assessment to tailor the management of patients to their personal circumstances and general health and the importance of evidence-based guidelines for the management of elderly cancer patients cannot be over-estimated.

Insomnia in the geriatric patient.

Insomnia in the geriatric patient is unique and complex, requiring a comprehensive and careful evaluation. Insomnia is the most common sleep complaint reported by persons > 60 years. It is defined as the inability to initiate or maintain sleep, and the etiology can be multifactorial. Insomnia in the geriatric patient may be due to a primary sleep disorder, such as obstructive sleep apnea, periodic limb movements in sleep, circadian rhythm disorders, or restless legs syndrome, or it may be secondary to underlying medical or psychiatric conditions, medication effects, or psychosocial factors. When insomnia becomes chronic, it may exacerbate medical and psychiatric illnesses. Insomnia can lead to excessive daytime sleepiness, which may result in disturbed intellect, impaired cognition, confusion, psychomotor retardation, or increased risk of injury, any of which can compromise the patient's quality of life and create social and economic burdens for caregivers. This article discusses the recommended diagnostic and treatment approaches that may be used by the clinician in treating the geriatric patient. Case studies are presented to illustrate diagnoses of insomnia and therapeutic interventions.

Persistent mild cognitive impairment in geriatric depression.

BACKGROUND: Cognitive impairment often occurs with geriatric depression and impairments may persist despite remission of depression. Although clinical definitions of mild cognitive impairment (MCI) have typically excluded depression, a neuropsychological model of MCI in depression has utility for identifying individuals whose cognitive impairments may persist or progress to dementia. METHODS: At baseline and 1-year follow-up, 67 geriatric patients with depression had a comprehensive clinical examination that included depression assessment and neuropsychological testing. We defined MCI by a neuropsychological algorithm and examined the odds of MCI classification at Year 1 for remitted depressed individuals with baseline MCI, and examined clinical, functional and genetic factors associated with MCI. RESULTS: Fifty-four percent of the sample had MCI at baseline. Odds of MCI classification at Year 1 were four times greater among patients with baseline MCI than those without. Instrumental activities of daily living were associated with MCI at Year 1, while age and APOE genotype was not. CONCLUSIONS: These results confirm previous observations that MCI is highly prevalent among older depressed adults and that cognitive impairment occurring during acute depression may persist after depression remits. Self-reported decline in functional activities may be a marker for persistent cognitive impairment, which suggests that assessments of both neuropsychological and functional status are important prognostic factors in the evaluation of geriatric depression.

Relationship between antipsychotic drug use and behavioral and psychological symptoms of dementia in old people with cognitive impairment living in geriatric care.

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) commonly occur among cognitively impaired people in geriatric care. BPSD are often managed with antipsychotic drugs, despite the associated serious health risks. The aim of the present study was to discover factors associated with the use of antipsychotics. METHODS: A cross-sectional study in all geriatric care units in the county of Västerbotten, Sweden, which included 2017 residents aged 65 years and over with cognitive impairment (mean age was 83.5 years). Data were collected from prescription records and observations made by care staff of BPSD among residents during the preceding week. A multivariate regression model was constructed to find factors independently associated with antipsychotic drug use. RESULTS: Eleven factors were independently associated with the use of antipsychotics. Aggressive, verbally disruptive and wandering behavior, hallucinatory and depressive symptoms, male sex, living in a group dwelling for people with dementia, imposed mental workload, the ability to rise from a chair, activities of daily living (ADL) dependency and lower age all correlated significantly. CONCLUSIONS: Antipsychotic drug treatment of old people with cognitive impairment in geriatric care is common, and determined not only by the patient's symptoms but also by factors related more closely to the caregiver and the caring situation. These findings raise important questions about the indications for drug treatment in relation to the patient's quality of life.

Geriatric issues in renal transplantation.

There are an increasing amount of data which are compelling us to consider the issue of age in dealing with decisions regarding both renal transplant recipients and donors. These geriatric issues in transplantation can be summarized as follows: (1) The explosion of a geriatric population of patients with ESRD, in association with data showing a survival advantage of transplantation over wait-listed dialysis patients, demands an increase in expertise in transplantating patients over 60 years old. (2) The critical shortage in cadaveric organ supply is creating a variety of solutions including expanding the donor pool with older kidneys in which long term survival may be shorter than in kidneys from younger donors. (3) The donor shortage, in association with data demonstrating improved survival of living related and unrelated donor transplants, is generating an increased number of older (> 60 years old) individuals who want to donate to a relative, spouse or friend. Future efforts should be directed toward continued research designed to evaluate the efficacy and safety of these trends. We also need to provide improved training in geriatrics for nephrologists so that we and transplant surgeons can deliver better medical care to an aging population of patients with ESRD.

Renal function in the oldest-old on an acute geriatric ward.

AIM: Evaluation of renal function and relation to risk factors for renal failure in very old patients admitted to an acute geriatric ward. METHODS: Retrospective chart review of patients aged 80 years and over, admitted to the acute geriatric ward from August 1998 till August 1999. Recorded data were: age, gender, previous medical history, primary diagnosis, medication use, weight, serum creatinine, BUN, sodium, potassium, cholesterol, urine and ultrasound of the kidney. The creatinine clearance was estimated by the Cockcroft-Gault formula, the glomerular filtration rate by the MDRD equation. RESULTS: 220 (60 males/160 females) patients were included. The mean serum creatinine on admisssion and discharge was 1.17 +/- 0.45 mg/dL and 1.11 +/- 0.48 mg/dL respectively. The mean estimated creatinine clearance in the very old was 38.11 +/- 12.04 mL/min on admission and 39.00 +/- 11.01 mL/min on discharge. Renal failure arbitrarily defined as an estimated creatinine clearance on admission of less than 30 mL/min was found in 26.4% of the patients. Only a significant correlation between failure to thrive and renal failure was found (p < 0.0001). The correlation coefficient between the Cockcroft-Gault and the MDRD formula was r = 0.66 (p < 0.0001); between the Cockcroft-Gault and the reciprocal serum creatinine was r = 0.60 (p < 0.0001) and between the MDRD and the reciprocal serum creatinine was r = 0.87 (p < 0.0001). CONCLUSION: The weak correlation between the Cockcroft-Gault and other estimations of GFR in the acutely ill elderly, confirms the need to have a reliable estimation of glomerular filtration rate in the elderly. Renal failure defined as a Cockgroft-Gault <30 mL/min is found in 26.4% of the oldest-old admitted to an acute geriatric department. The elderly with renal failure is more often admitted for failure to thrive. No great differences were observed between renal function on admission and discharge.

Clinical correlates of response to valproate in geriatric inpatients.

The efficacy of valproate for the management of adults with bipolar disorder has been repeatedly demonstrated in several studies. Patients with mixed states, rapid cycling, and EEG abnormalities have been shown to respond favorably to valproate. Valproate is also being increasingly used in disorders with aggressive or agitated features, such as the behavioral disorders of dementia; yet, few studies have documented the utility of valproate in geriatric patients. The need to document safe and effective pharmacologic agents to treat geriatric mood and behavioral disorders continues to increase with the growing elderly population. We conducted a retrospective study of the use of valproate in patients consecutively hospitalized over a 5-year period on a psychiatric unit. Thirty-nine patients over age 60 were identified and then categorized into non-, partial, and full responders based on Clinical Global Impression ratings. Information on diagnosis, age, valproate dose and serum concentration, psychiatric symptoms, medical comorbidity, concurrent psychotropic medications, and side effects was collected. Results suggest that responders to valproate (full or partial) over the age of 60 years were more likely to be female, younger, carry a diagnosis of bipolar disorder, and achieve higher serum valproate concentrations. Full responders had fewer psychotic symptoms but usually displayed manic symptoms. The date of this study suggests the need for controlled clinical trials to clarify the utility and clinical predictors of response to valproate in the geriatric population.

Study of the effect of a liquid nutrition supplement on the nutritional status of psycho-geriatric nursing home patients.

OBJECTIVES: To evaluate the acceptance of a multinutrient liquid nutrition supplement in psycho-geriatric nursing home patients and the effect on weight, plasma nutrients and activities of daily life. DESIGN: Double-blind, placebo-controlled 12-week intervention study. SETTING: Two nursing homes in Boxtel, The Netherlands. SUBJECTS: Forty-two (body mass index (BMI) <23 kg/m2 for men or <25 kg/m2 for women) psycho-geriatric nursing home patients aged 60 y or over. INTERVENTIONS: Provision with a complete micronutrient-enriched liquid nutrition supplement of 125 ml and 0.6 MJ (135 kcal) or placebo twice daily during daytime between main meals. Study parameters were assessed at 0, 6 and 12 weeks. MAIN OUTCOME FOR MEASURES: Weight, Barthel index of daily activities, several plasma values (albumin, C-reactive protein (CRP), homocysteine, thiamine, thiamine diphosphate (TDF), vitamin B6, vitamin B12, folic acid, vitamin D), bowel function. RESULTS: The supplement was well accepted. Thirty-five patients completed the intervention period (16 control group; 19 supplement group). Baseline daily nutrient intake was low. A statistically significant improvement was observed for body weight (difference between groups 2.2 kg, P=0.03), and homocysteine, vitamin B1, TDF, vitamin B6, vitamin B12, folate and vitamin D in the supplement group compared to the placebo group. No significant difference was observed in the Barthel index (mean difference -0.3+/-1.1 for both groups). No difference in occurrence of diarrhoea was observed. CONCLUSIONS: The study shows that nutritional supplementation is well accepted and can improve the nutritional status of psycho-geriatric nursing home patients. SPONSORSHIP: Numico Research BV.

Toward individualized evidence-based medicine: five "N of 1" trials of methylphenidate in geriatric patients.

OBJECTIVES: To investigate the efficacy of methylphenidate in depressed or apathetic geriatric patients. DESIGN: Five "N of 1" trials (individual cross-over, double-blinded, randomized trials). SETTING: Department of Geriatrics, University Medical Center, Nijmegen, and two nursing homes in Nijmegen, the Netherlands. PARTICIPANTS: Patients suffered from depression due to a general medical condition (n = 2); depression resistant to antidepressive drugs (n = 1), chronic apathy due to mild and moderate severe dementia (n = 2). INTERVENTION: Methylphenidate (5 mg bid) and placebo (both for two subsequent days) in 5 weeks of randomized treatment blocks. MEASUREMENTS: Montgomery Asberg Depression Rating Scale (MADRS), Apathy Evaluation Scale (AES)-clinician, the AES-informant, Barthel index and a semiquantitative checklist of adverse effects. RESULTS: Among the three depressed patients, two showed significant improvement on the MADRS (P = .089 and P = .001; alpha = 0.10), one patient's apathy showed significant improvement on AES-clinician and -informant (P = .077 and P = .086). One apathetic patient's trial was stopped because AES could not be completed. None of the patients showed significant changes in the Barthel index. No side effects developed. CONCLUSION: "N of 1" trials are useful in evaluating efficacy of methylphenidate in depressed or apathetic geriatric patients. Single-patient trials can be a useful tool in pharmacotherapeutic decision-making in frail older subjects.

Developing a geriatric business plan for an academic medical center.

Leaders of geriatric programs at academic health centers (AHCs) face several challenges in seeking support for clinical program development. These challenges relate to how revenues from Medicare activities flow within AHCs. Typically, clinical departments such as the Department of Medicine see a very small proportion of total AHC Medicare revenue and frequently experience losses on their Medicare activities. In contrast, hospitals in AHCs see the bulk of the revenues and typically experience substantial profits. This article examines this situation in some detail, with specific examples from AHCs with which the author has consulted.The unique effect of Medicare revenue on AHCs requires the geriatric leader to identify who gains and who loses from Medicare activity within his or her AHC and to seek support for geriatric programs based on that analysis.

Prophylactic anticoagulation for venous thromboembolic disease in geriatric patients.

Venous thromboembolic disease (VTED) occurs commonly in geriatric medical patients, causing significant morbidity and mortality. Although VTED is preventable, prophylactic anticoagulation is underused. Awareness of the clinical risk factors that contribute to VTED in the elderly is essential for identifying candidates for prophylaxis. Iatrogenic risk factors include venous catheterization, transvenous pacemaker placement, hormone replacement therapy, and immobilization or prolonged bed rest. Medical conditions associated with increased risk include a previous episode of VTED, myocardial infarction, heart failure, severe lung disease, cancer, and neurological conditions associated with paresis. Obstacles to the widespread usage of VTED prophylaxis in geriatric medical patients include the clinically silent nature of VTED, underestimation of the risk and clinical effect of VTED in this population, and concerns about the cost and safety of anticoagulant therapy in this population. Clinical practice guidelines devised specifically for geriatric medical patients facilitate rational use of thromboprophylaxis in this population. The safety, efficacy, cost-effectiveness, and convenience of low-molecular-weight heparins for thromboprophylaxis are reflected in their increasing prominence in clinical practice guidelines and clinical use.

Patient preference and gait efficiency in a geriatric population with transfemoral amputation using a free-swinging versus a locked prosthetic knee joint.

OBJECTIVE: To investigate patient preference, walking speed, and prosthetic use in a geriatric population with transfemoral amputation using a free-swinging prosthetic knee or a locked knee joint. DESIGN: Before-after trial. SETTING: Ambulatory patients at an amputee rehabilitation facility. PARTICIPANTS: A convenience sample of 14 geriatric individuals with a unilateral dysvascular transfemoral amputation (age range, 61-80y), who were using a prosthesis with a free-swinging knee in the community, 3 months after discharge from an amputee rehabilitation program. INTERVENTION: Change from a free-swinging knee to a locked knee. MAIN OUTCOME MEASURES: Patient preference, distance walked in 2 minutes, and prosthetic use as measured by the Houghton Scale. RESULTS: Eleven of 14 participants preferred the locked knee. Irrespective of preference, the mean 2-minute walk distance was 44.9 +/- 28.9m with the free-swinging knee and 54.4 +/- 35m with the locked knee (P = .001). Prosthetic use was greater with the locked knee (7.8 +/- 2.2) than with the free-swinging knee (6.6 +/- 2.5) (P = .01). CONCLUSIONS: Most geriatric participants with transfemoral amputation preferred locked knees and walked faster and used their prostheses more when using a locked knee prosthesis.

Trends in rehabilitation after amputation for geriatric patients with vascular disease: implications for future health resource allocation.

OBJECTIVE: To assess the effect of demographic changes on rehabilitation of geriatric patients after amputation and the implications for future health resource allocation. DESIGN: Population-based study. SETTING: Olmsted County, MN. PARTICIPANTS: Residents over the age of 65 years who had a major lower-extremity amputation because of peripheral arterial disease between 1956 and 1995. Patients who had amputations between 1956 and 1973 (earlier cohort) were compared with those who had amputations between 1974 and 1995 (later cohort). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Demographic and clinical features, total number of amputations, amputation rates, and rate of successful prosthetic fitting over time. RESULTS: Of 292 patients, 93 had amputations between 1956 and 1973 and 199 between 1974 and 1995. Amputation rates declined after 1985, but the total number of amputations was unchanged. Patients in the later cohort were more likely to have a below-knee amputation (P<.001) and cerebrovascular disease (P=.008) and to be discharged to a nursing home (P<.001). There was no significant difference in median age at amputation, survival, or rates of successful prosthetic fitting over time. CONCLUSION: Although amputation rates have declined, the total number of amputations has increased. The rate of successful prosthetic fitting in the geriatric population has not changed significantly over 40 years. Amputations in the geriatric population in the United States will probably double from 28,000 to 58,000 per year by 2030, requiring considerable resources.

The reproducibility of a new dietary record routine in geriatric patients.

BACKGROUND AND AIM: Malnutrition in nursing home residents is an important clinical and public health problem. Knowledge is lacking about the reproducibility of dietary recording in geriatric patients. Few studies have described water intake in this age group. The aim of this study was to test the reproducibility of a 7-day dietary record routine in a clinical setting. METHODS: The dietary intake of 81 geriatric patients was recorded for two discrete periods of 7 consecutive days by the ward staff. The dietary record routine, which assessed both food and fluid intake, was based on standardized portion sizes and household measurements. RESULTS: The mean daily energy intake during the first period was 7.07 MJ and 6.84 MJ during the second period, with a mean difference of 4%. Corresponding values and the mean difference for water intake from food and beverages were 1781 g, 1702 g and 4% respectively. Age, gender, diagnosis, length of stay, diets or ADL function did not influence the results. The correlation coefficient for fluid intake between the periods was 0.84 for women and 0.72 for men. CONCLUSION: The 7-day dietary record routine seems to have a good reproducibility in assessing the intake of energy and fluids in geriatric patients.

[Dementia disorders, behavior problems and the care of clients in geriatric day-care compared to residents in homes for the elderly: a cross-sectional study in eight communities in Baden].

AIM: The study aims to compare clients using institutions of geriatric day-care to residents in homes for the elderly with regard to functional impairment, dementia disorders, behavior problems and the care situation. METHODS: A cross-sectional study of 17 geriatric day-care facilities in eight towns and cities in Baden examined the data for all 257 clients who received care on a given reference date. These clients were compared to a reference population drawn from all residents (N = 1,387) of 15 randomly selected residential and nursing homes in the city of Mannheim, whereby identical assessment procedures were used by qualified nursing staff. RESULTS: The average age of subjects in both groups was around 80 years, over three-fourths of whom were women. Home residents were more limited than the clients of geriatric day-care facilities with regard to their activities of daily living, above all with regard to their mobility. The percentage of moderate to severe dementia disorders at 58.6 % was equally high in both groups. In addition, symptoms of depression and behavior problems were observed among a substantial number of the day-care clients. While the inpatient sector places greater emphasis on basic care and treatment, day-care institutions focus primarily on measures of social therapy. CONCLUSIONS: The high percentage of demented yet still mobile clients in day-care facilities indicates the particular importance of this target group when it comes to providing at least partial stress relief for family care-givers.

Prevalence and haemopoietic effects of low serum vitamin B12 levels in geriatric medical patients.

The clinical significance of low serum vitamin B12 levels in elderly people is controversial. We aimed to document the prevalence of a low serum vitamin B12 (< 175 pmol/l) in patients referred to a geriatric medical unit, and to determine whether haemopoiesis is commonly affected in elderly patients with low serum vitamin B12. We studied prospectively 472 consecutive referrals to a geriatric medical unit; fifty-six (13%) had a low serum vitamin B12 level, of whom nineteen (34%) of the fifty-six also had evidence of Fe deficiency (serum ferritin < 45 ng/ml). Low vitamin B12 was associated with a raised mean erythrocyte volume (MCV; mean 96.0 (SD 6.7) fl), compared with a control group (91.7 (SD 6.0) fl; P = 0.001). However, only thirteen (23%) of the fifty-six patients with a low vitamin B12 had an MCV > or = 100 fl. Mean haemoglobin (Hb) levels were not significantly reduced in those with a low vitamin B12. In a subsequent study the haematological response to intramuscular hydroxocobalamin was examined in thirty-four patients with a low serum vitamin B12. Treatment resulted in a significant fall in MCV and rise in Hb; these effects could be detected both in those patients with an initially normal full blood count (change in MCV -1.2 (SD 1.2); Hb +0.5 (SD 0.6); P < 0.01) and in those with macrocytosis and/or anaemia (-9.1 (SD 11.8); +0.8 (SD 1.2); P < 0.05). A low serum vitamin B12 is common in geriatric medical patients. This is usually associated with an upset in erythropoiesis, although the abnormalities are often subtle and may not be apparent on inspection of the full blood count. Elderly patients with serum vitamin B12 < 175 pmol/l should be assumed to have vitamin deficiency even if their full blood count is normal.
