Functional Decline in COVID-19 Older Survivors Compared to Other Pneumonia Patients, a Case Control Study.

OBJECTIVES: Among patients over 75 years, little is known about functional decline due to COVID-19. The aim of this study was to explore this functional decline, compare to other infectious pneumonia. DESIGN AND SETTING: This case-control study included all COVID-19 patients hospitalized from March to December 2020 in Acute Geriatric Ward in Nantes University Hospital matched 1/1 with patients with pneumonia hospitalized in geriatric department between March 2017 and March 2019 (controls) on sex, age. Functional decline was assessed at 3 month follow up as it is routinely done after hospitalization in geriatric ward. We performed multivariable analyses to compare clinical outcomes between patients with COVID-19 vs controls. RESULTS: 132 pairs were matched on age (mean: 87 y-o), and sex (61% of women). In multivariable logistic regression analysis, there were no statistical significant association between COVID-19 infection and functional decline (OR=0.89 p=0.72). A statistical significant association was found between functional decline and Charlson comorbidity index (OR=1.17, p=0.039); prior fall (OR=2.08, p=0.012); malnutrition (OR=1.97, p=0.018); length of hospital stay (OR=1.05, p=0.002) and preadmission ADL(OR=1.25, p=0.049). CONCLUSION: COVID-19 does not seem to be responsible for a more frequent or severe functional decline than other infectious pneumonia in older and comorbid population after 3 month follow up. In this population, pneumonia is associated with functional decline in almost 1 in 2 cases. The individual preadmission frailty seems to be a more important predictor of functional decline, encouraging multidimensional care management for this population.

[Cancer-screening for older patients]. / Dépistage des cancers chez le sujet âgé.

Cancer-screening programmes are public health action for a target population. It guarantees an equal access to screening throughout the country with a high level of quality for every person of the target population. Given the heterogeneity of older subjects and the variability of the expected benefits of cancer-screening programmes, this collective public health action may not have a collective benefit for the population. However, for older person with a life expectancy of five years or more, it would be possible to propose an individualized cancer-screening decision. This cancer-screening approach must respect the ethical principles of avoiding harm and supporting autonomy. In addition, it is important to consider the goals and values of patients to take an individualized decision. Patients with the same profile may not take the same decision of individualized cancer screening.

Association between dementia and reduced walking ability and 30-day mortality in patients with extended-spectrum beta-lactamase-producing Escherichia coli bacteremia.

Previous studies have shown controversial results of factors associated with short-term mortality in patients with extended-spectrum beta-lactamase (ESBL)-producing E. coli bacteremia and no research has investigated the impact of the geriatric assessment criteria on short-term mortality. Our objective was to determine whether dementia and walking ability are associated with 30-day mortality in patients with ESBL-producing E. coli bacteremia. All blood bottle cultures, analyzed from January 2008 to April 2015, in the Bacteriology Department of a 2,600-bed, university-affiliated center, Nantes, France, were retrospectively extracted. Factors associated with short-term mortality in patients with ESBL-producing E. coli bacteremia: 140 patients with an ESBL-producing E. coli bloodstream infection were included; 22 (15.7%) patients died within 30 days following the first positive blood bottle culture of ESBL-producing E.coli. In multivariate analysis, a reduced ability to walk (OR = 0.30; p = 0.021), presence of dementia (OR = 54.51; p = 0.040), a high Sepsis-related Organ Failure Assessment (SOFA) score (OR = 1.69; p < 0.001), presence of neutropenia (OR = 12.94; p = 0.049), and presence of a urinary tract infection (OR = 0.07; p = 0.036), were associated with 30-day mortality. Our findings provide new data showing an independent association between 30-day mortality with dementia and reduced walking ability, in patients with ESBL-producing E. coli bacteremia. These criteria should be considered in the therapeutic management of patients with ESBL-producing E. coli bacteremia.

[Oral anticoagulants adherence in elderly patients treated for atrial fibrillation in the era of direct oral anticoagulants]. / Observance du traitement anticoagulant oral chez le sujet âgé à l'ère des anticoagulants oraux directs.

BACKGROUND: The aim of this study was to determine the level of adherence to oral anticoagulants in the population of elderly patients treated for a non-valvular atrial fibrillation (AF) in the era of direct oral anticoagulants. PATIENTS AND METHOD: This transversal study used Morisky scale to assess adherence to oral anticoagulants. We also collected patients' reviews about the treatment and factors explaining a poor adherence. RESULTS: Between January and June 2015, 64 patients were included in Loire Atlantique. Average age was 77.8 years, CHA2DS2-VASc score was 4.06 and treatment (vitamin K antagonists [VKAs] in 78% patients) was prescribed since 4.3 years. According to Morisky scale, 84.4% of patients had a good adherence. There was 88% of good adherence with AVK versus 71% with direct oral anticoagulant, there was no statistically significant difference. The prescriber and the knowledge of anticoagulant treatment role seemed to be determinant factors. CONCLUSIONS: The level of adherence for oral anticoagulant appears higher than in most published studies. Diversification of therapeutic options could constitute an aid to personalize the prescription in order to improve it.

Predictors of Health-Related Quality of Life Decline after Transcatheter Aortic Valve Replacement in Older Patients with Severe Aortic Stenosis.

BACKGROUND: Transcatheter aortic-valve implantation (TAVI) has been shown to improve survival and quality of life in patients with severe aortic stenosis. However, one-third of patients have poor outcome as death, functional decline or quality of life (QoL) decline. The aim of this study was to determine cardiac and geriatric predictors of physical and mental QoL decline 6 months after a TAVI procedure in patients aged 75 and older. METHODS: Between January 2013 and June 2014, we did a prospective and multicenter study including patients ≥ 75 years old referred for TAVI. The primary outcome was the measure of QoL, assessed by the Short Form 36 survey (SF-36), before and 6 months after the intervention. Association between QoL decline and baseline characteristics including cardiac and geriatric factors was analysed by logistic regression models. RESULTS: Mean age of the 150 patients studied was 83.7 years old and 56% were men. The primary end point, mean SF-36 physical summary score, significantly improved between baseline and 6-month (33.6 vs. 36.4, p=0.003) whereas mental component score significantly decreased (48.2 vs. 36.4, p-value<0.001). However, patients with presence of depressive symptoms before the intervention had mental QoL improvement at six months (OR 0.04 [0.01-0.19], p-value<0.001) and no significant geriatric predictors were associated with physical QoL decline. CONCLUSION: The mental QoL significantly decreased and patients with preoperative depressive symptoms had mental QoL improvement at six months. Researches are needed to confirm that mental QoL of patients with depressive symptoms can be improved by TAVI.

[Place of azathioprine in the treatment of giant cell arteritis]. / Utilisation de l'azathioprine dans le traitement de l'artérite à cellules géantes.

OBJECTIVE: The aim of this bicentric retrospective study was to describe the use of azathioprine in giant cell arteritis, and to appreciate its corticosteroid-sparing effect in glucocorticoid-dependent patients or with severe glucocorticoid related side effects. METHODS: We retrospectively reviewed the medical records of patients diagnosed with giant cell arteritis between 2000 and 2011 in two departments of internal medicine. Only the patients treated with azathioprine were included in this study. Sociodemographic, clinical, biological, radiological and therapeutic data were collected by a standardized questionnaire. A comparative analysis of daily prednisone dose at the initiation and 1 year after the prescription of azathioprine was made. RESULTS: Of the 28 patients included, 21 responded to azathioprine. At 1 year of follow-up after the initiation of azathioprine, 18 patients (64%) were still in sustained response, asymptomatic, without increase in acute phase response laboratory markers, and with a daily dose of prednisone<10 mg. Three patients (11%) experienced a relapse during azathioprine treatment. Mean daily dose of prednisone were 25.4 mg at the time of initiation of azathioprine, and 4.7 mg at 1 year of treatment, suggesting a corticosteroid-sparing effect (P<0.001). Ten patients experienced azathioprine serious side effects, leading to discontinuation of treatment in seven cases. CONCLUSION: Azathioprine may be an alternative treatment for patients with giant cell arteritis requiring prolonged high dose glucocorticoid therapy or developing severe glucocorticoid related side effects. However, given the potential adverse effects of azathioprine, a close monitoring is necessary.

[Comprehensive geriatric assessment (CGA) in elderly with cancer: For whom?]. / Évaluation gériatrique en oncologie : pour quels patients ?

Scientific societies recommend the implementation of a comprehensive geriatric assessment (CGA) in cancer patients aged 70 and older. The EGA is an interdisciplinary multidimensional diagnostic process seeking to assess the frail older person in order to develop a coordinated plan of treatment and long-term follow-up. Identification of comorbidities and age-induced physiological changes that may increase the risk of anticancer treatment toxicities is essential to better assess the risk-benefit ratio in elderly cancer patients. The systematic implementation of a CGA for each patient is difficult to perform in daily practice. Therefore, it is recommended to screen vulnerable patients who will benefit from a complete CGA. Our work presents the vulnerability screening tools validated by at least two independent studies in a cancer elderly population setting. Among seven screening tools, the G8 and the VES13 are the most effective, and have been validated specifically in older population with cancer. The G8 is recommended by scientific societies and the French National Cancer Institute (INCa) because of its easy implementation in daily clinical practice, its high sensitivity and fair specificity. Although studies are underway to improve its performance, the G8 is currently the simplest tool to routinely identify older cancer patients who should have a complete assessment in geriatric oncology.

Risk of Unplanned Emergency Department Readmission after an Acute-Care Hospital Discharge among Geriatric Inpatients: Results from the Geriatric EDEN Cohort Study.

OBJECTIVES: The study aims 1) to examine whether items of the brief geriatric assessment (BGA) or their combinations predicted the risk of unplanned emergency department readmission after an acute care hospital discharge among geriatric inpatients, and 2) to determine whether BGA could be used as a prognostic tool for unplanned emergency department readmission. METHODS: A total of 312 older patients (mean age, 84.6 ± 5.4 years; 64.1% female) hospitalized in acute care wards after an emergency department visit were recruited in this observational prospective cohort study and separated into 2 groups based on the occurrence or not of an unplanned emergency department readmission during a 12-month follow-up period after their hospital discharge. A 6-item BGA was performed at emergency department admission before the discharge to acute care wards. Information on incident unplanned emergency department readmission was prospectively collected by phone call and by consulting the hospital registry. Several combinations of items of BGA identifying three levels of risk of unplanned emergency department readmission (i.e., low risk, intermediate risk and high risk) were examined. RESULTS: The unplanned emergency department readmission was more frequently associated with a temporal disorientation (P=0.004). Area under receiver operating characteristic curves of unplanned emergency department readmission based on BGA items and their combinations ranged from 0.53 to 0.61. The best predictor of unplanned emergency department readmission was the temporal disorientation (hazard ratio>1.65, P<0.035), which defined the high-risk group. Inpatients classified in high-risk group of unplanned emergency department readmission were more frequently readmitted to emergency department than those in intermediate- and low-risk groups (P log Rank <0.004). Prognostic values for unplanned emergency department readmission of items and their combinations were poor with sensitivity below 67%, specificity ranging from 36.4 to 53.7, and positive likelihood ratio below 1.4. CONCLUSIONS: The items of BGA and their combinations were significant risk factors for unplanned emergency department readmission, but their prognostic value was poor.

General practitioners adherence to recommendations from geriatric assessments made during teleconsultations for the elderly living in nursing homes.

OBJECTIVES: To determine the factors associated with general practitioners adherence to recommendations from geriatric assessments made during teleconsultations for the elderly living in nursing homes. STUDY DESIGN: Prospective cohort study in three nursing homes in Vendee, France, with access to teleconsultations from Challans Hospital. Teleconsultations with geriatric assessment for which recommendations were made by a geriatrician (n=69). MAIN OUTCOME MEASUREMENTS: Participants were separated into two groups based on the evidence of general practitioners adherence to recommendations 30 days after teleconsultation. Their adherence has been defined by the application by themselves supporting the elderly of prescription or organization of all recommendations made by the geriatrician during the teleconsultation. The type of recommendations was pharmacological and non-pharmacological treatments, and expert medical advice. The recorded data included the main reason of teleconsultation's request, age, sex, dementia diagnosis, multimorbidities scale, body mass index, Activities of Daily Living Scale, 4-items Geriatric Depression Scale, existence of a fall, and the Neuropsychiatric Inventory. Logistic regressions were performed to examine the factors associated with general practitioners adherence to recommendations from the geriatric assessment. RESULTS: General practitioners adherence to recommendations was made for 58 teleconsultations (86.3%). A fully adjusted logistic regression showed that general practitioners adherence to recommendations was associated with risk of depressive syndrome (OR=8.00, P=0.040) and expert medical advice's recommendations (OR=17.97, P=0.040). CONCLUSIONS: General practitioners adherence to recommendations from the geriatric assessment made during teleconsultations for elderly living in nursing homes is associated with the risk of depressive syndrome's existence and the expert medical advice recommendations.

Determinants in treatment decision-making in older patients with symptomatic severe aortic stenosis.

BACKGROUND: Three treatment options are available for patients with aortic stenosis: surgical aortic valve replacement (SAVR), transcatheter aortic valve implantation (TAVI) and medical treatment (MT). However, little is known about how Heart Team treatment decisions are made under routine conditions. The aim of this study was to identify the cardiac and geriatric components associated with treatment decision-making in older patients with symptomatic severe aortic stenosis. METHODS: Between 2011 and 2013, 337 consecutive patients ≥75 years old referred for pre-operative evaluation in Nantes University Hospital had a comprehensive cardiac and geriatric assessment. In this observational retrospective study, relationships between treatment decision-making and cardiac or geriatric components were evaluated through multivariable models. RESULTS: Surgical aortic valve replacement was proposed to 108 patients, TAVI to 131 and medical treatment to 98 patients. Mean age was 83±4 years and 51% were women. Geriatric components associated with treatment decision-making between SAVR vs. TAVI were age (p<0.001, OR=0.790), comorbidity score (p=0.027, OR=0.86), functional status (p<0.001, OR=1.46), and gait speed (p<0.001, OR=0.23). Cardiac components associated with decision-making between SAVR vs. TAVI were history of previous cardiac surgery (p<0.001, OR=0.09), left ventricular ejection fraction <50% (p<0.001, OR=0.14), coronary artery disease requiring revascularization (p=0.019, OR=0.4). Between TAVI vs. medical treatment, only history of previous cardiac surgery and presence of another severe valve disease were significant. CONCLUSION: Comorbidities, functional status and physical performance, were significantly associated with the consensual treatment decision-making, independently of cardiac components in older patients with symptomatic severe aortic stenosis.

Do not resuscitate orders and aging: impact of multimorbidity on the decision-making process.

BACKGROUND: The "Do Not Resuscitate" orders (DNR) are defined as advance medical directives to withhold cardiopulmonary resuscitation during cardiac arrest. Age-related multimorbidity may influence the DNR decision-making process. Our objective was to perform a systematic review and meta-analysis of published data examining the relationship between DNR orders and multimorbidity in older patients. METHODS: A systematic Medline and Cochrane literature search limited to human studies published in English and French was conducted on August 2012, with no date limits, using the following Medical Subject Heading terms: "resuscitation orders" OR "do-not-resuscitate" combined with "aged, 80 and over" combined with "comorbidities" OR "chronic diseases". RESULTS: Of the 65 selected studies, 22 met the selection criteria for inclusion in the qualitative analysis. DNR orders were positively associated with multimorbidity in 21 studies (95%). The meta-analysis included 7 studies with a total of 27,707 participants and 5065 DNR orders. It confirmed that multimorbidity were associated with DNR orders (summary OR = 1.25 [95% CI: 1.19-1.33]). The relationship between DNR orders and multimorbidity differed according to the nature of morbidities; the summary OR for DNR orders was 1.15 (95% CI: 1.07-1.23) for cognitive impairment, OR=2.58 (95% CI: 2.08-3.20) for cancer, OR=1.07 (95% CI: 0.92-1.24) for heart diseases (i.e., coronary heart disease or congestive heart failure), and OR=1.97 (95% CI: 1.61-2.40) for stroke. CONCLUSIONS: This systematic review and meta-analysis showed that DNR orders are positively associated with multimorbidity, and especially with three morbidities, which are cognitive impairment, cancer and stroke.

Risk of in-hospital mortality following emergency department admission: results from the geriatric EDEN cohort study.

OBJECTIVE: To determine whether being admitted to emergency department (ED) for social disorders may predict a higher risk of in-hospital mortality among older inpatients. DESIGN: Prospective cohort study (mean follow-up: 9.1±10.0 days). SETTING: Angers University Hospital, France. PARTICIPANTS: Four hundred twenty-two inpatients (mean age 84.9±5.6years, 64.2% women). METHODS: At their admission to ED, inpatients aged 75 years and over received an assessment composed of 6 items: age, gender, number of drugs daily taken, history of falls during the past 6 months, usual place of life, and use of formal and/or informal home and social services. The reasons for admission to ED as well the diagnosis at the time of hospital discharge were separated into social and health disorders. The length of hospital stay was calculated in number of days using the hospital registry. Inpatients were separated into 2 groups based on the occurrence or not of death during the hospital stay. RESULTS: Older inpatients who died at hospital were more frequently institutionalized (P=0.034) and admitted to ED for social disorders (P=0.002) than those who did not. Multiple Cox regression model revealed that living in institution and social disorders as a reason for admission to ED were significantly associated with the occurrence of death at hospital (P=0.008 and P=0.036). Kaplan-Meier distributions of in-hospital mortality showed that home-living inpatients admitted to ED for social disorders died more and faster during hospitalization than those admitted for health disorders (P=0.016). CONCLUSION: Being admitted to ED for social disorders and living in institution predicted a higher risk of in-hospital mortality.

Physical training-related changes in gait variability while single and dual tasking in older adults: magnitude of gait variability at baseline matters.

OBJECTIVES: Few studies have examined the effects of physical training programs on gait variability while single and dual tasking, and they reported mixed results. The aim of this study was to compare the stride time variability while single and dual tasking before and after a physical training program developed to improve gait stability in French community-dwelling older adults. DESIGN: A prospective pre-post interventional cohort study. SETTING: The community-dwelling area of "Pays de la Loire", France. POPULATION: Forty-eight older adults (mean age ± standard deviation 72.2±8 years; 75% female). METHODS: Physical training program consisted in 12 sessions scheduled to attend physical exercises 1 time a week with total time duration of 3 months. Coefficient of variation (CoV) of stride time under three walking conditions (i.e., walking alone, walking while backward counting, and while performing a verbal fluency task) was determined while steady-state walking using the SMTEC® footswitches system before and after the physical training program. Participants were separated into two groups based on being or not in the highest tertile (i.e., worst performance with cutpoint >4.4%) of the CoV of stride time while walking alone. RESULTS: After physical training compared to before period, a significant decrease in CoV of stride time (i.e., better gait performance) while walking alone (2.8±2.8% versus 7±7.1%, P=0.001) but not while dual tasking (P=0.600 for counting backward and P=0.105 for verbal fluency task) was shown in participants who had highest (i.e., worst) gait variability at baseline. In addition, physical training modified the strategy of dual tasking in participants with highest gait variability at baseline compared to the other participants. Before training, a significant decrease in CoV of stride time (7±7.1% versus 4.9±4.6%, P=0.017) while counting backward was shown, but there was a significant increase after training (2.8±2.8% versus 5.4±5.8%, P=0.007). CONCLUSIONS: Physical training reduced gait variability while walking alone in participants with gait instability, and influenced their strategy for dual tasking. CLINICAL REHABILITATION IMPACT: Physical program training developed in the community to improve gait stability should included participants with high gait variability.

Promoting access to innovation for frail old persons. IAGG (International Association of Gerontology and Geriatrics), WHO (World Health Organization) and SFGG (Société Française de Gériatrie et de Gérontologie) Workshop--Athens January 20-21, 2012.

UNLABELLED: Frailty tends to be considered as a major risk for adverse outcomes in older persons, but some important aspects remain matter of debate. OBJECTIVES: The purpose of this paper is to present expert's positions on the main aspects of the frailty syndrome in the older persons. PARTICIPANTS: Workshop organized by International Association of Gerontology and Geriatrics (IAGG), World Health Organization (WHO) and Société Française de Gériatrie et de Gérontologie (SFGG). RESULTS: Frailty is widely recognized as an important risk factor for adverse health outcomes in older persons. This can be of particular value in evaluating non-disabled older persons with chronic diseases but today no operational definition has been established. Nutritional status, mobility, activity, strength, endurance, cognition, and mood have been proposed as markers of frailty. Another approach calculates a multidimensional score ranging from "very fit" to "severely frail", but it is difficult to apply into the medical practice. Frailty appears to be secondary to multiple conditions using multiple pathways leading to a vulnerability to a stressor. Biological (inflammation, loss of hormones), clinical (sarcopenia, osteoporosis etc.), as well as social factors (isolation, financial situation) are involved in the vulnerability process. In clinical practice, detection of frailty is of major interest in oncology because of the high prevalence of cancer in older persons and the bad tolerance of the drug therapies. Presence of frailty should also be taken into account in the definition of the cardiovascular risks in the older population. The experts of the workshop have listed the points reached an agreement and those must to be a priority for improving understanding and use of frailty syndrome in practice. CONCLUSION: Frailty in older adults is a syndrome corresponding to a vulnerability to a stressor. Diagnostic tools have been developed but none can integrate at the same time the large spectrum of factors and the simplicity asked by the clinical practice. An agreement with an international common definition is necessary to develop screening and to reduce the morbidity in older persons.

Who is at risk of long hospital stay among patients admitted to geriatric acute care unit? Results from a prospective cohort study.

OBJECTIVE: (1) To confirm that vitamin D deficiency, defined as serum 25-hydroxyvitamin D (25OHD) concentration < 25 nmol/L, was associated with long length-of-stay (LOS) among older inpatients admitted to geriatric acute care unit; and (2) to examine which combination of risk factors of longer LOS including vitamin D deficiency best predicted longer LOS. STUDY DESIGN AND SETTING: Based on a prospective cohort study with a 25-day follow-up on average, 531 consecutive older inpatients (mean age 85.0±7.2 years, 59.1% women) admitted to the geriatric acute care unit of Angers University Hospital, France, were included. RESULTS: Linear regression models showed that male gender (P<0.025), delirium (P<0.015) and vitamin D deficiency (P<0.001) were independently associated with a longer LOS. The highest risk of a longer LOS was shown while combining vitamin D deficiency with male gender (Odds ratio (OR)=3.70 with P< 0.001). The risk increased significantly while delirium was associated with these two baseline characteristics (OR=4.76 with P=0.001). Kaplan-Meier distributions of discharge differed significantly between participants who had or not the combination of the 3 criteria (P<0.007). CONCLUSIONS: Vitamin D deficiency, delirium and male gender were significant risk factors for a longer LOS in the studied sample of older inpatients.

Association of depressive symptoms with recurrent falls: a cross-sectional elderly population based study and a systematic review.

BACKGROUND: Screening of depressive symptoms is recommended in recurrent fallers. Compared to the 30-item and 15-item Geriatric Depression Scales (GDS), the 4-item GDS is easier to administer and quicker to perform. The association between abnormal 4-item GDS score and recurrent falls has not yet been examined. In addition, while depressive symptoms-related gait instability is well known, the association with recurrent falls has been few studied. OBJECTIVE: 1) To examine the association between abnormal 4-item GDS score and recurrent falls in community-dwelling older adults using original data from health examination centers (HEC) of French health insurance of Lyon, and 2) to perform a systematic review of studies that examined the association of depressive symptoms with recurrent falls among older adults. METHODS: Firstly, based on a cross-sectional design, 2,594 community-dwellers (mean age 72.1±5.4years; 49.8% women) were recruited in HEC of Lyon, France. The 4-item GDS score (abnormal if score≥1) and recurrent falls (i.e., 2 or more falls in the past year) were used as main outcomes. Secondly, a systematic English and French Medline literature search was conducted on May 28, 2012 with no limit of date using the following Medical Subject Heading (MeSH) terms "Aged OR aged, 80 and over", "Accidental falls", "Depressive disorder" and "Reccurence". The search also included the reference lists of the retrieved articles. RESULTS: A total of 19.0% (n=494) participants were recurrent fallers in the cross-sectional study. Abnormal 4-item GDS score was more prevalent among recurrent fallers compared to non-recurrent fallers (44.7% versus 25.0%, with P<0.001), and was significantly associated with recurrent falls (Odd ratio (OR)=1.82 with P<0.001 for full model; OR=1.86 with P<0.001 for stepwise backward model). In addition to the current study, the systematic review found only four other studies on this topic, three of them examining the association of depressive symptoms with recurrent falls using 30-item or 15-item GDS. All studies showed a significant association of depressive symptoms with recurrent falls. CONCLUSIONS: The current cross-sectional study shows an association between abnormal 4-item GDS score and recurrent falls. This association of depressive symptoms with recurrent falls was confirmed by the systematic review. Based on these results, we suggest that recurrent falls risk assessment should involve a systematic screening of depressive symptoms using the 4-item GDS.

Derivation and validation of a Short Form of the Mini-Mental State Examination for the screening of dementia in older adults with a memory complaint.

BACKGROUND AND PURPOSE: To validate a Short Form of the Mini-Mental State Examination (SMMSE) as a screening test for dementia in older ambulatory individuals followed in a memory clinic for a memory complaint. METHODS: A total of 202 cognitively healthy individuals, 100 individuals with a mild cognitive impairment and 304 demented individuals sent for a memory complaint by their primary care physician to a memory clinic were prospectively included in this cross-sectional study. They were randomized into derivation (n = 303) and validation (n = 303) groups. The SMMSE score was built from six memory items of MMSE, with a score ranging from 0 to 6 (i.e. best performance). RESULTS: The receiver operating characteristic curve showed an area under the curve of 0.98 for the derivation group and 0.97 for the validation group without differences between curves (P = 0.254). The cut-off between the sensitivity and the specificity of the SMMSE score for clinically diagnosed dementia was ≤4. The performance of the SMMSE for the diagnosis of dementia was high in the derivation and validation groups: sensitivity at 93.1% and 93.8%, specificity at 93.8% and 90.5%, positive predictive value at 94.3% and 90.1%, negative predictive value at 92.5% and 94.0%, likelihood ratio of positive test at 14.9 and 9.8 and of negative test at 0.07 and 0.07, respectively. CONCLUSIONS: The Short Form of the Mini-Mental State Examination was a good screening test for dementia in older individuals followed in a memory clinic for a memory complaint. The next step should be the confirmation of its discriminative value in older primary care patients.

Treatment-limiting decisions, comorbidities, and mortality in the emergency departments: a cross-sectional elderly population-based study.

BACKGROUND: Older adults experience a higher risk of death in the emergency departments (EDs), in part, as a result of their comorbidities. A treatment-limiting decision is often reported for older adults who die in the EDs. The Charlson Comorbidity Index (CCI) is a validated method for the scoring of comorbidities. Whether an association between the CCI and treatment-limiting decisions exists remains unknown. OBJECTIVE: To determine whether the CCI was associated with the treatment-limiting decisions made for older patients who die in the EDs. METHODS: A total of 2,095 patients ≥65 years old who died in the EDs in France and Belgium were prospectively included between 2004 and 2005. The recorded data included: 1) the CCI score; 2) patient age; 3) gender; 4) living in senior housing facilities; 5) hospitalizations occurring in the previous year; 6) presence of functional limitations (according to the Knaus classification); 7) chronic diseases; and 8) presence of organ failure(s). A treatment-limiting decision was defined as a predetermined choice not to implement therapies that would otherwise be required to sustain life. RESULTS: A treatment-limiting decision was identified in 993 (47%) patients. Fully-adjusted logistic regression model showed that a CCI ≥ 5 (OR=25.56 with P=0.037), age ≥85years (OR=20.33 with P<0.001), living in an institution (OR=0.15 with P=0.017), hematologic (OR=6.92 with P=0.020) and respiratory disease (OR=0.17 with P=0.046), and neurologic causes (OR=0.20 with P=0.010) of organ failure were significantly associated with treatment-limiting decisions. CONCLUSION: An elevated CCI score (≥5) was associated with a treatment-limiting decision in elderly patients evaluated in the EDs. Further research is needed to corroborate this finding.

Cost and resource utilization for prevention and treatment of foot lesions in a diabetic foot clinic in Belgium.

This prospective observational study was carried out to assess the annual preventive and curative treatment costs for diabetic foot problems. Measures of resource use over the 1-year study period were taken for 151 patients whose lesions covered the entire Wagner classification. Treatment was provided under the current protocols of a multidisciplinary team. The 1993 market prices for health services were used to convert units of health service utilization to expenditures by the social insurance system and the patients. The severity of the foot problems determined the medical cost. Preventive care (47 cases), represented an average cost per case of US$ 880 (1US$ 1993=BEF 30.65).
