Functional status and mortality at month and year in nonagenarians hospitalized due to acute medical illness

OBJECTIVES

To analyze risk factors associated with short and long-term mortality in nonagenarians hospitalized due to acute medical conditions.

DESIGN, SETTING, AND PARTICIPANTS

Prospective study of all patients aged 90 years or older admitted in a geriatric unit during 2009 due to medical acute illness. Baseline variables were collected at admission (sex, cause of admission, Charlson index, serum albumin, functional, and mental status), functional loss at admission (as the difference between Barthel index(BI) 2 weeks before admission and BI at admission), and functional loss at discharge(as the difference between BI 2 weeks before admission and BI at discharge). The association of these variables with mortality at 1 month and 1 year after admission was analyzed by multivariate Cox regression analysis.

RESULTS

Out of all patients admitted, 434 (33%) were 90 years old or older and 76.3% were female. Mortality at 1 month and 1 year after admission was 19% and 57%, respectively. In the month mortality multivariate analysis, being older (HR, 1.11; 95% CI=1.02 to 1.20), a previous Barthel index less than 40 points (HR, 5.87; 95% CI=1.16 to 29.67), and functional loss at admission (HR; 1.13; 95% CI=1.03 to 1.25) were independent risk factors. When patients that died 1 month after admission were excluded, the presence of hypoalbuminemia <3g/dl (HR, 2.70; 95% CI=1.69 to 4.32) and functional loss at discharge (HR-1.08, 95% CI=1.03 to 1.14) were the factors associated with 1 year mortality.

CONCLUSIONS

In nonagenarians, functional impairment is the most important risk factor associated with short and long-term mortality after hospitalization due to acute medical illness.

[Efficiency of acute geriatric units: a meta-analysis of controlled studies]

OBJECTIVE

After analysing the effectiveness in the reduction in the incidence of functional impairment and a higher probability of returning home between elderly patients hospitalised due to an acute medical illness cared for in acute geriatric units (AGU) compared to conventional care units, we propose to assess the efficiency of this care.

MATERIAL AND METHODS

A systematic review and meta-analysis was made of controlled studies (randomised, no randomised and case-control) that compared care in UGA with care in conventional hospital units of patients of 65 years and over with an acute medical illness. Studies on administrative data bases, those that evaluated care of a single disease, and those that assessed units with care in the acute and sub-acute phase were excluded. A literature review was performed on articles published up to 31st of August 2008 in Medline, Embase, Cochrane Library, and references of systematic reviews and reviewed articles. The selection of the studies and the extraction of data on the hospital stay and care costs was made independently by two different researchers.

RESULTS

A total of 11 studies were included, of which 5 were randomised, 4 were non-randomised, and 2 case control, all of them providing data on hospital stay, with 7 of them providing data on hospital costs (4 clinical trials, 2 non-randomised and 1 case-control). The overall analysis of all the studies showed that those admitted to UGA had a statistically significant reduction in hospital length of stay compared to the elderly hospitalised in conventional units (mean difference -1.01 days; 95% CI, -1.66 to -0.36) and hospital care costs (mean difference of -330 US dollars; 95% CI, -540 to -120).

CONCLUSIONS

Care in AGU is more efficient than that provided in conventional units, since, as well as achieving a reduction in the incidence of functional impairment at discharge and increasing the probability of returning home, they reduce mean hospital stay and the hospital care costs.

Effectiveness of acute geriatric units on functional decline, living at home, and case fatality among older patients admitted to hospital for acute medical disorders: meta-analysis

OBJECTIVE

To assess the effectiveness of acute geriatric units compared with conventional care units in adults aged 65 or more admitted to hospital for acute medical disorders.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Medline, Embase, and the Cochrane Library up to 31 August 2008, and references from published literature. Review methods Randomised trials, non-randomised trials, and case-control studies were included. Exclusions were studies based on administrative databases, those that assessed care for a single disorder, those that evaluated acute and subacute care units, and those in which patients were admitted to the acute geriatric unit after three or more days of being admitted to hospital. Two investigators independently selected the studies and extracted the data.

RESULTS

11 studies were included of which five were randomised trials, four non-randomised trials, and two case-control studies. The randomised trials showed that compared with older people admitted to conventional care units those admitted to acute geriatric units had a lower risk of functional decline at discharge (combined odds ratio 0.82, 95% confidence interval 0.68 to 0.99) and were more likely to live at home after discharge (1.30, 1.11 to 1.52), with no differences in case fatality (0.83, 0.60 to 1.14). The global analysis of all studies, including non-randomised trials, showed similar results.

CONCLUSIONS

Care of people aged 65 or more with acute medical disorders in acute geriatric units produces a functional benefit compared with conventional hospital care, and increases the likelihood of living at home after discharge.

Recovery of functional impairment after acute illness and mortality: one-year follow-up study

BACKGROUND

Functional status in older people is a dynamic situation, which makes it necessary to evaluate functional capacity at different times to determinate their prognostic value.

OBJECTIVE

To examine the association between functional status (baseline and change after acute illness) and mortality and functional changes at 1 year.

METHODS

Hospital-based prospective longitudinal cohort study of all patients over 65 years old, admitted for multidisciplinary treatment of functional impairment after acute illness in a medium-stay unit (post-acute geriatric unit) of a teaching hospital ascribed to the Spanish National Health Service from Spain during 15 consecutive months. Functional status (Barthel Index, BI) was assessed prior to the acute illness, at admission in a post-acute unit, at discharge and 1 year later. At admission, other variables were collected: sociodemographic, main diagnostic for hospitalization (stroke, orthopedic process, or deconditioning), serum albumin, comorbidity (Charlson Index), cognitive status (Pfeiffer s Short Portable Mental Status Questionnaire). In order to analyze mortality 1 year after discharge, a Cox regression analysis was performed.

RESULTS

Three hundred and sixty-nine patients constituted the study population, mean age was 80.74 years (SD 7.4), 66.6% were female and 1 year after discharge mortality was 20%. In the multivariate analysis, variables associated with a higher 1-year mortality were age (HR 1.06; 95% CI = 1.00-1.07) male gender (HR 2.11; 95% CI = 1.26-3.55), worse prior functional status (HR 0.98; 95% CI = 0.96-0.99), and higher functional loss in BI at admission (HR 1.02; 95% CI = 1.00-1.04). On the other hand, a greater functional gain in BI at discharge was associated with a lower 1-year mortality (HR 0.98; 95% CI = 0.96-0.99).

CONCLUSIONS

The main functional gain obtained after treatment in a multidisciplinary post-acute geriatric unit is independently associated with a reduction in long-term mortality. In addition to baseline functional status and after acute illness, the subsequent potential recovery is very important to predict poor long-term outcomes.

[Prognostic factors of functional recovery in very elderly stroke patients. A one-year follow-up study]

INTRODUCTION

Although an advanced age is a factor associated to a poorer functional prognosis following a stroke, the capacity for recovery can be determined by other intercurrent clinical, functional and mental factors.

AIM

To evaluate the factors that determine the functional prognosis on discharge of very elderly patients who were admitted to hospital for their functional recovery after suffering a stroke.

PATIENTS AND METHODS

We conducted a longitudinal observational study of 168 patients over 65 years of age, who were hospitalised consecutively over a 15-month period. On admission, data concerning a number of clinical, neurological, functional and mental variables were collected. On being discharged from hospital their functional situation (Barthel index) and institutionalisation were evaluated.

RESULTS

The 48 patients aged 85 and above presented a lower degree of overall and relative functional recovery on discharge from hospital. Nevertheless, 52% had gained more than 20 points on the Barthel index on being discharged with respect to their score when they were admitted; on discharge 44% had recovered over 50% of the functional loss they had suffered following the stroke. On including the other basal variables in a logistic regression analysis, a very advanced age was associated in an independent manner to a greater risk of being institutionalised, but not to a poorer functional prognosis at discharge. Severe functional impairment on admission and post-stroke depression were the factors that were independently associated to moderate-severe disability on admission; in addition, the more severe the neurological consequences were, the lower the level of functional recovery was.

CONCLUSIONS

The capacity for functional recovery in very elderly stroke patients is mainly determined by the degree of functional and neurological repercussion. The functional prognosis should be individualised according to these factors, regardless of the age.

[Unilateral apraxia of eyelid closure in ischemic stroke: role of the right hemisphere in the emotional gesture communication]

INTRODUCTION

Apraxia of eyelid closure (AEC) is an infrequent disorder that is characterised by the inability to close the eyelids on command, although spontaneous blinking and reflex shutting of the eyes is preserved. Very few cases of unilateral AEC have been reported and no long-term follow-ups have been carried out. We report the case of a patient with unilateral AEC that was followed up over a 3-year period and also discuss the role played by the right hemisphere in this disorder. CASE REPORT" We examined the case of a 67-year-old right-handed male who was admitted because of a parietotemporal infarction with extension into the subcortex. A few days after the stroke the patient reported the inability to close his left eye on command, although he was still able to blink spontaneously and the blink and visual threat reflexes were preserved. This deficiency was associated to a dense hemiparesis on the left side and notable aprosodia affecting language. At 3 years' follow-up the AEC had not improved significantly.

CONCLUSIONS

There are data to suggest that the right hemisphere is related to emotional perception and expressiveness, as well as the regulation of language prosody. Likewise, symbolic anthropology stresses the importance of winking as a gesture involved in non-verbal communication. These data suggest that AEC may be a consequence of a dysfunction of the role played by the right hemisphere in emotional expressiveness through gestures. The association with language aprosodia could support this hypothesis.

[Evaluation of the diagnostic value of a Spanish adaptation of the Buschke Memory Impairment Screen in the detection of dementia and cognitive impairment]

INTRODUCTION

Screening tests for dementia are a fundamental tool in specialist consultation and primary care. The instruments currently used are time-consuming and the diagnostic performance they offer is rather poor. The original version of the Buschke Memory Impairment Screen (MIS) is a quick simple test with high discriminatory power.

AIMS

Our aim was to validate a Spanish version of the MIS in specialist consultation.

PATIENTS AND METHODS

We conducted a prospective study in 91 subjects aged over 60 who visited the outpatient department for cognitive evaluation. All the patients received a similar diagnostic evaluation and the MIS was administered as a blind test. This Spanish version of the MIS was produced by means of a cross-cultural adaptation.

RESULTS

The area below the ROC curve for dementia on the MIS was 0.92, with a similar result for cognitive deterioration (CD). A cut-off score of 4 or less offered a sensitivity rate of 91.9% (CI 95%: 83.4-96.4%) and a specificity level of 81.0% (CI 95%; 70.3-88.6%) for the detection of CD. Likewise, a cut-off score of 3 or below presented a sensitivity rate of 96.1% (CI 95%: 85.7-99.3%) and a degree of specificity of 72.6% (CI 95%: 63.2-80.3%) for the detection of dementia. Interobserver and test-retest reliability (0.85 and 0.81, respectively) were adequate.

CONCLUSIONS

This version of the Buschke MIS offers a high level of discriminatory power both for dementia and for CD, as well as an adequate degree of inter and intraobserver reliability within the context of a specialist consultation. Because it is quick (less than 4 minutes) and simple to administer, MIS represents a reasonable alternative to other screening methods.

[Variables associated with functional recovery and post-discharge institutionalization of elderly cared in an average stay geriatric unit]

BASIS

To describe the evolution and results of the rehabilitation of elderly disabled cared in an average stay geriatric unit, and to define the factors associated with functional improvement and post-discharge institutionalization.

PATIENTS AND METHOD

Observational longitudinal study in 459 patients with functional disability consecutively hospitalized between May 2000 and December 2001. Basal variables collected included the clinical, functional, mental, and sociodemographic manifestations previous to the admission. The favorable functional response (defined as a functional gain during the admission of > or = 20 points in the Barthel index) and the post-discharge institutionalization were regarded the main result variables.

RESULTS

The average age of patients was 80.56 (SD: +/- 7.45) years, 64.9% were women and 81% came from acute hospital units; the main cause of disability was stroke (48.5%) followed by orthopedic pathology (26.2%) and immobility for different causes (23.5%). 72.5% of patients get functional improvement and 16.4% were institutionalized after the discharge. The main independent risk factors for poor functional response found in the multivariate analysis were a scoring in Pfeiffer's cognitive test of 5-7 points (OR: 0.42; 95% CI: 0,22-0.78) and > or = 8 (OR: 0.29; 95% CI: 0.12-0.71), and a scoring in Barthel's index < 60 prior to the deterioration (OR: 0.36; 95% CI: 0.14-0.93). Independent risk factors for institutionalization after the discharge were age (OR: 1.06; 95% CI: 1.01-1.12), and a scoring in the Gijon's sociofamiliar scale > or = 9 (OR: 6.83; 95% CI: 1.91-24.47). A functional disability after the discharge in the Barthel's index < 40 also was independently associated to post-discharge institutionalization (OR: 3,07; 95% CI: 1.04-10.06).

CONCLUSIONS

Most of elderly with recent disability benefit functionally from care in specific hospital geriatric units. Moderate or severe cognitive deterioration after hospitalization is associated to lower recovery probability. Very advanced age, higher social precariousness and severe disability after discharge are associated with higher risk of institutionalization.

Resultados al año de la rehabilitación tras fractura de fémur proximal en mayores de 84 años

OBJECTIVE

To evaluate rehabilitation outcomes at discharge and at year patients older 85 years admitted to functional treatment after hip fracture.

METHOD

A prospective study of inpatients admitted after hip fracture to medium-stay geriatric unit between May 2000 and September 2002. Baseline, clinical variables (location of fracture, serum albumin and Charlson comorbidity index), functional status assessed by Barthel Index, mobility by Physical Red Cross Scale and cognitive status by Pfeiffer questionnaire. Functional status, mobility, institutionalization and death was evaluated at discharge and by phone interview at years after discharge.

RESULTS

116 patients were studied (42% with 85 years and older, 85% women). After multivariable logistic analysis, age older than 84 years did not appear as a factor related to functional dependence or institutionalization at discharge or one year after. Indeed, oldest old age was not related with death or institutionalization and mobility dependence one year after. In the other hand, the presence of cognitive impairment at admission and functional impairment before hip fracture were independently variable associated to the presence of poor outcome at discharge and one year after.

CONCLUSIONS

Oldest old age does not appear as a independent risk factor of poor outcomes after rehabilitation of hip fracture when other related clinical, functional and mental factors are considered.

Ganancia funcional y estancia hospitalaria en la unidad geriátrica de media estancia del Hospital Central de Cruz Roja de Madrid

BACKGROUND

The medium-stay or convalescent care geriatric units were defined by the Spanish National Health Institute in 1996 as being the level of geriatric hospital care aimed at recovering those functions, activities or sequelae having undergone changes as a result of different prior processes. This study is aimed at evaluating the characteristics of patients related to functional gain and stay in medium-stay geriatric units.

METHODS

A study was made of all those patients admitted throughout the May 2000-December 2001 period. The weekly and overall functional gain was evaluated using the Barthel Index (BI), the hospital stay and the effectiveness (BI at discharge-BI at admission/during stay) having been evaluated. An improvement in the weekly gain of BI>5 points was set at the effectiveness threshold.

RESULTS

A total of 459 patients averaging age 80.56 (+/-7.45) admitted for functional recovery from sequelae of ictus (48.4%), orthopedic disorders (26.3%) and immobility due to other ailments (23.5%) were evaluated. The total functional gain was 29.71 (+/-16.75) Barthel Index points, entailing an average stay of 24.93 (+/-12.94) days and a 1.44 (+/-1.02) effectiveness. The weekly functional gain was above the threshold set during the first three weeks, independently of the age and disorder for which admitted. In the multivariate regression analysis, the age, admission due to ictus, functional impairment prior to admission, cognitive impairment at admission, comorbility and delay in admission were related to a lesser functional gain. Admission due to ictus and a better functional condition prior to admission and better cognitive condition at admission were related to a longer stay.

CONCLUSIONS

Hospital stays in medium-stay geriatric units is adequate, at least during the first three weeks. A comparison of the results among units should be adjusted by age, the disorder for which admitted, comorbility and functional and cognitive condition of the patients.

[The community activity of a hospital geriatrics service: a practical example of coordination between primary and specialized care]

OBJECTIVES

To describe the management of the geriatric hospital home assessment team to support at primary care in the need of health of geriatric patients.

DESIGN

Prospective observational study.

SETTING

5-North health district from Madrid.

PARTICIPANTS AND METHODS

All patients evaluated at home and the coordination activities between primary care and hospital geriatric service, developed by the geriatric assessment team between january 1997 at december 1999. Inquiry to primary care physicians about the usefulness of geriatric hospital home assessment team.

MAIN RESULTS

524 patients was assisted at home by the geriatric assessment team to request primary care (58.4% at all patients attended), 83.24 +/- 7.21 years old (68.1% females), with pluripathology (4.02 +/- 1.86 diagnostics) and polypharmacy (4.95 +/- 2.8), moderate-severe functional disability (Barthel Index < 60 at 65% and Red Cross functional disability > 2 at 74.4%) and frequently cognitive impairment (41.2% with Pfeiffer > 5). The main reasons of primary care to consult was functional impairment (28.4%), medical process assessment (16.2%), geriatric assessment (13.2%), skin ulcers (13.2%) and behavioral disorders (10.8%). 865 telephone call and 178 meeting in health center of primary care for consultation or medical management or for coordinating medical management was attended. 62% of primary care physician inquired to answer back. The belief of 100% answers was about de usefulness of the geriatric assessment team activity, mainly because their specialization on geriatric care (76.7%) and their responsibility of the hospital resources (65.1%).

CONCLUSIONS

The activity of geriatric hospital home assessment team is useful as support of primary care on assessment and management geriatric patients in the community and coordinate hospital and primary care to resolve health problems in this population.

[Emergency hospital admission in medical services: causes, justification, social factors, and their differences in function of age]

BACKGROUND

Increasing attention has been given to the care to elderly patients in emergency departments (ED). Moreover, few data are available about final phase of the process, that is hospital admission from ED. This study was conducted to establish appropriateness, reasons and social factors related to hospital admission in medical services from ED and their age-related differences.

METHODS

The Appropriateness Evaluation Protocol scale (AEP) was applied prospectively to 515 patients 15 years and older admitted to medical services through an ED. Patients who did not meet any AEP criteria were evaluated for other medical or social factors as conditions for their admission.

RESULTS

The sample was composed by 303 elders (65 years and older, mean age = 77 +/- 6 years) and 212 adults (15-64 years old, mean age = 45 +/- 14). 271 elderly patients (89.4%) and 173 adults (81.6%) meet AEP criteria (p = 0.01). Hospitalary admission for diagnostic procedures is more frequent in younger than in older group (14.2% versus 6.9%, p = 0.01). No differences are detected in hospital admissions based upon strictly social factors: 7 (2.3%) in elderly group and 7 (3.3%) in younger one (p = 0.05).

CONCLUSIONS

Urgent hospital admissions in medical services are justified more frequently in elderly patients. These patients are admitted for diagnostic procedures less frequently than younger group. No age-dependent difference in strictly social admissions is detected.
