Impact of the Covid-19 pandemic on palliative care provision by a hospital-based unit: results from an observational study.

Background Palliative care is a key approach in improving the quality of life of patients and their families facing the end-of-life care process. It is widely regarded as a public-health concern, especially considering the rapidly increasing end-of-life care needs worldwide. Its provision has been highly challenged by the COVID-19 pandemic emergency. Objective This study aims to analyse whether and to what extent the provision of Palliative Care to non-COVID patients provided by a hospital-based unit has changed during the COVID-19 pandemic. Material and methods A retrospective observational study was performed. All non-COVID patients admitted from October 1, 2019 to September 30, 2020 and evaluated by the hospital-based Palliative Care team were considered. Three time periods were considered: pre-lockdown, lockdown and post-lockdown. A trend analysis and multiple linear and logistic regressions to study and quantify the statistical significance of the associations were performed. Results A statistically significant positive linear trend of the number of hospitalized patients in need of Palliative Care was found over the study period. Compared to pre-lockdown, the rest of the study period presented more female and elderly patients, the length of stay and the number of patients discharged to a Hospice setting were significantly reduced. The waiting time did not change in lockdown but decreased in post-lockdown and the mortality rate was not significantly different. Also, the average number of Palliative Care consultations per patient significantly increased in the lockdown and post-lockdown. Discussion First, the significant admissions drop between the start of the pandemic and the following study period is in line with recent literature. The consequent rebound registered may be attributed to the high pressure from outside requiring admission and care. Second, the significantly older age of patients found during the lockdown than before the lockdown could be attributed to a "selection effect" of young patients, more able to delay hospitalization than the elderly, also in line with recent literature. Third, the shorter waiting time for Palliative Care activation the post-lockdown compared to the pre-lockdown period could be due to both increased hospital efficiency and to the greater pressure to discharge patients during the post-lockdown period. Also, the significant reduction in the lockdown and post-lockdown of the length of stay after Palliative Care activation could be explained considering both the greater receptivity of healthcare services outside the hospital, such as Hospices, and the greater pressure on hospital wards to discharge. Fourth, the unchanged in-hospital mortality rate remained over the entire period could be an indication of the high quality of care provided by this hospital setting to fragile patients, which is to be noted especially considering the average mortality rate registered during pandemic context in healthcare facilities. Conclusions The study aimed to quantify the impact of the COVID-19 on the provision of Palliative Care by a hospital-based team. We believe it might represent an innovative contribution and we hope similar research will be produced in order build the evidence for future challenges in this field.

Neurosurgical Defeats: Critically Ill Patients and the Role of Palliative Care Service.

The onco-functional balance in neuro-oncology requires maximizing tumor removal while rigorously preserving patients' neurological status. When postoperative worsening prevents the implementation of oncologic treatments, palliative care service offers an individualized path for symptom and psychosocial distress relief. Here, we report on a series of 25 patients operated on for malignant brain tumor who did not undergo adjuvant treatments after neurosurgery; they represented 3.9% of the whole institutional surgical series. These patients were significantly older and had a lower preoperative Karnofsky performance status than the whole cohort. Importantly, in 22 out of 25 (88%) cases, a surgical complication occurred, leading to clinical worsening in 21 patients. For the end of life, the majority of patients chose a hospice care facility (72%). While a careful selection of brain tumor patients candidate to neurosurgery is required, palliative care service provided invaluable help in coping with patients' and caregivers' needs.

Frailty Network in an Acute Care Setting: The New Perspective for Frail Older People.

The incidence of elderly patients who come to the emergency room is progressively increasing. The specialization of the physician units might not be adequate for the evaluation of this complexity. The present study aimed to present a standard procedure, called 'The Geriatric Frailty Network', operating at the Policlinico Gemelli IRCCS Foundation, which is configured specifically for the level II assessment of frail elderly patients. This was a retrospective study in 1191 patients aged over 65, who were evaluated by the Geriatric Frailty Unit directly after emergency department admission for one year. All patients underwent multidimensional geriatric evaluation. Data were collected on demographics, co-morbidity, disease severity, and Clinical Frailty Scale. Among all patients, 723 were discharged directly from the emergency room with early identification of continuity of care path. Globally, 468 patients were hospitalized with an early assessment of frailty that facilitated the discharge process. The geriatric frailty network model aims to assist the emergency room and ward doctor in the prevention of the most common geriatric syndromes and reduce the number of incongruous hospitalizations.

Infections in hospitalised patients affected by end-stage diseases: a narrative overview.

AIM: To analyse the presence and treatment of infections in hospitalised terminal patients by identifying potential risk factors. METHODS: We conducted a retrospective study using health data from 229 terminally ill patients (evaluated by our hospital palliative care team (HPCT) hospitalised from January to December 2018. RESULTS: A total of two types of infections were identified: blood flow infection (through blood cultures) and pneumonia (through radiological examinations), while the other cases of infection remained unknown. The most frequently identified microorganism was Staphylococcus spp. The prevalence of infections was higher in patients with non-oncological diseases (n=47, 36.7%; p value 0.009). The potential risk factors identified for infections were the presence of: Parkinson's disease (n=15, 11.7%; p value 0.005), dysphagia (n=49, 38.3%; p value 0.007), bedding (n=15, 11.7%; p value 0.048), pressure ulcers (n=31, 24. 2%); p value 0.018), oxygen therapy (n=60, 46.9%; p value 0.050), urinary catheters (n=95, 74.2%; p value 0.038) and polypathology (2.3 vs 1.7; p value 0.022). Parkinson's disease (OR=5.973; 95% CI=1.292-27.608), dysphagia (OR=2.090; 95% CI=1.080-4.046) and polypathology (OR=1.220; 95% CI=1.015-1.466) were confirmed by a corrected logistic regression analysis. CONCLUSIONS: Infections and, consequently, antibiotic therapies, have a high prevalence in hospitalised patients with terminal disease. Potential risk factors for infections in these patients could be polypathology, dysphagia and Parkinson's disease. Patients with these conditions could benefit from prevention programmes.

Frailty in Elderly Patients with Covid-19: A Narrative Review.

Introduction: The SARS CoV-2 pandemic still generates a very high number of affected patients and a significant mortality rate. It is essential to establish objective criteria to stratify COVID-19 death risk. Frailty has been identified as a potential determinant of increased vulnerability in older adults affected by COVID-19, because it may suggest alterations of physical performance and functional autonomy. Methods: We have conducted a narrative review of the literature on the evidences regarding COVID-19 and the frailty condition. Thirteen observational studies were included. Conclusion: Data emerging from the studies indicate that older COVID-19 patients with a frailty condition have an increased risk of mortality compared with non-frail patients, and this association is independent of other clinical and demographic factors. A frailty evaluation is required to help clinicians to better stratify the overall risk of death for older patients with COVID-19.

Characteristic of IgA and IgG antibody response to SARS-CoV-2 infection in an Italian referral COVID-19 Hospital.

INTRODUCTION: Antibody response plays a fundamental role in the natural history of infectious disease. A better understanding of the immune response in patients with SARS-CoV-2 infection could be important for identifying patients at greater risk of developing a more severe form of disease and with a worse prognosis. METHODS: We performed a cross-sectional analysis to determine the presence and the levels of both anti-SARS-CoV-2 IgG and IgA in a cohort of hospitalized patients with confirmed infection at different times in the natural history of the disease. Patients enrolled when admitted at the emergency department were prospectively followed up during hospital stay. RESULTS: Overall, 131 patients were considered with a total of 237 samples processed. Cross-sectional analysis showed that seroconversion for IgA seems to occur between days 6 and 15, while IgG response seems to occur slightly later, peaking at day 20 after symptoms onset. Both IgA and IgG were maintained beyond 2 months. Severe patients showed a higher IgA response compared with mild patients when analyzing optical density (8.3 versus 5.6, p < 0.001). Prospective analysis conducted on 55 patients confirmed that IgA appear slightly earlier than IgG. After stratifying for the severity of disease, both the IgA and IgG responses were more vigorous in severe cases. Moreover, while IgG tended to stabilize, there was a relevant decline after the first month of IgA levels in mild cases. CONCLUSION: IgA and IgG antibody response is closely related, although seroconversion for IgA occurs earlier. Both IgA and IgG are maintained beyond 2 months. Severe patients showed a more vigorous IgA and IgG response. IgA levels seem to decline after 1 month since the onset of symptoms in mild cases. Our results should be interpreted with cautions due to several limitations in our study, mainly the small number of cases, lack of data on viral load and clinical setting.

The Geriatrician: The Frontline Specialist in the Treatment of COVID-19 Patients.

On February 20, 2020, a man living in the north of Italy was admitted to the emergency room with an atypical pneumonia that later proved to be COVID-19. This was the trigger of one of the most serious clusters of COVID-19 in the world, outside of China. Despite aggressive restraint and inhibition efforts, COVID-19 continues to increase, and the total number of infected patients in Italy is growing daily. After 6 weeks, the total number of patients reached 128,948 cases (April 5, 2020), with the higher case-fatality rate (15,887 deaths) dominated by old and very old patients. This sudden health emergency severely challenged the Italian Health System, in particular acute care hospitals and intensive care units. In 1 hospital, geriatric observation units were created, the experience of which can be extremely useful for European countries, the United States, and all countries that in the coming days will face a similar situation.

The benefits of a hospital palliative care team.

AIM: To investigate the association between a hospital palliative care unit assessment and hospital outcome. METHODS: This was a prospective cohort study. Data were assessed from all patients treated and followed by the hospital palliative care team (HPCT) from November 2016 until December 2017. RESULTS: The mean age of the 588 patients was 73.15±13.6 years. All of the patients included in the study were referred to palliative care. A large proportion of patients were affected by cancer, 69.7% (410), while 30.3% (178) were affected by an advanced chronic illness. The three most frequent cancers were: gastrointestinal (n=81, 19.8%), gynaecological (n=66, 16.1%) and lung (n=63, 15.4%); the three most frequent chronic advanced diseases were: advanced dementia (n=45, 25.3%), severe ischaemic/haemorrhagic stroke (n=36, 20.2%) and severe heart failure (n=25, 15.3%). The majority of patients were in clinical wards (n=476, 81.0%) and the average length of stay was 22.9 days. Hospital outcome trends were evaluated in terms of length of stay and number of deaths that occurred in the hospital. In particular, length of stay decreased from 25.8 days to 18.1 days, hospital death from 13 to 0 during the time that the HPCT assessed patients for an appropriate discharge. CONCLUSION: The HPCT is an effective means of managing patients affected by severe illness, reducing the number of deaths that occur within the hospital, long periods of hospitalisation and instances of readmission. However, further studies are required to fully assess the impact of an HPCT on hospital outcomes.

The new metabolic treatments for sarcopenia.

In terms of managing sarcopenia, many studies have shown that physical activity (in particular resistance exercise) and specific nutrition interventions such as protein and amino acids supplementation can improve muscle mass and strength in older adults. Moreover, several drugs have been suggested to have an impact on muscle outcomes, with various levels of scientific evidence. In the present paper we have reviewed the evidence regarding the effect of some new metabolic agents (vitamin D, leucine, ß-hydroxy ß-methylbutyrate, citrulline malate, ornithine, isoflavones) on sarcopenia and muscular outcomes in older adults. For each metabolic agent, we have also discussed the biological plausibility of the described effect.

Association of anorexia with sarcopenia in a community-dwelling elderly population: results from the ilSIRENTE study.

OBJECTIVE: There is increasing evidence that anorexia of aging can cause physical and mental impairment. The aim of the present study was to evaluate the relationship between anorexia and sarcopenia in elderly persons aged 80 years or older. METHODS: Data are from the baseline evaluation of 354 subjects enrolled in the ilSIRENTE study. The ilSIRENTE study is a prospective cohort study performed in the mountain community living in the Sirente geographic area (L'Aquila, Abruzzo) in Central Italy. We defined anorexia as the presence of loss of appetite and/or lower food intake. According to the European Working Group on Sarcopenia in Older People (EWGSOP) criteria, diagnosis of sarcopenia required the documentation of low muscle mass plus the documentation of either low muscle strength or low physical performance. The relationship between anorexia and sarcopenia was estimated by deriving odds ratios from the multiple logistic regression models considering sarcopenia as the dependent variable. RESULTS: Nearly 21 % of the study sample showed symptoms of anorexia. Using the EWGSOP-suggested algorithm, 103 subjects (29.1 %) with sarcopenia were identified. Thirty-four (46.6 %) participants were affected by sarcopenia among subjects with anorexia compared to 69 subjects [24.6 %] without anorexia (p < 0.001). After adjusting for potential confounders including age, gender, functional and cognitive impairment, physical activity, urinary incontinence, comorbidity, congestive heart failure, COPD, depression, anti-cholinergic drugs, and TNF-α plasmatic levels, participants with anorexia had a higher risk of sarcopenia compared with non-anorexic subjects (HR 1.88, 95 % CI 1.01-3.51). CONCLUSIONS: Anorexia is common among community-dwelling older subjects in Italy. Our results suggest that among old-old subjects, anorexia is independently associated with sarcopenia.

Common geriatric conditions and disabilities in older persons with chronic obstructive pulmonary disease.

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) is one of the most prevalent chronic diseases among older persons worldwide and the rapid increase in commonly associated COPD-disabilities requires urgent awareness among healthcare professionals. The presence of pulmonary and extrapulmonary comorbidities is highly prevalent among COPD patients and complicates treatment management, especially in advanced age. Some of the most common geriatric conditions in COPD patients lead to respiratory function decline, physical function impairment with limited physical performance, cognitive decline, and depression. Unfortunately, the activation of each component may lead to the progression of the other, which, if not corrected, will lead to critical clinical outcomes such as disability (as seen by the worsening of each condition) and death. RECENT FINDINGS: Studies in older persons with COPD have shown that disability is mainly due to the severity of comorbidities that have been shown to significantly impact treatment options and the prognosis for such individuals. In addition to spirometric functional parameters, exercise performance and efficacy of specific therapeutic interventions may be useful indicators for overall health status and outcomes. The scientific literature underlines the necessity to use additional parameters other than spirometry for COPD patient monitoring. SUMMARY: As disability is a growing phenomenon in COPD and substantially impacts patient perception of the disease, we will highlight the recent literature regarding the importance of common geriatric conditions leading to disability in older COPD patients. In particular, we will discuss the impact of the following conditions in older patients with COPD: respiratory function decline, physical function impairment, and mood disorders. Clinical use for measuring such parameters in COPD elderly will aid in identifying those at risk for severe clinical decline.

Anorexia, physical function, and incident disability among the frail elderly population: results from the ilSIRENTE study.

OBJECTIVE: Increasing evidence suggests that anorexia of aging can cause physical and mental impairment. The aim of the present study was to evaluate the relationship between anorexia of aging and measures of physical performance, muscle strength, and functional status in older persons aged 80 years or older. METHODS: Data are from baseline evaluation of 364 subjects enrolled in the ilSIRENTE study. The ilSIRENTE study is a prospective cohort study performed in the mountain community living in the Sirente geographic area (L'Aquila, Abruzzo) in central Italy. Physical performance was assessed using the physical performance battery score (SPPB), which is based on 3 timed tests: 4-meter walking speed, balance, and chair stand tests. Muscle strength was measured by hand grip strength. We defined anorexia as the presence of loss of appetite and/or lower food intake. Analyses of covariance were performed to evaluate the relationship of anorexia with physical function. RESULTS: In the unadjusted model, all the physical performance, muscle strength, and functional measures showed significant associations with the presence of anorexia. After adjustment for potential confounders (age, gender, BMI, number of diseases, depression, congestive heart failure, lung diseases) these associations were weaker but still statistically significant (physical performance battery score: subjects without anorexia 6.8, SE 0.2, subjects with anorexia 5.8, SE 0.4, P = .03; 4-meter walking speed: subjects without anorexia 0.5 m/s, SE 0.1, subjects with anorexia 0.3 m/s, SE 0.1, P = 5.001 hand grip strength: subjects without anorexia 30.8 kg, SE 0.7, subjects with anorexia 27.9 kg, SE 1.5, P = .03). Furthermore, relative to participants without anorexia, those subjects with anorexia showed a significantly higher risk of developing disability after 2 years of follow-up (hazard ratio 2.25; 95% confidence intervals 1.15-4.39). CONCLUSIONS: Anorexia is common among community older subjects in Italy. Our results suggest that among old-old subjects, the presence of anorexia is associated with impaired physical performance and with a significant increased risk of incident disability, irrespective of potential confounders.

Disability, more than multimorbidity, was predictive of mortality among older persons aged 80 years and older.

OBJECTIVE: In this study, we evaluate the impact of disability and multimorbidity on the risk of all-cause death in a population of frail older persons living in community. STUDY DESIGN AND SETTING: We analyzed data from the Aging and Longevity Study in the Sirente geographic area, a prospective cohort study that collected data on all subjects aged 80 years and older (n=364). The main outcome measure was all-cause mortality over 4-year follow-up. RESULTS: A total of 150 deaths occurred. Sixty-seven subjects (44.6%) died in the nondisabled group compared with 83 subjects (55.3%) in the disabled group (P<0.01). Thirty-nine subjects (31.7%) died among subjects without multimorbidity compared with 111 subjects (46.0%) with two or more diseases (P<0.01). When examining the combined effect of multimorbidity and disability, the effect of disability on the risk of death was higher than that of multimorbidity. After adjusting for potential confounders, relative to those without disability and multimorbidity, disabled subjects showed an increased risk of death when multimorbidity was associated (hazard ratio [HR]=3.91; 95% confidence interval [CI]=1.53-10.00) and in absence of multimorbidity (HR=2.36; 95% CI=0.63-8.83). CONCLUSION: Our results show that disability exerts an important influence on mortality, independently of age and other clinical and functional variables.

Predictors of rehabilitation outcome among frail elderly patients living in the community.

BACKGROUND AND PURPOSE: Physical therapy is frequently offered to community-dwelling frail elderly as part of home care rehabilitation programs. A better knowledge of predictors of rehabilitative success could allow a better targeting of limited resources. The purpose of this study is to evaluate the association of medical indicators of health status on functional recovery during rehabilitation of frail elderly living in the community. SUBJECTS: Subjects included 598 patients aged 70 years or more admitted consecutively to a home care rehabilitation program from January 2004 to December 2004. METHODS: A comprehensive geriatric multidisciplinary evaluation was offered to all patients, based on the Minimum Data Set for Home Care (MDS-HC) assessment form. Predictors of functional recovery were identified by a multiple logistic regression model. Data analyses were based on the items contained in the MDS-HC form. RESULTS: An improvement in ADL score was seen in 33% of patients, while the others remained unchanged or worsened. In multivariate analysis the negative predictors of functional improvement were as follows: cognitive impairment (OR 0.67; CI 0.60-0.74), depression (OR 0.89, CI 0.82-0.96), visual (OR 0.32, CI 0.21-0.50) and hearing impairment (OR 0.42, CI 0.27-0.67), and urinary (OR 0.21, CI 0.14-0.33) and bowel incontinence (OR 0.16, CI 0.10-0.26). CONCLUSIONS: Cognitive impairment, depressed mood, sensory impairment, and incontinence are key factors that need to be assessed in order to individuate patients at risk of failure in rehabilitation. A targeted intervention in these areas could offer the opportunity of improving rehabilitation outcome.

Physical activity and risk of cognitive impairment among older persons living in the community.

BACKGROUND AND AIMS: Despite growing interest in the physical and environmental factors associated with the risk of cognitive decline, there is still a lack of information explaining whether they are related to each other. The aim of the present study was to evaluate the relationship of lifetime physical activity with cognitive performance in older persons aged 80 years or older. METHODS: Data are from the baseline evaluation of the ilSIRENTE Study (n=364). Cognitive performance was assessed using a 6-item, 7-category scale [Cognitive Performance Scale (CPS)]. The questionnaire in the ilSIRENTE study form contained one item asking respondents about the frequency of light and high physical activity. Analysis of covariance (ANCOVA) was used to examine the effect of different levels of physical activity on cognitive performance, after adjustment for potential confounding variables. RESULTS: The mean age of 364 subjects participating in the study was 85.9 (standard deviation [SD] 4.9) years, and 244 (67.0%) were women. Of the total sample, 158 subjects (43%) had a history of high intensity physical activity during young age; the rate of high intensity physical activity was lower during adult age and old age (125 and 67 subjects, respectively). After adjustment for potential confounders, individuals with a history of high intensity physical activity had a significantly lower CPS score (indicating better performance) than other participants, independently of the age period considered. CONCLUSIONS: The present study suggests that, among old-old subjects living in the community, a history of high physical activity is associated with better cognitive performance.

Depression and physical function: results from the aging and longevity study in the Sirente geographic area (ilSIRENTE Study).

Depression in older persons represents a major issue because of its relevant prevalence and the associated higher risk of adverse health-related events. The aim of this study was to evaluate the relationship of depressive symptoms with measures of physical performance, muscle strength, and functional status. Data are from baseline evaluation of the ilSIRENTE Study (n = 364). Physical performance was assessed using the Short Physical Performance Battery and the 4-meter walking test. Muscle strength was measured by hand-grip strength. Functional performance was assessed using Basic and Instrumental Activities of Daily Living. Depression was defined by analyzing the different depressive manifestations included in the Minimum Data Set for Home Care Form: verbal expression of sad and/or anxious mood and demonstrated signs of mental distress. Analyses of covariance and linear regressions were performed to evaluate the relationship between depression and physical function. Participants with depression showed significantly worse results in all of the physical function tests. Subjects with depression presented significantly lower adjusted mean results for the 4-meter walking test (0.41 m/s; SE, 0.03) and the Short Physical Performance Battery score (5.68; SE, 0.38) compared with those without depression (0.50 m/s; SE, 0.01 and 6.93; SE, 0.21; all P < .01, respectively). Participants with depressed mood also presented a higher number of impaired instrumental activities of daily living (3.69; SE, 0.25) compared with participants with less than 3 depressive symptoms (2.85; SE, 0.14; P = .005). No significant difference was reported for the hand-grip strength and the Basic Activities of Daily Living scale. In conclusion, physical performance and functional status measures are significantly and negatively influenced by the presence of depression in community-dwelling older persons aged 80 years and older.

Impact of inappropriate drug use on physical performance among a frail elderly population living in the community.

OBJECTIVE: The criteria for inappropriate drug use developed by Beers have been widely used in drug utilization reviews to assess the quality of prescribing, but there is still inconclusive evidence that these criteria can impact on patient outcomes. The aim of the present study was to evaluate the relationship between the use of inappropriate drugs and measures of physical performance, muscle strength and functional status in an elderly population (80+ years). METHODS: Data are from the baseline evaluation of 364 subjects enrolled in the ilSIRENTE study, a prospective cohort study performed in a mountain community living in the Sirente geographic area (L'Aquila, Abruzzo) in Central Italy. Physical performance was assessed using the physical performance battery score (SPPB), which is based on three timed tests: 4-m walking speed, balance and chair stand tests. Muscle strength was measured by hand grip strength. Inappropriate drug use was defined by the 2003 Beers criteria. Analyses of covariance were performed to evaluate the relationship of inappropriate drugs with physical function. RESULTS: In the unadjusted model, all of the physical performance, muscle strength and functional measures showed significant associations with inappropriate drug use. Following adjustment for potential confounders, which included age, gender, physical activity level, cognitive performance scale, comorbidity, lung diseases and diabetes, these associations were still statistically significant for the physical performance battery score [non-users inappropriate drugs: 7.0; standard error (SE): 0.1; users inappropriate drugs: 6.1; SE: 0.2; p = 0.007] The 4-m walking speed, physical performance battery score and Total Activities of Daily Living (ADL) scale score showed worsening results among subjects using two inappropriate medications compared with subjects using one inappropriate drug or none at all. CONCLUSIONS: The use of inappropriate medication (as defined by Beers 2003 criteria) was found to be common among the elderly Italian study cohort living in the community. Our results suggest that among old-old subjects the use of inappropriate drugs is associated with impaired physical performance.

Anemia status, hemoglobin concentration, and mortality in nursing home older residents.

BACKGROUND: Anemia status is a typical feature of the "frailty syndrome" of elderly subjects. Increasing evidences suggest that low hemoglobin concentration is common in elderly subjects and adversely affects morbidity and mortality. OBJECTIVE: In the present study, we evaluate the impact of hemoglobin concentration on the risk of all-cause mortality in a large population of frail and old subjects living in a nursing home. METHODS: There were 372 residents admitted to the teaching nursing home of Catholic University of Rome aged 65 years and older from January 2002 to November 2004 who were enrolled. For the present study we selected all the subjects with a full MDS-NH assessment within 14 days after admission. The main outcome measure was the relative hazard ratio of death after 2 years of follow-up for different levels of hemoglobin concentration. RESULTS: Based on the WHO criteria for anemia, 235 participants were anemic at enrollment (63.1% of the cohort). A total of 130 deaths (44 men and 86 women) occurred during 2-years of follow-up. Death rates for those with and without anemia based on the WHO criteria were 38% and 28%, respectively (P = .03). The age- and sex-adjusted hazard ratio for mortality was 1.56 (95% CI, 1.07-2.28) for persons with anemia. Compared with the lower tertile, the age- and sex-adjusted hazard ratios of mortality for hemoglobin in the second and third tertiles were 0.40 (95% CI, 0.26-0.61), and 0.39 (95% CI, 0.24-0.58), respectively. Adjusting for potential confounders, including markers of frailty, cognitive impairment, creatinine levels, cancer, stroke, body mass index, and pressure ulcer, somewhat reduced the strength of the association between hemoglobin level and mortality, but it remained statistically significant. CONCLUSION: Our results obtained from a representative sample of very old and frail elderly subjects living in a nursing home expand the knowledge that high levels of hemoglobin are associated with better survival. Anemia should be actively sought, appropriate diagnostic strategies should be implemented to search for potentially correctable causes, and aggressive interventions may be warranted to reduce mortality and improve functional status.

In a prospective observational study, influenza vaccination prevented hospitalization among older home care patients.

OBJECTIVE: The aim of the study is (1) to describe the prevalence of vaccination against influenza in older home care patients and (2) to investigate the protective effect of influenza vaccination for hospitalization events. STUDY DESIGN AND SETTING: This is an observational study conducted in four large cohorts of elderly patients in home care during the 1998-1999, 1999-2000, 2000-2001, and 2001-2002 influenza seasons. We analyzed data from the Italian Silver Network Home Care project. A total of 2,201 patients were enrolled in the present study. The main outcome measures were prevalence of vaccination against influenza and the rate of hospitalization according to vaccination status and influenza season. RESULTS: The rate of influenza vaccination was around 48% of the studied sample. During the follow-up including the peak of influenza and the total influenza season, 412 subjects (40%) were hospitalized among vaccinated compared to 610 subjects (59%) among not vaccinated (P<0.001). After adjusting for age, gender, location of home care program, and all the variables significantly different between vaccinated and not-vaccinated subjects, vaccinated subjects were less likely to be hospitalized compared to not-vaccinated subjects (OR, 0.73; 95% CI 0.60-0.90). CONCLUSIONS: Vaccination against influenza has an important prognostic implication for frail geriatric patients living in the community.

Comorbidity and physical function: results from the aging and longevity study in the Sirente geographic area (ilSIRENTE study).

BACKGROUND: Physical function measures have gained increased importance in the evaluation of older persons. The presence of comorbidity is a major and growing issue in geriatrics. OBJECTIVE: To evaluate the relationship between comorbidity and physical function in community-dwelling older persons. METHODS: Data are from baseline evaluation of the ilSIRENTE study (n = 364). Physical performance was assessed using the Short Physical Performance Battery (SPPB) and the 4-meter walking test. Muscle strength was measured by hand-grip strength. Functional performance was assessed using Basic and Instrumental Activities of Daily Living (ADLs and IADLs, respectively). Comorbidity was defined as >or=3 clinical conditions. Analyses of covariance and linear regressions were performed to evaluate the relationship between comorbidity and physical function. RESULTS: The mean age of participants was 85.9 (SD = 4.9) years. About one third (37.4%) of participants reported >or=3 clinical conditions. Participants with comorbidity had significantly worse results in all the physical function tests. Participants with comorbidity had significantly lower adjusted results for the 4-meter walking test (0.444 m/s) and the SPPB score (6.131) compared to those without comorbidity (0.531 m/s and 7.221; all p = 0.001, respectively). Participants with comorbidity were more IADL-impaired (3.152) than participants without comorbidity (2.767; p = 0.04). No significant association of ADLs and hand-grip strength with comorbidity was reported. Similar strengths of association for the 4-meter walking test (per SD increase, beta = -0.280; p = 0.001) and the SPPB (per SD increase, beta = -0.285; p = 0.001) with comorbidity were reported. CONCLUSIONS: Physical function measures, especially walking speed and SPPB, are associated with comorbidity. Physical performance measures may improve the clinical evaluation of older persons.
