Community care in Europe. The Aged in Home Care project (AdHOC).

BACKGROUND AND AIMS: Community care for older people is increasing dramatically in most European countries as the preferred option to hospital and long-term care. While there has been a rapid expansion in Evidence-Based Medicine, apart from studies of specific interventions such as home visiting and hospital at home (specialist visits or hospital services provided to people in their own homes in the community), there is little evidence of characteristics of the recipients of community care services or the organisation of services that produce the best outcomes for them and their informal carers. The AdHOC Study was designed to compare outcomes of different models of community care using a structured comparison of services and a comprehensive standardised assessment instrument across 11 European countries. This paper describes the study and baseline data. METHODS: 4,500 people 65 years and older already receiving home care services within the urban areas selected in each country were randomly sampled. They were assessed with the MDS-HC (Minimum Data Set-Home Care) instrument, containing over 300 items, including socio-demographic, physical and cognitive characteristics of patients as well as medical diagnoses and medications received. These data were linked to information on the setting, services structures and services utilization, including use of hospital and long-term care. After baseline assessment, patients were re-evaluated at 6 months with an abbreviated version of the instrument, and then at the end of one year. Data collection was performed by specially-trained personnel. In this paper, socio-demographics, physical and cognitive function and provision of hours of formal care are compared between countries at baseline. RESULTS: The final study sample comprised 3,785 patients; mean age was 82+/-7.2 years, 74.2% were females. Marital and living status reflected close family relationships in southern Europe relative to Nordic countries, where 5 times as many patients live alone. Recipients of community care in France and Italy are characterised by very high physical and cognitive impairment compared with those in northern Europe, who have comparatively little impairment in Activities of Daily Living and cognitive function. The provision of formal care to people with similar dependency varies extremely widely with very little formal care in Italy and more than double the average across all levels of dependency in the UK. CONCLUSIONS: The AdHOC study, by virtue of the use of a common comprehensive standardised assessment instrument, is a unique tool in examining older recipients of community care services in European countries and their widely varied organisation. The extreme differences seen in dependency and hours of care illustrate the probable contribution the study will make to developing an evidence based on the structure, quantity and targeting of community care, which will have major policy implications.

Comorbidity and social factors predicted hospitalization in frail elderly patients.

OBJECTIVE: Studies on factors predicting the hospital admission of geriatric patients have reported different findings. The present study was undertaken to examine the rate of hospitalization among a large sample of frail elderly people living in the community and to identify the most important clinical and patient-centered factors associated with the hospital admission. STUDY DESIGN AND SETTING: This is an observational cohort study. All patients (n = 1,291) in six Italian home health care agencies were assessed by a trained staff who collected data on the Minimum Data Set for Home Care (MDS-HC) form. We constructed a longitudinal database including MDS-HC data and information on hospital utilization by each patient. RESULTS: During the follow-up of 12 months, the rate of hospitalization was about 26% of the studied sample. Persons living alone were more likely to have a hospital admission than those living with an informal caregiver (odds ratio OR = 2.59, 95% confidence interval CI = 1.82-3.69). Similarly, persons with economic hardship were more frequently hospitalized than those without these problems(OR = 3.01, 95% CI = 1.75-5.18). Comorbidity and previous hospital admission were associated with a higher risk to be hospitalized, too. CONCLUSION: Our results support the hypothesis that a mix of social and health problems are independent predictors of hospitalization. Identification of those factors that best predict hospital admissions and readmissions gives direction for potential interventions and further research toward reducing unnecessary hospitalizations.

Use of angiotensin-converting enzyme inhibitors in elderly people with heart failure: prevalence and outcomes.

BACKGROUND: There is a lack of information on the effects of angiotensin-converting enzyme (ACE) inhibitors in very old people with heart failure (HF). The objective of this study is to estimate the prevalence of prescriptions of ACE inhibitors in elderly people with HF discharged from acute care hospitals, and to evaluate the effect of these drugs on 1-year mortality rates. METHODS: We used data from the Gruppo Italiano di Farmacovigilanza nell'Anziano (GIFA). In 1998, we undertook a 1-year longitudinal study on elderly people (aged 65+ years) discharged with a diagnosis of HF. We compared the demographic and clinical characteristics associated with a prescription at discharge of ACE inhibitors, and used a Cox proportional hazard regression model to calculate the relative hazard of dying associated with the use of ACE inhibitors. RESULTS: We enrolled 818 patients in the study with a mean age of 79 years (range: 65-101 years). One fourth of the participants were aged 85 years or older. ACE inhibitors were prescribed to 550 patients (67.2%) at discharge. Older age and physical disability were negatively correlated with the use of ACE inhibitors. People using ACE inhibitors had a 40% reduction of mortality (HR [hazard ratio]: 0.60; 95% CI [confidence intervals]: 0.42-0.88). The reduction in mortality was much stronger among disabled people (HR: 0.35; 95% CI: 0.19-0.64). CONCLUSION: ACE inhibitors are still underprescribed among elderly people with HF discharged from acute care hospitals. Even in this frail, elderly population, we found a beneficial effect of ACE inhibitors. There is room to further improve the quality of care for elderly people with HF.

Physical activity and mortality in frail, community-living elderly patients.

BACKGROUND: The authors describe the prevalence of moderate-intensity physical activity in a population of older persons living in the community. In addition, they explore the relationship between physical activity and mortality. METHODS: In this longitudinal observational study, the authors analyzed data from patients admitted to home care programs collected as part of the Italian Silver Network Home Care project. Twelve home health agencies participated in the project, which evaluated the implementation of the Minimum Data Set for Home Care (MDS-HC) instrument. A total of 2757 patients were enrolled in the current study. The primary outcome measures were the prevalence of 2 or more hours per week of physical activity and survival. RESULTS: Fewer than 20% of patients had regular physical activity. During a median follow-up period of 10 months from the initial MDS-HC assessment, 442 (16%) patients died. After adjusting for sex, physical and cognitive disability, and all potential risk factors for death, active patients were less likely to die compared with those with no or very low-intensity physical activity (relative risk ratio [RR], 0.51; 95% confidence interval [CI], 0.35-0.73). This inverse relationship was also significant in patients aged 80 years and older (RR 0.55; 95% CI, 0.32-0.95). CONCLUSIONS: Physical activity is associated with a significantly lower risk of all-cause mortality. The current findings support the possibility that moderate-intensity physical activity has an independent effect on survival even among frail and old persons.

Treatment of benign positional vertigo in the elderly: a randomized trial.

OBJECTIVES/HYPOTHESIS: The objective of the study was to evaluate the efficacy of three therapeutic strategies (Semont maneuver, flunarizine, and no treatment) in patients with benign paroxysmal positional vertigo. STUDY DESIGN: Randomized prospective trial. METHODS: One hundred fifty-six consecutive patients older than 60 years of age who were affected by benign paroxysmal positional vertigo of the posterior semicircular canal were enrolled. The diagnosis was made on the basis of the history of recurrent sudden crisis of vertigo and positional-induced typical nystagmus after Dix-Hallpike positioning maneuver. Patients were randomly allocated to receive Semont liberatory maneuver (intended as a statoconia-detachment maneuver), flunarizine, or no treatment. A post-treatment negative Dix-Hallpike test result was considered as a proof of vertigo resolution. RESULTS: Cure rates with Semont maneuver were significantly higher (94.2%) than those obtained with flunarizine (57.7%) and no treatment (36.4%) (P <.001). Within a 6-month follow-up, relapse rates were lower among patients treated with Semont maneuver (3.8%) than those obtained with flunarizine (5.8%) and no treatment (21.1%). All patients with resolution of symptoms and negative Dix-Hallpike test results showed a great improvement in daily activities and quality of life (P <.001). CONCLUSION: Semont liberatory maneuver is the most successful therapy for benign paroxysmal positional vertigo and improves patients' quality of life. Diagnostic and therapeutic maneuvers are easy to perform and should be part of the medical knowledge of every general practitioner and geriatrician.

Pharmacoepidemiology and disability in older adults: can medications slow the age-related decline in physical function?

Age-related disability and loss in physical function are growing public health priorities. Loss in physical function seriously threatens the independence and quality of life of older adults and has a significant social and economic impact on our society. Despite the fact that the negative impact of adverse drug reaction and inappropriate drug use on disability has been widely studied, there is limited evidence regarding the efficacy of pharmacological interventions to prevent decline in physical function among older populations. The effect of statins, angiotensin-converting enzyme inhibitors and testosterone on physical performance in older adults are reviewed. In clinical studies these drugs have recently shown promising effects on the prevention of disability and decline in physical function in older adults. The findings of these studies are not definite and need to be confirmed in large clinical trials.

NSAID-related psychiatric adverse events: who is at risk?

NSAIDs are frequently used in clinical practice and they account for approximately 5-10% of all drug prescriptions. NSAID use has been associated with a risk of adverse events, which have a relevant impact on morbidity and mortality and account for a substantial increment of healthcare costs. Less common, but clinically relevant, adverse events associated with NSAID use are the impairment of the CNS and, particularly, the appearance of psychiatric symptoms. These symptoms include changes in cognition, mood state and even precipitation or exacerbation of pre-existing psychiatric disorders. This article aims to review the medical literature on published reports of NSAID-related psychiatric adverse events, identify risk factors for these events and describe mechanisms potentially involved in their onset. We identified 27 reports with data on 453 cases of NSAID-related psychiatric adverse events. Data suggest that individuals who may be particularly susceptible to such events include patients with a history of psychiatric illness and possibly parturients. Indometacin and selective cyclo-oxygenase (COX)-2 inhibitors were the most frequently reported culprit drugs; however, whether this reflects an increased incidence with these drugs compared with other NSAIDs or factors such as usage or reporting patterns is unknown.A possible explanation for the psychiatric effect of NSAIDs resides in the modulation of central neurotransmission by prostaglandins, the synthesis of which is inhibited by NSAIDs. COX-2 is a key enzyme in this process since its activity is localised in distal dendrites and dendritic spines, which are cellular specialisations involved in synaptic signalling. Dopamine is considered the most relevant neurotransmitter involved in this phenomenon. Psychiatric symptoms are a rare but relevant complication of NSAID use. This effect is probably a consequence of impairment in neurotransmission modulated by prostaglandins when NSAIDs are used by susceptible individuals. These drugs should be used with caution in high-risk individuals with pre-existing psychiatric illness, and caution may also be advisable in the postpartum period. To date, reports of NSAID-related psychiatric adverse events have most commonly involved indometacin and selective COX-2 inhibitors. Prescribers should consider warning patients of the possibility of an acute neuropsychiatric event when traditional NSAIDs or selective COX-2 inhibitors are prescribed.

Topical treatment of pressure ulcers with nerve growth factor: a randomized clinical trial.

BACKGROUND: The prevalence of pressure ulcers of the foot is a major health care problem in frail elderly patients. A pressure sore dramatically increases the cost of medical and nursing care, and effective treatment has always been an essential nursing concern. Management options for pressure ulcers include local wound care; surgical repair; and, more recently, topical application of growth factors. OBJECTIVE: To examine the effects of topical treatment with nerve growth factor in patients with severe, noninfected pressure ulcers of the foot. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Teaching nursing home of Catholic University of the Sacred Heart, Italy. PATIENTS: 36 persons with pressure ulcers of the foot. INTERVENTION: 18 patients received nerve growth factor treatment, and 18 patients received only conventional topical treatment. MEASUREMENTS: The course of the ulcers during follow-up was evaluated by tracing the perimeter of the wound onto sterile, transparent block paper and determining the stage. RESULTS: At baseline, the treatment and control groups did not differ across demographic variables, clinical characteristics, and functional measures. The mean area (+/-SD) of the ulcers was 1012 +/- 633 mm2 in the treatment group and 1012 +/- 655 mm2 in the control group (P > 0.2). The average reduction in pressure ulcer area at 6 weeks was statistically significantly greater in the treatment group than in the control group (738 +/- 393 mm2 vs. 485 +/- 384 mm2; P = 0.034). CONCLUSION: Topical application of nerve growth factor may be an effective therapy for patients with severe pressure ulcers.

The effects of cognitive impairment on mortality among hospitalized patients with heart failure.

PURPOSE: Cognitive impairment is a common, potentially reversible condition among older patients with heart failure. Because cerebral metabolic abnormalities have been associated with reduced survival in younger patients with advanced heart failure, we assessed the effect of cognitive impairment on the survival of older patients with heart failure. METHODS: The association between cognitive dysfunction and in-hospital mortality was assessed in 1113 patients (mean [+/- SD] age, 78 +/- 9 years) who had been admitted for heart failure to 81 hospitals throughout Italy. One-year mortality was assessed in 968 patients with heart failure (age, 76 +/- 10 years) participating in the same study. Cognitive impairment was defined as a Hodkinson Abbreviated Mental Test score <7. RESULTS: In-hospital death occurred in 65 (18%) of the 357 participants with cognitive impairment and in 26 (3%) of the 756 patients with normal cognition (P <0.0001). Out-of-hospital mortality was 27% (51/191) among patients with cognitive impairment and 15% (115/777) among other participants (P <0.0001). In multivariate Cox regression models, decreasing levels of cognitive functioning were associated with increasing in-hospital mortality; cognitive impairment was associated with an almost fivefold increase in mortality (relative risk = 4.9; 95% confidence interval: 2.9 to 8.3) after adjusting for several potential confounders. CONCLUSION: Cognitive impairment is an independent prognostic marker in older patients with heart failure. Assessment of cognitive functioning, even by simple screening tests, should be part of the routine assessment of elderly patients with heart failure.

Inappropriate medication use among hospitalized older adults in Italy: results from the Italian Group of Pharmacoepidemiology in the Elderly.

OBJECTIVE: To determine the prevalence of inappropriate medication use among hospitalized older adults and to identify predictors of this use. METHODS: A total of 5734 patients (mean age 79 years) admitted to geriatric and internal medicine wards participating in the study in 1995 and 1997 were included in this analysis. Inappropriate medication use was defined on the basis of the criteria published by Beers in 1997. Only medications used during hospital stay were considered for the present study. RESULTS: During hospital stay, 837 (14.6%) patients received one or more medications classified as inappropriate based on Beers criteria. Ticlopidine ( n=346; 6.0% of the study sample) was the most frequently used medication among those in Beers' list, followed by digoxin ( n=174; 3.0%) and amytriptyline ( n=113; 2.0%). The multivariate analysis showed that age [75-84 years vs 65-74 years, odds ratio (OR) 0.85, 95% confidence interval (CI) 0.71-1.00; >or=85 years vs 65-74 years, OR 0.58, 95% CI 0.46-0.73], cognitive impairment (OR 0.77, 95% CI 0.64-0.94), Charlson co-morbidity index (>or=2 vs 0-1, OR 1.20, 95% CI 1.02-1.40) and overall number of medications used during hospital stay (5-8 medications vs <5 medications, OR 2.20, 95% CI 1.72-2.82; >or=9 medications vs <5 medications, OR 3.68, 95% CI 2.86-4.73) were significantly associated with use of inappropriate medications. CONCLUSIONS: Inappropriate medication use was common among hospitalized older adults. The most important determinant of risk of receiving an inappropriate medication was the number of drugs being taken. Older age and cognitive impairment were associated with a reduced likelihood of using an inappropriate medication.

Depression and adverse drug reactions among hospitalized older adults.

BACKGROUND: Depression is a common disorder among hospitalized older adults, and it has been associated with adverse outcomes during hospital stays, including increased risk of morbidity and mortality and reduced recovery rates from illness and disability. The aim of this study was to assess whether depression may be a risk factor for adverse drug reactions (ADRs) among hospitalized older adults. METHODS: A total of 3134 older patients admitted to 23 hospitals throughout Italy between May 1 and June 30 and September 1 and October 31, 1998, entered the study. Patients with a short-form Geriatric Depression Scale score of 5 or greater were considered depressed. Adverse drug reactions observed during hospital stays and classified as definite or probable on the basis of the Naranjo algorithm were considered for this study. RESULTS: During the hospital stays, 192 ADRs were identified in 183 patients (5.8% of the sample). Cardiovascular and arrhythmic complications (20.3% of all ADRs) were the most frequent ADRs, followed by gastrointestinal (18.8%), dermatologic and allergic (12.5%), hemorrhagic (11.5%), and electrolyte (9.9%) disturbances. Adverse drug reactions were recorded in 101 (7.4%) of 1363 depressed patients and in 82 (4.6%) of 1771 nondepressed patients (P =.001). After adjusting for potential confounders, depression was associated with a significantly higher rate of ADRs (odds ratio, 1.58; 95% confidence interval, 1.14-2.20; P =.006). This effect seemed more pronounced in women (odds ratio, 1.85; 95% confidence interval, 1.16-2.95) than in men (odds ratio, 1.38; 95% confidence interval, 0.85-2.34). CONCLUSION: In older hospitalized patients, depression seems to be associated with a greater occurrence of ADRs.

Use of calcium antagonists and worsening renal function in patients receiving angiotensin-converting-enzyme inhibitors.

OBJECTIVE: The objective of this study was to assess whether calcium antagonists, which have been proven to dilate the afferent glomerular arteriole, might prevent increases in serum creatinine levels among older subjects who started treatment with angiotensin-converting enzyme (ACE) inhibitors. METHODS: We explored the association between use of calcium antagonists and incident increases in serum creatinine in 780 elderly patients with baseline creatinine levels <1.2 mg/dL (106.19 micromol/L), who were enrolled in a multicenter pharmacoepidemiology study, and who started using ACE inhibitors during their hospital stay. Among these participants, 279 also started using calcium antagonists. Demographic variables, comorbid conditions, medications, and objective tests, which were associated with increasing serum creatinine levels in separate regression models, were examined as potential confounders in a summary model. RESULTS: Among patients receiving ACE inhibitors, serum creatinine levels increased in 22% of participants who were dispensed calcium antagonists, and in 31% of other patients (P=0.005). In the summary regression model, use of calcium antagonists was associated with a decreased risk of worsening renal function (RR 0.56, 95% CI 0.37-0.84). The adjusted risk of increasing serum creatinine was lower (RR 0.25, 95% CI 0.05-0.95) in participants receiving higher calcium antagonists dosages than in those taking lower dosages. This protective effect of calcium antagonists was not detected in patients not dispensed ACE inhibitors. CONCLUSION: ACE inhibitors are underused in older subjects, mainly because of the higher incidence of renal damage among geriatric populations. Our results indicate that among elderly patients receiving ACE inhibitors, the use of calcium antagonists is associated with a reduced risk of worsening renal function. Thus, these results warrant trials aiming at establishing whether combined treatment with calcium antagonists might allow the use of ACE inhibitors in clinical practice to be expanded to the elderly population.

Nursing home case-mix instruments: validation of the RUG-III system in Italy.

BACKGROUND AND AIMS: The current Italian reimbursement system for long-term care does not adequately consider the great variability in the health and functional status of older persons who are admitted to long-term care institutions. Furthermore, no procedure is implemented to monitor the quality of care provided to older residents. We conducted this study to verify whether the RUG-III (Resource Utilization Groups-version III), a tool for assessing the case-mix of nursing home residents, which is widely used in the United States and in many European countries, can be effectively used in the Italian health care system. METHODS: We administered an Italian version of the RUG-III to 1000 older residents of 11 intermediate- and long-term care institutions. We also collected objective information on the amount of care provided directly or indirectly to each resident by nurses, physical therapists, and other health professionals. RESULTS: The RUG-III 44 group classification system explained 61 and 44% of the variance in rehabilitative and nursing wage-adjusted care time, respectively. CONCLUSIONS: Our findings provide strong evidence that the RUG-III classification, applied to Italian intermediate- and long-term care institutions, provides a robust estimate of the amount of nursing and rehabilitation resources consumed by older residents.

Effects of influenza vaccination on mortality among frail, community-living elderly patients: an observational study.

BACKGROUND AND AIMS: The annual winter outbreak of influenza is one of the major causes of morbidity and mortality among frail elderly people. The aims of the present study were to describe the prevalence of vaccination against influenza in a population of older people living in the community, and to examine the relationship between influenza vaccination and mortality. METHODS: This was an observational cohort study. We analyzed data from the Italian Silver Network Home Care project, which collected data on patients admitted to home care programs. A total of twelve Home Health Agencies participated in this project, evaluating the implementation of the Minimum Data Set for Home Care (MDS-HC) instrument. A total of 2082 patients were enrolled in the present study. The main outcome measures were prevalence of vaccination against influenza and 1-year survival according to vaccination status. RESULTS: Nearly half the subjects in our Italian sample did not receive influenza vaccination. During a mean follow-up period of 10 months from initial MDS-HC assessment, 167 vaccinated subjects (15%) died compared with 192 non-vaccinated subjects (19%) (p = 0.01). After adjusting for age, gender, and all variables significantly different between vaccinated and non-vaccinated subjects at baseline (functional and cognitive impairment, number of diseases, number of medications, depression, pressure ulcers), vaccinated subjects were less likely to die than non-vaccinated ones (RR 0.73; 95% CI 0.56-0.94). CONCLUSIONS: Vaccination against influenza has important prognostic implications for frail geriatric patients living in the community, independent of age, gender, and other clinical and functional variables. Despite extensive scientific evidence, recommendations for annual vaccination against influenza among subjects at higher risk have never been adequately implemented.

Diffuse idiopathic skeletal hyperostosis: an uncommon case of dysphagia in an older adult.

Diffuse idiopathic skeletal hyperostosis (DISH) is a common disorder among older adults. It is characterized by ossification of the anterior longitudinal ligament of the spine and various extra-spinal ligaments. Although stiffness and decreased range of motion of the spine are the most common clinical presentations of DISH, extra-skeletal manifestations may also be present. We report the case of a 65-year-old man complaining of progressive dysphagia due to DISH. Barium swallow showed compression and lateral displacement of the cervical tract of the esophagus, secondary to compression by a large osteophyte. The patient received medical treatment with COX-2 inhibitors and liquid diet. In conclusion, DISH should be considered an important, although rare, cause of dysphagia among older adults. However, it should not be accepted as the cause of dysphagia until all other causes have been ruled out.

Serum cholesterol levels and in-hospital mortality in the elderly.

PURPOSE: Although total cholesterol levels among middle-aged persons correlate with long-term mortality from all causes, this association remains controversial in older persons. We explored whether total cholesterol levels were independently associated with in-hospital mortality among elderly patients. METHODS: We analyzed data from a large collaborative observational study, the Italian Group of Pharmacoepidemiology in the Elderly (GIFA), which collected data on hospitalized patients. A total of 6984 patients aged 65 years or older who had been admitted to 81 participating medical centers during four survey periods (from 1993 to 1998) were enrolled. Patients were divided into four groups based on total cholesterol levels at hospital admission: <160 mg/dL (n = 2115), 160 to 199 mg/dL (n = 2210), 200 to 239 mg/dL (n = 1719), and >or=240 mg/dL (n = 940). RESULTS: Patients (mean [+/- SD] age, 78 +/- 7 years) were hospitalized for an average of 15 +/- 10 days. The mean total cholesterol level was 186 +/- 49 mg/dL. A total of 202 patients died during hospitalization. Mortality was inversely related to cholesterol levels (<160 mg/dL: 5.2% [110/2115]; 160-199 mg/dL: 2.2% [49/2210]; 200-239 mg/dL: 1.6% [27/1719]; and >or=240 mg/dL: 1.7% [16/940]; P for linear trend <0.001). After adjustment for potential confounders (demographic characteristics, smoking, alcohol use, indicators of nutritional status, markers of frailty, and comorbid conditions), low cholesterol levels continued to be associated with in-hospital mortality. Compared with patients who had cholesterol levels <160 mg/dL, the odds ratios for in-hospital mortality were 0.49 (95% confidence interval [CI]: 0.34 to 0.70) for participants with cholesterol levels of 160 to 199 mg/dL, 0.41 (95% CI: 0.26 to 0.65) for those with cholesterol levels of 200 to 239 mg/dL, and 0.56 (95% CI: 0.32 to 0.98) for those with cholesterol levels >or=240 mg/dL. These estimates were similar after further adjustment for inflammatory markers and after excluding patients with liver disease. CONCLUSIONS: Among older hospitalized adults, low serum cholesterol levels appear to be an independent predictor of short-term mortality.
