Relationship of frailty status with health resource use and healthcare costs in the population aged 65 and over in Catalonia.

BACKGROUND: Frailty is a geriatric syndrome with repercussions on health, disability, and dependency. OBJECTIVES: To assess health resource use and costs attributable to frailty in the aged population. METHODS: A population-based observational longitudinal study was performed, with follow-up from January 2018 to December 2019. Data were obtained retrospectively from computerized primary care and hospital medical records. The study population included all inhabitants aged ≥ 65 years ascribed to 3 primary care centres in Barcelona (Spain). Frailty status was established according to the Electronic Screening Index of Frailty. Health costs considered were hospitalizations, emergency visits, outpatient visits, day hospital sessions, and primary care visits. Cost analysis was performed from a public health financing perspective. RESULTS: For 9315 included subjects (age 75.4 years, 56% women), frailty prevalence was 12.3%. Mean (SD) healthcare cost in the study period was €1420.19 for robust subjects, €2845.51 for pre-frail subjects, €4200.05 for frail subjects, and €5610.73 for very frail subjects. Independently of age and sex, frailty implies an additional healthcare cost of €1171 per person and year, i.e., 2.25-fold greater for frail compared to non-frail. CONCLUSIONS: Our findings underline the economic relevance of frailty in the aged population, with healthcare spending increasing as frailty increases.

Development and validation of the electronic screening index of frailty.

BACKGROUND: primary care screening for frailty status is recommended in clinical guidelines, but is impeded by doctor and nurse workloads and the lack of valid, easy-to-use and time-saving screening tools. AIM: to develop and validate a new electronic tool (the electronic screening index of frailty, e-SIF) using routinely available electronic health data to automatically and massively identify frailty status in the population aged ≥65 years. METHODS: the e-SIF was developed in three steps: selection of clinical conditions; establishment of ICD-10 codes, criteria and algorithms for their definition; and electronic tool design and data extraction, transformation and load processes. The validation phase included an observational cohort study with retrospective data collection from computerised primary care medical records. The study population included inhabitants aged ≥65 years corresponding to three primary care centres (n = 9,315). Evaluated was the relationship between baseline e-SIF categories and mortality, institutionalisation, hospitalisation and health resource consumption after 2 years. RESULTS: according to the e-SIF, which includes 42 clinical conditions, frailty prevalence increases with age and is slightly greater in women. The 2-year adjusted hazard ratios for pre-frail, frail and very frail subjects, respectively, were as follows: 2.23 (95% CI: 1.74-2.85), 3.34 (2.44-4.56) and 6.49 (4.30-9.78) for mortality; 2.80 (2.39-3.27), 5.53 (4.59-6.65) and 9.14 (7.06-11.8) for hospitalisation; and 1.02 (0.70-1.49), 1.93 (1.21-3.08) and 2.69 (1.34-5.40) for institutionalisation. CONCLUSIONS: the e-SIF shows good agreement with mortality, institutionalisation, hospitalisation and health resource consumption, indicating satisfactory validity. More studies in larger populations are needed to corroborate our findings.

Prevalence, Risk Factors, and Complications of Oropharyngeal Dysphagia in Older Patients with Dementia.

The prevalence of older patients with dementia and oropharyngeal dysphagia (OD) is rising and management is poor. Our aim was to assess the prevalence, risk factors, and long-term nutritional and respiratory complications during follow-up of OD in older demented patients. We designed a prospective longitudinal quasi-experimental study with 255 patients with dementia. OD was assessed with the Volume-Viscosity Swallowing Test and a geriatric evaluation was performed. OD patients received compensatory treatments based on fluid viscosity and texture modified foods and oral hygiene, and were followed up for 18 months after discharge. Mean age was 83.5 ± 8.0 years and Alzheimer's disease was the main cause of dementia (52.9%). The prevalence of OD was 85.9%. Up to 82.7% patients with OD required fluid thickening and 93.6% texture modification, with poor compliance. OD patients were older (p < 0.007), had worse functionality (p < 0.0001), poorer nutritional status (p = 0.014), and higher severity of dementia (p < 0.001) than those without OD and showed higher rates of respiratory infections (p = 0.011) and mortality (p = 0.0002) after 18 months follow-up. These results show that OD is very prevalent among patients with dementia and is associated with impaired functionality, malnutrition, respiratory infections, and increased mortality. New nutritional strategies should be developed to increase the compliance and therapeutic effects for this growing population of dysphagic patients.

Intracellular Water Content in Lean Mass is Associated with Muscle Strength, Functional Capacity, and Frailty in Community-Dwelling Elderly Individuals. A Cross-Sectional Study.

High intracellular water (ICW) content has been associated with better functional performance and a lower frailty risk in elderly people. However, it is not clear if the protective effect of high ICW is due to greater muscle mass or better muscle quality and cell hydration. We aimed to assess the relationship between ICW content in lean mass (LM) and muscle strength, functional performance, frailty, and other clinical characteristics in elderly people. In an observational cross-sectional study of community-dwelling subjects aged ≥75 years, ICW and LM were estimated by bioelectrical impedance, and the ICW/LM ratio (mL/kg) calculated. Muscle strength was measured as hand grip, frailty status was assessed according to Fried criteria, and functional status was assessed by Barthel score. For 324 recruited subjects (mean age 80 years), mean (SD) ICW/LM ratio was 408 (29.3) mL/kg. The ICW/LM ratio was negatively correlated with age (rs = -0.249; p < 0.001). A higher ICW/LM ratio was associated with greater muscle strength, better functional capacity, and a lower frailty risk, even when adjusted by age, sex, nº of co-morbidities, and LM. ICW content in LM (including the muscle) may influence muscle strength, functional capacity and frailty. However, further studies are needed to confirm this hypothesis.

Hospitalizaciones evitables por reacciones adversas a medicamentos en una unidad geriátrica de agudos. Análisis de 3.292 pacientes / Avoidable hospitalizations due to adverse drug reactions in an acute geriatric unit. Analysis of 3, 292 patients

Objetivo: Determinar la prevalencia de ingresos por reacciones adversas a medicamentos (RAM) y si el ingreso era evitable o no, y qué fármacos y factores de riesgo estaban implicados. Diseño: Estudio observacional transversal. Muestra de estudio Todos los pacientes hospitalizados en una unidad geriátrica de agudos durante el período de enero de 2001 a diciembre de 2010 fueron estudiados. Mediciones: Para determinar si los ingresos se debieron a RAM se utilizaron los criterios de la World Health Organization-Uppsala Monitoring Centre y la escala de Naranjo. Para detectar los medicamentos potencialmente inadecuados se utilizaron los criterios de Beers. Resultados: Se estudió un total de 3.292 pacientes (edad media 84,7 años, 60,1% mujeres). De estos, 197 (6%) fueron ingresos por RAM, de los cuales 152 (76,4%) se consideraron ingresos evitables. Los 5 grupos de fármacos más frecuentemente asociados a los ingresos por RAM fueron digoxina, antiinflamatorios no esteroideos, benzodiacepinas, diuréticos y antibióticos. Los factores de riesgo independientes de ingreso por RAM fueron el sexo femenino (OR 1,84; IC 95% 1,3-2,61), la medicación inadecuada según los criterios de Beers (OR 4,2; IC 95% 2,9-6,03), la polifarmacia (>5 fármacos) (OR 1,5; IC 95% 1,04-2,13), el filtrado glomerular<30ml/min (OR 3; IC 95% 2,12-4,23) y el uso de sedantes (OR 1,4; IC 95% 1-1,91). Conclusión: Las RAM fueron responsables del 6% de los ingresos en una unidad geriátrica de agudos, considerándose evitables tres cuartas partes de estos ingresos. El sexo femenino, la medicación inadecuada, la polifarmacia, la insuficiencia renal y el uso de sedantes fueron factores de riesgo independientes de ingreso por RAM (AU)

Objective: To determine prevalence of admissions due to an adverse drug reaction (ADR) and determine whether or not admission was avoidable, and what drugs and risk factors were implicated. Design: Cross-sectional observational study. Study sample: All patients hospitalized in an acute geriatric unit during the period January 2001 to December 2010 were studied. Measurement: To determine whether admissions were due toADR, we used the World Health Organization-Uppsala Monitoring Centre criteria and the Naranjo scale. Beers criteria were used to detect potentially inappropriate medication. Results: A total of 3,292 patients (mean age 84.7 years, 60.1% women) were studied. Of these, 197 (6%) were admissions for ADR and nearly three quarters (76.4%, 152 cases) were considered avoidable admissions. The 5 most frequent drugs associated with admissions for ADR were digoxin, nonsteroidal anti-inflammatory drugs, benzodiazepines, diuretics and antibiotics. Independent risk factors for admissions for ADR were being female (OR 1.84; 95% CI 1.30-2.61), inappropriate medication according to Beers criteria (OR 4.20; 95% CI 2.90-6.03), polypharmacy (>5 drugs) (OR 1.50; 95% CI 1.04-2.13), glomerular filtration rate<30mL/min (OR 3; 95% CI 2.12-4.23) and sedative use (OR 1.40; 95% CI 1-1.91). Conclusion: ADR were responsible for 6% of admissions to an acute geriatric unit, and over 75% of these admissions were considered avoidable. Associated risk factors were being female, inappropriate medication, polypharmacy, renal insufficiency and sedative use (AU)

Randomized controlled trial of an intervention to improve drug appropriateness in community-dwelling polymedicated elderly people.

BACKGROUND: Polypharmacy is frequent in the elderly population and is associated with potentially drug inappropriateness and drug-related problems. OBJECTIVES: To assess the effectiveness and safety of a medication evaluation programme for community-dwelling polymedicated elderly people. DESIGN: Randomized, open-label, multicentre, parallel-arm clinical trial with 1-year follow-up. SETTING: Primary care centres. PARTICIPANTS: Polymedicated (≥8 drugs) elderly people (≥70 years). STUDY INTERVENTION: Pharmacist review of all medication according to the Good Palliative-Geriatric Practice algorithm and the Screening Tool of Older Person's Prescriptions-Screening Tool to Alert Doctors to the Right Treatment criteria and recommendations to the patient's physician. CONTROL INTERVENTION: Routine clinical practice. MEASUREMENTS: Recommendations and changes implemented, number of prescribed drugs, restarted drugs, primary care and emergency department consultations, hospitalizations and death. RESULTS: About 503 (252 intervention and 251 control) patients were recruited and 2709 drugs were evaluated. About 26.5% of prescriptions were rated as potentially inappropriate and 21.5% were changed (9.1% discontinuation, 6.9% dose adjustment, 3.2% substitution and 2.2% new prescription). About 2.62 recommendations per patient were made and at least one recommendation was made for 95.6% of patients. The mean number of prescriptions per patient was significantly lower in the intervention group at 3- and 6-month follow-up. Discontinuations, dose adjustments and substitutions were significantly higher than in the control group at 3, 6 and 12 months. No differences were observed in the number of emergency visits, hospitalizations and deaths. CONCLUSION: The study intervention was safe, reduced potentially inappropriate medication, but did not reduce emergency visits and hospitalizations in polymedicated elderly people.

Nutritional status of older patients with oropharyngeal dysphagia in a chronic versus an acute clinical situation.

BACKGROUND: Oropharyngeal dysphagia (OD) is a prevalent risk factor for malnutrition (MN) in older patients and both conditions are related to poor outcome. OBJECTIVE: To explore the nutritional status in older patients with OD in a chronic and an acute clinical situation. DESIGN: We examined 95 older (≥70 years) patients with OD associated to chronic neurological diseases or aging, and 23 older patients with OD and acute community-acquired pneumonia (CAP) with videofluoroscopy; and 15 older people without OD. We collected nutritional status, measured with the Mini Nutritional Assessment (MNA®), anthropometric measurements, and biochemistry and bioimpedance for body composition. Functional status was assessed with the Barthel index. RESULTS: 1) Taking into consideration patients with OD with chronic conditions, 51.1% presented a MNA® ≤23.5; 16.7%, sarcopenia and a) reduced visceral and muscular protein compartments and fat compartment; b) muscular weakness c) intracellular water depletion, and d) reduced body weight. Patients with OD and MNA® ≤23 needed higher levels of nectar viscosity for a safe swallow and had increased oropharyngeal residue at spoon-thick viscosity. 2) Patients with OD and CAP, 69.5%, presented an MNA® ≤23.5 and 29.4% sarcopenia, the inflammatory response of the pneumonia adding to the more severe depletion in visceral protein and muscular mass. CONCLUSIONS: Prevalence of impaired nutritional status (malnutrition risk, and sarcopenia) among older patients with OD associated with either chronic or acute conditions is very high. In patients with OD and chronic diseases, poor nutritional status further impairs OD with an increase in oropharyngeal residue at spoon-thick viscosity. In the acute setting there is inflammation and an additional protein deficiency. These findings will help develop specific products both for OD and nutritional status in each specific clinical situation.

Drugs Related to Oropharyngeal Dysphagia in Older People.

Scientific evidence on the impact of medication on the physiology of swallowing is scarce and mainly based on clinical case reports. To evaluate the association between oropharyngeal dysphagia (OD) and chronic exposure to medication in older patients admitted to the acute geriatric unit (AGU) of a secondary hospital, we performed a retrospective cross-sectional study of 966 patients admitted to an AGU from 2008 to 2011. We reviewed (a) diagnosis of OD (assessed with the volume-viscosity swallow test, V- VST); (b) chronic patient medication classified by anatomical, therapeutic, chemical codes; and (c) demographic and clinical data. A univariate analysis was performed to determine which medications were associated with OD. A multivariate analysis adjusting for confounding clinical factors was performed to identify which of those medications were independently associated with OD. The age of patients included was 85.3 ± 6.37 years and 59.4 % were women. A total of 41.9 % presented OD. We found a possible protective effect of beta blocking agents on OD after the multivariate analysis (OR 0.54, 95 % CI 0.35-0.85). None of the categories of drugs was associated with an altered swallowing function after adjusting for confounding variables. The present study is the first one to widely investigate the association between drugs and OD, increasing understanding of their association. The role of beta blockers in OD needs to be further studied as their potentially beneficial effects on the swallowing function in older patients could help to prevent complications.

Oropharyngeal dysphagia is a prevalent risk factor for malnutrition in a cohort of older patients admitted with an acute disease to a general hospital.

BACKGROUND & AIMS: Oropharyngeal dysphagia and malnutrition are prevalent conditions in the older. The aim of this study was to explore the relationship between oropharyngeal dysphagia, nutritional status and clinical outcome in older patients admitted to an acute geriatric unit. METHODS: We studied 1662 patients ≥70 years consecutively hospitalized with acute diseases, in whom dysphagia could be clinically assessed by the volume-viscosity swallow test and nutritional status with the Mini Nutritional Assessment(®). Anthropometric and laboratory measurements were taken and mortality recorded during hospital stay, at 6 months and one year after discharge was recorded. RESULTS: 47.4% (95% CI 45-49.8%) patients presented oropharyngeal dysphagia and 30.6% (95% CI 27.9%-33.3%), malnutrition. Both conditions were associated with multimorbidity, multiple geriatric syndromes and poor functional capacity (p < 0.001). However, patients with dysphagia presented increased prevalence of malnutrition (MNA(®) < 17 45.3% vs 18%, p < 0.001) regardless of their functional status and comorbidities (OR 2.31 (1.70-3.14)) and lower albumin and cholesterol levels. Patients with malnutrition presented an increased prevalence of dysphagia (68.4% (95% CI 63.3-73.4)). Patients with dysphagia and patients with malnutrition presented increased intrahospital, 6-month and 1-year mortality rates (p < 0.05). The poorest outcome was for patients with both conditions (1-year mortality was 65.8%). CONCLUSIONS: Prevalence of dysphagia was higher than malnutrition in our older patients. Dysphagia was an independent risk factor for malnutrition, and both conditions were related to poor outcome.

Oropharyngeal dysphagia is a risk factor for readmission for pneumonia in the very elderly persons: observational prospective study.

BACKGROUND: To determine whether oropharyngeal dysphagia is a risk factor for readmission for pneumonia in elderly persons discharged from an acute geriatric unit. METHODS: Observational prospective cohort study with data collection based on clinical databases and electronic clinical notes. All elderly individuals discharged from an acute geriatric unit from June 2002 to December 2009 were recruited and followed until death or December 31, 2010. All individuals were initially classified according to the presence of oropharyngeal dysphagia assessed by bedside clinical examination. Main outcome measure was readmission for pneumonia. Clinical notes were reviewed by an expert clinician to verify diagnosis and classify pneumonia as aspiration or nonaspiration pneumonia. RESULTS: A total of 2,359 patients (61.9% women, mean age 84.9 y) were recruited and followed for a mean of 24 months. Dysphagia was diagnosed in 47.5% of cases. Overall, 7.9% of individuals were readmitted for pneumonia during follow-up, 24.2% of these had aspiration pneumonia. The incidence rate of hospital readmission for pneumonia was 3.67 readmissions per 100 person-years (95% CI 3.0-4.4) in individuals without dysphagia and 6.7 (5.5-7.8) in those with dysphagia, with an attributable risk of 3.02 readmissions per 100 person-years (1.66-4.38) and a rate ratio of 1.82 (1.41-2.36). Multivariate Cox regression showed an independent effect of oropharyngeal dysphagia, with a hazard ratio of 1.6 (1.15-2.2) for hospitalization for pneumonia, 4.48 (2.01-10.0) for aspiration pneumonia, and 1.44 (1.02-2.03) for nonaspiration pneumonia. CONCLUSION: Oropharyngeal dysphagia is a very prevalent and relevant risk factor associated with hospital readmission for both aspiration and nonaspiration pneumonia in the very elderly persons.

Complications of oropharyngeal dysphagia: aspiration pneumonia.

The incidence and prevalence of aspiration pneumonia (AP) are poorly defined. They increase in direct relation with age and underlying diseases. The pathogenesis of AP presumes the contribution of risk factors that alter swallowing function and predispose to the oropharyngeal bacterial colonization. The microbial etiology of AP involves Staphylococcus aureus, Haemophilus influenzae and Streptococcus pneumoniae for community-acquired AP and Gram-negative aerobic bacilli in nosocomial pneumonia. It is worth bearing in mind the relative unimportance of anaerobic bacteria in AP. When we choose the empirical antibiotic treatment, we have to consider some pathogens identified in oropharyngeal flora. Empirical treatment with antianaerobics should only be used in certain patients. According to some known risks factors, the prevention of AP should include measures in order to avoid it.

Pathophysiology, relevance and natural history of oropharyngeal dysphagia among older people.

Oropharyngeal dysphagia (OD) is a very frequent condition among older people with a prevalence ranging from mild symptoms in 25% of the independently living to severe symptoms in more than 50% living in nursing homes. There are several validated methods of screening, and clinical assessment and videofluoroscopy are the gold standard for the study of the mechanisms of OD in the elderly. Oropharyngeal residue is mainly caused by weak bolus propulsion forces due to tongue sarcopenia. The neural elements of swallow response are also impaired in older persons, with prolonged and delayed laryngeal vestibule closure and slow hyoid movement causing oropharyngeal aspirations. OD causes malnutrition, dehydration, impaired quality of life, lower respiratory tract infections, aspiration pneumonia, and poor prognosis including prolonged hospital stay and enhanced morbidity and mortality in several phenotypes of older patients ranging from independently living older people, hospitalized older patients and nursing home residents. Enhancing bolus viscosity of fluids greatly improves safety of swallow in all these patients. We believe OD should be recognized as a major geriatric syndrome, and we recommend a policy of systematic and universal screening and assessment of OD among older people to prevent its severe complications.

Diagnosis and management of oropharyngeal Dysphagia and its nutritional and respiratory complications in the elderly.

Oropharyngeal dysphagia is a major complaint among older people. Dysphagia may cause two types of complications in these patients: (a) a decrease in the efficacy of deglutition leading to malnutrition and dehydration, (b) a decrease in deglutition safety, leading to tracheobronchial aspiration which results in aspiration pneumonia and can lead to death. Clinical screening methods should be used to identify older people with oropharyngeal dysphagia and to identify those patients who are at risk of aspiration. Videofluoroscopy (VFS) is the gold standard to study the oral and pharyngeal mechanisms of dysphagia in older patients. Up to 30% of older patients with dysphagia present aspiration-half of them without cough, and 45%, oropharyngeal residue; and 55% older patients with dysphagia are at risk of malnutrition. Treatment with dietetic changes in bolus volume and viscosity, as well as rehabilitation procedures can improve deglutition and prevent nutritional and respiratory complications in older patients. Diagnosis and management of oropharyngeal dysphagia need a multidisciplinary approach.

Prevalence and prognostic implications of dysphagia in elderly patients with pneumonia.

BACKGROUND: oropharyngeal dysphagia is a common condition among the elderly but not systematically explored. OBJECTIVE: to assess the prevalence and the prognostic significance of oropharyngeal dysphagia among elderly patients with pneumonia. DESIGN: a prospective cohort study. SETTING: an acute geriatric unit in a general hospital. SUBJECTS: a total of 134 elderly patients (>70 years) consecutively admitted with pneumonia. METHODS: clinical bedside assessment of oropharyngeal dysphagia and aspiration with the water swallow test were performed. Demographic and clinical data, Barthel Index, Mini Nutritional Assessment, Charlson Comorbidity Index, Fine's Pneumonia Severity Index and mortality at 30 days and 1 year after admission were registered. RESULTS: of the 134 patients, 53% were over 84 years and 55% presented clinical signs of oropharyngeal dysphagia; the mean Barthel score was 61 points indicating a frail population. Patients with dysphagia were older, showed lower functional status, higher prevalence of malnutrition and comorbidities and higher Fine's pneumonia severity scores. They had a higher mortality at 30 days (22.9% vs. 8.3%, P = 0.033) and at 1 year of follow-up (55.4% vs. 26.7%, P = 0.001). CONCLUSIONS: oropharyngeal dysphagia is a highly prevalent clinical finding in elderly patients with pneumonia and is an indicator of disease severity in older patients with pneumonia.

Functional status as a risk factor for mortality in very elderly patients with pneumonia.

BACKGROUND AND OBJECTIVE: The most commonly used prognostic mortality indexes for pneumonia take into account several variables including comorbidities, physical examination results, and laboratory test results, as well as age. Other factors such as functional status are not included. The objective of this study was to know whether the preadmission functional status was related to 30-day mortality in old or very old patients who were hospitalized for pneumonia. PATIENTS AND METHOD: This was a prospective study including all patients who were hospitalized for pneumonia in the Acute Geriatric Unit of Hospital de Mataró, Barcelona. We calculated the Pneumonia Severity Index (PSI), preadmission and admission Barthel Index (BI), Charlson Comorbidity Index and Mini Nutritional Assessment (MNA). Patients were assessed during hospitalisation and until death or 30 days after admission. RESULTS: We studied 117 patients, 69 (59%) were men. The mean age (standard deviation) was 84.7 (6.5) years. The 30-day mortality was 16.2%. The PSI score was 134.2 (31.8) on admission, and the BI scores on preadmission and admission were 60.3 (35.8) and 37.1 (33.5), respectively. In a multiple logistic regression model, using all variables statistically significant in the univariate analysis, those independently associated with 30-day mortality were: preadmission BI lower than 60 points (odds ratio = 4.89; 95% confidence interval, 1.27-18.9) and lymphopenia (odds ratio = 7.11; 95% confidence interval, 1.7-30.2). CONCLUSIONS: In very old patients who were hospitalized for pneumonia, preadmission functional status was an independent predictor of mortality. Functional status should be included in the severity indices of pneumonia in this population.
