Characteristics and outcome in nonagenarians admitted in general internal medicine and other specialties

[Nonagenarians on an emergency department for internal medicine and cardiology : Comparison of comorbidities, disease course and survival with younger patients]

BACKGROUND

Little is known about how younger and older hospitalized patients differ with respect to reasons for admission, comorbidities, diagnostics, treatment and intercurrent problems.

OBJECTIVE

The aim of the study was to compare the previously named characteristics in the clinical profile of patients > 90 years old (nonagenarians) with a control group of patients 70-75 years old admitted to an emergency hospital department for internal medicine and cardiology.

MATERIAL AND METHOD

The study included all consecutive nonagenarians and gender-matched control patients who were admitted during 2011. The reason for admission, comorbidities, diagnostics, treatment, intercurrent problems and discharge medication were taken from the patient records. Data on 8‑year mortality were obtained by comparison of the death data.

RESULTS

Nonagenarians (n = 117; 81 females) had a mean age of 92 ± 2.5 years and the control patients 72 ± 1.6 years. Nonagenarians were hospitalized more often because of neurological symptoms (19% vs. 7%), suffered more from kidney failure (85% vs. 67%), heart failure (35% vs. 21%), malignancies (29% vs. 8%), dementia (28% vs. 4%) and stroke (15% vs. 6%), developed confusion more often (27% vs. 7%) and fell more often (15% vs. 0%) than control patients. Control patients had a higher body mass index (29 ± 5.3 vs. 24 ± 4.1). Nonagenarians received fewer diagnostic measures (1.6 vs. 2.3), more often intravenous fluid (77% vs. 51%), diuretics (31% vs. 18%) and physiotherapy (24% vs. 8%). Polypharmacy (> 5 medications) in the discharge letter was frequent in both groups (67% vs. 75%). The yearly mortality of the nonagenarians was 27% and of the control group 6%.

CONCLUSION

Acute internal diseases in nonagenarians are frequently manifested with neurological symptoms. In hospitalized nonagenarians, prevention of falls and delirium are of clinical relevance. Polypharmacy is a relevant problem in nonagenarians as well as in control patients.

C-Reactive Protein and Albumin Levels as Useful Tools for Predicting In-Hospital Outcomes in Polish Nonagenarians

Purpose

The admissions of nonagenarians to internal medicine wards are rising. The aim of this study was to analyse the causes of ward admission and blood and renal parameters as potential mortality predictors in this age group.

Patients and Methods

Out of 1140 patients, 111 nonagenarians aged 90+ admitted to the Internal Medicine Ward in one general hospital in Poznan in 2019 were studied. Medical records of these patients were analysed to find factors attributable to the hospitalisation.

Results

The leading causes of admission were infections and cardiovascular diseases, and the main causes of death were cardiovascular diseases. Elevated C-reactive protein (CRP) level was a statistically significant death predictor. Equally, decreased albumin level was found to be a mortality predictor. No such relationships were obtained for haematological or renal parameters.

Conclusion

Our study uniquely analysed a relatively large group of hospitalised nonagenarians and identified those who need particular attention in the ward by identifying those with the highest risk of death. CRP and albumin levels may serve as useful indicators of in-hospital mortality in this age group.

Epidemiological and Clinical Features in Very Old Men and Women (≥80 Years) Hospitalized with Aortic Stenosis in Spain, 2016-2019: Results from the Spanish Hospital Discharge Database

(1) Background: The aging population poses challenges for hospital systems. Aortic stenosis is among the most frequent diseases in very old patients. The aim of this study was to describe gender and age differences in the clinical characteristics of very old patients hospitalized with aortic stenosis (AoS) in Spain from 2016 to 2019. (2): Methods: A retrospective observational study analyzing data from the national surveillance system for hospital data. Variables analyzed were age group, sex, length of stay, deaths, and comorbidity. (3) Results: The analysis included 46,967 discharges. Altogether, 7.6% of the admissions ended in death. The main reason for admission was heart failure (34.3%), and this increased with age (80−84 years: 26% versus 95−99 years: 56.6%; p < 0.001). The main treatment procedure was the transcatheter aortic valve replacement (12.7%), performed in 14.3% of patients aged 80−84 versus 0.5% in patients aged 95−99 (p < 0.001). In the multivariable analysis, women were admitted with more comorbidities (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.06−1.20). Mortality was similar, albeit women were admitted less for syncope (OR 0.83, 95% CI 0.74−0.93). Women also underwent fewer coronary catheterizations (OR 0.81, 95% CI 0.77−0.87) and echocardiograms (OR 0.96, 95% CI 0.94−0.98). (4) Conclusions: Aortic stenosis leads to a high number of hospital admissions. Women with AoS presented more heart failure and less cardiovascular pathology than men. Also, women are admitted with fewer episodes of syncope and have fewer ultrasounds and catheterizations.

Time trends in hospital discharges in patients aged 85 years and older in Spain: data from the Spanish National Discharge Database (2000-2015)

Background

The aging population is an increasing concern in Western hospital systems. The aim of this study was to describe the main characteristics and hospitalization patterns in inpatients aged 85 years or more in Spain from 2000 to 2015.

Methods

Retrospective observational study analyzing data from the minimum basic data set, an administrative registry recording each hospital discharge in Spain since 1997. We collected administrative, economic and clinical data for all discharges between 2000 and 2015 in patients aged 85 years and older, reporting results in three age groups and four time periods to assess differences and compare trends.

Results

There were 4,387,326 discharges in very elderly patients in Spain from 2000 to 2015, representing 5.32% of total discharges in 2000–2003 and 10.42% in 2012–2015. The pace of growth was faster in older age groups, with an annual percentage increase of 6% in patients aged 85–89 years, 7.79% in those aged 90–94 years, and 8.06% in those aged 95 and older. The proportion of men also rose (37.30 to 39.70%, p < 0.001).

The proportion of patients that died during hospital admission decreased from 14.64% in 2000–2003 to 13.83% in 2012–2015 (p < 0.001), and mean length of stay from 9.98 days in 2000–2003 to 8.34 days in 2012–2015.

Some of the most frequent primary diagnoses became even more frequent relative to the total number of primary diagnoses, such as heart failure (7.84 to 10.62%), pneumonia (6.36 to 7.36%), other respiratory diseases (3.87 to 8.49%) or other alterations of urinary tract (3.08 to 5.20%). However, there was a relative decrease in the proportion of femoral neck fractures (8.07 to 6.77%), neoplasms (7.65 to 7.34%), ischemic encephalopathy (6.97 to 5.85%), COPD (4.23 to 3.15%), ischemic cardiomyopathy (4.20 to 8.49%) and cholelithiasis (3.07 to 3.28%).

Conclusions

Discharges in the very elderly population are increasing in both relative and absolute terms in Spanish hospitals. Within this group, discharged patients are getting older and more frequently male. The mean length of stay and the proportion of patients that died during hospital admission are decreasing. Acute-on-chronic organ diseases, neoplasms, acute cardiovascular diseases, and infections are the most common causes of discharge.

The quick Sepsis-related Organ Failure Assessment (qSOFA) is a good predictor of in-hospital mortality in very elderly patients with bloodstream infections: A retrospective observational study

People over 80 years old are now the fastest-growing age group. Bloodstream infections (BSI) in these patients may present with specific characteristics. The objective of this study was to analyze independent factors affecting in-hospital mortality (IHM) due to BSI in very elderly patients (≥80 years of age) and to compare the clinical presentation of BSI in patients aged 80–89 years versus those aged 90 or more. Retrospective, cross-sectional and observational study of BSI in patients aged 80 years or older. The study used IHM as the primary outcome. Stepwise multiple logistic regression models were used to identify associations between potential predictors and IHM. Of the 336 included patients, 76.8% (n = 258) were in the 80–89-year age group and 23.2% (n = 78) in the 90+ age group; 17.3% (n = 58) of patients died during admission. This outcome was independently associated with quick Sepsis Related Organ Failure Assessment (qSOFA) of 2 or more (adjusted odds ratio [aOR] 4.7, 95% confidence interval [CI] 2.3–9.4; p < 0.001). Other predictors included an origin of BSI outside the urinary tract (aOR 5.5, 95% CI 2.4–12.6; p < 0.001), thrombocytopenia (aOR 4.9, 95% CI 1.8–13.4; p = 0.002), hospital-acquired infection (aOR 3.0, 95% CI 1.2–7.5; p = 0.015), and inappropriate empiric antibiotics (aOR 2.0, 95% CI 1.1–3.9; p = 0.04). IHM was 23.1% in the 90+ age group and 15.5% in patients aged 80 to 89 (p = 0.012). However, the 90+ age group was more likely to have a score of at least 2 on the qSOFA (29.9% vs. 19.1%, p = 0.043) and Pitt bacteremia scales (44.9% vs. 30.2%; p = 0.02), as well as chronic kidney disease (56.4% vs. 36.0%; p = 0.001) and altered mental state (40.3% vs. 25.7%; p = 0.013). In conclusion: A qSOFA score of 2 or more and a BSI originating outside the urinary tract were independent predictors of IHM. The 90+ age group was at higher risk than the 80–89-year age group of having a qSOFA score and Pitt bacteremia score of 2 or more as well as an altered mental state.

Functional impairment and serum albumin predict in-hospital mortality in nonagenarians with acute infection: a retrospective cohort study

Background

Acute infection leads to substantial mortality in the nonagenarian population. However, the predictive efficacies of functional status and biochemical indexes for in-hospital mortality in these patients remain to be determined.

Methods

A single-center, retrospective cohort study was performed. Consecutive nonagenarian patients who were admitted to our department from January 1, 2014 to December 31, 2016 for acute infectious diseases were included. Baseline data for medical history, functional status, and biochemical indexes were obtained on admission. The outcomes of these patients during hospitalization were recorded. Predictors of in-hospital mortality were identified via logistic regression analyses.

Results

A total of 162 patients were included, and 46 patients died (17.2%) during hospitalization. Univariate analysis showed that the prevalence rates of atrial fibrillation (32.1%) and malignant disease (26.5%) were higher in nonagenarian patients who died during hospitalization than in those who discharged. Multivariate logistic regression analyses identified malignant disease (odds ratio [OR] 2.73, 95% confidence interval [CI]: 1.10–6.78), ADL category (OR 0.82, 95% CI: 0.75–0.89) and serum albumin (OR 0.86, 95%CI 0.78–0.95) as independent predictors of in-hospital mortality in nonagenarian patients hospitalized for acute infection.

Conclusions

Functional impairment as well as serum albumin may be independent predictors of in-hospital mortality in nonagenarian patients hospitalized for acute infectious diseases. Stratification of patients according to Barthel Index score and serum albumin is very necessary.

Mortality hospital of nonagenarian patients in Internal Medicine

OBJECTIVES

To describe the predictors of hospital mortality in nonagenarian patients.

PATIENTS AND METHOD

We retrospectively studied 421 patients aged 90 years or older hospitalised in a department of internal medicine. Using logistic regression, we analysed the association between demographic, clinical and functional parameters and hospital mortality.

RESULTS

The mean age was 92.5 years (SD±2.5), and 265 (62.9%) of the patients were women. The main diagnoses were infectious diseases (257 patients, 61%) and heart failure (183, 43.5%), and the mean stay was 11.9 days (SD±8.6). During the hospitalisation, 96 patients died (22.8%). The predictors of mortality were age (P=.002), functional state (P=.006), comorbidity (P=.018) and diagnoses of pneumonia (P=.001), sepsis (P=.012) and respiratory failure (P<.001).

CONCLUSION

The hospital mortality of nonagenarian patients treated in internal medicine exceeds 20% and is associated with pneumonia, comorbidity burden and functional impairment.

Clinical and epidemiological characteristics of pyogenic liver abscess in people 65 years or older versus people under 65: a retrospective study

BACKGROUND

To analyse the clinical, epidemiological, microbiological and prognostic differences of pyogenic liver abscess (PLA) in older (≥ 65 years of age) versus younger patients (< 65 years).

METHODS

Multicentre, retrospective cohort study in all patients with PLA admitted to two Spanish hospitals from January 2000 to January 2014. Cases were divided into two age groups (< 65 years and ≥65 years) for comparison of clinical, epidemiological and microbiological characteristics as well as treatment.

RESULTS

Of 98 patients analysed, 40 patients were younger than 65, and 58 were aged 65 or older. Significant associations in the older group were found with female sex (adjusted odds ratio [ORa] 9.0; 95% CI 1.4, 56), non-cryptogenic origin (ORa 14.5; 95% CI 1.6, 129), absence of chronic liver disease (ORa 14; 95% CI 1.3, 155), Escherichia coli infection (ORa 7.7; 95% CI 1.03, 58), and incidence of complications (ORa 2.3; 95% CI 1.04, 5.4). Mortality was 8.2% overall, although all deaths occurred in the older group (8/58; 13.8%) (p = 0.02).

DISCUSSION

Our results are in consonance with other published studies. Older patients with PLA tend to present more anomalies in the biliary tract (Kai et. al, World J Gastroenterol 18: 2948-295, 2012, Rahimian et. al, Clin Infect Dis 39:1654-9, 2004, Seeto, Medicine (Baltimore) 75:99-113, 1996, Kao et.al, Aliment Pharmacol Ther 36:467-76, 2012, Lai et. al, Gastroenterology 146:129-37, 2014), while younger patients are more often male and present more commonly with previous liver disease (especially related to alcohol) and cryptogenic PLA.

CONCLUSION

In patients aged 65 or older, PLA was more common in women and in those with a history of biliary disease, and E. coli was the most frequent bacterium. Mortality was also higher in the older group.

Admissions for imported and non-imported parasitic diseases at a General Hospital in Spain: A retrospective analysis

OBJECTIVE

To analyze imported and non-imported parasitic diseases as a cause of admission to a general hospital.

METHODS

A retrospective analysis of hospital admissions for parasitic diseases between 2004 and 2013 performed by means of hospital information systems at a public hospital in the city of Castellón (Spain).

RESULTS

During the period covered in this study, there were 204,349 admissions, 213 of which were for parasitic diseases (prevalence: 1.04/1000 admission). 129 were neglected parasitic tropical diseases and 61 were imported parasitic diseases. The main parasitic diseases were hydatidosis (24.9%), visceral leishmaniasis (22.5%) and malaria (12.2%). There was a decrease in admissions for visceral leishmaniasis in the 2004-2008 period from 27.7% to 15.9% in the 2009-2013 period (p < 0.001), and an increase in admissions for malaria from 5.0% to 21.3% (p < 0.001). 38 (20.3%) of the 187 patients with parasitic diseases were HIV infected. HIV infection was more common in patients with toxoplasmosis (94.1%; p < 0.001), cryptosporidiosis (66.7%; p < 0.02) and visceral leishmaniasis (46.4%; p = 0.003). There were 34 (18.2%) children with parasitic diseases. Twelve of the 28 patients with visceral leishmaniasis (42.9%; p < 0.001), and 11 of the 17 patients with soil-transmitted diseases were children (64.7%; p < 0.001). The cause of death in eight patients was parasitic disease related (mortality rate: 4.3%). The mortality rate for visceral leishmaniasis was significantly higher (14.3%; p = 0.01).

CONCLUSION

The main cause is endemic parasitic diseases such as hydatidosis. Visceral leishmaniasis decreased during the period covered by the study, but malaria increased.

An unusual case of pancytopenia in a nonagenarian: visceral leishmaniasis

Older patients referred for further investigation of pancytopenia is common in internal medicine and geriatric clinics and it is important to consider a wide range of underlying diagnoses. We present an unusual case of febrile pancytopenia in a nonagenarian who was diagnosed with visceral leishmaniasis. This is a rare and unusual diagnosis in nonagenarians, although the leishmaniasis is endemic on the Mediterranean coast of Spain. It is important to identify it because it is treatable and curable.
