Tal S. Length of hospital stay among oldest-old patients in acute geriatric ward. Arch Gerontol Geriatr 2021; 94:104352. [PMID: 33513548 DOI: 10.1016/j.archger.2021.104352] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 01/20/2021] [Accepted: 01/21/2021] [Indexed: 01/06/2023]
Abstract
PURPOSE To examine risk factors for prolonged hospital length of stay (LOS) in the oldest-old inpatients aged ≥ 90. METHODS This retrospective cross-sectional study was performed in acute Geriatrics Department at Kaplan Medical Center. The target population was the oldest-old inpatients aged ≥ 90 hospitalized with acute illness. In total 1536 admissions of 987 patients admitted between January 2007 and December 2010 from the emergency room were included in the study. We retrieved from the electronic hospital records the following data: demographics, admission diagnosis, comorbidities, laboratory tests, drugs, functional and cognitive status, Charlson Comorbidity Index (CCI) score and age-adjusted CCI score. RESULTS The risk factors for a prolonged LOS were tube-feeding, consumption of ≥ 5 drugs, non-independent functional status, diagnosis of urinary tract infection (UTI), pneumonia and malignancy on admission, and comorbidities of congestive heart failure (CHF) and hypoalbuminemia. Multiple linear regression analysis found that UTI, hypoalbuminemia, elevated troponin, pneumonia, number of drugs, malignancy, CHF and number of comorbidities explain a higher risk for a longer LOS. CONCLUSION Hospital LOS in the oldest-old patients in acute geriatric ward was associated with admission diagnosis and comorbidities. Awareness of the risk factors for a longer LOS might contribute to reducing hospitalization stay and its related negative consequences. Accurate prediction of prolonged LOS in this age group of patients may be more challenging and require variables that were not included in our study. Future research is warranted.

Abstract
OBJECTIVES To determine if nonspecific symptoms and fever affect the posttest probability of acute bacterial infection in older patients in the emergency department (ED). DESIGN Preplanned, secondary analysis of a prospective observational study. SETTING Tertiary care, academic ED. PARTICIPANTS A total of 424 patients in the ED, 65 years or older, including all chief complaints. MEASUREMENTS We identified presence of altered mental status, malaise/lethargy, and fever, as reported by the patient, as documented in the chart, or both. Bacterial infection was adjudicated by agreement among two or more of three expert reviewers. Odds ratios were calculated using univariable logistic regression. Positive and negative likelihood ratios (PLR and NLR, respectively) were used to determine each symptom's effect on posttest probability of infection. RESULTS Of 424 subjects, 77 (18%) had bacterial infection. Accounting for different reporting methods, presence of altered mental status (PLR range, 1.40-2.53) or malaise/lethargy (PLR range, 1.25-1.34) only slightly increased posttest probability of infection. Their absence did not assist with ruling out infection (NLR, greater than 0.50 for both). Fever of 38°C or higher either before or during the ED visit had moderate to large increases in probability of infection (PLR, 5.15-18.10), with initial fever in the ED perfectly predictive, but absence of fever did not rule out infection (NLR, 0.79-0.92). Results were similar when analyzing lower respiratory, gastrointestinal, and urinary tract infections (UTIs) individually. Of older adults diagnosed as having UTIs, 47% did not complain of UTI symptoms. CONCLUSIONS The presence of either altered mental status or malaise/lethargy does not substantially increase the probability of bacterial infection in older adults in the ED and should not be used alone to indicate infection in this population. Fever of 38°C or higher is associated with increased probability of infection. J Am Geriatr Soc 67:484-492, 2019.

Abstract
Objective Urinary tract infections (UTI) are the second most common infection in geriatric population. This study investigated clinical findings, diagnostic approaches, complicating factors, prognosis, causative microorganisms and antimicrobial susceptibility in geriatric patients diagnosed with UTI. Methods A total of 140 hospitalised patients with UTIs were evaluated within three years between January 2011-January 2015 at the Eskisehir Yunus Emre State Hospital. UTI diagnosed when there were systemic and urinary signs and symptoms and a positive dipstick test and urine culture result, leukocyte and CRP like serum parameters. Results Among the studied patients, 41.4% had urological diseases, 20.7% had diabetes mellitus and 19.2% had neurological diseases. The most common symptoms and signs were fever, dysuria nausea/vomiting, general condition impairment, pyuria, haematuria. The laboratory values for CRP, ESR and leukocyte count were 84 mg/dL, 56 mm/s and 11.9 (10^3μL), with mean values being determined. Among patients having a urinary catheter (17.1%), 27.9% had a history of UTI, while 29.3% had been hospitalised. Escherichia coli and Klebsiella pneumoniae were the most commonly identified microorganisms. The mean duration for hospitalisation was 7.6 days, while a 5% mortality rate was observed over the course of the disease. Conclusion Because of the potential for serious complications and mortality, elderly patients with urinary tract infection, should receive immediate empirical treatment based on anamnesis, clinical evaluation and urinalysis and should be re-examined using results from cultures and antibiograms upon follow-up.

Abstract
Waning immunity and declining anatomic and physiologic defenses render the elder vulnerable to a wide range of infectious diseases. Clinical presentations are often atypical and muted, favoring global changes in mental status and function over febrile responses or localizing symptoms. This review encompasses early recognition, evaluation, and appropriate management of these common infections specifically in the context of elders presenting to the emergency department. With enhanced understanding and appreciation of the unique aspects of infections in the elderly, emergency physicians can play an integral part in reducing the morbidity and mortality associated with these often debilitating and life-threatening diseases.

Abstract
BACKGROUND Urinary tract infections (UTIs) are common bacterial diseases. We related diagnosis of UTIs based on International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) and in-hospital mortality (IHM) in a cohort of hospitalized elderly subjects. METHODS All patients admitted between 2000 and 2013 to the general hospital of Ferrara, in northeast Italy, with ICD-9-CM code of UTIs were included. IHM was the main outcome, and age, sex, type of microorganism, sepsis, and Charlson comorbidity index (CCI) based on ICD-9-CM, were also analyzed. RESULTS The total sample included 2,266 patients (1,670 women, 73.7%) with UTIs and identification of a cultural organism. Mean age was 81.7±7.5 years (range, 65-103). One hundred and sixteen (5.1%, of whom 34.5% were male and 65.5% were female) cases developed sepsis, and 84 (3.7%, of whom 45.2% were male, 54.8% were female) had a fatal outcome. Nonsurvivors had lower prevalence of IVUs due to Escherichia coli (53.6 vs. 71.7%, p<0.001) and higher prevalence of UTIs due to Pseudomonas aeruginosa (19 vs 7.1%, p<0.001). Moreover, non-survivors developed more frequently sepsis (31% vs. 4.1%, p<0.001), and had higher CCI (2.81±2.43 vs. 2.21±2.04, p=0.011). IHM was independently associated, in decreasing order of odds ratios (ORs), with sepsis (OR 10.3; 95% confidence interval [95% CI] 6.113-17.460, p<0.001), P. aeruginosa infection (OR 2.541; 95% CI 1.422-4.543, p=0.002), female gender (OR 2.324; 95% CI 1.480-3.650, p<0.001), CCI (OR 1.103; 95% CI 1.005-1.210, p=0.038), age (OR 1.034; 95% CI 1.002-1.066, p=0.036), and E. coli infection (OR 0.5; 95% CI 0.320-0.780, p=0.002). CONCLUSIONS In a large sample of elderly patients hospitalized for UTIs in a single center in northeastern Italy, apart the development of sepsis, IHM was much more dependent on pathogen and female gender than comorbidity index and age.

Abstract
Urea is generated by the urea cycle enzymes, which are mainly in the liver but are also ubiquitously expressed at low levels in other tissues. The metabolic process is altered in several conditions such as by diets, hormones, and diseases. Urea is then eliminated through fluids, especially urine. Blood urea nitrogen (BUN) has been utilized to evaluate renal function for decades. New roles for urea in the urinary system, circulation system, respiratory system, digestive system, nervous system, etc., were reported lately, which suggests clinical significance of urea.

Abstract
It has been suggested that mortality is higher in patients admitted to hospitals during the weekend. The objective of this study was to compare outcomes in patients with E. coli urinary tract infection (UTI) depending on the hospital admission day. For this purpose, a secondary analysis of data from a prospective cohort of patients with E. coli UTI was conducted. Weekend diagnosis of UTI was not associated with higher mortality. However, mortality was associated with sepsis, sepsis-induced hypotension and intensive care unit (ICU) admission. Sepsis-induced hypotension and ICU admission were independent determinants of mortality. The results indicate that indicators of severity of illness are associated with higher mortality in patients with UTI rather than the time of diagnosis.

Abstract
Delirium is a common and severe neuropsychiatric syndrome characterised by acute deterioration and fluctuations in mental status. It is precipitated mainly by acute illness, trauma, surgery, or drugs. Delirium affects around one in eight hospital inpatients and is associated with multiple adverse consequences, including new institutionalisation, worsening of existing dementia, and death. Patients with delirium show attentional and other cognitive deficits, altered alertness (mostly reduced, but some patients develop agitation and hyperactivity), altered sleep-wake cycle and psychoses. The pathways from the various aetiologies to the heterogeneous clinical presentations are hardly studied and are poorly understood. One of the key questions, which research is only now beginning to address, is how the factors determining susceptibility interact with the stimuli that trigger delirium. Inflammatory signals arising during systemic infection evoke sickness behaviour, a coordinated set of adaptive changes initiated by the host to respond to, and to counteract, infection. It is now clear that the same systemic inflammatory signals can have severe deleterious effects on brain function when occuring in old age or in the presence of neurodegenerative disease. Multiple animal studies now show that even mild acute systemic inflammation can induce exaggerated sickness behaviour responses and cognitive dysfunction in aged animals or those with prior degenerative pathology when compared to young and/or healthy controls. These findings appear highly promising in understanding aspects of delirium. In this review our aim is to describe and assess the parallels between exaggerated sickness behaviour in vulnerable animals and delirium in older humans. We discuss inflammatory and stress-related triggers of delirium in the context of new animal models that allow us to dissect some aspects of the mechanisms underpinning these episodes. We discuss some differences between the sickness behaviour syndrome model and delirium in the context of the complexity in the latter due to other factors such as prior pathology, psychological stress and drug effects. We conclude that, with appropriate caveats, the study of sickness behaviour in the vulnerable brain offers a promising route to uncover the mechanisms of this common and serious unmet medical need.

Abstract
An increasing number of emergency departments (EDs) are providing extended care and monitoring of patients in ED observation units (EDOUs). EDOUs can be useful for older adults as an alternative to hospitalization and as a means of risk stratification for older adults with unclear presentations. They can also provide a period of therapeutic intervention and reassessment for older patients in whom the appropriateness and safety of immediate outpatient care are unclear. This article discusses the general characteristics of EDOUs, reviews appropriate entry and exclusion criteria for older adults in EDOUs, and discusses regulatory implications of observation status for patients with Medicare.

Abstract
OBJECTIVES Current outpatient diagnostic algorithms for urinary tract infection (UTI) in older adults require the presence of classic signs and symptoms of UTI, such as fever and genitourinary symptoms. However, older adults with UTI may present with atypical signs and symptoms. The objective was to identify the associations of age and nursing home status with the clinical presentation of emergency department (ED) patients diagnosed with UTI. METHODS This was a retrospective, cross-sectional analysis of the 2001-2008 National Hospital Ambulatory Medical Care Survey (NHAMCS), ED component. Participants were adult ED patients diagnosed with UTI. Outcome variables were presence of fever, altered mental status, and urinary tract symptoms. Multivariable logistic regression models were constructed for each outcome. Age and nursing home status were the independent variables of interest. Age was divided into adults 18 to 64 years, older adults 65 to 84 years, and oldest adults 85 years of age and older. RESULTS There were 25.4 million ED visits in which UTI was diagnosed from 2001 through 2008, including 5.0 million in older adults and 2.2 million in the oldest adults. Fever was present in 13% of adults, 21% of older adults, and 19% of the oldest adults. Altered mental status was present in 1% of adults, 7% of older adults, and 13% of the oldest adults. Urinary tract symptoms were identified in 32% of adults, 24% of older adults, and 17% of the oldest adults. In multivariable analysis, altered mental status was more common in older adults (odds ratio [OR] = 1.94) and in the oldest adults (OR = 2.49). Urinary tract symptoms were less common in older adults (OR = 0.60) and the oldest adults (OR = 0.48). Nursing home residence was associated with increased fever (OR = 1.63) and altered mental status (OR = 4.79) and with decreased urinary tract symptoms (OR = 0.35). CONCLUSIONS Fever and urinary tract symptoms are absent in a large proportion of adults over 65 years of age diagnosed with UTI in the ED. Age over 65 years and nursing home residence are associated with increased presence of altered mental status and with lack of urinary tract symptoms. Nursing home residence is also associated with increased presence of fever. Emergency physicians (EPs) continue to diagnose UTI in patients without classic symptoms. Diagnostic criteria for UTI among adults 65 years and over specifically designed for use in the acute care setting should be developed and validated to prevent both inappropriate overdiagnosis and underdiagnosis of UTI.

Abstract
OBJECTIVES Older adults with infection are at increased risk of misdiagnosis while they are patients in the emergency department (ED) due to the common presence of nonspecific signs and symptoms. The primary objective was to determine the proportion of admitted older adult patients thought by the emergency physician (EP) to be infected, as compared with the diagnostic impression of inpatient physicians. The secondary objective was to determine the agreement between EP and inpatient physician diagnosis of specific infection types. METHODS The authors conducted a prospective, observational, convenience sampling of a cohort of ED patients ≥65 years old admitted to the hospital with diagnoses of acute infection. EPs noted at least one suspected source of infection. Inpatient diagnosis of infection was determined by chart review of the inpatient chart. Outcomes included the presence of any infection and of specific infectious sources diagnosed within 48 hours of admission. EP and inpatient diagnoses were compared using proportions, positive and negative likelihood ratios (LR+ and LR-), and the phi coefficient. RESULTS The study included 103 patients diagnosed with a suspected infection by the EP. Nineteen patients (18.4%, 95% confidence interval [CI] = 11.5% to 27.3%) were not diagnosed with any infection by the inpatient physician. For specific infection sources, ED diagnosis of bloodstream infection often did not agree with the inpatient diagnosis. Sensitivity was 40.0% and specificity 78.4% with an LR+ of 1.85 and LR- of 0.76. The phi coefficient was 0.15. EPs overdiagnosed pulmonary infection, with 72.1% specificity and an LR+ of 3.24. EP diagnosis had good accuracy for skin and soft tissue infection (sensitivity = 78.6% and specificity = 96.6%), with adequate LRs (LR+ of 23.3 and LR- of 0.22). Urinary tract infection (UTI) was underdiagnosed in the ED (sensitivity = 58.3%), but it is unclear if this is due to true ED underdiagnosis or due to overdiagnosis of UTI in the inpatient setting. CONCLUSIONS In older patients admitted from the ED, the provisional ED diagnosis and the inpatient diagnosis of an acute infection often disagree. In this sample, 18% of older ED patients diagnosed with infection during an ED stay were not diagnosed as infected by the inpatient physician. Regarding infection types, EPs were poor at diagnosing bacteremia and overdiagnosed pulmonary infections. EP diagnosis of skin and soft tissue infection generally agreed with the inpatient physician. There was also disagreement regarding presence of UTI, but the true nature of this difference is unclear from the data obtained in this study.

Abstract
OBJECTIVES Given reported increases in antibiotic resistance among elders with urinary tract infection (UTI) and pyelonephritis, the authors identified national rates and trends in emergency department (ED) trimethoprim-sulfamethoxazole (TMP-SMX) and fluoroquinolone prescribing for older adults from 1996 to 2005. METHODS This was a retrospective analysis utilizing the ED component of the 1996-2005 National Hospital Ambulatory Medical Care Survey (NHAMCS). The authors included NHAMCS ED entries aged >or=18 years with a diagnosis of UTI or pyelonephritis; pregnancy was excluded. Records were divided into 18-64 years ("adults") and >or=65 years ("elders"). Primary outcome measures were prescription of TMP-SMX monotherapy, fluoroquinolone monotherapy, and combination therapy with two or more antibiotics. Estimated visit totals and rates were calculated and trends analyzed. RESULTS From 1996 to 2005, there were 5 million elder ED visits for UTI or pyelonephritis. Approximately 9.4% (95% confidence interval [CI] = 7.9% to 11%) of elders received TMP-SMX monotherapy with rates decreasing over time (p-value for trend = 0.031). Overall, 35% (95% CI = 32% to 38%) of elders received fluoroquinolone monotherapy, which increased from 21% (95% CI = 14% to 27%) in 1996 to 45% (95% CI = 39% to 50%) in 2005 (p-value for trend < 0.001). Therapy with a fluoroquinolone plus a second antibiotic was used in only 4.2% (95% CI = 3.1% to 5.3%) of older patients. CONCLUSIONS From 1996 to 2005, TMP-SMX monotherapy in elder ED patients decreased while fluoroquinolone therapy increased. The majority of older patients receiving fluoroquinolone therapy received a single agent. Given the continued prevalence of monotherapy for elder ED patients with UTI or pyelonephritis, antibiotic resistance patterns in these patients should be better characterized to ensure institution of appropriate empiric therapy.

Abstract
OBJECTIVE To investigate the association between hyperglycemia and in-hospital mortality in elderly patients with Staphylococcus aureus bacteremia (SAB). METHODS We reviewed the medical records of 135 elderly patients with SAB admitted to two tertiary medical centers from January 2003 until December 2004. Patients were stratified into two groups: those with a 7-day post-SAB mean blood glucose < 170 mg/dL and those with a 7-day post-SAB mean blood glucose > or = 170 mg/dL. A stepwise logistic regression analysis was performed to determine whether the degree of hyperglycemia was a significant predictor of mortality. RESULTS Seventy-four (54.8%) patients had methicillin-resistant Staphylococcus aureus bacteremia. During the follow-up period from admission until discharge, 36 (26.7%) patients died. Twenty-one (21.4%) of 98 patients with a 7-day post-SAB mean blood glucose < 170 mg/dL died, while 15 (40.5%) of 37 patients with a 7-day post-SAB mean blood glucose > or = 170 mg/dL expired. Multivariate analysis identified 3 independent determinants of death: Simplified Acute Physiology Score (SAPS) score at onset of SAB > 45 (OR 5.3, 95% CI {1.8, 15.5}, P = 0.002), a 7-day post-SAB mean blood glucose > or = 170 mg/dL (OR 3.3, 95% CI {1.2, 9.2}, P = 0.03), and altered mental status at the onset of SAB (OR 7.8, 95% CI {2.5, 23.9}, P = 0.0003). CONCLUSIONS Hyperglycemia is an important marker of increased mortality among hospitalized elderly patients with SAB.

Abstract
As life expectancy continues to rise, the number of geriatric patients will increase and the percentages of geriatric patients seen in the emergency department will reflect those numbers. Emergency physicians are responsible for making immediate diagnoses and initiating expeditious treatment. Infectious diseases in the elderly are more prevalent, challenging to diagnose, and are associated with greater morbidity and mortality than with the younger patient population.
