Stall NM, Kandel C, Reppas-Rindlisbacher C, Quinn KL, Wiesenfeld L, MacFadden DR, Johnstone J, Fralick M. Antibiotics for delirium in older adults with pyuria or bacteriuria: A systematic review. J Am Geriatr Soc 2024. [PMID: 38895992 DOI: 10.1111/jgs.18964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 03/18/2024] [Accepted: 03/25/2024] [Indexed: 06/21/2024]
Abstract
BACKGROUND It is unclear whether antibiotics impact delirium outcomes in older adults with pyuria or bacteriuria in the absence of systemic signs of infection or genitourinary symptoms. METHODS We registered our systematic review protocol with PROSPERO (CRD42023418091). We searched the Medline and Embase databases from inception until April 2023 for studies investigating the impact of antimicrobial treatment on the duration and severity of delirium in older adults (≥60 years) with pyuria (white blood cells detected on urinalysis or dipstick) or bacteriuria (bacteria growing on urine culture) and without systemic signs of infection (temperature > 37.9C [>100.2F] or 1.5C [2.4F] increase above baseline temperature, and/or hemodynamic instability) or genitourinary symptoms (acute dysuria or new/worsening urinary symptoms). Two reviewers independently screened search results, abstracted data, and appraised the risk of bias. Full-text randomized controlled trials (RCTs) and observational study designs were included without restriction on study language, duration, or year of publication. RESULTS We screened 984 citations and included 4 studies comprising 652 older adults (mean age was 84.6 years and 63.5% were women). The four studies were published between 1996 and 2022, and included one RCT, two prospective observational cohort studies, and one retrospective chart review. None of the four studies demonstrated a significant effect of antibiotics on delirium outcomes, with two studies reported a worsening of outcomes among adults who received antibiotics. The three observational studies included had a moderate or serious overall risk of bias, while the one RCT had a high overall risk of bias. CONCLUSIONS Our systematic review found no evidence that treatment with antibiotics is associated with improved delirium outcomes in older adults with pyuria or bacteriuria and without systemic signs of infection or genitourinary symptoms. Overall, the evidence was limited, largely observational, and had substantial risk of bias.

Abstract
BACKGROUND Urinary tract infections (UTIs) are one of the most common infections reported in older adults, across all settings. Although a diagnosis of a UTI requires specific clinical and microbiological criteria, many older adults are diagnosed with a UTI without meeting the diagnostic criteria, resulting in unnecessary antibiotic treatment and their potential side effects, and a failure to find the true cause of their presentation to hospital. OBJECTIVE The aim of this study was to evaluate the accuracy of UTI diagnoses amongst hospitalized older adults based on clinical and microbiological findings, and their corresponding antibiotic treatment (including complications), in addition to identifying possible factors associated with a confirmed UTI diagnosis. METHODS A single-center retrospective cross-sectional study of older adult patients (n = 238) hospitalized at the University of Alberta Hospital with an admission diagnosis of UTI over a one-year period was performed. RESULTS 44.6% (n = 106) of patients had a diagnosis of UTI which was supported by documents clinical and microbiological findings while 43.3% (n = 103) of patients had bacteriuria without documented symptoms. 54.2% (n = 129) of all patients were treated with antibiotics, despite not having evidence to support a diagnosis of a UTI, with 15.9% (n = 37) of those patients experiencing complications including diarrhea, Clostridioides difficile infection, and thrush. History of major neurocognitive disorder was significantly associated with diagnosis of UTI (p = 0.003). CONCLUSION UTIs are commonly misdiagnosed in hospitalized older adults by healthcare providers, resulting in the majority of such patients receiving unnecessary antibiotics, increasing the risk of complications. These findings will allow for initiatives to educate clinicians on the importance of UTI diagnosis in an older adult population and appropriately prescribing antibiotics to prevent unwanted complications.

Abstract
One approach for improving antibiotic prescribing in nursing homes is evaluating appropriateness of initiating antibiotic therapy. However, determining appropriateness has been a challenge. To investigate this problem literature review identified studies evaluating appropriateness of initiating antibiotic therapy in nursing homes. Two criteria were used most often to assess appropriateness: infection surveillance criterion or criteria specifically designed to assist clinicians for prescribing antibiotics. Development of these criteria and results of studies using these criteria were reviewed. There was considerable variability in percentage appropriateness of initiating therapy for these criteria, variation in the methodology for conducting these studies, and limitations of the criteria. The main limitation of infection surveillance criteria is that they are specifically designed to be highly specific but this results in low sensitivity. Thus, surveillance criteria should not be used for assessing appropriateness of antibiotic therapy. The other criterion is limited because it uses only localizing signs and symptoms of infection and these findings may not be documented in the medical record when evaluating appropriateness retrospectively. Several alternative methods to assess appropriateness were identified but evaluation of these methods have not been published. Several changes are suggested to improve the evaluation of the appropriateness of initiating antibiotic therapy in nursing home residents: confirmation by the Department of Health and Human Services and the Centers for Medicare & Medicaid Services that surveillance definitions should not be used to evaluate appropriateness; develop and validate definitions of clinical infections in residents; standardize methods to evaluate appropriateness prospectively by the facility antimicrobial stewardship program; educate clinicians and nursing staff regarding the criteria for assessing appropriateness; and investigate the influence of provider-, resident-, family-, and facility-level factors on antibiotic use in nursing home residents.

Abstract
Importance There are limited data on discontinuation rates of antipsychotic medications (APMs) used to treat delirium due to acute hospitalization in the routine care of older adults. Objective To investigate discontinuation rates and patient characteristics of APMs used to treat delirium following infection-related hospitalization among older US adults. Design, Setting, and Participants This retrospective cohort study was conducted using US claims data (Optum's deidentified Clinformatics Data Mart database) for January 1, 2004, to May 31, 2022. Patients were aged 65 years or older without prior psychiatric disorders and had newly initiated an APM prescription within 30 days of an infection-related hospitalization. Statistical analysis was performed on December 15, 2022. Exposures New use (no prior use any time before cohort entry) of oral haloperidol and atypical APMs (aripiprazole, olanzapine, quetiapine, risperidone, etc). Main Outcomes and Measures The primary outcome was APM discontinuation, defined as a gap of more than 15 days following the end of an APM dispensing. Survival analyses and Kaplan-Meier analyses were used. Results Our study population included 5835 patients. Of these individuals, 790 (13.5%) were new haloperidol users (mean [SD] age, 81.5 [6.7] years; 422 women [53.4%]) and 5045 (86.5%) were new atypical APM users (mean [SD] age, 79.8 [7.0] years; 2636 women [52.2%]). The cumulative incidence of discontinuation by 30 days after initiation was 11.4% (95% CI, 10.4%-12.3%) among atypical APM users and 52.1% (95% CI, 48.2%-55.7%) among haloperidol users (P < .001 for difference between haloperidol vs atypical APMs). We observed an increasing trend in discontinuation rates from 2004 to 2022 (5% increase [95% CI, 3%-7%] per year) for haloperidol users (adjusted hazard ratio, 1.05 [1.03-1.07]; P < .001) but not for atypical APM users (1.00 [0.99-1.01]; P = .67). Prolonged hospitalization and dementia were inversely associated with the discontinuation of haloperidol and atypical APMs. Conclusions and Relevance The findings of this cohort study suggest that the discontinuation rate of newly initiated APMs for delirium following infection-related hospitalization was lower in atypical APM users than in haloperidol users, with prolonged hospitalization and dementia as major associated variables. The discontinuation rate was substantially higher in recent years for haloperidol but not for atypical APMs.

Abstract
Urinary tract infection (UTI) is common in older adults, mainly due to several age-related risk factors. Symptoms of UTI are atypical in the elderly population, like hypotension, tachycardia, urinary incontinence, poor appetite, drowsiness, frequent falls, and delirium. UTI manifests more commonly and specifically for this age group as delirium or confusion in the absence of a fever. This systematic review aims to highlight the relationship between UTI and delirium in the elderly population by understanding the pathologies individually and collectively. A systematic review is conducted by searching PubMed with regular keywords and major Medical Subject Heading (MeSH) keywords, Science Direct, and Google Scholar. The inclusion criteria consisted of studies based on male and female human populations above the age of 65 in the English language, available in full text published between 2017 and 2022. However, the exclusion criteria were animal studies, clinical trials, literature published before 2017, and papers published in any other language except English. A total of 106 articles were identified, and nine final studies were selected after a quality assessment, following which a valid relationship between delirium and UTI was identified in this systematic review.

Abstract
OBJECTIVES This paper uses deep (machine) learning techniques to develop and test how motor behaviors, derived from location and movement sensor tracking data, may be associated with falls, delirium, and urinary tract infections (UTIs) in long-term care (LTC) residents. DESIGN Longitudinal observational study. SETTING AND PARTICIPANTS A total of 23 LTC residents (81,323 observations) with cognitive impairment or dementia in 2 northeast Department of Veterans Affairs LTC facilities. METHODS More than 18 months of continuous (24/7) monitoring of motor behavior and activity levels used objective radiofrequency identification sensor data to track and record movement data. Occurrence of acute events was recorded each week. Unsupervised deep learning models were used to classify motor behaviors into 5 clusters; supervised decision tree algorithms used these clusters to predict acute health events (falls, delirium, and UTIs) the week before the week of the event. RESULTS Motor behaviors were classified into 5 categories (Silhouette score = 0.67), and these were significantly different from each other. Motor behavior classifications were sensitive and specific to falls, delirium, and UTI predictions 1 week before the week of the event (sensitivity range = 0.88-0.91; specificity range = 0.71-0.88). CONCLUSION AND IMPLICATIONS Intraindividual changes in motor behaviors predict some of the most common and detrimental acute events in LTC populations. Study findings suggest real-time locating system sensor data and machine learning techniques may be used in clinical applications to effectively prevent falls and lead to the earlier recognition of risk for delirium and UTIs in this vulnerable population.

Effect of inpatient antibiotic treatment among older adults with delirium found with a positive urinalysis: a health record review. BMC Geriatr 2022; 22:916. [PMID: 36447157 PMCID: PMC9706880 DOI: 10.1186/s12877-022-03549-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 10/20/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Among older adults with delirium and positive urinalysis, antibiotic treatment for urinary tract infection is common practice, but unsupported by literature or guidelines. We sought to: i) determine the rate of antibiotic treatment and the proportion of asymptomatic patients (other than delirium) in this patient population, and ii) examine the effect of antibiotic treatment on delirium resolution and adverse outcomes. METHODS A health record review was conducted at a tertiary academic centre from January to December 2020. Inclusion criteria were age ≥ 65, positive delirium screening assessment, positive urinalysis, and admission to general medical units. Outcomes included rates of antibiotic treatment, delirium on day 7 of admission, and 30-day adverse outcomes. We compared delirium and adverse outcome rates in antibiotic-treated vs. non-treated groups. We conducted subgroup analyses among asymptomatic patients. RESULTS We included 150 patients (57% female, mean age 85.4 years). Antibiotics were given to 86%. The asymptomatic subgroup (delirium without urinary symptoms or fever) comprised 38% and antibiotic treatment rate in this subgroup was 68%. There was no significant difference in delirium rate on day 7 between antibiotic-treated vs. non-treated groups, (entire cohort RR 0.94 [0.41-2.16] and asymptomatic subgroup RR 0.69 [0.22-2.15]) or in 30-day adverse outcomes. CONCLUSIONS Older adults with delirium and positive urinalysis in general medical inpatient units were frequently treated with antibiotics - often despite the absence of urinary or other infectious symptoms. We failed to find evidence that antibiotic treatment in this population is associated with delirium resolution on day 7 of admission.

17β-estradiol ameliorates delirium-like phenotypes in a murine model of urinary tract infection. Sci Rep 2022; 12:19622.

Abstract
Urinary tract infections (UTIs) are common and frequently precipitate delirium-like states. Advanced age coincident with the postmenopausal period is a risk factor for delirium following UTIs. We previously demonstrated a pathological role for interleukin-6 (IL-6) in mediating delirium-like phenotypes in a murine model of UTI. Estrogen has been implicated in reducing peripheral IL-6 expression, but it is unknown whether the increased susceptibility of postmenopausal females to developing delirium concomitant with UTIs reflects diminished effects of circulating estrogen. Here, we tested this hypothesis in a mouse model of UTI. Female C57BL/6J mice were oophorectomized, UTIs induced by transurethral inoculation of E. coli, and treated with 17β-estradiol. Delirium-like behaviors were evaluated prior to and following UTI and 17β-estradiol treatment. Compared to controls, mice treated with 17β-estradiol had less neuronal injury, improved delirium-like behaviors, and less plasma and frontal cortex IL-6. In vitro studies further showed that 17β-estradiol may also directly mediate neuronal protection, suggesting pleiotropic mechanisms of 17β-estradiol-mediated neuroprotection. In summary, we demonstrate a beneficial role for 17β-estradiol in ameliorating acute UTI-induced structural and functional delirium-like phenotypes. These findings provide pre-clinical justification for 17β-estradiol as a therapeutic target to ameliorate delirium following UTI.

Urinary Tract Infections Impair Adult Hippocampal Neurogenesis. BIOLOGY 2022; 11:biology11060891.

Abstract
Simple Summary Urinary tract infections are associated with features of cognitive decline and memory deficits, where the underlying correlation or mechanism is still not clear. In this study, we investigate the effect of urinary tract infections on cognitive functions in rodents and whether it is associated with adult hippocampal neurogenesis, a process that is detrimental for memory formation. We have shown that urinary tract infection affects the time spent exploring a novel arm in the Y-maze test. This was accompanied with a decrease in the proliferation of neural stem cells at an early time point post infection and a persistent decrease in neurogenesis at a later time point (34 days). We also detected decreased levels of neurotrophic factors important for neurogenesis and an elevated expression of interleukin 1β in the hippocampus. Treatment with either anti-inflammatory drugs or anti-biotics does not recover proliferation of neural stem cells. Here, we present hippocampal neurogenesis as a possible contributor to cognitive changes associated with urinary tract infections. Given the significant increase in urinary tract infection occurrence, it is important to address some of the detrimental effects that such an infection can have at the level of the brain. Abstract Previous studies have suggested a link between urinary tract infections (UTIs) and cognitive impairment. One possible contributing factor for UTI-induced cognitive changes that has not yet been investigated is a potential alteration in hippocampal neurogenesis. In this study, we aim to investigate the effect of UTI on brain plasticity by specifically examining alterations in neurogenesis. Adult male Sprague Dawley rats received an intra-urethral injection of an Escherichia coli (E. coli) clinical isolate (108 CFU/mL). We found that rats with a UTI (CFU/mL ≥ 105) had reduced proliferation of neural stem cells (NSCs) at an early time point post infection (day 4) and neurogenesis at a later time point (day 34). This was associated with the decreased expression in mRNA of BDNF, NGF, and FGF2, and elevated expression of IL-1β in the hippocampus at 6 h post infection, but with no changes in optical intensity of the microglia and astrocytes. In addition, infected rats spent less time exploring a novel arm in the Y-maze test. Treatment with an anti-inflammatory drug did not revert the effect on NSCs, while treatment with antibiotics further decreased the basal level of their proliferation. This study presents novel findings on the impact of urinary tract infections on hippocampal neurogenesis that could be correlated with cognitive impairment.

Abstract
Objective The aim of this study is to find the incidence, risks, and reasons for prolonged length of hospital stay, short, long‐term mortality, and the factors contributing to mortality of postoperative delirium in proximal femoral fractures. Methods The data for the study was obtained from National Hip Fracture Database (NHFD) and internal hospital computer systems (Medway, ICE, Clinic letters) between January 2018 and December 2019. One hundred seventy‐five patients were found have developed postoperative delirium. The outcomes measured were postoperative anemia, lower respiratory tract infection, urinary tract infection, acute kidney injury, urinary retention, cardiac event and stroke, alcohol or drug withdrawal, length of hospital stay, and 30 day and 1 year mortality. Results The patients who developed delirium were 68 (38.9%) with American Society of Anesthesiologists (ASA) grade 4 and 94 (22.3%) without delirium (p < 0.05). The average length of stay after developing postoperative delirium was 19.69 days compared to 17.4 days for patients without delirium. The mortality at 30 days and 1 year was 10.9% and 37% in patients who had postoperative delirium compared to 2.1% and 2.8% to those without delirium, respectively. Conclusion Postoperative delirium is three times more common in hip fractures. Early detection and timely management are crucial in the improvement of functional outcomes and mortality.

Abstract
OBJECTIVES Current guidelines suggest assessing non-infectious causes and careful observation before giving antibiotics to delirious patients with asymptomatic bacteriuria. Our study aims to describe the current practice of Canadian physicians regarding the investigation and treatment of asymptomatic bacteriuria in delirious older patients (aged ≥ 65 years). METHODS Our team of medical experts designed and reviewed a cross-sectional online survey. Study participants were physicians who conduct their clinical practice in Canada and care for older patients with delirium in their current practice. Potential study participants were reached through Canadian associations: Canadian Geriatrics Society, the Canadian Association of Emergency Physicians, the Association des Médecins d'Urgence du Québec and members of Choosing Wisely Canada. RESULTS 297 physicians were included. The main results show 79.4% of our participants request a urine dipstick or urinalysis in delirious patients and 52.4% immediately order a urine culture with the urinalysis. If bacteriuria is found in delirious but afebrile patients without urinary symptoms, 38% of physicians immediately treat with antibiotics, 33.8% wait for culture before initiating treatment, 14.4% treat if no other cause is found for delirium and only 13.7% would refrain from giving antibiotics. Results from respondents were similar for delirious patients with known cognitive impairment. Participants were almost unanimous (92.5%) in saying they need clear guidelines regarding the treatment of bacteriuria in older delirious patients. CONCLUSIONS This survey highlights the heterogeneous clinical management of asymptomatic bacteriuria in delirious patients and the need for clear guidelines for patients.

Abstract
OBJECTIVE This study aimed to describe prescription of antibiotics to the elderly population in general practice in Denmark from 2010-2017. DESIGN This is a national register-based observational study. SETTING General practice, Denmark. MAIN OUTCOME MEASURE The main outcome measure was prescriptions/1,000 inhabitants/day (PrID) in relation to year, age and sex, indication, and antibiotic agent. SUBJECTS In this study, we included inhabitants of Denmark, ≥65 years of age between 01st July 2010-30th June 2017. RESULTS A total of 5,168,878 prescriptions were included in the study. Antibiotic prescriptions decreased from 2.2 PrID to 1.7 (-26.9%, CI95% [-31.1;-22.4]) PrID during the study. The decrease in PrID was most noticeable among 65-74-year-olds (-25%). The ≥85-year-olds were exposed to twice as many PrID than the 65-74-year-olds, but only accounted for 20% of the total use. Urinary tract infection (UTI) was the most common indication for antibiotic prescription and increased with advancing age. The most commonly prescribed antibiotics were pivmecillinam and phenoxymethylpenicillin. Prescribing with no informative indication was present in one third of all cases. CONCLUSION The prescription of antibiotics in the elderly population in general practice decreased from 2010 to 2017. The oldest age group was exposed twice as frequently to antibiotic prescriptions as the 65-74-year-olds. The smallest reduction was observed for the ≥85-year-olds, suggesting targeting interventions at this group.Key PointsHigh antibiotic use among elderly is well known and studies indicate mis- and overuse within this population. Our study shows.The prescription rate is decreasing within all age groups of the elderly population.The ≥85-year-olds receive twice as many prescriptions/1000/day as the 65-74-years-olds.

Gestational urinary tract infections and the risk of antenatal and postnatal depressive and anxiety symptoms: A longitudinal population-based study. J Psychosom Res 2021; 150:110600. [PMID: 34547662 DOI: 10.1016/j.jpsychores.2021.110600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 05/28/2021] [Accepted: 08/14/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVE Urinary tract infections (UTIs) are among the most common bacterial infections in pregnant women. This is the first longitudinal study investigating the association between gestational UTIs and the risk of maternal antenatal and postnatal depressive and anxiety symptoms. METHODS Data were utilised from the Avon Longitudinal Study of Parents and Children (ALSPAC). Maternal depressive and anxiety symptoms during pregnancy and the postpartum period were assessed using the Edinburgh Postnatal Depression Scale (EPDS) and the Crown-Crisp Experiential Index (CCEI), respectively. We used logistic regression analyses to examine the associations using the recommended EPDS and CCEI cut-off scores. We also ran sensitivity analyses and repeated the analyses with the continuous scores. RESULTS More than 10,000 mothers had completed exposure and outcome measures during pregnancy and the postpartum period. After adjustments were made for a wide range of confounders, our findings showed that mothers with UTI during pregnancy were 1.72 (95% CI; 1.45-2.04) and 1.70 (95% CI: 1.44-1.99) times more likely to report antenatal depressive and anxiety symptoms compared with mothers without UTI, respectively. Mothers with UTI also had a 35% and a 28% higher risk of postnatal depressive symptoms at eight weeks and eight months, respectively, and the risk of postnatal anxiety was 55% higher in mothers who had UTI during pregnancy (aOR = 1.55; 95% CI, 1.26-1.91). CONCLUSIONS The present study found positive associations between UTI during pregnancy and antenatal and postnatal depressive and anxiety symptoms. Replication and further research determining the cause of these associations is warranted.

Interleukin-6 mediates delirium-like phenotypes in a murine model of urinary tract infection. J Neuroinflammation 2021; 18:247. [PMID: 34711238 PMCID: PMC8554965 DOI: 10.1186/s12974-021-02304-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Accepted: 10/20/2021] [Indexed: 01/06/2023] Open
Abstract
Background Urinary tract infection (UTI) is frequently implicated as a precipitant of delirium, which refers to an acute confusional state that is associated with high mortality, increased length of stay, and long-term cognitive decline. The pathogenesis of delirium is thought to involve cytokine-mediated neuronal dysfunction of the frontal cortex and hippocampus. We hypothesized that systemic IL-6 inhibition would mitigate delirium-like phenotypes in a mouse model of UTI. Methods C57/BL6 mice were randomized to either: (1) non-UTI control, (2) UTI, and (3) UTI + anti-IL-6 antibody. UTI was induced by transurethral inoculation of 1 × 108Escherichia coli. Frontal cortex and hippocampus-mediated behaviors were evaluated using functional testing and corresponding structural changes were evaluated via quantification of neuronal cleaved caspase-3 (CC3) by immunohistochemistry and western blot. IL-6 in the brain and plasma were evaluated using immunohistochemistry, ELISA, and RT-PCR. Results Compared to non-UTI control mice, mice with UTI demonstrated significantly greater impairments in frontal and hippocampus-mediated behaviors, specifically increased thigmotaxis in Open Field (p < 0.05) and reduced spontaneous alternations in Y-maze (p < 0.01), while treatment of UTI mice with systemic anti-IL-6 fully reversed these functional impairments. These behavioral impairments correlated with frontal and hippocampal neuronal CC3 changes, with significantly increased frontal and hippocampal CC3 in UTI mice compared to non-UTI controls (p < 0.0001), and full reversal of UTI-induced CC3 neuronal changes following treatment with systemic anti-IL-6 antibody (p < 0.0001). Plasma IL-6 was significantly elevated in UTI mice compared to non-UTI controls (p < 0.01) and there were positive and significant correlations between plasma IL-6 and frontal CC3 (r2 = 0.5087/p = 0.0028) and frontal IL-6 and CC3 (r2 = 0.2653, p < 0.0001). Conclusions These data provide evidence for a role for IL-6 in mediating delirium-like phenotypes in a mouse model of UTI. These findings provide pre-clinical justification for clinical investigations of IL-6 inhibitors to treat UTI-induced delirium.

J Am Geriatr Soc 2021; 69:3312-3323. [PMID: 34448496 PMCID: PMC9292354 DOI: 10.1111/jgs.17418] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 06/21/2021] [Accepted: 06/27/2021] [Indexed: 12/29/2022]
Abstract
Objective To determine the associations of delirium with urinary tract infection (UTI) and asymptomatic bacteriuria (AB) in individuals aged 65 and older. Methods The protocol for this systematic review and meta‐analysis was published on PROSPERO (CRD42020164341). Electronic databases were searched for relevant studies, professional associations and experts in the field were additionally contacted. Studies with control groups reporting associations between delirium and UTI as well as delirium and AB in older adults were included. The random effects model meta‐analysis was conducted using odds ratios (ORs) with 95% confidence intervals (CIs) as effect size measures. The Newcastle‐Ottawa scale was used to rate the studies' quality. Heterogeneity was assessed using the Q and I2 tests. The effects of potential moderators were investigated by both subgroup and meta‐regression analyses. The risk of publication bias was evaluated using the funnel plot and Egger's test. Results Twenty nine relevant studies (16,618 participants) examining the association between delirium and UTI in older adults were identified. The association between delirium and UTI was found to be significant (OR 2.67; 95% CI 2.12–3.36; p < 0.001) and persisted regardless of potential confounders. The association between delirium and AB in older adults in the only eligible study found (192 participants) was insignificant (OR 1.62; 95% CI 0.57–4.65; p = 0.37). All included studies were of moderate quality. Conclusion The results of this study support the association between delirium and UTI in older adults. Insufficient evidence was found to conclude on an association between delirium and AB in this age group. These findings are limited due to the moderate quality of the included studies and a lack of available research on the association between delirium and AB. Future studies should use the highest quality approaches for defining both delirium and UTI and consider AB in their investigations.

Abstract
This article critically analyses the prevalence, assessment and management of urinary tract infections (UTIs) in patients over the age of 65, in an urgent care out-of-hours service in order to enhance care. It is undertaken from the perspective of working as an Advanced Nurse Practitioner (ANP). A synopsis of UTI is presented, examining the epidemiology and aetiology. The process of assessment, diagnosis and management of UTI in older people is appraised based on current evidence. Difficulties associated with the recognition of UTI in elderly are evaluated. Finally, recommendations are made for the improvement of future practice as an ANP.

Abstract
Antibiotics are among the most common medications prescribed in nursing homes. The annual prevalence of antibiotic use in residents of nursing homes ranges from 47% to 79%, and more than half of antibiotic courses initiated in nursing-home settings are unnecessary or prescribed inappropriately (wrong drug, dose, or duration). Inappropriate antibiotic use is associated with a variety of negative consequences including Clostridioides difficile infection (CDI), adverse drug effects, drug-drug interactions, and antimicrobial resistance. In response to this problem, public health authorities have called for efforts to improve the quality of antibiotic prescribing in nursing homes.

Abstract
Bacteriuria has been associated with abnormal neurological status in humans, especially geriatric patients. In this report, we review 11 cases (seven dogs and four cats) that suggest an association between bacteriuria and abnormal neurological status in veterinary medicine. These cases showed diffuse forebrain signs with or without brainstem signs, but primary brain disease was excluded by MRI and cerebrospinal fluid analysis. Bacteriological culture of urine was positive in each animal and neurological deficits improved or resolved with initiation of antibiosis ± fluid therapy and levetiracetam. While further studies are needed to definitively confirm or refute the link between bacteriuria and a reversible encephalopathy, urine bacteriological culture should be considered in veterinary patients presented with acute onset forebrain neuro-anatomical localisation, even in the absence of clinical signs of lower urinary tract inflammation.

Abstract
Asymptomatic bacteriuria (ASB) is a common finding in many populations, including healthy women and persons with underlying urologic abnormalities. The 2005 guideline from the Infectious Diseases Society of America recommended that ASB should be screened for and treated only in pregnant women or in an individual prior to undergoing invasive urologic procedures. Treatment was not recommended for healthy women; older women or men; or persons with diabetes, indwelling catheters, or spinal cord injury. The guideline did not address children and some adult populations, including patients with neutropenia, solid organ transplants, and nonurologic surgery. In the years since the publication of the guideline, further information relevant to ASB has become available. In addition, antimicrobial treatment of ASB has been recognized as an important contributor to inappropriate antimicrobial use, which promotes emergence of antimicrobial resistance. The current guideline updates the recommendations of the 2005 guideline, includes new recommendations for populations not previously addressed, and, where relevant, addresses the interpretation of nonlocalizing clinical symptoms in populations with a high prevalence of ASB.

Reducing Antibiotic Prescriptions for Urinary Tract Infection in Nursing Homes Using a Complex Tailored Intervention Targeting Nursing Home Staff: Protocol for a Cluster Randomized Controlled Trial. JMIR Res Protoc 2020; 9:e17710. [PMID: 32383679 PMCID: PMC7244999 DOI: 10.2196/17710] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Revised: 02/27/2020] [Accepted: 02/28/2020] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND Urinary tract infection (UTI) is the most common reason for antibiotic prescription in nursing homes. Overprescription causes antibiotic-related harms in those who are treated and others residing within the nursing home. The diagnostic process in nursing homes is complicated with both challenging issues related to the elderly population and the nursing home setting. A physician rarely visits a nursing home for suspected UTI. Consequently, the knowledge of UTI and communication skills of staff influence the diagnosis. OBJECTIVE The objective of this study is to describe a cluster randomized controlled trial with a tailored complex intervention for improving the knowledge of UTI and communication skills of nursing home staff in order to decrease the number of antibiotic prescriptions for UTI in nursing home residents, without changing hospitalization and mortality. METHODS The study describes an open-label cluster randomized controlled trial with two parallel groups and a 1:1 allocation ratio. Twenty-two eligible nursing homes are sampled from the Capital Region of Denmark, corresponding to 1274 nursing home residents. The intervention group receives a dialogue tool, and all nursing home staff attend a workshop on UTI. The main outcomes of the study are the antibiotic prescription rate for UTI, all-cause hospitalization, all-cause mortality, and suspected UTI during the trial period. RESULTS The trial ended in April 2019. Data have been collected and are being analyzed. We expect the results of the trial to be published in a peer-reviewed journal in the fall of 2020. CONCLUSIONS The greatest strengths of this study are the randomized design, tailored development of the intervention, and access to medical records. The potential limitations are the hierarchy in the prescription process, Hawthorne effect, and biased access to data on signs and symptoms through a UTI diary. The results of this trial could offer a strategy to overcome some of the challenges of increased antibiotic resistance and could have implications in terms of how to handle cases of suspected UTI.

Abstract
Background Urinary tract infections (UTI) are among the most frequent bacterial infections in older adults. The aim of the study was to analyse the existence of differences in clinical features, microbiological data and risk of infection by multidrug-resistant organisms (MDRO) between older and non-older men with febrile UTI (FUTI). Methods This was an ambispective observational study involving older males with a FUTI attended in the Emergency Department. Variables collected included age, comorbidity, diagnostic of healthcare-associated (HCA)-FUTI, clinical manifestations, hospitalization, mortality, and microbiological data. Results Five hundred fifty-two males with a FUTI, 329 (59.6%) of whom were older adults, were included. Older males had a higher frequency of HCA-FUTI (p < 0.001), increased Charlson scores (p < 0.001), had received previous antimicrobial treatment more frequently (p < 0.001) and had less lower urinary tract symptoms (p < 0.001). Older patients showed a lower frequency of FUTI caused by E. coli (p < 0.001) and a higher rate of those due to Enterobacter spp. (p = 0.003) and P. aeruginosa (p = 0.033). Resistance rates to cefuroxime (p = 0.038), gentamicin (p = 0.043), and fluoroquinolones (p < 0.001) in E. coli isolates and the prevalence of extended-spectrum beta-lactamase and AmpC producing E. coli and Klebsiella spp. strains (p = 0.041) and MDRO (p < 0.001) were increased in older males. Inadequate empirical antimicrobial treatment (p = 0.004), frequency of hospitalization (p < 0.001), and all cause in-hospital mortality (p = 0.007) were higher among older patients. In the multivariate analysis, being admitted from an long term care facility (OR 2.4; 95% CI: 1.06–5.9), having a urinary tract abnormality (OR 2.2; 95% CI: 1.2–3.8) and previous antimicrobial treatment (OR 3.2; 95% CI: 1.9–5.4) were associated to FUTI caused by MDRO. Conclusions Older male adults with a FUTI have different clinical characteristics, present specific microbiological features, and antimicrobial resistance rates. In the multivariate analysis being an older male was not associated with an increased risk of FUTI caused by MDRO.

Abstract
AIMS The current definition of urinary tract infection (UTI) relies on laboratory and clinical findings, which may or may not be relevant, depending upon the patient group under consideration. This report considers the utility of current definitions for UTI in adults with and without underlying neurological conditions in order to identify gaps in current understanding and to recommend directions for research. METHODS This is a consensus report of the proceedings of Think Tank TT3: "How do we define and when do we treat UTI in neurological and non-neurological adult patients?" from the annual International Consultation on Incontinence-Research Society (ICI-RS), June 8-10, 2017 (Bristol, UK). RESULTS Evidence considering the definitions of UTI in patients with and without neurological diseases was reviewed and synthesized. We examined research on laboratory methods and clinical definitions, focusing on specific cut-off values for the quantification of significant bacteriuria, and leucocyturia. Several areas were identified, mostly related to the lack of evidence-based definitions of significant bacteriuria for different patient groups, as well as uncertainties about the role of inflammatory biomarkers, and non-specific symptoms and signs. CONCLUSIONS One of the biggest challenges in clinical practice is to discriminate between asymptomatic bacteriuria and symptomatic UTI. Future research should concentrate on risk factors for developing symptomatic UTI in different patient groups. Targeted investigations for specific populations, such as the frail elderly, and patients with neurogenic bladder dysfunction, are still needed.

Abstract
OBJECTIVE The aim of this study was to describe and characterize the prescription of antibiotics for urinary tract infection (UTI) in general practice in Denmark and to evaluate compliance with current recommendations. DESIGN National registry-based study Setting: Danish general practice Patients: 267.539 patients who redeemed a prescription for antibiotics with the clinical indication UTI at community pharmacies between July 1st 2012 and June 31st 2013. MAIN OUTCOME MEASURES Antibiotics prescribed for 1) acute lower UTI, 2) acute upper UTI and 3) recurrent UTI presented as amount of prescriptions, number of treatments per 1000 inhabitants per day (TID) and defined daily doses per 1000 inhabitants per day (DID). RESULTS A total of 507.532 prescriptions were issued to 267.539 patients during the one year study period, representing 2.35 DID. Acute lower UTI was the most common reason for prescription of antibiotics (89.5%) followed by recurrent UTI (8.4%). The majority of the prescriptions were issued to people above 60 year old (57.6%). Pivmecillinam was the most commonly prescribed antibiotic in acute lower (45.8%) and acute upper (63.3%) UTI. Trimethroprim was the most commonly prescribed antibiotic in recurrent UTI (45.9%). Prescription of quinolones increased with increasing patient-age (p = <.0001). CONCLUSION Compliance with current Danish recommendations was moderately high. Pivmecillinam is the first line antibiotic for the management of acute lower and upper UTI, and trimethroprim is the first line option of recurrent UTI. A high proportion of the antibiotic prescriptions were issued in the elderly population including a relatively high prescription rate of quinolones. Key points Urinary tract infection (UTI) is a common cause for prescription of antibiotics in general practice Poor compliance in general practice with recommendations for first-line treatment of UTI may increase antibiotic resistance Danish general practitioners are generally compliant with national and regional guidelines for antibiotic treatment of UTI There is high use of antibiotics in the elderly population including a worrisome high use of broad-spectrum antibiotics, such as Quinolones.

Mayne S, Bowden A, Sundvall PD, Gunnarsson R. The scientific evidence for a potential link between confusion and urinary tract infection in the elderly is still confusing - a systematic literature review. BMC Geriatr 2019; 19:32. [PMID: 30717706 PMCID: PMC6360770 DOI: 10.1186/s12877-019-1049-7] [Citation(s) in RCA: 43] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2017] [Accepted: 01/24/2019] [Indexed: 12/30/2022] Open
Abstract
Background Non-specific symptoms, such as confusion, are often suspected to be caused by urinary tract infection (UTI) and continues to be the most common reason for suspecting a UTI despite many other potential causes. This leads to significant overdiagnosis of UTI, inappropriate antibiotic use and potential harmful outcomes. This problem is particularly prevalent in nursing home settings. Methods A systematic review of the literature was conducted assessing the association between confusion and UTI in the elderly. PubMed, Scopus and PsychInfo were searched with the following terms: confusion, delirium, altered mental status, acute confusional state, urinary tract infection, urine infection, urinary infection and bacteriuria. Inclusion criteria and methods were specified in advance and documented in the protocol, which was published with PROSPERO (registration ID: CRD42015025804). Quality assessment was conducted independently by two authors. Data were extracted using a standardised extraction tool and a qualitative synthesis of evidence was made. Results One thousand seven hunderd two original records were identified, of which 22 were included in the final analysis. The quality of these included studies varied, with frequent poor case definitions for UTI or confusion contributing to large variation in results and limiting their validity. Eight studies defined confusion using valid criteria; however, no studies defined UTI in accordance with established criteria. As no study used an acceptable definition of confusion and UTI, an association could not be reliably established. Only one study had acceptable definitions of confusion and bacteriuria, reporting an association with the relative risk being 1.4 (95% CI 1.0–1.7, p = 0.034). Conclusions Current evidence appears insufficient to accurately determine if UTI and confusion are associated, with estimates varying widely. This was often attributable to poor case definitions for UTI or confusion, or inadequate control of confounding factors. Future well-designed studies, using validated criteria for UTI and confusion are required to examine the relationship between UTI and acute confusion in the elderly. The optimal solution to clarify this clinical issue would be a randomized controlled trial comparing the effect of antibiotics versus placebo in patients with new onset or worsening confusion and presence of bacteriuria while lacking specific urinary tract symptoms.

Abstract
This article offers strategies to help behavior analysts address medical issues which may affect behavioral intervention, beginning with the intake process and continuing through treatment and the coordination of care with other healthcare providers. The Behavior Analyst Certification Board's ethical guidelines for seeking medical consultation are reviewed. The importance of documenting clients' medical histories at intake and keeping updated medical files is emphasized. Behavioral manifestations and data patterns that may serve as red flags for medical problems are reviewed, with an emphasis on clients with limited verbal skills who cannot describe their symptoms. Multiple aspects of the behavior analyst's role in the coordination of care for clients' medical conditions are discussed.

Abstract
The diagnosis, treatment, and prevention of infectious diseases in older adults in long-term care facilities (LTCFs), particularly nursing facilities, remains a challenge for all health providers who care for this population. This review provides updated information on the currently most important challenges of infectious diseases in LTCFs. With the increasing prescribing of antibiotics in older adults, particularly in LTCFs, the topic of antibiotic stewardship is presented in this review. Following this discussion, salient points on clinical relevance, clinical presentation, diagnostic approach, therapy, and prevention are discussed for skin and soft tissue infections, infectious diarrhea (Clostridium difficile and norovirus infections), bacterial pneumonia, and urinary tract infection, as well as some of the newer approaches to preventive interventions in the LTCF setting.

Abstract
Objective: Delirium is a common neuropsychiatric syndrome in the elderly characterized by concurrent impairments in cognition and behavior. Infection is one of the most important risk factors for delirium. The objective of this study is to elaborate the factors related to the severity of delirium in the elderly patients with infection. Method: An observational study on the relationship of several clinical parameters and the severity of delirium in elderly patients (more than 60 years) with infection was conducted at Geriatric Inpatient Ward, Sanglah Hospital. Delirium was defined by the Memorial Delirium Assessment Scale (MDAS). Charlson Age Comorbidity Index (CACI) scores were calculated as proposed by Charlson et al. Infection was confirmed by clinical, laboratory, and radiographic findings. Results: During 3 months, there were 60 elderly patients (35 men and 25 women) who were hospitalized with infection and delirium. In all, 33 (55.0%), 16 (26.7%), and 11 (18.3%) patients had pneumonia, urinary tract infection, and other infections, respectively, and 44 out of 60 (73.3%) patients had sepsis. There was no significant difference found in MDAS score between male and female patients and among different types of infection, but patients with sepsis had higher MDAS score significantly compared with patients without sepsis (19.48 ± 3.72 vs. 15.88 ± 2.82; p < .001). This study revealed that of several clinical parameters, only CACI (R = .533; p < .001), blood urea nitrogen (BUN; R = .230; p = .040), and interleukin 6 (IL-6) levels (R = .499; p < .001) were correlated with MDAS score significantly. By multiple linear regression test, CACI, IL-6, and sepsis have significant role, meanwhile, BUN has no role, on the severity of delirium. Conclusions: The CACI score, IL-6 levels, and sepsis have strong relationship with the severity of delirium, but BUN only has weak role in the severity of delirium in the elderly patients with infection.

Abstract
"Urinary tract infection" ("UTI") is an ambiguous, expansive, overused diagnosis that can lead to marked, harmful antibiotic overtreatment. "Significant bacteriuria," central to most definitions of "UTI," has little significance in identifying individuals who will benefit from treatment. "Urinary symptoms" are similarly uninformative. Neither criterion is well defined. Bacteriuria and symptoms remit and recur spontaneously. Treatment is standard for acute uncomplicated cystitis and common for asymptomatic bacteriuria, but definite benefits are few. Treatment for "UTI" in older adults with delirium and bacteriuria is widespread but no evidence supports the practice, and expert opinion opposes it. Sensitive diagnostic tests now demonstrate that healthy urinary tracts host a ubiquitous, complex microbial community. Recognition of this microbiome, largely undetectable using standard agar-based cultures, offers a new perspective on "UTI." Everyone is bacteriuric. From this perspective, most people who are treated for a "UTI" would probably be better off without treatment. Elderly adults, little studied in this regard, face particular risk. Invasive bacterial diseases such as pyelonephritis and bacteremic bacteriuria are also "UTIs." Mindful decisions about antibiotic use will require a far better understanding of how pathogenicity arises within microbial communities. It is likely that public education and meaningful informed-consent discussions about antibiotic treatment of bacteriuria, emphasizing potential harms and uncertain benefits, would reduce overtreatment. Emphasizing the microbiome's significance and using the term "urinary tract dysbiosis" instead of "UTI" might also help and might encourage mindful study of the relationships among host, aging, microbiome, disease, and antibiotic treatment.

Abstract
OBJECTIVE To describe current practice around urine testing and identify factors leading to overtreatment of asymptomatic bacteriuria in community nursing homes (NHs) DESIGN Observational study of a stratified random sample of NH patients who had urine cultures ordered in NHs within a 1-month study period SETTING 31 NHs in North Carolina PARTICIPANTS 254 NH residents who had a urine culture ordered within the 1-month study period METHODS We conducted an NH record audit of clinical and laboratory information during the 2 days before and 7 days after a urine culture was ordered. We compared these results with the urine antibiogram from the 31 NHs. RESULTS Empirical treatment was started in 30% of cases. When cultures were reported, previously untreated cases received antibiotics 89% of the time for colony counts of ≥100,000 CFU/mL and in 35% of cases with colony counts of 10,000-99,000 CFU/mL. Due to the high rate of prescribing when culture results returned, 74% of these patients ultimately received a full course of antibiotics. Treated and untreated patients did not significantly differ in temperature, frequency of urinary signs and symptoms, or presence of Loeb criteria for antibiotic initiation. Factors most commonly associated with urine culture ordering were acute mental status changes (32%); change in the urine color, odor, or sediment (17%); and dysuria (15%). CONCLUSIONS Urine cultures play a significant role in antibiotic overprescribing. Antibiotic stewardship efforts in NHs should include reduction in culture ordering for factors not associated with infection-related morbidity as well as more scrutiny of patient condition when results become available.

Abstract
OBJECTIVES To explore the quality of life (QOL), perceptions, and health satisfaction of older adults with end-stage renal disease (ESRD) undergoing renal replacement therapy (RRT). DESIGN Systematic review of literature. PARTICIPANTS Individuals with ESRD undergoing RRT aged 65 and older. MEASUREMENTS Articles identified from PubMed database search from January 1994 to December 2014. The methodological quality of each of the selected articles was assessed using eight standards adapted from well-established research quality review criteria. RESULTS Of the initial 1,401 articles identified, 23 met the inclusion criteria. The age range of study participants examined was 65 to 90. Seventy-eight percent of the studies met six or more of the methodological standards; 47% found overall health-related and mental component summary QOL scores in elderly adults with ESRD to be similar to or higher than those of age-matched controls or younger individuals, although the physical component summary QOL scores tended to be lower in older adults. Only six studies addressed health satisfaction and perceptions of elderly adults with ESRD, with widely variable findings. CONCLUSION Few studies specifically examine QOL in elderly adults with ESRD undergoing RRT and even fewer address issues of perceptions and health satisfaction. However, the limited data from the QOL studies looks promising with a significant proportion showing similar or higher overall health-related and mental component summary QOL scores in elderly adults with ESRD. The very limited data on perceptions and health satisfaction of elderly adults with ESRD undergoing RRT makes it difficult to make any generalizable conclusions. Overall, more research is needed to examine these factors in elderly adults with ESRD.

Abstract
Mental disturbances have been described in patients with Parkinson's Disease (PD). Of these, the common conditions are delirium and psychosis. Delirium has been attributed to change of environment, especially hospital stay and infections; while psychosis is due to drugs like dopamine agonists. This is a case of a 75-year-old male, on levodopa therapy for PD, who presented with delirium and ended up with a cocktail diagnosis: Cryptococcal meningitis, Hashimoto's Encephalopathy (HE), Urinary tract infection with acute renal failure, Uremic encephalopathy and Levodopa induced psychosis. This case report, therefore, highlights the need to look for other causes of delirium in a patient with PD who is on levodopa therapy.

Urinary tract infections (UTIs) are among the most common bacterial infections. Although comorbid UTI in geriatric patients with delirium or dementia is well known, the prevalence and scope of the association with other neuropsychiatric disorders is unclear. We performed a systematic review of the association between UTIs and delirium, dementia, psychotic disorders, and mood disorders in hospitalized patients. We identified studies by searching PubMed, PsycInfo, and Web of Knowledge, and the reference lists of identified studies and review papers. Seventeen publications met the inclusion criteria. The primary findings were: (1) 88% of publications reported a positive association between UTIs and neuropsychiatric disorders; (2) 47% reported that the clinical course of a neuropsychiatric disorder may be precipitated or exacerbated by a UTI; (3) the mean weighted prevalence of UTIs in subjects was 19.4% for delirium, 11.2% for dementia, 21.7% for nonaffective psychotic disorders, and 17.8% for mood disorders. Our findings, which must be interpreted carefully given the heterogeneity among the studies, suggest that UTIs are highly comorbid in hospitalized patients and may precipitate or exacerbate some neuropsychiatric disorders. The association extends beyond geriatric patients with delirium, affects males and females, and includes adults with psychotic and mood disorders. These findings underscore the important interface between physical and mental health. Potential underlying mechanisms are also reviewed, including complex interactions between the immune system and the brain.

Abstract
Acute infection of the urinary tract is one of the most commonly encountered bacterial infections in the frail elderly population and is responsible for substantial morbidity and recurrent infections with antibiotic resistance. Although generally considered to be self-limiting without treatment or easily treated with a short antibiotic regime, urinary tract infections (UTIs) often have a dramatic history, associated with incomplete resolution and frequent recurrence. The biological complexity of the infections combined with a dramatic rise in antibiotic-resistant pathogens highlight the need for an anticipating strategy for therapy necessary for a rapid recovery. The first crucial step is the classification in asymptomatic bacteriuria or complicated pyelonephritis, on which the decision for the intensity of treatment and diagnostic effort is based. For the selection of empiric antibiotic therapy, knowledge about the predominant uropathogens as well as local resistance patterns is important. In this manner, most urinary tract infections in the elderly can be treated without greater expense.

Abstract
Urinary Tract Infections are common in women of all ages and the incidence increases with age. Whilst they are a common cause of lower urinary tract symptoms in all women they may be associated with increased morbidity in the elderly. Appropriate investigation and treatment in primary and secondary care are essential to effectively manage urinary tract infection and decrease morbidity and hospitalisation rates. Loss of endogenous oestrogen at the time of the menopause is associated with the urogenital atrophy and an increased incidence of urinary tract infection. Consequently vaginal oestrogen therapy may offer a rationale for treatment and prevent of urinary tract infection. The aim of this paper is to review the clinical management of elderly women presenting with primary and recurrent urinary tract infection.

Sundvall PD, Elm M, Ulleryd P, Mölstad S, Rodhe N, Jonsson L, Andersson B, Hahn-Zoric M, Gunnarsson R. Interleukin-6 concentrations in the urine and dipstick analyses were related to bacteriuria but not symptoms in the elderly: a cross sectional study of 421 nursing home residents. BMC Geriatr 2014; 14:88. [PMID: 25117748 PMCID: PMC4137105 DOI: 10.1186/1471-2318-14-88] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2014] [Accepted: 07/24/2014] [Indexed: 11/18/2022] Open
Abstract
Background Up to half the residents of nursing homes for the elderly have asymptomatic bacteriuria (ABU), which should not be treated with antibiotics. A complementary test to discriminate between symptomatic urinary tract infections (UTI) and ABU is needed, as diagnostic uncertainty is likely to generate significant antibiotic overtreatment. Previous studies indicate that Interleukin-6 (IL-6) in the urine might be suitable as such a test. The aim of this study was to investigate the association between laboratory findings of bacteriuria, IL-6 in the urine, dipstick urinalysis and newly onset symptoms among residents of nursing homes. Methods In this cross sectional study, voided urine specimens for culture, urine dipstick and IL-6 analyses were collected from all residents capable of providing a voided urine sample, regardless of the presence of symptoms. Urine specimens and symptom forms were provided from 421 residents of 22 nursing homes. The following new or increased nonspecific symptoms occurring during the previous month were registered; fatigue, restlessness, confusion, aggressiveness, loss of appetite, frequent falls and not being herself/himself, as well as symptoms from the urinary tract; dysuria, urinary urgency and frequency. Results Recent onset of nonspecific symptoms was common among elderly residents of nursing homes (85/421). Urine cultures were positive in 32% (135/421), Escherichia coli was by far the most common bacterial finding. Residents without nonspecific symptoms had positive urine cultures as often as those with nonspecific symptoms with a duration of up to one month. Residents with positive urine cultures had higher concentrations of IL-6 in the urine (p < 0.001). However, among residents with positive urine cultures there were no differences in IL-6 concentrations or dipstick findings between those with or without nonspecific symptoms. Conclusions Nonspecific symptoms among elderly residents of nursing homes are unlikely to be caused by bacteria in the urine. This study could not establish any clinical value of using dipstick urinalysis or IL-6 in the urine to verify if bacteriuria was linked to nonspecific symptoms.
