Background: Methenamine is a drug used for the prevention of lower urinary tract infections (UTIs). However, efficacy has not been established in older adults or patients with varying degrees of kidney function. Objective: To evaluate the effectiveness of methenamine for the prevention of UTI in adults 60 years and older. Methods: This was a retrospective, pre-post, observational study. The study included primary care patients 60 years and older who were taking methenamine between January 1, 2015, and September 30, 2018. The primary outcome was the time to first UTI after methenamine initiation compared with the average time between UTIs in the 12 months prior to methenamine initiation. Results: Of 434 patients reviewed, 150 met inclusion criteria. The average time to UTI was 3.3 months prior to methenamine initiation compared with 5.5 months after methenamine initiation ( P = 0.0004). There were 33 patients (22%) who did not have a UTI after methenamine initiation. Also, 14 patients (9.3%) had a calculated CrCl <30 mL/min at baseline. The average time to UTI in these patients was 3.3 months prior to methenamine initiation compared with 12.7 months after initiation ( P < 0.0001). Conclusion and Relevance: Methenamine use was associated with a longer time to UTI in older adults with varying degrees of kidney function. The effectiveness of methenamine appeared to be similar regardless of kidney function, which is new evidence. Because of a lack of acquired resistance, methenamine may be an effective option for UTI prophylaxis in older adults.

OBJECTIVE: Proton-pump inhibitors (PPIs) have been associated with adverse renal outcomes in older adults; however, there are little data regarding the magnitude of the change in renal function in this population. The objective of this study was to quantify the change in kidney function associated with chronic PPI therapy at two years in older adults using estimated glomerular filtration rate (eGFR).<br/> DESIGN: The study was a retrospective, pre/post, observational cohort.<br/> SETTING/PATIENTS/INTERVENTIONS/MAIN OUTCOME MEASURE(S): The study included University of Colorado Health primary care patients 60 to 89 years of age who were newly initiated on a PPI between August 1, 2012, and March 1, 2015, and remained on therapy for at least two years. The primary outcome was the change in kidney function, measured by eGFR, two years after starting PPI therapy. Secondary outcomes included change in kidney function and incidence of reduction in eGFR to < 60 mL/min/1.73 m2 two years post-index date between patients with and without diabetes mellitus.<br/> RESULTS: Of 877 electronic health records reviewed, 100 patients met inclusion criteria. The mean change in eGFR was -6.15 mL/min/1.73 m2 (standard error of the mean = 1.03) at two years compared with baseline<br/> (95% confidence interval -8.20 to -4.10; P < 0.0001). There were no differences in the secondary outcomes based on concomitant diabetes mellitus.<br/> CONCLUSIONS: Chronic PPI use was associated with a significant reduction in eGFR in ambulatory older adults at two years, beyond that expected based on increased age alone. Prescribers should be aware of the potential adverse renal effects of chronic PPI use.

Urinary tract infections (UTI) commonly occur in older adults and can lead to more severe, life-threatening infections. Physiological factors that change with age are thought to contribute to the increased frequency of UTI recurrence in older adults. Unfortunately, there are limited methods to prevent UTI in older adults, and utilization of antimicrobial agents for prevention can have many negative consequences. Methenamine has been proposed as a useful drug for the prevention of UTI as it works as a urinary antiseptic, safely producing formaldehyde to prevent bacterial growth while avoiding bacterial resistance. The objective of this review is to evaluate the existing literature and discuss the use of methenamine in older adults for prevention of UTI. A PubMed search was conducted to identify studies evaluating the effectiveness of methenamine to prevent UTI in older adults, and 10 publications were selected based on relevant criteria. Based on the literature, methenamine appears to be a safe and effective option to prevent UTI in older adults with recurrent UTI, genitourinary surgical procedures, and potentially long-term catheterization. Studies have not evaluated the safety of methenamine in patients with impaired renal function or CrCl <30 ml/min. When selecting a treatment approach to preventing UTI in older adults with adequate renal function, clinicians may consider methenamine as a viable option.

Material and methods. The study included patients (n=164) in peri- and postmenopause, having a laboratory-confirmed picture of the genitourinary menopausal syndrome - atrophic vulvovaginitis and suffering from recurrent lower urinary tract infections (UTI) - cystitis and urethritis. All patients underwent standard antibacterial therapy (ABT) UTI in accordance with the results of bacteriological urine culture according to Russian clinical guidelines on urology. Against the background of ABT, 164 patients received additional therapy with Trioginal® (the study group - SG) containing estriol, micronized progesterone and Lactobacillus casei rhamnosus Doderleini 35 (LCR 35) lactobacillus strain. Trioginal® was administered intravaginally in two stages: for 20 days, 2 capsules per day, then for 10 days, 1 capsule per day. In the comparison group - CG (n=67) with ABT, Ovipol Klio® (estriol monopreparation) was additionally intravaginally used in two stages: for 14 days, 1 suppository per day, then for 2 weeks, 1 suppository 2 times a week. The control group consisted of 30 patients receiving only standard ABT UTI, local hormone therapy for vulvovaginal atrophy (VVA) was not performed. The observation period was 12 months after the end of the course of therapy. At all stages of treatment, a subjective and objective assessment of the severity of urination disorders and urogenital atrophy (UDI-6 questionnaire), their impact on the quality of life of patients (questionnaire IIQ-7), indicators of bacteriuria, bacterial urine culture and vaginal biocenosis, frequency of undesirable phenomena were carried out. According to the initial characteristics of the group of patients were comparable. Results. At all stages of the study, in the group of patients who received therapy with the use of the Trioginal® drug, there was a significant improvement in the clinical picture of urination disorders compared to the CG and the control (main) group - MG (in SG - 18% at the end of therapy versus 100% before the start of therapy; CG - 26 % versus 100% respectively; Ledger - 58% versus 100% respectively; p

BackgroundEscherichia coli bacteraemia rates are rising with highest rates in older adults. Mandatory surveillance identifies previous Urinary Tract Infections (UTI) and catheterisation as risk factors.AimTo help control bacteraemias in older frail patients by developing a patient leaflet around the prevention and self-care of UTIs informed by the Theoretical Domains Framework.MethodFocus groups or interviews were held with care home staff, residents and relatives, GP staff and an out of hours service, public panels and stakeholders. Questions explored diagnosis, management, prevention of UTIs and antibiotic use in older adults. The leaflet was modified iteratively. Discussions were transcribed and analysed using Nvivo.ResultsCarers of older adults reported their important role in identifying when older adults might have a UTI, as they usually flag symptoms to nurses or primary care providers. Information on UTIs needs to be presented so residents can follow; larger text and coloured sections were suggested. Carers were optimistic that the leaflet could impact on the way UTIs are managed. Older adults and relatives liked that it provided new information to them. Staff welcomed that diagnostic guidance for UTIs was being developed in parallel; promoting consistent messages. Participants welcomed and helped to word sections on describing asymptomatic bacteriuria simply, preventing UTIs, causes of confusion and when to contact a doctor or nurseConclusionA final UTI leaflet for older adults has been developed informed by the TDF.

Abstract Background Pneumonia is a major cause of morbidity and mortality in older adults. The role of frailty assessment in older adults with pneumonia is not well defined. Our purpose of the study was to investigate 30-day clinical course and functional outcomes of pneumonia in older adults with different levels of frailty. Methods A prospective cohort was conducted at a university hospital in Seoul, Korea with 176 patients who were 65 years or older and hospitalized with pneumonia. A 50-item deficit-accumulation frailty index (FI) (range: 0–1; robust < 0.15, pre-frail 0.15–0.24, mild-to-moderately frail 0.25–0.44, and severely frail ≥ 0.45) and the pneumonia severity CURB-65 score (range: 0–5) were measured. Primary outcome was death or functional decline, defined as worsening dependencies in 21 daily activities and physical tasks in 30 days. Secondary outcomes were intensive care unit admission, psychoactive drug use, nasogastric tube feeding, prolonged hospitalization (length of stay > 15 days), and discharge to a long-term care institution. Results The population had a median age 79 (interquartile range, 75–84) years, 68 (38.6 %) female, and 45 (25.5 %) robust, 36 (47.4 %) pre-frail, 37 (21.0 %) mild-to-moderately frail, and 58 (33.0 %) severely frail patients. After adjusting for age, sex, and CURB-65, the risk of primary outcome for increasing frailty categories was 46.7 %, 61.1 %, 83.8 %, and 86.2 %, respectively (p = 0.014). The risk was higher in patients with frailty (FI ≥ 0.25) than without (FI < 0.25) among those with CURB-65 0–2 points (75 % vs. 52 %; p = 0.022) and among those with CURB-65 3–5 points (93 % vs. 65 %; p = 0.007). In addition, patients with greater frailty were more likely to require nasogastric tube feeding (robust vs. severe frailty: 13.9 % vs. 60.3 %) and prolonged hospitalization (18.2 % vs. 50.9 %) and discharge to a long-term care institution (4.4 % vs. 59.3 %) (p < 0.05 for all). Rates of intensive care unit admission and psychoactive drug use were similar. Conclusions Older adults with frailty experience high rates of death or functional decline in 30 days of pneumonia hospitalization, regardless of the pneumonia severity. These results underscore the importance of frailty assessment in the acute care setting.

Abstract Background There is an increase in hospital admissions for cUTI in the US despite apparent reductions in the severity of admissions. However, there are scant data on cUTI hospital admission rates from the emergency department (ED) stratified by age, infection severity, and presence of comorbidities. This study described US hospitalization patterns among adults who present to the ED with a cUTI. We sought to quantify the proportion of admissions that were potentially avoidable based on presence of sepsis and associated symtpoms as well as Charlston Comorbidity Index (CCI) scores. Methods A retrospective multi-center study using data from the Premier Healthcare Database (2013-18) was performed. Inclusion criteria: (1) age ≥ 18 years, (2) primary cUTI ED/inpatient discharge diagnosis, (3) positive blood or urine culture between index ED service days -5 to +2. Transfers from acute care facilities were excluded. Based on ICD-9/10 diagnosis codes present on admission, incidence of hospital admissions were stratified by age (≥ 65 years vs. &lt; 65 years), presence of sepsis (S), sepsis symptoms but no sepsis codes (SS) (e.g., fever, tachycardia, tachypnea, leukocytosis, etc.), and CCI. Results 187,789 patients met inclusion criteria. The mean (SD) age was 59.7 (21.9), 40.4% were male, 29.4% had sepsis, 16.7% had at least 1 SS symptom (but no S), and 53.9% had no evidence of S or SS. The median [IQR] CCI was 1 [0, 3]. 119,668 out of 187,789 (63.7%) were admitted to hospital. Among inpatients, median [IQR] length of stay (LOS) and total costs were 5 [3, 7] days and $7,956 [$4,834, $13,960] USD. Incidence of hospital admissions by age, presence of S/SS, and CCI score are shown in the Table. 18.9% of admissions (22,644/119,668) occurred in patients with no S/SS and a CCI ≤ 2. Their median [IQR] LOS and total costs were 3 [2, 5] days and $5,575 [$3,607, $9,133]. Incidence of Hospital Admission by Age, Charlson comorbidity index (CCI), Presence of Sepsis (S), and Presence of Sepsis Symptoms (SS) Conclusion Nearly 1 in 5 cUTI hospital admissions may be avoidable. Given the resources associated with the management of inpatients with cUTIs, these findings highlight the critical need for healthcare systems to develop well-defined criteria for hospital admission based on presence of comorbid conditions and infection severity. Preventing avoidable hospital admissions has the potential to save the healthcare system substantial costs. Disclosures Thomas Lodise, PharmD, PhD, Paratek Pharmaceuticals, Inc.

Abstract Introduction Older adults with cancer often require multiple medications (polypharmacy) comprising cancer-specific treatments, supportive care medications (e.g. analgesics) and medications for pre-existing conditions. The reported prevalence of polypharmacy in older adults with cancer ranges from 13–92% (1). Increasing numbers of medications pose risks of potentially inappropriate prescribing and medication non-adherence. Aim The aim of this scoping review was to provide an overview of evaluations of interventions to optimise medication prescribing and/or adherence in older adults with cancer, with a particular focus on the interventions, study populations and outcome measures that have been assessed in previous evaluations. Methods Four databases (PubMed, EMBASE, CINAHL, PsycINFO) were searched from inception to 29th November 2019 using relevant search terms (e.g. cancer, older adults, prescribing, adherence). Eligible studies evaluated interventions seeking to improve medication prescribing and/or adherence in older adults (≥65 years) with an active cancer diagnosis using a comparative evaluation (e.g. inclusion of a control group). All outcomes for studies that met inclusion criteria were included in the review. Two reviewers independently screened relevant abstracts for inclusion and performed data extraction. As a scoping review aims to provide a broad overview of existing literature, formal assessments of methodological quality of included studies were not undertaken. Extracted data were collated using tables and accompanying narrative descriptive summaries. The review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) guidelines (2). Results The electronic searches yielded 21,136 citations (Figure 1). Nine studies met inclusion criteria. Included studies consisted of five randomised controlled trials (RCTs), including one cluster RCT, and four before-and-after study designs. Studies were primarily conducted in oncology clinics, ranging from single study sites to 109 oncology clinics. Sample sizes ranged from 33 to 4844 patients. All studies had a sample population with a mean/median age of ≥65 years, however, only two studies focused specifically on older populations. Interventions most commonly involved patient education (n=6), and were delivered by pharmacists or nurses. Five studies referred to the intervention development process and no studies reported any theoretical underpinning. Three studies reported on prescribing-related outcomes and seven studies reported on adherence-related outcomes, using different terminology and a range of assessments. Prescribing-related outcomes comprised assessments of medication appropriateness (using Beers criteria), drug-related problems and drug interactions. Adherence-related outcomes included assessments of self-reported medication adherence and calculation of patients’ medication possession ratio. Conclusion The main strength of this scoping review is that it provides a broad overview of the existing literature on interventions aimed at optimising medication prescribing and adherence in older adults with cancer. The review highlights a lack of robust studies specifically targeting this patient population and limited scope to pool outcome data across included studies. Limitations of the review were that searches were restricted to English language publications and no grey literature was searched. Future research should focus specifically on older patients with cancer, and exercise rigour during intervention development, evaluation and reporting in order to generate findings that could inform future practice.
