Skip The Dip For Urinary Tract Infection in over 65s. A National Initiative To Reduce Antibiotic Prescribing In Older Persons

Abstract Background Urinary tract infection (UTI) is the most common reason for antibiotic use in older persons in residential care. Dipstick urinalysis for UTI is an ingrained practice. Inappropriate use of dipstick urinalysis can lead to inappropriate antibiotic prescribing, contributing to adverse effects and antimicrobial resistance. The ‘Skip the Dip for UTI in over 65s’ quality improvement initiative (QI) aims to raise awareness of best practice for diagnosis and management of suspected UTI to reduce unnecessary antibiotic use. It supports implementation of national guidance stating dipstick urinalysis is not recommended for assessment of evidence of UTI in people 65 years and over. Methods Focus groups with nursing staff in older persons residential care facilities (OPRCFs) identified barriers and facilitators for implementing national guidance on dipstick urinalysis for UTI. Supporting resources developed included a resident leaflet on UTI, staff handbook and webinar recording, hosted on www.antibioticprescribing.ie. Antimicrobial pharmacists delivered workshops on improving assessment of suspected UTI in the HSE OPRCFs from September 2023 to March 2024. Monthly monitoring of antibiotic use for UTI was established in all 119 HSE OPRCFs. Surveys to establish dipstick urinalysis practice in the OPRCFs were administered in March 2023 and March 2024. Results A baseline survey in 2020/21 indicated 98% HSE OPRCFs (133/135) performed dipstick urinalysis for residents with symptoms of UTI, reducing to 53% (57/107) in March 2023, and 24% (25/103) in March 2024 following this QI. Prevalence of antibiotics for treatment of UTI in the HSE OPRCFs decreased by 38%, from a baseline of 2.6% (114/4,446 residents) in 2020/21, to 1.6% (66/4,222 residents) in March 2024. Conclusion The ‘Skip the Dip for UTI in over 65s’ QI has resulted in a change in practice, with the majority of HSE OPRCFs now reporting dipstick urinalysis is not performed for UTI assessment, with a considerable reduction in antibiotics prescribed for UTIs.

Knowledge attitude and practice of antibiotic use among medical students in Bangladesh: A cross-sectional study.

Antibiotic misuse represent a significant global health challenge, with medical students positioned as key figures in promoting responsible antibiotic usage. This study investigates the knowledge, attitudes, and practices (KAP) regarding antibiotic use among medical students in Bangladesh, aiming to identify areas for targeted educational and policy interventions. This cross-sectional survey was conducted among 501 medical students across various years of study in Bangladesh, collecting data over a 3-month period. The survey assessed antibiotic knowledge, usage practices, and attitudes towards misuse, employing descriptive statistics and multiple logistic regression analyses to explore associations between students' demographic characteristics and their KAP towards antibiotics. Significance was assigned at p-value < 0.05. In our study involving 501 medical students from four medical colleges in Bangladesh, we achieved a 76% response rate. Among the participants, 78.24% correctly identified antibiotics' effectiveness against bacterial infections, but 45.71% were uncertain about their efficacy against viral infections. Notably, 21.20% reported self-prescribing antibiotics, predominantly sourced from physician prescriptions (54.89%). The most common reason for antibiotic use was fever (19.02%). Senior students were less likely to have good knowledge compared to junior students, and urban students demonstrated a higher likelihood of good knowledge and positive attitude towards antibiotic resistance. This study highlights the critical need for educational reforms and antimicrobial stewardship among medical students in Bangladesh to combat antibiotic misuse and mitigate antimicrobial resistance.

Antibiotic Use at the End of Life: Current Practice and Ways to Optimize.

Infections are common complications in end of life (EOL). However, clinicians have minimal guidance regarding antibiotic decision-making in EOL care, leading to the overuse of antibiotics. While symptom relief is frequently cited as a major reason for antibiotic use in EOL, antibiotics have not been shown to provide significant improvement in symptoms outside of urinary tract infections. In addition, when prognosis is expected to be in the range of days to weeks, antibiotics have not been shown to provide significant survival benefit. Antibiotics can be beneficial in EOL care in appropriate scenarios, but the current widespread use of antibiotics in EOL requires reevaluation. There needs to be broader efforts to think about antibiotics like other invasive medical procedures in which benefits and risks are weighed, recognizing that not all patients in EOL who receive antibiotics will benefit. In addition, during care planning process, discussing and documenting antibiotic preferences will be beneficial. Non-antibiotic symptom management should be incorporated to plan of care when infection is suspected. Ultimately, the use of antibiotics at EOL should be for the clear benefit for the recipient and should be guided by the type of infection and its clinical course, patients' primary disease and its prognosis, and the preferences of patients or surrogate decision makers.

Patterns and Influencing Factors of Organisms and Sensitivity in Sputum at Sylhet

Background: Respiratory tract infections, especially pneumonia and tuberculosis, remain significant public health problems in Bangladesh. This information alone is critical to manage local pathogen distributions, antibiotic susceptibility, and response plans. Objectives: To evaluate the frequency of bacterial pathogens in sputum samples, test their antibacterial sensitivity, and relate them to various demographic factors among patients in Sylhet, Bangladesh. Methods: This cross-sectional study was carried out in the Chest Disease Clinic, Sylhet from January to June 2024.Sputum samples were taken from 120 patients diagnosed with lower respiratory tract infections. Colony and bacterial identification was done microbiologically, and antibiotic susceptibility was determined by using the Kirby-Bauer disk diffusion method. Results: The cocci were the most prevalent, with gram-positive bacteria constituting 75% of all isolates: Staphylococcus aureus 29. Co-amoxiclav had the highest sensitivity of 23 percent, while the highest resistance was recorded for linezolid at 50 percent. Tobacco use was described in 79. Overall, there was a significant association between TB-positive status and the isolation of Klebsiella pneumoniae (p = 0.032). Most participants were of lower SES, and this was observed in 59.32% of the study’s participants. Conclusions: This research found that gram-positive organisms are the most frequent cause of respiratory infections in Sylhet, with S. aureus being the most dominant isolate. The high tobacco use and the link to S. aureus colonization indicate that interventions could and should be targeted. Concerning antibiotic susceptibility patterns, the need to exercise reasonable use of antibiotics and constant monitoring of antimicrobial resistance cannot be overemphasized. These findings may help the local clinicians, help set up empirical antibacterial therapy, and facilitate the design of some targeted health interventions.

A cross-sectional analysis of antibiotic use: Attitudes and practices in the Albanian community

BackgroundAntibiotic resistance (AR) represents a global health challenge. Within the coordinated efforts to tackle AR, community education is a key strategy to enhance awareness and improve antibiotic use. The current study intends to investigate the Albanian community's attitude and practices regarding antibiotic use, including recent health related developments, like COVID-19. MethodsA cross sectional survey was conducted among Albanian residents between December 2022 and March 2023, using a standardized questionnaire which featured three sections covering demographic data, attitudes, and practices regarding antibiotic use. Statistical analysis included both descriptive statistics and the Chi-square test to assess relationships between categorical variables. ResultsThe questionnaire was effectively completed by 519 participants. The majority were females (70.1 %) within the 18–30 age range (55.5 %) and had a college/university degree (93.3 %). 53.4 % reported antibiotic use without a medical prescription, with amoxicillin and azithromycin being the most used antibiotics. Commonly cited reasons for antibiotic use were self-reported symptoms such as flu/common cold, sore throat, cough, and fever (82.3 %). 69.0 % reported following prescribed antibiotic courses, with higher adherence among females and those with higher education. Awareness of AR was considerable (78.0 %), with females evidencing more awareness compared to males. Only 34.3 % of participants reported antibiotic use for COVID-19, mostly after testing positive, with azithromycin being the most frequently used antibiotic. ConclusionsOur study highlights concerning trends in antibiotic self-medication and awareness gaps in prudent antibiotic use emphasizing the need for tailored educational programs, regulatory oversight, and robust surveillance systems in Albania's healthcare.

Antibiotic prescription pattern in pediatric intensive care unit in a tertiary care hospital: A cross-sectional study

Background: Incidence of infections in patients admitted to the Pediatric intensive care unit (PICU) is high which results in the use of antimicrobials for a prolonged duration and numbers. The rising incidence of antibiotic resistance has made it obligatory for antibiotics to be prescribed reasonably in pediatric patients. Aims and Objectives: The objective of this study was to analyze the antibiotic prescription pattern for patients admitted in pediatric intensive care unit in a tertiary care hospital. Materials and Methods: This cross-sectional study was conducted in PICU. Two hundred and seventy-five pediatric patients were incorporated in this study. The patients’ data were collected from the case sheets, recorded, and analyzed. Results: The majority (80%) of patients admitted in PICU received antibiotic(s). About 68.18% of patients were prescribed only one antibiotic. Patients in the age group of 1 m–&lt;1 year (58.18%) received more antibiotics. Pneumonia emerged to be the foremost reason for antibiotic use (45%), followed by Meningitis (14.54%). Ceftriaxone (28.27%) was the antibiotic prescribed most often. About 80.34% of antibiotics were prescribed by their generic names and 5.86% of antibiotics were prescribed as fixed-dose combinations. Conclusion: Antimicrobial resistance has become a global issue that should be tackled with extreme prudence and vigilance. This study provides insight on antibiotic prescription pattern in PICU and can prevent unnecessary use of antimicrobials.

Adverse Effect of the Duration of Antibiotic Use Prior to Immune Checkpoint Inhibitors on the Overall Survival of Patients with Recurrent Gynecologic Malignancies.

Antibiotic use preceding immune checkpoint inhibitor (ICI) treatment has been associated with a decreased efficacy of ICI in solid tumors. In this study, we evaluated the effect of antibiotic use before ICI therapy on oncological outcomes. We examined patients with recurrent gynecologic malignancies at two academic institutions. The clinical data, including antibiotic use within 60 days of ICI initiation, type of antibiotics, reasons for antibiotic use, body mass index, tumor site, chemotherapy-free interval, prior history of radiotherapy, disease control rate (DCR), and overall survival (OS), were assessed. Of 215 patients, 22.9% (n = 47) received antibiotics before ICI treatment. The most common cancer was ovarian (52.1%, n = 112), followed by cervical (24.7%, n = 53) and endometrial (16.7%, n = 36). When we divided the cohort based on antibiotic use before ICIs, there were no significant differences in the DCR and baseline characteristics between the two groups. On multivariate analyses, the variables associated with poor OS were previous use of antibiotics for a cumulative duration of >14 days (HR 2.286, 95% CI 1.210-4.318; p = 0.011); Eastern Cooperative Oncology Group 2 or 3 (HR 4.677, 95% CI 2.497-8.762; p < 0.001); and chemotherapy-free interval of <6 months (HR 2.007, 95% CI 1.055-3.819; p = 0.034). Prior use of antibiotics for a cumulative duration of >14 days was associated with reduced survival in recurrent gynecologic malignancies.

Streptococcus salivarius Probiotics to Prevent Acute Otitis Media in Children

New approaches for the prevention of acute otitis media (AOM), the most common reason for antibiotic use in children, are needed. To assess the efficacy of the Streptococcus salivarius K12 oral probiotics in the primary prevention of AOM. This double-blind, randomized placebo-controlled clinical trial was conducted from August 1, 2020, to May 31, 2021, at 50 day care centers in the Oulu region of Finland. A total of 827 children aged 1 to 6 years attending day care were included. The exclusion criteria consisted of ongoing antimicrobial prophylaxis or immunodeficiency. The follow-up time was 6 months and was completed on May 31, 2021. Data were analyzed from October 24, 2022, to September 16, 2023, based on intention to treat. Eligible participants were randomly allocated to receive 1 daily dose of a S salivarius K12 product or placebo every evening for 6 months. A daily dose was defined as 1 sachet of soluble oral powder for children younger than 3 years or 1 chewable tablet for children 3 years or older containing 1 × 109 colony-forming units of S salivarius K12. The primary outcome was the proportion of children with at least 1 episode of AOM requiring antimicrobial therapy within 6 months of randomization. All physician visits and purchases of antimicrobial drugs were retrieved from the electronic national medical record and prescription register. The primary outcome was met if the legal guardian had purchased an antimicrobial prescription for AOM. A total of 827 children with a mean (SD) age of 4.1 (1.6) years (433 boys [52.4%]) were randomized to S salivarius K12 oral products (n = 413) or placebo (n = 414). Thirty-four children (8.2%) in the S salivarius group and 24 children (5.8%) in the placebo group experienced at least 1 episode of AOM requiring antimicrobial therapy during the 6-month follow-up period (relative risk, 1.42 [95% CI, 0.86-2.34]; proportion difference, -2.44% [95% CI, -5.94% to 1.09%]; P = .17). Time to first AOM episode did not differ between the groups (174 [95% CI, 171-177] days in the S salivarius group vs 176 [95% CI, 173-179] days in the placebo group; P = .18). In this randomized placebo-controlled clinical trial, the daily use of the S salivarius K12 products for 6 months did not reduce the occurrence of AOM. New approaches for primary prevention of AOM among children are needed. ClinicalTrialsRegister.eu Identifier: 2020-001076-14.

Antibiotic point prevalence survey and antimicrobial resistance in hospitalized patients across Peruvian reference hospitals

BackgroundPeru reports higher levels than other countries in Latin America of resistance to antimicrobials among Gram-positive and Gram-negative bacteria, however data on antibiotic use in Peru are scarce. This study aims to estimate the prevalence and quality of antibiotic prescription in hospitalized patients and to determine the antibiotic susceptibility rates of bacteria causing key bacterial infections. MethodsWe carried out a point prevalence survey of antibiotic prescription at ten public hospitals in nine regions of Peru. Data was collected from patients hospitalized during a 3-week period, with details about antibiotic use, patient information, and antimicrobial susceptibility. Results1620 patient charts were reviewed; in 924 cases antibiotics were prescribed (57.0 %, range 45.9–78.9 %). Most of the antibiotics (74.2 %) were prescribed as empirical treatment, only 4.4 % as targeted treatment. For 9.5 % of cases the reason for antibiotic use was unknown. Cephalosporins were the most prescribed (30.0 %), followed by carbapenems (11.3 %). Ninety-four blood cultures were positive for bacterial growth, 48.8 % of the Staphylococcus aureus were methicillin-resistant, among Escherichia coli and Klebsiella pneumoniae, 51.7 % and 72.7 % were resistant to third-generation cephalosporins (3GC), 3.4 % and 18.2 % were resistant to carbapenems, respectively. Among bacteria isolated from urine cultures (n = 639), 43.9 % of E. coli and 49.2 % of K. pneumoniae were resistant to 3GC, and 0.9 % of E. coli and 3.2 % of K. pneumoniae were resistant to meropenem. ConclusionsThe overall proportion of hospitalized patients receiving antibiotics in hospitals from different regions in Peru was high, with only a small proportion receiving targeted treatment. Cephalosporins and carbapenems were the most frequently prescribed antibiotics, reflecting high resistance rates against 3GC and carbapenems in Enterobacterales isolated from blood and urine.

Sources of antibiotics for acute respiratory infection in children aged &lt;5 years children in South Asia: A multicountry study

Background: In South Asia, a region of almost 2 billion people across 8 countries, acute respiratory infections (ARIs) are associated with significant morbidity and mortality in children aged &lt;5 years. Although ~80% of ARIs are due to viral etiology and are often self-limiting, they remain the single largest reason for antibiotic use in children aged &lt;5 years in South Asia. We investigated the sources and dispensing pattern of antibiotics for ARIs in children aged &lt;5 years in South Asia. Methods: We analyzed nationally representative, population-based, publicly available household survey data from 6 South Asian countries’ Demographic and Health Surveys (DHS): Afghanistan, Bangladesh, India, Maldives, Nepal, and Pakistan. The outcome of interest was the source of antibiotics for children aged &lt;5 years who reportedly had symptoms compatible with ARI (cough, fever, and runny nose) and had received antibiotics for the ARI episode in the 2 weeks preceding the survey. We used a generalized estimating equation with an exchangeable correlation structure to account for country-specific cluster-level correlation to estimate the odds of sources of antibiotics usage. Models were adjusted for age, sex, type of place of residence, wealth index, and parents’ education. To analyze the data, we used the sample weight supplied by the DHS to ensure that our results appropriately reflect the target population in each of the countries studied. Results: In total, across the 6 South Asian countries, 24,104 children aged &lt;5 years had symptoms of ARI, 7,587 (31%; 95% CI, 30–33) from received antibiotics. A higher proportion of antibiotic usage for ARIs episodes occurred in Afghanistan (66%), followed by Maldives (53%), Pakistan (45%), and Nepal (43%). Regarding the source of antibiotics, a higher proportion of antibiotics was obtained from the private medical sector in India, followed by unqualified sources in Bangladesh, and the public sector in Afghanistan. Our adjusted multivariable analysis revealed that, in comparison to the public sector, participants were 2.6 times (aOR, 2.6; 95% CI, 1.6–4.3) more likely to receive antibiotics from private medical sector drug sources in Nepal and 1.3 times more likely (aOR, 1.3; 95% CI, 1.1–1.5) in Afghanistan. Conclusions: In South Asian countries, the private medical sector was the most common primary source of antibiotics for children with ARIs. Targeted efforts to create awareness around antibiotic dispensing and guidelines to improve practices may curtail the use of antibiotics for ARIs in children aged &lt;5 years in South Asia.Disclosures: None

Prescribing Antibiotics in Public Primary Care Clinics in Singapore: A Retrospective Cohort Study.

Antibiotic prescription practices in primary care in Singapore have received little scholarly attention. In this study, we ascertained prescription prevalence and identified care gaps and predisposing factors. A retrospective study was conducted on adults (>21 years old) at six public primary care clinics in Singapore. Prescriptions >14 days were excluded. Descriptive statistics were used to showcase the prevalence data. We used chi-square and logistic regression analyses to identify the factors affecting care gaps. A total of 141,944 (4.33%) oral and 108,357 (3.31%) topical antibiotics were prescribed for 3,278,562 visits from 2018 to 2021. There was a significant reduction in prescriptions (p < 0.01) before and after the pandemic, which was attributed to the 84% reduction in prescriptions for respiratory conditions. In 2020 to 2021, oral antibiotics were most prescribed for skin (37.7%), genitourinary (20.2%), and respiratory conditions (10.8%). Antibiotic use in the "Access" group (WHO AWaRe classification) improved from 85.6% (2018) to 92.1% (2021). Areas of improvement included a lack of documentation of reasons for antibiotic use, as well as inappropriate antibiotic prescription for skin conditions. There was a marked reduction in antibiotic prescriptions associated with the onset of the COVID-19 pandemic. Further studies could address the gaps identified here and evaluate private-sector primary care to inform antibiotic guidelines and the local development of stewardship programs.

Prevalence and Antibiogram Pattern of Klebsiella pneumoniae in a Tertiary Care Hospital in Makkah, Saudi Arabia: An 11-Year Experience.

Infectious disease is one of the greatest causes of morbidity and mortality worldwide, and with the emergence of antimicrobial resistance, the situation is worsening. In order to prevent this crisis, antimicrobial resistance needs to be monitored carefully to control the spread of multidrug-resistant bacteria. Therefore, in this study, we aimed to determine the prevalence of infection caused by Klebsiella pneumoniae and investigate the antimicrobial profile pattern of K. pneumoniae in the last eleven years. This retrospective study was conducted in a tertiary hospital in Makkah, Saudi Arabia. Data were collected from January 2011 to December 2021. From 2011 to 2021, a total of 61,027 bacterial isolates were collected from clinical samples, among which 14.7% (n = 9014) were K. pneumoniae. The antibiotic susceptibility pattern of K. pneumoniae revealed a significant increase in the resistance rate in most tested antibiotics during the study period. A marked jump in the resistance rate was seen in amoxicillin/clavulanate and piperacillin/tazobactam, from 33.6% and 13.6% in 2011 to 71.4% and 84.9% in 2021, respectively. Ceftazidime, cefotaxime, and cefepime resistance rates increased from 29.9%, 26.2%, and 53.9%, respectively, in 2011 to become 84.9%, 85.1%, and 85.8% in 2021. Moreover, a significant increase in the resistance rate was seen in both imipenem and amikacin, with an average resistance rate rise from 6.6% for imipenem and 11.9% for amikacin in 2011 to 59.9% and 62.2% in 2021, respectively. The present study showed that the prevalence and drug resistance of K. pneumoniae increased over the study period. Thus, preventing hospital-acquired infection and the reasonable use of antibiotics must be implemented to control and reduce antimicrobial resistance.

Opinions of Prospective Dentists and Prospective Teachers on Antibiotic Use.

The purpose of this study was to examine the opinions of prospective dentists and prospective teachers on antibiotic use. In this study, a survey method based on a quantitative research paradigm was utilized. A 19-item instrument was applied to the sample group including 414 university students attending to the Faculty of Dentistry and Faculty of Education. The instrument was composed of three main subscales in addition to demographic characteristics. The first part focused on attitudes, the second part focused on subjective norms, and the third part focused on the prospective dentists and prospective teachers' intentions regarding the phenomenon of antibiotics use. While the dependent variables of the study were the participants' levels of agreement in the subscales of the instrument, the independent variable was faculty studied. The data were analyzed through descriptive statistics, and the Mann-Whitney U test was used to compare the participants' views on antibiotic use. The findings in terms of the faculties showed that dentistry and education faculties in our country prepare well in expanding their reasonable consumption of antibiotics. Yet, antibiotics are used more incorrectly by some prospective teachers than by prospective dentists. According to the findings in terms of subscales, the participants have positive attitudes toward the reasonable use of antibiotics in terms of the attitude subscale. However, the results from the subjective norm indicated that participants are influenced by their environment in their antibiotic use. Finally, the results from the intention indicated that participants avoid using antibiotics irregularly or frequently.

Antibiotic Use and Stewardship Indicators in the First- and Second-Level Hospitals in Zambia: Findings and Implications for the Future.

Introduction: There are increasing concerns with growing rates of antimicrobial resistance (AMR) across Africa, including in Zambia, enhanced by inappropriate utilization of antibiotics across the sectors. There is a need in hospitals to document current prescribing patterns via point prevalence surveys (PPS) alongside recognized indicators to improve future use. The findings can subsequently be used to develop and instigate appropriate antimicrobial stewardship programs (ASPs) to improve the quality of future antimicrobial prescribing across Zambia. This includes encouraging the prescribing of 'Access' over 'Watch' and 'Reserve' antibiotics where pertinent. Methods: A PPS was undertaken using the WHO methodology among 10 first- and second-level public hospitals across the 10 provinces of Zambia. A sampling process was used to select the hospitals. Results: The prevalence of antibiotic use among the in-patients was 307/520 (59.0%), with a high rate of empiric prescribing of ceftriaxone at 36.1% of all antibiotics prescribed (193/534). The reason for antibiotic use was recorded in only 15.7% of occasions and directed treatment prescribed in only 3.0% of occasions. Compliance with the national standard treatment guidelines (STGs) was also low at only 27.0% of occasions. Conclusion: High empiric prescribing, limited documentation of the rationale behind antibiotic prescribing, high use of 'Watch' antibiotics, and limited compliance to STGs among surveyed hospitals requires the urgent instigation of ASPs across Zambia to improve future prescribing.

Social influence is the main driver of emergency physicians' intention to use an antibiotic clinical decision support mobile application

Upper respiratory tract infection (URTI) is one of the most common reasons for antibiotic use, although they are generally not required for this indication [1]. URTI accounts for a substantial number of emergency department (ED) attendances, with over one-third of cases being prescribed antibiotics [2]. In a mixed-methods study involving eight EDs in the USA, it was observed that the fast-paced environment of the ED encouraged unnecessary use of antibiotics [3].

Improving Adherence to AAP Acute Otitis Media Guidelines in an Academic Pediatrics Practice through a Quality Improvement Project.

Introduction:Acute otitis media (AOM) is the most common reason for antibiotic use in children. The American Academy of Pediatrics (AAP) published its latest AOM guidelines in 2013. A safety-net antibiotic prescription (SNAP) is recommended for some patients based on age, severity, and duration of symptoms. At baseline, 78% of patients diagnosed with AOM in our general pediatrics practice met AAP guidelines, and 20% of eligible patients received a SNAP according to guidelines. We aimed to increase adherence to AAP AOM guidelines in an academic general pediatrics clinic from 78% to 90% by January 2020.Methods:A quality improvement team determined key drivers and developed interventions. Patients included were 6 months to 12 years old with AOM. Encounters were reviewed for adherence to AAP AOM guidelines. During the project, interventions included an ear pain note template, which generated guideline-based recommendations, note template education in clinic orientation sessions, a didactic session on AOM management, and reminders on workstations. Data were analyzed using P-charts.Results:Percent of AOM encounters (n = 1266) adhering to AAP AOM guidelines increased from 78% to 92%. We also reviewed two process measures. First, the use of the ear pain note template increased from 0% to 44%. Second, the percent of AOM encounters where an eligible patient received a SNAP increased from 21% to 78% (encounters n = 421).Conclusion:We demonstrate increased adherence to AAP AOM guidelines, including improved use of SNAPs after introducing a note template with clinical decision support and provider educational sessions.

143. Antibiotic Use for Common Infections in British Columbia and Ontario: A Review of Outpatient Prescribing to Seniors from 2000 – 2018

Abstract Background Antimicrobials remain among the most prescribed medications in Canada, with over 90% prescribed in outpatient settings. Older adults (aged ≥65 years) prescribed antimicrobials are particularly vulnerable to adverse drug events and antimicrobial resistance. This study compared annual rates of indication-associated, outpatient prescribing to seniors across two Canadian provinces. Methods All outpatient, oral antimicrobials dispensed to older adults (≥65 years) were identified from administrative health databases, from 2000 to 2018. Antimicrobials were limited to outpatient use only and linked to an indication using a 3-tiered diagnostic hierarchy. When possible, a record of dispensation was matched to a tier 1 indication (always require antibiotics) first. In the absence of a tier 1 indication, priority was given to tier 2 (sometimes require antibiotics), then 3 (never require antibiotics). Prescription rates were calculated per 1000 population, and trends were examined overall, by drug class, and patient demographics. Results Our study included over 18 million individuals (aged ≥65 years) with a total of 23,773,552 antibiotic prescriptions issued to seniors, for common infections. In both provinces, prescribing for tier 1 diagnoses increased over the study period (BC: 44%; ON: 28%). Urinary tract infections accounted for most prescriptions within this tier (ON: 89 prescriptions/1000, BC: 129 prescriptions/1000 population by 2018). Pneumonia-associated prescribing increased by roughly 10% in both provinces. In any given study year, for both provinces, tier 3 diagnosis was the most common reason for antibiotic use, accounting for 50% of all indication-associated antibiotic prescribing. As diagnoses within this tier do not warrant prescribing all antibiotics issued are therefore inappropriate prescriptions. Figure 1. Rates of indication-associated antibiotic use in Canadian seniors, from 2000 to 2018. Conclusion Elevated prescribing to seniors continues across Canadian outpatient settings. Antibiotic prescribing remains an issue of high concern with 50% of all antimicrobials prescribed to seniors, for common infections, used inappropriately.

Appropriateness of Outpatient Antibiotic Use in Seniors across Two Canadian Provinces.

Antimicrobials are among the most prescribed medications in Canada, with over 90% of antibiotics prescribed in outpatient settings. Seniors prescribed antimicrobials are particularly vulnerable to adverse drug events and antimicrobial resistance. The extent of inappropriate antibiotic prescribing in outpatient Canadian medical practice, and the potential long-term trends in this practice, are unknown. This study is the first in Canada to examine prescribing quality across two large-scale provincial healthcare systems to compare both quantity and quality of outpatient antibiotic use in seniors. Population-based analyses using administrative health databases were conducted in British Columbia (BC) and Ontario (ON), and all outpatient, oral antimicrobials dispensed to seniors (≥65 years) from 1 January 2000 to 31 December 2018 were identified. Antimicrobials were linked to an indication using a 3-tiered hierarchy. Tier 1 indications, which always require antibiotics, were given priority, followed by Tier 2 indications that sometimes require antibiotics, then Tier 3, which never require antibiotics. Prescription rates were calculated per 1000 population, and trends were examined overall, by drug class, and by patient demographics. Prescribing remained steady in both provinces, with 11,166,401 prescriptions dispensed overall in BC, and 27,656,014 overall in ON. BC prescribed at slightly elevated rates (range: 790 to 930 per 1000 residents), in comparison to ON (range: 745 to 785 per 1000 residents), throughout the study period. For both provinces, a Tier 3 diagnosis was the most common reason for antibiotic use, accounting for 50% of all indication-associated antibiotic prescribing. Although Tier 3 indications remained the most prescribed-for diagnoses throughout the study period, a declining trend over time is encouraging, with much room for improvement remaining. Elevated prescribing to seniors continues across Canadian outpatient settings, and prescribing quality is of high concern, with 50% of all antimicrobials prescribed inappropriately for common infections that do not require antimicrobials.

Predictive Indicators for Necrotizing Enterocolitis With the Presence of Portal Venous Gas and Outcomes of Surgical Interventions.

Objectives: Portal venous gas (PVG) was an important clinical sign in stage II or III necrotizing enterocolitis (NEC) in preterm neonates. Not a proper predictive indicator was found to predict the diseases (NEC with the presence of PVG) up to now. There is a need to put forward predictive indicators and compare the predictive effects among them.Methods: We conducted a retrospective study of preterm neonates with NEC-PVG (n = 61) or NEC-non PVG (n = 62) from 2014 to 2021. Predictive indicators were put forward and determined by receiver operating characteristic curve analysis. An analysis of the surgical interventions and their outcomes was performed.Results: The incidence rate of NEC among preterm neonates was 4.99%; surgical and conservative interventions accounted for 20.47 and 75.07%, and the mortality rate was 0.03%. The composition ratio of shock in the NEC-PVG group increased 13.2% (P = 0.029). C-reactive protein, fibrinogen degradation product, and blood glucose had better predictive effects in the predictive indicators (P < 0.05). Intestinal necrosis and subependymal hemorrhage in the outcomes of surgical interventions had a strong relationship with the presence of PVG in NEC II/III (P < 0.05).Conclusion: Early and reasonable use of antibiotics, improvement of coagulation function, rectification of acidosis, and decreased blood glucose could cut down the occurrence of the disease (NEC with the presence of PVG).
