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.

Tier 3

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.

Abstract Objectives To assess recent community antibiotic prescribing for French children and identify areas of potential improvement. Methods We analysed 221 768 paediatric (<15 years) visits in a national sample of 680 French GPs and 70 community paediatricians (IQVIA’s EPPM database), from March 2015 to February 2017, excluding well-child visits. We calculated antibiotic prescription rates per 100 visits, separately for GPs and paediatricians. For respiratory tract infections (RTIs), we described broad-spectrum antibiotic use and duration of treatment. We used Poisson regression to identify factors associated with antibiotic prescribing. Results GPs prescribed more antibiotics than paediatricians [prescription rate 26.1 (95% CI 25.9–26.3) versus 21.6 (95% CI 21.0–22.2) per 100 visits, respectively; P < 0.0001]. RTIs accounted for more than 80% of antibiotic prescriptions, with presumed viral RTIs being responsible for 40.8% and 23.6% of all antibiotic prescriptions by GPs and paediatricians, respectively. For RTIs, antibiotic prescription rates per 100 visits were: otitis, 68.1 and 79.8; pharyngitis, 67.3 and 53.3; sinusitis, 67.9 and 77.3; pneumonia, 80.0 and 99.2; bronchitis, 65.2 and 47.3; common cold, 21.7 and 11.6; bronchiolitis 31.6 and 20.1; and other presumed viral RTIs, 24.1 and 11.0, for GPs and paediatricians, respectively. For RTIs, GPs prescribed more broad-spectrum antibiotics [49.8% (95% CI 49.3–50.3) versus 35.6% (95% CI 34.1–37.1), P < 0.0001] and antibiotic courses of similar duration (P = 0.21). After adjustment for diagnosis, antibiotic prescription rates were not associated with season and patient age, but were significantly higher among GPs aged ≥50 years. Conclusions Future antibiotic stewardship campaigns should target presumed viral RTIs, broad-spectrum antibiotic use and GPs aged ≥50 years.

Abstract Background About 80% of antibiotic prescriptions are written in outpatient settings. Outpatient antibiotic use (AU) is highest in the Southern United States. Tennessee consistently has one of the highest AU rates in the country. Previous analyses found that 1,195 prescriptions were filled in Tennessee per 1,000 total population in 2016. Moreover, 50% of all outpatient antibiotic prescriptions were written by 9.3% of prescribers. We sought to assess Tennessee outpatient antibiotic prescribing trends, comparing 2016 with 2018 data. Methods The Tennessee IQVIA outpatient antibiotic prescription dataset from January 1 to December 31, 2018 was analyzed and compared to 2016 results. Orally administered antibacterial agents were included. Patients < 20 years old were classified as pediatric. County level population data were obtained from the Tennessee Department of Health. Antibiotic prescription rates were calculated as antibiotics prescribed per 1,000 population in the specified age group. Analysis was performed using SAS 9.4. Results The statewide AU rate decreased from 1,195 in 2016 to 1,074 in 2018 per 1,000 population. Consistent with the previous analysis, female patients (1,288), those over 65 years (1,459), and those < 2 years (1,372) had the highest rates of AU in 2018. Lower rates were observed in all age groups in 2018 except for the 3–9 years group. While narrow penicillins and macrolides remain the most frequently prescribed antibiotics, amoxicillin-clavulanate and ciprofloxacin fell out of the top five antibiotics used in adults, and amoxicillin-clavulanate fell out of the top five antibiotics used in pediatrics. Similar to 2016, 9.2% (3,098) of the providers contributed to 50% of the total prescriptions in 2016, and 2,090 of the 2,994 (69.8%) 2016 highest prescribing providers were also among the highest prescribers in 2018. Conclusion Despite a decline in outpatient antibiotic prescription volume, Tennessee remains one of the nation’s highest prescribing states. While a decline in broad spectrum antibiotic prescriptions may indicate a shift to more appropriate usage, these data do not include indication, excluding appropriate use assessment. Identifying and focusing antibiotic stewardship interventions for consistently high prescribers remains a priority for Tennessee. Disclosures All Authors: No reported disclosures

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.

Background: Antibiotic overuse contributes to antibiotic resistance and unnecessary adverse drug effects. Antibiotic stewardship interventions have primarily focused on acute-care settings. Most antibiotic use, however, occurs in outpatients with acute respiratory tract infections such as pharyngitis. The electronic health record (EHR) might provide an effective and efficient tool for outpatient antibiotic stewardship. We aimed to develop and validate an electronic algorithm to identify inappropriate antibiotic use for pediatric outpatients with pharyngitis. Methods: This study was conducted within the Children’s Hospital of Philadelphia (CHOP) Care Network, including 31 pediatric primary care practices and 3 urgent care centers with a shared EHR serving >250,000 children. We used International Classification of Diseases, Tenth Revision (ICD-10) codes to identify encounters for pharyngitis at any CHOP practice from March 15, 2017, to March 14, 2018, excluding those with concurrent infections (eg, otitis media, sinusitis), immunocompromising conditions, or other comorbidities that might influence the need for antibiotics. We randomly selected 450 features for detailed chart abstraction assessing patient demographics as well as practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for evaluating the electronic algorithm. Criteria for appropriate use included streptococcal testing, use of penicillin or amoxicillin (absent β-lactam allergy), and a 10-day duration of therapy. Results: In 450 patients, the median age was 8.4 years (IQR, 5.5–9.0) and 54% were women. On chart review, 149 patients (33%) received an antibiotic, of whom 126 had a positive rapid strep result. Thus, based on chart review, 23 subjects (5%) diagnosed with pharyngitis received antibiotics inappropriately. Amoxicillin or penicillin was prescribed for 100 of the 126 children (79%) with a positive rapid strep test. Of the 126 children with a positive test, 114 (90%) received the correct antibiotic: amoxicillin, penicillin, or an appropriate alternative antibiotic due to b-lactam allergy. Duration of treatment was correct for all 126 children. Using the electronic algorithm, the proportion of inappropriate prescribing was 28 of 450 (6%). The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were sensitivity (99%, 422 of 427); specificity (100%, 23 of 23); positive predictive value (82%, 23 of 28); and negative predictive value (100%, 422 of 422). Conclusions: For children with pharyngitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. Future work should validate this approach in other settings and develop and evaluate the impact of an audit and feedback intervention based on this tool.Funding: NoneDisclosures: None

Abstract Background In 2011, The Infectious Diseases Society of America released a clinical practice guideline (CPG) that recommended short-course antibiotic therapy and avoidance of fluoroquinolones for uncomplicated urinary tract infections (UTIs). Recommendations from this CPG were rapidly disseminated to clinicians via review articles, UpToDate, and the Centers for Disease Control and Prevention website; however, it is unclear if this CPG had an impact on national antibiotic prescribing practices. Methods We performed a retrospective cohort study of outpatient and emergency department visits within a commercial insurance database between January 1, 2009, and December 31, 2013. We included nonpregnant women aged 18–44 years who had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for a UTI with a concurrent antibiotic prescription. We performed interrupted time series analyses to determine the impact of the CPG on the appropriateness of the antibiotic agent and duration. Results We identified 654 432 women diagnosed with UTI. The patient population was young (mean age, 31 years) and had few comorbidities. Fluoroquinolones, nonfirstline agents, were the most commonly prescribed antibiotic class both before and after release of the guidelines (45% vs 42%). Wide variation was observed in the duration of treatment, with >75% of prescriptions written for nonrecommended treatment durations. The CPG had minimal impact on antibiotic prescribing behavior by providers. Conclusions Inappropriate antibiotic prescribing is common for the treatment of UTIs. The CPG was not associated with a clinically meaningful change in national antibiotic prescribing practices for UTIs. Further interventions are necessary to improve outpatient antibiotic prescribing for UTIs.

Background: Patient education on treatment choices for common respiratory tract infections (RTIs) is important to encourage appropriate antibiotic use. Evidence shows that use of leaflets about RTIs can help reduce antibiotic prescribing. TARGET leaflets facilitate patient–clinician communication in consultations. Aim: To explore patient, healthcare professional (HCP) and general practice (GP) staff views on the current Treating Your Infection (TYI)-RTI leaflet and proposed new ‘antibiotic effect’ column aimed at sharing information on the limited effect antibiotics have on the duration of RTIs. Methods: Service evaluation underpinned by Com-B behavioural framework, using patient and HCP questionnaires, and GP staff interviews/focus groups. Results: Patients completed 83 questionnaires in GP waiting rooms. A lack of patient understanding about usual illness duration influenced their use of antibiotics for some RTIs. Patients provided positive feedback about the leaflet, reporting it increased their capability to self-care, re-consult when necessary and increase understanding of illness duration. Patients indicated they would value information on the difference antibiotics can make to illness duration. In total, 43 HCP questionnaires were completed and 16 GP staff participated in interviews/focus groups. Emerging themes included: barriers and facilitators to leaflet use; modifications; and future dissemination of the leaflet. GP staff stated that the ‘antibiotic effect’ column should not be included in the leaflet. Conclusion: Patient education around usual illness duration, side effects of antibiotics and back-up prescriptions gives patients a greater control of their infection management. As GP staff opposed the extra information about benefits of antibiotics on illness duration, this will not be added.

Abstract Background Self-medication with antibiotics (SMA) is one of the most dangerous inappropriate antibiotic use behaviors. This study aims to investigate the impact of parental SMA for children before a consultation on their doctor’s subsequent antibiotic prescribing behavior, including intravenous (IV) antibiotic use in the clinical setting of China. Methods A cross-sectional survey was conducted between June 2017 and April 2018 in three provinces of China. A total of 9526 parents with children aged 0–13 years were investigated. Data from 1275 parents who had self-medicated their children and then visited a doctor in the past month were extracted and analyzed. Results One-third (410) of the studied children had parental SMA before the consultation and 83.9% of them were subsequently prescribed antibiotics by doctors. Children with parental SMA were more likely to be prescribed antibiotics (aOR = 7.79, 95% CI [5.74–10.58]), including IV antibiotics (aOR = 3.05, 95% CI [2.27–4.11]), and both oral and IV antibiotics (aOR = 3.42, 95% CI [2.42–4.84]), than children without parental SMA. Parents with SMA behaviors were more likely to request antibiotics (aOR = 4.05, 95% CI [2.59–6.31]) including IV antibiotics (aOR = 2.58, 95% CI [1.40–4.76]), and be fulfilled by doctors (aOR = 3.22, 95% CI [1.20–8.63]). Conclusions Tailored health education for parents is required in both community and clinical settings to discourage parental SMA for children. The doctors should not prescribe unnecessary antibiotics to reinforce parents’ SMA behaviors. We recommend expanding the current IV antibiotics ban in outpatient settings of China to cover outpatient pediatrics.

Background:Knowledge, attitudes, and practices regarding antibiotic prescribing for upper respiratory tract infections (URIs) have not been well described among obstetrician-gynecologists (OB/GYNs). This information is useful for determining whether an OB/GYN-specific program promoting appropriate antibiotic use would significantly contribute to the efforts to decrease inappropriate antibiotic use among primary care providers.Methods:An anonymous questionnaire asking about the treatment of URIs was sent to 1031 obstetrician-gynecologists.Results:The overall response rate was 46%. The majority of respondents (92%) were aware of the relationship between antibiotic use and antibiotic resistance, and respondents estimated that 5% of their patients had URI symptoms at their office visits. Overall, 56% of respondents reported that they would prescribe an antibiotic for uncomplicated bronchitis and 43% for the common cold. OB/GYNs with the fewest years of experience were less likely than those with the most years of experience to report prescribing for uncomplicated bronchitis (Odds ratio (OR) 0.46, 95% confidence interval (CI) 0.23 to 0.91) or the common cold (OR 0.44, CI 0.22 to 0.89). The majority of respondents (60%) believed that most patients wanted an antibiotic for URI symptoms, with male OB/GYNs being more likely than female OB/GYNs (OR 2.1, CI 1.2 to 3.8) to hold this belief. Both male OB/GYNs (OR 1.9, CI 1.1 to 3.4) and rural practitioners (OR 2.1, CI 1.1 to 4.0) were more likely to believe that it was hard to withhold antibiotics for URI symptoms because other physicians prescribe antibiotics for these symptoms. OB/GYNs who believed that postgraduate training prepared them well for primary care management were more likely than those who did not (OR 2.1, CI 1.1 to 4.2) to believe that they could reduce antibiotic prescribing without reducing patient satisfaction.Conclusion:Multiple demographic factors affect attitudes and reported practices regarding antibiotic prescribing. However, in view of the low proportion of office visits for URIs, an OB/GYN-specific program is not warranted.
