Abstract Background Antibiotic stewardship initiatives can leverage metrics that make peer-peer comparisons. A commonly used metric measures how frequently a clinician prescribes antibiotics for acute respiratory infections (ARIs), as defined by diagnostic codes. However, it is unclear if clinicians differ in their use of ARI diagnostic codes. In this study, we evaluated differences in how frequently clinicians code for ARIs and factors that are associated with the use of ARI diagnostic codes in Emergency Department (ED) and Urgent Care (UC) visits across an integrated healthcare system. Methods We analyzed a retrospective cohort of all ED and UC patient-visits across 129 Veterans Affairs medical centers during 2016-2018. ARI visits were identified using ICD-10 codes for acute bronchitis, influenza, pharyngitis, sinusitis, and upper respiratory tract infections for clinicians with 100 or more visits. A generalized linear mixed model with a link logit function that accounted for clustering at the clinician and facility-level was used to calculate median odds ratios (OR) and to identify factors associated with increased likelihood of entering an ARI code. Results There were 6,016,499 patient-visits, and 519,389 (8.6%) were coded as an ARI (Table 1). The mean rate of ARI diagnoses across all visits was 8.9% (SD 2.5%) at the facility-level and 7.4% (SD 4.5%) at the clinician-level (Table 2). The median OR was 2.19 (95% CI 2.18, 2.22), suggesting there was between-clinician variation in coding for ARI diagnoses. Visits were significantly more likely to be coded as ARIs if seen by an advanced practice provider (OR=2.36, 95% CI 2.19, 2.54), if a fever was recorded (OR=4.20, 95% CI 4.18, 4.29), and if the visit occurred between December-March (OR=1.97, 95% CI 1.96, 1.98). Approximately 2/5th of the variability (41.4%) in assigning an ARI diagnostic code was explained by differences across individual clinicians. Conclusion There was substantial variability in how frequently ED and UC clinicians coded a visit as an ARI, and a large proportion of the variability was explained by differences across clinicians. Unmeasured factors could include different approaches to using diagnostic codes. ARI metrics based on diagnostic codes may need to account for differences in clinicians’ coding behavior.

Many hospitals have established inpatient antibiotic stewardship programs (ASPs), but outpatient activities remain limited. In 2016, the United Hospital Fund (UHF), an independent nonprofit working to build a more effective healthcare system for every New Yorker, launched a 2-stage grant-funded initiative to evaluate outpatient antibiotic stewardship, focusing on adults with acute respiratory infections (ARIs). Conclusions from stage 1 included few outpatient antibiotic stewardship activities, variation in prescribing, macrolides as the most commonly prescribed antibiotic, and provider interest in improving prescribing.1

Abstract Background Antibiotic overuse remains a significant problem in inpatient and outpatient settings. The objective of this study was to develop a methodology to evaluate antibiotic use across inpatient and ambulatory care sites in an integrated healthcare system in order to prioritize antibiotic stewardship efforts. Methods We conducted an epidemiologic study of antibiotic use across an integrated healthcare system on 12 randomly-selected days between October 1, 2017 and September 30, 2018. Inpatients and perioperative patients were recorded as having received an antibiotic if they were administered ≥1 dose of a systemic antibacterial agent. Outpatients were recorded as having received an antibiotic if they were prescribed ≥1 systemic antibacterial agent. Results On the study days, 10.9% (95% CI 10.6–11.3%) of patients received an antibiotic. Of all antibiotics administered or prescribed, 54.1% were from ambulatory care (95% CI 52.6–55.7%), 38.0% were from the hospital, (95% CI 36.6–39.5%), and 7.8% (95% CI 7.1–7.8%) were perioperative. The emergency department/urgent care centers, adult outpatient clinics, and adult noncritical care inpatient wards accounted for 26.4% (95% CI: 25.0–27.7%), 23.8% (95% CI: 22.6–25.2), and 23.9% (95% CI 22.7–25.3) of antibiotic use, respectively. Only 9.2% (95% CI: 8.3–10.1%) of all antibiotics were administered in critical care units. Antibiotics with a broad spectrum of Gram-negative activity accounted for 30.4% (95% CI: 29.0–31.9%) of all antibiotics prescribed. Infections of the respiratory tract were the leading indication for antibiotic use. Conclusion In an integrated healthcare system, nearly three-quarters of antibiotic use occurred in the emergency department/urgent care centers, adult outpatient clinics, and adult noncritical care inpatient wards. Antibiotics with a broad spectrum of Gram-negative activity accounted for a large portion of antibiotic use. Analysis of antibiotic utilization across the spectrum of inpatient and ambulatory care is useful to prioritize antibiotic stewardship efforts. Disclosures All authors: No reported disclosures.

The objective of this study was to develop a methodology to evaluate antibiotic use across inpatient and ambulatory care sites in an integrated healthcare system to prioritize antibiotic stewardship efforts. Methods We conducted an epidemiologic study of antibiotic use across an integrated healthcare system on 12 randomly selected days from 2017 to 2018. For inpatients and perioperative patients, administrations of antibiotics were recorded, whereas prescriptions were recorded for outpatients. Results On the study days, 10.9% (95% confidence interval [CI], 10.6%–11.3%) of patients received antibiotics. Of all antibiotics, 54.1% were from ambulatory care (95% CI, 52.6%–55.7%), 38.0% were from the hospital (95% CI, 36.6%–39.5%), and 7.8% (95% CI, 7.1%–8.7%) were perioperative. The emergency department/urgent care centers, adult outpatient clinics, and adult non–critical care inpatient wards accounted for 26.4% (95% CI, 25.0%–27.7%), 23.8% (95% CI, 22.6%–25.2%), and 23.9% (95% CI, 22.7%–25.3%) of antibiotic use, respectively. Only 9.2% (95% CI, 8.3%–10.1%) of all antibiotics were administered in critical care units. Antibiotics with a broad spectrum of gram-negative activity accounted for 30.4% (95% CI, 29.0%–31.9%) of antibiotics. Infections of the respiratory tract were the leading indication for antibiotics. Conclusions In an integrated healthcare system, more than half of antibiotic use occurred in the emergency department/urgent care centers and outpatient clinics. Antibiotics with a broad spectrum of gram-negative activity accounted for a large portion of antibiotic use. Analysis of antibiotic utilization across the spectrum of inpatient and ambulatory care is useful to prioritize antibiotic stewardship efforts.

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

The aim: to study the etiological structure of acute respiratory infections in children aged 3 to 12 hospitalized in the early stages of the disease in the department of respiratory infections of the children’s hospital, and to reveal the features of their clinical course and the timing of DNA / RNA elimination of respiratory viruses from nasal secretions, depending on the method of therapy. Materials and methods: 100 children with acute respiratory infections aged 3 to 12 years were monitored. The nasal secrets on the DNA / RNA of respiratory viruses were studied by PCR. Depending on the method of therapy, patients were divided into 2 groups: patients of group 1 (comparison) received basic treatment (without the use of antiviral drugs), in patients of the 2nd group (main), along with basal therapy, the drug was used umifenovir in a 5-day course at the ageappropriate dosage. Results: In the etiologic structure of ARVI in children from 3 to 12 years, the leading place was taken by rhinovirus, influenza and metapneumovirus infections (isolated – 18%, 19% and 20% respectively, in the form of a mixed infection – 11%). The main syndromic diagnosis at the height of the disease was rhinopharyngitis. Complications were observed in 42% of cases, as often as possible with flu – 53% of cases. Features of metapneumovirus infection in children of this age group were: predominance of non-severe forms of the disease in the form of acute fever with symptoms of rhinopharyngitis, as well as a small incidence of lower respiratory tract infections. The use of the drug umiphenovir in children with acute respiratory viral infections of various etiologies contributed to significantly faster elimination of viral DNA / RNA from the nasal secretion, which was accompanied by a ecrease in the duration of the main clinical and hematological symptoms of the disease, a decrease in the incidence of complications, and reduced the duration of stay in hospital. Conclusion: application of modern molecular genetic methods of diagnostics made it possible to identify the leading role of influenza, metapneumovirus and rhinovirus infections in the etiology of acute respiratory viral infection in patients aged 3 to 12 years, and to determine a number of clinical features characteristic of this age group. The results of the study testify to the effectiveness of umiphenovir in the treatment of children with acute respiratory viral infections of various etiologies and allow us to recommend this drug as an effective and safe etiotropic agent.

AbstractImportanceThe mechanisms driving the recent decline in outpatient antibiotic prescribing are unknown.ObjectiveTo estimate the extent to which reductions in the number of antibiotic prescriptions filled per outpatient visit (stewardship) and reductions in the monthly rate of outpatient visits (observed disease) for infectious disease conditions each contributed to the decline in annual outpatient antibiotic prescribing rate in Massachusetts between 2011 and 2015.DesignOutpatient medical and pharmacy claims from the Massachusetts All-Payer Claims Database were used to estimate rates of antibiotic prescribing and outpatient visits for 20 medical conditions and their contributions to the overall decline in antibiotic prescribing. Trends were compared to those in the National Ambulatory Medical Care Survey (NAMCS).SettingOutpatient visits in Massachusetts between January 2011 and September 2015.Participants5,075,908 individuals with commercial health insurance or Medicaid in Massachusetts under the age of 65 and 495,515 patients included in NAMCS.Main outcomes and measuresThe number of antibiotic prescriptions avoided through reductions in observed disease and reductions in per-visit prescribing rate per medical condition.ResultsBetween 2011 and 2015, the January antibiotic prescribing rate per 1,000 individuals in Massachusetts declined by 18.9% and the July antibiotic prescribing rate declined by 13.6%. The mean prescribing rate for children under 5 declined by 42.8% (95% CI 21.7%, 59.4%), principally reflecting reduced wintertime prescribing. The monthly rate of outpatient visits per 1,000 individuals in Massachusetts declined (p < 0.05) for respiratory infections and urinary tract infections. Nationally, visits for medical conditions that merit an antibiotic prescription also declined between 2010 and 2015. Of the estimated 358 antibiotic prescriptions per 1,000 individuals avoided over the study period in Massachusetts, 59% (95% CI 54%, 63%) were attributable to reductions in observed disease and 41% (95% CI 37%, 46%) to reductions in prescribing per outpatient visit.Conclusions and relevanceThe decline in antibiotic prescribing in Massachusetts was driven by a decline in observed disease and improved antibiotic stewardship, with a contemporaneous reduction in visits for conditions prompting antibiotics observed nationally. A focus on infectious disease prevention should be considered alongside antibiotic stewardship as a means to reduce antibiotic prescribing.Key pointsQuestionHow did the separate mechanisms of improved stewardship and reductions in observed disease contribute to a 5-year decline in outpatient antibiotic prescribing in Massachusetts from 2011-2015?FindingsIn an observational analysis of insurance claims, reduced monthly rates of outpatient visits for infectious conditions and reduced probability of prescribing an antibiotic per outpatient visit both contributed to the decline in antibiotic prescribing. An estimated 358 antibiotic prescriptions per 1,000 individuals were avoided over the study period through the two mechanisms, 211 of which were attributable to reductions in outpatient visits and 147 to reduced antibiotic prescribing per visit.MeaningPreventing the need for outpatient visits should be considered alongside antibiotic stewardship as a means of reducing antibiotic prescribing.

Abstract Background: Inappropriate prescribing of antibiotics for acute respiratory infections at primary care level represents the major source of antibiotic misuse in healthcare, and is a major driver for antimicrobial resistance worldwide. In this study we will develop, pilot and evaluate the effectiveness of a comprehensive antibiotic stewardship programme in China’s primary care hospitals to reduce inappropriate prescribing of antibiotics for acute respiratory infections among all ages.Methods: We will use a parallel-group, cluster-randomised, controlled, superiority trial with blinded outcome evaluation but unblinded treatment (providers and patients). We will randomise 34 primary care hospitals from two counties within Guangdong province into the intervention and control arm (1:1 overall ratio) stratified by county (8:9 within-county ratio). In the control arm, antibiotic prescribing and management will continue through usual care. In the intervention arm, we will implement an antibiotic stewardship programme targeting family physicians and patients/caregivers. The family physician components include: 1) training using new operational guidelines, 2) improved management and peer-review of antibiotic prescribing, 3) improved electronic medical records and smart phone app facilitation. The patient/caregiver component involves patient education via family physicians, leaflets and videos. The primary outcome is the proportion of prescriptions for acute respiratory infections (excluding pneumonia) that contain any antibiotic(s). Secondary outcomes will address how frequently specific classes of antibiotics are prescribed, how frequently key non-antibiotic alternatives are prescribed and the costs of consultations. We will conduct a qualitative process evaluation to explore operational questions regarding acceptability, cultural appropriateness and burden of technology use, as well as a cost-effectiveness analysis and a long-term benefit evaluation. The duration of the intervention will be 12 months, with another 24 months post-trial long-term follow-up.Discussion: Our study is one of the first trials to evaluate the effect of an antibiotic stewardship programme in primary care settings in a low- or middle-income country (LMIC). All intervention activities will be designed to be embedded into routine primary care with strong local ownership. Through the trial we intend to impact on clinical practice and national policy in antibiotic prescription for primary care facilities in rural China and other LMICs.Trial registration: ISRCTN, ISRCTN96892547.

Background Telemedicine, which allows physicians to assess and treat patients via real-time audiovisual conferencing, is a rapidly growing modality for providing medical care. Antibiotic stewardship is one important measure of care quality, and research on antibiotic prescribing for acute respiratory infections in direct-to-consumer telemedicine has yielded mixed results. We compared antibiotic prescription rates for acute respiratory infections in two groups treated by telemedicine: (1) patients treated via a direct-to-consumer telemedicine application and (2) patients treated via telemedicine while physically inside the emergency department. Methods We included direct-to-consumer telemedicine and emergency department telemedicine visits for patients 18 years and older with physician-coded International Classification of Diseases, Tenth Revision acute respiratory infection diagnoses between November 2016 and December 2018. Patients in both groups were seen by the same emergency department faculty working dedicated telemedicine shifts. We compared antibiotic prescribing rates for direct-to-consumer telemedicine and emergency department telemedicine visits before and after adjustment for age, sex, and diagnosis. Results We identified a total of 468 acute respiratory infection visits: 191 direct-to-consumer telemedicine visits and 277 emergency department telemedicine visits. Overall, antibiotics were prescribed for 47% of visits (59% of direct-to-consumer telemedicine visits vs 39% of emergency department telemedicine visits; odds ratio 2.23; 95% confidence interval 1.53–3.25; P < 0.001). The difference in antibiotic prescribing rates remained significant after adjustment for age, sex, and diagnosis (odds ratio 2.49; 95% confidence interval 1.65–3.77; P < 0.001). Conclusion Patients seen by the same group of physicians for acute respiratory infection were significantly more likely to be prescribed antibiotics by direct-to-consumer telemedicine care compared with telemedicine care in the emergency department. This work suggests that contextual factors rather than evaluation over video may contribute to differences in antibiotic stewardship for direct-to-consumer telemedicine encounters.

AbstractObjectiveTo assess the status of antibiotic prescribing in the ambulatory setting for adult patients with acute respiratory infections (ARIs) and to identify opportunities and barriers for outpatient antibiotic stewardship programs (ASPs).DesignMixed methods including point prevalence using chart reviews, surveys, and collaborative learning.SettingHospital-owned clinics in the New York City area.Participants/PatientsIn total, 31 hospital-owned clinics from 9 hospitals and health systems participated in the study to assess ARI prescribing practices for patients >18 years old.InterventionsEach clinic performed a survey of current stewardship practices, retrospective chart reviews of prescribing in 30 randomly selected ARI patients from October 2015 to March 2016, and surveys of provider characteristics and knowledge. Clinics participated in collaborative learning with peers and experts in antibiotic stewardship and collected data from June 2016 to August 2016. Sites received data reports by individual clinic, aggregated by hospital, and were compared among participating clinics.ResultsFew sites had outpatient stewardship activities. The retrospective review of 1,004 ARI patients revealed that 37.3% of ARI patients received antibiotics, with significant variation in prescribing practices among sites (17.4%–71.0%; P<.001). Macrolides were the most commonly prescribed antibiotics. Most of the 302 respondents recognized the need for tools to assist in prescribing.ConclusionsThis collaborative study establishes a baseline assessment of the status of outpatient ASPs in New York City. It provides hospitals, health systems, and individual clinics with specific data to inform their development of stewardship interventions targeting ARIs.

Acute respiratory tract infections are diseases of the upper or lower respiratory tract, which can cause a wide spectrum of diseases ranging from asymptomatic or mild infections to deadly diseases. The high cases of acute respiratory infections in East Muntoi Village are caused by the arrival of the dry season which causes a lot of dust and hot weather as well as the lack of public knowledge about acute respiratory infections. The aim of this service is to increase the knowledge of the people of Muntoi Timur Village, Passi Barat District, Bolaang Mongondow Regency, about acute respiratory infections. This community service is carried out in Muntoi Timur Village, Passi Barat District with the target of hamlets 04 and 05. The methods used are phased from the planning (pre-test), the implementation phase (health education) and the evaluation stage (post-test). The results of this activity are increased public knowledge about the understanding, causes, risk factors, symptoms, prevention and management of acute respiratory infections. It is suggested that the active role of health workers be needed to always provide health education to the community related to acute respiratory infections, so that the community can improve their health independently.
