Aguilar AG, Canals PC, Tian M, Miller KA, Piper BJ. Decreases and Pronounced Geographic Variability in Antibiotic Prescribing in Medicaid. PHARMACY 2024; 12:46. [PMID: 38525726 PMCID: PMC10961814 DOI: 10.3390/pharmacy12020046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/15/2024] [Accepted: 02/18/2024] [Indexed: 03/26/2024] Open
Abstract
Antibiotic resistance is a persistent and growing concern. Our objective was to analyze antibiotic prescribing in the United States (US) in the Medical Expenditure Panel System (MEPS) and to Medicaid patients. We obtained MEPS prescriptions for eight antibiotics from 2013 to 2020. We extracted prescribing rates per 1000 Medicaid enrollees for two years, 2018 and 2019, for four broad-spectrum (azithromycin, ciprofloxacin, levofloxacin, and moxifloxacin) and four narrow-spectrum (amoxicillin, cephalexin, doxycycline, and trimethoprim-sulfamethoxazole) antibiotics. Antibiotic prescriptions in MEPS decreased from 2013 to 2020 by 38.7%, with a larger decline for the broad (-53.7%) than narrow (-23.5%) spectrum antibiotics. Antibiotic prescriptions in Medicaid decreased by 6.7%. Amoxicillin was the predominant antibiotic, followed by azithromycin, cephalexin, trimethoprim-sulfamethoxazole, doxycycline, ciprofloxacin, levofloxacin, and moxifloxacin. Substantial geographic variation in prescribing existed, with a 2.8-fold difference between the highest (Kentucky = 855/1000) and lowest (Oregon = 299) states. The South prescribed 52.2% more antibiotics (580/1000) than the West (381/1000). There were significant correlations across states (r = 0.81 for azithromycin and amoxicillin). This study identified sizable disparities by geography in the prescribing rates of eight antibiotics with over three-fold state-level differences. Areas with high prescribing rates, particularly for outpatients, may benefit from stewardship programs to reduce potentially unnecessary prescribing.

Resistance pattern of isolated microorganisms from 783 clinical specimen cultures in patients admitted to Yasuj Educational Hospitals, Iran. BMC Microbiol 2023; 23:205. [PMID: 37528350 PMCID: PMC10394882 DOI: 10.1186/s12866-023-02952-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Accepted: 07/19/2023] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND Infectious diseases are still one of the leading causes of morbidity and mortality in resource-limited settings. Serious infection caused mostly by gram-negative pathogens causes significant morbidity. According to the Centers for Disease Control and Prevention, antimicrobial resistance kills over 700,000 people worldwide. Antibiotic resistance is on the rise, and as a consequence, serious public health issues are arising. The present study investigated isolated clinical samples from Yasuj teaching hospitals to determine the antimicrobial resistance profile to various antibiotics. MATERIALS AND METHODS Microbial isolates regarding cultures from urine, blood, wound, abdominal tap, throat, stool, cerebrospinal fluid, endotracheal tube, sputum, skin lesion, nasal, and mouth secretion were collected from patients admitted to hospitals affiliated with Yasuj teaching hospitals. Antibiotic susceptibility profiles were determined by using the Kirby-Bauer disc diffusion method. Data were tabulated and analyzed with SPSS version 26.0. RESULTS A total of 783 samples were evaluated in our study, with an average of 30.6 years and 54.5% female patients. Most of the bacterial isolates were gram-negative (64.2%). The majority of cultures were Escherichia coli (49.9%), mainly among urine samples (64.2%). The frequency distribution of norfloxacin antibiotic resistance was more common in internal medicine (66.7%), infectious (63.6%), and emergency wards (58.8%). The frequency distribution of penicillin antibiotic resistance was statistically significant in different wards. All cases of oxacillin were resistant. CONCLUSION Our data showed a high level of antibiotic resistance among bacterial isolates in our center. Considering widespread empirical antibiotic therapy in Iran, the rate of increasing resistance to common antibiotics prescribed for ambulatory and hospitalized patients is concerning. We recommend providing more strict guidelines and policies to control the overuse and overprescription of antimicrobials by health policy-making organizations.

Abstract
Background Invasive fungal infections carry a substantial risk of mortality and morbidity. Azole antifungals are used in the treatment of such infections; however, their extensive use can lead to the emergence of antifungal resistance and increased costs to patients and healthcare systems. The aim of this study is to evaluate trends in these antifungals use and costs. Methods The secular and regional trends of outpatient azole antifungals were analyzed using Medicare Part D Prescriber Public Use Files for the years 2013-2020. The total days supply (TDS), total drug cost (TDC) per 100 000 enrollees, and cost per day (CPD) were evaluated. Results The azole antifungal TDS for Medicare Part D enrollees increased by 12% between 2013 and 2020, and increases were noted for each azole. Southern US regions had the highest TDS, with Arizona having the highest TDS among US states in 2020. Cost analysis showed that TDC of all azoles has increased by 93% over the years, going up from $123 316 in 2013 to $238 336 per 100 000 enrollees in 2020. However, CPD showed an increase only for fluconazole and isavuconazole, with CPD of $1.62 per day and $188.30 per day, respectively. Conclusions Combined azole antifungal prescriptions TDS increased among Medicare Part D enrollees. The trend in CPD was mixed, whereas overall costs consistently increased over the same period. Such findings provide an insight into the impact of azole antifungal prescriptions, and increasing use could foreshadow more antifungal resistance. Continued studies to evaluate different prescribers' trends are warranted.

Abstract
BACKGROUND Z-drugs are nonbenzodiazepine hypnotics used for sleep initiation and maintenance; these drugs increase the risk of fall-related injuries in older adults. The American Geriatrics Society's Beers criteria classifies Z-drugs as high-risk and strongly recommends avoiding prescribing Z-drugs to older adults due to adverse effects. The study objectives were to determine the prevalence of Z-drug prescribing among Medicare Part D patients and identify state or specialty-dependent prescribing differences. This study also aimed to determine prescribing patterns of Z-drugs to Medicare patients. METHODS Z-drug prescription data was extracted from the Centers for Medicare and Medicaid Services State Drug Utilization Data for 2018. For all 50 states, the number of prescriptions per 100 Medicare enrollees and days-supply per prescription was determined. The percentage of total prescriptions prescribed by each specialty and the average number of prescriptions per provider within each specialty was also determined. RESULTS Zolpidem was the most prescribed Z-drug (95.0%). Prescriptions per 100 enrollees were significantly high in Utah (28.2) and Arkansas (26.7) and significantly low in Hawaii (9.3) relative to the national average (17.5). Family medicine (32.1%), internal medicine (31.4%), and psychiatry (11.7%) made up the largest percentages of total prescriptions. The number of prescriptions per provider was significantly high among psychiatrists. DISCUSSION Contrary to the Beers criteria, Z-drugs are prescribed to older adults at high rates.

Abstract
BACKGROUND The incidence of antibiotic-related diarrhea (AAD) is high in older adults. AIM To examine the gut microbiota changes in older adults who received antibiotics to identify the microbial signatures associated with antibiotic use and AAD. METHODS A nested prospective observational cohort study was conducted between December 2019 and June 2021 in patients ≥ 65 years old at Huashan Hospital affiliated with Fudan University. The patients were grouped as antibiotic-treated (HA group) and no antibiotics (HC group); the HA group was subdivided as with vs. without AAD. Fecal samples were collected at admission (i.e., before eventual antibiotics) and after 7 days. RESULT Thirty-eight and 19 participants were included in the HA and HC groups. There were significant differences in gut microbiota between the HA after antibiotics vs. HC groups, with a higher Firmicutes/Bacteroidetes ratio. Before antibiotics in the HA group, the relative abundances of Akkermansia and Alistipes were lower in the AAD subgroup than the no-AAD subgroup, while the relative abundance of Actinomyces was higher. After antibiotics in the HA group, specific bacterial species were decreased in the AAD subgroup compared with the no-AAD subgroup. Among HA participants without probiotics, the abundance of Akkermansia in the patients without AAD was higher than in the patients with AAD at baseline (P = 0.007). CONCLUSION Patients with or without AAD have different gut microbiota compositions before antibiotics. Antibiotics can lead to dysbiosis, with a decrease in beneficial bacteria and an increase in Enterococcus.

Abstract
Recurrent Clostridioides difficile infection (RCDI) causes an increased burden on the healthcare system. We calculated RCDI incidence and identified factors associated with RCDI cases in New Haven County, Connecticut, USA, during 2015-2020 by using data from population-based laboratory surveillance. A subset of C. difficile cases had complete chart reviews conducted for RCDI and potentially associated variables. RCDI was defined as a positive C. difficile specimen occurring 2-8 weeks after incident C. difficile infection. We compared cases with and without RCDI by using multiple regression. RCDI occurred in 12.0% of 4,301 chart-reviewed C. difficile cases, showing a U-shaped time trend with a sharp increase in 2020, mostly because of an increase in hospital-onset cases. Malignancy (odds ratio 1.51 [95% CI 1.11-2.07]) and antecedent nitrofurantoin use (odds ratio 2.37 [95% CI 1.23-4.58]) were medical risk factors for RCDI. The 2020 increase may reflect the impact of the COVID-19 pandemic.

Abstract
Background: Pediatric acute respiratory tract infections (ARTIs) were a common reason for commercial direct-to-consumer (DTC) telemedicine use before the COVID-19 pandemic, but the factors associated with this use are unknown. Objective: To identify child and family factors associated with use of commercial DTC telemedicine for ARTIs in 2018-2019. Methods: We performed a retrospective cohort analysis of claims data from the Optum Clinformatics® Data Mart Database. Among children with ARTI visits, we fitted logit models to examine child and family characteristics associated with DTC telemedicine use. Results: Of 660,725 children with ARTI visits, 12,944 (2.0%) had ≥1 commercial DTC telemedicine encounter. The odds of DTC telemedicine use were higher for children with age ≥12 years, lower parent educational attainment, higher household income, white non-Hispanic race/ethnicity, and residency in the West South Central census division. Conclusion: In 2018-2019, commercial DTC telemedicine use varied with child age, child race/ethnicity parent educational attainment, household income, and geography.

A retrospective review of antibiotic use for acute respiratory infections in urgent-care patients. ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2022; 2:e189. [PMID: 36505944 PMCID: PMC9727505 DOI: 10.1017/ash.2022.337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 10/20/2022] [Accepted: 10/22/2022] [Indexed: 12/09/2022]
Abstract
Objective We examined the use of antibiotics for acute respiratory infections in an urgent-care setting. Design Retrospective database review. Setting The study was conducted in 2 urgent-care clinics staffed by academic emergency physicians in San Diego, California. Patients Visits for acute respiratory infections were identified based on presenting complaints. Methods The primary outcome was a discharge prescription for an antibiotic. The patient and provider characteristics that predicted this outcome were analyzed using logistic regression. The variation in antibiotic prescriptions between providers was also analyzed. Results In total, 15,160 visits were analyzed. The patient characteristics were not predictive of antibiotic treatment. Physicians were more likely than advanced practice practitioners to prescribe antibiotics (1.31; 95% confidence interval [CI], 1.21-1.42). For every year of seniority, a provider was 1.03 (95% CI, 1.02-1.03) more likely to prescribe an antibiotic. Although the providers saw similar patients, we detected significant variation in the antibiotic prescription rate between providers: the mean antibiotic prescription rate within the top quartile was 54.3% and the mean rate in the bottom quartile was 21.7%. Conclusions The patient and provider characteristics we examined were either not predictive or were only weakly predictive of receiving an antibiotic prescription for acute respiratory infection. However, we detected a marked variation between providers in the rate of antibiotic prescription. Provider differences, not patient differences, drive variations in antibiotic prescriptions. Stewardship efforts may be more effective if directed at providers rather than patients.

Abstract
BACKGROUND Benzodiazepines, opioids, proton-pump inhibitors (PPIs), and antibiotics are frequently prescribed inappropriately by primary care physicians (PCPs), without sufficient consideration of alternative options or adverse effects. We hypothesized that distinct groups of PCPs could be identified based on their propensity to prescribe these medications. OBJECTIVE To identify PCP groups based on their propensity to prescribe benzodiazepines, opioids, PPIs, and antibiotics, and patient and PCP characteristics associated with identified prescribing patterns. DESIGN Retrospective cohort study using VA data and latent class regression analyses to identify prescribing patterns among PCPs and examine the association of patient and PCP characteristics with class membership. PARTICIPANTS A total of 2524 full-time PCPs and their patient panels (n = 2,939,636 patients), from January 1, 2017, to December 31, 2018. MAIN MEASURES We categorized PCPs based on prescribing volume quartiles for the four drug classes, based on total days' supply dispensed of each medication by the PCP to their patients (expressed as days' supply per 1000 panel patient-days). We used latent class analysis to group PCPs based on prescribing and used multinomial logistic regression to examine patient and PCP characteristics associated with latent class membership. KEY RESULTS PCPs were categorized into four groups (latent classes): low intensity (23% of cohort), medium-intensity overall/high-intensity PPI (36%), medium-intensity overall/high-intensity opioid (20%), and high intensity (21%). PCPs in the high-intensity group were predominantly in the highest quartile of prescribers for all four drugs (68% in the highest quartile for benzodiazepine, 86% opioids, 64% PPIs, 62% antibiotics). High-intensity PCPs (vs. low intensity) were substantially less likely to be female (OR: 0.30, 95% CI: 0.21-0.42) or practice in the northeast versus other census regions (OR: 0.10, 95% CI: 0.06-0.17). CONCLUSIONS VA PCPs can be classified into four clearly differentiated groups based on their prescribing of benzodiazepines, opioids, PPIs, and antibiotics, suggesting an underlying typology of prescribing. High-intensity PCPs were more likely to be male.

Abstract
BACKGROUND Utilization management policies are pervasive in the Medicare Part D program. We assess the effect of utilization management restrictions in the Medicare Part D program on the quality of care in two clinical areas - community-acquired pneumonia (CAP) and urinary tract infections (UTI). METHODS In this study, we identified new cases of CAP and UTI from Medicare claims data from 2010 to 2016. We assessed the relationship between exposure to utilization management for antibiotic medications suitable for treating these conditions and adverse health outcomes, based on the Agency for Healthcare Research and Quality prevention quality indicators. RESULTS We identified 147,526 cases of CAP and 632,407 UTI cases in our data. In these samples, the adverse event rate varied from 3.6 to 5.7%. The probability of an adverse event increased by 0.75 (p = 0.061) percentage points for each ten percentage point increase in exposure to quantity limits (one form of utilization management) among people with CAP. There was no relationship between utilization management and adverse events in the UTI cohort. CONCLUSIONS In some circumstances, exposure to utilization management policies-particularly quantity limits-may adversely affect health.

[PMID: 35218864 DOI: 10.1016/j.urology.2022.01.048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 12/19/2021] [Accepted: 01/19/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVE To determine exposure rates to antibiotics prior to radical cystectomy and determine if there is correlation with post-operative infections. METHODS AND MATERIALS 2248 patients were identified in the 2016 SEER-Medicare linkage who underwent radical cystectomy between 2008 and 2014 with complete prescription information. An outpatient prescription for an antibiotic within 30 days prior to cystectomy was considered exposure. Antibiotic class and combinations were recorded. Postoperative infectious diagnoses and readmissions were tabulated within 30 days of cystectomy. RESULTS Fifty one percent of patients (n = 1149) were prescribed an outpatient antibiotic prior to cystectomy. Patients receiving antibiotics were more likely to be female (31% vs 25%, P < .01) and had been diagnosed with an infection (17% vs 11%, P < .01). Antibiotic bowel prophylaxis was prescribed to 42% of patients receiving antibiotics. Postoperatively, the exposure group had higher rates of any infection, (56% vs 51% P < .01) and UTI (36% vs 31% P < .01). All-cause readmission within 30 days was higher in the exposure cohort (26% vs 22%, P = .02) Multivariable logistic regression showed outpatient preoperative antibiotics were an independent risk factor for any infection (HR 1.19, P < .05) and readmission (hazards ratio 1.24, P = .03) in the 30 days after radical cystectomy. CONCLUSION Outpatient antibiotic use prior to radical cystectomy is common and may be associated with increased risk of postoperative infection and readmission. Antibiotic use prior to radical cystectomy should be examined as a modifiable factor to decrease post-operative morbidity.

Abstract
IMPORTANCE In 2013 and 2016, the US Food and Drug Administration (FDA) issued warnings and recommended limited use of fluoroquinolones for patients with certain acute conditions. It is not clear how prescribers have responded to these warnings. OBJECTIVE To analyze changes in prescribing of fluoroquinolones after the 2013 and 2016 FDA warnings and to examine the physician characteristics associated with these changes. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study used Medicare administrative claims data on Medicare fee-for-service beneficiaries and OneKey data on physicians and their organizations from January 1, 2011, to December 31, 2017. The sample was restricted to outpatient visits for sinusitis, bronchitis, and uncomplicated urinary tract infections. An interrupted time series approach was used to analyze the changes in the prescription rate after each FDA warning. Data analysis was performed between January 1, 2011, and December 31, 2017. INTERVENTIONS Two FDA black box warnings released in August 2013 and July 2016. MAIN OUTCOMES AND MEASURES The main outcome was an indicator for fluoroquinolone prescriptions in 3 periods: before the 2013 warning (baseline period), after the 2013 warning but before the 2016 warning (postwarning period 1), and after the 2016 warning (postwarning period 2). RESULTS The sample comprised 1 238 397 unique patients with a total of 2 720 071 outpatient acute care visits. Of this sample, 848 360 were women (68.5%), and the mean (SD) age was 69.7 (12.6) years. The immediate prescribing levels of fluoroquinolones in postwarning period 1 increased by 3.42 percentage points (95% CI, 3.23-3.62; P < .001) and declined by -0.77 percentage points (95% CI, -1.00 to -0.54; P < .001) in postwarning period 2. The prescribing trend increased by 0.08 percentage points per month (95% CI, 0.08-0.10; P < .001) in postwarning period 1 and 0.06 percentage points per month (95% CI, 0.04-0.08; P < .001) in postwarning period 2. In postwarning period 1, the prescribing levels for physicians who were affiliated with hospitals with a top 10th percentile case mix index vs those without such affiliation decreased by -1.13 percentage points (95% CI, -1.92 to -0.34; P = .005), whereas the levels for primary care physicians declined by -1.34 percentage points (95% CI, -1.78 to -0.88; P < .001) compared with non-primary care physicians in postwarning period 2. Physicians at teaching hospitals were the only ones who showed a decline in prescribing trend in postwarning period 1. CONCLUSIONS AND RELEVANCE This cross-sectional study found an overall decline in prescribing of fluoroquinolones after the release of FDA warnings. Understanding the association of physician and organizational characteristics with fluoroquinolone prescribing behavior may ultimately help to identify mechanisms to improve de-adoption.

Abstract
Background: Little is known about antibiotic prescribing on hospice admission despite known risks and limited evidence for potential benefits. Objective: To describe the frequency and characteristics of patients prescribed antibiotics on hospice admission. Design: Cross-sectional study. Subjects: Adult (age ≥18 years) decedents of a national, for-profit hospice chain across 19 U.S. states who died between January 1, 2017 and December 31, 2019. Measures: The primary outcome was having an antibiotic prescription on hospice admission. Patient characteristics of interest were demographics, hospice referral location, hospice care location, census region, primary diagnosis, and infectious diagnoses on admission. We used multivariable logistic regression to quantify associations between study variables. Results: Among 66,006 hospice decedents, 6080 (9.2%) had an antibiotic prescription on hospice admission. Fluoroquinolones (22%) were the most frequently prescribed antibiotic class. Patients more likely to have an antibiotic prescription on hospice admission included those referred to hospice care from the hospital (adjusted odds ratio [aOR] 1.13, 95% confidence interval [CI] 1.00-1.29) compared with an assisted living facility, those receiving hospice care in a private home (aOR 3.85, 95% CI 3.50-4.24), nursing home (aOR 3.65, 95% CI 3.24-4.11), assisted living facility (aOR 4.04, 95% CI 3.51-4.64), or hospital (aOR 2.43, 95% CI 2.18-2.71) compared with inpatient hospice, and those with a primary diagnosis of liver disease (aOR 2.23, 95% CI 1.82-2.74) or human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (aOR 3.89, 95% CI 2.27-6.66) compared with those without these diagnoses. Conclusions: Approximately 9% of hospice patients had an antibiotic prescription on hospice admission. Patients referred to hospice from a hospital, those receiving care in a noninpatient hospice facility, and those with liver disease or HIV/AIDS were more likely to have an antibiotic prescription. These results may inform future antimicrobial stewardship interventions among patients transitioning to hospice care.

Abstract
INTRODUCTION The objective of this study is to identify county-level characteristics that may be high-impact targets for opioid and antibiotic interventions to improve dental prescribing. METHODS Prescriptions during 2012-2017 were extracted from the IQVIA Longitudinal Prescription database. Primary outcomes were yearly county-level antibiotic and opioid prescribing rates. Multivariable negative binomial regression identified associations between prescribing rates and county-level characteristics. All analyses occurred in 2020. RESULTS Over time, dental opioid prescribing rates decreased by 20% (from 4.02 to 3.22 per 100 people), whereas antibiotic rates increased by 5% (from 6.85 to 7.19 per 100 people). Higher number of dentists per capita, higher proportion of female residents, and higher proportion of residents aged <65 years were associated with increased opioid rates. Relative to location in the West, location in the Northeast (59%, 95% CI=52, 65) and Midwest (64%, 95% CI=60, 70) was associated with lower opioid prescribing rates. Higher clinician density, median household income, proportion female, and proportion White were all independently associated with higher antibiotic rates. Location in the Northeast (149%, 95% CI=137, 162) and Midwest (118%, 95% CI=111, 125) was associated with higher antibiotic rates. Opioid and antibiotic prescribing rates were positively associated. CONCLUSIONS Dental prescribing of opioids is decreasing, whereas dental antibiotic prescribing is increasing. High prescribing of antibiotics is associated with high prescribing of opioids. Strategies focused on optimizing dental antibiotics and opioids are needed given their impact on population health.

Abstract
BACKGROUND The role of changes in gut microflora on upper gastrointestinal (UGI) perforations is not known. We conducted a retrospective case-control study to examine the relationship between antibiotic exposure-a proxy for microbiome modulation-and UGI perforations in a national sample. METHODS We queried a 5% random sample of Medicare (2009-2013) to identify patients ≥ 65 years old hospitalized with UGI (stomach or small intestine) perforations using International Classification of Diseases diagnosis codes. Cases with UGI perforations were matched with 4 controls, each based on age and sex. Exposure to outpatient antibiotics (0-30, 31-60, 61-90 days) prior to case patients' index hospitalization admission data was determined with Part D claims. Univariate and multivariable regression analyses were performed to evaluate the effect of antibiotic exposure on UGI perforation. RESULTS Overall, 504 cases and 2016 matched controls were identified. Compared to controls, more cases had antibiotic exposure 0-30 days (19% vs. 3%, p < 0.001) and 31-60 days (5% vs. 2%, p < 0.001) prior to admission. In adjusted analyses, antibiotic exposure 0-30 days prior to admission was associated with 6.8 increased odds of an UGI perforation (95% CI 4.8, 9.8); 31-60 days was associated with 1.9 increased odds (95% CI 1.1, 3.3); and 61-90 days was associated with 3.7 increased odds (95% CI 2.0, 6.9). CONCLUSIONS Recent outpatient antibiotic use, in particular in the preceding 30 days, is associated with UGI perforation among Medicare beneficiaries. Exposure to antibiotics, one of the most modifiable determinants of the microbiome, should be minimized in the outpatient setting.

Abstract
This study aimed to determine the differences in antibiotic usage patterns in the treatment of acute pyelonephritis according to hospital type and region in Korea.The claims database of the Health Insurance Review and Assessment Service in Korea was used to select patients with the International Classification of Diseases, Tenth Revision code N10 (acute tubulo-interstitial nephritis) or N12 (tubulo-interstitial nephritis, neither acute nor chronic) as the primary discharge diagnosis in 2010-2014. Usage of each class of antibiotics was expressed as the defined daily dose (DDD)/event.The average antibiotic usage per inpatient event was 11.3 DDD. The average antibiotic usage was the highest among patients admitted to tertiary hospitals (13.8 DDD), followed by those admitted to secondary hospitals (11.5 DDD), clinics (10.0 DDD), and primary hospitals (9.8 DDD). According to the geographic analyses, third-generation cephalosporins were highly prescribed in some southern regions; fluoroquinolones and aminoglycosides were highly prescribed in some centrally located regions of the Korean peninsula. The hotspots for carbapenem usage included Seoul and Gyeonggi province cluster and Busan cluster: these regions include the capital city and the second biggest city in Korea, respectively.In conclusion, the antibiotic usage patterns for acute pyelonephritis in Korea differ according to the hospital type and region.

Abstract
BACKGROUND Systemic corticosteroids are not indicated for acute respiratory tract infections yet are nonetheless prescribed in outpatient care. Acute respiratory tract infections are the most common diagnosis in direct-to-consumer telemedicine. The objective of this study was to characterize use of corticosteroids for acute respiratory tract infections in this setting and to assess the association between corticosteroid receipt and patient satisfaction. METHODS Encounters with acute respiratory tract infection patients 18 years and older on a nationwide direct-to-consumer telemedicine platform were conducted by physicians between July 2016 and July 2018. Mixed-effects logistic regression was used to assess differences in the odds of corticosteroid prescription. A second mixed-effects model assessed differences in patient satisfaction by corticosteroid or antibiotic receipt. Adjusted prescribing rates for individual physicians were estimated. Models included diagnoses, patient age and geographic region, physician specialty and geographic region, and antibiotic prescription. RESULTS Of the 85,972 encounters with 465 physicians, 11% resulted in the physician prescribing corticosteroids. The median physician prescribing rate was 4.0% (range: <1%-81%). Corticosteroid receipt was associated with higher satisfaction versus receiving nothing (odds ratio: 2.54; 95% confidence interval: 2.25-2.87). Patients who received both an antibiotic and a corticosteroid reported the highest satisfaction (odd ratio: 3.91; 95% confidence interval: 3.27-4.68). There was no correlation between individual physicians' corticosteroid and antibiotic prescribing rates. CONCLUSIONS Corticosteroid receipt was associated with patient satisfaction. Most physicians rarely prescribed corticosteroids, yet a small number prescribed them frequently. Identification of high-prescribing physicians for educational interventions could reduce use of corticosteroids for acute respiratory tract infections.

Abstract
Elderly people are a particularly important population with regard to antibiotic overuse, using around 50% more antibiotics per capita than younger adults. The aim of this study was to analyze the prevalence, associated factors and evolution over time of antibiotic consumption among the Spanish population aged ≥ 65 years from 2006 to 2017. A descriptive cross-sectional study was conducted using data from the Spanish National Health Survey in 2006, 2011/2012 and 2017, and from the European Health Survey in Spain in 2009 and 2014. The sample consisted of 26,891 non-institutionalized individuals ≥ 65 years. Antibiotic consumption was the dependent variable, and sociodemographic variables, lifestyle habits and health status were analyzed using a logistic regression model. The prevalence of antibiotic consumption was 4.94%, with a marked increase from 2006 (4.64%) to 2017 (5.81%) (p < 0.0001). Higher antibiotic consumption was associated with poor or very poor self-perceived health status, no polypharmacy and not having been in hospital during the previous twelve months, while a lower consumption was linked to being limited but not severely due to a health problem and not being at all limited.

Abstract
Background Antimicrobial overuse and misuse of broad-spectrum antibiotics increases the risk for antimicrobial resistance. Investigating unwarranted variation in antibiotic prescription has therefore gained global priority. Methods We examined recent time trends in the utilization of narrow- and broad-spectrum antibiotics as well as the variation in antibiotic use by sex, age, and municipality of residence. Complete individual-level data on all redeemed out-of hospital prescriptions for antibiotics in the entire adult population of Central Denmark (1.3 million inhabitants) was obtained for the period 2006–2015. Results Following an initial increase of 2% between 2006 and 2011, the overall rate of redeemed prescriptions for antibiotics per 1000 person years declined by 17% between 2011 and 2015. Among persons aged over 65 years, the decline in use began later (from 2013) and was less pronounced. Antibiotic use in 2015 remained substantially higher among females (289/1000 person-years) vs. males (182/1000 person-years) and among the very old (520/1000 person-years in >85y old) vs. middle-aged (204/1000 person-years in 45-65y old). A decreasing trend in antibiotic use over time was observed in all municipalities, mainly due to a decrease in narrow-spectrum antibiotics. However, a striking and unexplained 1.6-fold geographical variation in antibiotic use, including tetracyclines, macrolides and fluoroquinolones remained in 2015. Of concern, among females aged ≥65 years and males aged ≥85 years, a continuous increasing trend in broad-spectrum antibiotic use was observed. Conclusions Antibiotic use has decreased almost 20% in Central Denmark after 2011, possibly related to a nationwide antibiotic stewardship program in Denmark. However, substantial geographical variation in antibiotic prescription remains and the use of broad-spectrum antibiotics has increased in adults of older age. Continuous focus on avoiding unnecessary use of broad-spectrum antibiotics is requested.

Abstract
Antibiotic use is a primary driver of antibiotic resistance. However, antibiotic use can be distributed in different ways in a population, and the association between the distribution of use and antibiotic resistance has not been explored. Here, we tested the hypothesis that repeated use of antibiotics has a stronger association with population-wide antibiotic resistance than broadly-distributed, low-intensity use. First, we characterized the distribution of outpatient antibiotic use across US states, finding that antibiotic use is uneven and that repeated use of antibiotics makes up a minority of antibiotic use. Second, we compared antibiotic use with resistance for 72 pathogen-antibiotic combinations across states. Finally, having partitioned total use into extensive and intensive margins, we found that intense use had a weaker association with resistance than extensive use. If the use-resistance relationship is causal, these results suggest that reducing total use and selection intensity will require reducing broadly distributed, low-intensity use.

Abstract
The inappropriate use of antibiotics can increase the likelihood of antibiotic resistance and adverse events. In the United States, nearly a third of antibiotic prescriptions in outpatient settings are unnecessary, and the selection of antibiotics and duration of treatment are also often inappropriate. Evidence shows that antibiotic prescribing is influenced by psychosocial factors, including lack of accountability, perceived patient expectations, clinician workload, and habit. A varied and growing body of evidence, including meta-analyses and randomized controlled trials, has evaluated interventions to optimize the use of antibiotics. Interventions informed by behavioral science-such as communication skills training, audit and feedback with peer comparison, public commitment posters, and accountable justification-have been associated with improved antibiotic prescribing. In addition, delayed prescribing, active monitoring, and the use of diagnostics are guideline recommended practices that improve antibiotic use for some conditions. In 2016, the Centers for Disease Control and Prevention released the Core Elements of Outpatient Antibiotic Stewardship, which provides a framework for implementing these interventions in outpatient settings. This review summarizes the varied evidence on drivers of inappropriate prescription of antibiotics in outpatient settings and potential interventions to improve their use in such settings.

Improvement of gram-negative susceptibility to fluoroquinolones after implementation of a pre-authorization policy for fluoroquinolone use: A decade-long experience. Infect Control Hosp Epidemiol 2018; 39:1419-1424.

Abstract
OBJECTIVE Due to concerns over increasing fluoroquinolone (FQ) resistance among gram-negative organisms, our stewardship program implemented a preauthorization use policy. The goal of this study was to assess the relationship between hospital FQ use and antibiotic resistance. DESIGN Retrospective cohort. SETTING Large academic medical center. METHODS We performed a retrospective analysis of FQ susceptibility of hospital isolates for 5 common gram-negative bacteria: Acinetobacter spp., Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Primary endpoint was the change of FQ susceptibility. A Poisson regression model was used to calculate the rate of change between the preintervention period (1998-2005) and the postimplementation period (2006-2016). RESULTS Large rates of decline of FQ susceptibility began in 1998, particularly among P. aeruginosa, Acinetobacter spp., and E. cloacae. Our FQ restriction policy improved FQ use from 173 days of therapy (DOT) per 1,000 patient days to <60 DOT per 1,000 patient days. Fluoroquinolone susceptibility increased for Acinetobacter spp. (rate ratio [RR], 1.038; 95% confidence interval [CI], 1.005-1.072), E. cloacae (RR, 1.028; 95% CI, 1.013-1.044), and P. aeruginosa (RR, 1.013; 95% CI, 1.006-1.020). No significant change in susceptibility was detected for K. pneumoniae (RR, 1.002; 95% CI, 0.996-1.008), and the susceptibility for E. coli continued to decline, although the decline was not as steep (RR, 0.981; 95% CI, 0.975-0.987). CONCLUSIONS A stewardship-driven FQ restriction program stopped overall declining FQ susceptibility rates for all species except E. coli. For 3 species (ie, Acinetobacter spp, E. cloacae, and P. aeruginosa), susceptibility rates improved after implementation, and this improvement has been sustained over a 10-year period.

[PMID: 30221746 PMCID: PMC7909599 DOI: 10.1111/jgs.15518] [Citation(s) in RCA: 41] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2018] [Revised: 05/19/2018] [Accepted: 06/06/2018] [Indexed: 12/13/2022]
Abstract
OBJECTIVES To characterize antibiotics prescribed to older adults to guide efforts to improve antibiotic use. DESIGN Descriptive analysis. SETTING Ambulatory. PARTICIPANTS Adults aged 65 and older in the United States. MEASUREMENTS Information on outpatient antibiotic prescriptions dispensed for older adults from 2011 to 2014 was extracted from the IQVIA Xponent database. A chi-square trend analysis was conducted to assess annual changes in antibiotic prescribing rates. A descriptive analysis of prescribing rates by antibiotic, age group, sex, state, Census region, and provider specialty was conducted. RESULTS From 2011 to 2014, outpatient antibiotic prescribing rates remained stable in older U.S. adults (P = .89). In 2014, older adults were dispensed 51.6 million prescriptions (1,115 prescriptions/1,000 persons). Persons aged 75 and older had a higher prescribing rate (1,157 prescriptions/1,000 persons) than those aged 65 to 74 (1,084 prescriptions/1,000 persons). Prescribing rates were highest in the South 1228 prescriptions/1,000 persons) and lowest in the West (854 prescriptions/1,000 persons). The most commonly prescribed class was quinolones, followed by penicillins and macrolides. Azithromycin was the most commonly prescribed drug, followed by amoxicillin and ciprofloxacin. Internists and family physicians prescribed 43% of antibiotic courses. CONCLUSION On average, in 2014, U.S. adults aged 65 and older received enough outpatient antibiotic courses for every older adult to receive at least 1. Quinolones and azithromycin are potential targets for assessing the appropriateness of antibiotic prescribing in this population. Interventions to improve use targeting internists and family physicians in the South Census region might have the potential to have the greatest effect.

Abstract
OBJECTIVE To identify temporal trends in outpatient antibiotic use and antibiotic prescribing practice among older adults in a high income country. DESIGN Observational study using United States Medicare administrative claims in 2011-15. SETTING Medicare, a US national healthcare program for which 98% of older adults are eligible. PARTICIPANTS 4.5 million fee-for-service Medicare beneficiaries aged 65 years old and older. MAIN OUTCOME MEASUREMENTS Overall rates of antibiotic prescription claims, rates of potentially appropriate and inappropriate prescribing, rates for each of the most frequently prescribed antibiotics, and rates of antibiotic claims associated with specific diagnoses. Trends in antibiotic use were estimated by multivariable regression adjusting for beneficiaries' demographic and clinical covariates. RESULTS The number of antibiotic claims fell from 1364.7 to 1309.3 claims per 1000 beneficiaries per year in 2011-14 (adjusted reduction of 2.1% (95% confidence interval 2.0% to 2.2%)), but then rose to 1364.3 claims per 1000 beneficiaries per year in 2015 (adjusted reduction of 0.20% over 2011-15 (0.09% to 0.30%)). Potentially inappropriate antibiotic claims fell from 552.7 to 522.1 per 1000 beneficiaries over 2011-14, an adjusted reduction of 3.9% (3.7% to 4.1%). Individual antibiotics had heterogeneous changes in use. For example, azithromycin claims per beneficiary decreased by 18.5% (18.2% to 18.8%) while levofloxacin claims increased by 27.7% (27.2% to 28.3%). Azithromycin use associated with each of the potentially appropriate and inappropriate respiratory diagnoses decreased, while levofloxacin use associated with each of those diagnoses increased. CONCLUSION Among US Medicare beneficiaries, overall antibiotic use and potentially inappropriate use in 2011-15 remained steady or fell modestly, but individual drugs had divergent changes in use. Trends in drug use across indications were stronger than trends in use for individual indications, suggesting that guidelines and concerns about antibiotic resistance were not major drivers of change in antibiotic use.
