Drivers of Geographic Patterns in Outpatient Antibiotic Prescribing in the United States.

In a retrospective, ecological analysis of US medical claims, visit rates explained more of the geographic variation in outpatient antibiotic prescribing rates than per-visit prescribing. Efforts to reduce antibiotic use may benefit from addressing the factors that drive higher rates of outpatient visits, in addition to continued focus on stewardship.

The Effect of COVID-19 Vaccination on Outpatient Antibiotic Prescribing in Older Adults: A Self-Controlled Risk-Interval Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccination has been associated with reduced outpatient antibiotic prescribing among older adults with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We assessed the impact of COVID-19 vaccination on outpatient antibiotic prescribing in the broader population of older adults, regardless of SARS-CoV-2 infection status. METHODS: We included adults aged ≥65 years who received their first, second, and/or third COVID-19 vaccine dose from December 2020 to December 2022. We used a self-controlled risk-interval design and included cases who received an antibiotic prescription 2-6 weeks before vaccination (pre-vaccination or control interval) or after vaccination (post-vaccination or risk interval). We used conditional logistic regression to estimate the odds of being prescribed (1) any antibiotic, (2) a typical "respiratory" infection antibiotic, or (3) a typical "urinary tract" infection antibiotic (negative control) in the post-vaccination interval versus the pre-vaccination interval. We accounted for temporal changes in antibiotic prescribing using background monthly antibiotic prescribing counts. RESULTS: 469 923 vaccine doses met inclusion criteria. The odds of receiving any antibiotic or a respiratory antibiotic prescription were lower in the post-vaccination versus pre-vaccination interval (aOR, .973; 95% CI, .968-.978; aOR, .961; 95% CI, .953-.968, respectively). There was no association between vaccination and urinary antibiotic prescriptions (aOR, .996; 95% CI, .987-1.006). Periods with high (>10%) versus low (<5%) SARS-CoV-2 test positivity demonstrated greater reductions in antibiotic prescribing (aOR, .875; 95% CI, .845-.905; aOR, .996; 95% CI, .989-1.003, respectively). CONCLUSIONS: COVID-19 vaccination was associated with reduced outpatient antibiotic prescribing in older adults, especially during periods of high SARS-CoV-2 circulation.

Antibiotic Prescribing Patterns for Respiratory Tract Illnesses Following the Conclusion of an Education and Feedback Intervention in Primary Care.

BACKGROUND: A study previously conducted in primary care practices found that implementation of an educational session and peer comparison feedback was associated with reduced antibiotic prescribing for respiratory tract diagnoses (RTDs). Here, we assess the long-term effects of this intervention on antibiotic prescribing following cessation of feedback. METHODS: RTD encounters were grouped into tiers based on antibiotic prescribing appropriateness: tier 1, almost always indicated; tier 2, possibly indicated; and tier 3, rarely indicated. A χ2 test was used to compare prescribing between 3 time periods: pre-intervention, intervention, and post-intervention (14 months following cessation of feedback). A mixed-effects multivariable logistic regression analysis was performed to assess the association between period and prescribing. RESULTS: We analyzed 260 900 RTD encounters from 29 practices. Antibiotic prescribing was more frequent in the post-intervention period than in the intervention period (28.9% vs 23.0%, P < .001) but remained lower than the 35.2% pre-intervention rate (P < .001). In multivariable analysis, the odds of prescribing were higher in the post-intervention period than the intervention period for tier 2 (odds ratio [OR], 1.19; 95% confidence interval [CI]: 1.10-1.30; P < .05) and tier 3 (OR, 1.20; 95% CI: 1.12-1.30) indications but was lower compared to the pre-intervention period for each tier (OR, 0.66; 95% CI: 0.59-0.73 tier 2; OR, 0.68; 95% CI: 0.61-0.75 tier 3). CONCLUSIONS: The intervention effects appeared to last beyond the intervention period. However, without ongoing provider feedback, there was a trend toward increased prescribing. Future studies are needed to determine optimal strategies to sustain intervention effects.

Risk factors associated with antibiotic prescriptions for cases of enteric pathogens in Canada, 2015-2019.

Inappropriate antibiotic use is a key driver of antibiotic resistance and one that can be mitigated through stewardship. A better understanding of current prescribing practices is needed to develop successful stewardship efforts. This study aims to identify factors that are associated with human cases of enteric illness receiving an antibiotic prescription. Cases of laboratory-confirmed enteric illness reported to the FoodNet Canada surveillance system between 2015 and 2019 were the subjects of this study. Laboratory data were combined with self-reported data collected from an enhanced case questionnaire that included demographic data, illness duration and symptoms, and antibiotic prescribing. The data were used to build univariable logistic regression models and a multivariable logistic regression model to explore what factors were associated with a case receiving an antibiotic prescription. The final multivariable model identified several factors as being significantly associated with cases being prescribed an antibiotic. Some of the identified associations indicate that current antibiotic prescribing practices include a substantial level of inappropriate use. This study provides evidence that antibiotic stewardship initiatives targeting infectious diarrhoea are needed to optimize antibiotic use and combat the rise of antibiotic resistance.

Evaluation of Local Prescribing Patterns and Antimicrobial Resistance in Women With Acute Pyelonephritis Caused by E. coli.

BACKGROUND: Owing to increasing local Escherichia coli resistance and current guidelines for the treatment of acute pyelonephritis (APN) over 14 years old, an evaluation of local prescribing patterns is warranted. OBJECTIVE: The purpose of this study was to evaluate local prescribing patterns and appropriateness of antibiotics in acute uncomplicated APN. METHODS: This is a retrospective cohort study of female patients aged 18 to 89 years diagnosed with APN and positive urine culture growing E. coli. Exclusion criteria included pregnancy, immunocompromised status, and complicated urinary tract infections. Outcomes included antibiotic appropriateness and its effects on hospital admission, hospital length of stay, and 30-day readmission. RESULTS: Between 2017 and 2022, 308 female patients were diagnosed with APN and had positive urine cultures, with 104 seen only in the emergency department (ED) and 109 admitted to the hospital. Patients seen in the ED had a significant increase in E. coli resistance to discharge antibiotics (12.5% vs 2.8%, P = 0.0070). In those patients discharged on antibiotics resistant to E. coli, significantly more patients returned to the ED in 30 days (31.3% vs 10.7%, P = 0.0155). CONCLUSION AND RELEVANCE: Patients seen only in the ED were more likely to have resistant organisms to discharge antibiotics compared with those admitted to the hospital. Patients discharged on antibiotics resistant to E. coli had a 3-fold increase in returning to the ED within 30 days regardless of admitted location. Follow-up of all cultures should be performed, and patients resistant to discharge antibiotics should be contacted and antibiotic regimens changed.

Ten-year trends of antibiotic prescribing in surgery departments of two private sector hospitals in Central India: a prospective observational study.

BACKGROUND: Inappropriate antibiotic use contributes to the global rise of antibiotic resistance, prominently in low- and middle-income countries, including India. Despite the considerable risk of surgical site infections, there is a lack of antibiotic prescribing guidelines and long-term studies about antibiotic prescribing in surgery departments in India. Therefore, this study aimed to analyse 10 years' antibiotic prescribing trends at surgery departments in two tertiary-care hospitals in Central India. METHODS: Data was prospectively collected from 2008 to 2017 for surgery inpatients in the teaching (TH-15,016) and the non-teaching hospital (NTH-14,499). Antibiotics were classified based on the World Health Organization (WHO) Access Watch Reserve system and analysed against the diagnoses and adherence to the National List of Essential Medicines India (NLEMI) and the WHO Model List of Essential Medicines (WHOMLEM). Total antibiotic use was calculated by DDD/1000 patient days. Time trends of antibiotic prescribing were analysed by polynomial and linear regressions. RESULTS: The most common indications for surgery were inguinal hernia (TH-12%) and calculus of the kidney and ureter (NTH-13%). The most prescribed antibiotics were fluoroquinolones (TH-20%) and 3rd generation cephalosporins (NTH-41%), and as antibiotic prophylaxis, norfloxacin (TH-19%) and ceftriaxone (NTH-24%). Access antibiotics were mostly prescribed (57%) in the TH and Watch antibiotics (66%) in the NTH. Culture and susceptibility tests were seldom done (TH-2%; NTH-1%). Adherence to the NLEMI (TH-80%; NTH-69%) was higher than adherence to the WHOMLEM (TH-77%; NTH-66%). Mean DDD/1000 patient days was two times higher in the NTH than in the TH (185 vs 90). Overall antibiotic prescribing significantly increased in the TH (ß1 =13.7) until 2012, and in the NTH (ß2 =0.96) until 2014, and after that decreased (TH, ß2= -0.01; NTH, ß3= -0.0005). The proportion of Watch antibiotic use significantly increased in both hospitals (TH, ß=0.16; NTH, ß=0.96). CONCLUSION: Total antibiotic use decreased in the last three (NTH) and five years (TH), whereas consumption of Watch antibiotics increased over 10 years in both hospitals. The choice of perioperative antibiotic prophylaxis was often inappropriate and antibiotic prescribing was mostly empirical. The results of this study confirmed the need for antibiotic prescribing guidelines and implementation of antimicrobial stewardship programs.

Outcomes of antibiotic treatment for respiratory infections in children an observational study in primary care.

BACKGROUND: Antibiotic resistance is an increasing global threat, accelerated by both misuse and overuse of antibiotics. Most antibiotics to humans are prescribed in primary care, commonly for respiratory symptoms, and there is a need for research on the usage of and outcomes after antibiotic treatment to counteract antibiotic resistance. OBJECTIVE: To evaluate symptom duration, treatment length, and adverse events of antibiotic treatment in children. DESIGN AND SETTING: Observational study at four out-of-hours services and one paediatric emergency clinic in Norwegian emergency primary care. SUBJECTS: 266 children aged 0 to 6 years with fever or respiratory symptoms. MAIN OUTCOME MEASURES: Duration of symptoms and absenteeism from kindergarten/school, treatment length, and reported adverse events. RESULTS: There were no differences in duration of symptoms, fever or absenteeism when comparing the groups prescribed (30.8%) and not prescribed (69.2%) antibiotics. This lack of difference remained when analysing the subgroup with otitis media.In the group prescribed antibiotics, 84.5% of parents reported giving antibiotics for 5-7 days, and 50.7% reported no difficulties. Adverse events of antibiotics were reported in 42.3% of the cases, the vast majority being gastrointestinal disturbances. CONCLUSION: Children with fever or respiratory symptoms experience similar duration of symptoms and absenteeism regardless of antibiotic treatment. A substantial number of parents reported adverse events when the child received antibiotics. Several parents experienced additional difficulties with the treatment, some ending treatment within day 4. TRIAL REGISTRATION NUMBER: NCT02496559; Results.

Children with fever or respiratory symptoms treated at OOH services experience similar duration of symptoms or absenteeism, regardless of antibiotic treatment.Parents often choose to end antibiotic treatment prematurely due to adverse events, bad taste, or that they find treatment unnecessary.Children often experience adverse events when prescribed antibiotics, mainly gastrointestinal symptoms.

Factors influencing antibiotic prescribing for respiratory tract infections in primary care - a comparison of physicians with different antibiotic prescribing rates.

BACKGROUND: There has been a notable decrease in antibiotic prescribing in the last thirty years in Sweden. Little is known about factors influencing antibiotic prescribing over several years. OBJECTIVE: To compare primary care physicians who, over time, reduced their antibiotic prescribing for respiratory tract infections with those who remained either high or low prescribers regarding potentially influencing factors. DESIGN AND SETTING: A register-based study including all RTI visits in primary care in Region Kronoberg, Sweden 2006-2014. The data were divided into three 3-year periods. SUBJECTS: The data comprised all physicians who had diagnosed at least one RTI for each of the three-year periods. The antibiotic prescribing rate adjusted for the patients' sex and age group was calculated for each physician and period, and based on the change between the first and the third period, the physicians were divided into three prescriber groups: The High Prescribing Group, the Decreasing Prescribing Group, and the Low Prescribing Group. MAIN OUTCOME MEASURES: For the three prescriber groups, we compared factors influencing antibiotic prescribing such as the characteristics of the physicians, their use of point-of-care tests, their choice of diagnoses, and whether the patients returned and received antibiotics. RESULTS: The High Prescribing Group ordered more point-of-care tests, registered more potential bacterial diagnoses, prescribed antibiotics at lower C-reactive protein levels, and prescribed antibiotics more often despite negative group A Streptococci test than in the Low Prescribing Group. The Decreasing Prescribing Group was between the High Prescribing Group and the Low Prescribing Group regarding these variables. The lower prescription rate in the Low Prescribing Group did not result in more return visits or new antibiotic prescriptions within 30 days. CONCLUSION: Point-of-care testing and its interpretation differed between the prescriber groups. Focus on interpreting point-of-care test results could be a way forward in antibiotic stewardship.

High prescribers used antibiotics at lower CRP levels and were more likely to identify a potential bacterial diagnosis.Many physicians reduced their antibiotic prescribing during the study period. Nine out of ten low prescribers remained low prescribers.Seeing a low-prescribing physician did not lead to more return visits or antibiotic changes.

Use of point-of-care tests in pharyngotonsillitis - a registry-based study in primary health care.

BACKGROUND: Point-of-care (POC) tests, including C-reactive protein (CRP) tests and rapid antigen detection tests (RADT) for group A streptococci (GAS), are widely used in Swedish primary health care (PHC). This study quantifies their use in pharyngotonsillitis and explore their association with antibiotic prescribing. MATERIAL AND METHODS: Retrospective data from 2012-2016 in Region Kronoberg, Sweden, included all PHC visits with a pharyngotonsillitis diagnosis. Patient characteristics, test usage and antibiotic prescriptions were linked by visit date and personal identification number. Descriptive statistics were used for POC test analysis. Logistic regression assessed the association between CRP levels and antibiotic prescribing. RESULTS: Of 24,237 visits, 68% included RADT and 36% included a CRP test, with 89% of CRP tests performed alongside RADT. CRP testing was more frequent in patients with negative (56%) than positive RADTs (42%) (p < .001). Overall, 66% of RADTs were positive. Median CRP levels were 23 mg/l for positive RADT and 31 mg/l for negative RADT (p < .001). Antibiotics were prescribed for 95% of positive RADTs and 43% of negative RADTs (p < .001). In patients with negative RADTs, CRP testing was associated with higher antibiotic prescribing (57%) compared to no CRP testing (26%) (p < .001). Among these patients, CRP levels were associated with prescribing (aOR 1.032; 95% CI 1.029-1.035; p < .001), with 50% of prescriptions occuring at CRP levels ≤ 20 mg/l. CONCLUSION: The use of RADTs and the proportion of positive test were higher than expected, indicating inappropriate use and diagnostic bias. CRP testing, contrary to guidelines, was common and associated with increased antibiotic prescribing.

Self-assessed levels of preparedness, engagement willingness and teaching preferences on antibiotic use of medical and pharmacy students in Romanian universities: a cross-sectional study.

BACKGROUND: To effectively support health professionals in optimizing antibiotic prescribing and dispensing, policymakers need to understand how these professionals are trained, feel prepared and want to be educated. The study aimed to assess the current situation and explore potential improvements in antibiotic use among future health professionals in Romania by: (i) evaluating their self-assessed preparedness on antibiotic-related topics, (ii) understanding their perceptions of their role in antibiotic stewardship, and (iii) gathering their recommendations for optimizing antibiotic use. METHODS: A survey of students' self-assessment of technical preparedness, engagement willingness, expectations, teaching preferences, training received and evolution of situation in Romania. Overall, 41 and 38 questions were asked to medical and pharmacy students respectively. Scores were calculated for preparedness, engagement willingness and teaching preferences to enable various comparisons. Exploratory factor analysis was used to explore the questionnaire construct. RESULTS: A total of 479 participants completed the survey- 233 medical students from 7 universities and 246 pharmacy students from 4 universities. Median overall preparedness score indicated that most students felt prepared in at least 14 questions (out of 22 for medical students, and 19 for pharmacy students). Engagement scores for medical and pharmacy students were similar (2 and 3 out of 4). Overall, more than half reported that 'yes, very likely' they received adequate training to ensure the appropriate use of antibiotics in their professional areas (n = 254, 53.5%). Medical and pharmacy students with low preparedness scores expressed a need for more education. Most of both medical and pharmacy students considered the antibiotic situation in Romania 'will get worse' (n = 159, 33.5%). CONCLUSIONS: The study's findings have important implications for the education and training of future Romanian health professionals and highlight the need for further research on optimal and standardized tools to allow for periodic monitoring and evaluation of progress into preparedness, engagement willingness and teaching preferences on antibiotic use.

Clinical and Ecological Impact of an Educational Program to Optimize Antibiotic Treatments in Nursing Homes (PROA-SENIOR): A Cluster, Randomized, Controlled Trial and Interrupted Time-Series Analysis.

BACKGROUND: Antimicrobial stewardship programs (ASPs) are recommended in nursing homes (NHs), although data are limited. We aimed to determine the clinical and ecological impact of an ASP for NHs. METHODS: We performed a cluster, randomized, controlled trial and a before-after study with interrupted time-series analyses in 14 NHs for 30 consecutive months from July 2018 to December 2020 in Andalusia, Spain. Seven facilities implemented an ASP with a bundle of 5 educational measures (general ASP) and 7 added 1-to-1 educational interviews (experimental ASP). The primary outcome was the overall use of antimicrobials, calculated monthly as defined daily doses (DDD) per 1000 resident days (DRD). RESULTS: The total mean antimicrobial consumption decreased by 31.2% (-16.72 DRD; P = .045) with respect to the preintervention period; the overall use of quinolones and amoxicillin-clavulanic acid dropped by 52.2% (P = .001) and 42.5% (P = .006), respectively; and the overall prevalence of multidrug-resistant organisms (MDROs) decreased from 24.7% to 17.4% (P = .012). During the intervention period, 12.5 educational interviews per doctor were performed in the experimental ASP group; no differences were found in the total mean antimicrobial use between groups (-14.62 DRD; P = .25). Two unexpected coronavirus disease 2019 waves affected the centers increasing the overall mean use of antimicrobials by 40% (51.56 DRD; P < .0001). CONCLUSIONS: This study suggests that an ASP for NHs appears to be associated with a decrease in total consumption of antimicrobials and prevalence of MDROs. This trial did not find benefits associated with educational interviews, probably due to the coronavirus disease 2019 pandemic. Clinical Trials Registration. NCT03543605.

The Influence of Rapid Influenza Diagnostic Testing on Clinician Decision-Making for Patients With Acute Respiratory Infection in Urgent Care.

BACKGROUND: The potential benefits of using rapid influenza diagnostic tests (RIDTs) in urgent care facilities for clinical care and prescribing practices are understudied. We compared antiviral and antibiotic prescribing, imaging, and laboratory ordering in clinical encounters with and without RIDT results. METHODS: We compared patients with acute respiratory infection (ARI) symptoms who received an RIDT and patients who did not at 2 urgent care facilities. Primary analysis using 1-to-1 exact matching resulted in 1145 matched pairs to which McNemar 2 × 2 tests were used to assess the association between the likelihood of prescribing, imaging/laboratory ordering, and RIDT use. Secondary analysis compared the same outcomes using logistic regression among the RIDT-tested population between participants who tested negative (RIDT(-)) and positive (RIDT(+)). RESULTS: Primary analysis revealed that compared to the non-RIDT-tested population, RIDT(+) patients were more likely to be prescribed antivirals (OR, 10.23; 95% CI, 5.78-19.72) and less likely to be prescribed antibiotics (OR, 0.15; 95% CI, .08-.27). Comparing RIDT-tested to non-RIDT-tested participants, RIDT use increased antiviral prescribing odds (OR, 3.07; 95% CI, 2.25-4.26) and reduced antibiotic prescribing odds (OR, 0.52; 95% CI, .43-.63). Secondary analysis identified increased odds of prescribing antivirals (OR, 28.21; 95% CI, 18.15-43.86) and decreased odds of prescribing antibiotics (OR, 0.20; 95% CI, .13-.30) for RIDT(+) participants compared with RIDT(-). CONCLUSIONS: Use of RIDTs in patients presenting with ARI symptoms influences clinician diagnostic and treatment decision-making, which could lead to improved patient outcomes, population-level reductions in influenza burden, and a decreased threat of antibiotic resistance.

Do clinical and communication skills scores on credentialing exams predict potentially inappropriate antibiotic prescribing?

BACKGROUND: There is considerable variation among physicians in inappropriate antibiotic prescribing, which is hypothesized to be attributable to diagnostic uncertainty and ineffective communication. The objective of this study was to evaluate whether clinical and communication skills are associated with antibiotic prescribing for upper respiratory infections and sinusitis. METHODS: A cohort study of 2,526 international medical graduates and 48,394 U.S. Medicare patients diagnosed by study physicians with an upper respiratory infection or sinusitis between July 2014 and November 2015 was conducted. Clinical and communication skills were measured by scores achieved on the Clinical Skills Assessment examination administered by the Educational Commission for Foreign Medical Graduates (ECFMG) as a requirement for entry into U.S residency programs. Medicare Part D data were used to determine whether patients were dispensed an antibiotic following an outpatient evaluation and management visit with the study physician. Physician age, sex, specialty and practice region were retrieved from the ECFMG databased and American Medical Association (AMA) Masterfile. Multivariate GEE logistic regression was used to evaluate the association between clinical and communication skills and antibiotic prescribing, adjusting for other physician and patient characteristics. RESULTS: Physicians prescribed an antibiotic in 71.1% of encounters in which a patient was diagnosed with sinusitis, and 50.5% of encounters for upper respiratory infections. Better interpersonal skills scores were associated with a significant reduction in the odds of antibiotic prescribing (OR per score decile 0.93, 95% CI 0.87-0.99), while greater proficiency in clinical skills and English proficiency were not. Female physicians, those practicing internal medicine compared to family medicine, those with citizenship from the US compared to all other countries, and those practicing in southern of the US were also more likely to prescribe potentially unnecessary antibiotics. CONCLUSIONS: Based on this study, physicians with better interpersonal skills are less likely to prescribe antibiotics for acute sinusitis and upper respiratory infections. Future research should examine whether tailored interpersonal skills training to help physicians manage patient expectations for antibiotics could reduce unnecessary antibiotic prescribing.

How Clinicians Decide? Exploring Complexity of Antibiotic Prescribing in Emergency Departments Using Video-Reflexive Ethnography.

Antibiotic overprescribing is a global issue that significantly contributes to increased antimicrobial resistance. Strengthening antimicrobial prescribing practices should be considered a priority. The emergency department (ED) represents a setting where antibiotics are frequently prescribed, but the determinants that influence prescribing choices are complex and multifaceted. We conducted an exploratory qualitative study to investigate the contextual factors that influence antibiotic prescribing choices among clinicians in the ED. The study employed video-reflexive ethnography (VRE) to capture prospective clinical decision-making in situated practice. Data collection involved fieldwork observations, video observations, and delivery of facilitated group reflexive sessions, where clinicians viewed a selection of recorded video snippets relating to antibiotic prescribing. Study was conducted across two EDs within the same health service in Australia. A total of 29 clinical conversations focusing on antibiotic prescribing were recorded. Additionally, 34 clinicians participated in group reflexive sessions. Thematic analysis from the transcribed data yielded four themes: 'importance of clinical judgment', 'usability of prescribing guidelines', 'managing patient expectations', and 'context-dependent disruptions'. Our findings provide insights into the challenges faced by clinicians in navigating complex ED environment, utilising electronic decision-support tools and engaging in discussions about patient treatments with senior clinicians. The findings also indicate that VRE is useful in visualising full complexity of the ED setting, and in initiating meaningful discussions among clinical teams. Integrating the use of VRE in everyday clinical settings can potentially facilitate the implementation of pragmatic solutions for delivering effective antibiotic stewardship practices.

A Narrative Review of Recent Antibiotic Prescribing Practices in Ambulatory Care in Tanzania: Findings and Implications.

Background and objectives: There are concerns with the current prescribing practices of antibiotics in ambulatory care in Tanzania, including both the public and private sectors. These concerns need to be addressed as part of the national action plan (NAP) of Tanzania to reduce rising antimicrobial resistance (AMR) rates. Issues and concerns include high rates of prescribing of antibiotics for essentially self-limiting conditions. Consequently, there is a need to address this. As a result, the aims of this narrative review were to comprehensively summarize antibiotic utilization patterns particularly in ambulatory care and their rationale in Tanzania and to suggest ways forward to improve future prescribing practices. Materials and Methods: We undertook a narrative review of recently published studies and subsequently documented potential activities to improve future prescribing practices. Potential activities included instigating quality indicators and antimicrobial stewardship programs (ASPs). Results: Published studies have shown that antibiotics are being excessively prescribed in ambulatory care in Tanzania, in up to 95% to 96.3% of presenting cases depending on the sector. This is despite concerns with their appropriateness. High rates of antibiotic prescribing are not helped by variable adherence to current treatment guidelines. There have also been concerns with extensive prescribing of 'Watch' antibiotics in the private sector. Overall, the majority of antibiotics prescribed across the sectors, albeit inappropriately, were typically from the 'Access' group of antibiotics in the AWaRe (Access/Watch/Reserve) classification rather than 'Watch' antibiotics to limit AMR. The inappropriate prescribing of antibiotics in ambulatory care is linked to current knowledge regarding antibiotics, AMR, and ASPs among both prescribers and patients. Recommended activities for the future include improved education for all groups, the instigation of updated quality indicators, and the regular monitoring of prescribing practices against agreed-upon guidelines and indicators. Education for healthcare professionals on ASPs should start at undergraduate level and continue post qualification. Community advocacy on the rational use of antibiotics should also include social media activities to dispel misinformation. Conclusion: The quality of current prescribing practices of antibiotics in ambulatory care is sub-optimal in Tanzania. This needs to be urgently addressed.

Improving Outpatient Antibiotic Prescribing for Respiratory Tract Infections in Primary Care: A Stepped-Wedge Cluster Randomized Trial.

BACKGROUND: Inappropriate antibiotic prescribing is common in primary care (PC), particularly for respiratory tract diagnoses (RTDs). However, the optimal approach for improving prescribing remains unknown. METHODS: We conducted a stepped-wedge study in PC practices within a health system to assess the impact of a provider-targeted intervention on antibiotic prescribing for RTDs. RTDs were grouped into tiers based on appropriateness of antibiotic prescribing: tier 1 (almost always indicated), tier 2 (may be indicated), and tier 3 (rarely indicated). Providers received education on appropriate RTD prescribing followed by monthly peer comparison feedback on antibiotic prescribing for (1) all tiers and (2) tier 3 RTDs. A χ 2 test was used to compare the proportion of visits with antibiotic prescriptions before and during the intervention. Mixed-effects multivariable logistic regression analysis was performed to assess the association between the intervention and antibiotic prescribing. RESULTS: Across 30 PC practices and 185 755 total visits, overall antibiotic prescribing was reduced with the intervention, from 35.2% to 23.0% of visits (P < .001). In multivariable analysis, the intervention was associated with a reduced odds of antibiotic prescription for tiers 2 (odds ratio [OR] 0.57; 95% confidence interval [CI] .52-.62) and 3 (OR 0.57; 95% CI .53-.61) but not for tier 1 (OR 0.98; 95% CI .83-1.16). CONCLUSIONS: A provider-focused intervention reduced overall antibiotic prescribing for RTDs without affecting prescribing for infections that likely require antibiotics. Future research should examine the sustainability of such interventions, potential unintended adverse effects on patient health or satisfaction, and provider perceptions and acceptability.

Current Status of Outpatient Oral Antimicrobial Prescription and the Influence of Antimicrobial Stewardship for Inpatients: A Repeated Cross-Sectional Study at a Japanese Community Hospital.

This study aimed to clarify the details of outpatient oral antimicrobial use (AMU) at a Japanese community hospital and investigate the influence of the current inpatient-based antimicrobial stewardship (AS) on outpatients. A repeated cross-sectional study was conducted in Komaki City Hospital. Data on patients, physicians, and oral antibiotics were collected in October 2013, 2016, and 2019, and appropriateness of treatment and surgical antimicrobial prophylaxis (SAP) was evaluated. The percentage of patients receiving oral antibiotics increased significantly from 4.7% in 2013 (345/7338) to 5.9% in 2019 (365/6146), and the overall number of antimicrobial prescriptions per 1000 outpatients increased from 51.8 in 2013 to 68.0 in 2019. Prescriptions for third-generation cephalosporins per 1000 outpatients decreased (from 21.4 to 6.3), whereas the number of prescriptions for penicillin (from 3.8 to 15.3), fluoroquinolones (from 7.0 to 13.2), and co-trimoxazole (from 5.0 to 15.8) increased from 2013 to 2019. The appropriate AMU for overall infections significantly increased (from 68.4% in 2013 to 83.7% in 2019). The choice and duration of AMU significantly improved for SAP. However, even in 2019, only 29.3% of patients received antibiotics before surgery. The improved selection of antibiotics on outpatient prescription may be due to the influence of AS-which is focused on inpatients-while prescriptions for fluoroquinolones and prophylactics also increased. The challenges of antimicrobial administration after surgeries were also highlighted.

Throat infections and use of streptococcal antigen test and antibiotic treatment in general practice; a web-based survey.

OBJECTIVE: The aim of this study was to investigate the use of streptococcal antigen tests and antibiotic prescription in general practice in Norway in relation to the national guidelines for sore throat. DESIGN: This study was based on a web-based survey. SETTING: Norwegian general practice. SUBJECTS: 4700 members of the Norwegian College of General Practice received the survey by E-mail. MAIN OUTCOME MEASURES: General practitioner (GP) adherence to national guidelines. RESULTS: In total, 807 GPs responded and were included in the study. According to the guidelines, 20% and 30% of the GPs would perform unnecessary streptococcal antigen testing when presented with mild and severe infections respectively, while 52% would not perform the test at moderate infection. Phenoxymethylpenicillin was recommended by 95% of the GPs. CONCLUSION: In this survey of self-selected GPs, we identified some non-adherence to National guidelines for streptococcal antigen testing and antibiotic prescribing. However, when antibiotic treatment was offered, the correct antibiotics were prescribed.Key pointsNorwegian guidelines for diagnosis and treatment of throat infections include the use of Centor criteria as a clinical tool to limit the unnecessary use of antibiotics. In this web-based survey, we investigated the use of streptococcal antigen tests and antibiotic prescription in general practice in relation to the national guidelines.•Streptococcal antigen tests were not always performed according to Norwegian guidelines, causing inappropriate antibiotic prescribing.•National guidelines were followed in the choice of antibiotics for sore throat.

Applying the Kirkpatrick model to evaluate dental students' experience of learning about antibiotics use and resistance.

INTRODUCTION: "Antibiotic resistance" is of main concern in global health and that it could hinder the achievement of sustainable development goals. One of the reported contributing factors is the irrational prescribing behaviour of healthcare professionals including dentists. Efforts to design and evaluate effective educational programmes for undergraduate dental students about appropriate prescribing behaviour during their early educational years could mitigate the risk of antibiotic resistance. MATERIALS AND METHODS: A total of 322 students participated in the study. Their knowledge of antibiotics and antibiotic resistance was assessed. Students received a specially designed, interactive educational programme. The success of the programme was assessed after the educational sessions and 2 years later using Kirkpatrick's four-level evaluation model. RESULTS: This study is the first study to use Kirkpatrick model to evaluate an educational programme for dental students. The results of the first level of evaluation showed an overall satisfaction score of 82.1%. The second level revealed an increase in the percentage of correct answers after the educational sessions from 68.3% to 80%, and significant agreement with responsible antibiotics usage (p-value = .020, Effect size = 0.121). The third level showed that the percentage of correct answers 2 years later was 87.5%. The fourth level confirmed the success of the programme as 88.9% of participants reported using the knowledge gained from the programme when prescribing antibiotics. CONCLUSIONS: Our study emphasises the success of the used educational programme and highlights the need for educational interventions in the under graduate dental curriculum.

Childhood Respiratory Outpatient Visits Correlate With Socioeconomic Status and Drive Geographic Patterns in Antibiotic Prescribing.

BACKGROUND: Reducing geographic disparities in antibiotic prescribing is a central public health priority to combat antibiotic resistance, but drivers of this variation have been unclear. METHODS: We measured how variation in outpatient visit rates (observed disease) and antibiotic prescribing rates per visit (prescribing practices) contributed to geographic variation in per capita antibiotic prescribing in Massachusetts residents younger than 65 years between 2011 and 2015. RESULTS: Of the difference in per capita antibiotic prescribing between high- and low-prescribing census tracts in Massachusetts, 45.2% was attributable to variation in outpatient visit rates, while 25.8% was explained by prescribing practices. Outpatient visits for sinusitis, pharyngitis, and suppurative otitis media accounted for 30.3% of the gap in prescribing, with most of the variation in visit rates concentrated in children younger than 10 years. Outpatient visits for these conditions were less frequent in census tracts with high social deprivation index. CONCLUSIONS: Interventions aimed at reducing geographic disparities in antibiotic prescribing should target the drivers of outpatient visits for respiratory illness and should account for possible underutilization of health services in areas with the lowest antibiotic consumption. Our findings challenge the conventional wisdom that prescribing practices are the main driver of geographic disparities in antibiotic use.
