Implementation of treatment guidelines to support judicious use of antibiotic therapy

Knowledge, Attitude, and Behavior about Antimicrobial Use and Resistance among Medical, Nursing and Pharmacy Students in Jordan: A Cross Sectional Study

The present study aimed to survey medical, nursing and pharmacy students' knowledge, attitude and practice regarding antimicrobial use and resistance. Additionally, the study assessed the teaching and assessment activities received regarding antibiotic use. A cross sectional online survey was distributed to undergraduate students currently in clinical studies in their degree program. A total of 716 medicine, nursing and pharmacy undergraduate students were included. Respondents scored more than 76% on knowledge on effective use, unnecessary use and associated side effects of antibiotics, and 65.2% regarding knowledge on the spread of antibiotic resistance. Some participants (21.0%) agreed or strongly agreed that there has been good promotion of prudent antimicrobial use. Students were aware (13.1%), unaware (29.1%), or unsure (57.8%) that there is a national action plan relating to antimicrobial resistance. A total of 62.8% of the respondents strongly agreed or agreed that they have a key role in helping control antibiotic resistance. Participants reported that they require more information about resistance to antibiotics (53.9%), medical conditions for which antibiotics are used (51.7%) and how to use antibiotics (51.0%). Discussion of clinical cases and vignettes and small group teaching were reported as very useful or useful teaching strategies (79.9% and 74.2%, respectively). The findings from this study determined the current situation in relation to education on prudent antimicrobial use for undergraduates and highlighted areas for informing better curriculum design.

Studying Factors Affecting Success of Antimicrobial Resistance Interventions through the Lens of Experience: A Thematic Analysis

Antimicrobial resistance (AMR) affects the environment, and animal and human health. Institutions worldwide have applied various measures, some of which have reduced antimicrobial use and AMR. However, little is known about factors influencing the success of AMR interventions. To address this gap, we engaged health professionals, designers, and implementers of AMR interventions in an exploratory study to learn about their experience and factors that challenged or facilitated interventions and the context in which interventions were implemented. Based on participant input, our thematic analysis identified behaviour; institutional governance and management; and sharing and enhancing information as key factors influencing success. Important sub-themes included: correct behaviour reinforcement, financial resources, training, assessment, and awareness of AMR. Overall, interventions were located in high-income countries, the human sector, and were publicly funded and implemented. In these contexts, behaviour patterns strongly influenced success, yet are often underrated or overlooked when designing AMR interventions. Improving our understanding of what contributes to successful interventions would allow for better designs of policies that are tailored to specific contexts. Exploratory approaches can provide encouraging results in complex challenges, as made evident in our study. Remaining challenges include more engagement in this type of study by professionals and characterisation of themes that influence intervention outcomes by context.

A roadmap for the development and evaluation of the eHealthResp online course

Background

Inappropriate antibiotic use constitutes one of the most concerning public health issues, being one of the main causes of antibiotic resistance. Hence, to tackle this issue, it is important to encourage the development of educational interventions for health practitioners, namely by using digital health tools. This study focuses on the description of the development and validation process of the eHealthResp online course, a web platform directed to physicians and pharmacists, with the overall goal of improving antibiotic use for respiratory tract infections, along with the assessment of its usability.

Methods

The eHealthResp platform and the courses, developed with a user-centered design and based on Wordpress and MySQL, were based on a previously developed online course. A questionnaire to assess the usability was distributed among physicians (n = 6) and pharmacists (n = 6). Based on the obtained results, statistical analyses were conducted to calculate the usability score and appraise the design of the online course, as well as to compare the overall scores attributed by both groups. Further qualitative comments provided by the participants have also been analyzed.

Results

The eHealthResp contains two online courses directed to physicians and pharmacists aiming to aid in the management of respiratory tract infections. The average usability score of the eHealthResp online courses for physicians and pharmacists was of 78.33 (±11.57, 95%CI), and 83.75 (±15.90, 95%CI), respectively. Qualitative feedback emphasized the usefulness of the course, including overall positive reviews regarding user-friendliness and consistency.

Conclusions

This study led us to conclude that the eHealthResp online course is not recognized as a complex web platform, as both qualitative and quantitative feedback obtained were globally positive.

Exploring Information Available to and Used by Physicians on Antibiotic Use and Antibiotic Resistance in Jordan

Evidence based information sources for physicians are needed for informed antibiotic prescribing practices. The aim of this study was to explore physicians' preferred sources of information and evaluate physicians' awareness of available information and initiatives on prudent antibiotic prescribing in Jordan. A cross-sectional study was conducted utilizing an online questionnaire and included physicians (n = 409) from all sectors and specialties in Jordan. Published guidelines (31.8%), the workplace (25.7%), colleagues or peers (20.0%), group or conference training (18.3%), and the medical professional body (18.1%) were the main sources of information about avoiding unnecessary antibiotic prescribing, with the influence of these sources on changing prescribers' views being 34.7%, 17.1%, 11%, 13.4%, and 7.6%, respectively. One-third of physicians (33.7%) reported no knowledge of any initiatives on antibiotic awareness and resistance. Regarding awareness of national action plans on antimicrobial resistance, 10.5%, 34%, and 55.5% of physicians were aware, unaware, and unsure of the presence of any national action plans, respectively. Physicians showed interest in receiving more information on resistance to antibiotics (58.9%), how to use antibiotics (42.2%), medical conditions for which antibiotics are used (41.3%), prescribing of antibiotics (35.2%), and links between the health of humans, animals, and the environment (19.8%). The findings can inform interventions needed to design effective antimicrobial stewardship, enabling physicians to prescribe antibiotics appropriately.

Validation of the eHealthResp online course for pharmacists and physicians: A Delphi method approach

FRAMEWORK

The inappropriate use of antibiotics for respiratory tract infections is dispersed worldwide, thus being a strong contributor to antibiotic resistances. As the use of educational interventions among health practitioners is shown to have an impact on judicious antibiotic use, an online course (eHealthResp) has been developed, especially targeted to pharmacists and physicians. Thus, the main goal of this study is to validate the contents of the online course eHealthResp.

METHODS

This two-round Delphi study involved the recruitment of a multidisciplinary panel (n = 19), to which the questionnaires of the first round were sent. After the first round, a report summing up the results has been forwarded to the panel, along with a new, reformulated version of the questionnaire.

RESULTS

After the two rounds of the Delphi process, consensus was evaluated. Six clinical cases and fifty-one treatments obtained minor consensus [60-75%] or full consensus (≥75%). The question on antibiotic practice has obtained a consensus >90% on both rounds.

CONCLUSIONS

The validation of the contents based on experts' consensus has been an essential approach to improve eHealthResp's online course, as valuable feedback has been provided by the panel on both rounds.

Comparison of antimicrobial prescription patterns in calves in Switzerland before and after the launch of online guidelines for prudent antimicrobial use

BACKGROUND

The increasing threat of bacterial resistance promotes the need for antibiotic stewardship programs to foster responsible antimicrobial use. Therefore, guidelines for prudent use supported by an online stewardship tool (AntibioticScout.ch) were introduced in Switzerland in December 2016. They recommend (with decreasing preference) a first, second or third line antimicrobial for treatment. The objective of this study was to evaluate antimicrobial prescriptions for Swiss calves before (2016) and after (2018) the launch of these guidelines. Cases of calves with pneumonia, diarrhea and otitis from a university hospital and eight private practices in Switzerland were included. Data on anamnesis, clinical findings, diagnostic work-up and treatment were collected. Type and percentages [95% confidence interval] of antimicrobial prescriptions were compared between 2016 and 2018.

RESULTS

Of the total number of calves, 88.2% [85.4-90.6] in 2016 (n = 625) and 88.4% [85.7-90.7] in 2018 (n = 655) were treated with antibiotics. The use of highest priority critically important antimicrobials (HPCIAs) decreased from 52.7% [48.6-56.9] in 2016 to 38.0% [34.2-41.9] in 2018; this decrease was found at the university hospital and in private practice and in cases with pneumonia and diarrhea. Particularly the use of fluoroquinolones decreased (2016: 43.1% [39.2-47.2]; 2018: 31.1% [27.6-34.8]). Overall, the number of first line treatments increased from 12.8% [10.4-15.6] in 2016 to 20.2% [17.3-23.4] in 2018. In cases of pneumonia, first line treatments increased (2016: 15.3% [11.6-19.9]; 2018: 26.5% [21.8-31.9]) and third line treatments decreased (2016: 43.5% [38.0-49.3]; 2018: 27.9% [23.1-33.3]); this was seen at the university hospital, whereas in private practice only a decrease of third line treatments was observed. In cases of diarrhea, more second line at the expense of unlisted antimicrobials were prescribed at the university hospital in 2018. Antimicrobial treatment of calves with otitis did not change from 2016 to 2018.

CONCLUSIONS

After the introduction of AntibioticScout.ch, more prudent use was observed in the treatment of calves with pneumonia and diarrhea as less HPCIAs, particularly fluoroquinolones, and more first line antimicrobials were prescribed. However, the overall frequency of antimicrobial treatment did not change and the use of HPCIAs was still common in 2018, especially in private practices. Therefore, further antimicrobial stewardship activities are necessary.

Antimicrobial prescriptions in cats in Switzerland before and after the introduction of an online antimicrobial stewardship tool

BACKGROUND

Antimicrobial stewardship activities are essential to improve prudent antimicrobial use. The aim of the present study was to evaluate changes in antimicrobial prescriptions in cats after the introduction of prudent use guidelines promoted by an online antimicrobial stewardship tool (AntibioticScout.ch) in Switzerland. Data from 792 cats presented to two university hospitals and 14 private practices in 2018 were included and compared to 776 cases from 2016. Cats were diagnosed with acute upper respiratory tract disease (aURTD), feline lower urinary tract disease (FLUTD) and abscesses. Clinical history, diagnostic work-up and antimicrobial prescriptions (class, dosage, duration) were assessed. Type and proportions [95% confidence intervals] of antimicrobial prescriptions were compared between the two evaluation periods and a mixed effects logistic regression model was applied to evaluate compliance with Swiss prudent use guidelines.

RESULTS

From 2016 to 2018, the proportion of antimicrobial prescription in all included cases decreased from 75.0% [71.8-78.0] to 66.7% [63.3-69.9]; this decrease was most pronounced for treatments at university hospitals (67.1% [59.5-74.0] to 49.3% [40.9-57.8]) and for cats with FLUTD (60.1% [54.6-65.4] to 48.8% [43.2-54.4]). Use of 3rd generation cephalosporins in private practices declined from 30.7% [26.5-35.1] to 22.1% [18.4-26.2], while overall use of non-potentiated aminopenicillins increased from 19.6% [16.4-23.0] to 27.8% [24.1-31.9]. In cases where antimicrobial therapy was indicated, compliance with guidelines did not increase (33.3% [26.6-40.6] to 33.5% [27.2-40.2]), neither at universities nor in private practices. On the other hand, antimicrobial treatment was more often withheld in cases with no indication for antimicrobial therapy (35.6% [30.1-41.4] to 54.0% [47.6-60.4]); this was found for private practices (26.7% [20.8-33.4] to 46.0% [38.4-53.7]) and for aURTD cases (35.0% [26.5-44.2] to 55.4% [44.7-65.8]).

CONCLUSIONS

Overall proportions of antimicrobial prescription, unjustified antimicrobial therapy and, in private practices, use of 3rd generation cephalosporins decreased from 2016 to 2018 for the investigated feline diseases. However, overall compliance with Swiss prudent use guidelines was still low, implying that further efforts are required to foster prudent antimicrobial use in cats.

Evidence-Based Strategies in Using Persuasive Interventions to Optimize Antimicrobial Use in Healthcare: a Narrative Review

A rise in antimicrobial resistance, seen especially since 2000, is in part caused by indiscriminate antimicrobial use. Varied types of persuasive interventions aimed to optimize antimicrobial use have been tried with varying success. Our review seeks to identify and assess factors associated with the successful implementation of persuasive interventions. We searched five databases (MEDLINE, EMBASE, The Cochrane Library, PsycINFO, and ERIC) to identify critical studies published between 2000 and December 2018 of interventions employing audit and feedback, education through meetings, academic detailing, reminders, and patient, family, or public education. Outcome measures of interest were any means to measure antimicrobial use. We included 26 articles in our analysis. Seventeen examined multimodal interventions and the most common was audit and feedback and meeting (four studies). Nine examined single interventions and the most common was audit and feedback (five studies). Our findings inform four evidence-based strategies to enable healthcare administrators, clinicians, and researchers to make informed choices when planning and designing an antimicrobial stewardship program: (1) implement a combination of persuasive interventions from both groups: audit and feedback, academic detailing, or patient, family, or provider education; and meeting or reminders, (2) design interventions that last one year or longer; post-intervention, assess the intervention's long-term effects for at least another one year, (3) conduct quality improvement projects examining persuasive interventions if the prescribing database provides adequate diagnosis information, and most importantly, (4) make patient, family, or provider education an integral component of multimodal intervention.

Usage patterns of carbapenem antimicrobials in dogs and cats at a veterinary tertiary care hospital

BACKGROUND

Carbapenems are a class of antimicrobials reserved for resistant infections or systemically ill people, yet the extent and context in which they are prescribed in the small animals is understudied.

HYPOTHESIS/OBJECTIVE

To describe cases in dogs and cats treated with carbapenems to establish baseline data regarding the types of infections, outcomes, and resistance profiles of target infections. We hypothesize that prescribing practices for carbapenems at a veterinary tertiary care hospital would not comply with the recommended use guidelines in human medicine.

METHODS

Retrospective study of veterinary medical records from all dogs and cats prescribed carbapenems between May 1, 2016, and April 30, 2017.

RESULTS

A total of 81 infections (71 in dogs and 10 in cats) representing 68 animals (58 dogs and 10 cats) involving carbapenem use were identified. Cultures were performed in 65/81 (80%) infections, and antimicrobial use was de-escalated or discontinued in 10/81 (12%) infections. The average duration of treatment was 27.5 days and ranged from 1 to 196 days. Resistance to more than 3 antimicrobial classes was present in 57/115 (50%) isolates. Resistance to carbapenems was found in 2/64 (3%) of the bacterial isolates with reported carbapenem susceptibility.

CONCLUSIONS AND CLINICAL IMPORTANCE

The majority of carbapenem use at a veterinary tertiary care hospital was prescribed in conjunction with culture and sensitivity determination, with de-escalation performed in a minority of cases, and treatment durations longer than typically recommended in human medicine.

International Society for Companion Animal Infectious Diseases (ISCAID) guidelines for the diagnosis and management of bacterial urinary tract infections in dogs and cats

Urinary tract disease is a common clinical presentation in dogs and cats, and a common reason for antimicrobial prescription. This document is a revision and expansion on the 2011 Antimicrobial Use Guidelines for Treatment of Urinary Tract Disease in Dogs and Cats, providing recommendations for diagnosis and management of sporadic bacterial cystitis, recurrent bacterial cystitis, pyelonephritis, bacterial prostatitis, and subclinical bacteriuria. Issues pertaining to urinary catheters, medical dissolution of uroliths and prophylaxis for urological procedures are also addressed.

Interventions to improve antimicrobial prescribing of doctors in training (IMPACT): a realist review

Background

Interventions to improve the antimicrobial prescribing practices of doctors have been implemented widely to curtail the emergence and spread of antimicrobial resistance, but have been met with varying levels of success.

Objectives

This study aimed to generate an in-depth understanding of how antimicrobial prescribing interventions ‘work’ (or do not work) for doctors in training by taking into account the wider context in which prescribing decisions are enacted.

Design

The review followed a realist approach to evidence synthesis, which uses an interpretive, theory-driven analysis of qualitative, quantitative and mixed-methods data from relevant studies.

Setting

Primary and secondary care.

Participants

Not applicable.

Interventions

Studies related to antimicrobial prescribing for doctors in training.

Main outcome measures

Not applicable.

Data sources

EMBASE (via Ovid), MEDLINE (via Ovid), MEDLINE In-Process & Other Non-Indexed Citations (via Ovid), PsycINFO (via Ovid), Web of Science core collection limited to Science Citation Index Expanded (SCIE) and Conference Proceedings Citation Index – Science (CPCI-S) (via Thomson Reuters), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, the Health Technology Assessment (HTA) database (all via The Cochrane Library), Applied Social Sciences Index and Abstracts (ASSIA) (via ProQuest), Google Scholar (Google Inc., Mountain View, CA, USA) and expert recommendations.

Review methods

Clearly bounded searches of electronic databases were supplemented by citation tracking and grey literature. Following quality standards for realist reviews, the retrieved articles were systematically screened and iteratively analysed to develop theoretically driven explanations. A programme theory was produced with input from a stakeholder group consisting of practitioners and patient representatives.

Results

A total of 131 articles were included. The overarching programme theory developed from the analysis of these articles explains how and why doctors in training decide to passively comply with or actively follow (1) seniors’ prescribing habits, (2) the way seniors take into account prescribing aids and seek the views of other health professionals and (3) the way seniors negotiate patient expectations. The programme theory also explains what drives willingness or reluctance to ask questions about antimicrobial prescribing or to challenge the decisions made by seniors. The review outlines how these outcomes result from complex inter-relationships between the contexts of practice doctors in training are embedded in (hierarchical relationships, powerful prescribing norms, unclear roles and responsibilities, implicit expectations about knowledge levels and application in practice) and the mechanisms triggered in these contexts (fear of criticism and individual responsibility, reputation management, position in the clinical team and appearing competent). Drawing on these findings, we set out explicit recommendations for optimal tailoring, design and implementation of antimicrobial prescribing interventions targeted at doctors in training.

Limitations

Most articles included in the review discussed hospital-based, rather than primary, care. In cases when few data were available to fully capture all the nuances between context, mechanisms and outcomes, we have been explicit about the strength of our arguments.

Conclusions

This review contributes to our understanding of how antimicrobial prescribing interventions for doctors in training can be better embedded in the hierarchical and interprofessional dynamics of different health-care settings.

Future work

More work is required to understand how interprofessional support for doctors in training can contribute to appropriate prescribing in the context of hierarchical dynamics.

Pharmacists Views and Practices in Regard to Sales of Antibiotics Without a Prescription in Madinah, Saudi Arabia

OBJECTIVE

The aim of this study was to investigate pharmacists views and practices in Madinah, Saudi Arabia, through conducting direct interviews including direct questions and hypothetical scenarios.

METHODS

A purposeful sample of 150 community pharmacists of different ethnic and educational backgrounds were approached to participate in the study. Semistructured interviews including general questions and 5 hypothetical scenarios were used for the investigation. Complete transcripts of the interviews were prepared. All transcripts were coded and categorized into main themes using a computer software.

RESULTS

Fifty-four pharmacists agreed to participate (response rate, 36%). Sale of antibiotics without prescription is commonly practiced in Saudi Arabia. Lack of legislation enforcement has exacerbated this practice. Economic hardship, patient's age, emotional factors, and pharmacists' self confidence in diagnosing and prescribing medications in general and antibiotics in particular were the themes included in the interviews and influenced pharmacists' decision to sell antibiotics without a prescription.Many pharmacists did not see the practice as a problem and felt capable of continuing to dispense antibiotics without a prescription. Pharmacists who saw the practice as a problem sees legislation enforcement to be the solution of the problem.

CONCLUSIONS

Pharmacist views and practices are alarming. The results of this study show that this practice will continue to spread unless strict enforcement is put in place, Lack of clear understanding of the limitations of pharmacist's scope of practice. Results of these studies can be extrapolated to other countries in the region and other countries of the similar social and professional development status.

Factors Associated With the Prophylactic Prescription of a Bowel Regimen to Prevent Opioid-Induced Constipation

OBJECTIVE

Identify factors associated with the prophylactic prescription of a bowel regimen with an inpatient opioid prescription.

METHODS

This was a retrospective cohort study from June 1, 2013, to October 31, 2014 of pediatric inpatients prescribed an oral or intravenous opioid on the general medical/surgical floors. We identified patients with or without a prophylactic prescription of a bowel regimen. We obtained patient demographics, prescriber training level and service and used multivariate logistic regression to analyze the factors associated with prophylactic bowel regimen and opioid prescription.

RESULTS

Of the 6682 encounters that met study criteria, only 966 (14.5%) encounters had prophylactic prescriptions. Patient factors associated with prophylactic prescription include increasing age (per year; odds ratio [OR] = 1.06, 95% confidence interval [CI] 1.05-1.07) and sickle cell diagnosis (OR = 3.19, 95% CI 2.08-4.91). Medication factors associated with prophylactic prescription include a scheduled opioid prescription (OR = 1.75, 95% CI 1.46-2.1) and a prescription for oxycodone (OR = 3.59, 95% CI 2.57-5.00) or morphine (OR = 1.84, 95% CI 1.39-2.44), compared with acetaminophen-hydrocodone. Compared with medical providers, surgeons were less likely (OR = 0.43, 95% CI 0.35-0.53) and pain service providers were more likely to prescribe a prophylactic bowel regimen (OR = 4.12, 95% CI 3.13-5.43).

CONCLUSIONS

More than 85% of inpatient opioid prescriptions did not receive a prophylactic bowel regimen. Future research should examine factors (eg, clinical decision support tools) to increase prophylactic prescription of bowel regimens with opioids for populations found to have lower rates.

Educational interventions to improve prescription and dispensing of antibiotics: a systematic review

Background

Excessive and inappropriate antibiotic use contributes to growing antibiotic resistance, an important public-health problem. Strategies must be developed to improve antibiotic-prescribing. Our purpose is to review of educational programs aimed at improving antibiotic-prescribing by physicians and/or antibiotic-dispensing by pharmacists, in both primary-care and hospital settings.

Methods

We conducted a critical systematic search and review of the relevant literature on educational programs aimed at improving antibiotic prescribing and dispensing practice in primary-care and hospital settings, published in January 2001 through December 2011.

Results

We identified 78 studies for analysis, 47 in primary-care and 31 in hospital settings. The studies differed widely in design but mostly reported positive results. Outcomes measured in the reviewed studies were adherence to guidelines, total of antibiotics prescribed, or both, attitudes and behavior related to antibiotic prescribing and quality of pharmacy practice related to antibiotics. Twenty-nine studies (62%) in primary care and twenty-four (78%) in hospital setting reported positive results for all measured outcomes; fourteen studies (30%) in primary care and six (20%) in hospital setting reported positive results for some outcomes and results that were not statistically influenced by the intervention for others; only four studies in primary care and one study in hospital setting failed to report significant post-intervention improvements for all outcomes. Improvement in adherence to guidelines and decrease of total of antibiotics prescribed, after educational interventions, were observed, respectively, in 46% and 41% of all the reviewed studies. Changes in behaviour related to antibiotic-prescribing and improvement in quality of pharmacy practice was observed, respectively, in four studies and one study respectively.

Conclusion

The results show that antibiotic use could be improved by educational interventions, being mostly used multifaceted interventions.

Implementation of a computerized decision support system to improve the appropriateness of antibiotic therapy using local microbiologic data

A prospective quasi-experimental study was undertaken in 218 patients with suspicion of nosocomial infection hospitalized in a polyvalent ICU where a new electronic device (GERB) has been designed for antibiotic prescriptions. Two GERB-based applications were developed to provide local resistance maps (LRMs) and preliminary microbiological reports with therapeutic recommendation (PMRTRs). Both applications used the data in the Laboratory Information System of the Microbiology Department to report on the optimal empiric therapeutic option, based on the most likely susceptibility profile of the microorganisms potentially responsible for infection in patients and taking into account the local epidemiology of the hospital department/unit. LRMs were used for antibiotic prescription in 20.2% of the patients and PMRTRs in 78.2%, and active antibiotics against the finally identified bacteria were prescribed in 80.0% of the former group and 82.4% of the latter. When neither LMRs nor PMRTRs were considered for empiric treatment prescription, only around 40% of the antibiotics prescribed were active. Hence, the percentage appropriateness of the empiric antibiotic treatments was significantly higher when LRM or PMRTR guidelines were followed rather than other criteria. LRMs and PMRTRs applications are dynamic, highly accessible, and readily interpreted instruments that contribute to the appropriateness of empiric antibiotic treatments.

A multicenter point-prevalence survey of antibiotic use in 13 Chinese hospitals

BACKGROUND

The use of antibiotics is considered a major determinant of the development of resistance in organisms. This study assessed current patterns of antibiotic prescription and provides background for quality improvement in general hospitals in Hubei, China.

METHODS

A point-prevalence study was performed in November 2008. All inpatients on the day of the survey were included in the analysis.

RESULTS

On the day of the study, 6904 patients (56%) were receiving antibiotic therapy; the highest rate occurred in the ICU (90%), and the lowest occurred in the medical wards (39%). The most commonly used antibiotics were β-lactam antibiotics, including cephalosporins (40%) and piperacillin (19%), followed by fluoroquinolones (14%).

CONCLUSIONS

Our data indicated a high rate of antibiotic use in Chinese hospitals. These findings suggest important areas for intervention and the implementation of antibiotic stewardship policies in Chinese hospitals. A multi-faceted strategy should be implemented at the national level in China and should include education, regulation, and greater financial support from the government.

Guidelines for the diagnosis and antimicrobial therapy of canine superficial bacterial folliculitis (Antimicrobial Guidelines Working Group of the International Society for Companion Animal Infectious Diseases)

BACKGROUND

Superficial bacterial folliculitis (SBF) is usually caused by Staphylococcus pseudintermedius and routinely treated with systemic antimicrobial agents. Infection is a consequence of reduced immunity associated with alterations of the skin barrier and underlying diseases that may be difficult to diagnose and resolve; thus, SBF is frequently recurrent and repeated treatment is necessary. The emergence of multiresistant bacteria, particularly meticillin-resistant S. pseudintermedius (MRSP), has focused attention on the need for optimal management of SBF.

OBJECTIVES

Provision of an internationally available resource guiding practitioners in the diagnosis, treatment and prevention of SBF.

DEVELOPMENT OF THE GUIDELINES

The guidelines were developed by the Antimicrobial Guidelines Working Group of the International Society for Companion Animal Infectious Diseases, with consultation and advice from diplomates of the American and European Colleges of Veterinary Dermatology. They describe optimal methods for the diagnosis and management of SBF, including isolation of the causative organism, antimicrobial susceptibility testing, selection of antimicrobial drugs, therapeutic protocols and advice on infection control. Guidance is given for topical and systemic modalities, including approaches suitable for MRSP. Systemic drugs are classified in three tiers. Tier one drugs are used when diagnosis is clear cut and risk factors for antimicrobial drug resistance are not present. Otherwise, tier two drugs are used and antimicrobial susceptibility tests are mandatory. Tier three includes drugs reserved for highly resistant infections; their use is strongly discouraged and, when necessary, they should be used in consultation with specialists.

CONCLUSIONS AND CLINICAL IMPORTANCE

Optimal management of SBF will improve antimicrobial use and reduce selection of MRSP and other multidrug-resistant bacteria affecting animal and human health.

[Carbapenem antibiotics in hospitalised paediatric patients. Adherence to a therapeutic protocol]

OBJECTIVE

To describe the use of carbapenems in children hospitalised outside intensive care and onco-haematology units, and assess adherence to a therapeutic protocol.

PATIENTS AND METHODS

A retrospective observational study was conducted on the use of carbapenems between January 2009 and December 2010. The study included children with a community-acquired infectious disease or a health care-associated infectious disease, and who were admitted to paediatric areas of the Vall d'Hebron University Hospital (Barcelona, Spain), other than intensive care, neonatology and onco-haematology units. Clinical data were collected and antibiotic consumption data were provided by the Pharmacy Department.

RESULTS

A total of 51 episodes fulfilled the inclusion criteria. Carbapenem as initial empirical treatment was indicated in 31.4%, and applied as rescue therapy in the remainder. The instructions of the protocol were adhered to in 70.6% of the empirical and 87.5% of the targeted prescriptions (77.6% overall). A better match was found for empirical carbapenem in patients with a previous admission or underlying condition. Factors such as diagnosis, age or antibiotic use prior to admission did not affect the empirical indication of carbapenem.

CONCLUSIONS

The establishment of a treatment protocol with carbapenem indications in our centre since 2007 has yielded significantly better results on the appropriateness of the prescription than those obtained in other studies.

Impact of inappropriate empiric antimicrobial therapy on mortality of septic patients with bacteremia: a retrospective study

Background. Inappropriate empiric antimicrobials could be a major cause of unfavorable mortality rates in co-morbid patients. This study aimed to assess the prevalence and impact of first-dose and 24-hour inappropriate antimicrobials on mortality rates of bacteremic septic patients. Methods. A retrospective cohort study was employed. Case record forms of patients diagnosed as sepsis, severe sepsis, or septic shock with positive hemoculture during 2009 were retrieved from the medical wards, Siriraj Hospital. Demographic data, antimicrobial use, types of bacteria isolated from blood and susceptibilities, patients' comorbidities, 28-day and overall mortality rates were collected and analyzed. Results. There were 229 cases, mean age (SD) of 63.5 (17.2) years and mean (SD) APACHE II score of 24.7 (6.8). The prevalence of first-dose and 24-hour inappropriate antimicrobials was 29.7% and 25.3%, respectively. The 28-day and overall mortality rates between first-dose inappropriate and appropriate antimicrobial were 67.6% versus 60.2% (P = 0.301) and 75.0% versus 68.3% (P = 0.345), consequently. Patients with septic shock and inappropriate first-dose antimicrobials significantly had higher 28-day mortality rate (61.6% versus 41.9%; P = 0.017). Conclusion. Higher mortality rates in bacteremic septic patients were substantially associated with inappropriate first-dose antimicrobials and 3-hour delayed antimicrobial administration after sepsis diagnosis.

Pharmacist interventions on antibiotic use in inpatients with respiratory tract infections in a Chinese hospital

OBJECTIVE

To evaluate the impact of pharmacist interventions on antibiotic use in inpatients with respiratory tract infections in a tertiary hospital in China.

METHOD

Two independent respiratory wards were randomized into control and intervention group. Between July 2009 and April 2010, all inpatients diagnosed with respiratory tract infections were enrolled. Pharmacist interventions were performed on the physicians in the intervention group. The total cost of hospitalization, cost of antibiotics, length of hospital stay and the scores of 6 items of inappropriate antibiotic use (including indication, choice, dosage, dosing schedule, duration and conversion) were analyzed.

RESULTS

The total costs of hospitalization in the intervention group were significant lower compared to the control group ($1442.3 ± 684.9 vs. $1729.6 ± 773.7, P < 0.001), as well as the cost of antibiotics ($832.0 ± 373.0 vs. $943.9 ± 412.0, P = 0.01), and the patients required shorter length of hospital stay (14.2 ± 6.2 vs. 15.8 ± 6.0 days, P = 0.03). The scores with respect to the 6 items of inappropriate antibiotic use were all lower in the intervention group than in the control group.

CONCLUSIONS

Pharmacist interventions, interacted directly with the physicians at ward level, could play an important role in optimizing antibiotic use, thus lead to the reduction in patients' length of hospital stay and health care cost.

Analgesic prescribing practices can be improved by low-cost point-of-care decision support

CONTEXT

Codeine has become a controversial choice for analgesia in children compared with other commonly available drugs.

OBJECTIVES

To evaluate whether an educational campaign shifted resident prescribing patterns away from codeine toward more appropriate analgesics.

METHODS

Our intervention consisted of a pocket-sized reference card given to all trainees and key staff in an inpatient pediatric acute care unit; pediatrics residents also had the option to attend a one-hour lecture. The pocket card recommended against codeine (including rationale) and gave prescription guidance for our institution's preferred formulary alternative analgesics, which include tramadol and hydrocodone. We used inpatient prescribing data to track the prescribing of codeine and alternative medications over time.

RESULTS

Following the interventions, there was a significant decrease in the percentage of patients receiving codeine (13.5% of patients received the drug in the year before, 5.4% in the year after, P < 0.0001). Use of hydrocodone-containing analgesics increased overall during the same period (7.4%-16%, P < 0.0001) as did tramadol use (0.2%-2.6%, P < 0.0001). There were no changes in pain management satisfaction scores.

CONCLUSION

A simple low-cost educational campaign consisting primarily of a pocket guide to analgesics markedly improved analgesic prescribing patterns, and that improvement extended to services not targeted by the didactic component of our educational campaign. Point-of-care decision support by means of a pocket card may be sufficient for effecting change in medication prescribing patterns of trainees.

Antimicrobial use guidelines for treatment of urinary tract disease in dogs and cats: antimicrobial guidelines working group of the international society for companion animal infectious diseases

Urinary tract disease is a common reason for use (and likely misuse, improper use, and overuse) of antimicrobials in dogs and cats. There is a lack of comprehensive treatment guidelines such as those that are available for human medicine. Accordingly, guidelines for diagnosis and management of urinary tract infections were created by a Working Group of the International Society for Companion Animal Infectious Diseases. While objective data are currently limited, these guidelines provide information to assist in the diagnosis and management of upper and lower urinary tract infections in dogs and cats.
