Expanding Existing Antimicrobial Stewardship Programs in Pediatrics: What Comes Next

Telemedicine-based antibiotic stewardship program in pediatrics: study protocol of a stepped wedge cluster randomized trial-the TeleKasper study

BACKGROUND

Overuse and misuse of antibiotics is one of the driving factors of antimicrobial resistance, a growing global health threat. The use of antibiotics is particularly high in children. Even though the implementation of antibiotic stewardship programs (ASP) in pediatrics has been shown to reduce antibiotic use, this implementation has been limited to large university hospitals in Germany. Telemedicine applications might be an effective approach to implement ASP in non-university settings.

METHODS

This protocol details the TeleKasper study (Telemedical Competence Network "Antibiotic Stewardship in Pediatrics"). Tele-Kasper is a stepped-wedge cluster-randomized trial that will be conducted across non-university children's hospitals in Germany. The intervention consists of a telemedical consultation service in the form of a network in different German areas, using an app as a communication tool. The primary outcome will be a 20% reduction in overall antibiotic consumption measured using defined daily doses per 100 patient days.

DISCUSSION

The TeleKasper study aims to implement and evaluate a prototype for a nationwide antibiotic stewardship program by telemedical means in pediatric departments in non-university hospitals in Germany to promote rational antibiotic use and improve medical care for infections.

PACTA-Ped: Antimicrobial stewardship programme in a tertiary care hospital in Spain

INTRODUCTION

Fighting against antimicrobial resistance is a current priority, and further efforts need to be made to improve antimicrobial prescribing and reduce the spread of infections in paediatric care settings.

METHODS

We conducted a prospective longitudinal study on the use of antimicrobials from the time the antimicrobial stewardship programme (ASP) was introduced in January 2016 to December 2017 (period 2 [P2]) in our children's hospital. We compared the obtained results on antimicrobial prescribing with retrospective data from the period preceding the introduction of the ASP (2014-2015, period 1 [P1]). The sample consisted of paediatric inpatients who received broad-spectrum antimicrobials, antifungals or intravenous antibiotherapy lasting more than 5 days. We compared the use of antimicrobials in P1 versus P2.

RESULTS

A total of 160 patients were included during P2. The antibiotics for which a recommendation was made most frequently were meropenem (41.6%) and cefotaxime (23.4%). In 45% of care episodes, the consultant recommended "no change" to the prescribed antimicrobial. The final rate of acceptance of received recommendations by the prescribing physicians was 89%. We found average decreases of 27.8% in the days of treatment per 1000 inpatient days and 22.9% in the number of antimicrobial starts per 1000 admissions in P2. The use of carbapenems, cephalosporins and glycopeptides decreased in P2 compared to P1. The average annual cost of antimicrobial treatment decreased from є150 356/year during P1 to є98 478/year in P2.

CONCLUSION

Our ASP achieved a significant decrease in the use of broad-spectrum antibiotics and antifungals. The costs associated with antimicrobial prescribing decreased following the introduction of the ASP, which was a cost-effective action in this study period.

Regional Perspective of Antimicrobial Stewardship Programs in Latin American Pediatric Emergency Departments

Antibiotic stewardship (AS) programs have become a priority for health authorities to reduce the number of infections by super-resistant microorganisms. The need for these initiatives to minimize the inadequate use of antimicrobials is essential, and the election of the antibiotic in the emergency department usually impacts the choice of treatment if the patients need hospital admission, becoming an opportunity for antibiotic stewardship. In the pediatric population, broad-spectrum antibiotics are more likely to be overprescribed without any evidence-based management, and most of the publications have focused on the prescription of antibiotics in ambulatory settings. Antibiotic stewardship efforts in pediatric emergency departments in Latin American settings are limited. The lack of literature on AS programs in the pediatric emergency departments in Latin America (LA) limits the information available. The aim of this review was to give a regional perspective on how pediatric emergency departments in LA are working towards antimicrobial stewardship.

Assessment of the Plans to Optimize Antimicrobial Use in the Pediatric Population in Catalan Hospitals: The VINCat Pediatric PROA SHARP Survey

In Spain, many programs have been introduced in recent years to optimize antimicrobial stewardship in pediatric care (known as pediatric PROA). However, information on the current situation of these programs is scarce. The present study assesses current antimicrobial use in pediatric care in the hospitals of Catalonia affiliated with the VINCat pediatric PROA group. Between December 2020 and January 2021, an electronic survey related to the design and use of PROA was administered to members of PROA teams in our hospital network. The survey was conducted at 26 hospitals. Twelve percent of the hospitals had pediatric PROA in operation, 42% were included in adult PROA, and 46% carried out pediatric PROA activities but not as part of an established program. At 81%, the pediatric PROA team included a pediatrician, in 58% a pharmacist, and in 54% a microbiologist. The main activities were monitoring the use of antimicrobials and bacterial resistance. Twenty-seven percent measured indicators regularly. The VINCat Pediatric PROA group's hospitals have implemented measures for optimizing antimicrobial stewardship, but few have a pediatric PROA program in place. Specific measures and indicators must be defined, and the resources available should be increased. The development of pediatric PROA should be monitored in the coming years.

Characteristics of antifungal utilization for hospitalized children in the United States

Objective

To characterize antifungal prescribing patterns, including the indication for antifungal use, in hospitalized children across the United States.

Design

We analyzed antifungal prescribing data from 32 hospitals that participated in the SHARPS Antibiotic Resistance, Prescribing, and Efficacy among Children (SHARPEC) study, a cross-sectional point-prevalence survey conducted between June 2016 and December 2017.

Methods

Inpatients aged <18 years with an active systemic antifungal order were included in the analysis. We classified antifungal prescribing by indication (ie, prophylaxis, empiric, targeted), and we compared the proportion of patients in each category based on patient and antifungal characteristics.

Results

Among 34,927 surveyed patients, 2,095 (6%) received at least 1 systemic antifungal and there were 2,207 antifungal prescriptions. Most patients had an underlying oncology or bone marrow transplant diagnosis (57%) or were premature (13%). The most prescribed antifungal was fluconazole (48%) and the most common indication for antifungal use was prophylaxis (64%). Of 2,095 patients receiving antifungals, 79 (4%) were prescribed >1 antifungal, most often as targeted therapy (48%). The antifungal prescribing rate ranged from 13.6 to 131.2 antifungals per 1,000 patients across hospitals (P < .001).

Conclusions

Most antifungal use in hospitalized children was for prophylaxis, and the rate of antifungal prescribing varied significantly across hospitals. Potential targets for antifungal stewardship efforts include high-risk, high-utilization populations, such as oncology and bone marrow transplant patients, and specific patterns of utilization, including prophylactic and combination antifungal therapy.

Antimicrobial stewardship program in pediatric medicine

The rising threats from antimicrobial resistance due to inappropriate utilization of antimicrobial agents in health care including the pediatric population has been a topic of concern at the global level for the last several decades. The antimicrobial stewardship program (ASP) is a multidisciplinary institutional initiative focusing primarily on the improvement of antimicrobial prescribing practices and limiting inappropriate use. ASPs play an important role in the implementation of healthcare strategies in pediatrics worldwide to reduce antimicrobial resistance. Many published reports demonstrate how adapted ASPs in pediatrics result in improvement of unnecessary antimicrobial utilization, decreasing drug resistance and treatment failure, minimization of adverse clinical outcomes, decreasing healthcare costs and hospital length of stay, and optimization of diagnostic strategies. However, some barriers in pediatric ASP still exist. This narrative review describes core elements of ASP, the impact of implemented ASPs on pediatric healthcare, and challenges of pediatric ASP as seen by the authors.

Sustainability of Handshake Stewardship: Extending a Hand Is Effective Years Later

BACKGROUND

Children's Hospital Colorado created a unique method of antimicrobial stewardship, called handshake stewardship, that effectively decreased hospital anti-infective use and costs in its pilot year (2013). Handshake stewardship is distinguished by: (1) the lack of prior authorization; (2) a review of all prescribed anti-infectives; (3) a shared review by the physician and the pharmacist; and (4) a daily, rounding-based, in-person approach to supporting providers. We sought to reevaluate the outcomes of the program after 5 years of experience, totaling 8 years of data.

METHODS

We retrospectively measured anti-infective (antibiotic, antiviral, antifungal) use hospital-wide by unit and by drug for an 8-year period spanning October 2010 to October 2018. Aggregated monthly use was measured in days of therapy per thousand patient days (DOT/1000 PD). The percentage of children admitted ever receiving an anti-infective was also measured, as well as severity-adjusted mortality, readmissions, and lengths of stay.

RESULTS

Hospital-wide mean anti-infective use significantly decreased, from 891 (95% confidence interval [CI] 859-923) in the pre-implementation phase to 655 (95% CI 637-694) DOT/1000 PD in post-implementation Year 5; in a segmented regression time series analysis, this was a rate of -2.6 DOT/1000 PD (95% CI -4.8 to -0.4). This is largely attributable to decreased antibacterial use, from 704 (95% CI 686-722) to 544 (95% CI 525 -562) DOT/1000 PD. The percentage of children ever receiving an anti-infective during admission likewise declined, from 65% to 52% (95% CI 49-54). There were no detrimental effects on severity adjusted mortality, readmissions, or lengths of stay.

CONCLUSIONS

The handshake method is an effective and sustainable approach to stewardship.

Effectiveness and safety of mandatory antimicrobial indications and durations and a pharmacist-driven 48-hour time-out in a pediatric hospital

PURPOSE

To evaluate the effectiveness and safety of mandatory antimicrobial indications and durations (MAID) and a pharmacist-driven 48-hour time-out in a pediatric hospital.

METHODS

MAID and a 48-hour time-out were implemented on February 14, 2017. Antibiotic days of therapy (DOT) per 1,000 patient days were compared between the pre- and postperiod for select antibiotics using unadjusted Poisson models. A prepost comparison was used to compare antimicrobial stewardship program (ASP) intervention rates between time periods. A 2-step process, including distribution of a discontinuation (DC) report to pharmacists and ASP-prompted reorders, was instituted to reduce unintentional antimicrobial discontinuation with MAID. ASP-prompted reorders occurred only when a discrepancy persisted between the order and provider-desired duration. Missed antimicrobial doses were identified by ASP and the institutional event reporting system. Safety of MAID was assessed by reviewing the rate and details of ASP-prompted reorders and missed antimicrobial doses.

RESULTS

A significant decrease in DOT per 1,000 patient days was observed for cefazolin (39.7 to 36.9; P < 0.001), ampicillin (39.9 to 35.7; P < 0.001), clindamycin (38.2 to 35.9; P < 0.001), ceftriaxone (46.5 to 43.4; P < 0.001), and meropenem (8.7 to 6.6; P < 0.001) following implementation. No change in ASP intervention rate occurred between the pre- and postperiod (16.9 vs 16.8%; P = 0.94). With MAID, ASP-prompted reorder occurred on 7.3% of orders. Unintentional discontinuations resulting in missed antimicrobial doses occurred in 3 orders (0.07%); no patient harm resulted.

CONCLUSION

MAID and a 48-hour time-out significantly reduced DOT of select antibiotics. No patient harm occurred with the 2-step safety process.

Effects of a Paediatric Antimicrobial Stewardship Program on Antimicrobial Use and Quality of Prescriptions in Patients with Appendix-Related Intraabdominal Infections

The effectiveness of antimicrobial stewardship programs (ASP) in reducing antimicrobial use (AU) in children has been proved. Many interventions have been described suitable for different institution sizes, priorities, and patients, with surgical wards being one of the areas that may benefit the most. We aimed to describe the results on AU and length of stay (LOS) in a pre-post study during the three years before (2014–2016) and the three years after (2017–2019) implementation of an ASP based on postprescription review with feedback in children and adolescents admitted for appendix-related intraabdominal infections (AR-IAI) in a European Referral Paediatric University Hospital. In the postintervention period, the quality of prescriptions (QP) was also evaluated. Overall, 2021 AR-IAIs admissions were included. Global AU, measured both as days of therapy/100 patient days (DOT/100PD) and length of therapy (LOT), and global LOS remained unchanged in the postintervention period. Phlegmonous appendicitis LOS (p = 0.003) and LOT (p < 0.001) significantly decreased, but not those of other AR-IAI diagnoses. The use of piperacillin–tazobactam decreased by 96% (p = 0.044), with no rebound in the use of other Gram-negative broad-spectrum antimicrobials. A quasisignificant (p = 0.052) increase in QP was observed upon ASP implementation. Readmission and case fatality rates remained stable. ASP interventions were safe, and they reduced LOS and LOT of phlegmonous appendicitis and the use of selected broad-spectrum antimicrobials, while increasing QP in children with AR-IAI.

Benefits of a Pediatric Antimicrobial Stewardship Program in Antimicrobial Use and Quality of Prescriptions in a Referral Children's Hospital

OBJECTIVES

To evaluate the results of the first 24 months of a postprescription review with feedback-based antimicrobial stewardship program in a European referral children's hospital.

STUDY DESIGN

We performed a pre-post study comparing antimicrobial use between the control (2015-2016) and the intervention periods (2017-2018) expressed in days of therapy/100 days present. Quality of prescriptions was evaluated by quarterly cross-sectional point-prevalence surveys. Length of stay, readmission rates, in-hospital mortality rates, cost of systemic antimicrobial agents, and antimicrobial resistance rates were included as complementary outcomes.

RESULTS

Total antimicrobial use and antibacterial use significantly decreased during the intervention period (P = .002 and P = .001 respectively), and total antifungal use remained stable. A significant decline in parenteral antimicrobial use was also observed (P < .001). In 8 quarterly point-prevalence surveys (938 prescriptions evaluated), the mean prevalence of use of any antimicrobial among inpatients was 39%. An increasing trend in the rate of optimal prescriptions was observed after the first point-prevalence survey (P = .0898). Nonoptimal prescriptions were more common in surgical than in medical departments, in antibacterial prescriptions with prophylactic intention, and in empirical more than in targeted treatments. No significant differences were observed in terms of mortality or readmission rates. Only minor changes in antimicrobial resistance rates were noted.

CONCLUSIONS

Our antimicrobial stewardship program safely decreased antimicrobial use and expenditure, and a trend toward improvement in quality of prescription was also observed.

Antibiotic utilization in hospitalized children under 2 years of age with influenza or respiratory syncytial virus infection - a comparative, retrospective analysis

BACKGROUND

Infections due to Respiratory Syncytial Virus (RSV) and Influenza virus (FLU) are leading causes of hospitalization in young children. Yet, there is little data on factors associated with antibiotic use in these patients.

METHODS

We conducted a retrospective, single-center study of all patients below 2 years of age hospitalized between 2014 and 2018. We compared children with RSV infection to children with FLU infection analyzing clinical characteristics and factors contributing to an increased rate of antimicrobial utilization.

RESULTS

RSV infection was diagnosed in 476/573 (83.1%), FLU in 95/573 (16.6%), and RSV-FLU-co-infection in 2/573 (0.3%) patients. Median age was lower for RSV compared to FLU (4 vs. 12 months; p < 0.0001). Children with RSV had longer hospitalization (5 vs. 4 days; p = 0.0023) and needed oxygen more frequently (314/476 vs. 23/95; p < 0.0001) than FLU patients. There was no significant difference in the overall antibiotic utilization between RSV and FLU patients (136/476 vs. 21/95; p = 0.2107). Logistic regression analyses revealed that septic appearance on admission (odds ratio [OR] 8.95, 95% confidence interval [CI] 1.5-54.1), acute otitis media (OR 4.5, 95% CI 2.1-9.4), a longer oxygen therapy (OR 1.40; 95% CI 1.13-1.74) and a higher C-reactive protein (CRP) (OR 1.7, 95% CI 1.5-2.0) were significantly associated with antibiotic use in both groups, but not age or pneumonia.

CONCLUSIONS

In our cohort, the rate of antibiotic utilization was comparable between RSV and FLU patients, while for both groups distinct clinical presentation and a high CRP value were associated with higher antibiotic use.

Pediatric Antimicrobial Stewardship Programs: Current Perspectives

With the rapid growth of the field of pediatric antimicrobial stewardship, there has been a marked increase in the establishment of programs dedicated to this specialty. Shared objectives of all pediatric antimicrobial stewardship programs (ASPs) include optimization of antibiotic use and improvement in clinical outcomes for children, while certain core operational strategies and metrics used to measure program effectiveness are typically utilized by pediatric ASPs. Antimicrobial stewardship is the responsibility of every individual who prescribes, dispenses, and administers antibiotics to children, and pediatric ASP principles are rooted in collaboration and cooperation. Pediatric ASPs are uniquely suited to meet the needs of the local populations they serve and the environments within which they practice while also fostering an awareness of the interconnected global nature of pediatric stewardship. As such, pediatric ASPs are well positioned to confront the evolving challenges of antimicrobial overuse and resistance.

The current state of antifungal stewardship among pediatric antimicrobial stewardship programs

OBJECTIVE

To characterize the current state of antifungal stewardship practices and perceptions of antifungal use among pediatric antimicrobial stewardship programs (ASPs).

DESIGN

We developed and distributed an electronic survey, which included 17 closed-ended questions about institutional antifungal stewardship practices and perceptions, among pediatric ASPs.

PARTICIPANTS

ASP physicians and pharmacists of 74 hospitals participating in the multicenter Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS) Collaborative.

RESULTS

We sent surveys to 74 hospitals and received 68 unique responses, for a response rate of 92%. Overall, 63 of 68 the respondent ASPs (93%) reported that they conduct 1 or more antifungal stewardship activities. Of these 68 hospital ASPs, 43 (63%) perform prospective audit and feedback (PAF) of antifungals. The most common reasons reported for not performing PAF of antifungals were not enough time or resources (19 of 25, 76%) and minimal institutional antifungal use (6 of 25, 24%). Also, 52 hospitals (76%) require preauthorization for 1 or more antifungal agents. The most commonly restricted antifungals were isavuconazole (42 of 52 hospitals, 80%) and posaconazole (39 of 52 hospitals, 75%). Furthermore, 33 ASPs (48%) agreed or strongly agreed that antifungals are inappropriately used at their institution, and only 25 of 68 (37%) of ASPs felt very confident making recommendations about antifungals.

CONCLUSIONS

Most pediatric ASPs steward antifungals, but the strategies employed are highly variable across surveyed institutions. Although nearly half of respondents identified inappropriate antifungal use as a problem at their institution, most ASPs do not feel confident making recommendations about antifungals. Future studies are needed to determine the rate of inappropriate antifungal use and the best antifungal stewardship strategies.

Threatened efficiency not autonomy: Prescriber perceptions of an established pediatric antimicrobial stewardship program

BACKGROUND

Implementing antimicrobial stewardship programs (ASPs) can be challenging due to prescriber resistance. Although barriers to implementing new ASPs have been identified, little is known about how prescribers perceive established programs. This information is critical to promoting the sustainability of ASPs.

OBJECTIVE

To identify how prescribers perceive an established pediatric inpatient ASP that primarily utilizes prior authorization.

METHODS

We conducted a cross-sectional survey administered from February through June 2017 in a large children's hospital. The survey contained closed- and open-ended questions. Descriptive statistics and thematic content analysis approaches were used to analyze responses.

RESULTS

Of 394 prescribers invited, 160 (41%) responded. Prescribers had an overall favorable impression of the ASP, believing that it improves the quality of care (92.4% agree) and takes their judgment seriously (73.8%). The most common criticism of the ASP was that it threatened efficiency (26.0% agreed). In addition, 68.7% of respondents reported occasionally engaging in workarounds. Analysis of 133 free-text responses revealed that prescribers perceived that interacting with the ASP involved too many phone calls, caused communication breakdowns with the dispensing pharmacy, and led to gaps between approval and dispensing of antibiotics. Reasons given for workarounds included not wanting to change therapy that appears to be working, consultant disagreement with ASP recommendations, and the desire to do everything possible for patients.

CONCLUSIONS

Prescribers had a generally favorable opinion of an established ASP but found aspects to be inefficient. They reported engaging in workarounds occasionally for social and emotional reasons. Established ASPs should elicit feedback from frontline prescribers to optimize program impact.
