Antimicrobial Use in a Swedish Pediatric Hospital: Results From Eight Point-prevalence Surveys Over a 15-Year Period (2003-2017)

Point prevalence surveys of antibiotic prescribing in children at a tertiary hospital in a resource constraint, low-income sub-Saharan African country-the impact of an antimicrobial stewardship program

BACKGROUND

Resistance to multiple antibiotics by several pathogens has been widely described in children and has become a global health emergency. This is due to increased use by parents, caregivers, and healthcare providers. This study aims to describe the prevalence rates of antibiotic prescribing, ascertain the impact of antimicrobial stewardship programs, and target improving the quality of antibiotic prescribing in the paediatric population over time in a hospital.

METHOD

A point prevalence survey of antibiotic use was performed yearly for 4 years to monitor trends in antibiotic prescribing. Data from all patients admitted before 8 a.m. on the day of the PPS were included. A web-based application designed by the University of Antwerp was used for data entry, validation, and analysis ( http://www.global-pps.com ).

RESULTS

A total of 260 children, including 90 (34.6%) neonates and 170 (65.4%) older children, were admitted during the four surveys. Overall, 179 (68.8%) patients received at least one antibiotic. In neonates, the prevalence of antibiotic use increased from 78.9 to 89.5% but decreased from 100 to 58.8% in older children. There was a reduction in the use of antibiotics for prophylaxis from 45.7 to 24.6%. The most frequently prescribed antibiotic groups were third generation cephalosporins and aminoglycosides. The most common indications for antibiotic prescription were sepsis in neonates and central nervous system infection in older children. The documentation of reason in notes increased from 33 to 100%, while the stop-review date also increased from 19.4 to 70%.

CONCLUSION

The indicators for appropriate antibiotic prescription improved over time with the introduction of antibiotic stewardship program in the department.

Antibiotic use in pediatric acute care hospitals: an analysis of antibiotic consumption data from Germany, 2013-2020

BACKGROUND

Antimicrobial stewardship (AMS) programs are effective tools for improving antibiotic prescription quality. Their implementation requires the regular surveillance of antibiotic consumption at the patient and institutional level. Our study captured and analyzed antibiotic consumption density (ACD) for hospitalized pediatric patients.

METHOD

We collected antibacterial drug consumption data for 2020 from hospital pharmacies at 113 pediatric departments of acute care hospitals in Germany. ACD was calculated as defined daily dose (DDD, WHO/ATC Index 2019) per 100 patient days (pd). In addition, we analyzed the trends in antibiotic use during 2013-2020.

RESULTS

In 2020, median ACD across all participating hospitals was 26.7 DDD/100 pd, (range: 10.1-79.2 DDD/100 pd). It was higher at university vs. non-university hospitals (38.6 vs. 25.2 DDD/100 pd, p < 0.0001). The highest use densities were seen on oncology wards and intensive care units at university hospitals (67.3 vs. 38.4 DDD/100 pd). During 2013-2020, overall ACD declined (- 10%) and cephalosporin prescriptions also decreased (- 36%). In 2020, cephalosporins nevertheless remained the most commonly dispensed class of antibiotics. Interhospital variability in cephalosporin/penicillin ratio was substantial. Antibiotics belonging to WHO AWaRe "Watch" and "Reserve" categories, including broad-spectrum penicillins (+ 31%), linezolid (+ 121%), and glycopeptides (+ 43%), increased over time.

CONCLUSION

Significant heterogeneity in ACD and prescription of different antibiotic classes as well as high prescription rates for cephalosporins and an increased use of reserve antibiotics indicate improvable antibiotic prescribing quality. AMS programs should urgently prioritize these issues to reduce antimicrobial resistance.

Prescribing Patterns in Pediatric General Wards and Their Association with Prescribing Errors: A Retrospective Observational Study

PURPOSE

There are only limited data on drug utilization patterns in pediatric inpatients, especially on general wards. The aim of the study was to describe prescribing patterns and their associations with prescribing errors in a university children's hospital in the German-speaking part of Switzerland.

METHOD

This was a subanalysis of a retrospective single-center observational study. Patient characteristics and drug use of 489 patients with 2693 drug prescriptions were associated with prescribing errors. Drugs were categorized by the Anatomic Therapeutic Chemical Classification System (ATC), patients were categorized by age group according to European Medicines Agency guidelines, and prescribing errors were analyzed by type [Pharmaceutical Care Network Europe (PCNE) classification] and severity of error [adapted National Coordinating Council for Medication Error Reporting (NCC MERP) index].

RESULTS

The most frequently prescribed ATC classes were nervous system (N) (42.6%), alimentary system (A) (15.6%), and anti-infective drugs (J) (10.7%). Eighty-two percent of patients were prescribed an analgesic. Most drugs were prescribed for oral (47%) or intravenous (32%) administration, but the rectal route was also frequent (10%). The most frequently prescribed drugs were paracetamol, metamizole, and ibuprofen. The high number of metamizole prescriptions (37% of patients were prescribed metamizole) is typical for German-speaking countries. Older pediatric patients were prescribed more drugs than younger patients. A statistically significant difference was found in the rate of potentially harmful errors across age groups and for gender; children between 2 and 11 years had a higher rate of potentially harmful errors than infants under 2 years (p = 0.029) and female patients had a higher rate of potentially harmful errors than male patients (p = 0.023). Recurring errors were encountered with certain drugs (nalbuphine, cefazolin).

CONCLUSIONS

Our study provides insight into prescribing patterns on pediatric general wards in a university children's hospital in Switzerland and highlights some areas for future research. Especially, the higher risk for prescribing errors among female pediatric patients needs further investigation.

Antibiotic consumption among hospitalized neonates and children in Punjab province, Pakistan

BACKGROUND

Periodic surveillance of antibiotic consumption in the form of point prevalence studies is a quick and robust methodology to evaluate prescribing trends in hospitals. The current study was undertaken to document antibiotic consumption among neonates and children from hospitals in Pakistan.

METHODS

This large multicenter study using the World Health Organization standardized methodology and AWaRe (Access, Watch, and Reserve) classification examined antibiotic consumption for suspected bacterial infection among neonates and children admitted hospitals in Punjab, Pakistan.

RESULTS

A total of 708 beds of children wards of the 16 health facilities were examined. Almost all (97%) hospitalized children were prescribed antibiotics on the day of the assessment with 2.6 antibiotics per patient. The three most common indications were respiratory tract infections (31.58%), sepsis (26.52%), and prophylaxis for medical problems (10.30%). The three most frequently prescribed antibiotics were ceftriaxone (24.2%), amikacin (23.2%), and ampicillin (16.7%). Almost half of the antibiotics were prescribed from the 'Access' (49.5%) and 'Watch' (45.5%) categories under the AWaRe classification. However, no antimicrobial was prescribed from the 'Reserved' category.

CONCLUSIONS

Our findings indicate that empirical antimicrobials use among hospitalized children is highly prevalent in Pakistan. The utilization of 'Watch' category of antimicrobials is frequent, stressing immediate action.

Appropriateness of Antibiotic Prescribing in United States Children's Hospitals: A National Point Prevalence Survey

BACKGROUND

Studies estimate that 30%-50% of antibiotics prescribed for hospitalized patients are inappropriate, but pediatric data are limited. Characterization of inappropriate prescribing practices for children is needed to guide pediatric antimicrobial stewardship.

METHODS

Cross-sectional analysis of antibiotic prescribing at 32 children's hospitals in the United States. Subjects included hospitalized children with ≥ 1 antibiotic order at 8:00 am on 1 day per calendar quarter, over 6 quarters (quarter 3 2016-quarter 4 2017). Antimicrobial stewardship program (ASP) physicians and/or pharmacists used a standardized survey to collect data on antibiotic orders and evaluate appropriateness. The primary outcome was the percentage of antibiotics prescribed for infectious use that were classified as suboptimal, defined as inappropriate or needing modification.

RESULTS

Of 34 927 children hospitalized on survey days, 12 213 (35.0%) had ≥ 1 active antibiotic order. Among 11 784 patients receiving antibiotics for infectious use, 25.9% were prescribed ≥ 1 suboptimal antibiotic. Of the 17 110 antibiotic orders prescribed for infectious use, 21.0% were considered suboptimal. Most common reasons for inappropriate use were bug-drug mismatch (27.7%), surgical prophylaxis > 24 hours (17.7%), overly broad empiric therapy (11.2%), and unnecessary treatment (11.0%). The majority of recommended modifications were to stop (44.7%) or narrow (19.7%) the drug. ASPs would not have routinely reviewed 46.1% of suboptimal orders.

CONCLUSIONS

Across 32 children's hospitals, approximately 1 in 3 hospitalized children are receiving 1 or more antibiotics at any given time. One-quarter of these children are receiving suboptimal therapy, and nearly half of suboptimal use is not captured by current ASP practices.

Quality Analysis of Antimicrobial Restriction Policy in Pediatrics

Background: Antimicrobial stewardship programs (ASPs) are coordinated programs developed in recent years to promote the appropriate use of antimicrobials and reduce microbial resistance. One important action for a successful ASP is the implementation of an antimicrobial policy restriction. Objective: The study analyzed the quality of target-antimicrobial requisitions after the introduction of an antimicrobial policy restriction for children. Methods: We conducted a retrospective study in a neonatal intensive care unit (NICU) and three pediatric intensive care units (PICUs). An ASP was implemented in October 2016, and 14 target antimicrobials were selected to be prescribed after pre-approval by a pediatric infectious disease specialist. All requisitions were analyzed according to indication, antimicrobial type, dose, duration, and collection of cultures before administration. There were no exclusion criteria for requisition analysis. Results: Between October 2016 and December 2017, 1,173 patients were admitted to the units with 120 requisitions of target antimicrobials. Sepsis (43/120; 35.8%) was the most common indication, followed by respiratory infections (23/120; 19.2%) and infections in two or more sites (11/120; 9.2%). The most common target antimicrobials requested were meropenem (68/120; 56.7%), amphotericin B lipid formulations (12/120; 10%), teicoplanin (11/120; 9.2%), and linezolid (11/120; 9.2%). In 98 (81.7%) cases, previous cultures before antimicrobial administration were collected. An infectious agent was detected in 52 of the 98 cultures (53.1%), and Gram-negative and Gram-positive bacteria represented 50% and 26.9% of all positive samples, respectively. Besides, 111 (92.5%) requisitions were approved. In five refused requisitions, a narrow-spectrum antimicrobial was prescribed after further discussion; four were refused due to lack of information, and in one case, the de-escalation of the antimicrobial was possible. No mistake regarding dosage and duration was detected. Conclusions: We found a high-quality rate of target antimicrobial requisition. Antimicrobial policy restriction could contribute to improving the quality of antimicrobial prescription, even in NICUs and PICUs.

Analysis of antibiotic treatment of children in a Shanghai tertiary hospital based on point prevalence surveys

Background

Misuse and overuse of antibiotics by physicians in the treatment of children is common in China. This study aimed to reveal the overall use of antibiotics to treat children hospitalized in four types of pediatric wards.

Methods

Seven independent point prevalence surveys (PPSs) were conducted in Shanghai Children’s Hospital of Shanghai Jiao Tong University over the period 2012 to 2018. Pediatric ward types were defined general pediatric medical, pediatric surgical, pediatric intensive care units (PICU), and neonatal.

Results

A total of 3975 pediatric patients were included in the study, of which 63.9% received at least one dose antibiotic. The top five classes of antibiotics administered were cephalosporins (43.8%, n = 1743), penicillins (13.2%, n = 526), carbapenems (8.7%, n = 347), nitroimidazoles (7.1%, n = 281) and macrolides (6.5%, n = 257). The five most commonly used generic antibiotics were cefuroxime (14.9%, n = 594), ceftriaxone (9.7%, n = 387), cefotaxime (9.0%, n = 358), meropenem (8.1%, n = 320) and ampicillin/sulbactam (6.0%, n = 239). Meropenem was among top five antibiotics prescribed in the general pediatric, PICU and neonatal wards and sixth in the pediatric surgical wards. Of all children on antibiotics, 23.4% received prophylactic treatment, and prophylaxis accounted for 68.1% of indications for treatment in the pediatric surgical wards.

Conclusions

Given that over-treatment with third-generation cephalosporins and carbapenems has been associated with treatment-resistant infections, the prescription of these drugs should be strictly controlled and monitored, and measures should be taken to improve the management of surgical prophylaxis in hospitalized children in China.

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.
