Antibiotic Prescribing Patterns in Paediatric Primary Care in Italy: Findings from 2012-2018

State of the Art of Antimicrobial and Diagnostic Stewardship in Pediatric Setting

Antimicrobial stewardship programs (ASPs) and diagnostic stewardship programs (DSPs) are essential strategies for effectively managing infectious diseases and tackling antimicrobial resistance (AMR). These programs can have a complementary impact, i.e., ASPs optimize antimicrobial use to prevent resistance, while DSPs enhance diagnostic accuracy to guide appropriate treatments. This review explores the current landscape of ASPs and DSPs in pediatric care, focusing on key factors, influencing their development, implementation, and evaluation across various settings. A multidisciplinary approach is necessary, involving multiple healthcare professionals to support comprehensive stewardship practices in pediatric care. No single intervention suits all settings, or even the same setting, in different countries; interventions must be tailored to each specific context, considering factors such as hospital capacity, patient complexity, and the parent-child dynamic. It is essential to educate caregivers on optimal antibiotic use through clear, concise messages adapted to their socioeconomic status and level of understanding. The cost-effectiveness of ASPs and DSPs should also be assessed, and standardized metrics should be employed to evaluate success in pediatric settings, focusing on outcomes beyond just antibiotic consumption, such as AMR rates. This manuscript further discusses emerging opportunities and challenges in ASP implementation, offering insights into future research priorities. These include large-scale studies to evaluate the long-term impact of ASPs, cost-effectiveness assessments of pediatric-specific diagnostic tools, and the integration of artificial intelligence to support clinical decision making. Addressing these areas will enhance the effectiveness and sustainability of ASPs, contributing to global efforts to combat AMR and improve pediatric health outcomes.

Treatment of acute pharyngitis in children: an Italian intersociety consensus (SIPPS-SIP-SITIP-FIMP-SIAIP-SIMRI-FIMMG)

Sore throat represents one of the main causes of antibiotic overprescription in children. Its management is still a matter of debate, with countries considering streptococcal pharyngotonsillitis a benign and self-limiting condition and others advocating for its antibiotic treatment to prevent suppurative complications and acute rheumatic fever. Italian paediatricians frequently prescribe antibiotics on a clinical basis regardless of microbiological results. Moreover, broad-spectrum antibiotics are inappropriately prescribed for this condition. In this regard, an intersociety consensus conference was issued to promote the judicious use of antibiotic therapy in paediatric outpatient settings. A systematic review of the literature was performed, and updated recommendations were developed according to the GRADE methodology. Antibiotic treatment with amoxicillin (50 mg/kg/day) for 10 days is recommended in all children with proven streptococcal pharyngitis. Benzathine-penicillin could be prescribed in children with impaired intestinal absorption or inability to tolerate enteral intake and in those at high risk of suppurative complications with low compliance to oral therapy. In children with suspected amoxicillin allergy, third-generation cefalosporins for five days are recommended in low-risk patients, and macrolides are recommended in high-risk ones. Candidates for tonsillectomy due to recurrent pharyngitis could be treated with amoxicillin-clavulanic acid, clindamycin, or combined therapy with amoxicillin plus rifampicin for four days, in an attempt to avoid surgery.

Appropriateness of antibiotic prescribing in paediatrics: retrospective controlled study assessing a multifaceted intervention in Northern Italy in a 7-year period

BACKGROUND

Academic detailing, audit and feedback, and peer comparison have been advocated as effective ways to promote appropriateness of prescribing and antimicrobial stewardship (AMS). This study explored the effectiveness of a multifaceted intervention aimed at supporting the appropriateness of antibiotic prescribing in paediatrics.

METHODS

Over the course of 7 years, all 89 paediatricians of the Local Health Authority (LHA) of Reggio Emilia (530 000 residents) were provided with scientific literature focused on antimicrobial resistance and the appropriateness of use of specific antibiotics, together with local data on antimicrobial resistance and prescribing reports comparing each paediatrician with colleagues in the same district and with local averages. Prescribing rates of specific target antibiotics/classes of antibiotics were evaluated by comparing Reggio-Emilia with the other seven LHAs of the Emilia-Romagna Region (control area), adjusting for prescriptions during a 2-year baseline period.

RESULTS

A significant increase in the rate of amoxicillin prescriptions (91 more per 1000 children/year) was observed in the intervention area compared with the control area along with a significant reduction in the rate of amoxicillin+clavulanate prescriptions (70 fewer per 1000 children/year) and a significant increase in the ratio of their prescription rates. No differences were observed in cephalosporin and macrolide prescription rates and overall antibiotic prescriptions.

CONCLUSIONS

Improvements in prescribing appropriateness were observed. This study confirms the importance of an audit and feedback approach through small group meetings supported by scientific literature, local resistance data and prescribing reports. Such approach should always be considered as part of multifaceted interventions to promote AMS.

Retrospective Analysis of Patient-Reported Adverse Drug Reactions in an Italian Allergy Unit: ALLERG-RAF Study

INTRODUCTION

The Italian Medicines Agency indicates that about 5% of hospital admissions are due to adverse drug reactions (ADRs). Several factors are recognized to be associated with an increased risk for ADRs, such as the female gender and polytherapy. The aim of this study was to retrospectively analyze the suspected ADRs reported by patients during the anamnestic interview at the Allergy Unit.

PATIENTS AND METHODS

ALLERG-RAF study is a retrospective analysis of the medical records of patients evaluated in the Allergy Unit of ASST Spedali Civili and the University of Brescia from 2000 to 2016. The inclusion criteria were age ≥18 years and medical consultation requested for suspected ADRs. Data relating to the patient's intrinsic characteristics, the drug supposed to be the cause, and the prescribed pharmacological therapy were collected. Pseudonymized data from each patient were collected in an informatics database.

RESULTS

From 2000 to 2016, 35,817 accesses to the Allergy Unit were made, and 2,171 unique events related to a suspected ADR were collected in 1,840 patients. More than two-thirds of the reports concerned females (70.4%). Antibiotics were involved in the majority of the self-reported suspected ADRs (48.7%), particularly beta-lactams (61.1%). Anti-inflammatory drugs, mainly NSAIDs, were second in incidence and suspected in 25.2% of reports. As a site of ADR manifestation, most of the reported reactions involve the skin. No clinical sequelae were reported.

CONCLUSIONS

Our results underline the importance of patient reporting in pharmacovigilance. Furthermore, gender gap data emphasizes the importance of the gender-specific medicine approach.

Leading reasons for antibiotic prescriptions in pediatric respiratory infections: influence of fever in a primary care setting

BACKGROUND

Antibiotic overuse in children is a significant public health concern, as it can lead to the emergence and spread of antibiotic-resistant bacteria. Although respiratory infections account for most antibiotic prescriptions in children, many of these infections are viral and do not require antibiotics. In this study, we aimed to investigate the use of antibiotics in children with respiratory infections in a primary care setting and to explore the possible role of fever on antibiotic prescription.

METHODS

We conducted a prospective observational study that evaluated preschool children aged 0-5 years who were assessed by their primary care pediatricians for respiratory infectious diseases between October 2019 and March 2021. The study involved 69 public primary care pediatricians and a total of 678 pediatric episodes for respiratory infections.

RESULTS

Amoxicillin/clavulanate was the most frequently prescribed drug. Bronchitis accounted for most of inappropriate antibiotic prescriptions (73%). Furthermore, the presence of fever was associated with a ~ 300% increase in the likelihood of prescribing antibiotics for respiratory infections that do not typically require antibiotics.

CONCLUSION

Our findings emphasize the need for adherence to international guidelines and recommendations in the primary care of children to reduce unnecessary antibiotic use and prevent the development of antibiotic resistance. This study also underscores the potential relevance of new studies to evaluate antibiotic prescription attitudes in other clinical settings and geographical areas.

Assessing the burden of bronchiolitis and lower respiratory tract infections in children ≤24 months of age in Italy, 2012-2019

Background

Bronchiolitis is the most common lower respiratory tract infection (LRTI) in children and is mainly caused by the Respiratory Syncytial Virus (RSV). Bronchiolitis presents seasonally and lasts about five months, usually between October to March, with peaks of hospitalizations between December and February, in the Northern Hemisphere. The burden of bronchiolitis and RSV in primary care is not well understood.

Materials and methods

This retrospective analysis used data from Pedianet, a comprehensive paediatric primary care database of 161 family paediatricians in Italy. We evaluated the incidence rates (IR) of all-cause bronchiolitis (ICD9-CM codes 466.1, 466.11 or 466.19), all-cause LRTIs, RSV-bronchiolitis and RSV-LRTIs in children from 0 to 24 months of age, between January 2012 to December 2019. The role of prematurity (<37 weeks of gestational age) as a bronchiolitis risk factor was evaluated and expressed as odds ratio.

Results

Of the 108,960 children included in the study cohort, 7,956 episodes of bronchiolitis and 37,827 episodes of LRTIs were recorded for an IR of 47 and 221 × 1,000 person-years, respectively. IRs did not vary significantly throughout the eight years of RSV seasons considered, showing a seasonality usually lasting five months, between October and March, while the peak of incidence was between December and February. Bronchiolitis and LRTI IRs were higher during the RSV season, between October and March, regardless of the month of birth, with bronchiolitis IR being higher in children aged ≤12 months. Only 2.3% of bronchiolitis and LRTI were coded as RSV-related. Prematurity and comorbidity increased the risk of bronchiolitis; however, 92% of cases happened in children born at term, and 97% happened in children with no comorbidities or otherwise healthy.

Conclusions

Our results confirm that all children aged ≤24 months are at risk of bronchiolitis and LRTI during the RSV season, regardless of the month of birth, gestational age or underlying health conditions. The IRs of bronchiolitis and LRTI RSV-related are underestimated due to the poor outpatient epidemiological and virological surveillance. Strengthening the surveillance system at the paediatric outpatient level, as well as at the inpatient level, is needed to unveil the actual burden of RSV-bronchiolitis and RSV-LRTI, as well as to evaluate the effectiveness of new preventive strategies for anti-RSV.

Retrospective Analysis of the Real-World Use of Topical Antimicrobials in the Paediatric Population with Impetigo in Italy: Focus on the Role of Ozenoxacin 1% Cream

Using electronic data from a large population-based network of Family Paediatricians (Pedianet), we aimed to describe the use of topical antimicrobials, including ozenoxacin 1% cream, in impetigo in children in Italy. We included 2929 children aged 6 months–14 years from 2016 to 2019 with at least one episode of impetigo treated with topical antimicrobials. Overall, 3051 cases of impetigo were included in the analysis. Treatment started in most cases on the same day as the impetigo diagnosis and lasted around eight days. In about 8% of the cases, a systemic antibiotic was prescribed after the topical antimicrobial, usually after 4–14 days. In this study, ozenoxacin was used in 8% of the cases. Treatment duration was significantly shorter for patients prescribed ozenoxacin compared to the whole study population (median of six vs. seven days, respectively). In contrast, the rate of treatment failure was similar. Very few adverse reactions were identified.

Watchful Waiting in Pediatric Acute Otitis Media: A Real Practice Approach or an Intangible Desideratum?

Acute otitis media (AOM) in children is one of the leading causes of health care visits and antibiotic prescriptions worldwide. The overall aim of the current study is twofold: 1. to analyze and discuss the antibiotic prescription patterns in AOM in children without complications or risk factors and 2. to assess to what extent the watchful-waiting approach is a real practice or a mere desideratum. We performed an electronic search in the PubMed and Embase databases from 2013 to 2023 to capture original research studies investigating antibiotic prescribing patterns for AOM in children. Among the 12 papers included in the analysis, the antibiotic prescription rate ranged from 44.8% to 98%. Our study reveals similarities regarding the use of amoxicillin as a first-line antibiotic in pediatric AOM, but also discrepancies in the watchful-waiting approach attitude and in the choice of second or third-line antimicrobial agents. The proportion of cases managed with the watchful-waiting approach ranged from 7.5% (Australia) to 55.2% (Finland). Denmark was the only country reporting penicillin V as a first-choice regimen for children with AOM, which fulfils the guidelines' recommendations. The most unsatisfying rate of amoxicillin use was recorded in Japan, contrary to the recommendations of local guidelines. The use of quinolones was reported in two out of twelve studies, with the highest proportion in Japan, where tosufloxacin was used in 21.4% of the total number of cases. The duration of the antibiotic regimens was analyzed in three out of twelve papers. Since global antibiotic overuse contributes to the emergence of antibiotic resistant bacteria, new strategies are needed to increase the rate of watchful waiting and to promote the judicious use of antibiotics.

Health facility practices and patterns of prescription influencing health-seeking behaviour among caregivers of children diagnosed with pneumonia in Endebess Sub-county, Kenya

Background

Pneumonia accounts for 16% of all child deaths in Kenya, and it is the second killer of children under the age of five. Pneumonia burden is attributed to inadequate access to healthcare and poor health-seeking by caregivers. Endebess caregivers report delays of 1-14 days and subject their children to medicine from shops before visiting a hospital, as evidenced by the history of the presenting illness in patient files. In addition, irrational prescription has been demonstrated regardless of clinical guidelines. This study explored health facility practices and drug prescription patterns that influence health-seeking behaviour in Endebess Sub-county, Kenya.

Methods

A cross-sectional study involving 273 caregivers accompanied by a qualitative study on 24 health personnel was conducted from May to August 2019. Using a simple random sampling technique, a questionnaire was administered to caregivers visiting the health facilities. Key informant interview guides were also conducted with health care personnel. Quantitative data were analysed using logistic regression, whereas qualitative data were analysed by searching for emerging themes on health facility practices and prescription patterns across health facilities.

Results

Overall, stratification by health facility practices revealed that there were numerous significant results at the level of P<0.001, including the availability of drugs, administration of a starting dose, type of drug prescribed, willingness to recommend the facility, place caregiver seeks treatment (P=0.005) and facility of choice (P=0.001), which all influenced willingness to revisit the hospital. In relation to health information, the significant results at the level of P<0.001 included adequate instructions, the confidence of the caregiver to give the correct dosage at home, satisfaction levels and shared decision making on choices of antibiotic therapy (P=0.005) were associated with a higher willingness to revisit the hospital. There was a varied pattern of prescriptions for antibiotics. Consistently the odds of willingness to revisit the hospital increased among caregivers who had an injection medication prescribed for their children (P=0.380; odds ratio, OR=2.06, 95% confidence interval, CI=0.41-10.42) relative to those on oral medication.

Conclusions

There is a need for strict control of prescribing antibiotics in children under five years. Shared decision making on the choice of therapy should not be limited to chronic illnesses.

Antibiotic Prescription Patterns in the Paediatric Primary Care Setting before and after the COVID-19 Pandemic in Italy: An Analysis Using the AWaRe Metrics

The containment measures following COVID-19 pandemic drastically reduced airway infections, but they also limited the access of patients to healthcare services. We aimed to assess the antibiotic prescription patterns in the Italian paediatric primary care setting before and after the containment measures implementation. For this retrospective analysis, we used a population database, Pedianet, collecting data of patients aged 0–14 years enrolled with family paediatricians (FP) from March 2019 to March 2021. Antibiotic prescriptions were classified according to WHO AWaRe classification. An interrupted time series evaluating the impact of the containment measures implementation on the monthly antibiotic index, on the access to watch index, and on the amoxicillin to co-amoxiclav index stratified by diagnosis was performed. Overall, 121,304 antibiotic prescriptions were retrieved from 134 FP, for a total of 162,260 children. From March 2020, the antibiotic index dropped by more than 80% for respiratory infections. The Access to Watch trend did not change after the containment measures, reflecting the propensity to prescribe more broad-spectrum antibiotics for respiratory infections even during the pandemic. Similarly, co-amoxiclav was prescribed more often than amoxicillin alone for all the diagnoses, with a significant variation in the trend slope for upper respiratory tract infections prescriptions.

Reduction in broad-spectrum antimicrobial prescriptions by primary care pediatricians following a multifaceted antimicrobial stewardship program

BACKGROUND

Since 2016, following the Italian "National Plan to Contrast Antimicrobial Resistance", Campania Region has implemented an antimicrobial stewardship program, including the obligation to associate an appropriate International Classification of Diseases-9 code to each antibiotic prescription, the publication of schemes for empirical antibiotic therapy and educational interventions.

METHODS

To evaluate the impact of these interventions on the prescribing habits of family pediatricians, we conducted a retrospective cohort study (January 2016-December 2020), including all patients registered in an associate practice of Primary Care Pediatricians. We collected data on antibiotic prescriptions through a specific study management software; our primary outcomes were the annual prescription rates, calculated for both the number of patients in follow-up and the number of medical consultations, and the annual prescription rates for selected antibiotic classes and molecules. To investigate the hypothesis that chronic conditions would be associated with an increased rate of prescription, we also tested the association between underlying conditions and the number of antibiotics received.

RESULTS

During the study period, 2,599 children received 11,364 antibiotic prescriptions (mean 4.37, SD 4.28). From 2016 to 2020 we observed a substantial reduction in both the annual prescription rate per 100 patients (9.33 to 3.39; R ²= 0.927, p = 0.009), and the annual prescription rate per 100 medical consultations (25.49 to 15.98; R ²= 0.996, p < 0.01). The prescription rates of Amoxicillin-Clavulanate (50.25 to 14.21; R ²= 0.983, p = 0.001) and third generation Cephalosporins (28.43 to 5.43; R ²= 0.995, p < 0.01) significantly decreased; we didn't find significant modifications in the prescription rates of Amoxicillin and Quinolones; finally, we observed a trend toward reduction in the prescription of Macrolides. No statistical association was found between antibiotics prescribing frequency and history of chronic diseases.

DISCUSSION

Following the implementation of the regional interventions on antimicrobial stewardship, we observed a substantial reduction in the overall antibiotic prescription per patients and per medical consultations, with a statistically significant reduction in the use of broad-spectrum molecules. Considering the results of our analysis, new guidance and training interventions addressed to specialists in the primary care sector should be implemented to further limit antibiotic resistance.
