EXECUTIVE SUMMARY
This is the first Point Prevalence Survey of Antimicrobial use inpaediatrics and neonates in Wales performed as part of a comparativeEuropean project (ARPEC) and using appropriate diagnostic categoriesfor these patient groups.
o 391 paediatric and neonatal patients were surveyedo 85 from neonatal or maternity wards (22%)o 306 from paediatric wards (78%)
Overall 104 patients (26.6%) were prescribed a systemicantimicrobial/s
o 102 (26.0%) received a systemic antibacterial/s
o 8 (2%) received a systemic antifungals
o 1 (0.3%) received a systemic antiviral
o 1 (0.3%) received TB drugs
Prescribing was highest on specialist haematology-oncology wards(67%) and lowest on general neonatal medical wards (10%). Ongeneral paediatric medicine wards, 30.4% of patients received anantimicrobial.
On paediatric wards,o The commonest indication for antimicrobials was community-
acquired infection - 75%o The commonest reasons for treatment were:
Bacterial lower respiratory tract infection – 15% Prophylaxis for medical problems – 15% Skin or soft tissue infections – 14% Sepsis – 13%
On neonatal wards,o The commonest indication for antimicrobials was medical
prophylaxis – 59%o The commonest reasons for treatment were:
Prophylaxis for maternal risk factors – 33% Sepsis – 31% Prophylaxis for newborn risk factors – 22%
In neonates the commonest antimicrobials were benzylpenicillin andgentamicin which, between them, accounted for 67% of antimicrobialuse
In paediatrics there was more variability in antimicrobial use, thecommonest agents being 3rd generation cephalosporins that accountedfor 18% of antimicrobial use.
4
Dosing of antimicrobials was variable. Mean gentamicin dosing for the<1 month age group was 4.0 mg/kg/day; while mean dosing for the 2-17 year age group was 7.1 mg/kg/day.

INTRODUCTION
There is relatively little knowledge and understanding about antimicrobial usein paediatrics and neonates. Antimicrobial usage data based on pharmacystock information such as that published by the Welsh AntimicrobialResistance Programme is difficult to interpret due to variable dosing indifferent age groups, and previous European Antimicrobial Point PrevalenceSurveys (PPS) have focused mainly on adults, using methodology designedaround prescribing for adults. With a view to optimizing antimicrobialprescribing in children, the Directorate General for Health and ConsumerPolicy (DG SANCO) of the European Commission funded the project‘Antibiotic Resistance and Prescribing in European Children (ARPEC)http://www.arpecproject.eu/. The paediatric and neonatal PPS builds on theexisting European funded ESAC system on antimicrobial prescribing. TheARPEC work package 5 is lead by Professor Herman Goosens, University ofAntwerp, Belgium and Professor Mike Sharland, St Georges UniversityHospital London.
In Wales, the paediatric and neonatal PPS of antimicrobial prescribing wascarried out on November 18th 2011 to mark European antibacterial awarenessday, and to provide data to the ARPEC survey of antimicrobial prescribing inEuropean children.
The current report provides a simple overview of data for paediatrics andneonates collected as part of the fourth All-Wales Point Prevalence Survey ofantimicrobial usage in secondary care; the data include all antibacterial,antiviral, antifungal, and TB agents, which are collectively described asantimicrobials. However, much of the analysis concentrates on antibacterialprescribing only.

METHODOLOGY
Data were collected by the hospital pharmacists using a pro-forma based onARPEC methodology (for the PPS forms see the Appendix).
The pharmacists were instructed to survey all patients resident on the wardsat 08.00 am on the day of the survey, and to document those receivingantimicrobials; assigning a clinical indication (see Table 1), and a reason fortreatment to each drug. Unlike the adult PPS, pharmacists were also asked toassign a maximum of three underlying diagnosis to each patient (for the listsof ‘Reasons for Treatment and ‘Underlying Diagnosis’ see the Appendix).

2011 PPS DEMOGRAPHICS
391 paediatric and neonatal patients were surveyed 85 of the patients were from neonatal or maternity wards (22%) and
306 were from paediatric wards (78%) 239 of the patients were medical patients (61%) 79 of the patients were surgery patients (20%) 73 of the patients were ICU patients (19%)
Of the 391 patients surveyed in the 2011 PPS, 104 were prescribed asystemic antimicrobial/s (26.6%).
102 were prescribed regimens which included systemic antibacterials,excluding TB regimens (26.0%).
8 were prescribed regimens which included systemic antifungals (2%)
1 was prescribed a regimen that included a systemic antiviral (0.3%)
1 was prescribed a regimen that comprised TB drugs (0.3%)
The age group and gender of the 104 patients prescribed antimicrobials isshown in Figure 1.
44 of patients were 2-17 years in age (42%) 41 of patients were <1 month in age (39%) 19 of patients were 1-23 months in age (18%)
Of the 104 paediatric and neonatal patients prescribed antimicrobials, 61%were male and 39% were female. Data for all hospitals on age group andgender is shown in Appendix Table 1.

Figure 2 shows the proportion of antimicrobial prescribing by ward type.Prescribing prevalence ranged from 67% in the specialist haematology-oncology wards (SPM) to 10% in the general neonatal medical wards(GNMW).
Figure 2: Antimicrobial prescribing by ward types
Key: SPM - Haematology-oncology specialised medical ward; NICU - Neonatal intensive care unit (LI - level 1; L2 -level 2; L3 - level 3); GPM – General paediatric medicine; PS – Paediatric surgery; PICU – Paediatric intensive careunit; GNWM – General neonatal medical ward.
Figure 3 shows the indications assigned to the antimicrobial prescribing byage groups. Note: some patients were prescribed more than one antimicrobialfor more than one indication e.g. A/D = prescribing for a community acquiredinfection and medical prophylaxis.
Treatment for community acquired infections (A) was the most commonindication for antibacterial prescribing in the 2-17 years & 1-23 monthsage groups, accounting for 77% and 68% of prescribing respectively.
For the <1 month age group medical prophylaxis (D) was the mostcommon indication for antibacterial prescribing (46%). (NOTE: medicalprophylaxis is the category used to describe prophylactic/pre-emptiveuse of antimicrobials in neonates with identified maternal or neonatalrisk factors for infection.)
Hospital acquired infections (B) were most common in the <1 monthage group (22%), compared with 10% in the 1-23 months age groupand 2% in the 2-17years group. Hospital acquired infection was definedas ‘symptoms starting 48 hours or more after admission to hospital’.
No antimicrobials were prescribed for surgical prophylaxis in this PPS.

Figure 5 shows the route of administration for systemic antimicrobials by agegroup. For neonates aged <1 month 93% of antimicrobials were administeredparenterally compared to 61% in the 1-23 month age group, and 52% in the 2-17 year age group. Overall, 70% antimicrobials were parenteral and 30% oral.

Figure 6 shows the route of administration for systemic antibacterials by wardtype. For NICUs and general neonatal medical wards >92% of antimicrobialswere administered parenterally compared to 60% for the general paediatricmedicine; this largely reflects the difference in age between the ward types,with <1 month neonates receiving parenteral therapy rather than oral.

Total numbers of antimicrobials prescribed 174
Total numbers of antibacterials prescribed 161
The Top 6 antimicrobials were all antibacterials: Gentamicin, benzylpenicillin,flucloxacillin, cefotaxime, amoxicillin and co-amoxiclav accounted for 60% ofantimicrobial prescribing.
Figure 9 compares antibacterial prescribing in neonatal wards (NICUs andgeneral neonatal medical wards) with prescribing in paediatric wards (generalpaediatric medicine, paediatric surgery, paediatric ICU & specialised medicinewards).
The most notable difference is prescribing of aminoglycosides (mainlygentamicin) and beta-lactamase sensitive penicillins (benzyl penicillin);these two agents accounted for 67% of all antibacterial prescribing inneonates compared with 17% in paediatrics.
For paediatrics, the third generation cephalosporins (cefotaxime,ceftazidime and ceftriaxone) were the most commonly prescribedantibacterial group accounting for 18% of total prescribing. However,there was no clear choice of agent, with prescribing was spreadamongst beta-lactamase resistant penicillins (flucloxacillin),combinations of penicillins including beta-lactamase inhibitors (mainlyco-amoxiclav), and penicillins with an extended spectrum (amoxicillin)and aminoglycosides.

Table 2 shows the 22 different antibacterial combinations prescribed.
51 of the 102 patients in this PPS that were prescribed antibacterialswere prescribed a combination of antibacterials (50%).
The most common antibacterial combination was an aminoglycoside(gentamicin) plus narrow spectrum penicillin (benzylpenicillin); thiscombination accounted for one third of antibacterial combinations.

REASON FOR TREATMENT
Table 3 shows the reason for antibacterial treatment/prophylaxis in paediatrics andneonates e.g. in paediatrics 16 of the 106 antibacterial prescribed were for thetreatment of bacterial lower respiratory tract infection (LRTI). For paediatrics, themost common reasons for treatment/prophylaxis were bacterial LRTI, prophylaxis formedical problems (e.g. chronic lung disease), skin soft tissue infections, and sepsis:Accounting for 57% of antibacterial prescribing in paediatrics.
For neonates, the most common reasons for antibacterial treatment/prophylaxiswere prophylaxis for maternal risk factors e.g. prolonged rupture of membranes,sepsis, and prophylaxis for newborn risk factors e.g. treatment for prematurenewborns: Accounting for 86% of antibacterial prescribing in neonates.

For the treatment of bacterial LRTI in paediatrics, third generation cephalosporins(cefotaxime, ceftazidime and ceftriaxone), combinations of penicillins including beta-lactamase inhibitors (co-amoxiclav), and penicillins with an extended spectrum(amoxicillin) accounted for 63% of prescribing.
For prophylaxis of medical problems in paediatrics prescribing was spread across anumber of antibacterial groups: as this category includes prophylaxis in children withsickle cell disease, urinary tract infection, immunosuppression, nephrotic syndrome,chronic lung disease, rheumatic fever etc. the group is too diverse to make anymeaningful conclusions.
For the treatment of sepsis in paediatric patients, third generation cephalosporins(cefotaxime and ceftriaxone), penicillins with extended spectrum (amoxicillin) andglycopeptides accounted for 86% of prescribing.
For the treatment of skin and soft tissue infections (SSTI) in paediatrics, beta-lactamase resistant penicillins (flucloxacillin), & beta-lactamase sensitive penicillins(benzyl penicillin & phenoxymethyl penicillin) accounted for 80% of prescribing.

VARIATION IN DOSING
Figures 15 the variation in gentamicin dosing for paediatric and neonatal patients;dosing is defined as (dose*times a day)/current weight of the child.
The mean dosing for the <1 month age group was 4.014 mg/kg/day, and the meandosing for the 2-17 year age group was 7.117 mg/kg/day.
For the < 1 age group dosing ranged from 2.9 mg/kg/day to 5.0 mg/kg/day, and forthe 2-17 year age group dosing ranged from 6.9 mg/kg/day to 7.5 mg/kg/day
This small data set shows a wide variation in dosing for gentamicin.

INDICATION CODES FOR NICU/GNMW PPS 2011
A Community acquired infection Symptoms or antibiotics start <48h after admission to hospital
B Hospital acquired infection
Symptoms or antibiotics start 48hafter admission to hospital
B1 Post-operative infection (within 30 days after surgery or
1 year after implant surgery)
B2 IV catheter intervention related infections
B4 Other hospital acquired infection including VAP and CAPD*
B5 Infection present on admission from another hospital
C Surgical prophylaxis** C1 Single dose C2 multiple doses within one day C3 >1 day
D Medical prophylaxis All medical prophylaxis
* VAP= ventilator Associated Pneumonia; CAPD= Continuous Ambulatory peritoneal dialysis
** For surgical patients, administration of prophylactic antimicrobials should be checked in the previous
24 hours in order to encode the duration of prophylaxis as either one dose, multiple doses given on one
day or >1 day.
Type of treatment – E versus T
Empirical treatment (E) = empiric – when the antibiotic is being used as per a localguideline – as a best guess - treatment by means which experience has proved tobe beneficial.
Targeted treatment (T) = based upon microbiological culture and/or sensitivitytesting, the action of the remedies given are directed against the cause of thedisease (e.g. positive blood or sputum culture).
Note down the information which is available at the time of survey (e.g. empirical evenwhen confirmation positive blood culture day after survey)
Ventilated – Note down the status at 8am on the day of the survey.
Inv.V = yes, invasive ventilation
NonInv.V = yes, non-invasive ventilation. These include continuous positive airwaypressure (CPAP), nasal continuous positive airflow pressure (nCPAP) and Bi-LevelPositive Airway Pressure (BiPAP)
No vent. = no ventilation
