Brief Summary
Many children every year present to the Emergency Department (ED) at The Royal Children's Hospital (RCH) with cellulitis (skin infection). If it is mild, the children can go home with oral antibiotic treatment. If it is complicated and severe, these children are admitted to hospital for intravenous (IV, through a drip) antibiotic treatment. There is a middle group with uncomplicated moderate/severe cellulitis who require IV antibiotics but who are not acutely unwell. In order to determine whether it is just as effective for children with uncomplicated moderate to severe cellulitis to receive antibiotic treatment at home (via Hospital-In-The-Home) as it is to receive antibiotic treatment in hospital, there is a need to conduct a larger study and randomly assign children to receive either HITH or hospital ward care.
The primary research question to be addressed is:
In children with moderate/severe uncomplicated cellulitis, is the failure rate at 2 days following the first dose of antibiotic non-inferior for children treated with IV antibiotics at home compared to the failure rate at 2 days following the first dose for children treated with IV antibiotics in hospital?
Detailed Description
INTRODUCTION AND BACKGROUND Adults with cellulitis commonly have IV antibiotics administered as outpatients, whereas most children are admitted to hospital. Based on a small amount of literature, it is known that some children with moderate/severe cellulitis can also be safely be treated at home.This study will include all children with uncomplicated moderate/severe cellulitis and will therefore demonstrate whether all children with uncomplicated moderate/severe cellulitis can be effectively treated at home.
If the study demonstrates that it is just as effective to treat these children in the home, it has the potential to impact on the child and family's quality of life (QOL) as well as hospital resource management.
PRIMARY OBJECTIVE To compare the failure rate of IV antibiotic treatment of children treated at home (iv ceftriaxone) with those treated in hospital (iv flucloxacillin) in the first 2 days of treatment following the first dose given in the ED in children with moderate/severe cellulitis (Moderate/severe: defined in this study, as those assessed by ED doctor to need iv antibiotics)
SECONDARY OBJECTIVES
To compare:
Time to no progression of cellulitis Time to discharge: number of days (including fractions of days) from the time of arrival in ED to the time the patient no longer needs hospital-based interventions/care, whether in hospital or at home Readmission rate Representation to ED Length of stay in ED Duration of IV antibiotics Rates of IV cannula needing at least one resiting Complications of cellulitis: development of abscess requiring drainage after starting IV antibiotics, bacteraemia Adverse events
Microbiology:
Rate of ceftriaxone susceptibility in bacteria isolated from a nasal or skin swab of the affected area
Rate of S. aureus nasal carriage (methicillin-sensitive and methicillin-resistant) collected within 48 hours, after 7-14 days, 3 months and 1 year after starting antibiotics
Rate of resistant bacteria present in stool samples collected within 48 hours, after 7-14 days, 3 months and 1 year after starting antibiotics. Rates of clinical infection with resistant organisms up to 1 year after starting antibiotics
Differential effect of narrow spectrum (flucloxacillin) and broad spectrum (ceftriaxone) on the nasal and gastrointestinal microbiome from nasal swabs and stool samples collected within 48 hours, after 7-14 days, 3 months and 1 year after starting antibiotics.
Costs of hospital versus HITH treatment: including costs of beds, consumables, nursing and medical time, and overheads including administrative time, information technology, use of hospital cars Quality of life (QOL) indicators Clinical assessments of cellulitis in terms of presence of systemic features, surface area affected (longest length axis multiply by the longest perpendicular axis measured in cm2), severity of swelling (judged by clinician as any one of the following: mild, moderate or severe), intensity of erythema (judged by clinician from a scale of 0 to 5, 0=no erythema and 5=severe and whether the function of the affected area is impaired
STUDY METHODOLOGY ED clinicians (senior doctors, junior doctors or nurse practitioners) will identify patients with moderate/severe cellulitis presenting to RCH ED, at the point of triage or during clinical assessment. The consent will be for randomization, data collection and follow up which is not part of routine practice. Randomisation to the location of treatment is the essential difference from normal clinical practice. Where parents do not give consent, the ED clinician will make the decision on where the patient should be treated.
INTERVENTIONS Although in this proposed study the intervention is treating children at home, currently, based on the prospective observational study, 50% of children with uncomplicated moderate/severe cellulitis are already being sent home by ED clinicians to receive daily IV antibiotics at home. The only new intervention is the randomisation process which will provide a high level of evidence for this practice which has become a standard practice in ED. The researcher or ED clinician will have access to randomization software and perform the randomisation process. Patients who are randomised to HITH will be prescribed iv ceftriaxone (50mg/kg once daily) as per current practice and those randomised to the ward will be prescribed iv flucloxacillin (50mg/kg 6 hourly). On insertion of the IV cannula, the ED clinician will obtain a blood culture. If there is skin breakdown, a skin swab would be done as per routine clinical practice. Prior to commencing IV antibiotics. In addition, the researcher or ED clinician will ask parents to take 2 photos of the cellulitis area using their own camera/phone (if available) after the affected area is demarcated with indelible ink with a tape measure placed along side the area affected. This will be helpful for the reviewing doctor the following day to judge whether there is an improvement.
The first dose of antibiotics will be commenced in ED. For children assigned to hospital ward treatment, the child will be transferred to the ward and the IV infusion continued. Children assigned to the HITH will complete their first dose in ED before going home. The management after this point will be as per usual practice. The responsible ward doctor will review and make all management decisions for patients admitted to the ward whereas the HITH registrar will review the patients on HITH. The research assistant (RA) (a paediatric registrar) will meet with the child and their parent(s) within 24 hours of consent being obtained to answer any further questions parents or participants may have about the study.
Currently, there are no guidelines on when to start IV antibiotic in cellulitis. The investigators' recommendation is provided under section 'Inclusion criteria' and this reflects consensus among RCH ED clinicians. Some patients who did not require IV antibiotics may be recruited but they will exist in both groups.
A nasal swab and stool sample will be requested at four different time points: 1) within 48 hours of the first antibiotic dose; 2) 7-14 days after starting antibiotics; 3) 3 months after starting antibiotics; and 4) 1 year after starting antibiotics. At each time point, additional information will be collected: previous overseas travel, previous hospital admissions, household member who has been admitted to hospital overseas, other antibiotic use, other infections, medical visits or hospital admissions. These samples are optional and do not affect participation in the study.
As per normal practice, patients will be switched to oral therapy after 2-4 days of IV antibiotics, when there is clinical improvement of the cellulitis. Based on the current prospective study, both HITH patients and ward patients are switched to oral antibiotics when there is a reduction in fever, swelling, erythema and improvement of function of affected area (eg. Previously limping, now walking). Once changed to oral antibiotics (as per RCH clinical practice guidelines; cephalexin 25mg/kg 6 hourly, total dose may be combined and divided to twice daily), patients are usually discharged from hospital care and normally not followed up any further in hospital. In this study, the investigators are offering all participants a follow up in clinic 7-14 days (by the RA who is a paediatric registrar) after discharge from hospital. Parents will be requested to bring a stool sample from the patient to the clinic review but this is not mandatory.
