Groups 2
Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Intervention: Diagnostic Algorithm | diagnostic algorithm including a standardised clinical assessment, a Point-of-care C-reactive protein test, and safety netting advice~diagnostic algorithm: Guidance will be part of a diagnostic algorithm which includes clinically guided point-of-care C-reactive protein testing and safety netting advice to inform parents on what to expect and what to look out for. A selection of clinical features will be assessed and recorded by the physician in the patient's health record and on the e-CRF, including the clinical decision tree (clinician's gut feeling, body temperature, dyspnea).~The safety-netting advice will be supported by a parent information booklet, based on previous research (the When should I worry-interactive booklet (a guide to Coughs, Colds, Earache \& Sore Throats), the Mijn kind heeft koorts booklet (Eefje de Bont, www.thuisarts.nl), and the Caring for children with coughs-leaflet (information about how to look after a child who has a cough and when to see the doctor)). | 466 | 2,988 | OG000 | ClinicalTrials.gov |
| Group 2 | Usual Care | In the control arm, patients will receive 'usual care' left at the discretion of the treating physician.~Apart from the general training session for all participating physicians they have attended prior to recruitment and randomization, physicians in the control arm will not receive additional tools.~They are expected (but not forced) to follow the Belgian guidelines (as described in BAPCOC National guidelines and the RIZIV consensus meeting Rational use of antibiotics in children). | 817 | 3,762 | OG001 | ClinicalTrials.gov |
