Utilisation de la CRP capillaire aux urgences pédiatriques de Pau : étude descriptive

Abstract : Introduction: The increasing admission in paediatric emergency and antimicrobial resistance are making point-of-care C reactive protein tests useful in eliminating severe bacterial infection faced by a fever. The aim of this study was to describe the use of capillary CRP within Pau’s Hospital paediatric department, the prescription of additional examinations and to identify certain fever characteristics allowing the production of a protocol. Methods and tools: This was a descriptive transversal study carried out from February 28th, 2018 to February 6th, 2019 in Pau’s Hospital paediatric emergency department. A survey, filled for every patient (from 0 to 15 years and 3 months) who benefited from a capillary CRP, collected the main characteristics of the fever, the complementary examinations considered, and the result of the capillary CRP. Three criteria were analysed together to study the indication of a capillary CRP: fever less than 5 days, good tolerance and returning home considered. Results: 204 surveys were analysed. The average age was 3 years and 2 months. The average CRP was 33 mg/l. In 41% of cases, the fever lasted for 48 to 120 hours with an average CRP of 39.3 mg/l (p=0.09). Fever was well tolerated in 76% of cases with an average CRP of 29.5 mg/l (p=0.07). The most common accompanying signs were: ENT signs (27%), respiratory (25%), digestive (20%), naked fever (20%) and single rhinitis (18%). The capillary CRP enabled a reduction of the complementary examinations considered (p=1.99E-15). Returning home was considered in 91% of the cases with an average CRP of 29.9 mg/l (p=0.04). The value of the capillary CRP when the 3 criteria were met was 23 mg/l (p=1,56E-4). Conclusion: Fever characteristics highlighted could serve as a basis for the creation of a protocol to realise capillary CRP. Capillary CRP would reduce complementary examinations.
