Acute gastroenteritis remains a frequent illness in infants and children with still important morbidity and mortality rates. Oral rehydratation solutions (ORS) and early refeeding are the main recommendations. Indication of drugs remains limited. Objective. - To evaluate the management of acute diarrhea by private practice pediatricians of France. Methods. - A questionnaire concerning ORS, dietary formula, antidiarrheal diet, antibiotherapy, antidiarrheal drugs was sent to all 2907 private pediatricians of France. Results. - Six hundred twenty-nine questionnaires were analyzed (22%). Three hundred and ninety-seven pediatricians (63%) prescribed systematically an ORS, 294 (47%) changed formula, 412 (66%) prescribed a regimen. Antibiotic was prescribed after coproculture (81%), when glairy and bloody diarrhea (65%), associated infectious disease (63%), toxi-infectious syndrome (42%) or immunodeficiency were present (28%). Most pediatricians (97%) prescribed at least one drug: diosmectite (84%), Lactobacillus acidophilus (63%), Saccharoinyces boulardii (62%), racecadotril (62%), loperamide (28%), attapulgite de Mormoiron (26%), nifuroxazide (20%). Drugs were prescribed more often for their effectiveness than for comfort. Conclusion. - This study demonstrates the discrepancies that remain between recommendations and practical care in the treatment of acute diarrhea in children. Private French pediatricians often prescribe drugs. (C) 2004 Elsevier SAS. Tous droits reserves.
