Comparison Between Pediatricians and Family Practitioners in the Use of the Prokinetic Cisapride for Gastroesophageal Reflux Disease in Children

Abstract

Objective. The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition and the European Society of Pediatric Gastroenterology, Hepatology and Nutrition have recently issued treatment guidelines for the use of cisapride in children. Our hypothesis was that cisapride is misused in the community and is not prescribed according to suggested recommendations. Therefore, the aim of this study was to evaluate the knowledge of pediatricians and family practitioners regarding the prescribing practice and adverse effects of cisapride.

Methods. A standardized questionnaire was sent to a randomly selected group of pediatricians and family practitioners in Northern Israel. The questionnaire was designed to evaluate the knowledge of the physician regarding the treatment of gastroesophageal reflux disease and the use of cisapride in children (indications, dosages, duration of treatment, limitations in certain age groups, the need for pretreatment laboratory tests, interactions with other drugs, and contraindications). Replies were scored from 0 to 100 according to the treatment guidelines of both the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition and the European Society of Pediatric Gastroenterology, Hepatology and Nutrition. In addition, 2 questions dealt with the subjective efficacy of the drug and its adverse events.

Results. The knowledge scores were 62% and 51% in the pediatricians and family practitioners, respectively. Other major findings were as follows: 1) 40% of pediatricians and 65% of family practitioners do not prescribe the recommended dose of cisapride, 2) 6% of pediatricians and 42% of family practitioners prescribe cisapride for infantile colic, 3) only 50% of pediatricians and 22% of family practitioners were aware of possible interactions with macrolides, and 4) only 31% of pediatricians and 54% of family practitioners were aware that cisapride might cause prolongation of the QT interval. Only minor adverse events were reported.

Conclusions. The knowledge of both pediatricians and family practitioners in the use of cisapride in children is suboptimal. It is essential to improve the education of community physicians to reduce the potential for adverse events arising from the misuse of this prokinetic agent.
