The objective of our consensus process was to develop a unique classification of the natural history of scorpion stings and their clinical signs and symptoms. The technique used was an adapted Delphi approach completed by a nominal group meeting. Researchers included in a study received a questionnaire in which we listed all terms used in published studies to characterize clinical consequences of scorpion stings and all signs and symptoms belonging to each class. For each term, experts had to judge the relevance for classifying clinical consequences of scorpion stings and state whether they agreed with the terminology; they could also propose new terms or classes. For each sign or symptom, they had to choose in which class it belonged and also propose if any other sign or symptom should be added. Sixteen researchers participated. Consensus was reached to include four classes: local manifestations; minor systemic manifestations; major systemic manifestations; lethal envenomation. Signs and symptoms associated with each class were defined. A second Delphi round is planned to define indicators to follow the epidemiological situation within and across countries and to develop recommendations for an optimal management of scorpion envenomations. These consensus-based tools should facilitate development of international clinical studies.

This study argues the need for pharmacovigilance to extend its scope to medication errors to improve the safety of drugs. Our results underlined that medication errors are likely to be more serious than ADRs. Our approach based on the collaboration between the pharmacovigilance center and clinicians can be a powerful tool for incorporating error reporting into the culture of medicine.

ABSTRACT:The present work aims to find the epidemiological profile of snakebites in Morocco through a retrospective study of 1,423 snakebite cases that occurred between 1992 and 2007. Data were obtained from medical charts of envenomation at the Poison Control and Pharmacovigilance Center of Morocco. Results revealed that 86% of the snakebites had occurred in rural areas and that males were significantly more affected than females at a sex ratio of 23:20. Furthermore, 35% of the bites happened during the summer, with a peak of 215 cases in June (15.1%). We also discovered that 67.3% of the patients were bitten during the day. The age group that comprised the most agriculturally active persons, from 20 to 44 years old, was the most affected by snakebites (551 cases). In terms of evolution, patients who were at least 60 years of age (8.89%) as well as those who were less than 10 years old (7.50%) presented higher mortality. According to clinical severity grades, the data revealed a 70% predominance of grade 2 cases (430). Deaths had occurred only in patients with grades 3 and 4. Furthermore, grade 4 patients presented 100% mortality whereas grade 3 registered 10.7%. The distribution of snakebites according to administrative regions in Morocco showed a predominance of the Souss-Massa-Daraa region both in terms of frequency (32%) and mortality (72.1%). Our study clearly displayed the severity and extent of the snakebite problem in the country, thus revealing that public health authorities should give more attention to this serious situation.
