Twenty four years of oral and maxillofacial surgery malpractice claims in Spain: patient safety lessons to learn

PurposeOral and maxillofacial surgery (OMS) malpractice risk is of special interest due to both the aesthetic component of some procedures and the complexity of the pathologies involved. This study aims to identify relevant factors involved in OMS professional liability (PL) claims to help achive better management of risks and improve patient safety.MethodsWe performed a retrospective analysis of 315 OMS claims opened between 1990 and 2014 from the database of the PL Department of the Catalonian Council of Medical Colleges, and identified their clinical, economical and juridical characteristics.ResultsOMS showed a high rate of compensation (33.8%). Dental implant surgery, third molar surgery and rhinoplasty presented the greatest exposure to claims, and in these cases, lack of osteointegration of dental implants, neurologic injury of inferior dentoalveolar/lingual nerves and a poor aesthetic result were the most frequently compensated sequelae. Statistically, significant association was found between this perioperative complications group and the presence of PL. Poorly documented patient information (informed consent document) was also significantly related with PL outcome.ConclusionsOMS is a specialty of medium risk for claims, especially oral surgery cases. Surgical complications, such as neurologic damage after oral/head and neck procedures and poor aesthetic results, do occur and deserve special attention to improve patient safety, as well as patient-information procedure.
