Abstract
BackgroundThe list of medical devices (MD) eligible for reimbursement under the Compulsory Health Insurance in Morocco is set by Ministerial Order comprising 869 items between life-support equipment, external prostheses, and implants. The objective of the present study is to analyze the nomenclature of implantable medical devices (IMD) appearing on this list and compare them with the global nomenclature of MD (GMDN) and the European nomenclature of MD (EMDN). MethodsThe study deals with (i) the mapping of the codes of the IMD list with 170 DM per cardinality and (ii) a metric identification by Sørensen-Dice coefficient of terminological similarity of the IMD with respect to the two databases. ResultsThe 170 IMD codes are mapped onto 493 terms in the GMDN and 344 terms in the EMDN. The 37.7% of implants are mapped to more than or equal to 2 terms of GMDN while 36.5% are mapped to more than or equal to 2 terms to the EMDN. The comparison of cardinality distributions has revealed no significant difference (P=0.430) between the two databases. The implants examined are divided into 11 categories whose strong similarity is given to active cardiovascular implants in the EMDN database with simDice=0.534. ConclusionHealthcare authorities need to align with nomenclature standards to improve interoperability and rely on a more efficient and rational regulatory process.
