[Algorithms for the identification of hospital stays due to osteoporotic femoral neck fractures in European medical administrative databases using ICD-10 codes: A non-systematic review of the literature]. / Algorithmes d'identification des séjours pour fracture du col du fémur d'origine ostéoporotique dans les bases médico-administratives européennes utilisant la CIM-10 : revue non systématique de la littérature.

BACKGROUND: Osteoporotic hip fractures (OHF) are associated with significant morbidity and mortality. The French medico-administrative database (SNIIRAM) offers an interesting opportunity to improve the management of OHF. However, the validity of studies conducted with this database relies heavily on the quality of the algorithm used to detect OHF. The aim of the REDSIAM network is to facilitate the use of the SNIIRAM database. The main objective of this study was to present and discuss several OHF-detection algorithms that could be used with this database. METHODS: A non-systematic literature search was performed. The Medline database was explored during the period January 2005-August 2016. Furthermore, a snowball search was then carried out from the articles included and field experts were contacted. The extraction was conducted using the chart developed by the REDSIAM network's "Methodology" task force. RESULTS: The ICD-10 codes used to detect OHF are mainly S72.0, S72.1, and S72.2. The performance of these algorithms is at best partially validated. Complementary use of medical and surgical procedure codes would affect their performance. Finally, few studies described how they dealt with fractures of non-osteoporotic origin, re-hospitalization, and potential contralateral fracture cases. CONCLUSIONS: Authors in the literature encourage the use of ICD-10 codes S72.0 to S72.2 to develop algorithms for OHF detection. These are the codes most frequently used for OHF in France. Depending on the study objectives, other ICD10 codes and medical and surgical procedures could be usefully discussed for inclusion in the algorithm. Detection and management of duplicates and non-osteoporotic fractures should be considered in the process. Finally, when a study is based on such an algorithm, all these points should be precisely described in the publication.

Densitometría ósea y predicción de riesgo de fractura de la cadera / Bone densitometry and risk prediction of the hip fracture / Densitométrie osseuse et prédiction du risque de fracture de la hanche

Este trabajo es el resultado de una investigación multicéntrica que sirvió de ensayo clínico para la validación de un densitómetro óseo (Degos 7032). El estudio consistió en la comparación de dos grupos de personas: uno de 50 voluntarios aparentemente sanos y 39 pacientes con fractura de la cadera. Para comparar ambos grupos se utilizó para la evaluación la prueba F de Fischer si la diferencia entre las varianzas de la densidad ósea era significativa en el extremo distal del radio por el método de absorciometría de simple fotón. A continuación se comparó mediante la prueba de la t de Student (para valores no apareados). La diferencia entre las medias fue significativa. De aquí se concluyó que la magnitud de la densidad ósea es un índice que permite diferenciar los dos grupos y sirve para monitorear el riesgo de fractura de la cadera y anticiparse al trauma de la fractura.

This paper is the result of a multicenter investigation that served as a clinical assay for the validation of a bone densitometer (Degos 7032). The study was based on the comparison of two groups of persons: one of the 50 apparently sound volonteers and the other of 39 patients with hip fracture. To compare both groups it was used for the evaluation the F Fischer's test if the difference between the bone density variances (CMO-width) was significant in the distal extreme of the ratio by using the method of simple photon absorptiometry. Then, another comparison was made by the t of Student test (for unmatched values). The difference between the means was significant. It was concluded that the bone density magnitude is an index that allow to differentiate both groups and that it may be used to monitor the hip fracture risk and to anticipate to the trauma caused by fracture.

Ce travail est le résultat d'une recherche multicentrique servant d'essai clinique pour la validation d'un densitomètre osseux (Degos 7032). L'étude a consisté à une comparaison de deux groupes de personnes: l'un de 50 volontaires apparemment sains et l'autre de 39 patients avec fracture de la hanche. Afin de comparer les deux groupes, on a utilisé une épreuve F de Fischer si la différence entre les variances de la densité osseuse (CMO/large) était significative dans l'extrème distal du radius par la méthode d'absorptiométrie du simple photon. Après on a comparé au moyen de l'essai de la t de Student (pour les valeurs no appariées). La différence entre les moyennes a été significative. On en conclut que la magnitude de la densité osseuse c'est un indice qui permet de différencier les deux groupes et sert pour le monitorage du risque de fracture de la hanche et pour anticiper au trauma.
