Aplicación de técnicas de clustering para caracterizar proveedores de servicios de mantenimiento / Applying the clustering technique for characterising maintenance outsourcing

Objetivo Utilizar técnicas de clustering para caracterizar a los proveedores de servicios de mantenimiento de una institución de salud. Métodos El estudio analiza el inventario del equipamiento perteneciente a 7 áreas pilotos (264 equipos médicos). Se aplican técnicas de clustering usando 26 variables. Entre las más significativas: el tiempo de respuesta (RT), la duración de las intervenciones (DR), la disponibilidad y el tiempo de cambio de estado (TAT). Resultados La obsolescencia del equipo biomédico en promedio es de 0,78. Se identifican 4 grupos de proveedores de servicios. Grupos (1 y 3): Mejor desempeño, menores valores de TAT, RT y DR; cuyos proveedores son: O, L, C, B, I, S, H, F, G; representan el 56 por ciento del total; con valores de TAT entre: 1,4 días

Objective Using clustering techniques for characterising companies providing health institutions with maintenance services. Methods The study analysed seven pilot areas' equipment inventory (264 medical devices). Clustering techniques were applied using 26 variables. Response time (RT), operation duration (OD), availability and turnaround time (TAT) were amongst the most significant ones. Results Average biomedical equipment obsolescence value was 0.78. Four service provider clusters were identified: clusters 1 and 3 had better performance, lower TAT, RT and DR values (56 percent of the providers coded O, L, C, B, I, S, H, F and G, had 1 to 4 day TAT values:

[ effect of medical equipment maintenance management system implementation on Valie-Asr hospital costs situated in Arak 2006]

Medical equipment improvement and tremendous expenditure is allocated costs annually, so that optimum and proper maintenance management of equipment would have outstanding effects on health and treatment of medical training and research economies of the country. Present research was implemented aiming to examine effect of the medical equipment maintenance management systems on the hospital setting expenditures. In an interventional research, the model of medical equipment maintenance management system implemented in Imam Khomeini Hospital was examined precisely and based on appropriate software for Vali-e-Asr Hospital was designed. According to the model for all available medical instruments in Vali-e-Asr Hospital with usage of more than 5 years [240 medical equipment]; all costs were recorded in 2006 and compared with previous year [2005]. There wasn't any training for medical equipment operators and for its implementation necessity on 21.7% of equipment in the installation and start up phase with for 83.7% of equipments the operator was not fixed using of medical equipment maintenance management system, the repair events decreased from 78 events in 2005 to 58 events in 2006. Vali-e-Asr hospital recorded costs for maintenance and repair of medical equipment in 2006 was 801765375 Rials [Iran] which decreased to 513212912 Rials [Iran] according to accurate calculation of costs and auditing by medical equipment engineer and shows 36% saving in expenditures by medical equipment maintenance management system. Medical equipment computer-based maintenance, management system implementation and also using of medical engineers potentialities in hospital are necessary
