The extraordinary importance of the services sector for the economy both in production and employment cannot be denied. As a result, there have been both demands for an increase in Service Operations Management (SOM) research since the 1980s on the one hand, and, on the other, predictions that such an increase will take place [e.g.]. And yet, the amount of SOM research done in OM research has still only been minimal. This contradiction calls for an in-depth study of the state of affairs of SOM research, and we have conducted just such a study in 10 of the most relevant and representative outlets in the OM field, as well as in pipeline research (Proceedings of the POMS, DSI and EurOMA Conferences). Our results aim to provide answers to the following questions, amongst others: (1) Is greater importance now attached to SOM research within OM research? (2) What are the main topics of research? Are they the same topics that have been proposed in SOM research agendas? (3) What methods are used in SOM research? (4) What are the most commonly studied sectors of economic activities? (5) Are there any differences from OM research in terms of content and methods? Some of our findings show that although a growth in SOM research had been predicted in earlier studies, there is still only a minimal amount done (7.5% of OM research); seven topics command 61.5% of SOM research, which (with some exceptions) is consistent with SOM research agendas; there is more research done on strategic issues than on tactical/operational issues; models and simulations are still more common than empirical research, but trends point to a shift to the latter; the majority of research focuses on a specific sector, and three sectors account for 50% of the total; there is a clear connection between type of journal and type of research, research method and sector of activity. #

a b s t r a c tLiterature on healthcare supply chain management has shown that the kanban system can provide significant benefits. However, very few benefits have been empirically demonstrated and the extent of each remains unknown. This study aims to measure nurses' satisfaction with kanban systems in logistics of medical consumables and assesses possible advantages and differences among user groups through an anonymous survey at Hospital Universitario Virgen Macarena of Seville, Spain. Treatment of responses included an exploratory factor analysis, and a CAPTCA analysis. The results showed a high level of satisfaction for each aspect of the kanban system. Moreover, it highlighted the differences of opinion between groups of individuals according to workplace, nursing units, job category, seniority, age and kanban training. The exploratory factor analysis revealed that two factors underlie the collected assessments: the inherent advantages of a kanban system, and the logistics system performance as a whole. Thus, hospital managers should promote the implementation of kanban systems, since it increases nurses' satisfaction and provides significant benefits. Implantación del sistema Kanban en Hospitales: evaluación de la satisfacción de enfermeríaCódigos JEL: I1 M11Palabras clave: Salud Kanban Sistema de doble cajón Enfermería Logística Hospitalaria r e s u m e n La literatura sobre cadena de suministro en sanidad ha mostrado que el sistema kanban puede proporcionar importantes ventajas a las organizaciones sanitarias. Sin embargo, muy pocas de ellas se han demostrado y valorado empíricamente. Este trabajo tiene como objetivo medir la satisfacción de la enfermería con el sistema kanban, valorar cada una de sus posibles ventajas e identificar posibles diferencias entre diferentes grupos de usuarios. El trabajo ha consistido en realizar una encuesta anónima en el Hospital Universitario Virgen Macarena de Sevilla, España. El tratamiento de las respuestas incluye un análisis factorial exploratorio y un análisis CAPTCA. Los resultados muestran un alto nivel de satisfacción con cada aspecto del sistema kanban y la existencia de diferencias entre individuos según centro de trabajo, unidad de enfermería, categoría laboral, antigüedad, edad y formación en kanban. El análisis factorial exploratorio señala la existencia de dos factores subyacentes a las valoraciones recogidas: las ventajas inherentes del sistema kanban y el rendimiento del sistema logístico en su conjunto. Como conclusión, los directivos hospitalarios deberían promover la implantación de sistemas kanban ya que ello incrementa la satisfacción de enfermería y proporciona importantes beneficios.
