The purpose of this paper is to explore the current state of logistics practices in healthcare organizations in Bogota, Colombia.

The assessment is based on case study research using open interviews, focused interviews, a questionnaire and direct observations as sources of evidence. Seven Colombian health care settings are analyzed: four public hospitals and three private clinics. Cross-case analysis allows the identification of patterns regarding supply management, inventory management, replenishment and use of information and communication technologies.

Manual procedures, poor planning, little recognition from top management and a lack of specialized personnel characterize the current situation. Innovative practices with a potential to improve the efficacy of logistics activities are rare, particularly in public hospitals.

Future research could replicate this study in other Colombian cities, in order to generalize the results to the whole country. It could also be interesting to document successful and less successful implementations of innovative logistics practices in Colombian hospitals to guide and promote their adoption.

The small number of cases considered, and the fact that the research is concentrated in one city, limits the generalizability of the results.

To the best of the authors’ knowledge, this research is the first to explore the state of healthcare logistics practices in Colombia.

Este artículo explora el estado actual de las prácticas logísticas en los hospitales de Bogotá, Colombia.

La evaluación se basa en la investigación de un estudio de caso utilizando entrevistas abiertas, entrevistas centradas, un cuestionario y observaciones directas como fuentes de evidencia. Se analizan siete establecimientos de salud colombianos: cuatro hospitales públicos y tres clínicas privadas. El análisis cruzado de casos permite la identificación de patrones relacionados con la gestión del abastecimiento, la gestión de inventarios, la reposición y el uso de las tecnologías de la información y la comunicación (TIC).

Los procedimientos manuales, la mala planificación, el escaso reconocimiento de la alta dirección y la falta de personal especializado caracterizan la situación actual. Las prácticas innovadoras con un potencial para mejorar la eficacia de las actividades logísticas son raras, particularmente en los hospitales públicos.

Este estudio se podría replicar en otras ciudades colombianas, con el fin de generalizar los resultados a todo el país. También podría ser interesante documentar implementaciones exitosas y menos exitosas de prácticas logísticas innovadoras en hospitales colombianos para guiar y promover su adopción.

El pequeño número de casos considerados, y el hecho de que la investigación se concentra en una ciudad, limita la generalización de nuestros resultados.

Según nuestro conocimiento, esta investigación es la primera en explorar el estado de las prácticas de logística hospitalaria en Colombia.

To solve the problem, a mathematical model is proposed; it relies on a directed acyclic graph (DAG), in which arcs are used to indicate whether a pair of appointments can be assigned to the same route or not (and so to the same care worker). The proposed model aims at minimizing the personnel required to meet daily demand and balancing workloads among the workers while considering the varying traffic patterns derived from traffic congestion.

This paper aims at providing solution approaches for addressing the problem of assigning care workers to deliver home health-care (HHC) services, demanding different skills each. First, a capacity planning problem is considered, where it is necessary to define the number of workers required to satisfy patients' requests and then, patients are assigned to the care workers along with the sequence followed to visit them, thus solving a scheduling problem. The benefits obtained by permitting patients to propose multiple time slots where they can be served are also explored.

The results indicate that the problem can be efficiently solved for medium-sized instances, that is, up to 100 daily patient requests. It is also indicated that asking patients to propose several moments when they can receive services helps to minimize the need for care workers through more efficient route allocations without affecting significantly the balance of the workloads.

This article provides a new framework for modeling and solving a HHC routing problem with multiskilled personnel. The proposed model can be used to identify efficient daily plans and can handle realistic characteristics such as time-dependent travel times or be extended to other real-life applications such as maintenance scheduling problems.
