New intelligent network approach for monitoring physiological parameters : the case of Benin

Benin health system is facing many challenges as: (i) affordable high-quality health care to a growing population providing need, (ii) patients’ hospitalization time reduction, (iii) and presence time of the nursing staff optimization. Such challenges can be solved by remote monitoring of patients. To achieve this, five steps were followed. 1) Identification of the Wireless Body Area Network (WBAN) systems’ characteristics and the patient physiological parameters’ monitoring. 2) The national Integrated Patient Monitoring Network (RIMP) architecture modeling in a cloud of Technocenters. 3) Cross-analysis between the characteristics and the functional requirements identified. 4) Each Technocenter’s functionality simulation through: a) the design approach choice inspired by the life cycle of V systems; b) functional modeling through SysML Language; c) the communication technology and different architectures of sensor networks choice studying. 5) An estimate of the material resources of the national RIMP according to physiological parameters. A National Integrated Network for Patient Monitoring (RNIMP) remotely, ambulatory or not, was designed for Beninese health system. The implementation of the RNIMP will contribute to improve patients’ care in Benin. The proposed network is supported by a repository that can be used for its implementation, monitoring and evaluation. It is a table of 36 characteristic elements each of which must satisfy 5 requirements relating to: medical application, design factors, safety, performance indicators and materiovigilance

Internet des objets pour l’amelioration des soins de sante au Benin

L’essor des nouvelles technologies en micro-électroniques, en télécommunication et en réseaux, a entraîné l’apparition de nouveaux outils et objets de communication. La croissance sans cesse de la population mondiale induit des questions sur l’efficacité et la sécurité de la prise en charge des patients. Cette problématique est effective au Bénin au regard du ratio personnel soignant(PS) pour 10000 habitants qui est de 4.555 soit moins de 1/5 de la norme OMS qui est 25 PS pour 10000 habitants. Ces données nous amènent à concevoir une solution technologique de télésurveillance à base d’objets connectés pouvant contribuer à assurer les soins de qualité sécurisés aux patients du système sanitaire Béninois. Pour y parvenir, il est procédé à l’analyse des besoins du système par la démarche du cycle de vie des systèmes selon le model en V. Ensuite, la logique fonctionnelle du système à concevoir a été établie. Ceci, sur les bases des fonctionnalités grâce au système de modélisation SysML. Les choix technologiques et du réseau de communication ont été faits sur la base des capteurs qui seront répartis sur le patient et dans son environnement pour mesurer ses paramètres. Ce travail a permis de concevoir l’hôpital intelligent. Mots clés : architecture, GPS, GSM, hôpital, objets connectés, patient, WBAN. English abstract: Internet of things for improving health care in Benin Expansion of the new technologies in microelectronics, in telecommunications, in networks, has led to the appearance of new tools and objects of communication. The growth ceaselessly of the world population leads questions on the efficiency and the safety of the management of patients. This problem is already effective in Benin about the caregiver ratio per 10000 inhabitants, which is 4.555, less than 1/5 of the WHO standard which is 25 caregivers per 10000 inhabitants. These data lead us to anticipate the proposal of a technological solution that can contribute to ensuring quality and safe care for patients in the Benin health system. To achieve that, we proceeded to the analysis of the needs for the system by the approach of the life cycle of the systems according to the model V. Then, the functional logic of the system to be conceived was established on the basis of the features, thanks to the system of modelling SysML. The technological choices of the communication network were made on the basis of the sensors which will be distributed on the patient’s body to measure his parameters. This work allowed to conceive the intelligent hospital. Keywords: architecture, GPS, GSM, hospital, connected objects, patient, WBAN

Medical devices in Sub-Saharan Africa : optimal assistance via a computerized maintenance management system (CMMS) in Benin

In limited resources settings, Health Technology Management (HTM) presents specific challenges, which significantly differ from those faced in higher income settings. In Sub-Saharan Africa (SSA), HTM requires holistic approaches based on reliable information on medical devices operationalized in local medical locations, which may differ significantly from the USA or European ones. Computerized Maintenance Management System (CMMS) tools offer unprecedented opportunities to optimize medical device organization and management in SSA. Nonetheless, CMMS for SSA should be designed to meet real local needs and facing local economic and organizational constraints
