- ItemOpen AccessA Free App for Diagnosing Burnout (BurnOut App): Development Study(JMIR Publications, 2022) Gòdia Manonelles, Jordi; Pifarré Montalà, Marc; Vilaplana Mayoral, Jordi; Solsona Tehàs, Francesc; Abella i Pons, Francesc; Calvo, Antoni; Mitjans, Anna; Gonzalez Olmedo, Maria PauBackground: Health specialists take care of us, but who takes care of them? These professionals are the most vulnerable to the increasingly common syndrome known as burnout. Burnout is a syndrome conceptualized as a result of chronic workplace stress that has not been successfully managed. Objective: This study aims to develop a useful app providing burnout self-diagnosis and tracking of burnout through a simple, intuitive, and user-friendly interface. Methods: We present the BurnOut app, an Android app developed using the Xamarin and MVVMCross platforms, which allows users to detect critical cases of psychological discomfort by implementing the Goldberg and Copenhagen Burnout Inventory tests. Results: The BurnOut app is robust, user-friendly, and efficient. The good performance of the app was demonstrated by comparing its features with those of similar apps in the literature. Conclusions: The BurnOut app is very useful for health specialists or users, in general, to detect burnout early and track its evolution.
- ItemOpen AccessA Machine-Learning Model for Lung Age Forecasting by Analyzing Exhalations(MDPI, 2022) Pifarré Montalà, Marc; Tena del Pozo, Alberto; Clarià Sancho, Francisco; Solsona Tehàs, Francesc; Vilaplana Mayoral, Jordi; Benavides, Arnau; Mas, Lluis; Abella i Pons, FrancescSpirometers are important devices for following up patients with respiratory diseases. These are mainly located only at hospitals, with all the disadvantages that this can entail. This limits their use and consequently, the supervision of patients. Research efforts focus on providing digital alternatives to spirometers. Although less accurate, the authors claim they are cheaper and usable by many more people worldwide at any given time and place. In order to further popularize the use of spirometers even more, we are interested in also providing user-friendly lung-capacity metrics instead of the traditional-spirometry ones. The main objective, which is also the main contribution of this research, is to obtain a person’s lung age by analyzing the properties of their exhalation by means of a machine-learning method. To perform this study, 188 samples of blowing sounds were used. These were taken from 91 males (48.4%) and 97 females (51.6%) aged between 17 and 67. A total of 42 spirometer and frequency-like features, including gender, were used. Traditional machine-learning algorithms used in voice recognition applied to the most significant features were used. We found that the best classification algorithm was the Quadratic Linear Discriminant algorithm when no distinction was made between gender. By splitting the corpus into age groups of 5 consecutive years, accuracy, sensitivity and specificity of, respectively, 94.69%, 94.45% and 99.45% were found. Features in the audio of users’ expiration that allowed them to be classified by their corresponding lung age group of 5 years were successfully detected. Our methodology can become a reliable tool for use with mobile devices to detect lung abnormalities or diseases.
- ItemRestrictedA queuing theory model for cloud computing(Springer Verlag, 2014-04) Vilaplana Mayoral, Jordi; Solsona Tehàs, Francesc; Teixidó Torrelles, Ivan; Mateo Fornés, Jordi; Abella i Pons, Francesc; Rius Torrentó, Josep MariaThe ability to deliver guaranteed QoS (Quality of Service) is crucial for the commercial success of cloud platforms. This paper presents a model based on queuing theory to study computer service QoS in cloud computing. Cloud platforms are modeled with an open Jackson network that can be used to determine and measure the QoS guarantees the cloud can offer regarding the response time. The analysis can be performed according to different parameters, such as the arrival rate of customer services and the number and service rate of processing servers, among others. Detailed results for the model are presented. When scaling the system and depending on the types of bottleneck in the system, we show how our model can provide us with the best option to guarantee QoS. The results obtained confirm the usefulness of the model presented for designing real cloud computing systems.
- ItemRestrictedS-PC: An e-treatment application for management of smoke-quitting patients(Elsevier, 2014) Vilaplana Mayoral, Jordi; Solsona Tehàs, Francesc; Abella i Pons, Francesc; Cuadrado, Josep; Alves, Rui; Mateo Fornés, JordiThe main objective ofthis paper is to present a new program thatfacilitates the management of people who want to quit smoking, implemented through an e-treatment software called S-PC (Smoker Patient Control). S-PC is a web-based application that manages groups of patients, provides a bidirectional communication through mobile text messages and e-mails between patients and clinicians and offers advice and control to keep track of the patients and their status. A total of 229 patients were enrolled in the study, randomly divided into two groups, although some variables were tested to ensure that there were no significant differences between the groups that could have an impact on the outcome of the treatment. There were no significant differences between the two groups regarding the ratio/number of males/females, tobacco dependence, co-oximetry, average cigarette consumption, current age and age when smoking started. The first group was made up of 104 patients (45.4% of the total) and followed a treatment that incorporated the S-PC tool, while the second one had 125 patients without the S-PC tool. S-PC was evaluated for its effectiveness at assisting the patients to give up smoking, and its effect on clinician time management. 74% of the S-PC group completed the treatment without relapses and remained abstinent three months after the completion of the treatment, understanding abstinence as being continuous (with no relapses allowed and co-oximetry below 1 ppm) from the day of stopping. In contrast only 45.6% of the No S-PC group completed the treatment without relapses and remained abstinent three months after completion of the treatment. The rate of admittance to the program has doubled in one year and patients went from having to wait for 3 months to be immediately admitted into the program.
- ItemOpen AccessSeguimiento y control de pacientes fumadores en proceso de deshabituación mediante SMS. Una experiencia en e-salud(Asociación Española de Estudios en Drogodependencias, 2014) Abella i Pons, Francesc; Vilarasau, Assumpció; Cuadrado, Josep; Solsona Tehàs, Francesc; Alves, Rui; Vilaplana Mayoral, Jordi; Serra, JoanEl consumo de tabaco continúa siendo una importante causa de morbilidad y mortalidad. El proceso terapéutico para abandonar el tabaco consiste en la desintoxicación física de la nicotina y en el mantenimiento de la abstinencia de su consumo. Nuestro estudio se sitúa en este contexto, ofreciendo una estrategia de apoyo por SMS y monitorizando al paciente a lo largo del tratamiento. Material y método. Este estudio longitudinal compara dos grupos de pacientes: uno con apoyo a través de SMS y otro, de control, que no disfruta de dicho apoyo. Los pacientes recibieron aleatoriamente mensajes de apoyo y refuerzo positivo, así como preguntas sobre su estado. El resto de la terapia es igual para ambos grupos. Resultados. El grupo que recibía apoyo por SMS presentó unas tasas de abstinencia mejores que el otro (57,1% frente a 42,9%). Los mismos participantes valoran positivamente la metodología y admiten que les ahorra tiempo y viajes. Conclusión. El uso de las TIC para monitorizar y reforzar el proceso de desintoxicación del consumo de tabaco parece ser efectivo y bien acogido por los pacientes.
- ItemOpen AccessTControl: A mobile app to follow up tobacco-quitting patients(Elsevier, 2017-04) Pifarré Montalà, Marc; Carrera Peruga, Adrián; Vilaplana Mayoral, Jordi; Cuadrado, Josep; Solsona, Sara; Abella i Pons, Francesc; Solsona Tehàs, Francesc; Alves, RuiBackground and Objective Tobacco smoking is a major risk factor for a wide range of respiratory and circulatory diseases in active and passive smokers. Well-designed campaigns are raising awareness to the problem and an increasing number of smokers seeks medical assistance to quit their habit. In this context, there is the need to develop mHealth Apps that assist and manage large smoke quitting programs in efficient and economic ways. Objectives Our main objective is to develop an efficient and free mHealth app that facilitates the management of, and assistance to, people who want to quit smoking. As secondary objectives, our research also aims at estimating the economic effect of deploying that App in the public health system. Methods Using JAVA and XML we develop and deploy a new free mHealth App for Android, called TControl (Tobacco-quitting Control). We deploy the App at the Tobacco Unit of the Santa Maria Hospital in Lleida and determine its stability by following the crashes of the App. We also use a survey to test usability of the app and differences in aptitude for using the App in a sample of 31 patients. Finally, we use mathematical models to estimate the economic effect of deploying TControl in the Catalan public health system. Results TControl keeps track of the smoke-quitting users, tracking their status, interpreting it, and offering advice and psychological support messages. The App also provides a bidirectional communication channel between patients and clinicians via mobile text messages. Additionally, registered patients have the option to interchange experiences with each other by chat. The App was found to be stable and to have high performances during startup and message sending. Our results suggest that age and gender have no statistically significant effect on patient aptitude for using TControl. Finally, we estimate that TControl could reduce costs for the Catalan public health system (CPHS) by up to € 400M in 10 years. Conclusions TControl is a stable and well behaved App, typically operating near optimal performance. It can be used independent of age and gender, and its wide implementation could decrease costs for the public health system.
- ItemOpen AccessThe cloud paradigm applied to e-Health(BioMed Central, 2013) Vilaplana Mayoral, Jordi; Solsona Tehàs, Francesc; Abella i Pons, Francesc; Filgueira, Rosa; Rius Torrentó, Josep MariaBackground: Cloud computing is a new paradigm that is changing how enterprises, institutions and people understand, perceive and use current software systems. With this paradigm, the organizations have no need to maintain their own servers, nor host their own software. Instead, everything is moved to the cloud and provided on demand, saving energy, physical space and technical staff. Cloud-based system architectures provide many advantages in terms of scalability, maintainability and massive data processing. Methods: We present the design of an e-health cloud system, modelled by an M/M/m queue with QoS capabilities, i.e. maximum waiting time of requests. Results: Detailed results for the model formed by a Jackson network of two M/M/m queues from the queueing theory perspective are presented. These results show a significant performance improvement when the number of servers increases. Conclusions: Platform scalability becomes a critical issue since we aim to provide the system with high Quality of Service (QoS). In this paper we define an architecture capable of adapting itself to different diseases and growing numbers of patients. This platform could be applied to the medical field to greatly enhance the results of those therapies that have an important psychological component, such as addictions and chronic diseases.
- ItemOpen AccessValor social de los medicamentos para dejar de fumar. Opiniones respecto a su financiación(Asociación Española de Estudio en Drogodependencias (AESED), 2020) Abella i Pons, Francesc; Gil Rodríguez, Juan; Pedra Pagés, GerardLas medidas de la OMS para controlar el tabaquismo han disminuido su prevalencia, pero aumentando las diferencias entre grupos sociales. Facilitar el acceso a los medicamentos, para dejar de fumar, a los desfavorecidos disminuye la prevalencia sin aumentar diferencias. Recientemente se ha aprobado la financiación de vareniclina y bupropion pero esa medida es susceptible de ser eliminada (ya ha ocurrido con otros medicamentos) o ampliada a la TSN y bupropion. OBJETIVO: 1) Conocer el uso del tabaco según el estatus socioeconómico. 2) Conocer la opinión de la población respecto a la financiación según el estatus socioeconómico y uso del tabaco. METODO: Estudio descriptivo poblacional. RESULTADOS: Aumenta el consumo de tabaco al disminuir el estatus. El 64,3% está a favor de la financiación. Exceptuando a los individuos sin estudios, disminuye la opinión favorable al aumentar el nivel académico. Aumenta dicha opinión al aumentar la relación con el tabaco, mínima en los no fumadores (52,6%) y máxima en fumadores diarios (79,8%). DISCUSIÓN: El resultado coincide con otros estudios, pero no con las consideraciones de un informe de 2011 de la Agencia de Evaluación de las Tecnologías Sanitarias. La no coincidencia pudiera ser una evolución de la opinión de la población, que pasa de acentuar el problema en la responsabilidad del consumidor a considerar una etiología más compleja que no solo depende del individuo. Dado el gran apoyo a la medida, ésta no debería depender, en el futuro, de situaciones políticas o económicas y debería ampliarse a TSN y bupropion.
