GAINESVILLE, FL – Helping patients with dengue can be challenging – especially in countries with multiple diseases spread by mosquitoes. Dengue, chikungunya, and Zika are viruses spread by the same type of mosquito; all three viruses are present in Ecuador and many other countries in Latin America and the Caribbean. Patients infected with one of these viruses tend to have similar, indistinct symptoms, which can make it difficult for a clinician to determine which disease is affecting the patient and which treatment steps to take. Most critically, the clinician must determine whether the patient should be checked into the hospital for close monitoring, or if the patient can be sent home to rest and recover. Failing to hospitalize a sick patient can be a deadly mistake, but sending too many patients to be hospitalized can overwhelm health systems and increase costs to the public health sector.

New clinical prediction research through a collaboration between the Quantitative Disease Ecology and Conservation (QDEC) Lab Group at the University of Florida and SUNY—Upstate Medical University tests the ability of machine learning to predict whether these patients should be hospitalized or not, using patient information collected by the clinician. The study, Severity Index for Suspected Arbovirus (SISA): Machine learning for accurate prediction of hospitalization in subjects suspected of arboviral infection was recently published in PLoS Neglected Tropical Diseases and was completed through collaborative efforts between students and researchers at the University of Florida, SUNY – Upstate Medical University, Cornell University, and the Ecuadorian Ministry of Public Health. Patient information and laboratory test results were collected from patients recruited into an ongoing arbovirus surveillance study as well as hundreds of paper medical records that were processed using machine learning.

Machine learning is a method wherein data are used to make predictions by applying a model or series of calculations (called algorithms) to the data. There are hundreds of machine learning algorithms – some might work really well or might fail entirely to make accurate predictions for a given dataset. “Our approach is unique in that we don’t assume that one algorithm is superior – we test and compare multiple algorithms to find the one that works best for our data” says Dr. Rachel Sippy, a postdoctoral researcher with QDEC and SUNY–Upstate Medical University and lead author of the paper. “Now that we have found an algorithm that works well with these types of patient information, we can test it on new groups of patients and confirm that it works under many circumstances.”

The published research lays the groundwork for the creation of a tool that clinicians could use at the bedside. The authors envision a mobile app where the clinician enters the patient data and receives a recommendation to hospitalize the patient or send them home. “While the experience of clinicians could never be replaced with an app, these kinds of decision-support tools can provide valuable additional information that can be taken into account by the clinician who is faced with making a potentially lifesaving decision,” explains Dr. Anna Stewart Ibarra, co-author of the publication.

Predicciones de Aprendizaje Automático de Pacientes con Dengue Arrojan Resultados Prometedores

GAINESVILLE, FL – Ayudar a los pacientes con dengue puede ser un desafío – especialmente en países con múltiples enfermedades transmitidas por mosquitos. Dengue, chikungunya y zika son virus transmitidos por el mismo tipo de mosquito, los tres virus están presentes en el Ecuador y en muchos otros países de América Latina y el Caribe. Pacientes infectados con uno de estos virus tienden a tener síntomas similares, indistintos lo cual puede dificultar al médico a determinar cuál enfermedad está afectando al paciente y qué pasos de tratamiento debe tomar. Lo más crítico es que el médico debe determinar si el paciente debería ser ingresado en el hospital para un monitoreo más cercano o si el paciente puede ser enviado a casa para descansar y recuperarse. No hospitalizar a un paciente enfermo puede ser un error mortal, pero enviar muchos pacientes a ser hospitalizados puede abrumar los sistemas de salud e incrementar los costos al sector de salud pública.

Una nueva investigación de predicción clínica a través de una colaboración entre el Quantitative Disease Ecology and Conservation (QDEC) Lab Group de la Universidad de Florida y la Universidad Médica de SUNY Upstate, prueba la capacidad del aprendizaje automático para predecir si estos pacientes deberían ser hospitalizados o no, utilizando la información del paciente recogido por el médico. El estudio, Severity Index for Suspected Arbovirus (SISA): Machine learning for accurate prediction of hospitalization in subjects suspected of arboviral infection, se publicó recientemente en PLoS Neglected Tropical Diseases y se completó mediante esfuerzos de colaboración entre estudiantes e investigadores de la Universidad de Florida, SUNY – Upstate, Universidad de Cornell y el Ministerio de Salud Pública de Ecuador. La información del paciente y los resultados de las pruebas de laboratorio se obtuvieron de los pacientes reclutados en un estudio de vigilancia de arbovirus en curso, así como también de cientos de registros médicos en papel que se procesaron mediante el aprendizaje automático.

El aprendizaje automático es un método donde los datos son usados para hacer predicciones aplicando un modelo o series de cálculos (llamados algoritmos) a los datos. Existen cientos de algoritmos de aprendizaje automático – algunos pueden funcionar realmente o pueden fallar por completo para hacer predicciones precisas para un conjunto de datos dados. “Nuestro enfoque es único en el sentido de que nosotros no asumimos que un algoritmo es superior – probamos y comparamos múltiples algoritmos para encontrar el que mejor funcione para nuestros datos” dice Dra. Rachel Sippy, una investigadora posdoctoral con QDEC y SUNY-Upstate y autora principal de la publicación. “Ahora que hemos encontrado un algoritmo que funciona bien con este tipo de información del paciente, podemos probarlo en nuevos grupos de pacientes y confirmar que funciona bajo muchas circunstancias.”

La investigación publicada sienta las bases para la creación de una herramienta que los médicos podrían usar como cabecera. Los autores visualizan una aplicación en teléfono donde los médicos ingresen los datos de los pacientes y reciban una recomendación para hospitalizar al paciente o enviarlos a casa. “Mientras la experiencia de los médicos podría nunca ser reemplazada con la aplicación, este tipo de herramientas de apoyo a la toma de decisiones puede proporcionar información adicional valiosa que puede tener en cuenta el médico quien se enfrenta a tomar una decisión potencialmente vital”, explica la Dra. Anna Stewart Ibarra, coautora de la publicación.

GAINESVILLE, FL – Fighting mosquito-borne disease can be costly – in both health and financial resources. While mosquito control is an effective way to combat the spread of diseases like dengue fever, the cost of spraying every house in a city quickly adds up. These costs limit public health vector control programs, which often operate on limited annual budgets.

The team of UF researchers used methods from transportation geography to model the most efficient driving routes from Ministry of Health mosquito control centers (black squares) to neighborhoods throughout the city of Machala, Ecuador.
El equipo de investigadores de la Universidad de Florida usó métodos de transportación geográfica para hacer una maqueta de las rutas más eficientes del Ministerio de Salud Pública de los centros del control del zancudo (cuadrados negros) hacia vecindarios en la ciudad de Machala, Ecuador.

New geospatial science research from the Quantitative Disease Ecology and Conservation (QDEC) Lab Group at the University of Florida aims to improve the efficiency of mosquito control programs by borrowing methods from transportation geography to solve medical geography problems – optimizing routes using road network analysis. The study, “A network analysis framework to improve the delivery of mosquito abatement services in Machala, Ecuador”, recently published in the International Journal of Health Geographics, was conducted in the city of Machala, Ecuador in collaboration with the Ecuadorian Ministry of Health. Locations with potentially higher risk of mosquito-borne disease activity were identified, and the researchers created models of the best delivery routes from ministry-operated mosquito control facilities and every neighborhood in Machala.

In addition to identifying the most efficient driving routes, the team also determined which control facility locations were ideal under different management priorities. Public health workers typically spray for mosquitoes in response to incoming disease cases reported to the health department. Instead, some neighborhoods could be targeted ahead of outbreaks based on environmental risk factors. Moving control facilities closer to at-risk neighborhoods translates into monetary savings. “Health ministry priorities and strategies may change over time,” says Cat Lippi, a PhD student in QDEC and lead author on the paper. “This work provides a new way for health officials to compare the delivery cost of different management strategies when developing their control programs.”

These models can be used to improve public vector control services and reduce operating costs. “The results of this study have implications beyond Ecuador – and beyond dengue,” says senior author Dr. Sadie Ryan, the principal investigator for QDEC. “The framework we present can be used by any agency that plans for intervention through mosquito control operators.”

Nuevo Enfoque a través de la Red para la Distribución del Control del Zancudo rinde ideas en una Ciudad del Sur del Ecuador

GAINESVILLE, FL – Pelear contra enfermedades causadas por el zancudo puede ser costoso. Aún cuando el control del zancudo es una manera efectiva de combatir la propagación de enfermedades como la fiebre del dengue, el precio de fumigar cada casa en una ciudad aumenta las cifras de costo rápidamente. Estos costos limitan programas del control del vector para la salud pública, el mismo que opera con presupuestos muy limitados.

Investigaciones nuevas de ciencias geoespaciales de el Quantitative Disease Ecology and Conservation (QDEC) Lab Group de la Universidad de Florida tienen como objetivo mejorar la eficiencia de programas para el control del zancudo al métodos de la transportación geográfica para resolver problemas médicos basados en la geografía, optimizando rutas de análisis de la red. El estudio “A network analysis framework to improve the delivery of mosquito abatement services in Machala, Ecuador”, recientemente publicado en la Revista Internacional de la Geografía de la Salud, se llevó a cabo en la ciudad de Machala, Ecuador en colaboración con el Ministerio de Salud Pública del Ecuador. Se identificaron lugares con más potenciales de actividad de riesgo para la transmición de enfermedades causadas por zancudos, y los investigadores crearon modelos de las rutas de más eficacia, manejados por el ministerio, en el entrego de los servicios para el control del zancudo y todos los vecindarios de Machala

A más de identificar las rutas de entrega más eficientes, el equipo también determinó cuáles ubicaciones de servicio de control fueron las más ideales bajo diferentes prioridades de adminis

tración. Los trabajadores de salud pública típicamente fumigan para zancudos respondiendo a casos de enfermedades reportados al departamento de salud. En vez, algunos vecindarios podrían ser asistidos antes de un brote basado en riesgos del ambiente. El mover servicios de control más cerca a los vecindarios en riesgo se traduce como ahorros monetarios. “Las prioridades y estrategias del ministerio de salud pueden cambiar al pasar del tiempo,” dice Cat Lippi, estudiante de PhD en QDEC y autora que encabeza este estudio. “Este trabajo de investigación provee una nueva pauta para dirigentes de la salud para comparar el costo de entrega de diferentes estrategias de administración cuando desarrollan sus programas de control.”

Estos modelos pueden ser usados para mejorar servicios de control del vector y reducir costos de operación. “Los resultados de este estudio tienen implicaciones más allá del Ecuador – y más allá del dengue,” dice la autora mayor Dra. Sadie Ryan, la investigadora principal de QDEC. “El armazón que presentamos puede ser utilizado por cualquier agencia que planea la intervención a través de operadores de control del zancudo.”

Focus Areas

Research Statement:

My research interests surround precipitation variability – in particular in its extremes (drought, floods), as well as climate dynamics, and climate adaptation. My other joys are in mentoring undergraduate research, supporting stakeholder science through assisting with climate data interpretation, and assisting in a recent early-career workshop facilitated by CS-CASC. I had the privilege of co-authoring the Southern Great Plains Chapter of the National Climate Assessment (NCA4). At the University of Florida, I will be expanding the meteorological teaching and research within the department of Geography. I will also continue to work with colleagues at OU on the PRES2iP project, which aims to improve our understanding and prediction of heavy precipitation at seasonal to sub-seasonal lead times.
