A model to develop frailty diagnosis tools through mobile devices and a service-oriented approach

  1. 1. A model to develop frailty diagnosistools through mobile devices and a service-oriented approach J. Fontecha, R. Hervás, J. Bravo, F.J. Navarro MAmI Research Lab Geriatric Services Castilla-La Mancha University Residencia Asistida de Ancianos Ciudad Real, Spain Ciudad Real, Spain
  2. 2. What is Frailty? • Woodhouse, 1988 “elderly people more than 65 years old who depend on other people to perform their basic needs”. • Gillick, 1989 “old debilitated individuals who cannot survive without substantial help from others”.What is Frailty? 1 2 3Assessment methods Decrease resistanceNew Technologies Impact Cumulative Adverse health and physiologicalThe proposed model wear effects Conceptual Design reserves Functional Design 2Conclusions & Discussions
  3. 3. Assessment methods 1. Global scores from standardized questionnaires filled by physicians. Barthel Index Tinnetti MMS Lawton&Brody … 2. Overview of the elder and his environment. 3. Measures from medical instruments. Dynamometer Scale Blood pressure meter …What is Frailty?Assessment methodsNew Technologies Impact 4. Analysis of lab reports from the elderly patient.The proposed model Conceptual Design Functional Design 3Conclusions & Discussions
  4. 4. New technologies impact • New technologies for Frailty diagnosis BMI Total water ADL level Age Lean mass Need help Drug number Tinetti balance score Weight Fat mass Tinetti gait score Size Leukocytes Depression Blood iron Barthel index Gender Ferritin Vitamin B12 MMS Total protein Malnutrition CRP Calcium Polypharmacy Centralized Assessment Combination with accelerometer results* Standard deviationWhat is Frailty? Arithmetic meanAssessment methods Pearson’s coefficient of variationNew Technologies Impact Amplitude Absolute mean difference VarianceThe proposed model Acceleration mean Conceptual Design Functional Design * Elderly Frailty detection by using accelerometer-enabled smartphones and clinical information records. 4Conclusions & Discussions Jesús Fontecha, Fco.

  5. 5. The proposed model • Goal: “Facilitating the implementation of automated systems to be run on mobile devices in order to get a centralized & objective frailty assessment”. • Consideration: The technology used to implement our model depends on developers Two Parts Which? Conceptual Functional How?What is Frailty? (structure) Design Design (functionality)Assessment methodsNew Technologies ImpactThe proposed model Conceptual Design Entities Roles Services Functionalities Functional Design 5Conclusions & Discussions
  6. 6. Conceptual Design (I) • Identification of entities and roles -Service deployment Mobile Phone - Interaction & Visualization - Accelerometer data acquisiton Devices Accelerometer - Accelerometer data acquisiton Server - Providing services to mobile device - Process deployment - Providing the patient record PatientWhat is Frailty? - Carrying the accelerometer to the waistAssessment methods UsersNew Technologies ImpactThe proposed model Physician - Interacting with mobile device Conceptual Design - Making a final diagnosis Functional Design 6Conclusions & Discussions
  7. 7. Conceptual Design (II) • Identification of entities and roles Questionnaires - Measures fromclinical indicators Artifacts Medical -Measures from clinical equipment Instruments Patient Record - Values of frailty risk factors Patient Stack - Frailty data storage Procedures & Acquisition - Getting data from entitiesWhat is Frailty? Services Processing - Analyisis and processing dataAssessment methodsNew Technologies ImpactThe proposed model Storage - Data storage Conceptual Design Functional Design Result - Providing final results on mobile device 7Conclusions & Discussions
  8. 8. Conceptual Design (III)What is Frailty?Assessment methodsNew Technologies ImpactThe proposed model Conceptual Design Functional Design 8Conclusions & Discussions
  9. 9. Functional Design (I) • Service-Oriented Approach  Procedures & Services • Requirements and Functions SERVICES Mobile Web - Accelerometer data acquisition - Patient record extraction - Accelerometer data processing - Comparison and analysis procedureWhat is Frailty? - Visualization of frailty assessment - Setting up a built resultAssessment methods - Storage into patient stackNew Technologies ImpactThe proposed model Conceptual Design Functional Design 9Conclusions & Discussions
  10. 10. Functional Design (II) • Inputs and Outputs Service Type Inputs Outputs Accelerometer data Mobile Accelerometer signal Accelerometer acquisition values (x,y,z) Accelerometer data Mobile Accelerometer Accelerometry processing values (x,y,z) indicators Patient record Web Patient record, Frailty risk factors extraction accelerometry indicators Analysis procedure Web Frailty risk factors, Frailty assessment patient stack Setting up a built result Web Frailty assessment Frailty assessment formalizedWhat is Frailty? Visualization of frailty Mobile Frailty assessment Information, tips &Assessment methods assessment formalized chartsNew Technologies Impact Storage into patient Web Risk factors from the Patient stack withThe proposed model stack new patient new patient Conceptual Design Functional Design 10Conclusions & Discussions
  11. 11. Conclusion and Discussion • Model to support frailty diagnosis in a ubiquitous environment • A centralized system valid for physicians • Mobile devices (mobile phones) as the core of these systems • Providing a conceptual and functional framework. • Evaluation of efficiency & usability: Entities and Services • Comparison • Frailty tools based on our model vs. otherWhat is Frailty?Assessment methodsNew Technologies ImpactThe proposed model Conceptual Design Functional Design 11Conclusions & Discussions
