Fuzzy Bi-Objective Preventive Health Care Network DesignGurdal Ertek
Preventive healthcare is unlike healthcare for a cute ailments, as people are less alert to their unknown medical problems.In order to motivate public and to attain desired participation levels for preventive programs,the attractiveness of the healthcare facility is a major concern.Health economics literature indicates that attractiveness to a facility is significantly influenced by proximity of the clients to it.Hence attractiveness is generally modeled as a function of distance.However, abundant empirical evidence suggests that other qualitative factors such as perceived quality, attractions nearby, amenities, etc. also influence attractiveness. Therefore, are alistic measures hould in corporate the vagueness in the concept of attractiveness to the model.The public policymakers should also maintain the equity among various neighborhoods, which should be considered as a second objective.Finally, even though general tendency in the literature is to focus on health benefits,the cost effectiveness is still a factor that should be considered.In this paper,a fuzzy bi-objective model with budget constraints of the problem is developed.Later,by modelling the attractiveness by means of fuzzy triangular numbers and treating the budget constraint as a soft constraint, a modified (and more realistic)version of the model is introduced. Two solution methodologies, namely fuzzy goal programming and fuzzy chance constrained optimization are proposed as solutions.Both the original and the modified models are solved within the framework of a case study in Istanbul,Turkey.In the case study,the Microsoft Bing Map is utilized in order to determine more accurate distance measures among the nodes.

Nosocomial infections, also known as healthcare-associated infections (HAIs), pose a significant problem in healthcare facilities. Exchanging patient data between clinicians and public health agencies could help address the spread of HAIs. Empirical data mapping patient movement networks and monitoring HAI spread could improve understanding and response. Standardized HAI surveillance data collected annually from healthcare facilities is considered open access and can be used by researchers and health organizations without ethical restrictions to advance public health goals like HAI prevention.

The document discusses increasing value in healthcare systems through a "Triple Value Healthcare" approach. It proposes focusing on personal value for individuals, population value for given populations, and technical value through optimizing outcomes and resource use. Key strategies include providing full information to patients, shifting resources from overused to underused areas, developing population-based systems and networks, and creating a culture of stewardship. The goal is to improve outcomes while making the best use of limited resources.
This document discusses lessons that can be learned from international healthcare systems to develop a sustainable healthcare system. It provides 3 key lessons:
1. Prioritize health in policymaking by demonstrating how health impacts productivity, education, employment and economic growth.
2. Increase investment in healthcare through dedicated funding and by legislating specific access entitlements.
3. Engage patients by making services patient-centered, ensuring quality communication of information, and driving continuous quality improvement.
This quality improvement project aimed to enhance clinical data sharing between an emergency department and community health center treating homeless patients. An assessment found the organizations currently shared some electronic health data but the health center lacked access to patient summary data from the hospital. A clinical data integration plan was then developed to modify their electronic medical record systems and improve access to accurate medical information across sites of care for homeless individuals.

Electronic medical records, also known as EHRs, systematically collect electronic health information about individual patients and populations. EHRs can include demographics, medical history, medications, allergies, lab reports, and billing information. EHRs offer potential for quicker access to relevant patient information, regular updates, storage of data in multimedia formats, and increased efficiency in healthcare delivery and decision-making. Both providers and patients can benefit from EHRs, as providers can exchange information through networks and patients can access their records across locations. However, some physicians worry that patient access to notes may increase patient worry, though studies show patients are generally satisfied with EHR access.
SPATIAL CLUSTERING AND ANALYSIS ON HEPATITIS C VIRUS INFECTIONS IN EGYPT IJDKP
Lots of studies worldwide have been carried out to check out the prevalence of Hepatitis C Virus (HCV) in human populations. Spatial data analysis and clustering detection is a vital process in HCV monitoring to discover the area of high risk and to help involved decision makers to draw hypotheses about the cause of disease. Egypt is declared as one of the countries having the highest prevalence rate of HCV worldwide. The anomaly of the HCV infection’s distribution in Egypt allowed several researches to identify the reasons that contributed to such widespread of HCV in this country. One way that can help in identification of areas with highest diseases is to give a detailed knowledge about the geographical distribution of HCV in Egypt. To achieve that goal, Data mining analytical tools integrated with GIS can help to visualize the distribution. Thus, the main propose of this paper is to present a spatial distribution of HCV in Egypt using case data obtained from the Egyptian health institute National Hepatology Tropical Medicine Research Institute (NHTMR). The visualization of the spatial analysis distribution by means of GIS allows us to investigate statistical results that are easily interpreted by non-experts.
Disease cost drivers hai apec hlm nusa dua 2013sandraduhrkopp
Healthcare-associated infections (HAIs) occur in hundreds of millions of patients each year globally, causing increased illness, death and costs. HAIs typically involve four types of infections and rates are usually higher in developing countries. HAIs prolong hospital stays by up to 3 weeks and increase costs by USD $4,888 to $11,591 per infection episode. It is estimated that 65-70% of HAIs are preventable. While preventing HAIs requires initial investment, it can free up hospital beds and resources in the long-run, improving outcomes and making more efficient use of limited healthcare funds.
This document discusses how clinical IT could help with dengue management. It notes that while IT has helped with disease surveillance, few have explored its role in clinical settings for dengue case management. The document proposes that clinical decision support systems could provide alerts, reminders, assessment templates, management tools for different dengue classifications, electronic disease reporting, and integrated clinical data to help detect epidemics earlier. However, it notes the feasibility and value of these IT roles require further implementation and evaluation.

The document discusses the use of eHealth technologies like smartphones, tablets, and web-based applications to manage schizophrenia. An expert panel saw opportunities for eHealth to improve access to care, monitor patients remotely, and increase medication adherence. However, they also noted challenges including patient suspicion of technology, costs, and a lack of research evidence and regulatory oversight for some eHealth tools. In summary, while eHealth shows promise for schizophrenia management, more research is still needed to implement technologies effectively and address barriers.
Here are some thought-provoking questions about using public health informatics and data to address community health issues:
- What public health data would have been used to determine the need for a mass inoculation program against a new strain of influenza? Data on previous flu seasons like hospitalizations and deaths, current flu activity in the population, characteristics of the new strain, and susceptibility in the community based on previous vaccination coverage could all factor into determining if a mass program is needed.
- What data will be collected to determine the success of such a program? Data that could be collected includes numbers of individuals vaccinated, demographic information on who was vaccinated, monitoring disease surveillance systems for cases and outbreaks associated with the new strain, tracking severe

Big data approaches to healthcare systemsShubham Jain
The idea behind this presentation is to explore how big data will revolutionize existing healthcare system effectively by reducing healthcare concerns such as the selection of appropriate treatment paths, quality of healthcare systems and so on. Large amount of unstructured data is available in various organizations (payers, providers, pharmaceuticals). We will discuss all the intricacies involved in massive datasets of healthcare systems and how combination of VPH technologies and big data resulted into some mind-boggling consequences. Major opportunities in healthcare includes the integration of various data pools such as clinical data, pharmaceutical R&D data and patient behaviour and sentiment data. Finding potential insights from big data with the help of medical image processing techniques, predictive modelling etc. will eventually help us to leverage the ever-increasing costs of care, help providers practice more effective medicine, empower patients and caregivers, support fitness and preventive self-care, and to dream about more personalized medicine.

Abstract
Healthcare as we know it is in the process of going through a massive change - from episodic to continuous, from disease-focused to wellness and quality of life focused, from clinic centric to anywhere a patient is, from clinician controlled to patient empowered, and from being driven by limited data to 360-degree, multimodal personal-public-population physical-cyber-social big data-driven. While the ability to create and capture data is already here, the upcoming innovations will be in converting this big data into smart data through contextual and personalized processing such that patients and clinicians can make better decisions and take timely actions for augmented personalized health. In this talk, we will discuss how use of AI techniques on semantically integrated patient-generated health data (PGHD), environmental data, clinical data, and public social data is exploited to achieve a range of augmented health management strategies that include self-monitoring, self-appraisal, self-management, intervention, and Disease Progression Tracking and Prediction. We will review examples and outcomes from a number of applications, some involving patient evaluations, including asthma in children, bariatric surgery/obesity, mental health/depression, that are part of the Kno.e.sis kHealth personalized digital health initiative.

3, 4, 5]. Reports say knowledge from the U.S. care system alone reached, in 2011, one hundred
fifty exabytes. At this rate of growth, huge knowledge for U.S. care can before long reach the
zettabyte (1021 gigabytes) scale and, shortly when, the yottabyte (1024 gigabytes) [6]. Kaiser
Permanente, the California-based health network, that has over nine million members, is
believed to possess between twenty six.5 and forty four petabytes of doubtless made knowledge
from EHRs, as well as pictures and annotations [6].
By definition, huge knowledge in care refers to electronic health knowledge sets therefore
massive and complicated that they\'re tough (or impossible) to manage with ancient computer
code and/or hardware; nor will they be simply managed with ancient or common knowledge
management tools and strategies [7]. huge knowledge in care is overwhelming not solely due to
its volume however additionally due to the range of information varieties and also the speed at
that it should be managed [7]. The totality of information associated with patient care and well-
being compose “big data” within the care business. It includes clinical knowledge from CPOE
and clinical call support systems (physician’s written notes and prescriptions, medical imaging,
laboratory, pharmacy, insurance, and alternative body knowledge); patient knowledge in
electronic patient records (EPRs); machine generated/sensor data, like from observance
important signs; social media posts, as well as Twitter feeds (so-called tweets) [8], blogs [9],
standing updates on Facebook and alternative platforms, and net pages; and fewer patient-
specific data, as well as emergency care knowledge, news feeds, and articles in medical journals.
For the massive knowledge person, there is, amongst this large quantity and array of information,
chance. By discovering associations and understanding patterns and trends inside the
information, huge knowledge analytics has the potential to enhance care, save lives and lower
prices. Thus, huge knowledge analytics applications in care cash in of the explosion in
knowledge to extract insights for creating higher enlightened selections [10, 11, 12], and as a
groundwork class square measure noted as, no surprise here, huge knowledge analytics in care
[13, 14, 15]. once huge knowledge is synthesized and an.
- The document discusses the issue of missing data values in electronic health records (EHRs), which poses a challenge for developing clinical decision support systems (CDSS) using predictive analytics.
- It introduces a new framework called "Missing Care" to address the high levels of missing values in many EHR variables (up to 70-90% missing). Missing Care aims to select the most important variables with acceptable levels of missingness.
- The document applies Missing Care to analyze a large EHR dataset to develop a CDSS for detecting Parkinson's disease, which currently affects over 1 million Americans but is often undiagnosed or misdiagnosed.
Big Data, CEP and IoT : Redefining Holistic Healthcare Information Systems an...Tauseef Naquishbandi
Healthcare industry has been a significant area for innovative application of various technologies over decades. Being an area of social relevance governmental spending on healthcare have always been on the rise over the years. Event Processing (CEP) has been in use for many years for situational awareness and response generation. Computing technologies have played an important role in improvising several aspects of healthcare. Recently emergent technology paradigms of Big Data, Internet of Things (IoT) and Complex Event Processing (CEP) have the potential not only to deal with pain areas of healthcare domain but also to redefine healthcare offerings. This paper aims to lay the groundwork for a healthcare system which builds upon integration of Big Data, CEP and IoT.

It describes some pilots that are launching this summer and fall to test querying data from various sources like public health departments and the FDA to understand population health metrics and drug safety. The document advocates that implementing distributed population queries following common standards can improve using health IT to benefit patients and populations by aggregating and analyzing vast health data in real-time.
Presentation “Harnessing EHRs and Health IT to Achieve Population Health”
Jonathan Weiner, DrPH
Professor Department of Health Policy and Management
Director of Center for Population Health IT
Johns Hopkins Bloomberg School of Public Health, Baltimore Maryland
Professor Weiner’s presentation will focus on how electronic health records and other e-health tools can be harnessed to move beyond providing medical care for a single patient episode towards the achievement of “population health.” This provocative presentation will offer new conceptual paradigms and will review “big data” opportunities and challenges. The emphasis of the talk will be on how population focused care transformation can be brought about through the integration and application of e-health/EHR systems and claims/MIS systems. The talk will offer examples of analytic tools and methods designed to increase the effectiveness, efficiency and equity of care provided at a geographic community level and to “populations” of consumers enrolled in health plans, ACOs and other integrated delivery systems.
Key goals of presentation:
∙ To offer frameworks and paradigms to better understand how EHRs and other HIT can improve population health
∙ To outline opportunities and challenges for communities, ACOs and other integrated delivery systems
∙ To offer some case studies on the application of health IT to population health

The Ultimate Guide in Setting Up Market Research System in Health-TechGokul Rangarajan
How to effectively start market research in the health tech industry by defining objectives, crafting problem statements, selecting methods, identifying data collection sources, and setting clear timelines. This guide covers all the preliminary steps needed to lay a strong foundation for your research.
"Market Research it too text-booky, I am in the market for a decade, I am living research book" this is what the founder I met on the event claimed, few of my colleagues rolled their eyes. Its true that one cannot over look the real life experience, but one cannot out beat structured gold mine of market research.
Many 0 to 1 startup founders often overlook market research, but this critical step can make or break a venture, especially in health tech.
But Why do they skip it?
Limited resources—time, money, and manpower—are common culprits.
"In fact, a survey by CB Insights found that 42% of startups fail due to no market need, which is like building a spaceship to Mars only to realise you forgot the fuel."
Sudharsan Srinivasan
Operational Partner Pitchworks VC Studio
Overconfidence in their product’s success leads founders to assume it will naturally find its market, especially in health tech where patient needs, entire system issues and regulatory requirements are as complex as trying to perform brain surgery with a butter knife. Additionally, the pressure to launch quickly and the belief in their own intuition further contribute to this oversight. Yet, thorough market research in health tech could be the key to transforming a startup's vision into a life-saving reality, instead of a medical mishap waiting to happen.
Example of Market Research working
Innovaccer, founded by Abhinav Shashank in 2014, focuses on improving healthcare delivery through data-driven insights and interoperability solutions. Before launching their platform, Innovaccer conducted extensive market research to understand the challenges faced by healthcare organizations and the potential for innovation in healthcare IT.
Identifying Pain Points: Innovaccer surveyed healthcare providers to understand their difficulties with data integration, care coordination, and patient engagement. They found widespread frustration with siloed systems and inefficient workflows.
Competitive Analysis: Analyzed competitors offering similar solutions in healthcare analytics and interoperability. Identified gaps in comprehensive data aggregation, real-time analytics, and actionable insights.
Regulatory Compliance: Ensured their platform complied with HIPAA and other healthcare data privacy regulations. This compliance was crucial to gaining trust from healthcare providers wary of data security issues.
Customer Validation: Conducted pilot programs with several healthcare organizations to validate the platform's effectiveness in improving care outcomes and operational efficiency. Gathered feedback to refine features and user interface.

3. Health data and its management
• Most healthcare data has been traditionally static—paper files, x-ray films,
and scripts (Analogue);
• Healthcare has entered the digital age late compared to financial sector, for
example;
• Healthcare professionals are different from engineers and ICT professionals
in particular;
• Evidence in ICT for health does not lend itself to the healthcare profession
“clinical trials” approach, for example;
• Healthcare is about life and death for and individual and a population which
means more cautious approach to data management.;
• Health data management is not formally taught in most health science
schools.
4. Terminology
• Big data,
• Data revolution,
• Data explosion,
• Open data,
• Open data commons,
• Data science and data scientist,
• Data analytics.
5. Data, information, knowledge, wisdom
• A collection of data is
not information;
• A collection of
information is not
knowledge;
• A collection of
knowledge is not
wisdom;
• A collection of wisdom
is not truth.
6. Big data can be described as:
• Complex;
• No unified structures;
• Multiple sources from decentralized (distributed) data
sources;
• Multiple types of data;
• Unorganized and changing all the time;
• Resulting from a combination of big transaction data, big
interaction data and big data processing.
7. The difference between big data and (large)
databases
• Large databases have been employing the traditional well-established
format for data capturing, processing, storage, sharing, visualization,
merge and purge where data are well defined, structured, following a
specific data model, standard reporting, well defined set of operators
usually registered and has defined target users, etc.
• Example of these are:
• The Global Health Observatory (GHO). The GHO database provides access to an interactive
repository of health statistics. Users are able to display data for selected indicators, health
topics, countries and regions, and download the customized tables in Excel format
(http://www.who.int/gho/about/en/);
• The (US) National Cancer Data Base (NCDB) is a nationwide oncology outcomes database
that currently collects information on approximately 70% of all new invasive cancer diagnoses
in the United States each year (https://www.facs.org/quality-programs/cancer/ncdb).
8. Characteristics of ‘Big’ Data
• The original 3 Vs
Volume (size of databases and their multiplicity)
Variety (structured, unstructured, numbers, text)
Velocity (real time and continuous collection)
• The additional 3 Vs
Veracity (Quality) (ability to triangulate with multiple sources)
Volality (ability to keep time-series data)
Validity (primary source of data collection)
The final V
Value
9. Sources of big data in healthcare
• Clinical information systems
• Electronic health records (EHRs)
• Health information exchanges
• Patient registries
• Patient portals
• Claims data from payers
• Research studies
• Genetic datasets
• Public records
• Web searches
• Social media
• Devices, sensors and other wearables
• Financial transactions.
10. Big data in healthcare
• By definition, big data in healthcare refers to electronic health data sets so
large and complex that they are difficult (or impossible) to manage with
traditional software and/or hardware; nor can they be easily managed with
traditional or common data management tools and methods.
• Big data in healthcare is overwhelming not only because of its volume but
also because of the diversity of data types and the speed at which it must be
managed.
Source: Frost & Sullivan: Drowning in Big Data? Reducing Information Technology Complexities and Costs for Healthcare
Organizations. http://www.emc.com/collateral/analyst-reports/frost-sullivan-reducing-information-technology-complexities-ar.pdf,
• Structured vs. unstructured health data. It is estimated that 80% of medical
data is unstructured and is clinically relevant;
• Data resides in multiple places like individual EMRs, lab and imaging
systems, physician notes, medical correspondence, claims etc.;
11. Patient-centered vs. disease-centered
approach driven by big data
Disease-centered
• Decision-making is centered
around the clinical expertise and
data from medical evidence and
various tests;
Patient-centered
• Patients actively participate in
their own care and receive
services focused on individual
needs and preferences, informed
by advice and oversight from
healthcare providers.
13. Target 3.8: Universal Health Coverage
An integrated approach
• Approved by the UN General Assembly in September 2015;
• 17 goals, 169 targets;
• UHC: all people receiving the services they need without incurring financial
ruin; strong equity emphasis (2012 UN General Assembly resolution);
• Focus on social determinants of health;
• Must simultaneously monitor coverage of interventions and financial
protection:
• Tracer interventions (some are in specific targets, others can be added): e.g. family
planning, antenatal care, skilled attendance at birth, immunization, ART, TB treatment,
hypertension treatment, diabetes treatment etc.
• Financial protection indicator: people incurring catastrophic expenditure / due to health
expenses.
• UHC is the place to promote and monitor an integrated health agenda;
equity is hardwired into UHC and the SDG; country-specificity central;

18. Big data for healthcare systems
• Collaborate to improve care and outcomes. Healthcare is never
provided by one sector or agency: public, private, military, charities,
United Nations, etc. Data in these systems is fragmented, not
coordinated, duplicate and incomplete. Big data analysis cane help;
• Increase access to healthcare using a combination of themes and tools
including GIS mapping of population density, migration and people’s
movement, environmental factors (water supply, sanitation, air
pollution, traffic, deforestation, natural disasters, etc.);
• Build sustainable healthcare systems: better governance and
leadership, manage costs, improve HR performance, equitable access
to medications, pharmaceutical products, complete, timely and secure
information.
20. Big Data for public health
1) Knowledge discovery allows health researchers and then decision makers
to create knowledge and evidence from data sets of different times,
sources, types and formats;
2) Disease prediction using patterns and models based on data sets related to
humans, animals, materials and environment;
3) Big Data is a tool that will enable finding patterns that help in analysis to
spot trends and take corrective steps in global health;
4) Using the tools of public health informatics, medical informatics,
bioinformatics and medical imaging to integrate different types of data
(patient/personal, public, diseases, molecular);
4) Integrated approach for health data management (web, mHealth, health
records, smart cards, database management systems) applying open
standards for interoperability.
21. Public health: disease prevention
• Public health is mainly concerned with “disease” prevention for both the
individual and the population;
• Two steps required to achieve maximum prevention:
• Research in the public health field under consideration aiming to identify risk factors, which is
basically intensive data collection and analysis;
• Interventions to improve the conditions leading to this risk and introduce improvements in
public health.
• Active and smart linkage between the health conditions and the identified risk
factors through big data analysis (correlation and not causation relationship).
• Social determinates of health: life style, education, poverty, water supply,
sanitation, politics, policies, etc. have direct impact on health conditions;
• The complex interplay of biological and non-biological factors (Genome and
exposome).
22. Psychological Language on Twitter Predicts
County-Level Heart Disease Mortality
They concluded that “Capturing community psychological
characteristics through social media is feasible, and these
characteristics are strong markers of cardiovascular
mortality at the community level.”
23. Genetic Epidemiology and the Future of Disease
Prevention and Public Health
(M. Khoury http://epirev.oxfordjournals.org/content/19/1/175.full.pdf+html)
• The Impact of genetic epidemiology on the future of public health:
1) Will provide data on the public health Impact of human genes and their Interaction
with preventable risk factors on disease morbidity, mortality, and disability in
various populations;
2) Will provide data to guide health policy guidelines on the appropriate use of
genetic testing in disease prevention and public health programs;
3) Will provide data to evaluate the Impact of population-based prevention programs
that reduce morbidity and disability associated with disease genes
4) Will provide data on the laboratory quality of genetic testing;
5) Will become increasingly needed In core training programs In epidemiology and
public health;
6) Will provide core quantitative disease genetic risk information In integrated and
online genetics Information systems used by medical and public health
professionals and the public.
24. Healthcare: diagnosis
• Aims to determine which disease or condition explains a person's
symptoms and signs. Healthcare professional(s) collects data that is
required for diagnosis and to understand better the condition from
history (asking questions and referring to the health/medical
record) and physical examination of the person seeking healthcare
(using medical expertise, equipment, devices and diagnostics);
• Data collection, analysis and making a decision making are central to
the process;
• Computer-assisted diagnosis (data processing) can be done by
providing the computer with symptoms to allow the computer to
identify the problem and diagnosis based on models already stored in
its programmes.
25. Data helps in diagnosis of diseases
• The existing evidence;
• Existing experience;
• Gene mapping;
• Age-related data;
• Diagnostics and devices;
• Image and ultrasound processing, analysis and identification of “irregularities”;
• Disease and personal history;
• Family history;
• etc.
26. Predictive analytics increase the accuracy of
diagnoses
• Seven ways predictive analytics can improve healthcare:
Linda A. Winters-Miner,
https://www.elsevier.com/connect/seven-ways-predictive-analytics-can-improve-healthcare
1) Predictive analytics increase the accuracy of diagnoses.
2) Predictive analytics will help preventive medicine and public health.
3) Predictive analytics provides physicians with answers they are seeking for
individual patients.
4) Predictive analytics can provide employers and hospitals with predictions
concerning insurance product costs.
5) Predictive analytics allow researchers to develop prediction models that do not
require thousands of cases and that can become more accurate over time.
6) Pharmaceutical companies can use predictive analytics to best meet the needs of the
public for medications.
7) Patients have the potential benefit of better outcomes due to predictive analytics.
27. IBM Watson
• Described as the “physicians’ diagnosis and treatment assistant
supercharged with Big Data and analytics”;
• A compilation of 21 supercomputer subsystems, is the first of a new
class of industry-specific analytical platforms and decision support
systems that use deep content analysis, evidence-based reasoning
and natural language processing to support faster and more precise
diagnostics and clinical decision making;
• Watson takes in data from patient history, family history,
symptoms and test findings and produces a list of disease
suggestions ranked by confidence, to assist the physician in
diagnosis and treatment.
28. Case study: Big data improves cardiology
diagnoses by 17%
• Used an associative memory engine to crunch enormous datasets for
more accurate diagnoses, utilizing 10,000 attributes collected from 90
metrics in six different locations of the heart;
• Was able to find patterns and pinpoint disease states more quickly and
accurately than even the most highly-trained physician;
• The study discovered a discrimination of 90% between the two
datasets and without any human intervention. This meant that the
highly complex analyses that were done produced a discrimination
which exceeded human ability to diagnose the two conditions.

30. Big data: yes. Harm: No.
• Primum non nocere is the Latin phrase that means "first, do no harm“ as
the basic healthcare/medical principle;
• Ethical considerations and policies have to be developed and respected:
• The original purpose for which data was collected and stored. The risk of (unethical)
reuse;
• Informed consent as to the extent of knowledge and awareness of the individual to the
reason why personal data is being collected and how it will be used;
• Data substantiation to ensure high quality, timely and secure for the purpose to be
used;
• Ownership of data as to who owns the data: individual, institution, state;
• Accessibility to by whom and for what purpose;
• Accountability to both ethical and legal bodies.
