Disease InformaticsICD-11 at the doorstep
Bill and Narayana
  • By RP Deolankar
  • Presentation for 4th Nutraceutical Summit, WTC,
    Mumbai, India
  • Feb. 21-23, 2008

2
WHO
  • World Health Organization (WHO) provides a
    service which is designated as a Family of
    International Classifications (WHO-FIC)

10th version of ICD (ICD-10) has a Chapter
entitled Endocrine nutritional and metabolic
diseases
3
ICD
  • One of such service is International
    Classification of Diseases (ICD)
  • Application of Statistics and Information Science
    to establish causes of morbidity

The activity is being described as a part of
Disease Informatics
4
Disease Definition
  • The ICD has become the international standard
    diagnostic classification for all general
    epidemiological and many health management
    purposes.
  • In turn, ICD provided Diseases definitions

"Let your food be your medicine and your medicine
be your food" Hippocrates In short, most of the
diseases could be linked to food and lifestyle.
5
ICD-10
  • Endorsed by the Forty-third World Health Assembly
    (WHA) in May 1990
  • Disease Definitions are quantal
  • Domain of handpicked experts as described by
    media

Severity of the disease triggered by the virus
may be determined by the type of food had been
eaten by the subject.
6
Scope for improvement
  • Severity of Disease Diseases are quantitative
  • Holistic approach Multiple morbidities interact
  • Throwing open portal to Doctors, Health Workers,
    Educationists and Spiritualists

Dr. T. B. Ustun
7
Scope for improvement in clinical research
  • Multiple morbidity ? Multiple hypotheses
  • Bayesian applications
  • What can be done?
  • As most of the functional foods serve as
    multiple remedy and also could reduce side
    effects of drugs, create task force for
    statistical methods in this area

8
Objectives of the presentation
  • Discuss How to use platform provided by
  • ICD-11 for
  • Defining the diseases with least error so that
    those are understood, prevented and reversed
  • Identifying most of the targets to combat a
    cluster of diseases, understand spatial continuum
    through working on Disease Causal Chains and
  • Designing a holistic solution to the disease
    problem

9
Health of an individual
  • Wellbeing Disease
  • Loosing the wellbeing is proportionally gaining
    the disease

Wellbeing guards Good food Superb
lifestyle Complementary Nutraceuticals
10
Medical check-up
  • Revealing certain events in the health history of
    an individual
  • Three aspects of Medical Check-up
  • Attempt to hunt priors (Backend events)
  • Understand present (Current event)
  • Predict posteriors (Frontend events)

11
Disease Causal Chain or Web
  • Events linked together
  • Chain could be reversed due to intervention
  • Pruning the Frontends could stimulate branching
    in the chain

12
Factors (Components)
  • Drive events from backend to frontend
  • Proxy, Overlapping, Independent, Mediators and
    Moderators
  • Events could be modulated through altering
    factors

Prof. HC Kraemer
Factors are shown by arrows

13
Components working together
  • It is not A B
  • It is A B AB

Genes load the gun, the environment pulls the
trigger Prof. Kenneth Olden
Point to ponder Why certain probiotics reverse
viral diarrhea?
14
Ancient Indian Model of Human Body Computer
  • Human Somatic body Vitality Mind
    Intellect Bliss (Panchakosha)
  • Intellect (Central Processing Unit) Self/ Ego
    (Software) Memory (Free space, Pen Drive/ Hard
    Disk) Mind/ senses (Program) Life history
    (Data)

15
Human Microbial Organs
  • Gut Associated, Vagina Associated, Skin
    Associated etc (Eco-organs)
  • Being described as Human Microbiome

Prebiotics Probiotics Synbiotics
Prof. Stig Bengmark
16
Clinical Research
  • To understand the disease of an individual, one
    has to understand human and his body computer and
    his associated organs also

17
ICD-10 classification
  • Infectious and Parasitic Diseases
  • Cancers
  • Endocrine, nutritional or metabolic diseases etc.

18
Triviality
  • Infectious disease is not a nutritional disease
  • Nutritional disease is not an endocrine disease
  • One may have Infectious Disease Nutritional
    Disease Endocrine disease
  • i.e. Multiple morbidities but not the complex
    disease

19
Reality
  • Infection can happen due to endocrine abnormality
    and endocrine abnormality can happen due to
    malnutrition
  • Some component may occur as prior some component
    may occur as posterior
  • (Keshan disease Selenium Deficiency coxsackie
    virus B4)

20
What is neglected in ICD-10
  • Disease Causal Chain
  • Most of the traditionally established remedies
    (TER) alter disease causal chain
  • TER could alter some component of a sufficient
    cause of the disease
  • Disease definition might not regard that component

21
Rothman and Greenland
  • Sufficient and component cause model
  • (Button is not sufficient cause to switch on or
    switch off the bulb)
  • Sufficient causal mechanisms gt 1

Three sufficient causes of disease.
22
To summarize the background
  • Diseases are complex
  • Needs group effort to understand
  • Needs modern tools of information science to
    study
  • Yet can have simple solutions

23
ICD-11
  • Membership is open to all who are willing to
    register
  • Members can back their suggestions with
    appropriate evidence
  • Members can participate in online debate over
    proposed changes in disease definition
  • What can be done?
  • Register as a member, Form Disease Informatics
    Groups

24
Systematic reviews Basis of ICD-11
  • What can be done?
  • Participate in Cochrane collaboration
  • Practice of combining the results of a number of
    studies (scientific, clinical and public health)
    that address a set of related research hypothesis

25
What is Cochrane Collaboration?
  • It is a global network of dedicated volunteers
    for providing reliable source of evidence in
    health care. Evidence is in the form of
    Systematic reviews based on meta-analysis
  • What can be done?
  • Register our interest in nutraceuticals and
    functional foods, form Cochrane review group

Professor Archibald Leman Cochrane
26
Field testing of ICD-11
  • Draft version of ICD-11 shall be field tested
  • What can be done?
  • Participate in the field testing

27
Standardization of terminology
  • ICD-11 website shall provide linkage for
    standardization of terminology
  • What can be done?
  • Find out methodology so that world understands
    our terminology

28
Examples of Indian terms
  • Simple term Ama Dysbiotics (Products of
    dysbiosis)
  • Complex term Vata Body constitution described
    as Low density of the body Ectomorphy More
    gaseous Less muscle High body motility
    Linear body shape etc

Traditional Knowledge Digital Library should be
made available to ICD-11
29
Confusion due to local dialect
  • Kanjika (Indian functional food, also abbreviated
    as Kanji), a probiotic food, is a lactic
    fermented product where lactic fermentation is
    the terminal step in food processing and is
    prepared from raw material of plant origin and
    devoid of dairy product
  • Kanji is also used for porridge that is confusing

30
Confusing terms (Continued)
  • Umbil is similar to kanjika but contains lactic
    fermented milk as an ingredient or cooked plant
    material may be combined with lactic fermented
    dairy product
  • Umbil is also used in place of Kanjika by some
    people

31
Standard Terminology
MeSH, Medical Subject Headings of NLM, NIH,
USA Based on UMLS (Unified Medical Language
System) Metathesaurus
32
Standardization of Data Processing
  • ICD-11 website shall provide linkage for
    standardization of Data Processing
  • More and more Bayesian Approach would appear in
    Disease Informatics
  • What can be done?
  • Develop user friendly software

33
Standardization of Research
  • ICD-11 website shall provide linkage for
    standardization of research
  • More and more Good Practice Protocols would be
    asked for
  • What can be done?
  • Develop standard courses in Health Research,
    Project Management Software, Infrastructure and
    Equipment Management, Store and Inventory
    Management, Archive Management, Document
    Management and GLP, GCP, GCLP, GMP etc

Calcium deficiency as the front-end event due to
Chelation by Phytic acid
36
Front end events of Reduced availability of
Calcium
Front end events Backend event
No deficiency in subjects taking calcium sufficient diet Calcium deficiency (reduced availability of Calcium due to IP6)
Sub-clinical deficiency in subjects taking calcium deficient diets Calcium deficiency (reduced availability of Calcium due to IP6)
Rickets in children where component cause is calcium deficiency Calcium deficiency (reduced availability of Calcium due to IP6)
Osteomalacia / osteoporosis in elderly where component cause is calcium deficiency Calcium deficiency (reduced availability of Calcium due to IP6)
Degradation of vitamin D in the liver due to calcium deficiency Calcium deficiency (reduced availability of Calcium due to IP6)

Front end events of Vitamin D deficiency
(Avitaminosis D syndrome, I)
D Finally, a vitamin makes the grade. Several
new studies suggest that the so-called sunshine
vitamin (because its produced in skin exposed to
sunlight) may protect against cancer. One study
showed that as blood levels of vitamin D go up,
womens breast cancer risk goes down. Another
found that fairly large amounts of vitamin D
lowered the risk for pancreatic cancer by about
