2.  Health and Public Health
 Public Health in India
 Before the Colonial period
 During the Colonial period
 After the colonial period
 Essential Public Health Functions
 Mortality transition in India

3.  TheWorld Health Organisation defines
Health (of an individual) as the state of
complete physical mental and social well-being
and not merely the absence of disease or
infirmity.
 World Health Organisation, however, does
not define Public Health.

4.  Death, on the planet Earth, is inevitable.
 A large number of deaths are premature.
 A substantial proportion of deaths can be
avoided.
 Public Health is related to preventing
premature and unavoidable deaths.

5. Exposure to Risk

Disability Death

6.  If the disease condition is avoided, the
probability or the chance of death or
disability can be reduced.
 Public Health is therefore described as the
science and art of preventing diseases,
prolonging life and promoting health (of
individuals) through organised efforts and
informed choices.

7.  Public Health deals with the group of people
rather than individuals.
 Dimensions of public health
 Health promotion
 Disease prevention
 Early diagnosis and prompt treatment
 Disability limitation
 Rehabilitation

8.  The Indian approach to health is enshrined in
the concepts and principles of Ayurveda
which means the ‘science of life’.
 Ayurveda is one of the oldest system of
health care in theWorld.
 Ayurveda deals with both preventive and
curative aspects of health.
 Health defined byWHO is very similar to
concepts of Ayurveda.

9.  The western approach of avoiding diseases,
death and disability, traditionally focused on
personal hygiene and public sanitation during
the 19th Century.
 This approach, combined with better food
availability, paid rich dividend in the
developed countries in reducing morbidity
and mortality.

10.  Epidemiology
 Measurement of disease conditions in relation to
the population at risk.
 Statistics
 Collection, presentation, analysis and
interpretation of epidemiological data.
 Health Services
 Services directed towards meeting the health
needs of the people.

11.  Little is known about public health activities
before the colonial period.
 Main stream system of health care was
Ayurveda.
 Home-based care appeared to be the
dominant feature.
 There appeared little organised efforts or
institutional care to treat diseases and
prevent deaths.

12.  Evolution of public health system during the
colonial period followed the same path that
was followed in Britain.
 Public health efforts were focused largely on
protecting British civilians and army
cantonments.
 Sanitation was given the top priority.
 Focus was also on early detection and control
of contagious diseases – cholera and plague.

13.  Training and research Institutions in public
health.
 Public health legislation.
 Sanitary departments
 Ascertaining local sanitary conditions.
 Vital registration.
 Monitoring disease trends.
 Vaccination programmes.
 Technical advice on control of epidemics.

14.  Restriction of public health efforts to British
civilians and military established was a major
constraint.
 Majority of Indian masses remained deprived
of the dividends of these efforts.
 At the time of Independence only 3 per cent
households in India had toilets.
 Water, drainage and waste disposal services
were utterly lacking.

15.  Although, public health efforts were
restricted to British civilian and military
establishment, they had impact on Indian
masses.
 Mortality spikes were sharply reduced.
 Mortality from cholera and plague was sharply
reduced.
 Diseases like malaria and gastro-enteritis
continued to take heavy toll.

16.  Evolution of public health care system in
Independent India was shaped by two
important factors:
 The Report of First Health Survey and
Development Committee (Bhore Committee)
constituted during the colonial rule.
 Emergence of modern medical technology for the
prevention and control of diseases, especially
communicable diseases.

17.  Appointed in 1943.
 Recommended comprehensive remodeling of
health services.
 Integration of preventive and curative health
services at all levels.
 Hospital-based health care system.
 Development of primary health centres in two
stages.
 Training in Preventive and Social Medicine.

18.  The short-term plan
 A PHC for every 40000 population.
 PHC to be manned by 2 doctors, 4 PHN, 4
Midwife, 1 Nurse, and others.
 The long-term plan
 A primary health unit for every 10-20 thousand
population with 75 beds.
 Secondary unit with 650 bedded hospital.
 District unit with 2500 bedded hospital.

19.  Mass production of antibiotics.
 Availability of vaccines for diseases having
high mortality and disability rates
 Tetanus
 Diphtheria
 Pertussis (Whooping Cough)
 Measles
 Poliomyelitis

20.  The recommendations of Bhore Committee
and the availability of preventive and curative
medical technology resulted in the evolution
of hospital-based public health system.
 The public health arrangements created
during the colonial period were replaced by
hospitals and health centres.
 Public health services were merged with the
medical services.

21.  Bhore Committees recommendations were
accepted only partially.
 One primary health centre for every 30 thousand
population.
 Only 6 beds in each primary health centre.
 Only one doctor.
 Truncated paramedical staff.
 The situation has remained largely
unchanged.

22.  Since Bhore Committee, numerous
committees were constituted to evolve the
public health system.
 Some of the recommendations of these
committees were adopted; some were not by
the government.
 All committees retained the core of the
model recommended by the Bhore
Committee.

23.  MudalliarCommittee(1962)
 Strengthen PHCs before establishing new ones.
▪ PHC should provide preventive, promotive and curative
services.
 Strengthen sub-divisional and district hospitals.
 Creation of All India Health Services.
 Chaddha Committee (1963)
 Malaria worker to function as multipurpose
worker.

24.  Mukherjee Committee (1965)
 Separate staff for family planning programme.
 Malaria activities to be de-linked from family
planning activities.
 JungalwalaCommittee (1967)
 A unified approach for all problems instead of a
segmented approach for different problems.
 Medical care and public health programmes to be
put under charge of a single administrator.

25.  Kartar Singh Committee
 Concept of MPW(M) and MPW(F).
 One PHC to catre 50 thousand population.
 Each PHC should have 16 SHC (3-3.5 thousand
population).
 Shrivastav Committee
 Creation of bonds of paraprofessional and
semiprofessional health workers from within the
community itself.
 Development of a “Referral Services Complex.”

26.  Bajaj Committee
 Formulation of National Medical & Health Education
Policy.
 Formulation of National Health Manpower Policy.
 Educational Commission for Health Sciences.
 Health Science Universities in various states.
 Health manpower cells.
 Vocationalisation of education at 10+2 levels as
regards health related fields.
 Realistic health manpower survey.

27.  A population based normative approach is
adopted for establishing hospitals and health
centres
 SHC – One for every 5000 (3000 in hilly/tribal
areas) population.
 PHC – One for every 30000 population (20000 in
difficult areas) with 4-6 indoor/observation beds.
 CHC – One for every 80-120 thousand population
with 30 beds.

28.  The norms are for government institutions
and are for the rural areas only.
 For the urban areas, no norms have been
defined.
 Nearly all government civil and district
hospitals and most of the CHCs are located in
the urban areas.
 No information is available about the private
health system.

29. Institution Reference Number
SHC 2007 145272 More than 6 SHC for each PHC,
on average
PHC 2007 22370 More than 5 PHC for every CHC,

30.  One fall out of the hospital-based public
health approach was the neglect of public
health legislation.
 A Model Public HealthAct was drafted in
1950 by the Government of India.
 It was revised in 1987.
 This Act is yet to be adopted by any of the
constituent state of the country.

31.  The hospital-based public health system led
to the medicalisation of the system.
 The focus has been on medical services.
 Public health services have largely been
neglected.
 Poor public health services result in high cost
of illness, debility and death.
 The main sufferer are the people, especially
the poor and deprived.

32.  The epidemiological and statistical
dimensions of public health have been
grossly neglected.
 Lack of epidemiological and statistical
database affected public health planning.
 In the absence of necessary information,
planning reduced to a normative, mechanical
exercise, often out of context to people’s
needs.

33.  The problem gets complicated because of
social, economic, cultural and environmental
diversity that leaves normative planning
virtually redundant.
 Decentralisation of the health system could
not succeed because of the lack of
epidemiological and statistical information
necessary for planning for public health
services.

34.  Public health in India is ‘hospitalised.’
 Health planning is concerned more with the
health of the health care delivery system
(hospitals and health centres) then the health
of the people.
 The remedy was sought in terms of specific
National health and disease control
programmes.
 There are numerous such programmes.

35.  Reproductive and child health programme.
 National tuberculosis control programme.
 National malaria control programme.
 National blindness control programme.
 National water born disease control
programme.
 National leprosy eradication programme.
 National iodine deficiency control
programme.

36.  All National disease control programmes are
implemented through the existing
government hospitals and health centres.
 Over the years, a campaign approach has
been evolved to implement many of the
national health and disease control
programme.
 Successful campaigns have often been
followed by unsuccessful maintenance.

37.  Focus on medical services.
 Neglect of public health services.
 No modern public health regulation.
 Lack of systematic planning.
 Poor sustainability of public health efforts.
 Absence of epidemiological and statistical
skills at district and below district level.
 No micro-level planning, no public health
action.

41. Widespread existence of preventable
diseases and deaths is a disgrace to
the society which tolerates it.
