The prevailing perception that technological development facilitates universal empowerment and tran-
scends the social domains of discriminations is now challenged by comprehensive studies. Technology
itself is a domain of inequality and it accentuates more inequality with technology gradually favoring the
privileged sections and the societies. The healthcare technology, which otherwise could have brought
miracle achievements in attaining universal health standards, however, has failed to do so due to the in-
herent inequality in access to healthcare technology. The growing dominance of monopoly houses on
healthcare technology and marginalization of indigenous health technology makes access to technology
with a new domain of inequality. With comprehensive empirical data, the present paper investigates into
this domain of inequality and argues that a move towards global well being demands a radical restructur-
ing of the global domain of healthcare technology.

Introduction
“Medicine arose out of the primal sympathy of man with
man; out of the desire to help those in sorrow, need and
sickness” (Osler, 1913).
Since the era of modern medicine following discovery of an-
tibiotics & vaccination, the health of people in general has un-
dergone a sea change. Centre for Disease Control and Preven-
tion (2013) has identified vaccination as the topper of the list
that has impacted on public health. Centre for disease control
estimates that in the 20th century about 25 years have been
added to life expectancy for the US citizen. Though the accu-
rate global data for understanding impact of medical or health-
care technology is not readily available, United Nations reports
suggest that life expectancy at birth for the world population
rose from 48 years in 1950-1955 to 68 years in 2005-2010 (UN,
2012). The report illustrates the transition of different countries
through phases of economic developments and the change in
the death pattern. It has been seen that with increasing eco-
nomic and social development, death from the type I cause (that
primarily includes infectious disease) declines.
In spite of continued efforts by global agencies, national
governments and professional work groups of the benefit of
healthcare technology are yet to touch the lives of millions of
people across all the continents. Providing access to medicine
and health technology has been a priority in the Millennium
Development Goals (UN, 2001). There are government inter-
ventions (Department for International Development, 2004) to
promote dissipation of healthcare technology benefits, but there
still lies an access gap for all sorts of health technologies not
only medicines. The lack of access to advance diagnostic tech-
niques, prosthesis or blood transfusion technology is rarely
discussed if compared to concerns for medicines. Similarly
most debate on healthcare technolog y access ends up discussing
factors of cost and affordability, but the equally important
problems of politics and administration, delivery, distribution
and technology adoption remain somewhat neglected.
Fundamental Theory
Historically it was observed that people who are placed con-
veniently at the socio-economic hierarchy stood a better chance
at life to live longer. What devastated the world as killer disease
has changed from cholera and bubonic plague in past centuries
to death from cardiovascular accidents and cancer in present era,
but the association of socioeconomic status (SES) factors with
survival remains across the disease—thus the risk of disease
type changes but the association of SES factors persist across
the spectrum.
To understand SES status factor one needs to consider three
core elements-education level, employment & work, and eco-
nomic state. The first of the factor education is responsible for
knowledge and skill, values and behavior that will shape the
structure of work opportunities. The second core element of
SES factor is employment & work—a person in employment is
paid, but a person doing productive work (like house wife) may
not be paid. The employment or work can be categorized in a
scale, higher ranked jobs confer more autonomy, economic
return and happiness. Third core component of SES factor is
economic well being that translates to household income, per-
sonal earning, wealth or economic hardships. It is important to
understand the impact of each of the core factors separately on
health. Averaging out the SES factor while studying a health
phenomenon might leave enough gap in knowledge, to make
policy related intervention difficult. Effect of education on
S. HAZARIKA, A. R. DUTTA
health and health on education, effect of economic factor on
health or health on economic factor and effect of employment
or occupation on health and vice versa are not interchangeable
propositions.
In the United States of America, National Longitudinal
Mortality Study (NLMS) is carried out under sponsorship of the
National Cancer Institute, the National Heart, Lung, and Blood
Institute, the National Institute on Aging, the National Center
for Health Statistics and the US Census Bureau for the purpose
of studying the effects of differentials in demographic and
socio-economic characteristics on mortality. Confirmation of
association of SES factor with mortality comes from National
Longitudinal Mortality Study. Researchers have pointed out
strong association of mortality with income and education lev-
els. While income is mostly a changing variable across the
years and education remains static in later part of an indivi-
dual’s life, it is interesting to note that the factor of income &
education compete with each other to influence ones chances of
longer life (Sorlie, Paul, Eric, & Jacob, 1995)
Link & Phelan proposed a fundamental cause theory that
seeks to bridge association between SES and health outcome
over a long time (Link & Phelan, 1995).The observations made
in the theory stems from the fact that SES of an individual
determines the access to important resources that allow the
individual to avoid diseases and their consequences. SES
dictates risk factors and disease outcomes that change over time.
Thus in fundamental cause theory SES is seen as the basic
factor to influence health, morbidity & mortality. The list of
resources that need to sustain life is varied and includes wealth,
knowledge, skills, power, and social connections. It has been
seen over time that the infectious diseases that used to anni-
hilate large populations have been somewhat controlled in the
developed world by increased sanitation and various other
public health measures. In the developed world the leading
cause of death now includes heart diseases, stroke and cancer
and now we can see that importance of factor like sanitation or
drinking water on mortality and survival has decreased but the
new factors like smoking, lifestyle have gained importance
which again are dependent on SES. We can understand that
controlling some disease shift our focus to newer diseases that
gain importance and we get to know newer cause association
mechanisms. Today when researchers will formulate newer
technology or drugs to treat the new killers people in the higher
level of SES strata will stand higher chances at survival as
resources can be allocated for obtaining such benefit. Thus the
historically evident observation remains that no matter what-
ever emerges as new risk factor that effects population health at
any given point of time those who are at a higher SES ground
will tend to fare better and the social disparities in health
remain.
Empirical research has supported Fundamental cause theory
for newer global epidemics of this century. One important study
with cholesterol lowering drugs was undertaken to understand
the socio-economic bias of utilizing newer interventions.
Cholesterol is a risk factor for cardiovascular disease which is
emerging as an important cause of mortality in the developing
world. Chang et al (Chang & Lauderdale, 2009) used three sets
of National Health and Nutrition Examination Survey
(NHANES) data sets that included 1976-1980, 1988-1994, and
1999-2004. The researchers observed the blood cholesterol &
Lipid level in an effort to understand the effect of new effective
class of costly drugs (statins) that entered the healthcare market.
The study used the poverty income ratio, that takes into account
family’s income to its appropriate poverty threshold given
family size and composition. In analyzing the differential
pattern of cholesterol reduction, the statistics suggested that
people with higher income scale have experienced a much
larger decline in lipid levels than those at the lower end. For
example, among men, LDL (low density lipoprotein) decreased
by 20.6 units over this period for high-income persons (Poverty
Income Ratio = 5), but by only 10.3 units for those at the
poverty level (Poverty Income Ratio = 1). Hence, the decline
experienced by the wealthy was nearly double than experienced
by the poor. While it is important to note that average
cholesterol levels declined during this period at all income level
still there were significant disparities of gradients favoring the
wealthy. In conclusion, Chang et al commented “...wealthy
have disproportionately benefitted from the development of a
technology to treat this new risk factor, which will likely extend
to disparities in cardiovascular mortality and, ultimately, con-
tribute to the maintenance of disparities in overall mortality”.
Access to Healthcare Technology
In a simplified nontechnical way we can define “Access” as
one’s ability to obtain a product or service. So if we have to
translate the meaning to health care access, it will mean
people’s ability to get treated for diseases they have, or people’s
ability to get services that provide them health and well being
free of disease.
Access is not to be understood as a simple matter of logistics
to make a technology available or affordable to a population in
question. The question of access is also related to social values,
cultural bias, economic interests and prevailing political
processes that govern the healthcare system. Access can be seen
as a continuous process that involves a set of actors over a long
period of time throughout different activities. Frost and Reich,
has summarized the conception of Access on four “A”s:
Architecture, Availability, Affordability, Adoption (Frost &
Reich, 2009).
Architecture involves the organizational structure that co-
ordinates the next three “A”s to produce access. To make a
technology or product available one need to consider manu-
facturing, storage, distribution and delivery functions. Afforda-
bility of a technology has multiple dimensions. Whether it is
affordable to end users directly or whether it is affordable for
the healthcare system acting for population or whether the
technology needs to be affordable to a central government
planning all are encompassed within the broad meaning of
affordability. At all these levels one need to anticipate the fact
that the product or service is not out of reach to the individual
or society. Last dimension of access is Adoption that involves
global and local levels. A technology needs to be accepted for
use by the end users, so that a healthy demand is generated for
its continued availability.
Once the concept of access is defined, we may proceed to
understand how the activities under each component of access
translates a healthcare technology product or service to make a
difference in disease outcome, or more generally speaking
improving health. It is necessary to ensure that mere availability
or use of a technology or product is insufficient, one has to
ensure appropriate and right use of healthcare technology for
the intended purpose, to have an impact over the population

health.
While use of a particular technology for the intended purpose
is desirable, one can not underestimate innovative users to find
another use. It can not be assumed that non-intended newer use
will conform to the code of healthcare benefit or patient safety.
History of healthcare innovation is replete with examples of
employing simple resources to achieve outstanding outcome.
One example is Foley Balloon cathater that has the primary use
of draining an obstructed urinary bladder. The sight of the
cathater serving as tubing for passage of urine from inside the
body to a urine collecting bag is all too familiar for any visitor
to a hospital. Necessity and innovation has given the simple
rubber tube its other uses like as a tubing to drain blood or fluid
from chest, drainage of pus from internal body abscess or even
as a effective Torniquet to tie around a limb to stop bleeding, so
on. One interesting anecdote is transformation of Female
condoms to fashion accessories (Steve, 2005). In Zimbabwe
Female condoms were distributed by aid agencies, which costs
2 cents each. The condoms were obtained to make a profitable
fashion accessories by cutting off the plastic, keeping the
rubber ring for use as bangles. The rubber rings are colored and
made in a pack of three could be sold for $2. While discussing
the problem of access in their publication, Frost and Reich
illustrated this case of technology adoption as a reminder to the
difficulty arising out of unpredictable human behaviour, which
lead to wastage of a product by some people and thereby
starving some other people of the products benefit.
The socioeconomic barrier is an important factor that gove-
rns access to healthcare technology and its benefits. The differ-
ential pace of diffusion of healthcare technology can also be
attributed to problem of access, apart from level of income and
education. It can be argued that a dual strategy of improving
socioeconomic condition along with good governance to im-
prove access to healthcare technology can deliver better results
for population health.
Following our orientation on fundamental cause theory and
the concept of access and its components we intend to review
some of the healthcare technologies for our further under-
standing before finding an approach to solve the problem of
unequal diffusion of healthcare technologies.
Example 1: Prosthesis
From the very beginning mankind probably pondered over
the unfortunate loss of limb in hunting misadventures and acci-
dents. Later with the formation of social groups the phenome-
non of war probably claimed its fair share of limbs. In history
of medicine the story of limb amputation and development of
prosthesis paralleled each other. Its historical twists and turns
paralleled the progress of civilization itself. Prostheses were
developed for function, cosmetic appearance, and to provide a
psychological sense of wholeness. These very patient needs
have existed from the dawn of time till the present time. Even
today modern healthcare technology innovations are directed
towards development of newer devices like implantable joints,
organs and devices for functional restoration like artificial
lenses and pacemakers. In our discussion for the sake of sim-
plicity we are taking the case of limb prosthesis and artificial
heart valves (valve prosthesis).
Limb Prosthesis
In last two centuries industrial revolution and the world war
brought about considerable advancement in prosthesis fuelled
by money available to amputees and soldiers. With large num-
ber of effected population it was right to expect a forced devel-
opment in functional limb prosthetics. In the present world
there are still large populations of amputees from landmine
blasts, accidents or polio.
Developing an appropriate prosthetic/orthotic care is challen-
ging. Poonekar (Poonekar, 1992) identifies a list of prevailing
factors affecting prosthetics and orthotics in India, but these
could apply to much of the developing world. Apart from the
socio-economic, cultural factors the researcher has identified
other factors like climatic condition, local availability of tech-
nology & material—which comes to the domain of access.
Other researchers too comment on access issues of prosthesis
from the view point of making it available where needed. Prop-
erly constructing, fitting, aligning, and adjusting a prosthetic
limb requires a high level of skill and despite the high demand
for this expertise, there are very few training programs in low-
income countries. The limited number of skilled person itself
creates a problem of access to prosthesis. Studies by the World
Health Organization (WHO) indicate that while the current
supply of technicians falls short by approximately 40,000, it
will take about 50 years to train just 18,000 more skilled pro-
fessionals(Walsh & Wendy, 2005).
Keeping aside the financial implications, researchers are
looking to identify the factors and trends to promote an equi-
table access to technology of prosthetics in the developing
world. There are two dominant but often conflicting approaches
to circumvent the problem of access to prosthesis. In the “top-
down” approach of buying and implementing technology
packages from the west, money is spent on procuring and dis-
tributing the benefit. The other approach involves developing
the simplistic traditional technology with local skill and mate-
rial on a sustainable basis. Donor agencies all over would read-
ily supply state of the art limbs to amputees of mass disaster.
Whereas national governments in resource poor setting prefer
to patronize the second approach in a more long term perspe-
ctive. The success of Jaipur foot (Box 1), indigenously devel-
oped in India with local expertise, material and a continuous
interaction between manufacturer and the end users is a testi-
mony to the second approach. This experiment needs an elabo-
ration.
While discussing antipersonnel mine blast victims rehabilita-
tion it has been pointed out that access to medical facility, secu-
rity, government policy & administration are very important
limiting factors alongside the socioeconomic factors.
Matsen in his study of Vietnamese amputee population has
carried out a field survey and had encountered some interesting
facts that highlight the difficult problem of access to prosthetic
services, based on various governmental considerations (Mat-
sen, 1999). In Vietnam various international agencies are pro-
viding prosthetic services through the government. Like many
developing countries savaged by wars in the twentieth century,
Vietnamese suffer from undetonated mine fields. There are
other (social) causes of limb losses like road traffic accidents
too. The case study carried out by Matsen, to understand access
to healthcare technology in the form of prosthesis showed that
allotment of prosthesis was following a hierarchy. For receiving
the benefit the favored people are North Vietnamese war heroes,
followed by public officials, than the north Vietnamese veterans,
and lastly the people who had amputated limb from Non War
related injury or disease. Distribution of prosthetic part too

Jaipur foot is a familiar name for who live in the war zones of
Afghanistan to Iraq, from Angola to Srilanka. This below knee prosthesis
made with wood and rubber or aluminium and rubber has changed
millions of life in the developing world. Lightness and mobility are its
most attra ctive fea tures. Pe ople spen d close to $30 on a foot and wear it to
run, cli mb trees and ri de bicycl es. Pr ice is one of the fact or fav ourin g the
Jaipur Foot but the r eal appeal of the techn ology lies in the fact that it take s
only 45 minutes to build and a few hours to fit on to the patient, and lasts
for more than five years. Being developed by crafts man in a third world
country, the technology is perfectly suited to the lifestyle needs of
countries such as India and Afghanistan, where people sit, eat, sleep and
pray on the floor. The cultural mismatch of western world prosthesis
which came with a fitted shoe (poor people do not wear a shoe! Even if
poor people have shoes, they do not wear it in ankle deep mud of paddy
fields) that limited the person from squatting, crossed leg sitting was a
nightmare.
Pandit Ram Chandra Sharma is credited as the inventor and designer
of the J aipur fo ot, when h e was o n a vi sit to SMS hosp ital to t each art as
a therapy to polio effected children, in 1960. “Masterji” as he is widely
known, tried to solve the problems faced by the young amputee with
imported artificial limbs, by creating a limb locally from vulcanized
rubber hinged to a wooden limb and a pro t o type Jaipur foot was born.
Jaipur Foot has been continually innovated ever since its first devel-
opment with active involvement of Masterji. Its essence has however
remained: ease and speed of fabrication, lightness in weight, low cost
and suitability for working people in the Third World. Now Indian Space
Research Organization (ISRO)—is helping the crafts man to make a foot
from Polyurethane’s (PU)—used by the space industry in their rockets and
satellites. The se ne w gen erat ion Jai pur f oot a re unde rgoi ng field tr ials and

followed a pattern of privileged geographic province. For in-
stance, patients waited on average only 1.8 years, while in the
province of Quang Tri patients waited nearly five times as long
(average 8.9 years) before their first government-provided leg.
This waiting period has a strong correlation with the rate at
which government pensions are allotted to the patients of the
province. These finding complements the perception that the
equitable distribution of healthcare technology has many barri-
ers beyond the principal barrier of SES, the problem of access
based on prevailing political considerations, too needs to be
addressed for a solution.
Heart valve (valve rosthesis)
While most of the rheumatic fever induced developing world
heart disease has only limited access to heart valve replacement
an estimated 275,000 - 370,000 elderly patient receive valve
replacements in developed world (Zilla, Brink, Human, & Be-
zuidenhout, 2008). The luxury of cardiac surgery is only avail-
able to 8.1% of the Chinese and 6.9% of Indian population.
However, given the pace of fast growing economies of some of
these countries, it is predictable that they will soon have a high
demand for prosthetic heart valves that are affordable and that
address the specific needs of their mainly young rheumatic
heart disease patients. It is expected that lack of socio economic
progress makes outcome from heart valve surgery less accep-
table owing to post operative complication of blood coagula-
tions. In the post-operative period recipient of the prosthesis
needs to be educated for continued monitoring visits, and com-
pliance with anti-thrombolytic therapy. In developing countries
these thrombo-embolic complications are abundantly multiplied
due to lower socioeconomic state, mainly educational deficits.
There is alternative technology of biological tissue valves
which are not considered to be adequate for young patients of
third world due to the fact that biological valves tend to degen-
erate fast in younger people. The problem of access to health-
care technology in this situation comes in many packets besides
the problem of affordability that is attempted to be addressed by
locally manufacturing heart valves. One of the problems with
local manufacturing is that the technology may not be appro-
priate in the intended situation, as the third world replicas are
based on a first world objects meant for different set of patient,
and at times for different indications. There is little incentive
for the multinational companies to do active research in valve
prosthesis where profit turn around time is too long from prod-
uct design to sales turnover. The fact that most products will
have a market in the low paying developing third world in itself
undermines the issue considerably for profit seeking corpora-
tions. People with valve disease in developing world will con-
tinue to face the problem of access based primarily on their
socioeconomic status. Unless research is undertaken to develop
low cost affordable and effective solution, the gap between the
people’s needs and MNC’s commitment will continue to widen.
It is frustrating to note the fact that on one side people from
threshold countries in need of a new concept of a truly long-
lasting valve prosthesis is waiting in desperation and on the
other hand elderly patient of first world are overwhelmed by
hyped sales effort of long established standard products like
coronary stents to keep the narrowed arteries of heart from
collapsing.
Example 2: Dialysis & Transplantation for
ESRD
Globally millions of people undergo various forms of treat-
ment for end-stage renal (kidney) disease (ESRD). Though
renal transplant carries a definitive treatment choice the access
to such treatment is not uniform across the globe. There are
various other forms of renal replacement therapy like haemo-
dialysis and peritoneal dialysis that is offered across the globe.
There are a number of national and international databases that
provide valuable demographic and epidemiologic information
on renal patients since the first report of the European Dialysis
and Transplant Association (EDTA) was published in 1965.
These databanks provide valuable data for researchers to under-
stand various factors impacting the modality of renal replace-
ment therapy. Apart from these databanks there are independent
research reports that try to correlate choice of treatment moda-
lity with various SES factor. Grasmann et al. (Grassmann, Gio-
berge, Moeller, & Brown, 2005) published a research report in
2005, where an attempt was made to correlate financial fac-
tors with modality of treatment. In this study, data from 122
nations were obtained for number of ESRD population who
were into various forms of renal replacement therapy. Ta bl e 1
is reproduced from the study of Grasmann et al. At the end of
2004, some 1,783,000 people globally were undergoing treat-
ment for ESRD. 77% were on dialysis and 23% were with
functioning transplant.
The table presents the fact that more or less 30 - 70 split in
dialysis/transplant patients is usual for North America, Europe
and the Middle East, while much less number of patient live
with a functioning renal transplant in Asia, Latin America and
Africa. Results for Japan are separated from the remainder of
Asia due to the significant differences in the patient care
infrastructure. Analysis of the study population suggested that
economic factors impose restrictions to treatment in countries

in which the GDP per capita is below a limiting value. In 47 of
the 75 countries with the largest ESRD populations, the GDP
per capita per annum is under US $10,000.
It has been found that less than 10% of Indian end-stage re-
nal disease patient receive renal replacement therapy, while up
to 70% of those starting dialysis die or stop treatment, due to
cost, within the first 3 months (Sakhuja, 2003). For end stage
renal disease patient Kidney transplantation promises higher
quality of life. But access to transplant facility is skewed in
favor of the high SES population. Even in developed world,
individuals from socially deprived areas are less likely to re-
ceive a pre-emptive renal transplant, in other words to receive a
kidney transplant prior to commencing dialysis, than those from
affluent class (Roderick, Hollinshead, O’Donoghue, Matthews,
Beard, Parker, & Snook, 2001).
Similar observations on correlation between financial factors
and access to treatment for ESRD were made in a study from
Malayasia. In their study Lim et al. (Lim, Goh, Lim, Zaki, &
Rozina, 2013) confirms distribution of private sector dialysis
facility tend to converge in the economically developed areas
where patients are able to afford its services while the public
sector is expected to do exactly the opposite in accordance with
its social equity mission. It was also noted even the charity
sector’s service distribution seems to more closely resemble the
private sector than the public sector in its allocation of dialysis.
Researchers explained the behavior of charity sector by the
operational constraints of such facility where they need to gen-
erate part of the cost from paying patient to cross subsidize the
indigent ones. While there is rising per capita income by 20 %
(In 1997, 2606 RMB/month, and 3249 RMB/month in 2004),
during this period the number of patient with access to dialysis
treatment rose by 112%. It was found that there was increasing
market share of private & charity sector from earlier combined
46% of 1997, to 2004 level of 65% while the earlier high utili-
zation of government dialysis facility actually registered a 35%
negative growth.

Relationship of prevalence of dialysis patient with percapita income of

The researcher states a clear linear relationship with eco-
nomy of the country and the prevailing number of population
per million on dialysis treatment.
For end stage renal disease patient option of kidney tran-
splantation is the best choice in terms of quality of life and
survival. But across the low and middle income countries such
desirable access level to renal transplantation is not easy. In
most countries transplantation suffers from lack of infrastruc-
ture, and post transplant survival depends critically on the af-
fordability of immunosuppressive drugs, malnutrition and in-
fectious disease, in particular tuberculosis (White, Chadban, Jan,
& Chapman, 2008). Across the globe including the high income
country have certain cultural bias towards benefit of organ do-
nation. In Japan belief about what happens after death and cul-
tural resistance to mutilating the body and the idea of impurity
associated with a dead body mean that only 5% of dialysis pa-
tient enlist for transplantation. Across the Muslim world brain
death has also been a controversial issue leading to debates
among Muslim religious clergy which finally led to a 1996 de-
claration of the Islamic Organization of Medical Sciences al-

to treatment in end stage renal disease we refer to Figure 1 that
has been reproduced from Rotter et al. (Rotter, 2011).

lowing recovery of organs from brain-dead persons. In many
countries or communities cultural bias towards organ donation
may also be an important issue limiting access. As in case of
India, gender inequality limits access to transplantation—For
example, in India, transplants from living, related donors typi-
cally go from female donors to male recipients (Sakhuja & Sud,
2003).
In spite of resource poor environments problem of access to
renal transplant has been circumvented by active policy pre-
scriptions. Costa Rica is one example: in 2002, 78% of its RRT
population had received transplants, among the highest propor-
tion in the world. Costa Rica has doubled the number of pa-
tients on hemodialysis, and has the highest number of kidney
transplants per million population (pmp) in Latin America, with
20.63 transplants pmp in 2000, 27.25 transplants pmp in 2001,
and 24.81 transplants pmp in 2002. This is attributed to a public
health system which, covering 98% of the population, provides
equitable access to RRT; and to high rates of living kidney do-
nation (Cerdas, 2005).
Following a study across 46 countries (population 1.25
billion) Caskey et al. (Caskey, Kramer, Elliott, Stel, Covic, Cu-
sumano, Geue, MacLeod, Zwinderman, Stengel, & Jager, 2011)
concluded that macroeconomic and service organization factors
are considered to be more important, over population age and
health indicators in case of renal replacement therapy.
We shall conclude the case of RRT & Transplant by finally
highlighting the four “A”s of Access. Affordability is definit ely
a driver of technology diffusion in this example as all the stati-
stics show, and we have no further observations. What needs to
be stressed that Affordability alone is not the determinant, in
cases of Japan or the Muslim world adaptation of the trans-
plantation technology has nothing to do with cost of treatment
but is related to a deep rooted belief system, which often guide
many decisions in technology diffusion. Adapting to a particu-
lar technology has cultural elements in it. It is the culture and
religious belief that may determine availability of organ from
dead person, and even if the infrastructure is built benefit of
transplantation will be unutilized for lack of availability of do-
nated organ. Architecture component of the access phenomenon
embeds in itself the care delivery system, the health policy and
the political will of the governmentCostarica is a good ex-
ample to look at where their effective healthcare system in-
cludes 98% of the population to give one of the best chances
with renal replacement therapy comparable to the High income
countries.
The ethical & legal confusion surrounding organ donation,
the case of benefit for the donor and the role of the for profit
third party needs to streamlined in the developing world to
build up a system of equitable access to transplantation.
Providing Healthcare Technology in Resource Poor
Setting
Considering the view that continued progress of healthcare
technology increases inequality by restricting access of techno-
logy to the poorer people one arrives at a difficult juncture to
choose between overall progress of medicine and increasing
disparity of health status of people. To simplifythe choice is
between vertical development in technology driven healthcare
vs reducing inequality of health. Phelan et al (Phelan, Link, &
Tehranifar, 2010) suggest a dual agenda of perusing improve-
ment of healthcare technology and innovation without further
widening the gap of inequality. In their opinion reducing
resource inequality will go a long way to reduced effect of SES
factors over health. The argument is that people use their
knowledge, money, power, prestige, and social connections to
gain a health advantage, and thereby keep the gradient active.
As a matter of policy intervention if we redistribute resources in
the population so as to reduce the degree of resource inequality,
inequalities in health should also decrease. Reducing resource
inequality is at the heart of political agenda of many doctrines
but the outcome of all such beliefs are in itself unequal.
As a corollary to Fundamental cause theory, one may con-
clude that designing policy interventions that effect population
irrespective of resource gradient will reduce health disparity.
Universal programme of immunization, Global eradication pro-
gramme for Small pox can be cited as successful policy inter-
vention which serve entire population with little regard to SES
barrier. More examples can be manufacturing of automobiles
compulsorily with air bags as opposed to an option (as preva-
lent in many developing countries), adding Iodine to edible salt
to prevent thyroid disease, Adding nutrients to edible oils like
(Vitamins) rather than recommending balance diet etc. In each
example, the former solution does not give an advantage to
those with greater resources, because individual resources are
unrelated and irrelevant to benefiting from the i nt er ve nt io n.
The problem of health technology access in poor countries
has been researched by many groups. One notable research by
Reich et al. (Reich & Frost, 2010) , titled “Research Studies for
Promoting Access to Health Technologies in Poor Countries”
comes out with several recommendations for increasing access
to heath technologies in resource poor setting, we shall briefly
discuss their relevance. The study is based on the case histories
of technologies. These observations are made on process of
creating access and the role of applied research studies that are
needed to design an Access Plan. The first observation by Reich
et al is “Developing a safe and effective technology is neces-
sary but not sufficient for ensuring technology access and
health improvement”. Developments in the laboratory has to
find its way through the regulatory & distribution web to the
end users. The technology availability and adoption part is
equally important. The experience with the contraceptive
Norplant is cited as the complexity of the environment of tech-
nology delivery. Norplant was a hormone releasing dermal
implant that is surgically put under ones’ skin was developed by
the Population Council (a non profit body). The technology was
found to be highly efficient in clinical trials, and it demon-
strated a high level of safety. By 1996, more than five million
implants had been inserted worldwide. But Norplant’s contin-
ued use suffered set back in the field. Apart from affordability
the major problems faced were related to health systems capa-
bility to provide expert service of implanting as well as remov-
ing the device. The device suffered adoption hurdles by end
users and finally the success story ended with removal of Nor-
plant from the market in 2002. The innovators and developers
of technology can not expect that developing a good device or
technology will guarantee success. Many problems exist with
access of technology in resource poor setting, one has to under-
stand the limitations of healthcare system’s capability and fac-
tors that control end users acceptance of technology. Develop-
ing world situations are very different from the developed
world where most technologies get designed. Norplant, being a
new implant technology, required both insertion and removal
by a trained provider. The training provided to the care delivery

system of developing world health system was not deep or
comprehensive enough. As a result, many health professionals
were not well trained on removal techniques, and these training
shortfalls led to later difficulties with implant removals. There
were still other problems with Norplant that involved informa-
tion dissemination to users and the issue of counseling to make
it an informed choice.
We are coming to another finding of Reich et al where the
importance of end users preference of technology is illustrated
by a case. The case illustrates the role of end users choice on
diffusion of technology. Using a female condom was seen as a
brilliant idea of empowering women, but enthusiasm for the
device died off soon. It was seen by many women as a large
bulky device to be put inside, they were also prone to slippage
during coital movement. The initial developers of the first gen-
eration of female condoms did not adequately take into account
the perspective of end-users. These problems can be addressed
and supportive counselors might help women with practice
sessions. It was soon discovered that women were not very
comfortable with t he idea of some awkward sessions of practice
to use the condom in a proper & right way. The result of end
users rejection is effected in the sales figure of the product , by
2004, approximately 12.2 million units were sold per year, rep-
resenting only 0.1 - 0.2 per cent of the number of male con-
doms sold worldwide. “A”s a corrective measure, developers
are now taking user input to make new generation product
which are more aesthetically right & inexpensiveto make the
technology more acceptable.
Healthcare technology can also be viewed as a demand sup-
ply equation, while demand for good technology is never a
problem one need to consider at least two supply side issue to
ensure appropriate resolution of the access gap. There is a prob-
lem related to supply side that too can limit access to healthcare
technology. The first supply side problem is forecasting the
needwhich means technology providers or sellers enter a
developing countries market without appropriate knowledge of
market size and quality. This leads to either oversupplyun-
dersupply imbalances and the accessibility of product suffers.
Oversupply to a small region cuts off much needed supply to
another region where demand exists. Forecasting of health need
and a global agency to address these market issues can solve
this problem. Another issue that crops up with medicines or
technology products in developing world is that there being no
effort at health technology assessment, the government gets
confused with too many products competing for the same need.
Most developing world countries can summon limited capacity
to understand the need gap analysis for competing technology.
The world health organization have attempted to address the
issue by providing updated resource in a website to help pro-
curement decisions (“Sources and Prices” document) for ma-
laria products. Reducing information asymmetries, by regularly
dis- seminating updated information to producers and potential
purchasers, can contribute heavily to bridge access gap.
Conclusion
While SES is cited as a blanket term for most important
cause of mortality, from a more inclusive viewpoint to design
policy intervention which does not seem right. Not only SES
factor affect mortality of populations, geography and ethnicity
as well have its claim. SES that includes income, education,
employment, social hierarchy needs to be dissected further to
develop policy intervention as for each component policy might
have to be specifically different.
The most common perspective of redistribution of wealth
amongst citizen, increasing level of income and eliminating
gradient of income might not guarantee health improvement.
This approach by itself is insufficient and what we need to
respect is the problem of access to health care. It is true that
increased level of income will change the mortality pattern or
causes of mortality but it can not be guaranteed that without a
simultaneous level of improvement in care delivery system,
access to facilities big changes will be seen. Redistribution of
income or raising earning will be effective only if health is
determined chiefly by income or by something determined by
income. In preceding sections we have seen apart from issue of
income, healthcare technology usage is shaped by various
socio-cultural and political factors of access. It must be debated
whether continuing to increase income in the poorer people will
progressively increase health outcome or not. Resources like
wealth if accumulated is not allocated only to healthcare needs,
nutrition or sanitationresources also get spent on various
other items that will have no direct positive effect on health.
However, there is a general agreement that low income, lack of
education, social exclusion need to be addressed for improved
healthcare outcome to all. In our opinion these SES factors can
be assigned a higher place, but there still are factors down the
line-healthcare delivery system, technology development and
promotion, technology adoption which also need to be
addressed. If the downstream factors of technology access
remain unchanged, improving upstream socioeconomic factors
will be ineffective.
We take the liberty to quote Nobel Laureate Amartya Sen
(Sen, 2001), to end this discussion. Health equity has many
aspects, and is best seen as a multidimensional concept. It
includes concerns about achievement of health and the
capability to achieve good health, not just the distribution of
healthcare. But it also includes the fairness of processes and
thus must attach importance to non discrimination in the
delivery of healthcare. Furthermore, an adequate engagement
with health equity also requires that the considerations of
health be integrated with broader issues of social justice and
overall equity, paying adequate attention to the versatility of
resources and the diverse reach and impact of different social
arrangements.”
