Health Technology Assessment:
.

INTRODUCTION
Health technology assessment (HTA) can be defined as a multidisciplinary activity
that systematically investigates and examines the safety, clinical efficacy cost-
effectiveness, organizational implications, and social consequences/repercussions,
ethical as well as legal considerations of the application of a health technology. The
technology is usually a drug, medical device or a surgical/clinical procedure
(Turchetti, Spadoni and Geisler, 2010). The current research study will focus on
understanding how healthcare purchasers, providers, industry and patients have
influenced the assessment of health technology all over the world.
ABOUT HEALTH TECHNOLOGY ASSESSMENT (HTA)
Within the United Kingdom healthcare settings the health technology assessment
can be broadly divided into two areas;
 Clinical Effectiveness.
 Cost-Effectiveness (Kaltenthaler and et.al., 2006).
Health care purchaser can be defined as an individual or organization which is
involved in the acquisition of the healthcare services through procurement from
hospital trusts; primary care trusts (PCTs) or independent private hospitals. It further
involves in making provisions for the deliverance of these healthcare services to the
users and patients and a subsequent monitoring for evaluations and assessments of
outcomes and implementation in improvements programs (Tynkkynen, Keskimäki
and Lehto, 2013). This is called healthcare commissioning. In UK healthcare
settings, this is undertaken by the clinical commissioning groups (CCGs).
Commissioning is the set of inter-linked activities required to assess the healthcare
needs of a population, specifying the services required to meet those needs within a
strategic framework. This is further followed by securing those services, monitoring
and evaluating the outcomes obtained through the provision of those services
(Clarke and et.al., 2015).
The process of commissioning has a significant impact on the healthcare technology
assessment internationally. Commissioning is a collaborative exercise between the
inter-dependent and inter-twined parties and entities, who invest the available
resources of money, talent, and commitments to re-structure services and networks.
This is done in order to meet the perceived and anticipated needs of the population
under consideration and consequently bring about a significant improvement in the
patients’ and populations’ health and wellbeing (Sun and Schoelles, 2013).
In order to gain beneficial outcomes in regards to health technology assessment and
to assess the significance of resource planning and prioritization a study carried out
by (K-Claxton et al, University of York ,Centre for Health economics), tried to

investigate its importance. This pilot study analyzed the significance of applying the
decision analysis and value of information analysis (DA-VOI) in prioritization of the
research strategies in health technology assessment. The specific objective of the
pilot study was to identify the most appropriate ways to extend the use of these
methods within the program prioritisation processes.
The conclusions which have been drawn from this study make recommendations for
practical considerations to be devised about as how to implement such methods into
priority-setting processes and how to gain the best outcomes in the research in
health technology assessment. This is in regards to resource planning, allocation
and commissioning into the research process in HTA.
The study made recommendations that there is a need for an analytical frame-work
that can address the question of whether additional resources would be better be
devoted to additional research or interventions for changing the prevailing clinical
practices.
GP-commissioning is a consequence of purchaser-provider split in which GPs are
the purchasers and hospitals are providers of healthcare. But this split is just artificial
and does not exist in its realm with explicitness. Rather it is tremendously indefinite
and indistinct with colossal vagueness as the GPs are essentially providing
healthcare as much the hospitals-providers do provide. The purchaser-provider split
has created a scenario of competing financial interests and considerations between
the GP-purchasers and the hospital-providers. Due to these competing financial
implications and considerations, GPs are doing the least referring and referrals to
hospitals so that their financial interests are not jeopardized. The purchaser-provider
split is tremendously detrimental to patients as they are stuck between them.
Moreover, they are having lesser and lesser communications and mutual
collaborations due to their competing financial interests and considerations
(Reference; A Better NHS).
A research study carried out at University of Calgary, Canada, by Marie-Pierre-
Gagnon et al sought to understand the complex factors affecting the uptake of HTAs
recommendations and health technologies into the practices and its effects in the
formulation of the decision making and the health technologies implementations in
the GP practices and its reciprocal inter-dependence. The research used a
multidimensional framework to investigate the significance of existing collaborations
and communications between practices and HTAs agencies and its impact upon
integration of the health technology assessments and health technologies into
practice.
This study presents a comprehensive framework to understand the complex
dynamics which affects the processes involved in health technologies integration and
adoption into organizational and professional practices. The research study suggests
some avenues to promote integration of HTAs recommendations into practices. This

is followed by introduction and integration of scientific evidence to be implemented
into healthcare systems as an approved healthcare technology.
The book written by (Richard S. Dick et all ) elaborate in detail the implementation
and integration of computer-based patients record systems (CPRs) into the practices
and describes how the clinical practices have influenced the adoption of this newer
innovative technologies into the medical practices in (USA).
This book describes the myriadness of factors that drove the urge for adopting newer
healthcare technologies into medical care practices to the management and
amelioration of the escalating costs of the medical care. This was done so that
reforms will be brought out to amelioration and attenuation of the extra costs of
healthcare and its substantial burden and heftiness upon the healthcare services.
This cannot be achieved if these newer healthcare technologies would have not
been introduced into the healthcare through innovation and technological
advancements. So the computer-based patients records (CPRs) were introduced to
accomplish this goal.
This also sought to elaborate on evolving primary care provider’s roles and its
concomitant introduction with integrated computer-based patient’s records (CPRs)
systems. One of the major goals of the managed care was to provide most of the
care outside hospitals as per ease of patients but the impatient and outpatients
setting differ substantially. Therefore there was a dire need to understand
technological requirements of physicians working in ambulatory care provision
facilities and steps were taken for upgrading information systems to increase the
efficiency and effectiveness of clinical practice throughout the continuum.
Another fundamental concept that heightens the need for the CPR systems was of
integrated delivery systems (IDS) which composed of healthcare providers, services
providers and facilities organized to provide a continuum of healthcare services to a
defined population under consideration.
For a prompt and a smooth operation of the IDS systems, there is requirement of
efficient information systems in place which captures, collates, analyzes stores and
manages clinical data at all different sites where care is provided. Technological
advancements and the developments in computer processing powers have
revolutionized and influenced drastically the adoption and integration of healthcare
technologies into healthcare.
Another very significant concept within the domain of the HTAs is, influenced by
purchasers’ and providers’ of healthcare services.. Despite the huge significance in
governing the direction of innovation processes in healthcare delivery and
embeddings of healthcare technologies into healthcare practices, the HTAs and its
procedural specifications as in regards to practices that are in vogue , are still

surrounded by vagueness and indistinctiveness. Practical steps are taken and
measures are made to implement the evaluation processes as to the implications of
the conduct of the HTAs. References (Maggie Mort/Carl May et al).
Consensus methods for the medical and health services research as a concept was
introduced by (Jeremy Jones / Duncan Hunter). It describes that healthcare
providers are faced with huge dilemma of trying to make decisions in the scenarios
where they face an issue of insufficient information and scientific evidence.
Conversly, there is usually a substantial amount of contradicting evidence in
pertinence to the topic under the scientific interrogation and investigation. Statistical
methods and methodologies have been devised and developed to summarize and
resolve the inconsistencies in such study findings and research conclusions.
The Impact of Pharmaceutical industry on HTAs;
Taking into consideration the impact and influences of the pharmaceutical industry
on the health technology assessments and research it can be said that, the
pharmaceutical industry is a very significant stakeholder, contributor and the
determinant of the medical research and the health services and health technology
assessments research and its consequential approval as a result of this research . If
you prescribe their drugs and medicines the pharmaceutical company and the
pharmaceutical industry is heavily interested in you and are ready to invest a
staggering sum of money trying influencing you.
Pharmaceutical industries invest heavily on their medical reps (representatives) for
the purpose of marketing and the promotion of their products which may be
medicines or other medical devices , instruments and equipments .In medical
research, the concept of the surrogate end point measurement is also quite
prevalent which can be defined as a secondary outcome variable. It is measured to
reflect upon the variances in the outcome variable of some other more toxic agent or
which may not be very conveniently measureable. So the surrogate end point
variables are measured and taken account of as proxy-outcome end point variables
for other variables for the reason of convenience and ease. One such surrogate end
point variable which is used in medical clinical practice and research, is HbA1C
which is used to assess the glucose control in the diabetics.
Another very discouraging and materialistically competitive trend which may be
present on behalf of the pharmaceutical industries on the influences on the HTAs is
the demonstration of a very non-professional and irresponsible behavior in the
medical research and the health technology assessments research is the money-
making approach and the financial considerations are given the priority over the
patients’ safety in regards to the association of the adverse effects with a drug or a
medical device. One such an example is of the rofecoxib drug which got approval for
the market access without proper considerations for the full profile of the

cardiovascular side effects of the drug. This drug was associated with a substantially
higher risk of cardiovascular risk and associated risk of strokes but the drug data
profile that was submitted to the Food and Drug administration for the purpose of
evaluation and approval, was incomplete, despite that, it was given approval and
market access in spite of these incompleteness and inconsistencies in the drug
industry reports.
This kind of industry behavior with a concomitant irresponsible attitude of the policy
maker institutions, giving approval to the health technologies without a proper
assessments report submissions and a stringent approval and a rigorous
recommendations systems , is to the detrimental of the whole system of the health
technology assessments and approvals , it is simultaneously , going to have a very
untoward and deleterious influence on the whole healthcare delivery systems. The
whole paradigm of principles have to be formulated and a myriad of fundamental
changes have to be brought about to inject fairness into the system of the approval
processes of the health care technologies.
Pharmaceutical industries also play a pivotal role in the developments and the
promotion of the medical research through massive investments of money resources
and talents. The industries compete in the field of research and innovation to bring
out newer and innovative medical drugs and medical devices and technologies into
the market to the promotion of the medical healthcare and care improvements for
patients and other healthcare users. The pharmaceutical industries invest heavily on
the hiring of the services of medical experts and medical scientists to the promotion
and developments of the health care technologies. This way the pharmaceutical
industries have an inevitably indispensable and imperative role in the improvements
of the healthcare medical research and health technologies innovations and
developments. Without the collaborations and the heavy investments of these
industries into the field of the medical research, it would have had been essentially
impossible to achieve the target of establishment of an excellent healthcare system.
Similarly , the patients also have a very important ,undeniable influence on the health
care technology, as it is the patients, for whom, the whole system is being designed
and formulated and the best results are desired to be obtained for the patients. That
is the reason that the patients are considered an inevitably essential component of
the health care system and their influences are of paramount significance in the
determination of the medical research in the healthcare systems.
A mention, of the computer-based health/patients records (CPRs) can be made at
this time due to its relevance and significance as a very important health technology
that has been introduced and implemented into the healthcare systems to the
massive improvements that have been achieved as a consequence of it. These
computer-based patients records systems have been developed due to the
influences and impacts of the requirements and necessities of the patients upon the
health care technologies.

There has to be a continuum of struggle to cope with continuously evolving new
needs of the patient and as an influence and a consequence, an endeavor has to be
made to the invention and innovation of the ways these new needs can be met of the
patients.
So , at the end , whilst winding up the discussion on the subject of significance of the
influences of the purchasers ,providers ,industry and the patients ,we can draw the
conclusion that all these factors essentially are intertwined and interlinked and there
is the existence of slid , robust scientific research data that underpin this
fundamental fact , of the significance of these all in the processes HTAs.
