1 Introduction
Health Information Management (HIM), the profession specifically devoted to health
record science and classification/terminology, continues to play an integral role
in ensuring the proper secondary use of patient data. In the past, the use of patient
data was often limited by the nature of paper-based medical records that served as
information sources for administrative or billing needs and research based on diagnostic
and procedural indices created from the use of diagnostic and procedural/intervention
coding systems.
The healthcare information technology and processing environment is changing at lightning
speed and is only expected to accelerate. For example, the amount of healthcare data
was estimated to be 153 exabytes in 2013, growing exponentially to an estimated 2,314
exabytes by 2020 [[1]]. However, key functionalities such as interoperability and predictive analytics
will not be successful without effective data governance [[1]]. Adding to this is the growth of new sources of health data such as wearable fitness
devices and home monitoring systems. This will result in very large amounts of healthcare
data or big data, defined by Merriam-Webster as “an accumulation of data that is too
large and complex for processing by traditional database management tools.” [[2]]. A recent review by Gu and colleagues identified that big data research in healthcare
has been focused on three areas over the last decade: 1) disease management and epidemiology;
2) technology for data mining and machine learning; and 3) health services such as
personal health devices and electronic health records [[3]]. Shah and Pathak proposed that healthcare may finally be ready for big data, but
they noted that the knowledge generated still has to be translated into practice [[4]].
The changes affecting the format and size of data sources, as well as the development
of tools and methods, lead to foreseeable changes in the practice of HIM to manage
and facilitate the secondary use of patient data. The purpose of this paper is to
describe the results of a literature review and the findings from qualitative interviews
with key opinion leaders in several key focus areas related to issues that are expected
to have a significant impact on the practice of HIM, and hence the profession, over
the next several years. In addition to searching the peer-reviewed literature, the
authors sought unique insights from key opinion leaders in the chosen topics. The
chosen topics are: 1) the increasing need for effective data and information governance;
2) the development of a terminology standards certification; 3) the release and implementation
of the International Classification of Diseases, 11th edition (ICD-11); and 4) the growing role of data analytics. The interviews related
to information governance were conducted both in person and via email. The interviewees
were asked their opinions related to the role between data and information governance;
the similarities and differences between countries, and how to build capacity in workforce
and resources. The face-to-face ICD-11 interviews focused on the ICD-11 features different
countries may use, standards development, parallel processing and other updated considerations,
and any expected needs for mapping. While a myriad of topics could be included, these
four were chosen because each is related to the expanded use of electronic health
records and to the growth in the amount of digital data available for the maintenance
of health and the treatment of diseases across the globe. For example, the practice
of HIM in the U.S. will undergo significant changes with the implementation of value-based
purchasing, but that initiative is not international.
2 Data and Information Governance
2 Data and Information Governance
In conjunction with classification and terminology structures, data and information
governance underpins the appropriate secondary use of patient data [[5], [6]]. In 2016, Gartner defined information governance as “the specification of decision
rights and an accountability framework to ensure appropriate behavior in the valuation,
creation, storage, use, archiving, and deletion of information. It includes the processes,
roles and policies, standards and metrics that ensure the effective and efficient
use of information in enabling an organization to achieve its goals” [[7]]. The key concepts of information governance include records and content management,
information technology (IT) governance, data governance, data security and privacy,
risk management and litigation readiness, regulatory compliance, long-term data preservation,
and business intelligence [[8]]. Information governance should occur with all types of information (clinical and
administrative), all media formats (paper, digital, images, and audio), and all types
of health organizations [[8]]. Health data or information is often sensitive, personal data, and information
that needs to be secure and protected from unauthorized access. Therefore, information
governance is an essential requirement in any health care organization.
IT governance is one aspect of information governance, although these two terms are
often incorrectly used interchangeably. Aspects of IT governance can be said to include
efficient and effective decision-making related to IT, the application of leading
practice when aligning IT endeavors with organizational strategies and objectives,
and the incorporation of data governance principles. Data governance is the “processes
and controls to ensure that information at the data level—raw alphanumeric characters
that the organization is gathering and inputting—is true and accurate, and unique
(not redundant)” [[9]]. The focus of data governance should be on the quality from the original source
(root level) through subsequent uses (secondary use). It is the most basic, rudimentary,
level of information governance and if not undertaken properly, the results will substantially
affect all other levels of information governance. The difference between these three
areas of governance – data, IT and information - are summarized in [Figure 1].
Fig. 1 Information governance, IT governance, and data governance
Health data security and privacy are equally important factors in information governance.
Cohn succinctly distinguishes health information privacy and security as “an individual’s
right to control the acquisition, uses, or disclosures of his or her identifiable
health data … Security … refers to physical, technological, or administrative safeguards
or tools used to protect identifiable health data from unwarranted access or disclosure.”
[[10]]. The increased digitization of information has resulted in many countries revising
privacy legislation to address the issues resulting from the progression of the Internet
of Things.
With the rapid transformation of digital data and information in health care, and
because of the increasing use of mobile technology by a mobile population, there has
been an increased emphasis on information governance in health care in recent years
[[1]]. As an example, the U.S. Veterans Health Administration (VHA) has an Office of
Informatics and Information Governance that leads their efforts to exchange data with
non-VHA caregivers [[11]]. Health reforms, such as an increased focus on value-based payment and shared risk
contracting, have resulted in a greater use of health and administrative data for
service management purposes including planning, management, resourcing, and forecasting.
Therefore, critical processes and tools for data governance support high quality data
collection and maintenance. Adoption of an adequate information governance framework
allows health care organizations to warrant that all health and administrative data
is managed “legally, securely, efficiently, and effectively in order to deliver the
best possible care to people who use health and social care services… [and for organizations]
to ensure that information is used ethically.” [[12]].
An examination of information governance from interviews with HIM key opinion leaders
from five different countries demonstrates the varying levels of global adoption.
Interviewees were selected as they were identified as experts in information governance
in their country through presentations at a national or international level. Deborah
Green, Executive Vice-President and Chief of Innovation for the American Health Information
Management Association (AHIMA), stated that AHIMA sees the use of data and information
as critical to the entire healthcare ecosystem and the health of individuals and populations.
AHIMA developed the Information Governance Adoption Model®, a tool that enables health
care organizations to assess their information governance readiness, that defines
ten organizational competencies of information governance for health care [[13]]. The ten organizational competencies are: strategic alignment, information governance
structure, data governance, Enterprise Information Management (EIM), IT governance,
analytics, privacy and security safeguards, regulatory and legal, awareness and adherence,
and information governance performance. Each organization should assess itself against
these organizational competencies to define its path to maturity in governing its
information. Cameron Barnes, Director of Health Information Services and Information
Governance for Cabrini Health and Education Committee, member of the Health Information
Management Association of Australia (HIMAA), stated that one of the most challenging
aspects of information governance is the sheer breadth of the work required and the
general under-resourcing of the field. Considering the rapid digitization occurring
in health, there is much work required in information governance without the supporting
workforce, leading to risks about data integrity and useability. Barnes concluded
that information governance in health should be viewed as a critical organisational-wide
area and should be resourced to at least commence the building blocks that are required
to establish appropriate frameworks and systems [[14]]. Paul Halliday, Business Intelligence Director Qatar, stated that in order to achieve
successful information governance and the effective utilization of data, organizational
collaboration is key. The data governance framework employed in Qatar includes infrastructure,
roles and responsibilities, standards and monitoring, security, quality improvement,
and monitoring [[15]]. The National Health Service in the United Kingdom also maintains an information
governance toolkit developed by the Health and Social Care Information Centre (HSCIC).
The toolkit allows organizations to assess themselves against the requirements for
management structures and responsibilities, confidentiality and data protection, and
information security. Where an organization’s partial- or non-compliance is revealed,
the organization must undertake appropriate measures in the aim of raising information
governance standards and making cultural changes [[15], [19]].
These information governance initiatives across the globe are testimony to its current
and future importance for the health information management profession. The effective
and efficient secondary use of patient data cannot be separated from foundational
information governance.
3 Terminology Standards and Certification
3 Terminology Standards and Certification
Terminology standards, e.g., Systematized Nomenclature of Medicine -- Clinical Terms
[SNOMED CT], Logical Observation Identifiers Names and Codes [LOINC], provide a foundational
structure in the digital healthcare environment to manage and facilitate the use of
patient data; understanding and appropriately utilizing terminology standards is necessary
to facilitate secondary data use [[16]]. Human resources sector studies, survey data, and a Canadian advisory group validated
that a business need exists in the Canadian health care sector to address the current
lack of workers trained and experienced in the use of clinical terminologies to support
implementation and maintenance of digital health solutions [[17]]. Key stakeholders identified the development of a clinical terminology professional
certification in Canada as a priority to help address this resource gap. The use of
clinical terminologies across the country has grown due to increased investments in
health information technologies [[16], [18]]. In the context of this growing use of clinical terminologies, new and evolving
roles to support e-Health are emerging.
In 2014, the business case for a Terminology Standards Certification was approved
by senior representatives from Canada Health Infoway (Infoway) and the Canadian Health
Information Management Association (CHIMA) Board of Directors. In addition, the Regenstrief
Institute (in charge of the development of LOINC), the International Health Terminology
Standards Development Organization (IHTSDO – responsible for SNOMED-CT), and the Canadian
academic community confirmed their support for a clinical terminology professional
certification in Canada. A multi-stakeholder committee led by CHIMA and Infoway completed
the following initial steps:
-
Development of three terminology standards (TS) role descriptions - Terminology Specialist,
Terminology Technical Specialist, and Terminology Advanced Specialist;
-
Development of a Canadian TS competency framework;
-
Creation of learning content items to support curriculum development.
The committee employed the Global Academic Curricula Competencies for Health Information Professionals [[19]] as the template for the creation of the Canadian Terminology Standards Certification Curricular Competencies [[20]]. The following five domains were developed to support the competency framework
and the creation of learning content items:
-
Foundations of Controlled Terminologies;
-
Management of Controlled Terminologies;
-
Application of Controlled Terminologies;
-
Foundations of Interoperability Standards;
-
Application of Interoperability Standards.
Accreditation standards have been published and the development of a certification
examination will be undertaken in 2017. In November 2016, a new work item proposal
was presented to the International Standards Organization`s Technical Committee 215
– Health Informatics (ISO TC215) Working Group 3 (WG3), tabling to consider the development
of an international standard for workforce roles and capabilities.
Adoption of a standardized process for educating and certifying TS workers will enable
employers to confidently acquire personnel who are able to competently implement and
maintain healthcare terminologies. A skilled TS workforce should support electronic
health record and health information system implementations, thereby decreasing implementation
delays and, ultimately, providing improved patient safety, in Canada and across the
globe.
4 International Classification of Diseases, 11th Edition
4 International Classification of Diseases, 11th Edition
The International Classification of Diseases (ICD) has been used internationally for
more than a century. The 11th edition, ICD-11, represents a new method for combining classification and terminology
to enhance the secondary use of patient data. The discussion within this paper focuses
on the introduction of the new structures that use a foundational component and the
subsets of the foundational component known as linearizations. The original goals for this new edition of ICD were i) to provide an ontological
core developed in partnership with the International Health Terminology Standard Development
Organization (IHTSDO); ii) to create a foundational layer with many entities that
are not mutually exclusive, but have distinct definitions along with multiple relationships;
and iii) to develop derivations of the foundational component known as linearizations,
as mutually exclusive subsets fit for a particular purpose with a single parent within
ICD-11 [[21]]. For example, a specific country may have a linearization specific to its payment
or policy needs. As presented at the 2016 WHO-FIC Revisions Conference in Japan, the
11th revision consists of the foundational layer or component and the linearizations. The primary linearization under development is that for Mortality and Morbidity
Statistics and a Joint Task Force has been appointed to develop this linearization.
The final version of ICD-11 is scheduled on the agenda of the World Health Assembly
in May 2018 [[22]].
The implementation of ICD-11 can positively influence HIM practice through the following
changes. Firstly, the existence of a foundational component with globally agreed upon
definitions will help to ensure comparability and semantic agreement between the different
national derivatives. Secondly, the potential existence of multiple linearizations
allows for linkages and mappings between settings, countries, and possibly between
ICD versions, and other terminological standards. Thirdly, the structure of ICD-11
uses post-coordination for duplicative attributes such as laterality, severity, and
stage to reduce excessive repetition. Many countries considering the adoption of ICD-11
are seeking methods for creating software and tools to maximize the benefit of these
changes. HIM practice and expertise will support the proper use and management of
these systems.
HIM and clinical coding must prepare for a new era with an expanded use of standards
and the system requirements (e.g., terminology mapping) to support ICD-11. Alignment
of classification codes will evolve, most likely by using an automated code-from-text
assignment process versus the current human methods [[23]]. One vision of the future includes clinically computable codes. Clinical computable
coding involves pulling data from all parts of the electronic health record – laboratory
data, medication data, device data, in fact, all machinable or computational data
– rather than from those limited to dictated or recorded reports. Dr. Christopher
Chute, Co-Chair of the World Health Organization ICD-11 Revision Steering Group, terms
this “computable clinical criteria.” [[24]].
Computable clinical criteria are related to the nature of the diagnosis of a disease,
which is now recognized in healthcare as an imperfect science as many diseases have
multiple and varied symptoms. A simple example is food poisoning which could have
one or more of the following signs and symptoms: nausea, vomiting, watery diarrhea,
abdominal pain/cramps, or fever. These are also most of the same signs and symptoms
as dysentery. Diseases have different manifestations in different regions of the world
and may present differently, hence, computable clinical criteria must be clear. Highly
qualified coders or classification specialists will be able to assist in the development
of the algorithms that use computable clinical criteria and to conduct audits to assess
the quality of automated coding assignment.
Vera Dimitropoulos from the Australian National Centre for Classification in Health
shared these thoughts regarding the pending implementation of ICD-11. “Transitioning
between ICD editions and country modifications will require forward planning, perhaps
parallel running, of the two classifications at the same time (e.g. maintaining the
current classification whilst developing the new classification to ensure it is fit
for purpose to suit clinical practice). Considerable lead time will be required from
an IT infrastructure point of view to support the new classification structure (e.g.
patient administration systems, morbidity coding tool vendors, mortality coding systems).
Mapping is vital to ensure consistency with time series analysis and development of
case-mix/activity based funding systems (groupers). Time and motion studies (dual
coding studies – current vs. new) will be needed to determine the need of any increase
in workforce (especially at the outset).” [[25]]. While the foundational coding classification and bio-medical science education
remain relevant for ICD-11, education and training in more technical skills such as
computational thinking will be required. Consistency in the secondary use of patient
data means that terminology and classification standards must continue to evolve.
5 Data Analytics and Health Information Management
5 Data Analytics and Health Information Management
Health record science and health information management are evolving to address the
changing secondary use of patient data, introducing concepts from data science. The
data scientist is an evolution of the data analyst/business analyst role and can be
defined as one who is involved in the “acquisition and interpretation of data for
business intelligence functions within the organization” [[26]]. The data scientist analyzes and interprets data into information and seeks new
innovative sources of information from the available data. Data stewardship is primarily
responsible for information and data governance in health care, while data analysis
uses data and information for predictive modeling to inform clinical care and as a
management tool for health care performance management [[15]].
Digital transformation will have a large impact on operational processes within performance
management [[27]]. Data analytics is an important part of performance management as it allows managers
to make decisions on real information rather than on historical performance or assumptions.
With the forecasted explosion in data over the next three years [[28]], health service managers are looking for ways to invest in improved data collection
and build a new workforce to support the collection of data and analysis for performance
management [[1]].
Data is forecast to become the biggest growth area in health due to digital health
transformation [[29], [30]]. It will become the tool to drive policy change for an efficient and effective
healthcare system [[31]] and interconnect providers and organizations to improve the monitoring of health
outcomes and service quality. This explosion of available data brings a range of technical,
governance, and compliance issues and as a consequence, there will be a greater need
for health information management to incorporate data science methods to use and manage
healthcare data over the next decade [[1], [32]].
6 Conclusions
The digital health transformation will require the HIM profession to evolve its core
skill set and redefine its role in health, with Kloss acknowledging “HIM has a vital
role to play to safely and effectively leverage health IT to benefit patients and
improve system performance.” [[33]].
The American Health Information Management Association (AHIMA) warns that “while the
EHR hasn’t changed the need or demand for HIM professionals’ skills, it has dramatically
changed the way those skills are applied and has accelerated the need for professionals
to add new electronic-based abilities. ... [A] failure to adapt ... could lead to
obsolescence, or at least provide an opportunity for non-HIM professionals to move
into traditional and emerging HIM roles and take their place.” [[34]].
The results of a 2015 AHIMA survey of Health Information Managers identified an anticipated
decreased need for skills and competencies in coding and records management and an
increased need for skills in the areas of leadership, data, and informatics over the
next decade. In particular, respondents identified that the areas of data analytics/mining,
informatics, and information governance will see the greatest growth in the field
of HIM [[35]]. In 2015, Gibson, Abrams, and Crook identified in Canada the impact of emerging
trends on Health Information Management, finding Health Information Managers are increasingly
moving to roles such as data management and health information analysts, privacy and
security officers, workflow analysts, project and program managers, and educators
or trainers [[36]]. Most recently, the Department of Labor in the U.S. has recommended new Occupational
Classification codes giving further support to the current and continuing evolution
[[37]]. In a rapidly transforming healthcare system, the HIM profession needs to obtain
and position itself as possessing essential, executive level set of functions and
skills to remain relevant within health care organizations [[33]].
This survey paper has provided an overview on four key areas impacted by the evolution
of electronically available patient data and the ongoing development of standards,
structures, and terminologies. Each of these areas is linked to the secondary use
of patient data and requires that health information management practices evolve to
adapt to and facilitate the progress of emerging technologies. Challenges exist for
HIM professionals to ensure they possess the relevant and applicable education, skills,
and knowledge to match the requirements of the healthcare industry; and for the education
system to produce highly educated HIM practitioners. The information and wisdom gleaned
from the effective secondary use of patient data is needed as nations seek to improve
their healthcare delivery systems and the health of their citizens.
