<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b>Background:</span><span lang=EN-NZ></b>
Due to the accelerating development of technology and the globalisation
of HIS, it is becoming increasingly important for health professionals
to implement and maintain security measures for their HIS.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b>Objective:</span><span lang=EN-NZ></b>
This research compares, British, American and New Zealand HIS security
standards and researches minimum-security requirements available to compare
this with the results of a survey in the NZ Residential Care Industry.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b>Methods</span><span lang=EN-NZ></b>:
The research is a cross-sectional study that evaluates and compares descriptive
qualitative data derived from a population sample by means of a questionnaire,
and literature research with descriptive qualitative data on minimum-security
requirements from other studies, established standards or legislation and
literature.&nbsp;</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">A survey
is designed and conducted in the facilities of a large residential (elderly)
care provider in New Zealand. It is targeted to Managers, Care Managers,
Registered Nurses and Administrators. The questionnaire investigates how
HIS security in the residential care industry compares.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b>Results:</span><span lang=EN-NZ></b>
The results of the literature search failed to return minimum-security
requirements for HIS for any of the countries targeted in the research.
The survey had a 58% return rate, this equates to a sample population of
28. Compliance with minimum-security requirements was below 50%. Statistics
and graphs were designed and calculated in MSExcel with PHStat add-inn.</font></span></div>


<p class="MsoNormal"><span lang=EN-NZ><b><font color="#000000">Conclusions:&nbsp;</font></b></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">Minimum-security
requirements establish an important basis for consistency in developing
health companies HIS security policies and procedures. Continuation of
inconsistency in security procedures jeopardises the quality of patient
care, the HIS and increases risk of litigation for health professionals
and organizations. The minimum-security requirements in the NZ residential
care industry are severely compromised and the risk of security breaches
and data loss is high. Minimum-security requirements for HIS in the targeted
countries are not available.</font></span>

<h3>
<span lang=EN-NZ><font color="#000000">Introduction</font></span></h3>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">Since the
1990’s the use of computerised HIS in New Zealand and other first world
countries has developed at an accelerating pace. In conjunction with this
the <i>“concerns about privacy transcend the health care setting. Americans
believe that their privacy rights are not adequately protected”</i> [<span style='color:#FF6600'>2</span>].
These concerns were reflected in other countries including New Zealand.
The New Zealand government developed the Health Information Privacy Code
1994&nbsp; (http://www.knowledge-basket.co.nz/privacy/comply/HIPCWWW.pdf)
to ensure privacy of health information.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">It is becoming
increasingly difficult for the lawmakers to stay in line with new developments
in our ever-accelerating technology. Privacy and security requirements
are no exception.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><i>“With
the advance of technology have come a variety of challenges to our privacy.
It’s not that the Internet causes loss of privacy-but it has made us more
aware of the issues surrounding privacy. The complexities involved in maintaining
our privacy and security in a world where information is increasingly public
can be daunting.”</span><span 
lang=EN-NZ></i> [<span style='color:#FF6600'>3</span>].
Compounding this problem is the globalisation of information and the lack
of global legislation to protect the privacy of our health information,
<i>“it
is easy to understand why some kinds of information should be accorded
special status and legal protection based on their sensitivity and the
great damage that can occur from unconsented disclosure.”</i>[<span style='color:#FF6600'>4</span>].
The protection of our health information is imperative to maintaining the
individual’s privacy.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><i>“The essence
of security is to protect the availability, integrity and confidentiality
of data and systems”</span><span 
lang=EN-NZ></i>[<span style='color:#FF6600'>5</span>].
The lack of security has the potential to put: the patient, the clinician,
the system and the organization at risk, the reason is that medical organizations
<i>“tend
to focus our greatest emphasis on patient care. But once you understand
how profoundly a lack of IT security can effect your organization, right
down to the clinical level, you come to appreciate the importance of it.”</i>[<span 
style='color:#FF6600'>6</span>]&nbsp;</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">Unfortunately
<i>“most
hospitals and health systems don’t understand how much at risk they are”</i>
[<span 
style='color:#FF6600'>7</span>].&nbsp;</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">Global security
principles for health information systems do not exist because nobody owns
or regulates the Internet. Most countries developed their own security
legislation and principles. It is concerning that HIS have been in generalised
use since the early 1980’s and most legislation and security guidelines
originate from the late 1990’s.&nbsp;</font></span></div>


<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">HIS risk assessment
and implementation of security measures to ensure a secure, private and
dynamic HIS is possibly one of the major tasks that the NZ Health Service
and other countries need to have to deal with.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b><i>First:</span><span 
lang=EN-NZ></span><span lang=EN-NZ></i></b>The
human factor where required to operate HIS system. Any system is only as
secure as the weakest link and no system is fully secure. Staff ‘s major
concern is patient care; this in itself provides a heavy workload. Many
people think that the greatest security concern for our health information
is unauthorised on line access by “hackers”, this is possibly due to the
front page news it makes and the embarrassment it causes when a hacker
gains access.&nbsp;</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">However most
organizations largest concern is internal, <i>“an angry employee or a simple
mistake is much more likely to occur than an outside hack and is tremendously
harder to stop”</i> [<span 
style='color:#FF6600'>14</span>], lack of compliance
with security policies due to other work pressures and /or lack of understanding
and education would be the next largest concern.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b><i>Second:</span><span 
lang=EN-NZ></i></b>
There is a lack of global HIS security standards and there is no minimum-security
requirement that could be reflected in consistent policies and procedures
throughout the health care industry.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b><i>Third:&nbsp;</span><span 
lang=EN-NZ></i></b>The
accelerating speed of development of new technology. Technology is developing
fast than the tool to secure the HIS. This is an ongoing concern that will
continue to exist. There are a number of countermeasures available to protect
the HIS. The NZHIS security publications describes that some of these measures

and there is no tangible evidence that they are effective. Most countries
have problems stretching the health dollar to meet requirements. HIS security

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><b><i>Fifth:</span><span

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">To allow
different health service software applications to communicate with each
other, Health Level 7 (HL7) protocol was developed as a standard for health
networks this has been adopted by New Zealand. The HL7 protocol managers
have appointed a group that will focus on secure transactions and Internet
security<i>. “The group will focus on the use of HL7 in communications
environments where there is a need for authentication, encryption, non-repudiation,

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">To establish
the degree of risk encountered by individuals and/or the health industry
is difficult<i>. “The Internet is unlike anything humankind has ever experienced.

the creativity of its users. As such, it defies many traditional roles
of government and rules of order. This openness is its greatest strength
and also its most defining weakness.</i>”[<span 
style='color:red'>17</span>].
There is a multitude of factors which impact on the degree of risk and
the Internet is only one aspect of these. Some other aspects are Access,
System integrity, Date integrity and availability and Confidentiality/Privacy.
It would be an impossible task to eliminate all the risks, paper based
HIS have incurred a degree of risk as well. It is beneficial to minimise
these risks factors because the cost both social and financial can be high.&nbsp;</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">For example
if a person’s health information would be available to insurances or employers,
certain privileges might be denied (justified or not), or a disgruntled

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">First question
was to establish if staff was eligible to take part in the survey, to reduce
redundant data. Staff who were not eligible because they did not use computerised
HIS, were asked to complete demographic data only.18 of the questions had
yes/no, or yes/no/don’t know answers and there were 8 other security questions.
The survey finished with 4 demographic questions, which would establish
the occupation, gender, age group and length of employment.</font></span></div>

95% (to allow a 5% margin of error) of the questions 2.1 to 7.3 were answered

<span lang=EN-NZ><font color="#000000">Results</font></span></h3>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">The survey
was designed in Infopoll Designer [<span style='color:red'>20</span>] and
transferred to a MSWord format to make this suitable for a mail out and
targeted to Registered Nurses (RN), Administrators and Managers. After
approval was obtained from the general manager, 48 Questionnaires were
distributed by mail and there was a 58% return rate.&nbsp;</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">82 % of the
returned surveys were staff that used health information systems. 18% of
this category of staff did not. It is difficult to establish if this is
a true reflection of the total population of staff. There might be bias
in the fact that staff that do not use HIS are less likely to return the
research survey. This 18 % was made up of 1 RN and 4 managers.</font></span></div>

<div class="MsoHeader" style="tab-stops:36.0pt"><span lang=EN-NZ><font color="#000000">The
acceptable mean would be around 95&nbsp;</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">The survey
mean was 41.95, with a standard deviation of 28.76. This means that the
majority of preferred answers are within 28.76 around the mean. The standard
error is 6.13 with a 95 % confidence level.</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">I am unable
to compare statistics in regard to compliance with minimum-security standards
in the NZ health industry because they do not exist. There is only advisory
material available which does not give a minimum standard.&nbsp;</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">100% of the
HIS computers was found to be equipped with a virus screener. There appears
to be uncertainty about who is responsible to update the virus screener,
35 % of the surveyed population said they were not responsible and 26 %
didn’t know.&nbsp;</font></span></div>


<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">17% of the
population updated and scanned their HIS computer fortnightly which is
considered insufficient, due to the increasing speed of new viruses being
developed, a minimum of a weekly update and scan is advisable. In addition
to this 26% is not aware if the virus screener is set on automatic screening
of all incoming information.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">Control of
access to the HIS computer is an essential part of minimum-security standards.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">The survey
results show that 78 % of the surveyed population share HIS computers with
other staff, 70% share passwords and 48% know passwords of other staff.
52% of the computers carry only one password to access the computers and
35% carry no password. The majority of passwords are relatively uncomplicated
(57% consists of letters only and 17% is made up of letters and numbers).
This makes unauthorised access easy, in addition there are no audit trails
and 57% of the staff use networked computers. This places the system at
high risk of undetected unauthorised computer and network access.&nbsp;</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">The risk of
unauthorised access is increased; only 30% of the survey results indicate
that the computers carry a screen saver password.&nbsp;</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">For the computers
who do carry passwords access is at risk. Access via an administrator’s
password is minimal (only 22%) in addition, only 26% of the passwords are
stored in a safe or comparable safe storage.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">Protection
of what is considered sensitive information is severely challenged, only
48% is password protected and only 4% of the files are encrypted or password
protected when Emailed, digital signatures are not used which make authentication
of the sender impossible and interception easy.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">78% of the
surveyed staff backup their HIS computer, unfortunately 17 % does this
less than fortnightly. This equates to only 61% of the surveyed staff correctly
backup their HIS information, therefore the risk of information loss is
potentially high. A preset cyclical backup would be the preferred backup
method.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">52% of the
survey population has received education in regard to computer security,
but the level and the type of education is not known.</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">There were
no obvious correlations between the demographic and the other survey data</font></span>

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">In using the
preferred answers the overall mean of the survey is 41.9%. This translates
in 41.9% of the survey population returning the preferred answer. To maintain
an acceptable minimum-security standard this figure should be 95% (this
allows for a 5% margin of confidence), in all the surveyed areas (see Tables
2 -10.).</font></span>

to any attempt to secure an information system is that the users are aware
of and follow appropriate routines and procedures. It will remain beyond
the realms of practical reality to develop preventive strategies that make
it impossible for user to breach security, and it is the authorised users
of the system who are generally the weakest link in the security system”</span><span lang=EN-NZ></i>[<span

Some <i>“clinical users consider computerisation offers significant advantages
in terms of security and confidentiality. Provided security systems are
activated and used properly, computerised notes are more secure than paper
notes; likewise e-mail is more secure than for example hard copy facsimiles.
Most practices were careful about this issue, but in others the attitude
to security was more ‘loose’, with clerical staff not only accessing the
notes, but being responsible for writing the patient summaries”</i>[<span style='color:#FF6600'>22</span>].</font></span></div>

<div class="MsoNormal"><span lang=EN-NZ><font color="#000000">It is surprising
to find that minimum-security requirements have not been established in
New Zealand and available security standards are open to interpretation
of its users. This potentially creates concerns for the security of the
entire New Zealand HIS. <i>“A health-data technical security policy should
be adopted by each Health Care Establishment site”</i>[<span style='color:red'>23</span>]</font></span></div>

<div class="MsoNormal"><span style='mso-ansi-language:EN-US'><font color="#000000">Most

<p class="MsoNormal"><span lang=EN-NZ><font color="#000000">Minimum-security

The degree of risk encountered by the health company is high, this does
not reflect in risk for the NZ Health Intranet because the Residential
Care Provider is not connected.</font></span>
