The challenge of implementing health information systems : a case study in Charlotte Maxeke Johannesburg Academic HospitalSerobatse, Moilwa Denton 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: This thesis investigates the complexities involved in Health Information Systems. The focus
is on the factors of a) efficiency and b) usability. A case study is made of a recently
implemented system in Charlotte Maxeke Johannesburg Academic hospital. The first
objective of the research was to gain a deeper understanding of the complexities of Health
Information Systems, and secondly to evaluate the situation at Charlotte Maxeke
Johannesburg Academic Hospital.
In Chapter 1 a detailed introduction of the thesis is offered. This includes, explaining what
triggered the research, the objective of the research and the methodology used to conduct the
research.
In Chapter 2 the focus is on a literature review of Health Information Systems, system
fundamentals and planning and implementation. It is clear that without a methodology,
systems development becomes haphazard and subsequently a risky and expensive
undertaking. While change is pervasive, introducing operational efficiencies sometimes may
necessitate reviewing of information systems and business strategy, knowledge management
and process orientation.
In Chapter 3 the issue of usability is investigated. Several healthcare institutions have
implemented information systems but evaluations of the usability of these systems are still
under debate. For purposes of this research an evaluation method for system usability and
survey questionnaires were developed.
In Chapter 4 the case study of Charlotte Maxeke Johannesburg Academic Hospital is
reported. The chapter also describes the data collection design, research limitations and
delimitations, survey findings and interpretations.
In Chapter 5 the implications and applications of Health Information Systems are discussed.
After analysis of the survey results, it appears that the impact and benefits of the new Health
Information System are only positive or realized in the patient administration division. The
rest of the health professionals continue to manually capture clinical notes and other
management information on pieces of papers, spread sheets and word documents.
The thesis comes to the conclusion that despite widespread use of technology in other sectors,
clinicians in hospitals do not use implemented automated systems. Implementation of
systems is complex and problems associated with usability are not resolved and that
traditional systems implementation methodologies may not apply. / AFRIKAANSE OPSOMMING: Die tesis ondersoek die faktore wat Gesondheidstelsels (HIC) ingewikkeld maak. Die fokus is
op a) doeltreffendheid, en b) bruikbaarheid (uit gebruikersoogpunt). ‘n Gevallestudie word
gemaak van ‘n stelsel wat onlangs by Chalotte Maxeke Johannesburg Akakdemiese Hospitaal
in gebruik geneem is. Die eerste doelwit van die ondersoek was om die
ingewikkeldheidsgraad van sodanige stelsels te probeer bepaal, en tweedens om die situasie
in die hospitaal self te evalueer.
In hoofstauk 1 word die agtergond en aanleiding tot die ondersoek uiteengesite, woel as die
metodologiese keuses wat gemaak is.
Hoofstuk 2 bied ‘n oorsig oor relevante literatuur ten ospigte van HIC. Dit is duidelik
stlselontwikkeling riskant, onnodig duur en koersloos is as dit sonder ‘n duidelike
metodologie geïmplementeer word. Verandering vind voortdurend plaas en die
implementering van oprasionele doeltreffendheid mag vernadering in besigheidstrategie,
informasiestelsels, kennisbestuur en processoriëntasie noodsaaklik maak.
In hoofstuk 3 word bruikbaarheid ondersoek. Verskeie mediese instellings het soortgelyke
stelsels in gebruik geneem, maar die bruikbaarheid daarvan is steeds onseker. Vir die
doeleindes van hierdie tesis is ‘n eie evaluasiemetode ontwikkel en ‘n vraelys op grond
daarvan opgestel.
Hoofstuk 4 rapporteer die gevallestudie in Charlotte Maxeke Johannesburg Akademiese
Horspitaal hospital. Datakolleksie, navorsingsafbakening en – beperkinge, sowel as
vraelysresultate word aangebied.
Hoofstuk 5 bespreek die implikasies en toepassings van HIC. Dit blyk dat die voordele van
die stelsel slegs deur die pasiëntadministrasieafdeling geniet word. Alle ander afdeling gaan
steeds voort met papiergebaseerde inligtingstelsels, aangevaul deur ad hoc gebruik van Excel
en woordprossering.
Die tesis kom tot die gevolgtrekking dat kliniese personeel avers is teen die gebruik van
geoutomatiseerde informasiestelsels.

Prioritising data quality challenges in electronic healthcare systems in South AfricaBotha, Marna 10 1900 (has links)
Data quality is one of many challenges experienced in electronic healthcare (e-health) services in South Africa. The collection of data with substandard data quality leads to inappropriate information for health and management purposes. Evidence of challenges with regard to data quality in e-health systems led to the purpose of this study, namely to prioritise data quality challenges experienced by data users of e-health systems in South Africa. The study followed a sequential QUAL-quan mixed method research design to realise the research purpose. After carrying out a literature review on the background of e-health and the current status of research on data quality challenges, a qualitative study was conducted to verify and extend the identified possible e-health data quality challenges. A quantitative study to prioritise data quality challenges experienced by data users of e-health systems followed. Data users of e-health systems in South Africa served as the unit of analysis in the study. The data collection process included interviews with four data quality experts to verify and extend the possible e-health data quality challenges identified from literature. This was followed by a survey targeting 100 data users of e-health systems in South Africa for which 82 responses were received.
A prioritised list of e-health data quality challenges has been compiled from the research results. This list can assist data users of e-health systems in South Africa to improve the quality of data in those systems. The most important e-health data quality challenge is a lack of training for e-health systems data users. The prioritised list of e-health data quality challenges allowed for evidence-based recommendations which can assist health institutions in South Africa to ensure future data quality in e-health systems. / Computing / M.

Designing a real-time data streaming technique for enhancing the effectiveness of destination selectionGithinji, Stanley Muturi 08 1900 (has links)
The effectiveness of tour destination selection is dependent on pre-visit information
sources. As competition increases in the tourism industry, destination
organisations need to improve current destination selection processes. Research
on current processes indicate that information sources accessed by potential
tourists when making travel decisions may not be a true reflection of what the
destination is offering. Any negative difference between perceived images during
pre-visit and real images during the actual visit may result in poor destination
reputation and dissatisfied customers.
This research addresses this gap by improving the process of destination selection
using a real-time data streaming mediation technique as an additional pre-visit
information source. The researcher adopted a social-technologist research
paradigm and a design-science approach. The research process was executed in
three phases; the first phase focused on gathering knowledge on destination
selection and pre-visit information sources. The findings in Phase 1 were used in
Phase 2 to develop and test the performance of a prototype. Phase 3 involved the
evaluation of the prototype tool in a real-world setting.
One of the main outcomes of this research is the development of a destination
selection framework using real-time data streaming mediation and a tool
(http://www.tourcamportal.com) as proof of concept. This research has shown that
real-time images are valuable pre-visit information sources when making travel
decisions. Real-time images authenticate destination attractions, provide real-time
availability of destinations, reduce speculations on destination attractions, and
provide actual representations of destinations. The findings of this study contribute
the body of knowledge and practice in the tourism sector and provide new areas
for further research. / Computing / D. Phil. (Information Systems)

Engendering the meaningful use of electronic medical records: a South African perspectiveChipfumbu, Colletor Tendeukai January 2016 (has links)
Theoretically, the use of Electronic Medical Records (EMRs) holds promise of numerous benefits in healthcare provision, including improvement in continuity of care, quality of care and safety. However, in practice, there is evidence that the adoption of electronic medical records has been slow and where adopted, often lacks meaningful use. Thus there is a clear dichotomy between the ambitions for EMR use and the reality of EMR implementation. In the USA, a legislative approach was taken to turn around the situation. Other countries such as Canada and European countries have followed suit (in their own way) to address the adoption and meaningful use of electronic medical records. The South African e-Health strategy and the National Health Normative Standards Framework for Interoperability in eHealth in South Africa documents both recommend the adoption of EMRs. Much work has been done to establish a baseline for standards to ensure interoperability and data portability of healthcare applications and data. However, even with the increased focus on e-Health, South Africa remains excessively reliant on paper-based medical records. Where health information technologies have been adopted, there is lack of coordination between and within provinces, leading to a multitude of systems and vendors. Thus there is a lack of systematic adoption and meaningful use of EMRs in South Africa. The main objective of this research is to develop the components required to engender meaningful use of electronic medical records in the South African healthcare context. The main contributors are identified as EMR certification and consistent, proper use of certified EMRs. Literature review, a Delphi study and logical argumentation are used to develop the relevant components for the South African healthcare context. The benefits of EMRs can only be realized through systematic adoption and meaningful use of EMRs, thus this research contributes to providing a road map for engendering the meaningful use of EMRs with the ultimate aim of improving healthcare in the South African healthcare landscape.
