Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Telemedicine is de ned as an electronic exchange of medical information and/or the delivery of clinical health care over a distance, by means of Information and Communication Technology (ICT). South Africa is faced with the problem of providing health care to a population in urban, as well as across vast rural areas. In addition to this, the South African health care system must deal with economical imbalances and a shortage of human resources to provide quality health care. Telemedicine services could provide a solution. Since the introduction of the rst national telemedicine services initiative in the late 1990s, a number of South African telemedicine services have been implemented in the public health care system. The majority of these telemedicine services have been prone to failure and many were prematurely terminated. The circumstances which in uence the failure or success of these services are not unknown. The lack of insight, and the high failure rate of telemedicine services implemented in the South Africa were the reasons for conducting this study. The purpose of the study is to assess telemedicine services implemented in the Western Cape public health care sector. The purpose is also to provide recommendations for improving the current and future telemedicine services in the Western Cape and other provinces. A telemedicine services assessment was conducted on a total of 26 telemedicine services identi ed at 6 health care facilities located in the Western Cape. The assessments were based on the TeleMedicine Services Maturity Model (TMSMM), which was developed speci cally for the purpose of assessing telemedicine services. The TMSMM capability statements were used as a yardstick to assess the maturity of each of the elements of telemedicine services in terms of the three service level groups (micro-,meso- and macro-level) and ve telemedicine domains (man, machine, material, method and money). The assessment process included: (i) the identi cation of telemedicine services at the selected health care facilities; (ii) the gathering of the relevant telemedicine service data by means of structured interviews; (iii) the transformation of the complex ow of information into Data Flow Diagrams (DFDs); (iv) the loading of telemedicine services data into a data warehouse; and (v) the analysis of data by means of On-Line Analytical Processing (OLAP), as well as box-and-whisker plots and statistical correlations. Based on the results of the TMSMM assessment, an electronic questionnaire was developed and administered amongst health care workers throughout the entire Western Cape. The questionnaire con rmed that the ndings from the TMSMM assessment are indeed representative of the entire Western Cape. The assessment of the telemedicine services provides information about the elements which a ect the success or failure of these services. This therefore addresses the initial research problem and ful ls the purpose of the study. These results were used as an input to the analysis of strengths, weaknesses, opportunities and threats (SWOT) of the delivery of telemedicine services in the Western Cape public health sector. For future references and studies, the SWOT analysis provides a point of departure for a strategic telemedicine services framework for a province like the Western Cape. / AFRIKAANSE OPSOMMING: Telegeneeskunde, per de nisie, behels die deel van mediese inligting en/of die lewering van kliniese gesondheidsdienste oor 'n afstand, deur middel van inligting en kommunikasie tegnologie (ICT). Telegeneeskunde dienste is moontlik een van die oplossings vir die lewering van gesondheidsdienste vir 'n bevolking wat versprei is oor 'n groot landelike gebied binne 'n publieke gesondheidsektor wat mense hulpbronne kort om kwaliteit gesondheidsorg te lewer. Die publieke gesondeheidstelsel van Suid Afrika het 'n drie-dubbele las van siektes, ekonomiese wanbalans and 'n tekort aan mediese praktisyns. Sedert die eerste nasionale inisiatief vir telegeneeskunde dienste in die laat 1990s bekend gestel is, is 'n paar telegeneeskunde dienste in die publieke gesondheidsektor van Suid Afrika geïmplementeer. Die meerderheid van hierdie dienste blyk onsuksesvol te wees. The faktore wat die implementeringsukses beïnvloed is nog nie goed nagevors nie. Die doel van hierdie studie is om telegeneeskunde dienste wat in die Wes- Kaap publieke gesondheidsektor geïmplementeer is te ondersoek. Die doel is verdermeer om aanbevelings te maak met die oog op die verbetering van bestaande en toekomstige dienste in die Wes-Kaap asook ander provinsies. Eerstens is 'n telegeneeskunde diens assessering uitgevoer op 'n totaal van 26 dienste 6 fasiliteite. Hierdie assesserings is gebasseer of the Telegeneeskunde Diens Volwassenheidsmodel (TMSMM), wat ontwikkel is spesi ek met die doel om telegeneeskunde dienste te assesseer. Dit word gedoen deur die dienste te meet in terme van drie vlakke (mikro-, meso- en macrovlak) en vyf domeine (man, masjien, materiaal, metode en geld). Die TMSMM vermoeë-stellings word as maatstaaf gebruik. Die assesseringsproses sluit in (i) die identi sering van telegeneeskunde dienste by die aangewese gesondheidsfasiliteite; (ii) die versameling van relevante telegeneeskunde data deur middel van gestruktureerde onderhoude; (iii) die transformasie van komplekse inligtings vloei na data vloeidiagramme (DFDs); (iv) die laai van telegeneeskundige dinste data in 'n databasis; and (v) die analyse van data deur middel van aanlyn analitiese verwerking (OLAP) sowel as boxen- snorbaard gra k en statistiese korrelasies. Gebasseer op die resultate van die TMSMM assesseringsproses, is 'n elektroniese vraelys ontwikkel en geadministreer onder gesondheidswerkers regoor die Wes-Kaap ten einde te bevestig of die gevolgtrekkings van die TMSMM assessering die hele provinsie verteenwoordig. Die assessering van die telegeneeskundige dienste verskaf inligting in terme van die faktore wat die sukses van telegeneeskundie dienste beïnvloed. Sodoende word die aanvanklike navorsingsprobleem aangespreek. Hierdie resultate is toe gebruik as inset vir die analise van die sterk punte, swak punte, geleenthede en bedreigings (SWOT) in die publieke gesondheidsektor van die Wes-Kaap in terme van telegeneeskundige dienste. Hierdie SWOT-analise kan in die toekoms gebruik word as vertrekpunt vir die ontwikkeling van strategiese raamwerk vir die implementering van telegeneeskundige dienste in 'n provinsie soos die Wes-Kaap.

This thesis reports from a telecare evaluation in a Norwegian municipality (2012-2016). The project was established to provide domestic results from a hitherto new field in the country to underpin future policy. This evaluation includes pre- and post-implementation data collection, which has been scarce in telecare. The methodological approach was realist evaluation that seeks to explore how telecare works, for whom, why and in which circumstances – or why it does not work. The research aimed to explore the hypothesis elicited from national policy documents: ‘If telecare is used, then people are enabled to remain safe in their own home for longer’. Various methods were used to gather data from multiple stakeholders as they have different knowledge about how the implementation developed. The methods in this evaluation included literature reviews, observations, and sequential interviews with users and relatives in addition to sequential focus groups with frontline staff. Realist evaluation was particularly suitable in demonstrating how and why telecare is useful to some users but not to others. Telecare had to match users’ abilities and needs for them to benefit from it. Telecare operates in a dynamic context, and therefore requires adjustment according to the user’s current situation, taking into account changes as they occur. This appears to have been often underestimated. Telecare holds a different position from other devices and technologies in people’s everyday life, which also needs to be acknowledged. Correct assessment is significant for users to obtain the intended effect from telecare. When telecare is correctly adjusted to users, it increases safety, which is essential for enabling older people to remain living at home. Several challenges in establishing telecare projects are identified and alternative ways to understand multi-disciplinary partnerships are suggested. By using realist evaluation the findings are nuanced and point to elements that are significant for achieving the intended outcomes.

Factors such as poverty, ethnicity, socio-economic status, poor infrastructure and governance, etc., are some of the reasons that effective and proven prevention and treatment interventions for most of the major causes of mortality and morbidity in the developing world continue to fail. Chronic diseases require complex interventions that these countries simply cannot maintain. Diabetes mellitus (DM) is a chronic disease that is on the rise worldwide. This disease is a lifestyle disease, which means, that it is brought on by poor health habits. Statistics show that 285 million (6.4%) people aged between 20 and 79 years will be affected by Diabetes in 2010 and a staggering 439 million (7.7%) by 2030. This is a projected growth of 69% in developing countries and 20% in developed countries. The findings from studies conducted from 1993 to 2003 in Sub-Saharan Africa, particularly in South Africa, around the health care services for diabetes highlights many challenges. Sadly, the challenges 10 years after that study, are very similar. The conditions of people with Diabetes can be improved through regular monitoring of patients, improvement and monitoring of health care provided, education on healthy lifestyle, as well as education on the importance of adherence to treatment plans for the successful management of the condition. The diabetes endemic in South Africa is exacerbated by the manual functions that are performed in all aspects of monitoring and management of the disease. With the advancements that have been made in ICT and the many apps that already exist for healthcare, it is sensible to state that ICT can assist in the monitoring and management of diabetes. Another factor that is considered is that of patient-centred care. The huge number of people who need acute care and treatment in hospitals and clinics have forced a previously caring environment, to turn into a cold, almost production line affair. The sick wait in long queues and are ushered in and out of the consulting rooms as fast as possible without even as much as a “hallo”. This has left a void in the healthcare delivery to South Africans which should never have been removed in the first place, namely patient-centred care. This means that the patient is at the centre of the treatment and fully involved in the decisions about his/her health. Every patient deserves to be recognised as a human-being and treated with dignity and respect. Treatment plans for long term chronic care patients such as diabetics, should be thoroughly discussed with the patient and they should believe and comit themselves to the treatment plan. These plans are life-long and require dedication and as it is vital that patients are part of decision making and understand fully what they are expected to do. Bearing this in mind, this study has investigated the needs and care plans for people with diabetes. Specialist in the field of diabetes were interviewed and recognised care plans for diabetes such as those from WHO, IDF and SEMSDA were studied. This study also established, that by practising a patient-centred approach the adherence to a treatment plan is likely to be higher. The strategy developed involves the person with diabetes, the healthcare worker and the support structure in the care plan of the diabetic. The use of ICT as part of the solution must consider the patient-centred requirements for using IT so that the people using the strategy are comfortable and not intimidated by the technology. The need to incorporate e-health into governments’ healthcare plans has been growing over the last decade. The GSMA conducted research into mobile health opportunities in South Africa and found that SA now has a penetration of 98% and that this is the ideal medium to address the inaccessibility and inequality of healthcare in SA. The causes identified as playing a major role in the rise in diabetes were identified and it was determined that through the implementation of an ICT strategy for diabetes care, many of these can be addressed. These include the use of technology for, improved monitoring and management, increased diabetes awareness and education, and promotion of healthy lifestyle. The study focuses on the self-management aspect of diabetes and produces a strategy that incorporates various ICT solutions that would assist in the daily aspects of diabetes care, as well as follow a patient-centred approach to diabetes care. This strategy developed in this study does not need any intervention from government as it is driven by the people who have diabetes and their healthcare workers, with the aid of the technology that they currently have on hand.

The COVID pandemic led to a sudden expansion of telehealth in the delivery of nursing services. At the same time, nursing education was forced to extend clinical learning to online approaches. However, telehealth clinical experiences are limited in the nursing curricula of entry-level programs. Nursing simulation is an educational activity that prepares students for clinical practice by supporting the learning of fundamental clinical competencies. This study was designed to explore prebriefing methods for simulation to prepare entry-level nursing students for telehealth patient care visits. Standardized patient (SP) methodology was used to simulate a telehealth video conferencing call for an infectious disease case interview. Simulations were conducted remotely using Zoom technology with breakout rooms adhering to Healthcare Simulation Standards of Best PracticeTM, and informed by NLN Jeffries Simulation Theory and Experiential Learning Theory. The experiment compared two different methods for prebriefing: traditional prebriefing with a narrated script and structured prebriefing with a narration script plus learners viewed a role modeling video and participated in guided reflection. Participants from one private university in the Northeast (N =126) were randomized and simulations took place over one semester. In conclusion, the standardized patient simulations were an effective teaching strategy for developing fundamental telehealth skills of therapeutic communication and confidence with patient safety. Learners in the structured prebriefing group had significantly higher scores for confidence in quality and safety, faculty assessed therapeutic communication, and simulation effectiveness. There were significant improvements of therapeutic communication scores over time for both groups, but there were no differences between groups. Future research might extend the explanations of how to best prepare learners for telehealth experiences; it is important to further explore telehealth clinical competencies with entry-level nursing students.

Thesis (PhD)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: A telemedicine service is a healthcare service (-medicine) that is delivered over a distance (tele-). The interest in the potential of telemedicine to increase the quality, accessibility, utilization, e ciency and e ectiveness of healthcare services is fuelled by the rapid development of information and communication technology (ICT) and connectivity. Despite this potential, the success rate of telemedicine services disappoints. Many mistakes in the implementation of telemedicine services are repeated over and over again and best practices are not captured and replicated. This study responds to the need for reference models for the assessment and optimization of telemedicine services in a consistent, systematic and systemic way. Maturity models are reference models that describe typical patterns in the development of organizational capabilities and depict a sequence of stages towards the desired state. Many reference models exist that are applicable to telemedicine services, but none of these provide guidance for the optimization of services, like a maturity model does. Many maturity models exist within a health systems context, but none of these can be applied "as is" to telemedicine services. In this study an iterative top-down design approach is followed to develop a Telemedicine Service Maturity Model (TMSMM). This model facilitates the assessment of a telemedicine service on micro, meso, and macrolevel along all the domains that comprise the telemedicine health system. Sets of capability statements are de ned, which follow each other in a cumulative manner, hence providing a maturation path towards the desired maturity state. These sets of capability statements provide yardsticks according to which quantitative values are allocated to an intangible concept, such as maturity. Once an individual service is assessed, further actions towards the optimization of the service can be derived from these yardsticks. The multidimensional design of the TMSMM, as well as the fact that capability statements facilitate the consistent quanti cation of maturity, makes it possible to analyze the aggregated results of cohort of services. To accomplish this, principles of business intelligence and data warehouse design are applied together with online analytic processing (OLAP) procedures. The TMSMM addresses the previously unful lled need for a reference model to assess and optimize telemedicine services in a consistent, systematic and systemic way. This study spans several academic and professional domains and thereby contributes to the scienti c world of telemedicine and ehealth. / AFRIKAANSE OPSOMMING: 'n Telegeneeskunde diens is 'n gesondheidsdiens (-geneeskunde) wat oor 'n afstand gelewer word (tele-). Met die snelle ontwikkeling van inligtings-en kommunikasietegnologie hou telegeneeskunde die potensiaal in om die kwaliteit, toeganklikheid, benutting, doelmatigheid en doeltre endheid van gesondheidsdienste te verhoog. Ten spyte van hierdie potensiaal, stel die aantal onsuksesvolle telegeneeskunde dienste teleur. Heelwat foute in die implementering van telegeneeskundedienste word oor en oor gemaak, terwyl die beste praktyke nie vasgevang en herhaal word nie. Hierdie studie is onderneem in reaksie op die behoefte aan 'n verwysingsmodel vir die assessering en optimering van telegeneeskunde dienste op 'n konsekwente, sistematiese en sistemiese manier. Volwassenheidsmodelle is verwysingsmodelle wat tipiese patrone in die ontwikkeling van organisatoriese vermoeëns beskryf. Dit stip 'n aantal fases neer wat uiteindelik behoort te lei na die ideale organisatoriese toestand. Daar bestaan verskeie verwysingsmodelle wat van toepassing is op telegeneeskunde dienste, maar geeneen daarvan gee leiding met die oog op die optimering van die diens, soos in die geval van 'n volwassenheidsmodel nie. In hierdie studie word 'n iteratiewe van-bo-na-onder ontwerpsbenadering gevolg om 'n telegeneeskunde volwassenheidsmodel (TMSMM) te ontwikkel. Hierdie model fasiliteer die assessering van 'n telegeneeskunde diens op 'n mikro-, mesoen makrovlak en met betrekking to al die fasette waaruit 'n telegeneeskunde stelsel bestaan. 'n Aantal vermoeëstellings is gede nieer. Hierdie stellings volg op mekaar en akkumuleer om sodoende 'n volwassenheidspad na die verlangde toestand aan te dui. Hierdie vermoeëstellings verskaf maatstawwe waarvolgens kwantitiewe waardes toegeken kan word aan 'n ontasbare konsep, soos volwassenheid. Sodra 'n individuele diens geassesseer is, kan verdere aksies met die oog op die optimering van die diens afgelei word. Die multidimensionele ontwerp van die TMSMM, tesame met die feit dat die vermoeëstellings volwassenheid op 'n konsekwente manier kwanti seer, maak dit moontlik dat die data van 'n kohort dienste saamgevoeg kan word met die oog op analise. Beginsels van besigheidsintelligensie, datastoorontwerp asook aanlyn analitiese prosessering (OLAP) word hiervoor ingespan. Die TMSMM spreek tot die voorheen onvervulde behoefte aan 'n verwysingsmodel waarmee telegeneeskunde dienste geassesseer in geoptimeer word in 'n konsekwente, sistematiese en sistemiese manier. Hierdie studie strek oor verskeie akademiese en professionele domeine en lewer sodoende 'n bydrae tot die multidissiplinêre wetenskapswêreld van telegeeskunde en e-gesondheid.

In a wireless and mobile communication paradigm, distribution and sharing of video content often occurs over unfriendly network environments constrained by lack of sufficient bandwidth, and prone to jitter, delay and packet losses. The research presented in this thesis proposed an assortment of application-specific optimizations designed to enable high-quality video communication over bandwidth constrained and unreliable channels. This assortment of solutions, termed herein as the Application Specific Video Coding and Delivery (ASVCD) toolkit, comprises of content and network adaptive approaches such as Region of Interest (ROI) video coding, Multiple Representation Coding (MRC), and Multiple Representation Coding of the Region of Interest (ROI + MRC). Thus, the effectiveness of ROI based video-coding in facilitating diagnostically lossless delivery of surgical videos over very low bandwidth channels was studied in this thesis. Furthermore, to facilitate error resilient video delivery over channels prone to burst losses and signal loss intervals, the MRC scheme was presented in this thesis. Finally, the thesis proposed a scheme for unequal protection of the ROI in the video by using the MRC scheme to effectively enable a distance learning application. To summarize, the ASVCD toolkit contributed in enabling high-quality video communications applications to become seamless and pervasive.

Transmission of medical images, that mandate lossless transmission of content over WLANs, presents a great challenge. The large size of these images coupled with the low acceptance of traditional image compression techniques within the medical community compounds the problem even more. These factors are of enormous significance in a hospital setting in the context of real-time image collaboration. However, recent advances in medical image compression techniques such as diagnostically lossless compression methodology, has made the solution to this difficult problem feasible. The growing popularity of high speed wireless LAN in enterprise applications and the introduction of the new 802.11n draft standard have made this problem pertinent. The thesis makes recommendations on the degree of compression to be performed for specific instances of image communication applications based on the image size and the underlying network devices and their topology. During our analysis, it was found that for most cases, only a portion of the image; typically the region of interest of the image will be able to meet the time deadline requirement. This dictates a need for adaptive method for maximizing the percentage of the image delivered to the receiver within the deadline. The problem of maximizing delivery of regions of interest of image data within the deadline has been effectively modeled as a multi-commodity flow problem in this work. Though this model provides an optimal solution to the problem, it is NP hard in computational complexity and hence cannot be implemented in dynamic networks. An approximation algorithm that uses greedy approach to flow allocation is proposed to cater to the connection requests in real time. While implementing integer programming model is not feasible due to time constraints, the heuristic can be used to provide a near-optimal solution for the problem of maximizing the reliable delivery of regions of interest of medical images within delay deadlines. This scenario may typically be expected when new connection requests are placed after the initial flow allocations have been made.

Thesis (MScEng)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: South Africa has a great number of patients and not enough medical expertise to attend to their patient needs. The South African Department of Health (DoH) has recognised the potential benefit of the Picture Archiving and Communication System (PACS) to address the health needs of rural patients who do not have access to specialised medical care. PACS allows specialist remote access to patient information to assist the diagnosis and treatment process remotely. South African healthcare institutions have been implementing PACS for over a decade, in an attempt to address the health needs of rural patients that do not have access to specialised medical care. Despite numerous deployment attempts, and the DoH’s support for PACS, the system is not operating successfully in South Africa. PACS was chosen due to its proven success as an appropriate technical system in most international hospitals of first and third- world countries (van Wetering, 2008) (Horri, 2010). However, specifications, guidelines and best practice operational methods for the appropriate PACS technical structure are lacking in South African literature and in governmental strategies. Additionally, there are no guidelines for implementation or support for hospital decision makers to manage the system and enterprise change. The purpose of this thesis is to (a) define a PACS technical and operational structure suited for the South African public healthcare environment and, (b) to develop guidelines for implementation and optimisation of PACS for managing the system and the enterprise change and progressively reach the defined structure. A combination of literature research, field observations and focus group discussions led to the understanding of the current (“As-Is”) PACS healthcare delivery system in South Africa and its barriers. Three types of PACS structures were found to be currently available: a DICOM-only image management system; a vendor supplied PACS; and a super-PACS. It was found that currently very few PACS systems in South Africa are operational and integrated with other healthcare institutions. This was due to a combination of factors: a) the complex, long chain of interdependent process steps and domains; b) vendor imposed limitations and propriety data formats; in combination with c) a lack of governing standards to ensure integration of digital PACS systems within the healthcare delivery environment; and lastly d) key decision makers lack the expert knowledge necessary to make informed decisions to deploy and manage PACS optimally. Further research led to establishing the (“To-Be”) PACS technical and operational structure suited for the South African public healthcare environment. Research has shown that the suited PACS technical and operational structure is a hospital-owned PACS system, free from vendor-imposed limits. The system consists of two databases, one with patient information and the other with patient images. The two databases are integrated by a hospital-owned server, which accesses the separate data files by means of patient identity keys. The requirements for the PACS implementation and optimisation guidelines for managing the system and the enterprise change to progressively reach the defined structure were developed. Different Enterprise Architectural Frameworks, as improvement and optimisation guidelines, were considered and compared in accordance with the requirements established. A maturity model (MM) was deemed as the appropriate framework to offer guidelines for managing PACS implementation and optimisation in the public medical sector of South Africa. After establishing that the available MMs were not sufficient in process or technical system detail, a new MM was developed for the deployment and maturation of PACS. The study was validated by means of usability study, user acceptance and goal checking, through focus group discussion and expert review. Users found the model to be a suitable deployment and optimisation guide, as well as a strategic planning tool. Verification was achieved by means of requirement analysis and consistency checking through the focus group discussions. It was found that it is needed to define a PACS technical and operational structure is suited for the South African public healthcare environment and that the guidelines for implementation and optimisation of PACS for managing the system and the enterprise needs to change to reach the defined structure functional. Implementing the use of PACS MM to reach the defined structure in South Africa will assist in improving healthcare delivery in South Africa and improving PACS system operation. / AFRIKAANSE OPSOMMING: Suid-Afrika het 'n groot aantal pasiënte en nie genoeg mediese kundiges om aan hul pasiënt behoeftes te voorsien nie. Die Suid-Afrikaanse Departement van Gesondheid (DvG) erken die potensiële voordeel van ‘n Foto Argief en Kommunikasie Stelsel (PACS) om die gesondheidsbehoeftes van alle Suid-Afrikaners aan te spreek – tot die landelike pasiënte wat nie toegang tot gespesialiseerde mediese sorg het nie. PACS laat spesialiste toe om toegang te kry tot afgeleë pasiënt inligting, en daardeur fasiliteer dit die diagnose- en behandelingsproses. Suid-Afrikaanse gesondheidsorginstellings poog al vir meer as ‘n dekade om PACS te implementeer, om daardeur die gesondheidsbehoeftes van landelike pasiënte wat nie toegang tot gespesialiseerde mediese sorg het nie, aan te spreek. Ten spyte van talle ontplooiings pogings, en die DvG se steun vir PACS, is die stelsel steeds nie suksesvol in Suid-Afrika nie. PACS is gekies as ‘n oplossing, as gevolg van die sisteem se bewese sukses as 'n geskikte tegniese stelsel in meeste internasionale hospitale in eerste en derde wêreld lande (van Wetering, 2008) (Horri, 2010). Suid-Afrikaanse regering strategie en literatuur het egter ‘n gebrek aan spesifikasies, riglyne en beste- praktyk operasionele metodes vir die toepaslike PACS tegniese struktuur. Benewens is daar geen riglyne vir die implementering en ondersteuning van die stelsel en die onderneming se verandering vir hospitaal besluitnemers nie. Die doel van hierdie tesis is om (a) 'n PACS tegniese en operasionele struktuur, geskik vir die Suid-Afrikaanse openbare gesondheidsorg omgewing te definieer, en (b) riglyne vir die implementering en afronding van PACS vir die bestuur van die stelsel en die onderneming se verandering teen doel om progressief die gedefinieerde struktuur te bereik. 'n Kombinasie van literatuur navorsing, veldwaarnemings en fokusgroepbesprekings het gelei tot die begrip van die huidige ("as- is") PACS gesondheidsorg proses in Suid-Afrika en die hindernisse daarvan. Drie tipes PACS strukture is tans beskikbaar in SA: 'n DICOM (net-mediese- beelde) beheer stelsel, 'n verkoper verskafde PACS, en 'n super-PACS. Deur uitgebreide navorsing is daar gevind dat baie min PACS stelsels in Suid-Afrika tans operasioneel en geïntegreer is met ander gesondheidsorg instellings. Dit was te danke aan 'n kombinasie van faktore: a) die kompleks, lang ketting van interafhanklike proses stappe en gebiede; b) ondernemer opgelê beperkings en ordentlikheid data formate; in kombinasie met c) 'n gebrek aan beheer standaarde integrasie van digitale PACS stelsels om te verseker binne die lewering van gesondheidsorg-omgewing, en laastens d) sleutel besluitnemers nie die deskundige kennis wat nodig is om ingeligte besluite te sit en te bestuur PACS optimaal te benut. Verdere navorsing het gelei tot die vestigting van die geskikde("to-be") PACS tegniese en operasionele struktuur, vir die Suid-Afrikaanse openbare gesondheidsorg omgewing. Die geskik PACS tegniese en operasionele struktuur bestaan uit ‘n hospitaal-besitde PACS stelsel, vry van ondernemer-opgelegde grense. Die stelsel bestaan uit twee databasisse, een met 'n pasiënt inligting en die ander met dei pasiënte se mediese beelde. Die twee databasisse geïntegreer deur 'n hospitaal-besitde-rekenaarbediener, wat toegang tot die afsonderlike data lêers het deur middel van die unieke pasiënt nommers. Die vereistes vir die PACS implementering en afrondings riglyne, vir die bestuur van die stelsel en die ondernemings veranderinge, is ontwikkel. Verskillende ondernimings argitektuur raamwerke is oorweeg en vergelyking in terme van hulle vermoe om aan die gesigde vereistes et voldoen. As ‘n resultaat is die volwassenheid model (MM) beskou as die toepaslike raamwerk om riglyne vir die bestuur van PACS implementering en afronding in die openbare mediese sektor van Suid-Afrika te bied. Na die beskikbare MMs geasseseer was en nie voldoende bewys is, was 'n nuwe MM ontwikkel vir die implementeering en afronding van PACS. Die studie was gevalideer deur middel van die bruikbaarheid studie, gebruikers aanvaarding en doelwit asseseering, deur middel van fokusgroep besprekings en kundige oorsig. Gebruikers het gevind dat die model geskikte as implementeerings en afrondings gids, sowel as 'n geskikte strategiese beplanning hulpmiddel is. Verifikasie is bereik deur middel van vereiste-ontleding en konsekwentheid analiseering deur die fokusgroep besprekings en spesifikasie analise. Die PACS tegniese en operasionele struktuur wat definieer was, is geskik vir die Suid-Afrikaanse openbare gesondheidsorg omgewing en dat die riglyne vir die implementering en afronding van PACS funksioneel is . Die implementering en gebruik van die gedefinieerde struktuur deur mideel van die PACS MM in Suid-Afrika, sal help in die verbetering van gesondheidsorg dienslewering en die verbetering van PACS stelsel operasie.
